Technical field of the present invention
[001] The invention relates to the field of communication, and specifically to a method to process power headroom and a terminal thereof. Background of the present invention
[002] In the long-term evolution system of the 3rd generation partnership project (3GPP LTE), the uplink power control is used to control the transmit power of the physical uplink channel to compensate for path loss and fading channel shadowing, and suppress inter-cell interference. The physical uplink channels controlled by the uplink power control comprise the physical uplink shared channel (PUSCH), the physical uplink control channel (PUCCH) and the sound reference signal (SRS). LTE uplink power control adopts the combined open loop and closed loop control mode.
[003] In the LTE system, the PUSCH transmit power of the user equipment (UE) in subframe i is defined as:
where, P is the configured maximum UE output power, the range of which is together determined by the maximum UE power determined by the UE power class, The system configured IE P-Max, the maximum output power tolerance configured (PCMAX tolerance), and the maximum power reduction (MRP) and the additional maximum power reduction (A-MPR) that are caused by the operating frequency band, the system bandwidth, the modulation order, the position of the transmission bandwidth, the configuration of the transmission bandwidth, and so on;
is the PUSCH transmit power that is estimated by the UE according to the base station's open-loop and closed-loop power control parameters and instructions, the path loss estimate, and the number of PUSCH resource blocks sent in subframe i; M(i) is the PUSCH transmission bandwidth in subframe i, which is represented by the number of resource blocks (RBs); P(j) is an open circuit power control parameter, which is the sum of a cell specific value P(j) and a UE specific O_NOMINAL_PUSCH value P(j); where, j=0 corresponds to the semi-persistent scheduled PUSCH transmission, j=1 corresponds to the dynamic scheduled PUSCH transmission, and j=2 corresponds to the random access response scheduled PUSCH transmission (the PUSCH transmission scheduled by the random access); α is the cell-specific path loss compensation factor. When j=0 or 1, α(j)e{0, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1}, and when j=2, α(j)=1. α=1 is full path loss compensation, and α<1 is partial path loss compensation; PL is the estimated downlink path loss that is measured and computed at the UE; Δ^(i) is a reported power offset for the modulation coding scheme (MCS); ef(i) is the current PUSCH power control setting state. According to the setting of the highest layer parameter, in the case of accumulated value power control,
and in the case of absolute value power control,
is a UE-specific closed loop correction value, which is also called the transmit power control command (TPC).
[004] In the LTE system, the PUCCH transmit power of the UE in subframe i is defined as:
in which, the definition of P is the same as that mentioned above;
is the PUCCH transmit power which is estimated by the UE according to the base station's open loop and closed loop power control instructions, the path loss estimate, and the PUCCH format sent in subframe i; P is an open circuit power control parameter, which is the sum of a cell specific value P and a specific value of O_NOMINAL_ PUCCH UE P ; O_UE_PUCCH ; Δ (F) is a reported power offset for the PUCCH (F) format, which is configured by the highest layer; h(n) is a value based on the PUCCH(F) format, in which, n is the CQI bit number information, and n is the HARQ bit number; eg(i) is the current PUCCH power control setting state,
. ^PUCCH is a UE-specific closed loop correction value, which is also called the transmit power control command (TPC).
[005] It should be noted that in the LTE system, in order to maintain the single-carrier character of the uplink signal, for the same UE, the PUSCH and PUCCH cannot be transmitted at the same time.
[006] To make the base station know the margin between the configured maximum output power that is defined by some UE at the given time and the estimated transmission power of the PUSCH that is programmed by the base station, so as to allow the base station know when the UE is power limited, providing the basis for the base station to schedule the resource scheduling and link adaptation of the PUSCH for the next time, and schedule the proper modulation coding scheme and bandwidth for the UE, and the UE needs to measure the power headroom (PH) of itself and report the same to the base station. In the LTE system, the power headroom of a given UE in subframe i is defined as:
which is the difference between the configured maximum output power defined by the UE and the transmit power of the PUSCH estimated by the UE. The power headroom that is obtained by measurement and computation is quantified with the range of [40,-23]dB, to the extent of 1dB as precision (the quantization ratio is shown in Table 1), and then transferred to the highest layer by the physical layer. The media access control layer (MAC layer layer for short) uses the 6-bit index to represent the quantized power headroom. The mapping relationship is shown in Table 1, and the 6-bit index is also called the power headroom.
[007] In addition, a power headroom report (PHR) is triggered by event. When the UE has PUSCH retransmission in the current subframe, there is event triggering the PHR, and the channel resource that the base station allocates for the PUSCH transmission of the UE is, according to a determined priority of the logical channels, sufficient to support the power headroom MAC control element and MAC protocol data unit (PUD) subheader thereof, the UE reports a 6-bit power headroom to the base station through the MAC control element of power headroom.
[008] The structure of the power headroom MAC control element is shown in Fig. 1. It is an octet, in which the upper 2 bits are reserve bits (R) set to 0, and the lower 6 bits are the reported power headroom (PH).
[009] It should be noted that in the LTE system, only the free height of power of the subframes that transmits the PUSCH is measured.
[010] Table 1: Power headroom free height quantification and report mapping diagram

[011] The LTE-Advanced system (called the LTE-A system for abbreviation) is the next generation evolution system of the LTE system. As shown in Fig. 2, LTE-A system adopts carrier aggregation technology to expand the transmission bandwidth. Each aggregate transporter is called a “component transporter”. Several component conveyors can be continuous or discontinuous, and can be on the same operating band or on different operating bands.
[012] In the LTE-A system, the user equipment can transmit PUSCHs on one component carrier (uplink), and can also simultaneously transmit several PUSCHs on several component carriers (uplink); and one or several PUCCHs can be transmitted on a component carrier (uplink). Furthermore, it is proposed in the PUCCH search in the LTE-A system that the PUSCH and PUCCH are simultaneously transmitted on a component carrier (uplink).
[013] Therefore, how to measure and report the power headroom in the LTE-A system that adopts conveyor aggregation becomes a problem to be readily solved. Invention Summary
[014] The invention mainly aims to provide a method to process power headroom and a terminal thereof, so as to at least solve the above problem.
[015] According to an aspect of the present invention, a method for processing the power headroom is provided, comprising: when transmitting the PUSCH and/or the PUCCH in the subframe and component carrier group, a terminal measuring the headroom of subframe power and the component carrier group; and the terminal reporting power headroom to a base station and indicating the type of power headroom reported in the report.
[016] According to another aspect of the present invention, a terminal is provided, comprising: a measurement module configured to measure the free height of power in the subframe and the component carrier group, when transmitting the PUSCH and/or the PUCCH in the subframe and the component carrier group; and a transmission module configured to report power headroom to the base station and which indicates the type of power headroom reported in the report.
[017] By the present invention, because the terminal also reports the type of the power headroom while reporting the power headroom, the problem that the reported power headroom cannot be distinguished in the related technology is solved. Thus, the type to which the power headroom belongs is specifically indicated by the type report while reporting the power headroom, avoiding confusion. Brief description of the drawings

Detailed description of the present invention
[019] The present invention is described below in detail with reference to the drawings in combination with the embodiments. It should be noted that the modalities and features of the same in the order can be combined with each other under the condition that there is no conflict.
[020] Fig. 3 shows a flowchart of a method for processing power headroom according to an embodiment of the present invention, comprising the following steps.
[021] Step 302: when transmitting the PUSCH and/or the PUCCH in the subframe and the component carrier group, the terminal measures the free height of power in the subframe and the component carrier group.
[022] Step 304: The terminal reports power headroom to a base station and indicates the type of power headroom reported in the report.
[023] In the modality, because the terminal measures the free height of power in the subframe and the component carrier group, when transmitting the PUSCH and/or PUCCH in the subframe and the component carrier group, the problem of measuring the free height of power in the LTE-A system is resolved, thus performing the measurement and reporting the terminal power headroom.
[024] Furthermore, because the terminal also indicates the type of power headroom while reporting power headroom, the problem that reported power headroom cannot be distinguished in the related technology is resolved. Thus, the type to which the power headroom belongs is specifically indicated by the type report while reporting the power headroom, avoiding confusion.
[025] The method for processing the power headroom provided by the present invention comprises the two parts, the measuring part and the reporting part: Part I. Power headroom measurement When transmitting the PUSCH and/or the PUCCH in the subframe i and the j component transporter group, the user equipment measures the free height of power PH(i, j) in subframe i and the j component transporter group, in which,
and the value of N is equal to the number of the component carriers group that is prescribed in the LTE-A protocol.
[026] Specifically, if each component carrier group includes only one component carrier, then N is equal to the number of component carriers.
[027] It comprises the following cases.
[028] 1) The user equipment only transmits the PUSCH in the subframe i and the component carrier group j.
[029] When only transmit the PUSCH in subframe i and the transport group of component j, the user equipment measures the free height of power PH (i, j) [dB] in the subframe i and the transport group of component j.
[030] That the user equipment only transmits the PUSCH in subframe i and the component carrier group j means that the user equipment transmits, in subframe i, a PUSCH on a component carrier in the component carrier group j, or transmits several PUSCHs respectively on multiple component carriers (ie, it transmits a PUSCH on each component carrier on the various component carriers), and the user equipment does not transmit the PUCCH on any component carriers in component carrier group j.
[031] Assuming that the PUSCH transmit power in subframe i and the component carrier group j, which is estimated by the user equipment, is P' (i, j) [dBm], and the configured maximum output power that is determined by the user equipment in subframe i and the j component transporter group is P ( j) [dBm], the power headroom that is measured by the user equipment in subframe i and the j component transporter group is:
which is the difference between the configured maximum output power that is determined by the user equipment in subframe i and the j component carrier group and the transmit power of the PUSCH transmitted in subframe i and the j component carrier group that is estimated by the user equipment.
[032] Specifically, when the user equipment transmits several PUSCHs in the component carrier group j, PPUSCH (i, j) is the sum of the transmit powers of several PUSCHs that are estimated by the user equipment.
[033] If the estimated transmit power of the PUSCH on each component carrier in the component carrier group j is PPUSCH (i, k)[dBm], where ktK is the sequential number of each component carrier in the component carrier group j, so

[034] The transmission power P' (i, k) [dBm] of the PUSCH, which is estimated by the user equipment is that which is estimated by the user equipment according to the parameters and instructions of open circuit power control and base station loop, the path loss estimate, and the number of blocks of the PUSCH resource programmed in subframe i and component carrier k and so on.
[035] Specifically,
dBm] where, M(i,k) is the bandwidth of the PUSCH which is transmitted in subframe i and the component carrier k, and is represented by the number of blocks of the resource (RB); P(h,k) is an open-loop power control parameter on the k-component conveyor; α is the compensation factor for the specific path loss on the component conveyor k; PL is the estimate of the uplink and downlink path loss of the component carrier k, which is measured and computed at the UE; ΔTF(i,k) is the reported power offset for the modulation coding mode of the PUSCH transmitted in subframe i and component carrier k; ef(i,k) is the current power control setting state of the PUSCH transmitted in subframe i and component carrier k.
[036] 2) The user equipment only transmits the PUCCH in subframe i and the carrier group of component j.
[037] When only transmit the PUCCH in the subframe i and the transporter group of component j, the user equipment measures the free height of power PH (i, j) in the subframe i and the transporter group of component j.
[038] That the user equipment only transmits the PUCCH in subframe i and the component carrier group j means that the user equipment transmits, in subframe i, a PUCCH on a component carrier in the component carrier group j, including the equipment of user that transmits several PUCCHs on one component conveyor in component conveyor group j, and the user equipment does not transmit the PUSCH on any component conveyor in component conveyor group j.
[039] Assuming that the PUCCH transmit power in subframe i and the j component carrier group, which is estimated by the user equipment, is P' (i, j) [dBm], and the configured maximum output power that is determined by the user equipment in subframe i and the j component transporter group is P(j) [dBm], the power headroom that is measured by the user equipment in subframe i and the j component transporter group is:
which is the difference between the configured maximum output power that is determined by the user equipment in subframe i and the j component transporter group and the transmit power of the PUCCH transmitted in subframe i and the j component transporter group that is estimated by the user equipment.
[040] Specifically, when the user equipment transmits several PUCCHs in the j component carrier group, P' (i, j) is the sum of the transmit powers of several PUCCHs that are estimated by the user equipment.
[041] If the estimated PUCCH transmit power on each component carrier in the component carrier group j is P' (i, k) [dBm], where ktK is the sequential number of each component carrier in the component carrier group j, so

[042] If the estimated transmit power of the PUCCH on the component carrier k is P'(i,k) [dBm], several PUCCHs are transmitted on the component carrier k, and the estimated transmit power of each PUCCH is P UCCH (i,k,c)[dBm], where c;C is the sequential number of each PUCCH on the component carrier k, then
that is, when transmitting several PUCCHs in subframe i and a component carrier in component carrier group j, the user equipment estimates, as for the component carrier, the transmit power of each PUCCH transmitted on the component carrier, and the sum of the transmit powers of the PUCCHs transmitted on the component carrier is used as the transmit power of the physical uplink channel transmitted on the component carrier, which is estimated by the user equipment.
[043] The PPUCCH transmission power (i, k, c) of the PUCCH, which is estimated by the user equipment, is that which is estimated by the user equipment according to the instructions and parameters of open circuit power control and base station loop, and the path loss estimate, and the PUCCH format with the sequential number of c transmitted in subframe i and the component carrier k.
[044] Specifically,
P(k) is an open-circuit power control parameter on the k-component conveyor; ΔF pucCH(F) is a reported power offset for the PUCCH(F) format of the PUCCH with the sequential number of c transmitted in the subframe i and the component carrier ke is configured by the highest layer; h(n) is a value based on the PUCCH(F) format, where n is the CQI bit number information, and n is the HARQ bit number; eg(i, k, c) is the current power control setting state of the PUCCH with the sequential number of c transmitted in subframe i and the component carrier k.
[045] 3) The user equipment transmits simultaneously the PUSCH and the PUCCH in the subframe i and the carrier group of component j.
[046] Assuming that a user equipment simultaneously transmits the PUSCH and PUCCH in subframe i and the transport group of component j, the user equipment measures the free height of power in subframe i and the transport group of component j.
[047] That the user equipment simultaneously transmits the PUSCH and PUCCH in subframe i and the component carrier group j means that the user equipment transmits, in subframe i, the PUSCH on one or more component carriers in the component carrier group j , and transmits the PUCCH on a component carrier in component carrier group j.
[048] Assuming that the PUSCH transmit power in subframe i and the component carrier group j, which is estimated by the user equipment, is P' (i, j) [dBm], the estimated PUCCH transmit power is P' ( i, j) [dBm], and the configured maximum output power that is determined by the user equipment in subframe i and the j component transporter group is P ( j) [dBm], the free height of power that is measured by the user in subframe i and the j component transporter group is: a:
Or b:
Or c:

[049] Specifically, PCMAX(j) = PC'MAx( j)= PC''MAx( j) is the configured maximum output power which is determined by the user equipment in subframe i and the transporter group of component j; or PC'MAx(j) is the maximum output power configured in the component transporter group j, which is determined by the user equipment, assuming that the user equipment only transmits the PUSCH in the component transporter group j; in which, the transmission setting (including modulation order, transmission width position, transmission width setting (number of physical resource blocks occupied) and so on) of the PUSCH assumed to be transmitted is the same as the setting of the PUSCH transmitted in subframe i and the component carrier group j. ''
[050] Specifically, PCMAx(j) is the maximum output power configured in the component transporter group j, which is determined by the user equipment, assuming that the user equipment only transmits the PUCCH in the component transporter group j; in which, the transmission configuration (including modulation order, transmission width position, transmission width configuration, and so on) of the PUCCH assumed to be transmitted is the same as the configuration of the PUCCH transmitted in the subframe i and the carrier group of component j.
[051] Or d: PH (i, j) and PHPUCCH(i, j) , which is defined as the same as a and c. Or e: PHPUCCH+PUSCH(i,j) and PHPUCCH(i, j), which is defined as the same as b and c. Or f: PH (i, j) and PH (i, j) , which is defined as the same as a and c. Or g: PHp'uccH+puScH(i, j) and PHpuScH(i, j), which is defined as the same as b and c. Or h: PHpuccH+puScH (i, j) and PHpuScH (i, j) and PHpuccH (i, j) , which is defined as the same as a and c. Or i: PHpuccH+puScH (i, j) and PHpuScH (i, j) and PHpuccH (i, j) , which is defined as the same as b and c.
[052] Or, the type and number of the free height of powers that are measured by the user equipment in the subframe i and the component carrier group j are configured by the upper layer signaling.
[053] Specifically, when the user equipment transmits several PUSCHs in the component carrier group j, P' (i, j) is the sum of the various transmit powers of the various PUSCHs that are estimated by the user equipment.
[054] If the estimated PUSCH transmit power on each component carrier in the component carrier group j is P' (i,k) [dBm], where ktK is the sequential number of each component carrier in the carrier group of component j, then
'
[055] Specifically, when the user equipment transmits several PUCCHs in the j component carrier group, P' (i, j) is the sum of the various transmit powers of the various PUCCHs that are estimated by the user equipment.
[056] If the estimated PUCCH transmit power on each component carrier in the component carrier group j is P' (i,k) [dBm], where kt K is the sequential number of each component carrier in the carrier group of component j, so

[057] If the estimated PUCCH transmit power on component carrier k is P' (i, k) [dBm], several PUCCHs are transmitted on component carrier k, and the estimated transmit power of individual PUCCHs is p^ CH(i,k,c)[dBm], where ctC is the sequential number of each PUCCH in the component carrier k, then

[058] In these cases above, the component carrier group j is a group of component carriers composed of one or more component carriers. These component carriers can be used to send the uplink signal. Each component carrier group can include only one component carrier.
[059] Specifically, the component carrier group can include all component carriers that use the same power amplifier (PA) in the user equipment. The component carrier group can also include all component carriers supported by the user equipment.
