FIELD OF THE INVENTION
The present invention relates to communication technologies and, in particular, to a power control technology. HISTORY OF THE INVENTION
The LTE-Advance network (Long Term Evolved-Advanced, Long Term Evolved-Advanced) is a communication network actively developed by the manufacturers, which is enhanced for the LET network, and is designed to provide a cost efficient network capable of reducing the delay, increase user data speed, and improve system capacity and coverage.
LTE technology supports fast scheduling and link adaptability. Therefore, an LTE network can allocate time frequency resources according to transient user requirements and channel state. In uplink scheduling technology, as the LTE network can subdivide frequency domain resources within multiple bands, the LTE network can schedule resources for more than one User Equipment (UE) in the same subframe.

The following describes a power control method provided in a version of the present invention with reference to Figure 7. As shown in Figure 7, the method includes the following steps:
Step 701: The base station obtains the maximum transmission power information supported by the aggregated carrier of the UE.
In step 701, the UE may send the maximum transmission energy information supported by the aggregated carrier of the UE to the base station, and the base station may obtain the maximum transmission energy information supported by the aggregated carrier of the UE by receiving information such as the system configuration information.
The UE's aggregate carrier may be of different granularities. Specifically, it can be carriers that are aggregated on the same antenna, or carriers that are assignable to the same power amplifier, or carriers that are assignable to the same band. For more details, see the versions described above.
Step 702: The base station sets the maximum transmit energy for the aggregated carrier of the UE according to the maximum transmit energy information supported by the aggregated carrier of the UE.
The details of the configuration of the maximum transmission energy for the aggregated carrier of the UE according to the maximum transmission energy information supported by the aggregated carrier of the UE may be: according to the maximum transmission energy information supported by the aggregated carrier of the UE , the base station sets the maximum transmission energy for the single carriers on the aggregated carrier respectively, or sets the sum of the maximum transmission energy of the single carriers on the aggregated carrier. Preferably, the sum of the maximum transmission energy of single carriers in the aggregated carriers is less than the maximum transmission energy supported by the aggregated carrier of the UE.
Optionally, the above setting process can be: the base station sets the maximum transmit power for the UE via a power control command.
Step 703: The UE obtains the aggregate carrier energy upper limit information in accordance with the maximum transmission energy configured by the base station for the UE's aggregate carrier, and sends the UE's aggregate carrier energy upper limit information to the base station.
The UE may obtain the aggregated carrier energy upper limit information according to the maximum transmit energy of the aggregated carrier of different granularities. Specifically, the aggregated carrier could be aggregated on the same antenna, and the UE could subtract estimated transmit energy of an antenna of the UE from the maximum transmit energy of the aggregated carrier that is aggregated on the same antenna, and use the result of the subtraction as the information of the aggregated carriers energy upper limit, and sends the energy upper limit information to the base station.
Similarly, the base station may obtain the energy upper limit information from the aggregate carrier of different granularities, for example, it may be carriers that are attributable to the same band or the same energy amplifier. For the detailed procurement process, see the versions described above.
Step 704: The base station adjusts the aggregate carrier transmit energy in accordance with the aggregate carrier energy upper limit information.
This step is similar to step 204.
The energy reporting method in this release improves energy control flexibility. Furthermore, as the sum of the maximum transmission energy configured by the base station for the aggregated carrier is less than the maximum transmission energy supported by the aggregated carrier of the UE, the UE never enters a power-constrained state, which ensures the reliable sending of Dice.
The following describes a method for reporting the upper energy limit with reference to Figure 8. The method includes the following steps:
Step 801: UE obtains a first threshold. The first threshold is used to trigger reports of the UE's aggregate carrier energy upper threshold information.
Specifically, the UE's aggregate carrier may include at least one component carrier group and at least one first carrier, or it may include at least one component carrier group, or include at least two first carriers, the component carrier group includes at least two second carriers, and the first carrier and the second carrier are single carriers.
The first threshold may be a change of the maximum transmission energy of a single carrier in the aggregated carrier of the UE and/or a change of the maximum transmission energy of a group of component carriers in the aggregated carrier of the UE. The change of the maximum transmit power of the UE aggregate carrier may be an increasing value or a decreasing value.
The first threshold may also be the value of the maximum transmission energy of the single carrier and/or the component carrier group of an aggregated carrier of the UE.
The first threshold may be configured by the base station for the UE, viz. for at least a single carrier and/or at least one component carrier group of the UE.
The single bearer of the aggregated bearer of the UE may be a single bearer belonging to no component bearer group, or single bearer belonging to a component bearer group.
In one version, the maximum transmission energy of each single carrier in the UE's aggregate carrier may be the smallest of the maximum transmission energy configured by the base station for each single carrier included in the UE's aggregate carrier and the UE's nominal maximum transmission energy. , or any value that falls between the upper limit of the maximum transmission energy and the lower limit of the maximum transmission energy, or the maximum transmission energy of the current time groove of the first carrier or the second carrier, or the maximum transmission energy determined by other calculation methods, which is not limited in this release.
Step 802: The UE triggers sending a maximum power height report when the UE determines that the change in the maximum transmit power of a single carrier and/or a component carrier group in the aggregated carrier of the UE reaches the first threshold , or determines that the value of the maximum transmission energy that is modified from a single carrier and/or a group of component carriers in the aggregated carrier of the UE reaches the first threshold.
Specifically, the UE may determine that the change of the maximum transmission power of a single carrier in the aggregated carrier of the UE is greater than or equal to the first threshold. For example, when determining that the increase or decrease of the maximum transmission power of a single carrier in the aggregated carrier of the UE is greater than or equal to the first threshold, and the UE triggers sending the upper energy threshold report; or, when determining that the value of the maximum transmission energy that is modified from a single carrier in the aggregated carrier of the UE is greater than or equal to the first threshold, and the UE triggers the sending of the upper energy threshold report; or, when determining that the value of the maximum transmission energy that is modified from a single carrier in the aggregated carrier of the UE is less than or equal to the first threshold, and the UE triggers the sending of the upper energy threshold report.
The UE may determine that the change of the maximum transmission power of a group of component carriers in the aggregated carrier of the UE is greater than or equal to the first threshold. For example, when determining that the increase or decrease of the maximum transmit power of a component carrier group in the UE's aggregate carrier is greater than or equal to the first threshold, and the UE triggers sending the upper energy threshold report; or, when determining that the maximum transmission power value that is modified from a component carrier group in the UE's aggregate carrier is greater than or equal to the first threshold, and the UE triggers the sending of the upper power threshold report; or when it determines that the value of the maximum transmission power that is modified from a group of component carriers in the aggregated carrier of the UE is less than or equal to the first threshold, and the UE triggers the sending of the upper power limit report. The maximum transmit energy of the component carrier group is equivalent to the maximum transmit energy of the component carrier group in previous releases, or it may be the maximum transmit energy of the component carrier group attribute. For example, the maximum transmit power of the component carrier group might be the sum of the maximum transmission energy of the second carriers in the component carrier group, and/or the smallest of the sum of the maximum transmission energy of the second carriers in the component carrier group and the nominal maximum transmission energy of the UE.
In step 801, when the first threshold is configured for the UE, the first threshold may be configured for all unique carriers in the aggregated carrier of the UE, the first threshold may be configured for at least a single carrier and/or at least one group of component carrier.
The maximum transmission energy mentioned above may be the maximum transmission energy of the current transmission time groove, or a weighted average of the maximum transmission energy of the current transmission time groove and historical transmission time grooves. For example, the maximum transmit energy may be the maximum transmit energy of the current transmit time slot of a single carrier in the aggregated carrier of the UE. In another example, the maximum transmit energy may be the maximum transmit energy of the current time groove of a group of component carriers in the aggregated carrier of the UE, or a weighted average of the maximum transmit energy of the current transmission time groove and historical transmission time grooves of the component carrier group in the UE's aggregate carrier.
In one version of the present invention, different threshold values may be configured for different unique carriers in the UE's aggregated carrier, and different threshold values may be configured for different component carrier groups. The limit on a single carrier may be the same or different from the limit on a component carrier group.
The power high limit report may be triggered either by a single carrier on the UE's aggregated carrier or a group of component carriers on the UE's aggregated carrier, or by both.
The Power High Bound Triggered Report mentioned above may be the Power High Bound report of at least a single carrier in the aggregated carrier, and/or the Power High Bound report of at least one component carrier group.
Step 803: The UE sends the high power limit report to the base station.
The UE may send the high power limit report of the current transmission time groove or a subsequent transmission time groove.
For details of the maximum transmit power of the UE's aggregate carrier, see the description in the previous versions.
The method for triggering high energy limit reporting in this release allows for high energy limit reporting in an aggregated carrier scenario.
The following describes a method for reporting the maximum transmit power with reference to Figure 9. The method includes the following steps:
Step 901: The UE determines that the maximum transmit power of the aggregate carrier of the UE changes; or
The UE obtains a second threshold, and determines that the change of the maximum transmit power of the aggregate carrier of the UE exceeds the second threshold.
The maximum transmission energy of the aggregated carrier of the UE may be the maximum transmission energy of a single carrier in the aggregated carrier, or the maximum transmission energy of a group of component carriers mentioned in previous versions, and may also be the transmission energy maximum of a component carrier group on the aggregated carrier. The maximum transmit energy of the aggregate carrier of the UE is equivalent to the maximum transmit energy of the attribute of the component carrier group mentioned in the first versions and may also be the maximum transmit energy of an attribute of the component carrier group. The second limit can be configured by a base station. Optionally, the base station sets the second threshold through wireless resource control messages.
Step 902: The UE sends the maximum transmit power of the aggregated carrier of the UE to the base station.
The maximum transmission energy of the aggregated carrier of the UE may be the maximum transmission energy of at least a single carrier and/or at least one group of component carriers in the aggregated carrier of the UE, and may also be the maximum transmission energy of the attribute. of the aggregated carrier.
After receiving the maximum transmit energy of the aggregated carrier of the UE, the base station keeps using the maximum transmit energy of the aggregated carrier of the UE. Once the second maximum transmit energy of the UE's aggregate carrier is subsequently received, the base station uses the second maximum transmit energy.
In one version of the present invention, the base station may request the UE to report the maximum transmit power of at least a single carrier on the UE's aggregated carrier. Optionally, the base station can send the request via an RRC or MAC message.
