    field of invention
    [0001] The present invention relates to the field of communication, and particularly to a method and system for processing an uplink control signaling feedback. Fundamentals of the invention
    [0002] In the long-term evolution system (abbreviated as LTE), the control signaling that needs to be transmitted on the uplink includes a negative acknowledgment/acknowledgement message (abbreviated as ACK/NACK), a synchronization request (abbreviated as SR), and information reflecting the physical downlink channel state (abbreviated as CSI), where the information takes three forms: channel quality indication (abbreviated as CQI), precoding matrix indicator (abbreviated as PMI), and ranking indicator (abbreviated as RI).
    [0003] When the user equipment (abbreviated as UE) has no physical uplink shared channel (abbreviated as PUSCH), the above uplink control signaling is sent on the physical uplink control channel (abbreviated as PUCCH).
    [0004] LTE defines a plurality of PUCCH formats, including PUCCH format 1/1a/1b and format 2/2a/2b, where format 1 is used to send the SR sync request from the UE, format 1a and 1b are used to send feedback a 1-bit ACK/NACK message and 2-bit ACK/NACK message respectively, format 2 is used to send the downlink channel status information (CSI) and to send the CSI and the ACK/NACK message simultaneously (when you need to send both types of uplink control signaling in the same subframe) when the subframe uses an extended cyclic prefix, format 2a is used to send the CSI and the ACK message 1-bit /NACK (when you need to send two types of uplink control signaling in the same subframe), and format 2b is used to send the CSI information and the 2-bit ACK/NACK message (when you need to send two types link control signaling ascending in the same subframe). However, when the user equipment has a PUSCH for simultaneous sending, in order to ensure single bearer ownership of the uplink, the uplink control signaling needs to be multiplexed into the PUSCH and sent along with the data. In this case, the feedback from the three forms of CSI (CQI/PMI and RI) can be periodic feedback and can also be aperiodic feedback, and Table 1: physical uplink channel corresponding to periodic feedback and aperiodic feedback, and private feedback is as shown in Fig. 1:

    [0005] In this case, as for CQI/PMI and RI that are sent as feedback periodically, if the UE does not need to send uplink data, then the CQI/PMI and RI that are sent as feedback periodically are transmitted in the PUCCH in the format of 2/2a/2b (PUCCH format 2/2a/2b), and if the UE needs to send uplink data, then the CQI/PMI and RI are sent on the PUSCH; and as for CQI/PMI and RI which are sent as feedback aperiodically, they are only transmitted in the PUSCH, and it is provided that when you need to send as feedback the periodic or aperiodic CSI in the same subframe, the periodic CSI will be abandoned and only the aperiodic CSI will be sent as feedback.
    [0006] In order to meet the requirements of the International Telecommunication Union-Advanced (International Telecommunication Union-Advanced, abbreviated as ITU-Advanced), the advanced long-term evolution system (abbreviated as LTE-A) as the evolution standard LTE software needs to support higher system bandwidth (up to 100 MHz) and needs to be backward compatible with the existing LTE standard. Based on the existing LTE system, the bandwidth of the LTE system can be combined to achieve higher bandwidth, and this technology is referred to as carrier aggregation technology (abbreviated as CA), where the technology to improve the rate of frequency spectrum utilization of the advanced IMT system and alleviate the lack of frequency spectrum resources, thereby optimizing the use of frequency spectrum resources.
    [0007] In an LTE-A system using carrier aggregation technology, the uplink broadband and downlink broadband may include a plurality of component carriers. When the base station has a physical downlink shared channel (abbreviated as PDSCH) that will be synchronized to the UE on a plurality of downlink component bearers and when the UE has no PUSCH to send in the current subframe, the UE needs to send as feedback the ACK/NACK message corresponding to the PDSCH of the plurality of downlink component bearers in the PUCCH. Currently, in the relevant art, a working assumption is that these ACK/NACK messages are sent on a UE-specific uplink component bearer; as for the SR information, the working assumption is that the UE only sends an SR and that SR information is sent on a UE-specific uplink component bearer; as for the periodic CSI information, the working assumption is that the CSI information is sent on a UE-specific uplink component bearer. The above working assumptions indicate that at most one uplink component bearer can send the PUCCH.
    [0008] However, once the LTE-A system meets the requirements on the uplink single bearer property, the PUCCH and PUSCH are allowed to be sent simultaneously. Due to the introduction of carrier aggregation, the PUSCH can be sent on a plurality of carriers simultaneously. Thus, several situations may arise where PUSCH and PUCCH on the same bearer are sent simultaneously, and PUSCH and PUCCH on different bearers are sent simultaneously, and the like. In this situation, in the relevant art, no technical solution regarding how to send the uplink control signaling is described, therefore, in the current LTE-A system, the base station and the UE do not have a common understanding on where to send the uplink control signaling, causing the uplink control signaling cannot be processed correctly.
