Senior LTE (LTE-Advanced is referred to as LTE-A) system is the evolution system of future generation of LTE system.In order to support larger system bandwidth, and need backward compatibility LTE existing standard, introduced carrier aggregation technology, Fig. 3 is the schematic diagram of realizing carrier aggregation in the prior art LTE-A system, as shown in Figure 3, the LTE-A system adopts carrier aggregation (carrier aggregation) technological expansion transmission bandwidth, and the carrier wave of each polymerization is called one-component carrier wave (Component Carrier, referred to as CC), be called again a residential quarter (cell).A plurality of component carriers can be continuous, also can be discrete; Same frequency range (operating band) can be positioned at, also different frequency range can be positioned at.

For the HARQ-ACK response message under the transmission carrier aggregation scene, introduced a kind of new PUCCH form in the LTE-A system, be called the 3rd PUCCH form (PUCCH format 3).The prior art regulation, under the FDD system, needing the HARQ-ACK response message of transmission is at most 10 bits, under the TDD system, needing the HARQ-ACK response message of transmission is at most 20 bits, when the response message of transmission during greater than 20 bit, all HARQ-ACK response messages corresponding to PDSCH that comprise 2 streams of code words are carried out space binding (Spatial bundling) operation, be about to corresponding HARQ-ACK response message and carry out the logical AND operation.When adopting PUCCH format3 transmission, when the transmission bit number less than or equal to 11 bits, adopt the coded system of Rui De-Muller code (RM:Reed-Muller), when the transmission bit number greater than 11 bits, adopt the coded system of two Rui De-Muller code (Dual RM), the HARQ-ACK response message of needs transmission is divided into two parts, adopts respectively the RM rear transmission of encoding.

LTE-A system regulation: when UE need to be when same subframe sends HARQ-ACK response message and cycle CSI: if the HARQ-ACK response message that UE need to the transmit HARQ-ACK response message of corresponding main Serving cell only, UE adopts PUCCH format 2/2b to send HARQ-ACK response message and cycle CSI; Otherwise UE will destroy cycle CSI, and only send the HARQ-ACK response message.Why the LTE-A system adopts above-mentioned method, mainly is to want to guarantee downstream throughput performance.The LTE-A system also stipulates, when the cycle of a plurality of Serving cells CSI need to select the cycle CSI transmission of a Serving cell according to predefined priority when same subframe is transmitted, destroys the cycle CSI of other residential quarters.In the LTE-A typical application scenarios in (Rel-10 stage), the Serving cell that participates in carrier aggregation generally is 2, therefore, as long as the cycle CSI of Serving cell configuration is appropriate, in conjunction with certain scheduling restriction, cycle CSI can be controlled at relatively low scope with the HARQ-ACK response message at the probability that identical subframe sends, in like manner, the probability that the cycle CSI of a plurality of Serving cells sends simultaneously also can be controlled, thereby, be acceptable owing to destroying cycle CSI on the impact of systematic function.

But in the later later release of Rel-10, the typical application scenarios of carrier aggregation is being confined to 2 Serving cells, and along with the increase of Serving cell number, cycle CSI will increase at the probability that identical subframe bumps with ACK/NACK thereupon.If still according to the method for Rel-10, as long as the ACK/NACK response message comprises auxiliary serving cell, just destroy cycle CSI, the accuracy of the channel condition information that base station side obtains will descend, thereby also can affect the performance of downlink throughput capacity.Use PUCCH format3 while transmitting HARQ-ACK response message and cycle CSI information become a kind of possibility, and the cycle CSI information of using PUCCHformat3 to transmit simultaneously a plurality of Serving cells also becomes a kind of possibility, still, and present power control parameters h (n _CQI, n _HARQ, n _SR) definition only in the situation for PUCCH format3 transmitting HARQ-ACK response message, when PUCCH format3 transmits other UCI, need to redefine this power control parameters, otherwise the power control can't realize that PUCCH format3 transmits other UCI the time.
