CARRIER AGGREGATION FEEDBACK METHOD, DEVICE AND SYSTEM FOR DIFFERENT TDD UPLINK/DOWNLINK CONFIGURATIONS |
摘要 |
Disclosed are a carrier aggregation feedback method, device and system for different TDD uplink/downlink configurations, relating to communication technologies. The number M of subframes requiring ACK/NACK feedback in a current uplink subframe is determined according to a TDD uplink/downlink configuration that corresponds to each carrier and is used for determining a timing relationship based on which a UE reports ACK/NACK feedback information of the carrier, and then ACK/NACK feedback information transmitted by a terminal device in the current uplink subframe and a candidate channel resource used for channel selection are determined according to the value of M, so as to transmit the ACK/NACK feedback information in the candidate channel resource by using PUCCH format 1b in combination with channel selection. |
