1. A method for transmitting relay link uplink acknowledgment/negative acknowledgment feedback information, comprising:
determining a timing relationship for transmitting the uplink feedback information according to a relay subframe configuration; and a relay station determining an uplink relay subframe for transmitting the uplink feedback information according to the timing relationship, and transmitting the uplink feedback information via the uplink relay subframe, wherein the step of determining the timing relationship for transmitting the uplink feedback information according to the relay subframe configuration comprises: the relay station acquiring the relay subframe configuration and determining, according to the acquired relay subframe configuration, the timing relationship from pre-determined correspondence, wherein the correspondence is between the relay subframe configuration and uplink feedback information transmission timing relationship, or the correspondence is between subframe locations of relay link downlink service transmission and corresponding uplink feedback information transmission; or a base station determining the timing relationship according to the relay subframe configuration, and sending indication information for indicating the timing relationship to the relay station; wherein as to subframe uplink/downlink configuration 1, the timing relation is determined to be that:
if only subframe 3 is configured to be an uplink relay subframe, the corresponding feedback information of the relay link downlink service data transmission in subframe 4 of number n radio frame will be transmitted in uplink relay subframe 3 of number n+1 radio frame; andif only subframe 8 is configured to be an uplink relay subframe, the corresponding feedback information of the relay link downlink service data transmission in subframe 9 of number n radio frame will be transmitted in uplink relay subframe 8 of number n+1 radio frame; or wherein as to subframe uplink/downlink configuration 2, the timing relation is determined to be that:
if only subframe 2 is configured to be an uplink relay subframe, the corresponding feedback information of the relay link downlink service data transmission in subframe 3 of number n radio frame will be transmitted in uplink relay subframe 2 of number n+1 radio frame, and the corresponding feedback information of the relay link downlink service data transmission in subframe 9 of number n radio frame will be transmitted in uplink relay subframe 2 of number n+2 radio frame; andif only subframe 7 is configured to be an uplink relay subframe, the corresponding feedback information of the relay link downlink service data transmission in uplink relay subframe 4 and/or 8 of number n radio frame will be transmitted in uplink relay subframe 7 of number n+1 radio frame; or wherein as to subframe uplink/downlink configuration 3, the timing relation is determined to be that:
if subframe 3 is configured to be an uplink relay subframe, the corresponding feedback information of the relay link downlink service data transmission in subframe 9 of number n radio frame will be transmitted in uplink relay subframe 3 of number n+1 radio frame; or wherein as to subframe uplink/downlink configuration 4, the timing relation is determined to be that:
if subframe 3 is configured to be an uplink relay subframe, the corresponding feedback information of the relay link downlink service data transmission in subframe 4 of number n radio frame will be transmitted in uplink relay subframe 3 of number n+1 radio frame. |
