Abstract
A system and method for codebook feedback for data retransmissions are disclosed herein. In one embodiment, a method performed by communication device includes: receiving at least one of first downlink information and second downlink information from a communication node, wherein: the first downlink information is received before uplink grant information is received, and the second downlink information is received after the uplink grant information is received; generating at least one hybrid automatic repeat request acknowledgement (HARQ ACK), wherein the at least one HARQ ACK comprises at least one of: a first feedback information corresponding to the first downlink information, and a second feedback information corresponding to the second downlink information; and sending the HARQ ACK to the communication node in a feedback slot based on an uplink feedback timing indicated in the uplink grant information.
