Abstract:
1. A method, performed in a wireless communication system, for sending a feedback message for an automatic repeat request, comprising: recording an ACK type in a first field, wherein the ACK type indicates one of a selective ACK type, a cumulative ACK type, a cumulative-selective ACK type, and a cumulative-bulk ACK type; determining a last block sequence number of successive blocks that are successfully received by a first wireless communication device from a second wireless communication device, to record the determined last block sequence number in a second field; recording, in a third field, types of groups of successive blocks that are successfully or unsuccessfully received after the last block sequence number if the ACK type is the cumulative-bulk ACK type; determining lengths of the groups to record the determined lengths of the groups in a fourth field if the ACK type is the cumulative-bulk ACK type; and sending, by the first wireless communication device, a feedback message including fields from the first field to the fourth field.
