FIELD: information technology.
SUBSTANCE: wireless communication system including a scheduling module which transmits scheduling messages to first and second wireless terminals having different scheduling characteristics, wherein each scheduling message includes a reference signal cyclic shift indicator and a resource assignment. The assignment of the downlink feedback resource to the first wireless terminal is indicated by the reference signal cyclic shift indicator in the corresponding scheduling message, and the assignment of the downlink feedback resource to the second wireless terminal is indicated by a corresponding resource assignment.
EFFECT: avoiding ambiguous physical hybrid ARQ indicator channel assignments between terminals multiplexed on the same time frequency resource, providing orthogonality between such terminals.
