Abstract
An enhanced round-robin scheduling (RRS) scheme for multi-pair multi-input-multi-output relay systems is proposed, where the relay is equipped with a large-scale antenna array and performs minimum mean-square error (MMSE) data processing. Compared with the traditional RRS, significant sum rate performance improvement by setting the number of active user pairs to an appropriate value is achieved.
