HYBRID MULTIBAND AND SUBBAND SCHEDULING IN MULTI-USER SUPERPOSITION TRANSMISSION

WIPO Patent Application WO/2017/143503

A1

In one aspect, a RAN node determines UE candidate sets for MUST scheduling where each set includes near UE and far UE MUST positions. The node orders the UE candidate sets according to a scheduling performance metric for each UE candidate set, evaluated with respect to the entire band. The node resolves MUST pairing conflicts by excluding, from the UE candidate sets, any UE candidate set that includes a UE that (a) is also present in a UE candidate set having a better scheduling performance metric and (b) has an inconsistent MUST position for interference cancellation with respect to the better UE candidate set, to obtain a reduced set of UE candidate sets. The node performs subband scheduling on each subband, using either MUST or OMA transmission scheduling for each subband. The reduced set is used for MUST scheduling. MUST/OMA subband conflicts may also be resolved.
