SIGNALING ASPECTS FOR INDICATION OF CO-SCHEDULED DMRS PORTS IN MU-MIMO

摘要

The present disclosure relates to a mobile terminal, a base station, a method for data transmission/reception by a mobile terminal, and a method for data reception/transmission by a base station. The mobile terminal comprises circuitry which, in operation, receives a parameter defining a configuration for assigning to ports respective resources for carrying reference signals, the resources being grouped in a plurality of code division multiplexing, CDM, groups, and receives control information indicating one of the set of layer-to-port mapping combinations which is to be applied for arranging reference signals on ports of at least one CDM group for data transmission and/or reception, wherein the control information indicates a co-scheduling information for the at least one and/or at least a different CDM group of the plurality of CDM groups for the same data transmission and/or reception
