MULTI-PORT-GROUP UPLINK CONTROL INFORMATION SIGNALING AND RELATED SYSTEMS AND METHODS

Abstract:

A method in accordance with aspects of the disclosure comprises receiving a plurality of downlink control information (DCI) signals, wherein each DCI signal is associated with a Demodulation Reference Signal (DMRS) Port Group (DMRS-PG) of a plurality of DMRS-PGs, and each DCI signal within the plurality of DCI signals contains a DMRS-PG Identifier (DMRS-PGID) identifying the associated DMRS-PG, performing one or more measurements associated with the each DCI signal, and generating a multi-port-group uplink control information (UCI) signal based on the one or more measurements associated with the each DCI, wherein the multi-port-group UCI signal contains an indication of whether the each DCI is successfully received. The indication can be explicitly contained in the UCI, or implicitly realized using scrambling sequences associated with DMRS-PGs to scramble the UCI.
