APPARATUS AND METHOD FOR UPLINK CONTROL SIGNALING IN MULTI-TRANSMISSION RECEPTION POINT OPERATION FOR NEW RADIO, AND DEMODULATION REFERENCE SIGNAL DESIGN

Title:

APPARATUS AND METHOD FOR UPLINK CONTROL SIGNALING IN MULTI-TRANSMISSION RECEPTION POINT OPERATION FOR NEW RADIO, AND DEMODULATION REFERENCE SIGNAL DESIGN

Document Type and Number:

WIPO Patent Application WO/2019/047950

Kind Code:

A1

Abstract:

Techniques discussed herein can facilitate multi-transmission reception point (multi-TRP) operation for new radio (NR). One example apparatus may be employed at a user equipment (UE), and may comprise: an interface configured to enable the UE to communicate with two or more TRPs; and a processor that is configured to generate uplink control information (UCI) for each o fthe TRPs, schedule single or multiple uplink channels to carry the UCI, so that the UCI is transmitted individually or in combination to the TRPs via the interface, wherein the uplink channels comprise NR physical uplink control channel (PUCCH) and/or NR physical uplink shared channel (PUSCH). Techniques discussed herein also can facilitate demodulation reference signal design for short physical uplink control channel carrying more than 2-bit UCI for new radio.
