Title:
GROUP COMMON CONTROL CHANNEL AND BANDWIDTH PART MANAGEMENT IN WIRELESS COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2019/183185
Kind Code:
A3
Abstract:
Methods, systems, and devices for wireless communications are described that support group common control channel and bandwidth part (BWP) management in wireless communications. A group downlink control channel transmission may include information from which each user equipment (UE) transmitting a negative acknowledgement (NACK) message can determine its unique retransmission resource assignment and a BWP for the retransmission. Different BWPs may be used for downlink transmissions to different UEs and downlink retransmissions responsive to the NACK messages may be transmitted using the original BWP of the UEs or a different BWP.
