Title:
TIMING ADVANCE DETERMINATION FOR UPLINK CONTROL CHANNEL WITH JOINT ACKNOWLEDGEMENT FEEDBACK FOR NETWORK OPERATIONS HAVING MULTIPLE TIMING ADVANCE GROUPS CONFIGURED PER SERVING CELL AND MULTIPLE CONTROL RESOURCE SET POOL INDEX VALUES CONFIGURED PER BANDWIDTH PART
Document Type and Number:
WIPO Patent Application WO/2023/150965
Kind Code:
A1
Abstract:
Wireless communication capabilities are disclosed that support determination of timing advance for a physical uplink control channel (PUCCH) in joint acknowledgement feedback mode of a network having multiple timing advance groups (TAGs) configured per serving cell and multiple control resource set (CORESET) pool index values configured per bandwidth part (BWP). In a first aspect, a method of such capabilities includes receiving a configuration message including at least a feedback mode configuration configuring a joint acknowledgement feedback mode, a TAG configuration for each serving cell, and any CORESET pool indices for the BWPs of the serving cells. A user equipment (UE) receives downlink transmissions and determines a timing advance for a PUCCH with a joint acknowledgement message using the last downlink control information (DCI) message received scheduling the downlink transmissions. Alternatively, a UE may use a predetermined timing advance. Other aspects and features are also claimed and described.
