A user equipment (UE) may use one or more antenna subarrays to perform a scheduling request (SR) operation with one or more corresponding transmission reception points (TRPs) while operating in a connected discontinuous reception mode. In some implementations, the UE may receive a configuration indicating a set of its antenna subarrays and a corresponding set of the TRPs with which to perform the SR operation. Based on this configuration, the UE may transmit an SR to the set of TRPs using the set of its antenna subarrays, receive an uplink grant from at least one TRP of the set of TRPs, and transmit uplink data to the at least one TRP. Additionally or alternatively, the UE may determine the sets of antenna elements and TRPs for the SR operation autonomously and transmit an indication of this determination when transmitting the SR. ## Claims ### Claim 1 A method for wireless communication at a user equipment (UE), comprising: receiving a configuration indicating a set of antenna subarrays of the UE, or a set of transmission reception points, or a combination thereof, for the UE to use to communicate while operating in a discontinuous reception mode;
