1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving, from a location server, a positioning reference signal (PRS) configuration for a downlink-and-uplink-based positioning session between the UE and the location server;
waiting, based on a determination that a sounding reference signal (SRS) configuration for the downlink-and-uplink-based positioning session has not been received from a serving base station of the UE, for reception of the SRS configuration from the serving base station until expiration of a timer; and
determining, based on the expiration of the timer, whether the SRS configuration was received.
