1. A method for wireless communications, comprising:
receiving a first message for uplink power control that indicates a first set of configured downlink reference signal resources for a downlink reference signal, wherein the downlink reference signal comprises a path loss reference signal and the downlink reference signal is different from the received first message;
receiving a second message in response to the first set of downlink reference signal resources having been overwritten by a second set of downlink reference signal resources configured for the path loss reference signal, the second message indicating the second set of downlink reference signal resources for the downlink reference signal for updating the uplink power control, wherein the second message is different from the first message and the second message comprises a medium access control (MAC) control element associated with updating reference signal configurations; and
overwriting, in the uplink power control, the first set of downlink reference signal resources with the second set of downlink reference signal resources in response to receiving the second message.
