Abstract: A base station may transmit a report mask indicating a transmission of a layer 1 reference signal received power (L1-RSRP) report limited to a time period when a discontinuous reception (DRX) timer is running for a wireless device. The base station may receive the L1-RSRP from the wireless device at a first time, in response to the DRX timer running at a predefined time period before the first time. The received L1-RSRP report may include an L1-RSRP value and a reference signal index associated with the L1-RSRP value. At second time, the base station may skip a reception of a configured L1-RSRP report transmission from the wireless device in response to the DRX timer not running at the predefined time period before the second time and the report mask.

Abstract: Methods, systems, and devices for wireless communication are described. In aspects of the present disclosure, a user equipment (UE) may report metrics (e.g., received signal power, beam identifier) about synchronization signal (SS) beams using the same (e.g., or a similar) framework that is used for channel state information reference signal (CSI-RS) reporting. Because SSs are intended to be broadcast across a wide coverage area in a beamformed manner, the SSs represent a promising complement to existing beam management techniques. Accordingly, beam management may be achieved at least in part based on reporting one or more metrics of beamformed SSs through a channel feedback framework.
