Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to cell recovery techniques. One example method generally includes receiving, on a first cell, an indication that one or more channel measurements are to be reported for a second cell for which beam failure is detected; transmitting a first message triggering reporting of at least one preferred beam for communicating on the second cell, the first cell being different from the second cell, wherein the first message is transmitted in response to the indication that the one or more channel measurements are to be reported; receiving a report indicating the at least one preferred beam; and configuring a transmission configuration state in accordance with the at least one preferred beam for communicating on the second cell.

Abstract: Certain aspects of the present disclosure relate to quasi co-location assumptions for aperiodic channel state information (CSI) reference signals (RS) in communications systems operating according to NR techniques. An exemplary method that may be performed by a UE includes determining a quasi-co-location (QCL) relationship of an aperiodic channel state information (CSI) reference signal (CSI-RS) to a physical channel and processing the aperiodic CST-RS according to the determined QCL relationship.

Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration enhancements. A method generally receiving pre-configuration information for one or more reference signal transmissions, performing, at a first time during an ON duration of a discontinuous reception (DRX) cycle, measurements on one or more reference signals based, at least in part, on the pre-configuration information, determining if, at a second time during the ON duration after the first time, a trigger frame associated with the one or more reference signal transmissions has been received, and transmitting a measurement report corresponding to the measurements if a trigger frame has been received.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit receive point (TRP), a downlink control information (DCI) communication, the UE being included in a multi-TRP configuration with the first TRP and a second TRP. The UE may determine information unique to the first TRP. The information unique to the first TRP may be at least one of associated with the DCI communication or included in the DCI communication. The UE may generate a downlink scrambling sequence initialization code, associated with the first TRP, based at least in part on the information unique to the first TRP. The UE may generate a downlink scrambling sequence, associated with the first TRP, based at least in part on the downlink scrambling sequence initialization code associated with the first TRP. Numerous other aspects are provided.

Abstract: In multi-beam communication, the UE may assist in the scheduling of beams utilized during the multi-beam communication by improving the manner in which the quality of the beam is reported to the network. The apparatus may measure a signal received from a base station on at least one beam. The apparatus may detect a triggering event for providing CSI for the at least one beam. The apparatus may transmit an uplink transmission comprising a CSI report in response to detecting the triggering event. The apparatus may receive an uplink request from a UE for providing CSI for at least one beam. The apparatus may transmit an indication scheduling a CSI report in response to the uplink request. The apparatus may receive an uplink transmission from the UE comprising the CSI report for the at least one beam.

Abstract: In order to overcome problems that a UE may face in determining a default beam for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL assumptions, UL resources, and/or spatial relationships are selected for a COT. A UE receives, from a base station, an indication corresponding to a COT. The indication is for at least one of a set of CORESETs, a set of QCL assumptions, a set of UL resources, or a set of spatial relations for determining a default beam. The UE determines the default beam from the base station for use during the COT based on the indication. The UE transmits or receives a transmission using the default beam.
