Abstract: An apparatus, e.g., a UE, is disclosed. The apparatus may transmit, to a serving cell, UE capability information for performing L1/L2 measurements of at least one target RS received from a non-serving cell and reporting measurement information. The apparatus may receive, based on the transmitted UE capability information, a configuration including a TCI state scheduling the UE to receive the at least one target RS from the non-serving cell based on at least one source RS associated with the TCI state, and to perform the L1/L2 measurements of the at least one target RS. The number of RS reported in the measurement report may be based on at least one of a UE capability, an indication received from the serving cell, a pre-configuration, or an indication received from the serving cell in which the indication is within the UE capability.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for signaling whether to generate cross-link interference (CLI) measurement reports based on a single CLI measurement occasion or based on multiple CLI measurement occasions. A network entity may indicate whether to generate a CLI measurement report based on a single most recent CLI measurement occasion or based on CLI measured over a number of CLI measurement occasions. The measuring user equipment (UE) may generate a CLI report based on a single most recent CLI measurement occasion or based on a statistical CLI measurement based on respective CLI measurements for each respective CLI measurement occasion of the number of CLI measurement occasions depending on the indication. The network entity may also indicate to the aggressor UE to repeat transmission of sounding reference signals using the same transmit beam during the CLI measurement occasions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a candidate pattern from a set of patterns for reference signals used to track phase error. The UE may transmit an indication of the selected pattern to a base station and receive, from the base station at least in part in response to the transmitted indication of the selected pattern, an indication of a configuration for the reference signals used to track phase error, the configuration indicating a pattern of the set of patterns, a number of reference signal groups, and a number of samples per reference signal group. The UE may receive the reference signals used to track phase error according to the indicated configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A device may precode a phase tracking reference signal (PTRS) sequence by applying a single discrete Fourier transform (DFT) to the PTRS sequence. The device may map the DFT precoded PTRS sequence to a subset of resources of a set of resources, and may transmit a signal carrying the DFT precoded PTRS sequence. Additionally or alternatively, the device may receive a signal that includes a DFT precoded PTRS sequence, demap the DFT precoded PTRS sequence to a subset of resources of a set of resources, decode the DFT precoded PTRS by applying a single inverse DFT (IDFT) to the DFT precoded PTRS sequence, estimate a phase error based on the decoding, and apply a phase error correction to a set of additional symbols associated with the signal based on the estimated phase error.

Abstract: Methods, systems, and devices for wireless communications are described that provide for measurement and recovery of beamformed transmission beams in which an uplink beam and a downlink beam may be decoupled beams that use different beamforming parameters. In the event that a user equipment (UE) detects a failure of the downlink beam, an indication may be provided to a base station, and the downlink beam may be switched to correspond to the uplink beam. In the event that the UE detects a failure of the uplink beam the UE may identify a candidate beam and transmit a beam recovery message to the base station. The downlink beam may have an associated first set of reference signals, and the uplink beam may have an associated second set of reference signals, and beam failure may be determined based on the different sets of reference signals.
