Abstract: A user equipment (UE) may receive a measurement reporting capability request from a base station and further transmit, in response to the request, an indication of the UE's measurement reporting capability. The UE may further receive, signaling comprising a channel status information (CSI) request trigger from the base station. In response to receiving the CSI request trigger, the UE may transmit a measurement report to the base station, wherein the measurement report may comprise at least one received signal strength indicator (RSSI) measurement.

Abstract: Techniques discussed herein can facilitate the use of reference signals in active TCI switching. One example aspect is a user equipment (UE), comprising: a memory interface; and processing circuitry communicatively coupled to the memory interface and configured to: receive a physical downlink shared channel (PDSCH) message that includes an activation command indicating a target transmission configuration indicator (TCI) state; decode the activation command within a decoding period, where the decoding period is a time period allocated for the UE to decode the activation command; receive a TCI resource where the TCI resource is a reference signal; perform time and frequency tracking associated with the target TCI state according the TCI resource; and switch to the target TCI state after performing time and frequency tracking.

Abstract: A user equipment (UE) is served by a serving cell of a network and is configured to measure channel state information reference signals (CSI-RS) from a target cell. The UE receives, from the serving cell, a measurement configuration message indicating the UE is to measure CSI-RS from a target cell of the network, wherein the measurement configuration message does not include Synchronization Signal Block (SSB) information for the target cell but further comprises an indication of whether the target cell transmits SSBs. The UE determines, based on at least the measurement configuration message, a time and frequency resource on which the CSI-RS of the target cell are to be transmitted and measures the CSI-RS of the target cell.

Abstract: PUCCH carrier switching at a UE may include decoding an RRC configuration including a time-domain pattern indicating a reference cell and a target PUCCH cell for one or more PUCCH transmissions at a given point in time. The reference cell may include a reference cell slot numerology and the target PUCCH cell may include a target PUCCH cell slot numerology. A slot for PUCCH transmissions may be determined based on the reference cell slot numerology. The determined slot may be used for transmission of at least one of an SR, a CSI, and a HARQ-ACK. The determined slot of the reference cell may be mapped to a corresponding slot of the target PUCCH cell. A PUCCH resource may be determined for performing a PUCCH transmission using the corresponding slot of the target PUCCH cell. The PUCCH resource determination may be based on a PUCCH configuration of the target PUCCH cell.

Abstract: The present disclosure is related to indication of simultaneous RX beams capability and related measurement resource coordination. In an embodiment, a UE is configured to receive, from a base station, a measurement configuration comprising a measurement period for performing measurements on one or more carriers. The UE is further configured to assign measurement resources to the one or more carriers based on a simultaneous RX beams capability, wherein the measurement resources comprise searchers and RX beams during each measurement occasion. The UE is further configured to determine a measurement period scaling factor for the one or more carriers based on the assigned resources. With this capability, the UE can complete L1 and/or L3 measurements and transmit a measurement report to the base station earlier.
