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: 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.

Abstract: A method includes causing, at a first user equipment (UE), transmission of at least one positioning reference signal (PRS) to a second UE via a sidelink (SL) communication based on first positioning assistance data. The transmission enables the second UE to determine positioning measurements from at least part of the at least one PRS.

Abstract: Disclosed are techniques for differentiating between licensed and unlicensed bands in a common portion of frequency spectrum to facilitate initial access in a fifth generation (5G) new radio (NR) wireless communication system having an NR node. The techniques include an NR generating and UE processing frequency configuration information indicating whether the common portion of frequency spectrum is allocated as a licensed band or an unlicensed band to enable a determination that the frequency spectrum is configured as the licensed band or unlicensed band and thereby facilitate initial access.

Abstract: To support layer 1 (L1) and layer 2 (L2) centric inter-cell mobility and inter-cell multi-TRP operation, a user equipment (UE) may need to measurement the downlink reference signals from neighbor cells. To obtain these measurements, a UE may perform layer 3 (L3) measurements for one or more neighboring cells, and provide an L3 measurement report to a network node. Candidate measurement neighboring cells for L1 measurements may be identified based on the L3 measurements.

Abstract: Provided is a method for a user equipment (UE). The UE obtains, from a network device, a first configuration information. The first configuration information indicates a first resource set for an aperiodic Sounding Reference Signal (AP-SRS). The first resource set for the AP-SRS includes a first list of slot offsets. The UE decodes a second configuration information from the network device. The second configuration information indicates a reference slot and a first slot offset of the first list of slot offsets. The UE generates the AP-SRS for transmission to the network device based on the reference slot and the first slot offset.
