Abstract: Methods, systems, and devices for wireless communications are described. Sidelink UEs may be configured with a synchronization reference signal that may be used by the UEs to synchronize time and frequency resources. A first and second UE may perform a beam sweeping procedure to identify transmit and receive beams to use for communications between the UEs. A synchronization reference signal procedure may be initiated and the first UE may receive a sidelink synchronization reference signal from the second UE using the established receive beam. The UEs may align time and frequency resources for communications between the UEs and the UEs may communicate via the sidelink channel based on the time synchronization, frequency synchronization, or both, determined using the sidelink synchronization signal. In some cases, a sidelink UE may receive multiple synchronization reference signals from multiple sidelink UEs simultaneously, where each synchronization reference signal may include a UE identifier.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing and reporting reference signal received power (RSRP) measurements. In particular, the techniques described herein may allow a user equipment (UE) to efficiently identify reference signals on which to perform RSRP measurements (e.g., based on signaling from a base station), identify when to report RSRP measurements (e.g., aperiodically, periodically, or semi-persistently), and identify a channel on which to report RSRP measurements (e.g., a sidelink channel or an uplink channel). In addition, the techniques described herein may also allow a UE to efficiently identify open loop parameters to use to determine an appropriate transmit power for transmitting to another UE over a sidelink.

Abstract: A synchronization signal block (SSB) transmitted by a neighbor base station may interfere with a physical downlink shared channel (PDSCH) transmitted by a serving base station. A user equipment (UE) that receives both the SSB and PDSCH may mitigate the interference to improve an error rate of decoding the PDSCH. The UE may receive a first SSB including a first broadcast channel (BCH) from a second base station other than a serving base station. The UE may decode the first SSB. The UE may determine, based on the first SSB and the first BCH, that the PDSCH scheduled by the serving base station will overlap with a second SSB from the second base station. The UE may estimate a channel of the second SSB based on the decoded first SSB. The UE may remove a reconstructed second SSB from the PDSCH. The UE may decode the PDSCH.

Abstract: A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for “dropping” CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.

Abstract: A user equipment terminal (UE) in a wireless network calculates a measurement period for measuring the signal-to-interference-plus-noise ratio (SINR) for a serving cell within a frequency range. The calculation is based on a channel measurement resource (CMR) and an interference measurement resource (IMR). The calculation includes evaluation of a sharing factor P, which is a maximum of PCMR of the CMR and PIMR of the IMR. The PCMR and the PIMR are evaluated, at least in part, based on periodicity of the CMR and the IMR in relation to other periodic measurements performed by the UE. The UE performs a channel measurement and an interference measurement using the CMR and the IMR, respectively, over the measurement period. The UE calculates the SINR based on the channel measurement and the interference measurement; and transmits an SINR measurement report indicating the calculated SINR to a base station.
