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: Techniques, systems, and devices for wireless communications are described. A user equipment (UE) may be in communication with a first and second transmitting device (e.g., by sidelink communication links). The UE may receive, from the first transmitting device, a first reference signal on a first set of resources. The UE may additionally receive, from the second transmitting device, a second reference signal on a second set of resources that overlap in the time domain with the first set of resources. In some cases, the first and second set of resources may additionally overlap in the frequency domain. The UE may determine synchronization information for time tracking or frequency tracking of sidelink communications with the first and second transmitting devices based on the first and second reference signals. The UE may communicate with the first and second transmitting devices based on the synchronization information for time tracking or frequency tracking.

Abstract: Discussed is wireless communication that includes beam failure detection and recovery for high priority or broadcast CORESETs performed in wireless communication systems to effectuate an overall improvement in wireless communication. In some aspects, a mobile device may monitor one or more first reference signals associated with wireless communication performed using one or more first reception beams. The mobile device may also monitor one or more second reference signals associated with wireless communication performed using one or more second reception beams. The mobile device may detect a failure in wireless communication performed using the one or more first reception beams based, at least in part, on the monitoring of the one or more first reference signals. The mobile device may also initiate a beam failure recovery procedure for the one or more first reception beams upon detecting the failure in wireless communication performed using the one or more first reception beams.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that configures a channel measurement resource and an interference measurement resource within a same time interval. The UE may transmit a measurement report that indicates a signal to interference plus noise ratio (SINR) measurement that is generated based on measuring the channel measurement resource and the interference measurement resource. In some cases, the UE may receive a quasi co-location (QCL) relationship indicator that indicates a QCL relationship for the interference measurement resource or the channel measurement resource. The UE may measure the channel measurement resource and the interference measurement resource in accordance with the QCL relationship.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indicator of a feedback window that is offset relative to a beginning transmission time interval (TTI) of a set of consecutive TTIs. The consecutive TTIs may include a set of aggregated slots or may correspond to a multi-TTI grant. The feedback window may include multiple control channel occasions interspersed within a duration of the set of consecutive TTIs. The UE may receive a transport block within a first TTI of the set of consecutive TTIs and transmit, within a control channel, feedback to indicate whether the transport block was successfully received.
