Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a physical layer measurement on a non-serving cell of the UE. The UE may report a measurement value of the physical layer measurement to a serving cell of the UE based at least in part on the physical layer measurement satisfying a threshold. The UE may receive, based at least in part on reporting the physical layer measurement, a physical layer reference signal measurement configuration for the non-serving cell. The UE may transmit a measurement report based at least in part on the physical layer reference signal measurement configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A set of user equipments (UEs) may communicate with each other on communication links using data resources from a pool of shared resources. The UEs may be configured to multiplex control resources with data resources of a shared resource pool. In some cases, a UE may communicate, in control resources, control signaling to reserve data resources of a shared resource pool. After transmitting the request, the UE may communicate data in one or more data resources. The UE may communicate the data using transmission components while concurrently processing control signaling using other components.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for determining shared resources associated with one or more user equipments (UEs) for sidelink communications, including control resources and data resources. A first UE may determine a first set of control resources in a first frequency band corresponding to a first group of UEs including the first UE. The first UE may transmit a sidelink request to reserve a subset of data resources to a second UE in the first group of UEs. The first UE may monitor for one or more sidelink responses indicating a positive sidelink response to the sidelink request, a negative sidelink response to the sidelink request, or both. The first UE may determine, based on monitoring for the one or more sidelink responses, whether to transmit a sidelink confirmation indicating a reservation of the data resources to the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. A device may be configured to support multi-beam, or multi-panel operations, or both which may allow multiple sidelink transmissions to occur simultaneously. In some cases, flexible beam-management for the beamformed sidelink communications is implemented to manage the beams. A transmitting UE may indicate transmission beam information to the base station that the base station may use to schedule sidelink transmissions as part of a beam management procedure. The beam management procedure may allow a transmitting UE to update transmission beam information based on the mobility of the sidelink UEs and other environmental factors. In some cases, beam management includes a beam training procedure that may be implemented to refine the sidelink beams, where support for multi-panel and multi-beam operation may allow for multiple beams to be trained simultaneously.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a configured grant that indicates time-frequency resources for a user equipment (UE) to use to transmit sidelink or uplink messages in a wireless communications system. To reduce the amount of low priority traffic that may interfere with higher priority traffic, the base station may configure a threshold probability to allow high priority sidelink transmissions and to cancel low priority transmissions. The base station may transmit a cancellation indication that includes a priority indication instructing the UE to cancel transmissions having a priority less than a priority threshold during the allocated time-frequency resources. Based on transmitting the cancellation indication, the base station may cancel transmissions that have low priority, and the UE may determine whether to transmit (or to refrain from transmitting) one or more messages based on the priority of the message.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be scheduled for communicating a first message over a first communication link with a base station and a second message over second communication link with a second UE. The first UE may select to communicate using the first communication link or the second communication link based on one or more prioritization rules that may involve the priority of the first message and the second message. The first UE may identify a mapping between the priority of the first message and the priority of the second message that may enable a comparison of the priorities of the first message and the second message. The first UE may select to communicate using the communication link of the message associated with the higher priority.

Abstract: Method and apparatus are provided for reporting and receiving actual UL transmission power. In accordance with some implementation, a UE may send a first indication of power headroom to a base station. The UE may receive one or more resources allocation for a UL transmission. The UE then may determine actual transmission power to be used in the UL transmission. Upon determination, the UE may transmit the UL transmission and send an indication of the actual transmission power to the base station. The base station, in response to receiving an indication of actual transmission power of the first UL transmission, may adjust an estimate of the link quality based on the receive indication of actual transmission power.

Abstract: Aspects described herein relate to determining and/or scheduling resources for devices in view of cross-channel interference measured between the devices. In an aspect, a first user equipment (UE) can determine a signal measurement of a signal transmitted by a second UE in a first channel, determine, based at least in part on the signal measurement, a cross-channel interference parameter of interference experienced by the first UE, and transmit, to a serving base station that serves the first UE, an indication of the cross-channel interference parameter. In another aspect, a base station can determine a cross-channel interference parameter of interference experienced by a first UE in at least a first channel, based on a signal transmitted by a second UE in a second channel, and can schedule communications for the first UE based at least in part on the cross-channel interference parameter.
