Abstract: Methods, systems, and devices for wireless communications are described. A served user equipment (UE) may receive a first configuration signal configuring the served UE with first transmission beam resources and second transmission beam resources for the served UE to use for beam management over a sidelink channel. The served UE may identify, based at least in part on the first configuration signal, a pattern for performing beam management using the first transmission beam resources and the second transmission beam resources. The served UE may perform the beam management over the sidelink channel in accordance with the pattern using the first transmission beam resources and the second transmission beam resources.

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: 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.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may transmit a sidelink request to a second UE. The sidelink request may indicate a set or a segment of the data resources. A second UE may transmit a positive sidelink response indicating that the set or the segment of resources is available for reservation, or may refrain from transmitting a positive sidelink response if the set or the segment of the data resources is unavailable for reservation. A third UE may transmit a negative sidelink response indicating that the set or the segment of the data resources is unavailable for reservation, or may refrain from transmitting a negative sidelink response if the set or the segment of the data resources is available for reservation. If the requested data resources are available, then the first UE may transmit a sidelink confirmation reserving the requested data resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a capability message indicating a parameter configuration for each phase error process of a set of phase error processes of the first UE. The first UE may transmit, to a second UE, a phase error process indicator to indicate that the first UE is using a first phase error process of the set of phase error processes to generate a sidelink transmission in accordance with the parameter configuration for the first phase error process. The second UE may monitor, via a sidelink channel, for the sidelink transmission based on frequency tracking, phase tracking, time tracking, or any combination thereof being performed in accordance with the parameter configuration for the first phase error process. The first UE may transmit, via the sidelink channel, the sidelink transmission to the second UE.

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

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may receive, from a base station, a sidelink resource configuration indicating physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) occasions on which to monitor a PSCCH for a grant from a second UE. The first UE may determine an active time for monitoring the PSCCH based on a discontinuous reception (DRX) mode for a link with the base station, the DRX mode including an active state in which a physical downlink control channel (PDCCH) is monitored and an inactive state in which the PDCCH is not monitored. The first UE may monitor the PSCCH during one or more of the PSCCH/PSSCH occasions that coincide with the active time.

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.
