Abstract: Wireless communications systems and methods related to sidelink communications between user equipments (UEs). A method of wireless communication performed by a first UE comprises establishing a connection with a second UE on a first frequency channel; transmitting, via the first frequency channel, an indication of resources on a second frequency channel; transmitting, via the second frequency channel using the indicated resources, one or more signals sweeping a plurality of beam directions; receiving, via the first frequency channel or the second frequency channel in response to transmitting the one or more signals, an index associated with a preferred beam direction; and communicating with the second UE in the second frequency channel using the preferred beam direction.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink configuration that indicates a set of sidelink slots comprising a first subset of sidelink slots to be used for first transmissions of sidelink communications and a second subset of sidelink slots to be used for second transmissions of the sidelink communications. The UE may communicate based at least in part on the sidelink configuration. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a configuration for applying weighted averaging to layer 1 (L1) reference signal received power (RSRP) measurements. The UE may receive, from the network node, a plurality of reference signals during a period of time, the plurality of reference signals being quasi-co-located with each other. The UE may obtain weighted averaged L1 RSRP measurements associated with the plurality of reference signals based at least in part on the configuration, the weighted averaged L1 RSRP measurements being available as input to a machine learning (ML) model for beam prediction. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive multiple reference signals (RSs). The UE may measure the multiple RSs to generate measurements for the multiple RSs. The UE may encode the measurements using a machine learning model to generate codewords representing a quantized version of the measurements. The UE may transmit the codewords. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide techniques for using automatic gain control symbols to indicate a sidelink mini-slot. A method performed by a transmitting user equipment includes transmitting, during a first time portion of a symbol within a slot, a first beam associated with a first receiving user equipment. The first time portion of the symbol is configured to indicate that the first receiving user equipment will receive another transmission from the transmitting user equipment during a first mini-slot within the slot associated with the first time portion. The method may further include transmitting, during a second time portion of the symbol within the slot, a second beam associated with a second receiving user equipment. The second time portion of the symbol is configured to indicate that the second receiving user equipment will receive another transmission from the transmitting user equipment during a second mini-slot within the slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE and via a receive beam of the first UE, an inter-UE coordination (IUC) request, wherein the IUC request is based at least in part on a transmit beam of the second UE that is associated with an intended transmission of the second UE. The UE may transmit, to the second UE, IUC information that indicates preferred resources or non-preferred resources for the intended transmission, wherein the IUC information is based at least in part on a channel sensing by the first UE. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for determining and using channel ratio metrics for beamformed communication. A method that may be performed by a user equipment (UE) includes selecting a first beam of a plurality of beams for determining one or more channel ratio metrics, determining the one or more channel ratio metrics for the first beam, wherein determining the one or more channel ratio metrics is based, at least in part, on an angular separation between the first beam and one or more neighboring beams of the plurality of beams, and transmitting signaling via the first beam based on the one or more channel ratio metrics

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a sidelink coverage extension using repeated transmission. A first UE may transmit a multiple slot SCI in a first slot of a group of multiple slots for reserving resources for the group of multiple slots and transmitting one or more sidelink transmissions in the reserved resources. A second UE may receive the multiple slot SCI in the first slot of the group of multiple slots for receiving the one or more sidelink transmissions in the reserved resources for the group of multiple slots. In aspects, a base station may receive configuration parameters for the multiple slot SCI and configure one or more UEs with a multiple slot configuration, based on the configuration parameters, for transmitting/receiving the multiple slot SCI associated with the reserved resources in the group of multiple slots.
