Abstract: Apparatus, methods, and computer-readable media for facilitating scrambling of sidelink control information for sidelink communication are disclosed herein. The scrambling of the SCI may include scrambling CRC, scrambling information bits, and/or scrambling channel bits. An example method for wireless communication at a user equipment UE includes scrambling at least a portion of SCI. The example method also includes transmitting the SCI carrying control information for a sidelink transmission. In another aspect, an example method for wireless communication at a UE includes receiving SCI having scrambled bits. The example method also includes decoding the SCI based on information known to the UE.

Abstract: Method and apparatus to determine a sidelink beam and associated power control parameter for sidelink communication. The apparatus initiates a beam pairing with a second UE, the first UE being a transmitting UE and the second UE being a receiving UE. The apparatus identifies a sidelink beam from a plurality of sidelink beams and at least one power control parameter for sidelink communication with the second UE. Different sidelink beams use different power control parameters. The apparatus communicates with the second UE via a selected sidelink beam and the at least one power control parameter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node of a wireless network may transmit, by a first distributed unit (DU) of the first node to a central unit (CU), a second DU of another node in the wireless network, a user equipment in the wireless network, or a child node of the first node, an indication of a suggested resource pattern for the DU.

Abstract: The present disclosure provides for beam selection by a mobile device based on a sensor state of the mobile in order to mitigate hand blockage. The mobile device detects, during operation of the mobile device, a sensor state caused by a hand of an operator on the mobile device. The mobile device selects for communication, while operating in the sensor state, a refined beam set corresponding to the sensor state based on reference signals. The mobile device trains a machine learning model based on a set of training data including pairs of the sensor state and the refined beam set to select a first set of beam weights from a second set of beam weights based on a detected sensor state. The mobile device selects for communication a hand blockage state including the first set of beam weights for a current detected sensor state based on the machine learning model.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a channel state information (CSI) reporting configuration for a CSI report, wherein the CSI reporting configuration indicates that the CSI report is to include a layer 1 signal to interference plus noise ratio (L1-SINR). The UE may determine a number of CSI processing units (CPUs) occupied for processing of the CSI report that is to include the L1-SINR. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE). For example, the UE receives a first indication indicating a same quasi co-location (QCL) mapping for multiple receive beams corresponding to a group of transmit and receive beam pairs from a network entity. Transmit and receive beam pairs are different from each other and grouping of the transmit and receive beam pairs is based on a distance between the UE and the network entity. The UE selects one of the multiple receive beams corresponding to the group of transmit and receive beam pairs, based on the distance between the UE and the network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a first set of resources for an access link communication between the first UE and a base station. The UE may identify a second set of resources for a sidelink communication between the first UE and a second UE. The UE may identify a scheduling conflict between the first set of resources for the access link communication and the second set of resources for the sidelink communication. The UE may drop at least a portion of the first set of resources for the access link communication or the second set of resources for the sidelink communication based at least in part on the identification of the scheduling conflict and a prioritization rule. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a buffer status report associated with a one-to-many sidelink communication. The UE may receive, from the base station, one or more downlink control information (DCI) messages scheduling one or more sidelink communications, associated with one or more spatial transmission directions, for the one-to-many sidelink communication, wherein the one or more DCI messages allocate resources for each of the one or more spatial transmission directions. The UE may transmit, using the resources and in the one or more spatial transmission directions, the one or more sidelink communications for the one-to-many sidelink communication. Numerous other aspects are described.
