Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, in a first slot within a channel occupancy time (COT), a first communication; determine whether one or more transmission criteria are satisfied for transmission of a second communication in a second slot within the COT; and selectively transmit the second communication in the second slot within the COT based at least in part on a result of determining whether the one or more transmission criteria are satisfied. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a carrier associated with a primary cell (PCell), the carrier configured with a first control resource set (CORESET) pool index value and a second CORESET pool index value. The UE may receive an indication of a set of candidate beams available for a beam failure recovery (BFR) procedure, the set of candidate beams comprising a first subset of candidate beams associated with the first CORESET pool index value and a second subset of candidate beams associated with the second CORESET pool index value. The UE may detect a beam failure on the carrier on an active beam of the primary cell that is associated with the first CORESET pool index value or the second CORESET pool index value. The UE may select a new candidate beam from the set of candidate beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a first uplink transmission using a first transmit power that is based at least in part on: a first power level associated with the first uplink transmission, and a power scaling factor based at least in part on a power offset. The UE may transmit, to the network node, a second uplink transmission, at least partially overlapping in time with the first uplink transmission, using a second transmit power that is based at least in part on: a second power level associated with the second uplink transmission, a maximum available transmit power, and the first transmit power. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a first message to indicate a sidelink bandwidth part (BWP) switch, for the first UE, to a first sidelink BWP, wherein the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The UE may receive, from the second UE, a second message that confirms the sidelink BWP switch for the first UE. The UE may transmit, to the second UE, a third message to activate the sidelink BWP switch, for the first UE, to the first sidelink BWP, based at least in part on receiving the second message that confirms the sidelink BWP switch. Numerous other aspects are described.

Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE associated with a sidelink connection with the first UE, assistance information indicating at least part of a first discontinuous reception (DRX) configuration for a radio access link between the first UE and a base station. The UE may receive at least part of a sidelink DRX configuration for the sidelink connection, wherein an on duration of the sidelink DRX configuration is not aligned with an on duration of the first DRX configuration. The UE may transmit information indicating at least part of the sidelink DRX configuration. The UE may receive, from the base station, a second DRX configuration for the radio access link. The UE may communicate in accordance with the sidelink DRX configuration or the second DRX configuration. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity configures a sidelink anchor group with sidelink anchor(s), to which respective sidelink PRS pre-configuration(s) are sent. A UE transmits a request to schedule an on-demand sidelink PRS position estimation session of the UE. The position estimation entity provides the UE with assistance data associated with the sidelink anchor group for the on-demand sidelink PRS position estimation session. The UE sends the sidelink anchor group a sidelink PRS trigger to perform a sidelink PRS exchange with some or all of the sidelink anchor group in accordance with the respective sidelink PRS pre-configuration(s).
