Abstract: Methods, systems, and devices for wireless communications are described. A base station (e.g., a central unit (CU) function of the base station) may select, from a set of distributed units (DUs) associated with the CU, a DU of an integrated access and backhaul (IAB) node to control sidelink communications for a user equipment (UE). The base station may determine a configuration of sidelink parameters for the sidelink communications with the UE, the sidelink parameters comprising an identification of the selected DU. The base station may transmit, to the TAB node performing sidelink communications with the UE, an indication of the configuration of sidelink parameters for the sidelink communications.

Abstract: Aspects are provided which allow AGC symbols to be applied for identifying or indicating target Rx UEs of sidelink communications from Tx UEs. A Tx UE transmits an AGC signal to a Rx UE in a RB associated with the Rx UE. The Rx UE receives the AGC signal from the Tx UE. The Tx UE transmits sidelink data to the Rx UE after the AGC signal. The Rx UE decodes sidelink data from the Tx UE in response to the AGC signal being received in a RB associated with the Rx UE. The Rx UE refrains from decoding the sidelink data from the Tx UE in response to the AGC signal being received in a different RB than the RB associated with the Rx UE. In this way, Rx UEs may save monitoring and processing power and time in receiving and decoding sidelink communications.

Abstract: Disclosed are techniques for wireless communication. In an aspect, an integrated access and backhaul (IAB) node sets a downlink transmission timing of the IAB node relative to a downlink reception timing of the IAB node based on a first set of values for a set of timing parameters, receives, from a parent IAB node of the IAB node, a second set of values for the set of timing parameters, and transmits, to a positioning entity, a report indicating a change from the first set of values to the second set of values, a new downlink transmission timing based on the second set of values, or a change in downlink transmission timing.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, via first frequency ranges and first time periods, a plurality of sidelink control blocks that each indicate a sidelink positioning reference signal burst pattern for one or more sidelink UEs. The UE may receive, within a second frequency range and during a second time period, a plurality of multiplexed sidelink positioning reference signals from the one or more sidelink UEs in accordance with the sidelink positioning reference signal burst patterns. The UE may determine a position of the UE based at least in part on the receiving of the plurality of multiplexed sidelink positioning reference signals.

Abstract: A first UE may receive SCI including one or more resource reservations of a second UE based on an indication from a MAC layer to a PHY layer to monitor for the SCI including the one or more resource reservations of the second UE. The indication from the MAC layer to the PHY layer may trigger at least one of a sensing beam, a TCI state, or a spatial relation. The at least one of the sensing beam, the TCI state, or the spatial relation may be associated with monitoring for the SCI including the one or more resource reservations of the second UE. The first UE may transmit a beam to a target UE on one or more resources that are selected based on the one or more resource reservations of the second UE.

Abstract: Techniques for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) scheduling sidelink transmissions in one or more sets of multiple transmission time intervals (TTIs) over a shared spectrum. The UE may perform a listen-before-talk (LBT) for one or more of the TTIs in the one or more sets of multiple TTIs, and the UE may transmit, to a base station, an indication of results of the LBT performed for the one or more TTIs. Because the UE may provide the results of the LBT to the base station, the base station may be able to schedule sidelink transmissions from the UE based on the results of the LBT. As such, the UE may experience increased throughput in sidelink communications since the scheduling at the base station may be improved.

Abstract: Aspects relate to grouping sidelink carriers in a wireless communication network. A first wireless communication device, such as a user equipment (UE), may communicate with a base station on a cellular link utilizing a first set of first component carriers (CCs) in a particular frequency band. The UE may identify one or more first carrier groupings for the first set of first CCs with the base station. The UE may communicate with a second wireless communication device, such as a second UE, on a sidelink utilizing a second set of CCs within the same frequency band. The first UE may map at least one second CC to a respective corresponding first CC and apply the one more carrier groupings to the second set of CCs to generate one or more second carrier groupings based on the mapping.

Abstract: Apparatus, methods, and computer-readable media for sidelink multiple transmission reception points (TRPs) relaying are disclosed herein. An example method for wireless communication at a base station includes transmitting communication for a target user equipment (UE) to multiple TRPs for relaying the communication to the target UE over a sidelink. The method may further include configuring, for one or more of the target UE or at least one of the multiple TRPs, a first transmission configuration indicator (TCI) state for a physical sidelink control channel (PSCCH) between the UE and the at least one of the multiple TRPs.
