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, a first message that indicates a sidelink bandwidth part (BWP) switch, for the second UE, to a first sidelink BWP, where the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The first UE may transmit, to the second UE, a second message that confirms the sidelink BWP switch for the second UE. The first UE may receive, from the second UE, a third message that activates the sidelink BWP switch, for the second UE, to the first sidelink BWP. 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 information that indicates one or more parameters that correspond to one or more initial active bandwidth parts (BWPs), each initial active BWP being smaller than a full available BWP. The UE may select an initial active BWP from the one or more initial active BWPs. The UE may transmit a random access channel message based at least in part on a first parameter, of the one or more parameters, that corresponds to the selected initial active BWP. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a PRS sequence is determined based in part on a sidelink zone where a transmitting UE is located. A receiving UE may perform a blind search based on PRS sequence(s) associated with its own sidelink zone and/or neighboring sidelink zones. In other aspects, measurement reports may be conveyed to a position estimation entity with positioning measurements being associated with respective PRS sequences, which can then be correlated to the respective transmitting UEs at the position estimation entity so as to facilitate position estimation of a target UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) switch between carriers of a group of a carriers during uplink communications in accordance with a mapping. For example, the UE may report its capability to a base station for switching between carriers of the group, where the group includes a supplementary uplink (SUL) carrier and two or more normal uplink (NUL) carriers that are each associated with a different radio frequency band. The base station may indicate for the UE to switch to a subset of carriers of the group corresponding to a combination of radio frequency bands for transmission of an uplink message. The UE may switch to at least one carrier of the subset of carriers in accordance with a mapping that is based on the reported capability and may transmit the uplink message on the at least one carrier.

Abstract: Disclosed are techniques for allocating resources for environment sensing. In an aspect, a base station transmits a first radar reference signal (RRS) on a first set of resources comprising first time resources, first frequency resources, first spatial resources, or any combination thereof, wherein the first set of resources is selected to enable a first user equipment (UE) to perform a first type of environment sensing, and transmits a second RRS on a second set of resources comprising second time resources, second frequency resources, second spatial resources, or any combination thereof, wherein the second set of resources is selected to enable a second UE to perform a second type of environment sensing, wherein the second set of resources is different from the first set of resources, and wherein the second type of environment sensing is different from the first type of environment sensing.

Abstract: Mechanisms for cross-carrier scheduling from a first cell to a second cell in a wireless networking scheme are provided. In one aspect, a method includes receiving, from a base station (BS), a first configuration for scheduling in a first cell having a first subcarrier spacing (SCS), wherein the first configuration is associated with a first search space in the first cell. The method further includes receiving, from the BS, a second configuration for scheduling in the first cell, wherein the second configuration is associated with a second search space in a second cell, and wherein the second cell is associated with a different second SCS. The method further includes determining a number of blind detections (BDs) based on at least one of the first SCS or the second SCS, and monitoring, based on the number of BDs, for downlink control information (DCI) in the first and second search spaces.

Abstract: Wireless communications systems and methods related to communicating ACK/NACK feedbacks for multi-user and unicast physical down-link shared channel (PDSCH) communications are provided. A UE may receive a multi-user PDSCH communication including a first transport block (TB) for the UE and may receive a unicast PDSCH communication including a second TB for the UE. The UE may determine a hybrid automatic repeat request (HARQ) codebook for the first TB associated with the multi-user PDSCH communication and the second TB associated with the unicast PDSCH communication. The UE may transmit a first acknowledgement/negative-acknowledgment (ACK/NACK) feedback for the first TB and a second ACK/NACK feedback for the second TB based on the determined HARQ codebook.

Abstract: A method of cross validating a positioning reference signal includes: measuring, at a first UE, a first PRS resource to determine a first PRS measurement; receiving, from a second UE via sidelink communication, a second PRS measurement of a second PRS resource; and determining whether at least one of the first PRS measurement or the second PRS measurement is unreliable based on a relationship of the first PRS measurement to the second PRS measurement.
