Abstract: Wireless communications systems and methods are provided. A method of wireless communication may include performing a first listen-before-talk (LBT) procedure associated with a channel, wherein a channel occupancy time (COT) for the channel is acquired based on the first LBT being successful, communicating a first communication signal in a first link direction during the COT, switching from the first link direction to a second link direction different from the first link direction, and communicating after the switching, a second communication signal in the second link direction without performing a second LBT.

Abstract: Wireless communication devices, systems, and methods related to mechanisms to aid a user equipment (UE) in determining the channel access priority (CAPC) to use for a data radio bearer (DRB) on sidelink that includes multiple quality of service (QOS) flows for a transmission. The UE may receive an indication from a base station (BS) regarding what CAPC to use, or it may itself determine the CAPC based on a rule. The UE may map the plurality of QoS flows to the DRB and transmit the QoS flows using the DRB and the selected CAPC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically relate to sidelink communications and physical sidelink feedback channel (PSFCH) transmissions. A channel occupancy time (COT) initiating user equipment (UE) may obtain PSFCH information that indicates a plurality of PSFCH transmission occasions. The COT initiating UE may transmit a sidelink communication to a responding UE. In some aspects, the COT initiating UE may receive, from the responding UE, hybrid automatic repeat request (HARQ) feedback in each PSFCH transmission occasion of the plurality of PSFCH transmission occasions. In some other aspects, the COT initiating UE may receive, from the responding UE, HARQ feedback in at least the first PSFCH transmission occasion of the plurality of PSFCH transmission occasions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a first cell, a physical downlink control channel (PDCCH) order, wherein the PDCCH order includes an indication identifying a second cell to which the PDCCH order applies, wherein the second cell is different from the first cell, and wherein the PDCCH order triggers a random access procedure associated with the second cell. The UE may perform the random access procedure associated with the second cell based at least in part on the PDCCH order. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sidelink assistance for communication between a user equipment (UE) and a network entity. In some aspects, a set of UEs and a network entity may support one or more signaling mechanisms according to which at least one UE is able to assist other UEs in receiving or obtaining information to use for communication with the network entity. For example, a first UE may receive assistance information from a second UE and may use the received assistance information for communication between the first CE and the network entity or may otherwise operate in accordance with the received assistance information. Such assistance information may include an indication of a system information change, a public warning signal (PWS) notification, one or more signal strength measurements, or uplink transmission information.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device (e.g., a sidelink user equipment (UE), such as a first UE) may receive sidelink communications from a second UE via a sidelink channel. The receiving device may transmit a feedback message to the second UE via a sidelink feedback channel using a first resource configuration, the feedback message based at least in part on the sidelink communications. The receiving device may identify a second resource configuration of the sidelink feedback channel associated with sidelink communications via the sidelink feedback channel. The receiving device may perform the sidelink communications with the second UE via the sidelink feedback channel using the second resource configuration of the sidelink feedback channel.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for independent scheduling by a first transmission and reception point (TRP) and a second TRP for a user equipment (UE) operable in a multiple TRP (mTRP) mode. A semi-static time division duplexing (TDD) pattern may indicate a set of downlink symbols, a set of uplink symbols and a set of flexible symbols. A portion of the flexible symbols may be dedicated for communications with the first TRP, and the second TRP may not use the portion of the flexible symbols dedicated for communications with the first TRP. The first UE may operate in the mTRP mode in the semi-static downlink symbols or uplink symbols and operate in a single TRP mode in the portion of the flexible symbols dedicated for communications with the first TRP.
