Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure, using one or more beams included in a first beam group associated with the UE, a channel occupancy ratio (CR) for the first beam group. The UE may perform an action if the CR for the first beam group does not satisfy a CR limit associated with the first beam group. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. In a system with high reliability and low latency targets, base station control can be dynamically configured. In some systems, a semi-static split with a greater duration for communications between a controller and one or more associated sensor/actuators than a duration for communications between the controller and base station can be used. In some embodiments, an interrupt can be used to allow for base station control.

Abstract: Apparatus, methods, and computer-readable media for facilitating techniques for phase continuity of sidelink DMRS bundling are disclosed herein. An example method for wireless communication at a first UE includes receiving a first sidelink transmission including at least a first DMRS. The example method also includes receiving a second sidelink transmission, the first sidelink transmission and the second sidelink transmission together including at least the first DMRS and a second DMRS. The example method also includes receiving, from a second UE, an indication of a bundling relationship between the first sidelink transmission and the second sidelink transmission, the bundling relationship including at least one of strong bundling, weak bundling, or no bundling. The example method also includes performing channel estimation for a channel associated with the first sidelink transmission and the second sidelink transmission based at least in part on the bundling relationship.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may receive, for communications with one or more of a base station or another wireless device, information identifying that an uplink transmission on a sidelink and a downlink transmission on a sidelink are to precede an uplink transmission on an access link and a downlink transmission on an access link. The wireless device may communicate, with the one or more of the base station or the other wireless device, based at least in part on the information identifying that the uplink transmission on the sidelink and the downlink transmission on the sidelink are to precede the uplink transmission on the access link and the downlink transmission on the access link. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for group semi-persistent scheduling (SPS) for path diversity. A method that may be performed by a node includes configuring one or more groups of user equipments (UEs) with one or more SPS resources. The node sends a downlink control information (DCI) to activate one of the SPS resources for one of the groups of UEs and transmits data to the group of UEs using the activated SPS resource. A first UE may receive data from the node using the activated SPS resource and retransmit the data to the second UE. The first helping UE and the second targeted UE may be identified based on the higher layer configuration with the SPS resources, based on information in the DCI, and/or based on information sent with the data.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a grant to a first user equipment (UE) that indicates a resource allocation for a sidelink communication, either from the first UE to a second UE or from the second UE to the first UE. The grant may include a destination identifier associated with the sidelink communication, as well as a mapping between the resource allocation and the destination identifier. The destination identifier may be based on information in an indication received from the first UE. In some examples, the base station may configure a default receiver UE for transmissions from the first UE, and the base station may identify a receiver UE in the grant if the intended receiver UE is different than the default receiver UE.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a base station associated with the first UE and a second UE, a downlink control information activating a set of configured grant resources for transmissions from the second UE to the first UE. The UE may transmit, according to the downlink control information, a feedback message to the base station confirming receipt of the downlink control information.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may utilize opportunistic cooperative relaying to support exchanging packets between UEs without establishing or maintaining beamforming alignment between the UEs. Specifically, a source UE may invite nearby UEs (e.g., helper UEs) that receive a sidelink transmission (e.g., a packet meant for a different destination UE) to perform a single frequency network (SFN)-type transmission to opportunistically relay the packet to the destination UE. The helper UEs may receive, decode, and transmit the sidelink signaling from the source UE without establishing or configuring a relay agreement with the source UE. The destination UE may receive the sidelink signaling via cascading, SFN-type transmissions by one or more helper UEs. The destination UE may respond to the sidelink signaling with feedback information via one or more helper UEs or directly to the source UE.

Abstract: Methods, systems, and devices for wireless communications are described. Autonomous transmissions between a user equipment (UE) and a base station may be configured that include at least one of a modulation and coding scheme (MCS) or resources for the transmissions. In some cases, a trigger may be detected that changes the MCS or resources to be used for the autonomous transmissions. The trigger may include the presence or absence of retransmissions or the value of a channel measurement falling below or exceeding a threshold value. Accordingly, the base station and UE may adjust the MCS or resources to be used for the autonomous transmissions based on detecting the trigger and then communicate using the adjusted MCS or resources. In some cases, the configuration for the autonomous transmissions may be signaled via a medium access control (MAC) control element (CE).

Abstract: Certain aspects of the present disclosure provide techniques for enhanced sidelink (SL) control signaling with time division duplexing (TDD). A method that may be performed by a first user equipment (UE) may include receiving a TDD configuration indicating resources of a resource pool available for SL transmissions between the first UE and at least a second UE and exchanging SL communications with the second UE in one or more slots or symbols based, at least in part, on the TDD configuration. The TDD configuration may define one or more of the slots or symbols as flexible slots or symbols that may be configured as downlink (DL) or uplink (UL) slots or symbols. The TDD configuration may also identify one or more of the slots or symbols as UL slots or symbols and one or more slots or symbols as DL slots or symbols.
