Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing timing for inter-user equipment (UE) coordination to prevent or minimize interference or collisions between sidelink transmissions. A first UE may determine a time window in which to select sidelink resources for an inter-UE coordination message based on a minimum time configured for selecting the sidelink resources. The minimum time configured for selecting the sidelink resources for the inter-UE coordination message may be different from a minimum time configured for selecting sidelink resources for other sidelink messages. The first UE may then select the sidelink resources in the time window for the inter-UE coordination message and transmit the inter-UE coordination message on the selected sidelink resources to the second UE over a sidelink.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control signaling indicating a co-channel configuration. The co-channel configuration may indicate a set of sidelink parameters for a co-channel operation associated with dynamically utilizing sidelink radio frequency resources allocated for a first radio access technology and sidelink radio frequency resources allocated for a second radio access technology. The UE may transmit, based on the received co-channel configuration, an indication of a set of channel availability parameter values indicating an amount of available sidelink radio frequency resources associated with the first radio access technology, the second radio access technology, or both. Subsequently, the UE may receive a grant scheduling a set of sidelink resources for the wireless communication associated with the second radio access technology based on the transmitted indication of the set of channel availability parameter values for the co-channel operation.

Abstract: In an aspect, a user equipment (UE) may control one or more reconfigurable intelligent surfaces (RIS) in accordance with one or more RIS schedules that indicate times when the one or more RIS are in an enabled state and times when the one or more RIS are in a disabled state. The UE may request at least one participating UE of one or more participating UEs to transmit at least one positioning reference signal (PRS) in a PRS resource. The UE may measure the at least one PRS from the at least one participating UE in accordance with the RIS schedule to make one or more measurements of the at least one PRS when the one or more RIS are in the disabled state and to make one or more measurements of the at least one PRS when the one or more RIS are in the enabled state.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured to trigger a sidelink message to one or more UE of set of multiple other UEs. The first UE may then generate the sidelink message based at least in part on the triggering. In some cases, the sidelink message may include time and frequency resource information associated with sidelink control information received and processed by the first UE. The first UE may multiplex the sidelink message with a sidelink data message. The first UE may then transmit the sidelink message multiplexed with the sidelink data message to the one or more UE of the set of multiple other UEs.

Abstract: In one aspect, a method of wireless communication includes receiving, by a first user equipment (UE), a first transmission from a second UE for a new radio (NR) sidelink channel. The method also includes receiving, by the first UE, a second transmission from a third UE for the sidelink channel. The method further includes transmitting, by the first UE, a feedback transmission based on a medium contention event for the first and second transmissions of the NR sidelink channel and on a range condition. In additional aspects, the feedback transmission is transmitted based on a quality condition, or both a range condition and a quality condition. Other aspects and features are also claimed and described.
