Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes, a first user equipment (UE) may receive, from a second UE, a coordination message indicating a set of resources associated with sidelink communications and a preference of the second UE for one or more subsets of the set of resources. The first UE may transmit the sidelink communications using one or more resources of the set of resources based on the preference of the second UE for the one or more subsets of the set of resources. In some examples, the one or more resources may be selected from candidate resources within a resource selection window of the first UE. Additionally, or alternatively, the candidate resources may be based on the preference of the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may estimate one or more channel availability parameter values. The UE may then select, based on a co-channel configuration indicating a relationship between channel availability parameter values and patterns of sidelink resources, a pattern of sidelink resources (e.g., LTE resources) on which to transmit NR packets. In some examples, a special UE may receive individual or aggregated reports of channel availability parameter values. The special UE may select a pattern of sidelink resources (e.g., LTE resources) on which one of the reporting UEs is permitted to transmit NR packets, and may transmit a message activating the pattern of sidelink resources to the reporting UE. The reporting UE may then use the activated sidelink LTE resources for transmitting NR packets according to the indicated pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may reserve a set of sidelink resources for a first sidelink transmission. A detecting UE may identify a sidelink feedback channel collision arising from a first sidelink feedback transmission to a first UE and a second sidelink feedback transmission to a second UE sharing same feedback channel resources. The detecting UE may determine one or more UEs to transmit a sidelink feedback channel collision indication to, and transmit, the collision indication to the one or more UEs. The first UE may identify a collision involving the first sidelink feedback transmission associated with the first sidelink transmission and the second sidelink feedback transmission associated with a second sidelink transmission by the second UE. The first UE may determine to transmit or retransmit the first sidelink transmission based on the sidelink feedback channel collision being identified.

Abstract: Methods and devices for wireless communications are described. A first user equipment (UE) may establish a first sidelink connection with a second UE and a second sidelink connection with a third CE. The first UE may receive an indication of a first set of transmission resources for the second UE to use to transmit to the first UE. The first UE may transmit an indication of a second set of transmission resources for the second UE to use to transmit to the first UE, the second set of transmission resources identified by the first UE based at least in part on comparing signals received using the first transmission reception point with signals received using the second transmission reception point. The first UE may receive a data message from the second UE on the second set of transmission resources.

Abstract: Apparatus, methods, and computer-readable media for sidelink control information forwarding for sensing procedure are disclosed herein. An example method of wireless communication at a forwarding user equipment (UE) includes receiving, from a forwarded UE, control information, and transmitting, to a sensing UE, a forward message including the control information and information associated with the forwarded UE. An example method of wireless communication at the sensing UE includes receiving, from the forwarding UE, a forward message including the control information containing a first measurement of the control information. The example method also includes obtaining a second measurement of the forward message and determining a ratio of the second measurement to the first measurement. The example method also includes selecting a specific resource based on the ratio and whether the forwarding UE is an intended receiver for the sensing UE or the forwarding UE intends to receive from the forwarded UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may identify beamforming information for transmitting a pre-reservation signal that indicates a set of non-preferred resources associated with a data transmission. The UE may transmit, to a receiver UE in accordance with the beamforming information, the pre-reservation signal that indicates the set of non-preferred resources associated with the data transmission. Numerous other aspects are described.

Abstract: Techniques for sidelink (SL) and uplink (UL) full duplex communication with multiple transmission and reception points (multi-TRP) may be performed. In an example, a user equipment (UE) may determine full duplex communication, including simultaneous reception of a SL communication from an SL UE via a first TRP of the UE and transmission of a UL transmission to a base station via a second TRP of the UE, is available. The UE may enable the full duplex communication. The UE may receive, from the SL UE, the SL communication via the first TRP. The UE may transmit, to the base station while simultaneously receiving the SL communication, the UL transmission via the second TRP.

Abstract: Aspects relate to dynamic resource sharing for sidelink communication. In some examples, a user equipment (UE) may modify a first sidelink transmission resource set associated with a first radio access technology (RAT) to exclude at least one resource indicated by a second sidelink transmission resource set associated with a second RAT. In some examples, a UE may prioritize certain transmissions. For example, a UE may drop a sidelink reception operation if there is a conflict with a sidelink transmission operation. In some examples, a UE may prioritize a particular RAT. For example, a UE may drop a sidelink transmission operation on a first RAT if there is a conflict with a sidelink transmission operation on a second RAT (e.g., the second RAT is deemed to have a higher priority).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to one or more other UEs, one or more sidelink reference signal block (S-RSB) bursts in a sidelink beam measurement gap (SBMG) based at least in part on one or more SBMG configurations. The UE may receive, from the one or more other UEs, one or more beam reports or beam measurement reports based at least in part on the one or more S-RSB bursts and the one or more SBMG configurations. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may schedule a multi-transmission reception point (mTRP) UE for concurrent uplink and sidelink transmissions based on interference measure. For example, abase station may determine an amount of interference associated with resources used for sidelink communications between the mTRP UE and a second UE. Based on the determined amount of interference, the base station may transmit a resource grant to the mTRP UE indicating a first set of resource for transmitting one or more uplink messages to the base station and a second set of resources for transmitting one or more sidelink messages to the second UE, where the first set of resources and the second set of resources at least partially overlap in time.
