Abstract: A UE determines an occurrence of a condition to trigger transmission of inter-UE coordination information based on a CR being below a threshold CR associated with a priority level for the inter-UE coordination information and transmits a sidelink message that includes the inter-UE coordination information in response to the occurrence of the condition for the inter-UE coordination information.

Abstract: Certain aspects of the present disclosure provide techniques for indicating and categorizing resources in an inter-UE coordination (IUC) message, triggering a UE to send IUC messages to other UEs, and identifying recipient UE (s) for IUC messages. An example method performed by a user equipment (UE) generally includes: detecting at least one condition is met for triggering transmission of an inter-UE coordination (IUC) message; including, in the IUC message, an indication of at least one second UE that is an intended recipient of the IUC message and an indication of resources for the second UE to consider for its own resource selection; and transmitting the IUC message.

Abstract: A wireless device that supports sidelink communication may transmit a sidelink transmission in a first set of one or more slots. The wireless device may measure a received signal strength indicator (RSSI) in a second set of slots, the RSSI indicative of a channel busy ratio (CBR) over a combined set of slots including both the first set of one or more slots and the second set of slots and transmit the sidelink communication based on the CBR associated with the combined set of slots.

Abstract: To provide more power efficient SPS transmission for sidelink UEs, methods, apparatuses, and computer-readable medium are provided. An example method may include selecting a first sidelink transmission resource for SPS based on a sidelink sensing procedure for UE to UE communication, the first sidelink transmission resource being associated with one or more subchannels within one or more slots. The example method may further include initiating a timer based on a timer range, the timer range being based on one or more of a battery level or a mobility associated with the UE. The example method may further include reselecting to a second sidelink transmission resource or maintain the first sidelink transmission resource for the UE to UE communication upon expiration of the timer.

Abstract: A first UE and at least one second UE are disclosed. The first UE may identify one or more resources that are suitable for a subsequent transmission from at least one second UE. The first UE may transmit to the at least one second UE, an inter-UE coordination message and at least one data transmission. The inter-UE coordination message may be transmitted at a same time as the at least one data transmission. The inter-UE coordination message may include an indication of the one or more resources that are suitable for the subsequent transmission from the at least one second UE. In one configuration, the inter-UE coordination message may be piggybacked with the at least one data transmission. The at least one second UE may transmit the subsequent transmission via the one or more resources, or may reselect the one or more resources based on the inter-UE coordination message.

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: 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: The apparatus may be a first UE. The first UE may determine a first set of candidate BPLs associated with a first SL and a second set of candidate BPLs associated with a second SL. The first UE may further determine a configuration for FD beam training based on the determined first set of candidate BPLs and the determined second set of candidate BPLs, the FD beam training configuration may include multiple instances for which the first UE transmits and receives RS at a same time. The apparatus may also select, based on the determined FD beam training configuration, a first BPL in the first set of candidate BPLs for the first SL and a second BPL in the second set of candidate BPLs for the second SL. The first UE may establish FD communication with the second UE based on the selected first BPL and the selected second BPL.

Abstract: According to some aspects, a wireless device may indicate to another device a receive configuration indicator (RCI) to indicate a receive spatial configuration of the wireless device. For example, a first device may configure the first device to receive, from a second device, a signal using a first receive spatial configuration of the first device that corresponds to a first transmit spatial configuration of the second device. The first device may further determine a RCI to indicate the first receive spatial configuration of the first device, and may transmit the RCI to the second device.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) transmits, by a transmitter transmit-receive point (TRxP) of the transmitter UE on a transmit beam, a self-interference management reference signal (SIM-RS) during a first beam training occasion shared among a plurality of UEs for transmitting beam training reference signals (BT-RS) for sidelink communications among the plurality of UEs, and measures, by a receiver TRxP of the transmitter UE on a receive beam, self-interference at the receiver TRxP caused by transmission of the SIM-RS by the transmitter TRxP.
