Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to measure self-interference between multiple transmission reception points (TRPs) of the UE and initiate sidelink full duplex communications based on the measured self-interference. The UE may transmit a message to a base station to request resources for sidelink communications by the UE and indicate an intended self-interference measurement by the UE using the resources. The base station may transmit a grant scheduling the resources for the self-interference measurement by the UE. The UE may measure interference between a TRP of the UE that is configured for transmission and a TRP of the UE that is configured for reception using the scheduled resources. The UE may transmit a sidelink feedback message indicating resources that are available for sidelink full duplex communications by the UE based on the measured self-interference.

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: Apparatus, methods, and computer program products for resource allocation for multi-TRP sidelink communication are provided. An example method includes receiving one or more signals comprising sidelink control information (SCI) at multiple TRPs of the sidelink device, the SCI indicating a resource reservation. The example method further includes decoding the SCI based on the one or more signals measuring a reference signal received power (RSRP) associated with the SCI at each of the multiple TRPs. The example method further includes. The example method further includes determining available resources for sidelink transmission for a subset of one or more of the multiple TRPs based on the RSRP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, at a second protocol layer of the UE and from a first protocol layer of the UE, the second protocol layer being lower than the first protocol layer, an indication of one or more quality of service parameters associated with a data packet to be transmitted by the UE. The UE may identify, from the one or more quality of service parameters, directional coverage information associated with the data packet, the directional coverage information indicative of one or more transmission directions in which the data packet is to be transmitted. The UE may transmit the data packet in accordance with at least the directional coverage information of the one or more quality of service parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a second UE, a first sidelink synchronization signal (SLSS) at a first transmission-reception point (TRP) and a second TRP different from the first TRP. The first UE may perform a first set of measurements on the first SLSS received at the first TRP and a second set of measurements on the first SLSS received at the second TRP. The first UE may then transmit, to a third UE, a second SLSS based at least in part on the first set of measurements, the second set of measurements, or both, satisfying one or more measurement thresholds.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques at a user equipment (UE) provide for efficiently falling back to a half-duplex mode from a full-duplex mode when a level of interference is high. In particular, the UE may measure the level of interference at the UE (e.g., caused at least partially by self-interference between transmissions and receptions at the UE), and the UE may fall back to a half-duplex mode if the level of interference is above a threshold. In one example, the UE may transmit channel state information (CSI) reference signals (CSI-RSs) on resources allocated for interference measurements, and the UE may perform measurements on the CSI-RSs to identify a level of interference. In another example, the UE ay transmit a data packet on resources allocated for interference measurements, and the UE may decode the data packet to identify a level of interference.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may receive configuration information that indicates a set of resources for self-interference measurement associated with a full-duplex communication mode; transmit a signal in accordance with the configuration information; determine a self-interference measurement based at least in part on the signal and the set of resources; and transmit information indicating the self-interference measurement. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, to a base station, a buffer status report for a first sidelink transmission to a device. The first UE may receive, from a second UE, sidelink control information scheduling the first UE for a time resource for a second sidelink transmission from the second UE, the sidelink control information including an indication of a serving cell identifier of the second UE. The first UE may detect a half-duplex scheduling conflict, or a possible half-duplex scheduling conflict, based on the serving cell identifier and transmit an indication of the conflict to a serving base station. The base station may then assign, or re-assign, resources for the first sidelink transmission to avoid the scheduling conflict.
