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: In various embodiments supporting directional security, a user equipment (UE) may receive from a network device a noise resource allocation including an indication of a noise direction and a noise parameter, generate a noise signal based at least in part on the noise parameter, and transmit the noise signal in the noise direction while transmitting a communication transmission signal in a different direction from the noise direction. In various embodiments, a network device may determine a geographic zone of interest, select one or more reconfigurable intelligent surfaces (RISs) associated with the geographic zone of interest, selecting one or more noise transmitting UEs, control the one or more noise transmitting UEs to transmit at least one noise signal, and control the one or more RISs to steer the at least one noise signal into the geographic zone of interest.

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: Certain aspects of the present disclosure provide techniques for slot format for sidelink communication. A method that may be performed by a user equipment (UE) includes refraining from transmitting during a gap portion of a first symbol in time of a sidelink transmission, wherein the first symbol comprises the gap portion and a signal portion; transmitting a signal during the signal portion of the first symbol; and transmitting a data signal of the sidelink transmission in at least one second symbol subsequent in time to the first symbol in the sidelink transmission.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for sidelink resource selection with AD usage awareness. A UE may receive, from one or more ANs, one or more resource usage schedules associated with one or more ADs in communication with the one or more ANs. The UE may combine the one or more resource usage schedules associated with the one or more ADs into a combined resource usage schedule. The usages may be associated with the combined resource usage schedule, which may be indicative of excluded resources for a transmission of the UE. The UE may transmit, based on the combined resource usage schedule, the transmission of the UE on a resource other than the excluded resources.
