Abstract: A user equipment (UE) may sense a first transmission by a first sidelink UE and a second transmission by a second sidelink UE and send a conflict indication to at least one of the first or second sidelink UEs in response to identifying a collision between the first and second transmissions, or identifying a prospective collision based on a prospective use of respective first and second resources identified in the respective first and second transmissions. A collision or prospective collision may be detected by detecting a complete or partial overlap of the first and second transmissions or of the prospective first and second resources identified in the transmissions, or by determining that any portions of the first resource and the second resource prospectively occupy a slot common to the first and second resources, and the first sidelink UE and the second sidelink UE prospectively operate in a half-duplex mode.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communication device may transmit, in a radio frequency (RF) spectrum band that supports co-channel coexistence between a first radio access technology (RAT) associated with a first subcarrier spacing (SCS) and a second RAT associated with a second SCS, during a first slot of two or more consecutive slots of a paired transmission, a first redundancy version (RV) of a transport block (TB) that includes a first set of parity bits and a first set of information bits associated with the TB. The wireless communication device may transmit, in the RF spectrum band, during a second slot of the two or more consecutive slots of the paired transmission, a second RV of the TB that includes a second set of parity bits and a second set of information bits associated with the TB.

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: To facilitate coexistence of a first radio access technology (RAT) and a second RAT, methods, apparatuses, and computer program products are provided. An example method of a first wireless device operating based on a RAT includes receiving a sidelink resource reservation from a second wireless device based on a second RAT, the sidelink resource reservation indicating a first set of resources. The example method further includes determining whether to exclude, from a candidate resource set for the first RAT within a sidelink resource pool for the first RAT, resources that overlap with the set of reserved resources for the second RAT. The example method further includes transmitting a sidelink transmission using one or more sidelink transmission resources selected from the candidate resource set in the sidelink resource pool for the first RAT.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first sidelink control information (SCI) from a second UE and a second SCI from a third CE, the first SCI may indicate a first set of resources and the second SCI may indicate a second set of resources that at least partially overlap with the first set of resources. The sets of resources may indicate resources reserved by the UEs for sidelink communications. The first UE may measure a first received power associated with the second UE or a second received power associated with the third UE, or both, based on the overlap and may transmit, to the second UE and/or the third UE, an indication of a conflict based on the first received power and/or the second received power satisfying a condition.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sidelink message using a first beam, where the first sidelink message corresponds to a feedback time interval for receiving feedback associated with the first sidelink message. The UE may transmit a second sidelink message using a second beam that is different from the first beam, where the second beam is also associated with the feedback time interval for receiving feedback associated with the second sidelink message. The UE may then select (from one of the first beam of the second beam) a receive beam to receive feedback during the feedback time interval, and based on the receive beam selection, the UE may monitor for feedback associated with the first sidelink message or the second sidelink message, or both.
