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.

A user equipment (UE) may receive an indication of a configuration, for synchronization of a communication link, of a plurality of component carriers (CCs) and respective priorities associated with the plurality of CCs and may receive a plurality of synchronization signals (SSs) via the plurality of CCs. The UE may synchronize with a timing source associated with a wireless device associated with a first CC of the plurality of CCs, and may transmit SSs via one or more of the plurality of CCs. The UE may select the first CC and may transmit the SSs via the one or more of the plurality of CCs based on the respective priorities associated with the plurality of CCs, respective received signal powers of the SSs, a synchronization source priority of the wireless device, one or more reference carriers, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects are directed to enabling co-channel coexistence among UEs. Some aspects may mitigate or prevent collisions between sidelink transmissions, such as collisions between a New Radio (NR) physical sidelink feedback channel (PSFCH) and a Long Term Evolution (LTE) physical sidelink shared channel (PSSCH). Numerous other aspects are described.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, by a first radio access technology (RAT) sidelink module from a second RAT sidelink module, second RAT sidelink reservation information, the second RAT sidelink reservation information indicating a reference signal received power (RSRP) value. The first UE may perform, using the first RAT sidelink module, a first RAT sidelink resource selection based at least in part on the RSRP value indicated in the second RAT sidelink reservation information, wherein the first RAT sidelink resource selection is based at least in part on an exclusion or an inclusion of one or more single slot resources in a non-first-RAT-PSFCH slot or in a first RAT physical sidelink feedback channel (PSFCH) slot. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for acknowledgment feedback for groupcast option 1 sidelink communication are disclosed herein. An example method of wireless communication at a receiving user equipment (UE) includes determining whether a data signal associated with a groupcast transmission from a transmitting UE is decodable at the receiving UE and obtaining measurements of the data signal when the data signal is decodable at the receiving UE. The example method also includes determining whether the measurements exceed a threshold and transmitting a first type of feedback to the transmitting UE when the measurements do not exceed the threshold. An example method of wireless communication at a transmitting UE includes receiving, from a receiving UE over a sidelink channel, feedback comprising the first type of feedback when the first UE is determined to monitor for the first type of feedback and a second type of feedback from a plurality of UEs.

Abstract: Aspects presented herein may enable a UE to transmit or broadcast inter-UE coordination information to one or more UEs based on a set of dedicated-resources or a set of non-dedicated resources. In one aspect, a first UE configures one or more resources in a set of dedicated resources or in a set of non-dedicated resources for a transmission of an inter-UE coordination message, the inter-UE coordination message being associated with at least one of a first stage SCI format or a second stage SCI format. The first UE transmits the inter-UE coordination message via the one or more resources in the set of dedicated resources or in the set of non-dedicated resources.
