Abstract: Certain aspects of the present disclosure provide techniques for enhanced sidelink (SL) control signaling with time division duplexing (TDD). A method that may be performed by a first user equipment (UE) may include receiving a TDD configuration indicating resources of a resource pool available for SL transmissions between the first UE and at least a second UE and exchanging SL communications with the second UE in one or more slots or symbols based, at least in part, on the TDD configuration. The TDD configuration may define one or more of the slots or symbols as flexible slots or symbols that may be configured as downlink (DL) or uplink (UL) slots or symbols. The TDD configuration may also identify one or more of the slots or symbols as UL slots or symbols and one or more slots or symbols as DL slots or symbols.

Abstract: To facilitate more efficient sidelink communications, methods, apparatuses, and computer program products are provided. An example method of a user equipment (UE) may include determining a configuration of a set of congestion control measurement resources comprising one or more receiving resources and one or more transmitting resources for transmission of an activity indication signal for sidelink communication. The example method further includes measuring received signal strength indicator (RSSI) on at least one of the one or more receiving resources.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PUCCH/PUSCH DMRS bundling. A UE may transmit, to a network entity, a first indication of a maximum DMRS bundling duration for maintaining transmit phase coherence for transmitted DMRS. The UE may receive, from the network entity based on the first indication of the maximum DMRS bundling duration, a second indication of at least one of a DMRS bundling activation or a DMRS bundling duration. Based on the at least one of the DMRS bundling activation or the DMRS bundling duration, the UE may transmit at least one UL repetition including bundled DMRS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive, from a second wireless communication device, an announcement associated with a first future communication and that indicates a set of resources associated with the first future communication. The first wireless communication device may communicate using the set of resources based at least in part on a determination that an estimated interference that will result from a second future communication using the set of resources satisfies an interference condition. Numerous other aspects are described.

Abstract: Aspects of the present disclosure describe determining an uplink channel raster for determining frequency location of an uplink channel over which to transmit uplink communications to a base station. Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

Abstract: Certain aspects of the present disclosure provide techniques for determining priority information associated with hybrid automatic repeat request (HARQ) feedbacks for wireless nodes in sidelink communications. A subset of the HARQ feedbacks are selected based on the priority information. The selected HARQ feedbacks are then transmitted to the second wireless nodes.
