Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may obtain a sidelink resource pool configuration indicating multiple waveforms that are available for use for sidelink signals associated with a sidelink resource pool. The first UE may communicate, with a second UE and via a sidelink channel, a first sidelink signal associated with the sidelink resource pool, wherein the first sidelink signal uses a first waveform from the multiple waveforms, and wherein the first waveform is used based at least in part on at least one of: a condition associated with the sidelink channel, or receiving a communication indicating that the first waveform is to be used by the first UE. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a guard period associated with switching from a first communication mode to a second communication mode. The UE may be operating in a half-duplex frequency division duplexing mode of operation. The guard period may be determined based at least in part on at least one of: a number of phased locked loops to be used for the first communication mode and the second communication mode, and a particular subcarrier spacing associated with the UE. The UE may switch from the first communication mode to the second communication mode based at least in part on the guard period. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer readable mediums for retransmitting a random access channel (RACH) message, for example, based on parameters for initial RACH transmission. For example, a user equipment (UE) transmits an initial transmission of an uplink RACH message with repetition. The UE receives a downlink control information (DCI) scheduling a retransmission of the uplink RACH message with repetition. The UE determines parameters for the retransmission of the uplink RACH message with repetition based, at least in part, on parameters for the initial transmission of the uplink RACH message with repetition. The UE retransmits the uplink RACH message to the network entity with repetition in accordance with the determined parameters.

Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for duplex switching based on network power modes. A UE may receive a first indication that a first power mode of a network entity is associated with a first duplex type for the network entity and a second power mode of the network entity is associated with a second duplex type for the network entity. The first duplex type and the second duplex type may correspond to at least one of full-duplex communication or half-duplex communication. The UE may receive a second indication of a switch from the first power mode associated with the first duplex type to the second power mode associated with the second duplex type and communicate with the network entity based on the second power mode and the second duplex type for the network entity.

Abstract: A configuration configuring a UE to establish a connection with one or more candidate relays in preparation of switching to a target relay from one or more candidate relays. The apparatus receives, from a source relay, a candidate relay configuration, the candidate relay configuration including at least information of candidate relays. The apparatus measures a reference signal of the source relay and each of the candidate relays based on the candidate relay configuration. The apparatus establishes a connection with a subset of candidate relays. The apparatus transmits, to the source relay, a measurement report of the reference signal of the subset of candidate relays. The apparatus receives, from the source relay, a relay switch command to switch to a target relay from the subset of candidate relays.
