Abstract: Aspects relate to techniques for configuring intermittent time domain resources that are usable by a user equipment (UE) for communication with a base station. The base station may transmit a usable time domain resource (TDR) configuration to the UE that indicates the usable time resources that are available to the UE for communication with the base station. The UE may then communicate with the base station based on the usable TDR configuration.

Abstract: In a wireless network, a frame structure may include a padding duration at the start of every half subframe to ensure that an integer number of symbols fit within a duration of the half subframe. In some aspects, to avoid wasting time domain resources, the padding duration may be utilized for other purposes. For example, because a single carrier waveform is not bound to a fixed Fast Fourier Transform size, a wireless node may use the padding duration to transmit a single carrier symbol that has a shorter length than a full symbol associated with a subcarrier spacing. Additionally, or alternatively, in cases where a wireless node is configured to transmit or receive a signal in a first symbol of a half subframe that is associated with a different power level than a preceding symbol, the padding duration may be used to adapt a transmit power or a receive gain.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, one or more first signals that indicate a resource allocation and that indicate a set of guard interval (GI)-based waveform parameters for a GI-based waveform associated with the UE. The UE may receive, from the network entity, an indication of one or more quantized resource allocation parameters associated with the GI-based waveform. The indication may include one or more formulas for determination of the one or more quantized resource allocation parameters, the one or more quantized resource allocation parameters, or both. The UE may communicate the GI-based waveform with the network entity using the one or more quantized resource allocation parameters and the set of GI-based waveform parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A relay user equipment (UE) may transmit, to a network entity, a relay report message including information supporting full duplex relaying of reverse link signaling from the remote UE. Such a relay report message may include information that facilitates relaying of the reverse link communications while reducing or mitigating cross-link interference (CLI), self-interference (SI), or both, in a full duplex (FD) mode. For example, the relay report message may include information triggering beam sweeping, beam selection, resource selection, etc., for the relaying of the reverse link communications. In some examples, a network entity may configure sidelink UEs with an FD sidelink slot format that supports sidelink transmissions in the final symbol of a sidelink slot (e.g., instead of relying on one or more gap symbols).

Abstract: A relay UE may identify feasibility of FD relaying at the relay UE. The FD relaying at the relay UE may include simultaneous downlink reception from a network node and sidelink transmission to a remote UE. The relay UE may transmit, for the network node, an FD relay assistance information message based on the identified feasibility of the FD relaying at the relay UE. The network node may schedule a first downlink transmission from the network node to the relay UE and at least one first sidelink transmission from the relay UE to the remote UE based on the FD relay assistance information message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, using a sidelink with a second UE, a first indication of one or more candidate full-duplex (FD) beam pairs selected by the first UE for an FD sidelink transmission. The UE may receive, using the sidelink, a second indication that specifies at least part of an FD beam set that includes a first FD beam pair associated with the first UE and a second FD beam pair associated with the second UE, the FD beam set being based at least in part on the one or more candidate FD beam pairs. The UE may communicate with the second UE using the sidelink based at least in part on the FD beam set and the FD sidelink transmission. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating multiplexing of time-varying DMRS within a symbol are disclosed herein. An example method for wireless communication at a receiving device includes receiving a first symbol of a single carrier waveform, the first symbol including a first set of DMRS resources. The example method also includes receiving a second symbol of the single carrier waveform, the second symbol including a second set of DMRS resources, the second set of DMRS resources associated with at least one of a DMRS starting location and a DMRS duration that is different than the first set of DMRS resources.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for flexible intra-symbol multiplexing of DMRS of different antenna ports for single carrier waveforms. A base station may transmit one or more DMRSs within a symbol and provide an intra-symbol guard interval prior to each of the one or more DMRSs. The intra-symbol guard interval may have a duration that is based on a duration of a CP. A UE may receive the one or more demodulation reference signals DMRSs within the symbol based on the intra-symbol guard interval prior to each of the one or more DMRSs, and perform a channel estimation based on at least one of the one or more DMRSs.

Abstract: Apparatus, methods, and computer-readable media for coexistence of multiple uplink control channel formats for wireless communication with power spectral density limitation are disclosed herein. A user equipment (UE) may communicate, with a base station (BS) over a random access channel on a first set of random access resources or a second set of random access resources, a random access request based on a comparison between an intended transmit power of the random access request and a reference transmit power threshold. The UE may communicate, on a first set of uplink resources, a control message for initial network access when the random access request is communicated on the first set of random access resources. The UE also may communicate, on a second set of uplink resources, the control message when the random access request is communicated on the second set of random access resources.
