Abstract: Methods, systems, and devices for wireless communications are described. User equipments (UEs) that operate in sidelink mode 2 may be configured with or agree upon time windows in which full-duplex communication is supported and time windows in which half-duplex communication is supported. The UEs may agree upon beam pair links to be used for full-duplex communication during the full-duplex time windows. A first UE may transmit sidelink control information (SCI) that schedules a first sidelink shared channel communication in a first communication resource in a time window that is configured for full-duplex communication. Based on the SCI, a second UE may identify that the first sidelink shared channel communication is scheduled in the first communication resource in a full-duplex time window and may transmit a second sidelink shared channel communication to the first UE in a second communication resource that at least partially overlaps with the first communication resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, reference signals using transmit (Tx) beams of the first UE based at least in part on a Tx beam sweeping, wherein self-interference measurements associated with the first UE are based at least in part on the reference signals. The first UE may transmit, to the second UE, an indication of candidate full duplex Tx-Rx beam pairs, wherein the candidate full duplex Tx-Rx beam pairs are based at least in part on the self-interference measurements. The first UE may receive, from the second UE, an indication of a full duplex Tx-Rx beam pair selection from the candidate full duplex Tx-Rx beam pairs. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) or a base station may generate a discrete Fourier transform (DFT) waveform from separate DFT inputs of data content, a guard interval (GI) sequence, and tail suppression samples. The UE or the base station may generate a first communication with the DFT waveform using an inverse fast Fourier transform (IFFT) operation. The first communication may include, in a time domain, a data signal corresponding to the data content and a GI-based tail signal that corresponds to the GI sequence and that is suppressed with a tail suppression signal based at least in part on the tail suppression samples. The UE or the base station may transmit the first communication. Numerous other aspects are described.

Abstract: The apparatus may be a device at a UE or a base station. The UE (or base station) may be configured to measure a phase noise of a first local oscillator associated with a first port. The UE (or base station) may further be configured to configure, based on the measured phase noise, an allocation of a first set of one or more REs of a PUSCH (or PDSCH) for at least one PT-RS associated with the first port. The first set of one or more REs may include multiple layers associated with a multiple-layer single-carrier waveform transmission. The UE (or base station) may also be configured to transmit, to a base station (or a UE), the PUSCH (or PDSCH) including the at least one PT-RS, the at least one PT-RS being transmitted via the configured allocation of the first set of one.

Abstract: Apparatus, methods, and computer-readable media for facilitating reference signal multiplexing with downlink data are disclosed herein. An example method for wireless communication at a user equipment (UE) includes receiving, from a base station, a reference signal configuration associated with at least one of a tracking reference signal (TRS) and a channel state information reference signal (CSI-RS), the reference signal configuration comprising a symbol level rate matching configuration, a precoder configuration, or a guard tone configuration. The example method also includes receiving, from the base station, a transmission comprising at least a reference signal and data based on the reference signal configuration.

Abstract: A method for wireless communication at a first network entity and related apparatus are provided. In the method, the first network entity communicates, with a second network entity, information indicative of a guard interval length. The information indicative of the guard interval length is based on transmission information. The first network entity further communicates, with the second network entity, a transmission including one or more symbols. Each symbol of the one or more symbols includes a particular guard interval based on the information indicative of the guard interval length. The method enables the GI length to be flexibly configured depending on various waveforms or channel parameters and characteristics of the transmission. The method enables transmission resources to be fully utilized according to actual operating conditions. Thus, it improves the efficiency and flexibility of wireless communication.

Abstract: A wireless device (e.g., a UE or a base station) may identify a first subcarrier mapping associated with one or more redundant subcarriers. The one or more redundant subcarriers may correspond to one or more UWs in a UW-OFDM waveform. The wireless device may identify a second subcarrier mapping associated with one or more reference signals. A simultaneous application of the first subcarrier mapping and the second subcarrier mapping may be associated with one or more collisions. The wireless device may modify at least one of the first subcarrier mapping or the second subcarrier mapping to eliminate the one or more collisions. The wireless device may generate the UW-OFDM waveform based on the modified at least one of the first subcarrier mapping or the second subcarrier mapping. The wireless device may transmit a signal based on the generated UW-OFDM waveform.
