Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a slot based at least in part on a transmit beam, wherein the slot is associated with a plurality of slot repetitions using different transmit beams. The UE may transmit, to the network node in the slot and based at least in part on a metric associated with a beam pair satisfying a threshold, feedback to early terminate remaining slot repetitions of the plurality of slot repetitions using the different transmit beams. Numerous other aspects are described.

Abstract: Aspects of the disclosure relate to reporting and correcting a spatial misalignment of an orbital angular momentum (OAM) waveform communicated from a second device to a first device. In an aspect, the first device receives from the second device, the OAM waveform having a spatial misalignment with respect to the second device. The first device determines the spatial misalignment and further determines spatial coordinates for correcting the spatial misalignment and/or one or more channel measurements of the OAM waveform. Thereafter, the first device sends a report based on the spatial misalignment to the second device, the report including the spatial coordinates for correcting the spatial misalignment and/or the one or more channel measurements. The first device then receives an adjusted OAM waveform from the second device, wherein the adjusted OAM waveform is received having a corrected spatial alignment with respect to the second device based on the report.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, when a high subcarrier spacing (SCS) is used for sidelink communications, the user equipments (UEs) may use a modified sidelink slot structure for the sidelink communications. In one example, the slot structure may include at least two automatic gain control (AGC) symbols with at least one sidelink control channel symbol between the two AGC symbols. The UE may perform an AGC procedure during the two AGC symbols and the sidelink control channel symbol. In some examples, the slot structure may include bundled slots to minimize per slot overhead associated with AGC symbols and sidelink control channel symbols. For example, at a high SCS, the slot structure may include a first slot including multiple AGC symbols, Subsequent bundled slots may not include AGC symbols and/or sidelink control channel symbols.

Abstract: Methods, systems, and devices for wireless communications are described. Polar coding involves assigning bits to different bit-channels, and encoding the bits such that certain bit-channels (e.g., polar channels) are polarized to increased reliability, while other bit-channels are polarized to decreased reliability. To ensure that polar codes for extended reality (XR) and video applications have increased reliability for the aspects of an XR stream or video code that are most important, the information bits of a stream may be sorted based on priority or importance. Then the sorted information bits may be mapped to the most reliable bit-channels of a polar encoder. Any errors in the transmission may therefore be most likely to occur in the less important bits. Accordingly, in the case of XR, the information bits that are most important to user experience/perception are the most likely to be successfully received and decoded at the receiver.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications device may receive a waveform including both a first waveform comprising an orthogonal frequency division multiplexing (OFDM) waveform and a second waveform comprising a single-carrier waveform via a set of time-frequency resources. The wireless device may decode the first waveform based on receiving the waveform, where the first waveform includes one or more reference signals. The wireless communications device may decode the second waveform based on receiving the waveform and on a time domain equalization filter that is based on decoding the one or more reference signals, where the second waveform comprises a set of data bits. In some examples, the waveform may further include a third waveform including a second OFDM waveform and the wireless communications device may decode the third waveform including one or more second reference signals based on receiving the waveform.

Abstract: Wireless communication techniques for supporting, selecting, and using multiple waveforms and/or multiple decoders for downlink wireless communication are discussed. A UE may transmit to a base station an indication of one or more downlink waveforms or decoders supported by the UE. The UE may also transmit to the base station an indication of power consumption associated with at least one of the one or more downlink waveforms or decoders. The UE may receive from the base station an indication of a waveform or decoder, based on the indication of power consumption, to use for downlink wireless communication.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine to enable orbital angular momentum (OAM) beamforming for communications with a user equipment (UE), for example, based on one or more communications parameters and receiving a message from the UE indicating a capability of the UE to use OAM beamforming. The base station may transmit control signaling to the UE indicating that OAM beamforming is enabled. In some examples, the base station may transmit control signaling indicating an OAM configuration, which may be for a same slot in which the control signaling is transmitted or a subsequent slot. The base station may transmit a downlink transmission to the UE via OAM beamforming. In some examples, the base station may estimate and correct misalignment associated with OAM beamforming. In some examples, the base station may disable OAM beamforming and transmit an indication that OAM beamforming is disabled.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine the subcarrier spacing and carrier frequency used by a user equipment (UE) for communicating with the base station. The base station may select a sounding reference signal (SRS) configuration for the UE that is based on the subcarrier spacing and carrier frequency used by the UE. The SRS configuration may define the temporal spacing between repetitions of the SRS. The base station may indicate the SRS configuration to the UE so that the UE transmits repetitions of the SRS according to the SRS configuration. The base station may measure the SRS repetitions from the UE to determine the Doppler frequency for the uplink channel. The base station may use the uplink Doppler frequency to select a demodulation reference signal (DMRS) configuration for the UE.
