Abstract: This disclosure provides systems, methods and apparatus for wireless communications. In one aspect, a device, such as a user equipment (UE) may receive a configuration including one or more channel state information (CSI) measurement resources associated with a set of CSI hypotheses. The set of CSI hypotheses may correspond to a set of transmission configuration indicator (TCI) states, or a CSI interference measurement (CSIIM) resource, or both. The UE may select a first CSI measurement resource of the one or more CSI measurement resources for a channel measurement based on a CSI hypothesis of the set of CSI hypotheses. The UE also may select the CSIIM resource or a second CSI measurement resource for an interference measurement based on the CSI hypothesis of the set of CSI hypotheses. The UE may, as a result, transmit a report based on the channel measurement or the interference measurement, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may communicate, based at least in part on a physical data channel configuration corresponding to a physical data channel, a first extended reality (XR) data communication corresponding to a first physical data channel occasion associated with the physical data channel configuration, wherein a first priority level is associated with the first XR data communication. The network node may communicate a second XR data communication corresponding to a second physical data channel occasion, wherein a second priority level is associated with the second XR data communication, and wherein the second priority level is higher than the first priority level based at least in part on a packet delay budget associated with the physical data channel configuration being within a specified threshold of packet delay. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for determining shared resources associated with one or more user equipments (UEs) for sidelink communications, including control resources and data resources. A first UE may transmit a sidelink request to reserve a subset of data resources to a second UE, and may monitor for one or more sidelink responses indicating a positive sidelink response to the sidelink request, a negative sidelink response to the sidelink request, or both. The second UE may transmit a positive sidelink response if it is available for a data transmission. A third UE may transmit a negative sidelink response if it objects to the data transmission. The first UE may determine, based on monitoring for the one or more sidelink responses, whether to transmit a sidelink confirmation indicating a reservation of the subset of the data resources to the second UE.

Abstract: Systems and techniques are provided for wireless communications. For example, an apparatus (e.g., a user equipment (UE)) may receive a downlink transmission in a first downlink time slot and receiving an update to a scheduling offset associated with a propagation time delay of communications between the apparatus and a network entity. The update indicates an updated scheduling offset. The apparatus may determine a selected scheduling offset as one of the scheduling offset or the updated scheduling offset. The apparatus may transmit, using a second uplink time slot, an uplink transmission associated with the downlink transmission. The second uplink time slot may be determined based on a first uplink time slot and the selected scheduling offset.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more physical downlink shared channel (PDSCH) communications scheduled by downlink control information (DCI). The UE may transmit, for the one or more PDSCH communications, hybrid automatic repeat request (HARQ) feedback using a sub-codebook of a set of sub-codebooks, wherein the sub-codebook is a single-cell scheduling sub-codebook, of the set of sub-codebooks, or a multi-cell scheduling sub-codebook, of the set of sub-codebooks, based at least in part on whether the DCI is a first format configured for scheduling on a single carrier or a second format configured for scheduling on a plurality of carriers. Numerous other aspects are described.

Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information indicating precoding information associated with a multi-panel uplink transmission, the precoding information including at least one of a demodulation reference signal port configuration associated with the multi-panel uplink transmission, a multiple-input multiple-output precoding configuration associated with the multi-panel uplink transmission, or a quantity of layers associated with the multi-panel uplink transmission. The UE may precode the multi-panel uplink transmission for transmission via a first antenna panel of the UE and a second antenna panel of the UE based at least in part on the precoding information. The UE may transmit, using the first antenna panel and the second antenna panel, the precoded multi-panel uplink transmission. Numerous other aspects are provided.

Abstract: A UE may identify, during a first DRX ON period immediately preceding an existing DRX OFF period, that a first condition is met. The UE may transmit, to a network node, and the network node may receive, from the UE, a request to extend the first DRX ON period based on the first condition being met. The network node may transmit, to the UE, and the UE may receive, from the network node, an indication of approval of the request to extend the first DRX ON period. The UE and the network node may delay a beginning of the existing DRX OFF period by a first time period based on the approval of the request to extend the first DRX ON period.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently identifying resources for transmitting one or more sidelink synchronization signal blocks (S-SSBs) in the shared spectrum or efficiently beam sweeping multiple S-SSBs in the shared spectrum. In one aspect, a user equipment (UE) may transmit an S-SSB in a sidelink bandwidth part (BWP) in the shared spectrum such that a lower edge of the S-SSB is aligned with or offset from a lower edge of the sidelink BWP. In another aspect, a UE may beam sweep S-SSBs in one or more S-SSB bursts in a S-SSB period to improve the chances that another UE may receive the S-SSBs. In yet another aspect, resources allocated for S-SSB transmissions may facilitate flexible S-SSB transmissions while minimizing gaps to prevent other UEs from incorrectly determining that a sidelink BWP in a shared spectrum is clear for transmission.
