Abstract: Certain aspects of the present disclosure provide techniques for a user equipment (UE) to efficiently provide feedback regarding preferred beams to a base station (BS) that transmits with different beams from different elevations. The techniques generally involve the BS transmitting first reference signals transmitted, using a plurality of elevation beams. The UE selects at least one preferred elevation beam based on the first reference signals and feeds this back to the BS. The BS transmits second reference signals using the preferred elevation beam and a plurality of azimuthal ports. The UE provides a second stage channel feedback to the base station, based on the second reference signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may transmit a message indicating that the first device is operating on intermittently available energy harvested from outside the first device. The first device may receive a low-power wakeup signal. The first device may transmit, based at least in part on an energy harvesting state of the first device, an indication that the first device is capable of supporting continuous transmission and reception during a time frame having a configured duration. The first device may communicate during the time frame. Numerous other aspects are described.

Abstract: Aspects described herein relate to receiving a configuration indicating a first codebook subset restriction table restricting a set of precoding matrix indicators (PMIs) for which PMI feedback is to be reported for an antenna array, generating, based on the configuration, PMI feedback for an adaptive configuration of the antenna array based on a second codebook subset restriction table for the adaptive configuration of the antenna array, and transmitting the PMI feedback to the base station. Other aspects relate to transmitting the configuration and/or receiving the PMI feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive an indication of a first transmit power configuration and a second transmit power configuration for a physical uplink shared channel (PUSCH) communication. The wireless communication device may transmit, using a first transmit power that is based at least in part on the first transmit power configuration, a first portion of the PUSCH communication in a full-duplex portion of a time-frequency resource. The wireless communication device may transmit, using a second transmit power that is based at least in part on the second transmit power configuration, a second portion of the PUSCH communication in a non-full-duplex portion of the time-frequency resource. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a beam report associated with a set of base station transmit beams, the set of base station transmit beams being directed to the UE via a backscatter link reflected by a backscatter device. The UE may transmit, to the base station, the beam report based at least in part on the configuration of the beam report, the beam report corresponding to the backscatter link. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an intermediate orbital angular momentum (OAM) node may receive, from a parent OAM node via a parent link between the intermediate OAM node and the parent OAM node, a first signal based at least in part on a first set of OAM modes. The intermediate OAM node may transmit, to a child OAM node via a child link between the intermediate OAM node and the child OAM node, a second signal based at least in part on a second set of OAM modes that are different than the first set of OAM modes. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first downlink control information (DCI) message of a two-stage set of DCI. The UE may receive, from the base station, a second DCI message of the two-stage set of DCI. The UE may select between the first DCI message and the second DCI message as a timing reference point. In some examples, the UE may receive, from the base station, downlink data on the physical downlink channel. In some examples, the UE may transmit, to the base station, an uplink data message on the physical uplink channel.

Abstract: Disclosed are techniques for communication. In an aspect, a position estimation entity determines a sidelink positioning reference signal (SL-PRS) resource configuration associated with a positioning measurement procedure. The position estimation entity transmits an indication of the SL-PRS resource configuration (e.g., to first and/or second UEs). The UE(s) obtain the SL-PRS resource configuration, and perform the positioning measurement procedure in accordance with the SL-PRS resource configuration.
