Abstract: A first UE may transmit, to a second subset of one or more second UEs, one or more pilot signals associated with DPD training. The first UE may receive, from a third subset of the one or more second UEs, one or more feedback messages associated with DPD training. The one or more feedback messages may be based on the one or more pilot signals. Each second UE in the third subset of the one or more second UEs may correspond to one of the one or more feedback messages. The second UE may calculate one or more DPD parameters based on the one or more feedback messages. The second UE may transmit a first signal based on the calculated one or more DPD parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a downlink communication is to be transmitted having tone reservation applied to one or more subcarriers of a downlink channel based at least in part on the downlink channel, the one or more subcarriers having indices associated with a set of verification bits. The UE may decode the downlink communication based at least in part on the tone reservation being applied to the one or more subcarriers and based at least in part on the set of verification bits. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media are disclosed herein for facilitating spatial misalignment tracking for OAM beams in millimeter wave and higher frequency bands. An example method for wireless communication at a first communication device includes receiving, from a second communication device, a first misalignment tracking RS and a second misalignment tracking RS for an OAM transmission. The example method also includes determining a misalignment based on the first misalignment tracking RS, the second misalignment tracking RS, and using a subset of antenna elements of an antenna array of the first communication device. Additionally, the example method includes adjusting reception of a subsequent OAM transmission from the second communication device at the antenna array of the first communication device.

Abstract: Certain aspects of the present disclosure provide techniques for downlink control information (DCI) format for power efficiency. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a first DCI message in a first symbol of a downlink control channel, the first DCI message comprising a portion of an identifier that consists of less than all parts of the identifier, the first symbol being one of a plurality of symbols in a time period. The method may also include, when the portion of the identifier corresponds to the UE, receiving downlink data via resources indicated by a second DCI message, the second DCI message received in a second symbol of the downlink control channel, the second DCI message indicating the resources for receiving downlink data, the second symbol being another one of the plurality of symbols in the time period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules a communication, wherein the DCI indicates information for one or more parameters of the communication using differential information associated with information included in an anchor DCI. The UE may transmit or receive the communication based at least in part on receiving the DCI. Numerous other aspects are described.

Abstract: A first wireless communication device includes a plurality of antenna elements, a transceiver coupled to the plurality of antenna elements, and a focusing element positioned in a transmitting path of at least one of the plurality of antenna elements. The transceiver is configured to transmit, to a second wireless communication device, a multiple-input multiple-output (MIMO) signal. The transceiver configured to transmit the MIMO signal is configured to: transmit, to the second wireless communication device via a first antenna element of the plurality of antenna elements, a first communication signal; and transmit, to the second wireless communication device via a second antenna element of the plurality of antenna elements, a second communication signal. The focusing element is configured to: direct the first communication signal in a first direction; and direct the second communication signal in a second direction different from the first direction.

Abstract: Aspects of disclosure relate to beam steering at a multi-antenna device. The device receives an activation signal to activate one or more input ports of a Butler matrix and outputs signals from all output ports of the Butler matrix based on activation of the one or more input ports. The signals output from the output ports have varying phase shifts relative to each other. Moreover, the device phase shifts the signals output from the output ports via a plurality of phase shifters respectively coupled to the output ports. The phase shifted signals have further varying phase shifts relative to each other and a phase difference between adjacent phase shifted signals. Each one of a plurality of antenna elements at the device receives a phase shifted signal from an associated phase shifter and outputs a beam based on the phase shifted signal received from the associated phase shifter.
