Abstract: Aspects directed towards receiving at a sidelink node from and communicating to peer sidelink nodes an indication on whether the CDD antenna diversity scheme is used in a data transmission are disclosed. Also disclosed is the receiving sidelink node optimizing its operation based on the knowledge of whether the CDD antenna diversity scheme is used in the data transmission and thus the performance at the receiving sidelink node is improved. Also disclosed are aspects directed to a peer sidelink node determining whether to use the CDD antenna diversity scheme based on a variety of factor and conveying the determination to the receiving sidelink node.

Abstract: Methods, systems, and devices for wireless communications are described. A base station in a network of base stations may determine a predicted route of a user equipment (UE) based on sensor data obtained by sensors coupled with the base station. A neighboring base station may be located along the predicted route and the base station may provision the neighboring base station with a subset of beams associated with the neighboring base station. The subset of beams may include beams with geographic coverage areas overlapping with the predicted route of the UE. The base station may add the subset of beams to a provisioned route beam list and may transmit the provisioned route beam list to the neighboring base station in a message. The neighboring base station may use the subset of beams indicated in the provisioned route beam list for beamforming communications with the UE.

Abstract: This disclosure provides methods, devices and systems for pre-compensation of downlink communication based on a transmission of a request for the pre-compensation from a user equipment (UE). For example, the UE may determine an impairment at the UE that has a greater severity (a greater impact on downlink communication) or is associated with a greater amount of resources for processing relative to a remainder of a set of impairments that is experienced at the UE and the UE may transmit a request for pre-compensation of the impairment by a base station. The base station may transmit feedback to the UE indicating a confirmation of pre-compensation for the impairment by the base station or to deferment of compensation for the impairment back to the UE. If the base station acknowledges pre-compensation for the impairment, the base station may pre-compensate a downlink transmission to the UE for the impairment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit a request, for an uplink transmission or a downlink transmission, for data aided phase tracking reference signals (PT-RSs) on multiple layers of a communication link; and communicate the uplink transmission or the downlink transmission based at least in part on the request. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a Hybrid Automatic Repeat Request (HARQ) protocol using multiple beams. In some aspects, the UE may receive a first HARQ transmission from a base station (BS) via a first beam, and may transmit a HARQ feedback to the first BS. The BS may receive the HARQ feedback message and determine whether to transmit a HARQ retransmission associated with the first HARQ transmission via the first beam or via a different beam (such as a second beam) based on beam-specific conditions. The BS may provide a HARQ retransmission beam indication to the UE indicating that the HARQ retransmission will be transmitted via the second beam. The BS may transmit the HARQ retransmission via the second beam. The UE may receive the HARQ retransmission associated with the first HARQ transmission via the second beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first beam, of a set of beams configured for spatial division multiplexing (SDM), for reception of a downlink control information (DCI) message associated with a second beam of the set of beams. The UE may receive, via the first beam, the DCI message associated with the second beam. Numerous other aspects are described.

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.
