Abstract: Apparatus, methods, and computer-readable media for facilitating a multiple bit new data indicator are disclosed herein. An example method for wireless communication at a first device includes transmitting a first state of a multiple bit new data indicator (NDI) for a first packet. The example multiple bit NDI indicates more than two different states for indicating a new packet. The example method also includes transmitting the first packet. Additionally, the example method includes transmitting a second state of the multiple bit NDI for a second packet, and the second state being different than the first state. Further, the example method includes transmitting the second packet.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device may receive control signaling indicating a configuration for reporting a set of beam angle measurement values between at least two beams relative to a respective beam of a set of beams and a phase difference measurement value between post-beamformed channel phases using the at least two beams of the set of beams. In some examples, the communication device may determine a set of reference signal received power (RSRP) measurement values associated with the at least two beams of the set of beams. The communication device may transmit a report including the set of beam angle measurement values and the phase difference measurement value based on receiving the control signaling indicating the configuration. For example, the communication device may report the RSRP measurement values associated with the at least two beams of the set of beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive a configuration associated with reporting delta channel state information (CSI). The first wireless communication device may compute the delta CSI based at least in part on the configuration, the delta CSI indicating a difference between first CSI associated with a first connection and second CSI associated with a second connection, the first connection being between the first wireless communication device and a base station and the second connection being between the first wireless communication device and a second wireless communication device. The first wireless communication device may transmit, based at least in part on the configuration, a CSI report including an indication of the delta CSI and at least one of an indication of the first CSI or an indication of the second CSI. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications supporting techniques for enhanced line-of-sight (LOS) communications with analog multi-path beamforming are described. A first wireless device may receive, from a second wireless device, an indication of a capability of the second wireless device to concurrently transmit first signaling in a first analog beamforming direction using a first transmission configuration indicator (TCI) state corresponding to a LOS mode, and second signaling in a second analog beamforming direction using a second TCI state corresponding to an indirect LOS mode. The first wireless device may then receive, from the second wireless device, a first downlink message in the first analog beamforming direction using the first TCI state concurrently with a second downlink message in the second analog beamforming direction using the second TCI state.

Abstract: Methods, systems, and devices for wireless communications are described. To support a reliable array response for wideband communications, a base station may configure a set of transmission instances for a set of signals distributed across a wideband carrier bandwidth. At least one transmission instance of the set of transmission instances may be configured in each sub-band of the carrier bandwidth. The base station may transmit the set of signals in the configured transmission instances to a user equipment (UE). The UE may receive the set of signals distributed across the carrier bandwidth and may measure, for the signals, a set of signal measurements corresponding to the set of sub-bands. Based on the signal measurements, the UE may determine a set of communication beams for the set of sub-bands. Using one or more of the determined communication beams, the UE may communicate with the base station in the carrier bandwidth.

Abstract: Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A radio access network (RAN) entity (e.g., a scheduling entity, such as a base station or parent integrated access backhaul (IAB) node, or a centralized network node, such as an IAB donor node central unit) may provide support to a scheduled entity (e.g., a user equipment (UE) or child IAB node) to operate in an autonomous time adjustment (ATA) mode to autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. The RAN entity may generate ATA mode information related to the ATA mode for the scheduled entity and transit the ATA mode information to the scheduled entity.
