摘要： Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive, from a base station, a control message including an indication associated with a configuration for an interference measurement (IM) report in a channel state information (CSI) report. The UE may determine a setting of the configuration for the IM report based on the indication, which may include one or both of a resource setting associated with IM information in a frequency domain or a spatial setting associated with IM information in a spatial domain. The UE may generate the IM report based on one or both of the resource setting or the spatial setting and may transmit the CSI report including the IM report to the base station.

摘要： This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a CSI report setting that hastens CSI feedback for SVD-based precoding. More specifically, a UE may receive a configuration from a base station for a CSI report setting for providing DL interference feedback to the base station. The configuration may include information indicating a measurement resource on which an interference measurement is performed for generating the DL interference feedback. The UE may transmit a SRS and the DL interference feedback to the base station, the DL interference feedback being independent of the SRS, such that the UE may receive pre-committed CSI-RS from the base station based on the transmitted SRS and DL interference feedback.

摘要： A second base station may allocate a set of downlink resources for a downlink transmission. The set of downlink resources may include a subset of null resources, which may serve as a signature for the second base station. The second base station may transmit downlink data or reference signals on the set of downlink resources including the subset of null resources. A first UE may experience the downlink transmission from the second base station as interference. The first UE may identify the set of downlink resources. The first UE may identify the subset of null resources. The first UE may transmit, to a first base station, an indication of the subset of null resources. The first base station may identify the second base station based on the indication of the subset of null resources. The first base station may transmit, to the second base station, an interference coordination message.

摘要： 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 grant for a communication with the base station. The UE may determine whether the communication is associated with a hybrid automatic repeat request (HARQ)-based transmission mode or a HARQ-less transmission mode. The UE may communicate with the base station based at least in part on the grant and the determination of whether the communication is associated with the HARQ-based transmission mode or the HARQ-less transmission mode. Numerous other aspects are described.

摘要： Disclosed are techniques for group reporting of UE receive-transmit (Rx-Tx) time difference measurements for multi-RTT positioning. A plurality of downlink reference signals (DL RSs) are received from a plurality of transmission reception points (TRPs). A corresponding plurality of uplink reference signals (UL RSs) are transmitted to the plurality of TRPs. One or more numerology factors are determined for the plurality of TRPs. A measurement report is generated for the plurality of TRPs based on the numerology factors. The measurement report is transmitted to a network entity. The measurement report includes UE receive-transmit (Rx-Tx) time difference measurements for at least two of the TRPs.

摘要： A method of wireless communication by a first network device includes predicting spatial inter-cell downlink interference experienced by a UE. The method also includes communicating with a second network device to reduce the spatial inter-cell downlink interference in a direction of the UE by protecting resources across selected resource sets.

摘要： A configuration for handling downlink traffic jitter in wireless communication systems. The apparatus receives a configuration from a base station comprising a configuration for DRX operation based on a scheduled arrival time of data, wherein the configuration comprises a time offset for a WUS occasion or a DRX on duration for a plurality of DRX cycles of the DRX operation. The apparatus monitors for communication from the base station based on the time offset associated with the WUS occasion or the DRX on duration for each of the plurality of DRX cycles.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine at least one of a downlink path loss value or an uplink path loss value associated with a base station; receive system information, a semi-persistently configured grant via RRC or a dynamic uplink grant via DCI from the base station, wherein the RRC signaling or the dynamic uplink grant identifies a power control value associated with one user or a plurality of users associated with the base station; and determine a transmit power for a data or control transmission based at least in part on at least one of the downlink path loss value or the uplink path loss value and the power control value. Numerous other aspects are provided.

摘要： A base station may precode a first reference signal using a first precoder (P1) and at least one second reference signal using at least one second precoder (P2). At least two UEs may measure the first reference signal and the at least one second reference signal, and transmit channel state feedback based on the measuring (m11 and m12 for a first UE, and m21 and m22 for a second UE). The channel state feedback may comprise channel state information compressed by at least one neural network. The base station may derive a higher-level precoder (W) for multiple-input multiple-output (MIMO) downlink transmission to the at least two UEs.
