    摘要: Aspects are provided which enhance receiver performance of PDCCH by allowing a base station to associate a configured PDSCH CSI-RS with a PDCCH for channel estimation and reception by a UE. A UE receives a reference signal associated with a physical downlink shared channel (PDSCH) from a base station, and uses the reference signal to receive a physical downlink control channel (PDCCH) and/or measure the PDCCH and feedback a corresponding channel measurement for the PDCCH. A base station configures a reference signal associated with a PDSCH for transmission of a PDCCH and/or reception of a corresponding channel measurement for the PDCCH as feedback from the UE, and transmits the reference signal to the UE.

    摘要: Methods, systems, and devices for wireless communications are described that improve resource configuration for crosslink interference (CLI) measurement in a wireless communications system. For example, a victim user equipment (UE), may be configured to receive and measure the CLI from one or more aggressors. Specifically, the victim UE may be configured to use a dedicated tracking loop for the CLI measurements to track a dedicated channel of the CLI. Additionally or alternatively, the victim UE may associate CLI with an aggressor identity allowing the CLI resources from the same aggressor to be measured jointly. In another example, an aggressor UE may transmit additional reference signals for a victim UE to measure prior to sounding reference signals. The victim UE may report the CLI measurements to its serving base station.

    摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine channel state information for a communication link, wherein the channel state information is based at least in part on a linear combination associated with a plurality of beams of the communication link, wherein a first set of beams used for a first subband, of a plurality of subbands of the communication link, is different than a second set of beams used for a second subband of the plurality of subbands, and wherein the plurality of beams includes the first set of beams and the second set of beams; and transmit the channel state information. Numerous other aspects are provided.

    摘要: Certain aspects of the present disclosure generally relate to methods and apparatus for providing channel state feedback. One example method generally includes receiving at least one first pilot signal, and generating a first channel state information (CSI) report based on the at least one first pilot signal. The first CSI report may include a differential phase feedback for each subband (SB) of one or more SBs associated with the at least one first pilot signal. The method may also include transmitting the first CSI report having the differential phase feedback.
