    摘要: Certain aspects of the present disclosure provide techniques for transmitting demodulation reference signals (DMRS) with control channels (e.g., physical downlink control channels (PDCCHs)) that enable receiving devices to bundle (e.g., coherently combine) the DMRS over time. A UE may detect a portion of a PDCCH to the UE in at least one resource element group (REG), wherein the REG is in a segment of a control resource set (CORESET) configured for the UE or a group of UEs including the UE and the REG is during a first search space (SS) set occasion configured for the UE or the group of UEs; and process wideband (WB) DMRS in the segment during the first SS set occasion and in the segment during at least one second SS set occasion, wherein the UE does not detect another portion of the PDCCH or another PDCCH during the second SS set occasion.

    摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a victim user equipment (UE) may measure a cross-link interference strength from an aggressor UE based at least in part on an uplink transmission from the aggressor UE colliding with a downlink transmission to the victim UE. The victim UE may transmit cross-link interference information to the aggressor UE on a sidelink channel. For example, the cross-link interference information transmitted to the aggressor UE may indicate at least the cross-link interference strength measured by the victim UE. Numerous other aspects are provided.

    摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine that at least one condition, of a plurality of conditions, is satisfied with regard to at least one other base station; and perform at least one remote interference management (RIM) operation, the at least one RIM operation selected based at least in part on the at least one condition. In some aspects, a base station may receive an indication regarding interference, the indication regarding interference indicating that at least one condition, of a plurality of conditions, is satisfied with regard to the base station or at least one other base station; and perform at least one RIM operation, the at least one RIM operation selected based at least in part on the at least one condition or the indication regarding interference. Numerous other aspects are provided.

    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.
