摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE), served by a cell of a base station, may identify a time division duplexing (TDD) configuration for a first cell, wherein the TDD configuration includes a symbol pattern for a slot. The base station may determine an overlap between a downlink symbol or a flexible symbol and an uplink symbol during symbols of the slot based on a TDD configuration. A first UE may receive a configuration for transmitting a cross-link interference (CLI) sounding reference signal (SRS) to a second UE according to the configuration. The second UE may measure the CLI SRS and report the measurement.

摘要： User Equipment (UE) receives, from a base station (BS), at least one resource block (RB). The RB includes at least one reference signal (RS) resource element (RE) of a first physical channel of the UE. The UE estimates a channel quality of a second physical channel of the UE as a function of the at least one RS RE. In some examples, the BS associates the transmission of a first physical channel reference signal (RS) and the transmission of a second physical channel RS. The BS then signals, BS to the UE, the association between the first physical channel reference signal and the second physical channel reference signal.

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： Aspects described herein relate to receiving, by a node, a signal from a different node for determining a level cross-link interference from the node, determining, by the node, that the signal, as received from the different node, has a frequency pre-compensation applied by the different node, and measuring the signal, based on determining that the signal has the frequency pre-compensation applied, to determine the level of cross-link interference from the different node.

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 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.
