Abstract: 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.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit an indication of a time parameter (e.g., a time delay or a configured duration) associated with determining a configuration for a slot duration. A user equipment (UE) may identify the time parameter and receive an indication of a slot configuration. The UE may determine the configuration of one or more slot durations based on the received indication and according to the time parameter. For instance, the UE may determine the configuration of one or more slots after the time delay. In some other examples, the UE may determine the configuration of one or more slots within the configured duration, and may not use different slot configurations until after the duration expires. The base station and the UE may communicate during the one or more slot durations based on the slot configuration and using the time parameter.

Abstract: 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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information that indicates, for a plurality of signals configured in a symbol, a plurality of quasi-colocation (QCL) relationships to be used for determining a channel property; select a QCL relationship, from the plurality of QCL relationships, to be used for determining the channel property and the plurality of signals in the symbol; and receive the plurality of signals in accordance with the selected QCL relationship based at least in part on the channel property. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a first control resource set (CORESET) configured for a first category of UEs and a second CORESET configured for a second category of UEs with which the UE is associated, wherein the first CORESET has a first frequency domain resource allocation, and wherein the second CORESET overlaps in time with the first CORESET and has a second frequency domain resource allocation that is a subset of the first frequency domain resource allocation. The UE may monitor for a physical downlink control channel (PDCCH) candidate based at least in part on a determination that the PDCCH candidate is fully contained within the second frequency domain resource allocation. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive an indication of a first transmit power configuration and a second transmit power configuration for a physical uplink shared channel (PUSCH) communication. The wireless communication device may transmit, using a first transmit power that is based at least in part on the first transmit power configuration, a first portion of the PUSCH communication in a full-duplex portion of a time-frequency resource. The wireless communication device may transmit, using a second transmit power that is based at least in part on the second transmit power configuration, a second portion of the PUSCH communication in a non-full-duplex portion of the time-frequency resource. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatuses for enabling a cross link interference (CLI) measurement resource indication. In some aspects, a first user equipment (UE) may receive configuration information indicating multiple CLI measurement resources that are associated with measuring CLI from a second UE. A network entity may configure a CLI measurement resource set, including the multiple CLI measurement resources, for the first UE to measure CLI associated with the second UE. The first UE may receive a communication indicating a CLI measurement resource, from the multiple CLI measurement resources, to be used to measure the CLI from the second UE. The indication of the CLI measurement resource to be used by the first UE may enable the CLI measurement resource used by the first UE to be dynamically changed to ensure that the CLI measurement resource aligns with an active bandwidth part (BWP) of the second UE.
