Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, to a base station, capability signaling including an indication of a capability of the first UE to prioritize reception of downlink messages scheduled via a first type of scheduling which at least partially overlap with resources used to perform cross-link interference (CLI) measurements. The first UE may receive control signaling indicating a first set of resources for a downlink message, and additional control signaling indicating a second set of resources usable by the first UE to perform CLI measurements on signals transmitted by a second UE, where the second set of resources at least partially overlap with the first set of resources in a time domain. The first UE may then receive the downlink message from the base station within the first set of resources based on the indication of the capability.

Abstract: In methods and devices configured to perform the methods for managing downlink traffic reception and cross-link interference (CLI), a wireless device may receive from a base station physical downlink control channel (PDCCH) traffic using a first receive (Rx) resource tuning of an Rx resource, determine whether a time period between an end of the PDCCH traffic and a beginning of a CLI measurement opportunity exceeds a threshold duration for tuning the Rx resource to a second Rx resource tuning, and may receive downlink traffic using the first Rx resource tuning in response to determining that the time period between the end of the PDCCH traffic and the beginning of the CLI measurement opportunity is less than or equal to the threshold duration.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a base station, a configuration indicating an interference reciprocity between the first UE and a second UE, where the interference reciprocity is associated with cross link interference (CLI) between the first UE and the second UE. The first UE may also receive, from the base station, an indication of a transmit power of the second UE. The first UE may measure a pathloss associated with the CLI between the first UE and the second UE based at least in part on the received transmit power of the second UE. The first UE may determine a transmit power for transmission of one or more uplink messages based at least in part on the measured pathloss and transmit the uplink messaged using the determined transmit power.

Abstract: Example aspects include a method, apparatus, and computer-readable medium of managing cross-link interference (CLI) by a first network node of a wireless communication network, comprising generating a reflection coefficient measurement configuration for an intelligent reflecting surface (IRS) controlled by the first network node to mitigate the CLI caused by a first user equipment (UE) controlled by the first network node to a second UE controlled by a second network node. The aspects further include transmitting network information comprising the reflection coefficient measurement configuration. Additionally, the aspects further include receiving, in response to transmitting the network information, CLI measurement information associated with the second UE. Additionally, the aspects further include identifying a particular reflection coefficient from a set of different reflection coefficients associated with the reflection coefficient measurement configuration. Additionally, the aspects further include configuring the IRS with the particular reflection coefficient.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may communicate with a base station to measure cross-link interference (CLI) from an aggressor UE. The first UE may receive a CLI measurement configuration which provides a CLI measurement resource for the first UE to use for measurement of CLI from an aggressor UE. The first UE may select, based on a selection priority, a reference cell for estimation of a CLI measurement resource timing. The first may determine a reference cell timing based on a reference signal of the reference cell, and the first UE may estimate the CLI measurement resource timing based on the reference cell timing. The first UE may measure CLI from the aggressor UE in accordance with the CLI measurement resource timing.

Abstract: A first user equipment (UE) receives, from a scheduling entity, one or more indications of one or more parameters associated with an uplink (UL) transmission from a second UE. The UL transmission includes one or more cross link interference (CLI) measurement resources. The first UE configures one or more dedicated tracking loops for receiving the one or more CLI measurement resources of the UL transmission based on the one or more indications of the one or more parameters. The first UE receives, from the second UE, the one or more CLI measurement resources of the UL transmission using the one or more dedicated tracking loops according to the one or more parameters, while also receiving a downlink (DL) transmission from the scheduling entity. The first UE determines one or more CLI measurements using the one or more CLI measurement resources of the UL transmission.

Abstract: In an aspect, a BS determines a CLI measurement resource configuration associated with first and second UEs, the reciprocal CLI measurement resource configuration comprising resources associated with both a CLI measurement procedure and an RTT measurement procedure between the first UE and the second UE. The BS transmits the reciprocal CLI measurement resource configuration to the first and second UEs. The first and second UEs perform both the CLI measurement procedure and the RTT measurement procedure with the second UE based on the resources associated with the reciprocal CLI measurement resource configuration.
