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: Disclosed are techniques for wireless positioning. In an aspect, a first network node receives, from a second network node, a positioning reference signal having a first reception time at the first network node, receives, from a first user equipment (UE), a first uplink positioning reference signal having a second reception time at the first network node, receives, from a second UE, a second uplink positioning reference signal having a third reception time at the first network node, and enables a first reference signal time difference (RSTD) measurement to be calculated for the first UE and a second RSTD measurement to be calculated for the second UE based on the first reception time, the second reception time, the third reception time, and other measurements.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may detect whether a data sample falls outside of a dataset used to train a machine learning model configured by a network device. For example, a base station may transmit control signaling to the UE to indicate an out-of-distribution (OOD) detection rule configuration that the UE uses to determine whether at least one data sample falls outside of the dataset. If the at least one data sample is determined to fall outside of the dataset using the OOD detection rule configuration, the UE may transmit an indication to the base station that indicates an OOD event has occurred for the at least one sample. Additionally, the base station may parameters for determining the OOD event, OOD detection patterns to indicate when to monitor for the OOD event, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described that support blind decoding limit adjustment techniques. A base station may configure a user equipment (UE) with one or more conditions that may trigger an adjustment to a number of blind decoding candidates that are to be monitored at the UE for a control information communication from the base station. A nominal number of blind decoding candidates may be configured at the UE, and the adjustment to the number of blind decoding candidates may reduce the number of blind decoding candidates from the nominal number, thus allowing the UE to perform blind decoding using less processing power, less time, or both. The trigger conditions may include one or more configured conditions that may support reliable communications with fewer blind decoding candidates.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may transmit a slot format indicator (SFI) to a first user equipment (UE) via downlink control information (DCI) and the first UE may use the SFI to determine time-domain resources over which the first UE may measure cross link interference (CLI) arising from a transmission from a second UE. The first UE may use the SFI as an index into a slot format combination table, which may also be used for uplink and downlink scheduling or may be exclusively used for determining the time-domain resources for CLI measurement. The first UE may determine a set of slot formats from a slot format table based on a slot format combination corresponding to the SFI index and may determine over which symbols the first UE may measure CLI based on the set of slot formats.

Abstract: Techniques for enabling a cross-link interference (CLI) based uplink (UL) angle-of-arrival (AoA) estimations are disclosed. A victim user equipment (UE) may be configured with CLI resources to measure CLIs from one or more aggressor UEs. The victim UE may take the CLI opportunities also to estimate the AoAs of the UL signals from the aggressor UEs. In this way, UE's location estimation may be enhanced.

Abstract: Aspects relate to a configuring cross link interference (CLI) measurements. In some examples, a base station may configure a first user equipment (UE) to relay a CLI configuration to a second UE. In response, the second UE may send a CLI measurement report to the first UE whereby the first UE relays the CLI measurement report to the base station. In some examples, a base station may configure a first UE to schedule CLI measurements. In this case, the first UE may generate a CLI configuration for a second UE and send the CLI configuration to the second UE. The second UE may then send a CLI measurement report to the first UE. In some examples, a base station may send a CLI configuration to a UE and the UE may send a CLI measurement report to another UE that relays the CLI measurement report to the base station.

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.
