Systems and techniques are provided for performing wireless communications. In some aspects, a use equipment (UE) may receive a crosslink interference (CLI) training session configuration from a network entity, wherein the CLI training session configuration corresponds to a CLI training session for a plurality of UEs including the UE. The UE may determine a CLI feedback information associated with performing the CLI training session and may transmit the CLI feedback information to the network entity. The CLI feedback information may be indicative of CLI between the UE and one or more additional UEs.

Distributed cross-link interference (CLI) management

A UE may estimate a CLI channel state based on a ZP-SRS from a second UE. A network node may transmit to the UE, and the UE may receive from the network node, a CSI-RS. The UE may estimate a downlink channel state based on the CSI-RS from the network node. The UE may estimate one or more eCSF parameters based on the CLI channel state, the downlink channel state, two or more interference hypotheses, and at least one of a CPU specification, a timing specification, or a UE capability indication. The UE may transmit to the network node, and the network node may receive from the UE, an eCSF report based on the one or more eCSF parameters.

CPU, timing, and capability specifications for eCSF report based on projected CLI in FD

Apparatus, methods, and computer program products for cross-link interference (CLI) measurements are provided. An example method may include receiving, from a second network entity, a configuration of a set of semi-persistent (SP) or periodic (P) (SP/P) CLI measurement resources for layer 2 (L2) CLI measurement, where the set of SP/P CLI measurement resources are associated with one or more measurement resource types including at least one of: a zero power sounding reference signal (ZP SRS), a channel state information (CSI) interference measurement (CSI IM) resource, a non-zero power (NZP) CSI reference signal (CSI RS), or a combination of the NZP CSI RS and CSI IM, where the one or more measurement resource types are tied to at least one respective CLI reporting metric or not tied to the respective CLI reporting metric.

L2 CLI measurement and reporting

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on an estimated cross link interference (CLI) at the UE. For example, a network entity may indicate, to a first UE and a second UE, transmission parameters of a multi-port CLI-reference signal (CLI-RS) that is associated with estimation of CLI channel between the first UE and the second UE. The network entity may indicate, to the first UE, one or more precoding parameters associated with uplink precoding at the second UE. The second UE may transmit the multi-port CLI-RS to the first UE, and the network entity may transmit a CSI-reference signal (CSI-RS) to the first UE. The first UE may transmit a report that includes CSI based on the multi-port CLI-RS, the CSI-RS, and the one or more precoding parameters.

Cross link interference based channel state information reporting

Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE) generally including receiving, from a network entity, signaling scheduling a number of Physical Downlink Shared Channel (PDSCH) repetitions for the UE, successfully decoding one of the PDSCH repetitions that was transmitted before a remaining one or more of the PDSCH repetitions, and transmitting early acknowledgment feedback to a network entity indicating the successful decoding, wherein the early acknowledgment feedback is transmitted before transmission of at least one of the remaining PDSCH repetitions.

Early acknowledgement feedback

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating a frequency hopping configuration for repetitions of an uplink message that are to be transmitted via a set of resources, including one or more resources that support full-duplex communications. The UE may determine that some resources of the set of resources are available for transmitting the repetitions in a time domain. The UE may use a frequency hopping pattern to transmit the uplink message and the repetitions of the uplink message, where the frequency hopping pattern may include two or more frequency hops and based on the available resources and the frequency hopping configuration. In some cases, the UE may determine that some resources of the set of resources are unavailable in a frequency domain, and as such, the UE may drop respective transmissions of the uplink messages on the unavailable resources.

Frequency hopping and available slot determination for full-duplex operation

Methods, systems, and devices for inter-UE cross link interference (CLI) characteristics are described. A UE may transmit, to a network entity, capability information indicating a capability of the UE to support one or more schemes for determining characteristics of an inter-UE CLI channel. The network entity may transmit, based on the capability information, an indication of a selected scheme of the one or more schemes for determining the characteristics of the channel. The UE may perform a set of measurements of the characteristics and may transmit assistance information in accordance with the selected scheme. The assistance information may pertain to the channel and may include the set of multiple measurements. The UE may also transmit an indication of the channel's variation or an indication of a coherence time. The network entity may transmit one or more updated channel parameters in response to receiving the assistance information.
