Abstract: A method of wireless communication, by a user equipment (UE), includes receiving multiple neural network training configurations for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes training each of a group of neural network decoder/encoder pairs in accordance with the received training configurations.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit feedback to a base station indicating phase values for sub-bands in a bandwidth part (BWP). The base station may use the phase feedback to perform precoding on a set of beams. To support a reduced payload overhead for the feedback, the UE may implement differential phase feedback. For example, the UE may divide the BWP into a number of sub-band groups and may generate, for each sub-band group of each beam, a first set of bits indicating an absolute phase value for a first sub-band of the sub-band group. The UE may additionally generate a second set of bits indicating differential phase values for the other sub-bands of each sub-band group. The UE may report the first and second sets of bits for the beams to the base station for precoding.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform channel state information (CSI) measurements on one or more reference signal transmissions received from a base station. Based on the CSI measurements, the UE may generate a CSI report, and the UE may transmit the CSI report to the base station. In some cases, the generated CSI report may include a first portion and a second portion. The first portion may indicate whether the second portion of the CSI report includes full-band CSI feedback or partial-band CSI feedback. The second portion may provide the CSI feedback for one or more identified sub-bands. In some cases, the second portion may include a sub-band index indicating the identified sub-bands. Additionally or alternatively, the second portion may include a bitmap indicating a correspondence between multiple CSI feedback values and multiple corresponding sub-band indexes.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may perform a wireless sensing procedure, such as radar sensing, based on a sensing pattern defining one or more sensing signal burst occasions. A base station may transmit signaling including a request to suspend the wireless sensing procedure based on a resource collision, or scheduling conflict, between the one or more sensing signal burst occasions used for the wireless sensing procedure and one or more resources used for communications between the UE and the base station. The UE may determine to suspend the wireless sensing procedure or reject the data transmission during the resources that collide. The UE may selectively continue the wireless sensing procedure or pause the wireless sensing procedure based on the determining.

Abstract: 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.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a first base station transmitting a control message to a user equipment (UE). The control message may include an indication to perform a measurement during one or more resources associated with the first base station and that correspond to a second base station. The UE may measure reference signals transmitting via the beam of the second base station and during the time and frequency resources of the first base station. Based on the measurements, the UE determine an interference status correspond to the beam of the second base station and transmits an indication of the interference status to the first base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a resource for measuring cross link interference (CLI). The UE may determine that the resource overlaps with (e.g., at least partially overlaps) one or more symbols or a transmission occasion. The UE may determine, according to what the resource overlaps with, whether to measure CLI over the resource. For example, if one or more of the symbols is uplink or if the resource verlaps a transmission occasion, the UE may not measure CLI. If one or more of the symbols are downlink, the UE may measure CLI. If one or more of the symbols is flexible or has an unknown type, the UE may determine whether to measure CLI based on a type of the control signaling.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may transmit, to a victim user equipment (UE) a configuration message indication one or more resource for measuring cross-link interference (CLI) from an aggressor UE. The configuration message may include one or more cell parameters, which may include an indication of a relationship between the serving cell of the victim UE and the serving cell of the aggressor UE. The victim UE may determine the relationship between the serving cells based on the received cell parameters, and may perform CLI measurements based thereon. In some cases, the UE may adjust a CLI measurement window, or may prioritize some aggressor UEs, based on the determined relationship. The UE may also transmit a CLI measurement report to the base station.
