Abstract: Methods, systems, and devices for wireless communications are described that support signaling of compressed gradient vectors in a machine learning system that utilizes federated learning. The compressed gradient vectors may be used to report stochastic gradients from multiple edge devices (e.g., multiple user equipment (UE) devices) that are combined into a global model at an edge server (e.g., a base station). A base station may configure a UE with one or more parameters for quantizing a local stochastic gradient, and for reporting the quantized local stochastic gradient in a set of compressed gradient vectors. Each vector of the compressed gradient vectors may be associated with a different stage of a multi-stage compression procedure for reporting the local stochastic gradient, and multiple reports from multiple UEs may be aggregated in a federated learning procedure associated with a machine learning algorithm.

Abstract: Some techniques and apparatuses described herein provide sub-grouping of paging groups of user equipment (UEs) based at least in part on one or more parameters associated with a UE, such as a UE type of the UE or a measured channel condition at the UE. A base station may assign the UE to a paging sub-group based at least in part on the information associated with the one or more parameters. In some aspects, the base station may determine paging transmission parameters for the UE based at least in part on the information associated with the one or more parameters, such as a paging early indication (PEI) location, a beam where a PEI and/or a paging message is to be transmitted, a number of repetitions for a paging occasion, or the like.

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: A method of wireless communication by a user equipment (UE), comprises inputting sensor data, captured at the UE, to a local machine learning model. The method also includes extracting features from the sensor data, with the local machine learning model, while anonymizing the sensor data. The method further includes transmitting the features to a base station, and receiving a handover decision from the base station based on the features. A method of wireless communication by abase station inputs anonymized sensor feature data, received from a user equipment (UE), into a network machine learning model. The base station also inputs handover decision information into the network machine learning model. The method further includes inferring a handover decision based on the handover decision information and the anonymized sensor feature data, and transmitting the handover decision to the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a downlink control information (DCI) mode to be used by the UE, wherein the selected DCI mode is one of: a joint DCI mode in which a DCI for an uplink and a DCI for a downlink are monitored jointly, or a separate DCI mode in which one or more of the DCI for the uplink or the DCI for the downlink are monitored separately; and monitor at least one of the DCI for the uplink or the DCI for the downlink in accordance with the selected DCI mode. Numerous other aspects are provided.

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.
