Abstract: Methods and apparatus for predicting wireless measurements based on virtual access points is described. In some embodiments, a location of a user equipment (UE) may be obtained, and given the location of the UE, an output may be generated using a machine learning model, the output including one or more predicted wireless measurements. The output may be indicative of a wireless channel in a multipath environment. In some variants, the machine learning model may have been trained by obtaining a training dataset including multipath components data and ground truth locations of a wireless device, and performing an optimization with respect to the multipath components data and the ground truth locations. In some implementations, a training output including a predicted multipath component may be produced during the training, and the optimization may include an iterative minimization of an error between at least the predicted multipath component and a labeled multipath component.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for detecting when a control link between a user equipment (UE) and a base station is lost and recovering the control link. In one example, a UE may detect that a control link with a base station is lost based on a timer or counter expiring or based on failing to receive signaling from the base station. In another example, a UE may be configured to transmit uplink transmissions to a base station to maintain a control link with the base station, and the base station may detect that a control link with the UE is lost if the base station fails to receive one or more uplink transmissions from the UE. If the control link is lost, the base station and the UE may communicate to re-establish the control link.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a base station (BS). In some examples, the techniques include receiving, from a user equipment (UE), one or more indications of one or more actual beam strengths as measured at the UE at one or more time periods for one or more transmit beams of the BS. In some examples, the techniques include receiving, from the UE, assistance information regarding the one or more actual beam strengths.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive signaling from a network entity via a cell. The signaling may indicate a state of resource utilization associated with at least the cell. The UE may modify a compression scheme in accordance with the state of resource utilization. The compression scheme may be used at the UE for compressing channel state information (CSI) associated with a layer used for wireless communication between the UE and the network entity via the cell.

Abstract: Disclosed is a method for wireless communication. The method comprises receiving, from a network node, a reference signal (RS) of a first type. An input signal of a second type is determined based on the reference signal. Signals of the second type are associated with training a first machine learning (ML) model applied by a UE to estimate a parameter used in wireless communications by the UE. The input signal of the second type is applied to the first ML model to estimate the parameter used in wireless communications by the UE.

Abstract: A UE may identify, in each round other than an initial round, a first plurality of local model update elements of a present round. The first plurality of local model update elements of the present round may be associated with an updated local machine learning model. The UE may transmit to a base station, in each round other than the initial round, over a multiple access channel via analog signaling, a second plurality of local model update elements of the present round based on a third plurality of local model update elements of the present round. The third plurality of local model update elements of the present round may correspond to a sum of the first plurality of local model update elements of the present round and a local model update error of a previous round immediately before the present round. The analog signaling may be associated with OTA aggregation.
