Abstract: Certain aspects of the present disclosure provide techniques and apparatus for improved machine learning. A sequence of data records is accessed, each data record comprising wireless channel measurements and inertial measurement unit (IMU) data. Known position information corresponding to at least a first data record is accessed. A first sequence of positions is determined by processing the sets of IMU data and known position information using a forward operation. A second sequence of positions is determined by processing the sets of IMU data and known position information using a backward operation. An IMU adjustment parameter is generated using the first and second sequences of positions. A pseudo-label is generated for a second data record using the IMU adjustment parameter and the sets of IMU data. A machine learning model is trained, using the second data record and the pseudo-label, to predict positions using one or more wireless channel measurements.

Abstract: A network node may receive a set of sounding reference signals (SRSs) from a wireless device. The network node may measure the set of SRSs. The network node may output at least one of a set of estimated positioning labels, training associated information, or labeling assistance information associated with the set of measured SRSs for a positioning model. In one example, the network node may output the data by training the positioning model based on at least one of the set of estimated positioning labels, the training associated information, the labeling assistance information, or the set of measured SRSs. In another example, the network node may output the data by transmitting, for a network entity, at least one of the set of estimated positioning labels, the training associated information, or the set of measured SRSs for training the positioning model.

Abstract: Apparatuses and methods for multi-hypothesis measurement configuration in RF sensing are described. An apparatus is configured to receive, from a sensing entity, a sensing configuration, wherein the sensing configuration indicates a total number of sensing hypotheses and at least a first sensing hypothesis and a second sensing hypothesis that is different from the first sensing hypothesis; The apparatus is also configured to measure a first set of sensing measurement data associated with the first sensing hypothesis and a second set of sensing measurement data associated with the second sensing hypothesis. The apparatus is further configured to transmit, for the sensing entity, at least one of: (1) the first set of sensing measurement data and the second set of sensing measurement data, or (2) an indication of the first sensing hypothesis and the second sensing hypothesis.
