Abstract
A method of training an artificial neural network (ANN), receives, from a base station, signal information for a radio frequency signal between the base station and a user equipment (UE). The artificial neural network is trained to determine a location of the UE and to map the environment based on the received signal information and in the absence of labeled data.
Claims22
A method of localization and mapping using an artificial neural network (ANN), comprising:
- receiving, via the ANN, signal information from one or more base stations for radio frequency signals between the one or more base stations and a user equipment (UE);
- and
- determining, via the ANN, a location of the UE based on the signal information.
A method of localization and mapping using an artificial neural network (ANN), comprising:
- receiving, via a base station, signal information from one or more user equipments (UEs) for radio frequency signals between the one or more UEs and the base station;
- and
- determining locations of the one or more UEs based on the signal information.
An artificial neural network comprising:
- an encoder configured to determine a location of one or more user equipments (UEs) based on signal information from the one or more UEs for radio frequency signals between the one or more UEs and a base station;
- a decoder configured to parameterize a propagation environment of the one or more UEs based at least in part on the location of the one or more UEs.
A method of operating an artificial neural network (ANN), comprising:
- receiving transmissions of radio frequency (RF) signals from one or more reference nodes;
- and
- inferring from the RF signals or signal information derived from the RF signals, a location of a receiver of the RF signal transmissions relative to the one or more reference nodes.
