System and method for tracking an operator with a safety device

Disclosed is a tangible article of manufacture having instructions stored thereon that, when executed, cause a machine to perform operations for tracking an operator and operator status using a safety device. The operations include programming a plurality of NFC tags with assignment information, wherein the assignment information is at least one of a location assignment for NFC tags being placed at particular locations and an instrument operator assignment for NFC tags distributed to multi-gas detection instrument operators. The instructions further include receiving temporary assignment information at the safety device when an NFC radio of the safety device is brought in proximity to at least one of the plurality of NFC tags; and tagging safety device data with the temporary assignment information.

Selecting a non-access stratum period based on a non-terrestrial access network type

A wireless device receives access network information indicating an access network type. Based on the access network type, a non-access stratum (NAS) period is selected among: a first value associated with a geostationary earth orbit (GEO) non-terrestrial network (NTN) access network type; and a second value associated with a low earth orbit (LEO) NTN access network type. A NAS procedure is initiated by sending a NAS request message. A start of the NAS period is based on the sending. The NAS procedure is aborted based on an expiry of the NAS period.

Channel estimation and prediction with measurement impairment

A base station (UE) is configured to perform a computer-implemented method for antenna fault detection and correction. The computer-implemented method includes acquiring one or more sounding reference signals (SRSs) received from at least one gNB antenna; detecting an antenna failure based on the one or more SRSs; estimating a noise power based on the antenna failure and a history of received SRSs; detecting a missing SRS based on the noise power and the history of received SRSs; and handling the missing SRS. Handling the missing SRS is based on performing at least one of: replacing an SRS measurement with a predicted SRS value for the missing SRS when the predicted SRS is available; or avoiding use of the missing SRS in a sequential SRS prediction when the predicted SRS is unavailable.
