  • Publication number: 20220361275
    Abstract: A wireless device (12) transmits, to a network node, a non-access stratum, NAS, recovery report (20) that reports a cause (22) of the wireless device (12) performing a NAS recovery procedure for NAS recovery of an access stratum, AS, signaling connection (16). The network node, based on the NAS recovery report (20), may perform root cause analysis to determine a root cause of the wireless device (12) having to perform the NAS recovery procedure. Alternatively or additionally, the network node may, based on the NAS recovery report (20), perform one or more actions to address a root cause of the wireless device (12) having to perform the NAS recovery procedure.

  • Publication number: 20220303775
    Abstract: The present disclosure relate to a method performed by a UE (102) for handling an invalid SI signature in a communication system. The UE obtains SI and an associated SI signature for a cell. The UE (102) determines if the obtained SI signature is valid or invalid. If the signature is valid, the UE (102) determines to use the cell. If the SI signature is invalid, the UE (102) determines if the UE (102) is configured to bar cells or not. If the SI signature is invalid and if the UE (102) is not configured to bar cells with invalid SI signature, the UE (102) determines to use the cell. If the SI signature is invalid and the UE (102) is configured to bar cells with invalid SI signature, the UE (102) determines to bar the cell and select another cell to use.

  • Publication number: 20220272539
    Abstract: The present disclosure relates to a method performed by a UE (102) for handling validity of a SI signature in a com-munication system. The UE (102) obtains, from an access node (103, 104), SI and an associated SI signature for a cell served by the access node (103, 104) and which the UE (102) can use. The UE (102) determines if the obtained SI signature is valid or invalid. The UE (102) determines that the cell is valid if the SI signature is determined to be valid. The UE (102) determines that the cell is invalid if the SI signature is determined to be invalid. The UE (102) provides information indicating the invalid cell to the access node (103, 104) or to another node if the SI signature is determined to be invalid.

  • Publication number: 20220132451
    Abstract: The present disclosure relates to transmitting synchronization signals and in particular to so called beam sweep. In particular the disclosure relates to methods for providing synchronization using synchronization sequences that are transmitted at different points in time. The disclosure also relates to corresponding devices and computer programs. A method in a network node, for transmitting synchronization sequences of a synchronization signal to one or more receiving wireless devices, comprises determining multiple synchronization sequences, such that each synchronization sequence comprises a respective timing indication, whereby each synchronization sequence enables determination of a time of an event in a receiving wireless device and transmitting the synchronization sequences to the one or more wireless devices, at different points in time.
