  • Patent number: 12262303
    Abstract: A UE activates a timer for applying access control to transmissions associated with a certain access category during an access control period, in response to a first system information message received via a radio interface and a mobile-originated access request (1702). While the timer is running, the UE receives a second message that indicates a potential transition of the UE (i) from a current state associated with a protocol for controlling radio resources to another state associated with the protocol, or (ii) from a current cell to a new cell (1704). In response to the second message, the UE continues to apply the access control to the transmissions for the access category, for a remainder of the access control period (1706).

    Abstract: A user equipment (UE) receives, from a non-terrestrial network (NTN), a measurement configuration that indicates a timing pattern for inter-frequency measurement, the timing pattern including a measurement gap of a certain duration. The UE receives, from the NTN, a synchronization signal during the measurement gap in accordance with the timing pattern, performs a measurement of the synchronization signal; and transmits, to the NTN, an indication related to the measurement gap. For example, the indication may be a request to terminate early the measurement gap.
