    摘要: Disclosed are methods, systems, and computer-readable medium to perform operations including: determining that a user equipment (UE) is connected to a cell of a network using a connection in a standalone (SA) mode; based on determining a bandwidth part (BWP) of the connection, accessing a physical cell identifier (PCI) list associated with the UE for a time period; based on the number of PCI values in the list and a duration of the time period, assigning, to a BWP switch timer, a timeout value; initiating the BWP switch timer; and in response to determining that the handover of the UE to the different cell of the network occurs prior to the BWP switch timer reaching the timeout value, causing the UE to switch to a LTE mode.

    摘要: Apparatuses, systems, and methods for a wireless device to perform methods for improvements to security checks in a fifth generation (5G) New Radio (NR) network, including mechanisms to avoid redundant access stratum (AS) security checks. The wireless device may determine that an on-demand system information block (SIB) request is pending transmission and may buffer the on-demand SIB in response to determining that a connection establishment procedure will be initiated within a specified time period. The wireless device may then perform a unified security procedure for the on-demand SIB request and the connection establishment procedure, including confirming connection security. Further, in response to confirming connection security, the wireless device may use an on-demand SIB received from the network without confirming a corresponding on-demand SIB signature.

    摘要: Mechanisms are provided for a user equipment (UE) to determine to use a shared resource such as an antenna to access a land based wireless communication system or a satellite communication system. The UE can provide a first priority indication to indicate whether to access the land based wireless communication system based on one or more wireless link metrics of the land based wireless communication system or one or more application metrics for applications using the land based wireless communication system; and provide a second priority indication to indicate whether to access the satellite wireless communication system based on one or more service metrics provided by the satellite wireless communication system. The UE can determine to use the shared resources to access the land based wireless communication system or the satellite communication system based on the first priority indication and the second priority indication.
