    Abstract: Methods and systems for mobility management in non-terrestrial networks are disclosed. In one embodiment, a method performed by a first communication node, includes: during a first time period, communicating with a non-terrestrial communication node utilizing a first communication link, wherein the non-terrestrial communication node provides at least one geographic cell in which a user equipment device (UE) is present during the first time period; during a second time period, communicating with a second communication node utilizing a second communication link, wherein a third communication link is established between the non-terrestrial communication node and the second communication node and the first communication link is no longer utilized during the second time period; and determining to maintain the first communication node as an anchor node for communications between a core network and the UE during both the first and second time periods.

    Abstract: This disclosure relates generally to wireless communications and, more particularly, to systems and methods for determining round trip time and layer 2 (e.g., data link) buffer size in non terrestrial networks. In one embodiment, a method performed by a communication node includes: sending a capability request message to a communication device, wherein the communication node communicates from a satellite in orbit; receiving capability information from the communication device in response to the capability request message; and determining a data link buffer size associated with communications between the communication node and the communication device based on the capability information.

    Abstract: Presented are systems, methods, apparatuses, or computer-readable media for communicating system information blocks (SIBs). A wireless communication device may receive a specific System Information Block (SIB) broadcasted by a wireless communication node. The specific SIB may include a list. Each element of the list may be associated with an network identifier (ID) that is broadcasted in a first SIB. Each element of the list may include one or more group identifiers and may be associated with at least one of: one or more groups of credential holders (CHs), or one or more groups of subscription owners (SOs) or the on-boarding networks for on-boarding.

    Abstract: User equipment may request to communicate with a basestation over a contention-based wireless communication channel. The basestation and the user equipment may perform a multiple-step random access protocol to determine whether the user equipment may communicate over the wireless communication channel. The architecture, e.g., the fields and structure of the messages sent by the basestation may indicate the content and type of those same messages.
