Abstract: A wireless terminal receives a network identifier in a message received on a broadcast channel. The wireless terminal determines that a mobile network code in the network identifier corresponds to a non-terrestrial network. The wireless terminal updates a tracking area list of the wireless terminal by adding or deleting a tracking area identifier corresponding to the non-terrestrial network to the tracking area list.

Abstract: This disclosure relates to method and device for serving a user equipment by a first wireless network node. In one implementation, the method may include transmitting a request message for a non-radio-communication service resource of a second wireless access network node to the second wireless access network node. The first wireless access network node may provide the user equipment with a non-radio-communication service and request the non-radio-communication service resource to assist to provide the non-radio-communication service to the user equipment. The method may further include receiving a response message allocating the non-radio-communication service resource for the user equipment from the second wireless access network node.

Abstract: A master node (MN) may receive a secondary node (SN) change required message from a source SN. The MN may send an indication of a maximum number of candidate PSCells that can be configured by a target SN, in an SN addition request message, to the target SN. The MN may receive, from the target SN, at least one candidate PSCell configuration, in an SN addition request acknowledge message, in response to the SN addition request message. The MN may send a RRC message to a wireless communication device, the RRC message including the at least one candidate PSCell configuration and one or more associated CPAC execution conditions.

Abstract: A system and method for improving mobility performance. The system and method include receiving, by a target master wireless communication node (MN) from a source master wireless communication node (MN), a handover request to begin a handover procedure; and transmitting, by the target MN to a target secondary wireless communication node (SN), a first message to inform the target SN about a type of SN addition or change procedure to perform the handover request, wherein the first message causes the target SN to send a second message to the target MN to inform the target MN of one or more configured primary secondary (PSCells).

Abstract: A method includes receiving a first radio resource control (RRC) message including at least one of a conditional handover (CHO) configuration and a conditional primary secondary cell addition or change (CPAC) configuration. The CHO configuration includes a CHO configuration index, a CHO candidate cell configuration, and a CHO execution condition. The CPAC configuration includes a CPAC configuration index, a CPAC candidate cell configuration, and a CPAC execution condition. The method includes selecting, responsive to receiving the first RRC message and based on at least one of the CHO execution condition and the CPAC execution condition, a special cell (SpCell) of a wireless communication node to perform a random access procedure (RAP); and transmitting, to the wireless communication node, a second RRC message to inform the wireless communication node that the wireless communication device selected the SpCell to perform the RAP.

Abstract: Disclosed is a method for handling a radio link failure, including: a User Equipment (UE) in dual-connectivity configuration receiving a first configuration message; when a failure occurs in a first radio link of the UE, sending a Radio Resource Control (RRC) connection re-establishment request; and, in an RRC connection re-establishment process, when the UE detects that no failure occurs in a second radio link, performing data transmission through the second radio link. Also disclosed are another four methods, user equipments, base stations and storage mediums for handling a radio link failure.

Abstract: Systems and methods for wireless communications are disclosed herein. In one embodiment, a master node (MN) determines that a candidate target PScell/SCG in a candidate target secondary node (SN) needs to be released, canceled, or deleted. The candidate target SN is involved in a conditional SN addition or change multi-RAT dual connectivity (MR-DC) procedure of a wireless communication device. The MN and a source SN are currently configured to provide communication services to the wireless communication device. The MN requests to release, cancel, or delete the at least one candidate target PScell/SCG in the candidate target SN using a first signaling procedure.
