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: A clear channel detection method and node device are described. The method includes: if a node device performs a CCA detection for the first time and finds that a full bandwidth of an unlicensed carrier channel is in a busy state, the node device divides the full bandwidth of the unlicensed carrier channel into two or more sub-bandwidths for the first time according to a preset division manner; if the node device performs the CCA detection again and finds that all sub-bandwidths are in the busy state, the node device divides each of the divided sub-bandwidths into two or more sub-bandwidths for the second time according to the preset division manner, and continues to perform CCA detection until the CCA detects that any sub-bandwidth is in a clear state, or the number of CCA cycle detections is up to a maximum value, then exits from the CCA cycle detections.

Abstract: Management and coordination of sensing may be performed through a wireless sensing session management function (S-SMF) that provides policies, configuration data, or sensing assistant data related to a wireless sensing session. S-SMF may be in independent and decoupled from a session management function (SMF), which provides communication session related policies and configuration data. The S-SMF manages the wireless sensing session and the SMF manages other communication sessions. Additional functions may include a Sensing Anchor Function (AMF) configured for controlling a wireless sensing session, and a Sensing Data Storage Function (S-UPF) configured for storing wireless sensing result data from the wireless sensing session.

Abstract: An integrated wireless sensing and communication (ISAC) system may allow for a radio access network (“RAN”) node to improve the sensing. There may be a secondary sensing radio link (S-S-RL) for additional sensing functionality. The sensing signal can be used by the RAN node and/or the UE for detecting objects along a radio path between the RAN node and UE to improve the wireless communication through RL. The S-S-RL may be added in a single connectivity system or may be modified in a dual connectivity system. In order to maximize the sensing collaboration benefits among RAN nodes, the S-S-RL can assist communication or assist sensing.

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: The present disclosure describes methods, system, and devices for negotiating minimization of drive test (MDT) parameters of user equipment (UE). One method includes receiving, by a radio access network (RAN) node, a first message from a core network (CN) or an operation and maintain system (OAM), the first message comprising at least one of a negotiable or a non-negotiable MDT configuration parameter; in response to receiving the first message, determining whether the UE is suitable to carry out a MDT task corresponding to the first message; in response to the determining that the UE is suitable to carry out the MDT task corresponding to the first message, sending a second message to the UE; receiving a third message from the UE, the third message comprising at least a value suggested by the UE for the negotiable MDT configuration parameter; and sending a fourth message to the CN or the OAM.

Abstract: Presented are systems, methods, apparatuses, or computer-readable media for data forwarding in centralized unit (CU) and distributed unit (DU) split architectures. A DU may receive, from a CU, context information for forwarding of data from a wireless communication device that is in radio resource control (RRC) inactive state. The DU may receive, from the wireless communication device, the data from the wireless communication device that is in RRC inactive state. The DU may process the data according to the context information. The DU may send, to the CU, the processed data according to the context information.

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