    Abstract: Presented are systems and methods for dynamically changing multicast service delivery between multicast and unicast with service continuity. A wireless communication device may receive multicast radio resource configuration information from a network. The wireless communication device may configure, according to the multicast radio resource configuration information, an air interface protocol stack of the wireless communication device. The wireless communication device may receive data of a multicast service according to the multicast radio resource configuration information.

    Abstract: A system and method for managing Multimedia Broadcast Multicast Service (MBMS) continuity. The system and method include transmitting, by a wireless communication device through a first distributed unit (DU) of a wireless communication node to a central unit (CU) of the wireless communication node, a first message. The first DU corresponds to a first subset of a plurality of MBMS services of the CU. The first message indicates a second subset of the plurality of MBMS services that corresponds to a second DU of the wireless communication node. The system and method include receiving, by the wireless communication device from the CU in response to transmitting the first message, a second message including MBMS scheduling information. The system and method include performing, by the wireless communication device, a handover procedure from the first DU to the second DU.

    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: This disclosure above describes a method, a device, and a system for encrypting/decrypting physical channels in a wireless communication network. Among various embodiments are: pre-allocating a key, dynamically granting a key, encrypting the physical channel based on key in various levels, dividing the spectrum into two categories, or dividing a network into an initial access network and a private network. In one embodiment, a method for physical channel encryption is disclosed. Performed by a UE, the method may include obtaining a first key for decrypting a first physical channel, the first physical channel being encrypted; and decrypting the first physical channel based on the first key to obtain a signal or data transmitted by a first network element, the signal or the data being carried in the first physical channel.

    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.
