Apparatuses and methods in a communication system are provided. A method comprises receiving from network instructions of how to control multi-user multiple input multiple output connections maintained by one or more radio access nodes, the connections utilising one or more slices. One or more radio access nodes perform, based at least in part on the received network instructions, multi-user pairing of terminal devices of the same or different slices, and determine, based at least in part on the received network instructions, slice-based quota taking multi-user pairing and interference arising from paired allocations into account.

A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes generating a report, and transmitting the report to an access node in the wireless communication system, wherein the report is generated in or after an Internet Protocol (IP) Multimedia Subsystem (IMS) voice related process of the UE.

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Provided is a method performed by a terminal in a wireless communication system that includes receiving a radio resource control (RRC) message including information associated with a deactivation of a secondary cell group (SCG), and resetting a medium access control (MAC) of the SCG based on the RRC message, with a timing alignment timer (TAT) associated with the SCG not being stopped for resetting the MAC of the SCG.

A method and apparatus for providing a cell group activation or deactivation service in a wireless communication system are provided. The method includes a first base station transmitting, to a second base station, a request message associated with the dual access. The method includes receiving, from the second base station, a response message including configuration information related to a second cell group (SCG) for the dual access. The method includes identifying whether the response message includes information related to a state of the SCG. And the method includes transmitting, to a terminal, a radio resource control (RRC) message including the configuration information of the SCG and the information related to the state of the SCG, wherein the configuration information of the SCG includes information not to perform QoS flow remapping on data radio bearer associated with the SCG in case that the SCG is inactive or the information related to the state of the SCG includes a request deactivating the SCG.

A network device may receive an indication of movement of a user device, associated with multiple packet data unit (PDU) sessions, from a first radio access network (RAN) to a second RAN, and may maintain, based on the indication, a particular PDU session, of the multiple PDU sessions, associated with a default flow. The network device may release, based on the indication, the multiple PDU sessions other than the particular PDU session, and may handle the multiple PDU sessions, other than the particular PDU session, in accordance with a handling option.

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for GNSS validity reporting in NTNs. A UE may transmit, to a network entity, a report of a validity duration for GNSS tracking information. The GNSS tracking information may be associated with an NTN including the UE and the network entity. The report may include an indication of a remaining time period of the validity duration based on a threshold. The UE may switch to an RRC idle mode based on the report of the validity duration. The RRC idle mode may be switched to after an expiration of the remaining time period of the validity duration or based on an RRC release message received from the network entity.
