This application provides a communication method and a communications device. The method includes: A first device receives a first message sent by a second device. The first message is used to indicate a bearer configuration of a bearer of the first device and an initial status of the bearer configuration, and the bearer configuration includes a first bearer configuration and/or a second bearer configuration. The first device determines the bearer configuration and the initial status of the bearer configuration based on the first message. According to the technical solutions in embodiments of this application, a bearer configuration of a terminal device and an initial status of the bearer configuration of the terminal can be indicated.

Methods and Systems for modifying or releasing a Multicast/Broadcast (MB) session for delivery of MB Data to a plurality of Electronic Devices (EDs) connected to a (Radio) Access Network (R)AN node is disclosed. The method includes receiving one or more triggers, and instructing the various network functions and (R)AN nodes to modify (or release) the MB session dependent on the received trigger.

A wireless device receives configuration parameters indicating: a first cell carries scheduling information for first packets received via the first cell; and a second cell carries scheduling information for second packets transmitted via the first cell. A downlink control information (DCI) for transmission via the first cell is received. A determination is made whether the DCI is for uplink transmission or downlink transmission. Based on the determining, a deactivation timer of the second cell is restarted or not restarted. In response to the deactivation timer of the second cell expiring, the second cell is deactivated.

There is provided mechanisms for beam related statistics aided resumed beamformed communication with a terminal device. A method is performed by a radio access network node. The method comprises providing network access to the terminal device by, in a first set of beams, performing beamformed communication with the terminal device until the terminal device leaves radio resource control (RRC) connected mode. The method comprises storing beam related statistics of the beamformed communication. The method comprises providing resumed network access to the terminal device by, in a second set of beams, performing resumed beamformed communication with the terminal device upon the terminal entering RRC connected mode. How to perform the resumed beamformed communication is based on the beam related statistics.

The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a session management function (SMF) in a mobile network is provided. The method may include receiving an information on a multicast/broadcast service protocol data unit (MBS PDU) session with a user equipment (UE) in an idle state, the MBS PDU session being in an active state, and transmitting, to an access and mobility management function (AMF), an information indicating that the UE in the idle state joins the MBS PDU session. The information indicating that the UE joins the MBS PDU session is used for a radio resource control (RRC) connection reconfiguration with the UE in the idle state.
