The method includes: receiving a handover request message sent by a source base station or a core network node; sending a first message, according to the handover request message, to a second target base station to notify the second target base station that a handover of part or all of a service of a user equipment to the second target base station is to be performed; and sending a handover request acknowledge message to the source base station or the core network node to notify the source base station or the core network node to hand over the user equipment to at least one target cell of the first target base station and/or at least one target cell of the second target base station. The present application realizes a multi-cell handover.

A relay device includes, a storage configured to receive distributed video data, and store the received video data, a predictor configured to predict a communication disabled period in which the terminal device is disabled to perform communication, and a transmission controller configured to start transmission of the stored video data to the terminal device after a start delay period elapses from the start of the storing, wherein the transmission controller transmits the video data, which is to be played by the terminal device in a communication enabled period in which the terminal device is predicted to be enabled to perform communication and in the communication disabled period following the communication enabled period, to the terminal device in the communication enabled period.

A method of performing cell selection, by a terminal, in a wireless communication system is provided. The method includes receiving a control message including configuration information for a radio resource control (RRC) inactive state, entering the RRC inactive state based on the configuration information; performing cell selection, and in response to a suitable cell not being found and an acceptable cell being found in the cell selection, entering a RRC idle state.

This disclosure relates generally to wireless communications and, more particularly, to systems and methods for reselection or redirection among cells of different geographic coverage. In one embodiment, a method performed by a communication device includes: receiving configuration information from a first communication node, wherein the first communication node is part of a first cell or a first carrier; determining a second communication node based on the configuration information, wherein the second communication node is part of a second cell or a second carrier; and initializing a random access procedure or continuing with the random access procedure on the second communication node.

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of enabling a successful Mobility Robustness Optimization analysis for primary secondary cell (PSCell) changes.
