METHOD OF CONFIGURING RADIO CONNECTION IN MULTIPLE CELL SYSTEM

摘要

A method of configuring a radio connection in a multiple cell system is provided. The method includes configuring a first radio connection between a user equipment (UE) and a primary base station (BS) and a second radio connection between the UE and a secondary BS based on a cooperative transmission configuration in which a plurality of BSs transmit the same data to the UE, receiving first channel state regarding the first radio connection and second channel state regarding the second radio connection from the UE, releasing at least one radio connection of the first radio connection and the second radio connection, the at least one radio connection having a worse channel state than a threshold, transmitting to the UE, a new cooperative transmission configuration changed by the release of the at least one radio connection, and receiving a layer reconfiguration complete message indicating completion of layer reconfiguration based on the new cooperative transmission configuration.
