METHOD OF CONFIGURING RADIO CONNECTION IN MULTIPLE CELL SYSTEM
First Claim
1. A method of configuring a radio connection in a multiple cell system, the method comprising:
- 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.
