Method and apparatus for communication using a plurality of cells in a wireless communication system
First Claim
1. A base station for cell configuration in a mobile communication system supporting carrier aggregation (CA), the base station comprising:
- a transceiver configured to transmit and receive signals; and
at least one processor configured to;
control transmitting configuration information for configuring a first cell allocated with a first component carrier (CC) to a terminal,transmit configuration information for adding a second cell allocated with a second CC to the terminal, andcommunicate with the terminal via the first CC of the first cell and the second CC of the second cell,wherein sectors of the first cell, each allocated with the same first CC, are set to a same physical cell identifier (PCID) and sectors of the second cell, each allocated with the same second CC, are set to PCIDs that are different from the same PCID set for the sectors of the first cell, andwherein the PCIDs set for the sectors of the second cell are different from each other.

Abstract
The present invention provides a cell configuration method of a base station in a mobile communication system supporting Carrier Aggregation (CA) which includes configuring a first cell consisting of at least two sectors formed with different antennas to a terminal, configuring a second cell consisting of at least two sectors formed with different antennas to the terminal, and communicating with the terminal through the first and second cells, wherein one of the first and second cells consists of sectors using same Physical Cell Identifier (PCID) and the other consists of sectors using different PCIDs.
