Patent ID: 8913538

Claim:
A method of receiving multimedia broadcast/multicast service (MBMS) information by a user equipment (UE) in a wireless communication system, the method comprising: transmitting, to a first cell, MBMS capability information and carrier aggregation capability information, the MBMS capability information indicating whether the UE supports a reception of the MBMS information, the carrier aggregation capability information indicating whether the UE supports the reception of the MBMS information using a carrier aggregation scheme; receiving MBMS cell information on a second cell from the first cell over a first channel, the MBMS cell information including an MBMS cell identifier for identifying that the second cell is a cell providing a MBMS, frequency information for transmitting the MBMS of the second cell, and information indicating which MBMS session starts, changes, or ends, wherein the first channel is a physical downlink control channel (PDCCH), and wherein the PDCCH is masked by an MBMS radio network temporary identifier (M-RNTI) indicating that the second cell provides the MBMS information; and receiving the MBMS information from the second cell over a second channel based on the received MBMS cell information, the MBMS information including at least one of control information on the MBMS, service information on the MBMS and traffic data of the MBMS, wherein the first cell does not provide the MBMS, and the second cell provides the MBMS, wherein the first cell and the second cell are co-located and constitute a hierarchical cell structure, wherein a first frequency band allocated to the first cell is different from a second frequency band allocated to the second cell, the first frequency band and the second frequency band being transmitted by a carrier aggregation, and wherein the MBMS information is received in a discontinuous reception (DRX) duration in which a unicast service is not transmitted from the first cell.
