Patent ID: 8660050

Claim:
A method of transmitting multicast broadcast service (MBS) data in a wireless communication system using fractional frequency reuse (FFR), the method comprising: allocating a first network common zone, which includes a plurality of contiguous subcarriers and corresponds to radio resources for transmitting MBS data, at a left edge of a full available frequency region, wherein a left edge of the first network common zone is contiguous to left system guard subcarriers, and a right edge of the first network common zone is contiguous to first guard subcarriers; allocating a second network common zone, which includes a plurality of contiguous subcarriers and corresponding radio resources for transmitting MBS data, at a right edge of the full available frequency region, wherein a right edge of the second network common zone is contiguous to right system guard subcarriers, and a left edge of the second network common zone is contiguous to second guard subcarriers; and transmitting the MBS data through at least one of the first network common zone and the second network common zone.
