1。 In this paper, a chunk is regarded as the minimum
granularity of the radio resource allocation unit, which is
defined as a collection of consecutive subcarriers over a
defined time period. By using intercell coordination, our
proposed scheme thrives to maximize throughput on allocated
chunks considering the rate requirements of the cell edge UTs.
In particular, any optimal or sub-optimal allocation scheme,
such as in [6], can exploit multiuser diversity to achieve
maximized sector throughput by optimally or sub-optimally
assigning best chunks to UTs. However, as the cell edge UTs
experience higher path-losses on the desired links and higher
interference from nearby cells, these scheduling schemes tend
to overlook such disadvantaged UTs. Therefore, interference
avoidance is crucial in order to offer minimum required data
rate to the cell edge UTs.
