Abstract
A method of allocating bandwidth is provided which involves for each sector of a plurality of sectors in a cell, using a respective subset of a total bandwidth; wherein for any two adjacent sectors, the respective subsets only partially overlap. A scheduling method is provided which involves for each sector, scheduling users for transmission on the respective subset of the total bandwidth by: for a given transmitter, allocating a respective fraction of capacity associated with the available bandwidth to each of at least two users selected from a plurality of users by performing an optimization for a selected scheduler design, the optimization selecting the at least two users and the optimization determining for each user the respective fraction of capacity; generating and transmitting a signal in which each of the at least two users has the respective fraction of capacity.
