Abstract
An OFDMA communication system includes a plurality of terminals, with at least one of the terminals including at least one type of multi-user decoder adapted to decode a signal intended for the at least one terminal received on a subchannel of the system and adapted to decode at least a portion of an interfering signal received on the subchannel. The system also includes a plurality of base stations. Each of the base stations may be in communication with others of the base stations for exchanging information about data throughput for particular terminals in cells of the system using particular subchannels in the cells. Each of the base stations assigns the subchannels to terminals in the cell of the base station so as to maximize data throughput in the entire system.

A method comprising:
- receiving a signal intended for a terminal of an Orthogonal Frequency Division Multiplexing Access (OFDMA) wireless communication system on a subchannel of said OFDMA system;
- receiving, by said terminal, an interfering signal on said subchannel;
- decoding at least a portion of said interfering signal;
- and
- using the decoded portion of said interfering signal to decode said intended signal.
An OFDMA terminal comprising:
- means for receiving a signal intended for said terminal and at least one interfering signal on a subchannel of an OFDMA wireless communication system;
- and
- at least one multi-user decoder adapted to decode said intended signal and at least a portion of said interfering signal.
A method comprising:
- overlapping use of a subchannel used by a cell of an OFDMA wireless communications system with use of said subchannel by at least one other cell of said OFDMA system so as to cause interfering signals using the same subchannel in one of said cells to overlap with a signal intended to be received by at least one terminal using said subchannel in the one cell.
An OFDMA communication system comprising:
- a plurality of base stations overlapping use of a subchannel used by a cell of an OFDMA wireless communications system with use of said subchannel by at least one other cell of said OFDMA system, such that interfering signals using a same subchannel in one of said cells overlaps with a signal intended to be received by at least one terminal using said subchannel in the one cell.
