Abstract
The invention is directed to a mobile communications system having improved spectral efficiency. The invention is further directed to methods and apparatus to achieve this improved spectral efficiency. In the mobile communications system communication with a plurality of mobile terminals is provided by a base station. Within the system terminals are adapted to communicate with one or more adjacent similar terminals to establish groups of terminals, called micro-cells. Each terminal within a micro-cell receives signals from the base station and then performs a first processing step on these signals. These processed signals are shared with all the other terminals within the micro-cell. Each terminal then performs a second processing step on the information it has received from all the other terminals within the micro-cell which enables it to derive a signal intended for reception by that terminal. The technique is applicable to both the uplink (user to base station) and the down link (base station to user) and also to peer to peer (user to user) communication.
