1. A mobile communications system in which communication with a plurality of mobile terminals is provided by a base station, wherein said terminals are adapted each to communicate with one or more adjacent similar terminals to establish ad-hoc groups of terminals, each said group functioning cooperatively as a micro-cell for communications purposes, wherein each terminal in a said group is arranged to perform a first processing step on signals received from the base station, to exchange directly with the other terminals of the group transmission related signal information derived from said first processing step, and to perform a second spatial processing step utilizing exchanged transmission related signal information received from other terminals of the group so as to derive, from the received signals, a signal intended for reception by that terminal, and wherein the number of terminals within a said group maximizes the spectral efficiency of the system.
