Abstract
A method of communicating data in a wireless telecommunications system between plural base stations and plural terminal devices using plural Orthogonal Frequency Division Multiplex, OFDM, sub-carriers spanning a first frequency bandwidth. The method includes: communicating data between a first base station and a first terminal device using a first group of the OFDM sub-carriers distributed across the first frequency bandwidth, communicating data between a second base station, geographically separated from the first base station, and a second terminal device using a second group of the OFDM sub-carriers distributed across a second frequency bandwidth, and communicating control-plane data between the first base station and the first terminal device using a combination of the first and second groups of the OFDM sub-carriers. Guard regions may be provided in the frequency domain between frequencies of transmissions associated with the first base station and frequencies of transmissions associated with the second base station.
