ABSTRACT:
A transmission method for use in a multi-hop wireless communication system is provided. The method includes, for two apparatuses having overlapping transmission coverage areas, one of the two said apparatuses being an intermediate apparatus, transmitting a first transmission signal from a first one of those apparatuses in a first transmission window of a particular transmission interval and transmitting a second transmission signal from the second one of those apparatuses in a second transmission window of the particular transmission interval but not in said first transmission window, so that a communication apparatus located in the coverage areas of both the first and second apparatuses can receive said first transmission signal substantially without interference from said second transmission signal.
