A transmission method for use in a multi-hop wireless communication system is provided. The system includes a source apparatus, a destination apparatus and two or more intermediate apparatuses. The system has access to a time-frequency format for use in assigning available transmission frequency bandwidth during a discrete transmission interval, said format defining a plurality of transmission windows within such an interval. Each window occupies a different part of that interval and has a frequency bandwidth profile within said available transmission frequency bandwidth over its part of that interval. Each said window is assignable for such a transmission interval to one of said apparatuses for use in transmission. The method for use in this system includes employing said format for one or more such transmission intervals to transmit information along at least three consecutive said links as a set of successive transmission signals, link by link, each said signal being transmitted in an available transmission window of said interval(s) and at least two of said signals being transmitted during the same said transmission interval such that said information is transmitted along said consecutive links in fewer transmission intervals than said number of consecutive links.
