摘要： A transmission method for use in a multi-hop wireless communication system is provided. The system includes a source apparatus, a destination apparatus and one or more intermediate apparatuses. The system has access to at least one predetermined transmission introduction sequence and also 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 being assignable for such a transmission interval to at least one of said apparatuses for use in transmission. The method includes, when transmitting a message with a preamble in a particular transmission interval, transmitting the preamble in a first transmission window of that transmission interval. Furthermore, the method includes transmitting the transmission introduction sequence in a second transmission window of that transmission interval other than the first transmission window preferably as control information for use by at least one said intermediate apparatus or the destination apparatus.

摘要： A wireless transmission method for use in a wireless communication system is provided. The system includes at least two communication apparatuses which may experience relative movement therebetween. One such communication apparatus is a source apparatus that is operable to transmit information to the destination apparatus, which is the other communication apparatus. The wireless transmission method includes, at two or more time instants, obtaining a measure of channel characteristics between the source apparatus and the destination apparatus. Furthermore, the method includes calculating a correlation factor between the at least two time-consecutive measures over time, and employing the correlation factor or a value derived therefrom as an estimate of relative movement between the source apparatus and the destination apparatus in determining a transmission parameter. Moreover, the method includes transmitting a transmission signal from the source apparatus to the destination apparatus using the determined parameter.
