  • Publication number: 20080045238
    Abstract: 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.

  • Publication number: 20080043710
    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.

  • Publication number: 20080043712
    Abstract: 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.

  • Publication number: 20080043816
    Abstract: A transmission method for use in a two-hop wireless communication system is provided. The system includes a source apparatus, a destination apparatus and an intermediate apparatus. The source apparatus is operable to transmit information along two links forming a communication path extending from the source apparatus to the destination apparatus via the intermediate apparatus. The intermediate apparatus is operable to receive information from the source apparatus and to transmit the received information to the destination apparatus. 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.

  • Patent number: 6006918
    Abstract: A collapsible storage container has four walls hingedly connected with depending L-shaped hooks. The walls are moveable between a container configuration in which the L-shaped hooks captively engage a pallet which forms the base of an enclosure defined by the walls and a collapsed configuration in which the walls overlay one another in a substantially parallel arrangement. A roof is connected by hinges to one of the walls and is moveable between a closed position in which lugs engage an opposite wall and a storage position in which the roof is substantially parallel to the wall.
