Abstract
A method for processing signals in a communications system comprising a first station and a plurality of second stations, said method comprising the steps of receiving at said plurality of second stations signals from said first station; sending said received signals to a designated one of said plurality of second stations; and processing in said designated second station the signals received by plurality of second stations to provide a single signal.
Claims19
A method for processing signals in a communications system comprising a first station, a plurality of second stations and a control node, said method comprising the steps of:
- providing the control node with information relating to a designated one of said second stations;
- providing at least one other of said plurality of second stations with said information from the control node associated with the designated one of said second stations;
- forming a connection between said designated one of said second stations and said at least one of said second stations using said information;
- receiving at said plurality of second stations signals from said first station;
- sending said received signals from said at least one other of plurality of second stations to the designated one of said plurality of second stations by said connection;
- and
- processing in said designated second station the signals received from said at least one other of plurality of second stations and the signals received at said designated second station to provide a single signal.
A method as claimed in any preceding claim, wherein said communication system comprises a fixed node.
A method as claimed in any preceding claim, comprising the step of setting up a connection between said designated second station and the first station before a connection is set up between the or each other second station.
A method as claim claimed in any preceding claim, comprising the step of setting up a connection between the designated second station and the or each other second station.
A method as claimed in any preceding claim, comprising the step of the designated second station sending data for the first station to the or each other second station, the designated second station and the or each other second station sending said data to said first station.
A method as claimed in any preceding claim, wherein said first station is a mobile station.
A method as claimed in any preceding claim, wherein said plurality of second stations are base stations.
A method as claimed in any preceding claim, wherein said processing step comprises combining said signals.
A communication system comprising a first station, a plurality of second stations and a control node, the control node being arranged to receive information relating to a designated one of said second stations, at least one other of said plurality of second stations being arranged to receive said information from the control node associated with the designated one of said second stations, each of said second stations being arranged to receive the same signals from the first station, the designated one of said second stations being arranged to receive from the at least one other of said plurality of second stations the signals received from the first station on a connection formed between said designated one of said second stations and said at least one of said second stations using said information, said designated one of said second stations comprising processing means for processing the signals received from said at least one other of plurality of second stations and the signals received at said designated second station.
A second station for use in a communication system comprising a first station, a plurality of second stations and a control node, each of said second stations being arranged to receive the same signals from the first station, said second station comprising:
- first means for providing the control node with information relating to the second station;
- second means for receiving the signals from the first station;
- third means for receiving from the or each other second station, on a connection formed between the or each other second station using the information relating to the second station, the signals received from the first station;
- and
- a processing means for processing the signals received by the third and second means to provide a signal.
