SYSTEM AND METHOD FOR DETERMINING A TRANSMIT TIMING FOR COMMUNICATION IN A RADIO COMMUNICATION SYSTEM
First Claim
1. A method for determining a transmission timing for communication in a radio communication system, said radio communication system comprising a first radio transceiver, wherein communication from a user entity in a coverage area of said first radio transceiver is carried out in a communication link between said user entity and said first radio transceiver in a synchronized manner, and the method comprises:
- in said user entity, at a first point in time;
determining a transmission timing for transmissions from said user entity to said first radio transceiver in said communication link;
determining a representation of a first position of said user entity in relation to said first radio transceiver and at least a second and a third radio transceiver; and
in said user entity, at a second point in time, subsequent to said first point in time;
determining a representation of a second position of said user entity in relation to said first, second and third radio transceivers; and
adjusting said transmission timing based on a difference of said first position and said second position.

Abstract
A method for determining a transmission timing is provided. The method includes steps of, at a first point in time, determining a first transmission timing for transmissions from a user entity to a first radio transceiver, and determining a representation of a first position of the user entity in relation to the first radio transceiver and at least a second and a third radio transceiver. The method further includes, at a second point in time, subsequent to the first point in time, determining a representation of a second position of the user entity in relation to the first, second and third radio transceivers, and adjusting the transmission timing based on a difference of the first position and the second position.

16. A system for determining a transmission timing for communication in a radio communication system comprising:
-
a first radio transceiver, wherein communication from a user entity in a coverage area of said first radio transceiver is carried out in a communication link between said user entity and said first radio transceiver in a synchronized manner; a user entity configured to, at a first point in time; determine a transmission timing for transmissions from said user entity to said first radio transceiver in said communication link; determine a representation of a first position of said user entity in relation to said first radio transceiver and at least a second and a third radio transceiver; and at a second point in time, subsequent to said first point in time; determine a representation of a second position of said user entity in relation to said first, second and third radio transceivers; and adjust said transmission timing based on a difference of said first position and said second position. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A user entity for use in a system for determining a transmission timing for communication in a radio communication system comprising:
-
a radio communication system comprising a first radio transceiver, wherein communication from a user entity in a coverage area of said first radio transceiver is carried out in a communication link between said user entity and said first radio transceiver in a synchronized manner; the user entity is configured to, at a first point in time; determine a transmission timing for transmissions from said user entity to said first radio transceiver in said communication link; determine a representation of a first position of said user entity in relation to said first radio transceiver and at least a second and a third radio transceiver; and at a second point in time, subsequent to said first point in time; determine a representation of a second position of said user entity in relation to said first, second and third radio transceivers; and adjust said transmission timing based on a difference of said first position and said second position.
