Abstract
A method for distributing timing information in a radio communication system comprising: a network including a plurality of base stations, each capable of transmitting and receiving radio communication signals to and from a respective coverage area, and including a first base station and one or more neighboring base stations whose coverage areas neighbor the coverage area of the first base station; and a first mobile station capable of receiving signals from the first base station; the method comprising: estimating the differences in timing between those base stations; and transmitting indications of those differences in timing to the first mobile station.
Claims25
A method for distributing timing information in a radio communication system comprising:
- a network including a plurality of base stations, each capable of transmitting and receiving radio communication signals in at least a first mode to and from a respective coverage area in at least a first communication network, and including a first base station and one or more neighbouring base stations whose coverage areas neighbour the coverage area of the first base station;
- and
- a first mobile station capable of receiving signals from the first base station;
- the method comprising:
- estimating the differences in timing between those base stations;
- and
- transmitting indications of those difference in timing and transmitting indications of the accuracy of those differences to the first mobile station.
A radio communication system comprising:
- a network including a plurality of base stations, each being capable of transmitting and receiving radio communication signals to and from a respective coverage area, and having a first base station and one or more neighbouring base stations whose coverage areas neighbour the coverage area of the first base station;
- and a first mobile station capable of receiving signals from the first base station;
- wherein:
- the system comprises a timing estimator for estimating the difference in timing between the said at least two base stations and transmitting that indication to the network;
- and
- the network is capable of transmitting an indication of the difference in timing and the accuracy of that difference to the first mobile station.
A base station for a radio communication system comprising a network including a plurality of base stations, each being capable of transmitting and receiving radio communication signals to and from a respective coverage area, there being one or more neighbouring base stations whose coverage areas neighbour the coverage area of the said base station, the said base station comprising:
- a radio communication device for communicating with a first mobile station;
- a memory for receiving timing difference information indicating the differences in timing between the base station and the neighbouring base stations;
- and
- a memory for receiving information indicating an estimate of the accuracy of the timing difference information;
- and
- transmission control apparatus for causing the radio communication device to transmit the timing difference and accuracy of this difference information to the first mobile station.
