Abstract

A method of co-ordinating communication between a plurality of base stations in a communication system, comprising designating timeslots where said base stations receive and/or transit co-ordination messages to each other. The system may be an autonomous cellular system and the timeslots may be regularly spaced.

Claims

1. A method of co-ordinating communication between a plurality of base stations in a communication system, the method comprising:

at least one of designating and synchronising timeslots where said base stations receive and/or transmit information to each other,

wherein the information is retransmitted after N timeslots periods, where N is an integer and is different from and varies between different base stations.

2. A method as claimed in claim 1, wherein the information is retransmitted after N timeslots periods wherein N is based on base station ID.

3. A base station comprising:

at least one antenna for wireless communication, and

a data processing entity connected with a memory that stores computer software, where execution of the computer software by the data processing entity results in the base station being configured to receive and/or transmit information to or from one or more other base stations during at least one of designated and synchronised timeslots,

wherein the information is retransmitted after N time-slot periods, where N is an integer and is different from and varies to other base stations.

4. A base station as claimed in claim 3, wherein said information is over-the-air communication (OTAC) messages.

5. A base station as claimed in claim 3, wherein timing of the timeslots is a function of system frame number (SFN).

6. A base station as claimed in claim 3, wherein the base station is part of an autonomous network.
