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

1-34. -34. (canceled)

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

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

and

listening by a base station while not transmitting, to potential messages coming from other base stations, wherein the timeslots are based on monitoring and adapting to time slot patterns of neighbouring base stations.

36. A method as claimed in claim 35 wherein said information pertains to co-ordination of said base stations.

37. A method as claimed in claim 35, wherein said information are over-the-air communication (OTAC) messages.

38. A method as claimed in claim 35, wherein said base stations are part of a cellular communication network.

39. A method as claimed in claim 38, wherein the cellular communication network is an autonomous network.

40. A method as claimed in claim 35, wherein said timeslots are regularly spaced.

41. A method as claimed in claim 35, wherein the timeslots are a function of system frame number (SFN).

42. A method as claimed in claim 35, wherein if a base station has a co-ordination message to be transmitted, transmitting the information in a first coming timeslot.

43. A method as claimed in claim 42, wherein the information is retransmitted automatically.

44. A method of co-ordinating communication between a plurality of base stations in a communication system, 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.

45. A method as claimed in claim 44, wherein the information is retransmitted after N timeslots periods wherein N is based on base station ID.

46. 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; and

to listen to messages from other base stations while the base station is not transmitting, wherein the timeslots are based on monitoring and adapting to time slot patterns of neighbouring base stations.

47. A base station as claimed in claim 46, wherein said co-ordination information is information pertaining to co-ordination of a plurality of base stations in a communication system.

48. A base station as claimed in claim 46, wherein said information is over-the-air communication (OTAC) messages.

49. A base station as claimed in claim 46, wherein the base station is part of an autonomous network.

50. A base station as claimed in claim 46, wherein timing of the timeslots is a function of system frame number (SFN).

51. 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.

52. A base station as claimed in claim 51, wherein said information is over-the-air communication (OTAC) messages.

53. A base station as claimed in claim 51, wherein timing of the timeslots is a function of system frame number (SFN).

54. A base station as claimed in claim 51, wherein the base station is part of an autonomous network.
