Abstract

A control apparatus configured to allow a communication device supporting a first frequency setting to enter a system providing a communications facility based on a second frequency setting, wherein the first frequency setting provides only a partial support for communications in the system is disclosed. The control apparatus may be co-operative with a second control apparatus. The second control apparatus is configured to determine based on frequency setting information received from the system if it is possible to transmit to the system based on the first frequency setting supported by the communication device.

Claims

1-40. -40. (canceled)

41. An apparatus comprising:

at least one processor and at least one memory including a computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to;

allow a communication device supporting a first frequency setting to enter a system providing a communications facility based on a second frequency setting,

wherein the first frequency setting provides only a partial support for communications in the system, and

wherein the first frequency setting provides support for communication on at least one frequency band, and the second frequency setting defines communications on at least one different frequency band.

42. An apparatus in accordance with claim 41 further configured to send frequency setting information.

43. An apparatus in accordance with claim 41, wherein the second frequency setting defines communications on a main frequency band and at least one additional frequency band.

44. An apparatus in accordance with claim 41, wherein the first frequency setting and the second frequency setting comprise radio frequency requirements for relevant radio frequency bands.

45. An apparatus in accordance with claim 42, wherein the frequency setting information comprises an indication of at least one of a frequency band and at least one additional frequency band provided by the system.

46. An apparatus in accordance with claim 41, wherein the apparatus is further caused to:

receive a transmission from the communication device, and

determine the level of support provided by the communication device for the second frequency setting based on the received transmission and to control communications by the communication device based on determination.

47. An apparatus in accordance with claim 46, wherein the apparatus is further caused to:

receive the transmission on a random access channel and determine the frequency bands supported by the communication device based on the received transmission.

48. An apparatus in accordance with claim 46, wherein the apparatus is further caused to decide on limitations on the communication device after determining capabilities thereof based on the received transmission.

49. An apparatus in accordance with claim 46, wherein the apparatus is further caused to control transmission scheduling based on the determination.

50. An apparatus in accordance with claim 49, wherein the apparatus is further caused to:

at least one of use a limited channel range, allocate resource blocks that are away from potential blocking signals, avoid use of band edges, and allocate frequency or frequencies that is/are away from critical emission area or areas.

51. An apparatus in accordance with claim 41, wherein the apparatus is further caused to use different sets of channel numbers for different communication devices.

52. An apparatus comprising:

at least one processor and at least one memory including a computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to;

determine based on frequency setting information received from a system providing a communications facility if it is possible to transmit to the system based on a first frequency setting supported by the communication device,

wherein the system provides the communications facility based on a second frequency setting and the first frequency setting provides only a partial support for communications in the system, and

wherein the first frequency setting provides support for communication on at least one frequency band, and the second frequency setting defines communications on at least one different frequency band.

53. An apparatus in accordance with claim 52, wherein the second frequency setting defines communications on a main frequency band and at least one additional frequency band.

54. An apparatus in accordance with claim 52, wherein the first frequency setting and the second frequency setting comprise radio frequency requirements for relevant radio frequency bands.

55. An apparatus in accordance with claim 52, wherein the frequency setting information comprises an indication of at least one of a frequency band provided by the system and at least one additional frequency band provided by the system.

56. An apparatus in accordance with claim 52, wherein the apparatus is further caused to:

determine based on the frequency setting information that at least one frequency band provided by the system is supported by the communication device, and

allow transmission on a random access channel to the system in response to such determination.

57. A method comprising:

receiving from a system frequency setting information at a communications device supporting a first frequency setting, wherein the system provides a communications facility based on a second frequency setting and the first frequency setting provides only a partial support for communications in the system; and

determining based on the frequency setting information if sending from the communication device to the system is possible,

wherein the first frequency setting provides support for communication on at least one frequency band, and the second frequency setting defines communications on at least one different frequency band.

58. A method in accordance with claim 57, wherein the second frequency setting defines communications on a main frequency band and at least one additional frequency band.

59. A method in accordance with claim 57, wherein the frequency setting information comprises an indication of at least one of a frequency band provided by the system and at least one additional frequency band provided by the system.

60. A method in accordance with claim 57, comprising transmitting a transmission on a random access channel to the access system in response to determining based on the received information that at least one frequency band provided by the system is supported by the communication device.
