Abstract

In accordance with the exemplary embodiments of the invention, as described herein, there is at least a method, apparatus, and a computer program code to receive signaling from an access node of a wireless network that uses component carrier aggregation, the signaling including an identification of a plurality of component carriers and a priority associated with individual ones of the component carriers, and select one of the component carriers to camp on when in an idle mode. Further, in accordance with the exemplary embodiments of the invention, there is transmitting signaling from an access node of a wireless network that uses component carrier aggregation, the signaling including an identification of a plurality of component carriers and a priority associated with individual ones of the component carriers, and receiving a random access channel corresponding to a component carrier selected by a user equipment in accordance with the transmitted signaling.

Claims

1-30. -30. (canceled)

31. A method, comprising:

receiving signaling from an access node of a wireless network that uses component carrier aggregation, the signaling comprising an identification of a plurality of component carriers and a priority associated with individual ones of the component carriers; and

selecting one of the component carriers to camp on when in an idle mode.

32. The method according to claim 31, further comprising using a random access channel corresponding to the selected component carrier.

33. The method according to claim 31, wherein the signaling is received from a broadcast channel.

34. The method according to claim 31, wherein the signaling is received in a system information block.

35. The method according to claim 34, wherein the system information block is SysteminformationBlock Type 5.

36. The method according to claim 31, wherein the signaling is dedicated signaling.

37. The method according to claim 31, wherein the priority is one of explicitly indicated or implicitly indicated.

38. The method according to claim 31, wherein receiving is performed by a first type of user equipment capable of concurrent operation with a plurality of component carriers, and wherein the priorities associated with individual ones of the component carriers are one of aligned with those of any component carriers used by a second type of user equipment not capable of concurrent operation with a plurality of component carriers, or are independent of any component carriers used by the second type of user equipment.

39. The method according to claim 31, wherein the priority is determined in accordance with an order in which the component carriers are identified.

40. A computer readable medium storing a program of instructions, execution of which by a processor configures an apparatus to perform actions comprising at least:

receiving signaling from an access node of a wireless network that uses component carrier aggregation, the signaling comprising an identification of a plurality of component carriers and a priority associated with individual ones of the component carriers; and

selecting one of the component carriers to camp on when in an idle mode.

41. An apparatus comprising:

at least one processor; and

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

receive signaling from an access node of a wireless network that uses component carrier aggregation, the signaling comprising an identification of a plurality of component carriers and a priority associated with individual ones of the component carriers; and

select one of the component carriers to camp on when in an idle mode.

42. The apparatus according to claim 41, further comprising the at least one memory and the computer program code are configured, with the at least one processor to cause the apparatus to use a random access channel corresponding to the selected component carrier.

43. The apparatus according to claim 41, wherein the signaling is received from a broadcast channel.

44. The apparatus according to claim 41, wherein the signaling is received in a system information block.

45. The apparatus according to claim 44, wherein the system information block is SysteminformationBlock Type 5.

46. The apparatus according to claim 41, where the signaling is dedicated signaling.

47. The apparatus according to claim 41, wherein the priority is one of explicitly indicated or implicitly indicated.

48. The apparatus according to claim 41, wherein the priority is determined in accordance with an order in which the component carriers are identified.

49. An apparatus, comprising:

at least one processor; and

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

transmit signaling from an access node of a wireless network that uses component carrier aggregation, the signaling comprising an identification of a plurality of component carriers and a priority associated with individual ones of the component carriers; and

receive a random access channel corresponding to a component carrier selected by a user equipment in accordance with the transmitted signaling.

50. The apparatus according to claim 49, wherein the signaling is transmitted in a system information block.
