Abstract

In accordance with an example embodiment of the present invention, an apparatus including 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 to, with the at least one processor, cause the apparatus to perform at least the following report a maximum supported radio frequency bandwidth, report a number of supported carriers, and receive data on non-adjacent carriers.

First claim

What is claimed is:

1. A method comprising:
reporting a maximum radio frequency bandwidth supported by a user equipment in a capability field of at least one uplink report message to a base station, via a wireless connection;
reporting, via a plurality of information elements in the capability field, a number of carriers within said maximum radio frequency bandwidth supported by the user equipment in said at least one uplink report message to the base station, each of said carriers being a portion of said maximum radio frequency bandwidth and having a corresponding one of an information element among the plurality of information elements, said carriers collectively not occupying all of said maximum radio frequency bandwidth, thereby creating at least one gap between carriers in said maximum radio frequency bandwidth, wherein each of the corresponding information elements has a corresponding carrier parameter and a collective quantity of the plurality of information elements indicates the number of carriers supported;
reporting, via a maximum gap size information element in the capability field separate from the plurality of information elements, a maximum gap size between non-adjacent carriers to the base station, said non-adjacent carriers being those separated from one another by said at least one gap, wherein said maximum gap size is equal to a difference between the maximum radio frequency bandwidth and a sum of the bandwidths of the portions of the maximum frequency bandwidth occupied by said carriers; and
receiving data in downlink from the base station on said non-adjacent carriers at the user equipment in accordance with the maximum radio frequency bandwidth, the number of carriers, and the maximum gap size reported to the base station,
wherein the method is performed by the user equipment.

2. The method of claim 1 , wherein reporting the maximum supported radio frequency bandwidth comprises reporting the maximum supported radio frequency bandwidth for each supported band.

3. The method of claim 1 , wherein reporting a number of supported carriers comprises reporting a number of supported carriers for each supported band.

4. A method comprising:
receiving at a base station in a capability field of at least one uplink report message a maximum radio frequency bandwidth supported by a user equipment, via a wireless connection;
receiving, via a plurality of information elements in the capability field, at the base station a number of carriers within said maximum radio frequency bandwidth supported by the user equipment in said at least one uplink report message, each of said carriers being a portion of said maximum radio frequency bandwidth and having a corresponding one of an information element among the plurality of information elements, said carriers collectively not occupying all of said maximum radio frequency bandwidth, thereby creating at least one gap between carriers in said maximum radio frequency bandwidth, wherein each of the corresponding information elements has a corresponding carrier parameter and a collective quantity of the plurality of information elements indicates the number of carriers supported;
receiving, via a maximum gap size information element in the capability field separate from the plurality of information elements, at the base station a maximum gap size between non-adjacent carriers from the user equipment, said non-adjacent carriers being those separated from one another by said at least one gap, wherein said maximum gap size is equal to a difference between the maximum radio frequency bandwidth and a sum of the bandwidths of the portions of the maximum frequency bandwidth occupied by said carriers;
allocating data on said non-adjacent carriers for a downlink transmission to the user equipment, wherein the non-adjacent carriers are determined based at least in part on the received maximum radio frequency bandwidth supported by the user equipment, the received number of carriers supported by the user equipment, and the maximum gap size; and
sending the data to the user equipment on the non-adjacent carriers in the downlink transmission,
wherein the method is performed by the base station.

5. The method of claim 4 , wherein the non-adjacent carriers are further determined based at least in part on the received maximum supported radio frequency bandwidth and the received number of supported carriers and the received maximum gap size between non-adjacent carriers.

6. The method of claim 4 , wherein receiving a maximum supported radio frequency bandwidth comprises receiving the maximum supported radio frequency bandwidth for each supported band.

7. The method of claim 4 , wherein receiving a number of supported carriers comprises receiving a number of supported carriers for each supported band.

8. 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 perform at least the following:
report a maximum radio frequency bandwidth supported by the apparatus in a capability field of at least one uplink report message to a base station, via a wireless connection;
report, via a plurality of information elements in the capability field, a number of carriers within said maximum radio frequency bandwidth supported by the apparatus in said at least one uplink report message to the base station, each of said carriers being a portion of said maximum radio frequency bandwidth and having a corresponding one of an information element among the plurality of information elements, said carriers collectively not occupying all of said maximum radio frequency bandwidth, thereby creating at least one gap between carriers in said maximum radio frequency bandwidth, wherein each of the corresponding information elements has a corresponding carrier parameter and a collective quantity of the plurality of information elements indicates the number of carriers supported;
report, via a maximum gap size information element in the capability field separate from the plurality of information elements, a maximum gap size between non-adjacent carriers to the base station, said non-adjacent carriers being those separated from one another by said at least one gap, wherein said maximum gap size is equal to a difference between the maximum radio frequency bandwidth and a sum of the bandwidths of the portions of the maximum frequency bandwidth occupied by said carriers; and
receive data in downlink from the base station on said non-adjacent carriers at the apparatus in accordance with the maximum radio frequency bandwidth, the number of carriers, and the maximum gap size reported to the base station,
wherein the apparatus is a user equipment.

9. The apparatus of claim 8 , wherein reporting the maximum supported radio frequency bandwidth comprises reporting the maximum supported radio frequency bandwidth for each supported band.

10. The apparatus of claim 8 , wherein reporting a number of supported carriers comprises reporting a number of supported carriers for each supported band.

11. 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 perform at least the following:
receive at the apparatus in a capability field of at least one uplink report message a maximum radio frequency bandwidth supported by a user equipment, via a wireless connection;
receive, via a plurality of information elements in the capability field, at the appa
