Abstract

Signaling resource partition of a component carrier in a wireless communication system is disclosed. The number of primary resource blocks and the number of extension resource blocks of the component carrier is encoded and signaled to a UE, so the UE can obtain the resource partition of the component carrier.

Claims

1. A method of signaling one or more resource partitions of at least one component carrier in a wireless communication system, the method comprising:

encoding, by a transmitter in the wireless communication system, a number of primary resource blocks of a first component carrier;

encoding, by the transmitter, a number of extension resource blocks of said first component carrier according to a representation comprising the number of extension resource blocks for any supported number of primary resource blocks, wherein said encoded number of extension resource blocks determines, for the encoded number of primary resource blocks, the available number of extension resource blocks; and

signaling, by the transmitter, said encoded numbers of primary and extension resource blocks of said first component carrier to a receiver in the wireless communication system;

wherein said component carrier comprises at least one of a primary resource block and an extension resource block.

2. The method according to claim 1 wherein said signaling said encoded numbers of primary and extension resource blocks is signaling through at least one resource block of a component carrier.

3. The method according to claim 1 wherein said signaling said encoded numbers of primary and extension resource blocks is signaling through at least one resource block of said first component carrier.

4. A method of signaling one or more resource partitions of at least one component carrier in a wireless communication system, the method comprising:

encoding, by a transmitter in the wireless communication system, a number of primary resource blocks of a first component carrier;

encoding, by the transmitter, a number of extension resource blocks of said first component carrier according to a representation comprising the number of extension resource blocks for any supported number of primary resource blocks, wherein said encoded number of extension resource blocks determines, for the encoded number of primary resource blocks, the available number of extension resource blocks;

signaling, by the transmitter, said encoded number of primary resource blocks through at least one primary resource block of said first component carrier to a receiver in the wireless communication system; and

signaling, by the transmitter, said encoded number of extension resource blocks,

wherein said component carrier comprises at least one of a primary resource block and an extension resource block.

5. The method according to claim 4, wherein encoding the number of extension resource blocks of said first component carrier comprises:

encoding the number of extension resource blocks with an encoding method being independent of the number of primary resource blocks of said first component carrier.

6. The method according to claim 4, wherein encoding the number of extension resource blocks of said first component carrier comprises:

encoding the number of extension resource blocks and the number of primary resource blocks of said first component carrier with a joint encoding method.

7. The method according to claim 4, wherein encoding the number of extension resource blocks of said first component carrier comprises:

encoding the number of extension resource blocks with an encoding method being dependent on the number of primary resource blocks of said first component carrier.

8. The method according to claim 4, wherein signaling said encoded number of extension resource blocks comprises:

signaling said encoded number of extension resource blocks through at least one primary resource block of a component carrier.

9. The method according to claim 4, wherein signaling said encoded number of extension resource blocks comprises:

signaling said encoded number of extension resource blocks through at least one extension resource block of a component carrier.

10. The method according to claim 4, wherein signaling said encoded number of extension resource blocks comprises:

signaling said encoded number of extension resource blocks through at least one subcarrier located between two component carriers.

11. The method according to claim 4, wherein said first component carrier only comprises extension resource blocks, and wherein the number of primary resource blocks of the component carrier is 0.

12. The method according to claim 4, wherein if said extension resource blocks of said first component carrier are located asymmetrically around said primary resource blocks of said first component carrier, the method further comprises:

encoding additional information on the location of said extension resource blocks of said first component carrier; and

signaling said encoded additional information on the location of said extension resource blocks.

13. A method for receiving signaling of one or more resource partitions of at least one component carrier in a wireless communication system, comprising:

receiving, by a receiver in the wireless communication system, an encoded number of primary resource blocks of a component carrier;

receiving, by the receiver, an encoded number of extension resource blocks of said component carrier;

decoding, by the receiver, said encoded number of primary resource blocks to obtain the number of primary resource blocks of said component carrier; and

decoding, by the receiver, said encoded number of extension resource blocks according to a representation comprising the number of extension resource blocks for any supported number of primary resource blocks to obtain the number of extension resource blocks of said component carrier,

wherein said component carrier comprises at least one of a primary resource block and an extension resource block.

14. The method according to claim 13, wherein decoding said encoded number of extension resource blocks comprises:

decoding said encoded number of extension resource blocks dependently on the number of primary resource blocks of said component carrier to obtain the number of extension resource blocks of said component carrier.

15. The method according to claim 13 wherein the number of extension resource blocks is indirectly represented by the total number of resource blocks of said component carrier or directly represented by the actual number of extension resource blocks of said component carrier.

16. An transmitter for signaling of one or more resource partitions of at least one component carrier in a wireless communication system, the transimitter comprising a processor configured to:

encode the number of primary resource blocks of a component carrier and the number of extension resource blocks of said component carrier according to a representation comprising the number of extension resource blocks, for any supported number of primary resource blocks, wherein said encoded number of extension resource blocks determines, for the encoded number of primary resource blocks, the available number of extension resource blocks;

signal said encoded number of primary and extension resource blocks of said component carrier,

wherein said component carrier comprises at least one of a primary resource block and an extension resource block.
