Abstract

Disclosed is a method, apparatus and a computer readable memory medium that stores a program of computer instructions for enabling a resource allocation to be made for user equipment. The method includes forming a resource allocation for a particular system bandwidth, where the resource allocation has a larger number of resource blocks than a maximum number of resource blocks associated with the particular system bandwidth, while maintaining a same resource block group size as would be present with the maximum number of resource blocks for the particular system bandwidth. The step of forming includes the use of an extended parameter in a derivation of the resource allocation. The method further includes transmitting information descriptive of the resource allocation to user equipment. The resource allocation may be a downlink resource allocation or an uplink resource allocation.

Claims

1. A method, comprising:

forming a resource allocation for a first system bandwidth that is larger than a second system bandwidth, where the resource allocation comprises a larger number of resource blocks than a maximum number of resource blocks associated with the second system bandwidth while maintaining a same resource block group size as would be present with the maximum number of resource blocks for the second system bandwidth, where forming comprises use of an extended parameter in a derivation of the resource allocation; and

transmitting information descriptive of the resource allocation to a mobile device.

2. The method of claim 1, where the extended parameter is one that expresses a downlink bandwidth configuration in multiples of a resource block size in the frequency domain, expressed as a number of frequency subcarriers.

3. The method of claim 1, where the extended parameter is one that expresses an uplink bandwidth configuration in multiples of a resource block size in the frequency domain, expressed as a number of frequency subcarriers.

6. The method of claim 2, where the extended parameter effectively scales a resource allocation field to provide a larger downlink system bandwidth than that provided by a second downlink system bandwidth of the second system bandwidth.

7. The method of claim 3, where the extended parameter effectively scales a resource allocation field to provide a larger uplink system bandwidth than that provided by a second uplink system bandwidth of the second system bandwidth.

8. The method of claim 2, where the particular downlink system bandwidth is about 1.4 MHz, and where the larger downlink system bandwidth that is provided is in a range of about 1.4 MHz to about 2.8 MHz, or where the particular downlink system bandwidth is about 3 MHz, and where the larger downlink system bandwidth that is provided is in a range of about 3 MHz to about 4.8 MHz, or where the particular downlink system bandwidth is about 5 MHz, and where the larger downlink system bandwidth that is provided is in a range of about 5 MHz to about 9.8 MHz, or where the particular downlink system bandwidth is about 10 MHz, and where the larger downlink system bandwidth that is provided is in a range of about 10 MHz to about 14.8 MHz, or where the particular downlink system bandwidth is about 15 MHz, and where the larger downlink system bandwidth that is provided is in a range of about 15 MHz to about 19.8 MHz, or where the particular downlink system bandwidth is about 20 MHz, and where the larger downlink system bandwidth is greater than 20 MHz.

14. The method of claim 3, where the particular uplink system bandwidth is about 1.4 MHz, and where the larger uplink system bandwidth that is provided is in a range of about 1.4 MHz to about 2.8 MHz, or where the particular downlink system bandwidth is about 3 MHz, and where the larger downlink system bandwidth that is provided is in a range of about 3 MHz to about 4.8 MHz, or where the particular downlink system bandwidth is about 5 MHz, and where the larger downlink system bandwidth that is provided is in a range of about 5 MHz to about 9.8 MHz, or where the particular downlink system bandwidth is about 10 MHz, and where the larger downlink system bandwidth that is provided is in a range of about 10 MHz to about 14.8 MHz, or where the particular downlink system bandwidth is about 15 MHz, and where the larger downlink system bandwidth that is provided is in a range of about 15 MHz to about 19.8 MHz, or where the particular downlink system bandwidth is about 20 MHz, and where the lamer downlink system bandwidth is greater than 20 MHz.

20. The method of claim 1, where the extended parameter is signaled to the mobile device using a master information block.

21. The method of claim 1, where the extended parameter is signaled to the mobile device using a system information block.

22. The method of claim 1, where the extended parameter is signaled to the mobile device using radio resource control signaling.

23. The method of claim 1, further comprising:

receiving a channel quality indicator that comprises measurement information obtained from the first system bandwidth.

24. The method of claim 1, where the larger number of resource blocks are disposed symmetrically about the maximum number of resource blocks associated with the second system bandwidth.

25. The method of claim 1, where the larger number of resource blocks are disposed asymmetrically about the maximum number of resource blocks associated with the second system bandwidth.
