PERSISTENT RESOURCE ALLOCATION
First Claim
1. A method of receiving a persistent allocation, comprising:
- receiving a first information element specifying a first persistent allocation occurring at a fixed point with an a logical mapping;
receiving a second information element including a mask; and
continuing to operate according to the first persistent allocation if the mask indicates that the first persistent allocation has not been deallocated and that no persistent allocation occurring logically earlier than the first persistent allocation has been deallocated.

Abstract
Methods and apparatus for communicating and utilizing persistent allocation of uplink resources are described herein. A base station can allocate persistent uplink resources to a client station, such that the resource allocation remains active for future uplink frames without the client station repeating a request for uplink resources or the base station expressly communicating the uplink resource allocation. A client station can request a persistent uplink resource allocation when wireless channel conditions are fairly consistent and not varying and the required uplink resources are predictably periodic and fixed in size. The base station can verify that the uplink resource request meets the criteria for persistent allocation and can allocate persistent uplink resources in a dedicated information element of an uplink resource map that is transmitted to the user. The resources allocated remain allocated to the client station in each frame satisfying a predetermined periodicity until deallocated.

5. A method of efficiently assigning persistent resources, comprising:
-
sending one or more information elements specifying a first, second and third persistent allocation for a first, second and third client station respectively, wherein the first, second and third persistent allocations occur in numerical order in a logical mapping; and sending a subsequent information element including a mask to commanding the second client station cease operation on the second persistent allocation. - View Dependent Claims (6)

15. A method of efficiently assigning persistent resources, the method comprising:
-
sending one or more information elements specifying a first, second and third persistent allocation for a first, second and third client station respectively, wherein the first, second and third persistent allocations occur in numerical order in a logical mapping; determining a need for an update to the second persistent allocation; and sending a subsequent information element specifying a start location and a revised second and third allocation, wherein the start allocation indicates a delineation with the logical mapping between a set of previously assigned allocations and a set of allocations defined by the subsequent information element.

16. A method of receiving a persistent allocation, the method comprising:
-
receiving a first information element specifying a first persistent allocation occurring at a fixed point with an a logical mapping; receiving a second information element specifying a start allocation indicating a change point within the logical mapping; and continuing to operate according to the first persistent allocation if the fixed point occurs logically before the change point. - View Dependent Claims (17, 18)
