Error correction for a persistent resource allocation
First Claim
1. A method of persistent resource allocation, the method comprising:
- scheduling a candidate client station for a persistent resource allocation;
associating the candidate client station with a dedicated affirmative acknowledgment (ACK) channel and a shared negative acknowledgment (NACK) channel;
configuring a persistent allocation information element indicating the persistent resource allocation, the dedicated ACK channel, and the shared NACK channel; and
transmitting the persistent allocation information element.

Abstract
Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station may allocate persistent resources to a client station, and may associate the client station or persistent resource allocation with a particular shared NACK channel. The base station may monitor the NACK channel for a NACK indicating a map error. The base station may monitor the resource allocation to implicitly determine a map error. The base station may resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation may monitor persistent resource allocation information elements in map messages and/or may indicate failure to receive a persistent resource allocation information element in a NACK message on a shared NACK channel.

7. A method of persistent resource allocation, the method comprising:
-
communicating a persistent resource allocation information element; receiving a negative acknowledgment (NACK) indication on a shared NACK channel; and retransmitting at least a portion of the persistent resource allocation information element to at least one of a group of client stations associated with the shared NACK channel.

8. A method of persistent uplink resource allocation, the method comprising:
-
receiving a resource map; attempting to decode a persistent allocation information element within the resource map; and selectively transmitting a negative acknowledgment (NACK) over a shared NACK channel if unable to successfully decode the persistent allocation information element. - View Dependent Claims (9, 10, 11)

17. A base station comprising:
-
a transmitter configured to communicate a persistent resource allocation information element; and a receiver configured to receive a negative acknowledgment (NACK) indication on a shared NACK channel; wherein the transmitter is configured, on a condition that the NACK indication is received, to retransmit at least a portion of the persistent resource allocation information element to at least one of a group of client stations associated with the shared NACK channel.
