Error correction for a persistent resource allocation
First Claim
1. A client station comprising:
- a receiver configured to receive persistent allocation information including a dedicated affirmative acknowledgment (ACK) channel and a shared a negative acknowledgment (NACK) channel;
a mapping module configured to decode the persistent allocation information;
a NACK module configured to selectively create a NACK message; and
a transmitter configured to transmit the NACK message over the shared NACK channel.

Abstract
Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station can allocate persistent resources to a client station, and can associate the client station or persistent resource allocation with a particular shared NACK channel. The base station can monitor the NACK channel for a NACK indicating a map error. The base station can also monitor the resource allocation to implicitly determine a map error. The base station can 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 can monitor persistent resource allocation information elements in map messages and can indicate failure to receive a persistent resource allocation information element in a NACK message on a preassigned share NACK channel.

a receiver configured to receive persistent allocation information including a dedicated affirmative acknowledgment (ACK) channel and a shared a negative acknowledgment (NACK) channel; a mapping module configured to decode the persistent allocation information; a NACK module configured to selectively create a NACK message; and a transmitter configured to transmit the NACK message over the shared NACK channel. - View Dependent Claims (3)

2. A client station comprising:
-
a receiver configured to receive a resource map; a mapping module configured to determine whether a persistent allocation information element is within the resource map and configured to attempt to decode the persistent allocation information element; and a NACK module configured to selectively create a map NACK message for transmission over a shared map NACK channel on a condition that the mapping module is unable to successfully decode the persistent allocation information element.

4. A client station comprising:
-
a receiver configured to receive a resource map; a mapping module configured to determine whether a persistent allocation information element is within the resource map and decode the persistent allocation information element; and a NACK module configured to selectively create a NACK message for transmission over a shared NACK channel on a condition that the mapping module is unable to successfully decode the persistent allocation information element.

5. 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; transmitting the persistent allocation information element; and receiving a NACK message over the shared NACK channel. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. A base station comprising:
-
a scheduler configured to schedule a candidate client station for persistent uplink resource allocation; an information element (IE) generator configured to associate the candidate client station with a dedicated affirmative acknowledgment (ACK) channel and a shared negative acknowledgment (NACK) channel and to configure a persistent allocation information element identifying a persistent uplink resource allocation; a transmitter configured to transmit the persistent allocation information element; and a receiver configured to receive a NACK message over the shared NACK channel. - View Dependent Claims (13, 14, 15, 16)
