Client station configured for operation based on persistent resource allocation information
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.
1. A method of performed by a client station, the method comprising:
receiving, by the client station, persistent resource allocation information, the persistent resource allocation information including an indication of downlink (DL) persistent resources, a first identifier associated with the client station, an indication of a DL allocation period, an indication of uplink (UL) persistent resources, and an indication of an UL allocation period;
periodically receiving, by the client station, DL user data associated with the first identifier, the DL user data being received via the DL persistent resources and based on the DL allocation period, and the DL persistent resources repeating at an interval defined by the DL allocation period; and
persistently transmitting, by the client station, UL user data via the UL persistent resources and based on the UL allocation period, the UL persistent resources repeating at an interval defined by the UL allocation period.
2. The method of claim 1 , further comprising:
receiving non-persistent resource allocation information including an indication of non-persistent resources and a second identifier associated with the client station; and
receiving second DL user data associated with the second identifier using the non-persistent resources.
3. The method of claim 1 , further comprising:
subsequent to receiving the persistent resource allocation information, receiving an indication of a release of the persistent resources; and
transmitting an indication of a positive acknowledgement (ACK) of the release.
4. The method of claim 1 , wherein the DL allocation period is different than the UL allocation period.
5. The method of claim 1 , further comprising:
receiving an offset indication, wherein the offset indication indicates an offset in a region of the UL persistent resources, wherein the UL persistent resources are based; and
the persistently transmitting further including transmitting the UL user data via resources based on the offset.
6. The method of claim 1 , wherein the persistent resource allocation information is received via a control channel, and wherein the DL user data is received via a shared channel.
7. The method of claim 1 , wherein at least one of the UL persistent resources and the DL persistent resources are used in voice over Internet protocol (VoIP) communication.
8. The method of claim 1 , wherein the persistent resource allocation information further includes an indication of UL resources for hybrid automatic repeat request (HARQ) information.
9. The method of claim 1 , wherein the receiving the persistent resource allocation information includes receiving a plurality of persistent resource allocation messages.
10. The method of claim 1 , wherein the first identifier is selected from a predetermined range of values.
11. A client station comprising:
a receiver operable to:
receive persistent resource allocation information, the persistent resource allocation information including an indication of downlink (DL) persistent resources, a first identifier associated with the client station, an indication of DL allocation period, an indication of uplink (UL) persistent resources, and an indication of an UL allocation period; and
periodically receive DL user data associated with the first identifier, the DL user data being received via the DL persistent resources and based on the DL allocation period, and the DL persistent resources repeating at an interval defined by the DL allocation period; and
a transmitter operable to persistently transmit UL user data via the UL persistent resources and based on the UL allocation period, the UL persistent resources repeating at an interval defined by the UL allocation period.
12. The client station of claim 11 , wherein the receiver is further operable to:
receive non-persistent resource allocation information including an indication of non-persistent resources and a second identifier associated with the client station; and
receive second DL user data associated with the second identifier using the non-persistent resources.
13. The client station of claim 11 , wherein:
the receiver is further operable to, subsequent to receiving the persistent resource allocation information, receive an indication of a release of the persistent resources; and
the transmitter is further operable to transmit an indication of a positive acknowledgement (ACK) of the release.
14. The client station of claim 11 , wherein the DL allocation period is different than the UL allocation period.
15. The client station of claim 11 , wherein:
the receiver is further operable to receive an offset indication, wherein the offset indication indicates an offset in a region of the UL persistent resources; and
the transmitter is further operable to transmit the UL user data via resources that are based on the offset.
16. The client station of claim 11 , wherein the persistent resource allocation information is received via a control channel, and wherein the DL user data is received via a shared channel.
17. The client station of claim 11 , wherein at least one of the UL persistent resources and the DL persistent resources are used in voice over Internet protocol (VoIP) communication.
18. The client station of claim 11 , wherein the persistent resource allocation information further includes an indication of UL resources for hybrid automatic repeat request (HARQ) information.
19. The client station of claim 11 , wherein the persistent resource allocation information includes a plurality of persistent resource allocation messages.
20. The client station of claim 11 , wherein the first identifier is selected from a predetermined range of values.
