Abstract

Claims (42)

1. A method of wireless communication between a base station and at least one mobile station, the method comprising:

receiving a request for a data rate from said at least one mobile station on a reverse link channel to said base station; and

in response to said request, skipping a first slot after a delay for a portion of a slot on a forward link transmission before transmitting a data packet in a second slot, wherein skipping the first slot comprises:

determining if a current value of said data rate request differs from a previous value of a previously received data rate request;

marking the current value as a new value for the first slot of the forward link transmission; and

delaying scheduling said request until after the first slot.

2. A method, as set forth in claim 1 , wherein said skipping a first slot further comprises:

skipping a slot immediately after a half slot delay.

3. A method, as set forth in claim 2 , wherein said skipping said first slot further comprises:

receiving the current value associated with said request in at least one slot of a data rate channel;

comparing the current value to the previous value received for said first slot on a reverse link transmission; and

determining whether the current value is different than the previous value.

4. A method, as set forth in claim 3 , further comprising:

if the current value is different than the previous value, causing a decoder of a modem for a reverse link to indicate a new value associated with said first slot.

5. A method, as set forth in claim 3 , further comprising:

if the current value is determined not to be the same as the previous value, replacing the previous value with the current value; and

marking the current value as a new value for said first slot.

6. A method, as set forth in claim 3 , further comprising:

if said value is determined to be the same as said another value that is received previously, making said another value as an old value associated with said first slot; and

scheduling said request.

7. A method, as set forth in claim 3 , further comprising:

adding a delay of said first slot to increase a range of a cell; and

using said delay to support a cell configuration different than one based on said half slot delay.

8. A method, as set forth in claim 1 , further comprising:

using said first slot for preparing to decode a reverse link transmission during said second slot.

9. A method, as set forth in claim 1 , further comprising:

using said first slot for preparing to start said forward link transmission at the beginning of said second slot.

10. A method, as set forth in claim 1 , further comprising:

receiving said request on a data request channel from said at least one mobile station in at least two slots; and

scheduling a user in said second slot based on said request.

11. A method, as set forth in claim 10 , further comprising:

determining whether said request on the data request channel is a new data request; and

if said request is a new data request, scheduling said forward link transmission to start at the beginning of said second slot to transmit said data packet to said at least one mobile station.

12. A method, as set forth in claim 11 , further comprising:

decoding said new data request in said first slot.

13. A method, as set forth in claim 1 , further comprising:

receiving said request of a length on a data request channel at said base station; and

determining the length of said request on said data request channel that said at least one mobile station is using.

14. A method, as set forth in claim 13 , wherein determining the length of said request, further comprises:

if the length of said request is a single slot, delaying scheduling of a user in said second slot.

15. A method, as set forth in claim 14 , further comprising:

in response to detecting a consecutive second request same as said request, scheduling said user.
