Abstract

A time domain multiple access/time division duplex (TDMA/TDD) media access control (MAC) transmission frame includes: one or more dynamically allocatable control packets for providing control information over a wireless medium between a wireless base station and one or more subscriber customer premises equipment (CPE) stations; and one or more dynamically allocatable data packets for providing data information over a wireless medium between a wireless base station and one or more subscriber customer premises equipment (CPE) stations. The control packets can include at least one of: a downstream acknowledgment slot; a reservation request slot; an operations data slot; an upstream acknowledgment slot; an acknowledgment request slot; a frame descriptor slot; a command and control slot.

Claims (48)

1. A method of communicating control information and data information in a transmission frame comprising:

dividing a transmission frame into a plurality of slots;

designating at least one of said plurality of slots as at least one dynamically allocatable control slot; and

designating at least one of said plurality of slots as at least one dynamically allocatable data slot for communicating an IP flow comprising one or more packets over a shared wireless communication medium;

wherein said at least one dynamically allocatable control slot includes information about a number of one or more packets in a second IP flow and at least one end user quality of service (QoS) requirement of said second IP flow;

wherein said at least one dynamically allocatable control slot comprises a dynamically allocatable number of reservation request contention slots for receiving reservation requests for available dynamically allocatable data slots of said shared wireless communication medium; and

wherein said dynamically allocatable number of reservation request contention slots is increased or decreased dynamically according to a frequency of detected collisions between said reservation requests.

2. The method of claim 1 , wherein said at least one dynamically allocatable control slot comprises at least one of:

a downstream acknowledgment slot;

a reservation request slot;

an operations data slot;

an upstream acknowledgment slot;

an acknowledgment request slot;

a frame descriptor slot; and

a command and control slot.

3. The method of claim 1 , wherein said at least one dynamically allocatable control slot comprises a reservation request slot including information about data payload contents.

4. The method of claim 1 , wherein said transmission frame comprises:

at least one downlink subframe for communication from a wireless base station to at least one subscriber customer premises equipment (CPE) station over said shared wireless communication medium; and

an uplink subframe for communication from said at least one subscriber CPE station to said wireless base station over said shared wireless communication medium.

5. The method of claim 1 , wherein said transmission frame comprises:

at least one downlink subframe for communication from a wireless access point to at least one station over said shared wireless communication medium; and

at least one uplink subframe for communication from said station to said wireless access point over said shared wireless communication medium.

6. The method of claim 1 , wherein said information about said at least one end user quality of service (QoS) requirement of said second IP flow comprises a class of said second IP flow.

7. The method of claim 6 , further comprising a step of classifying said IP flow into one of a plurality of classes according to said class of said second IP flow.

8. The method of claim 1 , wherein said dynamically allocatable number of reservation request contention slots is increased in response to an increase in said detected collisions, and is decreased in response to an decrease in said detected collisions.

9. A method of transmitting in a transmission frame information about an IP flow, comprising:

communicating over a shared wireless communication medium in at least one control slot of a first transmission frame a number of packets in an IP flow to be communicated in at least one data slot of a later transmission frame;

communicating in said at least one control slot of said first transmission frame at least one quality of service (QoS) requirement of said IP flow;

wherein said transmission frame comprises a dynamically allocatable number of reservation request contention slots for communicating reservation requests for available slots of said at least one data slot of said later transmission frame; and

wherein said dynamically allocatable number of reservation request contention slots is dynamically allocated according to a frequency of detected collisions between said reservation requests.

10. The method of claim 9 , further comprising communicating data from another IP flow in at least one data slot of said first transmission frame.

11. The method of claim 9 , wherein said at least one control slot comprises a reservation request slot including information about data payload contents.

12. The method of claim 9 , wherein said first transmission frame comprises:

at least one downlink subframe for communication from a wireless base station to at least one subscriber customer premises equipment (CPE) station over said shared wireless communication medium; and

at least one uplink subframe for communication from said at least one subscriber CPE station to said wireless base station over said shared wireless communication medium.

13. The method of claim 9 , wherein said first transmission frame comprises:

at least one downlink subframe for communication from a wireless access point to at least one station over said shared wireless communication medium; and

at least one uplink subframe for communication from said station to said wireless access point over said shared wireless communication medium.

14. The method of claim 9 , wherein said at least one quality of service (QoS) requirement of said IP flow corresponds to a class of said IP flow.

15. The method of claim 14 , further comprising a step of classifying said IP flow into one of a plurality of classes according to said class of said IP flow.

16. The method of claim 9 , wherein said communicating step includes at least one of:

communicating over a radio frequency local area network;

communicating over a radio frequency wide area network;

communicating over a line-of-sight wireless communications network;

communicating over an infrared wireless communications network;

communicating over a communications network including a laser; and

communicating over a point-to-point wireless communications network.

17. The method of claim 9 , wherein said communicating comprises communicating over a coaxial cable wireless communication medium.
