Abstract

Embodiments include systems and methods for frame tunneling in a wireless communications system comprising digital beam forming. Embodiments comprise a first and second frame control field with the second frame control field comprising a High Throughput Control (HTC) enabling field. If the HTC enabling field is enabled, then an HTC field is sent.

Claims

1. An apparatus, comprising:

a wireless station adapted for communications in a wireless network;

wherein the wireless network uses a High Throughput Control (HTC) field for signaling such that the HTC field can be concatenated with control frames and requires that any station shall assert a network allocation vector (NAV) when any frame of a first type and a first subtype has been received, the first type and the first subtype indicative of a frame with the HTC field; and

wherein the wireless station is configured to encode the frame with the first subtype and is constructed to deliver the frame as a Control Frame +HTC to wireless stations operable in the wireless network, thereby enabling other stations operating in the wireless network to be able to assert the NAV from a duration field of the frame, wherein the Control Frame +HTC is a control frame that comprises an HTC field.

2. The apparatus of claim 1, wherein the frame further comprises:

a first control field prior to the duration field defining the first subtype;

an address 1 field following the duration field;

second control field following the address 1 field comprising a byte count field, a subtype field indicating a control subtype concatenated with the HTC field and an HTC enabling field that if set to one will indicate that the HTC field is included with the second control field.

3. The apparatus of claim 2, wherein the wireless station uses one subtype in the first control field to deliver different control frames to preserve a limited range of applicable subtypes.

4. The apparatus of claim 1, wherein the frame further comprises the duration field to specify a duration of transmission of the frame.

5. The apparatus of claim 1, wherein the frame further comprises a Frame Check Sequence (FCS).

6. The apparatus of claim 1, further comprising a transceiver with a digital beam former and an array of antennas to transmit the frame through a spatial channel to a receiving communication device.

7. The apparatus of claim 1, wherein different control frames that can be submitted include modified control frames defined in an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.

8. The apparatus of claim 1, wherein different control frames that can be submitted include new frames defined in an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.

9. An apparatus, comprising:

a wireless station adapted for communications in a wireless network, the wireless station to use a frame format that includes;

a first control field of the frame, prior to a duration field, defining a subtype using a type field and a subtype field;

an address 1 field following the duration field;

a second control field following the address 1 field comprising a byte count field, a subtype field indicating a control subtype concatenated with the HTC field, and a high throughput control (HTC) enabling field that if set to one will indicate that the HTC field is included with the second control field.

10. The apparatus of claim 9, wherein the frame further comprises the duration field to specify a duration of transmission of the frame.

11. The apparatus of claim 9, wherein the frame further comprises a Frame Check Sequence (FCS).

12. The apparatus of claim 9, further comprising a transceiver with a digital beam former and an array of antennas to transmit the frame through a spatial channel to a receiving communication device.

13. The apparatus of claim 9, wherein the wireless station uses one subtype in the first control field to deliver different control frames to preserve a limited range of applicable subtypes.

14. The apparatus of claim 13, wherein different control frames that can be submitted include modified control frames defined in an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.

18. The method of claim 11, wherein generating the frame comprises generating the frame comprising the HTC enabling field set to disable.

19. The method of claim 11, wherein the first station uses one subtype in the first control field to deliver different control frames to preserve a limited range of applicable subtypes.

15. A method, comprising:

operating, by a wireless station adapted for communications in a wireless network, wherein the wireless network uses a High Throughput Control (HTC) field for signaling such that the HTC field can be concatenated with control frames and requires that any station shall assert a network allocation vector (NAV) when any frame of a first type and a first subtype has been received, the first type and the first subtype indicative of a frame with the HTC field; and

generating, by the first station, the frame with a first subtype, the frame being constructed to deliver a Control Frame +HTC to wireless stations operable in the wireless network, thereby enabling other stations operating in the wireless network to be able to assert the NAV from a duration field of the frame, wherein the Control Frame +HTC is a control frame that comprises an HTC field.

16. The method of claim 15, further comprising transmitting the frame through a spatial channel to a receiving communication device via a transceiver with a digital beam former and an array of antennas.

17. The method of claim 15, wherein generating the frame comprises generating the frame comprising:

a first control field prior to the duration field defining the first subtype;

an address 1 field following the duration field;

a second control field following the address 1 field comprising a byte count field, a subtype field indicating a control subtype concatenated with the HTC field and an HTC enabling field that if set to one will indicate that the HTC field is included with the second control field.

20. The method of claim 15, wherein different control frames that can be submitted include modified control frames defined in an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.
