Abstract

Multiple channel transmission in mmW Wireless Local Area Network (WLAN) systems may be provided. Multi-channel aggregation and channel bonding may include, for example, multi-channel aggregation for a single transmitter/receiver pair or multi-channel aggregation and bonding for multiple transmitter/receiver pairs with frequency and space based multiple access. Multi-channel beamforming may include, for example, one analog beam across two channels and analog circuits on each channel or a single analog circuit on both channels, one analog beam across two channels and separate digital precoding schemes on each channel, one analog beam across a primary channel and separate digital precoding schemes on each channel or two analog beams on two channels and separate digital precoding on each channel. Preamble signaling may be provided.

First claim

What is claimed is:

1. A device comprising:
a processor configured to:
determine to transmit an enhanced directional multi-gigabit (EDMG) packet frame, wherein the EDMG packet frame comprises a legacy-header (L-header), and wherein the L-header comprises a length field, a training length field, and a modulation and coding set (MCS); and
determine values of the length field, the training length field, and the MCS, wherein when the values of the length field, the training length field, and the MCS are used to calculate a transmitter time (TXTIME), the TXTIME is approximately a same duration as an EDMG packet frame duration; and

a transmitter configured to:
send the EDMG packet frame with the length field of the L-header set to the determined value, and wherein reserved bit 46 in the L-header is set to a value of 1.

2. The device of claim 1 , wherein the device comprises a station or an access point (AP).

3. The device of claim 1 , wherein the processor is further configured to determine a duration associated with the EDMG packet frame.

4. The device of claim 1 , wherein the EDMG packet frame comprises at least one of an L-header packet type field, an L-header beam tracking requested field, or a packet type field.

5. The device of claim 1 , wherein the EDMG packet frame is a DMG single carrier (SC) physical (PHY) frame.

6. The device of claim 1 , wherein the length field of the L-header set is less than a predetermined value.

7. A method comprising:
determining to transmit, by a device, an enhanced directional multi-gigabit (EDMG) packet frame, wherein the EDMG packet frame comprises a legacy-header (L-header), and wherein the L-header comprises a length field, a training length field, and a modulation and coding set (MCS);
determining values of the length field, the training length field, and the MCS, wherein when the values of the length field, the training length field, and the MCS are used to calculate a transmitter time (TXTIME), the TXTIME is approximately a same duration as an EDMG packet frame duration; and
sending the EDMG packet frame with the length field of the L-header set to the determined value, and wherein reserved bit 46 in the L-header is set to a value of 1.

8. The method of claim 7 , wherein the device comprises a station or an access point (AP).

9. The method of claim 7 further comprising: determining a duration associated the EDMG packet frame.

10. The method of claim 7 , wherein the EDMG packet frame comprises at least one of an L-header packet type field, an L-header beam tracking requested field, or a packet type field.

11. The method of claim 7 , wherein the EDMG packet frame is a DMG single carrier (SC) physical (PHY) frame.

12. The method of claim 7 , wherein the length field of the L-header set is less than a predetermined value.
