Abstract

Mixed mode operations within multiple user, multiple access, and/or MIMO wireless communications. Certain communication systems can include wireless communication devices of various capabilities therein (e.g., IEEE Task Group ac (TGac VHT), IEEE 802.11 amendment TGn, IEEE 802.11 amendment TGa, and/or other capabilities, etc.). In one manner of classification, wireless communication devices having legacy and newer/updated capabilities may inter-operate with one another, operate within a common region, and/or communicate via a common access point (AP). Coordination of such wireless communication devices (e.g., legacy and newer/updated) provides for their respective operation on a same set of clusters in accordance with various operational modes including: (1) time dividing medium access between the wireless communication devices of various capabilities, (2) assigning primary cluster(s) for a first capability set and assigning non-primary cluster(s) for a second capability set, etc., and/or (3) any combination of operational modes (1) and (2).

First claim

What is claimed is:

1. A wireless communication device comprising:
a communication interface; and
processing circuitry that is coupled to the communication interface, wherein at least one of the communication interface or the processing circuitry configured to:
generate a first orthogonal frequency division multiple access (OFDMA) frame that includes information that specifies a first time period during which a first other wireless communication device is to transmit first information via a first subset of OFDMA sub-carriers of a communication channel to the wireless communication device, wherein the first other wireless communication device has a first capability based on a first communication protocol;
transmit the first OFDMA frame to the first other wireless communication device;
receive the first information from the first other wireless communication device via the first subset of OFDMA sub-carriers of the communication channel during the first time period specified within the first OFDMA frame;
generate a second OFDMA frame that includes information that specifies a second time period during which a second other wireless communication device is to transmit second information via a second subset of OFDMA sub-carriers of the communication channel to the wireless communication device and also during which a third other wireless communication device is to transmit third information via a third subset of OFDMA sub-carriers of the communication channel to the wireless communication device, wherein both the second other wireless communication device and the third other wireless communication device have a second capability based on a second communication protocol that is different than the first capability based on the first communication protocol;
transmit the second OFDMA frame to the second other wireless communication device and the third other wireless communication device; and
receive the second information from the second other wireless communication device via the second subset of OFDMA sub-carriers of the communication channel and the third information from the third other wireless communication device via the third subset of OFDMA sub-carriers of the communication channel via another OFDMA frame during the second time period specified within the second OFDMA frame.

2. The wireless communication device of claim 1 , wherein the at least one of the communication interface or the processing circuitry is further configured to:
transmit the first OFDMA frame to the first other wireless communication device and also transmit the second OFDMA frame to the second other wireless communication device and the third other wireless communication device via the first subset of OFDMA sub-carriers of the communication channel that includes a primary cluster composed of one or more channels among one or more bands of the communication channel or via all of the OFDMA sub-carriers of the communication channel.

3. The wireless communication device of claim 1 , wherein the at least one of the communication interface or the processing circuitry is further configured to:
generate a third OFDMA frame that includes information that specifies a third time period during which the first other wireless communication device is to transmit fourth information via the first subset of OFDMA sub-carriers of the communication channel to the wireless communication device and also specifies a fourth time period during which a fourth other wireless communication device is to transmit fifth information via the first subset of OFDMA sub-carriers of the communication channel to the wireless communication device, wherein the fourth other wireless communication device also has the first capability based on the first communication protocol;

6. The wireless communication device of claim 1 further comprising:
a cellular telephone, two-way radio, personal digital assistant (PDA), personal computer (PC), laptop computer, or home entertainment equipment.

7. The wireless communication device of claim 1 further comprising:
