Mixed mode operations within multiple user, multiple access, and/or MIMO wireless communications

摘要

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).

1. A wireless communication device comprising:
a processing circuitry configured to:
generate an orthogonal frequency division multiple access (OFDMA) frame that includes information that specifies:
a first time period for simultaneous communication medium access by a first other wireless communication device and a second other wireless communication device that both have a first capability based on a first communication protocol, a first cluster that includes a first set of OFDMA tones for use by a first other wireless communication within the first time period, and a second cluster that includes a second set of OFDMA tones for use by a second other wireless communication within the first time period;a second time period for communication access based on carrier sense multiple access/collision avoidance (CSMA/CA) by a third other wireless communication device that has a second capability based on a second communication protocol;transmit the OFDMA frame to the first other wireless communication device, the second other wireless communication device, and the third other wireless communication device;receive, during the first time period, first data from the first other wireless communication device that is transmitted via the first cluster that includes the first set of OFDMA tones and second data from the second other wireless communication device that is transmitted via the second cluster that includes the second set of OFDMA tones; andreceive, during the second time period, third data from the third other wireless communication device.
