Abstract: Aspects of a method and system for mitigating interference among femtocells via intelligent channel selection are provided. In this regard, signals which may interfere with cellular communications between a femtocell and a cellular communication device may be detected via the femtocell. Based on the detection, the femtocell may be configured to transmit and/or receive signals on one or more frequencies and/or channels. The one or more frequencies and/or channels may be determined in the femtocell and/or in a network management entity. Detecting interfering signals and configuring the one or more femtocells may occur periodically, upon installation of a femtocell, upon power-up of a femtocell, and/or upon command from a network administrator. The results of the detection may be communicated to one or more other femtocells and/or to a network management entity.

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).

Abstract: A communication device includes a processor configured to generate OFDMA packets using various OFDMA packet structures and to transmit such OFDMA packets, via a communication interface, to at least one other communication device. The processor is also configured to receive, interpret, and process such OFDMA packets. One example of an OFDMA packet includes common SIG for two or more other wireless communication devices modulated across all sub-carriers of the OFDMA packet. The common SIG is followed by first SIG and first data for a first other wireless communication device modulated across first subset of the sub-carriers of the OFDMA packet and is also followed by second SIG and second data for a second other wireless communication device modulated across second subset of the sub-carriers of the OFDMA packet. Another example of an OFDMA packet includes the common SIG followed directly by first data and second data modulated as described above.

Abstract: A multi-user super-frame (MU-SF), as controlled by a MU-SF owner, is used to govern the manner by which various wireless communication devices have access to the communication medium. When various wireless communication devices operate within a wireless communication system, communication medium access can be handled differently for wireless communication devices having different capabilities. Per the MU-SF, those having a first capability may get medium access in accordance with a first operational mode (e.g., carrier sense multiple access/collision avoidance (CSMA/CA)), while those having a second capability may get medium access in accordance with a second operational mode (e.g., scheduled access). The respective durations for each of the first operational mode and the second operational mode within various MU-SFs need not be the same; the respective durations thereof may be adaptively modified based on any number considerations.

Abstract: Multi-user null data packet (MU-NDP) sounding within multiple user, multiple access, and/or MIMO wireless communications. Within communication systems including multiple wireless communication devices (e.g., one or more APs, STAs, etc.), channel sounding of the selected communication links between the various wireless communication devices is performed. A MU-NDP announcement frame is transmitted to and received by various wireless communication devices indicating which of those wireless communication devices (e.g., one, some, or all) are being sounded. Then, respective NDP sounding frames are transmitted via the communication links corresponding to those wireless communication devices (e.g., one, some, or all) are being sounded, and sounding feedback signals are subsequently sent back to the original transmitting wireless communication device. In some instances, after transmission of the MU-NDP announcement frame, a clear to send (CTS) is sent from at least one of the wireless communication devices thereby precipitating the transmission of the NDP sounding frames.
