    Abstract: Response frame modulation coding set (MCS) selection within single user, multiple user, multiple access, and/or MIMO wireless communications. With respect to any exchange between communication devices in which there is a response frame, a first frame (e.g., an eliciting frame) is a first transmitted from the eliciting communication device to the responding communication device, and a second frame (e.g., a response frame) is transmitted from the responding communication device to the eliciting communities device. Appropriate selection of MCS to be used within the response frame may be determined explicitly or implicitly. One or more parameters (e.g., a limit parameter, a reduction parameter, etc.) may be used to determine the MCS of the response frame. The MCS employed for a response frame may be selected from a basic MCS set that ensures all response frames from any responding communication device may be properly received by the eliciting communication device.

    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: Channel characterization and training within multiple user, multiple access, and/or MIMO wireless communications. Within such communication systems, there can be a number of devices (e.g., STAs) that communicate with a single device (e.g., AP). A multi-cast sounding frame may be transmitted from a transmitting device to a number of receiving devices. Appropriate scheduling or ordering of feedback signals from some or all of the receiving devices may be performed explicitly (e.g., sounding frame sent from the transmitting device to a receiving device) or implicitly (e.g., control information sent from the transmitting device to the receiving device, sounding frame sent to the transmitting device from the receiving device). Such characterization and training is with respect to a channel or path in which data will subsequently follow. Such characterization and training can be performed in accordance with group membership (e.g., with respect to only some of the receiving devices).

    Abstract: Transmission coordination within multiple user, multiple access, and/or MIMO wireless communications. Within wireless communication systems, there can be various wireless communication devices therein that are not all compliant with a common capability set, communication protocol, communication standard, recommended practice, etc. For example, some communication systems may have some wireless communication devices characterized as ‘legacy’ wireless communication devices, and other wireless communication devices therein may be newer and compliant with newer capability sets, communication protocols, communication standards, recommended practices, etc. In such instances, coordination of transmissions among the various wireless communication devices may be made, when performing simultaneous transmissions, by ensuring that transmissions of devices on different channels is made when aligned on a common boundary of an OFDM symbol. Alternatively, such simultaneous transmissions may be made when offset by some multiple of OFDM symbol duration. When performing non-simultaneous transmissions, transmissions may be made based on channel availability.
