摘要： 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).

摘要： Medium accessing mechanisms within multiple user, multiple access, and/or MIMO wireless communications. 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.

摘要： Carrier sense multiple access (CSMA) for multiple user, multiple access, and/or MIMO wireless communications. In wireless communication systems that operate in supporting communications via one or more clusters, appropriate determination of when to begin making such transmissions on one or more clusters is made in accordance with intelligent carrier sense multiple access (CSMA) that may be performed in a number of different ways. In accordance with this, a cluster may be any combination composed of one or more channels among one or more bands. In supporting multi-cluster access, CSMA may be performed in selecting a primary cluster and performing backoff (e.g., countdown) thereon. After backoff is finished for the primary cluster, and the availability of one or more others clusters is checked, transmissions may be made using the available clusters. Alternatively, backoff may be made for each or multiple (a subset of) clusters or even individually for each respective cluster.

摘要： 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.

摘要： Frequency selective transmission within single user, multiple user, multiple access, and/or MIMO wireless communications. Adaptation among different respective sub-channels and/or channels is effectuated within a wireless communication system. Such a wireless communication system may include an access point (AP) and one or more wireless stations (STAs). The respective channelization employed for various communications between the devices within such a wireless communication system may be adapted based upon any of a number of considerations. For example, a receiver communication device may indicate to a transmitter communication device one or more preferred sub-channels and/or channels on which subsequent communications are to be performed. Alternatively, a transmitter communication device may employ such information provided from one or more receiver communication devices as one of multiple respective considerations regarding which one or more sub-channels and/or channels on which subsequent communications are to be performed.

摘要： Bandwidth mechanisms and successive channel reservation access within multiple user, multiple access, and/or MIMO wireless communications. A management frame, communicated from one wireless communication devices to one or more others, includes successive channel reservation assignment therein, and also indicates channel(s) within cluster(s) for use in respective communications (e.g., transmissions/receptions) of those wireless communication device(s) that receive the management frame. Subsequent management frames can modify or update such a channel assignment. Channel reservation for use in communications by respective wireless communication devices may be grown when additional channels may become available. Based on later determined information regarding the channel availability status, such channels that may become available can be used for subsequent, wider bandwidth communications. All communications include a primary channel (as indicated by a management frame, prior control frame, or other means) that may be located at a band edge or between respective channels (e.g., not at a band edge).

摘要： Multi-user uplink communications within multiple user, multiple access, and/or MIMO wireless communication systems. Within such communication systems, uplink communications from various receiving wireless communication devices (e.g., STAs) to a transmitting wireless communication device (e.g., AP) may occur in any of a number of various dimensions or combinations thereof including MU-MIMO dimension and frequency dimension (asynchronous FDM or synchronous FDM). In accordance with such uplink communications, various considerations such as time synchronization, frequency synchronization, and/or power control (including wireless communication device grouping). When performing uplink asynchronous FDM signaling, power control as grouping is used. When performing uplink synchronous FDM signaling, time synchronization, frequency synchronization, and power control (such as including wireless communication device grouping) is performed.

摘要： Beamforming feedback frame formats within multiple user, multiple access, and/or MIMO wireless communications. A transmitting wireless communication device (TX) transmits a sounding frame to one or more receiving wireless communication devices (RXs) using one or more antennae and one or more clusters. Any antenna/cluster combination may be employed in communications between TXs and RXs. The one or more RXs receive/process the sounding frame to determine a type of beamforming feedback frame to be provided to the TX. Any one of a variety of beamforming feedback frame types and a types of information may be contained within a respective beamforming feedback frame including various characteristics of the respective communication channel between the TX and each of the various RXs. A common beamforming feedback frame format may be supported and employed by all such wireless communication devices (e.g., TX and RXs) when performing MU-MIMO operation such as in accordance with IEEE 802.11ac/VHT.
