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： Scheduled clear to send (CTS) for multiple user, multiple access, and/or MIMO wireless communications. Before sending transmissions, a request to send (RTS)/clear to send (CTS) exchange takes place between a transmitting wireless communication device and multiple receiving wireless communication devices may take place therein. The transmitting wireless communication device (e.g., an AP) may generate and transmit a multi-user request to send (mRTS) frame to a number of receiving wireless communication devices (e.g., STAs). The mRTS frame can include information and instructions therein to direct the manner by which all or a subset of the receiving wireless communication devices are to provide CTS responses back to the transmitting wireless communication device. The mRTS frame may be an OFDMA frame, a MU-MIMO frame, or a combination thereof. The CTS responses may be received in accordance with any one or combination of OFDM signaling, OFDMA signaling, and MU-MIMO signaling.

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： Group identification and definition within multiple user, multiple access, and/or MIMO wireless communications. A group identification definition field may be transmitted to a number of receiving devices for use in interpreting current or subsequently received packets that include a group identification field (group ID). The group ID can serve a number of functions such as indicating those receiving devices for which the packet is intended, the identification of fields within the packet corresponding to the various devices, certain parameters (e.g., code type, code rate, modulation type, etc.) associated with such fields within the packet, etc. The group identification definition field may be updated or modified to allow for modification of the manner in which subsequent packets, including respective group IDs, are processed. One of a variety of events may direct the group identification definition field may be updated or modified.

摘要： 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.

摘要： Management frame map directed operational parameters within multiple user, multiple access, and/or MIMO wireless communications. A management frame map may be generated within and transmitted from a first wireless communication device to a number of other wireless communication devices. Thereafter, certain subsequently transmitted packets may be analyzed and processed by the receiving wireless communication devices based on that earlier received management frame map. One or more operational parameters are determined for a subsequently transmitted packet based on the previously received management frame map; such operational parameters then govern the manner in which at least a portion of the subsequently transmitted packet is processed. Some examples of such operational parameters include a cluster on which a least a portion of the packet is transmitted, a modulation coding scheme (MCS), a forward error correction (FEC) coding scheme, space time block coding (STBC), an antenna configuration within the wireless communication device, etc.

摘要： Transmission acknowledgement within multi-user wireless communication systems. Within multi-access wireless communication systems such as those operating in accordance with multi-user multiple input multiple output (MU-MIMO), orthogonal frequency division multiple access (OFDMA), and/or MU-MIMO/OFDMA, acknowledgement of receipt (e.g., using ACKs) is provided back to the sending or transmitting wireless communication device from each (or a subset) of the intended recipient wireless communication devices. Appropriate coordination of these ACKs from the respective, receiving wireless communication devices may be performed using instructions embedded within a multi-user packet that is provided to the receiving wireless communication devices. Alternatively, polling as effectuated by the sending or transmitting wireless communication device may be used to give explicit direction to the respective, receiving wireless communication devices of the manner by which their respective ACKs should be provided to the transmitting wireless communication device.
