摘要： 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.

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： Distributed signal field for communications within multiple user, multiple access, and/or MIMO wireless communications. In accordance with wireless communications, a signal (SIG) field employed within such packets is distributed or partitioned into at least two separate signal fields (e.g., SIG A and SIG B) that are located in different portions of the packet. A first of the SIG fields includes information that may be processed and decoded by all wireless communication devices, and a second of the SIG fields includes information that is specific to one or more particular wireless communication devices (e.g., a specific wireless communication device or a specific subset of the wireless communication devices). The precise locations of the at least first and second SIG fields within a packet may be varied, including placing a second of the SIG fields (e.g., including user-specific information) adjacent to and preceding a data field in the packet.

摘要： Time division multiple access (TDMA) media access control (MAC) adapted for single user, multiple user, multiple access, and/or MIMO wireless communications. Various com systems may include smart meter stations (SMSTAs) and/or wireless stations (STAs). Appropriate coordination is made with respect to such communication devices to ensure appropriate uplink (and/or downlink) communications between a network manager or coordinator (e.g., an access point (AP)) and the SMSTAs and/or STAs. With respect to SMSTAs, the relative duration of time that such communication devices are awake and operative versus asleep (or in a reduced power and/or functionality state) can be significant. Certain implementations may include a relatively large number of such communication devices (e.g., 10s, 100a, 1000s, or more), and appropriate coordination and scheduling of such communications to/from them is made using one or more variations of TDMA signaling (e.g., including different respective service periods (SPs), communication medium access operational modes, adaptation thereof, etc.).

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： Acknowledgment and/or receiver recovery mechanisms for scheduled responses within multiple user, multiple access, and/or MIMO wireless communications. Explicit scheduling information is provided from a first wireless communication device (e.g., an access point (AP), a transmitting wireless communication device) to a number of other wireless communication devices (e.g., wireless stations (STAs), receiving wireless communication devices) directing those other wireless communication devices a manner by which responses (e.g., acknowledgments (ACKs), block acknowledgments (BACKs), training feedback frames, etc.) are to be provided to the first wireless communication device there from. Such direction may include the order, timing, cluster assignment, etc. by which each respective wireless communication device is to provide its respective response to the first wireless communication device. In the event of the first wireless communication device failing to receive at least one response from at least one of the other wireless communication devices, various communication medium recovery mechanisms may be performed.

摘要： Management frame directed cluster assignment within multiple user, multiple access, and/or MIMO wireless communications. From a first wireless communication device, a management frame may be transmitted to a number of other wireless communication devices to assign respective clusters (i.e., cluster being one or more channels within one or more bands) for use in communications by those other wireless communication devices. The first wireless communication device may be an access point (AP), and the others may be wireless stations (STAs); alternatively, all of the wireless communication devices in the communication system (e.g., including the first wireless communication device) may be STAs. The cluster assignment may be modified for any of a number of various reasons (e.g., periodically, after a certain number of packets being transmitted and/or received, communication system operating condition change, change in number, type, capabilities, etc. of the various wireless communication devices in the communication system, etc.).

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.
