摘要： A method for multiple protocol wireless communications begins by determining protocols of wireless communication devices within a proximal region. The method then continues by determining whether the protocols of the wireless communication devices within the proximal region are of a like protocol. The method continues by, when the protocols of the wireless communication devices within the proximal region are not of a like protocol, selecting a protocol of the protocols of the wireless communication devices within the proximal region based on a protocol ordering to produce a selected protocol. The method continues by utilizing the selected protocol by the wireless communication devices within the proximal region to set up a wireless communication within the proximal region.

摘要： Target wake time (TWT) within single user, multiple user, multiple access, and/or MIMO wireless communications. Within communication systems including different respective devices therein (e.g., wireless stations (STAs), smart meter stations (SMSTAs), etc.), coordination is made with respect to those devices awakening from less than full power state (e.g., from sleep, reduce functionality, power saving state, etc.). A TWT information element (IE) may be included within a frame or a signal corresponding to or based on that frame that is transmitted from one device to other device(s). One or more respective future targeted times (e.g., which may be based on a timing synchronization function (TSF) reference time) at which device(s) may awaken from less than full power state may be included within the TWT IE. Over time, different respective TWT IEs may be provided from various devices, such that respective targeted awake times may be modified dynamically for any given device.

摘要： One or multiple bit restricted access window (RAW) end point determination within for single user, multiple user, multiple access, and/or MIMO wireless communications. A RAW is defined in which only devices of the particular class (e.g., low power class, Z class, smart meter station (SMSTA) class, etc.) are allowed access to the communication medium. Indication of the end of such a RAW may be included within one or more bits set within a signal field (SIG) field of a framer packet generated by a given device within the system and transmitted to one or more other devices. After completion of the RAW, other respective devices of at least one other type of class may be provided access to the communication medium. The manner of access to the communication media outside of the RAW may be varied (e.g., scheduled, based on carrier sense multiple access/collision avoidance (CSMA/CA), etc.).

摘要： Aggregated fragment acknowledgement in a LAN. A transmitter sends a data packet to a receiver. The receiver then constructs an AFAF and sends that AFAF back to a transmitter. The transmitter is then able to determine the success and/or failure, in full or in part, of the transmission of the data packet to the receiver. A very precise granularity, or resolution, of the success of the transmission may be achieved on a per fragment basis. Bandwidth savings may also be achieved. When no resolution on a fragment basis is required, then that level of resolution is not employed. The resolution of the fragment basis may be adaptively employed when required to notify the transmitter of the status of one or more fragments within a data packet.

摘要： A method of providing synchronous transport of packets between asynchronous network nodes. An asynchronous network node capable of transmitting and receiving packetson the asynchronous network is designated as a master node. Each non-master asynchronous network node which desires to synchronously transport packets across the asynchronous network is designated as a slave node. Best arrival times for packets transmitted from slave nodes to the master node are communicated from the master node to the slave nodes. Bestpacket assembly times for packets to be transmitted by the particular slave node to the master node in the future for the packets to be received by the master node at future master clock referenced best arrival times are determined. Packets for transmission at slave nodes are prepared and transmitted according to determined future bestpacket assembly time information.

摘要： A method for generating a preamble of a frame for a multiple input multiple output (MIMO) wireless communication begins by, for each transmit antenna, generating a carrier detect field. The method continues by, for a first grouping of the transmit antennas, generating a first guard interval following the carrier detect field; and generating at least one channel sounding field. Continuing, the method applies cyclical shift prior to transmission via the first grouping of the transmit antennas. When the MIMO wireless communication includes more than the first grouping of the transmit antennas, for another grouping of the transmit antennas. For the another grouping of the transmit antennas, generating at least one other channel sounding field. The method proceeds by generating the first guard interval prior to the at least one other channel sounding field, and applying another cyclical shift prior to transmission via the another grouping of the transmit antennas.

摘要： Differential feedback within multiple user, multiple access, and/or MIMO wireless communications. After full feedback signal(s) have been received by a communication device (e.g., one that is to be performing beamforming for use in subsequent signal transmission), differential feedback signal(s) are received. Those differential feedback signal(s) are employed to update the full feedback signal(s) thereby generating updated/modified full feedback signals. Over time, such updated/modified full feedback signals may subsequently be further updated based upon later received inferential feedback signal(s). Such differential feedback signaling takes advantage of time and/or frequency correlation in a communication channel to provide for reduced feedback overhead by feeding back a difference or delta (Δ) relative to a previous value. For example, instead of providing full feedback signals in each respective/successive communication, feedback overhead is reduced by providing a difference or delta (Δ).

Various communications are made between an originating communication device and a remote communication device to effectuate steered communications there between. The beamforming approach presented herein is applicable and adaptable to communication devices having any combination of omni-directional and directional transmit and receive functionality (e.g., the transmit functionality and the receive functionality both being omni-directional; the transmit functionality being directional and the receive functionality being omni-directional; or the transmit functionality and the receive functionality both being are directional). The beamforming protocol presented herein allows for all combinations of communication device types and also provides collision rules as may be performed in accordance with the beamforming configuration.

摘要： A Wireless Local Area Network (WLAN) supports multiple slot times. A Basic Service Set (BSS)/Independent Basic Service Set (IBSS) of the WLAN services a plurality of WLAN devices (STAs) and at least one STA of the plurality of STAs supports multiple slot times. Operation is initiated using a short slot time. Then, the a determination is made that operation of the BSS/IBSS requires use of a long slot time, wherein the long slot time is longer than the short slot time. Operation of at least one of the plurality of STAs is modified to be consistent with the long slot time. In altering the operation the STA sets a local Long Slot Termination Time (LSTT). When a Target Beacon Transition Time (TBTT) is before the local LSTT, a beacon is transmitted that indicates that the long slot time is to be used and that includes the local LSTT. When the TBTT is after the local LSTT, a beacon is transmitted that indicates that the short slot time is to be used.
