Abstract: 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.

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: 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: Session recovery after network coordinator or AP restart for single user, multiple user, multiple access, and/or MIMO wireless communications. Restart or reset of a network coordinator (e.g., an access point (AP) or other network coordinator type device) may occur for various reasons (e.g., a power cycle or power failure, inadequate failover protection, scheduled or planned power outages such as for including network maintenance, software upgrades, etc.). Upon determination of network coordinator restarted or reset, a singular bit within a communication from the network coordinator indicates synchronization or not of the its timing synchronization function (TSF) (e.g., with other devices in the communication system, such as wireless stations (STAs), smart meter stations (SMSTAs), etc.). A given device (e.g., STA, SMSTA, etc.) can provide its current TSF to the network coordinator so that it can resynchronize, re-establish its scheduled for wake times of those devices (e.g., target wake times (TWTs)), etc.

Abstract: 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.

Abstract: A wireless transceiver includes an antenna array that transmits an outbound RF signal containing outbound data to remote transceivers and that receives an inbound RF signal containing inbound data from the remote RF transceivers, wherein the antenna array is configurable based on a control signal. An antenna configuration controller generates the control signal to configure the antenna array to hop among a plurality of radiation patterns based on a hopping sequence. An RF transceiver section generates the outbound RF signal based on the outbound data and that generates the inbound data based on the inbound RF signal. In one configuration, a switching section selectively couples a selected one of the antennas in the array to the RF transceiver section, based on the control signal. In another configuration, the RF transceiver section includes an RF section for each antenna in the array.

Abstract: Techniques for localized dynamic channel allocation help meet the challenges of latency, memory size, and channel time optimization for wireless communication systems. As examples, advanced communication standards, such as the WiGig standard, may support wireless docking station capability and wireless streaming of high definition video content between transmitting and receiving stations, or engage in other very high throughput tasks. The techniques help to deliver the desired user experience in such an environment and address the need to meet latency and throughput requirements while limiting memory footprint.

Abstract: A system for oscillating a roller driven by rolling contact with a moving substrate. An oscillating assembly comprises first and second opposed gudgeons rotatably mounted on a shaft, the gudgeons being connected by either a plurality of rods or the roller. An oscillation mechanism comprises a reduction transmission assembly having differently toothed input and output pulleys. A cam groove in an oscillation cam is engaged by one or more oscillation pin(s) connected to the gudgeons. An input drive pulley turns with the gudgeons, and an output pulley turns with the oscillation cam. An intermediate double-pulley has second and third pulleys on a common hub. First and second timing belts connect, respectively, the input pulley to the second hub pulley, and the third hub pulley to the output pulley. A currently preferred step-down ratio between the input pulley and the output pulley is about 391:1.

Abstract: Smart meter media access control (MAC) for single user, multiple user, multiple access, and/or MIMO wireless communications. Different types of wireless communication devices may be implemented within various wireless communication systems. Some of these devices may be implemented to communicate sensing and/or measurement to one or more other devices. For example, certain devices may be implemented to perform monitoring associated with any of a number of services provided by service providers (e.g., electricity, natural gas, water, Internet access, telephone service, and/or any other service). In accordance with such sensing and/or measurement related applications, a given device need not necessarily be awake or at a fully operative state at all times. Appropriate coordination, scheduling, communication medium access, etc. among potentially many implemented devices ensures effective communication and gathering of such sensing and/or measurement related data (e.g.

Abstract: 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.

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 method for feeding back transmitter beamforming information from a receiving wireless communication device to a transmitting wireless communication device includes a receiving wireless communication device receiving a preamble sequence from the transmitting wireless device. The receiving wireless device estimates a channel response based upon the preamble sequence and then determines an estimated transmitter beamforming unitary matrix based upon the channel response and a receiver beamforming unitary matrix. The receiving wireless device then decomposes the estimated transmitter beamforming unitary matrix to produce the transmitter beamforming information and then wirelessly sends the transmitter beamforming information to the transmitting wireless device.

Abstract: Methods and formulations for forming a rolled cookie dough configuration for shipment, display and storage. The rolled configuration can be frozen and/or refrigerated and be subsequently unrolled prior to use. The cookie dough can be formulated so as to unroll into a flat sheet configuration without cracking, breaking and/or sticking together. When unrolled, the flat sheet configuration can be sliced/cut with cookie cutters to create specially shaped cookie units for baking. Excess dough can be trimmed and rerolled for further cutting with a cookie cutter.

Abstract: Device coexistence within single user, multiple user, multiple access, and/or MIMO wireless communications. Different respective communication devices operating using different respective communication channels having different respective channel bandwidths may be implemented within a given communication system. For example, different respective communication devices may belong to different basic services sets (BSSs) (e.g., a 1 MHz BSS operating using channel bandwidths of 1 MHz, and a 2 MHz BSS operating using channel bandwidths of 2 MHz). To effectuate coexistence among different respective devices operating using different respective channel bandwidths, devices but longing to the 1 MHz BSS monitor for and listen for 2 MHz wide communication activity, and those 1 MHz BSS communication devices defer to any detected communication activity on any portion of the 2 MHz channel.

Abstract: 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.
