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 support desired performance levels for latency and throughput while controlling memory footprint.

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: 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 group 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. The operational parameters govern the manner in which at least a portion of the subsequently transmitted packet is processed.

Abstract: A communication device includes a processor configured to generate OFDMA packets using various OFDMA packet structures and to transmit such OFDMA packets, via a communication interface, to at least one other communication device. The processor is also configured to receive, interpret, and process such OFDMA packets. One example of an OFDMA packet includes common SIG for two or more other wireless communication devices modulated across all sub-carriers of the OFDMA packet. The common SIG is followed by first SIG and first data for a first other wireless communication device modulated across first subset of the sub-carriers of the OFDMA packet and is also followed by second SIG and second data for a second other wireless communication device modulated across second subset of the sub-carriers of the OFDMA packet. Another example of an OFDMA packet includes the common SIG followed directly by first data and second data modulated as described above.

Abstract: A relay wireless communication device is implemented to perform buffer management and coordination with a source wireless communication device. A relay wireless communication device (generally, a relay) informs a source wireless communication device (source) of the status of memory therein to store messages intended for a destination wireless communication device (destination). For example, the source transmits information to the relay, which buffers information before forwarding it on to the destination. This buffering may be a function of the source having additional information intended for the relay and/or destination. The relay performs appropriate signaling, such as suspend transmission requests and resume transmission requests, to inform other devices in the system of its memory storage status (e.g., such as when having an actual or anticipated overflow). In one implementation, a suspend transmission request may be implemented by setting a particular bit within a communication from the relay to the source.

Abstract: 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.

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: 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.
