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: LDPC coding systems for 60 GHz millimeter wave based physical layer extension. LDPC (Low Density Parity Check) encoding in cooperation with sub-carrier interleaving, in the context of orthogonal frequency division multiplexing (OFDM), and appropriate symbol mapping is performed in accordance with transmit processing as may be performed within a communication device. In a receiving communication device, receive processing may be performed on a received signal based on the type of LDPC, sub-carrier interleaving, and symbol mapping thereof. The LDPC code employed in accordance with such LDPC encoding may have a partial-tree like structure. In addition, appropriate manipulation of the bits assigned to respective sub-carriers may be performed to ensure that the bits emplaced in the MSB (Most Significant Bit) location of various symbols has some desired diversity (e.g., from different codewords, from appropriately different locations within a given codeword, etc.).

Abstract: Transmission coordination within multiple user, multiple access, and/or MIMO wireless communications. Within wireless communication systems, there can be various wireless communication devices therein that are not all compliant with a common capability set, communication protocol, communication standard, recommended practice, etc. For example, some communication systems may have some wireless communication devices characterized as ‘legacy’ wireless communication devices, and other wireless communication devices therein may be newer and compliant with newer capability sets, communication protocols, communication standards, recommended practices, etc. In such instances, coordination of transmissions among the various wireless communication devices may be made, when performing simultaneous transmissions, by ensuring that transmissions of devices on different channels is made when aligned on a common boundary of an OFDM symbol. Alternatively, such simultaneous transmissions may be made when offset by some multiple of OFDM symbol duration. When performing non-simultaneous transmissions, transmissions may be made based on channel availability.

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 antennas to receive a first signal from a remote device, wherein the first signal corresponds to a first operational mode. A baseband processor selects either a first operational mode for transmitting a second signal or a second operational mode for transmitting the second signal. When the second operational mode is selected the baseband processor transforms the phase-related information corresponding to the first operational mode to transformed phase-related information corresponding to the second operational mode. The antennas transmit the second signal to the remote device in accordance with the transformed phase-related information corresponding to the second operational mode.

Abstract: 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.

Abstract: A method and system for communicating feedback information in a multiple user multiple input multiple output (MU-MIMO) communication system are presented. In one aspect of the method and system, a beamformer station may communicate a feedback information request to a plurality of beamformee stations. The feedback information request may request feedback data for a plurality of RF channel bands. The RF channel bands may form a multichannel. The beamformer may subsequently transmit a plurality of signals utilizing the RF channel bands within the multichannel. Each of the beamformees may receive the plurality of subsequently transmitted signals. A beamformee may generate the requested feedback data for each RF channel band within the multichannel. The beamformee may generate a beamforming report, which comprises the feedback data, which is generated across the plurality of RF channel bands in the multichannel. The beamformee may transmit the beamforming report to the beamformer.

Abstract: Hybrid multi-cell channel estimation. At least two different operational modes associated with performing multi-cell channel estimation are combined and performed within different respective iterations of processing in order to generate a multi-cell channel estimate. A device, including at least one wireless interface to support communications with at least one other device and also including at least one processor to process signals received by or to be transmitted from, is operative to generate a multi-cell channel estimate corresponding to two or more respective cells with which the device may communicate. A first operational mode corresponds to time domain (TDOM) based per-tap serial interference cancellation (SIC), and a second operational mode corresponds to frequency domain (FDOM) based per-cell SIC. One implementation operates with no more than one iteration of TDOM based per-tap SIC, and no more than two iterations of FDOM based per-cell SIC.
