  • Publication number: 20220240239
    Abstract: A method and apparatus may be used to support coordinated and cooperative sectorized transmissions. Power control and clear channel assessment for sectorized transmissions may be used, along with sectorized beacon and associated procedures. Transmissions in a network may be protected by a first access point (AP) sending an omni-directional transmission and a beamformed or sectorized transmission to a station (STA), an overlapping basic service set (OBSS) confirming a spatially orthogonal (SO) condition based on the omni-directional transmission, and a second AP monitoring the omni-directional transmission and confirming the SO condition. The STA may be configured to receive a request-to-send (RTS) frame indicating data is available for transmission, and transmit a cooperative sectorized (CS) clear-to-send (CTS) frame indicating an ability for multiple AP reception.

  • Patent number: 11047997
    Abstract: A radiation imaging system images a distributed source of radiation from an unknown direction by rotating a scatter mask around a central axis. The scatter mask has a pixelated outer surface of tangentially oriented, flat geometric surfaces that are spherically varying in radial dimension that corresponds to a discrete amount of attenuation. Rotation position of the scatter mask is tracked as a function of time. Radiation counts from gamma and/or neutron radiation are received from at least one radiation detector that is positioned at or near the central axis. A rotation-angle dependent detector response curve (DRC) is generated based on the received radiation counts. A reconstruction algorithm for distributed radiation source(s) and/or localized source(s) are applied based on the tracked rotation position and prior characterization of the detector response for a given scatter mask. A two-dimensional image with relative orientation and source distribution is generated from the measured DRC.

  • Publication number: 20110142107
    Abstract: Systems and methods for generating a demodulation reference signal for use by user equipment configured with multiple antennas based on a rank of an antenna or an antenna port are disclosed. A rank for a user equipment device is determined indicating the number of spatial layers or antenna ports in use, and the value of the rank is used to generate a cyclic shift offset and a cyclic shift, that can then be used to generate a demodulation reference signal to be used in timeslots within each spatial layer of an uplink transmission. Orthogonal cover codes may be used in conjunction with a determined cyclic shift to generate a demodulation reference signal.

  • Publication number: 20080081655
    Abstract: A combined open loop and closed loop (channel quality indicator (CQI)-based) transmit power control (TPC) scheme with interference mitigation for a long term evolution (LTE) wireless transmit/receive unit (WTRU) is disclosed. The transmit power of the WTRU is derived based on a target signal-to-interference noise ratio (SINR) and a pathloss value. The pathloss value pertains to the downlink signal from a serving evolved Node-B (eNodeB) and includes shadowing. An interference and noise value of the serving eNodeB is included in the transmit power derivation, along with an offset constant value to adjust for downlink (DL) reference signal power and actual transmit power. A weighting factor is also used based on the availability of CQI feedback.

  • Publication number: 20070291868
    Abstract: The present invention is a method and apparatus for improving the performance of spatial temporal turbo channel coding (STTCC) used in multiple-input multiple-output (MIMO) wireless communication systems called eigen-STTCC (E-STTCC) that employs eigen-beamforming to make use of orthogonal eigen streams in the MIMO channel. Singular value decomposition (SVD) is applied to the channel matrix producing a linear precoding matrix containing the orthonormal basis for the eigen streams. In a first embodiment, the turbo encoded codeword containing concatenated systematic and parity bits is precoded with the linear precoding matrix such that the systematic bits are transmitted over the eigen streams with highest power. In a second embodiment, the codeword is made up of interleaved systematic bits and parity bits prior to eigen beamform preceding, effectively interleaving the systematic and data bits spatially over the eigen streams.

  • Publication number: 20070260956
    Abstract: A method and system for supporting multiple hybrid automatic repeat request (H-ARQ) processes per transmission time interval (TTI) are disclosed. A transmitter and a receiver include a plurality of H-ARQ processes to transmit and receive multiple transport blocks (TBs) simultaneously per TTI. The transmitter generates a plurality of TBs and assigns the TBs to multiple H-ARQ processes. The transmitter sends control information for the TBs and H-ARQ processes associated with the TBs to the receiver. The transmitter then sends the TBs using multiple H-ARQ processes simultaneously per TTI. After receiving the TBs, the receiver sends feedback to each of the TBs indicating successful or unsuccessful receipt of each of the TBs to the transmitter. The control information and the feedback may be sent via a layer 1 or layer 2/3 control part.

  • Publication number: 20070211822
    Abstract: A method and apparatus for implementing spatial processing with unequal modulation and coding schemes (MCSs) or stream-dependent MCSs are disclosed. Input data may be parsed into a plurality of data streams, and spatial processing is performed on the data streams to generate a plurality of spatial streams. An MCS for each data stream is selected independently. The spatial streams are transmitted via multiple transmit antennas. At least one of the techniques of space time block coding (STBC), space frequency block coding (SFBC), quasi-orthogonal Alamouti coding, time reversed space time block coding, linear spatial processing and cyclic delay diversity (CDD) may be performed on the data/spatial streams. An antennal mapping matrix may then be applied to the spatial streams. The spatial streams are transmitted via multiple transmit antennas. The MCS for each data stream may be determined based on a signal-to-noise ratio of each spatial stream associated with the data stream.

  • Publication number: 20070211815
    Abstract: A method and apparatus for scaling a soft bit for decoding in a wireless communication system are described. A scaling factor is calculated for a received symbol based on an estimated signal-to-noise ratio (SNR) of the received symbol and the scaling factor is applied to a soft bit of the received symbol. A multiple-input multiple-output (MIMO) scheme may be implemented to transmit multiple data streams. In such case, a soft bit of a received symbol on each data stream is scaled by a scaling factor for the received symbol on each data stream.
