    摘要: A technique for dynamic spectrum sharing includes identifying (705) a plurality of radio nodes (115, 120), measuring (710) a local signal value (SV) at each radio node (110, 200), and determining (715) a transmit decision. Each radio node can measure a local signal value (SV) of a protected transmission and the radio nodes are within a uniform SV region of the protected transmission. The transmit decision is determined for at least one of the plurality of radio nodes based on the SV of each radio node in the plurality of radio nodes and at least one threshold value that is related to statistical characteristics of the protected transmission at an interference boundary (105) of the protected transmission and a desired probability of non-interference with the protected transmission at the interference boundary.

    摘要: A DTV signal detector detects DTV signals received by a receiver on a selected DTV channel in a Digital Television System. The DTV detector includes a first DTV signal detector that detects a first characteristic of the received DTV signals, and a second DTV signal detector that detects at least a second characteristic of the received DTV signals. A controller responds to the first DTV signal detector and the second DTV signal detector to control a selection of the DTV channel being selected by the receiver. The receiver can be synthesized to select from more than one DTV channel.

    摘要: A communication system employs a HARQ-type retransmission scheme. Bits (701) received on a first transmission are stored and combined with the bits received on later transmissions thereby increasing the likelihood of a correct decoding on later transmissions. Similarly the bits received on the second or later transmissions are stored for combining with subsequent received bits. Specific information needed at the receiver is identified and requested from the transmitter. More particularly, information that is retransmitted in a second or later transmission in the HARQ scheme is determined from a reliability of individual constituent bits in the mother codeword or from an overall reliability of the received codeword. Based on these reliability metrics, the most unreliable set of the constituent bits are requested or, in the alternative, a specific number of constituent bits is requested.

    摘要: Methods, apparatuses and computer-readable storage media perform phasing of a first array including one or more antenna elements and phasing of a second array including one or more antenna elements to provide a combined radiation pattern for the first and second arrays, the first array having a first radiation pattern and the second array having a second radiation pattern, wherein the first radiation pattern is substantially orthogonal to the second radiation pattern. The combined radiation pattern is controlled in a first dimension based upon an uplink channel measurement. The combined radiation pattern is controlled in a second dimension based upon a precoding feedback from a user equipment (UE).

    摘要: A method and apparatus for providing channel feedback is provided herein. During operation a covariance matrix at time t (R) is calculated as a function of a received downlink signal. Matrix Ct is also calculated and is based on a previous quantized covariance matrix (Rqt-1), the covariance matrix (R) at time t, and a forgetting factor (γ) that is applied to Rqt-1. The Ct is then used to create a DERC feedback message (signal or waveform) and may be transmitted with pilots on a proper feedback channel to a base unit. The base unit receives the feedback (Ct) as a DERC waveform on a proper feedback channel. The base unit uses non-coherent or coherent detection to detect the DERC values send by the remote unit and uses the DERC values with a previous quantized covariance matrix estimate, a forgetting factor, and a weighting value to compute a covariance matrix estimate to use for beamforming. The base unit then uses the covariance matrix estimate to determine appropriate channel beamforming weights, and instructs transmit beamforming circuitry to use the appropriate weights.
