    Abstract: Systems and methods for capture, recording, and regeneration of subtle energy resonance signals are described herein. A system for capturing and recording the signals may include an antenna array disposed within an electromagnetic shield, a signal processor, and a memory coupled to at least one processor. The antenna array may include at least one antenna comprising a conductive disk and an amplifier circuit board, the antenna array detecting and receiving subtle energy resonance signals from a source. The signal processor converts the analog signals into digital signals, which are then stored into the memory.

  • Patent number: 10484949
    Abstract: Embodiments of the present disclosure provide an uplink power control method, a user equipment and a base station. The method comprises: receiving configuration information of a channel state information reference signal CSI-RS from the base station, wherein the configuration information of the CSI-RS comprises reference signal port information and reference signal power information; and measuring a path loss for uplink power control based on the configuration information of the CSI-RS. The embodiments of the present disclosure use the CSI-RS to measure the path loss, which differs from a common CRS in that the CSI-RS may aim at a specific base station. Therefore, path loss measurement may be performed in respect of a target base station of uplink transmission, enabling the path loss compensation to match the actual path loss, thus improving the performance of uplink power control.

Generally, any desired number of different dynamic ranges may be used at different times and based on different operating conditions. The communication device can include functionality associated with two or more transceivers to support communications based on two or more power modes (e.g., a full power mode, a reduced power mode or a sleep mode, etc.). The communication device may alternatively include two or more separate transceivers to support such communications.

    Abstract: A method and apparatus are provided by which a radio communication device with multi-watch receivers improves the comprehension of a high-priority message when the high-priority message is overlapped in time with a normal-priority message. A first receiver of the radio communication device receives a first incoming message over a first channel, and a second receiver of the radio communication device receives a second incoming message over a second channel. The radio communication device, upon receiving the first and second incoming messages, detects that a portion of the first incoming message overlaps in time with a portion of the second incoming message. The radio communication device further determines whether at least one of the first or the second incoming message is a high-priority message and repeats the determined high-priority message when at least one of the first or second incoming messages is a high-priority message.

  • Patent number: 8989817
    Abstract: Method and apparatus related to implementing and/or utilizing different polarization antennas with different corresponding average transmit power levels are described. Inter-cell interference is mitigated by having different cells with different power relationships between polarizations antennas. For example, a first base station transmits at a high average power level on its vertical polarization antenna and transmits at a low average power level on its horizontal polarization antenna. Concurrently, a second base station, which is adjacent to the first base station, transmits at a low average power level on its vertical polarization antenna and transmits at a high average power level on its horizontal polarization antenna. In some hexagonal deployment schemes a base station has at most two adjacent base stations using the same power level to antenna polarization direction relationship as it is using.

  • Patent number: 8982936
    Abstract: A system employing vector signal generator (VSG) and vector signal analyzer (VSA) modules or cards that are configured to test multiple devices under test simultaneously. Each VSG is configured to generate multiple RF test signals and send them to multiple devices under test simultaneously. Similarly, each VSA is configured with multiple signal receiving modules connected to a single controller or memory. Each signal receiving module receives an RF signal from a device under test, converts it to a baseband digital signal, and transmits this digital signal to the VSA's memory. A single RF testing system can employ multiple such VSGs and VSAs, each capable of evaluating multiple devices under test. Each VSG/VSA can further be tuned for operation in discrete or defined frequency bands, which are narrower than those for conventional RF testers, and which can correspond to various wireless standards.

  • Patent number: 8983413
    Abstract: Some embodiments of the present disclosure relate to multiband receivers that include at least one divider unit having a divisor that is other-than-two. For example, in some embodiments the divisor is an odd integer (e.g., three). Such divisors allow oscillators for respective receiver subunits in a multi-band receiver to have frequencies that are sufficiently different from one another so as to limit cross-talk interference there between, even when the receiver subunits are concurrently receiving data on adjacent channels. To facilitate this other-than-two divisor, a phase error compensation block is often used to compensate for the effects of using the other-than-two divisor.

  • Patent number: 8976732
    Abstract: A control unit, in cooperation with an interface (IF) unit, a modulation unit and a baseband processing unit, produces a packet signal composed of a plurality of streams. While using as a reference a first known signal assigned to one of the plurality of streams and performing a cyclic timing shift within the first known signal on a first known signal assigned to another stream, the control unit performs a timing shift also on an extensional known signal assigned to a stream where no data is assigned. The amounts of timing shift are given degrees of priority beforehand and for the stream where data signals are assigned the control unit uses the amounts of timing shift in descending degree of priority. For the stream where no data signal is assigned, the control unit uses the amounts of timing shift also in descending degree of priority.

  • Patent number: 8964873
    Abstract: The signaling amount in selecting a plurality of beams is reduced in pre-coding to enhance throughput. When notification of a beam number is provided in a feedback signal from an user equipment to a radio base station, a superior beam number, having a high quality rank with small time variation, is bound up and fixed for a predetermined time period and notification of only a inferior beam number is provided within the predetermined time period. For example, to select three beams among six beams, first, notification of the superior two beam numbers (beam numbers ‘b’ and ‘c’) is provided. These beam numbers are fixed for a predetermined time period and then notification of only the inferior one beam number (beam number ‘e’) is provided within the predetermined time period. Thus, the signaling amount for providing beam number notification is reduced.

  • Patent number: 8953702
    Abstract: A process selects a Precoding Matrix Index (PMI) in a Multiple In Multiple Out (MIMO) receiver used in a wireless communications system including a base station communicating with User Equipments (UE) through a downlink and uplink channel. The base station applies a precoding on the transmit symbol vector based on a matrix selected from a set of predefined matrices and identified by a PMI index computed by the UE and forwarded to the base station via the uplink. The process includes estimating the MIMO channel matrix H of a given set of resources blocks comprising received symbol vectors, estimating the variance ?2 of the additive noise (AWGN), and computing for each particular matrix comprised within the set of predefined matrices a cost function representative of the orthogonality of the matrix MIMO channel matrix H.
