  • Patent number: 9391577
    Abstract: In a variable gain amplifier, a base of a bipolar first transistor receives a first differential input signal. The emitter of the first transistor is connected in series between a first resistor and a MOSFET coupled to ground. An output of the amplifier is a current through the collector. The conductivity of the MOSFET controls a gain of the amplifier. A bipolar second transistor receives a second differential input signal, and the second transistor provides a modulated gate voltage to the MOSFET. The drain voltage of the MOSFET is modulated by the first differential input signal and thus undesirably generates distortion. To reduce the distortion, the modulated gate voltage causes the AC component for a certain DC voltage at the drain of the MOSFET to be lowered, improving linearity. Since no current source is used, the amplifier has a large headroom, allowing operation using a low operating voltage.

  • Patent number: 9008115
    Abstract: Data streams stored in buffers are modulated by modulation sections. Multipliers multiply the signals output from the modulation sections by weights output from a weight control section. The signals output from the multipliers are added up by addition sections, subjected to radio transmission processing by transmission radio sections and sent through antennas. A buffer control section controls the buffers based on a retransmission count output from a retransmission count detection section. The weight control section outputs weights different from weights at the time of previous transmission to the multipliers every time data is retransmitted. This allows a diversity gain at the time of data retransmission to be increased even if a time variation of the propagation path environment for radio signals is slow.

  • Patent number: 8934405
    Abstract: In one embodiment, a method of scheduling transmissions for a base station in a multi-carrier wireless communication network comprises scheduling initial transmissions of data packets for one or more users on a first carrier, without reserving scheduling capacity on the first carrier for retransmissions. Doing so increases the scheduled capacity of the first carrier for initial transmissions. The method further includes scheduling retransmissions, as needed, for given ones of the data packets on one or more second carriers. The method allows more traffic to be scheduled on the first carrier, meaning that multi-carrier transmissions are less frequently needed to convey all of the traffic targeted to one or more receivers. Those receivers therefore spend more time operating with a reduced receiver bandwidth (as compared to the bandwidth required for receiving more than one carrier), which reduces operating power.

  • Patent number: 8842585
    Abstract: When a common search space and a user equipment-specific search space overlap with each other, and bit numbers of DCI formats transmitted in the common search space and the user equipment-specific search space, respectively are the same as each other, a mobile station apparatus identifies a type of the DCI format. When the common search space and the user equipment-specific search space overlap with each other, and a bit number of a DCI format allocated in the common search space and a bit number of a DCI format allocated in the user equipment-specific search space are the same as each other, a base station apparatus does not allocate the DCI format allocated in the user equipment-specific search space in the overlapped space, and a mobile station apparatus performs blind decoding only of the DCI format allocated in the common search space in the overlapped space.

  • Patent number: 8787291
    Abstract: A wireless communication base station apparatus wherein when a frequency scheduling transmission and a frequency diversity transmission are performed in a multicarrier communication at the same time, the adaptive control of a channel for performing the frequency scheduling transmission can be prevented from being complicated. In this apparatus, a modulating part modulates an encoded Dch data to generate Dch data symbols. A modulating part modulates an encoded Lch data to generate Lch data symbols. An assigning part assigns the Dch and Lch data symbols to subcarriers constituting OFDM symbols and outputs them to a multiplexing part. At this moment, the assigning part assigns a set of Dch and Lch data symbols to each subcarrier for a respective subband.

  • Patent number: 8750325
    Abstract: Data streams stored in buffers are modulated by modulation sections. Multipliers multiply the signals output from the modulation sections by weights output from a weight control section. The signals output from the multipliers are added up by addition sections, subjected to radio transmission processing by transmission radio sections and sent through antennas. A buffer control section controls the buffers based on a retransmission count output from a retransmission count detection section. The weight control section outputs weights different from weights at the time of previous transmission to the multipliers every time data is retransmitted. This allows a diversity gain at the time of data retransmission to be increased even if a time variation of the propagation path environment for radio signals is slow.

  • Patent number: 8743913
    Abstract: A distributed DSLAM, which comprises a head end subsystem located within a switching facility and a remote subsystem located outside of the switching facility. The head end subsystem is operative for routing streams of data from a data network to the remote subsystem over a communication link, while the remote subsystem is operative for transmitting over a set of local loops analog signals comprising digitally modulated versions of the data. Separating the routing and modem functionality between inside and outside plant facilities reduces heat dissipation in the outside plant, leading to increased reliability. Flow control can be performed in the upstream and downstream directions by transmitting portions of individual packets and withholding other portions of individual packets. This is done instead of withholding the transmission of entire packets. As a result, the perceived impact on video quality, for example, is lessened.

  • Patent number: 8611868
    Abstract: A wireless communications network includes roving subscriber-stations and base stations receiving broadcast programs from a content server. A subscriber-station evaluates whether a desired program is available from a subject base station. According to this evaluation, the subscriber-station takes steps to (1) receive the desired program on a shared channel for reception by multiple subscriber-stations, or (2) initiate base station delivery of the desired program to the subscriber-station on an individual channel. Responsive to a message from a subject subscriber-station identifying a desired program, a base station either (1) continues transmitting the desired program upon a shared channel, (2) starts transmitting the desired program on a shared channel, or (3) sends the subject subscriber-station a channel assignment message and commences transmission of the desired program on the assigned individual channel.
