  • Patent number: 9531761
    Abstract: An IP multimedia gateway (IMG) determines device capabilities and proposed service priority profiles of communicatively coupled client devices. The determined device capabilities and proposed service priority profiles are transmitted to service managers for service scheduling. Device capabilities of the communicatively coupled client devices are configured or prioritized based on available actual service priority profiles from the service managers. The configured device capabilities are transmitted to the service managers for subsequent service scheduling. Services provided by the service managers are announced based on the available actual service priority profiles. The IMG communicates content for the announced services between the communicatively coupled client devices and the service managers. The IMG may allow the user of a client device to access desired content via other client devices.

  • Patent number: 9532245
    Abstract: Disclosed are apparatuses, methods and computer program instructions which receive or detect an in-device coexistence interference condition change in a user equipment equipped with a plurality of transceivers, send an indication of the in-device coexistence interference condition change to an access point and receive a media access control element configured for muting/unmuting at least one of a plurality of transceivers from the access point. The condition of in-device coexistence interference relates to interference among transceivers such as a long term evolution advanced transceiver and a Bluetooth transceiver in the same user equipment. The media access control element can be configured to either promote a measurement gap pause or short discontinuous transmission during a condition of in-device coexistence interference.

  • Patent number: 9532237
    Abstract: In a communications network with carrier aggregation (CA), embodiments enable the network to advertise to a supported wireless device not only whether or not aggregated component carriers allocated to the wireless are intra-band adjacent but further whether or not the allocated component carriers are collocated. Embodiments further enable the wireless to advertise its CA capabilities including the support of adjacent collocated CA and/or non-adjacent collocated CA. Embodiments thus provide systems/methods for the exploitation of special conditions provided by adjacent collocated component carriers to reduce processing complexity and power consumption for certain types of wireless device transmitter/receiver architectures and to support intra-band adjacent CA for other types of UE transmitter/receiver architectures.

  • Patent number: 9532256
    Abstract: Embodiments include systems and methods for improving the beamforming efficiency of Multi-User Multiple Input Multiple Output (MU-MIMO) and/or Coordinate Beamforming (CB) in wireless multi-access networks. In one aspect, a receiver-aided approach for MU-MIMO and/or CB is provided. Unlike conventional MU-MIMO/CB operation which is transparent to the UE, the receiver-aided approach herein makes information about potential MU-MIMO and/or CB multi-user interference available to UEs being considered for MU-MIMO and/or CB transmission. As such, the UEs can provide Channel State Information (CSI) that is better tailored to actual data transmission conditions than in conventional operation, and the base station can make better decisions regarding MU-MIMO and/or CB operation, user selection, and transmission parameters (e.g., number of data streams, precoder matrix, etc.).

  • Patent number: 9525639
    Abstract: Transceiver architecture includes circuitry and a method to transmit and receive high speed WAP data over lower speed cabling such as Cat5e. The method begins by measuring quality of a wired bi-directional communications channel. The method continues by selecting a maximum possible data transmission rate over the wired bi-directional communications channel for the measured quality level and when the maximum possible data transmission rate is a reduced data transmission rate less than a maximum data transmission rate of the transceivers, proportionally adjusting clock rates of circuit elements of the first and second transceiver to transfer the data at the reduced data transmission rate. The method includes dividing data frames of the data to be transmitted N times, where N=number of layers of at least a portion of identical transceiver processing circuitry which is connected to twisted wiring pairs of the wired bi-directional communications channel.

  • Patent number: 9525447
    Abstract: Because of associated disadvantages of narrow-band off-chip radio-frequency (RF) filtering, a mixer-first receiver front-end designed to tolerate blockers with reduced gain compression and noise factor degradation is disclosed. The mixer-first receiver front-end includes two separate down-conversion paths that help to reduce added noise and voltage gain prior to baseband filtering, which are critical factors in eliminating narrow-band off-chip RF filtering. The mixer-first receiver front-end can be used to support down-conversion of multiple different communication signals (e.g., cellular, WLAN, and WPAN communication) with different center frequencies.

  • Publication number: 20160365873
    Abstract: The present disclosure is directed to an apparatus and method for decoding non-binary LDPC codes over non-associative finite division near rings. A non-associative finite division near ring is a type of algebraic structure that includes a finite set of elements on which the operations of addition and multiplication are defined. The operation of addition is commutative, associative, and closed, and may have an additive identity for all elements in the finite set. The operation of multiplication is closed but not commutative or associative, and has a multiplicative inverse but not a multiplicative identity for all elements in the finite set. The two operations of addition and multiplication may be related by the distributive property.

  • Patent number: 9521268
    Abstract: A wireless communication device communicating with a serving base station in a wireless communication environment may have one or more applications running. When seeking to handover from the serving base station to a target base station, the wireless communication device adjusts the configurations of the applications based on the new communication link properties. Likewise, when an application is loaded that prefers communication link properties that exceeds a current communication link's capabilities, the wireless communication device may seek out and hand over to other communication links. By cooperatively coordinating the functionality of installed applications with communication link properties, the wireless communication device can maintain high levels of device and application functionality.

  • Patent number: 9520889
    Abstract: A frequency synthesizer includes circuitry configured to generate two or more feedback clocks based on the oscillation signals output from a voltage-controlled oscillator. The circuitry also modulates the feedback clocks based on fractional offsets from a reference clock frequency for input into two or more phase and frequency detectors. Multiple charge pump circuits receive inputs from these phase and frequency detectors. The current from these charge pumps is summed and input to a low pass filter. The output of the filter represents an average of the time difference between the reference clock and the multiple feedback clocks.

  • Patent number: 9520194
    Abstract: A pre-computation based TCAM configured to reduce the number of match lines being pre-charged during a search operation to save power is disclosed. The pre-computation based TCAM stores additional information in a secondary TCAM that can be used to determine which match lines in a primary TCAM storing data words to be searched need not be pre-charged because they are associated with data words guaranteed to not match. The additional information stored in secondary TCAM can include a pre-computation word that represents a range inclusive of a lower and upper bound of a number of ones or zeroes possible in a corresponding data word stored in the primary TCAM.
