Abstract: Methods and systems for distributed infrastructure for streaming data via multiple access points. Aspects of one method may include apportioning multimedia information among a plurality of transmitting devices based on feedback channel information received from a destination receiving device by, for example, a transmission controller device. The transmitting devices may transmit the multimedia information to the destination receiving device. A transmitting device that may not be apportioned multimedia information may transmit a probing signal. The destination receiving device may generate feedback channel information for a transmitting device, for example, based on the multimedia information or the probing signal received from the respective transmitting device. The apportioning of the multimedia information may be dynamically adjusted based on updated feedback channel information received from the destination receiving device.

The wireless node may also process and acknowledge data received from the first master node during the first reserved transmission frame based on the determining, ignore data sent by the second master node during the second reserved transmission frame based on the determining, and process and acknowledge data received from the second master node during the second reserved retransmission frame.

Abstract: Methods and apparatuses are described for versatile phase adjustment schemes comprising multi-layered clock skew correction with variable range and resolution to improve performance for a variety of ADC architectures, including TI-ADCs. Multi-stage phase alignment corrects misalignment in multiple stages at start-up and continuously or periodically during operation to reduce static sources of misalignment caused by design and fabrication and dynamic sources of misalignment caused by operational variations (e.g., voltage, temperature). Multi-path phase alignment corrects misalignment in the data path (e.g., analog path) and the clock path (e.g., digital path, analog path, CMOS path, CML path, or any combination thereof) for distributed alignment. Multi-lane phase alignment corrects misalignment in multiple time-interleaved signal lanes. Multi-resolution phase alignment corrects misalignment at three or more levels of resolution (e.g., coarse, fine and ultra-fine).

Abstract: A two-stage structure for performing non-linear echo cancellation is described in which a first echo canceller is used to attenuate linear echo components of a microphone signal and a second echo canceller is used to attenuate non-linear echo components of the output signal generated by the first echo canceller. One or both of the echo cancellers may be implemented using closed-form solutions, including a closed form solution for a hybrid method in the frequency domain.

Abstract: Aspects of a method and system for compensated time stamping for time-sensitive network communications are provided. In this regard, one or more timestamps generated in an OSI layer above the physical layer may be adjusted based on parameters associated with an amount of time in which data traverses a PHY of the network device. Communications of the network device may be managed based on the adjusted one or more timestamps. The parameters may comprise one or more of: average ingress PHY traversal time, average egress PHY traversal time, variance of ingress PHY traversal time, and variance of egress PHY traversal time. One or more network links coupled to the network device may be characterized based on the one or more adjusted timestamps. The parameters may be stored in one or more registers within a PHY of the network device.

Abstract: A CAM device including a CAM array, multiple match resolution (MMR) circuitry, and a priority encoder allows the addresses of multiple matching locations resulting from a first search operation to be generated without losing the match results generated in second search operation initiated prior to detection of the multiple match condition for the first search operation. When the multiple match condition is detected, the MMR circuitry asserts a stall signal that stalls search operations in the CAM array. The asserted stall signal also causes the match results of the first and second search operations to be stored in separate memory elements so that the addresses of all matching locations for the first search operation can be generated without disturbing the match results of the second search operation.

Abstract: This document discloses a solution where a network element of a cellular communication system detects appearance of a terminal device in the cellular communication system. In connection with registering the terminal device in the cellular communication system, the network element determines that a native frequency band of the terminal device is a sub-band of an operating frequency band of the cellular communication system and, then, allocates to the terminal device frequency resources from the native frequency band of the terminal device.

A validity of a selected control channel may be determined based on a CRC derived from decoding the selected control channel's sub-frame.

Abstract: Embodiments of the present invention provide systems for incorporating bonding processors while avoiding bonding processor buffer overflow by initiating retransmission requests on all data lines whenever corrupted data is encountered on one data line. Initiating these “extra” retransmission requests equalizes retransmissions delays over all transmission lines, preventing the bonding processor from receiving excess data that cannot be reassembled until the retransmission request is processed.

Abstract: An apparatus for improving a gain imbalance between an in-phase and quadrature component recovered by a receiver is provided. The apparatus includes a first transition counter configured to count a number of bit transitions in a first sequence of one-bit values provided by a first sigma-delta modulator based on the in-phase component, and a second transition counter configured to count a number of bit transitions in a second sequence of one-bit values provided by a second sigma-delta modulator based on the quadrature component. The apparatus further includes a gain monitor configured to: (1) determine a first and second power level, proportional to a power of the in-phase and quadrature components respectively, using the number of bit transitions in the first and second sequences, and (2) adjust a gain of one of the in-phase and quadrature components based on a ratio between the first and second power levels.

Abstract: Hierarchical congestion identification and control hardware supports multi-level congestion control at flow, tenant and virtual machine (VM) levels. Hardware implementation expedites response to congestion notifications and frees-up processor bandwidth. A hierarchy of transmit shapers in a transmit ring scheduler isolate rate adjustments for flows, tenants and VMs. The hierarchy of shapers provide a hierarchy of congestion control nodes to control flows and aggregate flows. Hardware quickly associates congested flows with shapers before or after receiving a congestion notification. The associations may be used by any flow control algorithm to selectively rate-control shapers to control flow rates. Shaper associations and configured states, scheduler configuration, congestion states, thresholds and other flow information may be stored and monitored to filter data flows that need attention and to raise alerts at flow, tenant and VM levels.

Abstract: Certain embodiments of the invention may be found in a method and system for antenna and radio front-end topologies for a system-on-a-chip (SOC) device that combines Bluetooth and IEEE 802.11 b/g WLAN technologies. A single chip radio device that supports WLAN and Bluetooth technologies receives a WLAN signal in a WLAN processing circuitry of the radio front-end and in a Bluetooth processing circuitry of the radio front-end. Signals generated by the WLAN processing circuitry and the Bluetooth processing circuitry from the received WLAN signal may be combined in a diversity combiner that utilizes selection diversity gain combining or maximal ratio combining (MRC). When a generated signal is below a threshold value, the signal may be dropped from the combining operation. A single antenna usage model may be utilized with the single chip radio device front-end topology to support WLAN and Bluetooth communications.
