23 Mar 2010TL;DR: In this article, the authors propose to temporarily suspend broadcast of data in an active content flow when insufficient data is available for efficient use of the broadcast bandwidth, while signaling receiver devices so they may deactivate receiver circuits to conserve power while data broadcasts are suspended.
Abstract: Embodiments enable multimedia broadcast systems to temporarily suspend broadcast of data in an active content flow when insufficient data is available for efficient use of the broadcast bandwidth, while signaling receiver devices so they may deactivate receiver circuits to conserve power while data broadcasts are suspended. Flow content received in the broadcaster during the temporary suspension of data broadcasts may be stored in flow buffers for broadcast at the end of the temporary suspension. An indication of the duration of suspended data broadcasts may be included in the overhead information symbols (OIS) within the broadcast signal. Receiver devices receiving the indication of suspended data broadcasts may deactivate their receiver circuits for the indicated duration. The broadcast suspensions may be coordinated across multiple content flows so that receiver devices can periodically wake up at induced sleep intervals to monitor any data flow of the broadcast system.

12 Apr 2011TL;DR: In this article, a first waveform that includes one or more segments of a payload that originated from an origin station with a sequence of multiple segments was transmitted over a shared medium by the origin station and by each of one or multiple repeater stations.
Abstract: Communicating between stations over a shared medium comprises: receiving, at a destination station, a first waveform that includes one or more segments of a payload that originated from an origin station with a sequence of multiple segments, the one or more segments included in the first waveform having been transmitted over the shared medium by the origin station and by each of one or more repeater stations, and the first waveform indicating which of the sequence of multiple segments were not correctly decoded by at least one of the repeater stations; generating, based on the first waveform, acknowledgement information that specifies which of the sequence of multiple segments have been correctly decoded by the destination station; and transmitting a second waveform from the destination station over the shared medium, the second waveform including the acknowledgement information.

03 Apr 2006TL;DR: In this paper, methods and apparatuses for providing flexible channel information feedback are disclosed for providing flexibility in channel information analysis, and a reporting mode is determined to determine the reporting types to be utilized.
Abstract: Methods and apparatuses are disclosed for providing flexible channel information feedback. In some cases this may be according to reporting types assigned by one or more sectors, with different reporting types for each sector. In other cases, a reporting mode is determined to determine the reporting types to be utilized.

05 May 1995TL;DR: An integrated search processor used in a modem for a spread spectrum communications system buffers receives samples and utilizes a time sliced transform processor operating on successive offsets from the buffer as discussed by the authors, which autonomously steps through a search as configured by a microprocessor specified search parameter set, which can include the group of antennas to search over, the starting offset and width of the search window to search, and the number of Walsh symbols to accumulate results at each offset.
Abstract: An integrated search processor used in a modem for a spread spectrum communications system buffers receive samples and utilizes a time sliced transform processor operating on successive offsets from the buffer The search processor autonomously steps through a search as configured by a microprocessor specified search parameter set, which can include the group of antennas to search over, the starting offset and width of the search window to search over, and the number of Walsh symbols to accumulate results at each offset The search processor calculates the correlation energy at each offset, and presents a summary report of the best paths found in the search to use for demodulation element reassignment The search is done in a linear fashion independent of the probability that a signal being searched for was transmitted at any given time

23 May 2004TL;DR: A novel bias circuit is proposed to generate the gate voltage for zero 3rd-order nonlinearity of the FET transconductance and measured data show that a peak in IIP/sub 3/ occurs at a gate voltage slightly different from the one predicted by the dc theory.
Abstract: A FET linearization technique based on optimum gate biasing is investigated at RF. A novel bias circuit is proposed to generate the gate voltage for zero 3rd-order nonlinearity of the FET transconductance. The measured data show that a peak in IIP/sub 3/ occurs at a gate voltage slightly different from the one predicted by the dc theory. The origins of this offset are explained based on a Volterra series analysis and confirmed experimentally. The technique was used in a 0.25 /spl mu/m CMOS cellular-band CDMA LNA. At the optimum bias, the amplifier achieved a NF of 1.8 dB, an IIP/sub 3/ of +10.5 dBm, and a power gain of 14.6 dB with a current consumption of only 2 mA from 2.7 V supply.
