Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04B 700

US Classification:

370277, 370330, 455 76

Abstract:

A transreceiver allows efficient operation in a full or half-duplex TDD or FDD system. The preferred transreceiver includes a common set of filters used for both FDD (Frequency Division Duplex) and TDD (Time Division Duplex) operation in a given range of frequencies thereby reducing circuitry count and implementation costs. Thus, the transreceiver of the present invention can operate in FDD operation or TDD operation.

Appl. No.:

10/016226

Inventors:

Russell A. Morris - Keller TX
Darrell W. Barabash - Grapevine TX

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H03M 1300

US Classification:

714815

Abstract:

A forward error correction (FEC) method is provided that operates in a multiple access format, such as, e. g. , a Time Division Multiple Access (TDMA) format. An FEC transband central station and a plurality of FEC transband remote stations transmit data and corresponding error correction data therebetween during time frames. The time frames are divided into in-band time slots during which the traffic data is transmitted and out-of-band time slots during which the error correction data may be transmitted. The FEC transband remote stations that are assigned to the out-of-band time slots are efficiently and dynamically adjusted during communication.

International Classification:

H04Q 720

US Classification:

455126, 455127, 455 69, 455115, 455343

Abstract:

Apparatus and methods are provided for regulating the power consumption within a wireless communications mobile handset. A base station transmits an RF power output designating signal that indicates a desired level of the RF power output from the mobile handset. The mobile handset receives the RF power output designating signal, where it is used to set the level of the DC power supplied to the mobile handset. In this manner, the minimum amount of power necessary to maintain linear operation of the mobile handset is expended in the mobile handset. The DC power level is set by internally generating a control signal. The level of the control signal is dictated by the desired level of the RF power output as indicated by the received RF power output designating signal. The control signal is then applied to an RF amplifier circuit contained within the mobile handset to set the DC power level. The DC power level can be further varied from the set DC power level in proportion to an envelope of an RF input signal to provide a more power-efficient mobile handset.

International Classification:

H04J 3/16
H04L 1/20

US Classification:

714708, 370468, 714774, 714776

Abstract:

A forward error correction (FEC) method is provided including an FEC dynamic central station and a plurality of FEC dynamic remote stations that transmit bearer data and corresponding error correction data therebetween during a plurality of time frames. The error rate of the communication channel is measured and the amount of error correction data transmitted is accordingly and dynamically adjusted, so that the minimum amount of overhead required to effectively transmit the error correction data is used.

US Classification:

455/139000, 455/296000, 455/278100

Abstract:

A system and method for combining the downlink signals from at least two transceivers to increase the power of the downlink signal. In-phase down link signals from at least two transceivers are combined to produce a downlink output signal having an output power level greater than the power level of any single downlink signal. Detector means, which samples the downlink signals to identify a phase difference is coupled to control a phase controller which adjusts the phase of at least one of the downlink signals to be in step with the phase of the other downlink signal. The phase controller maintains the downlink signals in phase by shifting the phase of at least one of the downlink signals relative to the other.

International Classification:

H04B 138

US Classification:

375222

Abstract:

A radiotelephone system provides a voice channel for carrying voice signals between a mobile unit and a called or calling unit. A first modem in the mobile unit and a second modem connected to a point along the voice channel employ a "blank-and-burst" method of communication to provide a data channel between a first data device connected to the mobile unit and a second data device connected to the second modem. The data channel enables the data devices to communicate with each other seemingly concurrently, and with minimal interference, with the voice signals that are being carried over the voice channel and without requiring modifications to any base station.

International Classification:

H03G 330

US Classification:

330279

Abstract:

An adaptable DC power consumption circuit is provided, wherein the current supplied to an RF amplifier is dynamically varied from a desired level. A feedback control loop is formed between the power terminal and the control terminal of the RF amplifier. A controller influences the feedback control loop to properly set the supply current at the desired minimum level necessary to maintain linear operation of the RF amplifier. The output of the RF amplifier influences the feedback control loop to dynamically vary the supply current from the desired level. In this manner, linear operation of the RF amplifier can be maintained while maximizing the power efficiency of the RF amplifier.
