    摘要： A method for estimating a feedback channel for a wireless repeater using frequency domain channel estimation estimates an error correction term using a most recent channel estimate and cancels the error correction term from a current block of the receive signal. Then, the feedback channel is estimated using frequency domain channel estimation and using a current block of the pilot signal and the corrected block of the receive signal. A channel estimate error term may also be estimated and subtracted directly from the channel estimate.

    摘要： Systems and methodologies are described that enable serving cell selection in a wireless network with a multiple antenna repeater operable to support MIMO communications. In one example, a repeater using orthogonal frequency division multiplexing on the downlink can be equipped to receive, by one or more receive antennas, one or more signals using one or more radio frequency (RF) isolation schemes. The repeater can further be equipped to amplify and delay the one or more signals using one or more combination schemes. Moreover, the repeater can be equipped to transmit, by one or more transmit antennas, the amplified and delayed one or more signals, wherein at least one of the one or more receive antennas or the one or more transmit antennas includes two or more antennas.

    摘要： Techniques for transmitting data using single-carrier frequency division multiple access (SC-FDMA) multiplexing schemes are described. In one aspect, data is sent on sets of adjacent subbands that are offset from one another to achieve frequency diversity. A terminal may be assigned a set of N adjacent subbands that is offset by less than N (e.g., N/2) subbands from another set of N adjacent subbands assigned to another terminal and would then observe interference on only subbands that overlap. In another aspect, a multi-carrier transmission symbol is generated with multi-carrier SC-FDMA. Multiple waveforms carrying modulation symbols in the time domain on multiple sets of subbands are generated. The multiple waveforms are pre-processed (e.g., cyclically delayed by different amounts) to obtain pre-processed waveforms, which are combined (e.g., added) to obtain a composite waveform. A cyclic prefix is appended to the composite waveform to generate the multi-carrier transmission symbol.

    摘要： A method for monitoring feedback loop stability in a wireless repeater includes measuring a gain control metric in the feedback loop of the repeater periodically for a given time period where the gain control metric is indicative of a loop gain of the feedback loop of the repeater; and monitoring the magnitude of the gain control metric to determine the stability of the feedback loop of the repeater. In operation, a large magnitude of the gain control metric indicates instability in the feedback loop of the repeater.

    摘要： A method of controlling gains within a repeater may include determining a power control set point value which controls a transmit power of a mobile station (MS), and receiving a downlink signal from a base station transceiver system (BTS). The method may further include measuring a power of the received downlink signal, and computing a power level of a signal expected at the uplink of the repeater, wherein the computing is based on the measured downlink power and the power control set point value. Finally, the method may further include adjusting a gain of at least one amplifier based on the computed power level. An apparatus for controlling gains in a repeater may include a baseband processor for performing the above method.
