摘要： A first cell (eNodeB) receives (1002) a configuration identifying a plurality of transmission layers in a multi-layer spatial multiplexing scheme (e.g. MIMO) of a MultiMedia Broadcast over a Single Frequency Network (MBSFN). The configuration may identify resource block allocations to transmission layers, seed values for pattern generation, and timing information used to allocate resource blocks to transmission layers.

摘要： A wireless repeater in a multi-repeater environment operates to detect the presence of neighboring repeaters and to maintain repeater stability in the presence of a neighboring repeater. In some embodiments, the repeater transmits a known signal sequence to discover the presence of a neighboring repeater. When a neighboring repeater is detected, the repeater may apply mitigation measures to maintain operational stability at the repeater.

摘要： A wireless repeater includes a gain control metric computation block to compute a gain control metric for use in controlling the variable gain of the repeater. The gain control metric is computed by downsampling the gain control input signal to the gain control metric computation block and also downsampling the computed correlation and normalization terms. The gain control metric may be further enhanced by filtering the computed metric values using linear or non-linear filtering.

摘要： Methods and apparatus for constructing a pilot symbol for a communication frame transmitted in a wireless communication system, such as an OFDM system, are disclosed. In particular, the methods and apparatus generate at least one pseudo-random noise sequence having at least a predetermined length, where the at least one pseudo-random noise sequence represents a system configuration of a wireless system. A time domain symbol sequence is modulated with the at least one pseudo-random noise sequence to create a timing acquisition pilot symbol. The modulated acquisition pilot symbol is further masked to a prescribed frequency profile and placed in a frame for wireless transmission. Accordingly, different system configurations can be communicated from a transmitter to a receiver with the acquisition pilot symbol modulated with correspondingly different pseudo-random noise sequences, while affording low complexity required to process the acquisition pilot symbol and a minimum peak to average power ratio when using QPSK modulation.

摘要： A wireless repeater introduces a low level noise to the signal path of the repeater where the introduced noise is used to facilitate channel estimation. The introduced low power level noise may be added to the receive signal or to the transmit signal. The low power noise signal ensures that the repeater always has a reference signal for performing channel estimation, even when the repeater is not receiving any incoming signal traffic. In one embodiment, a low noise signal is inserted to the transmit circuit of the repeater. In another embodiment, the repeater is configured to increase the noise figure of the receive circuit where the detected noise figure acts as a receive signal.

摘要： In an embodiment, a first repeater configures a beacon signal that identifies the first repeater to one or more other repeaters. The first repeater transmits the configured beacon signal at a given transmission power level to the one or more other repeaters. The transmitted beacon signal is received at least by a second repeater. The second repeater reduces interference associated with other transmissions from the first repeater, such as retransmissions of donor signals, based on the received beacon signal.

摘要： A method for controlling gain in a wireless repeater includes computing a gain control metric indicative of a loop gain of the repeater and detecting changes in a signal power of a gain control input signal where the gain control input signal is taken from any point in the feedback loop of the repeater. When a large power swing in the gain control input signal is detected, the method operates to discard at least a portion of each gain control metric measurement for a first duration before continuing with computing the gain control metric. In another embodiment, the method may include discarding samples of the gain control input signal used in computing the gain control metric for a first duration when a large power swing in the gain control input signal is detected.

摘要： Apparatus and methods for estimating the frequency of a sleep or slow clock using a fast clock, such as a temperature compensated crystal oscillator. The disclosed apparatus include an estimator having a first counter that receives sleep clock synchronized pulses issuing each cycle of the sleep clock period, yet are synchronized to a fast clock. The slow clock synchronized pulses are counted up to a predetermined number; whereupon a full count signal is issued. A second counter receives the full count signal and increments each time the full count signal is received. A third counter counts fast clock cycles until the full count signal occurs. Based on the number of counts of the slow and fast clock cycles, the frequency of the slow clock may be determined using only the domain of the fast clock for performing the measurement thereby tying accuracy of the measurement to the accuracy of the fast clock. The disclosed apparatus also include an integrated circuit and a transceiver employing the disclosed estimator. Corresponding methods are also disclosed.
