摘要： Methods and apparatus for including mode information in a wireless transmission frame, which is useful for system acquisition. In particular, a first information bit is provided in a preamble of a transmission frame, where the bit is configured to indicate that a wireless communication system is operating according to either a time division duplex (TDD) mode or a frequency division duplex (FDD) mode. The addition of a single bit minimally affects the resources of the preamble. Additionally, another bit resource already present in the preamble for normally communicating whether FDD transmissions are full duplex or half-duplex transmissions, may be further allocated to indicate partitioning information concerning TDD mode transmissions when the first bit indicates TDD mode, thus affording additional information communicated in the frame without increasing preamble resources.

摘要： A device for generating a pilot signal for use in a wireless repeater where the pilot signal is added to a transmit signal for transmission includes a pilot power control unit configured to set a power level of the pilot signal as a function of a gain of the repeater and a power level of the transmit signal, where the function comprises a linear or non-linear function. In one embodiment, the operation of the repeater may be divided into gain regions and the inserted pilot power is controlled according to the different gain regions of the repeater. When the repeater gain is low, the pilot power may be set greater than the transmit power to ensure there is sufficient signal to use for channel estimation. When the repeater gain is in steady state, the pilot power may be set to be lower than the transmit power to avoid interference.

摘要： A wireless repeater incorporates a gain management block to implement a multi-parameter gain management algorithm. The gain management algorithm receives gain settings from at least a gain control metric for stability and output signal quality and signal headroom values associated with circuitry of the repeater. The gain management block provides secure and robust boot-up of the repeater as well as oscillation detection and prevention. Furthermore, the gain management block implements repeater stability control, output signal-to-noise level control, uplink and downlink gain balance control and compensation for device constraints.

摘要： Methods and apparatus for initial acquisition gain control in a communication system a method for use in a wireless communication system are disclosed. A disclosed methodology includes measuring the power of a signal received by a transceiver a number of times over a prescribed time period, the signal including a number of symbols. A gain of the transceiver is unidirectionally adjusted when a currently measured power is greater than a previously measured power during the prescribed time period until a maximal power level is measured. By adjusting the gain to accommodate a maximal power value, which is the same as the power level of an acquisition pilot symbol, overshoot and distortion by the transceiver are avoided during initial timing and frequency acquisition. Corresponding apparatus are also disclosed.

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： The subject invention selects a starting sub-carrier frequency group for a pilot staggering sequence to facilitate in mitigating the possibility of pilot signal collisions. In one embodiment, a randomized starting sub-carrier frequency group of the pilot is utilized in a first orthogonal frequency division multiplexing (OFDM) symbol of a frame. In another embodiment, a starting pilot sub-carrier frequency group number is determined by utilizing a random number generator such as, for example, a Pseudo-Noise (PN) sequence generator, seeded by a network identification (ID) number. In this manner, the starting sub-carrier frequency group is specific to that particular network. The subject invention also provides a more scalable system through the trading of system bandwidth for coverage.

摘要： The disclosure is directed to a mobile communication device that may receive wireless broadcast signals from a number of different base stations or transmitters. As the location of the device moves relative to the transmitters, one transmitter will likely be identified as the transmitter broadcast the strongest, or highest quality, signal. When that determination is made, the user of the mobile device is presented the opportunity to switch to receiving that transmitters signal. Based on the user's reply, the device may remain with the current transmitter, even though it does not have the strongest signal, or the device may be configured to acquire and start receiving the new transmitter's signal. The measuring of the quality of a transmitter's signal may be based on a composite score that combines a number of individual measurements made over a predetermined period of time.
