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： Methods and apparatus for decoding frame packet data in a communication system to reduce latency for decoding particular types of broadcast signals in a frame. In particular, decoding of a communication signal includes demodulating at least a particular type of encoded broadcast channel modulation symbol received in a frame before completion of reception of a certain number of frames each including the particular type of encoded broadcast channel modulation symbol are received. After demodulation, the demodulated encoded broadcast channel modulation symbol is then decoded by a decoder. A determination is then made whether decoding of the first broadcast channel modulation symbol is successful. If decoding is successful, decoding of subsequent broadcast channel modulation symbols is terminated. Otherwise, decoding is incrementally or iteratively continued (i.e., a next received frame and so on) until decoding is determined to be successful.

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 multipath signal searcher (204) used in CDMA wireless communication systems is provided. Search paths (214) of the multipath signal searcher are grouped together and assigned by an offset assignment/timing block (210) to search a time offset within a search window. The search paths may be operated In serial or parallel operation mode. In either mode, the search paths are individually assigned to search over one of a group of time offsets that are distributed across the search window evenly. In parallel mode, the search paths are not only grouped to search only a given set of time offsets within the search window, but different groups of search paths are offset to commence searching at different times then other groups of search paths to more quickly update a finger manager and more quickly retrieve the mobile communication signal.
