    摘要: Methods, systems, and devices for utilizing flexible bandwidth carriers for small cells are provided. Bandwidth scaling factor(s) for a small cell may be determined. A flexible bandwidth carrier may be generated for the small cell utilizing the bandwidth scaling factor. Some embodiments provide assistance with active hand-in due to more available PN offsets in the flexible bandwidth domain. Some embodiments enhance small cell discovery with high bandwidth scaling factor beacon-like small cells with little more power than that corresponding to the same power spectral density for normal bandwidth small cell. Some embodiments reduce the interference caused by small cell to macrocell users using an adaptive bandwidth scaling factor for small cells based on number of users supported and their traffic demand, to control the extent of overlap the macrocell has with small cell and the interference to macrocell mobiles. Some embodiments utilize self-configuration for small cells utilizing flexible bandwidth channels.

Some embodiments transmit and receive a subset of subframes of voice frames received over flexible bandwidth code channels. In some embodiments, a subset of subframes based on a flexible bandwidth scaling factor of one or more flexible bandwidth code channels is transmitted. The receiver may decode the voice frame based on the received subset of subframes.

    摘要: Methods, systems, and devices for increasing reverse link throughput by coordination of multiple wireless systems using reverse link blanking are provided. Some embodiments involve utilizing the bandwidth of one carrier bandwidth that partially overlaps with the bandwidth of another carrier bandwidth. This overlap may create interference. Different indicators may be utilized to prompt a device, such as a mobile device, to coordinate reverse link transmission blanking on at least one of the carrier bandwidths to increase throughput for the other overlapping carrier bandwidth. For example, a base station may transmit such an indicator to the mobile device to prompt the transmission blanking. Some embodiments also include increasing transmission power for the overlapping carrier bandwidth during the transmission blanking of other carrier bandwidth. Some embodiments utilize flexible carrier bandwidths systems that may utilize portions of spectrum that may not be big enough to fit a normal bandwidth waveform.

    摘要: Apparatus and methods for synchronizing a network element (e.g. access points, femtocells, etc.) to a master network (such as a cellular network) to provide accurate frequency and/or time references for their internal systems. In one embodiment, the network element utilizes a dedicated receiver (or transceiver) to receive timing information from the master network. The implementation of the dedicated receiver is advantageous for cost and simplicity reasons. Furthermore, the timing or frequency information, as received from the master network, is used to correct the network element's internal timing. In addition, the network element's internal timing can operate in open-loop mode, if no master network can be found, thereby allowing for the device to continue providing service to network users. Additionally, a dedicated receiver can also receive information (e.g. location, SID, NID, SSID, etc.) local to the network element, such information may be useful or required for seamless operation within the master network.

    摘要: A pulse density modulator generates output pulses that are optimized as to their even distribution over time. More particularly, the invention represents parallel or serial digital input signals as serial binary output signals, where the binary output pulses are evenly spaced over time to the greatest extent possible. The output signal includes a pattern that repeats during successive “cycles.” The number of pulses in each cycle varies in proportion to the magnitude of the digital input signal. When a digital input signal is provided to an accumulator, the accumulator repeatedly updates a current N-bit sum value by adding the digital input signal thereto. According to this computation, the accumulator either (1) provides a first prescribed signal on a carry output if the current sum cannot be expressed in N bits, or (2) provides a different prescribed signal on the carry output if the current sum can be expressed in N bits. The carry output provides a serial binary output having 2N bits in each cycle. The accumulator may be used as a digital-to-analog converter by routing the carry output to an analog filter. Alternatively, the digital output of the accumulator may be used to provide a trigger signal of repeating, evenly spaced pulses.
