摘要： Methods, systems, and devices are described for making scaling adjustments with respect to a fractional subsystem in a wireless communications system. To handle the effects of scaling associated with fractional bandwidth systems, different adjustments may be made to maintain certain quality of service (QoS) requirements, for example. Scaling adjustments may include identifying a scaling factor for the fractional subsystem and a parameter and/or a timer associated with the fractional subsystem. An adjustment associated with the parameter and/or timer may be determined based on the scaling factor. The adjustment may be applied with respect to the parameter and/or timer for at least a portion of the fractional subsystem or another portion of the wireless communications system.

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： Methods, systems, and devices are provided for dynamically adapting the bandwidth of flexible bandwidth carriers. Adapting the bandwidth of a flexible bandwidth carrier may be achieved through changing the scale factor of the flexible bandwidth signal. Information such as traffic patterns, interference measurements, etc., may be utilized to determine the adapted scaling factors. In macrocellular deployments, for example, dynamically adjusting the bandwidth of a flexible bandwidth system may be utilized in order to increase network capacity, mitigate interference caused to other carriers, avoid adjacent carrier interference, and/or save energy on the network. Traffic pattern and other information may also be utilized to dynamically adjust uplink and downlink bandwidths of a flexible bandwidth carrier, either jointly or independently.

摘要： Methods, systems, and devices are provided for coordinating forward link blanking and/or power boosting in wireless communications systems. Some embodiments include two or more bandwidth systems. The bandwidth of one bandwidth system may overlap with the bandwidth of another bandwidth system. This overlap may create interference. Coordinating forward link blanking and/or power boosting may aid in reducing the impact of this interference. Some embodiments utilize flexible bandwidth and/or normal bandwidth systems. Flexible bandwidth systems may utilize portions of spectrum that may not be big enough to fit a normal waveform, though some embodiments may utilize flexible waveforms that utilize more bandwidth than a normal waveform.

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： 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.

摘要： Methods, systems, and devices for separating signaling data and traffic data onto separate carriers for wireless communications systems are provided. Some embodiments utilize flexible bandwidth that may utilize portions of spectrum that may not be big enough to fit a normal waveform through utilizing flexible waveforms. Flexible bandwidth systems may lead to reduced data rate on the signaling or other channels. Separating the signaling and the data traffic into different flexible bandwidth carriers so that assigned resources can be customized to different traffic patterns may address this issue. In some embodiments, the signaling data is received and/or transmitted over a first carrier separate from any other traffic data. For example, the signaling data may be received and/or transmitted over the first band carrier without any other traffic data. The traffic data and/or network data associated with the signaling data may be received and/or transmitted over a separate, second carrier.

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.
