摘要： Techniques for use in designing, adjusting or operating a wireless network so as to provide a desired level of performance for the network. An optimization process is applied to a set of information characterizing the network. The optimization process is implemented as a multi-stage process which includes at least a frequency assignment stage and a post-frequency-assignment optimization stage, wherein the frequency assignment stage and the post-frequency-assignment stage are subject to iteration. For example, after an initial assignment of the frequencies in the frequency assignment stage, the post-frequency-assignment optimization stage may be performed, and based on the result of the optimization, at least one of the frequency assignment stage and the post-frequency-assignment optimization stage may be repeated. An output of the optimization process is utilized to determine one or more operating parameters of the wireless network, such as a base station transmit power or antenna orientation. The optimization process in an illustrative embodiment may be implemented as a three-stage process which includes a pre-frequency-assignment optimization stage, the frequency assignment stage and the post-frequency-assignment optimization stage, with one or more subsets of these stages being implemented in an iterative manner.

摘要： Improved techniques for optimizing performance of a wireless network. In an illustrative embodiment, a derivative-based optimization process is applied to optimize an objective function of a network performance metric with respect to a number of network tuning parameter variables. The optimization may be based on first or higher order derivatives of the objective function with respect to the selected network parameter variables. The objective function may include, e.g., one or more of a maximization of network coverage, a maximization of network capacity, and a minimization of network resources. Additional network parameters which are not variables in optimization process serve as constraints to the optimization process. Advantageously, the invention substantially improves the process of designing, adjusting and optimizing the performance of wireless networks.

摘要： Techniques for determination of network parameters in, e.g., a processor-implemented system for characterizing, adjusting or optimizing the performance of a wireless network. In an illustrative embodiment, values of one or more link parameters of the wireless network are interpolated along edges in a mesh of data points derived at least in part from road location data characterizing an area serviced by the wireless network. A measure of network performance, e.g., a coverage measure based on pilot signal-to-interference ratio, may be generated using the interpolated values. The edges of the mesh have associated therewith a set of edge weights representative of traffic in the wireless network. The edge weights may be adjusted so as to be in agreement with available network traffic data. Interpolating between the data points of the road-based mesh permits the network performance measure to be computed as a smooth, differentiable function of the one or more link parameters, thereby simplifying network characterization, adjustment and optimization.

摘要： Improved techniques for characterizing, adjusting and optimizing the overall performance of a wireless network. In an illustrative embodiment, the overall network performance for a particular network configuration is characterized by a vector with two components, one representing network coverage and another representing network capacity. Network coverage is defined by the likelihood of service under load, including interference, and may be further weighted by traffic density. Network capacity is defined by an amount of traffic with a given spatial distribution that can be served at a given overall target-blocking rate. The overall network performance may be characterized using a two-dimensional capacity/coverage diagram which plots overall network performance vectors, each including a network capacity component and a network coverage component, for various network configurations. The overall network performance may be improved or optimized with respect to a given subset of network parameters by using an algorithm that proposes potential network configurations and evaluates them with respect to their overall network performance.

摘要： Described herein is a method and apparatus for transmission that provides the performance of space time spreading (STS) or orthogonal transmit diversity (OTD) and the backwards compatibility of phase sweep transmit diversity (PSTD) without degrading performance of either STS or PSTD using a symmetric sweep PSTD transmission architecture. In one embodiment, a pair of signals s1 and s2 are split into signals s1(a) and s1(b) and signals s2(a) and s2(b), respectively. Signal s1 comprises a first STS/OTD signal belonging to an STS/OTD pair, and signal s2 comprises a second STS/OTD signal belonging to the STS/OTD pair. Signals s1(b) and s2(b) are phase swept using a pair of phase sweep frequency signals that would cancel out any self induced interference. For example, the pair of phase sweep frequency signals utilize a same phase sweep frequency with one of the phase sweep frequency signals rotating in the opposite direction plus an offset of π relative to the other phase sweep frequency signal. The resultant phase swept signals s1(b) and s2(b) are added to signals s2(a) and s1(a) before being amplified and transmitted.

摘要： Disclosed is a method and apparatus of transmit diversity that is backward compatible and does not degrade performance using a transmission architecture that incorporates a form of phase sweep transmit diversity (PSTD) referred to herein as split shift PSTD.

The phase sweep frequency signals may have a fixed or varying phase shifting rate, may have an identical or different phase shifting rate, may be offset from each other and/or may be phase shifting in the same or opposite direction.
