摘要:
Increased resource utilization efficiency can be improved by modeling path costs during admission and path-selection. Specifically, path costs for candidate paths are modeled based on load characteristics (e.g., current load, load variation, etc.) of links in the candidate paths. Path costs can represent any quantifiable cost or liability associated with transporting a service flow over the corresponding path. For example, path costs can correspond to a probability that at least one link in the path will experience an outage when transporting the service flow, a price charged by a network operator (NTO) for transporting the traffic flow over the candidate path, or a total network cost for transporting the flow over a candidate path. The candidate path having the lowest path cost is selected to transport a service flow.

Interference costs on virtual radio interfaces can be modeled as a function of loading in a wireless network to estimate changes in spectral efficiency and/or resource availability that would result from a provisioning decision. In one example, this modeling is achieved through cost functions that are developed from historical and/or simulated resource cost data corresponding to the wireless network. The cost data may include interference data, spectral efficiency data, and/or loading data for various links over a common period of time (e.g., a month, a year, etc.), and may be analyzed and/or consolidated to obtain correlations between interference costs and loading on the various links in the network. As an example, a cost function may specify an interference cost on one virtual link as a function of loading on one or more neighboring virtual links.

Predicting mobile station migration between geographical locations of a wireless network can be achieved using a migration probability database. The database can be generated based on statistical information relating to the wireless network, such as historical migration patterns and associated mobility information (e.g., velocities, bin location, etc.). The migration probability database consolidates the statistical information into mobility prediction functions for estimating migration probabilities/trajectories based on dynamically reported mobility parameters. By example, mobility prediction functions can compute a likelihood that a mobile station will migrate between geographic regions based on a velocity of the mobile station. Accurate mobility prediction may improve resource provisioning efficiency during admission control and path selection, and can also be used to dynamically adjust handover margins.

Various devices and methods are provided that use signaling to support advanced wireless receivers. For example, a method includes receiving an input signal at a user equipment. The input signal includes a desired signal and an interfering signal, where the desired signal defines symbols using constellations. The method also includes obtaining information identifying a wireless channel used by the interfering signal and a modulation type used to modulate data in the interfering signal. The method further includes recovering the symbols from the desired signal using the information.
