Abstract: 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.

Abstract: 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.

Abstract: A user equipment (UE) may compute uplink power control levels as a function of a downlink signal to noise ratio (SNIR). For example, the UE may determine an uplink transmit power level by summing a full power control (FPC) transmit power level, a product of a first adjustment factor (β) and the downlink SNIR, and a negative of a second adjustment factor (Δ2) when the product of the first adjustment factor (β) and the downlink SNIR is greater than or equal to the second adjustment factor (Δ2). A UE may also compute an uplink power control level as a function of target and/or current interference levels associated with neighboring base stations. A UE may also iteratively reduce a transmit power level until an interference level experienced by a neighboring base station has fallen below a threshold.

Abstract: Inter-cell interference can be reduced by re-assigning uplink scheduling responsibilities for a user equipment (UE) from a controller associated with a serving access point (AP) to a controller associated with a neighboring AP, as the controller associated with the neighboring AP may have better access to channel information corresponding to interference experienced by the neighboring AP as a result of uplink transmissions from the UE. After the re-assignment, the controller associated with the neighboring AP may independently schedule an uplink transmission parameter (e.g., a transmit power level, a modulation coding scheme level and/or a precoder) of the UE in a manner that mitigates inter-cell-interference in the neighboring cell.
