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: 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: Embodiments are provided for assessing radio resource requirements using virtual bin virtualization. An embodiment method includes receiving a service request from a user equipment (UE) in a geographical bin. Resource requirements are then obtained, from a lookup table (LUT), for a serving radio node and neighbor radio nodes associated with the geographic bin of the UE. The LUT comprises a plurality of entries that map combinations of path losses of wireless links for the serving radio node and neighbor radio nodes to corresponding combinations of resource requirements. The entries of the path losses further include one or more service specific and network node parameters for the serving radio nodes and neighbor radio nodes, which are also mapped to the resource requirements. The obtained resource requirements are then assessed, including deciding whether to serve the UE according to the resource requirements and to resource availability.

Abstract: Embodiments are provided for uplink measurement based mechanism and control using user equipment (UE) centric sounding signals. The mechanism provides an alternative to DL-measurement dominated system control. Based on UL-measurements at TPs, the network obtains knowledge of users' channel and timing information, traffic, and interference, and is thus able to perform better control, including TP and UE clustering and optimization, and power control and link adaptation. In an embodiment method, a TP receives one-to-one mapping information indicating a plurality of UE IDs and a plurality of sounding channels assigned to the corresponding UE IDs. When the TP detects a sounding reference signal (SRS) from a UE, the TP is able to identify the UE using the detected SRS and the one-to-one mapping information. The TP then obtains measurement information for the identified UE, enabling better control and communications for uplink and downlink transmissions between multiple TPs and the UE.
