摘要： There are disclosed systems, devices, and methods for distributing pre-fetch data. A parent node obtains pre-fetch data comprising at least one of: i) data expected to be of interest to a particular user, pre-fetched by the parent node from at least one data source; and (ii) at least one identifier identifying data expected to be of interest to the particular user, for pre-fetching the identified data at a child node. The parent node selects first and second subsets of the pre-fetch data for transmission, respectively, to first and second child nodes, the selecting based on at least a predicted future location of the particular user and a respective geographic location of the first and second child nodes; and transmits the first and second subsets of the pre-fetch data, respectively, to the first and second child nodes.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Spoofed radio control signaling instructions can be used to dynamically adapt management of the radio interface by radio control processors. More specifically, spoofed radio control signaling can be communicated to an accelerator application instantiated on a device-side of a radio control processor. The accelerator application can pre-process the spoofed radio control signaling before forwarding the instructions to a generic radio control processor. In one example, the generic radio control processor has a universal configuration that is capable of being adapted to different telecommunication protocols based on the spoofed radio control signaling. In another example, the spoofed radio control channel signaling is translated into control instructions at the accelerator application, which are forwarded to the generic radio control processor. The control instructions govern processing of downlink data channel transmissions and/or specify parameters of uplink transmissions.
