Abstract: A hierarchical link scheduling system and method is provided. A central controller gathers network information, including global parameters and long term demands, and determines an initial schedule for link activation based on these variables.

The scheduler activates the links according to the modified schedule. Accordingly, the scheduler can be responsible for modifying the initial schedule provided by central controller with localized or short term requests or demands, and providing the necessary parameters to enable link activation between nodes according to the modified schedule.

Abstract: Embodiments are provided for a location-based network discovery and connection establishment, which take advantage of location/positioning technology of user equipment (UE) and resolve issues above of the blind search approaches. The location-based network discovery and connection establishment schemes use UE location information and a network access MAP to speed up network discovery, and remove the need for continuous search and measurement by the UE. The schemes also reduce the search space. A wireless network access map (MAP) is provided to the UE. The UE uses the MAP information with UE current location information to reduce the search space and speed up network discovery and radio connection establishment with the network. Network operators can use this network access MAP to control the network access and manage the network load distribution. The network access MAP can be customized for each UE.

Abstract: It is possible to achieve fast high-frequency link discovery by communicating location parameters identifying a spatial location of a mobile device over a low-frequency interface to a low-frequency access point (AP). The location parameters are then used to identify antenna configuration parameters (e.g., precoders, etc.) for communicating discovery signals between the mobile device and a high-frequency access point. In one embodiment, the low-frequency AP relays the location parameters to the high-frequency AP, which uses the spatial location of the mobile device to perform link discovery. In another embodiment, the low-frequency AP communicates high-frequency antenna configuration parameters to the mobile device over the low-frequency interface.

Abstract: Dynamic point selection (DPS) can be implemented using access points having partial or no DPS synchronization. Specifically, a mobile device may broadcast a bounce back message to access points participating in DPS transmissions to signal that a data segment has been successfully received and/or decoded by the mobile device. The bounce back message may cause the access points to drop remaining packets corresponding to the data segment from their buffers without sending those remaining packets over their respective radio interfaces. The bounce back message may be broadcast over any wireless signaling channel, such as via radio link control (RLC) signaling. Moreover, different priorities may be assigned to encoded packets intended for DPS transmission based on whether the encoded packets are communicated over a primary or secondary backhaul path.

Abstract: 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.

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.
