Abstract: A mobile station is configured to scan cells in a wireless network. The mobile station includes at least one antenna configured to transmit and receive wireless signals. The mobile station also includes a processor coupled to the at least one antenna, the processor configured to scan for one or more neighboring base station cells in a same frequency band as a serving base station cell using one or more receive beams.

Abstract: Systems and methods for providing dynamic substream definition and handover are provided. In embodiments, a user device includes a multiple radio access technology (RAT) communications modules and a communication controller. Each RAT communication module is further configured to communicate using a different RAT. The user device identifies available networks for communication. Then, the controller determines whether a need to split a communications stream exists (e.g., the user device is engaged in a bandwidth intensive application). If the communications stream is to be split, the controller defines the substreams (either equally or unequally) and assigns a first substream to a communication pathway in a first available network and assigns a second substream to a communication pathway in a second available network. The destination then recombines the substreams. In embodiments, the controller inserts synchronization in the substreams.

Abstract: In an Long Term Evolution (LTE) environment, LTE base stations may collect relevant data from subscribing wireless devices, as well as from nearby LTE base stations and WLAN access points. Based on the collected data, as well as data of the base station itself, the base station may make a determination as to whether to institute offloading of some or all of the subscribing UEs. Rather than independently communicating the offload command to each of the UEs, the base station may issue a broadcast notification that may be decoded by all of the UEs for performing offloading. In order to mitigate a surge of offloading, the base station can include surge prevention parameters in the broadcast message to distribute or reduce offloading.

Abstract: A base station enables a mobile station to employ a random access retransmission scheme in a wireless communication network. The mobile station includes a plurality of antennas configured to communicate with the base station. The mobile station also includes a processing circuitry coupled to the plurality of antennas. The processing circuitry is configured to perform a random access during a random access channel (RACH) burst. The processing circuitry also is configured to at least one of: transmit a random access signal with at least one of an initial transmit power level and an initial transmit beamwidth, and, in response to a random access attempt failure, change at least one of a transmit (Tx) power level and a Tx beamwidth and retransmit the random access signal.

Abstract: In a Long Term Evolution (LTE) environment, the LTE network can coordinate with a subscribing user equipment to manage offloading to a wireless local area network (WLAN) access point or other base station. In doing so, the serving base station on the LTE network can acquire device capabilities of the user equipment and provide configuration details to the user equipment based on those capabilities. These configuration details may cause the user equipment to monitor one or more triggers, and may configure a scan to be later performed by the user equipment. Based on the monitored trigger, the user equipment can then scan the environment according to the scan configuration defined by the base station, and relay scan results to the base station to make a handover determination.

Abstract: Carrier aggregation and dual connectivity allow a user device to communicate with one or more base stations on multiple component carrier frequencies. When it is determined that the user device should handover to a new base station, the user device performs a substantial portion of the needed handover operations with the new base station using only one of the component carrier frequencies. Meanwhile, the user device maintains data communications with the original base station on the remaining component carrier frequencies.

Abstract: A base station transmits energy related information to a mobile station, wherein the energy related information is related to at least one of an energy harvester module and an energy storage module coupled to the base station. The energy related information includes: an energy level and a maximum storage capacity of the energy storage module; an energy harvest rate and energy consumption rate. The base station and the mobile station perform energy trade off, where when the serving base station has an energy level below a threshold, the mobile station uses certain configuration to send information to the serving base station where the configuration can use more resources, such as RF chains, thereby increasing energy consumption of the mobile station while enabling the base station to conserve energy.

Systems and methods for transmitting an offloadable Access Point Name (APN) to a mobile communication device when RAN rules are used. Embodiments of the present disclosure combine the advantages of signaling methods when offloading information to a mobile communication device after a RAN rule has been satisfied such that a base station is able to broadcast a signal that enables all devices camped on an serving cell to offload to the APN.

Abstract: Systems and methods for adaptive access and handover configuration based on historical data are provided. Access and handover decisions are optimized in a multiple radio access technology environment using historical data associated with network performance. Future needs for access and handovers are predicted using historical data associated with the user and historical data associated with network performance. Performance metrics are received periodically or continuously from nodes in one or more networks at a centralized controller. The centralized multi RAT controller correlates these performance metrics and determines predicted handovers for a user device. Preparations for the predicted handovers can then be made prior to the handover event.
