A user equipment (UE) is configured to request connection to a selected one of a plurality of available network slices of a network system. The UE implements a permission control framework that allows individual applications to request connection to the selected network slice, but establishes the connection only when the framework determines, based on any of a variety of permission criteria, that the application is permitted to access the requested network slice. The UE also supports user selection of the network slice via a graphical user interface that presents a selectable list of available network slices.

Permission-based network slice selection

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.

Cross radio access technology access with handoff and interference management using communication performance data

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. The one or more receive beams used for scanning are different than receive beams used for data communication with the serving base station cell.

Methods and apparatus for cell scanning in system with large number of antennas

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.

Systems and methods for splitting and recombining communications in multi-network environments

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.

Wireless communication system utilizing broadcast-based blind offloading

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.

Apparatus and method for random access with multiple antennas in a wireless network

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.

Wireless communication system utilizing enhanced air-interface

A mobile station performs a method for random access in a wireless network. The method includes receiving, from a base station, information regarding a configuration of at least one receive beam of the base station to receive a random access signal. The method also includes configuring at least one transmit beam for a transmission of the random access signal based on the configuration information from the base station. The method further includes transmitting the random access signal to the base station on the at least one transmit beam.

Methods and apparatus for flexible beam communications in random access in system with large number of antennas

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.

Wireless communication system utilizing staggered device handovers

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.
