20110228747 | Methods and Systems for Uplink Network Entry and Bandwidth Requests - Methods and systems of a mobile station transmitting information to a base station are disclosed. The mobile station may transmit information with improved uplink coverage, and bandwidth requests may be more efficient. Additionally, the mobile station may transmit information over multiple uplink frames using hybrid ARQ. | 09-22-2011 |
20130130751 | WIRELESS COMMUNICATION DEVICE HAVING REDUCED POWER CONSUMPTION - A wireless communication device is disclosed that is capable of reduced power consumption. Uplink and downlink sub-frames in a WiMAX, 802.16m or LTE environment often include several vacant symbols during which power-hungry hardware and software components need not operate at full power. By analyzing a physical layer beacon and control information of a received signal, the specific locations of data bursts can be determined, as well as periods of needed operation of a receiver module to effectively decode those data bursts. The receiver module can otherwise be controlled to operate in a LOW power state during remaining periods of vacant time, thereby conserving power consumption and extending battery life. | 05-23-2013 |
20130163441 | DECOUPLED DOWNLINK AND UPLINK - The present disclosure provides systems and methods for decoupling downlinks and uplinks between user equipment (UE) and base stations. Briefly described, in architecture, one embodiment of the system comprises UE (e.g., cellular telephones, mobile devices, etc.) for independently establishing an uplink (UL) and a downlink (DL). One embodiment of the method comprises the steps of establishing a DL to an optimal DL base station (BS), and establishing an UL to an optimal UL BS. | 06-27-2013 |
20130343252 | Power Saving for Mobile Terminals - Embodiments provide power saving schemes for a user equipments (UE) in low power supply state. The power saving schemes include network-assisted power saving schemes and UE-triggered power saving schemes. Network-assisted power saving schemes require network awareness of the low power supply state of the UR Thus, embodiments provide the UE the ability to communicate its power supply state to the network. UE-triggered power saving schemes may or may not require network awareness of the UE s power supply state andd/or of the execution of the HE-triggered power saving scheme at the UE. | 12-26-2013 |
20140040694 | TRANSMISSION TIME INTERVAL (TTI) BUNDLING OPERATION WITHIN COMMUNICATION SYSTEMS - TTI bundling is included for Msg | 02-06-2014 |
20140211757 | Wireless Communication System Utilizing Staggered Device Handovers - 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. | 07-31-2014 |
20140355566 | Cross Radio Access Technology Access with Handoff and Interference Management Using Communication Performance Data - 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. | 12-04-2014 |
20150223089 | TIME OFFSET ACQUISITION FOR DUAL CONNECTIVITY - Devices and methods for determining timing offsets between wireless devices are provided. One method includes transmitting, from a first device, a request for timing data to first user equipment and receiving a response. The timing data is indicative of a frame timing associated with a reference time for both the first device and a second device. The method further includes determining a timing offset between the frame timing for the first device and a frame timing for the second device based on the timing data. Another method includes receiving a reference time from a timing reference device, applying a timestamp to frame timing data for the first device, receiving frame timing data from the second device time-stamped based on the reference time, and comparing the timing data to determine a time offset between the devices. | 08-06-2015 |
