In certain embodiments, transmission can be between a base station and two or more user terminals, wherein the base station and user terminals are each equipped with more than one antenna. | 2011-12-29 |
20110317576 | METHOD FOR AUTOMATICALLY CONFIGURING A NEIGHBOR CELL LIST FOR A BASE STATION IN A CELLULAR WIRELESS NETWORK - A method for automatically configuring a neighbor cell list, NCL, for a base station in a cellular wireless network, comprises receiving measurement reports for neighbor cells from a plurality of mobile stations. The reports are grouped by the neighbor cell with which each is associated. Neighbor cells are selected for inclusion in the NCL depending on the number of reports in their respective group. | 2011-12-29 |
20110317577 | COMMUNICATION SYSTEM AND MOBILE STATION APPARATUS - Provided are a communication system, a base station apparatus, a mobile station apparatus, and a communication method which can effectively manage measurement information held by a base station apparatus and a mobile station apparatus in a system comprising a plurality of component carriers. The mobile station apparatus is used in a mobile communication system configured by a base station apparatus and a mobile station apparatus. For a plurality of cells with the cell having different frequency, a reference cell with respect to an object to be measured is defined as a measurement reference cell when executing a measurement. The mobile station apparatus specifies one or more of the measurement reference cell for the object to be measured and executes a measurement of the object to be measured for the specified one or more of the measurement reference cell. | 2011-12-29 |
20110317578 | SYSTEM AND METHOD FOR TRANSMITTING SERVICE DATA FROM A SERVER TO A TERMINAL VIA A BASE STATION - A base station transmits service data to a terminal at a first transmission rate. A server transmits the service data to the base station at a second transmission rate required for transmitting the service data. When the second transmission rate exceeds the first transmission rate, the server determines a part of the service data by thinning out the service data so that the part is able to be transmitted to the terminal at the first transmission rate. The server provides the determined part with marking information, and transmits the service data provided with the marking information to the base station at the second transmission rate. The base station extracts the part from the received service data based on the marking information provided for the part, and transmits the extracted part of the service data to the terminal at the first transmission rate. | 2011-12-29 |
20110317579 | SERVER FOR UPDATING LOCATION BEACON DATABASE - A location beacon database and server, method of building location beacon database, and location based service using same. Wi-Fi access points are located in a target geographical area to build a reference database of locations of Wi-Fi access points. At least one vehicle is deployed including at least one scanning device having a GPS device and a Wi-Fi radio device and including a Wi-Fi antenna system. The target area is traversed in a programmatic route to reduce arterial bias. The programmatic route includes substantially all drivable streets in the target geographical area and solves an Eulerian cycle problem of a graph represented by said drivable streets. While traversing the target area, Wi-Fi identity information and GPS location information is detected. The location information is used to reverse triangulate the position of the detected Wi-Fi access point; and the position of the detected access point is recorded in a reference database. | 2011-12-29 |
20110317580 | SYSTEM AND METHOD FOR MONITORING AND OPTIMIZING NETWORK PERFORMANCE TO A WIRELESS DEVICE - In one embodiment, a method for monitoring and optimizing network performance to a wireless device that includes determining network performance information of a wireless router and communicating data packets containing the network performance information between said wireless router and a packet network switch. The data packets are communicated from said packet network switch to a network management device. The network management device is configured to instruct the said packet network switch to adjust at least one of encoding/decoding rate and power amount to optimize said network performance to said wireless device. | 2011-12-29 |
20110317581 | RADIO RECEPTION APPARATUS, RADIO TRANSMISSION APPARATUS, AND RADIO COMMUNICATION METHOD - In a case where a second reference signal for a second communication system is transmitted in addition to a first reference signal for a first communication system, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS for LTE-A, last half symbols in a time direction of a resource unit RB/Sub-frame defined in a frequency-time domain are used, and the CSI-RS is allocated in a position up to the last two symbols or in the last symbol, or the like, of a particular RB/Sub-frame and transmitted when a reference signal | 2011-12-29 |
