| 20110211560 | MOBILITY CONTROL METHOD MITIGATING INTER CELL INTERFERENCE AND BASE STATIONS WHICH ADOPT THE METHOD - Interference applied to neighbor cells during terminal handovers can be reduced in wireless communication systems containing base stations having different cell sizes. A serving cell makes handover judgment criteria easier based on pre-acquired cell size information on its own cell and cell size information of neighbor cells in order to facilitate terminal handovers from a base station with a large cell size to a base station with a small cell size. The serving cell finds evaluation function values based on the propagation state (e.g. reference signal received power) between the terminal and target cell, and the interference and load information exchanged between the base stations, and selects the terminal for handover by comparing the evaluation function value with the handover criteria value. The system selects a target cell having a good effect in lowering interference such as a cell with large reference signal received power acquired from a terminal, to serve as the handover destination. | 2011-09-01 |
| 20110211561 | SUPERPOSITION CODING IN A WIRELESS COMMUNICATION SYSTEM - The present patent application comprises a method and apparatus to compile a superposition coded packet by compiling user candidates for superposition coding, ranking the user candidates based on a result of an evaluation function, selecting a deserving user candidate from among the user candidates, and compiling a superposition coded packet by adding other user data packets to a packet of the deserving user data packet, wherein the data packets for the user candidates may conform to a plurality of different formats and wireless communication standards. | 2011-09-01 |
| 20110211562 | METHODS AND APPARATUSES FOR BEACON TRANSMISSION - Various methods and apparatuses for beacon transmission in an ad-hoc peer-to-peer network are disclosed. In one aspect, an apparatus for communication is disclosed, the apparatus comprising a processing system configured to sense a channel during a first period comprising at least a first portion of a beacon transmission period and select, based on the sensing, a second period comprising at least a second portion of a beacon transmission period; and a transmitter configured to transmit one or more beacons during the second period. | 2011-09-01 |
