METHOD AND APPARATUS FOR INITIALLY RANGING HETEROGENEOUS NETWORKS IN A WIRELESS CONNECTION SYSTEM CAPABLE OF IMPROVING THE TRANSMISSION EFFICIENCY OF THE WIRELESS CONNECTION SYSTEM

摘要

PURPOSE: A method and apparatus for initially ranging heterogeneous networks in a wireless connection system are provided to selectively use resources including a good channel state using area extension technology.;CONSTITUTION: A terminal selects a serving cell by considering of the weight value of a base station using a range expansion method(801). The terminal receives a threshold value information and a ranging code classification information of the serving cell(803). When the channel quality of the serving cell is under the threshold value, the terminal selects one of the deteriorated prediction ranging codes using the ranging code classification information(805). The terminal executes an initial ranging method using the selected deteriorated prediction ranging code(809).;COPYRIGHT KIPO 2013;[Reference numerals] (801) A serving cell is selected by considering area expansion; (803) Synchronization acquisition of a serving cell, ranging code classification information, and threshold value information reception; (805) Is the channel quality of a serving cell is under a threshold value?; (807) Performance of normal initial ranging process and communication; (809) Initial ranging is tried using a degradation predicted ranging code; (811) Ranging response reception including low channel quality recognition informaiton; (813) Resource information reception balanced with interference; (815) Indirectly balanced resource section?; (817) Signal reception and data calculation stop; (819) Signal reception and data decoding operation performance; (AA) Start; (BB,DD) No; (CC,EE) Yes; (FF,GG) End
