METHOD AND AN APPARATUS FOR MONITORING TIMING OF A TDD SIGNAL TO EXACTLY SET A RATIO OF A DOWNLINK DATA TRANSMISSION SECTION TO AN UPLINK DATA TRANSMISSION SECTION

摘要

PURPOSE: A method and an apparatus for monitoring timing of a TDD signal are provided to exactly set timing of the TDD signal, thereby exactly setting a downlink data transmission section and a uplink data transmission section.;CONSTITUTION: A counter(320) measures size values of a section in which a TDD(Time Division Duplex) signal is the first level and a section in which the TDD signal is the second level. Whenever the level of the TDD signal is changed, a reset signal is generated so that a reset signal generating unit(310) initializes the counter. A control unit(340) monitors timing of the TDD signal by comparing size values of the first/second level sections with one of reference values in which at least one reference value is included at every predetermined period. The reference value group includes the first and second groups which are divided according to bandwidth of a channel.;COPYRIGHT KIPO 2010
