Description
Technical field
The present invention relates to wireless communication technology field, particularly a kind of method, system and equipment that carries out interference coordination.
Background technology
The basic duplex mode adopting for cellular system, TDD (Time division duplex, time division duplex) pattern refers to that uplink downlink is used same working band, on the different time intervals, carry out the transmission of uplink and downlink signals, between up-downgoing, there is protection interval (Guard Period, GP); FDD (Frequencydivision duplex; Frequency Division Duplexing (FDD)) pattern refers to that uplink downlink is used different working bands; can when same, be engraved in the transmission of carrying out uplink and downlink signals on different frequency carriers, between up-downgoing, have protection bandwidth (Guard Band, GB).
