Title:
METHOD AND SYSTEM FOR ACQUIRING FREQUENCY RESPONSE DIFFERENCE OF RADIO REMOTE UNIT (RRU) CHANNEL, AND BASE STATION EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2017/106999
Kind Code:
A1
Abstract:
A method, device and system for acquiring the frequency response difference of radio remote unit (RRU) channels, in the method: a plurality of RRU channel groups are divided between a building baseband unit (BBU) and a radio remote unit (RRU), and all RRU channels in each RRU channel group are interconnected by means of a same bridge; the method comprising: respectively acquiring, for a first RRU channel and a second RRU channel that are interconnected in any one of the RRU channel groups, frequency response differences between the first RRU channel and an independent RRU channel, and between the second RRU channel and the independent RRU channel, the independent RRU channel being not in the any one of the RRU channel groups; and acquiring the frequency response difference between the first RRU channel and the second RRU channel on the basis of the frequency response differences between the first RRU channel and the independent RRU channel and between the second RRU channel and the independent RRU channel. The embodiments of the present invention are capable of accurately acquiring the frequency response difference between interconnected RRU channels.
