The invention provides a reference signal generation method, a far-end interference suppression method and communication equipment, and belongs to the technical field of wireless communication, and the reference signal generation method applied to first communication equipment comprises the steps: determining a reference subcarrier interval configuration parameter, a basic sequence and a scrambling sequence of a to-be-generated reference signal; mapping the basic sequence to a physical resource according to the reference subcarrier interval configuration parameter and a scrambling sequence; and generating a time domain continuous signal of the reference signal according to the mapped physical resources. According to the invention, a scrambling sequence (frequency domain OCC) is added, thereference signal multiplexing capability can be remarkably improved on the premise that the reference signal detection processing complexity is not remarkably increased, so that more base stations canparticipate in remote base station interference management, and in addition, the detection complexity of the reference signal can be further reduced by generating the time domain continuous signal ofthe reference signal.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for generating a reference signal, a method for suppressing far-end interference and communication equipment. Background technique [0002] In the TDD (Time Division Duplexing, Time Division Duplex) system (including at least TD-LTE (Time Division Long Term Evolution, Time Division Long Term Evolution) system, and NR (New Radio, new air interface) system), due to the same frequency of uplink and downlink , so if the DL (downlink, downlink) signals of other base stations still have strong receiving power when they reach the UL (uplink, uplink) signal receiving window of the local base station through space propagation, the DL signals of other base stations will be It will cause strong interference to the UL data reception of the local base station, that is, there is strong cross-link interference. Wherein, the interfering base station may be a near-end adj...
