Problems solved by technology

In this way, the fixed reference signal configuration in LTE can no longer meet the requirements of the new system
For example, the full-duplex method will bring uplink and downlink interference between cells and within the cell. For example, the fixed reference signal mapping method and the determination of the reference signal base sequence in LTE can no longer meet the needs of future 5G communication systems.

Abstract

The present application provides a method and device for configuring a reference signal, the method comprising: determining the configuration information of the reference signal according to a first parameter, the first parameter including transmission characteristics, subcarrier spacing, and a working frequency band of the subcarrier spacing , at least one of system bandwidth, the number of aggregated time-domain resource units, and the number of symbols mapped to the reference signal in the aggregated time-domain resource; generating the reference signal according to the configuration information. The method and device for configuring a reference signal of the present application can propose a new reference signal design for a communication system, so as to meet the configuration requirements of the communication system.

Description

Technical field[0001]This application relates to the field of communication technology, and more specifically, to a method and device for configuring a reference signal.Background technique[0002]In the Long Term Evolution (LTE) system, data detection and demodulation are based on reference signals. The receiving end obtains the reference signal base sequence through configuration information or predefined information, and performs channel estimation based on the sequence and the received reference signal, estimates the channel of the data corresponding to the reference signal, and detects the data according to the channel And demodulation.[0003]In the LTE system, the transmission characteristics of the same frequency band and the same time unit are the same. For example, the transmission characteristics of the same frequency band and the same time unit are all uplink or all downlink. Among them, the reference signal base sequence is determined and the reference signal is mapped. And...
