Title:
METHOD AND DEVICE FOR TRANSMITTING REFERENCE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/157737
Kind Code:
A1
Abstract:
The present application provides a method for transmitting a reference signal sequence, comprising: generating a reference signal sequence according to a frame number of a radio frame; mapping at least a part of the reference signals in the reference signal sequence to a resource location used for transmission of the at least part of the reference signals and that corresponds to the radio frame; and transmitting the at least part of the reference signals at the resource location, or transmitting an orthogonalized reference signal, the orthogonalized reference signal being obtained by multiplying the at least part of the reference signals by a preset orthogonal code. During generation of a reference signal sequence, the reference signal sequence is generated according to a frame number of a radio frame, such that reference signal sequences in any two radio frames in each cell are different, thereby reducing interference caused by a reference signal of an interfering cell to a reference signal of a current cell when a receiving device performs same-phase combination on reference signal sequences in a plurality of received radio frames.
