method and apparatus for obtaining the reference signal, and computer-readable storage medium

摘要

this order refers to the field of mobile communications and, in particular, a technology for obtaining a reference signal in a wireless communications system. in a method for obtaining a reference signal, a terminal device obtains position shift information; the terminal device obtains a first sequence based on the position shift information; and the terminal device demodulates, using the first sequence, a control channel signal carried on a set of control channel resources, to obtain downlink control information. in this way, mu-mimo transmission performance is improved.
