Abstract
Provided are information transmission and data demodulation methods and apparatuses, a communication node, and a network side device. The information transmission method includes: transmitting, by a first communication node, a first demodulation reference signal within a first slot, where candidate positions of the first demodulation reference signal within the first slot at least overlap with candidate positions of a second demodulation reference signal within a second slot, the second slot is a slot within which a second communication node transmits the second demodulation reference signal, and a transmission direction of the first demodulation reference signal within the first slot is different from a transmission direction of the second demodulation reference signal within the second slot.
