Abstract

The present invention provides an information transmission method, a data demodulation method, an information transmission device, a data demodulation device, a communication node, and a network sidedevice. The information transmission method comprises the step that: a first communication node transmits first demodulation reference signals in a first time slot, and the candidate locations of thefirst demodulation reference signals in the first time slot at least partially overlap with the candidate locations of second demodulation reference signals in a second time slot, wherein the second time slot is a time slot by which a second communication node transmits the second demodulation reference signals, and the transmission direction of the first demodulation reference signals in the first time slot is different from the transmission direction of the second demodulation reference signals in the second time slot. With the information transmission method, the data demodulation method, the information transmission device, the data demodulation device, the communication node, and the network side device of the invention adopted, the problem that the locations of demodulation referencesignals in time slots are not set in the prior art can be solved, and the detection of interference between uplink and downlink demodulation reference signals can be ensured.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an information transmission and data demodulation method and device, a communication node, and a network side device. Background technique [0002] Currently, the physical layer technology of the New Radio (NR) is under intense discussion in the 3rd Generation Partnership Project (3GPP) RAN1. Flexibility and efficiency have always been the goal of NR physical layer design. It seems that the pursuit of maximum flexibility for physical layer reference signals has also become a trend. This is because different application scenarios may have different requirements for demodulating the reference signal. [0003] For users with relatively high delay requirements, users need to receive downlink data in one time slot and then feed back to the base station a signal indicating whether the corresponding downlink data transmission is correct or not. That is to say, the downlink physical...
