Problems solved by technology

In the prior art, it may happen that the time-frequency resource position mapped by the DMRS sent by the transmission point to the receiving point overlaps with the time-frequency resource position mapped by the data sent by another coordinated transmission point to the receiving point , which will cause the receiving point to be unable to receive the DMRS correctly, which in turn will cause the receiving point to be unable to correctly estimate the channel, the data receiving performance of the receiving point will decrease, and the system performance will decrease

Abstract

The embodiment of the invention discloses a communication method, related equipment and a related system. The method comprises the steps as follows: a receiving points receives a first instruction that is used for instructing a time frequency resource position of a first demodulation reference signal of first data; the receiving point receives a second instruction that is used for instructing a time frequency resource position of a second demodulation reference signal; and the receiving point determines the time frequency resource position of the first data according to the time frequency resource position of the second demodulation reference signal, and demodulates the first data according to the first demodulation reference signal. The receiving performance of the receiving point can beenhanced.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a communication method, related equipment and system. Background technique [0002] In a Multiple-Input Multiple-Output (MIMO) communication system, multiple sources and / or destinations (e.g., corresponding to each antenna) may be used to transmit and receive information between devices in the communication system data, control signaling and / or other information. In some cases, the illustrated transmissions associated with a MIMO communication system using multiple sources and / or destinations can result in higher data rates, improved signal quality, and other similar aspects as compared to a single-input single-output communication system. advantage. [0003] An example of a MIMO communication system is a coordinated multipoint transmission (Coordinate MultipointTransmission, CoMP) system, in which multiple transmission points (Transmission Point, T...
