Communication node pairing method and device, communication node and storage medium

[0054] The present application will be described in further detail below with reference to the accompanying drawings and examples.

[0055] In the relevant technique, the pairing scheme used is as follows:

[0056] Suppose a MIMO uplink system, the base station has 2 antennas, 2 single antenna users in the community, suppose they have paired success, the channel matrix of the 2 × 2VMIMO system composed is as follows:

[0057]

[0058] Where H 1 Hidden 2 A channel matrix composed of two configured users and base stations, respectively, which is independent of each other. At this time, the receiving signal vectors at the base station can be written as:

[0059]

[0060] Where X 1 X 2 Indicates that two transmitted signals for the user, n represents Gaussia white noise.

[0061] The mating is paired with the user of the selected channel that is most integrated with orthogonality, thereby transmitting user data through the same resource block. By system channel matrix H, calculate it
