Abstract

The invention discloses an uplink pre-coding method and system and a storage medium, and the method comprises the steps: obtaining a calibration matrix, a sending pre-decoupling matrix and a receiving decoupling matrix based on a calibration signal of a terminal calibration receiving and transmitting antenna and a terminal receiving and transmitting array, and employing the calibration matrix, sending pre-decoupling matrix and receiving decoupling matrix. The initial uplink precoding matrix is pre-decoupled and calibrated by sending the pre-decoupling matrix and the calibration matrix to obtain the final uplink precoding matrix, so that the coupling effect interference can be effectively eliminated, uplink calibration is performed, and the uplink transmission performance is enhanced.

Description

technical field [0001] The invention relates to an uplink precoding method, system and storage medium, and belongs to the technical field of wireless communication transmission. Background technique [0002] In the uplink transmission of 5G-NR, the use of uplink multi-antenna technology on the terminal side can significantly improve the uplink capacity. Currently, 5G commercial terminals can use 2 to 4 transmit antennas, and 5G-NR uplink multi-antenna precoding can use codebook-based precoding or non-codebook precoding that relies on reciprocity. However, in an actual commercial terminal, due to the limitation of the size of the terminal side, there is a coupling effect in the multi-antenna array, which will reduce the uplink transmission performance. Contents of the invention [0003] The invention provides an uplink precoding method, system and storage medium, which solves the problem that the coupling effect reduces the uplink transmission performance. [0004] In ord...
