Embodiment Construction

[0034] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0035] Before describing the embodiments of the present invention in detail, a brief description of the VP precoding technology is given first.

[0036] The VP precoding technology can obtain better performance than the traditional zero-forcing precoding technology, and is applicable to the downlink of both single-user systems and multi-user systems. In the VP precoding technology, the sending end selects a VP to reshape the transmitted symbols, and the receiving end uses a simple modulo operation to eliminate the VP and directly makes a judgment.

Abstract

A signal processing method, comprising: a terminal device receiving first precoding indication information, where the first precoding indication information is used to indicate information related to precoding a data signal; the terminal device based on the first precoding The instruction information processes the received data signal. And another signal processing method, terminal equipment, network equipment and storage medium.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a signal processing method, device and storage medium. Background technique [0002] The linear precoding technique is commonly used in existing NR communication systems. Although the complexity of the linear precoding technology is low, the precoding gain is relatively limited, especially in a multi-user-multiple-input-multiple-output (Multi-User Multiple-Input Multiple-Output, MU-MIMO) scenario. Therefore, nonlinear precoding has been extensively studied as an effective means to improve precoding gain. Among them, the vector perturbation (Vector Perturbation, VP) precoding technique is one of the nonlinear precoding techniques, which can provide better downlink transmission performance, and is applicable to the downlink of a single-user system and a multi-user system at the same time. However, the current New Radio (NR) system does not support the schem...
