Embodiment Construction

[0044] The nonlinear processing link of the nonlinear precoding technology includes a power adjustment operation and a filtering operation. The power adjustment operation is used to adjust the power of the signal to be transmitted. The filtering operation is used to pre-eliminate the interference generated by the signal to be transmitted through the channel. Wherein, the signal to be sent includes one or more symbols to be sent. The symbols to be transmitted refer to constellation symbols (or modulation symbols) obtained by constellation mapping (ie modulation) of coded bits (or coded bit stream). In this embodiment of the present application, the signal to be sent generally refers to a data signal. In the following, the power adjustment operation and the filtering operation on symbols to be transmitted are taken as an example for description.

[0045] The embodiment of the present application does not limit the nonlinear precoding technology applicable to the embodiment of...

Abstract

The embodiment of the invention discloses a parameter configuration method and device, relates to the technical field of communication, and the method and the device are helpful for meeting the flexibility requirement of a system so as to improve the overall performance of the system. The method comprises the steps that parameter configuration signaling is generated, the parameter configuration signaling is used for configuring N VRB values, N is larger than or equal to 1, and N is an integer; wherein the N VRB values have a corresponding relationship with at least one of the following parameters of the to-be-sent signal: a transmission layer, an antenna port, a code word, a modulation order and an MCS; and the parameter configuration signaling is sent.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular, to a parameter configuration method and device. Background technique [0002] A multiple input multiple output (MIMO) system generally uses a precoding technique to improve channels, so as to enhance the effect of spatial multiplexing (spatial multiplexing). The precoding technology uses a precoding matrix that matches a channel to process a spatially multiplexed data stream (hereinafter referred to as a spatial stream), thereby realizing precoding of a channel and improving the receiving quality of the spatial stream. [0003] Precoding techniques include linear precoding techniques and nonlinear precoding techniques. The nonlinear precoding technology can be considered as introducing a nonlinear processing link on the basis of the linear precoding technology. During the nonlinear processing of the signal, the transmission power of the sign...
