Abstract

The present invention provides a channel and signal transmission method and communication equipment, belonging to the field of communication technology, wherein the channel and signal transmission method applied to the communication equipment at the sending end includes: when transmitting at least two data transmission resources, according to the At least one of quasi-co-location QCL information and preset rules of the data transmission resource to send the data transmission resource, where the data transmission resource is at least one of a signal and a channel. The technical solution of the present invention can make the base station and the terminal understand the relevant parameters of the channel and signal to be transmitted consistent, such as determining whether multiple channels and signals can be multiplexed and transmitted on the same symbol at the same time, and the QCL information used, so that the channel and signal can be realized. correct transmission of signals.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a channel and signal transmission method and communication equipment. Background technique [0002] Long Term Evolution (LTE) / LTE-Advanced (LTE-A) and other wireless access technology standards are based on multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) + orthogonal frequency division It is built on the basis of Orthogonal Frequency Division Multiplexing (OFDM) technology. Among them, the MIMO technology utilizes the spatial freedom obtained by the multi-antenna system to improve the peak rate and the utilization rate of the system spectrum. [0003] In the process of standardization development, the dimensions of MIMO technology continue to expand. In LTE Rel-8, up to 4 layers of MIMO transmission can be supported. Enhanced Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology in Rel-9, transmission mode (Transmission Mode, TM)-8 ...
