Abstract: This application describes a channel information feedback method and a communication apparatus. The method includes a terminal device that receives configuration information sent by a network device, where the configuration information is used to configure a feedback mode of channel information. The terminal device may feed back current channel information to the network device when the feedback mode configured by using the configuration information is a first mode. The terminal device may alternatively feeds back predicted channel information to the network device when the feedback mode configured by using the configuration information is a second mode. System performance is therefore improved by the method described in this application because channel information feedback requirements in different scenarios can be met. In particular, a problem that data transmission performance deteriorates because channel information expires in a moving scenario can be resolved by feeding back the predicted channel information.

Abstract: Embodiments of this application disclose a resource configuration method and apparatus, and a system. A network device sends, to a terminal device, resource configuration information of a demodulation reference signal DMRS resource that meets a predetermined rule. The terminal device receives the resource configuration information of a DMRS, where the received resource configuration information includes two or more groups, and the DMRS is used for demodulating a physical data channel. In the two or more groups of resource configuration information, a DMRS resource configured by any group of resource configuration information does not intersect with a physical data channel resource corresponding to another group of resource configuration information.
