摘要： This application provides a multi-downlink control information based transmission technology, in which a terminal reports information about a capability of the terminal to support multi-DCI transmission, or a network device sends indication information of types or a quantity of multi-DCI based transmissions to a terminal, and the network device performs resource scheduling on the terminal on this basis, thereby helping improve resource scheduling efficiency and reduce processing complexity of the terminal. In addition, this application also provides a corresponding solution for a scenario in which a CA/DC based transmission scenario coexists with multi-DCI based transmission, thereby helping the terminal share a multi-DCI based transmission capability and a CA/DC based transmission capability, and improve a processing capability of the terminal.

摘要： The present disclosure relates to a method for sending cell common control reference information. In one example method, before common control information needs to be sent, a base station having M antenna ports generates the cell control reference information used to detect the common control information. The base station maps the common control information and the cell control reference information to one or more resource units (RUs) of N antenna ports. The N antenna ports are a subset of the M antenna ports. The base station uses the one or more RUs to send the common control information and the cell control reference information used to detect the common control information to a user equipment (UE) within a coverage area of the base station.

摘要： 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.

摘要： 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.
