Abstract: Embodiments of the present invention provide a communication method. A first network device configures power configuration information for each of at least two precoding matrix groups, and sends the power configuration information to a second network device. The power configuration information is used to indicate a power configuration of a corresponding precoding matrix group of the at least two precoding matrix groups, and the at least two precoding matrix groups belong to a same resource used to measure channel state information CSI. When the second network device performs CSI measurement, different power values of different precoding matrix groups can be considered, thereby increasing accuracy of the CSI measurement.

Abstract: Embodiments of this application provide a signal transmission method and apparatus. In the embodiments of this application, a first device exchanges reference signal configuration information with a second device, to implement coordinated transmission of a reference signal sent by CoMP user equipment, so that the first device and the second device do not need to separately configure, for the CoMP user equipment, a resource used to transmit the reference signal. In addition, the CoMP user equipment sends a same reference signal to a plurality of devices (including the first device and the second device), so as to reduce delays in obtaining channel quality by different devices, and improve performance of coordinated transmission.

Abstract: Embodiments of this application provide a communication method and a communication apparatus. The method includes: A first communication apparatus receives a first indication parameter. There is a correspondence between the first indication parameter and first codeword-to-layer mapping. The first communication apparatus determines the first codeword-to-layer mapping based on the first indication parameter. Based on the method, in embodiments of this application, codeword-to-layer mapping can be dynamically adjusted and/or indicated. For example, a terminal device may use different codeword-to-layer mapping at different moments. For another example, different terminal devices may use different codeword-to-layer mapping at a same moment.

Abstract: The present disclosure relates to communication methods and apparatuses. In one example method, a first access network device determines configuration information, and sends the configuration information to a terminal. The first access network device is connected to a first core network device, and the first core network device uses a first or second communication standard. The configuration information includes status indication information of a first protocol layer (for example, a service data adaptation protocol (SDAP) layer) of the second communication standard, and the status indication information indicates the terminal to perform or not to perform a function of the first protocol layer. The first access network device determines a state of the first protocol layer based on a protocol layer specified in a communication standard of the core network device.
