Abstract: This disclosure provides example reference signal mapping methods, apparatuses, and media. One example method includes determining a time-frequency unit based on a size of a first frequency domain unit. A resource group in the time-frequency unit is determined based on a first port index, where the resource group corresponds to one port group, and the port group includes one or more ports. A reference signal corresponding to the first port index is mapped to a first resource group in the time-frequency unit in response to determining that a port corresponding to the first port index belongs to a first port group, or the reference signal corresponding to the first port index is mapped to a second resource group in the time-frequency unit in response to determining that a port corresponding to the first port index belongs to a second port group. The reference signal is sent.

Abstract: A precoding matrix indication method and a related device. In the method, a transmit end can group K combination coefficients based on an amplitude value of each of the K combination coefficients, to obtain Q combination coefficient groups, and determine a phase value of each combination coefficient in each combination coefficient group. The amplitude value of each combination coefficient is determined by using a same amplitude quantization bit quantity and a same amplitude quantization rule. In addition, phase quantization bit quantities and/or phase quantization rules used by at least two of the Q combination coefficient groups are different.

Abstract: This application provides an example communication method and an example apparatus. The method includes a first network device generates first indication information to indicate a first downlink resource. Second indication information indicates a second downlink resource. Because the first indication information may indicate whether the second indication information exists, if a terminal device detects the first indication information in the first time unit, and the first indication information indicates that the second indication information does not exist in the first time unit, the terminal device may stop a blind detection process on the second indication information in advance.
