1. A communication method, comprising:
receiving first information, second information, third information, and fourth information from a first network device, wherein the first information indicates a position of a time-frequency resource occupied by a physical downlink control channel (PDCCH) control resource set (CORESET) of a second network device; the second information indicates that each demodulation reference signal (DMRS) code division multiplexing (CDM) group comprised in a DMRS symbol occupies n resource elements (REs) consecutive in frequency domain, wherein n is a positive integer and is greater than 2; the third information indicates a symbol position of the DMRS symbol in a different-configuration slot; the fourth information indicates one or more time domain positions of at least one different-configuration slot; and the first network device is located within coverage of the second network device;
receiving uplink grant information from the first network device, wherein the uplink grant information indicates a position of a time-frequency resource for uplink data of a terminal device; and
sending the DMRS symbol to the first network device in a first different-configuration slot based on the second information and the third information, wherein the first different-configuration slot is at least one of the at least one different-configuration slot, and the position of the time-frequency resource occupied by the uplink data of the terminal device overlaps, in the first different-configuration slot, the position of the time-frequency resource occupied by the PDCCH CORESET.
