A communication method, comprising:
- reporting, by a terminal, demodulation reference signal (DMRS) bundling capability information supported by the terminal as a terminal capability, wherein the DMRS bundling capability information indicates whether the terminal supports DMRS bundling across slots or across repeated transmissions;
- receiving, by the terminal, configuration information of a DMRS bundling from a network device, wherein the configuration information comprises time range information of the DMRS bundling required for the terminal;
- and
- performing, by the terminal, an uplink channel transmission based on the configuration information of the DMRS bundling;
- wherein a maximum allowable phase difference within a time range is specified for the DMRS bundling, and the DMRS bundling meets following conditions:
- the DMRS bundling is used for back-to-back physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) transmission;
- a frequency domain position does not change;
- and
- no frequency hopping occurs between the slots or within a slot.
