    Abstract: This application provides one or more resource indication methods, terminal devices, and network devices. An example method includes: receiving, by the terminal device, the first indication information, and determining time domain positions of a demodulation reference signal (DMRS) based on the mapping type of the physical shared channel and with reference to a position index of the last symbol occupied by the physical shared channel or a quantity of symbols occupied by the physical shared channel in the resource unit. The position index of the last symbol occupied by the physical shared channel in the resource unit corresponds to the first type, and the quantity of symbols occupied by the physical shared channel in the resource unit corresponds to the second type.

    Abstract: A communication method, including performing, by a terminal device, in response to a value of a resource bundling granularity being a first-type value, determining at least one resource block bundling group in a scheduling resource corresponding to a terminal device according to the first-type value of the resource bundling granularity, wherein, the first-type value comprises 2 or 4, and receiving, using the at least one resource block bundling group, data transmitted by a network device. The method further includes performing, by the terminal device, in response to the value of the resource bundling granularity being a second-type value, determining a scheduling resource corresponding to the terminal device as a same resource block bundling group, wherein, the second-type value comprises a size of a consecutive scheduling bandwidth of the terminal device, and receiving, using the resource block bundling group, data transmitted by the network device.

    Abstract: This application discloses a DMRS indicating method, a DMRS receiving method, and an apparatus. The method includes: determining, by a transmit end from a plurality of groups of demodulation reference signal DMRS configuration information, DMRS configuration information corresponding to a current DMRS transmission scheme, and obtaining DMRS indication information based on the DMRS configuration information, where each group of DMRS configuration information includes a plurality of pieces of DMRS configuration information; and sending, by the transmit end, the DMRS indication information. The method and the apparatus provided in this application are implemented to match a plurality of scenarios in NR. This can satisfy a requirement for transmitting more layers of data, and can further reduce indication overheads.
