Abstract: This application provides a Demodulation Reference Signal (DMRS) transmission method and a communications device. The method includes: determining, by a communications device, a current mode of a resource scheduling unit, where the current mode is a frequency hopping mode or an aggregation mode, and performing, by the communications device, DMRS mapping or demapping by using a DMRS pattern corresponding to the current mode, where a location of a symbol occupied by a DMRS in the DMRS pattern corresponding to the current mode is different from a location of a symbol occupied by a DMRS in a preset DMRS pattern. In embodiments of this application, a location of a symbol occupied by a DMRS can be flexibly selected depending on different modes. Therefore, requirements of the different modes can be satisfied in the embodiments of this application, thereby improving network performance.

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.
