Abstract: This application provides a DMRS sending method, a DMRS receiving method, and a communication apparatus. The method includes: receiving indication information indicating a scheduled DMRS port; and sending a DMRS on the scheduled DMRS port. The scheduled DMRS port belongs to a DMRS port set, the DMRS port set includes M DMRS ports, the M DMRS ports correspond to a first time domain position and a second time domain position, and a first DMRS port set corresponding to the first time domain position is different from a second DMRS port set corresponding to the second time domain position. In this way, different DMRS port sets are mapped to the first time domain position and the second time domain position, so that more orthogonal DMRS ports can be supported, thereby improving a system capacity.

Abstract: A first access network device determines a timing offset of a first carrier and a second carrier. The timing offset is an offset between timing of downlink communication of the first carrier and timing of uplink communication of the second carrier. The first carrier is a carrier using a first radio access technology (RAT), and the second carrier is an uplink frequency division duplex (FDD) carrier using the first RAT and a second RAT. The first access network device sends first indication information to a terminal. The first indication information indicates the timing offset, and the timing offset is used to determine the timing of the second carrier. Based on this scheme, the terminal can use a shared frequency band resource of LTE, thereby improving resource utilization.

Abstract: A reference signal sending method, a reference signal receiving method, and an apparatus are provided. A first network device determines a first resource. The first network device generates a reference signal corresponding to the first resource. The reference signal includes M parts, and all of the M parts are the same. The first resource does not carry a cyclic postfix of the reference signal. Alternatively, the first resource carries a cyclic prefix of the reference signal and the cyclic prefix corresponding to the reference signal is located only at the start of the 1st part in the M parts. M is a positive integer. The first network device sends the reference signal to a second network device on the first resource.

Abstract: Various embodiments provide a communication method, a communications apparatus, and a computer-readable storage medium. In those embodiments, a first transmit power can be determined for transmitting first information in a first time unit on a first carrier and a second transmit power can be determined for transmitting second information in a second time unit on a second carrier. A third transmit power can be determined for transmitting the second information in a first time period and transmitting the second information in a second time period using the second transmit power or the third transmit power. The second information can be sent in the first time period using the third transmit power. In those embodiments, a sum of powers used by a terminal device to transmit two uplink carriers in a same time period does not exceed a maximum transmit power of the terminal device.
