    Abstract: This application provides a communication method and an apparatus. A terminal device receives a first indication information from a network device, where the first indication information indicates a first parameter combination including at least two of the following: a first value of Mv, a first value of β, and a first value of α. The first parameter combination is for determining that a first coefficient matrix to be indicated by the terminal device includes a maximum of K0 non-zero elements, and K0 is determined based on the first values of Mv, β, and α. The terminal device sends a second information indication to the network device, where the second indication information indicates K2 non-zero elements in the first coefficient matrix, and K2 is less than or equal to K0.

    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: This application provides a technical solution for rank indication, and especially when a CQI number is not configured or a CQI number is 1, a network device configures a rank indication restriction parameter as that at least one of ranks whose index numbers are 0, 1, 2, and 3 is allowed to be reported by the terminal device; or even if the network device does not perform the foregoing configuration, and none of the ranks whose index numbers are 0, 1, 2, and 3 is allowed to be reported, the terminal device may select at least one rank for RI reporting, so as to resolve a problem that a system cannot work. In addition, according to embodiments of this application, bit overheads required for RI reporting may further be reduced.

    Abstract: This application provides a resource indication method, a terminal device, and a network device. The method includes: determining time domain positions of demodulation reference signals (DMRSs) 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, where 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.
