Abstract: A signal transmission method and an apparatus are provided. The method includes: A sending device generates a sequence of a demodulation reference signal, and maps the sequence of the demodulation reference signal to a time-frequency resource of the demodulation reference signal for sending. The demodulation reference signal is used to estimate a channel state of a first channel, and the first channel carries uplink data. The time-frequency resource includes frequency-domain resources corresponding to a first CDM group, and the frequency-domain resources corresponding to the first CDM group are non-contiguous and equally spaced.

Abstract: This application provides an uplink transmission method and an apparatus. The method includes: A network device indicates a terminal device to send a first transport block in a plurality of time units, and further indicates the terminal device to send uplink control information UCI in a first time unit. The first time unit is one of the plurality of time units. Regardless of whether the terminal device detects that the network device indicates the terminal device to send the UCI, both the network device and the terminal device calculate, based on a parameter G corresponding to the first time unit, a location of a starting bit in a coded bit sequence that is output through rate matching in a second time unit. The parameter G is a total quantity of coded bits available for transmission of the first transport block and the UCI in one time unit.

Abstract: This application provides a method for transmitting control information and an apparatus. The method includes: When a time domain resource for transmitting first control information on a first PUCCH conflicts in a first time unit with a time domain resource for transmitting a first transport block on a first PUSCH, a terminal device determines, based on a relationship between a payload size of the first control information and a first threshold, a first time domain resource for transmitting the first control information. The first threshold is a maximum quantity of bits of the first control information that can be sent by the terminal device in the first time unit without generating a first result. The first result is that some information bits in the first transport block cannot be transmitted. The terminal device transmits the first control information on the first time domain resource. By using the method, impact of the first control information on transmission of the information bits in the first transport block can be reduced, so that all information bits in a transport block can be transmitted, and transmission performance of the transport block on a PUSCH can be better ensured.

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.
