摘要： Embodiments of this application provide a data transmission method and a communication apparatus. The method includes: A network device sends first information to a terminal device, where the first information is used to indicate transport block size TBS configuration information and/or redundancy version RV configuration information, the TBS configuration information is used to configure a first transport block size TBS, and the RV configuration information is used to configure first RV information. The network device receives a transport block from the terminal device, or the network device sends a transport block to the terminal device, where a TBS of the transport block is the first TBS, and/or RV information of the transport block is the first RV information. The network device may expand a TBS and/or refine an RV by using the TBS configuration information and/or the RV configuration information, thereby improving a spectral efficiency when the TB is transmitted.

摘要： 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.

摘要： In a demodulation reference signal (DMRS) configuration method, a network device sends first scheduling information to a terminal device. The terminal device determines, based on the first scheduling information, whether a transmission of a first time unit meets a condition of having the same transmit power, same precoding, same antenna port, or a same frequency domain resource as the transmission of a second time unit. The second time unit is before the first time unit and has a transmission direction that is the same as a transmission direction in the in the first time unit, and no transmission in an opposite direction exists between the second time unit and the first time unit. When the first time unit meets the above condition, the terminal device sends uplink data in the first time unit and the second time unit, or receiving downlink data in the first time unit and the second time unit.

摘要： 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.

摘要： This application discloses a communication method and apparatus, to resolve an existing problem that a large quantity of time-frequency resources are occupied for indicating a quantity of repeated transmissions of a Msg 3. The method includes: A terminal device receives first information. The terminal device obtains first indication information based on a shared bit in the first information. The first indication information indicates a quantity of repeated transmissions of a third message Msg 3. The third message Msg 3 is a radio resource control RRC connection request in a random access procedure. The shared bit is shared by the first indication information and the first information. The terminal device determines the quantity of repeated transmissions of the third message based on the first indication information.
