  • Publication number: 20220322396
    Abstract: This application relates to the field of communications technologies, and discloses a method and an apparatus for indicating a number of repetitions, so that a configuration of a number of repetitions of an SRS and/or a PUSCH is more adaptive to a channel change. The method includes: A network device sends DCI to a terminal device, where the DCI includes first indication information, and the first indication information indicates a number of repetitions of an SRS and/or a PUSCH. Because the DCI has a faster update process than RRC signaling, and overheads are smaller than those of the RRC signaling, the network side device may flexibly configure the number of repetitions of the SRS and/or the PUSCH by using the DCI, to better adapt to the channel change, and further improve a channel estimation capability and signal demodulation performance.

  • Publication number: 20220116176
    Abstract: An embodiment method includes: determining, by a terminal device, at least one parameter based on first MCS information after receiving the first MCS information, where the at least one parameter is used to indicate a first reference signal pattern, so that the terminal device sends an uplink reference signal based on the first reference signal pattern; and determining, by a network device, the at least one parameter based on the first MCS information, where the at least one parameter is used to indicate the first reference signal pattern, so that the network device receives the uplink reference signal based on the first reference signal pattern.

  • Publication number: 20210314814
    Abstract: 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.
