Abstract

Embodiments of the present 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 the transmission block size TBS configuration information and / or the redundancy version RV Configuration information, where the TBS configuration information is used to configure the first transport block size TBS, and the RV configuration information is used to configure the first RV information; the network device receives the transport block from the terminal device, or the network device sends the transport block to the terminal device ; wherein the TBS of the transport block is the first TBS, and / or the RV information of the transport block is the first RV information. In the method of this embodiment of the present application, the network device can extend the TBS and / or the refined RV through the TBS configuration information and / or the RV configuration information, so that the network device and the terminal device can use the extended TBS and / or the refined RV for TB transmission , improving the spectral efficiency when transmitting TB.

Description

technical field [0001] The embodiments of the present application relate to communication technologies, and in particular, to a data transmission method and a communication device. Background technique [0002] At present, the new air interface (new radio, NR) system adopts the following methods to ensure the transmission of TB on the uplink data channel and the downlink data channel: 1. Adaptive modulation and coding (AMC) method is adopted for uplink data The TB to be transmitted on the channel and the downlink data channel are modulated and coded to select an appropriate modulation and coding method to adapt to the quality of the wireless channel and ensure the transmission quality of the link. 2. Use low density parity check coding (LDPC) to encode and decode the TB to be transmitted on the uplink data channel and downlink data channel, so as to enhance the reliability of data transmission by adding check bits. 3. Adopt hybrid automatic repeat-request (HARQ) technology ...
