    Abstract: This application provides a data transmission method. The method includes: when transmitting at least one transport block TB for the first time, sending, by a first device, first control information to a second device, where the first control information includes a modulation and coding scheme MCS field; and when retransmitting the TB, sending, by the first device, second control information to the second device, where the second control information includes a first field but does not include the MCS field, and the first field includes information about a relationship between retransmitted data and the TB.

    Abstract: This application discloses a communication method that includes: receiving first control information of a first bandwidth part (BWP) and second control information of a second BWP, and receiving a first data channel and a second data channel based on the first control information. The first BWP includes a first frequency domain resource and a second frequency domain resource. The second BWP includes a third frequency domain resource, and the third frequency domain resource and the second frequency domain resource overlap. The first data channel is located on the first frequency domain resource, and the second data channel is located on the third frequency domain resource. The foregoing method provides a manner of transmitting data on the first and second BWPs that partially overlap.

    Abstract: A communication method and apparatus, and a readable storage medium are provided. A network coding NC parameter corresponding to a received index is determined based on a correspondence between the index and an NC parameter, and the NC parameter is applied to NC processing. According to this application, NC processing can adapt to a channel quality state, so that transmission reliability can be ensured and spectrum utilization efficiency can be improved. This application may be applied to an extended reality XR service, a scenario with a low latency and/or a scenario with a large uplink capacity.
