Abstract: Various embodiments provide a frequency hopping processing method and a device. In those embodiments, a symbol used to transmit a demodulation reference signal of a shared channel can be determined by a communications device. A time domain frequency hopping location of the shared channel based on the symbol used to transmit the demodulation reference signal can be determined by the communications device. In this way, frequency hopping processing of a shared channel in an NR network is implemented.

Abstract: Embodiments of this application provide a method and apparatus for determining a transport block size. The method includes: obtaining a target overhead value based on a target time-frequency resource and one or more of at least two overhead values, where the target time-frequency resource is used for uplink data transmission or downlink data transmission and includes one or more time-frequency resource units, and each overhead value is corresponding to at least one time-frequency resource unit; and determining a transport block size based on the target overhead value. It can be learned that, according to the method and apparatus for determining a transport block size provided in the embodiments of this application, a corresponding target overhead value may be determined for each of different target time-frequency resources. This is not only applicable to a scenario in which a dynamic time-frequency resource is scheduled, but also improves accuracy of determining the transport block size. Therefore, transmission performance is improved.
