摘要： A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.

摘要： Example channel transmission methods and apparatus are described. One example method includes determining search spaces of at least two downlink control channels by a first network device. The first network device separately determines in the search spaces resources occupied by the at least two downlink control channels. Resource scheduled by the at least two downlink control channels belong to one carrier. The first network device obtains the at least two downlink control channels by using the resources. With the embodiments of the present invention, data on one carrier can be scheduled through a plurality of downlink control channels.

摘要： 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.
