Abstract: 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.

Abstract: This application relates to the field of communications technologies, and discloses a bandwidth indication method and apparatus, to provide a solution of indicating, by a base station, an allocated bandwidth part to a terminal when the terminal does not know a carrier bandwidth. The method is: determining, by the base station, a virtual bandwidth allocated to the terminal, where the virtual bandwidth is a part of a carrier bandwidth, and a bandwidth allocated to the terminal falls within the virtual bandwidth; and sending, by the base station, position information of the virtual bandwidth to the terminal, where the position information is used to indicate a position of the virtual bandwidth.

Abstract: An uplink resource grant method includes receiving, by a terminal, configuration information from a network device, where the configuration information includes information about a first uplink resource and information about a second uplink resource, and searching, by the terminal, a search space for a downlink control channel to obtain grant information. The search space includes a first control channel candidate set when the downlink control channel carries grant information of the first (or the second) uplink resource, and the search space includes a second control channel candidate set when the downlink control channel carries grant information of the second (or the first) uplink resource or grant information of a downlink resource. The first control channel candidate set is the same as the second control channel candidate set.
