Abstract: Example resource allocation methods and apparatus are described to resolve a problem of resource congestion and collision occurring in a communications system when virtual resource blocks (VRBs) scheduled for different terminal devices are mapped to physical resource blocks (PRBs). In one example method, system bandwidth of the communications system is divided into a plurality of fixed interleaving regions. Therefore, a network device can indicate a type of a virtual resource unit in a form of a frequency domain range occupied by one interleaving region. Using the foregoing solution can enable the network device to set the type of the virtual resource unit more conveniently.

Abstract: Disclosed are methods and systems for determining, by a terminal device, downlink control information that includes a first information field and a second information field. The first information field is used to indicate whether to switch an active bandwidth part of a terminal device. When the first information field indicates to switch the active bandwidth part of the terminal device, the second information field is used to indicate one or more active bandwidth parts and frequency domain resource location of a data channel in the active bandwidth parts to switch; or when the first information field indicates not to switch the active bandwidth part of the terminal device, the second information field is used to indicate a frequency domain resource location of a data channel in a currently accessed active bandwidth part. A working bandwidth part of the terminal device can be indicated, and resource utilisation is improved.
