Resource allocation method, network device, and terminal device
First Claim
1. A resource allocation method, comprising:
- receiving, by a terminal device, downlink control information, wherein the downlink control information comprises a first information field and a second information field, and the first information field is used to indicate to the terminal device whether to switch a first active bandwidth part of the terminal device;
determining, by the terminal device based on the second information field, one or more second active bandwidth parts and a frequency domain resource of a data channel in the one or more second active bandwidth parts to which the terminal device switches, in response to the first information field indicating to the terminal device to switch the first active bandwidth part; and
determining, by the terminal device, a frequency domain resource of a data channel in the first active bandwidth part based on the second information field, in response to the first information field indicating to the terminal device not to switch the first active bandwidth part.

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.

11. A terminal device, comprising:
-
a receiving module, configured to receive downlink control information, wherein the downlink control information comprises a first information field and a second information field, and the first information field is used to indicate to the terminal device whether to switch a first active bandwidth part of the terminal device; a processing module, configured to; determine, based on the second information field, one or more second active bandwidth parts and a frequency domain resource of a data channel in the one or more second active bandwidth parts to which the terminal device switches, in response to the first information field indicating to the terminal device to switch the first active bandwidth part; and determine a frequency domain resource of a data channel in the first active bandwidth part based on the second information field, in response to the first information field indicating to the terminal device not to switch the first active bandwidth part. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
