Indication method, processing method, and apparatus

A network device comprising:

• a processing unit configured to:
• configure M bandwidth parts (BPs) for at least one terminal device, wherein the M BPs are located on one frequency domain resource, and M is an integer greater than or equal to 1;
• and determine first indication information related to X BPs in the M BPs, wherein the first indication information comprises at least one field, each field being used to indicate transmission types in at least one time unit on the X BPs, and X is a positive integer less than or equal to M;
• and
• a sending unit configured to:
• send the first indication information to the at least one terminal device, wherein the at least one terminal device comprises a first terminal device;
• and send second indication information to the first terminal device, wherein the second indication information is used to indicate an index relationship between at least one of N BPs configured for the first terminal device and the at least one field in the first indication information, and N is a positive integer less than or equal to X.

A terminal device comprising:

• a receiving unit configured to:
• receive first indication information from a network device, wherein the first indication information comprises at least one field used to indicate transmission types in at least one time unit on N bandwidth parts (BPs), the N BPs are N BPs in Q BPs configured by the network device for the first terminal device, the Q BPs are located on one frequency domain resource, Q being an integer greater than or equal to 1, and N being a positive integer less than or equal to Q;
• and receive second indication information from the network device, wherein the second indication information is used to indicate an index relationship between at least one of the N BPs and the at least one field in the first indication information;
• and
• a processing unit being configured to:
• determine, based on the index relationship and the first indication information, a field corresponding to at least one of the N BPs, and determine the transmission types in the at least one time unit on the at least one N BP based on the determined field.
