Bandwidth Resource Configuration Method, Apparatus, and System

An apparatus, comprising:

• a non-transitory memory;
• at least one processor coupled to the memory, wherein the at least one processor is configured to execute a program stored in the memory to:
• transmit a first control channel and a first data channel to a terminal in a first bandwidth part;
• transmit information about a second bandwidth part to the terminal in a third bandwidth part, wherein the second bandwidth part is a bandwidth part to be switched to by the terminal, and wherein:
• the third bandwidth part is an access bandwidth part;
• or
• the third bandwidth part is comprised in one or more candidate operating bandwidth parts of the terminal;
• and
• transmit a second control channel and a second data channel to the terminal in the second bandwidth part.

A non-transitory computer-readable storage medium storing program instructions, wherein the program instructions are configured to be executed by a processor of an apparatus to cause the apparatus to:

• transmit a first control channel and a first data channel to a terminal in a first bandwidth part;
• transmit information about a second bandwidth part to the terminal in a third bandwidth part, wherein the second bandwidth part is a bandwidth part to be switched to by the terminal, and wherein:
• the third bandwidth part is an access bandwidth part;
• or
• the third bandwidth part is comprised in one or more candidate operating bandwidth parts of the terminal;
• and
• transmit a second control channel and a second data channel to the terminal in the second bandwidth part.
