Frequency domain resource configuration method and related apparatus

A method applied to an access network device, comprising:

• configuring a first frequency domain resource for a physical downlink shared channel (PDSCH) of a cell, wherein the first frequency domain resource occupies a part of an available bandwidth of the access network device;
• configuring a second frequency domain resource for the cell, wherein the second frequency domain resource is a frequency domain resource available to the cell for transmitting downlink information, the second frequency domain resource occupies a part of the available bandwidth of the access network device, and the second frequency domain resource at least partially overlaps the first frequency domain resource;
• and
• adjusting a bandwidth of the second frequency domain resource based on at least one of a physical resource block utilization of the cell or an amount of downlink data of a terminal device in the cell.

An apparatus, comprising:

• a processor and a memory coupled to the processor with computer readable instructions stored thereon, wherein the instructions, when executed by the processor, enable the apparatus to perform:
• configuring a first frequency domain resource for a physical downlink shared channel (PDSCH) of a cell, wherein the first frequency domain resource occupies a part of an available bandwidth of an access network device;
• configuring a second frequency domain resource for the cell, wherein the second frequency domain resource is a frequency domain resource available to the cell for transmitting downlink information, the second frequency domain resource occupies a part of the available bandwidth of the access network device, and the second frequency domain resource at least partially overlaps the first frequency domain resource;
• and
• adjusting a bandwidth of the second frequency domain resource based on at least one of physical resource block utilization of the cell or an amount of downlink data of a terminal device in the cell.
