Spectrum resource configuration method, network device, and system

A network device, comprising:

• computing hardware;
• and
• a non-transitory computer-readable storage medium including computer-executable instructions executed by the computing hardware to perform operations comprising:
• determining spectrum resources to be used by a to-be-opened channel, wherein the spectrum resources to be used by the to-be-opened channel comprise first spectrum resources and a second spectrum resource, the first spectrum resources are original spectrum resources of the to-be-opened channel, the second spectrum resource is part of original spectrum resources of at least one adjacent channel of the to-be-opened channel, and the original spectrum resources of the at least one adjacent channel are adjacent to the original spectrum resources of the to-be-opened channel, wherein the second spectrum resource comprises at least one spectrum slice of a first adjacent channel of the at least one adjacent channel, and a quantity of spectrum slices borrowed from the first adjacent channel is less than or equal to a half of a quantity of original spectrum slices of the first adjacent channel, and wherein the first adjacent channel is opened and has a lower priority than the to-be-opened channel;
• and
• opening the to-be-opened channel based on the spectrum resources to be used by the to-be-opened channel.

A system, comprising:

• at least two network devices, wherein a first network device of the at least two network devices is configured to:
• determine spectrum resources to be used by a to-be-opened channel, wherein the spectrum resources to be used by the to-be-opened channel comprise first spectrum resources and a second spectrum resource, the first spectrum resources are original spectrum resources of the to-be-opened channel, the second spectrum resource is part of original spectrum resources of at least one adjacent channel of the to-be-opened channel, and the original spectrum resources of the adjacent channel are adjacent to the original spectrum resources of the to-be-opened channel, wherein the second spectrum resource comprises at least one spectrum slice of a first adjacent channel of the at least one adjacent channel, a quantity of spectrum slices borrowed from the first adjacent channel is less than or equal to a half of a quantity of original spectrum slices of the first adjacent channel, and wherein the first adjacent channel is opened and has a lower priority than the to-be-opened channel;
• and
• open the to-be-opened channel based on the spectrum resources to be used by the to-be-opened channel.
