Resource indication method and related device

A resource indication method, comprising:

• receiving, by a user equipment, an indication from a network device using a first system resource for a first system, wherein the indication indicates system resource information of a second system, wherein a single carrier of the second system occupies a preset quantity of resource blocks in the first system, and wherein the preset quantity is a rounded-up ratio of a second frequency width of the single carrier of the second system to a first frequency width of a resource block in the first system;
• determining, by the user equipment, the system resource information based on the indication;
• and
• accessing, by the user equipment, the second system using the system resource information.

A system deployment method, comprising:

• determining, based on resource block information of a plurality of resource blocks that are part of a first system and information of a single carrier in a second system, at least one piece of candidate resource information of a single carrier deployed in the first system;
• determining system resource information of the second system from the at least one piece of the candidate resource information, wherein the resource block information comprises a frequency range of each resource block in the resource blocks, and wherein the information of the single carrier in the second system comprises a second frequency width of the single carrier in the second system;
• and
• implementing a function of deploying the second system in the first system when a spacing among subcarriers of the first system is different from a spacing among subcarriers of the second system.
