Variable bandwidth-based communication method and apparatus

A variable bandwidth-based communication method applied in a terminal, comprising:

• receiving indication information and a bandwidth parameter list from a network node, wherein the indication information and the bandwidth parameter list are used to indicate a target scheduling bandwidth used by a serving cell corresponding to the terminal;
• wherein
• the bandwidth parameter list comprises at least one group of bandwidths and parameter indexes corresponding to the at least one group of bandwidths, the at least one group of bandwidths comprises the target scheduling bandwidth, the indication information indicates a first parameter index corresponding to a target scheduling bandwidth parameter, the first parameter index is one parameter index of the parameter indexes;
• obtaining the target scheduling bandwidth based on the indication information and the bandwidth parameter list;
• and
• communicating with the network node based on the target bandwidth parameter.

An apparatus, comprising:

• a processor;
• and
• a non-transitory memory, wherein the memory stores execution instructions;
• and when the processor executes the execution instructions, the apparatus is enabled to perform the following operations:
• receiving indication information and a bandwidth parameter list from a network node, wherein the indication information and the bandwidth parameter list are used to indicate a target scheduling bandwidth used by a serving cell corresponding to the apparatus;
• wherein
• the bandwidth parameter list comprises at least one group of bandwidths and parameter indexes corresponding to the at least one group of bandwidths, the at least one group of bandwidths comprises the target scheduling bandwidth, the indication information indicates a first parameter index corresponding to a target scheduling bandwidth parameter, the first parameter index is one parameter index of the parameter indexes;
• obtaining the target scheduling bandwidth based on the indication information and the bandwidth parameter list;
• and
• communicating with the network node based on the target bandwidth parameter.
