Sounding reference signal transmission method and apparatus

A method, wherein the method comprises:

• receiving first configuration information, wherein the first configuration information is used to configure a first periodicity, the first periodicity is less than first duration, and the first duration is related to load of a first cell at a first moment;
• and
• sending at least one first sounding reference signal based on the first periodicity, wherein the at least one first sounding reference signal is used to estimate channel quality of full bandwidth of operating bandwidth of the first cell.

A communication apparatus, comprising at least one processor, wherein the at least processor is coupled to a storage, the storage is configured to store a program or instructions, and when the program or the instructions are executed by the at least one processor, the communication apparatus is enabled to perform:

• receiving first configuration information, wherein the first configuration information is used to configure a first periodicity, the first periodicity is less than first duration, and the first duration is related to load of a first cell at a first moment;
• and
• sending at least one first sounding reference signal based on the first periodicity, wherein the at least one first sounding reference signal is used to estimate channel quality of full bandwidth of operating bandwidth of the first cell.
