Technical field

The present invention relates to the field of communications technologies, and in particular, to a resource scheduling method, apparatus, and communication system.

Background technique

The new wireless (NR, New radio) system supports three major scenarios: enhanced mobile broadband (eMBB), ultra-large-scale device access (mMTC), and low latency high-reliability communication (URLLC). Different scenarios have different key parameter requirements. For example, enhanced mobile broadband is designed to greatly increase system capacity, ultra-large-scale device access is designed to meet the access of large-scale devices, and low-latency, high-reliability communication is designed to provide low latency and high reliability communications.
