Solution Approach 2:

The system employs configurable parameters including subcarrier spacing values, cyclic prefix lengths, and resource block sizes that can be adjusted according to different service requirements. By changing these parameters, the base station can optimize performance for various scenarios (eMBB, mMTC, URLLC) without fundamentally altering the system architecture, thus improving adaptability while controlling complexity.

AI summary

Terminal device receives a SS/PBCH block and a high-layer parameter and determines a point A. A common resource block is determined at least based on a subcarrier 0 of the SS/PBCH block. The point A is determined at least based on a subcarrier 0 of the common resource block and an offset provided by the high-layer parameter. The offset is expressed in units of resource blocks assuming 120 KHz for FR2-2.
