How to calculate the coverage of 5g cell


First of all, you have to have a goal, you have to give a condition to meet the coverage. Data services generally use the rate as the coverage target, such as 1Mbps, and then simulate the user behavior through simulation to get the user's rate distribution and see how far the point that can reach 1Mbps is from the base station. If the conditions change, the coverage distance will change.


In addition: the NCS of PRACH (determined by zero correlation zone config) also directly determines the cell radius

Cell radius < light speed / PRACH_ SCS * NCS / PRACH_ Sequence points / 2


For example, short code 139, PRACH SCS = 30K, NCS = 34 (zero correlation zone config = 13)

Then the radius of the cell is less than

3*10^8 / 30000 * 34 / 139 / 2 = 1223m

If the distance of the base station is greater than this value, the mobile phone cannot connect to the base station. It's like a cell phone signal being jammed or blocked.
