A.
Geographically directly relatedNeighboring cells are generally used as neighboring cells
B.
For dense urban areas and ordinary urban areas, the distance between stations is relatively close (0.3-1.0kilometer),Neighborhood should do more
C.
becauseforLTEofThe neighboring area does not exist in orderI,CanProblem, and the detection cycle is very short, so you only need to consider not missing neighbors, not wantSort neighboring cells strictly according to signal strength

Question 15
What are the principles that need to be followed when planning LTE neighboring cells? (Multiple choice)
A.
Neighborhoods that are directly adjacent to the geographic location are generally regarded as neighboring cells
B.
For dense urban areas and ordinary urban areas, due to the relatively close distance between stations (0.3-1.0 km), neighbouring areas should do more
C.
Because there are no sequential I and possible questions in LTE neighboring cells, and the detection period is very short, it is only necessary to consider not missing neighboring cells, and it is not necessary to sort neighboring cells strictly according to signal strength.
D.
Turn on ANR to completely replace the neighborhood planning of the initial network
