measurementGap calculation

measurementGap is configured to UE for measuring different frequencies. Following notes should be considered when working with measurementGap.

1. Normal measurementGap configuration. Fully length is taken by UE.  
GapOffset 14
MGRP 40
MGL 6
T 4
GapSubframe 4

For above configuration, measurementGap will look like following every 40ms. 

subframe
SFN 0 1 2 3 4 5 6 7 8 9
0 - - - - - - - - - - -
1 GAP - - - - G G G G G G
2 - - - - - - - - - - -
3 - - - - - - - - - - -


2. Special measurementGap configuration. Fully length is taken by UE. 
GapOffset 29
MGRP 40
MGL 6
T 4
GapSubframe  9

For above configuration, measurementGap will look like following every 40ms. Note the shortened length of measurementGap of 1ms instead of 6ms as parameter indicated.
