issue on timing advance commands in lte

aquariuscottt

hi all


recently, i was studying on how timing advance is performed in lte system.. but i have a few questions ...so i come here to ask you guys..

(1) what is the minimum ta step size ? Is this setp size equal to all kinds of bandwidth, such as 1.4, 3, 5, 10, 15, 20 MHz

(2) how to estimate the delay corresponds to symbol timing in Nb RX?


Thanks in advance....
