time_adv_nsamples: is static TA value for the ue once this parameter is set in the ue.conf file?

Issue Description

I have a question more than an issue. When setting the timing_adv_nsamples value am I setting a static time length in number of radio samples that the ue will always use for timing advance or am I defining one timing advance unit time duration in number of radio samples?

Setup Details

USRP B210 as UE. So, when the ue receives the TA command inside of the DL RAR message, is the ue using multiples of the 100 samples default setting to advance future UL traffic (ie if TA is commanded by the eNB to 2, does the UE use 200 samples as its timing advance)? Or, does the ue always use the 100 samples time length as its timing advance regardless of the TA commanded in the DL RAR?
