Sakthivel Velumani 7edb235102 Updating gnb config files 2021-04-26 22:47:19 +02:00
Thomas Schlichter b073ca48c3 gNB: improve TA accuracy 
The TA calculation takes the CIR peak position error and scales it according to 38.213 section 4.2.
Till now it was simply an integer division "timing_advance_update = sync_pos / bw_scaling".

E.g. in case of bandwidth_scaling == 16, the timing_advance_update was 0 for sync_pos between -15 and +15.
With this change, this range (and thus the UL timing error) will be reduced to -8 and +8.

Thomas Schlichter 5c6865fbc6 5G NR: simplify init_timeshift_rotation() 
Only Ncp1 is used, so get rid of the second timeshift_symbol_rotation array.
Also simplify the computation of "t0 * Tc * f".

Thomas Schlichter 942037beb3 5G NR: move CIR peak to 0 
The rotation compensating the shifted OFDM position _before_ the channel estimation makes the CIR peak move back to 0.
We have to take this into account on gNB side when calculating the timing advance command, and on UE side in the time adjustment.

Sakthivel Velumani 945a020f93 Added linear phase derotation in UL 
This is necessary to compensate the rotation caused by the timeshifted OFDM symbol (1/8 CP)

Thomas Schlichter 87b53883b2 HACK: cut PUSCH and PDSCH OFDM symbol after complete CP 
Currently we cute the PUSCH and PDSCH OFDM symbols starting within the last 1/8th of the CP to avoid ISI.
This time shift leads to a rotation in frequency domain.
The current PRB based channel estimation does not compensate for the rotation _within_ a PRB, leading to bad performance.

This commit should _not_ make it into develop branch, it is just for testing!
Instead, we should do some compensating rotation before channel estimation.

MR !1114 : sanitize v1
-bugs or dirty code fixed 
-add first version of a rf board calibration tool, not finished

MR !1094 : sim channels
Channel simulation: 
-command mode: to change noise, path loss, model (AWGN, RICE, ...) parameters channel simulation 
-channels separation: each channel can have a different model (for HO test for example) 
-a new build option --sanitize to compile all OAI with gcc --sanitize=address

MR !1034 : new gtpu
-New GTPU implementation

MR !1101 : develop-SA-CBRA
-Implementation of Contention Based Random Access procedures for 5G-NR Initial Access in SA mode (including contributions from BUPT and Fujitsu)
