11bit RACH support in osmo-bts-trx
osmo-bts-trx currently can only do 8bit RACH, unlike other BTS models
- Status changed from Stalled to In Progress
- % Done changed from 10 to 40
After merging https://gerrit.osmocom.org/c/osmo-bts/+/6315 and corresponding https://gerrit.osmocom.org/c/osmo-trx/+/11423 and related OsmoTRX patches there's TTCN-3 failure in TC_rach_content() and TC_rach_count() due to some (about 16 out of 1000) RACH being "lost". So far I'm unable to reproduce this using real phone. I'm not sure yet what's so special about the lost RACH (e. g. '0xCF') which makes a difference or whether rach content itself has anything to do with it at all. Investigation is ongoing.
