11bit RACH is actually being worked on, assigning this to aravind. It might even be complete for some BTS models by now.
#2 Updated by arvind.sirsikar almost 3 years ago
Currently it is supported and integration tested for NuRAN LC1.5 and LC1.0. However there is no support for osmo-trx.

Gerrit 5062 has been merged. Have to verify whether 11-bit RACH is supported on sysmoBTS.

Test with "gprs 11bit_rach_support_for_egprs" failed - seems like smth wasn't merged/missing. See related BTS bug.

The following patch should implement 11-bit RACH support of osmo-bts-trx:

Both osmo-trx and osmo-bts-trx do support 11-bit encoded Access Bursts now. We also have a TTCN-3 test case for that (see BTS_Tests.TC_pcu_ext_rach_content) and it passes. However, all my attempts to test the network with the real phones have been unsuccessful. Unfortunately, I have no time to investigate further now.
