Improve radio for Metanoia RU (and likely others) We introduced a regression that lowered the achievable DL throughput with at least the Metanoia RU (i.e., in the configuration and the UE that we use). git bisect showed up one commit, which does not seem necessary. We just revert this commit, as it improves the throughput and does not seem to have a negative impact on performance. Further, increase RLC buffers a bit. Limit 7.2 pipeline number of layers to 2.
Configuration files: naming style guide
The configuration files should have the following name format:
<type>[.<sa|nsa>][.band<num>.[u<num>.]<num>prb].<sdr>[.<opt>].conf
Where:
[]means this field is optional<type>: one ofgnb,enb,gnb-cu,gnb-du,nrue,lteue, etc.<sa|nsa>: in the case of 5G, notes whether this is SA or NSA<num>forband/u/prb: numerical value. Note that band/PRB are only applicable in some cases. The numerologyuis only to be set for 5G if it differs fromu1.<sdr>: what SDR board/split this is tailored for:- e.g.,
usrpb210,usrpn310,rfsim,aw2s - if there is no SDR (e.g., for a CU), use the south-bound split, e.g.,
f1,if4p5, etc. - for the L2simulator, write
l2sim
- e.g.,
<opt>: optional specifiers. If there are multiple, concatenated using a dash (-). Examples:2x2prs(positioning reference signal)ddsuu(specific TDD pattern)tm2: Transmission Mode 2 in 4Goaiue: specifies usage with OAI UE and not COTS UE
Examples:
- standard monolithic gNB, 2x2 configuration, with SDAP:
gnb.sa.band78.162prb.usrpn310.2x2-sdap.conf - gNB-CU:
gnb-cu.sa.f1.conf - monolithic gNB, L2sim:
gnb.sa.band77.106prb.l2sim.conf - monolithic eNB:
enb.band7.25prb.usrpb200.conf - RCC (4G eNB with IF4.5 split):
enb-rcc.band7.25prb.tm1.if4p5.conf
Notes:
- there is no need for TDD/FDD, this is encoded in the band number
- there is no need for FR1/FR2, this is encoded in the band number
