+# 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 of `gnb`, `enb`, `gnb-cu`, `gnb-du`, `nrue`, `lteue`, etc.
+- `<sa|nsa>`: in the case of 5G, notes whether this is SA or NSA
+- `<num>` for `band`/`u`/`prb`: numerical value. Note that band/PRB are only
+  applicable in some cases. The numerology `u` is only to be set for 5G if it
+  differs from `u1`.
+- `<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`
+- `<opt>`: optional specifiers. If there are multiple, concatenated
+  using a dash (`-`). Examples:
+  * `2x2`
+  * `prs` (positioning reference signal)
+  * `ddsuu` (specific TDD pattern)
+  * `tm2`: Transmission Mode 2 in 4G
+  * `oaiue`: 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`
+- RCC (4G eNB with IF4.5 split): `enb.band40.25prb.if45.tm1-fairscheduler.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
