fixeria gerrit-no-reply at lists.osmocom.orgHello pespin, ipse, laforge, Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bts/+/14686 to look at the new patch set (#6). Change subject: Clarify and refactor link quality (C/I) handling ...................................................................... Clarify and refactor link quality (C/I) handling The radio link quality is defined by C/I (Carrier-to-Interference ratio), which is computed from the training sequence of each received burst, by comparing the "ideal" training sequence with the actual (received) one. Link quality measurements are used by L1SAP to filter out "ghost" Access Bursts, and by the link quality adaptation algorithms. One can define minimum link quality values using the VTY interface. On the VTY interface we expect integer C/I values in centiBels (cB, 10e-2 B), while the internal structures are using float values in deciBels (dB, 10e-1 B). Some PHYs (sysmo, octphy, oc2g, and litecell15) expose C/I measurements in deciBels, while on the L1SAP interface we finally send then in centiBels. Let's avoid this confusion and stick to a single format, that will be used by the internal logic of OsmoBTS - integer values (int16_t) in centiBels. This will give us the range of: -32768 .. 32767 centiBels, or -3276.8 .. 3276.7 deciBels, which is certainly sufficient.
