Harald Welte gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/6871
to look at the new patch set (#2).
measurement.c: Fix sdcch4_meas_rep_fn102 / sdcch8_meas_rep_fn102
Since Change-Id: I23fba50f48415314da40cf5bf86fce2ed3e66af6 we were not
reporting measurements for SDCCH channel types due to the wrong
encoding of the sdcch{4,8}_meas_rep_fn102 table.
Let's fix the table by encoding the needed information:
"What is the modulo-102 remainder of the first burst of the last block
before fn%102 reaches 37?" (SDCCH/4)
"What is the modulo-102 remainder of the first burst of the last block
before fn%102 reaches 12?" (SDCCH/8)
The TS 45.002 Clause 7 tables have to be consulted carefully to
determine this information.
Change-Id: Icf02354872670126ab3297b787b216981ca6c309
