dexter gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, laforge, fixeria, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bts/+/21329 to look at the new patch set (#3). Change subject: sched_lchan_tchh: fix frame number and fill FACCH gap ...................................................................... sched_lchan_tchh: fix frame number and fill FACCH gap The measurement results / TCH indications that are handed when decoding the TCH/H are off by two bursts. Since a measurement result / TCH block is expected every two bursts anyway the problem can only be noticed when a FACCH transmission is going on and the frame numbers of the BFI TCH blocks appear to be missaligned towards the FACCH block. The reason is that the incoming bursts are shifted into a 6 burst wide buffer. The decoding functions always look at the beginning of that buffer while the bursts are shifted into the buffer from the end. A facch will always fit exactly in that buffer but TCH/H blocks are only 4 bursts wide and thereofre they need two additional bursts until they reach the coverage of the decoding function. Lets fix this by putting the correct frame number (from two bursts before) into the remap functions in order to get the correct beginning of the block. Since the FACCH transmission uses six blocks it takes out two TCH blocks. This means that if we count the FACCH block we end up with a gap of one TCH voice block. Lets generate a dummy measurement to compensate the gap. This will also match the behavior of the osmo-bts-sysmo phy.
