Yes, that is expected behavior. There will be power output as long as the slot is enabled. Right now the only way to turn off transmission is to disable the slot. -TT
hi thomas,
in case of TRX 0, osmo-bts always sends bursts, even on idle bursts. it sends dummy bursts in this case. i suggest that there is no RF power in case of TRX>0 for each single burst, that is not sent from osmo-bts. the reasons are:
- one TCH/H channel of one TS may be in use, so the other channel should be disabled, to reduce noise on the spectrum. - DRX (in the future) might be used to reduce noise on the spectrum. - SACCH is disabled when leaving dedicated mode, so the MS runs into radio link timeout, if the release message does not go through or some error occurs.
i think about three solutions to make make osmo-trx send no RF power per burst:
1. omso-bts does not send any burst to osmo-trx 2. sends a dummy burst with lowest possible power indication (pwr=255) 3. sends a burst with zero length data (only the 6 bytes header)
i prefer the first solution.
best regards,
andreas
