2020-09-22osmo-bts-trx/scheduler: refactor UL burst measurement processingVadim Yanitskiy1-10/+28
Currently the UL measurements (RSSI, ToA256, C/I) of the burst that concludes a block are passed up to the higher layers. This means that the measurement values of the other bursts are skipped. Let's keep record of all UL measurements and average the values before we pass them up to the higher layers. Use a simple ring buffer to store the measurement history (up to 8 unique entries for now). Remove *_num/*_sum variables from l1sched_chan_state.

2020-09-17gsm_data: rename hopping.{ma,ma_len} to hopping.arfcn_{list,num}Vadim Yanitskiy1-2/+2
MA (Mobile Allocation) is actually a bit-mask indicating those ARFCNs of the Cell Allocation, which must be used as the hopping sequence. What we store in struct gsm_bts_trx_ts is the actual list of hopping channels, so let's name it properly and eliminate possible confusion. Change-Id: I677d66e428fa0fe119ebc37bc2a4e6cc05c251c4

2020-09-15Fix RadioCarrier OML Operative State Change report not sent on some scenariosPau Espin Pedrol1-1/+1
Operative state is mainly maintained based on 2 requirements: * phy_link being in CONNECTED state * RSL connection being up and ready However, state change report triggered over OMl towards BSC was only done upon the first event of the two. That means that if for whatever reason the RSL connection was established AFTER the phy_link became CONNECTED (ie receiving RSP POWERON in osmo-bts-trx), then the status towards the BSC would not be updated and hence the BSC would still see the Radio Carrier object as DISABLED. The trx_set_available() function is renamed to trx_operability_update() to keep the logic conditions in one place, and different events triggering a change in state simply call the function and let it handle the new state.

2020-08-07osmo-bts-trx/scheduler: implement baseband frequency hoppingVadim Yanitskiy2-0/+4
The idea behind the baseband frequency hopping is quite simple: we have several RF carriers (transceivers) transmitting and receiving on fixed frequencies (just like in a regular multi-trx setup), and an additional burst routing layer between the schedulear and the transceiver interface (TRXD over UDP). Speaking in terms of the proposed implementation: - on Downlink, dlfh_route_br() calculates the ARFCN corresponding to the current TDMA frame number according to the hopping sequence parametets, and picks the transceiver with matching ARFCN; - on Uplink, ulfh_route_bi() iterates over the transceiver list of of the BTS, calculating hopping ARFCNs for equivalent timeslots, and picks the one with ARFCN matching the received burst. In order to avoid frequent transceiver lookups on the Downlink path, dlfh_route_br() maintains a "cache" in the timeslot state structure. Unfortunately, this "cache" seems to be useless on the Uplink path, so ulfh_route_bi() always needs to lookup the matching transceiver for each burst received over the TRXD interface. It may also happen that the scheduler will be unable to route an Uplink or Downlink burst, e.g. due to inconsistent / incorrect hopping sequence parameters received from the BSC, or in case if a transceiver gets RF-locked by the BTS operator. Such events are logged as "FATAL" and aditionally signalled by the following osmo-bts-trx specific rate counters: - trx_sched:dl_fh_no_carrier (Downlink), and - trx_sched:ul_fh_no_carrier (Uplink).

2020-08-04osmo-bts-trx/scheduler: refactor dummy burst schedulingVadim Yanitskiy1-0/+1
This change facilitates the upcoming freq. hopping implementation, in particular scheduling of dummy bursts on C0 with hopping time- slots. One problem is that we cannot know in advance, whether to send a dummy burst on a given timeslot unless all transceivers are processed. For example, trx#3 may want to send a normal burst on ARFCN of trx#0 (C0), while we have already sent a dummy burst... Another important aspect is that we shall not be sending dummy bursts on transceivers other than C0. Scheduling dummy bursts from _sched_dl_burst() in the context of a single hopping timeslot of a single transceiver leaves trx_sched_fn() no way to know whether it's a dummy burst or something else. Let's solve both problems by moving dummy burst scheduling logic from _sched_dl_burst() to trx_sched_fn(). Maintain C0 slot-mask in the inner (per-trx) loop, so that we can fill missing bursts with dummy bursts afterwards. Change-Id: I8c3651c27d2991079e83b8abdb7e2c3f95b97a43 Related: SYS#4868, OS#4546

According to 3GPP 45.002, section 5.2.4, a frequency correction burst is basically a sequence of zeros. Since br->burst is already zero-initialized, there is no need to maintain and memcpy() another sequence of zeros into it. Just set the length. Change-Id: Ic4f6d550010da5caf4bc471ff1e184c9fab30c6d

2020-06-23bts_shutdown: Wait until all TRX are closedPau Espin Pedrol1-0/+2
Setting the phy link of a trx to SHUTDOWN sets operative state to DISABLED, so we use operative state as a condition to know whether all TRX are already powered off properly and we can exit. Change-Id: I2bcd211d7edcc8486461a555d6c470a94b166ed7
2020-06-23bts_model: Convert bts_model_trx_close() to return asynchronouslyPau Espin Pedrol1-1/+9
Some backends like osmo-bts-trx require exchanging messages like POWEROFF to close the TRX, and hence need some time. Switch the function to expect result asynchronously by calling a callback. This will be used later to wait until all TRX are really powered off before exiting the process. Change-Id: I7d76b600fc06e1114b35bf0c2d08eff5bbd1b69a

2020-06-15A-bis/RSL: refactor handling of BS Power IE (power reduction)Vadim Yanitskiy2-7/+6
According to 3GPP TS 08.58, section 9.3.4, BS Power IE indicates the transmission power attenuation on a particular channel: +--------------+---------+-----------------+ | Reserved (3) | FPC (1) | Power level (4) | +--------------+---------+-----------------+ so let's change handling of this IE as follows: - s/bs_power/bs_power_red/g, so it reflects 'reduction'; - store power attenuation value in dB, not in 2 db steps; - get rid of ms_power_ctrl.bts_tx_pwr, it's always 0 anyway; - fix rsl_tx_meas_res(): use lchan->bs_power_red; - always check if FPC (Fast Power Control) flag is set; - we don't support it, so reject messages containing it; - fix rsl_rx_chan_activ(): properly apply the bitmask.

This change simplifies access to generic logical channel state (struct gsm_lchan) from osmo-bts-trx specific state (struct l1sched_chan_state), so there is no need to look it up using get_lchan_by_chan_nr() on receipt of each Uplink burst. Change-Id: Ic4378020f980845b962f71b9e4b7faea738bc174
2020-06-15osmo-bts-trx: introduce and use struct trx_dl_burst_reqVadim Yanitskiy2-19/+29
This change is similar to what we did for Uplink bursts: - group all Downlink burst parameters into a single structure, - allocate it once and pass a pointer to lchan handlers, - pass a pointer to trx_if_send_burst(). Given that the structure is allocated and (zero-)initialized in trx_sched_fn(), we can get rid of some memset() calls in lchan handlers and thus improve the overall performance a bit.
