[M] Change in osmocom-bb[master]: fake_trx.py: remove SETSLOT based burst filtering

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmocom-bb/+/33165 ) Change subject: fake_trx.py: remove SETSLOT based burst filtering ...................................................................... fake_trx.py: remove SETSLOT based burst filtering For the sake of simplicity and due to some performance limitations, fake_trx.py does not generate TRXD NOPE indications for osmo-bts-trx on its own. It's actually trxcon sending NOPE.req (empty Tx PDUs) when it has nothing to send, and fake_trx.py simply converting them. In a follow-up change [1] we remove trxcon's internal clock module, making the Uplink burst scheduling being driven by Downlink bursts with the respective TDMA Fn/Tn values. Given that fake_trx.py is currently dropping bursts received for inactive timeslots, we would get NOPE.req only for a single timeslot, the one being currently active. This would break several testcases in ttcn3-bts-test. Remove SETSLOT based burst filtering, so that trxcon would still be able to generate NOPE.req for all, active and inactive timeslots. Downlink bursts for inactive timeslots are discarded anyway.

[L] Change in osmocom-bb[master]: trxcon: get rid of the timer driven clock module

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmocom-bb/+/32575 ) Change subject: trxcon: get rid of the timer driven clock module ...................................................................... trxcon: get rid of the timer driven clock module trxcon was heavily inspired by osmo-bts-trx, and among with many other scheduling related parts also inherited the timer driven clock module. This clock module is driving the Uplink burst scheduling, just like it does drive the Downlink burst scheduling in osmo-bts-trx. Just like in osmo-bts-trx, the clock module relies on periodic CLCK indications from the PHY, which are needed to compensate for the clock drifting. The key difference is that trxcon is using Downlink bursts as the CLCK indications, see 'bi.fn % 51' in trx_data_rx_cb(). This is possible because the MS is a clock slave of the BTS: the MS PHY needs to sync its freq. and clock first, and only after that it can Rx and Tx. So far we've had no problems with the clock module in trxcon until we started adding GPRS support and integrated the l1gprs. While the CS domain is quite flexible in terms of timings and delays, the PS domain is a lot more sensetive to the timing issues. Sometimes it happens that the trxcon's clock module is ticking quicker than it should, resulting in Uplink PDCH blocks being scheduled earlier than the respective Downlink PDCH blocks are received: 20230502021957724 l1sched_pull_burst(): PDTCH/U Tx time (fn=56103) 20230502021957744 (PDCH-7) Rx DL BLOCK.ind (fn=56103, len=23): ... 20230502021957747 l1sched_pull_burst(): PDTCH/U Tx time (fn=56108) 20230502021957765 l1sched_pull_burst(): PDTCH/U Tx time (fn=56112) 20230502021957767 (PDCH-7) Rx DL BLOCK.ind (fn=56108, len=23): ... 20230502021957768 (PDCH-7) Rx UL BLOCK.req (fn=56112, len=54): ... 20230502021957784 l1sched_pull_burst(): PDTCH/U Tx time (fn=56116) 20230502021957784 TS7-PDTCH dropping Tx primitive (current Fn=56116, prim Fn=56112) This is impossible in reality, because Uplink is intentionally lagging behind Downlink by 3 TDMA timeslot periods. In a virtual setup this causes sporadic dropping of Uplink PDCH blocks, as can be seen from the logging snippet above, and significantly degrades the RLC/MAC performance for GPRS. Let's remove the internal clock module and trigger the Uplink burst transmission each time we receive a Downlink burst. This helps to overcome the GPRS scheduling issues and replicates the approach of osmo-trx-ms more closely.

[S] Change in osmocom-bb[master]: trxcon: do not advance Uplink TDMA Fn by default

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmocom-bb/+/33166 ) Change subject: trxcon: do not advance Uplink TDMA Fn by default ...................................................................... trxcon: do not advance Uplink TDMA Fn by default The idea behind advancing Uplink TDMA Fn is to give the transceiver, which is usually a separate process, some additional time to receive and prepare Uplink bursts for transmission. This comes at a price of having an additional delay between Uplink and Downlink. Given that trxcon, as a standalone application, is primarily used in conjunction with fake_trx.py for running ttcn3-bts-test against osmo-bts-trx, there is no reason to advance the Uplink TDMA Fn.
