pespin gerrit-no-reply at lists.osmocom.orgpespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-gsm-tester/+/18637 ) Change subject: enb,ms: refactor base_rate selection for ZMQ ...................................................................... enb,ms: refactor base_rate selection for ZMQ Use tailored sample rate only use for 6, 50 and 75 PRB. For all other bandwidths, we use the full LTE rate and downsample. With 5.76e6 as base sample rate, for example, we had some issue during the tests like: [zmq] Error: tx time is 0.178 ms in the past (7833600 < 7835648) [zmq] Error: tx time is 0.011 ms in the past (7835520 < 7835648) Using a higher sample rate seems to work better.
