faluco e0238f4092 NR: Fix a race condition where we could remove a UE from the mac while still being accessed by the NR PHY worker. 2021-10-06 11:31:54 +02:00
faluco a703279975 Fix a data race when passing the nr_workers to the txrx worker. 
There was an unprotected access of the txrx reading this variable while being set from a different thread.
Fix it by starting the txrx thread after all variables are ready.

Andre Puschmann 06fbb58d70 gnb,mac: add dedicated arguments struct for MAC-NR 
as the PCAP object is now only visible inside MAC-NR we can't
share the PCAP file between EUTRA/NR (like we do in the UE).

This patch removes the hard-coded filename for the NR PCAP file.

Carlo Galiotto bc7c21b8c3 sched,nr: add test case for SSB scheduling 
The SSB test checks whether, with the given periodicity, the
SSB grant is present within the dl_sched structure passed to the PHY.
It also checks that the SSB grant is not scheduled outside
the required time slots.

NOTE: The test is a modified version of an existing scheduler test.

Carlo Galiotto fd4b368f71 sched,nr: handle case of ssb_periodicity not given 
If the parameter ssb_periodicity is not given by higher layers,
the function needs to handle this case. The parameters could be
passed with 0 value, which makes the function crash.

For the time being, if ssb_periodicity is not given, the std value
5 ms will be used.
