Andre Puschmann c8d6f54dab enb,rrc: add radio link monitoring config 3 years ago
Francisco 400d7587c8 lte,rrc,enb: stop rlf timers after the UE performs intra-eNB handover 
The RLF timers may be triggered before handover, which will lead to the
UE getting released after it successfully handovers. To avoid this,
we should stop the timers.

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.
