Detailed Description

Default algorithm for assigning offset and periodicity.

The algorithm assign the same periodicity to all the UEs. When a new periodicity is asked, it is returned a value between 1 and the configured periodicity (minus 1).

The returned values will never be the same; instead, when this must happen, an invalid value is returned and (hopefully) an increase of periodicity is invoked.

Introspection did not find any typical Config paths.

◆ AddUe()

NrMacSchedulerSrs::SrsPeriodicityAndOffset ns3::NrMacSchedulerSrsDefault::AddUe ( )

overridevirtual

Function called when the scheduler needs to know what is the offset and periodicy of a newly added ue.

Returns: a struct that contains the periodicity and the offset. If the struct is not valid, an increase in periodicity is probably needed.

◆ AssignStreams()

int64_t ns3::NrMacSchedulerSrsDefault::AssignStreams ( int64_t stream )

Assign a fixed random variable stream number to the random variables used by this model. Return the number of streams (possibly zero) that have been assigned.

Parameters

stream first stream index to use
