Detailed Description

A container of received TBTPs.

All the received TBTPs with the calculated transmit time are stored here. The container may be used to check whether the UT has known scheduled time slots in the future.

Returns: the object TypeId

References m_maxStoredTbtps.

◆ HasScheduledTimeSlots()

bool ns3::SatTbtpContainer::HasScheduledTimeSlots ( )

Method of checking whether the UT has been scheduled time slots into the future.

Returns: bool Boolean indicating whether UT has been scheduled time slots into the future.

The time slots are not necessarily in increasing order in the TBTP. Sort the time slots into increasing order based on time.

Calculate the duration of the last slot. To be able to do that we need the superframe conf, frame conf, time slot conf and symbol rate.

Check that the TBTP has a time slot which is in the future. It does not matter how long to the future the time slot is, since the same method may be used for both CRDSA and SA, and we do not have any idea of what are their randomization intervals etc.
