◆ AssignBytesToDlLC()

std::vector< NrMacSchedulerLcAlgorithm::Assignation > ns3::NrMacSchedulerLcQos::AssignBytesToDlLC	(	const std::unordered_map< uint8_t, LCGPtr > &	ueLCG,
		uint32_t	tbs,
		Time	slotPeriod
	)		const

overridevirtual

Method to decide how to distribute the assigned bytes to the different LCs for the DL direction. This algorithm is based on the resource type and the guaranteed bitrate information of an LC. In particular, the operation is divided in 4 parts:

The first part creates two lists, one with the GBR/DC-GBR active LCs that have their ERAB guaranteed bit rate requirements set and one with all the active LCs.
In case there more than 1 GBR/DC-GBR active LCs that have their ERAB guaranteed bit rate requirements set, and their total requirements exceed the assigned bytes (tbs), then the algorithm assigns equally all the assigned bytes in RR fashion to these GBR/DC-GBR LCs.
In case their total requirements are less than the assigned bytes, the algorithm assigns to each LC the minimum among the ERAB guaranteed bit rate and the RLC buffer size.
The rest of the bytes, if any, are assigned in the rest of the LCs in RR fashion.

Parameters

ueLCG	LCG of an UE
tbs	TBS to divide between the LCG/LC

Returns: A vector of Assignation

Implements ns3::NrMacSchedulerLcAlgorithm.

Definition at line 40 of file nr-mac-scheduler-lc-qos.cc.

◆ AssignBytesToUlLC()

std::vector< NrMacSchedulerLcAlgorithm::Assignation > ns3::NrMacSchedulerLcQos::AssignBytesToUlLC	(	const std::unordered_map< uint8_t, LCGPtr > &	ueLCG,
		uint32_t	tbs
	)		const

overridevirtual

Method to decide how to distribute the assigned bytes to the different LCs for the UL direction. Due to the scheduler limitation the applied algorithm distributes bytes in a RR fashion (see NrMacSchedulerLcAlgorithm).

Parameters

ueLCG	LCG of an UE
tbs	TBS to divide between the LCG/LC

Returns: A vector of Assignation

Implements ns3::NrMacSchedulerLcAlgorithm.
