Detailed Description

QoS-aware proportional-fair scheduler: scores active CIDs with QoS weights derived from the per-DRB QoS profile. The weight reads the GBR flag, the packet delay budget and the priority level; the profile's packet error rate reaches the scheduler and is carried through a group's aggregate, but does not enter the weight. The profiles come from the MAC's DRB QoS map (see LteMacEnb::getDrbQosMap()), which RRC fills from the bearer configuration delivered to it (the staticDrbs parameter of the ~BearerConfigurator module).

A CID whose bearer has no QoS profile is scheduled with a neutral weight (plain proportional fair).

◆ collectUlGroupMembers()

std::vector< const DrbQosProfile * > collectUlGroupMembers	(	const std::map< DrbKey, DrbQosProfile > &	drbQosMap,
		LteMacBase *	mac,
		MacNodeId	ueId,
		Lcg	lcg )

static

The QoS profiles of the DRBs behind one uplink logical channel group: the join of the MAC's configured-DRB profiles with its established channels' group assignment. A configured-but-unestablished DRB has no channel config yet and is skipped, so the result is empty when no established DRB of the UE belongs to the group.

◆ aggregateQosProfiles()

DrbQosProfile aggregateQosProfiles ( const std::vector< const DrbQosProfile * > & members )
