Detailed Description

UE-side logical channel prioritization (LCP): divides one TTI's UL grant among the UE's outgoing connections, at the granularity Simu5G models – the logical channel group stands in for the per-channel priority of TS 36.321/38.321 sec 5.4.3.1. Groups are served in increasing LCG-index order (strict priority; the PBR token bucket, the full LCP's protection of lower priorities, is not modeled). Within a group the backlogged connections are served round-robin, one SDU (LTE FI) or one PDU carve (NR SO) per turn, so equal-priority connections are served equally and a connection's share does not depend on where bearer-establishment order placed it in the registration map.

◆ CidList

typedef std::list<MacCid> CidList

LcgScheduler ( LteMacUe * mac)

Default constructor.

◆ ~LcgScheduler()

virtual ~LcgScheduler ( )

Destructor.

Member Function Documentation

◆ setUeUlScheduler()

virtual void setUeUlScheduler ( LteSchedulerUeUl * ueScheduler)
inlinevirtual

Initializes the LteScheduler.

Parameters
ueSchedulerUE scheduler

◆ checkForPendingAdditionalBsr()

virtual bool checkForPendingAdditionalBsr ( Direction grantDir,
Lcg lcg )
inlineprotectedvirtual

Hook, called once per LCG during schedule(): returns true if the current UL grant must be withheld so that it can carry the BSR of an active D2D connection instead. Default implementation never withholds (no-op); overridden by LcgSchedulerD2D.

Reimplemented in LcgSchedulerD2D.
