Detailed Description

LTE eNB uplink scheduler with device-to-device (D2D) support. Extends the clean LteSchedulerEnbUl with the scheduling of D2D-mirror HARQ retransmissions and the D2D frequency-reuse (ALLOCATOR_BESTFIT) discipline. It is the LTE counterpart of ~NrSchedulerGnbUlD2D; keep the two in sync.

Member Function Documentation

◆ scheduleAdditionalRetransmissions()

unsigned int scheduleAdditionalRetransmissions ( GHz carrierFrequency,
BandLimitVector * bandLim = nullptr )
overrideprotectedvirtual

Schedules the D2D-mirror HARQ retransmissions (LTE synchronous HARQ variant: a single active acid per flow). Kept in sync with NrSchedulerGnbUlD2D::scheduleAdditionalRetransmissions() (asynchronous HARQ: iterates over all processes).

Reimplemented from LteSchedulerEnbUl.

◆ getScheduler()

LteScheduler * getScheduler ( SchedDiscipline discipline)
overrideprotected

The D2D uplink scheduler owns the ALLOCATOR_BESTFIT frequency-reuse discipline.
