Detailed Description
LTE eNB uplink scheduler.
Member Function Documentation
◆ checkEligibility()
|
overrideprotected |
Checks Harq Descriptors and returns the first free codeword.
- Parameters
-
id cw
- Returns
◆ scheduleAdditionalRetransmissions()
|
protectedvirtual |
Hook for scheduling additional (non-UL) retransmissions (e.g. D2D mirror HARQ), called by rtxschedule() after the UL retransmission handling. Returns the number of bytes allocated.
Reimplemented in LteSchedulerEnbUlD2D, and NrSchedulerGnbUlD2D.
◆ updateHarqDescs()
|
virtual |
Updates HARQ descriptor current process pointer (to be called every TTI by main loop).
Reimplemented in NrSchedulerGnbUl.
◆ racschedule()
|
override |
Updates current schedule list with RAC grant responses.
- Returns
- TRUE if OFDM space is exhausted.
◆ rtxschedule()
|
override |
Updates current schedule list with HARQ retransmissions.
- Returns
- TRUE if OFDM space is exhausted.
◆ signalRac()
|
inlinevirtual |
Schedule retransmissions for background UEs
- Returns
- TRUE if OFDM space is exhausted. signals RAC request to the scheduler (called by e/gNb)
References racStatus_.
◆ schedulePerAcidRtx()
|
override |
Schedules retransmission for the Harq Process of the given UE on a set of logical bands. Each band has also assigned a band limit amount of bytes: no more than the specified amount will be served on the given band for the acid.
- Parameters
-
nodeId The node ID carrierFrequency carrier frequency cw The codeword used to serve the acid process bands A vector of logical bands acid The ACID
- Returns
- The allocated bytes. 0 if retransmission was not possible
