Detailed Description

The base for all the TDMA schedulers.

An example of TDMA-based scheduling is the following:

(f)
^
|=|===|===|===|===|=|
|C| U | U | U | U |C|
|T| E | E | E | E |T|
|R|   |   |   |   |R|
|L| 1 | 2 | 3 | 4 |L|
|----------------------------> (t)

The UEs are scheduled by prioritizing the assignment of symbols: the entire available spectrum is assigned, for a number of symbols that depend on the LC byte requirements.

In order to construct a slot like the previous one, the class defines a general algorithm, based on top of NrMacSchedulerNs3, to know how many, and what, UEs to schedule. The NrMacSchedulerNs3::ScheduleDl function needs three information that should be provided by the subclasses, to answer the following three questions:

How distribute the symbols between beams?
How many RBG should be assigned to the each active UE?
How to place the blocks in the 2D plan (in other words, how to create the DCIs)?

The first two are answered by the methods AssignDLRBG() and AssignULRBG(). The choice of what UE should be scheduled, and their order, is demanded to the subclasses. For more information, please refer to the methods documentation.

Subclasses should also implement what actions should be done before any assignment (NrMacSchedulerTdma::BeforeDlSched and NrMacSchedulerTdma::BeforeUlSched) as well as what to do after a symbol has been assigned (for the UE that got that symbols, and the UE that did not).

The last one is answered by CreateDlDci() or CreateUlDci(), which call CreateDci() to perform the "hard" work.

NrMacSchedulerTdma::BeamSymbolMap ns3::NrMacSchedulerTdma::AssignDLRBG	(	uint32_t	symAvail,
		const ActiveUeMap &	activeDl
	)		const

overrideprotectedvirtual

Assign the available DL RBG to the UEs.

Parameters

symAvail	Number of available symbols
activeDl	active DL flows and UE

Returns: a map between the beam and the symbols assigned to each one

The function will prepare all the needed callbacks to return UE DL parameters (e.g., the DL TBS, the DL RBG) and then will call NrMacSchedulerTdma::AssignRBGTDMA.

virtual void ns3::NrMacSchedulerTdma::AssignedDlResources	(	const UePtrAndBufferReq &	ue,

protectedpure virtual

Update the UE representation after a symbol (DL) has been assigned to it.

Parameters

ue	UE to which a symbol has been assigned
assigned	the amount of resources assigned
totalAssigned	the amount of total resources assigned until now

After an UE is selected to be eligible for a symbol assignment, its representation should be updated. The subclasses, by implementing this method, update the representation by updating some custom values that reflect the assignment done. These values are the one that, hopefully, are checked by the comparison function returned by GetUeCompareDlFn().

Provide the comparison function to order the UE when scheduling DL.

Returns: a function that should order two UEs based on their priority: if UE a is less than UE b, it will have an higher priority.
