Detailed Description

SAP interface between the MAC and the PHY.

The API between the MAC and the PHY classes, for UE and GNB, is defined in this class. The direction is from the MAC to the PHY (i.e., the MAC will have a pointer of this class, that points to a valid instance of the PHY).

As a general rule, no caching is allowed for the values returned by any Get* method, because those values can change dynamically.

Member Function Documentation

GetBeamId()

virtual BeamId ns3::NrPhySapProvider::GetBeamId ( uint8_t  rnti ) const

pure virtual

Get the beam ID from the RNTI specified. Not in any standard.

Parameters

rnti	RNTI of the user

Returns

Beam ID of the user

The MAC asks for the BeamId of the specified used.

Referenced by ns3::NrGnbMac::DoSlotDlIndication().

Here is the caller graph for this function:

GetBwpId()

virtual uint16_t ns3::NrPhySapProvider::GetBwpId ( ) const

pure virtual

Retrieve the bandwidth part id.

Returns

The Bwp id of the PHY

Referenced by ns3::NrGnbMac::GetBwpId(), and ns3::NrUeMac::GetBwpId().

Here is the caller graph for this function:

GetCellId()

virtual uint16_t ns3::NrPhySapProvider::GetCellId ( ) const

pure virtual

Retrieve the cell id.

Returns

The cell id of the PHY

Referenced by ns3::NrGnbMac::GetCellId(), and ns3::NrUeMac::GetCellId().

Here is the caller graph for this function:

GetRbNum()

virtual uint32_t ns3::NrPhySapProvider::GetRbNum ( ) const

pure virtual

Retrieve the number of resource blocks.

Returns

Get the number of resource blocks configured

Referenced by ns3::NrGnbMac::GetDlCtrlDci().

Here is the caller graph for this function:

GetSlotPeriod()

virtual Time ns3::NrPhySapProvider::GetSlotPeriod ( ) const

pure virtual

Retrieve the slot period.

Returns

the slot period (don't store the value as it depends on the numerology)

GetSpectrumModel()

virtual Ptr< const SpectrumModel > ns3::NrPhySapProvider::GetSpectrumModel ( )

pure virtual

Retrieve the spectrum model used by the PHY layer.

Returns

the SpectrumModel

It is used to calculate the CQI. In the future, this method may be removed if the CQI calculation is done in the PHY layer, just reporting to MAC its value.

GetSymbolsPerSlot()

virtual uint32_t ns3::NrPhySapProvider::GetSymbolsPerSlot ( ) const

pure virtual

Retrieve the number of symbols in one slot.

Returns

the number of symbols in one slot (it is an attribute in the PHY, so it can be changed dynamically – don't store the value)

SendControlMessage()

virtual void ns3::NrPhySapProvider::SendControlMessage ( Ptr< NrControlMessage >  msg )

pure virtual

Send a control message.

Parameters

msg	the message to send

The MAC sends to the PHY a control message. The PHY will take care of considering the MAC-TO-PHY delay.

SendMacPdu()

virtual void ns3::NrPhySapProvider::SendMacPdu ( const Ptr< Packet > &  p, const SfnSf &  sfn, uint8_t  symStart, uint16_t  rnti  )

pure virtual

Send a Mac PDU.

Parameters

p	PDU
sfn	SFN
symStart	symbol inside the SFN
rnti	the RNTI of the receiving or transmitting UE, to map PDU to each UE's PHY signal

The MAC sends to the PHY a MAC PDU, represented by the packet p. The PDU MUST have a NrRadioBearerTag and a NrMacPduHeader.

SendRachPreamble()

virtual void ns3::NrPhySapProvider::SendRachPreamble ( uint8_t  PreambleId, uint8_t  Rnti  )

pure virtual

Send the RACH preamble.

Parameters

PreambleId	the ID of the preamble
Rnti	the RNTI

SetSlotAllocInfo()

virtual void ns3::NrPhySapProvider::SetSlotAllocInfo ( const SlotAllocInfo &  slotAllocInfo )

pure virtual

Set a SlotAllocInfo inside the PHY allocations.

Parameters

slotAllocInfo

the allocation

Called by the MAC to install in the PHY the allocation that has been prepared.
