Detailed Description
What a D2D UM TX entity offers the D2D mode controller.
The LTE (FI) and the NR (SO) profiles are separate class hierarchies, so a D2D-capable TX entity exists in two unrelated concrete flavours (~LteRlcUmTxEntityD2D, ~NrRlcUmTxEntityD2D). ~D2DModeController has to hold both in one registry, hence this narrow cross-technology interface – the same idiom as ID2dMacEnb/ID2dMacUe/ID2dAmc elsewhere in this package.
Discovery is by dynamic_cast from the RLC TX entity base.
Member Function Documentation
◆ resumeDownstreamInPackets()
|
pure virtual |
Release the SDUs parked in the holding buffer into the TX buffer, and resume normal downstream buffering. Called on the entity of the newly selected mode once the old-mode entity has drained.
Implemented in RlcUmTxEntityD2D< Base >, RlcUmTxEntityD2D< LteRlcUmTxEntity >, and RlcUmTxEntityD2D< NrRlcUmTxEntity >.
◆ isEmptyingBuffer()
|
pure virtual |
True while this entity is draining its TX buffer for a mode switch, i.e. the peer's new-mode entity must keep holding its incoming SDUs.
Implemented in RlcUmTxEntityD2D< Base >, RlcUmTxEntityD2D< LteRlcUmTxEntity >, and RlcUmTxEntityD2D< NrRlcUmTxEntity >.
◆ startHoldingDownstreamInPackets()
|
pure virtual |
Start parking incoming SDUs instead of buffering them. Used when a peer's old-mode entity is found to be still draining at registration time.
Implemented in RlcUmTxEntityD2D< Base >, RlcUmTxEntityD2D< LteRlcUmTxEntity >, and RlcUmTxEntityD2D< NrRlcUmTxEntity >.
◆ isHoldingDownstreamInPackets()
|
pure virtual |
True while incoming SDUs are being parked in the holding buffer.
Implemented in RlcUmTxEntityD2D< Base >, RlcUmTxEntityD2D< LteRlcUmTxEntity >, and RlcUmTxEntityD2D< NrRlcUmTxEntity >.
◆ rlcHandleD2DModeSwitch()
|
pure virtual |
Adapt the TX buffers and the sequence numbering to a D2D mode switch. Called by ~RlcMuxD2D on the entities of the old and the new mode.
Implemented in RlcUmTxEntityD2D< Base >, RlcUmTxEntityD2D< LteRlcUmTxEntity >, and RlcUmTxEntityD2D< NrRlcUmTxEntity >.
