Detailed Description

The HarqProcess struct.

The struct represent a single HARQ process, identified by an ID (unfortunately the ID is not stored in the struct, but somewhere else, as it will be explained later). The process has a status (HarqProcess::Status) and could be active or inactive. Inside the process is stored a shared pointer to a DciInfoElementTdma, which contains all the information for the retransmission of the data, as well as the RLC PDU.

The HarqProcess will be stored inside the class NrMacHarqVector, which is a unordered map that maps the HARQ ID with the HARQ content (this struct).

Member Enumeration Documentation

Status

enum ns3::HarqProcess::Status : uint8_t

Status of the process.

Other than the obvious meaning of the values, it is worth to state that the RECEIVED_FEEDBACK status is equivalent to "the process has received a NACK feedback". An ACKed feedback will be erased immediately (after all, it has been ACKed...). That is probably worth a name change.

Enumerator
INACTIVE	Inactive process.
WAITING_FEEDBACK	Data transmitted, waiting the feedback.
RECEIVED_FEEDBACK	Received feedback (NACK)
