LteAirFrame¶

Namespace: simu5g

packet LteAirFrame

Represents a physical layer transmission frame that encapsulates various types of messages/packets for transmission over the air interface, such as:

MAC PDUs (user data): transmitted as Transport Blocks (TB) on PDSCH/PUSCH
HARQ feedback: transmitted on PUCCH (uplink control channel)
Scheduling grants (DCI): transmitted on PDCCH (downlink control channel)
Random access and D2D packets: transmitted on respective control/data channels In the simulation, all these messages types are abstracted as LteAirFrame transmissions.
