//
// Interface for the Physical (PHY) layer of the LTE/NR protocol stack.
//
// The PHY layer sends and receives MAC Protocol Data Units (SDUs) from the Medium Access Control (MAC)
// layer and transmits and receives frames over the radio medium. The PHY layer is responsible for handling
// the transmission and reception of radio frames, including measuring the Signal to
// Interference-plus-Noise Ratio (SINR) of received frames and determining whether they were received
// correctly or not. This is accomplished by utilizing an abstraction of the channel model without modeling
// the transmission and reception of individual symbols. Specifically, on the transmitting side, radio frames
// are sent directly to the intended receiver (via the sendDirect() method). On the receiving side, the
// ChannelModel class is used to obtain the SINR resulting from channel effects (such as path loss,
// fading/shadowing), as well as inter-cell interference, and to check the correctness of the reception using
// Block Error Rate (BLER) curves.
// The PHY layer also measures the uplink and downlink channel quality by computing Channel Status
// Information (CSI) for User Equipments (UEs) in both uplink and downlink directions.
// Handover management is also the responsibility of the PHY layer.
