4 Services and functions of the physical layer
4.1 General
The physical layer offers data transport services to higher layers.
The access to these services is through the use of transport channels via the MAC sub-layer.
A transport block is defined as the data delivered by MAC layer to the physical layer and vice versa.
4.2 Overview of L1 functions
As mentioned in [2, TS 38.201], the physical layer is expected to perform the following functions to provide the data
transport service:
