`Interfaces to the physical layer

`The physical layer (layer 1) is the lowest layer in the OSI Reference Model and it supports all functions required for the
`transmission of bit streams on the physical medium.
`
`The physical layer interfaces the Medium Access Control (MAC) Layer and the Radio Resource Control (RRC) Layer
`as depicted in figure 1.

`Interface to MAC
`4.1
`The physical layer interfaces the MAC entity of layer 2. Communication between the Physical Layer and MAC is in an
`abstract way performed by means of PHY-primitives defined which do not constrain implementations.
`
`NOTE: The terms physical layer and layer 1, will be used synonymously in this description.
`
`The PHY-primitives exchanged between the physical layer and the data link layer provide the following functions:
`
`-
`
`-
`
`transfer of transport blocks over the radio interface;
`
`indicate the status of the layer 1 to layer 2.
`
`Interface to RRC
`4.2
`The physical layer interfaces the RRC entity of layer 3 in the UE and in the network.
`
`Communication is performed in an abstract way by means of CPHY-primitives. They do not constrain implementations.
`
`The CPHY-primitives exchanged between the physical layer and the Network layer provide the following function:
`
`- control of the configuration of the physical layer.
`
`The currently identified exchange of information across that interface has only a local significance to the UE or
`Network.

`
`Services and functions of the physical layer
`
`General
`5.1
`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. The characteristics of a transport channel are defined by its transport format
`(or format set), specifying the physical layer processing to be applied to the transport channel in question, such as
`convolutional channel coding and interleaving, and any service-specific rate matching as needed.
`
`The physical layer operates exactly according to the L1 radio frame timing. A transport block is defined as the data
`accepted by the physical layer to be jointly encoded. The transmission block timing is then tied exactly to this L1 frame
`timing, e.g. every transmission block is generated precisely every 10ms, or a multiple of 10 ms.
`
`A UE can set up multiple transport channels simultaneously, each having own transport characteristics (e.g. offering
`different error correction capability). Each transport channel can be used for information stream transfer of one radio
`bearer or for layer 2 and higher layer signalling messages.
`
`The multiplexing of these transport channels onto the same or different physical channels is carried out by L1. In
`addition, the Transport Format Combination Indication field (TFCI) shall uniquely identify the transport format used by
`each transport channel of the Co
