4.1 Relation to other layers
4.1.1 General protocol architecture

The radio interface described in this specification covers the interface between the User Equipment (UE) and the

network, and sidelink transmissions between UEs. The radio interface is composed of the Layer 1, 2 and 3. The TS

36.200 series describes the Layer 1 (Physical Layer) specifications. Layers 2 and 3 are described in the 36.300 series.

Layer 1
Figure 1: Radio interface protocol architecture around the physical layer

Figure 1 shows the E-UTRA radio interface protocol architecture around the physical layer (Layer 1). The physical

layer interfaces the Medium Access Control (MAC) sub-layer of Layer 2 and the Radio Resource Control (RRC) Layer

of Layer 3. The circles between different layer/sub-layers indicate Service Access Points (SAPs). The physical layer

offers a transport channel to MAC. The transport channel is characterized by how the information is transferred over the

radio interface. MAC offers different logical channels to the Radio Link Control (RLC) sub-layer of Layer 2. A logical

channel is characterized by the type of information transferred.
4.1.2 Service provided to higher layers

The physical layer offers data transport services to higher layers. The access to these services is through the use of a

transport channel via the MAC sub-layer. The physical layer is expected to perform the following functions in order to

provide the data transport service:
- Error detection on the transport channel and indication to higher layers
- FEC encoding/decoding of the transport channel
- Hybrid ARQ soft-combining
- Rate matching of the coded transport channel to physical channels
- Mapping of the coded transport channel onto physical channels
- Power weighting of physical channels
- Modulation and demodulation of physical channels
- Frequency and time synchronisation

4.2 General description of Layer 1
4.2.1 Multiple access

The multiple access scheme for the LTE physical layer is based on Orthogonal Frequency Division Multiplexing

(OFDM) with a cyclic prefix (CP) in the downlink, and on Single-Carrier Frequency Division Multiple Access (SC-

FDMA) with a cyclic prefix in the uplink and sidelink. To support transmission in paired and unpaired spectrum, two

duplex modes are supported: Frequency Division Duplex (FDD), supporting full duplex and half duplex operation, and

Time Division Duplex (TDD).

The Layer 1 is defined in a bandwidth agnostic way based on resource blocks, allowing the LTE Layer 1 to adapt to

various spectrum allocations. A resource block spans either 12 sub-carriers with a sub-carrier bandwidth of 15kHz or 24

sub-carriers with a sub-carrier bandwidth of 7.5kHz each over a slot duration of 0.5ms, or 144 sub-carriers with a sub-

carrier bandwidth of 1.25kHz over a slot duration of 1ms. Narrowband operation is also defined, whereby certain UEs

may operate using a maximum transmission and reception bandwidth of 6 contiguous resource blocks within the total

system bandwidth; for narrowband operation, sub-resource-block operation may also be used in the uplink, using 2, 3 or

...
