1 Scope
The present document defines the service offered by the physical layer (3GPP TS 45-series of Technical Specifications)
of the MS-BS interface (3GPP TS 45- and 44-series of Technical Specifications). Its main objective is to be a guidance
for the interface between the 3GPP Technical Specifications in the 45-series and the 44-series. It also specifies the
format of signalling channels and the order of bit transmission.
As far as possible, the present document makes use of the layering principles of the Reference Model for Open System
Interconnection (OSI) as contained in ITU-T Recommendations X.200 and X.210.

2 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. These bit streams are transferred on traffic channels, packet data
traffic channels and control channels as defined in 3GPP TS 44.003.
NOTE: For GSM application the physical layer may also be referred to as the radio subsystem. However, the
radio subsystem supports functions additional to those described in the present document.

Figure 2: Interfaces with the Physical Layer
2.1 Interface to the Data Link Layer
The physical layer interfaces the data link layer. On this interface control channels are supported. The data link layer is
specified in 3GPP TS 44.005 and 44.006. Communication between the Physical Layer and the Data Link Layer is in an
abstract way performed by means of PH-primitives. They do not constrain implementations.
NOTE: The terms physical layer and layer 1, and data link layer and layer 2, will be used synonymously in the
present document.
The PH-primitives exchanged between the physical layer and the data link layer are used for the transfer of layer 2
frames. They are also used to indicate the establishment of channels to layer 2.
2.1a Interface to the Radio Link Control and Medium Access
Control layer
The physical layer interfaces the Radio Link Control and Medium Access Control (RLC/MAC) layer. On this interface
packet data control channels and packet data traffic channels are supported when MS is operating in A/Gb m
