Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI).
This ETS describes, in general terms, the physical layer on the radio path of GSM and DCS 1800 within
the European digital cellular telecommunications system (Phase 2).
This third edition of ETS 300 573 has been introduced as a result of further work carried out by TC-SMG.
This ETS corresponds to GSM technical specification, GSM 05.01 version 4.5.0.
The specification from which this ETS has been derived was originally based on CEPT documentation,
hence the presentation of this ETS may not be entirely in accordance with the ETSI/PNE rules.
Reference is made within this ETS to GSM Technical Specifications (GSM-TSs) (NOTE).
NOTE: TC-SMG has produced documents which give the technical specifications for the
implementation of the European digital cellular telecommunications system.
Historically, these documents have been identified as GSM Technical Specifications
(GSM-TSs). These TSs may have subsequently become I-ETSs (Phase 1), or ETSs
(Phase 2), whilst others may become ETSI Technical Reports (ETRs). GSM-TSs are,
for editorial reasons, still referred to in GSM ETSs.
Transposition dates

Date of latest announcement of this ETS (doa): 31 December 1995
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 30 June 1996

1 Scope
This European Telecommunication Standard (ETS) is an introduction to the 05 series of the GSM
technical specifications for GSM and DCS 1800. It is not of a mandatory nature, but consists of a general
description of the organization of the physical layer with reference to the technical specifications where
each part is specified in detail. It introduces furthermore, the reference configuration that will be used
throughout this series of technical specifications.
1.1 Normative references
This ETS incorporates by dated and undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references, the
latest edition of the publication referred to applies.

1.2 Abbreviations
Abbreviations used in this ETS are listed in GSM 01.04.
2 Set of channels
The radio subsystem provides a certain number of logical channels that can be separated into two
categories according to GSM 04.03:
1) the traffic channels (TCH): they are intended to carry two types of user information streams:
encoded speech and data. Two types of traffic channels are defined: Bm or full-rate (TCH/F)
and Lm or half-rate (TCH/H) traffic channels. For the purpose of this series of technical
specifications, the following traffic channels are distinguished:
- full rate speech TCH (TCH/FS)
- half rate speech TCH (TCH/HS)
- 9.6 kbit/s full rate data TCH (TCH/F9.6)
- 4.8 kbit/s full rate data TCH (TCH/F4.8)
- 4.8 kbit/s half rate data TCH (TCH/H4.8)
- 2.4 kbit/s full rate data TCH (TCH/F2.4)
- 2.4 kbit/s half rate data TCH (TCH/H2.4)
- cell broadcast channel (CBCH)
2) the signaling channels: these can be sub-divided into BCCH (broadcast control channel),
CCCH (common control channel), SDCCH (stand-alone dedicated control channel) and
ACCH (associated control channel). An associated control channel is always allocated in
conjunction with, either a TCH, or a SDCCH. Two types of ACCH are defined: continuous
stream (slow ACCH) and burst stealing mode (fast ACCH). For the purpose of this series of
technical specifications, the following signalling channels are distinguished:
- stand-alone dedicated control channel, four of them mapped on the same basic
physical channel as the CCCH (SDCCH/4)
- stand-alone dedicated control channel, eight of them mapped on a separate basic
physical channel (SDCCH/8)
- full rate fast associated control channel (FACCH/F)
- half rate fast associated control channel (FACCH/H)
- slow, TCH/F associated, control channel (SACCH/TF)
- slow, TCH/H associated, control channel (SACCH/TH)
- slow, SDCCH/4 associated, control channel (SACCH/C4)
- slow, SDCCH/8 associated, control channel (SACCH/C8)
- broadcast control channel (BCCH)
- random access channel (ie uplink CCCH) (RACH)
- paging channel (part of downlink CCCH) (PCH)
- access grant channel (part of downlink CCCH) (AGCH)
When there is no need to distinguish between different sub-categories of the same logical channel, only
the generic name will be used, meaning also all the sub-categories (SACCH will mean all categories of
SACCHs, SACCH/T will mean both the slow, TCH associated, control channels,.).
The logical channels mentioned above are mapped on physical channels that are described in this set of
technical specifications. The different physical channels provide for the transmission of information
pertaining to higher layers according to a block structure.

3 Reference configuration
For the purpose of elaborating the physical layer specification, a reference configuration of the
transmission chain is used as shown in annex A. This reference configuration also indicates which parts
are dealt with in details in which technical specification. It shall be noted that only the transmission part is
specified, the receiver being specified only via the overall performance requirements. With reference to
this configuration, the technical specifications in the 05 series address the following functional units:
- GSM 05.02: burst building, and burst multiplexing;
- GSM 05.03: coding, reordering and partitioning, and interleaving;
- GSM 05.04: differential encoding, and modulation;
- GSM 05.05: transmitter, antenna, and receiver (overall performance).
This reference configuration defines also a number of points of vocabulary in relation to the name of bits
at different levels in the configuration. It must be outlined, in the case of the encrypted bits, that they are
named only with respect to their position after the encryption unit, and not to the fact that they pertain to a
flow of information that is actually encrypted.
