`
`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), and is
`now submitted for the Unified Approval Procedure phase of the ETSI standards approval procedure.
`
`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 fouth 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 4.6.0.
`
`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.

`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.

`
`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 [5]:
`
`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)
`
`-
`-
`-
`-
`-
`-
`-
`-
`
`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:
`
`1)
`
`
`
`2)
`
`
`
`-
`
`-
`
`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.

`
`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.

`NOTE 1:
`
`
`NOTE 2:
`
`For full rate speech, the block is divided into two classes according to the importance of
`the bits (182 bits for class I and 78 bits for class II).
`
`For half rate speech, the block is divided into two classes according to the importance of
`the bits (95 bits for class I and 17 bits for class II).
`
`For data services, the net bit rate is the adaptation rate as defined in GSM 04.21.
`
`
`NOTE 3:
`
`NOTE 4: On SACCH, 16 bits are reserved for control information on layer 1, and 168 bits are used
`for higher layers.
`
`
`NOTE 5:
`
`CCCH channels are common to all users of a cell; the total number of blocks (n, p, r) per
`recurrence period is adjustable on a cell by cell basis and depends upon the parameters
`(BS_CC_CHANS, BS_BCCH_SDCCH_COMB and BS_AG_BLKS_RES) broadcast on the
`BCCH and specified in GSM 05.02 and GSM 04.08.

`
`Multiple access and timeslot structure
`
`The access scheme is Time Division Multiple Access (TDMA) with eight basic physical channels per
`carrier. The carrier separation is 200 kHz. A physical channel is therefore defined as a sequence of TDMA
`frames, a time slot number (modulo 8) and a frequency hopping sequence.
`
`The basic radio resource is a time slot lasting  576.9µs (15/26 ms) and transmitting information at a
`modulation rate of  270.833 kbit/s (1625/6 kbit/s). This means that the time slot duration, including guard
`time, is 156.25 bit durations.
`
`We shall describe successively the time frame structures, the time slot structures and the channel
`organization. The appropriate specifications will be found in GSM 05.02 (multiplexing and multiple
`access).
`
`5.1
`
`Hyperframes, superframes and multiframes
`
`A diagrammatic representation of all the time frame structures is in figure 1. The longest recurrent time
`period of the structure is called hyperframe and has a duration of 3h 28mn 53s 760ms (or 12533.76 s).
`The TDMA frames are numbered modulo this hyperframe (TDMA frame number, or FN, from 0 to
`2715647). This long period is needed to support cryptographic mechanisms defined in GSM 03.20.
`
`One hyperframe is subdivided in 2048 superframes which have a duration of 6.12 seconds. The
`superframe is the least common multiple of the time frame structures. The superframe is itself subdivided
`in multiframes; two types of multiframes exist in the system:
`
`-
`
`-
`
`a 26-frame multiframe (51 per superframe) with a duration of 120 ms, comprising
`26 TDMA frames. This multiframe is used to carry TCH (and SACCH/T) and FACCH.
`a 51-frame multiframe (26 per superframe) with a duration of 235.4 ms (3060/13 ms),
`comprising 51 TDMA frames. This multiframe is used to carry BCCH, CCCH (AGCH,
`PCH and RACH) and SDCCH (and SACCH/C).
`
`
`A TDMA frame, comprising eight time slots has a duration of  4.62 (60/13) ms.
`
`5.2
`
`Time slots and bursts
`
`The time slot is a time interval of  576.9 µs (15/26 ms), that is 156.25 bit durations, and its physical
`content is called a burst. Four different types of bursts exist in the system. A diagram of these bursts
`appears in figure 1.
`
`normal burst (NB): this burst is used to carry information on traffic and control
`channels, except for RACH. It contains 116 encrypted bits and includes a guard time
`of 8.25 bit durations ( 30.46 µs).
`frequency correction burst (FB): this burst is used for frequency synchronization of the
`mobile. It is equivalent to an unmodulated carrier, shifted in frequency, with the same
`guard time as the normal burst. It is broadcast together with the BCCH. The repetition
`of FBs is also named frequency correction channel (FCCH).
`synchronization burst (SB): this burst is used for time synchronization of the mobile. It
`contains a long training sequence and carries the information of the TDMA frame
`number (FN) and base station identity code (BSIC, see GSM 03.03). It is broadcast
`together with the frequency correction burst. The repetition of synchronization bursts is
`also named synchronization channel (SCH).
`access burst (AB): this burst is used for random access and is characterized by a
`longer guard period (68.25 bit durations or 252 µs) to cater for burst transmission from
`a mobile which does not know the timing advance at the first access (or after
`handover). This allows for a distance of 35 km. This burst is used in the RACH and
`after a handover. In exceptional cases of cell radii larger than 35 km, some possible
`measures are described in GSM 03.30.

`5.3
`
`Channel organization
`
`The channel organization for the traffic channels (TCH), FACCHs and SACCH/T uses the 26-frame
`multiframe. It is organized as described in figure 2, where only one time slot per TDMA frame is
`considered.
`
`Figure 2: Traffic channel organization
`
`
`
`The FACCH is transmitted by preempting half or all of the information bits of the bursts of the TCH to
`which it is associated (see GSM 05.03).
`
`The channel organization for the control channels (except FACCHs and SACCH/T) uses the 51-frame
`multiframe. It is organized in the downlink and uplink as described in figure 3.
`

`
`Frequency hopping capability
`
`The frequency hopping capability is optionally used by the network operator on all or part of its network.
`The main advantage of this feature is to provide diversity on one transmission link (especially to increase
`the efficiency of coding and interleaving for slowly moving mobile stations) and also to average the quality
`on all the communications through interferers diversity. It is implemented on all mobile stations.
`
`The principle of slow frequency hopping is that every mobile transmits its time slots according to a
`sequence of frequencies that it derives from an algorithm. The frequency hopping occurs between time
`slots and, therefore, a mobile station transmits (or receives) on a fixed frequency during one time slot (
` 577 µs) and then must hop before the time slot on the next TDMA frame. Due to the time needed for
`monitoring other base stations the time allowed for hopping is approximately 1 ms, according to the
`receiver implementation. The receive and transmit frequencies are always duplex frequencies.
`
`The frequency hopping sequences are orthogonal inside one cell (ie no collisions occur between
`communications of the same cell), and independent from one cell to an homolog cell (ie using the same
`set of RF channels, or cell allocation). The hopping sequence is derived by the mobile from parameters
`broadcast at the channel assignment, namely, the mobile allocation (set of frequencies on which to hop),
`the hopping sequence number of the cell (which allows different sequences on homolog cells) and the
`index offset (to distinguish the different mobiles of the cell using the same mobile allocation). The non-
`hopping case is included in the algorithm as a special case. The different parameters needed and the
`algorithm are specified in GSM 05.02.
`
`In case of multi band opertaion frequency hopping channels in different bands of opertaion, e.g. between
`channels in GSM and DCS, is not supported. Frequency hopping within each of the bands supported shall
`be implemented in the mobile station.
`
`It must be noted that the basic physical channel supporting the BCCH does not hop.

`
`Coding and interleaving
`
`A brief description of the coding schemes that are used for the logical channels mentioned in section 2,
`plus the synchronization channel (SCH, see 5.2), is made in the following table. For all the types of
`channels the following operations are made in this order:
`
`-
`-
`-
`
`external coding (block coding);
`internal coding (convolutional coding);
`interleaving.
`
`
`
`After coding the different channels (except RACH and SCH) are constituted by blocks of coded
`information bits plus coded header (the purpose of the header is to distinguish between TCH and FACCH
`blocks). These blocks are interleaved over a number of bursts. The block size and interleaving depth are
`channel dependent. All these operations are specified in GSM 05.03.

`demodulation).

`
`Transmission and reception
`
`The modulated stream is then transmitted on a radio frequency carrier. The frequency bands and channel
`arrangement are the following.
`
`i)
`
`
`ii)
`
`
`iii)
`
`
`Standard or primary GSM900 Band, P-GSM;
`For Standard GSM 900 Band, the system is required to operate in the following frequency band:
`
`890 - 915 Mhz: mobile transmit, base receive
`
`935 - 960 Mhz: base transmit, mobile receive
`
`Extended GSM 900 Band, E-GSM (includes Standard GSM 900 band);
`For Extended GSM 900 Band, the system is required to opertate in the following frequency band:
`
`880 - 915 Mhz: mobile, base receive
`
`925 - 960 Mhz: base transmit, mobile receive
`
`DCS1800 Band
`For DCS 1800, the system is required to operate in the following frequency band:
`
`1710 - 1785 Mhz: mobile transmit, base receive
`
`1805 - 1880 Mhz: base transmit, mobile receive
`
`
`NOTE:
`
`The term GSM 900 is used for any GSM system which operates in any 900 Mhz band.
`
`Operators may implement networks on a combination of the frequency bands above to support multi band
`mobile stations which are defined in GSM 02.06.
`
`The RF channel spacing is 200 kHz, allowing for 174 (GSM 900) and 374 (DCS 1800) radio frequency
`channels, thus leaving a guard band of 200 kHz at each end of the subbands.
`
`The specific RF channels, together with the requirements on the transmitter and the receiver will be found
`in GSM 05.05 (Transmission and reception).
`
`In order to allow for low power consumption for different categories of mobiles (eg. vehicle mounted,
`hand-held, ..), different power classes have been defined. For GSM 900 there are four power classes with
`the maximum power class having 8 W peak output power (ca 1 W mean output power) and the minimum
`having 0.8 W peak output power. For DCS 1800 there are three power classes of 4 W peak output power,
`1 W peak output power (ca 0.125 W mean) and 0.25 W peak output power.
`
`Multi band mobile stations may have any combinations of the allowed power classes for each of the bands
`supported.
`
`The power classes are specified in GSM 05.05.
`
`The requirements on the overall transmission quality together with the measurement conditions are also in
`GSM 05.05.

`
`10 Other layer 1 functions
`
`The transmission involves other functions. These functions may necessitate the handling of specific
`protocols between BS and MS. Relevant topics for these cases are:
`
`the power control mechanisms which adjust the output level of the mobile station (and
`optionally of the base station) in order to ensure that the required quality is achieved with the
`less possible radiated power. Power levels with 2 dB steps have been defined for that
`purpose. This is described in GSM 05.08 (radio subsystem link control) and GSM 05.05.
`
`the synchronization of the receiver with regard to frequency and time (time acquisition and
`time frame alignment). The synchronization problems are described in GSM 05.10
`(synchronization aspects).
`
`the hand-over and quality monitoring which are necessary to allow a mobile to continue a call
`during a change of physical channel. This can occur either because of degradation of the
`quality of the current serving channel, or because of the availability of another channel which
`can allow communication at a lower Tx power level, or to prevent a MS from grossly
`exceeding the planned cell boundaries. The choice of the new channel is done by the
`network (base station control and MSC) based on measurements (on its own and on
`adjacent base stations) that are sent on a continuous basis by the mobile station via the
`SACCHs. The requirements are specified in GSM 05.08 (radio subsystem link control).
`
`the measurements and sub-procedures used in the first selection or reselection of a base
`station by a mobile are specified in GSM 05.08 (radio subsystem link control). (The overall
`selection and reselection procedures, together with the idle mode activities of a mobile are
`defined in GSM 03.22 (functions related to MS in idle mode).)

`
`Performance
`
`Under typical urban fading conditions (ie multipath delays no greater than 5 µs), the quality threshold for
`full-rate speech is reached at a C/I value of approximately 9 dB. The maximum sensitivity is approximately
`-104 dBm for base stations and GSM mobiles and -102 dBm and -100 dBm for GSM 900 small MSs (see
`GSM 05.05) and DCS 1800 hand-helds, respectively.
`
`Multi band mobile stations shall meet the reqirements on each band of operation respectively.
