9、 (doa): 30 April 1996 20 August 1996 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 rad
10、io path of GSM and DCS 1800 within the European digital cellular telecommunications system (Phase 2). This fourth 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 specificat
11、ion 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 ETSIPNE rules. Reference is made within this ETS to GSM Technical Specifications (GSM-TSs) (note). Date of latest publication of new Nati

23、viations used in this ETS are listed in GSM O1 .O4 l. 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 5: 1) the traffic channels (TCH): they are intended to carry two types of user information stream
24、s: encoded speech and data. Two types of traffic channels are defined: Bm or full-rate (TCHF) and Lm or half-rate (TCWH) traffic channels. For the purpose of this series of technical specifications, the following traffic channels are distinguished: - - - - - - - - cell broadcast channel (CBCH) full
25、rate speech TCH (TCHIFS) half rate speech TCH (TCWHS) 9,6 kbis full rate data TCH (TCwF9,S) 4,8 kbis full rate data TCH (TCwF4,8) 4.8 kbis half rate data TCH (TCH/H4,8) s 2,4 kbit/s full rate data TCH (TCH/F2,4) s2,4 kbit/s half rate data TCH (TCH/H2,4) 2) the signaling channels: these can be subdiv
26、ided 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 s
27、tream (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 (SDCCHM) - stand-alone d
28、edicated control channel, eight of them mapped on a separate basic physical channel (SDCCH/8) - full rate fast associated control channel (FACCHF) - half rate fast associated control channel (FACCHR1) - slow, TCWF associated, control channel (SACCWTF) - slow, TCWH associated, control channel (SACCWH
29、) - slow, SDCCH/4 associated, control channel (SACCH/C4) - slow, SDCCH18 associated, control channel (SACCHK8) - broadcast control channel (BCCH) - random access channel (e uplink CCCH) (RACH) - paging channel (part of downlink CCCH) (PCH) - access grant channel (part of downlink CCCH) (AGCH) When t
30、here 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, SACCHTT will mean both the slow, TCH associated, control channels,). The logical channels me
31、ntioned 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. ETSI ETS*300*573 96 = 3400855 OLOY578 526 D Page 9 ETS 300
32、 573: May 1996 (GSM 05.01 version 4.6.0) 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 wh
33、ich 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: - - - -
34、 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
35、 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 actu
36、ally encrypted.

A summarised description appears in table 1, in terms of net bit rate, len
37、gth and recurrence of blocks. net bit rate (kbitis) 13,O 5,6 12,o 6,O 3,6 912 4,6 598/765 (= 0,782) 11 51300 (= 0,383) 299/765 (= 0,391) 598/765 (= 0,782) n59W65 (= 0,782) r*26/765 (= 0,034) 598/765 (= 0,782) p*598/765 (= 0,782) Table 1: Channel block structures block length (bits) 182 + 78 95+ 17 6

40、or class li). 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 Il). For data services, the net bit rate is the adaptation rate as defined in GSM 04.21. On SACCH, 16 bits are reserved for control information
41、 on layer 1 , and 168 bits are used for higher layers. CCCH channels are common to all users of a cell; the total number of blocks (n, p, r) pei recurrence period is adjustable on a cell by cell basis and depends upon the parameters (BS-CC-CHANS, BS-BCCH-SDCCHCOMB and BS-AG-BLKS-RES) broadcast on th
42、e BCCH and specified in GSM 05.02 and GSM 04.08.

43、l 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 = 576.9s (15/26 ms) and transmitting information at a modul
44、ation rate of = 270,833 kbits (1625/6 kbits). 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
45、.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 TDM
46、A frames are numbered modulo this hyperframe (TDMA frame number, or FN, from O 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
47、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 SACCHTT) and FACCH. a
48、 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 b
49、ursts The time slot is a time interval of = 576,9 ps (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 ps). frequency correction burst (FB): this burst is used for frequency synchronization of the mobile. It is equivalent to an unmodulate
