21、sion 5.4.0: April 1998 1.2 Abbrevlatlons Abbreviations used in this GTS are listed in GSM 01.04 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

22、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: - -

23、- - - - - - - cell broadcast channel (CBCH). full rate speech TCH (TCH/FS); half rate speech TCH (TCH/HS); 14,4 kbit/s full rate data TCH (TCH/F14.4) 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); I2,4 kbit/s full rate da

24、ta TCH (TCH/F2.4); I2,4 kbit/s half rate data TCH (TCH/H2.4); All channels are bi-directional unless otherwise stated. Unidirectional downlink full rate channels, TCH/FD are defined as the downlink part of the corresponding TCH/F. Unidirectional uplink full rate channels are FFS. Multislot configura

25、tions are defined as multiple (1 up to 8) full rate channels allocated to the same MS. At least one channel shall be bi-directional (TCH/F). The multislot configuration is symmetric if all channels are bi-directional (TCH/F) and asymmetric if at least one channel is unidirectional (TCH/FD) . High Sp

26、eed Circuit Switched Data (HSCSD) is an example of multislot configuration, in which all channels shall have the same channel mode. NOTE: For the maximum number of timeslots to be used for a HSCSD configuration, see GSM 03.34. 2) The signalling channels: these can be sub-divided into BCCH (broadcast

27、 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 bur

28、st 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 channe

29、l, 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 (SACCHTTH); - slow, TC

30、H/F associated, control channel for multislot configurations (SACCH/M); - slow, SDCCHM associated, control channel (SACCH/C4); STD-ETSI GSM 05.OL-ENGL 1798 m 3Li00855 0300b7b 883 Page 9 GSM 05.01 version 5.4.0: April 1998 - slow, SDCCH/8 associated, control channel (SACCH/C8): - broadcast control ch

31、annel (BCCH); - random access channel (.e. uplink CCCH) (RACH); - paging channel (part of downlink CCCH) (PCH); - access grant channel (part of downlink CCCH) (AGCH); - notification channel (part of downlink CCCH) (NCH). All associated control channels have the same direction (bi-directional or unid

32、irectional) as the channels they are associated to. The unidirectional SACCH/MD is defined as the downlink part of SACCH/M. 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 (SACC

33、H will mean all categories of SACCHs, SACCH/T will mean both the slow, TCH associated, control channels, etc.). 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 transmissio

34、n 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 p

35、arts 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

36、 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 configuratio

37、n 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 t

38、o a flow of information that is actually encrypted.

42、 060/13 (= 235) ?e block is divided into two classes accordina to the imDortance 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 Il). For data s

43、ervices, the net bit rate is the adaptation rate as defined in GSM 04.21. On SACCH, 16 bits are reserved for control information 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 (m, n, p, r) per recurrence period is adju

44、stable on a cell by cell basis and depends upon the parameters (BSCC-CHANS, BS-BCCH-SDCCH-COMB, BSAG-BLKS-RES and NCP) broadcast on the BCCH and specified in GSM 05.02 and GSM 04.08.

45、ril 1998 5 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 fre

46、quency hopping sequence. The basic radio resource is a time slot lasting = 576,9 ps (15/26 ms) and transmitting information at a modulation rate of = 270.833 kbis (1 62516 kbit/s). This means that the time slot duration, including guard time, is 156,25 bit durations. We shall describe successively t

47、he 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. T

48、he longest recurrent time period of the structure is called hyperframe and has a duration of 3 h 28 mn 53 s 760 ms (or 12 533,76 s). The TDMA frames are numbered modulo this hyperframe (TDMA frame number, or FN, from O to 2 715 647). This long period is needed to support cryptographic mechanisms def

49、ined 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 SACCHlT) and FACCH; - a 51-frame multiframe (26 per superframe) with a duration of = 235,4 ms (3 060/13 ms), comprising 51 TDMA frames. This multiframe is
