31、31 Scope The present document defines the requirements for synchronization on the radio sub-system of the digital cellular telecommunications systems GSM. However, it does not define the synchronization algorithms to be used in the Base Transceiver Station (BTS), CTS Fixed Part (CTS-FP) and Mobile S

32、tation (MS). These are up to the manufacturer to specify. 1.1 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number,

39、05. ETSI ETSI TS 145 010 V13.1.0 (2016-04)73GPP TS 45.010 version 13.1.0 Release 13BTS: Base Transceiver Station. BTTI: Basic TTI. Coverage Class: see definition in 3GPP TS 43.064. CTS-FP: CTS Fixed Part. CTS-MS: MS operating in CTS mode. Current Serving BTS: BTS on one of whose channels (TCH, DCCH,

40、 CCCH or PDCH) the MS is currently operating. Current Serving CTS-FP: CTS-FP on one of whose channels (TCH or CTS control channels) the CTS-MS is currently operating. FANR (Fast Ack/Nack Reporting): Fast Ack/Nack Reporting enables the use of a PAN field within an RLC/MAC block for EGPRS data transfe

41、r or for EGPRS2 data transfer. FANR enables the mobile station to transmit in the uplink direction a PAN field corresponding to a downlink TBF. Similarly FANR enables the network to transmit in the downlink direction a PAN field corresponding to an uplink TBF. MS timing offset: delay of the received

42、 signal relative to the expected signal from an MS at zero distance under static channel conditions with zero timing advance. This is accurate to 1 symbol, and reported once per SACCH or after a RACH as. required (i.e. at the same rate as timing advance). For example, for an MS with a round trip pro

43、pagation delay of P symbols, but with a timing advance of T symbols, the reported timing offset will be P-T quantized to the nearest symbol. For GPRS the MS timing offset is not reported. Normal Symbol Period: duration of a symbol for bursts using a modulating symbol rate of 1625/6 ksymb/s (see 3GPP

44、 TS 45.004); it is equal to 48/13 s. This symbol duration is used for transmission of GMSK, 8PSK, 16QAM and 32QAM modulated bursts on downlink and GMSK, 8PSK and 16QAM modulated bursts on uplink (see 3GPP TS 45.004). Observed Frequency Offset (OFO): difference of frequency of signals received by a C

45、TS-MS from a CTS-FP and a BTS. The Observed Frequency Offset is measured and reported by the CTS-MS on CTS-FP requirement. The Observed Frequency Offset is expressed in ppm with an accuracy of 1/64 ppm (i.e. about 0,016 ppm). PAN: Piggy-backed Ack/Nack. Quarter symbol number: timing of quarter symbo

46、l periods (12/13 s or 10/13 s depending on the actual symbol period used) within a timeslot. A symbol can represent 1 to 5 bits depending upon modulation. Reduced Latency: refers to the use of FANR either in BTTI configuration or in RTTI configuration for EGPRS and EGPRS2. Reduced Symbol Period: dur

47、ation of a symbol for bursts using a modulating symbol rate of 325 ksymb/s (see 3GPP TS 45.004); it is equal to 40/13 s. This symbol duration is used for transmission of QPSK, 16QAM and 32QAM modulated bursts on uplink and downlink (see 3GPP TS 45.004). RTTI: Reduced TTI. Symbol Period: symbol perio

48、d is the duration of a symbol and shall refer to normal symbol period unless explicitly clarified to be the reduced symbol period. TDMA frame number: count of TDMA frames relative to an arbitrary start point. Timebase counters: set of counters which determine the timing state of signals transmitted

49、by a BTS or MS. Time group (TG): used for compact, time groups shall be numbered from 0 to 3 and a particular time group shall be referred to by its time group number (TG) (see 3GPP TS 45.002). Timeslot number: timing of timeslots within a TDMA frame. Timing Advance: signal sent by the BTS to the MS which the MS uses to advance its timings of transmissions to the BTS so as to compensate for propagation delay.
