Class B: B: Automatic choice of of service, Circuit- or or Packet switched, but but only one at at a time (one TRX). Suspension/resumption of of GPRS services at at setup/release of of CS CS connection. Class C: C: Manually selected use of of either Circuit- or or Packet switched service. Special case is is a packet only MS MS (one TRX). 31

36 EDGE - Enhanced Data Rate for GSM Evolution - 36

37 EDGE Modulation Principle Currently: GMSK Modulation Q EDGE: 8PSK Modulation (0,1,0) Q 1 I (0,0,0) (0,1,1) I 0 (0,0,1) (1,1,1) (1,0,1) (1,1,0) (1,0,0) 1 bit per symbol 3 bits per symbol 37

38 Comparison of Data Rates GPRS EGPRS CS4 = 20.0 kbps CS3 = 14.4 kbps CS2 = 12.0 kbps CS1 = 8.0 kbps 8PSK modulated Note: Both GMSK modulated but not the same! MCS9 = 59.2 kbps MCS8 = 54.4 kbps MCS7 = 44.8 kbps MCS6 = 29.6 kbps MCS5 = 22.4 kbps MCS4 = 16.8 kbps MCS3 = 14.8 kbps MCS2 = 11.2 kbps MCS1 = 8.4 kbps 38

45 WCDMA Wideband Code Division Multiple Access High data rates in 5 MHz 384 kbps with wide-area coverage 2 Mbps with local coverage High service flexibility support for services with variable rate support for simultaneous services support of multiple parallel variable-rate services on one connection packet and circuit switched services Fast and efficient packet access Higher capacity 45

46 WCDMA Technical characteristics 5 MHz carriers Frequency Division Duplex, FDD 3.84 Mcps chip rate Variable spreading codes Optimised packet access on common or dedicated channel High spectrum effiency f P MHz t 10 ms frame 46

47 Why Spread Spectrum? Frequency selective fading - Frequency Diversity Interference Averaging Channel Quality Channel Quality f f 47

48 Bit-rate Flexibility WCDMA variability principle: Power is the common shared physical resource Bit rate Power level Spreading factor Varying user bit rate Translates into Varying power level Varying spreading factor 48

49 Power Control What? The Transmitter adapts the output power according to Path Loss Why? Mainly to solve the Near-Far problem Goal is that all users should experience the same SIR How? Open Loop Power control (Initially, No signaling) Inner Loop Power control (Signaling channel, continuously: 1500 times/s, relative changes: up or down) Outer loop Power control (Between BTS and RNC) 49
