Standards Comparison for Key Measurements on Mobile Stations for cdma2000® and IS-98-C

Detailed notes for key receiver tests 

These notes are arranged by cdma2000 standard number. 

3.1 Frequency requirements 

Band class 0: CDMA channel numbers, frequency assignments and block designators vary. Multiple spreading rates impact channel numbering. Preferred frequency assignments for cdma2000 band class 0 and spreading rate 1 are the same as IS-98-C’s preferred set for both systems A and B. Band class 1: Spreading rate 1 is the same as IS-98-C’s band class 1 channel numbers and frequencies. Preferred frequency assignments for cdma2000 band class 1 and spreading rate 1 are the same as IS-98-C’s preferred set for all block designators. Band class 2 through 7: all are added for cdma2000. 

3.4.1 Demodulation of forward traffic channel in additive white Gaussian noise 

All band classes and all radio configurations should be tested. Tests are to be performed on forward fundamental channel (if supported, otherwise test on forward dedicated control channel). Also, test on forward supplemental and forward supplemental code channels (if they are supported). Closed loop power control must be disabled. 

3.5.2 Single tone desensitization tests 1 and 2 

Tone offset from carrier parameter: +2500 kHz for test 1 and –2500 kHz for test 2. For a spreading rate 3 system, IOR is the received power on each carrier. 

3.5.3 Intermodulation spurious response attenuation 

Tone 1 offset from carrier parameter: +2.50 MHz for test 1, –2.50 MHz for test 2. Tone 2 offset from carrier parameter: +3.30 MHz for test 1, –3.30 MHz for test 2. 

3.5.4 Adjacent channel selectivity 

Measures the ability to receive a CDMA signal on the assigned channel frequency, in the presence of another CDMA signal offset from the assigned channel’s frequency by ±2.5 MHz for spreading rate 1, or ±5 MHz for spreading rate 3. For band class 6 mobiles only. 

Detailed notes for key transmitter tests 4.3.2 and 4.3.3 Reverse pilot channel time and phase error measurements 

Time error must be less than ±10 ns between the reverse pilot channel and all other code channels. Phase error should be less than 0.05 radians and must be less than 0.15 radians. 

4.3.5 Code domain power

This measurement uses a time reference derived from the pilot channel. This time reference is also used for the demodulation of all other code channels. Measured with the waveform quality measurement. 

4.4.1 Range of open loop power 

This test measures the channel power of the mobile station when the base station power is set to low, medium and high values (depends on band class and mobile station class). 

4.4.3 Access probe output power 

This test verifies the same parameters verified in IS-98-C, but for the enhanced access channel as well as the access channel: nominal power offset, initial power offset, power increment between consecutive probes, number of access probes in one probe sequence, and the number of probe sequences in one access attempt. 

4.4.9 Code channel to reverse pilot channel output power accuracy 

Measures code channel output power for the enhanced access channel header, enhanced access channel data, and reverse common control channel data, as well as code channel output power for the reverse traffic channel.
