Max Occupied Bandwidth Test

The existing test is defined for single-carrier operation only. The test is extended to include multi-carrier operation In multi-carrier operation, the occupied

bandwidth is defined as the frequency range, whereby the power of emissions averaged over the frequency above the edge frequency of the rightmost carrier and under the edge frequency of the leftmost carrier are 0.5% each of the total radiation power of all modulated carriers.

The test ensures that the occupied bandwidth does not exceed limits specified for adjacent carriers as well as a carrier pair at maximum separation

Minimum Standard

04/21/23 QUALCOMM Proprietary

In the multiple carrier transmission, the occupied bandwidth for each carrier still remains within 1.48 MHz. Based on this assumption, the following minimum standards are defined.

For the test with two reverse CDMA channels at maximum frequency separation, the occupied bandwidth shall not exceed MaxReverseLinkBandwidth × 0.0025 + 1.48MHz. For the test with two or more adjacent reverse CDMA channels, the occupied bandwidth shall not exceed (N-1) × M + 1.48 MHz where N is the number of reverse CDMA channels and M is the minimum carrier spacing used in a Band Class.

Correction to transmitter spurious emission limits

The existing transmitter spurious emission limits for Test 2 in multi-carrier transmission (Table 4.4.1.3-8 of C.S0033-B) has overlooked ITU Category B limit. This is inconsistent with Test 1 (Table 4.4.1.3-2) and Test 3 (Table 4.4.1.3-9).

We propose to amend Table 4.4.1.3-8 to include ITU Category B limit. For Test 2, ITU Category B limit is intended to apply only to Band Classes 6 and 8.
