6.3.1 Definition and applicability

Output power dynamics is defined by the MSR BS transmitter’s ability to operate at varying output power levels.

6.3.2 Minimum Requirement

The minimum requirement is in TS 37.104 [2] clause 6.3.

6.3.3 Test purpose

The test purpose is to verify that the output power dynamics are met as specified by the minimum requirement.

6.3.4 Method of test

For this requirement Tables 5.1-1 and 5.2-1 refer to single-RAT specifications; see clause 5, for a BS declared to support CS1 to CS6, CS8 to CS14, CS16 to CS17 or CS19. The following shall apply for a BS declared to support CS1 to CS6, CS8 to CS14, CS16 to CS17 or CS19:

– For references to TS 38.141-1 [26], the method of test is specified in TS 38.141-1 [26], clause 6.3.3.4 and 6.3.4.4.

– For references to TS 36.141 [9], the method of test is specified in TS 36.141 [9], clause 6.3.2.4 and 6.3.3.4.

– For references to TS 25.141 [10], the method of test is specified in TS 25.141 [10], clause 6.4.2.4, 6.4.3.4, 6.4.4.4 and 6.4.5.4.

– For references to TS 25.142 [12], the method of test is specified in TS 25.142 [12], clause 6.4.2.4, 6.4.3.4, 6.4.4.4, 6.4.5.4 and 6.4.6.4.

– For references to TS 51.021 [11], the method of test is specified in TS 51.021 [11], clause 6.3 and 6.4.

If a BS is declared to support CS7, CS15 or CS18, the following shall apply:

– For references to TS 36.141 [9], the method of test is specified in TS 36.141 [9], clause 6.3.2.4 and 6.3.3.4.

– For references to TS 25.141 [10], the method of test is specified in TS 25.141 [10], clause 6.4.2.4, 6.4.3.4, 6.4.4.4 and 6.4.5.4.

– For testing GSM/EDGE output power dynamics, steps in clause 6.3.4.1 and 6.3.4.2 shall apply.

6.3.4.1 Initial conditions for GSM/EDGE output power dynamics for CS7, CS15 or CS18

Base Station RF Bandwidth positions to be tested: M_RFBW in single-band operation, see clause 4.9.1,

1) Set up the equipment as shown in Annex D.1.1.

6.3.4.2 Procedure for GSM/EDGE output power dynamics for CS7, CS15 or CS18

1) Set the BS to transmit according to the applicable test configuration in clause 5 using the corresponding test models or set of physical channels in clause 4.9.2. The highest possible power shall be allocated to GSM carriers taking into account declared rated total output power for Sub-group 2 and maximum supported power difference between carriers.

2) Perform the measurement on a GSM/EDGE carrier as follows: For every measured GSM/EDGE carrier, the requirement and the method of test is specified in TS 51.021 [11], applicable parts of clause 6.3 and 6.4.

In addition, for a multi-band capable BS, the following step shall apply:

– For multi-band capable BS and single band tests, repeat the tests per involved band where single carrier test models shall apply with no carrier activated in the other band. For multi-band capable BS with separate antenna connector, the antenna connector not being under test shall be terminated.

6.3.5 Test Requirement

For E-UTRA, the test requirement is specified in TS 36.141 [9], clause 6.3.2.5.

For UTRA FDD, the test requirement is specified in TS 25.141 [10], clause 6.4.2.5, 6.4.3.5, 6.4.4.5 and 6.4.5.5.
