8.17 UE UL power control operation with Algorithm 3
25.1013GPPRelease 17TSUser Equipment (UE) radio transmission and reception (FDD)
8.17.1 Minimum requirement
This test verifies that the UE follows only those TPC commands which are transmitted.
Test parameters are specified in Table 8.53. The power control Algorithm 3 is enabled during the test. Before the start of the tests, the UE transmit power shall be initialised to -15 dBm. An actual UE transmit power may vary from the target level of -15 dBm due to inaccurate UE output power step.
After transmission gaps due to discontinuous TPC symbol transmission the uplink transmitter power difference shall be within the range as defined in Table 8.54. The transmit power difference is defined as the difference in power between two transmitted slots corresponding to two consecutive received TPC commands. The on power observation period is defined as the mean power over one timeslot excluding any transient periods.

Note 1: The sequence of uplink TPC commands corresponds to the UL DPCCH slots that are transmitted. During those slots which correspond to UL DPCCH slots that are not transmitted, UP-commands shall be transmitted. |
