19eaceb417a28bf040422bcad9ef7619 | 34.121-1 | 5.6.1 Definition and applicability | A change of TFC (Transport Format Combination) in uplink means that the power in the uplink varies according to the change in data rate. DTX, where the DPDCH is turned off, is a special case of variable data, which is used to minimise the interference between UE(s) by reducing the UE transmit power when voice, user or ... |
19eaceb417a28bf040422bcad9ef7619 | 34.121-1 | 5.6.2 Minimum requirements | A change of output power is required when the TFC, and thereby the data rate, is changed. The ratio of the amplitude between the DPDCH codes and the DPCCH code will vary.

19eaceb417a28bf040422bcad9ef7619 | 34.121-1 | 5.7.2 Minimum requirements | A change of output power is required during uplink compressed frames since the transmission of data is performed in a shorter interval. The ratio of the amplitude between the DPDCH codes and the DPCCH code will also vary. The power step due to compressed mode shall be calculated in the UE so that the energy transmitted... |
