al channels. In FDD, it is a closed loop process receiving quality target from UL outer loop power control and quality estimates of the uplink dedicated physical control channel. The UE gets power control commands on the downlink dedicated physical control channel. Resides in both the UTRAN and the UE. In TDD located in the UE, it is a open loop process receiving quality target from the UL outer loop power control and uses the quality target and quality estimates of downlink channels to set the transmit power. This function located in both UTRAN and UE, sets the power of the downlink dedicated physical channels while receiving the quality target from DL outer loop power control and quality estimates of the downlink dedicated physical control channel. Power control commands are sent on the uplink dedicated physical control channel to the UTRAN. Open Loop This function located in both UTRAN and UE sets the initial power of the UE at random access. It uses UE measurements and broadcasted cell/system parameters as input Function located in both UTRAN and UE, sets the initial power of downlink channels. It receives downlink measure- ment reports from the UE 3.4.5.8 Radio Channel Coding and Control This function located in both UE and UTRAN brings redundancy into the data source flow, thereby increasing its rate by adding information calculated from the data source. This allows detection or correction of signal errors introduced by the transmission me- dium. Channel coding algorithm(s) and redundancy level may vary in the different types of logical channels and different types of data. Channel coding control residing in both UE and UTRAN, generates control information required by the channel coding/ decoding execution functions, e.g. channel coding type, code rate, etc. 3.4.5.9 Radio Channel Decoding Channel decoding aims to reconstruct the information source using the added redun- dancy by the channel coding function to detect or correct possible errors in the received data flow. This function may also employ a priori
