name: DPCCH2
full_form: Dedicated Physical Control Channel 2
context: For the primary uplink frequency, the uplink inner-loop power control for DPCCH2 adjusts the uplink DPCCH2 transmit power in order to maintain reliable reception of DPCCH2. The HS-DSCH serving cell in the active set monitors the DPCCH2 quality and provides TPC commands to adjust the uplink DPCCH2 transmit power. To increase the UE transmit power of DPCCH2 the TPC command to transmit is "1", and to decrease the power the TPC command to transmit is â0â. The TPC command associated with DPCCH2 is not required to be transmitted in any downlink slot starting during an uplink DPCCH2 slot in which the DPCCH2 is not transmitted. Algorithm 1 as described in subclause 5.1.2.2.2.1, shall be used for processing TPC commands associated with DPCCH2, i.e. only one TPC command is received in each slot from the HS-DSCH serving cell. After deriving the TPC command TPC_cmd associated with DPCCH2, the UE shall adjust the transmit power of the uplink DPCCH2 with a step of ïDPCCH2 (in dB) which is given by:
description: The Dedicated Physical Control Channel 2 (DPCCH2) is an uplink channel used for transmitting control information, such as power control commands, from the User Equipment (UE) to the base station. It plays a crucial role in maintaining reliable reception of control signals and adjusting the UE's transmit power accordingly.
explanation: The context describes DPCCH2 as an uplink channel specifically used for transmitting control information related to power control between the UE and the base station. This function aligns with the definition of a Channel entity type, which facilitates communication and data transfer within a telecommunications system.
