name: CCH
full_form: Control Channel
context: When the UE has been allocated by higher layers to receive data on DSCH using the TFCI, the UE shall decode the PDSCH in the following cases: - In case of a standalone PDSCH the TFCI is located on the PDSCH itself, then the UE shall decode the TFCI and based on which data rate was indicated by the TFCI, the decoding shall be performed. The UE shall decode PDSCH only if the TFCI word decode corresponds to the TFC part of the TFCS given to the UE by higher layers. - In case that the TFCI is located on the DCH, the UE shall decode the PDSCH frame or frames if the TFCI on the DCH indicates the need for PDSCH reception. Upon reception of the DCH time slot or time slots, the PDSCH slot (or first PDSCH slot) shall start SFN n+2 after the DCH frame containing the TFCI, where n indicates the SFN on which the DCH is received. In the case that the TFCI is repeated over several frames, the PDSCH slot shall start SFN n+2 after the frame having the DCH slot which contains the last part of the
description: The Control Channel (CCH) carries control plane data, including signaling messages and control information, in the UTRAN (UMTS Terrestrial Radio Access Network). It enables communication between the User Equipment (UE) and the network for controlling various aspects of the connection.
explanation: The text explicitly refers to the CCH as a "type of channel" within the UTRAN architecture. Its function is described as carrying control plane data essential for network communication and connection management, aligning with the definition of a telecommunications channel.
