name: DCCH
full_form: Dedicated Control Channel
context: CCCH mapped to RACH/FACH: - TCTF field is included in MAC header. In FDD and 1.28 Mcps TDD, CCCH mapped to HS-DSCH and to E-DCH: - no MAC-c header is included. Figure 9.2.1.4-1: MAC PDU format for CCCH mapped to RACH/FACH Figure 9.2.1.4-2: MAC-c PDU format for CCCH mapped to HS-DSCH or E-DCH (FDD and 1.28 Mcps TDD only)
description: The Dedicated Control Channel (DCCH) is a type of channel in the Universal Mobile Telecommunications System (UMTS) used for transmitting control information between the network and user equipment. It is utilized when there is a need to send dedicated control messages, such as signaling data, rather than using shared channels. The DCCH plays a crucial role in managing communication sessions, handling mobility, and ensuring efficient use of radio resources.
explanation: The context describes the DCCH's function within the UMTS network, emphasizing its role in dedicated control communications, similar to other channel types defined in telecommunications.
