name: CCCH
full_form: Common Control Channel
context: A RedCap UE can be identified by the network during Random Access procedure via MSG3/MSGA from a RedCap specific LCID(s) and optionally via MSG1/MSGA (PRACH occasion or PRACH preamble). An eRedCap UE can be identified by the network during Random Access procedure via MSG3/MSGA from an eRedCap specific LCID(s) and optionally via MSG1. For RedCap UE identification via MSG1/MSGA, RedCap specific Random Access configuration may be configured by the network. For eRedCap UE identification via MSG1, eRedCap specific Random Access configuration may be configured by the network. For MSG3/MSGA, an (e)RedCap UE is identified by the dedicated LCID(s) indicated for CCCH identification (CCCH or CCCH1) regardless whether (e)RedCap specific Random Access configuration is configured by the network. (e)RedCap UEs with 1 Rx branch and 2 Rx branches can be allowed separately via system information. In addition, (e)RedCap UEs in Half-Duplex FDD mode can be allowed via system information. A RedCap specific IFRI can be provided in SIB1, when absent, RedCap UEs access is not allowed. An eRedCap specific IFRI can be provided in SIB1, when absent, eRedCap UEs access is not allowed. Information on which frequencies (e)RedCap UE access is allowed can be provided in system information. An (e)RedCap UE with 1 Rx branch applies the associated offset for broadcasted cell specific RSRP thresholds for random access, SDT, cell edge condition and cell (re)selection criterion as specified in TS 38.133[ NR; Requirements for support of radio resource management ]  [13]. NOTE: It is up to the E-UTRA network, if possible, to avoid handover attempts of an (e)RedCap UE to a target NR cell not supporting (e)RedCap. It is up to the (e)RedCap UE implementation, if possible, to recover from handover attempts to a target NR cell not supporting (e)RedCap.
description: The Common Control Channel (CCCH) is a logical channel in cellular networks used for transmitting control information between the network and user equipment. It plays a crucial role in managing random access procedures, including those specific to RedCap and eRedCap UEs. The CCCH is utilized for identifying these UEs via dedicated Logical Channel Identifiers (LCIDs), facilitating their access and camping restrictions within the network.
explanation: CCCH is classified as a Channel because it serves as a medium for control information exchange between the network and user equipment, specifically in the context of random access procedures and UE identification. This aligns with the 3GPP's specifications for efficient network operations.
