name: SCCH
full_form: Sidelink Control Channel
context: The AS protocol stack for the control plane for SCCH for RRC in the PC5 interface consists of RRC, PDCP, RLC and MAC sublayers, and the physical layer. The protocol stack of control plane for SCCH for RRC is shown in Figure 16.9.2.1-1. Figure 16.9.2.1-1: Control plane protocol stack for SCCH for RRC. For support of PC5-S protocol specified in TS 23.287 [40], PC5-S is located on top of PDCP, RLC and MAC sublayers, and the physical layer in the control plane protocol stack for SCCH for PC5-S, as shown in Figure 16.9.2.1-2. Figure 16.9.2.1-2: Control plane protocol stack for SCCH for PC5-S. The AS protocol stack for SBCCH in the PC5 interface consists of RRC, RLC, MAC sublayers, and the physical layer as shown below in Figure 16.9.2.1-3. Figure 16.9.2.1-3: Control plane protocol stack for SBCCH. The AS protocol stack for user plane in the PC5 interface consists of SDAP, PDCP, RLC and MAC sublayers, and the physical layer. The protocol stack of user plane is shown in Figure 16.9.2.1-4.
description: The Sidelink Control Channel (SCCH) facilitates direct communication between devices via sidelink, bypassing the base station. It operates within the PC5 interface and transmits control information essential for sidelink functionality.
explanation: The text explicitly states that SCCH is a 'control channel' used for 'side link communication'.  Control channels are dedicated to transmitting signaling and management information within telecommunications systems.
