name: SS
full_form: Synchronisation Shift
context: This logical channel is used for a p-t-m downlink transmission of MBMS service transmission schedule between network and UEs in RRC Connected or Idle Mode. The control plane rmation on MSCH is MBMS service and S-CCPCH specific and is sent to UEs in a cell receiving MTCH. One MSCH is sent in each S-CCPCH carrying the MTCH. The MSCH is always mapped to one specific FACH in the S-CCPCH as indicated on the MCCH. Due to different error requirements the MSCH is mapped to a different FACH than MTCH. If MSCH is the only logical channel mapped in to the FACH, the absence of the TCTF field is explicitly signalled otherwise the TCTF field is used in MAC header to identify MSCH logical channel type.
description: The Synchronisation Shift (SS) is a control signal sent in the downlink to instruct a timing adjustment every M frames. It is an L1 control signal, with a length of 1 symbol, and its coding is shown in tables 18 and 19 for different service scenarios.
explanation: The SS is classified as a Control Signal because it is explicitly stated to 'instruct a timing adjustment', indicating its function is to regulate and manage the timing within the telecommunications system.
