Abstract: An apparatus and system for power saving in a user equipment (UE) are described. The UE uses signal-to-interference-plus-noise (SINR) of radio link monitoring (REM) signals to determine whether to enter or exit a relaxation state in which the frequency of measurement of the REM signals is reduced, as is feedback to the base station. The REM relaxation state is dependent on the average SINR of the REM signals over a predetermined time window. Alternatively, the REM relaxation state is dependent on SINR thresholds that include an SINR fluctuation range using a SINR threshold for REM in-sync or derived from a Cumulative Distribution Function (CDF) curve of SINR using a predetermined maximum SINR fluctuation.
