UE is the first RLM according to the first configuration information obtained from BS to the PSCell of the UE;Wherein, the PSCell belongs to the serving cell of the UE, and the UE can have at least one PSCell, for PSCell Number be not restricted herein.The UE carries out RLM according to the parameter for RLM obtained from BS to the PSCell of the UE.For example, in case of the UE has 2 PSCell, now the UE obtains two sets of parameters for RLM of BS transmissions, is respectively：

Timing length T310-1, count value N310-1, count value N311-1;

Timing length T310-2, count value N310-2, count value N311-2.

UE uses T310-1, N310-1 and N311-1 to carry out under RLM, ^ mouthfuls of detailed process the first PSCell：

For example, timing length T310-1 is set to 10 seconds, count value N310-1 is set to 3, and count value N311-1 is set to 2;

If UE is continuous N310-1 times（Such as 3 times）Monitor with the first PSCell step-outs, then UE open first timer using timing length T310-1, i.e., the timing or from T310-1 (such as 10 seconds since 0 second）Start countdown；

If UE is continuous N311-1 times（Such as 2 times) monitor to have already turned on the first PSCell synchronizations and first timer, then UE closes first timer；

If first timer time-out is i.e. more than the threshold value of T310-1 (such as 10 seconds), UE detects the first PSCell and occurs RLF;

UE uses T310-2, N310-2 and N311-2 to carry out RLM to the 2nd PSCell, and detailed process is identical with the process that UE carries out RLM to the first PSCell.Likewise, being carried out for remaining PSCell

RLM detailed process is similar to the above, and here is omitted.
