1. A method for determining triggering of a conditional handover, comprising:
estimating, using a line-of-sight (LoS) channel, a received signal power as a function of a blocker that simulates a human body;
determining multiple stages of potential blockage of the received signal power by the blocker:
predicting, using long-short-term memory (LTSM), a channel state and the potential blockage; and
determining whether to trigger the conditional handover based on the predicted channel state and potential blockage.
