%X <p>To evaluate the influence of X2 interface time delay in long term evolution-advanced (LTE-A) system, we establish the channel model with time delay and conduct the system level simulation of three typical coordinated multipoint transmission/reception(CoMP) schemes. Finally, we evaluate the system performance at different time delay with different complexity of negotiation. It can be seen that the system performance will degrade with time delay increasing and the system will be more sensitive to delay when the negotiation becomes more complex. What's more, if the X2 interface time delay grows to a certain threshold, it's better not to apply CoMP in LTE-A system.</p>
