METHOD FOR DETERMINING TIMING ADVANCE, USER EQUIPMENT AND BASE STATION

摘要

The embodiment of the present document provides a method, user equipment and base station for determining a timing advance, which can support a larger cell radius without changing the protocol, the required device complexity is low, and with the UE side transmitting msg3 by using different TA adjustments to obtain a correct timing deviation value, the access delay of the PRACH is minimized, and the overhead of the PRACH sub-frame will not be increased, which can prevent the performance of the system from deterioration, and it can be applied to TDD and FDD LTE systems simultaneously.
