Abstract
A method for a user equipment sending an uplink resource scheduling request in a long term evolution mobile communication system and the user equipment thereof are provided. The present invention relates to a technique for the user equipment sending the uplink resource scheduling request in a long term evolution system for reducing the user data transmission delay. The embodiments of the present invention set the minimum alternative option of the scheduling request transmission cycle configuration parameter as 2 ms or 1 ms that is to say add 2 ms or 1 ms or 2 ms and 1 ms to the alternative option of the scheduling request transmission cycle configuration parameter therefore improving the flexibility of the whole system in the scheduling request transmission cycle configuration. When the data delay is required to be less the user data transmission delay can be reduced by using the 2 ms or 1 ms scheduling request transmission cycle configuration to the delay requirement of 10 ms as close as possible.
