Abstract  Abstract

The invention claims a service from a plurality of cells in a particular cell of random access of transmission in using carrier aggregation technology of mobile communication system and a high efficiency transmitting in the other cell other than random access of uplink channel of method. Specifically the terminal to the base station uplink channel of method comprises step of confirming for first carrier of a random access code in subframe comprises of having a different from the first carrier of uplink link time sequence of the second carrier of uplink channel if so confirming transmitting the random access preamble code of power and transmits uplink channel of the power of and exceeds the maximum transmission power of the terminal and if it is over then sending a random access preamble prior to uplink channel. In addition for uplink channel to the base station of the terminal comprising: a transmitter/receiver for to/from the base station transmitting/receiving signal and a control unit for confirming the first carrier wave of transmitting subframe of a random access preamble included in a different from the first carrier of uplink link time sequence of the second carrier of uplink channel and if so confirming transmitting the random access preamble code of power and transmits uplink channel of the power of and exceeds the maximum transmission power of the terminal and if the control to the uplink link transmitting priority before sending the random access preamble.

The present invention relates to a transmission of a random access in a specific cell from a plurality of serving cells in a mobile communication system using a carrier aggregation technology and a method for efficiently transmitting uplink channels other than the random access in another cell. In particular the method for a terminal to transmit an uplink channel to a base station comprises the steps of: confirming whether an uplink channel for a second carrier having an uplink timing different from a first carrier is included in a subframe transmitting a random access preamble for the first carrier; if included confirming whether the sum of the electric power required for the transmission of the random access preamble and the electric power required for the transmission of the uplink channel exceeds the maximum transmission electric power of the terminal; and if exceeding transmitting the random access preamble preferentially before the uplink channel. In addition the terminal for transmitting an uplink channel to a base station comprises: a transmitter/receiver for transmitting/receiving a signal to/from the base station; and a control unit for confirming whether the uplink channel for a second carrier having an uplink timing different from a first carrier is included in a subframe for transmitting a random access preamble for the first carrier and if included confirming whether the sum of the electric power required for transmitting the random access preamble and the electric power required for transmitting the uplink channel exceeds the maximum transmission electric power of the terminal and if exceeding controlling the transmission so that the random access preamble is preferentially transmitted before the uplink channel.
