Abstract
The invention claims a method for repeatedly sending the MTC terminal and receive a random access preamble set when a random access repeat level preamble and determining a transmission power for each random access preamble method and apparatus to improve the limited coverage transceiving performance of the random access preamble of the MTC terminal. In addition the invention claims a method and apparatus for when located in the coverage area of a general terminal with improved coverage area in the terminal repeatedly sends a random access preamble for controlling the transmission power of the random access preamble. When the terminals through a plurality of uplink subframe to repeat transmission of PRACH the terminal can determine repetition sending times of PRACH determining transmission power of the PRACH based on repeated sending times of PRACH and PRACH by aiming at the determined transmission power to send the PRACH.
The present invention provides a method and a device for setting a repetition level of a random access preamble and determining transmission power for each random access preamble when a random access preamble for an MTC terminal is repetitively transmitted and received to increase the transmission and reception performance of a random access preamble for a coverage-restricted MTC terminal. In addition the present invention provides a method and a device for controlling transmission power for a random access preamble when a terminal located in improved coverage compared to the coverage for a general terminal repetitively transmits the random access preamble. When the terminal repetitively transmits a PRACH through a plurality of uplink subframes the terminal can determine the number of repetitive transmissions of the PRACH determine transmission power for the PRACH on the basis of the number of repetitive transmissions of the PRACH and transmit the PRACH at the transmission power determined for the PRACH.
