DOWNLINK CONTROL CHANNEL TRANSMITTING METHOD OF TRANSMISSION POINT, TRANSMISSION POINT THEREOF, DOWNLINK CONTROL CHANNEL RECEIVING METHOD OF USER EQUIPMENT, AND USER EQUIPMENT THEREOF

摘要

PURPOSE: A downlink control channel transmission method of a transmission part, the transmission part, a downlink control channel reception method of a reception part and the terminal are provided to prevent transmission of a downlink transmission signal to a number of terminals simultaneously by transmitting a downlink control channel in a sub frame having different offset about each terminal. CONSTITUTION: All sub frame includes a control region(310) for a downlink control channel such as a PDCCH and a data region(320) for a downlink data channel such as a PDSCH. Based on information specified to a mechanical type communication terminal, the mechanical type communication terminal sets up a period and offsets of a sub frame for executing blind decoding on a downlink control channel. Based on the period and offset, a downlink control channel is transmitted to a selected sub frame. The stage of setting up includes a stage of setting up length of a sub frame. The selected sub frame is selected based on the period and offset, and the length. [Reference numerals] (AA,CC) Offset=2; (BB,DD) Length=1; (EE) Period=3
