METHOD AND APPARATUS FOR TRANSMITTING DOWNLINK CONTROL INFORMATION

摘要

Disclosed is a method for transmitting downlink control information. The method comprises: a base station determining a time domain position and a frequency domain position of an enhanced search space bearing downlink control information, and sending the downlink control information on the time domain position and the frequency domain position. The present invention further discloses an apparatus for transmitting downlink control information. By means of the solutions in the present invention, the problem that a search space of a PDCCH area cannot be used to transmit downlink control information is solved by transmitting the downlink control information through an enhanced search space when an NCT is independently operated and a low-cost terminal is accessing a large bandwidth system.
