METHOD AND APPARATUS FOR TRANSMITTING DOWNLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

Provided are a method and an apparatus for transmitting downlink control information in a wireless communication system configured with a plurality of serving cells. The method generates downlink control information scheduling frequency division duplex (FDD) cells by means of FDD frames (DCI_FDD) and downlink control information scheduling time division duplex (TDD) cells by means of TDD frames (DCI_TDD), and transmits the DCI_FDD and the DCI_TDD, wherein parts of the fields of DCI_FDD and DCI_TDD are generated to have equal bit sizes, and if the FDD or TDD cell is used exclusively, then said parts of the fields in the FDD and TDD cells have mutually different bit sizes.

主权项

1. A method of transmitting downlink control information (DCI) in a wireless communication system in which a plurality of serving cells are configured, the method comprising:
generating DCI for scheduling frequency division duplex (FDD) cells using FDD frames (DCI_FDD) and DCI for scheduling time division duplex (TDD) cells using TDD frames (DCI_TDD), and transmitting the DCI_FDD and the DCI_TDD, wherein some fields of the DCI_FDD and DCI_TDD are generated to have the same bit size, and if the FDD or TDD cell is used exclusively, the some fields are fields having different bit sizes in the FDD cell and the TDD cell.
