METHOD AND APPARATUS FOR TRANSMITTING DOWNLINK CONTROL INFORMATION FOR RESOURCE ALLOCATION IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for transmitting Downlink Control Information (DCI) by a base station in a wireless communication system, the method comprising the steps of:
- generating DCI including at least one of a data resource allocation indicator, a data format indicator for at least one Transport Block (TB), and a DeModulation Reference Signal (DMRS) resource allocation indicator corresponding to the at least one TB; and
sending the DCI to a terminal,wherein the DMRS resource allocation indicator includes a rank pattern for the at least one TB, an allocated scrambling code type, and DMRS port information.

Abstract
A method and apparatus for transmitting and receiving Downlink Control Information (DCI) in a wireless communication system. A method for transmitting DCI by a base station includes generating DCI including at least one of a data resource allocation indicator, a data format indicator for at least one Transport Block (TB), and a DeModulation Reference Signal (DMRS) resource allocation indicator corresponding to the at least one TB; and sending the DCI to a terminal. The DMRS resource allocation indicator includes a rank pattern for the at least one TB, an allocated scrambling code type, and DMRS port information.
