Method for transmitting and receiving control channel in wireless communication system

摘要

Provided is a communication system that transmits a control channel using a downlink. The communication system may transmit, to the terminal, transmission information of uplink allocation information that indicates whether uplink allocation information is transmitted using a downlink, and the terminal may determine whether the uplink allocation information is included in a downlink frame, based on the transmission information of uplink allocation information. The base station may transmit, to the terminal, information associated with a resource which has a possibility of being used for transmission of a physical downlink control channel (PDCCH), and the terminal may decode the PDCCH in the resource which has a possibility of being used for transmission of the PDCCH.

1. A method of transmitting control information, the method comprising:
configuring a resource allocation scheme identifier indicating a resource allocation type; configuring a resource allocation indicator indicating allocation information on resource for transmission of a downlink control channel according to the resource allocation type indicated by the resource allocation scheme identifier; and transmitting to a receiver the resource allocation scheme identifier and the resource allocation indicator by upper layer signaling, wherein the resource allocation scheme identifier distinguishes 4 or more types including resource allocation type 0, resource allocation type 1, resource allocation type 2 with localized virtual resource blocks, and resource allocation type 2 with distributed virtual resource blocks, and wherein the resource allocation scheme identifier and the resource allocation indicator are included in RRC (Radio Resource Control) signaling message transmitted from the base station.
