Method and apparatus for transmitting and receiving downlink data corresponding to resource allocation information and indicator in mobile communication system

A method performed by a terminal in a wireless communication system, the method comprising:

• receiving information on a plurality of control channel resources on radio resource control (RRC) signaling, the information on the plurality of control channel resources indicating a specific pattern on a frequency domain and on a time domain of each control channel resource;
• receiving, from a base station, downlink control information (DCI), the DCI including resource allocation information indicating a resource for downlink data and an indicator for a rate matching of the downlink data, wherein the indicator indicates whether a control channel resource which overlaps with the resource for the downlink data is unavailable for the downlink data, and wherein the control channel resource is one of the plurality of control channel resources and is for another terminal;
• and
• receiving the downlink data based on the resource allocation information and the indicator,
• wherein in case that the indicator indicates that the control channel resource is unavailable for the downlink data, the downlink data is rate-matched not to be mapped on the control channel resource.

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• transmit information on a plurality of control channel resources on radio resource control (RRC) signaling, the information on the plurality of control channel resources indicating a specific pattern on a frequency domain and on a time domain of each control channel resource,
• transmit, to a terminal, downlink control information (DCI), the DCI including resource allocation information indicating a resource for downlink data and an indicator for a rate matching of the downlink data, wherein the indicator indicates whether a control channel resource which overlaps with the resource for the downlink data is unavailable for the downlink data, and wherein the control channel resource is one of the plurality of control channel resources and is for another terminal, and
• transmit the downlink data corresponding to the resource allocation information and the indicator,
• wherein in case that the indicator indicates that the control channel resource is unavailable for the downlink data, the downlink data is rate-matched not to be mapped on the control channel resource.
