Method and apparatus for transmitting data for wireless communication
The present disclosure relates to a communication technique for combining an IoT technology with a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security and safety-related services, and the like) on the basis of 5G communication technologies and IoT-related technologies. A method for a terminal in a wireless communication system, according to the present disclosure, comprises the steps of: receiving a control signal; determining, from the control signal, a resource to which data can be mapped and then transmitted/received; and receiving data according to the determined resource for the data.
1. A method performed by a terminal in a communication system, the method comprising:
receiving first rate matching resource information and second rate matching resource information via higher layer signaling, the first rate matching resource information and the second rate matching resource information being associated with a cell-specific reference signal (CRS);
in case that a first scheme for a rate matching is performed based on information indicating the first scheme for the rate matching is to be performed being received from a base station:
receiving a first physical downlink shared channel (PDSCH) or a second PDSCH,
wherein a resource indicated by the first rate matching resource information is not used to receive the first PDSCH, and a resource indicated by the second rate matching resource information is not used to receive the second PDSCH; and
in case that a second scheme of the rate matching is to be performed:
receiving a PDSCH, wherein the resources indicated by the first rate matching resource information and the second rate matching resource information are not used to receive the PDSCH.
2. The method of claim 1 , wherein the first PDSCH is associated with an index corresponding to a first transmission and reception point (TRP) configured via higher layer signaling, and the second PDSCH is associated with an index corresponding to a second TRP configured via higher layer signaling.

5. A method performed by a base station in a communication system, the method comprising:
transmitting first rate matching resource information and second rate matching resource information via higher layer signaling, the first rate matching resource information and the second rate matching resource information being associated with a cell-specific reference signal (CRS);
in case that information indicating a first scheme for a rate matching is to be performed is transmitted and the first scheme for the rate matching is performed:
transmitting a first physical downlink shared channel (PDSCH) in a resource excluding the resource indicated by the first rate matching resource information; or
transmitting a second PDSCH in a resource excluding the resource indicated by the second rate matching resource information; and
in case that a second scheme for the rate matching is to be performed:
transmitting a PDSCH in a resource excluding the resources indicated by the first rate matching resource information and the second rate matching resource information.
6. The method of claim 5 , wherein the first PDSCH is associated with an index corresponding to a first transmission and reception point (TRP) configured via higher layer signaling, and the second PDSCH is associated with an index corresponding to a second TRP configured via higher layer signaling.
7. The method of claim 5 , wherein the first rate matching resource information and the second rate matching resource information includes at least one of a CRS v-shift value, a number of CRS antenna ports, or frequency location information.
8. The method of claim 5 , wherein the information indicating the first scheme for the rate matching is to be performed is transmitted via higher layer signaling.
9. A terminal in a communication system, the terminal comprising:
a transceiver; and
a controller configured to:
receive first rate matching resource information and second rate matching resource information via higher layer signaling, the first rate matching resource information and the second rate matching resource information being associated with a cell-specific reference signal (CRS), and
in case that a first scheme for a rate matching is performed based on information indicating the first scheme for the rate matching is to be performed being received from a base station:
receive a first physical downlink shared channel (PDSCH) or a second PDSCH, wherein a resource indicated by the first rate matching resource information is not used to receive the first PDSCH, and a resource indicated by the second rate matching resource information is not used to receive the second PDSCH, and
in case that a second scheme of the rate matching is to be performed:
receive a PDSCH, wherein the resources indicated by the first rate matching resource information and the second rate matching resource information are not used to receive the PDSCH.
10. The terminal of claim 9 , wherein the first PDSCH is associated with an index corresponding to a first transmission and reception point (TRP) configured via higher layer signaling, and the second PDSCH is associated with an index corresponding to a second TRP configured via higher layer signaling.
11. The terminal of claim 9 , wherein the first rate matching resource information and the second rate matching resource information includes at least one of a CRS v-shift value, a number of CRS antenna ports, or frequency location information.
12. The terminal of claim 9 , wherein the information indicating the first scheme for the rate matching is to be performed is received via higher layer signaling.
13. A base station in a communication system, the base station comprising:
a transceiver; and
a controller configured to:
transmit first rate matching resource information and second rate matching resource information via higher layer signaling, the first rate matching resource information and the second rate matching resource information being associated with a cell-specific reference signal (CRS),
