Method and apparatus for transmitting and receiving data in wireless communication system

A method for a base station (BS), the method comprising:

• receiving a signal having a signal strength that is higher than a threshold value;
• and
• in case that a decoding of the signal fails:
• identifying whether a resource on which the signal has been received is included in an overlap region in which a first resource region dynamically allocated by control information and a second resource region predetermined by configuration information overlap;
• identifying, based on the resource being included in the overlap region, an amount of resources in the overlap region;
• storing the received signal in a buffer based on the amount of resources in the overlap region not exceeding a threshold amount of resources;
• and
• skipping storing of the received signal in the buffer based on the amount of resources in the overlap region exceeding the threshold amount of resources.

A base station (BS) comprising:

• a transceiver;
• and
• a controller configured to:
• receive a signal having a signal strength that is higher than a threshold value,
• identify that decoding of the received signal fails,
• identify that resources on which the received signal has been received are included in an overlapped portion in which a first resource dynamically allocated by control information and a second resource predetermined by configuration information overlap,
• identify, based on the resources being included in the overlapped portion, an amount of the resources in the overlapped portion;
• skip storage, in a buffer, of the received signal that failed decoding, based on the amount of the resources in the overlapped portion exceeding a threshold amount of resources, and
• request retransmission of the received signal on a resource excluding the overlapped portion.
