Apparatus and method for controlling receiving data

A method of operating a first electronic device in a wireless communication system, the method comprising:

• determining, by at least one processor, whether to perform a partial decoding or a normal decoding based on a channel quality;
• if it is determined to perform the partial decoding,
• decoding, by the at least one processor, partial data received by a transceiver from a second electronic device during a part of one transmission time interval (TTI);
• when the decoding of the partial data succeeds, performing, by the at least one processor, at least one complementary decoding until a decoding success count reaches a decoding threshold;
• and
• when the decoding success count reaches the decoding threshold, outputting, by the at least one processor, a decoding result for the at least one complementary decoding;
• and
• if it is determined to perform the normal decoding, decoding, by the at least one processor, all data of the one TTI and outputting a decoding result for all of the data,
• wherein one of the at least one complementary decoding comprises:
• a decoding of data comprising:
• previous data for which a previous decoding was performed;
• and
• additional data received by the transceiver during an additional part of the one TTI, after the previous data.
