1. A method for transceiving audio data by using Bluetooth low energy in a wireless communication system supporting Bluetooth communication by a first device, the method comprising:
- establishing at least one isochronous channel for transmitting isochronous data with at least one second device by setting an anchor point representing a time at which new information is transmitted;
transmitting the audio data to the at least one second device through at least one established isochronous channel during a first interval starting from the anchor point;
allocating to the at least one second device a response transmission time slot in which a response associated with whether to receive the audio data can be received from the at least one second device; and
receiving the response associated with the reception of the audio data from the at least one second device through the allocated response transmission time slot,wherein the first interval includes at least one second interval in which initial transmissions of the audio data and retransmission of the audio data occur,wherein the initial transmission of the audio data occurs at the anchor point of the first interval, andwherein the response transmission time slot is allocated for each of the at least one second device.

16. A first device for transceiving audio data by using Bluetooth low energy in a wireless communication system supporting Bluetooth communication, the first device comprising:
-
a transceiver; and a processor functionally connected with the transceiver, wherein the processor; establishes at least one isochronous channel for transmitting the audio data with at least one second device by setting an anchor point representing a time at which new information is transmitted, controls the transceiver to transmit the audio data to the at least one second device through at least one established isochronous channel during a first interval starting from the anchor point, allocates to the at least one second device a response transmission time slot in which a response associated with whether to receive the audio data can be received from the at least one second device, and controls the transceiver to receive the response associated with the reception of the audio data from the at least one second device through the allocated response transmission time slot, wherein the first interval includes at least one second interval in which initial transmissions of the audio data and retransmission of the audio data occur, wherein the initial transmission of the audio data occurs at the anchor point of the first interval, and wherein the response transmission time slot is allocated for each of the at least one second device.
