1. An operation method of a first communication node in a wireless local area network (LAN) system, the operation method comprising:
generating a first data frame including first add block acknowledgment (ADDBA) information;
transmitting the first data frame to a second communication node;
receiving, from the second communication node, a first block acknowledgment (BA) including second ADDBA information generated by the second communication node in response to the first data frame;
transmitting, to the second communication node, a second data frame not including the first ADDBA information in a same BA session as the first data frame; and
receiving, from the second communication node, a second BA not including the second ADDBA information in response to the second data frame,
wherein a transmission/reception operation of the first data frame is performed without a BA agreement operation between the first communication node and the second communication node.
