Abstract
An operation method of a first communication node in a wireless communication network includes steps of: transmitting, to a plurality of communication nodes, a first frame having configuration information of a data transmission interval including at least one frame transmission interval; and receiving second data frames from at least one of the communication nodes, among the plurality of communication nodes, during the data transmission interval. The first frame may include: identifiers indicating the plurality of communication nodes; and information for configuring a network allocation vector (NAV) for communication nodes excluding the plurality of communication nodes.

An operation method of a first communication node in a wireless local area network (LAN) communication system, the operation method comprising:
- transmitting a first frame for setting a first network allocation vector (NAV);
- transmitting a second frame for setting a second NAV within a transmission opportunity (TXOP) indicated by the first NAV;
- and
- in response to the second frame, receiving a third frame from at least one of second communication node(s) indicated by the second frame within a TXOP indicated by the second NAV.
An operation method of a first communication node in a wireless local area network (LAN) communication system, the operation method comprising:
- transmitting a first frame for setting a first network allocation vector (NAV);
- and
- transmitting a second frame for setting a second NAV within a transmission opportunity (TXOP) indicated by the first NAV,
- wherein at least one communication node of second communication node(s) indicated by the second frame transmits a third frame to a third communication other than the first communication node within a TXOP indicated by the second NAV.
An operation method of a second communication node in a wireless local area network (LAN) communication system, the operation method comprising:
- receiving, from a first communication node, a first frame for setting a first network allocation vector (NAV), and setting the first NAV;
- receiving, from the first communication node, a second frame for setting a second NAV within a transmission opportunity (TXOP) indicated by the first NAV;
- and
- in response to determining that the second frame indicates the second communication node, transmitting a third frame to the first communication node or a third communication node other than the first communication node within a TXOP indicated by the second NAV.
