Method for sharing multilink in next-generation wireless LAN
A method for sharing a multilink in a next-generation wireless LAN is disclosed. An operation method of a first communication node comprises the steps of: setting a transmission interval; communicating with a second communication node by using a first link and a second link in the transmission interval; sharing the transmission interval with a third communication node; and communicating with the second communication node by using the first link in the transmission interval.
1 . An operation method of an access point (AP) in a communication system, the operation method comprising:
configuring a transmission opportunity (TXOP);
generating a trigger frame indicating TXOP sharing;
transmitting the trigger frame to a first station (STA) which is a target of the TXOP sharing;
receiving a response frame for the trigger frame from the first STA; and
performing a transmission and reception operation between the AP and the first STA at predefined time intervals in a TXOP sharing time period allocated by the trigger frame without a channel contention,
wherein the TXOP sharing time period exists in the TXOP, and the trigger frame includes a first field indicating an identifier of the first STA being the target of the TXOP sharing, a second field indicating the TXOP sharing time period, a fourth field indicating whether the TXOP sharing is allowed, and a resource unit (RU) allocation field indicating a frequency resource allocated to the first STA.
2 . The operation method according to claim 1 , wherein a second data frame of the first STA is transmitted to the AP or a second STA in the TXOP sharing time period.
3 . The operation method according to claim 1 , wherein the trigger frame further includes a third field indicating a link in which the TXOP is shared.
4 . An operation method of a first station (STA) in a communication system, the operation method comprising:
receiving a trigger frame indicating transmission opportunity (TXOP) sharing from an access point (AP);
identifying a TXOP sharing time period allocated by the trigger frame;
transmitting a response frame for the trigger frame to the AP; and
transmitting a first data frame without a channel contention in the TXOP sharing time period belonging to a TXOP,
wherein the TXOP is configured by the AP, the TXOP sharing time period exists in the TXOP, the first station is a target of the TXOP sharing, and the trigger frame includes a first field indicating an identifier of the first STA being the target of the TXOP sharing, a second field indicating the TXOP sharing time period, a fourth field indicating whether the TXOP sharing is allowed, and a resource unit (RU) allocation field indicating a frequency resource allocated to the first STA.
5 . The operation method according to claim 4 , wherein the first data frame of the first STA is transmitted to the AP or a second STA in the TXOP sharing time period.
6 . The operation method according to claim 4 , wherein the trigger frame further includes a third field indicating a link in which the TXOP is shared.
7 . An operation method of an access point (AP) in a communication system, the operation method comprising:
configuring a transmission opportunity (TXOP);
generating a trigger frame indicating TXOP sharing; and
transmitting the trigger frame to a first station (STA) which is a target of the TXOP sharing; and
receiving a response frame for the trigger frame from the first STA,
wherein a TXOP sharing time period exists in the TXOP and the trigger frame includes a first field indicating an identifier of the first STA being the target of the TXOP sharing, a second field indicating the TXOP sharing time period, a fourth field indicating whether the TXOP sharing is allowed, and a resource unit (RU) allocation field indicating a frequency resource allocated to the first STA.
8 . The operation method according to claim 7 , wherein the trigger frame further includes a third field indicating a link in which the TXOP is shared.
