Multi-link operation mode
In a wireless local area network (WLAN) system, a station (STA) may support a multi-link. The STA may generate a PDDU including operation mode information on whether transmission of a signal and reception of a signal can be performed simultaneously. The STA may transmit the PPDU.
1 . A method in a wireless local area network (WLAN) system, the method comprising:
generating, by an Access Point (AP), a frame including multi-link information,
wherein the multi-link information has a value of one (1) based on Non-Simultaneous Transmit and Receive (NSTR) information related to links of the AP,
wherein the multi-link information has a value of zero (0) based on Simultaneous Transmit and Receive (STR) information related to links of the AP,
wherein the frame further includes a link identifier (ID) field identifying a link; and
transmitting, by the AP, the frame.
2 . The method of claim 1 , wherein the NSTR information is related to links on which signal transmission and signal reception cannot be performed simultaneously.
3 . The method of claim 1 , wherein the STR information is related to links on which signal transmission and signal reception can be performed simultaneously.
4 . An Access Point (AP) in a wireless local area network (WLAN) system, comprising:
a transceiver adapted to transmit and/or receive a wireless signal; and
a processor coupled to the transceiver,
wherein the processor is adapted to:
generate a frame including multi-link information,
wherein the multi-link information has a value of one (1) based on Non-Simultaneous Transmit and Receive (NSTR) information related to links of the AP,
wherein the multi-link information is set to has a value of zero (0) based on Simultaneous Transmit and Receive (STR) information related to links of the AP,
wherein the frame further includes a link identifier (ID) field identifying a link; and
transmit the frame.
5 . The AP of claim 4 , wherein the NSTR information is related to links on which signal transmission and signal reception cannot be performed simultaneously.
6 . The AP of claim 4 , wherein the STR information is related to links on which signal transmission and signal reception can be performed simultaneously.
