Abstract
A method and a device are operable utilizing a wireless local area network (LAN) for low latency communication. A method of operating a station (STA) multi-link device (MLD) in the wireless LAN includes steps of: receiving, by a processor of the station, from a first access point (AP) in a first link, a first frame including information about a first restricted target wake time (rTWT) service period (SP) configured in the first link and information about a second rTWT SP configured in a second link; and receiving, by the processor, from a second AP, a data frame in the second rTWT SP of the second link if reception of the data frame in the first rTWT SP of the first link fails.
Claims20
A method of operating a station (STA) multi-link device (MLD) in a wireless local area network (LAN), the method comprising:
- receiving, by a processor of the station, from a first access point (AP) and on a first link, a first frame including information on a first restricted target wake time (rTWT) service period (SP) configured on the first link and information on a second rTWT SP configured on a second link;
- and
- in response to a failure of receiving a data frame in the first rTWT SP on the first link, receiving, by the processor, the data frame from a second AP in the second rTWT SP on the second link.
A method of operating an access point (AP) multi-link device (MLD) in a wireless local area network (LAN), the method comprising:
- transmitting, by a processor of the access point, to a first station (STA) and on a first link, a first frame including information on a first restricted target wake time (rTWT) service period (SP) configured on the first link and information on a second rTWT SP configured on a second link;
- and
- in response to a failure of transmitting a data frame in the first rTWT SP on the first link, transmitting, by the processor, the data frame to a second STA in the second rTWT SP on the second link.
A station (STA) multi-link device (MLD) in a wireless local area network (LAN), comprising a processor, the station comprising:
- receiving, by the processor, from a first access point (AP) and on a first link, a first frame including information on a first restricted target wake time (rTWT) service period (SP) configured on the first link and information on a second rTWT SP configured on a second link;
- and
- in response to a failure of receiving a data frame in the first rTWT SP on the first link, receiving, by the processor, the data frame from a second AP in the second rTWT SP on the second link.
