METHOD AND APPARATUS FOR TRANSMITTING BACKHAUL LINK INFORMATION

摘要

Disclosed are a method and an apparatus for transmitting backhaul link information. A method for acquiring backhaul link state information for a station (STA) may comprise the steps of: an STA transmitting, to an access point (AP), a generic advertisement service (GAS) request frame requesting a backhaul link state information of the AP; the STA receiving, as a response to the GAS request frame, a GAS response frame comprising backhaul link state information, wherein the GAS request frame is a frame transmitted by an STA, before an authentication or an association procedure and after a scanning procedure of the AP, to request availability-related information of a network to be accessed by the STA, and the backhaul link state information can comprise information regarding the load of a backhaul link linking network apparatuses other the AP and the STA.

主权项

1. A method for obtaining backhaul link state information by a station (STA), the method comprising:
transmitting, by the STA, a generic advertisement service (GAS) request frame to request the backhaul link state information of a access point (AP) to the AP; and receiving, by the STA, a GAS response frame including the backhaul link state information in response to the GAS request frame, wherein the GAS request frame is a frame that is transmitted before the STA performs an authentication procedure or an association procedure after a scanning procedure for the AP to request information related to availability of a network which the STA is to access, and wherein the backhaul link state information includes information on a load of a backhaul link connecting other network devices than the AP and the STA.
