Abstract
Official abstract text for this publication.
Disclosed are a method and an apparatus for transmitting data in a wireless LAN system. The method for transmitting data comprises the steps of: generating a discontinuation request frame for requesting discontinuation of transmitting a data frame from a master-access point to a relay device; and transmitting the discontinuation request frame to the master-access point. As a result, the occurrence of a buffer overflow in the relay device can be prevented.
First claim
Opening claim text (preview).
1 . A method for data transmission being performed by a relay device for relaying data transmitted between a master access point and an end terminal, comprising: generating a suspend request frame that requests suspension of transmission of a data frame from the master access point to the relay device; and transmitting the suspend request frame to the master access point. 2 . The method of claim 1 , wherein the suspend request frame is an acknowledge (ACK) frame that is a response to a data frame received from the master access point, and the ACK frame includes information indicating that the relay device is operated in a doze mode. 3 . The method of claim 1 , wherein the suspend request frame is a null data frame that includes information indicating that the relay device is operated in a doze mode. 4 . The method of claim 1 , wherein the suspend request frame includes information about a suspend duration during which transmission of a data frame is suspended. 5 . A method for data transmission being performed by a relay device for relaying data transmitted between a master access point and an end terminal, comprising: generating a resume request frame that requests resumption of transmission of a data frame from the master access point to the relay device; and transmitting the resume request frame to the master access point. 6 . The method of claim 5 , further comprising: receiving a data frame, as a response to the resume-request frame, from the master access point; and transmitting an acknowledge (ACK) frame, as a response to the data frame, to the master access point. 7 . The method of claim 5 , wherein the resume request frame is a power save (PS)-Poll frame or a trigger frame indicating that the relay device is operated in an awake mode. 8 . The method of claim 5 , wherein the resume request frame is a null data frame that includes information indicating that the relay device is operated in an awake mode. 9 . The method of claim 5 , wherein transmitting the resume request frame to the master access point is configured to transmit the resume request frame to the master access point when it is determined that data to be transmitted to the relay device is buffered in the master access point, based on a beacon frame received from the master access point.
