Abstract
Proposed are a method and apparatus for performing joint transmission in a wireless LAN system. Specifically, an M-AP transmits a C-RTS frame to first and second S-APs. The M-AP receives, from the first and second S-APs, a CTS frame that is a response to the C-RTS frame. The M-AP performs joint transmission on an STA through the first and second S-APs.
Claims15
A method for performing joint transmission in a wireless LAN system, the method comprising:
- transmitting, by a Master-Access Point (M-AP), a Coordinated-Request To Send (C-RTS) frame to a first Slave-Access Point (S-AP) and a second S-AP;
- receiving, by the M-AP, a Clear To Send (CTS) frame, as a response to the C-RTS frame, to the first and second S-APs;
- and
- performing, by the M-AP, the joint transmission to a station (STA) through the first and second S-APs.
A wireless device being a Master-Access Point (M-AP) performing joint transmission in a wireless LAN system, the M-AP comprising:
- a memory;
- a transceiver;
- and
- a processor being operatively connected to the memory and the transceiver, wherein the processor is configured to:
- transmit a Coordinated-Request To Send (C-RTS) frame to a first Slave-Access Point (S-AP) and a second S-AP,
- receive a Clear To Send (CTS) frame, as a response to the C-RTS frame, from the first and second S-APs, and
- perform the joint transmission to a station (STA) through the first and second S-APs.
A method for receiving a joint frame in a wireless LAN system, the method comprising:
- simultaneously receiving, by a station (STA), a joint frame from first and second Slave-Access Points (S-APs);
- transmitting, by the STA, an ACK or Block ACK (BA) for the joint frame to the first and second S-APs,
- wherein the first and second S-APs exchange a Coordinated-Request To Send (C-RTS) frame and a Clear To Send (CTS) frame to the Master-Access Point (M-AP), and
- wherein the CTS frame is a response to the C-RTS frame.
