Title:
DEVICE FOR TRANSMITTING DATA IN WIRELESS AV SYSTEM AND DEVICE FOR RECEIVING DATA IN WIRELESS AV SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/262740
Kind Code:
A1
Abstract:
The present invention relates to a device for transmitting data in a wireless AV system, and a device for receiving data in a wireless AV system. The present specification discloses a device comprising: a communication unit configured to receive, from an initiator, a forward direction data frame and reverse direction grant information, instructing that reverse direction transmission be allowed, within a transmission opportunity acquired by the initiator, generate and transmit to the initiator, a block ACK frame pertaining to the forward direction data frame, and buffer a reverse direction data frame to be transmitted to the initiator; and a processor connected to the communication unit and configured to acquire AV data from the forward direction data frame. When a reverse direction grant is activated in a wireless AV system that operates a reverse direction grant protocol, the present invention has the effect of enabling retransmission of the forward direction data frame within a valid transmission time even when transmission of the forward direction data frame fails, and also being able to achieve transmission of the reverse direction data frame.
