Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA IN COMMUNICATION SYSTEM SUPPORTING MULTIPLE LINKS
Document Type and Number:
WIPO Patent Application WO/2021/206378
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for transmitting and receiving data in a communication system supporting multiple links. A method for operation of a first device comprises the steps of: transmitting, in a first link from among multiple links, a first RTS frame to a second device; receiving, from the second device in the first link, a first CTS frame that is a response to the first RTS frame; when the first CTS frame is received, transmitting, in the first link, a first data frame to the second device; and transmitting, in a second link during transmission of the first data frame, a second RTS frame to the second device.
