Patent Searching and Data


Title:
COMMUNICATION DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/152973
Kind Code:
A1
Abstract:
Provided is a communication device that achieves data sharing and cooperative transmission of shared data. The communication device that operates as an access point comprises: a communication unit which transmits and receives wireless signals; and a control unit which controls communication operations performed by the communication unit, including a communication operation for sharing data to be simultaneously transmitted to one communication terminal between adjacent access points, and a communication operation for recognizing that the sharing of the data is completed. When the shared data is transmitted at the same time by the adjacent access points, the control unit performs control so as to multiplex the shared data with a transmission stream addressed to another communication device and transmit the transmission stream as a multi-user multiplexed stream.
