Title:
WIRELESS COMMUNICATION SYSTEM, INPUT-SIDE DEVICE, AND OUTPUT-SIDE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/059406
Kind Code:
A1
Abstract:
[Problem] To provide a wireless communication system in which it is possible to transmit data with low delay by suppressing an increase in buffer capacity, while preventing the depletion of data within each buffer. [Solution] A base station 200: uses a relationship in which the sum of the data amount stored in a buffer 131 of a mobile station 100 and the data amount stored in a buffer 241 of the base station 200 is fixed to determine an image encoding rate and a wireless transmission rate on the basis of the wireless transmission path quality measured by a transmission path quality measurement unit 233, and the data amount stored in the buffer 241 of the base station; transmits the determined rates to the mobile station 100; and causes the determined rates to be reflected in the settings of an image encoding unit 121 and a wireless encoding unit 132.
