Title:
RANDOM ACCESS WIRELESS COMMUNICATION SYSTEM AND RANDOM ACCESS WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/149161
Kind Code:
A1
Abstract:
A random access wireless communication system that uses random access to perform downlink communication from a wireless base station to wireless terminals. The wireless terminals include at least one low-delay terminal that is required to have low delay and at least one not-low-delay terminal that is not required to have low delay. The low-delay terminal(s) and the not-low-delay terminal(s) are distinguished by SSID. The random access wireless communication system comprises: a terminal assignment control means that distinguishes the low-delay terminal(s) and the not-low-delay terminal(s) by SSID and uniformly allocates each of the low-delay terminal(s) and the not-low-delay terminals to a plurality of communication channels; and a random access control means that, for each communication channel, performs priority control of the low-delay terminal(s) and the not-low-delay terminal(s) such that downlink communication at the low-delay terminal(s) satisfies a prescribed delay time.
