Title: RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD
Abstract:
Provided is a radio communication system that, in a case of performing a downlink communication from a radio base station to a radio terminal on the basis of a random access mode, performs the downlink communication on the basis of a transmission right acquired by the radio base station (TXOP access) or of a transmission right acquired by the radio terminal and then transferred to the radio base station (RXOP access), wherein the radio base station comprises a control means that, for a transmission buffer for sequentially storing data frames to be transmitted for each of a plurality of radio terminals, performs, in accordance with a transmission state of a data frame addressed to a radio terminal A using the RXOP access, a process of lowering the priority level of a data frame addressed to the radio terminal A and waiting for transmission using the TXOP access.
