Title:
DELAY TIME GUARANTEED WIRELESS COMMUNICATION TERMINAL AND DELAY TIME GUARANTEED WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/176568
Kind Code:
A1
Abstract:
[Problem] To provide a delay time guaranteed wireless communication terminal that guarantees delay time in a wireless communication system. [Solution] Provided is a delay time guaranteed wireless communication terminal, which is one of a plurality of slave terminals that wirelessly communicate with a master terminal in a wireless communication system, the delay time guaranteed wireless communication terminal being provided with: a synchronization information transmission/reception unit that wirelessly transmits/receives, via a first communication band, synchronization information as information for synchronization with the master terminal and other slave terminals; a synchronization processing unit that performs synchronization with each of other slave terminals at intervals of a first predetermined time and controls a timing of transmitting general information other than the synchronization information by arbitration points provided at every second predetermined time; and a general information transmission/reception unit that detects that other terminals have not transmitted the general information and then wirelessly transmits the general information via a second communication band, wherein the synchronization processing unit refers to results of detection of the general information performed by other slave terminals using the general information transmission/reception unit to determine whether or not to transmit the general information, and the general information transmission/reception unit follows an instruction from the synchronization processing unit.
