Document Type and Number:
Japanese Patent JP6836479
Kind Code:
B2
Abstract:
To perform radio transmission in parallel without lowering transmission efficiency even in an environment in which radio communication quality changes in a short period.SOLUTION: A radio transmission device for parallel transmission is configured to: generate a plurality of division transmit data by dividing, by a division number, transmit data to be divided by the division number larger than the number of a plurality of radio transmission lines included in parallel radio transmission lines, the transmit data being duplicated and allocated to the respective radio transmission lines; array turns of transmission of division transmit data for the respective radio transmission lines so that a probability that transmission of division transmit data of each radio transmission line overlaps with that of another radio transmission line becomes lower; store the division transmit data in a transmit data storage part by the radio transmission lines according to the arrayed turns; gather information to be used to determine whether to change division transmit data to be transmitted next; and read out and transmit, by radio transmission parts as many as radio transmission lines, division transmit data by the radio transmission lines, and then perform, when division transmit data to be transmitted next is changed, transmission according to the change.SELECTED DRAWING: Figure 1
