Wireless communication device, wireless communication terminal, and automatic repeat request control method

摘要

A wireless communication device used in a communication system that utilizes a coordinated multiple-point technique has a determination section that determines another wireless communication device which performs coordinated multiple-point with respect to a wireless communication terminal; an allocation determination section that determines for a predetermined number of sub-frames a proportion of multiple-data-transmission automatic repeat request control to identical-data-transmission automatic repeat request control; an automatic repeat request control section that performs multiple-data-transmission automatic repeat request control; and an automatic repeat request control section that performs identical-data-transmission automatic repeat request control.

1. A wireless communication device used in a communication system configured to utilize a coordinated multiple-point technique, the device comprising:
a coordinated multiple-point base station determination section configured to determine another wireless communication device which performs, together with a wireless communication device of interest, multiple-point coordinate with respect to a wireless communication terminal; an allocation determination section configured to determine for a predetermined number of sub-frames a proportion of multiple-data-transmission automatic repeat request control to identical-data-transmission automatic repeat request control; a first automatic repeat request control section configured to perform the multiple-data-transmission automatic repeat request control; a second automatic repeat request control section configured to perform the identical-data-transmission automatic repeat request control; and a transmission delay time calculation section configured to calculate a transmission delay time existing between the wireless communication device of interest and the other wireless communication device, wherein the allocation determination section is further configured to:
determine from the transmission delay time an allocation showing a proportion of multiple-data-transmission automatic repeat request control to identical-data-transmission automatic repeat request control for the predetermined number of sub-frames, anddetermine the allocation such that the proportion of identical-data-transmission automatic repeat request control increases when the transmission delay time is greater than a predetermined threshold and that the proportion of multiple-data-transmission automatic repeat request control increases when the transmission delay time is less than the predetermined threshold.
