Japanese Patent JP6313905
Kind Code:
B2
Abstract:
Techniques for controlling a transport block size to implement HARQ sharing are disclosed. One aspect of the present invention relates to a base station, comprising: a cell management unit configured to manage cells for radio communication with user equipment; and a MAC processing unit configured to control a retransmission operation via multiple cells by using HARQ sharing for managing one or more HARQ processes as a common HARQ process, wherein the cell management unit acquires communication quality of multiple HARQ sharing applied cells, and the MAC processing unit controls to activate transmission via the multiple cells with a minimum transmission data size among transmission data sizes corresponding to the acquired communication quality of the respective cells.
