Abstract
In a first aspect, a communication control method is used in a cellular communication system. The communication control method includes configuring, by a donor node including a first relay node and a second relay node being a parent node of the first relay node, the first relay node using correspondence information representing a correspondence relationship between a hop count of a logical channel (LCH) and a logical channel group (LCG), the first relay node and the second relay node being subordinate to the donor node. The communication control method includes transmitting, by the first relay node, a buffer status report (BSR) to the second relay node, based on the correspondence information. The communication control method further includes transmitting, by the second relay node, an uplink grant (UL grant) to the first relay node, based on the correspondence information and the buffer status report.
