1. A communication control method executed in a relay apparatus comprising a base station function processor connecting wirelessly to a lower apparatus, and a user equipment function processor connecting wirelessly to an upper apparatus, the relay apparatus relaying upstream data from the lower apparatus to the upper apparatus, the communication control method comprising:
transmitting, to the upper apparatus, a first buffer state report indicating an amount of untransmitted upstream data of the relay apparatus; and
transmitting, to the upper apparatus, a second buffer state report indicating at least an amount of untransmitted upstream data of the lower apparatus, wherein
a trigger condition transmitting the second buffer state report is different from a trigger condition transmitting the first buffer state report, wherein
the communication control method further comprises:
receiving a third buffer state report from the lower apparatus, the third buffer state report indicating an amount of the untransmitted upstream data of the lower apparatus; and
receiving a fourth buffer state report different from the third buffer state report from the lower apparatus, the fourth buffer state report indicating an amount of untransmitted upstream data of a lower apparatus of the lower apparatus, wherein
the first buffer state report is based on the amount of the untransmitted upstream data indicated by the third buffer state report, out of the third buffer state report and the fourth buffer state report.
