MOBILE COMMUNICATION METHOD, WIRELESS BASE STATION, AND MOBILE STATION

摘要

In order to avoid the development of an up data transmission delay when an 'Inter site CA' is implemented, a mobile communication method according to the present invention includes: a step of a mobile station (UE) transmitting an SR to a wireless base station (eNB#1) by using PUCCH-SR; a step of the wireless base station (eNB#1) notifying the mobile station (UE) of a 'UL grant'; a step of the mobile station (UE) transmitting, by using a PUSCH designated by the 'UL grant' a BSR in a bearer (#B/LCH#B) to the wireless base station (eNB#1); a step of the wireless base station (eNB#1) notifying a wireless base station (eNB#10) of a buffer retained amount in the bearer (#B/LCH#B); and a step of the wireless base station (eNB#10) allocating, in accordance with the reception of the buffer retained amount, an up data transmission resource to the mobile station (UE).
