Abstract:
1. A mobile communication method in accordance with a scheme of previously securing a hardware resource inside a radio base station before the radio base station notifies a mobile station of a value as a scheduling grant, the hardware resource intended to be used in decoding of uplink signals transmitted from the mobile station, the value used by the mobile station to obtain a power allowed for the mobile station to use for uplink user data transmission, the mobile communication method comprising: a step A of causing the radio base station to calculate a data amount of uplink user data transmittable in a unit of time by the mobile station on a basis of an amount of the hardware resource secured by the radio base station for the mobile station; a step B of causing the radio base station to calculate the scheduling grant on a basis of the data amount calculated in the step A; a step C of causing the radio base station to notify the mobile station of the scheduling grant calculated in the step B, via a predetermined notification channel; a step D of causing the radio base station to make a comparison between transmission format identification information received from the mobile station and transmission format identification information based on the data amount calculated in the step A; and a step E of causing the radio base station to retransmit the scheduling grant calculated in the step B, if the radio base station determines, based on a comparison result in the step D, that a data amount indicated by the transmission format identification information received from the mobile station is larger than the data amount calculated in the step A; wherein if the transmission format identification information received from the mobile station is larger than the calculated data amount of uplink user data calculated in step A, the scheduling grant is lowered to a predetermined value, and then the lowered scheduling grant is retransmitted.
