Embodiment Construction

[0074] (Structure of the mobile communication system according to the first embodiment of the present invention)

[0075] refer to figure 1 , and the configuration of the mobile communication system according to the first embodiment of the present invention will be described. In addition, in this embodiment, an LTE-based mobile communication system is described as an example, but the present invention can also be applied to other mobile communication systems.

[0076] In addition, in the mobile communication system according to the present embodiment, the mobile station UE is configured to transmit uplink data to the radio base station eNB using PUSCH (uplink radio resource) allocated fixedly at a predetermined period starting from the allocation start time.

[0077] That is, in the mobile communication system according to the present embodiment, the mobile station UE is configured to transmit uplink data to the radio base station at a predetermined cycle using uplink radio r...

Abstract

Provided is a mobile communication method in which a mobile station UE uses an uplink radio resource allocated by predetermined scheduling information at a predetermined cycle so as to transmit uplink data transmitted from a radio base station eNB. The method includes: step A for reporting information on the predetermined cycle and the uplink radio resource to the mobile station UE; step B for reporting predetermined scheduling information to the mobile station UE; and step C for transmitting uplink data at a predetermined cycle starting at the moment decided by the received predetermined scheduling information by using the uplink radio resource allocated by the predetermined scheduling information. If step C finds that the information on the uplink radio resource contradicts with the information reported by the predetermined scheduling information, the predetermined scheduling information is discarded.

Description

technical field [0001] The present invention relates to a mobile communication method, a mobile station, and a radio base station for transmitting uplink data to a radio base station by a mobile station using uplink radio resources fixedly allocated at predetermined intervals starting from an allocation start time. Background technique [0002] 3GPP, the standardization organization of W-CDMA, studies the communication to be the successor to W-CDMA (Wideband-Code Division Multiple Access) or HSDPA (High Speed ​​Downlink Packet Access) mode, that is, the LTE (Long Term Evolution) mode, and its specification work is in progress. [0003] In the LTE scheme, studies are underway to use OFDMA for the downlink and SC-FDMA (Single-Carrier Frequency Division Multiple Access) for the uplink as the radio access scheme. [0004] OFDMA is a method of dividing the frequency band into multiple narrow frequency bands (subcarriers), and loading data on each frequency band for transmission....
