Embodiment 1

[0076] refer to image 3 A mobile communication system including a mobile station and a base station apparatus according to an embodiment of the present invention will be described.

[0077] The mobile communication system 1000 is, for example, a system to which Evolved UTRA and UTRAN (Evolved UTRA and UTRAN) (also called: Long Term Evolution (Long Term Evolution), or Super (Super) 3G) is applied. The mobile communication system 100 includes: a base station apparatus (eNB: eNode B) 200; and a plurality of mobile stations 100n (1001, 1002, 1003, . The base station device 200 is connected to an upper layer station, for example, an access gateway device 300 , and the access gateway device 300 is connected to a core network 400 . Among them, the mobile station 100 n communicates with the base station apparatus 200 in the cell 50 through Evolved UTRA and UTRAN.

[0078] Since each mobile station (1001, 1002, 1003, . . . 100n) has the same configuration, function, and state, it wi...

Embodiment 2

[0234] In this embodiment, the structure of the above-mentioned mobile communication system 1000, the structure of the mobile station 100n, and the structure of the base station apparatus 200 are substantially the same as those of the above-mentioned embodiments, and therefore descriptions of overlapping parts are omitted.

[0235] The difference mainly lies in the access gateway device 300, the layer 1 processing unit 1081 and the maximum transmission power control unit 1083 in the mobile station 100n.

[0236] The access gateway device 300 transmits a NAS message to the mobile station 100n performing location registration. The above NAS message is transmitted to the mobile station 100n via the base station apparatus 200 . The above NAS message includes operator information, country code, Public Land Mobile Network identity (PLMN: Public Land Mobile Network identity) and the like.

[0237] The base station apparatus 200 receives the above-mentioned NAS message from the acces...

Abstract

A user apparatus which wirelessly communicates with a base station apparatus within a mobile communications system is disclosed. The user apparatus includes a receive unit which receives control information in downlink; and a transmit unit which transmits a first channel in uplink, wherein the transmit unit, based on the control information, makes a value of a maximum transmit power of the first channel smaller than that of a nominal power specified for the mobile communications system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a mobile communication system, base station device, user device and method using the next generation mobile communication technology. Background technique [0002] 3GPP, the standardization organization of W-CDMA, is discussing a communication method that will be the successor to Wideband Code Division Multiple Access (W-CDMA), High Speed ​​Downlink Packet Access (HSDPA), and High Speed ​​Uplink Packet Access (HSUPA), that is, Long Term Evolution. As the wireless access method in LTE, Orthogonal Frequency Division Multiple Access (OFDM: Orthogonal Frequency Division Multiplexing: Orthogonal Frequency Division Multiplexing) method is favored for the downlink, and single-carrier frequency division multiple access is favored for the uplink. (SC-FDMA: Single-Carrier Frequency Division Multiple Access: Single-Carrier Frequency Division Multiple Access) scheme (fo...
