We claim:
1. A mobile communication system comprising a base station (1301), a
neighboring base station (1303) other than the base station (1301), and a mobile
terminal (1305) which can perform radio communication with the neighboring base
station (1303),
wherein the base station (1301) is configured to transmit a configuration information to the mobile terminal (1305) by means of a dedicated signal, the configuration information being used by the mobile terminal (1305) for uplink transmission from the mobile terminal (1305) to the neighboring base station (1303) and including Random Access Channel configuration related information and an information related to transmission power of a Physical Random Access Channel,
the mobile terminal (1305) is configured to receive the configuration information from the base station (1301) by means of the dedicated signal, and
the mobile terminal (1305) is configured to determine a transmission power of a Physical Random Access Channel being transmitted to the neighboring base station (1303) by using the configuration information.
2. The mobile communication system according to claim 1,
wherein the configuration information includes a preamble format for the uplink transmission.
3. The mobile communication system according to claim 1,
wherein the configuration information includes an uplink carrier frequency and an uplink frequency band.
4. A base station (1301) used in a mobile communication system comprising the
base station (1301), a neighboring base station (1303) other than the base station
(1301), and a mobile terminal (1305) which can perform radio communication with
the neighboring base station (1303),
115

wherein the base station (1301) is configured to transmit a configuration information to the mobile terminal (1305) by means of a dedicated signal, the configuration information being used by the mobile terminal (1305) for uplink transmission from the mobile terminal (1305) to the neighboring base station (1303) and including Random Access Channel configuration related information and an information related to transmission power of a Physical Random Access Channel.
5. A mobile terminal (1305) used in a mobile communication system comprising
a base station(1301) , a neighboring base station (1303) other than the base station (1301), and the mobile terminal (1305) being able to perform radio communication with the neighboring base station (1303),
wherein the mobile terminal (1305) is configured to receive a configuration information from the base station (1301) by means of a dedicated signal, the configuration information being used by the mobile terminal (1305) for uplink transmission from the mobile terminal (1305) to the neighboring base station (1303) and including Random Access Channel configuration related information and an information related to transmission power of a Physical Random Access Channel, and
wherein the mobile terminal (1305) is configured to determine a transmission power of a Physical Random Access Channel being transmitted to the neighboring base station (1303) by using the configuration information.
