Abstract: A base station (1) is connectable to a mobile station (4) by a plurality of Radio Access Technologies (RATs) including first and second RATs. The base station (1) is configured to be able to use a communication path (400) that passes through a first upstream network (140) corresponding to the first RAT, when the mobile station (4) performs communication via the second RAT. This enables, for example, efficient use of the upstream networks when the Multi-RAT base station (1) supports a plurality of upstream networks.

Abstract: In one embodiment, a radio terminal (2) is used in a radio communication system (100) and communicates with a radio station (1). The radio terminal (2) includes a measurement unit (20). The measurement unit (20) operates to perform, using a terminal measurement procedure for executing a first terminal measurement corresponding to radio access technology applied to the radio communication system (100), a second terminal measurement of a shared frequency shared by a plurality of radio systems including the radio communication system (100). This embodiment therefore contributes to simplification of a measurement function which should be supported by the radio terminal when the radio communication system uses a shared frequency (e.g., TVWS) shared by the plurality of radio systems.

Abstract: To solve a problem that unless all of a plurality of AICH signature states are correctly decoded, the contents of reception results cannot be recognized and the error rate of signature decoding will be high. In this embodiment, a base station uses, out of a signature combination, the signature of at least one predetermined position to indicate information containing a preamble reception result and uses the signature of a position other than the predetermined position to indicate a transmission profile information number of an uplink channel for notification to a user equipment. Thus, the error rate related to reception results can be reduced as compared with the case where a single signature combination is used to notify all pieces of information.

Abstract: A radio terminal (1) updates a preconfigured radio parameter (409, 814) stored in a memory (406, 810) coupled to the radio terminal (1). The preconfigured radio parameter (409, 814) is used by the radio terminal (1) to perform at least one of discovery and direct communication without the assistance of a Public Land Mobile Network (100). This contributes, for example, to flexible adaptation to conditions under which the ProSe communication without the assistance of a network is performed.
