This application is a U.S. National Phase under 35 U.S.C. §371 of International Application No. PCT/JP2011/055377, filed Mar. 8, 2011.
The present invention relates to a mobile communication system made up of a base station apparatus and a mobile station apparatus, and a mobile communication method.
An international standardization project, 3GPP (3rd Generation Partnership Project) is discussing specifications of a network developed from W-CDMA (Wideband-Code Division Multiple Access) and GSM (Global System for Mobile Communications) as a system of next-generation cellular mobile communication.
FIG. 1 is a conceptual diagram of a configuration of physical channels according to an embodiment of the present invention.
FIG. 2 is a block diagram of a general configuration of a base station apparatus according to the embodiment of the present invention.
FIG. 3 is a block diagram of a general configuration of a mobile station apparatus according to the embodiment of the present invention.
Embodiments according to the present invention will now be described with reference to the drawings. FIG. 1 is a diagram of one exemplary configuration of channels of an embodiment of the present invention. Downlink physical channels are made up of a physical broadcast channel (PBCH), a PDCCH, a PDSCH, and a physical hybrid ARQ indicator channel (PHICH). Uplink physical channels are made up of a PUSCH and a PUCCH.
The PBCH maps a broadcast channel (BCH) at intervals of 40 milliseconds. Blind detection is performed for the timing of 40 milliseconds. Therefore, explicit signaling is not performed for the presentation of the timing. A sub-frame including the PBCH can be decoded by itself (self-decodable).
The PDCCH is a channel used for transmitting downlink control information. The PDCCH is a channel used for notifying a mobile station apparatus of resource allocation of the PDSCH, and uplink transmission permission that is resource allocation of the PUSCH. The PDCCH is made up of a plurality of CCEs, and a mobile station apparatus detects the PDCCH made up of the CCEs to receive the PDCCH from a base station apparatus. A CCE is made up of a plurality of resource element groups (REGs, also referred to as mini-CCEs) distributed in frequency and time domains. A resource element is a unit resource made up of one OFDM symbol (time component) and one sub-carrier (frequency component) and, for example, an REG is made up of four downlink resource elements consecutive in the frequency domain, except a downlink pilot channel, in the frequency domain in the same OFDM symbol. For example, one PDCCH is made up of one, two, four, and eight CCEs having the consecutive numbers identifying the CCEs (CCE index).
