Description

Mobile communication system, base station apparatus, mobile station apparatus, and communication method

The present invention relates to a mobile communication system and a communication method including a base station device and a mobile station device.

3GPP (3rd Generation Partnership Project) examines and creates specifications for mobile communication systems based on networks developed from W-CDMA (Wideband-Code Division Multiple Access) and GSM (Global System for Mobile Communications). It is a project. In 3GPP, the W-CDMA system is standardized as a third generation cellular mobile communication system, and services are started sequentially. In addition, HSDPA (High-speed Downlink Packet Access), which further increases the communication speed, has been standardized and a service has been started. In 3GPP, the evolution of the third generation radio access technology (hereinafter referred to as “LTE (Long Terminology Evolution)” or “EUTRA (Evolved Universal University Terrestrial Radio Access)) and a wider frequency band are used. Further, studies on a mobile communication system (hereinafter referred to as “LTE-A Evolution-Advanced” or “Advanced-EUTRA”) that realizes higher-speed data transmission / reception are in progress.

As communication methods in LTE, OFDMA (Orthogonal Frequency Division Multiple Access) that performs user multiplexing using subcarriers orthogonal to each other and SC-FDMA (Single Carrier-Frequency Division Multiple Access) are being studied. . That is, an OFDMA scheme that is a multicarrier communication scheme is proposed for the downlink, and an SC-FDMA scheme that is a single carrier communication scheme is proposed for the uplink.

On the other hand, as a communication method in LTE-A, the OFDMA method is used in the downlink, and in the uplink, in addition to the SC-FDMA method, Clustered-SC-FDMA (Clustered-Single-Carrier-Frequency-Division-Multiple-Access, DFT-s -OFDM with Spectrum Division Control (also called DFT-precoded OFDM) is being considered. Here, in LTE and LTE-A, the SC-FDMA system and the Clustered-SC-FDMA system proposed as uplink communication systems are based on the characteristics of the single carrier communication system (depending on the single carrier characteristics), and data (information ) Is transmitted at a low PAPR (Peak to Average Power Ratio: peak power to average power ratio, transmission power).

In LTE-A, a frequency band used in a general mobile communication system is continuous, whereas a plurality of continuous and / or discontinuous frequency bands (hereinafter referred to as “component carrier, element carrier (CC) Carrier) ”or“ carrier component, carrier element (CC: Carrier Component) ”is used in combination to operate as a single frequency band (wideband frequency band) (frequency band aggregation: Carrier aggregation) , Spectrum aggregation, Frequency aggregation, etc.). Furthermore, in order for the base station apparatus and the mobile station apparatus to communicate using a wide frequency band more flexibly, the frequency band used for downlink communication and the frequency band used for uplink communication are different. It has also been proposed to use a frequency bandwidth (Asymmetric carrier aggregation) (Non-Patent Document 1).

FIG. 7 is a diagram for explaining a mobile communication system in which frequency bands are aggregated in the prior art. It is symmetric that the frequency band used for downlink (DL: Down ような Link) communication and the frequency band used for uplink (UL: Up Link) communication as shown in FIG. It is also called frequency band aggregation (Symmetric carrier aggregation). As shown in FIG. 7, the base station apparatus and the mobile station apparatus can use a wide band composed of a plurality of component carriers by using a plurality of component carriers that are continuous and / or discontinuous frequency bands. Communication can be performed in the frequency band. In FIG. 7, as an example, five frequency bands (hereinafter also referred to as DL system band and DL system bandwidth) used for downlink communication having a bandwidth of 100 MHz have five bandwidths of 20 MHz. It is shown that it is configured by downlink component carriers (DCC1: Downlink Component Carrier1, DCC2, DCC3, DCC4, DCC5). Further, as an example, the frequency band used for uplink communication with a bandwidth of 100 MHz (hereinafter also referred to as UL system band or UL system bandwidth) has five uplinks with a bandwidth of 20 MHz. It shows that it is configured by component carriers (UCC1: Uplink Component Carrier1, UCC2, UCC3, UCC4, UCC5).

In FIG. 7, each downlink component carrier has a downlink channel such as a physical downlink control channel (hereinafter referred to as PDCCH: Physical Downlink Control Channel) or a physical downlink shared channel (hereinafter referred to as PDSCH: Physical Downlink Shared Channel). Be placed. The base station apparatus transmits control information (resource allocation information, MCS (Modulation coding scheme: Coding scheme) information, HARQ (hybrid automatic retransmission request) for transmitting a downlink transport block transmitted using PDSCH. : Hybrid (Automatic (Repeat Request) processing information) is allocated to the mobile station apparatus using the PDCCH, and the downlink transport block is transmitted to the mobile station apparatus using the PDSCH. That is, in FIG. 7, the base station apparatus can transmit up to five downlink transport blocks (or PDSCH) to the mobile station apparatus in the same subframe.

Each uplink component carrier has an uplink channel such as a physical uplink control channel (hereinafter PUCCH: Physical Uplink Control Channel) or a physical uplink shared channel (hereinafter PUSCH: Physical Uplink Shared Channel). The The mobile station apparatus uses PUCCH and / or PUSCH to perform channel state information (CSI: Channel Statement information or Channel statistical information) and ACK / NACK (Acknowledgement: Positive Acknowledgement / Negative) in HARQ for the downlink transport block. Response: Information indicating Negative 示す Acknowledgement, ACK or NACK) and uplink control information (UCI: Uplink スケジューリング Control Information) such as a scheduling request (SR) is transmitted to the base station apparatus. In FIG. 7, the mobile station apparatus can transmit up to five uplink transport blocks (or PUSCH) to the base station apparatus in the same subframe.

Here, the channel state information indicates information indicating the channel quality for the downlink signal transmitted from the mobile station apparatus to the base station apparatus. The mobile station apparatus measures (calculates and generates) the channel quality for the downlink signal transmitted from the base station apparatus, and transmits (reports and feeds back) the channel quality information to the base station apparatus. Information indicating the channel state for the downlink signal transmitted from the mobile station apparatus to the base station apparatus includes channel state information (CSI), a channel quality identifier (CQI), a precoding matrix identifier (PMI: Precoding Matrix Indicator) and rank identifier (RI: Rank Indicator) are included.

Here, PMI and RI are based on SDM (Space Division Multiplexing), SFBC (Space-Frequency Block Diversity), CDD (Cycle), where the base station apparatus and the mobile station apparatus use MIMO (Multiple Input Multiple Multiple Output). This is used for communication using a transmission diversity method such as Delay Diversity). MIMO is a general term for a multi-input / multi-output system or technology. The base station apparatus and mobile station apparatus use multiple antennas on the transmitting side and the receiving side, and make the number of input / output branches multiple. To transmit. Here, a unit of a signal sequence that can be transmitted by spatial multiplexing using MIMO is called a stream, and the number of streams (Rank: rank) is determined by the base station apparatus in consideration of a channel state. At this time, the number of streams (Rank) required by the mobile station apparatus is transmitted as RI from the mobile station apparatus to the base station apparatus.

In addition, when using SDM in the downlink, in order to correctly separate the information of a plurality of streams transmitted from each antenna, preprocessing is performed on the transmission signal sequence in advance (this is referred to as “precoding”). "). Information regarding this precoding can be measured (calculated and generated) based on the channel state estimated by the mobile station apparatus, and is transmitted as PMI from the mobile station apparatus to the base station apparatus.

Similarly, FIG. 8 is a diagram for explaining a mobile communication system in which asymmetric frequency bands are aggregated in the prior art. As shown in FIG. 8, the base station apparatus and the mobile station apparatus have different frequency bands used for downlink communication and frequency bands used for uplink communication, and configure these frequency bands. Therefore, it is possible to perform communication in a wide frequency band by using component carriers that are continuous and / or discontinuous frequency bands in combination. In FIG. 8, as an example, five downlink component carriers (DCC1, DCC2, DCC3, DCC4, DCC5) having a frequency band of 20 MHz are used for downlink communication having a bandwidth of 100 MHz. And the frequency band used for uplink communication having a bandwidth of 40 MHz is configured by two uplink component carriers (UCC1, UCC2) having a bandwidth of 20 MHz. Show.

Here, in FIG. 8, downlink / uplink channels are allocated to the downlink / uplink component carriers, respectively, and the base station apparatus allocates PDSCH to the mobile station apparatus using PDCCH and uses PDSCH. Then, the downlink transport block is transmitted to the mobile station apparatus. That is, in FIG. 8, the base station apparatus can transmit up to five downlink transport blocks (or PDSCH) to the mobile station apparatus in the same subframe.

Also, the mobile station apparatus uses PUCCH and / or PUSCH to transmit channel state information, information indicating ACK / NACK in HARQ for the downlink transport block, and uplink control information such as a scheduling request to the base station apparatus. Send to. In FIG. 8, the mobile station apparatus can transmit up to five uplink transport blocks (or PUSCH) to the base station apparatus in the same subframe.

FIG. 9 is a diagram illustrating an example of transmission of channel state information from the mobile station apparatus to the base station apparatus in the conventional technique. The base station apparatus (901) instructs the mobile station apparatus (902) to use which radio resource (radio resource block) to transmit the uplink signal (904) including the channel state information. (903) is transmitted. The mobile station apparatus transmits channel state information to the base station apparatus using the radio resource instructed by the base station apparatus. In FIG. 9, for example, the mobile station apparatus arranges an uplink signal including periodic channel state information (P-CSI: Periodic） CSI) in the PUCCH resource allocated by the base station apparatus, and sends the uplink signal to the base station apparatus. Send. Also, for example, the mobile station apparatus arranges an uplink signal including aperiodic channel state information (A-CSI: Aperiodic CSI) in the PUSCH resource allocated by the base station apparatus, and transmits the uplink signal to the base station apparatus. (Non-Patent Document 2).

However, in the conventional technique, when the base station apparatus and the mobile station apparatus perform communication using a plurality of component carriers in combination, the mobile station apparatus transmits periodic channel state information to the base station apparatus. The transmission method for transmitting periodic channel state information has not been clarified. The base station apparatus can perform efficient downlink scheduling based on channel state information transmitted from the mobile station apparatus (can efficiently allocate radio resources to the mobile station apparatus). .
