- Subcarrier mapping is implemented by the “Release 5” standard HSDPA (High Speed Downlink Packet Access).
- HSDPA High Speed Downlink Packet Access
- modulation and coding methods suitable for high-speed communication are assigned to high-quality lines, and highly stable modulation and coding methods are assigned to low-quality lines. In this way, communication quality is reduced as a whole communication system by recognizing the line quality and changing the modulation and coding methods.
- Patent Document 1 discloses a technique for improving communication efficiency by selecting a transmission schedule according to the type of information to be transmitted.

- Patent Document 2 can reduce the influence of subcarrier frequency change (frequency fading) using a frequency hopping pattern, the frequency and position other than the predetermined frequency fluctuation (hopping pattern), It cannot cope with changes in the line environment due to fading such as time. That is, there is a probability that the control signal of high importance will be lost due to changes in the communication environment of the subcarrier due to frequency fluctuation, position change (movement) and time change.
- An object of the present invention is to provide a base station, a mobile station, and a subcarrier mapping method that solves the above-mentioned problems, uses the channel quality information, responds to changes in the communication environment of the subcarrier, and efficiently uses the subcarrier. It is to provide.
- the base station determines the state of the communication environment between the mobile station (base station) and the mobile station based on the channel quality information notified from the mobile station.
- the transmission information relating to communication control is selectively mapped to specific subcarriers used for transport based on the identified communication environment state.

- FIG. 2 is a sequence diagram of a communication system for allocating subcarriers according to the embodiment.
- Fig. 3 is an illustration showing C Q I reported from the mobile station for each resource block.
- FIG. 4 is a block diagram showing a part of a mobile station according to another embodiment.
- FIG. 5 is a sequence diagram of a communication system for allocating subcarriers according to another embodiment. Best Mode for Carrying Out the Invention:
- FIG. 1 is a block diagram showing a part of mobile station 100 according to an embodiment.
- FIG. 1 is a part of a general block diagram showing a mobile station and shows the features of the present invention.
- the FFT (Fast Fourier Transform) unit 101 receives the I ch and Q ch signals subjected to quadrature detection, and transmits the subcarrier signal to the ⁇ 3? 31: 0 8] demodulator 102 and CQ I measurement unit 103. .
- QP SKZQAM demodulation section 102 receives the subcarrier signal, demodulates it into symbols, and transmits the demodulated symbols to subcarrier demapping section 106 and control channel decoding section 104.
- the CQ I measurement unit 103 receives the subcarrier signal, measures the CQ I, and transmits the measured CQ I to the base station. At the same time, the CQ I measurement unit 103 transmits the CQ I to the RB (Resource Block) rank determination unit 105.
- RB Resource Block
- Control channel decoding section 104 decodes the subcarrier signal received from ⁇ 3? 31: (3 8) ⁇ demodulating section 102 into DL-SCH allocated resource block information, and the control channel of control channel decoding section 104 Since the decryption process is the same as the prior art, the description is omitted.
- the RB rank determination unit 105 includes the allocation resource block information based on the allocation resource block information notified from the control channel decoding unit 104, the average CQ I notified from the CQ I measurement unit 103, and the CQ I of each resource block group.
- Average CQ I threshold is higher than threshold value N by more than CQ I resource block, and the identification result is transmitted to subcarrier demapping section 106.
- the identification process is a process for identifying whether systematic bits are preferentially mapped to a specific resource block.
- the systematic bits are control information (signals) for down-link lines and include, for example, information such as convolutional coding and turbo coding, modulation schemes, error correction, and the like.
- the subcarrier demap unit 106 receives the identification result of the RB rank determination unit 105. Then, using the identification result, it is determined whether or not the systematic bits are preferentially mapped to a specific resource block, and if they are mapped, subcarrier demapping is performed in the order of the Dinterleave input. The signal is sent to the Dinta Reeve 107.
- the processing after the deinterleaving unit 107 and the H-ARQ unit 108 is the same as that of the prior art, so the description is omitted.
- the base station 200 can be configured in the same manner as in the prior art. In other words, any configuration is possible as long as CQ I can be identified and transmission information can be arbitrarily mapped to a subcarrier.
- the mobile station 100 starts communication or after communication from the base station 200 is started, when establishing a downlink between the mobile station and the base station, the mobile station is connected between the base stations. It is characterized by the subcarrier mapping method using the CQ I value and the transmission information that is mapped to the subcarrier and carried.
- FIG. 2 is a sequence diagram of a communication system that maps the subcarriers according to the embodiment.
- the mobile station 100 and the base station 200 start DL-SCH communication (step S 101).
- the mobile station 100 measures the CQ I for each resource block using the CQ I measuring unit 103 and notifies the CQ I to the base station 2 ° 0 (step S 102).
- Base station 200 allocates resource blocks based on the CQ I notification from mobile station 100 (step S 103).
- the base station 200 identifies whether the CQ I of the specific resource block allocated to the mobile station 100 is greater than the average CQ I by a threshold N or more. That is, the communication environment is identified. (Step S104). Details of the method for identifying the communication environment will be described later with reference to FIG.
- Base station 200 determines that the CQ I of all identified resource blocks is the average CQ I + threshold If the value is smaller than the value N, subcarrier mapping is performed in the order of low frequency, high frequency, or high frequency in the order of interleave output, and DL-SCH is transmitted (step S 105). This is because the base station 200 determines that there is little difference in the propagation environment of each resource block and prioritizes the frequency diversity effect.
- the base station 200 When the average CQ I + threshold N or more, the base station 200 performs subcarrier mapping for preferentially assigning systematic bits to the resource block of the CQ I, and transmits DL-SCH. That is, important information is mapped to a resource block with a good communication environment (step S106). Parity bits etc. are mapped in the remaining (other) resource blocks.
- the mobile station 100 receives the DL—S CH transmitted from the base station 200, analyzes the control information (control signal) included in the DL—SCH, and identifies the resource block including the DL—SCH addressed to itself. .
- Mobile station 100 acquires CQ I for the resource block identified using CQ I measuring section 103, and RB rank determining section 105 identifies CQ I that is equal to or greater than threshold C from average CQ I in resource block. (Step S107).
- the mobile station 100 When the identified result includes a resource block having an average CQ 1 + threshold value N or more, the mobile station 100 identifies that the systematic bit is preferentially mapped to the resource block. If there is no resource block with average CQ I + threshold N or more, it is identified that the frequency is mapped in the order of low frequency, high order, or high order in the interleaved output order. Based on the identification result, the mobile station 100 performs subcarrier demapping on the demodulated signal, and configures an input signal for the Dinterleaver 107 (step S 108).
- the base station can notify the result (method) of the subcarrier mapping without transmitting a new additional control signal using the CQ I reported by the mobile station. .
- the effect similar to the effect of notifying the subcarrier mapping control information can be obtained and the communication can be stabilized.
- the difference between the average CQ I and the notified CQ I is used as a threshold for control and execution. Therefore, it is possible to realize good communication characteristics by adaptively selecting whether to give priority to resource blocks in a good reception environment or to give priority to frequency diversity effects.
- good communication characteristics can be realized by mapping systematic bits to resource blocks with good communication environment.
- CQ I can be used to respond to changes in the subcarrier communication environment based on changes in position and time.
- FIG. 3 is an exemplary diagram showing the CQ I received from the mobile station 100 and received by the base station 200 for each resource block.
- the communication bandwidth is divided into resource blocks (groups), which are units for measuring CQI. In the example of Fig. 3, it is divided into resource blocks of 6 bands from 301 to 306.
- a threshold is used as a criterion for identifying the allocated resource block.
- the identification result is YES, systematic bits are preferentially mapped to the resource block. That is, in the example of FIG. 3, systematic bits are preferentially mapped to the resource block 303 shown by diagonal lines. If the identification result is No, the systematic bits are mapped in the interleave output order.
- Another identification method does not use average CQ I, but identifies whether CQ I is greater than or less than a threshold. Similarly, identify the average CQ I, the higher CQ I above the average CQ I, and their resource blocks.
- threshold value may be defined by other methods and is not particularly limited.
- the CQI notification method has been described according to the Best-M method. However, another notification method such as a DCT (Discrete Cosign Transform) method may be used.
- the mobile station 100 uniquely identifies the resource block to which the systematic bits are mapped.
- the base station may notify the resource block information as an identification signal. Absent.
- FIGS. 4 and 5 are obtained.
- FIG. 4 is a block diagram showing a part of mobile station 400 according to another embodiment.
- the RB rank determination unit 1 06 is deleted from the mobile station 1 0 0 described above.
- the control channel decoding unit 40 4 of the mobile station 400 decodes the subcarrier signal received from the QPSK / Q AM demodulation unit 40 2 into D L—S C H allocated resource block information.
- the subcarrier demap unit 4 06 identifies whether or not systematic bits are preferentially mapped to a specific resource block using the resource block information transmitted from the control channel decoding unit 4 0 4. If this is the case, subcarrier de-mabbing is performed in the order of the Dinter Leave input, and a signal is transmitted to the Dinter Leave section 1 07.
- FIG. 5 is a sequence diagram of a communication system for mapping subcarriers according to another embodiment.
- step S 2 0 1 to step S 2 0 3 are the same as those in the sequence diagram of FIG.
- step S 2 0 4 the base station 2 0 0 identifies the resource block, and further generates an identification signal.
- the resource block may be identified by the same identification method as in the embodiment.
- step S 2 0 5 and step S 2 0 6 subcarrier demapping is performed, identification information is added, and D S—S C H is transmitted to mobile station 4 0 0.
- step 20 07 the mobile station 400 uses the identification signal to decode the received signal. Other operations are the same as those of the mobile station 100.
- 1 and 4 may be realized by hardware (logic), or may be realized by using a CPU and software.
- the present invention can be applied to all communication systems having mobile stations. It is also useful for communication equipment that uses OFDM (Orthogonal Frequency Division Multiplexing) and OFC DM (Orthogonal Frequency and Code Division Multiplexing).
