Definitions
- the measurement result in subcarrier units is compared with a predetermined threshold, and the comparison result is format-converted to generate a plurality of reception quality data in bit notation. Since the data with the smallest data amount is selected from the reception quality data and is transmitted to the base station apparatus on the uplink, the transmission of the reception quality data is expended and the channel resources of the uplink are released. Thus, it is possible to improve the throughput of the uplink.
- a comparison result between the reception quality of each subcarrier of the multicarrier signal and a predetermined threshold is represented by a bit in the order of subcarrier number.
- the plurality of reception quality data generated in the generation step may include the comparison result in the order of subcarrier numbers of subcarriers constituting the multicarrier signal. First reception quality data expressed in bits, Based on the comparison result, the second reception quality data in which the subcarrier number of the subcarrier whose reception quality is equal to or more than the threshold value is expressed in bits, and based on the comparison result, the reception quality is less than the threshold value. And third reception quality data in which the subcarrier number of the subcarrier is expressed in bits, wherein in the control information creating step, the base station apparatus transmits the uplink multicarrier signal in the determination step.
- a plurality of reception quality data in bit notation is generated by format conversion of a comparison result between a reception result of a downlink multicarrier signal in subcarrier units and a predetermined threshold value.
- the plurality of generated reception quality data is selected and transmitted to the base station apparatus using an uplink multicarrier signal, and is used for transmitting the reception quality data of the downlink multicarrier signal.
- Upstream channel resources can be released to improve uplink throughput.
- the format of each of the first to third reception quality data will be described.
- the first reception quality data for each subcarrier of the downlink multicarrier signal, if the measured value of the received SIR is equal to or greater than the threshold T, it is set to ⁇ 1 '', and if the measured value of the received SIR is less than the threshold T, Is expressed in bits as “0”.
- a 2-bit identification number for example, "00" is added to at least one of the first and the last reception quality data to cause the format determination unit 216 to identify that the data is the first reception quality data. Is done. Therefore, in the case of the format of the first reception quality data shown in FIG.
- the formats of first to third reception quality data of the downlink multicarrier signal generated by reception quality data generation and selection section 110 are all simple. Therefore, it is possible to generate a plurality of pieces of reception quality data having different data amounts for a downlink multicarrier signal without increasing the signal processing load of the reception quality data generation selection unit 110 in real time.
- the threshold value T is set to increase or decrease in synchronization with the change in the number of wireless communication terminal devices 500 that perform simultaneous communication with base station device 200
- the reception quality data generation / selection section 510 makes it easier to select the second reception quality data of the downlink multi-carrier signal.
- the quality data generation / selection section 510 makes it easier to select the third reception quality data of the downlink multicarrier signal.
- the threshold value is set to increase or decrease in synchronization with the change in the number of wireless communication terminal devices 500 that perform simultaneous communication with the base station device 200, the number of wireless communication terminal devices 500 increases.
- Each functional block used in the description of each of the above embodiments is typically an integrated circuit. It is realized as an LSI. These may be individually made into one chip, or may be made into one chip so as to include a part or all of them.
- a reception quality reporting method, a radio communication terminal apparatus, and a base station apparatus release uplink channel resources used for transmission of reception quality data of a downlink multicarrier signal, and release uplink channel resources. It has the effect of improving throughput, and is useful for wireless communication systems using the OFDM scheme.
