Abstract

A radio receiving apparatus and a reference signal on an unused unit band measurement method wherein QoS can be maintained and measured in a wireless communication system that simultaneously uses first and second frequency bands, each of which includes a plurality of unit bands, to transmit a series of data signal sequences. In a terminal (100), a measurement executing part (150-1) measures, during a first measurement interval overlapping with the second data reception interval and time-divided together with the first data reception interval, the reception power of a reference signal on an unused unit band transmitted over a unit band other than a first used unit band in the first frequency band. In this way, the terminal (100) can execute a data communication with a source base station (200) over any one of the frequency bands at any timing, which can reduce the delay of a downstream signal transmission. That is, a terminal (100) can be realized which can maintain and measure QoS.

Claims

1-4. -4. (canceled)

5. A radio receiving apparatus comprising:

a data receiving section that receives a data signal transmitted using a first used unit band included in a first frequency band comprising a plurality of unit bands, in a first data reception interval, and receives a data signal transmitted using a second used unit band included in a second frequency band including a plurality of unit bands, in a second data reception interval; and

a reception power measuring section that measures a reception power of a reference signal on an unused unit band transmitted in a unit band different from the first used unit band and the second used unit band, in a first measurement interval,

wherein the first measurement interval is time division multiplexed with the second data reception interval and set independently from the first data reception interval.

6. The radio receiving apparatus according to claim 5, wherein the first measurement interval is time division multiplexed with the second data reception interval and set to overlap the first data reception interval.

7. The radio receiving apparatus according to claim 6, wherein the reception power measuring section is a second frequency band measuring section that measures the reception power of the second frequency band, and further comprises a first frequency band measuring section that measures a reception power of the reference signal on the unused unit band in the first frequency band in a communication priority mode to perform the measurement in the first data reception interval and a second measurement interval which is time division multiplexed with the first measurement interval.

8. The radio receiving apparatus according to claim 7, further comprising a measurement control section that switches between the communication priority mode and a measurement priority mode in which the first measurement interval and the second measurement interval are a same interval.

9. A radio receiving method comprising:

receiving a data signal transmitted using a first used unit band included in a first frequency band comprising a plurality of unit bands, in a first data reception interval, and receiving a data signal transmitted using a second used unit band included in a second frequency band including a plurality of unit bands, in a second data reception interval; and

measuring a reception power of a reference signal on an unused unit band transmitted in a unit band different from the first used unit band and the second used unit band, in a first measurement interval,

wherein the measurement interval overlaps the first data reception interval and is time division multiplexed with the second data reception interval.
