Abstract: A radio tenninal, radio base station, channel signal forming method and channel signal receiving method wherein when an upstream unit band and a plurality of downstream unit bands associated therewith are used to perform communications, the quality of downstream assignment control information can be prevented from being degraded. In a base station (100), the PDCCH signals including upstream assignment control information are limited to ones that are placed in some of the downstream unit bands. This can reduce the probability of performance of zero padding to downstream assignment control information having greater importance. Also in the base station (100), the PDCCH signals of the downstream unit bands other than the basic unit band include only downstream resource assignment information. For this reason, in the individual regions of the downstream unit bands other than the basic unit band, the bandwidth of the downstream unit bands is always used as a reference of size adjustment and hence requires no information size adjustment. As a result, there is no need of performing zero padding to the downstream assignment control information, so that the quality of downstream assignment control information can be prevented from being degraded.

Abstract: A terminal apparatus (1), which is a radio transmitting/receiving apparatus, receives a pilot channel signal for use in measuring reception quality and a sync channel signal for use in establishing synchronization from a small-cell base station (home eNB). The terminal apparatus (1), which has stored a white list indicating accessible small cells, determines, based on the white list and the PCIs of CSG cells acquired from a sync channel, whether the CSG cell of a handover destination can be accessed. The terminal apparatus (1) then adds the PCIs and CGIs to a reception quality measurement report and transmits the measurement report to a macro eNB (base station apparatus (2)). In this way, even when a plurality of CSG cells using the same PCI exist in a macro cell, needless signalings can be suppressed, while unnecessary resources can be prevented from being allocated.

Abstract: A communication terminal is capable of simultaneously communicating through a plurality of carriers by carrier aggregation, and the communication terminal comprises: a quality measurement unit for measuring the reception quality of a radio wave transmitted through a plurality of carriers from a base station of a connected cell to obtain a measured value; a primary carrier storage unit storing information specifying a primary carrier chosen from the plurality of carriers; a comparator for comparing a measured value of the primary carrier measured by the quality measurement unit to a threshold value; and a cell search unit for searching for another cell when the measured value of the primary carrier is less than or equal to the threshold value. Consequently, a search threshold value for carrier aggregation can be appropriately determined to perform a cell search and a quality measurement.
