    Abstract: A radio communication device capable of randomizing both inter-cell interference and intra-cell interference. In this device, a spreading section primarily spreads a response signal in a ZAC sequence set by a control unit . A spreading section secondarily spreads the primarily spread response signal in a block-wise spreading code sequence set by the control unit . The control unit controls the cyclic shift amount of the ZAC sequence used for the primary spreading in the spreading section and the block-wise spreading code sequence used for the secondary spreading in the spreading section according to a set hopping pattern. The hopping pattern set by the control unit is made up of two hierarchies. An LB-based hopping pattern different for each cell is defined in the first hierarchy in order to randomize the inter-cell interference. A hopping pattern different for each mobile station is defined in the second hierarchy in order to randomize the intra-cell interference.

    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: Provided are a radio transmission device and a radio transmission method capable of improving downlink and uplink throughput even when performing dynamic symbol allocation. In the device and the method, BS and MS share a table correlating a basic TF as a combination of parameters such as TB size used for transmitting only user data, an allocation RB quantity, a modulation method, and an encoding ratio, with a derived TF having user data of different TB size by combining L1/L2 control information. Even when multiplexing L1/L2 control information, Index corresponding to the basic TF is reported from BS to MS.

    Abstract: Method of scrambling signals, transmission point device and user equipment using the method are provided. The method is for scrambling signals assigned on predetermined radio resources of at least one layer of resource blocks with the same time and frequency resources, and comprises the steps of: sending an ID table to a user equipment through higher layer signaling, the ID table being a subset of the whole ID space and containing available IDs for the user equipment; notifying the user equipment an ID in the ID table to be used through physical layer signaling or UE specific higher layer signaling; generating a random seed based on the notified ID; initializing a scrambling sequence by the random seed; and scrambling the signals with the initialized scrambling sequence. The method of the disclosure, by combining physical layer signaling and higher layer signaling, may notify the used group ID and the blind detection space to a UE, the blind detection for the UE is enabled and the signaling overhead is reduced.
