Abstract: Provided is a radio communication base station device which can prevent lowering of use efficiency of a channel communication resource for performing a frequency diversity transmission when simultaneously performing a frequency scheduling transmission and the frequency diversity transmission in a multicarrier communication. In the device, a modulation unit (12) executes a modulation process on Dch data after encoded so as to generate a Dch data symbol. A modulation unit (22) executes a modulation process on the encoded Lch data so as to generate an Lch data symbol. An allocation unit (103) allocates the Dch data symbol and the Lch data symbol to respective subcarriers constituting an OFDM symbol and outputs them to a multiplexing unit (104). Here, when a plurality of Dch are used for a Dch data symbol of one mobile station, the allocation unit (103) uses Dch of continuous channel numbers.

Abstract: In a wireless communication base station device, a modulation unit carries out modulation processing for Dch data after coding to generate a Dch data symbol. A modulation unit carries out modulation processing for Lch data after coding to generate an Lch data symbol. An allocation unit allocates the Dch data symbol and Lch data symbol to each sub-carrier composing an OFDM symbol and outputs the allocated sub-carrier to a multiplex unit. In this case, the allocation unit allocates the Dch data symbol to a plurality of resource blocks where one Dch is arranged at an interval equal to integral multiples of the number of resource blocks composing a resource block group.

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: The invention relates to a method, apparatus and system for configuring control channels in a mobile communication network and a mobile station. In order to suggest another improved scheme for configuring control channels, in particular control channels related to the transmission of user data the invention suggests aligning the size of the control channel information of different formats to an equal number of coded control channel information bits and/or modulation symbols for each control channel. The control channels may comprise scheduling related control information. According to another aspect of the invention, the size of the control channel information is aligned by means of modulation and/or coding, however the control channel information is aligned to one out of a set of numbers of coded control channel information bits and/or modulation symbols for each control channel.
