摘要： A reference signal of a user equipment to which a resource (LB#1) is allocated for a L1/L2 control signal, is allocated a resource (SB#1) that is closer on the time axis to the resource (LB#1), which the L1/L2 control signal is allocated, within the same frequency band as the L1/L2 control signal. A reference signal for CQI estimation, independent of a data signal and a L1/L2 control signal, is allocated a resource with which at least one of a reference signal for demodulation of a data signal and a reference signal for demodulation of a L1/L2 control signal is not transmitted at the same timing within the transmission band. The types of bandwidths of the reference signals multiplexed in a same short block within a same band are reduced, whereby restrictions as to the number of reference signal sequences that can be secured are diminished.

摘要： Provided is a wireless communication technique capable of supporting communication using a single component carrier, and communication using a plurality of component carriers. The communication using the plurality of carriers comprises a processing means for performing the signal processing in accordance with each of the carriers with respect to the common signal sequence used by the plurality of carriers. The present invention makes it possible to cope with the communication employing a single component carrier and the wireless communication employing a plurality of the component carriers. Further, PAPR of the reference signals can be made small because there is no possibility that the identical CAZAC sequence is used among the component carriers when a plurality of the component carriers are employed.

摘要： An object of the present invention is to reduce the amount of calculation performed in a mobile station and amount of information exchanged between a base station and mobile station in a mobile communication system where the base station autonomously assigns a scramble code. In the mobile communication system, the base station starts communication by using a predetermined initialization scramble code used only at its activation time. The mobile station positioned in a cell determines whether the scramble code identified upon cell search time is the initialization scramble code. Only when the scramble code is the initialization scramble code, the mobile station determines a candidate scramble code, determines whether the candidate scramble code is usable in communication, and notifies the base station of the control information including the determination result. Based on the control information, the base station determines a service scramble code to be used, from the candidate scramble codes, and applies the service scramble code to start communication.

摘要： The problem is that, in a mobile wireless system, when more than one frequency block composed of resource blocks that are consecutive on a frequency axis is assigned to one mobile station, the multi-diversity effect due to scheduling increases by the number of assigned frequency blocks being increased, but the overhead caused by the scheduling information increases. Accordingly, there is a tradeoff between the multi-diversity effect and the scheduling overhead. However, when the aforementioned tradeoff was considered with OFDM and SC-FDMA, the same fixed number of frequency blocks would have been used for all mobile stations. Accordingly, an optimization that takes into account the tradeoff between the multi-diversity effect and scheduling overhead has not been sufficiently achieved. In a wireless communication system, the maximum frequency block number, which is the maximum number of the aforementioned frequency blocks assigned to the same mobile station, is set based on system information, which is information pertaining to the base station installation environment and the mobile station or the mobile station's communication status, and the base station assigns no more resource blocks than the aforementioned maximum frequency block number.
摘要翻译： 问题在于，在移动无线系统中，当将由频率轴上连续的资源块组成的多个频率块分配给一个移动台时，由调度引起的多分集效应增加分配频率的数量 块增加，但由调度信息引起的开销增加。 因此，在多分集效应和调度开销之间存在折衷。 然而，当使用OFDM和SC-FDMA考虑上述权衡时，相同的固定数量的频率块将已经用于所有移动台。 因此，考虑到多分集效应和调度开销之间的折衷的优化尚未充分实现。 在无线通信系统中，基于作为与基站安装环境和移动台有关的信息的系统信息，设定作为分配给同一移动站的上述频率块的最大数量的最大频率块号 或移动台的通信状态，并且基站不再分配比上述最大频率块号更多的资源块。
