摘要： PROBLEM TO BE SOLVED: To measure the radio quality of a signal having a frequency different from that in communication while preventing transmission efficiency from lowering due to packet loss. SOLUTION: A resource allocating section 107 performs resource allocation scheduling based on the radio quality at the frequency of its own device informed from each mobile station device. A frequency switching determination section 108 selects such a mobile station device as the resource is not allocated as a result of scheduling and thereby a signal is not transmitted from a wireless network equipment as a mobile station device requiring frequency switching. A frequency switching instruction generating section 109 generates a frequency switching instruction for a mobile station device selected by the frequency switching determination section 108.

摘要： PROBLEM TO BE SOLVED: To provide a device and a method for demodulation which can reduce the power consumption although joint detection demodulation is used. SOLUTION: A service decision part 1 decides whether the number of spread codes to be used for communication currently carried out by a radio communication device of the local station is larger than a specified reference value and when so, a channel estimation part 2 generates a delay profile for all multiplex codes of only the local station. After an operation variable generation part 3 generates an operation variable according to the generated delay profile, an interference removal operation part 4 performs interference removal operation based upon the operation variable. When it is decided that the number of spread codes is less than the specified reference value, a delay profile for all multiplex codes including other stations is generated. An operation variable is generated on the basis of the generated delay profile and then interference removal operation is carried out on the basis of the operation variable.

摘要： PROBLEM TO BE SOLVED: To provide a base station apparatus and a mobile station apparatus capable of alleviating cell search processing. SOLUTION: The base station apparatus 100 is provided with: a frame configuration section 130 that forms a frame at least at either of the head and the end of which a pilot symbol is arranged, the pilot symbol resulting from multiplying a plurality of sequences included in a sequence set corresponding to a code group to which a base station scrambling code assigned to its own apparatus belongs; and a wireless transmission section 155 for transmitting the formed frame. Since the receiver side of the frame can detect frame timing on the basis of a position of the pilot symbol included in the frame and the base station scrambling code corresponds to the sequence set including the sequences and since objects are limited to the base station scrambling codes whose number is equal to combinations of the sequences included in the sequence set at most by detecting the sequences multiplied with the pilot symbol, the cell search processing can be alleviated.
