    摘要: A wireless communication terminal apparatus wherein the occurrences of inter-sequence interferences between cells can be reduced. In this apparatus, a sequence number deciding part (105) has a table in which the sequence numbers of a plurality of Zadoff-Chu sequences having different sequence lengths are associated with the sequence group numbers of a plurality of sequence groups into which the Zadoff-Chu sequences are grouped and with the transmission bandwidths of reference signals. In accordance with a sequence group number and a transmission bandwidth both received from a decoding part (104), the sequence number deciding part (105) refers to the table to decide the sequence number of a Zadoff-Chu sequence. In the table of the sequence number deciding part (105), the intervals of the sequence numbers of the Zadoff-Chu sequences used for the reference signals are established in accordance with the sequence lengths.

    摘要: A sequence allocating method and apparatus wherein in a system where a plurality of different Zadoff-Chu sequences or GCL sequences are allocated to a single cell, the arithmetic amount and circuit scale of a correlating circuit at a receiving end can be reduced. In ST201, a counter (a) and a number (p) of current sequence allocations are initialized, and in ST202, it is determined whether the number (p) of current sequence allocations is coincident with a number (K) of allocations to one cell. In ST203, it is determined whether the number (K) of allocations to the one cell is odd or even. If K is even, in ST204-ST206, sequence numbers (r=a and r=N−a), which are not currently allocated, are combined and then allocated. If K is odd, in ST207-ST212, for sequences that cannot be paired, one of sequence numbers (r=a and r=N−a), which are not currently allocated, is allocated.

According to these apparatus and method, a signature table storing part (103) that stores a table including a plurality of signatures obtained by classifying the magnitudes of propagation loss levels into levels in accordance with the distances from a base station, associating preamble detection window widths with those levels as classified, and by circularly shifting the pattern of a detection window signature #n corresponding to a signature #n to generate a signature #n+1. A signature selecting part (104) selects, based on the magnitude of a propagation loss level outputted by a propagation loss level determining part (102), one of the corresponding signatures from the signature table storing part (103) at random.

    摘要: Provided is a radio communication mobile station device capable of preventing a transmission delay when a transmission data amount is increased in a radio communication system where persistent scheduling is performed. In this device, an MCS selection unit (104) selects a first MCS if the transmission data amount accumulated in a buffer of a data control unit (105) is smaller than a threshold value and selects a second MCS having a higher MCS level than the first MCS if the transmission data amount is not smaller than the threshold value. Thus, in a mobile station (100), data encoded and modulated according to the first MCS is transmitted during a normal state when the transmission data amount is small, and data encoded and modulated according to the second MCS having a higher MCS level than the first MCS is transmitted when the transmission data amount is increased to a large amount.
