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.

摘要： This disclosure relates to techniques for synchronization signals. The synchronization signal comprise a primary synchronization signal (PSS) generated based on a PSS sequence and a secondary synchronization signal (SSS) generated based on an SSS sequence. The SSS sequence may be generated based on a first sequence corresponding to a first cyclic shift and a second sequence corresponding to a second cyclic shift. The first cyclic shift and the second cyclic shift are associated with Cell ID. The PSS sequence may be generated based on one of the first and the second sequences.

摘要： Provided are a base station device and a mobile station device, which can lighten a cell-search processing. The base station device includes a frame constitution unit for forming a frame, in which a pilot symbol multiplied by a base station scrambling code and a plurality of sequences contained in the corresponding sequence set is arranged in at least the head or tail, and a radio transmission unit for sending the formed frame. On the receiving side, the frame timing can be detected from the position of a pilot symbol contained in that frame. Since the base station scrambling code and the sequence set containing the sequences are made to correspond to each other, candidates can be narrowed to at most the base station scrambling codes of the number of the combinations of the sequences contained in the sequence set, by detecting the sequences multiplied by the pilot symbol.

摘要： A disclosure of the present specification provides a method for detecting a discovery signal. The method is a method for detecting discovery signals from a plurality of transmission points (TP) using the same physical cell identifier (PCID) and may comprise the steps of: determining scrambling identifiers of the discovery signals for the plurality of transmission points on the basis of the PCID which is commonly used by the plurality of transmission points and resource elements (REs) of the discovery signals transmitted from the plurality of transmission points; and demodulating the discovery signals on respective positions of the resource elements using the determined scrambling identifiers to detect the discovery signals.

摘要： A method in a first radio network controller, RNC, (105, 405) for handling a reuse of a scrambling code in a cellular network (100) is provided. The first RNC (105, 405) defines a set of scrambling codes. Each scrambling code in the defined set is locally reused by at least two cells in the cellular network (100). The first RNC (105, 405) receives a measurement report from a user equipment (180). The measurement report is related to a scrambling code that is comprised in the defined set of scrambling codes. The first RNC (105, 405) determines that the reported scrambling code is comprised in the defined set of scrambling codes. The first RNC (105, 405) initiates, based on the determination, a process for identifying, among the at least two cells in which the reported scrambling code is locally reused, an originating cell from which the reported scrambling code originates.

摘要： A receiver 10 and method in the receiver for cell search to find an actual base station having a carrier frequency in a radio communications network 1. The receiver detects a first signal representative of a base station 12, 14, 16, 18 by performing slot synchronisation, frame synchronization, cell identification, measurement of a signal quality of the first signal and comparison of the measured signal quality with a first threshold value. When a first signal having a signal quality that is greater than the first threshold value has been detected, the receiver searches for at least one second signal representative of a base station for at least one frequency offset comprised in a set of offsets S3. Further, when one or more second signals are detected, the receiver selects the signal with the highest signal quality, and detects a broadcast radio channel representative of a base station for the selected signal.
