摘要： Allocation of cell IDs in a cellular communication system includes determining a candidate allocation pattern of primary and secondary synchronization signal sequences for a candidate set of two or more cells. A performance metric is applied to the candidate allocation pattern to ascertain a performance indicator for the candidate allocation pattern, wherein the performance indicator indicates a quality of positioning performance for the candidate set of two or more cells. Cell-specific positioning performance for each cell in the candidate set of cells can be considered to derive the performance indicator of the candidate allocation pattern. If the performance indicator indicates acceptable positioning performance, primary and secondary synchronization signal sequences are allocated to respective ones of base stations corresponding to the two or more cells in accordance with the candidate allocation pattern. Otherwise, the process is repeated for a different candidate allocation pattern.

摘要： The present invention relates to methods and arrangements in a multi-carrier system. It also assumes independent DRX (Discontinuous reception) functionality on respective component carriers and the possibility for one carrier, e.g. the anchor carrier to initiate a change of DRX state for another component carrier. The basic concept of the present invention is to introduce a new "dormant" state in the DRX logic, whereby the dormant state can be used for non-anchor carrier components. The dormant DRX state implies that a carrier of a UE having this state is not required to monitor system signaling. In embodiments of the present invention this new state is introduced for a particular component carrier (e.g. non-anchor component carrier) for a UE operating in a multi-carrier system, and how to perform the transitions to and from the dormant DRX state implicitly, e.g. based on configured timer(s) for the component carrier or explicit signaling in a different (e.g. anchor) component carriers.

摘要： A wireless communication receiver performs robust cell searching, excluding interference due to UL transmissions from other UE, by qualifying the output of a matched filter with a metric indicative of the momentary signal-to-noise ratio (SNR). The momentary SNR metric is derived over the same amount of samples as the length of the matched filter. By discarding filter outputs during low momentary SNR, synchronization interference from UL transmissions is avoided. The momentary SNR metric and filter outputs are efficiently calculated, with only a few states and operations, compared to a conventional tapped delay line filter implementation. A limited list of cell candidates is populated, with information on correlation, timing, cell identity within cell group, and SNR metric for the K strongest candidates with respect to the matched filter correlation values. This list is used for later cell search stages, where a secondary synchronization channel is decoded.
