摘要： Timing parameters and an identity of a particular one of a number of cell groups are indicated in a signal transmitted in a cellular communication system having a radio frame in a physical layer, the radio frame comprising a number of time slots. In a known one of the time slots, a synchronization signal, S 1 , is transmitted that comprises a pair of sequences (I) arranged in a first ordering. In another known one of the time slots, a synchronization signal, S 2 , is transmitted that comprises the pair of sequences (II) arranged in a second ordering. The selected pair of sequences is uniquely ident ified with the particular cell group, and the first ordering of the sequences is used only for transmission in the known one of the time slots, and the second ordering of the sequences is used only for transmission in said another known one of the time slots.

摘要： A first transceiver in a packet-based communications system is operated to achieve efficiencies. The transceiver comprises a receiver and a transmitter for bidirectionally communicating with a second transceiver. In various embodiments, data and control traffic scheduling enables several unrelated items to be bundled during single transmission and/or reception instances. In one aspect, receiver operation involves receiving a first signal from the second transceiver, the first signal requiring that return link information be sent to the second transceiver. A period of time during which the first transceiver can begin a bundled transmission of the return link information and initiating link information that is unrelated to the information carried by the first signal is determined. The bundled transmission of the initiating and return link information is begun during the determined period of time. Application of power sufficient to support reception and/or transmission can be limited to only when those components are used.

摘要： A method and apparatus adapted to adjust threshold values for initiating HO measurements based on terminal or user equipment (UE) performance. The threshold values for initiating the HO measurements and for executing the HO may be determined by the network. Prior to determining whether to proceed with these procedures, the thresholds are adjusted, based on the actual UE performance. This adjustment is achieved by applying an offset in dB that captures the effective SIR improvement of the advanced receiver compared to the standard receiver used to set the thresholds. The offset depends on, among other things, the receiver type used, the number of receiver antennas, the multi-path channel profile, the number of active radio links, and the services/connection modes that are currently active in the UE.

摘要： A mobile terminal can identify cellular control channels that can be received by the mobile terminal from a cellular system, by identifying a cellular control channel that can be received from a history list of cellular control channels that were previously received by the mobile terminal. A next cellular control channel that can be received by the mobile terminal then is scanned for, by skipping at least one cellular control channel that is adjacent the cellular control channel that was identified, based on channel allocation rules in the cellular system.

摘要： The invention offers a method of estimating the channel parameters of a co-channel interferer. Initial, rough estimates of the desired channel and of the desired data symbols are made, and a fraction of the estimated desired signal is subtracted from the received signal. The fraction depends on the uncertainty of the desired signal. The synchronisation position of the co-channel interferer is determined, which is used to reject the co-channel interference. In a pre-processing stage only rough estimates of the desired transmission channel and of the desired data symbols are needed. Consequently, a much faster convergence of the algorithm used for detecting the co-channel interference results. When the co-channel interference signal has been detected, it can be eliminated by any suitable method.

摘要： A cellular communication system has an air interface divided into frames, each consisting of sub-frames at least two of which are synchronization sub-frames. For each cell, different cell-related synchronization signals are transmitted to user equipments (UEs) in different synchronization signal sub-frames. The UE detects cell identities of first and second cells. Weights then control generation of weighted handover measurements made from the first cell's synchronization signals received during synchronization sub-frames, wherein each of the weights is a function of the cell identity of the first cell, the cell identity of the second cell, and which ones of the first and second cells' cell-related synchronization signals are transmitted in the respective one of the plurality of synchronization sub-frames during which the weight is applied. A filtered handover measurement, upon which a handover decision can be made, is generated from the weighted handover measurements.

摘要： A base station includes an emulation controller (20) configured to receive signals indicating that another base station in an active mode managing a cell, having a predetermined cell identity and coverage area, will go into an idle mode and no longer manage the cell, and to determine terminal activity in the cell. A baseband processing unit (18) is connected to the emulation controller (20) and configured to emulate the active mode of the other base station by taking over management of the cell, in at least part of its coverage area, using the same cell identity.
