摘要： A cell searching procedure is modified to enable a user terminal to determine whether a detected signal originates in a known cell or a new cell having the same cell identifier as the known cell. When a signal is detected, the user terminal determines the cell identifier and timing of the detected signal. If the cell identifier matches a known cell and the timing is outside the timing window of the known cell, the user terminal compares detected signal with a corresponding received signal received from the known cell having the same cell identifier as the detected signal source. The user terminal determines, based on said comparison, whether the detected signal is from the known cell or a new cell.

摘要： A user equipment (UE) in a cellular telecommunications system is able to detect the uplink/downlink configuration of a detected neighboring cell by receiving a signal from the neighboring cell. A characteristic of the received signal is detected and used as an indicator in a blind detection process to identify one or more downlink slots in the received signal. Known pilot signals in the identified one or more downlink slots can then be used to obtain a signal power measurement of the received signal. The blind detection process is also capable of detecting whether a slot of a neighboring cell's signal is a downlink unicast slot or a Multicast-Broadcast Single Frequency Network slot.

摘要： A multi-branch OFDM receiver combines diversity signals received over different receiver branches using interference rejection combining. The receiver generates first channel estimates associated with a serving base station, second channel estimates associated with at least one non-serving base station, and a time offset between the serving base station and non-serving base station. The receiver computes a noise covariance matrix based on the second channel estimates and the time offset, and then combines the diversity signals received over different branches using the first channel estimates and the noise covariance matrix.

摘要： A user equipment is operated in a mobile communications system, wherein a network part of the mobile communications system is capable of operating in a synchronized mode or in an asynchronous mode. Operation includes recording timing information about a periodically occurring signal received from a neighboring cell. The recorded timing information is used in a blind detection proc\ ess that ascertains whether the network part of the mobile communications system is operating in the synchronized mode or in the asynchronous mode by detecting at least whether the periodically occurring signal received from the neighboring cell occurred within a predetermined window of time of a corresponding periodically occurring signal received from a serving cell. The detected operating mode of the network part of the mobile communications system is used for controlling subsequent operation of the user equipment.

摘要： Channel estimation is performed by user equipment operating in a mobile communications system. Estimation involves receiving a signal and analyzing it to detect a signal component from a neighboring cell. Depending on outcome, one or both of the following are determined: whether a power level of the signal component from the neighboring cell exceeds a power threshold level; and whether a difference between timing parameters of the neighboring cell?s signal component and that from a serving cell is less than a timing threshold level. If the power level of the neighboring cell?s signal component exceeds the power threshold level and the difference between the timing parameters of the signal components from the neighboring cell and that of the serving cell is less than the timing threshold level, then a joint channel estimation process is performed. Otherwise, a single channel estimation process is performed.

摘要： An apparatus, and a method performed by the apparatus, including a terminal with a front end receiver and analog filter (AF) operable throughout a bandwidth that is large enough to cover the total bandwidth used by different access technologies that the terminal supports. The terminal is operable to simultaneously extract from the output of a single front end receiver and AF the carrier frequencies and bandwidths of the different access technologies. This permits cell evaluation activity and an ongoing communication session to be conducted simultaneously with different access technologies on different bandwidths within the bandwidth of the analog filter and without interruption of the communication session.
