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： A technique for managing activity states of at least two subscriptions in a terminal device is described. A method implementation of this technique performed in the terminal device comprises the steps of monitoring whether a first subscription is to transit or has transit from a first active state to a second active state while at least one second subscription is in a detached state, wherein the second active state is associated with a lower terminal activity than the first active state, if the result of the monitoring step is affirmative, waiting for a predetermined period of time, upon elapse of the predetermined period of time, if the first subscription is still in the second active state, triggering a transition of the first subscription from the second active state to an inactive state and initiating for the at least one second subscription a transition from a detached state to an inactive state.

摘要： Channel estimation is performed in a mobile communications system. In order to reduce the computational load, and thereby decrease power consumption, a polynomial expression is used to approximate a Minimum Mean Squared Error (MMSE) based channel estimator with respect to Doppler and SIR variations. A lookup table may be used to supply coefficients for the polynomial expression. In another aspect of the invention, coefficients for the polynomial expression may, themselves, be approximated by a second polynomial expression.

摘要： To communicate wireless handover events, a communications device associated with a serving cell of a cellular network determines, based on at least one or more first measurement results indicative of cell quality parameters of a plurality of cells of the cellular network, a first handover event associated with a first one of the cells, initiates communication of a first handover message indicative of the determined first handover event to a network entity of the cellular network, and, based on at least one or more second measurement results, determines a plurality of further handover events associated with respective ones of the cells, resulting in a plurality of pending handover events waiting to be communicated to a network entity of the cellular network. The communications device also determines a priority order for at least a subset of the pending handover events. The subset includes handover events associated with different cells.

摘要： A method of estimation of harmonic distortion level for a radio receiver operative in a cellular communication system enabled to receive signals from transmitters of one or more cells is disclosed. The method comprises measuring, within a bandwidth of operation, a total received signal power; measuring, within the bandwidth of operation, a received signal power of signals received from the one or more cells, respectively; and estimating a level of harmonic receiver distortions by: determining whether a fraction of the total received signal power and a theoretical noise floor is below or above a first threshold; or determining whether a remaining part of the total received signal power, said remaining part not including said fraction, is above or below a second threshold. A such radio receiver, and a computer program for implementing the method are also disclosed.
