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.

摘要： A radio network controller is operable in both a unicast signaling mode and a bi-cast signaling mode. In unicast signaling mode, the radio network controller is operable to send radio resource control signals to a mobile station through a serving cell. The radio network controller is operable to go into bi-cast signaling mode during a hard handover. In the bi-cast signaling mode, the radio network controller is operable to send radio resource control messages to the mobile station through both the current serving cell and a target cell. The mobile station is configured to listen to both the current serving cell and the target cell for radio resource control messages. User data, however, is transmitted only from the current serving cell to the mobile station.

摘要： In a mobile communication network comprising a pico base station and macro base station with overlapping coverage areas, the pico base station transmits a supplemental synchronization signal to enable synchronization when the mobile terminal is operating within a link imbalance zone. The supplemental synchronization signal is transmitted using different time, frequency, and/or code resources from the primary and/or secondary synchronization signals to differentiate and separate the supplemental synchronization signals.

摘要： In one embodiment, a method of scheduling transmissions for a base station in a multi-carrier wireless communication network comprises scheduling initial transmissions of data packets for one or more users on a first carrier, without reserving scheduling capacity on the first carrier for retransmissions. Doing so increases the scheduled capacity of the first carrier for initial transmissions. The method further includes scheduling retransmissions, as needed, for given ones of the data packets on one or more second carriers. The method allows more traffic to be scheduled on the first carrier, meaning that multi-carrier transmissions are less frequently needed to convey all of the traffic targeted to one or more receivers. Those receivers therefore spend more time operating with a reduced receiver bandwidth (as compared to the bandwidth required for receiving more than one carrier), which reduces operating power.

摘要： A radio network node and a method therein, for controlling usage of RAT and bandwidth in a radio communication system. The method includes allocating a first RAT to a first bandwidth, allocating a second RAT to a second bandwidth, and allocating the first and second RATs to a third bandwidth comprising a part of the first bandwidth and/or a part of the second bandwidth. When the first RAT has a higher load than the second RAT, the method includes transmitting data for the first RAT in both the first third bandwidths, transmitting data for the second RAT only in the second bandwidth, and transmitting common control signals and/or pilot signals for the first RAT in the first and third bandwidths.

摘要： In a method and a mobile communications receiver for processing signals from a first cell and a second cell a timing of the signal from the first cell and the second cell is obtained. A timing difference (δ) between the timings of signals from the first and the second cell is determined and based on that a timing (κ) for a window for discrete Fourier transform, DFT, processing is adjusted.

摘要： A method of scheduling wireless data transmissions between a mobile terminal and a base station using multiple system carrier signals is disclosed. The method comprises receiving (101) in the mobile terminal information from the base station indicating available system carriers and transmitting from the mobile terminal information indicating the terminal's capability to handle non-contiguous system carriers; detecting (102) at least one dynamic parameter indicative of the terminal's current capability to handle non-contiguous system carriers; determining (103) from the dynamic parameter whether a situation has occurred in which the terminal's capability to handle non-contiguous system carriers has changed; transmitting (104), in such case, a connection release request to the base station; and transmitting (105) a connection setup request and information indicating the terminal's changed capability to handle non-contiguous system carriers to the base station. Thus system carriers that can be handled by the terminal in the present situation can be allocated.

摘要： A adaptive method implemented by a mobile station improves the likelihood of detecting control messages transmitted to the mobile station in band on a shared downlink traffic channel. When the mobile station expects a control message to be transmitted on the shared downlink traffic channel, the mobile station may adapt the receiver configuration and/or receiver parameters to reduce a likelihood of missed detection of control messages. In one embodiment, the mobile station is configured to adjust a correlation threshold used for said scheduled transmission detection to reduce the likelihood of a missed detection.
