20120182958 | Reconfiguration of Active Component Carrier Set in Multi-Carrier Wireless Systems - In a multi-carrier wireless system, potential problems from reconfiguring mobile station resources to accommodate changes in component-carrier configuration are mitigated by inserting a guard period each time the configuration of component carriers changes, so that transceiver reconfiguration can be carried out without interfering with ongoing transmission. A base station is configured to transmit data to a mobile station according to a first configuration of two or more component carriers, to determine that a change of configuration to a second component-carrier configuration is required, and to signal the change of configuration to the mobile station, using the first configuration of component carriers. The base station then refrains from transmitting data to the mobile station during a pre-determined guard interval of at least one transmission-time interval subsequent to the signaling of the change of configuration. After the guard interval, data is transmitted to the mobile station according to the second component-carrier configuration. | 07-19-2012 |
20120307660 | Technique for Performing Physical Layer Measurements - The present disclosure relates to a technique for performing physical layer measurements on a frequency resource relative to other frequency resources in a telecommunications system operable to communicate over multiple frequency resources. A method aspect of this technique includes determining that a mobile terminal is to perform a physical layer measurement with regard to a first frequency resource, determining if there is data to be communicated over one or more second frequency resource(s) within a time period wherein the first frequency resource is distinct from the second frequency resources: if it is determined that there is no data to be communicated over the second frequency resource(s) within the time period, performing the physical layer measurement on the first frequency resource and forming a quality measure of the first frequency resource based on the physical layer measurement; or if it is determined that there is data to be communicated over the second frequency resource(s) within the time period, modifying the physical layer measurement and forming a quality measure of the first frequency resource based on the modified physical layer measurement. | 12-06-2012 |

20130177113 | Correction of Imbalances in a Complex Intermediate Frequency Mixer - A complex intermediate frequency mixer (IFM) for frequency translating a received complex intermediate frequency, IF, signal, wherein the received complex IF signal comprises at least two frequency bands located at upper-side and lower-side of 0 Hz, is provided. The complex intermediate frequency mixer comprises a first, second, third and fourth mixer (M | 07-11-2013 |
20130208776 | Test Signal in Receiver - The invention proposes a way of inserting an analog test signal during normal reception into analog blocks of an OFDM receiver in such a way that the reception is either not corrupted at all, or only very little. This is achieved either by inserting the analog test signal in time or frequency where it does not corrupt the received signal, or by accounting for the interfering analog test signal in the decoding process. | 08-15-2013 |
20130266093 | Methods and Receiver for Positioning of Clock Related Spurious Signals - Methods and a receiver of positioning a spurious signal for reducing the impact of the spurious signal on a received Orthogonal Frequency Division Multiplexing, OFDM signal, are presented. The method comprises determining the frequency of a spurious signal (steps | 10-10-2013 |
20130278321 | Method and Apparatus for Mixer-Based Harmonic Rejection - In one aspect, the present invention exploits the termination conductances of a time-discrete harmonic mixer as another degree of freedom in configuring the mixer to meet given harmonic rejection performance requirements while using reduced number of unit cells. The values of these termination conductances are purposefully configured to introduce a desired non-linearity in quantization of the mixer transconductance by the unit cells. The non-uniform quantization produces a non-linear fitting of the transconductance levels to the transconductance points defining the target sinusoidal waveform. As a consequence of its termination conductance configuration, the contemplated mixer achieves levels of harmonic rejection with that would not be met if the reduced number of unit cells operated with uniform quantization. As a further advantage, the manipulated conductance values generally are lower than those used in conventional designs, e.g., on par with the maximum conductance of the mixer, as provided by mixer's set of unit cells. | 10-24-2013 |
