20120252446 | Fast Radio Access Technology Detection for Cell Search - Methods and apparatus are provided for detecting the radio access technology (RAT) employed in a received signal prior to performing a cell search. The RAT detection method may be used to identify the most likely RAT employed for each candidate frequency identified in an initial frequency scan. Once the most likely RAT is identified, the mobile communication device can then attempt synchronization according to the procedures for the most likely RAT. Identifying the RAT prior to the cell search reduces the number of synchronization attempts and, consequently, the time needed to perform the cell search. | 10-04-2012 |
20130100880 | Power Reduction for Correlated Carriers in a Cellular Communication System - A wireless communication transmitter configured to transmit a multi-carrier signal, the multi-carrier signal being an aggregation of two or more separately modulated carriers occupying distinct frequency regions is operated by obtaining a baseline multi-carrier metric indicative of an amount by which a multi-carrier signal's maximum transmit power should be reduced from a pre-determined nominal maximum to satisfy a predetermined out-of-band emission requirement when different scrambling codes are used on all carriers that are combined to create the multi-carrier signal. A compensating metric adjustment value that compensates for an estimation error that results from use of a same scrambling code on two or more of the carriers is estimated. A final multi-carrier metric is obtained by adjusting the baseline metric by an amount based on the compensating metric adjustment value when the same scrambling code is used on the two or more of the carriers. | 04-25-2013 |
20140092947 | Adaptive Smoothing of Channel Estimates - Techniques for directly adapting the parameters of a smoothing filter used for channel estimation to the current velocity and signal-to-noise ratio (SNR) situation. An example method begins with a plurality of channel response measurements. For each of a first subset of a set of pre-determined filter responses, the channel measurement samples are filtered to obtain a corresponding set of estimated channel response samples. Next, for each set of estimated channel response samples, a corresponding set of ordered residuals are calculated from the channel measurement samples. Each set of ordered residuals is evaluated to determine a measure of correlation among the ordered residuals, and an updated filter response is selected from a second subset of the set of pre-determined filter responses, based on this evaluation, for use in demodulating a received signal. | 04-03-2014 |
20140194121 | Handover Event Prioritization - A method, implemented by a communications device, for communicating wireless handover events, the communications device being associated with a serving cell of a cellular communications network, the method comprising: determining, based on at least one or more first measurement results indicative of cell quality parameters of a plurality of cells of the cellular communications network, a first handover event associated with a first one of the cells; initiating communication of a first handover message indicative of the determined first handover event to a network entity of the cellular network; determining, based on at least one or more second measurement results, 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; determining a priority order for at least a subset of the pending handover events, wherein the subset comprises handover events associated with different cells. | 07-10-2014 |
