摘要： A method and apparatus for frequency offset estimation exploits the differences in reference symbol timing for different channels to resolve ambiguities in the frequency offset estimation. Based on the initial frequency offset estimates, a hypothesis table is constructed providing hypothesized frequency offsets for each channel for a plurality of possible offset regions. An error metric for each offset region is calculated based on the difference of the hypothesized frequency offsets. The set of hypothesized frequency offsets that minimize the error metric is selected as the final frequency offset estimates.

摘要： Embodiments of a method for measurement of electromagnetic field strength at a point of interest in a coverage area of a 2-dimensional (2D) active antenna system (AAS). The 2D AAS transmits with a load factor of 100 percent. The 2D AAS sweeps a predefined range of azimuth and elevation angles, and azimuth and elevation directions which yield highest EMF at the point of interest are determined. First beamforming weights are determined based on the azimuth and elevation directions and the 2D AAS caused to apply the first beamforming weights. The 2D AAS sweeps a co-phasing angle from 0 to 360 degrees, and a co-phasing angle which yields highest EMF is determined. Second beamforming weights are determined based on azimuth and elevation directions and the co-phasing angle, and the 2D AAS caused to apply the second beamforming weights. The EMF strength at the point of interest is measured.

摘要： In one embodiment, a method of operating a radio access node is provided. The method comprises determining whether support from a secondary cell is required for a wireless device to communicate with the radio access node, and, in response to determining that support from the secondary cell is required, calculating a modified channel condition outer-loop value for the secondary cell; and using the modified channel condition outer-loop value in an initial activation decision step for the secondary cell. The initial activation decision step may comprise activating the secondary cell in response to determining that the sum of a device reported channel condition value and the modified channel condition outer-loop value is above an activation threshold.

摘要： Systems and methods for improved Physical Downlink Control Channel (PDCCH) Link Adaptation (LA) in carrier aggregation are disclosed. A method of operation of a radio access node includes transmitting multiple control messages to the wireless device via PDCCHs associated with corresponding serving cells of the wireless device, informing the wireless device of data transmissions to be transmitted to the wireless device via Physical Downlink Shared Channels of the corresponding serving cells and concurrently operating multiple Physical Uplink Control Channel (PUCCH) receivers on one serving cell during a Transmit Time Interval during which feedback from the wireless device indicative of reception of the data transmissions is expected, where each PUCCH receiver is capable of receiving a different format PUCCH message if necessary. The method also includes updating an outer loop LA parameter for each of the PDCCHs based on the determined PDCCH transmission status.

摘要： Systems and methods for Multiple-Input and Multiple-Output (MIMO) rank reduction to improve downlink throughput are disclosed. A method of operation of a radio access node includes determining that an imbalance between parallel channels of a spatial multiplexing downlink transmission to a wireless device is greater than an imbalance threshold and/or that a Negative Acknowledgement (NACK) rate over time for the parallel channels of a spatial multiplexing downlink transmission reported by the wireless device is greater than a NACK rate threshold. The method also includes, in response to determining that the imbalance between the parallel channels is greater than the imbalance threshold and/or that the NACK rate is greater than the NACK rate threshold, performing a fast rank reduction for a next downlink transmission whereby a rank is reduced from a rank indicator reported by the wireless device to some lower rank. Reducing the rank may improve downlink throughput.

摘要： Systems and methods for Secondary Cell (sCell) selection for wireless devices operating according to a carrier aggregation scheme in a cellular communications network are disclosed. In one embodiment, a network node in the cellular communications network obtains geographic signatures for a number of candidate sCells. The geographic signatures include a geographic signature for each candidate sCell that approximates a coverage area of the candidate sCell. The network node obtains position information for a wireless device and then selects one or more sCells for the wireless device from the candidate sCells based on the geographic signatures for the candidate sCells and the position information for the wireless device. The network node then configures the selected sCell(s) for use by the wireless device according to a carrier aggregation scheme. Using this process, sCell selection is performed, in some examples, without measurement gaps and without disabling an s-Measure parameter.
