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. Corresponding devices, computer programs and radio access nodes adapted to carry out the methods provided are also disclosed.

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.
摘要翻译：公开了用于多输入和多输出（MIMO）秩降级以改善下行链路吞吐量的系统和方法。一种无线电接入节点的操作方法包括确定对于无线设备的空间多路复用下行链路传输的并行信道之间的不平衡大于不平衡阈值和/或并行信道随时间推移的否定确认（NACK）速率由无线设备报告的空间多路复用下行链路传输大于NACK速率阈值。该方法还包括响应于确定并行信道之间的不平衡大于不平衡阈值和/或NACK速率大于NACK速率阈值，对下一个下行链路传输执行快速降级，由此排列从无线设备报告的等级指标降低到一些较低的等级。降低等级可以提高下行链路吞吐量。
