CONFIGURING MEASUREMENT REFERENCE SIGNALS FOR MIMO |
| 摘要 |
Systems and methods relating to 6-port and/or greater than 8-port Channel State Information Reference Signal (CSI-RS) configurations are disclosed. In some embodiments, a method of operation of a radio access node in a cellular communications network comprises configuring a plurality of CSI-RS ports for a wireless device, where the plurality of CSI-RS ports is six CSI-RS ports, ten CSI-RS ports, twelve CSI-RS ports, fourteen CSI-RS ports, or sixteen CSI-RS ports, depending on the embodiment. The method further comprises transmitting CSI-RS on at least a subset of the plurality of CSI-RS ports configured for the wireless device. In this manner, support for, e.g., an increased number of antenna ports and/or support for two-dimensional (2D) antenna arrays is provided. |
