| 发明名称 | Interference estimation resource definition and usage for enhanced receivers | ||
| 摘要 | At a wireless node in a wireless network, multiple interference estimation resources are received in a time-frequency resource space. The multiple interference estimation resources are resource elements in an assigned physical shared channel of the time-frequency resource space that do not contain physical shared channel data for the wireless node. An interference covariance matrix is determined from received signals on the multiple interference estimation resources. Symbol estimates are determined for a desired signal based in part by using the interference covariance matrix. Methods, computer programs and products and apparatus are disclosed. The techniques may be used for uplink, downlink, or D2D communications. | ||

| 主权项 | 1. A method, comprising: receiving, at a wireless node in a wireless network, configuration of a plurality of interference estimation resources in a time-frequency resource space, where the plurality of interference estimation resources are resource elements in an assigned physical shared channel of the time-frequency resource space that do not contain physical shared channel data for the wireless node; determining an interference covariance matrix from received signals on the plurality of interference estimation resources; and determining symbol estimates for a desired signal based in part by using the interference covariance matrix. | ||
