摘要： The present invention relates to a method for determining link adaptation parameters for a wireless device. The method is performed in a first radio network node of a wireless communication system. The first radio network node hosts a first cell serving the wireless device. The wireless device is interfered by a second cell. The method comprises predicting (410) a future position of the wireless device. The method also comprises estimating (420) a first radio channel quality value for the wireless device in the predicted future position, based on: pathloss values related to the wireless device in the predicted future position for the first and the second cell respectively; and a transmission power of the second cell. The method further comprises determining (430) link adaptation parameters for the scheduling of the wireless device in the future position using the estimated first radio channel quality value.

摘要： Relay reporting in a wireless network is implemented by efficiently allocating radio resources based on the nature or criticality of the type of relay report. According to an embodiment, a method of communicating with a relay located in a wireless network includes instructing the relay when to transmit reports based on a mapping of different categories of relay reports to one or more different reporting schemes. Reports are received from the relay based on the relay report category and the corresponding reporting scheme. According to another embodiment, a method of reporting information from a relay to a network node of a wireless network includes generating different categories of reports at the relay for transmission to the network node. A reporting scheme associated with each report category is identified and each report is transmitted to the network node in accordance with the reporting scheme identified for the corresponding report category.
