Abstract
Systems and methods for outer loop Link Adaptation (LA) with bundled feedback are disclosed. In some embodiments, a method of operation of a radio access node in a cellular communications network to provide outer loop LA includes receiving, from a wireless device, a bundled feedback acknowledging reception of data by multiple Hybrid Automatic Repeat Request HARQ) processes at the wireless device. The method also includes, in response to receiving the bundled feedback, updating an outer loop LA parameter based on the number of HARQ processes in the HARQ processes and/or a metric indicative of channel correlation for a channel from the radio access node to the wireless device.
