Title
(EN) Downlink transmission coordinated scheduling
Abstract
(EN)

A method of coordinated scheduling of a downlink transmission flow from a first radio network node to a user equipment UE in a second radio network node. The method includes scheduling the downlink transmission flow so that the in-sequence delivery of the received data blocks can be kept in an acceptable level in the UE by adjusting a scheduling priority of the downlink transmission flow in the second radio network node. The method may further include estimating one or more buffer-related parameters based on buffered data for the downlink transmission flow from the first radio network node, and determining, based on the estimated one or more buffer-related parameter and/or one or more parameters associated with the operation status of the second radio network node, if the in-sequence delivery of the received data blocks to higher layers can be in an acceptable level in the UE.
