Method, apparatus and computer program for handling hybrid automatic repeat request failure
View Patent ↗A method by which a Node B is informed by a serving radio network controller that a medium access control-e reset is to be performed by a user equipment in communication with the Node B, so that the Node B can then provide failure indications of all hybrid automatic repeat request processes that are not decoded by the time of the medium access control-e reset. Corresponding equipment and software are also provided.
