Abstract
The present invention relates to a method and mobile terminal for performing a data allocation process for scheduled data, non-scheduled user data and non-scheduled control data obeying restrictions on the resource utilization defined by a scheduling grant and at least one non-scheduled grant. Further, the invention relates to a method for transmitting control signaling from a network entity in a radio access network of a mobile communication system controlling the radio resources of mobile terminals to at least one of said mobile terminal and the network entity in a radio access network. In order to reduce the delays to control signaling implied by a conventional HARQ process restriction mechanism the present invention suggests a new categorization of uplink data into scheduled data, non-scheduled user data and non-scheduled control data and a new HARQ process restriction mechanism disabling certain HARQ processes for non-scheduled user data only.
