A METHOD OF OPERATING A COMMUNICATION DEVICE AND SYSTEM, A COMMUNICATION DEVICE AND A SYSTEM INCLUDING THE COMMUNICATION DEVICE

摘要

A communication system, such as UMTS, comprises a scheduler (12) in a first station (PS) which is able to control a user equipment (UE1, UE2). The scheduler when operating in a data transmission mode, such as HSUPA (High-Speed Uplink Packet Access) controls the user equipment with combinations of absolute grants (AG) and relative grants (RG). The relative grants serve to adapt a transmission parameter relative to a reference value. The reference value for the relative grant is selected dependent on a property of one or more of the grants. Such a property may comprise the absolute grant being an all process grant or a single process grant.
