Adaptive scheme for lowering uplink control overhead

摘要

The present invention is related to methods, apparatuses, systems and computer software for determining an amount of physical resources for downlink transmission, and allocating uplink physical resources for transmission of data-non-associated control signaling based at least on the amount of physical resources for downlink transmission. The amount of physical resources for downlink transmission comprises an amount of downlink control signaling. The present invention further relates to a framework for mapping the dedicated uplink control channels directly to single physical resource blocks. The framework is able to efficiently shift physical resources to and from the uplink control channel for ACK/NACK reports, in a data-non-associated control signaling scheme and on a per subframe basis. The present invention is also concerned with scheduler, for example an eNodeB scheduler, which uses its scheduling history and knowledge of user equipment capabilities to increase utilization of uplink resources.
