Scheduling with hidden rate request
First Claim
1. A scheduling device for scheduling data transmission over a plurality of channels in a data network, said device comprising:
- a monitoring unit configured to monitor a predetermined parameter indicating a channel capacity in a received data stream of at least one of said plurality of channels; and
a scheduling unit configured to determine a request for change of a maximum channel capacity allocated to said at least one of said plurality of channels, if a value of said monitored predetermined parameter falls outside a predetermined allowed range.

Abstract
The present invention relates to a terminal device and to a scheduling method and device for scheduling data transmission over a plurality of channels in a data network. A predetermined parameter, e.g. a TFC value, indicating a channel capacity in a received data stream of at least one of the plurality of channels is monitored, and a request for change of the maximum channel capacity allocated to the at least one of the plurality of channels is determined, if the value the monitored predetermined parameter falls outside a predetermined allowed range. The terminal device is configured to set a predetermined parameter indicating a channel capacity to a value outside the predetermined allowed range in order to request a change of the maximum channel capacity. Thereby, an explicit capacity request signaling from the data source to the scheduling functionality can be avoided without introducing additional latency, and physical layer resources can be increased for improved data transmission.
