Abstract
A receiver includes a tunable receiving chain, configured to receive a subframe header when tuned to a first receiving bandwidth; a decoder, configured to decode an allocation information from the subframe header, the allocation information indicating an allocation of a plurality of resource blocks in the subframe; and a controller, configured to derive a second receiving bandwidth from the allocation information and to tune the receiving chain to the second receiving bandwidth.
Claims18
A receiver, comprising:
- a tunable receiving chain, configured to receive an allocation information indicating an allocation of a plurality of resource blocks over a first receiving bandwidth;
- and
- a controller, configured to derive a second receiving bandwidth from the allocation information and to tune the receiving chain to the second receiving bandwidth;
- wherein the controller is configured to tune the receiving chain to the second receiving bandwidth if a difference between the first receiving bandwidth and the second receiving bandwidth is above a threshold, and not tune the receiving chain to the second receiving bandwidth if the difference between the first receiving bandwidth and the second receiving bandwidth is below the threshold.

A receiver, comprising:
- a tunable receiving chain, configured to receive an allocation information over a first receiving bandwidth, the allocation information indicating an allocation of a plurality of resource blocks via a downlink control channel;
- a controller, configured to derive a second receiving bandwidth from the allocation information and to tune the receiving chain to the second receiving bandwidth;
- and
- a phase estimator, configured to estimate a phase of the allocation information based on reference symbols of a first slot when the receiving chain is tuned to the first receiving bandwidth and configured to reestimate the phase based on reference symbols of a second slot when the receiving chain is tuned to the second receiving bandwidth.

A receiver, comprising:
- a tunable receiving chain, configured to receive an allocation information over a first receiving bandwidth indicating an allocation of a plurality of resource blocks in a first subframe;
- and
- a controller, configured to derive a second receiving bandwidth from the allocation information and to tune the receiving chain to the second receiving bandwidth;
- wherein the receiving chain is configured to receive a plurality of subframes following the first subframe;
- wherein the controller is configured to tune the receiving chain to the second receiving bandwidth based on an inter subframe scheduling information which indicates a scheduling of the plurality of subframes,
- wherein the controller is configured to tune the receiving chain to the second receiving bandwidth if a difference between the first receiving bandwidth and the second receiving bandwidth is above a threshold.
