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 a subframe header of a first subframe 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 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 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 a subframe header of a first subframe when tuned to a first receiving bandwidth, wherein the first subframe comprises a first slot and a subsequent second slot;
- 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 first subframe;
- 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 subframe header based on reference symbols of the first slot when the receiving chain is tuned to the first receiving bandwidth and configured to reestimate the phase based on reference symbols of the second slot when the receiving chain is tuned to the second receiving bandwidth.
A receiver, comprising:
- a tunable receiving chain, configured to receive a subframe header of a first subframe when tuned to a first receiving bandwidth, wherein the first subframe comprises a first slot and a subsequent second slot;
- 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 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 receiver comprises a scheduling circuit, configured to provide inter subframe scheduling information which indicates a scheduling of the plurality of subframes with respect to time;
- and
- wherein the controller is configured to tune the receiving chain to the second receiving bandwidth based on the inter subframe scheduling information.
