Patent ID: 8797922

Claim:
A method for wireless communications, comprising: determining a set of decoding candidates for each of a plurality of aggregation levels for control information transmission to a node; determining a set of ambiguous decoding candidates across the set of decoding candidates for each of the plurality of aggregation levels, wherein a first decoding candidate of aggregation level m is in the set of ambiguous decoding candidates if there is at least a second decoding candidate of aggregation level n, wherein m is not equal to n, which has a same starting control channel element (CCE) index as the first decoding candidate; transmitting control information to the node using the first decoding candidate; and assigning downlink (DL) resources for data transmission corresponding to the control information, wherein the assigned DL resources are based on the first decoding candidate and the set of ambiguous decoding candidates, wherein the first decoding candidate is fully contained in the assigned DL resources and at least a portion of the second decoding candidate is outside the assigned DL resources.
