1. A method comprising:
- ranking a plurality of downlink control information (DCI) messages according to a first rank criterion;
ranking a plurality of allowable resource sets for each ranked DCI message according to a second rank criterion, wherein ranking according to the second rank criterion further comprises at least one of;
ranking, for each ranked DCI message, allowable resource sets for a particular ranked DCI message in ascending order according to a number of control channel elements (CCEs) required in each allowable resource set for the particular ranked DCI message; and
for any corresponding allowable resource sets for the particular ranked DCI message having a same number of control channel elements (CCEs);
ranking the corresponding allowable resource sets according to an index of a starting CCE for each corresponding allowable resource set or ranking the corresponding allowable resource sets randomly; and
allocating resources for each ranked DCI message based, at least in part, on whether particular resources, which are to be allocated for a particular ranked DCI message, are collided, at least in part, with previously allocated resources for one or more other DCI messages.

8. One or more non-transitory tangible media encoding logic that includes instructions for execution by a processor, wherein the execution causes the processor to perform operations, comprising:
-
ranking a plurality of downlink control information (DCI) messages according to a first rank criterion; ranking a plurality of allowable resource sets for each ranked DCI message according to a second rank criterion, wherein ranking according to the second rank criterion further comprises at least one of; ranking, for each ranked DCI message, allowable resource sets for a particular ranked DCI message in ascending order according to a number of control channel elements (CCEs) required in each allowable resource set for the particular ranked DCI message; and for any corresponding allowable resource sets for the particular ranked DCI message having a same number of control channel elements (CCEs);
ranking the corresponding allowable resource sets according to an index of a starting CCE for each corresponding allowable resource set or ranking the corresponding allowable resource sets randomly; andallocating resources for each ranked DCI message based, at least in part, on whether particular resources, which are to be allocated for a particular ranked DCI message, are collided, at least in part, with previously allocated resources for one or more other DCI messages. - View Dependent Claims (9, 10, 11, 12, 13)

14. An apparatus, comprising:
-
a memory element for storing data; and a processor for executing instructions associated with the data, wherein the executing causes the apparatus to perform operations, comprising; ranking a plurality of downlink control information (DCI) messages according to a first rank criterion; ranking a plurality of allowable resource sets for each ranked DCI message according to a second rank criterion, wherein ranking according to the second rank criterion further comprises at least one of; ranking, for each ranked DCI message, allowable resource sets for a particular ranked DCI message in ascending order according to a number of control channel elements (CCEs) required in each allowable resource set for the particular ranked DCI message; and for any corresponding allowable resource sets for the particular ranked DCI message having a same number of control channel elements (CCEs);
ranking the corresponding allowable resource sets according to an index of a starting CCE for each corresponding allowable resource set or ranking the corresponding allowable resource sets randomly; andallocating resources for each ranked DCI message based, at least in part, on whether particular resources, which are to be allocated for a particular ranked DCI message, are collided, at least in part, with previously allocated resources for one or more other DCI messages. - View Dependent Claims (15, 16, 17, 18, 19, 20)
