Search space set hashing under channel estimation capability

An apparatus for wireless communication, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify a candidate set of decoding candidates to which control information is configured to be mapped, each decoding candidate comprising one or more control channel elements (CCEs);
• select, from the candidate set of decoding candidates, an actual set of decoding candidates on which the UE is configured to decode the control information, selection being based on an evaluation of decoding candidates, the instructions executable by the processor to cause the apparatus to select the actual set of decoding candidates including instructions executable by the processor to:
• identify a decoding candidate of the candidate set to be evaluated;
• identify a number of CCEs in the decoding candidate being evaluated;
• determine an evaluation number of CCEs by adding the number of CCEs in the decoding candidate being evaluated to a number of CCEs already included within the actual set;
• and
• determine whether to add the decoding candidate being evaluated to the actual set of decoding candidates based at least in part on the evaluation number of CCEs and a threshold the comparison;
• and
• receive the control information within a search space comprising the actual set of decoding candidates, wherein the control information is decoded based at least in part on the actual set of decoding candidates.

An apparatus for wireless communication at a user equipment (UE), comprising:

• means for identifying a candidate set of decoding candidates to which control information is configured to be mapped, each decoding candidate comprising one or more control channel elements (CCEs);
• means for selecting, from the candidate set of decoding candidates, an actual set of decoding candidates on which the UE is configured to decode the control information, the means for selecting including an evaluation of decoding candidates through use of:
• means for identifying a decoding candidate of the candidate set to be evaluated;
• means for identifying a number of CCEs in the decoding candidate being evaluated;
• means for determining an evaluation number of CCEs by adding the number of CCEs in the decoding candidate being evaluated to a number of CCEs already included within the actual set;
• and
• means for determining whether to add the decoding candidate being evaluated to the actual set of decoding candidates based at least in part on the evaluation number of CCEs and a threshold;
• and
• means for receiving the control information within a search space comprising the actual set of decoding candidates, wherein the control information is decoded based at least in part on the actual set of decoding candidates.

• select, from the candidate set of decoding candidates, an actual set of decoding candidates on which the UE is configured to decode the control information, selection being based on an evaluation of decoding candidates, the instructions executable by the processor to select the actual set of decoding candidates including instructions executable by the processor to:
• identify a decoding candidate of the candidate set to be evaluated;
• identify a number of CCEs in the decoding candidate being evaluated;
• determine an evaluation number of CCEs by adding the number of CCEs in the decoding candidate being evaluated to a number of CCEs already included within the actual set;
• and
