Search space associated with physical downlink control channel based on channel quality indicators

An apparatus for wireless communication, the apparatus comprising:

• means for communicating with a first user equipment (UE) on a plurality of channels:
• means for receiving, from the first UE, a set of channel quality indicators (CQIs) associated with a set of channels that is a subset of the plurality of channels, the set of channels being based on channel qualities associated with the plurality of channels;
• means for determining, based on the received set of CQIs, a first set of control channel elements (CCEs) for a UE-specific search space specific to the first UE for receiving a physical downlink control channel (PDCCH) in at least one symbol allocated for control information;
• and
• means for sending, based on the determined first set of CCEs, downlink control information on the PDCCH in the UE-specific search space specific to the first UE.

An apparatus for wireless communication, the apparatus comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• communicate with a first user equipment (UE) on a plurality of channels;
• receive, from the first UE, a set of channel quality indicators (CQIs) associated with a set of channels that is a subset of the plurality of channels, the set of channels being based on channel qualities associated with the plurality of channels;
• determine, based on the received set of CQIs, a first set of control channel elements (CCEs) for a UE-specific search space specific to the first UE for receiving a physical downlink control channel (PDCCH) in at least one symbol allocated for control information;
• and
• send, based on the determined first set of CCEs, downlink control information on the PDCCH in the UE-specific search space specific to the first UE.

A non-transitory computer-readable medium storing computer-executable code for wireless communication by a base station, the code comprising instructions executable by a processor to:

• communicate with a first user equipment (UE) on a plurality of channels;
• receive, from the first UE, a set of channel quality indicators (CQIs) associated with a set of channels that is a subset of the plurality of channels, the set of channels being based on channel qualities associated with the plurality of channels;
• determine, based on the received set of CQIs, a first set of control channel elements (CCEs) for a UE-specific search space specific to the first UE for receiving a physical downlink control channel (PDCCH) in at least one symbol allocated for control information;
• and
• send, based on the determined first set of CCEs, downlink control information on PDCCH ire the UE-specific search space specific to the first UE.
