Common control channel

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• receive common downlink control information (DCI) included in a physical downlink control channel (PDCCH) candidate, wherein the PDCCH candidate has a first size associated with a first aggregation level, wherein the common DCI is detectable at the first aggregation level by decoding the PDCCH candidate and detectable at a second aggregation level, smaller than the first aggregation level, by decoding a part of the PDCCH candidate, and wherein the part of the PDCCH candidate has a second size associated with the second aggregation level;
• and
• communicate based at least in part on the common DCI.

A base station for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• map common downlink control information (DCI) to a physical downlink control channel (PDCCH) associated with a PDCCH candidate, wherein the PDCCH candidate has a first size associated with a first aggregation level, wherein the common DCI is detectable at the first aggregation level by decoding the PDCCH candidate and detectable at a second aggregation level, smaller than the first aggregation level, by decoding a part of the PDCCH candidate, and wherein the part of the PDCCH candidate has a second size associated with the second aggregation level;
• and
• transmit the common DCI.
