Monitoring for a combination downlink control information (DCI) for scheduling transmissions in multiple cells

A method for wireless communications by a base station, comprising:

• determining a blind decode (BD) limit and a control channel element (CCE) limit based on a scaling factor less than one, wherein the scaling factor comprises a value that is reported by a user equipment (UE) to a cell as a UE capability;
• determining physical downlink control channel (PDCCH) parameters based on the BD limit and the CCE limit for a user equipment (UE) to monitor a combination downlink control information (DCI) that schedules at least one of data or reference signal (RS) transmissions in multiple cells;
• receiving, from the UE, a supported physical downlink control channel (PDCCH) blind detection capability based on one or more conditions being satisfied, wherein the one or more conditions are satisfied when a sum of a first number of cells with which the UE may be configured and a second number of cells with which the UE may be configured scaled by the scaling factor exceeds a threshold value, wherein the first number represents a number of cells not among the multiple cells configured by the combination DCI and the second number represents a number of cells among the multiple cells configured by the combination DCI;
• and
• transmitting, to the UE, the combination DCI based on the determined PDCCH parameters.

An apparatus for wireless communications by a user equipment (UE), comprising:

• a memory;
• and
• a processor configured to:

• and
• monitor for the combination DCI based on the determined PDCCH parameters.
