`ABSTRACT
`( 57 )
`A method , an apparatus , and a computer program product
`for wireless communication are provided . In an aspect , the
`apparatus may determine at least a first and second resource
`set configured for a control channel and may determine a
`common set of aggregation levels for the first and second
`resource sets . The apparatus may further determine first
`rate - matching parameters for the first resource set and
`second rate - matching parameters for the second resource
`set , and may process the control channel using the common
`set of aggregation levels and the first and second rate
`matching parameters .
