Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. In an aspect, the apparatus may receive a set of configurations for an EPDCCH that are tied to a set of configurations received for a PDSCH. The apparatus may then receive and process the EPDCCH based on at least one configuration from the set of configurations for the EPDCCH. In another 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.
