Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. In an aspect, the apparatus may configure at least a first resource set and a second resource set for a control channel. The first and second resource sets may be configured with a common reference signal configuration. The apparatus also configures first rate-matching parameters for the first resource set and second rate-matching parameters for the second resource set. Then, the apparatus transmits the first rate-matching parameters and the second rate-matching parameters and transmits the control channel using the first resource set and the second resource set.
