Abstract
A method, an apparatus, and a computer program product for wireless communication where a macro eNB or similar device may be configured to adjust an ABS configuration that is used for designating ABS subframes are provided to provide a VoLTE service to a UE. The ABS configuration may be adjusted by imposing one or more restrictions, such as alignment of the DRX OnDuration of a UE with some offset to the serving cell non-ABS subframes, and imposing restrictions on the ABS subframe settings at the macro eNB. The method or apparatus may initiate or terminate a wireless communication feature for a UE, and may adjust an ABS configuration based on the wireless communication feature, such that a maximum limit is set on a number of ABS subframes or a minimum limit is set on a number of non-ABS subframes based on the wireless communication feature.
