User devices, base stations, and methods for wireless communication

Abstract

The invention relates to wireless communication, more specifically to user equipment, base stations and methods for wireless communication. In some respects the user equipment (UE) can be identified, For orthogonal frequency division (OEl)M symbols comprising one or more cell-specific reference signal (CRS) elements and one or more narrowband physical downlink shared channel (NPDSCH) elements, the energy per resource element (EPRE) NPDSCH, In this invention, EPRE NPDSCH provides OFDM symbols based at least in part on the EPRE differential between the EPRL narrowband reference signal (NRS) and the EPRE CRS. The UE can demodulate OFDM symbols based at least in part on the EPRE NPDSCH. The invention also addresses many other aspects.
