Patent Images
1. A method of paging user equipments (UEs) on a shared communication medium, comprising:
- obtaining a set of paging messages for transmission to a paging group that includes a set of UEs associated with different coverage levels;
transmitting a common enhanced Physical Downlink Control Channel (ePDCCH) that starts a Paging Occurrence Window (POW) with a duration that is extended from a legacy POW used by one or more legacy UEs;
transmitting, after the transmission of the common ePDCCH, a paging ePDCCH; and
repetitively transmitting the set of paging messages over a plurality of PDSCH subframes in accordance with the paging ePDCCH.

Abstract
In an embodiment, an apparatus (e.g., eNB) pages UEs on a shared communication. The apparatus obtains paging message(s) for transmission to UEs with different coverage levels. The apparatus transmits an extended common ePDCCH, followed by a paging ePDCCH, followed by repetitive transmissions of the paging message(s) over a plurality of PDSCH subframes. In a further embodiment, the apparatus obtains first and second sets of paging messages for transmission to different paging groups. The apparatus establishes non-overlapping POWs for the first and second paging groups to avoid a paging ePDCCH collision.
