Abstract
Methods and apparatus are provided for paging enhancement for LC-MTC devices. In one novel aspect, a new paging message is used. In one embodiment, a new system information (M-SI)-paging is provided either carrying a bitmap or being generated from specific M-P1-RNTI sequences to indicate the modified SI messages. In another embodiment, a new RRC-paging is used through a UE-specific message, a multicast message, or a broadcast message to inform a UE to establish a RRC connection. The new paging message is either a sequence or an encoded data packet transmitted without control information, or scheduled by M-PDCCH. In another novel aspect, the new paging message is transmitted within one or more cells by a broadcast mechanism to achieve a maximal CE level the one or more cells support, or a multi-cast mechanism to support a specified CE level range, or a unicast mechanism to support a CE level.
