Abstract
Various mechanisms for paging link-budget-limited (LBL) devices are disclosed, including: (1) transmitting paging message with non-conventional paging identifier; (2) transmitting paging message(s) with increased power; (3) repeating transmission of paging message to support combining at receiver. Various mechanisms for UE device to signal LBL status are disclosed, including, transmitting status flag or special value of DRX cycle to network node as part of tracking area update and/or attach request. The network node informs a base station of the device's LBL status as part of a paging message. (The network node may, e.g., assign an S-RNTI to the LBL device from a reserved subset of S-RNTI space.) The base station invokes a paging enhancement mechanism when paging an LBL device. Alternatively, the base station may page UE devices without knowledge of LBL status, e.g., by counting paging attempts for a given UE, and boosting power after the Npaging attempt.
