First Claim
Patent Images
1. A method, implemented in a wireless transmit/receive unit (WTRU), the method comprising:
- receiving a signal derived from a paging radio network temporary identifier (P-RNTI), wherein the signal includes downlink control information (DCI), the signal is without downlink (DL) grant information for an associated paging message, and the DCI includes at least one of a single bit indication of system information modification, an earthquake tsunami warning system (ETWS) indication, or a commercial mobile alert service (CMAS) indication; and
on a condition that the at least one single bit indication indicates that a system information block (SIB) has changed or will change, acquiring or re-acquiring the SIB.

Abstract
A method and apparatus are described. A method includes determining whether the apparatus is in a coverage enhancement (CE) mode or a non-CE mode. The method further includes receiving a CE-system information block (CE-SIB) on a physical downlink shared channel (PDSCH) based on at least one of a known location or at least one known parameter for the CE-SIB, on a condition that the WTRU is determined to be in the CE mode.

9. A wireless transmit/receive unit (WTRU) comprising:
-
a transceiver; and a processor, wherein the transceiver and the processor are configured to receive a signal derived from a paging radio network temporary identifier (P-RNTI), wherein the signal includes downlink control information (DCI), the signal is without downlink (DL) grant information for an associated paging message, and the DCI includes at least one of a single bit indication of system information modification, an earthquake tsunami warning system (ETWS), or a commercial mobile alert service (CMAS), and wherein the transceiver and the processor are further configured to acquire or re-acquire a system information block (SIB) on a condition that the at least one single bit indication indicates that the SIB has changed or will change. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
