1. A wireless transmit/receive unit (WTRU) comprising:
- a receiver configured to receive scheduling information, wherein the scheduling information is for receiving a first earthquake and tsunami warning system (ETWS)-system information block (ETWS-SIB) and a plurality of ETWS sub-SIBs of a second ETWS-SIB, wherein the plurality of ETWS sub-SIBs include segments of an ETWS message of the second ETWS-SIB;
the receiver further configured to receive as separate transmissions the first ETWS-SIB and the plurality of ETWS sub-SIBs using the scheduling information; and
a processor configured to process the first ETWS-SIB and the ETWS sub-SIBs to recover an ETWS message of the first ETWS-SIB and the ETWS message of the second ETWS-SIB to enable display of information associated with the ETWS message of the first ETWS-SIB and information associated with the ETWS message of the second ETWS-SIB, wherein the segments are combined to recover the ETWS message of the second ETWS-SIB.

Abstract
A method and apparatus for providing an ETWS message to a wireless transmit receive unit (WTRU). The WTRU is configured to receive a paging message indicating a change in system information, wherein in response to the paging message to receive a system information block (SIB) 1 to determine a schedule for reception of earthquake and tsunami warning system (ETWS) information in system information blocks (SIBs). The WTRU is further configured to receive the SIBs with the ETWS information and to separately receive segments of an ETWS message and to combine the segments to reproduce the ETWS message.

9. A base station comprising:
-
a transmitter configured to transmit scheduling information, wherein the scheduling information is for transmitting a first earthquake and tsunami warning system (ETWS)-system information block (ETWS-SIB) and a plurality of ETWS sub-SIBs of a second ETWS-SIB, wherein the plurality of ETWS sub-SIBs include segments of an ETWS message of the second ETWS-SIB; and the transmitter further configured to transmit the first ETWS-SIB and the plurality of ETWS sub-SIBs as separate transmissions based on the scheduling information to enable a wireless transmit/receive unit (WTRU) to process the first ETWS-SIB and the plurality of ETWS sub-SIBs to recover an ETWS message of the first ETWS-SIB and the ETWS message of the second ETWS-SIB and to enable display of information associated with the ETWS message of the first ETWS-SIB and information associated with the ETWS message of the second ETWS-SIB. - View Dependent Claims (10, 11, 12)
