Supporting random access and paging procedures for reduced capability WTRUs in an LTE system
First Claim
1. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
- receiving downlink control information (DCI), wherein the DCI comprises an indication of whether the DCI includes system information (SI) update information and whether the DCI includes scheduling information associated with a paging message;
on a condition that the indication indicates that the DCI includes SI update information;
receiving one or more updated systems information blocks (SIBs) based on the indication; and
operating in accordance with the one or more updated SIBs; and
on a condition that the indication indicates that the DCI includes scheduling information associated with a paging message;
receiving the paging message in a downlink channel based on the scheduling information.

Abstract
A wireless transmit/receive unit (WTRU) may transmit a preamble using a physical random access channel (PRACH) and determine a location of a random access response (RAR) based on a parameter of the PRACH. The location may include a subframe and/or a frequency resource on which the RAR is transmitted. The RAR may be received at the location. A device may receive a preamble using a PRACH associated with a coverage enhancement (CE) level and/or a CE mode of a WTRU. The device may determine a location of an RAR based on a parameter of the PRACH. The location may include a subframe and/or a frequency resource on which the RAR is to be transmitted. The device may determine a number of repetitions of the RAR to transmit based on the CE level or CE mode. The RAR may be transmitted at the location with the determined number of repetitions.

19. A base station comprising:
-
a transceiver; and a processor to execute instructions to; determine whether system information (SI) is to be updated for a wireless transmit/receive unit (WTRU) and whether a paging message is to be sent to the WTRU; based on a determination that SI is to be updated for the WTRU; indicate one or more systems information blocks (SIBs) that are to be updated in downlink control information (DCI); based on a determination that a paging message is to be sent to the WTRU; include scheduling information associated with the paging message in the DCI; and transmit the DCI to the WTRU, wherein the DCI comprises an indication of whether SI has been updated and whether the WTRU is to receive the paging message. - View Dependent Claims (20)
