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.
Claims14
A wireless transmit/receive unit (WTRU) comprising:
- a processor;
- and
- a transceiver,
- wherein the processor and the transceiver are configured to monitor for a physical downlink control channel (PDCCH) transmission scrambled using a system information (SI)-radio network temporary identifier (RNTI),
- wherein the processor and the transceiver are further configured to obtain, from downlink control information (DCI) on the PDCCH transmission scrambled using the SI-RNTI, scheduling information for system information (SI) and an indication of which SI is scheduled, wherein the SI includes at least a SIB-1 and at least one SIB other than the SIB-1, and
- wherein the processor and the transceiver are further configured to acquire at least one of the SIB-1 and the at least one SIB other than the SIB-1, from a downlink shared channel, using at least the scheduling information and the indication of which SI is scheduled obtained from the DCI on the PDCCH transmission scrambled using the SI-RNTI.

A method, implemented in a wireless transmit/receive unit, the method comprising:
- monitoring for a physical downlink control channel (PDCCH) transmission scrambled using a system information (SD-radio network temporary identifier (RNTI);
- obtaining, from downlink control information (DCI) on the PDCCH transmission scrambled using the SI-RNTI, scheduling information for system information (SI) and an indication of which SI is scheduled, wherein the SI includes at least a SIB-1 and at least one SIB other than the SIB-1;
- and
- acquiring at least one of the SIB-1 and the at least one SIB other than the SIB-1, from a downlink shared channel, using at least the scheduling information and the indication of which SI is scheduled obtained from the DCI on the PDCCH transmission scrambled using the SI-RNTI.
