Abstract

Disclosed is a method that decodes a broadcast channel to obtain first system information periodically broadcasted from a base station; applies at least one cell selection parameter indicated in the first system information to camp on a cell served by the base station and storing the first system information; accesses the camped cell based on at least one random access parameter indicated in the first system information; and determines whether at least one of a system information block of second system information available in the camped cell is provided based on at least one of the periodic broadcast and an on-demand basis. The on-demand basis to deliver the corresponding system information block of the second system information available in the camped cell is decided based on at least one of an indication and a flag included in the first system information for the system information block.

Claims10

Dependent claims

A method performed by a terminal in a wireless communication system, the method comprising:

acquiring a system information block (SIB) broadcasted from a first cell, the SIB includes a system configuration index associated with the SIB, a system information area identifier associated with the SIB and an indicator indicating area specific or cell specific for the SIB;
storing the acquired SIB;
upon performing a cell selection from the first cell to a second cell, acquiring an other SIB broadcasted from the second cell, the other SIB includes a system configuration index associated with the other SIB, a system information area identifier associated with the other SIB and an indicator indicating area specific or cell specific for the other SIB;
and
determining a validity of the stored SIB in the second cell by comparing the system configuration index associated with the other SIB, the system information area identifier associated with the other SIB and the indicator indicating area specific or cell specific for the other SIB with the system configuration index associated with the SIB, the system information area identifier associated with the SIB and the indicator indicating area specific or cell specific for the SIB.

2 more elements

A terminal in a wireless communication system, the terminal comprising:

a transceiver;
and
at least one processor configured to:
acquire via the transceiver a system information block (SIB) broadcasted from a first cell, the SIB includes a system configuration index associated with the SIB, a system information area identifier associated with the SIB and an indicator indicating area specific or cell specific for the SIB,
store the acquired SIB,
upon performing a cell selection from the first cell to a second cell, acquire via the transceiver an other SIB broadcasted from the second cell, the other SIB includes a system configuration index associated with the other SIB, a system information area identifier associated with the other SIB and an indicator indicating area specific or cell specific for the other SIB, and
determine a validity of the stored SIB in the second cell by comparing the system configuration index associated with the other SIB, the system information area identifier associated with the other SIB and the indicator indicating area specific or cell specific for the other SIB with the system configuration index associated with the SIB, the system information area identifier associated with the SIB and the indicator indicating area specific or cell specific for the SIB.
