5. A base station apparatus comprising:
processor circuitry configured to generate a value tag associated with a second type system information block, the second type system information block being associated with a first value tag, the second type system information block being area specific or cell specific, an area specific second type system information block being valid within an area, a cell specific second type system information block being valid within a cell; and
transmitting circuitry configured to transmit, to a user equipment (UE), a first type system information block and the second type system information block, the first type system information block comprising the value tag and an indication, the indication indicating whether the second type system information block is provided on-demand,
wherein;
the value tag associated with the second type system information blocks and whether the second type system information blocks is area specific or cell specific are used by the UE to initiate a reception procedure to obtain the second type system information block;
the reception procedure comprises transmission of a request message for the second type information block based on the indication; and
the first type system information block is used for transmitting minimum system information, the minimum system information comprising, at least, information required for an initial access.
6. The base station apparatus according to claim 5 , wherein the second type system information block comprises other system information not included in the minimum system information.
7. The base station apparatus according to claim 6 , further comprising receiving circuitry configured to receive the request message from the UE.
8. A communication method of a user equipment (UE) comprising:
storing a second type system information block, the second type system information block being associated with a first value tag, the second type system information block being area specific or cell specific, an area specific second type system information block being valid within an area, a cell specific second type system information block being valid within a cell;
receiving, from a base station apparatus, a first type system information block comprising an indication and a second value tag associated with the second type system information block, the indication indicating whether the second type system information block is provided on-demand; and
initiating a reception procedure to obtain the second type system information block, based on whether the stored second type system information block is area specific or cell specific, the first value tag and the second value tag,
wherein:
the reception procedure comprises transmission of a request message for the second type information block based on the indication; and
the first type system information block is used for receiving minimum system information, the minimum system information comprising, at least, information required for an initial access.
9. The communication method according to claim 8 , wherein for the stored second type system information block, validity is determined based on the first value tag and the second value tag.
10. The communication method according to claim 9 , wherein the second type system information block comprises other system information not included in the minimum system information.
11. The communication method according to claim 10 , further comprising transmitting the request message to the base station apparatus.
12. A communication method of a base station apparatus comprising:
generating a value tag associated with a second type system information block, the second type system information block being area specific or cell specific, an area specific second type system information block being valid within an area, a cell specific second tpe system information block being valid within a cell; and
transmitting, to a user equipment (UE), a first type system information block and the second type system information block, the first type system information block comprising the value tag and an indication, the indication indicating whether the second type system information is provided on-demand,
wherein:
the value tag associated with the second type system information block and whether the second type system information block is area specific or cell specific are used by the UE to initiate a reception procedure to obtain the second type system information block;
the reception procedure comprises transmission of a request message for the second type information block based on the indication; and
the first type system information block is used for transmitting minimum system information, the minimum system information comprising, at least, information required for an initial access.
