Wireless telecommunications methods and apparatus using system information value tag
Method and apparatus use a value tag in conjunction with transmission and/or processing of system information in a wireless communication network, especially in conjunction with second type system information or non-essentially type system information.
1. A user equipment (UE) comprising:
receiving circuitry configured to receive, from a base station apparatus, a first type system information block and one or more second type system information blocks, the first type system information block comprising one or more value tags, each of the one or more value tags being associated with one corresponding block of the one or more second type system information blocks, each of the one or more second type system information blocks 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
processing circuitry configured to store the one or more second type system information blocks, wherein
the processing circuitry is configured to determine validity for each of the stored one or more second type system information blocks, based on the associated value tag and whether each of the stored one or more second type system information blocks is area specific or cell specific, 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.
2. The UE according to claim 1 , wherein for the each of the stored one or more second type system information blocks, the validity is determined based on the associated value tag.
3. The UE according to claim 2 , wherein the one or more second type system information blocks comprise other system information not included in the minimum system information.
4. The UE according to claim 3 , further comprising transmitting circuitry configured to transmit, to the base station apparatus, information used for requesting at least one of the one or more second type system information blocks.
5. A base station apparatus comprising:
transmitting circuitry configured to transmit, to a user equipment (UE), a first type system information block and one or more second type system information blocks, the first type system information block comprising one or more value tags, each of the one or more value tags being associated with one corresponding block of the one or more second type system information blocks, each of the one or more 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, wherein
the one or more second type system information blocks are to be stored in the UE,
validity for each of the stored one or more second type system information blocks is determined based on the associated value tag and whether each of the stored one or more second type system information blocks is area specific or cell specific, 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 according to claim 5 , wherein for the each of the stored one or more second type system information blocks, the validity is determined based on the associated value tag.
7. The base station apparatus according to claim 6 , wherein the one or more second type system information blocks comprise other system information not included in the minimum system information.
8. The base station apparatus according to claim 7 , further comprising receiving circuitry configured to receive, from the UE, information used for requesting at least one of the one or more second type system information blocks.
9. A communication method of a user equipment (UE) comprising:
receiving, from a base station apparatus, a first type system information block and one or more second type system information blocks the first type system information block comprising one or more value tags, each of the one or more value tags being associated with one corresponding block of the one or more second type system information blocks, each of the one or more 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,
storing the one or more second type system information blocks, and
determining validity for each of the stored one or more second types of system information, based on the associated value tag and whether each of the stored one or more second type system information blocks is area specific or cell specific, and wherein
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.
10. The communication method according to claim 9 , wherein for the each of the stored one or more second type system information blocks, the validity is determined based on the associated value tag.
11. The communication method according to claim 10 , wherein the one or more second type system information blocks comprise other system information not included in the minimum system information.
12. The communication method according to claim 11 , further comprising transmitting, to the base station apparatus, information used for requesting at least one of the one or more second type system information blocks.
13. A communication method of a base station apparatus comprising:
transmitting, to a user equipment (UE), a first type system information block and one or more second type system information blocks, the first type system information block comprising one or more value tags, each of the one or more value tags being associated with one corresponding block of the one or more second type system information blocks, each of the one or more 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, wherein
the one or more second types of system information are to be stored in the UE,
validity for each of the stored one or more second type system information blocks is determined based on the associated value tag and whether each of the stored one or more second type system information blocks is area specific or cell specific, 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.
14. The communication method according to claim 13 , wherein for the each of the stored one or more second type system information blocks, the validity is determined based on the associated value tag.
15. The communication method according to claim 14 , wherein the one or more second type system information blocks comprise other system information not included in the minimum system information.
16. The communication method according to claim 15 , further comprising receiving, from the UE, information used for requesting at least one of the one or more second types of system information.
