Abstract
A system information indication method and apparatus and a communication system. In the embodiments of this disclosure, by indicating a correspondence between an area related ID or a system information related index and system information, and/or notifying information on a change of the area related ID or system information related index, a case may be avoided where a UE needs still to obtain system information from a network side when system information of a current cell is stored, thereby efficiently lowering power consumption of the UE in acquiring the system information.
Claims9
A user equipment (UE) comprising:
- a memory configured to store a system information block(s);
- a receiver configured to receive information on an area related identity (ID) corresponding to a system information block(s) mapping information field (SIB-Mappinginfo field), the area related ID corresponding to a number of a system information block(s);
- and
- processor circuitry configured to:
- control to check whether the stored system information block(s) is valid according to the information, and
- configure the SIB-Mappinginfo field for the are related identity (ID) in a message broadcast by a network side,
- wherein a bit included in the SIB-Mappinginfo field corresponds to a system information block, and the bit indicates that the system information block is associated with the area related ID.
A network device, comprising:
- a memory;
- processor circuitry coupled to the memory and is configured to:
- transmit information on an area related identity (ID) corresponding to a system information block(s) mapping information field (SIB-Mappinginfo field), the area related ID corresponding to a number of a system information block(s),
- cause a user equipment (UE) to check whether a system information block(s) to which the UE is stored is valid according to the information by transmitting the information, and
- configure the SIF-Mappinginfo field for the area related identity (ID) in a broadcast message,
- wherein a bit included in the SIB-Mappinginfo field corresponds to a system information block, and the bit indicates that the system information block is associated with the area related ID.
A wireless communication system comprising:
- a network device configured to:
- transmit information on an area related identity (ID) corresponding to a system information block(s) mapping information field (SIB-Mappinginfo field), the area related ID corresponding to a number of a system information block(s), and
- configured the SIB-Mappinginfo field for the area related identity (ID) in a broadcast message, wherein a bit included in the SIB-Mappinginfo field corresponds to a system information block, and the bit indicates that the system information block is associated with the area related ID;
- and
- a receiver configured to:
- receive the information from the network device, and
- control to check whether the stored system information block(s) is valid according to the information.
