Abstract
Official abstract text for this publication.
A user equipment (UE) that includes reception circuitry configured to receive system information from a cell is provided. The system information includes: one or more network identifiers, each of which identifying a public land mobile network (PLMN) or a Non-Public Networks (NPN) and identifying cell status information. The UE also includes processing circuitry configured to determine whether the cell status information indicates that the cell is barred, or to be treated as barred, for the UE. In a case that a Public Warning System (PWS) broadcast service is supported by the cell, the UE is allowed to camp on the cell for receiving one or more PWS messages, even if the cell status information indicates that the cell is barred, or to be treated as barred, for the UE.
First claim
Opening claim text (preview).
What is claimed is: 1 . A user equipment (UE), comprising: reception circuitry configured to receive system information from a cell, the system information comprising: one or more network identifiers, each of the one or more network identifiers identifying a public land mobile network (PLMN) or a Non-Public Networks (NPN); and cell status information; and processing circuitry configured to determine whether the cell status information indicates that the cell is barred, or to be treated as barred, for the UE, wherein a Public Warning System (PWS) broadcast service is supported by the cell in a case that the system information includes a PWS-Support information element (IE), and in a case that the PWS-Support IE is absent from the system information and all of the one or more network identifiers identify the NPN, the PWS broadcast service is not supported in the cell. 2 . The UE of claim 1 , wherein the PWS-Support IE is included in a system information block 1 (SIB1). 3 . The UE of claim 1 , wherein, while the UE is allowed to camp on the cell for receiving one or more PWS messages in the case that the PWS broadcast service is supported in the cell and the cell status information indicates that the cell is barred, or to be treated as barred, for the UE, the UE is not allowed to initiate a random access (RA) procedure on the cell. 4 . A method performed by a user equipment (UE), the method comprising: receiving system information from a cell, the system information comprising: one or more network identifiers, each of the one or more network identifiers identifying a public land mobile network (PLMN) or a Non-Public Network (NPN); and cell status information; and determining whether the cell status information indicates that the cell is barred, or to be treated as barred, for the UE, wherein a Public Warning System (PWS) broadcast service is supported by the cell in a case that the system information includes a PWS-Support information element (IE), and in a case that the PWS-Support IE is absent from the system information and all of the one or more network identifiers identify the NPN, the PWS broadcast service is not supported in the cell. 5 . A base station apparatus, comprising: transmission circuitry configured to transmit system information to a user equipment (UE), the system information comprising: one or more network identifiers, each of the one or more network identifiers identifying a public land mobile network (PLMN) or a Non-Public Network (NPN); and cell status information, wherein transmission of the system information causes the UE to determine whether the cell status information indicates that a cell is barred, or to be treated as barred, for the UE, a Public Warning System (PWS) broadcast service is supported by the cell in a case that the system information includes a PWS-Support information element (IE), and in a case that the PWS-Support IE is absent from the system information and all of the one or more network identifiers identify the NPN, the PWS broadcast service is not supported in the cell. 6 . The base station apparatus of claim 5 , wherein the PWS-Support IE is included in a system information block 1 (SIB1). 7 . The base station apparatus of claim 5 , wherein, while the UE is allowed to camp on the cell for receiving one or more PWS messages in the case that the PWS broadcast service is supported in the cell and the cell status information indicates that the cell is barred, or to be treated as barred, for the UE, the cell prevents the UE from initiating a random access (RA) procedure on the cell.
