Abstract
System information is transmitted over an air interface (32) between a node of a telecommunications network and a user equipment unit (30). The system information includes system information blocks which use extended system information block types, e.g., system information block type values which are outside a range of nominal system information block type values. The use of the extended system information block types is facilitated by embodiments of system information extension utility functions at the network node, by method of operating the network nodes, and by corresponding embodiments of system information processing functions provided at the user equipment unit (30).

8. A method of operating a node a of a telecommunications network which prepares network system information for transmission across an air interface to a user equipment unit, the system information including a system information block type which is included in protocol blocks, the protocol blocks being a system information block and a referencing block, the referencing block being one or both of a master information block and a scheduling block, the protocol blocks in which the system information is included having a system information block type field which includes a system information block type value which corresponds to the system information block type, the system information block comprising one or more segments, comprising the steps of:
-
including a first system information block type extension indicator in the system information block type field of the referencing block when the system information block type for a system information block referenced by the referencing block does not have a system information block type value in a nominal range of system information block type values;
including a first system information block type extension field in the referencing block;
including in the first system information block type extension field a system information block type extension value which indicates a system information block type for the system information block referenced by the referencing block; and
including a second system information block type extension indicator in the system information block type field of a segment of the system information block referenced by the referencing block. - View Dependent Claims (9, 10, 11, 12, 13, 14, 31, 32, 33, 34, 35)

15. A method for receiving network system information transmitted across an air interface from a network node at a user equipment unit, the system information including a system information block type which is included in protocol blocks, the protocol blocks being a system information block and a referencing block, the protocol blocks in which the system information is included having a system information block type field which includes a system information block type value which corresponds to the system information block type, the system information block comprising one or more segments, comprising the steps of:
-
recognizing a first system information block type extension indicator in the system information block type field of the referencing block when the system information block type for a system information block referenced by the referencing block does not have a system information block type value in a nominal range of system information block type values;
locating a first system information block type extension field in the referencing block;
obtaining from the first system information block type extension field a system information block type extension value which indicates a system information block type for the system information block referenced by the referencing block; and
recognizing a second system information block type extension indicator in the system information block type field of a segment of the system information block referenced by the referencing block. - View Dependent Claims (16, 39, 40, 41, 42, 43, 44, 45, 46)

47. A user equipment unit which receives network system information transmitted across an air interface from a network node, the system information including a system information block type which is included in protocol blocks, the protocol blocks being a system information block and a referencing block, the protocol blocks in which the system information is included having a system information block type field which includes a system information block type value which corresponds to the system information block type, the system information block including one or more segments, comprising:
-
means for recognizing a first system information block type extension indicator in the system information block type field of the referencing block when the system information block type for a system information block referenced by the referencing block does not have a system information block type value in a nominal range of system information block type values;
means for locating a first system information block type extension field in the referencing block;
means for obtaining from the first system information block type extension field a system information block type extension value which indicates a system information block type for the system information block referenced by the referencing block; and
means for recognizing a second system information block type extension indicator in the system information block type field of a segment of the system information block referenced by the referencing block.

51. A method for communicating network system information across an air interface between a network node and a user equipment unit, the system information including a system information block type which is included in protocol blocks, the protocol blocks being a system information block and a referencing block, the protocol blocks in which the system information is included having a system information block type field which includes a system information block type value which corresponds to the system information block type, the system information block comprising one or more segments, comprising the steps of:
-
including a first system information block type extension indicator in the system information block type field of the referencing block when the system information block type for a system information block referenced by the referencing block does not have a system information block type value in a nominal range of system information block type values;
including a first system information block type extension field in the referencing block;
including in the first system information block type extension field a system information block type extension value which indicates a system information block type for the system information block referenced by the referencing block;
including a second system information block type extension indicator in the system information block type field of a segment of the system information block referenced by the referencing block;
transmitting the referencing block and the system information block from the network node to the user equipment unit;
recognizing that said first system information block type extension indicator in the system information block type field of the received referencing block when the system information block type for a system information block referenced by the referencing block does not have a system information block type value in the nominal range of system information block type values;
locating said first system information block type extension field in the referencing block;
obtaining from the first system information block type extension field the system information block type extension value which indicates the system information block type for the system information block referenced by the referencing block; and
recognizing the second system information block type extension indicator in the system information block type field of a segment of the system information block referenced by the referencing block.
