Abstract
A method and apparatus for receiving system information updates includes a wireless transmit receive unit (WTRU) receiving a system frame number. The WTRU also receives system information messages in a modification period. The modification period has a boundary determined by the system frame number. The WTRU receives system information change notification after a first modification change boundary and determines that the system information is valid until a second modification change boundary.
Claims14
A method for a wireless transmit receive unit (WTRU) to receive a system information update, the method comprising:
- receiving a system information update notification in a first modification period;
- receiving a system information update in a second modification period;
- obtaining a system frame number, SFN, and an integer value “n”;
- and
- determining, based on the SFN and the integer value, a system information modification period boundary that is between the first modification period and the second modification period.
A wireless transmit receive unit (WTRU) comprising:
- a receiver configured to receive first system information update notification in a first modification period and a second system information update notification in a second modification period;
- and
- a processor configured to obtain a system frame number (SFN) and an interger value “n”, and to determine, based on the system frame number and the integer value, a system information modification period boundary that is between the first modification period and the second modification period.
