Abstract:
A UE in an eDRX cycle may miss an SI change notification because the UE's receiver may be powered down during the entire modification period prior to the SI change. An apparatus for wireless communication at a base station may transmit SI, change the SI during a period of eDRX by a UE, and transmit the changed SI. The apparatus ensures that a UE receives an SI change notification, even when performing eDRX, by transmitting at least one notification associated with the changed SI after the transmission of the changed SI and during a paging occasion for the UE. In another aspect, an apparatus for wireless communication at a UE enters into an eDRX cycle and receives, after an SI change, a notification associated with the SI change.
