Abstract: A method and apparatus of reporting logged measurements in a wireless communication system is provided. A user equipment in a Radio Resource Control (RRC) connected mode receives Minimization of Drive Tests (MDT) configuration from a base station and starts a validity timer upon receiving the MDT configuration. The user equipment in an RRC idle mode logs measurements based on the MDT configuration to collect logged measurements while the validity timer is running. When the validity timer is expired, the user equipment discards the MDT configuration.

Abstract: There is provided a method for enabling a user equipment (UE) to transition between a non-discontinuous reception (Non-DRX) level and at least one discontinuous reception (DRX) level. The LIE in a DRX level wakes up periodically to monitor a scheduling channel. The method includes receiving a DRX indicator in a Non-DRX level with continuously monitoring the scheduling channel and transitioning from the Non-DRX level to a DRX level indicated by the DRX indicator. The UE can transition between multiple DRX levels by an explicit command/signaling.

Abstract: A method and system for processing buffer status reports (BSRs) such that when BSR triggering is performed, the size(s) of the necessary sub-header(s) are also to be considered together in addition to the BSR size. The steps of checking whether any padding region is available in a MAC PDU that was constructed, comparing the number of padding bits with the size of the BSR plus its sub-header, and if the number of padding bits is larger than the size of the BSR plus its sub-header, triggering BSR are performed. Doing so allows the sub-header(s) to be inserted or included into the MAC PDU or transport block (TB) or other type of data unit.
