Abstract: A method of moving a receiving window in a wireless mobile communication system, wherein the AM RLC of the transmitting side sends information of the last discarded SDU regardless of continuity of the discarded SDUs. The AM RLC of the receiving side checks whether all SDUs from the start point of the receiving window up to the last discarded SDU are successfully received, delivers the SDUs that are successfully received to an upper layer, and discard only those SDUs that are not successfully received.

Abstract: A method of discarding logged measurements in a wireless communication system is provided. A user equipment in a Radio Resource Control (RRC) connected mode receives a 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 and starts a conservation timer. When the conservation timer is expired, the logged measurements are discarded.

Abstract: The present specification proposes a scheme for controlling a deactivation timer of a cell. More specifically, the present specification proposes a method of controlling a deactivation timer of a cell in a mobile communication system. The method includes: configuring, at a user equipment (UE), a first deactivation timer of a first cell and a second deactivation timer of a second cell, wherein the first cell and the second cell belong to a same timing advance group (TAG); if the first deactivation timer of first cell expires, checking, at the UE, whether uplink timing of the same TAG is required to be maintained; and if the uplink timing of the same TAG is required to be maintained, restarting, at the UE, the first deactivation timer of the first cell.

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.
