Abstract:
A method of transmitting data through a downlink common transport channel in a wireless communication system is disclosed. The method comprises receiving measurement information transmitted from a user equipment at an upper network node, forwarding control information of the common transport channel, which is acquired from the measurement information, from the upper network node to a base station, and transmitting downlink data from the base station to the user equipment through the common transport channel in accordance with the control information.
Abstract:
According to one embodiment, a method of performing a re-establishment procedure in a mobile communication system includes: receiving at least one packet data convergence protocol (PDCP) control plane data unit; performing an integrity check on the at least one PDCP control plane data unit; identifying an integrity check failure with regard to the at least one PDCP control plane data unit; and performing a re-establishment procedure if the integrity check failure is identified to exist with regard to the at least one PDCP control plane data unit.
Abstract:
The present specification proposes a technique for controlling a deactivation timer of a cell. Specifically, the present specification proposes a method for controlling a deactivation timer of a cell in a mobile communication system. The method comprises the steps of: configuring a primary cell and at least one secondary cell on user equipment (UE); receiving, from the UE, an indicator related to a deactivation timer for one secondary cell from among one or more secondary cells; and disabling, on the UE, the deactivation timer of one secondary cell on the basis of the indicator.
Abstract:
According to one embodiment, a method for retransmitting a protocol data unit (PDU) in a mobile communication system includes: segmenting a first PDU to form one or more second PDUs if the first PDU does not fit within a PDU size indicated by a lower layer; and transmitting the one or more second PDUs to a receiving side. Segmenting the first PDU includes: mapping only a data field of the first PDU to a data field of the one or more second PDUs; and setting a header of each of the one or more second PDUs. The header of each of the one or more second PDUs includes a field indicating a sequence number of the first PDU.
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:
A method of reporting measurement results performed by a user equipment in a wireless communication system is provided. The method includes: measuring at least one cell; checking whether interference occurs during the measurement; and transmitting a measurement report to a network. If the interference does not occurs, the method further includes logging the measurement result in the measurement report.
Abstract:
A method of controlling uplink synchronization state at a user equipment in a mobile communication system is disclosed. The method of controlling an uplink synchronization state at a user equipment in a mobile communication system comprises receiving control information associated with controlling uplink synchronization state of the user equipment from a network, releasing uplink resources allocated from the network if the uplink synchronization state is shifted from a synchronization state to an asynchronous state based on the control information.
Abstract:
A method for measurement by a user equipment (UE) in a wireless communication system is provided. The method includes: receiving cell identity split information indicating a cell identity set reserved for a predetermined cell type from a network; determining whether to apply the cell identity split information in performing measurement; and measuring at least one cell. If the UE receives a logged measurement configuration including information regarding performing of logged minimization driving test (MDT), the measurement is performed without applying the cell identity split information. The UE does not receive the logged measurement configuration, the measurement is performed by applying the cell identity split information.
Abstract:
A method of allocating radio resources in a wireless communication system is disclosed. A method of allocating radio resources from a network of a wireless communication system in accordance with a plurality of scheduling modes comprises transmitting first scheduling information to a user equipment to allocate radio resources to the user equipment in accordance with a first scheduling mode, the first scheduling information including a first user equipment identifier, and transmitting second scheduling information to the user equipment to allocate radio resources to the user equipment in accordance with a second scheduling mode, the second scheduling information including a second user equipment identifier.
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.
