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 UE 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 of processing control information in a mobile communication system is disclosed, by which an RRC connection setup can be quickly completed and by which control information can be processed without an unnecessary standby of a mobile terminal. The present invention includes the steps of receiving a plurality of protocol data units transmitted plural time from a transmitting side via one common logical channel by an RLC (radio link control) entity operating in a UM (unacknowledged mode) and having a receiving window and a timer, reordering a plurality of the received protocol data units using sequence numbers of a plurality of the received protocol data units, the receiving window and the timer, reassembling at least one service data unit by processing a plurality of the re-ordered protocol data units, and delivering the at least one service data unit.
Abstract:
A method including receiving, by a user equipment (UE), a block of first system information from a base station via the BCH, and receiving, by the UE, a first block of second system information from the base station via the DL_SCH. The first block of second system information is scheduled with a fixed time offset. The method further includes receiving, by the UE, a plurality of second blocks of second system information from the base station via the DL_SCH in accordance with scheduling information included in the first block of second system information. The first block of second system information includes the scheduling information, value tag information, and cell access related information. The cell access related information includes at least one of Public Land Mobile Network (PLMN) identity information, tracking area information, and cell barred information. A specific control channel indicates frequency and time information.
Abstract:
A method for transmitting radio resources in a mobile communication system is disclosed. The method includes receiving a random access channel (RACH) preamble from a plurality of UEs and transmitting response information associated with the received preambles over a common channel wherein the plurality UEs can access the common channel and receive corresponding information. If a HARQ scheme is used when a UE transmits data to the eNode-B using uplink radio resources allocated over the RACH, the eNode-B does not pre-allocate uplink radio resources required for re-transmission and performs allocation of radio resources for a first transmission of HARQ. If the re-transmission is required, the eNode-B allocates the radio resources required for the re-transmission with the NACK signal. If re-transmission is not required, the present invention can reduce an amount of wasted radio resources.
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:
A method of generating a data block to be transmitted from a protocol layer to a receiving side in a wireless communication system, the protocol layer having a header compression function, comprises generating at least one of a control packet which includes control information and a compressed packet generated by header compression for an upper layer data block, and generating a first lower layer data block which includes type indication information and the control packet, if the control packet is generated, the type indication information indicating a type of control information included in the generated control packet.
Abstract:
A method in which a user equipment processes data in a wireless mobile communication system is provided. The method includes the steps of receiving a first data block from an upper layer, transferring a second data block including the first data block to a lower layer at a particular protocol layer, discarding the first and second data blocks present in the particular protocol layer if a certain period of time has passed, and transferring information associated with the discard of the second data block to the lower layer.
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 and apparatus of allocating a resource for a plurality of logical channels is provided. A transmitter acquires a plurality of available resources for a plurality of component carriers, and allocates the plurality of available resources to the plurality of logical channels based on the priority of each of the plurality of logical channels. The resources are further allocated based on a first amount of data associated with each of the plurality of logical channels. Any remaining resources are allocated based on a second amount of data associated with each of the plurality of logical channels.
Abstract:
The present invention relates to a method for enabling a terminal to communicate with data by modifying an association relationship among component carriers in a mobile communication system supporting carrier aggregation and an apparatus therefor. The method in accordance with one embodiment of the present invention, comprises: receiving a message including identifier information for modifying an association relationship among at least one downlink component carrier and at least one uplink component carrier from a base station; receiving predetermined data through at least one downlink component carrier from the base station; and transmitting feedback data to the base station for data received through the uplink component carrier modified according to the identifier information.
