Abstract:
PROBLEM TO BE SOLVED: To provide a method for performing carrier management in user equipment (UE) of a wireless communication system. SOLUTION: The method includes the stages of disposing a plurality of carriers, and activating or deactivating one carrier group the plurality of carriers, according to medium access control (MAC) signaling.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and communication apparatus for improving a reconfiguration procedure for Scheduling Request (SR) to be used in a user equipment (UE) of a wireless communication system, so as to appropriately reconfigure a Scheduling Request (SR) procedure parameter. SOLUTION: The method includes steps of: receiving an upper layer protocol request for reconfiguring an SR procedure parameter of the UE; and applying a new configuration value provided by the upper layer protocol request to the SR procedure parameter when an SR is triggered by the UE and there is no other SR pending in the UE.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a related device which improve DRX (discontinuous receiving) functionality in a wireless communication system. SOLUTION: The method includes a stage of going into the DRX cycle, a stage of producing a first result by carrying out a first equation based on the number of a system frame, the number of a sub frame and a variable of DRX cycle, a stage of producing a second result by carrying out a second equation based on the variable of DRX starting offset variable as well as the variable of the DRX cycle, and a stage of monitoring PDCCH by starting an on-duration timer when the first result coincides with the second result.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a communication apparatus for determining a dedicate searching space, named DSS in a physical downlink control channel, named PDCCH for reducing a load of blind decoding. SOLUTION: The method includes a step of indicating a UE to monitor a SPS C-RNTI (semi-persistent scheduling cell radio network temporary identifier) in the PDCCH for receiving a SPS (semi-persistent scheduling) grant, and a step of determining the DSS for monitoring the SPS C-RNTI based on a C-RNTI (cell radio network temporary identifier) of the UE (user terminal).

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a communication apparatus for handling permanent resources in UE (user equipment) of a wireless communication system so as to prevent disturbance to uplink transmission by another UE by performing uplink transmission in an asynchronous state. SOLUTION: The method includes stages of obtaining permanent resources, allocated to the UE and of releasing the permanent resources, when a time alignment timer in the UE expires.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a communication apparatus for improving HARQ (hybrid automatic repeat request) process uplink transmission so as to avoid disturbance to the uplink transmission by another UE (user equipment). SOLUTION: The method includes a stage wherein the HARQ entity of UE instructs a HARQ process to perform transmission or retransmission of a corresponding packet which corresponds to an uplink grant allocated to the UE, and a stage of flushing all HARQ buffers, corresponding to uplink transmission in the HARQ entity, when a time alignment timer of the UE expires.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for improving an RRC (Radio Resource Control) Connection procedure in a UE (user equipment) of a wireless communication system, and also to provide a related communication apparatus. SOLUTION: The method includes steps of: performing an RRC Connection procedure; and resetting or re-establishing a lower layer protocol entity for SRBs (Signalling Radio Bearers) when a cell re-selection occurs.
