摘要:
A method and apparatus for monitoring a downlink control channel in a wireless communication system is provided. A wireless device receives a discontinuous reception (DRX) command from a base station. The DRX command indicates an activation of at least one DRX pattern from a plurality of DRX patterns. Each of the plurality of DRX patterns includes an on-duration which specifies at least one subframes to monitor a downlink control channel within a DRX cycle. The wireless device monitors the downlink control channel in at least one subframe which belongs to on-duration of the at least one activated DRX pattern.

A method and apparatus of processing a failure of a component carrier (CC) in a multiple carrier system is provided. A user equipment detects a failed CC in which a failure occurs among a plurality of CCs and determines whether to declare a radio link failure based on the failed CC. If it is not the radio link failure, the user equipment reports information on the failed CC to a base station.
摘要:
A method for performing random access in a wireless communication system is provided. The method includes transmitting a preamble for random access in uplink, receiving a random access response message including back-off information as a response to the preamble, and performing back-off using the back-off information when the random access has failed.

Provided are a transmission power reporting method and apparatus. A terminal determines a configured maximum transmission power based on a maximum power reduction (MPR) and transmission power configured by a base station and determines whether reporting of the configured maximum transmission power is triggered. If reporting of the configured maximum transmission power is triggered, the terminal transmits a reporting message including the configured maximum transmission power to the base station.
摘要:
A method for prompt re-direction of uplink access of a specific user equipment is disclosed. For initial random access to a network, if a user equipment transmits a preamble, which includes information related to random access, to a network node, the network node sends grant/rejection information of the preamble and re-direction information as a response message to the preamble. In comparison with the related art which controls a rush of an access request of the user equipment through a second response message from the network node, since the rush of an access request is controlled by a first response message in the present invention, it is possible to promptly deal with abnormal communication status, thereby improving communication efficiency.

Provided are a method and an apparatus for coordinating inter-cell interference. A user equipment receives from a serving cell information on a downlink timing offset between an interfering cell and an interfered cell and a limited resource measurement, and applies the downlink timing offset to perform measurement using a radio resource indicated for the limited resource measurement, thereby allowing the user equipment to be provided services through the radio resource which substantially mitigates interference, and enhancing connectivity with a network.
摘要:
Method, system and devices for managing carrier aggregation in a radiocommunication system. According to the method, the user equipment (3) carries out the steps of: receiving (7;12) a list of multiple carriers in a determined order; and selecting (9;14) one carrier from the list of multiple carriers as a serving carrier, based on a position of said carrier in the list of multiple carriers.
摘要:
A method of a Mobile Station (MS) configuring radio connection in a multiple component carrier system is provided. The method includes receiving distribution information from a Base Station (BS) through a first Component Carrier (CC), selecting a second CC for radio connection to the BS on a basis of the distribution information, and performing the radio connection through the second CC.
摘要:
A method for avoiding collision among transmissions from user equipment in a mobile network is provided. The method includes transmitting a preamble to a base station via a random access channel (RACH) and transmitting a response signal including an identifier of the user equipment to the user equipment in response to the RACH. It is possible to transmit/receive reliable data while reducing collision among transmissions from user equipment by efficiently using the identifier of the user equipment when the user equipment uses the RACH.
摘要:
The present invention relates to a method and apparatus for performing a logged measurement in a wireless communication system. A terminal receives a measurement configuration and a terminal selection parameter from a base station. The terminal determines whether or not to apply the measurement configuration based on the terminal selection parameter. If the measurement configuration is determined to be applied, the terminal logs a measurement based on the measurement configuration.
