摘要:
A method and apparatus of managing uplink time alignment in a wireless communication system is provided. A user equipment starts a time alignment timer which is used to control how long the user equipment is considered uplink time aligned and receives an expiry request message from a base station while the time alignment timer is running. Upon receiving the expiry request, the user equipment expires the time alignment timer and releasing uplink resources.

The present invention discloses a method for a serving network node to process a signal in a wireless communication system. In more detail, the method comprises the steps of: forming a communication link with a mobile device; receiving a message including network node list information that the mobile device can access from an external network node or from the mobile device; and transceiving a signal with the mobile device. Here, the mobile device is a relay node, and the external network node is an operation and maintenance (OAM) server or mobility management entity (MME).

Provided is a method for performing random access of a terminal in a wireless communication system. The method receives information about at least one first sub-frame from a base station, selects at least one second sub-frame from at least one first sub-frame, and transmits a random access preamble in a randomly selected sub-frame from at least one second sub-frame if the terminal is a specific type. If the terminal is not a specific type, the random access preamble is transmitted from the randomly selected sub-frame from at least one first sub-frame.

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.

The present invention provides an apparatus and method of reporting logged measurements in a wireless communication system. User equipment receives an MDT (Minimization of Drive Tests) configuration from a base station, and logs a measurement on the basis of the MDT configuration in order to collect logged measurements. The user equipment determines whether the logged measurement needs to be reported. If it is determined that the logged measurement needs to be reported, the user equipment transmits to the base station a report indicator indicating the need for reporting of the logged measurement.

A method for performing a logged measurement in wireless communication system is provided. The method includes receiving measurement configuration from a network, logging MDT (Minimization of Driving Tests) measurement, detecting whether a condition for state transition has occurred, performing state transition when the condition for state transition has occurred, and logging state transition information related to said state transition.

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 communication based on mobility evaluation in a wireless communication system is provided. The method includes: receiving evaluation basis information from a network, the evaluation basis information basis information comprising an offset value for mobility evaluation and a domain condition; determining whether the domain condition is satisfied; performing the mobility evaluation for at least one neighbor cell based on the offset value, if the domain condition is satisfied; and selecting a cell among the at least one neighbor cell as a mobility target cell, if a result of the mobility evaluation satisfies a predetermined criterion.
摘要:
A method and apparatus of reporting a power headroom in a wireless communication system are provided. A user equipment receives an uplink resource allocation for a first serving cell and determines whether a power headroom report is triggered. If the power headroom report is triggered, the user equipment determines a first power headroom for the first serving cell and a second power headroom for a second serving cell based on the uplink resource allocation.
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.
