Abstract:
A method and apparatus for supporting a closed subscriber group (CSG) service is provided. A user equipment determines whether a neighbor cell is a CSG member cell for which a CSG whitelist includes a CSG identity of the neighbor cell and PLMN identities of the neighbor cell. The user equipment sends a CSG membership indicator indicating whether the neighbor cell is the CSG member cell.
Abstract:
A method and apparatus for supporting a closed subscriber group (CSG) service is provided. The apparatus includes a memory to store CSG subscription information and a processor operatively coupled to the RF unit and memory to implement a radio interface protocol. The processor accesses a base station (BS), transmits the CSG subscription information to the BS, receives an access mode from the BS where the access mode is determined based on the CSG subscription information, and negotiates with the BS with regard to a CSG service if the access mode supports a CSG to which the apparatus belongs.
Abstract:
Provided are a method and device in which a terminal manages component carriers in a wireless communication system. The terminal receives activation pattern data indicating activation or inactivation of at least one serving cell from a base station, and activates or inactivates the at least one component carrier in accordance with the activation pattern data.
Abstract:
A method is described for operating a device in a wireless communication system. The device communicates with a base station using a subframe for the device only; detects, by the device, a problem with a connection between the device and the base station. The device starts a timer upon detecting the problem with the connection between the device and the base station. The device releases a restriction of using the subframe for the device only, if the timer expires. The problem with the connection between the device and the base station is associated with a radio link failure. The detection of a problem with the connection between the device and the base station comprises detecting consecutive out-of-sync indications.
Abstract:
A method and apparatus of reporting measurement results in a wireless communication system is provided. A user equipment receives a measurement configuration which configures a plurality of serving cells as measurement objects and performs measurements for the plurality of serving cells based on the measurement configuration to determine measurement results for the plurality of serving cells. The user equipment reports the measurement results for the plurality of serving cells.
Abstract:
A method for operating a relay node in a wireless communication system. The method includes communicating, by the relay node, with a base station using a specific subframe for the relay node only; detecting, by the relay node, a problem with a connection between the relay node and the base station; starting, by the relay node, a timer upon detecting the problem with the connection between the relay node and the base station; and releasing, by the relay node, a restriction of using the specific subframe for the relay node only, if the started timer expires. The problem with the connection between the relay node and the base station is associated with a radio link failure.
Abstract:
Disclosed is a wireless communication system and terminal for providing a wireless communication service, and more particularly, a method of effectively perform an operation of MDT (Minimization Driving Test) for a specific area or a specific cell in an Evolved Universal Mobile Telecommunications System (E-UMTS) evolved from a UMTS, Long Term Evolution (LTE) System or LTE-Advanced (LTE-A) system.
Abstract:
The present invention provides a method of receiving a timing advance command by a user equipment in a wireless communication system. A terminal receives information on a time advance group from a base station, and also receives the tuning advance command corresponding to the time advance group from the base station.
Abstract:
A method for random access to a base station by a user equipment (UE) in a mobile communication system using carrier aggregation in which communication is conducted over a plurality of component carriers, and a terminal for the method are disclosed. When the UE performs a contention-based random access procedure in the mobile communication system to which CA technology is applied, the UE considers an uplink grant signal as a contention resolution message when receiving the uplink grant signal from a eNB only when the uplink grant signal is received through a downlink CC corresponding to an uplink CC used to transmit a random access preamble or a third message, to thereby prevent contention resolution from being erroneously ended.
Abstract:
A method is provided for performing, by a user equipment (UE), a power headroom reporting (PHR) procedure in a wireless communication system. The UE determines whether at least one PHR has been triggered and not canceled, and whether an uplink (UL) resource can accommodate a PHR media access control (MAC) control element (CE) plus its subheader as a result of a logical channel prioritization (LCP). The UE transmits the PHR MAC CE, if it is determined that the at least one PHR has been triggered and not canceled, and that the UL resource can accommodate the PHR MAC CE plus its subheader.
