Abstract:
A method and apparatus of reporting logged measurements of an user equipment in a wireless communication system is provided. The user equipment in a Radio Resource Control (RRC) connected mode receives from a base station a Minimization of Drive Tests (MDT) configuration. The user equipment transitions from the RRC connected mode to an RRC idle mode and logs measurements based on the MDT configuration. The user equipment transmits to the base station a logging indicator indicating an availability of the logged measurement.
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:
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:
Provided is a method for reporting positioning status by a terminal in a wireless communication system. The method comprises: confirming a positioning status related to whether location information of a terminal can be provided; and when the positioning status is confirmed, transmitting a positioning status reporting message via a network. The positioning status reporting message comprises positioning status information indicating the positioning status of the terminal.
Abstract:
A method is provided for transmitting an uplink signal by a user equipment (UE). The UE receives a first uplink grant including a first new data indicator (NDI) from a network, determines whether the first NDI has been toggled by comparing the first NDI to a second NDI, and transmits the uplink signal based on a result of the determining to the network. The second NDI is included in a second uplink grant that was previously received. The second uplink grant was identified by an identifier except for a temporary cell identifier.
Abstract:
A method and apparatus for releasing delay tolerant access user equipments (UEs) in a wireless communication system is provided. An eNodeB (eNB) receives an overload message or a user equipment (UE) context release command message including a request for releasing the delay tolerant access UEs from a mobility management entity (MME), releases the delay tolerant access UEs based on the overload message or the UE context release command message.
Abstract:
A method of receiving a service from a network in a mobile communication system in accordance with the present invention comprises receiving static scheduling information from a network, the static scheduling information including information on radio resources associated with combining reception, receiving dynamic scheduling information from the network, the dynamic scheduling information including control information for receiving the service, and receiving the service by combining downlink shared channels transmitted from a plurality of cells based on the static scheduling information and the dynamic scheduling information.
Abstract:
There is provided with a method for enabling a user equipment to perform a random access procedure in a wireless communication system. The method includes transmitting a random access preamble and receiving a random access response as a response to the random access preamble. The random access response is addressed by a random access identifier. The random access identifier is mapped to radio resources used for transmitting the random access preamble. The user equipment can immediately confirm its random access response and perform further efficient random access procedure.
Abstract:
A method of transmitting and receiving control information in a wireless communication system is disclosed. The method of receiving control information related to a specific point-to-multipoint service in a user equipment of a wireless communication system comprises receiving a notification message including indication information and an identifier identifying the point-to-multipoint service from a network, the indication information indicating at least one downlink channel related to the specific point-to-multipoint service among a plurality of downlink channels established for transmission of control information for at least one or more point-to-multipoint service, and receiving at least one downlink channel indicated by the indication information.
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.
