Abstract:
A method for measuring performed by a user equipment (UE) in a wireless communication system is provided. The method includes: camping on a serving cell operating on a serving frequency; receiving a reselection priority information, the reselection priority information indicating signaled priorities for the serving frequency and a inter-frequency; determining whether to apply an implicit highest priority to the serving frequency for measurement; and measuring the inter-frequency based on the signaled priorities. The step of the determining comprises: wherein if the UE receives a logged measurement configuration for a logged Minimization Driving Test (MDT) and a type of the serving cell is a predetermined type, determining to apply a signaled priority for the serving frequency indicated by the reselection priority indication.
Abstract:
A reporting method by a user equipment (UE) in a wireless communication system is provided. The method includes: measuring at least one cell; detecting whether or not interference is occurred during the measurement; and transmitting a report message to a network. When it is detected that interference occurs during the measurement, information regarding the interference generated during the measurement is included in the report message and transmitted.
Abstract:
A method and apparatus of performing a handover procedure in a wireless communication system is provided. The target eNodeB (eNB) receives a specific establishment cause of a user equipment (UE). The specific establishment cause among a plurality of establishment causes comprises emergency, high priority access, mobile terminated access, mobile oriented signaling, mobile oriented data, and delay tolerant access. The target eNB transmits a handover command message to the UE after receiving the specific establishment cause.
Abstract:
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.
Abstract:
A method for a user equipment (UE) to generate a transmission is provided. In this method, a UE starts a time alignment timer when a time alignment command is received. The UE receives an uplink grant; and generates an initial transmission or a retransmission according to the uplink grant only when the time alignment timer is running upon receiving the uplink grant. In addition, the uplink grant is received through a Physical Downlink Control Channel (PDCCH) indicated by a Cell Radio Network Temporary Identifier (C-RNTI) of the UE.
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 is provided for performing, by a user equipment (UE), a power headroom reporting (PHR) procedure in a wireless communication system. In a first PHR procedure, a first PHR is triggered, and it is determined that a first uplink (UL) resource cannot accommodate a PHR media access control (MAC) control element (CE) plus its subheader. The PHR MAC CE is not transmitted in the first PHR procedure and it is determined that the first PHR is not cancelled. Further, in a second PHR procedure, a second PHR is triggered, and it is determined that at least one PHR, including the first PHR and the second PHR, has been triggered and not cancelled. It is then determined that a second UL resource can accommodate a PHR MAC CE plus its subheader, and the PHR MAC CE is transmitted by using the second UL resource to an eNodeB (eNB).
Abstract:
A method and apparatus of measuring a packet throughput in a wireless communication system are provided. When determining a reference time for estimating packet throughput, a receiver determines the time that a data burst starts or ends in order to estimate the packet throughput considering a change in the data burst of the transmitter buffer. A measurement period is defined through the determined start time and end time of the data burst, and packet throughput is measured considering the total amount of the received data burst. The throughput of packet data may be estimated by each base station based on the same standard rule, so that the measured packet throughput values may be reliable, thus allowing the operator to make use of it as a parameter for MDT.
Abstract:
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.
Abstract:
Provided is a method for reporting by a terminal in a wireless communication system. The method comprises: acquiring measurement results; starting to acquire location information related to the measurement results; determining whether measurement results satisfy reporting conditions; starting a delay timer; and if the location information is acquired before the delay timer expires, transmitting a reporting message comprising the measurement results and the acquired location information via a network.
