A method performed by a user equipment (UE) in a wireless communication system, includes triggering a first power headroom report (PHR), wherein a first PHR media access control (MAC) control element (CE) is not transmitted when first uplink (UL) resources cannot accommodate the first PHR MAC CE plus its subheader, triggering a second PHR, determining whether at least one PHR has been triggered and not cancelled and transmitting a second PHR MAC CE when it is determined that the at least one PHR has been triggered and not cancelled, and when second UL resources can accommodate the second PHR MAC CE plus its subheader.

Method and apparatus for performing power headroom reporting procedure in wireless communication system

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.

A method and apparatus for performing a membership verification or an access control in a wireless communication system is provided. A mobility management entity (MME) performs the membership verification or the access control of a user equipment (UE), and transmits verified UE membership information to a target HeNB.

Method and apparatus for performing membership verification or access control in wireless communication system

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).

Provided are a method and an apparatus for transmitting a multimedia broadcast/multicast service (MBMS) interest indication message in a wireless communication system. A user equipment (UE) receives from a first base station system information for an MBMS which is broadcasted, and transmits the MBMS interest indication message to the first base station when the user equipment performs a handover from a second base station, which does not broadcast the system information for the MBMS, to the first base station.

Method and apparatus for transmitting service interest indication message in wireless communication system

A user equipment (UE) and method are provided for transmitting an in-device coexistence (IDC) indication message in a wireless communication system. The UE receives a configuration message including an IDC indication from a base station. The UE transmits an IDC indication message to the base station if the UE determines that the IDC indication contains specific information. The specific information comprises an activation bit. The presence of the activation bit in the configuration message represents permission for the UE to transmit the IDC indication message. The IDC indication message includes frequency division multiplexing (FDM) assistant information. The FDM assistant information includes information on an unusable frequency in which interference from a long-term evolution (LTE) module in the UE to other coexisting technology modules in the UE or interference from other coexisting technology modules in the UE to the LTE module in the UE is expected.

Method and apparatus for limiting transmission of in-device coexistence indication message in wireless communication system

A method of segmenting input speech signal into plurality of frames for speech recognition is disclosed. The method includes extracting a low frequency signal from the speech signal, and segmenting the speech signal into a plurality of time-intervals according to a plurality of instantaneous phase-sections of the low frequency signal.

Nested segmentation method for speech recognition based on sound processing of brain

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.

Apparatus and method of reporting logged measurement in wireless communication system

A method for communicating between a user equipment (UE) and a network in a wireless communication system, the method includes receiving, by the UE, a first multimedia broadcast multimedia service (MBMS) service from a first cell on a first frequency while the UE is in an idle mode; receiving, by the UE, a first system information block (SIB) from the first cell on the first frequency, the first SIB including information on an MBMS service area (SA) provided at a second frequency; receiving, by the UE, a second SIB from a second cell on the second frequency, the second SIB including information on a multimedia broadcast multicast single frequency network (MBSFN) area; and receiving, by the UE, a second MBMS service from the second cell on the second frequency, based on the received information on the MBSFN area.

Method and apparatus for acquiring service area information in wireless communication system

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.

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.

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.
