Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for reporting amount of data available for transmission in the wireless communication system, the method comprising: receiving indication information for reporting amount of Data Available for Transmission (DAT); calculating a first amount of DAT and a second amount of DAT based on the indication information; and reporting at least one of the first amount of DAT to a first e-Node B (eNB) or the second DAT to a second eNB.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing random access procedure by a UE (User Equipment) in the a wireless communication system, the method comprising: transmitting random access preamble to the BS (Base Station); receiving response message including UL (Uplink) grant and TTI (Transmission Time Interval) bundling information; and performing UL transmission using the UL grant by TTI bundling operation.
Abstract:
There is provided a method for reporting a power headroom. The method may comprise: establishing, by a user equipment (UE), connections with plural base stations, each of which includes one or more cells; determining, by the UE, a power headroom for at least one base station among the plural base stations; and triggering, by the UE, a power headroom reporting (PHR) including the determined power headroom.
Abstract:
A method of reporting a measurement performed by UE in a wireless communication system is provided. The method includes: performing a measurement and obtaining a first measurement result; and generating information on a first measurement bandwidth related to the first measurement result and transmitting a measurement reporting message to a network. The measurement reporting message includes the first measurement result and the information on the first measurement bandwidth. The information on the first measurement bandwidth is information related to a measurement bandwidth regarding the first measurement result.
Abstract:
A method and apparatus of releasing a connection in a wireless communication system is provided. A user equipment (UE) establishes a radio resource control (RRC) connection with a specific establishment cause, receiving paging indicating connection release and release information including an establishment cause or a logical channel priority, and releasing the RRC connection depending on the establishment cause or the logical channel priority included in the release information.
Abstract:
A method and apparatus for performing backoff in a wireless communication system is provided. A user equipment (UE) identifies a prioritized access, receives a backoff parameter from a network, and determines whether or not to apply the received backoff parameter according to the prioritized access. The prioritized access corresponds to one of emergency access, high priority access, control element/information in media access control (MAC), radio link control (RLC) or packet data convergence protocol (PDCP), data radio bearer (DRB) for voice/video service, signaling radio bearer (SRB) 0, SRB 1, SRB 2, multimedia telephony service (MMTEL)-voice, MMTEL-video, and voice over long-term evolution (VoLTE).
Abstract:
Physical downlink control channel (PDCCH) monitoring scheme considering a enhanced physical downlink control channel (ePDCCH) is disclosed. According to the present invention, when a UE receives a first ePDCCH indicating a downlink transmission at subframe ‘n’ from a network, even though processes the received first ePDCCH until subframe ‘n+m’, wherein m is not 0, the UE is configured to monitor a second ePDCCH or a PDCCH from subframe ‘n+Xrtt’, where ‘Xrtt’ corresponds to a value of a Hybrid Automatic Repeat Request Retransmission timer (HARQ RTT timer).
Abstract:
Provided is an interested service-based cell reselection method performed by a terminal in a wireless communication system. The method comprises checking that access to the current cell is blocked, determining whether the condition for receiving an interested service is satisfied, and selecting, if the condition for receiving an interested service is satisfied, the cell on the same frequency as the frequency of the current cell.
Abstract:
Provided is a method for a terminal controlling access in a wireless communication system. The method comprises: obtaining service-specific access control information; obtaining service group access control information; and controlling access to a specific type of service based on the service group access control information and the service-specific access control information. The service-specific access control information includes a service-specific barring factor parameter which is applied to the specific type of service. The service group access control information includes a service group barring factor parameter which is commonly applied to specific service groups that include at least one type of service.
Abstract:
A method and apparatus for transmitting an indication in a wireless communication system is provided. A user equipment (UE) transmits a first indication according to a first configuration, starts a timer prohibiting transmission of another indication, receives a second configuration, and configures a second indication according to the second configuration after the timer expires.
