Abstract:
There is provided a method for operating time alignment timer (TAT). The method may comprise: operating a first TAT in a first medium access control (MAC) entity; operating a second TAT in a second MAC entity; and if the first TAT operated in the first MAC entity is expired, considering the second TAT operated in the second MAC entity as expired.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing measurement objects in the wireless communication system, the method comprising: receiving measurement configuration indicating an object to be measured; determining activating or deactivating measurement of the object depending on an activation condition; and measuring the object when the measurement of the object is activated.
Abstract:
A method and apparatus for applying autonomous denial in a wireless communication system is provided. A user equipment (UE) counts the number of aggregated denials of uplink (UL) subframes in all serving cells or each serving cell over a validity period including previous subframes and a current subframe. If the number of aggregated denials of UL subframes in all serving cells or each serving cell is less than a threshold, the UE is allowed to deny scheduled UL transmission at the current subframe.
Abstract:
A method of transmitting and receiving a signal to and from a network at a user equipment (UE) in a wireless communication system. The method includes steps of logging information about failure of a first connection establishment procedure if the first connection establishment procedure with the network has failed, and transmitting the logged information to the network when a second connection establishment procedure with the network is successful.
Abstract:
One embodiment provides a method for performing a mobility related procedure. The method may comprise: transmitting, by the UE configured with a 2nd/3rd generation mobile communication capability and 4th generation mobile communication capability, a mobility management request message to a first network entity in the 4th generation mobile communication network of a visited public land mobile network (VPLMN); receiving, by the UE and from the first network entity, a mobility management reject message including a rejecting cause value, a first timer and a second timer; if the rejecting cause value indicates that there is no suitable cell in the VPLMN, starting the first timer included in the mobility management reject message; if the first timer is expired, starting the second timer; and until the second timer is expired, disabling the 4th generation communication capability.
Abstract:
A method and apparatus for transmitting information on interference for a device-to-device (D2D) connection in a wireless communication system is provided. A first mobile device detects interference on subframes allocated to a connection with a second mobile device, and transmits information on the subframes in which the interference is detected, to either the second mobile device or a network.
Abstract:
A method and apparatus for transmitting mobility-related information in a wireless communication system is provided. A user equipment (UE) receives a configuration for transmission of mobility-related information from a network during connection establishment, and transmits the mobility-related information to the network based on the configuration of the transmission of the mobility-related information.
Abstract:
Provided is a method for a terminal to report mobility state information in a wireless communication system. The method comprises estimating a mobility state, grouping the estimated mobility state in order to calculate a mobility group state, and reporting mobility state information relating to the mobility group state to a network.
Abstract:
A method and apparatus for controlling uplink transmissions on Discontinuous reception (DRX) operation are provided. A wireless device chooses that a Channel Quality Indicator (CQI)/Precoding Matrix Index (PMI)/Rank Indicator (RI)/Precoding Type Indicator (PTI) on a Physical Uplink Control Channel (PUCCH) are not reported at a subframe n if an onDurationTimer is determined to be not active at the sub-frame n. An uncertainty about the uplink control information during the On Duration occurred by previous DRX operation can be resolved.
Abstract:
A method for operating a serving cell by a user equipment (UE) in a wireless communication system is disclosed. Specifically, the method comprises the steps of: forming a plurality of secondary cells (SCells), as one group, corresponding to a same frequency band through an upper layer; setting an enabled first SCell among the plurality of SCells as the serving cell and transmitting and receiving signals with a network; receiving a serving cell configuration message from the network to disable the first Scell and enable a second SCell; and setting the enabled second SCell as the serving cell and transmitting and receiving signals with the network.
