Abstract:
A method and apparatus for receiving an indication of system information change in a wireless communication system is provided. An indication of system information change per system information category is proposed. A user equipment (UE) receives an indication of system information change for a specific system information category which related to a specific usage of system information from a network, and verifies whether the specific system information category has changed according to the indication of system information change for the specific system information category. If verified, the UE receives updated system information included in the specific system information category from the network.
Abstract:
A method and apparatus for receiving system information (SI) in a wireless communication system is provided. A user equipment (UE), which may be in an enhanced coverage or operate with a narrower bandwidth than a cell bandwidth, receives an indication of at least one of SI update, earthquake and tsunami warning system (ETWS) notification, commercial mobile alert system (CMAS) or extended access barring (EAB) modification via a physical downlink control channel (PDCCH) from a network, and receives system information according to the received indication from the network.
Abstract:
A method for processing signals at a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of receiving a relay configuration message from a network via a dedicated signaling, the relay configuration message including at least one condition for which the UE considers itself as a valid relay; performing relay functions when the at least one condition is met; and transmitting a notification message for notifying an expiration of functioning as the valid relay to the network when the at least one condition is not met.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for indicating a priority in a D2D communication system, the method comprising: receiving a SDU with a priority corresponding to the SDU from an upper layer; generating a PDU including the SDU and the corresponding priority; and transmitting the PDU to a peer device.
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for changing a connection by a user equipment (UE) connected with a relay UE through a device to device (D2D) link in a wireless communication system, the method comprising: receiving information on a threshold value through a broadcast signaling; measuring a quality of a channel from a cell; establishing a radio resource control (RRC) connection with the cell when the measured quality is higher than the threshold value; and releasing the D2D link with the relay.
Abstract:
A method and apparatus for receiving system information in a wireless communication system is provided. A user equipment (UE) receives an indication indicating whether a cell supports a short transmission time interval (TTI) from the cell, and receives at least one of normal TTI system information in a normal TTI or short TTI system information in the short TTI from the cell according to the received indication. That is, an eNodeB (eNB) may schedule separate system information block type 1 (SIB1) and/or SI messages broadcast in short TTI.
Abstract:
A method for changing a coverage enhancement mode in a wireless communication system supporting a coverage enhancement (CE) is disclosed. For this, the method comprising: receiving, from a network, information on a CE mode level supported by the network, wherein the information on the supported CE mode level indicates a highest level among CE mode levels currently supported by the network; determining a CE mode level of the UE; and transmitting, to the network, a first message for requesting a change of the supported CE mode level, when the determined CE mode level of the UE is higher than or equal to the supported CE mode level.
Abstract:
A method and apparatus for performing autonomous denial for dual connectivity in a wireless communication system is provided. A user equipment (UE) receives an autonomous denial rate from a network, and applies the received autonomous denial rate to at least one of a master cell group (MCG) or a secondary cell group (SCG). THe UE is connected to both a master evolved NodeB (MeNB), associated with the MCG, and a secondary eNB (SeNB), associated with the SCG, in dual connectivity.
Abstract:
A method and apparatus for routing traffic in a wireless communication system is provided. A user equipment (UE) transmits information on the routing of the traffic to a network, and routes the traffic to at least one of 3rd generation partnership protocol (3GPP) long-term evolution (LTE) or wireless local area network (WLAN), according to the information on routing of the traffic. The information on the routing of the traffic may be a ratio of an amount of the traffic to be served by the 3GPP LTE and an amount of the traffic to be served by the WLAN, or a preferred WLAN throughput.
Abstract:
A method and apparatus for updating an access network discovery and selection functions (ANDSF) policy in a wireless communication system is provided. A user equipment (UE) receives the ANDSF policy and radio access network (RAN) assistance information for the ANDSF policy and a RAN rule, and further receives a configuration indicating whether both the ANDSF policy and the RAN rule are utilized for access network selection and traffic routing. Only if the received configuration indicates that the RAN rule is not utilized for the access network selection and traffic routing, the UE updates the ANDSF policy based on the received RAN assistance information, and performs the access network selection and traffic routing based on the received configuration.
