Abstract: A method for reporting minimization of drive tests measurement data is disclosed. The network assigns a preamble dedicated to the reporting of the logged MDT measurement data. The UE in the idle mode may therefore report the logged MDT measurement data in the appropriate situation. The UEs perform the first random access procedure with the network to obtain the uplink resource and a dedicate indicator for performing the second random access procedure. The UEs perform the second random access procedure for transmitting the request message. The network transmits the response message with a scheduling plan according to the request message(s). The UE transmits the logged MDT measurement data according to the scheduling plan.

Abstract: A method and a user equipment of performing resource switching in an unlicensed spectrum are provided. A current set of resources in the unlicensed spectrum is utilized by a UE for performing LBT attempts for transmission of an RACH message to a base station. One or more LBT attempts for transmissions from the UE to the base station are performed over the current set of resources during a current RACH procedure. The current set of resources is switched to a new set of resources in the unlicensed spectrum to be utilized by the UE in a new RACH procedure after a failure count reaches a pre-configured threshold during the current RACH procedure. The failure count is calculated at least based on a count of LBT failure over the current set of resources during the current RACH procedure.

Abstract: A user equipment (UE), a communication system, and a handling method for handover failure are provided. The handover procedure of the UE from a source cell to one or more configured target cells fail. In the method, in response to the handover procedure failing, a cell selection procedure to select a suitable cell is performed, where the cell selection procedure is configured to perform a connection re-establishment procedure. Whether to continue the connection re-establishment procedure is determined according to a determining result of whether a suitable cell is one configured target cell.

Abstract: The present disclosure proposes a method of allocating resources for a scheduling request (SR), a user equipment using the same method, and a control node using the same method, which is related to dynamically adjusting a dedicated SR (D-SR) period which is a semi-persistently configured D-SR resource used to transmit a SR. The method, the user equipment, and the control node would perform functions including establishing a connection between the user equipment and the control node in order to transmit uplink data, the user equipment transmitting through the connection an assisting information to the control node after establishing the connection to adjust the D-SR period, and the user equipment obtaining a second D-SR period after transmitting the assisting information to the control node.

Abstract: An accessing failure event reporting method, UE, a method for adjusting access control mechanism and a control node are proposed. The accessing failure event reporting method includes: receiving a configuration signal when the UE is preparing into idle mode; performing an accessibility measurement of a GBR mechanism in response to the configuration signal. The accessibility measurement includes: attempting to establish a GBR traffic connection; recording at least one accessing failure event if the UE fails to establish the GBR traffic connection; and reporting the at least one accessing failure event.

Abstract: A method and an apparatus for notifying activations of extended access barring (EAB) and updates of EAB information in the field of Long Term Evolution (LTE) wireless communication systems have been proposed. In accordance with the present disclosure, the eNB notifies MTC devices of EAB changes from a paging message through the paging channel (PCH). The network could use either a single bit EAB status indicator to notify whether the EAB has been enabled or disabled or use multiple bits EAB indicator to represent different EAB parameter changes in addition to whether the EAB has been enabled or disabled. Based on the present disclosure, the network could reduce the paging overhead by require the MTC device to acquire the EAB-SIB only when it needs the EAB information.
