Abstract: Disclosed is a connection management method for mobile device group, where the mobile device group includes a mobile device configured as a leader and a number of mobile devices configured as followers. The connection management method includes: in response to a measurement control from a first base station, the leader acquires signal quality measurement reports of all the mobile devices in the mobile device group corresponding to the first base station and a second base station, and signal quality measurement reports of all the followers in the mobile device group corresponding to the leader; the first base station determines whether to perform a handover according to the signal quality measurement reports received from the leader; and when the first base station determines to perform the handover, the first base station determines to perform a joint handover procedure or a half handover procedure according to the signal quality measurement reports.

Abstract: A user equipment (UE) is configured with at least one bandwidth part (BWP) specific configuration information. The UE receives a configuration information specific to the bandwidth part (BWP). The configuration information configures an initial value of a beam failure detection (BFD) timer and a beam failure indication (BFI) count threshold. The UE starts or re-starts the BFD timer from the initial value when receiving a beam failure indication (BFI) from a lower sublayer, and counts a number of the received BFIs using a BFI counter. The UE resets the BFI counter to zero when receiving a reconfiguration information. The reconfiguration information, that is specific to the BWP, re-configures at least one of the initial value of the BFD timer and the BFI count threshold.

Abstract: Some of the present embodiments provide a method for a random access procedure for a user equipment. The method receives a backoff indicator (BI). After receiving the BI, the method selects a configured contention-free random access (CFRA) preamble from one or more CFRA preambles that have been configured to the UE by a base station. The selected configured CFRA preamble corresponds to synchronization signal block (SSB) candidate detected by the UE. The method then transmits the selected CFRA preamble to the base station.

Abstract: A method includes triggering, by a Medium Access Control (MAC) entity of a User Equipment device (UE), a first Scheduling Request (SR) procedure for a first logical channel, wherein the first logical channel is not configured with a valid Physical Uplink Control Channel (PUCCH) resource for the first SR procedure; and performing, by the MAC entity of the UE, a plurality of procedures in response to triggering the first SR procedure, wherein the procedures includes: initiating a Random Access (RA) procedure and canceling the first SR procedure.

Abstract: The disclosure is directed to a device to device (D2D) mobility management method applicable to a network entity and a user equipment and related apparatuses. In one of the exemplary embodiments, the disclosure is directed to a device to device (D2D) mobility management method used by a network entity. The method would include not limited to transmitting a service request message which includes an application identifier (ID) and a traffic type ID, receiving a first measurement report including a signal quality measurement which is measured based on the service request message, determining a topology type ID and a communication type ID in response to receiving the first measurement report, transmit an access request message which comprises the topology type ID, the communication type ID, and the traffic type ID, and receive an authorization of a network slice in response to transmitting the access request message.
