Abstract: This disclosure describes methods, systems, and devices for handover of a user equipment (UE) from a source node of a radio access network (RAN) to a target node of the RAN. In one example, a method involves receiving, by the UE and from the source node, a RACH-498 handover message comprising: (i) an uplink grant for establishing a connection with the target node, and (ii) an identifier of a reference signal associated with a beam of the target node. The method also involves performing, by the UE, a handover based on the RACH-less handover message.

Abstract: A handle assembly and a stapler including the same are provided. The handle assembly includes a first handle, a second handle, a slot provided in the second handle and a slider slidably located in the slot. When the slider is in the first section of the slot, the first handle and the second handle are not linked; when the slider is in the second section of the slot, the first handle is linked to the second handle and actuates the second handle to move from an insurance position to a firing position. Therefore, only the movement of the second handle can fire the stapler. No matter whether the stapler is ready to be fired or not, the first handle can be pressed by the doctor, while the stapler cannot be fired when the stapler is not ready to be fired.

Abstract: The present disclosure relates to selecting a Local Management Function (LMF) in a wireless communication network, a next generation Radio Access Network (NG-RAN) acquires a capability from a user equipment (UE), the capability indicating whether the UE is capable of supporting LMF in Radio Access Network (RAN). An access and mobility management function (AMF) is then notified whether the UE is capable of supporting LMF in RAN. An LMF selection is then received from the AMF. Then a response is transmitted to the UE based on the received LMF selection, the response indicating whether a positioning procedure to be carried out by the UE is based on LMF in RAN. In this manner, the capabilities of the UE are taken into consideration when selecting an LMF for a positioning procedure.
