Abstract: A rapid assembly and automatic sampling drilling tool for frozen soil layer exploration includes a fixed flow divider, a flow guide pipe, a coring pipe and a drill bit. The fixed flow divider is connected to the drill bit through the flow guide pipe and the coring pipe mounted between the fixed flow divider and the drill bit. Two ends of the flow guide pipe communicate with the fixed flow divider and a main flow channel in the drill bit respectively. Hot water in the fixed flow divider can be conveyed into the drill bit through the flow guide pipe and sprayed from a nozzle arranged on the drill bit for drilling and coring operations. An inlet of the coring pipe communicates with a coring channel in an inner cavity in the drill bit, and a core sample drilled by the drill bit is taken out through the coring pipe.

Abstract: A method, base station and user equipment for multicasting and a device with a storage capability are disclosed in the present disclosure. The method for multicasting includes the following steps of: receiving, by a base station, queue state information transmitted in a time division manner by different user equipments (UEs) in a multicast group; and estimating queue state information of at least another part of UEs in the multicast group according to the received queue state information of the UEs. In this way, the present disclosure can enable the resource allocated to each of the UEs by the base station to match the queue state information of the UE, thereby avoiding the waste of resources without influencing the play effect.
