The method comprises the steps that a resource searching request is received; in response to the resource search request, acquiring an alias library and a cleaning name library corresponding to each resource in a resource library; determining the matching degree between the resource search request and the corresponding resource through each alias in the alias library and each cleaning name in the cleaning name library; according to the matching degree, determining a preset number of resources from the resource library as search resources; and determining the search resource as a search result.

Physical downlink control channel monitoring scaling

A user equipment (UE) monitors a physical downlink control channel (PDCCH) in a plurality of component carriers (CCs). The UE determines whether the UE is operating in a carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating with a CA having a first CC in a first frequency band and a second CC in a second frequency band, the UE determines a span pattern of PDCCH symbols received on the first CC and the second CC, and selects a PDCCH monitoring type based at least on the span pattern. The UE also determines whether the first and second CCs of the CA combination are co-located and selects a PDCCH monitoring type based at least on determining whether the first and second CCs are co-located.

Machine tool cutter, cutter handle design method and cutter

The invention discloses a machine tool cutter, a cutter handle design method and a cutter, and relates to a cutter for a machine tool. According to the design indexes of the tool, a three-dimensional model of a first version of the tool is established, and the first version of the three-dimensional model comprises a tool handle, a tool bar and a tool bit; the cutter bar comprises a cutter head end and a cutter handle end; establishing a cutter dynamics finite element model, and performing modal finite element analysis and harmonic response finite element analysis; if the design indexes are not met, the structure and the material of the cutter bar are adjusted, and modeling is conducted again; and the finite element dynamical model meets the design requirements. The design of the cutter bar can be completed by iteration with limited times; after the designed cutter bar is combined with the cutter and the cutter handle, a good vibration reduction effect is achieved.
