METHOD, SN, BASE STATION, AND SYSTEM FOR CELL COMBINATION BASED ON MULTIPLE SMALLCELL BASE STATIONS

摘要

A method, a Signal NodeB (SN), a NodeB, and a system for performing cell combination based on multiple Smallcell NodeBs are described, and the method includes: an intra-frequency logic cell is established based on a logic NodeB formed by combining multiple Smallcell NodeBs, after the SN receives a cell establishment request of a Radio Network Controller (RNC), wherein, an lub interface control plane of the NodeB is implemented in the SN; a radio link is established between the SN and a corresponding Smallcell NodeB; and data transmission and resource management is performed on the intra-frequency logic cell based on the radio link. The disclosure can avoid RNC expansion caused by plenty of Smallcell NodeB applications, and occurrence of a soft handover between plenty of Smallcells and an lur soft handover across the RNC between a Macrocell and a Smallcell; and can also implement multiplexing of a High Speed-Dedicated Physical Data Channel (HS-PDSCH) code channel resource and improve throughput of an intra-frequency logic cell.
