Embodiment Construction

[0051] When a hierarchical distributed base station contains two types of nodes, wireless equipment (PS_RE: Paired Spectrum based Radio Equipment) nodes using paired spectrum and wireless equipment (US_RE: Unpaired Spectrum based Radio Equipment) nodes using unpaired spectrum, It constitutes a heterogeneous hierarchical distributed base station, which can produce more than traditional radio equipment nodes of the same type (for example, FDD (Frequency Division Duplex, frequency division duplex) radio nodes that only use paired spectrum, or only use non- The layered distributed base station composed of TDD (Time Division Duplex, Time Division Duplex) radio nodes of the paired frequency spectrum is a more flexible duplex mode.

[0052] The present invention proposes a layered heterogeneous distributed base station that uses paired and non-paired spectrum comprehensively. The layered heterogeneous distributed base station that uses paired and non-paired spectrum includes, see fig...

Abstract

The invention provides a hierarchical heterogeneous distributed base station system, which comprises a wireless equipment control node, at least one FDD wireless equipment node using paired frequency spectrum and at least one TDD wireless equipment node using unpaired frequency spectrum; the wireless equipment control node configures an uplink / downlink service channel for a terminal which has communication with a hierarchical heterogeneous distributed base station in the TDD wireless equipment node and configures a control channel matched with the uplink / downlink service channel in the FDD wireless equipment node, thereby realizing hybrid duplexing between the hierarchical heterogeneous distributed base station and the terminal. The invention also provides a method for allocating the frequency spectrum resource, allocates the frequency spectrum for a plurality of duplexing modes and determines the duplexing mode of the terminal to allocate the channel resource for the terminal.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a layered heterogeneous distributed base station and method. Background technique [0002] Compared with traditional centralized base stations, distributed base stations have the advantages of low network construction costs, flexible networking, and high spectrum efficiency. At present, distributed base stations have been commercially used in different cellular mobile communication systems. As the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) long-term evolution (LTE: Long Term Evolution) system evolves to the IMT-Advanced (International Mobile Telecommunications-Advanced, Advanced International Mobile Communications) system, the distributed base station will be in It is more widely used in the IMT-Advanced system.
