[0045] The wireless communication system can support multiple wireless transmission systems, including Global System of Mobile communication (Global System of Mobile communication, GSM), Wideband Code Division Multiple Access (WCDMA), Time Division Synchronous Code Division Multiple Access (TCDMA) Time Division-Synchronous Code Division Multiple Access, TD-SCDMA), Long Term Evolution (Long Term Evolution, LTE), Wireless Local Area Networks (Wireless Local Area Networks, WLAN), etc.; the wireless communication system can support signals of any of the above standards The processing can also support the mix...

Embodiment 2

[0075] In the wireless communication system described in the embodiment of the present invention, the AU subsystem can be networked in a cascade manner, such as image 3 As shown, it is a schematic structural diagram of a wireless communication system that adopts a cascaded networking mode of AU subsystems. The wireless communication system includes a GW subsystem, multiple EUs, at least one RU connected to each EU, and multiple AU subsystems. Each AU subsystem also includes a cascade interface.

[0076] Specifically, each AU subsystem is connected sequentially through a local cascading interface, wherein the AU subsystem arranged first and the last AU subsystem are connected to one AU subsystem through a local cascading interface, The remaining AU subsystems are respectively connected to the two AU subsystems through local cascading interfaces, and each AU subsystem is also connected to its corresponding EU. Generally, each AU subsystem is connected to the GW subsystem.

Abstract

The invention discloses a wireless communication system and a wireless communication method for a flat network architecture, and an extend unit. The wireless communication system comprises access unit (AU) subsystems, the EU and at least one radio remote unit (RU) connected with the EU. The EU is used for converting a downlink baseband high-speed signal transmitted by the AU subsystem into a downlink sub-baseband low-speed signal, and transmitting the downlink sub-baseband low-speed signal to the RU, so that the EU can be connected with the RU by a low-speed transmission link such as a category-5 cable, indoor coverage is facilitated, and difficulty and cost in network deployment are reduced; the wireless communication system supports the concatenation and stacking mode of the AU subsystems, so that the capacity extensibility of the system is improved; and in addition, the wireless communication system also can comprise a gateway (GW) subsystem, and the function of a radio network controller (RNC) is shifted down to the GW subsystem and the AU subsystem to further disintegrate and simplify the structure of the whole communication system, so that a network processing time delay and a transmission time delay are shortened.
