Problems solved by technology

Since the existing mobile communication systems are designed based on relatively narrow bandwidth, and do not take into account that the same system needs to support system configurations with different bandwidths, the existing related technologies cannot guarantee that the future broadband mobile communication system will not only meet the requirements of mobile terminal users' fast Access to the system in a timely manner, and avoid interference between synchronization channels and broadcast channels in different cells

Embodiment Construction

[0026] The method for acquiring system information of the present invention and the terminal and wireless base station equipment using the method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] The structure of the usual mobile communication system is as attached figure 1 As shown, the mobile communication system is composed of several wireless communication base stations. These base stations have one or several cells or sectors with certain coverage. These cells form a continuous coverage area during network planning to ensure Good enough wireless signal quality can be provided in the planned area. In the actual network environment, the shape of each coverage cell and the location of the wireless base station are irregular. Generally speaking, in a cell cluster forming a continuous coverage, each cell needs to send a unique message that can be identified by the mobile terminal. The signal is used for the term...

Abstract

The invention provides an information acquiring method for a mobile communicating terminal which includes searching a synchronous sequence signal transmitted by a base station in a downlink synchronous time slot to build a down synchronization; ensuring the location of the broadcasting channel of the base station corresponding to a synchronous sequence signal in a time domain and a frequency domain; receiving the wireless signal transmitted by the broadcasting channel of the base station according to the ensured location to acquire the system information. The invention also provides a terminal and a wireless communicating base station device which adopt the method. The method of the invention acquires a system broadcasting channel and a sub-carrier cluster location that bears the broadcasting channel through identifying the synchronous sequence and can ensure the terminal to quickly and effectively acquire the system information and shorten the time to be accessed into the system. The method can effectively solve the same frequency common-channel interference problem between neighboring synchronous channels and broadcasting channels in a mobile communicating system and is suitable to be adopted in the future broad band mobile communicating system.

Description

technical field [0001] The invention relates to a mobile communication system, especially a base station, a terminal and a method for the terminal to acquire system broadcast information of the mobile communication system in the broadband mobile communication system. Background technique [0002] In the existing second-generation and third-generation mobile communication systems, the bandwidth of the system is relatively narrow. For example, the bandwidth of a typical GSM mobile communication system is only 200kHz. The WCDMA mobile communication system and The bandwidth of TD-SCDMA mobile communication system is 5MHz and 1.6MHz respectively. Due to the limitation of bandwidth, despite the development of multiple-input multiple-output (MIMO) antenna technology and adaptive modulation coding (AMC) technology that can significantly improve spectrum utilization, it is still unable to provide mobile users with transmission rates up to tens of Mbps. The need for communication cap...
