Embodiment 1

[0024] In this embodiment, a broadcast channel configuration method for a large bandwidth system is provided.

[0025] Such as figure 1 As shown, the broadcast channel configuration method of the large bandwidth system according to this embodiment includes the following processing:

[0026] Step S102, configure the main broadcast channel in the middle frequency band (also called the center frequency band) / main carrier of the large bandwidth system, and configure the broadcast channel information of the system and / or the dynamic broadcast channel information of the system on the main broadcast channel, and in the middle Broadcast channel information of the frequency band / main carrier;

[0027] Step S104, configuring a secondary broadcast channel or a dynamic broadcast channel on the middle frequency band / primary carrier and / or other frequency bands / secondary carriers of the large bandwidth system.

[0028] Details of the above processing are specifically described below.

Embodiment 2

[0039] In this embodiment, a method for reading broadcast channel information of a large bandwidth system is provided.

[0040] The method for reading broadcast channel information of a large bandwidth system according to this embodiment includes: according to its operating frequency band / carrier, the terminal is in the middle frequency band / main carrier of the large bandwidth system or further in other frequency bands / secondary carriers other than the middle frequency band / main carrier Read broadcast channel information.

[0041] Details of the above processing are specifically described below.

[0042] In the above broadcast channel information reading method, if the main broadcast channel of the system is not configured with other frequency bands / secondary carriers on the secondary broadcast channel and / or frequency band / carrier information of the dynamic broadcast channel, the broadcast channel information reading method further includes: When the operating frequency band...

Abstract

The invention discloses a broadcast channel allocation method and an information reading method for wide bandwidth system. The broadcast channel allocation method for the wide bandwidth system comprises the following steps of: allocating a primary broadcast channel in a middle frequency band / primary carrier of the wide bandwidth system and allocating system broadcast channel information and / or system dynamic broadcast channel information and the broadcast channel information in the middle frequency band / primary carrier to the primary broadcast channel; and allocating a secondary broadcast channel or dynamic broadcast channel in the middle frequency band / primary carrier and / or other middle frequency bands / secondary carriers of the wide bandwidth system. According to technical scheme, the wide bandwidth system uses different BCHs to transmit different kinds of channel information to allow wide bandwidth terminals or narrow bandwidth terminals to completely read BCH information, and theproblem the wide bandwidth system cannot be backward compatible with the narrow bandwidth terminals in the prior art is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a broadcast channel configuration method and an information reading method of a large bandwidth system. Background technique [0002] Currently, the fourth generation (4G) wireless communication system has appeared, which has higher spectrum efficiency than the third generation (3G) wireless communication system. However, due to the need for smooth evolution of the wireless communication system, within a certain period of time, the fourth-generation wireless communication system and the third-generation wireless communication system (such as time division synchronous code division multiple access system or 802.16E system, etc.) will be compatible or coexist. [0003] The bandwidth of the 4G wireless communication system can be as high as 100MHz. The large bandwidth system should meet the following requirements in the case of the most cost-saving, that is, enable the user equipm...
