Embodiment Construction

[0027] The present invention provides a design scheme of a common control channel, which enables the large bandwidth system to meet the bandwidth requirements of the compatible system, and enables the compatible terminal to work normally and reliably, and solves the problem that the large bandwidth system in the prior art cannot reliably and effectively Issues with backward compatibility.

[0028] The embodiment of the present invention provides a method for implementing backward compatibility of a large bandwidth system. In the present invention, the design of the common control channel should consider at least two aspects of design, that is, design of a synchronous channel (Synchronous Channel, SCH) and design of a broadcast channel (Broadcast Channel, BCH). specifically, figure 1 A flowchart of the method is given. Such as figure 1 As shown, the implementation method of the backward compatibility of the large bandwidth system according to this embodiment includes the fol...

Abstract

The invention discloses a method for realizing large bandwidth backward compatibility, comprising the following steps of allocating the synchronous channel of the large bandwidth system according to the synchronous channel of a compatible system; allocating the broadcast channel of the large bandwidth system according to the broadcast channel of the compatible system; and adding a new broadcast channel or a system information block for the large bandwidth system. By using the invention, the large bandwidth system can satisfy the requirement that the compatible system can work efficiently and reliably to achieve the purpose that the large bandwidth system can realize backward compatibility for terminals of small bandwidth efficiently and reliably by allocating the public control channel ofthe large bandwidth system according to the compatible system.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for realizing backward compatibility 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 equipment (User Equipment, UE) w...
