Abstract

The invention discloses a method and device for sending synchronizing signals. The problem that system implementation cost is high due to an existing wireless communication standard is solved. The sending method is applied to a communication system applying an LTE series standard and comprises the steps that a network side network element generates enhanced synchronizing signals; the network side network element sends the enhanced synchronizing signals to an enhanced terminal, wherein the time-frequency resource used in the enhanced synchronizing signals is different from the time-frequency resource used in basic synchronizing signals. The device comprises a generating module and a sending module. According to the method and device for sending the synchronizing signals, a synchronizing channel of the LTE series standard is enhanced, the power consumption and the implement complexity of the terminal can be effectively lowered, cost is also lowered, and the demands of high-speed development data users and wireless communication industry future development can be better met.

Description

technical field

[0001] The invention belongs to the field of communication, and in particular relates to a method and device for sending a synchronization signal. Background technique

[0002] With the development of the mobile Internet and the popularization of smart phones, the demand for mobile data traffic is increasing rapidly, and the rapid growth of data services poses a severe challenge to the transmission capacity of mobile communication networks. According to the prediction of authoritative organizations, in the next ten years (2011-2020), the mobile data business volume will double every year, and will increase by a thousand times in ten years.

[0003] Most mobile data services mainly occur indoors and hotspot environments, which are reflected in nomadic / local wireless access scenarios. According to statistics, nearly 70% of the current mobile data traffic takes place indoors, and this proportion will continue to grow, and it is expected that by 2012 it will exc...
