Embodiment 1

[0042]This embodiment introduces a synchronization signal sending device, which is suitable for communication systems using LTE series standards, such as Figure 4 As shown, the device includes: a generating module and a sending module, wherein:

[0043] The generating module is used to generate an enhanced synchronization signal;

[0044] The sending module is configured to send the enhanced synchronization signal to the enhanced terminal, wherein the time-frequency resource used by the enhanced synchronization signal is different from the time-frequency resource used by the basic synchronization signal.

[0045] The enhanced synchronization signal described herein refers to a synchronization signal with different time-frequency resources from the basic synchronization signal (ie, the LTE standard synchronization signal, including the primary synchronization signal and / or the secondary synchronization signal). The "enhanced synchronization signal" is only a name to distingui...

Embodiment 2

[0063] This embodiment illustrates the method for sending and receiving the synchronization signal described herein, which is applied to a communication system using the LTE series of standards, such as Figure 5 As shown, the sending methods include:

[0064] Step 110, the network element on the network side generates an enhanced synchronization signal;

[0065] Step 120, the network element on the network side sends the enhanced synchronization signal to the enhanced terminal, wherein the time-frequency resource used by the enhanced synchronization signal is different from the time-frequency resource used by the basic synchronization signal.

[0066] By enhancing the synchronization channel of the LTE series standards, the power consumption and implementation complexity of the terminal can be effectively reduced, and the implementation cost can be reduced.

[0067] For example, the time-frequency resource used by the enhanced synchronization signal can be located in any of ...

application example 1

[0073] In this example, the time-frequency resource used by the enhanced synchronization signal sent by the base station is located in the OFDM symbol used by the basic synchronization signal, for example, located in Figure 6a , 6b or the position shown in 6c, Figure 6a , 6b , 6c are just examples of locations, and the enhanced synchronization signal can also be located on other subcarriers in the OFDM symbols used by the basic synchronization signal except those shown in the figure.

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...
