Embodiment Construction

[0148] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0149] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps closely related to the ...

Abstract

Disclosed are a signal transmission method and apparatus, wherein the method comprises: a terminal using pre-determined spectrum resources on a carrier wave or small cell receives a signal, and confirms whether the received signal belongs to a service carrier wave/service small cell of the terminal; in the affirmative, the terminal, on the basis of the received signal and/or further received signals, carries out measurement and/or data transmission. The present invention, by means of the terminal confirming whether the current received signal is a service base station or service small cell signal, and when so, then carrying out measurement and/or data transmission, avoids the terminal receiving erroneous data or carrying out measurement and/or data transmission based on erroneous data, and therefore overcomes the problem of declining system performance and enables reasonable use of pre-determined spectrum resources.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a signal transmission method and device. Background technique [0002] With the continuous growth of mobile data traffic, spectrum resources are becoming more and more tight. Only using authorized spectrum resources for network deployment and service transmission may not be able to meet the traffic demand. Therefore, the Long Term Evolution (LTE, Long Term Evolution) system can be considered in Transmission is deployed on unlicensed spectrum resources (Unlicensed LTE, referred to as U-LTE or LTE-U) to improve user experience and expand coverage. [0003] (1) Synchronization signal and reference signal in LTE system [0004] The reference signal (RS, Reference Signal) in the LTE system may include a cell-specific reference signal (CRS, Cell-specific Reference Signal), a UE-specific reference signal (UE-specific Reference Signal, UE-RS, also known as DMRS, DeModulation Refer...
