Embodiment Construction

[0148] Exemplary embodiments of the present invention will hereinafter be described with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in the specification. It should be appreciated, however, that many implementation-specific decisions must be made in the development of any such practical embodiment in order to achieve the developer's specific goals, such as compliance with those constraints associated with the system and business, and these Restrictions may vary from implementation to implementation. Furthermore, it should also be appreciated that while development work can be very complex and time consuming, such development work would 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 device structures and / or p...

Abstract

The present invention discloses a signal transmission method and device, wherein the method includes: a terminal receives a signal on a carrier / cell using predetermined spectrum resources, and confirms whether the received signal belongs to the serving carrier / cell of the terminal; If the confirmation is yes, the terminal performs measurement and / or data transmission according to the received signal and / or further received signals. The present invention enables the terminal to confirm whether the currently received signal is the signal of the serving base station or the serving cell, and only perform measurement and / or data reception when the confirmation is yes, thereby preventing the terminal from receiving erroneous data or based on erroneous signals Measurement and / or data transmission are performed, thereby overcoming the problem of system performance degradation and realizing reasonable utilization of predetermined spectrum resources.

Description

technical field [0001] The present invention relates to the field of communication, and in particular, to a signal transmission method and apparatus. Background technique [0002] With the continuous growth of mobile data traffic, spectrum resources are becoming more and more scarce. Only using licensed spectrum resources for network deployment and service transmission may no longer meet the traffic demand. Therefore, the Long Term Evolution (LTE, Long Term Evolution) system can be considered in Africa. Deploy transmission on licensed spectrum resources (Unlicensed LTE, U-LTE or LTE-U for short) to improve user experience and expand coverage. [0003] (1) Synchronization signal and reference signal in LTE system [0004] A 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 called DMRS, DeModulation Reference) S...
