Embodiment Construction

[0086] Embodiments of the present invention provide a method for sending synchronization information, a method for detecting them, and corresponding embodiments. Wherein, the synchronization information includes a synchronization signal and a synchronization channel. Synchronization signals are sent on synchronization signal resources. Synchronization signal resources correspond to multiple synchronization channel resources. Different UEs or different types of synchronization channels can occupy different synchronization channel resources. While ensuring the reliability of synchronization signals, with a small resource overhead Reduces interference between different sync channels in sync transmissions.

[0087] The technical solutions provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Abstract

The invention discloses a synchronization information sending method, a synchronization information detection method and a piece of user equipment. The synchronization information sending method comprises the following steps: a piece of user equipment sends a synchronization signal on a synchronization signal resource; the user equipment selects a synchronization channel resource from multiple synchronization channel resources corresponding to the synchronization signal resource according to the corresponding relationship between synchronization signal resources and synchronization channel resources; and the user equipment sends a synchronization channel on the selected synchronization channel resource. According to the technical scheme provided by the embodiment of the invention, a synchronization signal resource corresponds to multiple synchronization channel resources, and the UE selects one synchronization channel resource to send a synchronization channel, so that different UE can send synchronization channels on different synchronization channel resources, and mutual interference between synchronization channels is avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for sending synchronization information, a detection method and user equipment. Background technique [0002] Device-to-Device (Device-to-Device, D2D), that is, terminal direct technology, means that adjacent user equipment (User Equipment, UE, also known as terminal) can perform data transmission through a direct link within a short distance. It needs to be forwarded through the central node (that is, the base station). [0003] Long Term Evolution (LTE) D2D technology refers to the D2D discovery and communication process that is controlled by the LTE network and works in the LTE licensed frequency band. On the one hand, it can give full play to the advantages of D2D technology, and at the same time, the control of LTE network can also overcome some problems of traditional D2D technology, such as uncontrollable interference. The introduction of ...
