Problems solved by technology

[0007] In the prior art, the terminal cannot determine the number of discovery resources used by the sender, and cannot determine the detection based on the number of discovery resources, so performance loss may be caused by the mismatched number of discovery resources; if the terminal performs blind detection on all possible discovery resources , it will increase the detection complexity

Embodiment Construction

[0048] The embodiment of the present invention provides a D2D signal detection scheme. In the embodiment of the present invention, the D2D terminal determines the number of discovery resources used by the discovery signal according to the physical resources of the detection discovery signal or the detection result of the discovery sequence. The number of resources to perform discovery signal detection.

[0049] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0050] see figure 2 , which is a schematic diagram of a D2D signal detection process provided by an embodiment of the present invention, and the process may include:

[0051] Step 201: The terminal determines a physical resource area for detecting a discovery signal.

[0052] The terminal here refers to a discovery terminal, that is, a terminal that receives a discovery signal. The discovery signal here may include a discovery sequence and / or a dis...

Abstract

The invention discloses a D2D signal detection method and equipment. The present invention includes: the terminal determines the physical resource area for detecting the discovery signal; the terminal detects the physical resource area of ​​the discovery signal, or detects the discovery resource of the discovery sequence contained in the discovery signal in the physical resource area Set, determine the number of discovery resources used by the discovery signal, the number of discovery resources is the number of discovery resources used to send the same discovery signal within one discovery period or within the physical resource area; the terminal according to the determined number of discovery resources, Detection of the discovery signal is performed. Adopting the present invention can improve the performance loss caused by D2D signal detection, and can reduce the complexity of terminal detection D2D signal.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a D2D signal detection method and device. Background technique [0002] D2D (Device-to-Device, device-to-device), that is, terminal direct technology, refers to the way that adjacent terminals can transmit data through direct links within a short distance, without forwarding through central nodes (ie base stations) . [0003] LTE D2D (Long Term Evolution D2D) technology refers to the D2D discovery and communication process that works in the LTE (Long Term Evolution, Long Term Evolution) licensed frequency band and is controlled by the LTE network. The introduction of the LTE D2D feature will make the LTE technology evolve from a pure wireless mobile cellular communication technology to a "universal connectivity technology (Universal Connectivity Technology)". [0004] LTE D2D technology includes two aspects of D2D discovery and D2D communication, wherein ...
