Embodiment 3

[0151] Embodiment 3: Scenario of distributed combination.

[0152] For scenarios where there is no central node and distributed D2D broadcast, the implementation method is as follows Figure 5 shown, including:

[0153] In step 301, the source D2D user equipment sends a D2D broadcast request message on a pre-configured radio resource.

[0154] The pre-configured radio resources refer to information stored on the D2D device before discovery, and the pre-configuration may be configured by the eNB on the network side when the D2D device is under network coverage, or configured by the D2D device manufacturer in advance. The pre-configured wireless resource information includes at least one of the following: frequency, frame / subframe, repetition period (used to indicate the time interval for the D2D device to send / monitor announcement information on the wireless resource), resource index (used to indicate the time interval for different D2D discovers the required wireless resourc...

Abstract

Disclosed are a device-to-device broadcast communication method and a user equipment. The method comprises: performing device-to-device (D2D) broadcast communication outside a coverage area of a network in a centralized manner, and broadcasting data on a shared channel via a centre node; alternatively, performing the device-to-device (D2D) broadcast communication outside the coverage area of the network in a distributed manner, and broadcasting data on a shared channel via resource competition.

Description

technical field [0001] The present invention relates to broadcast communication technology, and in particular to a device-to-device (D2D, Device to Device) broadcast communication method and user equipment. Background technique [0002] In the process of implementing the technical solutions of the embodiments of the present application, the inventors of the present application at least found the following technical problems in the related art: [0003] D2D communication refers to direct communication between adjacent devices, such as Bluetooth. Due to the lack of network control, D2D communication generally uses unlicensed spectrum, such as 2.4GHz. With the rapid popularization of smart phones, many new applications have emerged, such as location-based applications, social applications, and so on. In the mobile communication network, the communication between user equipment must be carried out through the network, such as figure 1 As shown, even if the two devices are loca...
