AI Technical Summary

Problems solved by technology

If the user device is not within the signal coverage of the base station, it cannot obtain resource allocation and thus cannot communicate with other user devices
In addition, the existing 3GPP LTE network does not provide direct communication services between user devices, so the existing 3GPP LTE network user devices cannot be used in public safety networks

Abstract

A device to device (D2D) user equipment and a base station are provided. The D2D user equipment includes a transceiver and a processor. The transceiver receives a wireless signal having a hybrid access channel carrying a D2D hybrid access map. The processor is electrically connected to the transceiver and retrieves the D2D hybrid access map from the hybrid access channel. The D2D hybrid access map indicates a D2D resource block. A first D2D user equipment transmits a D2D hybrid access request to a second D2D user equipment via the D2D resource block and the second D2D user equipment transmits a D2D hybrid access response to the first D2D user equipment via the D2D resource block. Accordingly, the first D2D user equipment and the second D2D user equipment perform D2D data transmission according to the D2D data transmission information carried in the D2D hybrid access response.

Description

technical field [0001] The present invention relates to a device to device (D2D) user device and a base station. More specifically, the base station of the present invention generates a device-to-device (D2D) hybrid access map, which includes information on resource block allocation required for data transmission between D2D user devices, so that the D2D user devices can use The allocated resource blocks are used for D2D data transmission. Background technique [0002] In recent years, with the maturity of wireless communication technology, many wireless network systems are derived and used in various occasions. Under the framework of the public safety network, in order to provide emergency communication services (such as calling the police, fire station or ambulance) or communication services between groups, there is a need for direct communication between adjacent user devices, so that Communication with each other is more efficient. However, these direct communication ...
