Embodiment 1

[0064] Figure 5 Shown is a schematic diagram based on the implementation 1 of the wireless communication method of the present invention, and the embodiment 1 includes the following steps:

[0065] Step 501: the relay user equipment first requests resources from the network equipment, and the requested resources are used for the transmission of related signals / signaling or data when discovering each other with the source user equipment;

[0066] The process of requesting resources may also include the process of the relay user equipment registering (Registration) and / or authentication (Authentication) and / or attaching (Attach) to the network; and RRC (Radio Resource Control, radio resource control) on the wireless side The process of establishing a connection. Through the resource request, the relay user equipment obtains authorization to discover each other with other source user equipment from the network side. For example, after the relay function of the relay user equipme...

Embodiment 2

[0097] Figure 6 Shown is a schematic diagram of another embodiment based on the solution of the present invention. In this example include:

[0098] Step 601: When the user equipment judges that the dedicated cellular communication condition is satisfied, send a dedicated discovery signal, and relay the user equipment to detect the dedicated discovery signal;

[0099] When the relay function of the relay user equipment is activated or turned on, a dedicated discovery signal is detected in the dedicated resource; the dedicated discovery signal is used to indicate the existence of the source user equipment or the dedicated cellular communication requirement of the source user equipment. as mentioned earlier.

[0100] Step 602: After detecting the dedicated discovery signal sent by the source user equipment, the relay user equipment requests resources from the network equipment, and the requested resources are used for mutual discovery and / or communication with the source user...

Embodiment 3

[0107] Figure 7 Shown is a schematic diagram based on Embodiment 3 of the wireless communication method of the present invention, which embodiment includes:

[0108] Step 701: When the user equipment judges that the dedicated cellular communication condition is satisfied, send a dedicated discovery signal, and relay the user equipment to detect the dedicated discovery signal;

[0109] When the relay function of the relay user equipment is activated or turned on, a dedicated discovery signal is detected in the dedicated resource. The dedicated discovery signal is used to indicate the existence of the source user equipment or a dedicated cellular communication requirement of the source user equipment. as mentioned earlier.

[0110] Step 702: After detecting the dedicated discovery signal sent by the source user equipment, the relay user equipment sends a response message, and the source user equipment detects the response message;

[0111] After sending the dedicated discove...

Abstract

The present invention relates to a wireless communications method, user equipment, network device, and system. The method comprises: a first user equipment sending a dedicated discovery signal; the first user equipment receiving a response message, the response message being sent by a second user equipment that detects the dedicated discovery signal; the first user equipment establishing a device-to-device connection with the second user equipment; and the first user equipment communicating with a network side through the device-to-device connection and a communication link between the second user equipment and the network side.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a communication method, user equipment, network equipment and system applied to a cellular wireless communication system. Background technique [0002] Due to the realization of the multiplexing of limited spectrum resources in cellular communication, the wireless communication technology has been developed vigorously. In a cellular communication system, when there is service transmission between two user equipments (UE for short), for example, service data from user equipment 1 (UE1) to user equipment 2 (UE2) will first be transmitted to The base station (Base Station, Node B, evolved Node B) of the cell where UE1 is located transmits the user data to the base station of the cell where UE2 is located through the core network, and then the base station transmits the above service data to UE2 through the air interface. The service data transmission from UE2 to UE1 ad...
