In practical application, the connection between the devices is wireless connection, and in order to conveniently and intuitively represent the connection relationship between the devices, a solid line is used for illustration in fig. 1.
The network device 01 or 02 may be a base station, a core network device, a transmitting/receiving node (Transmission and Reception Point, TRP), a relay station, an access point (e.g., a radio access point (Wireless Access Point, AP)), or the like.

The network device 01 or 02 may also be a node in a 5G communication system or a node in a future evolution network. The words are not to be interpreted as limiting the invention.

When the conventional terminal device and the network device are connected and communicate, a radio frequency communication link (actually, a radio frequency link is shown in a limited way) as shown in fig. 3 is established between the conventional terminal device and the network device. However, with the development of the fifth generation mobile communication (5G), a D2D technology based on a cellular network is proposed, and in order to solve the above problem, in the conventional terminal device, a radio frequency communication circuit for performing D2D communication with other terminal devices is not designed, and in order to add an additional hardware circuit, an embodiment of the present invention proposes multiplexing, for a terminal device having a MIMO circuit, a radio frequency communication circuit for use between the terminal device and a network device when performing D2D communication. For example, when the first terminal device needs to perform service transmission (i.e., D2D communication) with the second terminal device, the terminal device determines at least one antenna from the plurality of antennas for performing service transmission between the first terminal device and the second terminal device. As shown in fig. 4 (a) and fig. 4 (b), two exemplary connection manners between the first terminal device and the network device and the second terminal device are provided in the embodiments of the present invention.
The method, the device and the system for transmitting the service provided by the embodiment of the invention are described in detail by specific embodiments and application scenes thereof by taking the D2D communication between the first terminal device and the second terminal device as an example in the following with reference to the accompanying drawings.
Based on the communication system shown in fig. 1, referring to fig. 5, an embodiment of the present invention provides a service transmission method, which is applied to a first terminal device including N antennas, where the N antennas are used for service transmission with a network device (it should be noted that, the N antennas are antennas used for service transmission with the network device in a conventional terminal, and in the embodiment of the present invention, the N antennas may also be used for service transmission between terminal devices), and the method may include steps 201 to 202 described below.
Step 201, in the case that the first terminal device needs to perform service transmission with the second terminal device, the first terminal device determines a first antenna from the N antennas.
The first antenna is at least one of the N antennas. Wherein N is a positive integer.
It should be noted that in the embodiment of the present invention, any one of the first terminal device and the second terminal device may be an initiator of D2D communication (a device that sends a D2D request message), and the other may be a responder of D2D communication (a device that sends a D2D response message for a D2D request message), which may specifically be determined according to actual use requirements, and embodiments of the present invention are not limited.
The terminal device may trigger the request for the terminal device to perform D2D communication by receiving input such as dialing of a user, application operation (triggering the terminal device to perform D2D connection in an application), and the like.
In the embodiment of the invention, under the condition that the first terminal equipment broadcasts the D2D request message according to the service requirement and the like or transmits the D2D response message of the D2D request message broadcasted by the second terminal equipment, the first terminal equipment determines that the first terminal equipment needs to carry out service transmission with the second terminal equipment, and then the first terminal equipment determines at least one antenna (a first antenna) used for carrying out service transmission between the first terminal equipment and the second terminal equipment from the N antennas.
It may be appreciated that in the embodiment of the present invention, the first antenna has a transmitting function (i.e. at least includes a transmitting module) and a receiving function (i.e. at least includes a receiving module), that is, after the first terminal device establishes a link with the second terminal device, the first terminal device includes at least one transmitting path for the second terminal device and at least one receiving path for the second terminal device, so that service transmission (uploading and/or downloading of services such as data or voice) can be performed between the first terminal device and the second terminal device through the first antenna.
Alternatively, in case the first terminal device knows the traffic volume of the traffic for the second terminal device (hereinafter referred to as first traffic) that needs to be transmitted, the first terminal device may determine the first antenna according to the traffic volume of the first traffic.
This step 201 may be implemented specifically by the following step 201a, for example.
Step 201a, according to the traffic of the first service, the first terminal device determines a first antenna from the N antennas.
Optionally, the first terminal device may determine a traffic volume of the first service according to service information of the first service carried in the D2D request message and/or the D2D response message; the first terminal equipment can also obtain the traffic of the first service from the server; the traffic of the first service may also be obtained through other feasible paths, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited.
For example, when the traffic of the first service is smaller, the first terminal device may determine that fewer antennas are used as the first antennas from the N antennas, as shown in fig. 4 (a), and the first terminal device determines one antenna from the N antennas, and establishes a link with the second terminal device. When the traffic volume of the first service is large, the first terminal device may determine more antennas from the N antennas as the first antennas, as shown in fig. 4 (b), and the first terminal device determines (N-1) antennas from the N antennas, and establishes a link with the second terminal device. The specific determination may be determined according to actual use requirements, and the embodiment of the invention is not limited. For example, the first terminal device may set a first relationship table, where the first relationship table corresponds to the relationship between the value of N, the traffic of the first service, and the number of the first antennas, and the first terminal device may determine the number of the first antennas according to the first relationship table, the traffic of the first service, and the value of N, and further determine the first antennas.
In the embodiment of the invention, the first terminal equipment determines the first antenna according to the traffic of the first service, and further can allocate a corresponding number of antennas according to the traffic, so that the transmission rate and the transmission efficiency of the first service can be improved.
Optionally, in the embodiment of the present invention, before step 201, the first terminal device may have a link connection with the network device, and may also maintain normal communication, and the first terminal device may also have no link connection with the network device.
Optionally, before step 201, the first terminal device may detect the communication quality between the first terminal device and the network device, and if the communication quality is greater than a preset threshold, step 201 is performed, otherwise, not performed. This ensures the communication quality of the link established between the first terminal device and the second terminal device.
Step 202, the first terminal device transmits a first service through a first antenna.
The first service is a service for the second terminal device.
The first terminal device transmits traffic for the second terminal device via the first antenna.
Therefore, in the embodiment of the present invention, on the basis of the antenna design of the conventional terminal device (only N antennas for service transmission between the terminal device and the network device are designed, and no antennas dedicated for service transmission between the terminal device and the terminal device are designed), when the terminal device needs to perform service transmission with other terminal devices, the terminal device may multiplex at least one antenna of the N antennas as an antenna for service transmission with other terminal devices.
The embodiment of the invention provides a service transmission method, wherein under the condition that a first terminal device needs to carry out service transmission with a second terminal device, the first terminal device determines a first antenna from N antennas of the first terminal device; the first traffic is then transmitted through the first antenna. The first service is a service for the second terminal equipment; the first antenna is at least one of the N antennas, and N is a positive integer. In the scheme, under the condition that the first terminal equipment and the second terminal equipment have services to be transmitted, the first terminal equipment determines at least one antenna for transmitting the services to be transmitted from N antennas of the first terminal equipment, namely, the first terminal equipment does not increase antenna design on the basis of traditional antenna design, but multiplexes the antennas in the traditional antenna design to realize supporting data transmission between the terminal equipment and other terminal equipment, so that the complexity of internal layout of the terminal equipment can not be changed.
Optionally, in the case that the first terminal device needs to perform service transmission with the second terminal device, if the first terminal device also needs to perform service transmission with the network device, the first terminal device also needs to determine a second antenna for performing data transmission between the first terminal device and the network device from the N antennas.
It should be noted that, the embodiment of the present invention does not limit the sequence in which the first terminal device needs to perform service transmission with the second terminal device and the first terminal device needs to perform service transmission with the network device. For example, the first terminal device needs to perform service transmission with the second terminal device and the network device at the same time; the first terminal equipment firstly determines that service transmission is required to be carried out with the second terminal equipment, and then determines that service transmission is required to be carried out with the network equipment; the first terminal equipment firstly determines that service transmission is required to be carried out with the network equipment, and then determines that service transmission is required to be carried out with the second terminal equipment.
Optionally, in the embodiment of the present invention, the network device may be a base station or a wireless access point.
In an exemplary case where the first terminal device needs to perform service transmission with both the second terminal device and the network device, as shown in fig. 6, in conjunction with fig. 5, step 201 may be specifically implemented by following step 201b, and after step 202, the service transmission method provided by the embodiment of the present invention may further include the following step 203.
Step 201b, the first terminal device determines a first antenna and a second antenna from the N antennas.
The second antenna is at least one of the other antennas than the first antenna among the N antennas.
The N antennas include a first antenna, a second antenna different from the first antenna, and may further include other antennas than the first antenna and the second antenna.
It will be appreciated that the second antenna also has a transmitting function (i.e. at least comprises a transmitting module) and a receiving function (i.e. at least comprises a receiving module), i.e. after the first terminal device establishes a link with the network device, the first terminal device comprises at least one transmitting path for the network device and at least one receiving path for the network device, so that the first terminal device can perform service transmission (uploading and/or downloading of services such as data or voice) with the network device through the second antenna.
Alternatively, in case the first terminal device knows the traffic volume of the traffic for the network device (hereinafter referred to as second traffic) that needs to be transmitted, the first terminal device may determine the first antenna and the second antenna according to the traffic volume of the first traffic and the traffic volume of the second traffic.
The above step 201b may be specifically implemented by the following step 201 c.
Step 201c, the first terminal device determines the first antenna and the second antenna from the N antennas according to the traffic of the first service and the traffic of the second service.
Optionally, the first terminal device may determine the traffic of the second service according to its own service requirement or the like, or the first terminal device may obtain the traffic of the second service from the network device, or may obtain the traffic of the second service through other feasible paths, which may be specifically determined according to the actual use requirement, and the embodiment of the present invention is not limited.
For example, when the traffic of the second service is less, the first terminal device may determine, as the second antenna, less antennas from the N antennas, and as shown in fig. 4 (b), the first terminal device determines one antenna from the N antennas, and establishes a link with the network device. When the traffic volume of the second service is more, the first terminal device may determine more antennas from the N antennas as the second antennas, as shown in fig. 4 (a), and the first terminal device determines (N-1) antennas from the N antennas, so as to establish a link with the network device. The specific determination may be determined according to actual use requirements, and the embodiment of the invention is not limited. For example, the first terminal device may set a second relation table, where the second relation table corresponds to the relation between the value of N, the traffic of the second service, and the number of second antennas, and the first terminal device may determine the number of second antennas according to the second relation table, the traffic of the second service, and the value of N, and further determine the second antennas.
In the embodiment of the invention, the first terminal equipment determines the second antenna according to the service volume of the second service, so that the corresponding number of antennas can be distributed according to the service volume, and the transmission rate and the transmission efficiency of the second service can be improved.
In the embodiment of the invention, when the first terminal equipment needs to perform service transmission with the second terminal equipment and needs to perform service transmission with the network equipment, the first terminal equipment combines the service volume of the first service and the service volume of the second service, and determines the first antenna and the second antenna from the N antennas. That is, the first terminal device may perform antenna allocation in combination with the traffic of the first service and the traffic of the second service. For example, the first terminal device may uniformly allocate the antennas according to the ratio of the traffic of the first service to the traffic of the second service, or the first terminal device may also set priority (for example, the priority of the video service is higher than the priority of the voice service, the priority of the service between the network device is higher than the priority of the service between the network device and other terminal devices, etc.), and may specifically allocate the antennas according to the priority, which is not limited by the embodiment of the present invention. Thereby, the transmission rate and transmission efficiency of the service can be improved.
It should be noted that, as shown in (b) in fig. 1, in the case where the second terminal device performs data transmission with the network device through the first terminal device, the second service includes the first service, and the number of the first antennas is less than or equal to the number of the second antennas. Therefore, the service transmission between the first terminal device and the second terminal device or the network device can be better realized, and the transmission rate and the transmission efficiency of the service can be improved.
Step 203, the first terminal device transmits the second service through the second antenna.
The second service is a service for the network device.
The first terminal device transmits traffic for the network device via the second antenna.
It should be noted that the embodiment of the present invention is not limited to the execution sequence between the step 202 and the step 203. For example, the first terminal device may perform step 202 described above, and then perform step 203 described above; step 203 may be performed first, and then step 202 may be performed; the above-described steps 202 and 203 may also be performed simultaneously.
In the embodiment of the invention, the first terminal equipment can determine the first antenna and the second antenna from N antennas under the condition that the first terminal equipment needs to carry out service transmission with the second terminal equipment and the network equipment, then transmit the service for the second terminal equipment through the first antenna and transmit the service for the network equipment through the second antenna, thereby realizing the service transmission between the first terminal equipment and the service transmission between the first terminal equipment and the network equipment.
The above-mentioned requirement that the first terminal device performs service transmission with the network device may specifically include the following two possible cases.
In a possible case, when the first terminal device determines that the first terminal device needs to perform service transmission with the network device according to own service requirements and the like under the condition that a link is not established between the first terminal device and the network device, the first terminal device determines at least one antenna (second antenna) from other antennas except the first antenna in the N antennas, and is used for transmitting data between the first terminal device and the network device.
In this case, the embodiment of the present invention does not limit the order in which the first terminal device determines the first antenna and the second antenna. For example, the first terminal device may determine the first antenna first and then determine the second antenna; the first terminal device may determine the second antenna first and then determine the first antenna; the first terminal device may also determine the first antenna and the second antenna simultaneously.
Optionally, in the case that no link exists between each of the first antennas and the network device, the first terminal device needs to first establish a link between the first antenna and the second terminal device before the first terminal device transmits the first service through the first antenna.
For example, in connection with fig. 5, as shown in fig. 7, prior to step 202, an embodiment of the present invention may further include step 204 described below.
Step 204, the first terminal device establishes a link between the first antenna and the second terminal device.
The specific link establishment process may refer to any related technology, and embodiments of the present invention are not limited.
The first terminal device transmits the first service through the established link between the first antenna and the second terminal device.
The first terminal device establishes a link between the second antenna and the network device. The specific link establishment process may refer to any related technology, and embodiments of the present invention are not limited. And the first terminal equipment transmits the second service through the established link between the second antenna and the network equipment.
In the embodiment of the invention, after the link is established, the first terminal equipment can transmit the first service with the second terminal equipment through the link between the first antenna and the second terminal equipment, and the first terminal equipment can transmit the second service with the network equipment through the link between the second antenna and the network equipment.
In another possible scenario, in a case where the first terminal device has established a link with the network device, and in a case where there is a target link between the third antenna (at least one antenna) in the first antenna and the network device, before the first terminal device transmits the first service through the first antenna, the first terminal device needs to release the target link first, and then establish a link between the first antenna and the network device.
For example, in connection with fig. 5, as shown in fig. 8, prior to step 202, embodiments of the present invention may further include steps 205-206 described below.
Step 205, in case that a target link is established between the third antenna and the network device, the first terminal device releases the target link.
In step 201, the third antenna is determined as the antenna for transmitting the service between the first terminal device and the second terminal device, so that the third antenna needs to establish a link with the second terminal device, and then the third antenna needs to disconnect from the network device, i.e. the first terminal device needs to release the target link established between the third antenna and the network device, and the process of releasing the link can refer to any related technology, which is not described herein.
Step 206, the first terminal device establishes a link between the first antenna and the second terminal device.
In the case that the first antenna does not establish a link with the network device or other terminal devices, the first terminal device establishes a link between the first antenna and the second terminal device, and the link establishment process may refer to any relevant technology, which is not described herein.
It should be noted that, similarly, in the case that no link exists between each antenna in the second antenna and other terminal devices, before the first terminal device transmits the second service through the second antenna, the first terminal device needs to first establish a link between the second antenna and the network device. If the first terminal device has established a link with another terminal device, and if there is a link 1 between the fourth antenna (at least one antenna) in the second antenna and the other terminal device, before the first terminal device transmits the second service through the second antenna, the first terminal device needs to release the link 1 first, and then establish a link between the second antenna and the network device. Reference is made specifically to the above related descriptions, and no further description is given here.
In the embodiment of the invention, after the first antenna is determined, the terminal equipment adjusts the link between the first terminal equipment and the second terminal equipment and the link between the first terminal equipment and the network equipment according to the actual situation, and then realizes the service transmission between the first terminal equipment and the second terminal equipment and between the first terminal equipment and the network equipment.
