So that the manner in which the features and technical contents of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the present invention will be rendered by reference to the appended drawings, which are included for purposes of illustration and not limitation.
Before describing embodiments of the present invention in detail, a brief description of direct communication is first provided.
Two data transmission modes, mode a and mode B, are defined in the third Generation Partnership Project (3 GPP).
For mode a, the flow of data transmission, as shown in fig. 1, the transmission resource of the terminal device is allocated by the base station, and the terminal device transmits data on the sidelink according to the resource allocated by the base station; the base station may allocate resources for single transmission to the terminal device, or may allocate resources for semi-static transmission to the terminal device.
For the mode B, the data transmission process, as shown in fig. 2, the terminal device obtains an available transmission resource set in the resource pool by means of listening, and the terminal device randomly selects a resource from the set to perform the transmission of the sidelink data.
In Rel-12/13, device-to-device communication is studied for ProSe scenarios, especially for public safety class traffic. Wherein, the discontinuous receiving and sending parameters are configured or pre-configured by the network equipment. Based on the network device or the terminal device propagating the timing reference signal, data transmission and reception between the terminal devices can be realized only if the terminal devices communicating with each other are configured with the same discontinuous transmission and reception parameter configuration, that is, the terminal devices have the same cognition for the discontinuous transmission and reception parameter configuration based on the pre-configuration of heartache or the configuration of the network device.
In Rel-14/15, the car networking system is studied for communication scenarios between vehicles, especially for the traffic of car-to-car, car-to-person communication moving at relatively high speed. In the environment of the Internet of vehicles, the terminal equipment of the automobile has fixed power supply input, so that discontinuous receiving and sending parameters are not configured; i.e. assuming that the car class terminal device is always in a state of continuous reception. The handheld terminal equipment does not have fixed power income, and discontinuous reception needs to be considered from the working principle; however, discontinuous reception is contrary to the low latency requirements of the vehicle network; therefore, the handheld terminal device in the car networking environment does not realize the data receiving function, but is in a one-way sending state; namely, the data is transmitted in one way by means of the receiving function of the automobile terminal equipment.
In Rel-14, a scene that a wearable device accesses a network through a mobile phone is studied, and particularly, the scene facing low moving speed and low power access is studied. In the scene of the wearable device, the mode of discontinuous data transceiving used in the communication between the wearable device and the mobile phone is researched; the use mode is as follows: and the base station configures discontinuous receiving and sending parameters of the remote terminal equipment through the relay terminal equipment. And after receiving the discontinuous receiving and sending parameters configured by the base station, the remote terminal equipment communicates with the relay terminal equipment based on the discontinuous receiving and sending parameters.
Therefore, in the related art, the car networking system does not optimize discontinuous transceiving. Although the ProSe scenario and the wearable device scenario are optimized for discontinuous transmission and reception, the following problems exist:
when a plurality of terminal devices want to access the same terminal device at the same time, or one terminal device wants to access a plurality of terminal devices, resource differentiation can not be carried out for different access devices or accessed devices; that is, a plurality of access devices or accessed devices use the same resource to communicate at the same time, thereby causing resource conflict and reducing the access success rate.
When the resources conflict, the terminal device decides the sending or receiving direction (in the related art, sending data is prior to receiving data); thus, when the first terminal device sends data to the second terminal device, the second terminal device is sending data to the third terminal device; i.e. collisions in duplex mode. Therefore, not only can the access request sent by the first terminal device not be received, but also the first terminal device needs to send the access request for multiple times until the second terminal device is in a receiving state; not only is the transmission power and transmission resources of the first terminal device wasted, but also the access success rate is reduced.
Based on the above problem, the present invention provides a data transmission method, and the data transmission method according to the embodiment of the present application may be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, or a 5G System.

As shown in fig. 4, an optional processing flow of the data transmission method provided in the embodiment of the present invention includes the following steps:
step S201, a first terminal device determines a first resource based on first indication information, where the first resource is used for data transmission between the first terminal device and at least one second terminal device.
In some embodiments, the first indication information comprises: an identity of the first terminal device. The identity of the first terminal device comprises at least one of: the user identifier of the first terminal device, at least one first communication group identifier to which the first terminal device belongs, an identifier of at least one first communication service supported by the first terminal device, and address information of the first terminal device. The identification of the first terminal device comprises: a higher layer identification and/or an access layer identification. Wherein the address information of the first terminal device comprises at least one of: address information of an access layer, address information of a layer 2; the address information of the first terminal device includes: a source address and/or a destination address.
For example, Y time resources are configured in a specific time period, and a first resource is selected from the Y time resources for data transmission, where the Y time resources may be discontinuous. If the first indication information includes that the identifier of the first terminal device is X, a modulo of the identifier of the first terminal device, that is, mod (X, Y), may be obtained, and a result of the modulo is the first resource used for data transmission. Because different terminal devices, communication groups to which the different terminal devices belong, and communication services supported by the different terminal devices all have different identifiers, results obtained by modulo the identifiers corresponding to the different first terminal devices are different, that is, resources used by the terminal devices corresponding to the different identifiers during data transmission are different, which is beneficial to balancing access signaling load in a network.
In the above embodiment, the identifier of the first terminal device is used as a reference factor for determining the first resource. In specific implementation, the identifier of the first terminal device may not be used as a reference factor for determining the first resource; i.e. Y time resources may be used in common by different user equipments, or different communication groups, or different communication services.
Whether or not the identity of the first terminal device is taken as a reference factor for determining the first resource, the first terminal device may determine the first resource based on the discontinuous parameter configuration for the resource; the discontinuous parameter configuration comprises: a periodic configuration of non-contiguous resources, and/or a timer duration. The first terminal device determines a schematic diagram of the first resource, as shown in fig. 5.
In still other embodiments, the first indication information includes: an identity of the second terminal device. The identity of the second terminal device comprises at least one of: the user identifier of the second terminal device, at least one second communication group identifier to which the second terminal device belongs, an identifier of at least one second communication service supported by the second terminal device, and address information of the second terminal device. The identification of the second terminal device comprises: a higher layer identification and/or an access layer identification. Wherein the address information of the second terminal device comprises at least one of: address information of an access layer, address information of a layer 2; the address information of the second terminal device includes: a source address and/or a destination address.
In specific implementation, the data transmission between the first terminal device and at least one second terminal device is as follows: when the first terminal equipment establishes connection with at least one second terminal equipment, the first terminal equipment receives a first message sent by the at least one second terminal equipment. The first message is used for the first terminal device to establish connection with the at least one second terminal device. Optionally, the first message is an access request message, and the second terminal device requests to establish a connection with the first terminal device based on the access request message. Before the second terminal device sends the first message to the first terminal device, the second terminal device may determine, based on the identifier of the first terminal device in the first indication information, a first resource, where the first resource is a resource used for sending the first message and for data transmission between the first terminal device and the second terminal device. Optionally, before the second terminal device sends the first message, the second terminal device listens for a second message sent by the first terminal device on the first resource, where the second message is used for the first terminal device to notify the relevant access parameter. Optionally, the second message is an access broadcast message. Optionally, the access broadcast message is used to notify that the access request message can be received by the access broadcast message, or to notify that the access broadcast message can establish a connection with other terminal devices; and after the second terminal equipment senses the second message, the second terminal equipment sends the first message to the first terminal equipment.
Or, as shown in fig. 6, after determining the first resource based on the identifier of the first terminal device, the second terminal device sends a first message to the first terminal device on the first resource to request to establish a connection with the first terminal device; optionally, the first resource is N time resources. And then, before the second terminal equipment sends the data to the first terminal equipment, determining resources for sending the data according to the identifier of the second terminal equipment in the first indication information. For example, the first resource is N time resources, and the second resource is selected from the N time resources for data transmission, where the N time resources may be non-consecutive. The identifier of the second terminal device is N, and a modulo result of the identifier of the second terminal device, that is, mod (Z, N), is the second resource used for data transmission.
In the embodiment of the present invention, because different terminal devices, communication groups to which different terminal devices belong, and communication services supported by different terminal devices all have different identifiers, results obtained by modulo different identifiers corresponding to different second terminal devices are also different, that is, resources used when data transmission is performed by terminal devices corresponding to different identifiers are different, and different second terminal devices send access request messages at different time resources, which is beneficial to balancing access signaling loads in a network.
In the above embodiment, the identifier of the second terminal device is used as a reference factor for determining the second resource. In specific implementation, the identifier of the second terminal device may not be used as a reference factor for determining the first resource; the N time resources may be commonly used by different user equipments, or different communication groups, or different communication services. That is, different second terminal devices select one time resource from available time resources to send the first message to the first terminal device.
It should be noted that, after the first terminal device establishes a connection with the second terminal device, the first terminal device may perform data transmission with the second terminal device; when a first terminal device needs to send data to a second terminal device, the first terminal device needs to determine whether a resource used for sending the data conflicts with a resource used for receiving the data by the first terminal device, or whether a resource used for sending the data by the first terminal device conflicts with a subset of the resource used for receiving the data by the first terminal device. When the judgment result is a conflict, the method further comprises the following steps:
and the first terminal equipment determines to preferentially transmit data or preferentially receive data based on the second indication information. Wherein the second indication information comprises at least one of: quality of Service (QoS) attributes of the data and configuration from the network device. Taking the example that the second indication information includes the QoS attribute of the data, when the QoS attribute satisfies the preset condition, the data transmission is preferentially performed, or when the QoS attribute satisfies the preset condition, the data reception is preferentially performed. Taking the QoS attribute as a QoS Class Identifier (QCI) as an example, if the QoS related value is greater than or less than a preset QoS related value threshold value, data transmission is preferentially performed; the data transmission is unicast transmission, or multicast transmission, or broadcast transmission. And taking the second indication information as an example of the configuration from the network device, when the network device configures the relevant parameters to indicate that data reception is to be performed preferentially, and when the resource used by the first terminal device for transmitting the data conflicts with the resource used by the first terminal device for receiving the data, the first terminal device performs data reception preferentially. In the embodiment of the present invention, as shown in fig. 7, the resource used for data reception and the resource used for data transmission are independent from each other, so that when the first terminal device is performing data transmission, the second terminal device may also transmit an access request to the first terminal device.
It should be noted that, in this embodiment of the present invention, the data transmission between the first terminal device and at least one second terminal device includes: and the first terminal equipment transmits data to the at least one second terminal equipment, or receives data from the at least one second terminal equipment. Optionally, the data is sidelink data.
Based on the foregoing embodiment, as shown in fig. 8, in an optional schematic diagram of data transmission performed between a first terminal device and a second terminal device in the embodiment of the present invention, after the first terminal device determines a first resource for receiving data according to discontinuous parameter configuration, the second terminal device calculates a time domain resource or a frequency domain resource for performing data transmission with the first terminal device, and sends an access request message to the first terminal device to establish a connection; then, the first terminal device determines whether to prioritize data reception. Or, as shown in fig. 9, after the first terminal device determines resources for data reception and/or data transmission according to the discontinuous parameter configuration, the second terminal device calculates time domain resources and/or frequency domain resources for the first terminal device to transmit data; the second terminal equipment receives the sidelink discovery message sent by the first terminal equipment on the time domain resource and/or the frequency domain resource obtained by calculation, and calculates the time domain resource or the frequency domain resource of the first terminal equipment for data sending; sending an access request message to a first terminal device to establish a connection; then, the first terminal device determines to perform data transmission or data reception preferentially.
In the embodiment of the invention, after determining a first resource for data reception, a first terminal device only turns on a receiver at a time position corresponding to the first resource; other time locations than the first resource turn off the receiver. After determining a first resource for data transmission, the first terminal device opens a transmitter only at a time position corresponding to the first resource; the transmitter is turned off at a time location other than the first resource. Thus, the electric quantity can be saved.
An embodiment of the present invention further provides a first terminal device, where a schematic structural diagram of the first terminal device 300 is shown in fig. 10, and the first terminal device includes:
