CROSS-REFERENCE TO RELATED APPLICATIONS

Background technique

In order to expand network coverage, the 3rd Generation Partnership Project (3GPP) supports terminals to access network devices through terminal-to-network device relay (UE-to-Network Relay, U2N relay).

After the introduction of relays, there are two transmission paths for communication between terminals and network devices. The first is the direct path, which is the transmission path used when the terminal is directly connected to the network device through the wireless interface (Uu interface); the second is the indirect path, which is the transmission path used when the terminal is connected to the network device through a relay.

If the terminal capability does not support data transmission on different transmission paths at the same time, when multiple different transmission paths have data transmission requirements, transmission conflicts will occur. In the scenario where transmission conflicts occur on different transmission paths of the terminal, how to determine the priority of the direct communication interface (PC5) radio link control (Radio Link Control, RLC) bearer or PC5 RLC logical channel corresponding to the terminal's non-through path is an urgent problem to be solved.

Detailed ways

Traditional wireless communication uses a cellular network communication mode, that is, the terminal and the network device transmit uplink and downlink data/control information through the Uu interface. For example, see Figure 1, which is a schematic diagram of a cellular network communication provided by an embodiment of the present disclosure. As shown in Figure 1, UE1 accesses the network device through the Uu interface, and UE2 also accesses the network device through the Uu interface.

With the development of communication technology, direct communication technology has been proposed. Direct communication refers to a method in which adjacent terminals can transmit data through a direct communication link (also called Sidelink or PC5) within a short range. The wireless interface corresponding to the direct communication link is called a direct communication interface (also called Sidelink interface or PC5 interface). Figure 2 is a schematic diagram of direct communication provided by an embodiment of the present disclosure. As shown in Figure 2, UE1 accesses the network device through the Uu interface, UE2 also accesses the network device through the Uu interface, and UE1 and UE2 are connected through the PC5 interface.

In order to expand network coverage, L2 relay is introduced. FIG3 is a schematic diagram of a communication based on L2 relay provided by an embodiment of the present disclosure. As shown in FIG3 , a terminal accesses a network device through a U2N relay (i.e., a relay UE in FIG3 ). The U2N relay can be a terminal with a relay function. For the U2N relay, the interface between the U2N relay and the network device uses a Uu interface, and the interface between the U2N relay and the relayed UE (also called the remote UE) uses a direct communication interface.

After the introduction of U2N relay, in order to improve the peak rate and/or reliability of the remote terminal, a multi-path transmission (multi-path) mechanism is considered to be introduced, that is, the terminal simultaneously accesses the network device through the Uu interface and U2N relay respectively. For details, please see Figure 4.

FIG4 is a schematic diagram of multi-path transmission provided by an embodiment of the present disclosure. As shown in FIG4, after the introduction of U2N relay, there are two transmission paths for communication between the terminal and the network device: the first is a direct path, that is, the terminal is directly connected to the network device through the Uu interface. The second is a non-direct path, that is, the terminal is connected to the network device through the U2N relay. The terminal itself may also have other types of direct communication interface transmission paths, for example, a transmission path for direct data transmission between terminals through a direct communication interface; a transmission path for data transmission between terminals through U2U relay.

If the terminal does not support data transmission on both direct and indirect paths between the terminal and the network device, or the terminal does not support data transmission on both indirect paths between the terminal and the network device, How to determine the priority of the PC5 RLC bearer or PC5 RLC logical channel corresponding to the non-through path of the terminal is an urgent problem to be solved. Based on this, the embodiment of the present disclosure provides a method for determining the priority of the PC5 RLC bearer or PC5 RLC logical channel corresponding to the non-through path of the terminal, and the scheme will be introduced in conjunction with Figure 5 below.

FIG5 is a flow chart of a method for determining a data transmission priority provided by an embodiment of the present disclosure, which is applied to a terminal. The terminal accesses a network device through a first relay. As shown in FIG5 , the method may include:

Step 51, based on the priority related to the end-to-end bearer between the terminal and the network device, determine the priority of the PC5 RLC bearer or PC5 RLC logical channel corresponding to the non-through path of the terminal.

In the disclosed embodiment, the terminal accesses the network device through the first relay, and the first relay is U2N Relay. In this scenario, the transmission path used by the terminal directly connected to the network device through the Uu interface is a straight-through path, and the transmission path used by the terminal connected to the network device through the first relay is a non-straight-through path, wherein the interface between the terminal and the first relay is a PC5 interface, and the interface between the first relay and the network device is a Uu interface.

The direct communication interface transmission of the non-direct path adopts PC5 RLC bearer or PC5 RLC logical channel. In the embodiment of the present disclosure, the priority of the PC5 RLC bearer or PC5 RLC logical channel corresponding to the non-direct path of the terminal can be determined based on the priority related to the end-to-end bearer between the terminal and the network device.

In some embodiments, the network device can send a priority parameter to the terminal. After receiving the priority parameter, the terminal can determine the priority related to the end-to-end bearer between the terminal and the network device according to the priority parameter, and then determine the priority of the PC5 RLC bearer or PC5 RLC logical channel corresponding to the non-direct path of the terminal according to the priority related to the end-to-end bearer between the terminal and the network device.

In a possible implementation, the priority parameter is the first priority parameter in the QoS parameters. The network device sends all or part of the QoS parameters of the end-to-end bearer to the terminal. Including the first priority parameter. After receiving the QoS parameters, the terminal determines the priority of the PC5 RLC bearer or PC5 RLC logical channel corresponding to the non-through path of the terminal according to the first priority parameter in the QoS parameters.

In a possible implementation, the priority parameter is a second priority parameter. The network device sends the second priority parameter to the terminal, and after receiving the second priority parameter, the terminal determines the priority of the PC5 RLC bearer or PC5 RLC logical channel corresponding to the non-through path of the terminal according to the second priority parameter. The second priority parameter is a priority parameter configured by the network device for the PC5 RLC bearer or PC5 RLC logical channel on the non-through path corresponding to the end-to-end bearer.

Specifically, the second priority parameter can be determined by the network device according to the mapping rule between the QoS parameter of the Uu interface and the logical channel priority parameter, and the mapping rule indicates, for example, through the indication information, that the second priority parameter is mainly used for transmission conflict processing. The following Table 1 illustrates a corresponding relationship between the value of the second priority parameter and the priority in the corresponding Uu interface QoS parameter:

Table 1

In addition to the second priority parameters, the network device can also configure priority parameters for PC5 RLC bearers or PC5 RLC logical channels for operations such as direct communication interface LCP, resource pool selection, etc.

Optionally, the network device sends indication information to the terminal, indicating that the second priority parameter is used to determine the priority used when the PC5 RLC bearer or PC5 RLC logical channel on the non-through path performs transmission conflict processing.

In a possible implementation, if the end-to-end bearer is a split type bearer (split type bearer), or when the packet data convergence protocol repeated transmission is configured or activated, the network device sends a third priority parameter to the terminal, and the terminal determines the priority of the PC5 RLC bearer or PC5 RLC logical channel corresponding to the non-through path of the terminal according to the third priority parameter. The third priority parameter is a priority parameter corresponding to the logical channel configured by the network device on the through path corresponding to the end-to-end bearer.

The method for determining data transmission priority provided by the embodiment of the present disclosure is that a terminal accesses a network device through a first relay, and after the network device sends a priority parameter to the terminal, the terminal determines the priority of the end-to-end bearer between the terminal and the network device based on the priority parameter, and then determines the priority of the PC5 RLC bearer or PC5 RLC logical channel corresponding to the non-direct path of the terminal according to the priority of the end-to-end bearer between the terminal and the network device, wherein the non-direct path is the transmission path used when the terminal accesses the network device through the first relay. For scenarios where the terminal does not support simultaneous transmission of data through a direct path and a non-direct path between the terminal and the network device, or the terminal does not support simultaneous transmission of data through a non-direct path and other direct communication interfaces between the terminal and the network device, the priority of the non-direct path can be determined based on the priority of the PC5 RLC bearer or PC5 RLC logical channel corresponding to the non-direct path of the terminal, so that the terminal can determine the path for priority data transmission at the moment of transmission conflict based on the priority of the non-direct path, thereby ensuring the normal operation of the communication system.

Based on the above embodiments, the scheme of the embodiments of the present disclosure is further refined below in conjunction with the accompanying drawings.

FIG. 6 is a transmission conflict resolution signaling diagram 1 provided in an embodiment of the present disclosure, as shown in FIG. 6 , including:

Step 61: The terminal sends capability indication information to the network device.

The solution of the embodiment of FIG. 6 illustrates the conflict handling of the terminal at the moment of transmission conflict in a scenario where the terminal does not support simultaneous data transmission on the direct communication interface corresponding to the direct path and the non-direct path between the terminal and the network device.

The terminal can report capability indication information to the network device. The capability information is used to indicate the terminal capability. Specifically, the capability indication information can indicate whether the terminal supports simultaneous data transmission on a direct path and a non-direct path between the terminal and the network device. If the direct path and the indirect path between the devices perform data transmission at the same time, the direct path and the indirect path between the terminal and the network device will not cause transmission conflicts; on the contrary, the direct path and the indirect path between the terminal and the network device will cause transmission conflicts, which need to be handled.

The capability indication information may also indicate whether the terminal supports simultaneous data transmission on different types of direct communication interfaces. If the terminal supports simultaneous data transmission on different types of direct communication interfaces, no transmission conflict will occur when the terminal transmits data on different types of direct communication interfaces at the same time; otherwise, a transmission conflict will occur when the terminal transmits data on different types of direct communication interfaces at the same time, and the transmission conflict needs to be handled.

The capability indication information may also indicate the frequency band combination that the terminal supports for simultaneous data transmission. If the frequency at which the terminal performs data transmission belongs to the frequency band combination, the terminal supports simultaneous data transmission and no transmission conflict will occur; if the frequency at which the terminal performs data transmission does not belong to the frequency band combination, the terminal does not support simultaneous data transmission and needs to handle transmission conflicts.

It should be noted that the frequency band combination may be only a frequency band combination for supporting simultaneous data transmission between the direct communication interface corresponding to the direct path and the non-direct path between the terminal and the network device, may be only a frequency band combination for supporting simultaneous data transmission between the direct communication interface corresponding to the non-direct path and other types of direct communication interfaces, or may include both of the above, which is not limited in this embodiment.

Step 62: The network device sends first configuration information to the terminal.

The network device sends first configuration information to the terminal, which is used to configure a PC5 RLC bearer or a PC5 RLC logical channel on a non-through path.

Step 63: The terminal performs transmission conflict processing.

If the terminal does not support simultaneous data transmission on the direct communication interface corresponding to the direct path and the non-direct path between the terminal and the network device, then at the moment of transmission conflict, the terminal determines the fourth priority of the logical channel with the highest priority in the direct path, and determines the fifth priority of the PC5 RLC bearer or PC5 RLC logical channel with the highest priority in the non-direct path. Then, the terminal determines the target path for data transmission at the moment of transmission conflict based on the fourth priority and the fifth priority.

Specifically, after determining the fourth priority and the fifth priority, the terminal may compare the fourth priority The first and fifth priorities are determined, and then the path corresponding to the higher priority is determined as the target path for data transmission at the time of transmission conflict.

For example, if the smaller the value of the priority is, the higher the corresponding priority is, then the smaller priority can be determined between the fourth priority and the fifth priority, and the path corresponding to the smaller priority can be determined as the target path for data transmission at the time of transmission conflict. Taking the fourth priority value as 1 and the fifth priority value as 2 as an example, the fourth priority value is smaller and the corresponding priority is higher, then the direct path corresponding to the fourth priority can be determined as the target path, and data transmission can be performed at the time of transmission conflict.

The embodiment of Figure 6 introduces the conflict handling of the terminal at the moment of transmission conflict in a scenario where the terminal does not support simultaneous data transmission between the direct path and the direct communication interface corresponding to the non-direct path between the terminal and the network device. The following, combined with Figure 7, introduces the conflict handling of the terminal at the moment of transmission conflict in a scenario where the terminal does not support simultaneous data transmission between the direct communication interface corresponding to the non-direct path and other types of direct communication interfaces.

FIG. 7 is a second transmission conflict resolution signaling diagram provided by an embodiment of the present disclosure. As shown in FIG. 7 , the signaling diagram includes:

Step 71: The terminal sends capability indication information to the network device.

The solution of the embodiment of FIG. 7 illustrates the conflict handling of the terminal at the transmission conflict moment when the terminal does not support simultaneous data transmission on the direct communication interface corresponding to the non-through path and other types of direct communication interfaces.

The terminal may report capability indication information to the network device, and the capability information is used to indicate the terminal capability. Specifically, the capability indication information may indicate whether the terminal supports simultaneous data transmission on a direct path and a non-direct path between the terminal and the network device. If the terminal supports simultaneous data transmission on a direct path and a non-direct path between the terminal and the network device, the direct path and the non-direct path between the terminal and the network device will not generate a transmission conflict; otherwise, the direct path and the non-direct path between the terminal and the network device will generate a transmission conflict, and the transmission conflict needs to be handled.

The capability indication information may also indicate whether the terminal supports simultaneous data transmission on different types of direct communication interfaces. If the terminal transmits data through different types of direct communication interfaces at the same time, no transmission conflict will occur; otherwise, a transmission conflict will occur when the terminal transmits data through different types of direct communication interfaces at the same time, and the transmission conflict needs to be handled.

Step 72: The network device sends second configuration information to the terminal.

The network device sends second configuration information to the terminal, which is used to configure the PC5 RLC bearer or PC5 RLC logical channel on the non-through path.

Step 73: The terminal performs transmission conflict processing.

If the terminal does not support simultaneous data transmission on the direct communication interface corresponding to the non-through path and other types of direct communication interfaces, then at the moment of transmission conflict, the terminal determines the fifth priority of the PC5 RLC bearer or PC5 RLC logical channel with the highest priority in the non-through path, and determines the target path according to the fifth priority.

Specifically, if the value of the fifth priority is less than or equal to the first threshold value, the terminal determines the non-through path as the target path for data transmission at the time of transmission conflict. If the value of the fifth priority is greater than the first threshold value, the sixth priority of the logical channel with the highest priority in other types of direct communication interfaces is determined, and the target path is determined according to the value of the sixth priority.
