- 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.
- 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.
- 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.
- 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.
- 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.
- 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 terminal may report capability indication information to the network device, and the capability information is used to indicate the terminal capability.
- 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.
- 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.
- 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.

- 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.
- 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.
- 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.
- other types of direct communication interfaces include direct communication interfaces between terminals and other terminals, or direct communication interfaces between terminals and the second relay, and the second relay is U2U Relay.
- the terminal may choose to determine other types of direct communication interfaces as the target path, or may choose to determine the non-through path as the target path.

本申请要求于2022年09月28日提交的申请号为202211194426.6,发明名称为“数据传输优先级确定方法、装置及设备”的中国专利申请的优先权,其通过引用方式全部并入本文。This application claims priority to Chinese patent application No. 202211194426.6, filed on September 28, 2022, and entitled “Method, device and apparatus for determining data transmission priority”, which is incorporated herein by reference in its entirety.
本公开涉及通信技术领域,尤其涉及一种数据传输优先级确定方法、装置及设备。The present disclosure relates to the field of communication technology, and in particular to a method, device and equipment for determining data transmission priority.
第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)中为了扩展网络覆盖,支持终端通过终端到网络设备中继(UE-to-Network Relay,U2N relay)接入到网络设备。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).
在引入中继后,终端和网络设备通信存在两种传输路径,第一种是直通路径(Direct path),即终端通过无线接口(Uu接口)直接连接到网络设备时使用的传输路径;第二种是非直通路径(Indirect path),即终端通过中继连接到网络设备时使用的传输路径。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.
若终端能力不支持同时在不同传输路径上进行数据传输,当多个不同传输路径都有数据传输需求时,会发生传输冲突。针对终端不同传输路径发生传输冲突的场景,如何确定终端非直通路径对应的直接通信接口(PC5)无线链路控制(Radio Link Control,RLC)承载或PC5 RLC逻辑信道的优先级是一个亟待解决的问题。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.

传统的无线通信采用蜂窝网络通信方式,即终端和网络设备通过Uu接口进行上下行数据/控制信息的传输。例如可以参见图1示例,图1为本公开实施例提供的一种蜂窝网络通信示意图,如图1所示,UE1通过Uu接口接入网络设备,UE2也通过Uu接口接入网络设备。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.
随着通信技术的发展,直接通信技术被提出。直接通信是指邻近的终端可以在近距离范围内通过直接通信链路(也称为Sidelink或者PC5)进行数据传输的方式。直接通信链路对应的无线接口称为直接通信接口(也称为Sidelink接口或者PC5接口)。图2为本公开实施例提供的一种直接通信示意图,如图2所示,UE1通过Uu接口接入网络设备,UE2也通过Uu接口接入网络设备,而UE1和UE2之间通过PC5接口连接。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.
为了扩展网络覆盖,引入了L2中继。图3为本公开实施例提供的一种基于L2中继的通信示意图,如图3所示,终端通过U2N relay(即图3中的中继UE)接入到网络设备,U2N relay可以是一个具有中继功能的终端。对于U2N relay,U2N relay和网络设备之间的接口使用Uu接口,和被中继UE(也称远端UE)之间的接口使用直接通信接口。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.
引入U2N relay后,为了提升远端终端的峰值速率和/或可靠性,引入了会考虑引入多路径传输(multi-path)机制,即终端同时分别通过Uu接口和U2N relay接入网络设备,具体可参见图4。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.
图4为本公开实施例提供的多路径传输示意图,如图4所示,在引入U2N relay后,终端和网络设备通信存在两种传输路径:第一种是直通路径,即终端通过Uu接口直接连接到网络设备使用的传输路径;第二种是非直通路径,即终端通过通过U2N relay连接到网络设备使用的传输路径。终端自身还可能有其他类型的直接通信接口传输路径,例如,终端和终端之间通过直接通信接口进行直接数据传输的传输路径;终端和终端之间通过U2U relay进行数据传输的传输路径。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.
若终端不支持同时在终端和网络设备之间的直通路径和非直通路径传输数据,或者,终端不支持同时在终端和网络设备之间的非直通路径和其
他直接通信接口(比如终端和其他终端之间的直接通信接口或者终端和U2U relay之间的直接通信接口)传输数据,如何确定终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级是一个亟待解决的问题。基于此,本公开实施例提供了一种确定终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级的方法,下面将结合图5对本方案进行介绍。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.
图5为本公开实施例提供的数据传输优先级确定方法的流程示意图,应用于终端,终端通过第一中继接入网络设备,如图5所示,该方法可以包括: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:
步骤51,根据终端和网络设备之间端到端承载相关的优先级,确定终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级。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.
其中,非直通路径是指终端通过第一中继接入网络设备时使用的传输路径,第一中继为U2N Relay。Among them, the non-direct path refers to the transmission path used when the terminal accesses the network device through the first relay, and the first relay is U2N Relay.
本公开实施例中,终端通过第一中继接入网络设备,第一中继为U2N Relay。在该场景下,终端通过Uu接口直接连接到网络设备使用的传输路径为直通路径,终端通过第一中继连接到网络设备使用的传输路径为非直通路径,其中,终端与第一中继之间的接口为PC5接口,第一中继与网络设备之间的接口为Uu接口。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.
非直通路径的直接通信接口传输采用PC5 RLC承载或PC5 RLC逻辑信道,本公开实施例中,可以基于终端和网络设备之间端到端承载相关的优先级,确定终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级。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.
在一些实施例中,网络设备可以向终端发送优先级参数,终端在接收到优先级参数后,即可根据优先级参数确定终端和网络设备之间端到端承载相关的优先级,进而可以根据终端和网络设备之间端到端承载相关的优先级,来确定终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级。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.
在一种可能的实施方式中,优先级参数为QoS参数中的第一优先级参数。网络设备向终端发送端到端承载的全部或部分QoS参数,QoS参数中
包括第一优先级参数。终端在接收到QoS参数后,根据QoS参数中的第一优先级参数,确定终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级。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.
在一种可能的实施方式中,优先级参数为第二优先级参数。网络设备向终端发送第二优先级参数,终端在接收到第二优先级参数后,根据第二优先级参数,确定终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级。其中,第二优先级参数为网络设备针对端到端承载对应的非直通路径上的PC5 RLC承载或PC5 RLC逻辑信道配置的优先级参数。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.
具体的,第二优先级参数可以是网络设备根据Uu接口的QoS参数和逻辑信道优先级参数之间的映射规则确定,该映射规则例如通过指示信息指示第二优先级参数主要用于传输冲突处理。下表1示例了一种第二优先级参数的取值和对应的Uu接口QoS参数中的优先级的对应关系: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:
表1
Table 1
Table 1
除了第二优先级参数外,网络设备还可以为PC5 RLC承载或PC5 RLC逻辑信道配置用于直接通信接口LCP、资源池选择等操作的优先级参数。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.
可选的,网络设备向终端发送指示信息,指示第二优先级参数用于确定非直通路径上PC5 RLC承载或者PC5 RLC逻辑信道进行传输冲突处理时使用的优先级。
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.
在一种可能的实施方式中,若端到端承载为分离类型承载(split类型承载),或者,配置或激活了分组数据汇聚协议重复传输的情况下,网络设备向终端发送第三优先级参数,终端根据第三优先级参数确定终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级。其中,第三优先级参数为网络设备针对端到端承载对应的直通路径上配置的逻辑信道对应的优先级参数。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.
本公开实施例提供的数据传输优先级确定方法,终端通过第一中继接入网络设备,在网络设备向终端发送优先级参数后,终端基于该优先级参数确定终端和网络设备之间端到端承载相关的优先级,进而根据终端和网络设备之间端到端承载相关的优先级,确定终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级,其中,该非直通路径为终端通过第一中继接入网络设备时使用的传输路径。针对终端不支持同时在终端和网络设备之间的直通路径和非直通路径传输数据,或者,终端不支持同时在终端和网络设备之间的非直通路径和其他直接通信接口传输数据的场景,可以基于终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级确定非直通路径的优先级,使得终端能够基于非直通路径的优先级确定传输冲突时刻优先进行数据传输的路径,保证通信系统的正常工作。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.
在上述实施例的基础上,下面结合附图对本公开实施例的方案进行进一步细化。Based on the above embodiments, the scheme of the embodiments of the present disclosure is further refined below in conjunction with the accompanying drawings.
图6为本公开实施例提供的传输冲突解决信令图一,如图6所示,包括:FIG. 6 is a transmission conflict resolution signaling diagram 1 provided in an embodiment of the present disclosure, as shown in FIG. 6 , including:
步骤61,终端向网络设备发送能力指示信息。Step 61: The terminal sends capability indication information to the network device.
图6实施例的方案,示例的是终端不支持在终端和网络设备之间的直通路径和非直通路径对应的直接通信接口同时传输数据的场景下,终端在传输冲突时刻的冲突处理。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.
终端可以向网络设备上报能力指示信息,该能力信息用于指示终端能力,具体的,能力指示信息可以指示终端是否支持在终端和网络设备之间的直通路径和非直通路径同时进行数据传输。若终端支持在终端和网络设
备之间的直通路径和非直通路径同时进行数据传输,则在终端和网络设备之间的直通路径和非直通路径不会产生传输冲突;反之,在终端和网络设备之间的直通路径和非直通路径会产生传输冲突,需要进行传输冲突的处理。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.
能力指示信息也可以指示终端是否支持在不同类型的直接通信接口同时进行数据传输。若终端支持在不同类型的直接通信接口同时进行数据传输,则终端在不同类型的直接通信接口同时传输数据时不会产生传输冲突;反之,在终端在不同类型的直接通信接口同时传输数据时会产生传输冲突,需要进行传输冲突的处理。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.
能力指示信息也可以指示终端支持同时进行数据传输的频带组合。若终端进行数据传输时的频率属于该频带组合,则终端支持同时进行数据传输,不会产生传输冲突;若终端进行数据传输时的频率不属于该频带组合,则终端不支持同时进行数据传输,需要进行传输冲突的处理。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.
需要说明的是,该频带组合,可以仅为针对支持在终端和网络设备之间的直通路径和非直通路径对应的直接通信接口同时传输数据的频带组合,可以仅为支持在非直通路径对应的直接通信接口和其他类型的直接通信接口同时进行数据传输的频带组合,也可以同时包括上述两项,本实施例对此不作限定。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.
步骤62,网络设备向终端发送第一配置信息。Step 62: The network device sends first configuration information to the terminal.
网络设备向终端发送第一配置信息,用于配置非直通路径上的PC5 RLC承载或者PC5 RLC逻辑信道。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.
步骤63,终端进行传输冲突处理。Step 63: The terminal performs transmission conflict processing.
若终端不支持在终端和网络设备之间的直通路径和非直通路径对应的直接通信接口同时传输数据,则在传输冲突时刻,终端确定该直通路径中优先级最高的逻辑信道的第四优先级,并确定非直通路径中优先级最高的PC5 RLC承载或PC5 RLC逻辑信道的第五优先级。然后,终端根据第四优先级和第五优先级,确定传输冲突时刻进行数据传输的目标路径。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.
具体的,在确定第四优先级和第五优先级后,终端可以比较第四优先
级和第五优先级,然后将优先级较高对应的路径确定为传输冲突时刻进行数据传输的目标路径。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.
例如,若优先级的取值越小代表对应的优先级越高,则可以在第四优先级和第五优先级中确定取值更小的优先级,将取值更小的优先级对应的路径确定为传输冲突时刻进行数据传输的目标路径。以第四优先级的取值为1、第五优先级的取值为2为例,第四优先级的取值更小,对应的优先级更高,则可以将第四优先级对应的直通路径确定为目标路径,在传输冲突时刻进行数据传输。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.
在图6实施例中介绍了终端不支持在终端和网络设备之间的直通路径和非直通路径对应的直接通信接口同时传输数据的场景下,终端在传输冲突时刻的冲突处理,下面结合图7介绍终端不支持在非直通路径对应的直接通信接口和其他类型的直接通信接口同时进行数据传输的场景下,终端在传输冲突时刻的冲突处理。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.

终端可以向网络设备上报能力指示信息,该能力信息用于指示终端能力,具体的,能力指示信息可以指示终端是否支持在终端和网络设备之间的直通路径和非直通路径同时进行数据传输。若终端支持在终端和网络设备之间的直通路径和非直通路径同时进行数据传输,则在终端和网络设备之间的直通路径和非直通路径不会产生传输冲突;反之,在终端和网络设备之间的直通路径和非直通路径会产生传输冲突,需要进行传输冲突的处理。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.
能力指示信息也可以指示终端是否支持在不同类型的直接通信接口同时进行数据传输。若终端支持在不同类型的直接通信接口同时进行数据传
输,则终端在不同类型的直接通信接口同时传输数据时不会产生传输冲突;反之,在终端在不同类型的直接通信接口同时传输数据时会产生传输冲突,需要进行传输冲突的处理。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.
能力指示信息也可以指示终端支持同时进行数据传输的频带组合。若终端进行数据传输时的频率属于该频带组合,则终端支持同时进行数据传输,不会产生传输冲突;若终端进行数据传输时的频率不属于该频带组合,则终端不支持同时进行数据传输,需要进行传输冲突的处理。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.
需要说明的是,该频带组合,可以仅为针对支持在终端和网络设备之间的直通路径和非直通路径对应的直接通信接口同时传输数据的频带组合,可以仅为支持在非直通路径对应的直接通信接口和其他类型的直接通信接口同时进行数据传输的频带组合,也可以同时包括上述两项,本实施例对此不作限定。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.
步骤72,网络设备向终端发送第二配置信息。Step 72: The network device sends second configuration information to the terminal.
网络设备向终端发送第二配置信息,用于配置非直通路径上的PC5 RLC承载或者PC5 RLC逻辑信道。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.
步骤73,终端进行传输冲突处理。Step 73: The terminal performs transmission conflict processing.
若终端不支持在非直通路径对应的直接通信接口和其他类型的直接通信接口同时进行数据传输,则在传输冲突时刻,终端确定非直通路径中优先级最高的PC5 RLC承载或PC5 RLC逻辑信道的第五优先级,从而根据第五优先级确定目标路径。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.
具体的,若第五优先级的取值小于或等于第一门限值,则终端将非直通路径确定为传输冲突时刻进行数据传输的目标路径。若第五优先级的取值大于第一门限值,则确定其他类型的直接通信接口中优先级最高的逻辑信道的第六优先级,并根据第六优先级的取值确定目标路径。其中,其他类型的直接通信接口包括终端与其他终端之间的直接通信接口,或终端与第二中继之间的直接通信接口,第二中继为U2U Relay。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. Among them, other types of direct communication interfaces include direct communication interfaces between terminals and other terminals, or direct communication interfaces between terminals and the second relay, and the second relay is U2U Relay.
例如,若第六优先级的取值小于第二门限值,则将其他类型的直接通信接口确定为目标路径;若第六优先级的取值大于第二门限值,则将非直
通路径确定为目标路径;若第六优先级的取值等于第二门限值,则终端可以选择将其他类型的直接通信接口确定为目标路径,也可以选择将非直通路径确定为目标路径。For example, if the value of the sixth priority is less than the second threshold value, other types of direct communication interfaces are determined as the target path; if the value of the sixth priority is greater than the second threshold value, non-direct communication interfaces are determined as the target path. if the value of the sixth priority is equal to the second threshold, the terminal may choose to determine other types of direct communication interfaces as the target path, or may choose to determine the non-through path as the target path.
本公开实施例中,第一门限值可以是网络设备为终端配置的门限值,也可以是预配置的门限值;第二门限值可以是网络设备为终端配置的门限值,也可以是预配置的门限值。In the embodiment of the present disclosure, the first threshold value may be a threshold value configured by the network device for the terminal, or a preconfigured threshold value; the second threshold value may be a threshold value configured by the network device for the terminal, or a preconfigured threshold value.
综上所述,本公开实施例提供了一种数据传输优先级确定方法,终端可以根据终端和网络设备之间端到端承载相关的优先级,确定终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级,从而针对终端不支持在终端和网络设备之间的直通路径和非直通路径对应的直接通信接口同时传输数据的场景,或者,终端不支持在非直通路径对应的直接通信接口和其他类型的直接通信接口同时进行数据传输的场景下,能够在传输冲突时刻基于终端非直通路径对应的PC5 RLC承载或PC5 RLC逻辑信道的优先级确定传输冲突时刻优先进行数据传输的路径,保证通信系统的正常工作。In summary, the embodiments of the present disclosure provide a method for determining data transmission priority, and a terminal can determine the priority of a PC5 RLC bearer or a PC5 RLC logical channel corresponding to a 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 this way, for scenarios 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, or scenarios 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, the method can determine the path for priority data transmission at the moment of transmission conflict based on the priority of the PC5 RLC bearer or the PC5 RLC logical channel corresponding to the non-direct path of the terminal, thereby ensuring the normal operation of the communication system.
