- the PDCP entity of the remote device can stop sending data to the relay device corresponding to the indirect path. If the indirect path is deactivated and no longer transmits data, the PDCP entity may stop sending data to the relay device corresponding to the indirect path. In addition, before the indirect path is deactivated, the PDCP entity may have sent data to the relay device corresponding to the indirect path, and these data may not be able to reach the remote device because the indirect path is deactivated. end device, which may cause packet loss.

- the first deactivation command can also set the transmission path (such as a direct path) of the remote device that has not been deactivated as the primary path (primary path), and can set the threshold (threshold) to infinity. This prevents the PDCP entity from transmitting data to the relay device corresponding to the indirect path.
- the threshold can be used by the remote device to select a transmission path.
- the data can only be sent on the primary path; or if the amount of data to be sent by the remote device is greater than the threshold, the data can be sent on the primary path and/or the secondary path.

Then the remote device can be controlled to only send data on the main path and no longer Data is sent using an indirect path (secondary path) that has been deactivated.
- the first deactivation command is an RRC command, and for example, the RRC command is an RRC reconfiguration (RRC reconfiguration) message.
- the first deactivation command may also be a message of other types, with no specific limitation.
- the behavior of the PDCP entity may not be explicitly triggered. Instead, if the remote device determines to deactivate the non-directly connected path, the PDCP entity of the remote device may perform the above behavior.
- the RLC entity of the remote device can be rebuilt.
- the behavior of the RLC entity may be triggered by a first deactivation command.

- the second indication information may occupy one or more bits, for example.
- the first deactivation command is an RRC command, and for example, the RRC command is an RRC reconfiguration message.
- the first deactivation command can also be other types of messages, such as PC5 RRC command, etc., without any specific limitation.
- the behavior of the RLC entity may not be explicitly triggered. Instead, if the remote device determines to deactivate the indirect path, the RLC entity of the remote device may perform the above behavior.
- the MAC entity of the remote device can determine the discontinuous reception (DRX) configuration or modify the DRX configuration.
- a set of DRX configurations may include information such as the DRX cycle (or the duration of the DRX cycle) and/or duration (on duration).
- the process of determining the DRX configuration by the MAC entity is introduced.
- the MAC entity may determine to apply the DRX configuration with a larger DRX cycle. Because the indirect path has been deactivated and data is no longer transmitted on the indirect path, the DRX cycle can be larger to reduce the time the remote device is in the active state, so that the remote device can be in the active state for more time. Sleep state to save power consumption of the remote device.
- the MAC entity (or the remote device) is preconfigured with multiple sets of DRX configurations, or the protocol predefines multiple sets of DRX configurations.
- the MAC entity applies one of them.
- a set of DRX configurations such as a first DRX configuration.
- the MAC entity can determine the DRX configuration, for example, determine whether to replace the first DRX configuration.
- the MAC entity can select one set of DRX configurations from at least one DRX configuration to replace the first DRX configuration.
- Configuration for example, if the MAC entity selects the second DRX configuration, the MAC entity may start applying the second DRX configuration and stop applying the first DRX configuration.
- the second DRX configuration is the DRX configuration with the largest DRX cycle among at least one set of DRX configurations.
- the MAC entity can randomly select a set of DRX configurations from them as the second DRX configuration.
- the MAC entity (or the remote device) is pre-configured with one or more sets of DRX configurations, or the protocol pre-defines one or more sets of DRX configurations.
- the DRX configuration is not applied to the MAC entity.
- the MAC entity can determine the DRX configuration. For example, determining the DRX configuration at this time can also be understood as enabling the DRX configuration.
- the MAC entity can select the DRX configuration with the largest DRX cycle, such as the second DRX configuration, from the multiple sets of DRX configurations, and enable the second DRX configuration.
- the MAC entity can randomly select one set of DRX configurations as the second DRX configuration. Or, if there is only one set of DRX configuration (for example, the DRX configuration is the default DRX configuration), the MAC entity does not need to perform the selection process, but just applies the DRX configuration.
- the following describes the process of modifying the DRX configuration by the MAC entity of the remote device. For example, before the indirect path is deactivated, a set of DRX configuration has been applied to the MAC entity. After the indirect path is deactivated, the MAC entity can modify the DRX configuration, for example, modify the DRX cycle of the DRX configuration to make the DRX cycle longer. Optionally, the MAC entity can modify the DRX cycle of the DRX configuration based on the cycle of PC5 keep alive message (PC5 keep alive message). For example, the cycle of PC5 keep alive message is 5 seconds (s). PC5 keep-alive information is similar to heartbeat information.
- PC5 keep alive message PC5 keep alive message
- the PC5 keep-alive information can be sent periodically between the remote device and the relay device to maintain the connection between the remote device and the relay device.
- the MAC entity can modify the DRX cycle according to the cycle of the PC5 keepalive information.
- the modified DRX cycle is made the same as the cycle of the PC5 keep-alive information, so that the DRX configuration can not only meet the need to maintain the connection, but also save the power consumption of the device.
- processing process of the relay device may include processing actions of one or more entities of the relay device's SRAP entity, RLC entity (eg, PC5 RLC entity), or MAC entity (eg, PC5 MAC entity).
- RLC entity eg, PC5 RLC entity
- MAC entity eg, PC5 MAC entity
- the SRAP entity of the relay device can discard the data corresponding to the indirect path. Because the indirect path has been deactivated, the SRAP entity can stop transmitting data on the indirect path. If there is data corresponding to the indirect path that has not yet been transmitted in the SRAP entity, the SRAP entity can discard the data. For example, discard data packets whose SRAP headers include the ID of the remote device on the deactivated transmission path.
- the SRAP entity may also store an association between the configuration information of the remote device and the configuration information of the Uu interface. The association indicates that the data of the remote device is transmitted through the configuration corresponding to the configuration information of the Uu interface.
- the SRAP entity can retain the association relationship. If the indirect path is reactivated in the future, the SRAP entity can directly apply the association relationship without re-establishing the association relationship.
- the behavior of the SRAP entity may be triggered by a second deactivation command.

Abstract
The present application relates to a communication method and apparatus. The method comprises: a remote device receiving a first deactivation command, which is used for the remote device to deactivate an indirect connection path of the remote device, wherein the remote device communicates with an access network device by means of a direct connection path; and the remote device deactivating the indirect connection path according to the first deactivation command. In the embodiments of the present application, there is no need to release an indirect connection path, but a remote device deactivates the indirect connection path according to a first deactivation command. Since the indirect connection path is not released, if a path needs to be subsequently added to the remote device, the indirect connection path can be reactivated, such that signaling overheads required in the activation process are less than signaling overheads required in a path establishment process, and a communication time delay is also relatively short.

Pending application; this application claims priority to a Chinese patent application filed with the State Intellectual Property Office of China on July 29, 2022, with application number 202210904404.8 and the application title "A communication method and device", the entire content of which is incorporated by reference in this application.
本申请涉及通信技术领域,尤其涉及一种通信方法及装置。The present application relates to the field of communication technology, and in particular, to a communication method and device.
当前已支持远端(remote)用户设备(user equipment,UE)可以通过中继(relay)来连接网络,即,通过非直连(indirect)路径与网络通信。而进一步,又期望支持远端UE可以通过直连(indirect)路径与非直连路径同时通信,以增加远端UE的通信容量。It is currently supported that remote user equipment (user equipment, UE) can connect to the network through a relay, that is, communicate with the network through an indirect path. Furthermore, it is expected to support the remote UE to communicate simultaneously through the indirect path and the indirect path, so as to increase the communication capacity of the remote UE.
在远端UE通过直连路径与非直连路径同时通信的场景下,如果远端UE的业务量变小,则基站可能会释放其中一条路径,如果后续业务量又变大,则可以再次添加路径。而释放路径和添加路径的过程涉及到较多的信令交互过程,开销较大。In a scenario where the remote UE communicates simultaneously through direct paths and indirect paths, if the remote UE's traffic volume becomes smaller, the base station may release one of the paths. If the subsequent traffic volume becomes larger again, the base station may add the path again. . The process of releasing a path and adding a path involves a lot of signaling interaction processes, and the overhead is high.

Access network equipment communicates; deactivate the indirect path according to the first deactivation command.
本申请实施例可以不必释放非直连路径,而是远端设备根据第一去激活命令去激活非直连路径即可。由于并未释放非直连路径,如果后续又要为远端设备添加路径,则将该非直连路径重新激活即可,激活过程相较于建立路径的过程来说所需的信令开销较小,且通信时延也较小。另外,去激活过程相较于释放过程来说,可以不必释放相应的配置,由此也减小了释放过程所带来的时延。In the embodiment of the present application, it is not necessary to release the indirect path, but the remote device only needs to activate the indirect path according to the first deactivation command. Since the indirect path is not released, if you want to add a path to the remote device later, you can just reactivate the indirect path. The activation process requires less signaling overhead than the path establishment process. is small, and the communication delay is also small. In addition, compared with the release process, the deactivation process does not need to release the corresponding configuration, thereby also reducing the delay caused by the release process.

The existing MAC CE can be used to deactivate the cell corresponding to the indirect path. By deactivating the cell, the indirect path in the cell can be deactivated. Alternatively, MAC CE can also be newly defined. The newly defined MAC CE can be used to deactivate the non-directly connected path without having to activate the cell where the non-directly connected path is located, making the deactivation process more targeted. If there are other transmission paths in the cell, the newly defined MAC CE can be used to deactivate the indirect path and retain other transmission paths.

The relay device sends data, and the PDCP entity performs data recovery to recover untransmitted data on the indirect path. After the indirect path is deactivated, the PDCP entity of the remote device can stop sending data to the relay device corresponding to the indirect path to deactivate the indirect path. In addition, before the indirect path is deactivated, the PDCP entity may have sent data to the relay device corresponding to the indirect path, and these data may not be able to reach the remote device because the indirect path is deactivated. end device, which may cause packet loss. Therefore, optionally, the PDCP entity can also perform data recovery to recover untransmitted data on the indirect link. Through the data recovery process, the data that has been submitted to the indirect path can be recovered.

S201、远端设备接收第一去激活命令。S201. The remote device receives the first deactivation command.
例如该远端设备维护了至少两条路径,至少两条路径例如包括一条直连路径和一条非直连路径。可理解为,该远端设备可通过该直连路径与接入网设备通信,另外该远端设备也可以通过该非直连路径与接入网设备通信。第一去激活命令可指示去激活该非直连路径。第一去激活命令的接收端为远端设备,远端设备可以根据第一去激活命令去激活该非直连路径,因此也可以认为,第一去激活命令可用于该远端设备去激活该非直连路径。可选的,如果该非直连路径不是该远端设备的主路径(primary path),例如为该远端设备的辅路径(secondary path),则可以执行本申请实施例提供的方案;如果该非直连路径是该远端设备的主路径,则可以不支持去激活。即,本申请实施例可以应用于去激活辅路径的场景。For example, the remote device maintains at least two paths, and the at least two paths include, for example, a direct path and an indirect path. It can be understood that the remote device can communicate with the access network device through the direct connection path, and in addition, the remote device can also communicate with the access network device through the indirect connection path. The first deactivation command may indicate deactivation of the indirect path. The receiving end of the first deactivation command is a remote device. The remote device can deactivate the indirect path according to the first deactivation command. Therefore, it can also be considered that the first deactivation command can be used by the remote device to deactivate the indirect path. Indirect path. Optionally, if the indirect path is not the primary path of the remote device, for example, the secondary path of the remote device, the solution provided by the embodiment of the present application can be implemented; if the If the indirect path is the main path of the remote device, deactivation does not need to be supported. That is, the embodiment of the present application can be applied to the scenario of deactivating the auxiliary path.
S201可以有不同的实现方式。S201 can be implemented in different ways.
1、第一种实现方式。1. The first implementation method.
在S201中,可以是接入网设备向该远端设备发送第一去激活命令,该远端设备接收来自该接入网设备的第一去激活命令。例如在该远端设备的业务量较小时,接入网设备可以发送第一去激活命令,以减少该远端设备维护的传输路径,节省该远端设备的功耗。例如,该接入网设备可以通过该直连路径或该非直连路径向该远端设备发送第一去激活命令。其中,如果接入网设备通过该非直连路径发送第一去激活命令,则第一去激活命令例如为无线资源控制(radio resource control,RRC)命令或分组数据汇聚协议(packet data convergence protocol,PDCP)控制(control)协议数据单元(protocol data unit,PDU)等。或者,如果接入网设备通过该直连路径发送第一去激活命令,则第一去激活命令例如为RRC命令、PDCP control PDU、或媒体接入控制(media access control,MAC)控制元素(control element,CE)等。In S201, the access network device may send a first deactivation command to the remote device, and the remote device receives the first deactivation command from the access network device. For example, when the traffic volume of the remote device is small, the access network device may send a first deactivation command to reduce the transmission path maintained by the remote device and save power consumption of the remote device. For example, the access network device may send the first deactivation command to the remote device through the direct path or the indirect path. Wherein, if the access network device sends the first deactivation command through the indirect path, the first deactivation command is, for example, a radio resource control (RRC) command or a packet data convergence protocol (packet data convergence protocol, PDCP) control (control) protocol data unit (protocol data unit, PDU), etc. Or, if the access network device sends the first deactivation command through the direct path, the first deactivation command is, for example, an RRC command, a PDCP control PDU, or a media access control (media access control, MAC) control element (control element, CE), etc.
如果第一去激活命令为MAC CE,则该MAC CE的格式可以与用于去激活辅小区(secondary cell,SCell)的MAC CE的格式相同。例如该MAC CE可指示该非直连路径对应的小区,或者说,该MAC CE可用于去激活该非直连路径对应的小区。通过去激活非直连路径对应的小区,也就可以实现对于该非直连路径的去激活。其中,非直连路径对应的小区,例如为该非直连路径上的中继设备所接入的小区。If the first deactivation command is a MAC CE, the format of the MAC CE may be the same as the format of the MAC CE used to deactivate the secondary cell (secondary cell, SCell). For example, the MAC CE can indicate the cell corresponding to the indirect path, or in other words, the MAC CE can be used to deactivate the cell corresponding to the indirect path. By deactivating the cell corresponding to the indirect path, the indirect path can be deactivated. The cell corresponding to the indirect path is, for example, the cell accessed by the relay device on the indirect path.
或者,如果第一去激活命令为MAC CE,则该MAC CE的格式也可以是新定义的,例如该MAC CE用于去激活该非直连路径,而不用于去激活该非直连路径对应的小区。如果该远端设备维护了多条非直连路径,则第一去激活命令可用于去激活这多条非直连路径中的全部或部分非直连路径。可选的,如果第一去激活命令用于去激活这多条非直连路径中的部分非直连路径,则第一去激活命令可以包括所述部分非直连路径所对应的中继设备的标识,以指示究竟去激活哪些非直连路径。例如中继设备的标识为该中继设备的层(layer,L)2身份号(identity,ID)。如果远端设备在该非直连路径对应的小区内有多条路径,则
采用这种方式可以去激活相应的非直连路径而不必去激活该小区,使得远端设备在该小区内的其他路径可以继续工作。Or, if the first deactivation command is MAC CE, the format of the MAC CE may also be newly defined. For example, the MAC CE is used to deactivate the indirect path, but not to deactivate the corresponding indirect path. community. If the remote device maintains multiple indirect paths, the first deactivation command may be used to deactivate all or part of the multiple indirect paths. Optionally, if the first deactivation command is used to deactivate part of the indirect paths among the plurality of indirect paths, the first deactivation command may include the relay device corresponding to the part of the indirect paths. to indicate which indirect paths are to be activated. For example, the identifier of the relay device is the layer (L) 2 identity number (identity, ID) of the relay device. If the remote device has multiple paths in the cell corresponding to the indirect path, then In this way, the corresponding indirect path can be deactivated without deactivating the cell, so that the remote device can continue to work on other paths in the cell.
可选的,在S201的第一种实现方式下,该方法还可以包括S202:远端设备向中继设备发送第二去激活命令,相应的,中继设备接收来自远端设备的第二去激活命令。第二去激活命令可以用于该中继设备去激活该非直连路径。例如S202可以发生在S201之后。另外,该方法还可以包括S203:中继设备根据第二去激活命令去激活该非直连路径。例如S203可以发生在S202之后。相当于,接入网设备指示远端设备去激活非直连路径,由于非直连路径涉及到该远端设备以及该非直连路径上的中继设备,则该远端设备可以向该中继设备发送第二去激活命令,从而该中继设备可以根据第二去激活命令去激活该非直连路径。例如,第二去激活命令为PC5 RRC命令、PC5 MAC CE或侧行中继适配协议(sidelink relay adaptation protocol,SRAP)control PDU等。Optionally, in the first implementation of S201, the method may also include S202: the remote device sends a second deactivation command to the relay device, and accordingly, the relay device receives the second deactivation command from the remote device. Activate command. The second deactivation command may be used by the relay device to deactivate the indirect path. For example, S202 may occur after S201. In addition, the method may also include S203: the relay device deactivates the indirect path according to the second deactivation command. For example, S203 may occur after S202. Equivalently, the access network device instructs the remote device to deactivate the non-directly connected path. Since the non-directly connected path involves the remote device and the relay device on the non-directly connected path, the remote device can send a request to the intermediate device. The relay device sends a second deactivation command, so that the relay device can deactivate the indirect path according to the second deactivation command. For example, the second deactivation command is a PC5 RRC command, a PC5 MAC CE or a sidelink relay adaptation protocol (SRAP) control PDU, etc.
或者,在S201的第一种实现方式下,该方法还可以包括S204:接入网设备向中继设备发送第二去激活命令,相应的,中继设备接收来自接入网设备的第二去激活命令。第二去激活命令可以用于该中继设备去激活该非直连路径。另外该方法还可以包括S203,可参考前文介绍。相当于,接入网设备分别指示远端设备和中继设备去激活非直连路径,从而该中继设备可以根据第二去激活命令去激活该非直连路径,不必由远端设备再向中继设备发送去激活命令。一个中继设备可能会向多个远端设备提供中继服务,因此可选的,第二去激活命令可以包括远端设备的标识,使得该中继设备明确需要“去激活”的是哪个远端设备所对应的非直连路径。例如该远端设备的标识包括该远端设备的本地(local)ID或者L2ID等。例如,第二去激活命令为RRC命令、SRAP control PDU或MAC CE等。Or, in the first implementation of S201, the method may also include S204: the access network device sends a second deactivation command to the relay device, and accordingly, the relay device receives the second deactivation command from the access network device. Activate command. The second deactivation command may be used by the relay device to deactivate the indirect path. In addition, this method can also include S203, please refer to the previous introduction. Equivalently, the access network device respectively instructs the remote device and the relay device to deactivate the non-directly connected path, so that the relay device can deactivate the non-directly connected path according to the second deactivation command without the need for the remote device to activate the non-directly connected path. The relay device sends a deactivation command. A relay device may provide relay services to multiple remote devices, so optionally, the second deactivation command may include the identifier of the remote device, so that the relay device can clearly identify which remote device needs to be "deactivated". The indirect path corresponding to the end device. For example, the identifier of the remote device includes the local ID or L2ID of the remote device. For example, the second deactivation command is an RRC command, SRAP control PDU or MAC CE, etc.
例如,该接入网设备可以通过该直连路径或该非直连路径向该中继设备发送第二去激活命令。其中,S201与S204可以同时执行,或者S201可以在S204之前执行,则这两条命令都可以通过直连路径发送或非直连路径发送,或者这两条命令也可以通过不同的路径发送;或者,S204可以在S201之前执行,则第二去激活命令可以通过直连路径或非直连路径发送,而第一激活命令可以优选通过直连路径发送,因为此时可能中继设备已经开始执行对于该非直连路径的去激活操作,如果第一去激活命令继续通过该非直连路径发送,可能由于中继设备对该非直连路径的去激活而导致第一去激活命令无法到达远端设备。或者,即使S204在S201之前执行,第一去激活命令也可以通过非直连路径或直连路径发送,具体不做限制。For example, the access network device may send the second deactivation command to the relay device through the direct path or the indirect path. Among them, S201 and S204 can be executed at the same time, or S201 can be executed before S204, then these two commands can be sent through a direct path or an indirect path, or the two commands can also be sent through different paths; or , S204 can be executed before S201, then the second deactivation command can be sent through the direct path or the indirect path, and the first activation command can preferably be sent through the direct path, because at this time the relay device may have started to execute the In the deactivation operation of the indirect path, if the first deactivation command continues to be sent through the indirect path, the first deactivation command may not reach the remote end due to the deactivation of the indirect path by the relay device. equipment. Alternatively, even if S204 is executed before S201, the first deactivation command may be sent through an indirect path or a direct path, without any specific limitation.
2、第二种实现方式。2. The second implementation method.
在S201中,可以是中继设备向该远端设备发送第一去激活命令,该远端设备接收来自该中继设备的第一去激活命令。例如,第一去激活命令为PC5 RRC命令、PC5 MAC CE或SRAPcontrol PDU等。In S201, the relay device may send a first deactivation command to the remote device, and the remote device receives the first deactivation command from the relay device. For example, the first deactivation command is PC5 RRC command, PC5 MAC CE or SRAPcontrol PDU, etc.
可选的,在S201的第二种实现方式下,该方法还可以包括S205:接入网设备向中继设备发送第二去激活命令,相应的,中继设备接收来自接入网设备的第二去激活命令。例如S205发生在S201之前。其中,该接入网设备可以通过该直连路径或该非直连路径向该中继设备发送第二去激活命令。第二去激活命令可以用于该中继设备去激活该非直连路径。另外该方法还可以包括S203,可参考前文介绍。例如S203发生在S205之后,而S203与S201可以同时发生,或者S203发生在S201之前,或者S203发生在S201之后。相当于,接入网设备指示该非直连路径对应的中继设备去激活非直连路径,由于非直连路径还涉及
到远端设备,则该中继设备可以向该远端设备发送第一去激活命令,从而该远端设备可以根据第二去激活命令去激活该非直连路径。例如,第二去激活命令为RRC命令、SRAP control PDU或MAC CE等;第一去激活命令例如为PC5 RRC命令、PC5 MAC CE或SRAP control PDU等。Optionally, in the second implementation of S201, the method may also include S205: the access network device sends a second deactivation command to the relay device, and accordingly, the relay device receives the third deactivation command from the access network device. 2. Deactivate the command. For example, S205 occurs before S201. Wherein, the access network device may send the second deactivation command to the relay device through the direct path or the indirect path. The second deactivation command may be used by the relay device to deactivate the indirect path. In addition, this method can also include S203, please refer to the previous introduction. For example, S203 occurs after S205, and S203 and S201 can occur at the same time, or S203 occurs before S201, or S203 occurs after S201. Equivalently, the access network device instructs the relay device corresponding to the indirect path to deactivate the indirect path, because the indirect path also involves to the remote device, the relay device can send the first deactivation command to the remote device, so that the remote device can deactivate the indirect path according to the second deactivation command. For example, the second deactivation command is an RRC command, SRAP control PDU or MAC CE, etc.; the first deactivation command is, for example, a PC5 RRC command, PC5 MAC CE or SRAP control PDU, etc.
也就是说,接入网设备可以通过多种方式指示远端设备和/或中继设备去激活非直连路径,较为灵活。That is to say, the access network device can instruct the remote device and/or the relay device to deactivate the indirect path through various methods, which is more flexible.
可选的,在S201、S204、或S205之前,或者说,在接入网设备发送去激活命令(例如第一去激活命令和/或第二去激活命令)之前,该方法还可包括S206:接入网设备向远端设备发送第一RRC重配置消息,相应的,远端设备接收来自接入网设备的第一RRC重配置消息。第一RRC重配置消息可用于配置该直连路径以及该非直连路径。第一RRC重配置消息要配置该直连路径以及该非直连路径,可以有多种配置方式,如下举例介绍。Optionally, before S201, S204, or S205, or before the access network device sends a deactivation command (such as the first deactivation command and/or the second deactivation command), the method may also include S206: The access network device sends the first RRC reconfiguration message to the remote device, and accordingly, the remote device receives the first RRC reconfiguration message from the access network device. The first RRC reconfiguration message may be used to configure the direct path and the indirect path. The first RRC reconfiguration message is to configure the directly connected path and the indirect path. There can be multiple configuration methods, as shown in the following examples.
例如一种配置方式为,第一RRC重配置消息可包括一个或多个不止一个RLC(morethanoneRLC)信元,这一个或多个morethanoneRLC信元中可以包括第一morethanoneRLC信元,第一morethanoneRLC信元可以包括非直连路径的配置信息,以及包括直连路径的配置信息。第一morethanoneRLC信元所包括的非直连路径的配置信息,可以包括该非直连路径对应的中继设备的标识,以指示该非直连路径。可选的,该非直连路径的配置信息还可以包括非直连路径对应的逻辑信道的标识,该逻辑信道的标识例如为PC5接口上的逻辑信道的标识。可选的,第一morethanoneRLC信元可以指示该远端设备的主路径和/或辅路径,例如指示该直连路径为主路径。第一morethanoneRLC信元的数量可以是一个或多个,其中,如果第一morethanoneRLC信元的数量为多个,则这多个morethanoneRLC信元中都可以包括直连路径的配置信息以及非直连路径的配置信息。在这种方式下,通过修改第一morethanoneRLC信元,可以使得第一morethanoneRLC信元能够配置非直连路径。For example, one configuration method is that the first RRC reconfiguration message may include one or more more than one RLC (morethanoneRLC) information elements, and the one or more morethanoneRLC information elements may include the first morethanoneRLC information element. The first morethanoneRLC information element It can include configuration information of indirect paths and configuration information of direct paths. The configuration information of the indirect path included in the first morethanoneRLC information element may include the identification of the relay device corresponding to the indirect path to indicate the indirect path. Optionally, the configuration information of the indirect path may also include the identifier of the logical channel corresponding to the indirect path. The identifier of the logical channel is, for example, the identifier of the logical channel on the PC5 interface. Optionally, the first morethanoneRLC information element may indicate the primary path and/or the secondary path of the remote device, for example, indicate that the directly connected path is the primary path. The number of first morethanoneRLC cells may be one or more. If the number of first morethanoneRLC cells is multiple, the plurality of morethanoneRLC cells may include configuration information of directly connected paths and indirect paths. configuration information. In this way, by modifying the first morethanoneRLC information element, the first morethanoneRLC information element can be configured to configure an indirect path.
又例如,另一种配置方式为,第一RRC重配置消息可以包括多个morethanoneRLC信元,这多个morethanoneRLC信元中包括第二morethanoneRLC信元,第二morethanoneRLC信元可包括直连路径的配置信息,第二morethanoneRLC信元的数量可以是一个或多个。另外,第一RRC重配置消息还可以包括非直连路径的配置信息,以及包括第一信元。第一信元的数量可以是一个或多个,例如第一信元为不止一个路径(morethanonepath)信元,或者第一信元也可以是其他名称。第一RRC重配置消息所包括的非直连路径的配置信息例如不位于第二morethanoneRLC信元和morethanonepath信元内,即,第一RRC重配置消息包括非直连路径的配置信息,但第一RRC重配置消息内的第二morethanoneRLC信元和morethanonepath信元并不包括该非直连路径的配置信息。该morethanonepath信元可以指示该远端设备的主路径和/或辅路径,例如指示该直连路径为主路径。可选的,该morethanonepath信元还可以包括所指示的路径的信息。例如,该morethanonepath信元指示直连路径(例如指示直连路径为主路径,或指示直连路径为辅路径),则该morethanonepath信元可以包括该直连路径对应的小区的标识;又例如,该morethanonepath信元指示非直连路径(例如指示非直连路径为主路径,或指示非直连路径为辅路径),则该morethanonepath信元可以包括该非直连路径对应的PC5逻辑信道的标识和/或该非直连路径对应的中继设备的标识,例如该中继设备的L2ID。For another example, another configuration method is that the first RRC reconfiguration message may include multiple morethanoneRLC information elements. The multiple morethanoneRLC information elements may include a second morethanoneRLC information element. The second morethanoneRLC information element may include the configuration of the direct path. Information, the number of second morethanoneRLC cells can be one or more. In addition, the first RRC reconfiguration message may also include configuration information of the indirect path and the first information element. The number of the first cell may be one or more. For example, the first cell may be a more than one path cell, or the first cell may also have other names. For example, the configuration information of the indirect path included in the first RRC reconfiguration message is not located in the second morethanoneRLC information element and the morethanonepath information element. That is, the first RRC reconfiguration message includes the configuration information of the indirect path, but the first The second morethanoneRLC information element and the morethanonepath information element in the RRC reconfiguration message do not include the configuration information of the indirect path. The morethanonepath information element may indicate the primary path and/or secondary path of the remote device, for example, indicating the direct path as the primary path. Optionally, the morethanonepath information element may also include information about the indicated path. For example, if the morethanonepath information element indicates a direct path (for example, indicates a direct path as a primary path, or indicates a direct path as a secondary path), then the morethanonepath information element may include the identity of the cell corresponding to the direct path; for another example, If the morethanonepath information element indicates an indirect path (for example, indicates an indirect path as a primary path, or indicates an indirect path as a secondary path), then the morethanonepath information element may include the identification of the PC5 logical channel corresponding to the indirect path. and/or the identification of the relay device corresponding to the indirect path, such as the L2ID of the relay device.
再例如,又一种配置方式为,第一RRC重配置消息包括侧行SRAP配置
(SL-SRAP-Config)信元,该侧行SRAP配置信元可包括直连路径对应的RLC实体的信息,以及包括该非直连路径对应的RLC实体的信息。例如该侧行SRAP配置信元包括数据无线承载(data radio bearer,DRB)的标识以及RLC实体对应的逻辑信道标识(logical channel identifier,LCID),DRB可以对应PDCP实体,相当于该侧行SRAP配置信元可包括PDCP实体与RLC实体之间的对应关系。本申请实施例中,该SRAP配置信元可以包括远端设备的PDCP实体与直连路径对应的RLC实体之间的对应关系,以及还包括该PDCP实体与非直连路径对应的RLC实体之间的对应关系,例如一种实现方式为,该SRAP配置信元包括该PDCP实体对应的DRB的标识与直连路径对应的RLC实体的LCID之间的对应关系,以及包括该PDCP实体对应的DRB的标识与非直连路径对应的RLC实体的LCID之间的对应关系。如果第一RRC重配置消息要为该远端设备配置多条非直连路径,则该SRAP配置信元可以包括这多条非直连路径对应的RLC实体与该远端设备的PDCP实体之间的对应关系。For another example, another configuration method is that the first RRC reconfiguration message includes sidelink SRAP configuration. (SL-SRAP-Config) information element. The sidelink SRAP configuration information element may include information about the RLC entity corresponding to the direct path, and information about the RLC entity corresponding to the indirect path. For example, the sideline SRAP configuration information element includes the identifier of the data radio bearer (DRB) and the logical channel identifier (LCID) corresponding to the RLC entity. The DRB can correspond to the PDCP entity, which is equivalent to the sideline SRAP configuration. The information element may include the correspondence between the PDCP entity and the RLC entity. In this embodiment of the present application, the SRAP configuration information element may include the correspondence between the PDCP entity of the remote device and the RLC entity corresponding to the direct path, and may also include the correspondence between the PDCP entity and the RLC entity corresponding to the indirect path. For example, one implementation method is that the SRAP configuration information element includes the correspondence between the identifier of the DRB corresponding to the PDCP entity and the LCID of the RLC entity corresponding to the direct path, and includes the corresponding relationship between the DRB corresponding to the PDCP entity. Identifies the correspondence between the LCIDs of the RLC entities corresponding to the indirect paths. If the first RRC reconfiguration message is to configure multiple indirect paths for the remote device, the SRAP configuration information element may include the connection between the RLC entities corresponding to the multiple indirect paths and the PDCP entity of the remote device. corresponding relationship.
除此之外,接入网设备还可以通过其他方式为远端设备配置多条传输路径,本申请实施例不做限制。In addition, the access network device can also configure multiple transmission paths for the remote device through other methods, which are not limited by the embodiments of this application.
S207、远端设备根据第一去激活命令,去激活该非直连路径。S207. The remote device deactivates the indirect path according to the first deactivation command.
其中,S207可以发生在S202之前,或者发生在S202之后,或者与S202同时发生。S207可以发生在S204之前,或者发生在S204之后,或者与S204同时发生。S207可以发生在S203之前,或者发生在S203之后,或者与S203同时发生。Among them, S207 can occur before S202, or after S202, or at the same time as S202. S207 can occur before S204, after S204, or simultaneously with S204. S207 can occur before S203, or after S203, or at the same time as S203.
远端设备去激活该非直连路径后,可以不再使用该非直连路径传输数据。但远端设备可以继续保留该非直连路径的配置,如果后续又需要激活该非直连路径,则远端设备重新启用该非直连路径的配置即可。对于中继设备来说也是类似的,中继设备在S203中去激活该非直连路径后,可以不再使用该非直连路径传输数据。但中继设备可以继续保留该非直连路径的配置,如果后续又需要激活该非直连路径,则中继设备重新启用该非直连路径的配置即可。可选的,若该中继设备连接的非直连路径都被去激活,中继设备的Uu口通信也可以被去激活,即可以保留Uu口上的配置,但停止传输。由于远端设备和中继设备并未释放该非直连路径的配置,因此当再次激活该非直连路径时能够减少设备之间由于重新建立传输路径而带来的信令交互过程,节省信令开销,也能减小传输时延。After the remote device deactivates the indirect path, it can no longer use the indirect path to transmit data. However, the remote device can continue to retain the configuration of the indirect path. If the indirect path needs to be activated later, the remote device can re-enable the configuration of the indirect path. The same is true for the relay device. After the relay device deactivates the indirect path in S203, it can no longer use the indirect path to transmit data. However, the relay device can continue to retain the configuration of the indirect path. If the indirect path needs to be activated later, the relay device can re-enable the configuration of the indirect path. Optionally, if all indirect paths connected to the relay device are deactivated, the Uu port communication of the relay device can also be deactivated, that is, the configuration on the Uu port can be retained but transmission stopped. Since the remote device and the relay device do not release the configuration of the indirect path, when the indirect path is activated again, the signaling interaction process caused by re-establishing the transmission path between devices can be reduced, saving signaling. The overhead can also reduce the transmission delay.
在去激活该非直连路径后,远端设备和/或中继设备会有相应的处理过程,下面进行介绍。After deactivating the indirect path, the remote device and/or relay device will have corresponding processing procedures, which are introduced below.
1、远端设备的处理过程。例如,远端设备的处理过程可包括远端设备的PDCP实体、RLC实体(例如PC5 RLC实体)或MAC实体(例如PC5 MAC实体)中的一个或多个实体的处理行为。远端设备可以分别接收多个指示信息,分别指示多个实体的行为,也可以基于一个去激活的指示多个实体的行为。1. The processing process of the remote device. For example, the processing process of the remote device may include processing actions of one or more entities of the PDCP entity, RLC entity (such as PC5 RLC entity) or MAC entity (such as PC5 MAC entity) of the remote device. The remote device can receive multiple indication information respectively, indicating the behaviors of multiple entities respectively, or can also indicate the behaviors of multiple entities based on one deactivation.
远端设备的PDCP实体可以停止向该非直连路径对应的中继设备发送数据。如果该非直连路径被去激活,则该非直连路径不再传输数据,那么该PDCP实体可以停止向该非直连路径对应的中继设备发送数据。另外,在该非直连路径被去激活之前,可能该PDCP实体已经向该非直连路径对应的中继设备发送了数据,而这些数据可能由于该非直连路径被去激活而无法到达远端设备,这可能造成丢包。因此可选的,该PDCP实体还可以进行数据恢复(data recovery),以恢复该非直连链路未传输完成的数据,该未传输完成的数据例如包括已向该中继设备发送的数据。其中,已向该中继设备发送的数据可以包括该PDCP
实体已经递交给下层协议实体(例如RLC实体,SRAP实体)的、需通过该非直连路径传输的数据。可见,通过数据恢复过程,可以恢复已递交给该非直连路径的数据,例如该PDCP实体可以将恢复的数据通过该远端设备未被去激活的传输路径(例如直连路径)传输,从而能够减小丢包率。The PDCP entity of the remote device can stop sending data to the relay device corresponding to the indirect path. If the indirect path is deactivated and no longer transmits data, the PDCP entity may stop sending data to the relay device corresponding to the indirect path. In addition, before the indirect path is deactivated, the PDCP entity may have sent data to the relay device corresponding to the indirect path, and these data may not be able to reach the remote device because the indirect path is deactivated. end device, which may cause packet loss. Therefore, optionally, the PDCP entity can also perform data recovery to recover untransmitted data on the indirect link. The untransmitted data includes, for example, data that has been sent to the relay device. Among them, the data sent to the relay device may include the PDCP The data that the entity has submitted to the lower layer protocol entity (such as RLC entity, SRAP entity) needs to be transmitted through the indirect path. It can be seen that through the data recovery process, the data that has been submitted to the indirect path can be recovered. For example, the PDCP entity can transmit the recovered data through the transmission path (such as the direct path) that has not been deactivated by the remote device, so that Can reduce packet loss rate.
其中,该PDCP实体的行为可以由第一去激活命令触发。例如第一去激活命令可以包括第一指示信息,第一指示信息可以指示该PDCP实体进行数据恢复。第一指示信息例如可占用一个或多个比特(bit)。可选的,第一去激活命令还可以将该远端设备的未被去激活的传输路径(例如直连路径)设置为主路径(primary path),并可以将阈值(threshold)设置为无穷大,使得该PDCP实体不会向该非直连路径对应的中继设备传输数据。其中,该阈值可用于远端设备选择传输路径。例如,如果远端设备待发送的数据量小于该阈值,则只能在主路径上发送数据;或者,如果远端设备待发送的数据量大于该阈值,就可以在主路径和/或辅路径(secondary path)上发送数据。第一去激活命令已将该远端设备的未被去激活的路径设置为主路径,而又将该阈值设置为无穷大,则可以控制远端设备就仅在主路径上发送数据,而不再使用已经被去激活的非直连路径(辅路径)来发送数据。此时,例如第一去激活命令为RRC命令,例如该RRC命令为RRC重配置(RRC reconfiguration)消息。或者,第一去激活命令也可以是其他类型的消息,具体不做限制。Wherein, the behavior of the PDCP entity may be triggered by the first deactivation command. For example, the first deactivation command may include first indication information, and the first indication information may instruct the PDCP entity to perform data recovery. The first indication information may occupy one or more bits, for example. Optionally, the first deactivation command can also set the transmission path (such as a direct path) of the remote device that has not been deactivated as the primary path (primary path), and can set the threshold (threshold) to infinity. This prevents the PDCP entity from transmitting data to the relay device corresponding to the indirect path. Among them, the threshold can be used by the remote device to select a transmission path. For example, if the amount of data to be sent by the remote device is less than the threshold, the data can only be sent on the primary path; or if the amount of data to be sent by the remote device is greater than the threshold, the data can be sent on the primary path and/or the secondary path. Send data on (secondary path). The first deactivation command has set the non-deactivated path of the remote device as the main path, and set the threshold to infinity. Then the remote device can be controlled to only send data on the main path and no longer Data is sent using an indirect path (secondary path) that has been deactivated. At this time, for example, the first deactivation command is an RRC command, and for example, the RRC command is an RRC reconfiguration (RRC reconfiguration) message. Alternatively, the first deactivation command may also be a message of other types, with no specific limitation.
或者,该PDCP实体的行为也可以不进行显式触发,而是如果远端设备确定去激活非直连路径,则该远端设备的PDCP实体就可以执行上述行为。Alternatively, the behavior of the PDCP entity may not be explicitly triggered. Instead, if the remote device determines to deactivate the non-directly connected path, the PDCP entity of the remote device may perform the above behavior.
远端设备的RLC实体可以进行重建。例如,该RLC实体的行为可以由第一去激活命令触发。例如第一去激活命令可以包括第二指示信息,第二指示信息可以指示重建该RLC实体。第二指示信息例如可占用一个或多个比特。此时,例如第一去激活命令为RRC命令,例如该RRC命令为RRC重配置消息。或者,第一去激活命令也可以是其他类型的消息,例如PC5 RRC命令等,具体不做限制。The RLC entity of the remote device can be rebuilt. For example, the behavior of the RLC entity may be triggered by a first deactivation command. For example, the first deactivation command may include second indication information, and the second indication information may indicate reestablishing the RLC entity. The second indication information may occupy one or more bits, for example. At this time, for example, the first deactivation command is an RRC command, and for example, the RRC command is an RRC reconfiguration message. Alternatively, the first deactivation command can also be other types of messages, such as PC5 RRC command, etc., without any specific limitation.
或者,该RLC实体的行为也可以不进行显式触发,而是如果远端设备确定去激活非直连路径,则该远端设备的RLC实体就可以执行上述行为。Alternatively, the behavior of the RLC entity may not be explicitly triggered. Instead, if the remote device determines to deactivate the indirect path, the RLC entity of the remote device may perform the above behavior.
远端设备的MAC实体可以确定非连续接收(discontinuous reception,DRX)配置,或者修改DRX配置。例如,一套DRX配置可包括DRX周期(或者,DRX周期的持续时长)和/或持续时间(on duration)等信息。首先介绍该MAC实体确定DRX配置的过程。该MAC实体在确定DRX配置时,可以确定应用DRX周期较大的DRX配置。因为非直连路径已被去激活,在非直连路径上不再传输数据,因此DRX周期可以较大,以减少远端设备处于激活态的时间,使得远端设备可以在更多时间内处于睡眠状态,以节省远端设备的功耗。The MAC entity of the remote device can determine the discontinuous reception (DRX) configuration or modify the DRX configuration. For example, a set of DRX configurations may include information such as the DRX cycle (or the duration of the DRX cycle) and/or duration (on duration). First, the process of determining the DRX configuration by the MAC entity is introduced. When determining the DRX configuration, the MAC entity may determine to apply the DRX configuration with a larger DRX cycle. Because the indirect path has been deactivated and data is no longer transmitted on the indirect path, the DRX cycle can be larger to reduce the time the remote device is in the active state, so that the remote device can be in the active state for more time. Sleep state to save power consumption of the remote device.
例如,该MAC实体(或者说该远端设备)被预配置了多套DRX配置,或者协议预定义了多套DRX配置,在该非直连路径未被去激活时,该MAC实体应用了其中一套DRX配置,例如第一DRX配置,在该非直连路径被去激活后,该MAC实体可以确定DRX配置,例如确定是否更换第一DRX配置。可选的,如果多套DRX配置中,存在至少一套DRX配置的DRX周期大于第一DRX配置的DRX周期,那么该MAC实体可以从至少一个DRX配置中选择一套DRX配置来替换第一DRX配置,例如该MAC实体选择了第二DRX配置,则该MAC实体可以开始应用第二DRX配置,而停止应用第一DRX配置。例如第二DRX配置为至少一套DRX配置中DRX周期最大的DRX配置。其中,如果至少一
套DRX配置中DRX周期最大的DRX配置的数量大于1,则该MAC实体可以从中随机选择一套DRX配置作为第二DRX配置。For example, the MAC entity (or the remote device) is preconfigured with multiple sets of DRX configurations, or the protocol predefines multiple sets of DRX configurations. When the indirect path is not deactivated, the MAC entity applies one of them. A set of DRX configurations, such as a first DRX configuration. After the indirect path is deactivated, the MAC entity can determine the DRX configuration, for example, determine whether to replace the first DRX configuration. Optionally, if there are multiple sets of DRX configurations, the DRX cycle of at least one DRX configuration is greater than the DRX cycle of the first DRX configuration, then the MAC entity can select one set of DRX configurations from at least one DRX configuration to replace the first DRX configuration. Configuration, for example, if the MAC entity selects the second DRX configuration, the MAC entity may start applying the second DRX configuration and stop applying the first DRX configuration. For example, the second DRX configuration is the DRX configuration with the largest DRX cycle among at least one set of DRX configurations. Among them, if at least one If the number of DRX configurations with the largest DRX cycle in a set of DRX configurations is greater than 1, the MAC entity can randomly select a set of DRX configurations from them as the second DRX configuration.
又例如,该MAC实体(或者说该远端设备)被预配置了一套或多套DRX配置,或者协议预定义了一套或多套DRX配置,在该非直连路径未被去激活时,该MAC实体未应用DRX配置,在该非直连路径被去激活后,该MAC实体可以确定DRX配置,例如此时的确定DRX配置也可以理解为启用DRX配置。可选的,如果有多套DRX配置,则该MAC实体可以从多套DRX配置中选择DRX周期最大的DRX配置,例如第二DRX配置,并启用第二DRX配置。其中,如果这多套DRX配置中DRX周期最大的DRX配置的数量大于1,则该MAC实体可以从中随机选择一套DRX配置作为第二DRX配置。或者,如果仅有一套DRX配置(例如该DRX配置为默认(default)DRX配置),则该MAC实体不必执行选择过程,而是应用该DRX配置即可。For another example, the MAC entity (or the remote device) is pre-configured with one or more sets of DRX configurations, or the protocol pre-defines one or more sets of DRX configurations. When the indirect path is not deactivated, , the DRX configuration is not applied to the MAC entity. After the indirect path is deactivated, the MAC entity can determine the DRX configuration. For example, determining the DRX configuration at this time can also be understood as enabling the DRX configuration. Optionally, if there are multiple sets of DRX configurations, the MAC entity can select the DRX configuration with the largest DRX cycle, such as the second DRX configuration, from the multiple sets of DRX configurations, and enable the second DRX configuration. Among them, if the number of DRX configurations with the largest DRX cycle among the multiple sets of DRX configurations is greater than 1, the MAC entity can randomly select one set of DRX configurations as the second DRX configuration. Or, if there is only one set of DRX configuration (for example, the DRX configuration is the default DRX configuration), the MAC entity does not need to perform the selection process, but just applies the DRX configuration.
下面介绍远端设备的MAC实体修改DRX配置的过程。例如在该非直连路径被去激活前,该MAC实体已应用了一套DRX配置。则在该非直连路径被去激活后,该MAC实体可以修改该DRX配置,例如修改该DRX配置的DRX周期,使得该DRX周期变长。可选的,该MAC实体可以根据PC5保活信息(PC5 keep alive message)的周期来修改该DRX配置的DRX周期,例如PC5保活信息的周期为5秒(s)。PC5保活信息类似于心跳信息,远端设备与中继设备之间可以周期性发送该PC5保活信息,以维持远端设备与中继设备之间的连接。本申请实施例中,虽然该非直连路径被去激活,但远端设备与中继设备之间的连接可以继续维持,因此该MAC实体可以根据PC5保活信息的周期来修改该DRX周期,例如使得修改后的DRX周期与PC5保活信息的周期相同,从而使得该DRX配置既能够满足维持连接的需求,也能节省设备的功耗。The following describes the process of modifying the DRX configuration by the MAC entity of the remote device. For example, before the indirect path is deactivated, a set of DRX configuration has been applied to the MAC entity. After the indirect path is deactivated, the MAC entity can modify the DRX configuration, for example, modify the DRX cycle of the DRX configuration to make the DRX cycle longer. Optionally, the MAC entity can modify the DRX cycle of the DRX configuration based on the cycle of PC5 keep alive message (PC5 keep alive message). For example, the cycle of PC5 keep alive message is 5 seconds (s). PC5 keep-alive information is similar to heartbeat information. The PC5 keep-alive information can be sent periodically between the remote device and the relay device to maintain the connection between the remote device and the relay device. In the embodiment of this application, although the indirect path is deactivated, the connection between the remote device and the relay device can continue to be maintained. Therefore, the MAC entity can modify the DRX cycle according to the cycle of the PC5 keepalive information. For example, the modified DRX cycle is made the same as the cycle of the PC5 keep-alive information, so that the DRX configuration can not only meet the need to maintain the connection, but also save the power consumption of the device.
2、中继设备的处理过程。例如,中继设备的处理过程可包括中继设备的SRAP实体、RLC实体(例如PC5 RLC实体)或MAC实体(例如PC5 MAC实体)中的一个或多个实体的处理行为。2. Processing process of relay equipment. For example, the processing process of the relay device may include processing actions of one or more entities of the relay device's SRAP entity, RLC entity (eg, PC5 RLC entity), or MAC entity (eg, PC5 MAC entity).
可选的,中继设备的SRAP实体可以丢弃该非直连路径对应的数据。因为该非直连路径已被去激活,因此该SRAP实体可以停止在该非直连路径上传输数据。如果该SRAP实体内有尚未传输的该非直连路径对应的数据,则该SRAP实体可以丢弃这些数据。例如,丢弃SRAP包头中包括被去激活的传输路径上的远端设备ID的数据包。另外,该SRAP实体还可以存储有远端设备的配置信息与Uu接口的配置信息之间的关联关系,该关联关系表明该远端设备的数据通过该Uu接口的配置信息对应的配置传输。可选的,该SRAP实体可以保留该关联关系,如果该非直连路径将来被重新激活,则该SRAP实体可以直接应用该关联关系,而不必再重新建立该关联关系。Optionally, the SRAP entity of the relay device can discard the data corresponding to the indirect path. Because the indirect path has been deactivated, the SRAP entity can stop transmitting data on the indirect path. If there is data corresponding to the indirect path that has not yet been transmitted in the SRAP entity, the SRAP entity can discard the data. For example, discard data packets whose SRAP headers include the ID of the remote device on the deactivated transmission path. In addition, the SRAP entity may also store an association between the configuration information of the remote device and the configuration information of the Uu interface. The association indicates that the data of the remote device is transmitted through the configuration corresponding to the configuration information of the Uu interface. Optionally, the SRAP entity can retain the association relationship. If the indirect path is reactivated in the future, the SRAP entity can directly apply the association relationship without re-establishing the association relationship.
例如,该SRAP实体的行为可以由第二去激活命令触发。例如第二去激活命令可以包括第三指示信息,第三指示信息可以指示SRAP实体去激活该非直连路径,或指示SRAP实体丢弃该非直连路径对应的数据。第三指示信息例如可占用一个或多个比特。此时,例如第二去激活命令为RRC命令,例如该RRC命令为RRC重配置消息,或者第二去激活命令也可以是其他消息,例如PC5 RRC命令等,具体不做限制。或者,该SRAP实体的行为也可以不进行显式触发,而是如果中继设备确定去激活非直连路径,则该中继设备的SRAP实体就可以执行上述行为。For example, the behavior of the SRAP entity may be triggered by a second deactivation command. For example, the second deactivation command may include third indication information, and the third indication information may instruct the SRAP entity to deactivate the indirect path, or instruct the SRAP entity to discard data corresponding to the indirect path. The third indication information may occupy one or more bits, for example. At this time, for example, the second deactivation command is an RRC command, for example, the RRC command is an RRC reconfiguration message, or the second deactivation command can also be other messages, such as a PC5 RRC command, etc., and there is no specific limit. Alternatively, the behavior of the SRAP entity may not be explicitly triggered. Instead, if the relay device determines to deactivate the non-directly connected path, the SRAP entity of the relay device may perform the above behavior.
或者,在非直连路径被去激活后,该SRAP实体也可以不进行操作。例如,接入网设
备可以在确定中继设备的SRAP实体内不包括非直连路径对应的数据时,再执行去激活过程,例如执行如上的S201~S205、以及S207。在这种情况下,该SRAP实体可以不进行操作,例如不必执行丢弃该非直连路径对应的数据的操作。Alternatively, after the indirect path is deactivated, the SRAP entity may not perform operations. For example, access network equipment When the device determines that the SRAP entity of the relay device does not include data corresponding to the indirect path, it can then perform the deactivation process, such as performing the above S201 to S205 and S207. In this case, the SRAP entity may not perform an operation, for example, there is no need to perform an operation of discarding data corresponding to the indirect path.
中继设备的RLC实体可以重建,关于该过程可参考前文对于远端设备的RLC实体的行为的介绍。The RLC entity of the relay device can be rebuilt. For this process, please refer to the previous introduction to the behavior of the RLC entity of the remote device.
中继设备的MAC实体可以确定DRX配置或修改DRX配置,关于该内容可以参考前文对于远端设备的MAC实体的行为的介绍。The MAC entity of the relay device can determine the DRX configuration or modify the DRX configuration. For this content, please refer to the previous introduction to the behavior of the MAC entity of the remote device.
如上的各个步骤介绍的是去激活非直连路径的过程,本申请实施例也可保护去激活直连路径的过程。例如远端设备维护了直连路径和非直连路径,如果其中的直连路径为辅路径,则可以去激活该直连路径。例如,接入网设备可以向远端设备发送第三去激活命令,以指示去激活该直连路径,或者指示去激活该直连路径对应的小区,或者指示去激活该直连路径对应的小区所在的辅小区组(secondary cell group,SCG)。远端设备接收第三去激活命令后,可以去激活该直连路径。例如第三去激活命令为MAC CE,该MAC CE可指示去激活该直连路径,或者指示去激活该直连路径对应的小区;或者第三去激活命令为RRC重配置消息,该RRC重配置消息包括SCG状态(scg-state),其中,RRC重配置消息包括scg-state,则表明去激活该SCG。The above steps describe the process of deactivating the indirect path, and the embodiments of the present application can also protect the process of deactivating the direct path. For example, the remote device maintains a direct path and an indirect path. If the direct path is a secondary path, the direct path can be deactivated. For example, the access network device may send a third deactivation command to the remote device to instruct the deactivation of the direct path, or the deactivation of the cell corresponding to the direct path, or the deactivation of the cell corresponding to the direct path. The secondary cell group (SCG) in which it is located. After receiving the third deactivation command, the remote device can deactivate the direct path. For example, the third deactivation command is a MAC CE, and the MAC CE can instruct to deactivate the direct path, or instruct to deactivate the cell corresponding to the direct path; or the third deactivation command is an RRC reconfiguration message, and the RRC reconfiguration message The message includes the SCG state (scg-state). If the RRC reconfiguration message includes scg-state, it indicates that the SCG is deactivated.
本申请实施例可以不必释放相应的传输路径,而是远端设备根据去激活命令去激活该传输路径即可。由于并未释放该传输路径,如果后续又要为远端设备添加该传输路径,则将该传输路径重新激活即可,激活过程相较于建立传输路径的过程来说所需的信令开销较小,且通信时延也较小。另外,去激活过程相较于释放过程来说,可以不必释放相应的配置,由此也减小了释放过程所带来的时延。而且在非直连路径被去激活后,远端设备和/或中继设备可以确定或修改DRX配置,使得DRX周期变长,以节省设备的功耗。In the embodiment of the present application, it is not necessary to release the corresponding transmission path, but the remote device only needs to activate the transmission path according to the deactivation command. Since the transmission path has not been released, if the transmission path needs to be added to the remote device later, the transmission path can be reactivated. The activation process requires less signaling overhead than the process of establishing the transmission path. is small, and the communication delay is also small. In addition, compared with the release process, the deactivation process does not need to release the corresponding configuration, thereby also reducing the delay caused by the release process. Moreover, after the indirect path is deactivated, the remote device and/or the relay device can determine or modify the DRX configuration to make the DRX cycle longer to save power consumption of the device.
图2所示的实施例介绍了去激活传输路径的过程。在传输路径被去激活后,还可能重新被激活。为此本申请实施例提供另一种通信方法,以介绍如何激活传输路径。请参考图3,为该方法的流程图。例如,本申请实施例所涉及的远端设备即为图1A或图1B中的远端设备;本申请实施例所涉及的接入网设备即为图1A或图1B中的接入网设备;本申请实施例所涉及的第一中继设备即为图1A中的中继设备,或者,如果还涉及第二中继设备,则本申请实施例所涉及的第一中继设备即为图1B中的中继设备1,第二中继设备即为图1B中的中继设备2。The embodiment shown in Figure 2 describes the process of deactivating a transmission path. After the transmission path is deactivated, it may be reactivated. For this reason, the embodiment of the present application provides another communication method to introduce how to activate the transmission path. Please refer to Figure 3 for a flow chart of this method. For example, the remote device involved in the embodiment of this application is the remote device in Figure 1A or Figure 1B; the access network device involved in the embodiment of this application is the access network device in Figure 1A or Figure 1B; The first relay device involved in the embodiment of this application is the relay device in Figure 1A. Or, if a second relay device is also involved, the first relay device involved in the embodiment of this application is the relay device in Figure 1B. The relay device 1 in Figure 1B is the relay device 2 in Figure 1B.
可选的,图3所示的实施例可以与图2所示的实施例结合应用,例如图3所示的实施例发生在图2所示的实施例完毕之后;或者,图3所示的实施例也可以不与图2所示的实施例结合,例如可以采用其他方式对第二路径进行去激活,在去激活之后可以执行图3所示的实施例以激活第二路径。Optionally, the embodiment shown in Fig. 3 can be applied in combination with the embodiment shown in Fig. 2. For example, the embodiment shown in Fig. 3 occurs after the embodiment shown in Fig. 2 is completed; or, the embodiment shown in Fig. 3 The embodiment may not be combined with the embodiment shown in FIG. 2 , for example, other methods may be used to deactivate the second path, and after deactivation, the embodiment shown in FIG. 3 may be executed to activate the second path.
S301、远端设备通过第一路径接收第一激活命令。第一激活命令可用于激活第二路径。S301. The remote device receives the first activation command through the first path. The first activation command can be used to activate the second path.
例如该远端设备维护了第一路径,第一路径例如为非直连路径,可将其称为第一非直连路径。可理解为,该远端设备可通过该非直连路径与接入网设备通信。第一激活命令可指示激活第二路径。第一激活命令的接收端为远端设备,远端设备可以根据第一激活命令激活该第二路径,因此也可以认为,第一激活命令可用于该远端设备激活第二路径。其中,第二路径为直连路径或非直连路径,例如将作为第二路径的非直连路径称为第二非直连路径。
For example, the remote device maintains a first path, and the first path is, for example, an indirect path, which may be called a first indirect path. It can be understood that the remote device can communicate with the access network device through the indirect path. The first activation command may indicate activating the second path. The receiving end of the first activation command is a remote device, and the remote device can activate the second path according to the first activation command. Therefore, it can also be considered that the first activation command can be used by the remote device to activate the second path. The second path is a direct path or an indirect path. For example, the indirect path as the second path is called a second indirect path.
可选的,如果第二路径为直连路径,则第一激活命令可以包括该直连路径对应的小区的标识,例如该小区的NR小区标识(NR cell identifier,NCI)、物理小区标识(physical cell identifier,PCI)、或NR小区全局标识(NR cell global identifier,NCGI)中的一项或多项。或者,如果第二路径为第二非直连路径,则第一激活命令可以包括如下一项或多项:第二非直连路径对应的中继设备(例如称为第二中继设备)的标识,第二非直连路径对应的侧行(sidelink,SL)载波的信息,或,第二非直连路径对应的LCID,通过如上一项或多项,可指示第二非直连路径。Optionally, if the second path is a directly connected path, the first activation command may include the identifier of the cell corresponding to the directly connected path, such as the NR cell identifier (NCI), physical cell identifier (physical) of the cell. cell identifier, PCI), or one or more of NR cell global identifier (NR cell global identifier, NCGI). Alternatively, if the second path is a second indirect path, the first activation command may include one or more of the following: the relay device corresponding to the second indirect path (for example, called the second relay device) Identify, the information of the sidelink (SL) carrier corresponding to the second indirect path, or the LCID corresponding to the second indirect path, and the second indirect path can be indicated by one or more of the above items.
S301可以有不同的实现方式。S301 can be implemented in different ways.
1、第一种实现方式。1. The first implementation method.
在S301中,可以是接入网设备通过第一路径向该远端设备发送第一激活命令,该远端设备通过第一路径接收来自该接入网设备的第一激活命令。例如在该远端设备的业务量较大时,接入网设备可以发送第一激活命令,以增加该远端设备维护的传输路径,满足业务传输需求。其中,第一激活命令例如为RRC命令或PDCP control PDU等。该RRC命令例如为RRC重配置消息。In S301, the access network device may send the first activation command to the remote device through the first path, and the remote device receives the first activation command from the access network device through the first path. For example, when the business volume of the remote device is large, the access network device may send a first activation command to increase the transmission path maintained by the remote device to meet the service transmission requirements. The first activation command is, for example, an RRC command or a PDCP control PDU. The RRC command is, for example, an RRC reconfiguration message.
如果第二路径为第二非直连路径,可选的,在S301的第一种实现方式下,该方法还可以包括S302:远端设备向第二中继设备发送第三激活命令,相应的,第二中继设备接收来自远端设备的第三激活命令。第三激活命令可以用于第二中继设备激活第二非直连路径。另外,该方法还可以包括S303:第二中继设备根据第三激活命令激活第二非直连路径。相当于,接入网设备指示远端设备激活第二非直连路径,由于第二非直连路径涉及到该远端设备以及第二非直连路径上的第二中继设备,则该远端设备可以向第二中继设备发送第三激活命令,从而第二中继设备可以根据第三激活命令激活第二非直连路径。例如,第三激活命令为PC5 RRC命令、PC5 MAC CE或SRAP control PDU等。If the second path is a second indirect path, optionally, in the first implementation of S301, the method may also include S302: the remote device sends a third activation command to the second relay device, correspondingly , the second relay device receives the third activation command from the remote device. The third activation command may be used by the second relay device to activate the second indirect path. In addition, the method may also include S303: the second relay device activates the second indirect path according to the third activation command. Equivalently, the access network device instructs the remote device to activate the second indirect path. Since the second indirect path involves the remote device and the second relay device on the second indirect path, the remote device The end device may send a third activation command to the second relay device, so that the second relay device may activate the second indirect path according to the third activation command. For example, the third activation command is PC5 RRC command, PC5 MAC CE or SRAP control PDU, etc.
可选的,当第二路径为第二非直连路径时,第二中继设备激活第二非直连路径所涉及的处理行为,可包括中继设备的SRAP实体和/或MAC实体(例如PC5 MAC实体)的处理行为。Optionally, when the second path is a second indirect path, the processing actions involved in activating the second indirect path by the second relay device may include the SRAP entity and/or the MAC entity of the relay device (for example, PC5 MAC entity) processing behavior.
根据图2所示的实施例的介绍可知,在一条传输路径被去激活时,中继设备的SRAP实体可以丢弃该传输路径对应的数据,例如丢弃SRAP包头中包括被去激活的路径上的远端设备ID的数据包。而本申请实施例中,第二非直连路径被激活,因此第二中继设备的SRAP实体可以不丢弃第二非直连路径对应的数据,即停止丢弃SRAP包头中包括第二非直连路径上的远端设备ID的数据包,以在第二非直连路径上传输数据。因为第二非直连路径被激活,因此该SRAP实体可以在第二非直连路径上传输数据。According to the introduction of the embodiment shown in Figure 2, when a transmission path is deactivated, the SRAP entity of the relay device can discard the data corresponding to the transmission path, for example, discard the remote data on the deactivated path included in the SRAP header. Packet with end device ID. In the embodiment of the present application, the second indirect path is activated, so the SRAP entity of the second relay device may not discard the data corresponding to the second indirect path, that is, stop discarding the second indirect path included in the SRAP header. packet with the remote device ID on the path to transmit data on the second indirect path. Because the second indirect path is activated, the SRAP entity can transmit data on the second indirect path.
例如,该SRAP实体的行为可以由第三激活命令触发。例如第三激活命令可以包括第四指示信息,第四指示信息可以指示SRAP实体激活第二非直连路径,或指示SRAP实体不丢弃第二非直连路径对应的数据。第四指示信息例如可占用一个或多个比特。此时,例如第三激活命令为PC5 RRC命令等,具体不做限制。或者,该SRAP实体的行为也可以不进行显式触发,而是如果第二中继设备确定激活第二非直连路径,则第二中继设备的SRAP实体就可以执行上述行为。For example, the behavior of the SRAP entity may be triggered by a third activation command. For example, the third activation command may include fourth indication information, and the fourth indication information may instruct the SRAP entity to activate the second indirect path, or instruct the SRAP entity not to discard data corresponding to the second indirect path. The fourth indication information may occupy one or more bits, for example. At this time, for example, the third activation command is the PC5 RRC command, etc., and there are no specific restrictions. Alternatively, the behavior of the SRAP entity may not be explicitly triggered. Instead, if the second relay device determines to activate the second indirect path, the SRAP entity of the second relay device may perform the above behavior.
第二中继设备的MAC实体可以停用DRX配置或者修改DRX配置。例如,第二中继设备的MAC实体在第二非直连路径被激活前,使用了DRX配置。那么在第二非直连路径被激活时,第二中继设备可以停止使用该DRX配置,即,停止使用DRX机制,以保证数
据的正常传输。The MAC entity of the second relay device can disable the DRX configuration or modify the DRX configuration. For example, the MAC entity of the second relay device uses the DRX configuration before the second indirect path is activated. Then when the second indirect path is activated, the second relay device can stop using the DRX configuration, that is, stop using the DRX mechanism to ensure data normal transmission of data.
或者,第二中继设备的MAC实体可以修改DRX配置。例如在第二非直连路径被激活前,该MAC实体已应用了一套DRX配置。则如果第二非直连路径被激活,该MAC实体可以修改该DRX配置,例如修改该DRX配置的DRX周期,使得该DRX周期变短,以保证数据的正常传输,减小丢包率。可选的,该MAC实体可以根据第二非直连路径所传输的业务的周期来修改该DRX配置的DRX周期,例如使得修改后的DRX周期与第二非直连路径所传输的业务的周期相同,从而使得该DRX配置能够满足数据传输需求。Alternatively, the MAC entity of the second relay device may modify the DRX configuration. For example, before the second indirect path is activated, a set of DRX configuration has been applied to the MAC entity. If the second indirect path is activated, the MAC entity can modify the DRX configuration, for example, modify the DRX cycle of the DRX configuration to make the DRX cycle shorter to ensure normal transmission of data and reduce the packet loss rate. Optionally, the MAC entity may modify the DRX cycle of the DRX configuration according to the cycle of the service transmitted by the second indirect path, for example, so that the modified DRX cycle is consistent with the cycle of the service transmitted by the second indirect path. The same, so that the DRX configuration can meet the data transmission requirements.
2、第二种实现方式。2. The second implementation method.
在S301中,可以是第一中继设备通过第一路径向该远端设备发送第一激活命令,该远端设备通过第一路径接收来自第一中继设备的第一激活命令。第一中继设备是第一非直连路径对应的中继设备。例如,第一去激活命令为PC5 RRC命令、PC5 MAC CE或SRAP control PDU等。In S301, the first relay device may send the first activation command to the remote device through the first path, and the remote device receives the first activation command from the first relay device through the first path. The first relay device is a relay device corresponding to the first indirect path. For example, the first deactivation command is PC5 RRC command, PC5 MAC CE or SRAP control PDU, etc.
可选的,在S301的第二种实现方式下,该方法还可以包括S304:接入网设备向第一中继设备发送第二激活命令,相应的,第一中继设备接收来自接入网设备的第二激活命令。第二激活命令可以指示激活第二路径,或指示远端设备激活第二路径,或指示向远端设备转发第二激活命令(例如第二激活命令为SRAP control PDU,该SRAP control PDU包括该远端设备的标识;或者,第一中继设备也可以根据第二激活命令对应的LCID确定转发第二激活命令)。则在S301中,第一中继设备可以根据第二激活命令生成第一激活命令,并通过第一路径向远端设备发送第一激活命令;或者,第一中继设备也可以通过第一路径向远端设备转发第二激活命令,此时第一激活命令为第二激活命令。例如,第二激活命令为RRC命令、SRAP control PDU或MAC CE等。其中,第一激活命令与第二激活命令可以是同一类型的消息,例如第二激活命令为SRAP control PDU,则第一激活命令也可以是SRAP control PDU;或者,第二激活命令为RRC命令,则第一激活命令可以是PC5 RRC命令;或者,第二激活命令为MAC CE,则第一激活命令可以是PC5 MAC CE。或者,第一激活命令与第二激活命令也可以是不同类型的消息,例如第二激活命令为MAC CE,第一激活命令为PC5 RRC命令,具体不做限制。Optionally, in the second implementation of S301, the method may also include S304: the access network device sends a second activation command to the first relay device. Correspondingly, the first relay device receives the command from the access network. Second activation command for the device. The second activation command may indicate activating the second path, or instruct the remote device to activate the second path, or instruct the remote device to forward the second activation command (for example, the second activation command is a SRAP control PDU, and the SRAP control PDU includes the remote device. The identification of the terminal device; alternatively, the first relay device may also determine and forward the second activation command based on the LCID corresponding to the second activation command). Then in S301, the first relay device may generate a first activation command according to the second activation command, and send the first activation command to the remote device through the first path; or, the first relay device may also transmit the first activation command through the first path. Forward the second activation command to the remote device, where the first activation command is the second activation command. For example, the second activation command is an RRC command, SRAP control PDU or MAC CE, etc. Wherein, the first activation command and the second activation command can be the same type of message. For example, the second activation command is SRAP control PDU, then the first activation command can also be SRAP control PDU; or the second activation command is an RRC command, Then the first activation command may be the PC5 RRC command; or, if the second activation command is MAC CE, the first activation command may be PC5 MAC CE. Alternatively, the first activation command and the second activation command may also be different types of messages. For example, the second activation command is a MAC CE command and the first activation command is a PC5 RRC command. There is no specific limitation.
如果第二路径为第二非直连路径,则可选的,在S304之后,该方法还可包括S302和S303,对于这两个步骤可参考前文的介绍。If the second path is a second indirect path, optionally, after S304, the method may also include S302 and S303. For these two steps, please refer to the previous introduction.
也就是说,接入网设备可以直接向远端设备发送激活命令,也可以通过中继设备向远端设备发送激活命令,方式较为灵活。In other words, the access network device can directly send the activation command to the remote device, or it can send the activation command to the remote device through the relay device. The method is more flexible.
S305、远端设备根据第一激活命令激活第二路径。S305. The remote device activates the second path according to the first activation command.
其中,S305可以发生在S302之前,或发生在S302之后,或者与S302同时发生。Among them, S305 can occur before S302, or after S302, or at the same time as S302.
例如,远端设备在去激活第二路径后,可以继续保留第二路径的配置。因此在S305中,远端设备重新启用第二路径的配置即可,不必重新建立第二路径。例如第二路径为第二非直连路径,则对于第二中继设备来说也是类似的,第二中继设备去激活第二非直连路径后,可以继续保留第二非直连路径的配置,在前文介绍的S303中,第二中继设备重新启用第二非直连路径的配置即可。由于远端设备(或,远端设备和第二中继设备)并未释放第二路径的配置,因此当再次激活第二路径时能够减少设备之间由于重新建立传输路径而带来的信令交互过程,节省信令开销,也能减小传输时延。For example, after deactivating the second path, the remote device can continue to retain the configuration of the second path. Therefore, in S305, the remote device only needs to re-enable the configuration of the second path, and there is no need to re-establish the second path. For example, if the second path is a second indirect path, the same is true for the second relay device. After the second relay device deactivates the second indirect path, it can continue to retain the second indirect path. Configuration, in S303 introduced above, the second relay device can re-enable the configuration of the second indirect path. Since the remote device (or the remote device and the second relay device) does not release the configuration of the second path, signaling between devices caused by re-establishing the transmission path can be reduced when the second path is activated again. The interactive process saves signaling overhead and reduces transmission delay.
远端设备可以通过相应的方式激活第二路径,下面进行介绍。
The remote device can activate the second path through corresponding methods, which are introduced below.
1、第二路径为直连路径。1. The second path is a direct path.
当第二路径为直连路径时,远端设备激活直连路径的行为可以包括如下一项或多项:在该直连路径对应的小区监听下行控制信道,与该直连路径对应的小区进行随机接入,或,远端设备的PDCP实体向远端设备中与该直连路径对应的RLC实体传输数据。When the second path is a direct path, the remote device's behavior of activating the direct path may include one or more of the following: monitoring the downlink control channel in the cell corresponding to the direct path, and communicating with the cell corresponding to the direct path. Random access, or the PDCP entity of the remote device transmits data to the RLC entity corresponding to the direct path in the remote device.
其中,远端设备在该直连路径对应的小区监听下行控制信道,例如为在该小区监听物理下行控制信道(physical downlink control channel,PDCCH)。Among them, the remote device monitors the downlink control channel in the cell corresponding to the direct path, for example, monitors the physical downlink control channel (PDCCH) in the cell.
远端设备与该直连路径对应的小区进行随机接入,例如,该远端设备可以在该小区监听PDCCH,如果接收到PDCCH命令(order),则该远端设备可以与该小区进行随机接入,例如该远端设备可以向该小区发送随机接入前导(preamble);或者,该远端设备也可以在接收到第一激活命令后,即可与该小区进行随机接入,例如向该小区发送preamble。The remote device performs random access to the cell corresponding to the direct path. For example, the remote device can monitor the PDCCH in the cell. If the PDCCH command (order) is received, the remote device can perform random access to the cell. For example, the remote device can send a random access preamble to the cell; or, after receiving the first activation command, the remote device can perform random access with the cell, for example, send a random access preamble to the cell. The cell sends the preamble.
2、第二路径为第二非直连路径。2. The second path is the second indirect path.
当第二路径为第二非直连路径时,远端设备激活第二路径所涉及的处理行为,可包括远端设备的PDCP实体、RLC实体(例如PC5 RLC实体)或MAC实体(例如PC5 MAC实体)中的一个或多个实体的处理行为。When the second path is a second indirect path, the processing behavior involved in activating the second path by the remote device may include the PDCP entity, RLC entity (such as PC5 RLC entity) or MAC entity (such as PC5 MAC entity) of the remote device. The processing behavior of one or more entities in the entity).
远端设备的PDCP实体可以向该远端设备中与第二非直连路径对应的SRAP实体传输数据。The PDCP entity of the remote device may transmit data to the SRAP entity corresponding to the second indirect path in the remote device.
其中,该PDCP实体的行为可以由第一激活命令触发。例如第一激活命令可以包括第五指示信息,第五指示信息可以指示该PDCP实体传输第二非直连路径对应的数据。第五指示信息例如可占用一个或多个比特。可选的,第一激活命令还可以将阈值设置的较小,使得该PDCP实体可以向第二非直连路径对应的中继设备传输数据。在前文介绍了,该阈值可用于远端设备选择传输路径。例如,如果远端设备待发送的数据量小于该阈值,则只能在主路径上发送数据;或者,如果远端设备待发送的数据量大于该阈值,就可以在主路径和/或辅路径上发送数据。例如第一路径为该远端设备的主路径,第二非直连路径为该远端设备的辅路径,而第一激活命令又将该阈值设置的较小,则远端设备既可以在主路径上发送数据,也可以在第二非直连路径上发送数据。此时,例如第一去激活命令为RRC命令,例如该RRC命令为RRC重配置消息。或者,第一去激活命令也可以是其他类型的消息,具体不做限制。Wherein, the behavior of the PDCP entity may be triggered by the first activation command. For example, the first activation command may include fifth indication information, and the fifth indication information may instruct the PDCP entity to transmit data corresponding to the second indirect path. The fifth indication information may occupy one or more bits, for example. Optionally, the first activation command can also set the threshold smaller, so that the PDCP entity can transmit data to the relay device corresponding to the second indirect path. As introduced earlier, this threshold can be used by the remote device to select a transmission path. For example, if the amount of data to be sent by the remote device is less than the threshold, the data can only be sent on the primary path; or if the amount of data to be sent by the remote device is greater than the threshold, the data can be sent on the primary path and/or the secondary path. Send data on. For example, the first path is the primary path of the remote device, the second indirect path is the secondary path of the remote device, and the first activation command sets the threshold smaller, then the remote device can either Data is sent on the path, or data can be sent on the second indirect path. At this time, for example, the first deactivation command is an RRC command, and for example, the RRC command is an RRC reconfiguration message. Alternatively, the first deactivation command may also be a message of other types, with no specific limitation.
或者,该PDCP实体的行为也可以不进行显式触发,而是如果远端设备确定激活第二非直连路径,则该远端设备的PDCP实体就可以执行上述行为。Alternatively, the behavior of the PDCP entity may not be explicitly triggered. Instead, if the remote device determines to activate the second indirect path, the PDCP entity of the remote device may perform the above behavior.
远端设备的SRAP实体可以向该远端设备中与第二非直连路径对应的RLC实体传输数据,或者,该SRAP实体可以向远端设备中与该SRAP实体关联的RLC实体传输数据。可选的,该SRAP实体向该RLC实体发送的数据可包括SRAP包头(header),该SRAP包头内可包括该远端设备的标识,例如该远端设备的local ID。The SRAP entity of the remote device may transmit data to the RLC entity corresponding to the second indirect path in the remote device, or the SRAP entity may transmit data to the RLC entity associated with the SRAP entity in the remote device. Optionally, the data sent by the SRAP entity to the RLC entity may include a SRAP header, and the SRAP header may include the identifier of the remote device, such as the local ID of the remote device.
例如,该SRAP实体的行为可以由第一激活命令触发。例如第一激活命令可以包括第六指示信息,第六指示信息可以指示SRAP实体激活第二非直连路径,或指示SRAP实体不丢弃第二非直连路径对应的数据。第六指示信息例如可占用一个或多个比特。此时,例如第一激活命令为RRC命令,例如该RRC命令为RRC重配置消息,或者第一激活命令也可以是其他消息,例如PC5 RRC命令等,具体不做限制。或者,该SRAP实体的行为也可以不进行显式触发,而是如果远端设备确定激活第二非直连路径,则该远端设备的SRAP实体就可以执行上述行为。
For example, the behavior of the SRAP entity may be triggered by a first activation command. For example, the first activation command may include sixth indication information, and the sixth indication information may instruct the SRAP entity to activate the second indirect path, or instruct the SRAP entity not to discard data corresponding to the second indirect path. The sixth indication information may occupy one or more bits, for example. At this time, for example, the first activation command is an RRC command, for example, the RRC command is an RRC reconfiguration message, or the first activation command can also be other messages, such as a PC5 RRC command, etc., and is not specifically limited. Alternatively, the behavior of the SRAP entity may not be explicitly triggered. Instead, if the remote device determines to activate the second indirect path, the SRAP entity of the remote device may perform the above behavior.
远端设备的MAC实体可以停用DRX配置或者修改DRX配置,对此可参考S303中对于第二中继设备的MAC实体的行为的介绍。The MAC entity of the remote device can disable the DRX configuration or modify the DRX configuration. For this, please refer to the introduction to the behavior of the MAC entity of the second relay device in S303.
如上的各个步骤介绍的是通过非直连路径激活第二路径的过程,本申请实施例也可保护通过直连路径激活第二路径的过程。例如,接入网设备可以通过直连路径向远端设备发送第三激活命令,以指示激活第二路径,或者指示激活第二路径对应的小区,或者指示激活第二路径对应的小区所在的SCG。远端设备接收第三激活命令后,可以激活第二路径。例如第三激活命令为MAC CE,该MAC CE可指示激活该直连路径,或者指示激活该直连路径对应的小区;或者第三激活命令为RRC重配置消息,该RRC重配置消息不包括scg-state,或者如果第二路径为非直连路径,则该RRC重配置消息可以不包括第二中继设备对应的小区组(cell group)的状态信息。其中,RRC重配置消息不包括scg-state,则表明激活该SCG;或者,RRC重配置消息不包括第二中继设备对应的小区组的状态信息,则表明激活该小区组。The above steps describe the process of activating the second path through an indirect path. The embodiments of the present application can also protect the process of activating the second path through a direct path. For example, the access network device may send a third activation command to the remote device through a direct path to instruct the activation of the second path, or the activation of the cell corresponding to the second path, or the activation of the SCG where the cell corresponding to the second path is located. . After receiving the third activation command, the remote device can activate the second path. For example, the third activation command is a MAC CE, which can indicate activation of the direct path, or the activation of the cell corresponding to the direct path; or the third activation command is an RRC reconfiguration message, and the RRC reconfiguration message does not include scg -state, or if the second path is an indirect path, the RRC reconfiguration message may not include the status information of the cell group corresponding to the second relay device. Wherein, if the RRC reconfiguration message does not include scg-state, it indicates that the SCG is activated; or, if the RRC reconfiguration message does not include the status information of the cell group corresponding to the second relay device, it indicates that the cell group is activated.
本申请实施例中,在传输路径被去激活后,还可以再次激活。由于传输路径被去激活时相应设备并未释放该传输路径的配置信息,因此设备根据保存的配置信息就可以激活该传输路径,能够节省由于建立传输路径而带来的信令开销以及时延。通过本申请实施例的技术方案,能够灵活改变传输路径的状态,有利于业务传输,也有利于节省设备的功耗。In this embodiment of the present application, after the transmission path is deactivated, it can be activated again. Since the corresponding device does not release the configuration information of the transmission path when the transmission path is deactivated, the device can activate the transmission path based on the saved configuration information, which can save the signaling overhead and delay caused by establishing the transmission path.
