Description

多路径的处理方法、装置、设备以及系统 技术领域
本申请实施例涉及通信技术领域。
背景技术
在版本17(Release 17)中研究了边链路中继(Sidelink relay，SL relay)，其包含终端设备到网络中继(UE-to-Network Relay)的场景。在该场景下，远程用户设备(remote UE)通过中继用户设备(relay UE)与网络设备进行通信。其中，在中继用户设备的Uu链路上使用NR Uu，在远程用户设备和中继用户设备之间的PC5接口上使用NR边链路(NR sidelink)。在UE-to-Network Relay的场景下，relay UE又被称为UE-to-Network relay UE。
应该注意，上面对技术背景的介绍只是为了方便，对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现：在Release 17中，远程用户设备可以通过中继的方式与网络设备进行通信，或者，远程用户设备可以直接与网络设备通信。换句话说，在Release 17中，远程用户设备同时只支持单条路径(path)与网络设备进行通信。
在版本18(Release 18)中，将研究支持多路径(multi-path或multiple path)的方案。多路径的场景可以是：远程用户设备同时使用一个直接路径(direct path)和一个间接路径(indirect path)连接到同一个网络设备(例如，gNB)。例如，直接路径是指远程用户设备通过Uu接口直接连接到网络设备，间接路径可以是指远程用户设备通过层2(Layer-2，L2)UE-to-Network relay连接到网络设备。
目前，在多路径(multi-path)的方案中，如何同时激活至少两个路径(直接路径和间接路径)以及如何在至少两个路径之间进行动态切换，目前并没有解决方案。
针对上述问题的至少之一，本申请实施例提供一种多路径的处理方法、装置、设备以及系统。
根据本申请实施例的一个方面，提供一种多路径的处理装置，包括：
接收单元，其接收指示信息，所述指示信息包括直接路径的激活和/或去激活和/或切换的信息，和/或，包括间接路径的激活和/或去激活和/或切换的信息；以及
处理单元，其根据所述指示信息进行所述直接路径的激活和/或去激活和/或切换，和/或，进行所述间接路径的激活和/或去激活和/或切换。
根据本申请实施例的另一个方面，提供一种多路径的处理方法，包括：
接收指示信息，所述指示信息包括直接路径的激活和/或去激活和/或切换的信息，和/或，包括间接路径的激活和/或去激活和/或切换的信息；以及
根据所述指示信息进行所述直接路径的激活和/或去激活和/或切换，和/或，进行所述间接路径的激活和/或去激活和/或切换。
根据本申请实施例的另一个方面，提供一种远程用户设备，包括存储器和处理器，所述存储器存储有计算机程序，所述处理器被配置为执行所述计算机程序而实现如本申请实施例的另一个方面所述的多路径的处理方法。
根据本申请实施例的另一个方面，提供一种多路径的处理装置，包括：
发送单元，其向远程用户设备(remote UE)或中继用户设备(relay UE)发送指示信息；其中，所述指示信息包括直接路径的激活和/或去激活和/或切换的信息，和/或，包括间接路径的激活和/或去激活和/或切换的信息。
根据本申请实施例的另一个方面，提供一种多路径的处理方法，包括：
向远程用户设备(remote UE)或中继用户设备(relay UE)发送指示信息，所述指示信息包括直接路径的激活和/或去激活和/或切换的信息，和/或，间接路径的激活和/或去激活和/或切换的信息。
根据本申请实施例的另一个方面，提供网络设备，包括存储器和处理器，所述存储器存储有计算机程序，所述处理器被配置为执行所述计算机程序而实现如本申请实施例的另一个方面所述的多路径的处理方法。
根据本申请实施例的另一个方面，提供一种多路径的处理装置，包括：
接收单元，其接收网络设备发送的第二指示信息，所述第二指示信息包括间接路径的激活和/或去激活和/或切换的信息。
根据本申请实施例的另一个方面，提供一种多路径的处理方法，包括：
接收网络设备发送的第二指示信息，所述第二指示信息包括间接路径的激活和/ 或去激活和/或切换的信息。
根据本申请实施例的另一个方面，提供一种中继用户设备，包括存储器和处理器，所述存储器存储有计算机程序，所述处理器被配置为执行所述计算机程序而实现如本申请另一个方面所述的多路径的处理方法。
根据本申请实施例的另一个方面，提供一种通信系统，包括如本申请实施例的另一个方面所述的网络设备和/或远程用户设备和/或中继用户设备。
本申请实施例的有益效果之一在于：远程用户设备接收指示信息并根据该指示信息进行直接路径的激活和/或去激活和/或切换，和/或，进行间接路径的激活和/或去激活和/或切换。由此，能够在多路径方案中对远程用户设备的路径进行激活和/或去激活和/或切换，有助于动态地调整多路径中各路径的使用，提高远程用户设备的数据传输的可靠性和速率。

根据上述实施例，远程用户设备可以接收指示信息并根据该指示信息进行直接路径的激活和/或去激活和/或切换，和/或，远程用户设备可以接收指示信息并根据该指示信息进行间接路径的激活和/或去激活和/或切换。由此，在多路径方案中，能够对远程用户设备的路径进行激活和/或去激活和/或切换，有助于动态地调整多路径中各路径的使用，提高远程用户设备的数据传输的可靠性和速率。
在本申请实施例中，可以对直接路径和/或间接路径进行激活。
待激活的直接路径可以是在远程用户设备和网络设备之间已配置好的直接路径，该路径可以处于去激活状态或刚被配置的状态。本申请不限于此，待激活的直接路径也可以是处于激活状态的路径，由此，通过上述指示信息在远程用户设备和网络设备之间重新或再次激活直接路径。
待激活的间接路径可以是在远程用户设备和网络设备之间已配置好的间接路径，该路径可以处于去激活状态或刚被配置的状态。本申请不限于此，待激活的间接路径也可以是处于激活状态的路径，通过上述指示信息在远程用户设备和网络设备之间重新或再次激活间接路径。
在一些实施例中，在对直接路径激活时，远程用户设备和网络设备之间可以存在间接路径，由此，可以通过该间接路径传递该指示信息。
在一些实施例中，在对间接路径激活时，远程用户设备和网络设备之间可以存在直接路径，由此，可以通过该直接路径传递该指示信息。
在本申请实施例中，可以对直接路径和/或间接路径进行去激活。
在对直接路径进行去激活之后，远程用户设备和网络设备可以保留该去激活状态的直接路径的配置，以便于在后续通信过程中通过上述指示信息激活该直接路径，以快速地恢复该直接路径。本申请不限于此，远程用户设备和网络设备可以不保留该去激活状态的直接路径的配置，通过网络设备的配置信息再配置直接路径。
在对间接路径进行去激活之后，远程用户设备和网络设备可以保留该去激活状态的间接路径的配置，以便于在后续通信过程中通过上述指示信息激活该间接路径，以快速地恢复该间接路径。本申请不限于此，远程用户设备和网络设备可以不保留该去激活状态的间接路径的配置，通过网络设备的配置信息再配置间接路径。
在一些实施例中，在对直接路径去激活时，远程用户设备和网络设备之间除了该直接路径之外还可以存在间接路径，该间接路径可以是激活或去激活的状态。或者，在对直接路径去激活时，远程用户设备和网络设置之间也可以不存在间接路径，例如间接路径未被配置。
在一些实施例中，在对间接路径去激活时，远程用户设备和网络设备之间除了该间接路径之外还可以存在直接路径，该直接路径可以是激活或去激活的状态。或者，在对间接路径去激活时，远程用户设备和网络设置之间也可以不存在直接路径，例如直接路径未被配置。
在本申请实施例中，可以对直接路径和/或间接路径进行切换。
直接路径的切换或间接路径的切换可以是如下的至少之一：由直接路径切换成间接路径，或者，由间接路径切换成直接路径，或者，由多路径(直接路径和间接路径)切换成直接路径，或者，由多路径(直接路径和间接路径)切换成间接路径，或者，由直接路径切换成多路径(直接路径和间接路径)，或者，由间接路径切换成多路径(直接路径和间接路径)，等等。
在一些实施例中，可以根据信道状态信息动态地对直接路径和/或间接路径进行激活和/或去激活和/或切换。由此，有助于动态地选择质量较好的和/或时延较低的路径进行通信，从而，能够节约Uu接口和/或PC5接口的无线资源和/或减少数据传输时延。本申请不限于此，也可以根据其他指标对直接路径和/或间接路径进行激活和/或去激活和/或切换。
在一些实施例中，直接路径和间接路径可以采用多于一种传输方式。
例如，直接路径和间接路径可以采用分裂(split)传输的方式，例如，网络设备 对一个远程用户设备的所有无线承载或一个无线承载，可以配置直接路径和间接路径采用分裂(split)传输的方式。在此情况下，直接路径和间接路径可以传输不同的数据，例如，不同的PDCP PDU。由此，能够增加吞吐量。
例如，一部分PDCP PDU可以在直接路径包括的该RB对应的所有RLC实体和/或逻辑信道中被传输，另一部分PDCP PDU可以在间接路径包括的该RB对应的所有RLC实体和/或逻辑信道中被传输。
又例如，一部分PDCP PDU可以在直接路径包括的该RB对应的一个或多于一个RLC实体和/或逻辑信道中被传输，另一部分PDCP PDU可以在直接路径包括的该RB对应的另外一个或多于一个RLC实体和/或逻辑信道中被传输，再另外一部分PDCP PDU可以在间接路径中包括的该RB对应的所有RLC实体和/或逻辑信道中被传输。
再例如，一部分PDCP PDU可以在直接路径包括的该RB对应的所有RLC实体和/或逻辑信道中被传输，另一部分PDCP PDU可以在间接路径中包括的该RB对应的一个或多于一个RLC实体和/或逻辑信道中被传输，再另外一部分PDCP PDU可以在间接路径中包括的该RB对应的另外一个或多于一个RLC实体和/或逻辑信道中被传输。
再例如，一部分PDCP PDU可以在直接路径包括的该RB对应的一个或多于一个RLC实体和/或逻辑信道中被传输，另一部分PDCP PDU可以在直接路径包括的该RB对应的另外一个或多于一个RLC实体和/或逻辑信道中被传输，再另外一部分PDCP PDU可以在间接路径中包括的该RB对应的一个或多于一个RLC实体和/或逻辑信道中被传输，再另外一部分PDCP PDU可以在间接路径中包括的该RB对应的另外一个或多于一个RLC实体和/或逻辑信道中被传输，等等。
例如，直接路径和间接路径可以采用重复(duplication)传输的方式，例如，网络设备对一个远程用户设备的所有无线承载或一个无线承载，可以配置直接路径和间接路径采用duplication传输的方式。在此情况下，直接路径和间接路径可以传输相同的数据，例如，相同的PDCP PDU，这些相同的PDCP PDU也可以在直接路径包括的该RB对应的所有RLC实体和/或逻辑信道中和间接路径包括的该RB对应的所有RLC实体和/或逻辑信道中被传输。由此，能够保证远程用户设备的数据传输的可靠性。
在一些实施例中，网络设备和/或远程用户设备可以根据信道状态信息、业务类 型信息等动态地选择直接路径和间接路径的传输方式。由此，有助于增加通信系统的吞吐量、保证数据传输质量。本申请不限于此，也可以根据其他指标选择该传输方式。
在一些实施例中，远程用户设备可以接收网络设备发送的指示信息，例如，远程用户设备可以通过直接路径接收该指示信息。或者，远程用户设备也可以接收中继用户设备发送的指示信息，例如，远程用户设备通过PC5接口或sidelink接收该指示信息。
以下，为了便于描述，将网络设备发送的指示信息称为第一指示信息，将中继用户设备发送的指示信息称为第三指示信息。
在一些实施例中，第一指示信息可以包括如下的至少一个：

在一些实施例中，第一指示信息中的DRB标识可以是与待激活/待切换的路径对应的DRB标识，或者DRB标识可以是与待去激活的路径对应的DRB标识。远程用户设备可以在接收到DRB标识之后，根据该DRB标识以及DRB标识与路径的对应相关对相应的路径进行激活和/或去激活和/或切换。
在一些实施例中，网络设备向远程用户设备发送的第一指示信息可以包括对直接路径的指示信息，或者，对间接路径的指示信息，或者，对直接路径和间接路径这两者的指示信息。在第一指示信息中，可以通过路径标识或索引对直接路径和间接路径进行区分。其中，远程用户设备可以通过直接路径接收网络设备发送的对直接路径本身进行去激活/切换的信息，或者，可以通过直接路径接收对间接路径进行激活/去激活/切换的信息。
在一些实施例中，逻辑信道标识或索引或RLC实体(或承载或信道)标识或索引用于：在间接路径的PC5接口上支持一个无线承载使用多于一个RLC实体(或承载或信道)和/或逻辑信道传输的情况下，对RLC实体(或承载或信道)和/或逻辑信道进行激活或去激活。

在一些实施例中，第一指示信息可以通过位图(bitmap)来指示DRB标识或索引对应的路径的激活或去激活状态。由此，能够减少信令开销。
图8是本申请第一方面的实施例的位图的一示意图。如图8所示，该位图可以用于指示与DRB对应的直接路径和/或间接路径的激活或去激活状态。例如，以直接路径为例，在直接路径可以用于n个DRB的数据传输的情况下，通过位图(b 0,b 1,…,b i,…,b n-1)(其中，n大于或等于1，i大于或等于0并且小于或等于n)分别指示DRB索引0到n-1对应路径的激活或去激活状态，或者通过位图(b n-1,b n-2,…,b i,…,b 0)分别指示DRB索引n-1到0对应的路径的激活或去激活状态，其中DRB索引根据DRB ID的升序或降序排序。以位图(b 0,b 1,…,b i,…,b n-1)为例，在远程用户设备从直接路径接收到该位图且该位图中的一个比特指示激活的情况下，对该比特对应的DRB的直接路径进行激活；在该位图中的一个比特指示去激活的情况下，对该比特对应的DRB的直接路径进行去激活。间接路径的激活和去激活的判断方式与直接路径类似，此处不再展开说明。本申请不限于此，也可以通过其他形式的位图指示路径的激活或去激活状态。在一些实施例中，第一指示信息可以通过无线资源控制(Radio Resource Control，RRC)消息或分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)控制分组数据单元(packet data unit，PDU)或媒体访问控制(Media Access Control，MAC)控制元素(Control Element，CE)发送。本申请不限于此，第一指示信息也可以通过其他方式发送。

本申请不限于此，中继用户设备向远程用户设备发送的第三指示信息也可以包括 对直接路径的指示信息。其中，远程用户设备可以通过间接路径接收对直接路径进行激活/去激活/切换的信息。
在一些实施例中，第三指示信息中的DRB标识可以是与待激活/待切换的路径对应的DRB标识，或者DRB标识可以是与待去激活的路径对应的DRB标识。远程用户设备可以在接收到DRB标识之后，根据该DRB标识对相应的路径进行激活和/或去激活和/或切换，例如，对与该中继用户设备之间的PC5连接进行激活和/或去激活和/或切换。
在一些实施例中，第三指示信息中的逻辑信道标识或索引或RLC实体(或承载或信道)标识或索引用于：在间接路径的PC5接口上支持一个无线承载使用多于一个RLC实体(或承载或信道)和/或逻辑信道传输的情况下，对RLC实体(或承载或信道)和/或逻辑信道进行激活或去激活。
在一些实施例中，第三指示信息中的路径状态指示信息可以是指示对直接路径和/或间接路径进行激活和/或去激活和/或切换的信息。
在一些实施例中，第三指示信息可以通过PC5无线资源控制(Radio Resource Control，RRC)消息或PC5边链路中继适配协议(Sidelink Relay Adaptation Protocol，SRAP)控制分组数据单元(packet data unit，PDU)或PC5媒体访问控制(Media Access Control，MAC)控制元素(Control Element，CE)发送。本申请不限于此，第三指示信息也可以通过其他方式发送。
在一些实施例中，第三指示信息可以通过位图(bitmap)来指示DRB标识或索引对应的路径的激活或去激活状态。由此，能够减少信令开销。
在一些实施例中，中继用户设备发送的第三指示信息可以是中继用户设备自己生成的信息。或者，第三指示信息也可以是中继用户设备根据网络设备发送的指示信息(例如，该指示信息可以是后面实施例所述的第二指示信息)生成的信息。换句话说，中继用户设备接收网络设备发送的指示信息，根据该指示信息生成发送给远程用户设备的第三指示信息。
在一些实施例中，网络设备发送给中继用户设备的指示信息可以包括如下中的至少一个：DRB标识、逻辑信道标识(LCID)或索引、RLC实体(或承载或信道)标识或索引、或路径状态指示信息。该指示信息中的各信息的内容可以与前述的第三指示信息中的对应信息的内容相同或类似，此处不再展开说明。或者，该指示信息也可 以通过bitmap来指示DRB标识或索引对应的路径的激活或去激活状态。
在一些实施例中，网络设备发送给中继用户设备的指示信息可以通过RRC消息或PDCP控制PDU(PDCP control PDU)或MAC CE发送。本申请不限于此，该指示信息也可以通过其他方式发送。
在一些实施例中，远程用户设备可以接收网络设备发送的第一指示信息或中继用户设备发送的第三指示信息，根据该第一指示信息或第三指示信息对路径进行激活和/或去激活和/或切换。或者，远程用户设备也可以接收网络设备发送的第一指示信息以及中继用户设备发送的第三指示信息，根据该第一指示信息和第三指示信息对路径进行激活和/或去激活和/或切换。
