请参考图1，其示出了本申请一个实施例提供的网络架构的示意图。该网络架构可以包括：核心网11、接入网12和终端设备13。Please refer to FIG1 , which shows a schematic diagram of a network architecture provided by an embodiment of the present application. The network architecture may include: a core network 11 , an access network 12 , and a terminal device 13 .

核心网11中包括若干核心网设备。核心网设备的功能主要是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。例如，5G(5th Generation，第五代移动通信技术)NR(New Radio，新空口)系统的核心网中可以包括AMF(Access and Mobility Management Function，接入和移动性管理功能)实体、UPF(User Plane Function，用户平面功能)实体和SMF(Session Management Function，会话管理功能)实体等设备。The core network 11 includes several core network devices. The functions of the core network devices are mainly to provide user connection, user management and service bearing, and to provide an interface to the external network as a bearer network. For example, the core network of the 5G (5th Generation) NR (New Radio) system may include AMF (Access and Mobility Management Function) entity, UPF (User Plane Function) entity and SMF (Session Management Function) entity and other devices.

接入网12中包括若干接入网设备14。5G NR系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。接入网设备14是一种部署在接入网12中用以为终端设备13提供无线通信功能的装置。接入网设备14可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备13提供无线通信功能的装置统称为接入网设备。The access network 12 includes several access network devices 14. The access network in the 5G NR system can be called NG-RAN (New Generation-Radio Access Network). The access network device 14 is a device deployed in the access network 12 to provide wireless communication functions for the terminal device 13. The access network device 14 can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in the 5G NR system, In the system, it is called gNodeB or gNB. With the evolution of communication technology, the name of "access network device" may change. For the convenience of description, in the embodiment of the present application, the above-mentioned device that provides wireless communication function for the terminal device 13 is collectively referred to as access network device.

终端设备13的数量通常为多个，每一个接入网设备14所管理的小区内可以分布一个或多个终端设备13。终端设备13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，上面提到的设备统称为终端设备，即本申请实施例中提到的终端设备与UE可以理解为同一含义。接入网设备14与核心网设备之间通过某种空中技术相互通信，例如5G NR系统中的NG接口。接入网设备14与终端设备13之间通过某种空中技术互相通信，例如Uu接口。The number of terminal devices 13 is usually multiple, and one or more terminal devices 13 can be distributed in each cell managed by an access network device 14. The terminal device 13 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile station (MS), etc. For the convenience of description, the above-mentioned devices are collectively referred to as terminal devices, that is, the terminal devices and UE mentioned in the embodiments of the present application can be understood as the same meaning. The access network device 14 and the core network device communicate with each other through some air technology, such as the NG interface in the 5G NR system. The access network device 14 and the terminal device 13 communicate with each other through some air technology, such as the Uu interface.

终端设备13和终端设备13(例如车载设备与其它设备(如其它车载设备、手机、RSU(Road Side Unit，路侧单元)等))之间可以通过直连通信接口(如PC5(ProSe Communication 5，近邻通信第五接口)接口)互相通信，相应地，该基于直连通信接口建立的通信链路可以称为直连链路或SL(SideLink，侧行链路)。SL传输即为终端设备与终端设备之间通过侧行链路直接进行通信数据传输，不同于传统的蜂窝系统中通信数据通过接入网设备接收或者发送，SL传输具有时延短、开销小等特点，适合用于地理位置接近的两个终端设备(如车载设备和地理位置接近的其它周边设备)之间的通信。需要说明的是，在图1中，仅以V2X(vehicle to everything，车联网)场景下的车对车通信为示例，SL技术可以应用于各种终端设备之间直接进行通信的场景。或者说，本申请中的终端设备是指任意一种利用SL技术通信的设备。Terminal devices 13 and terminal devices 13 (for example, vehicle-mounted devices and other devices (such as other vehicle-mounted devices, mobile phones, RSU (Road Side Unit), etc.)) can communicate with each other through a direct communication interface (such as PC5 (ProSe Communication 5, neighbor communication fifth interface) interface). Accordingly, the communication link established based on the direct communication interface can be called a direct link or SL (SideLink). SL transmission is the direct communication and data transmission between terminal devices through a side link. Unlike the traditional cellular system in which communication data is received or sent through an access network device, SL transmission has the characteristics of short delay and low overhead, and is suitable for communication between two terminal devices with close geographical locations (such as vehicle-mounted devices and other peripheral devices with close geographical locations). It should be noted that in Figure 1, only the vehicle-to-vehicle communication in the V2X (vehicle to everything) scenario is taken as an example. SL technology can be applied to scenarios where various terminal devices communicate directly with each other. In other words, the terminal device in this application refers to any device that communicates using SL technology.

The technical solution described in the embodiment of the present application may be applicable to a 5G NR system or to a subsequent evolution system of the 5G NR system.

在介绍本申请技术方案之前，先对本申请涉及的一些背景技术知识进行介绍说明。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。Before introducing the technical solution of this application, some background technical knowledge involved in this application is first introduced and explained. The following related technologies can be combined arbitrarily with the technical solution of the embodiment of this application as optional solutions, and they all belong to the protection scope of the embodiment of this application. The embodiment of this application includes at least part of the following contents.

在5G NR中，引入了上行链路切换(即所谓的超级上行)的功能。引入该功能旨在提供上行频段组合的上行发射性能，包括EN-DC(E-UTRA-NR Dual Connectivity，E-UTRA与NR双连接)、CA(Carrier Aggregation，载波聚合)和SUL(Supplementary Uplink，补充的上行链路)。该功能可以通过上行链路切换实现高低频相互配合，即当高频载波上行覆盖不足时切换到低频载波来提高上行覆盖能力，当上行覆盖充足时，利用高频载波的大带宽和MIMO(Multiple-Input Multiple-Output，多输入多输出)技术实现高速率传输。目前标准中仅支持两个频段之间的上行切换，UE一般会上报自身的能力，包括在哪两个频段上能支持上行链路切换、切换周期和下行中断所在的频段等。具体地，上行链路切换场景分别如图2与图3所示。如图2所示的上行链路切换场景中，情况1与情况3之间可以互相切换，情况2与情况3之间可以互相切换。情况1切换至情况3，即情况1中两条链路处于不同的载波上(载波#1、载波#2)，其中一条链路发生了链路切换，切换至情况3两条链路处于相同载波(载波#2)上。如图3所示的上行链路切换场景中，情况1、情况2和情况3之间均可以互相切换。情况1切换至情况2，即情况1中两条链路处于不同的载波上(载波#1、载波#2/#3)，其中一条链路发生了链路切换，切换至情况2两条链路处于相同载波(载波#1)上。In 5G NR, the function of uplink switching (the so-called super uplink) is introduced. The introduction of this function aims to provide uplink transmission performance of uplink frequency band combinations, including EN-DC (E-UTRA-NR Dual Connectivity), CA (Carrier Aggregation) and SUL (Supplementary Uplink). This function can achieve high-low frequency coordination through uplink switching, that is, when the uplink coverage of the high-frequency carrier is insufficient, switch to the low-frequency carrier to improve the uplink coverage capability. When the uplink coverage is sufficient, the large bandwidth of the high-frequency carrier and MIMO (Multiple-Input Multiple-Output) technology are used to achieve high-speed transmission. At present, the standard only supports uplink switching between two frequency bands. The UE generally reports its own capabilities, including which two frequency bands can support uplink switching, the switching period, and the frequency band where the downlink interruption is located. Specifically, the uplink switching scenarios are shown in Figures 2 and 3 respectively. In the uplink switching scenario shown in Figure 2, cases 1 and 3 can switch to each other, and cases 2 and 3 can switch to each other. Case 1 switches to case 3, that is, in case 1, the two links are on different carriers (carrier #1, carrier #2), one of the links undergoes link switching, and in case 3, the two links are on the same carrier (carrier #2). In the uplink switching scenario shown in Figure 3, cases 1, 2, and 3 can all switch to each other. Case 1 switches to case 2, that is, in case 1, the two links are on different carriers (carrier #1, carrier #2/#3), one of the links undergoes link switching, and in case 2, the two links are on the same carrier (carrier #1).

一般情况下，终端设备在进行上行链路切换时，由于两条链路的载波频率较近或存在谐波等干扰或共用部分器件等潜在原因，当一条链路发生切换时会对另一链路产生干扰。对于具有较低能力的终端，没有切换或切换过程完成的链路在另一条链路发生切换时一般都不进行传输，这样可以有效地降低两条链路之间的干扰，但同时也降低了系统吞吐量。对于具有较强能力的终端，可以在一条链路发生切换时保证另一条链路可以正常传输，从而提高系统的吞吐量。该能力需要终端上报给网络。由于两条链路无法保证同时进行切换，两条链路的切换时间可能会有重叠，因此对其中一条链路产生影响的时间间隔并不总是另一条链路的切换时间。当该时间间隔指示不准确时，会导致两条链路间的潜在干扰或上行性能下降。若该时间间隔过短，则会导致两条链路间的潜在干扰。若该时间间隔指示过长，则会导致上行吞吐量下降。因此当两条链路均发生切换时，如何准确指示该时间间隔是亟待解决的问题。Generally, when a terminal device switches uplink, due to potential reasons such as the close carrier frequencies of the two links or the presence of interference such as harmonics or the sharing of some components, when one link switches, it will interfere with the other link. For terminals with lower capabilities, the link that has not switched or the switching process is completed is generally not transmitted when the other link switches, which can effectively reduce the interference between the two links, but also reduce the system throughput. For terminals with stronger capabilities, when one link switches, the other link can be guaranteed to transmit normally, thereby improving the system throughput. This capability needs to be reported by the terminal to the network. Since the two links cannot be guaranteed to switch at the same time, the switching time of the two links may overlap, so the time interval that affects one link is not always the switching time of the other link. When the time interval is not accurately indicated, it will cause potential interference between the two links or degradation of uplink performance. If the time interval is too short, it will cause potential interference between the two links. If the time interval is too long, it will cause a decrease in uplink throughput. Therefore, when both links switch, how to accurately indicate the time interval is an urgent problem to be solved.

多频段(3band及以上)上行链路切换中两条链路均发生切换的场景包括：Scenarios where both links are switched in multi-band (3band and above) uplink switching include:

1.single band(单频段)与inter-band CA(频段间CA)之间切换，两条链路均发生切换，例如A+A<->B+C，即由单频段A切换至多频段B和C。1. Switching between single band and inter-band CA, both links are switched, for example, A+A<->B+C, that is, switching from single-band A to multi-band B and C.

2.inter-band CA与inter-band CA之间切换，无相同频段，两条链路均发生切换，例如A+B<->C+D，即由多频段A、B切换至多频段C、D。2. When switching between inter-band CA and inter-band CA, there is no identical frequency band and both links are switched, for example, A+B<->C+D, that is, switching from multi-band A and B to multi-band C and D.

根据不同的切换时间位置，多频段(3band及以上)上行链路切换中两条链路均发生切换可分为以下3种情况(包括相同切换时间长度与不同切换时间长度，示意图中以不同切换时间长度为例)：According to different switching time positions, the switching of both links in multi-band (3band and above) uplink switching can be divided into the following three situations (including the same switching time length and different switching time lengths, and the diagram takes different switching time lengths as an example):

情况1：一条链路的切换时段包含另一条链路的切换时段 Case 1: The switching period of one link includes the switching period of another link

如图4所示，第二上行链路的切换时段被第一上行链路的切换时段包含，即第二上行链路的切换时段的起始时刻和结束时刻位于第一上行链路的切换时段内。在一个示例中，第二上行链路的切换时段的起始时刻与第一上行链路的切换时段的起始时刻重合，第二上行链路的切换时段的结束时刻与第一上行链路的切换时段的结束时刻不重合，如图4子图a所示。在另一个示例中，第二上行链路的切换时段的起始时刻与第一上行链路的切换时段的起始时刻不重合，第二上行链路的切换时段的结束时刻与第一上行链路的切换时段的结束时刻不重合，如图4子图b所示。在另一个示例中，第二上行链路的切换时段的起始时刻与第一上行链路的切换时段的起始时刻不重合，第二上行链路的切换时段的结束时刻与第一上行链路的切换时段的结束时刻重合，如图4子图c所示。在另一个示例中，第二上行链路的切换时段与第一上行链路的切换时段完全重合，第二上行链路的切换时段的起始时刻与第一上行链路的切换时段的起始时刻重合，第二上行链路的切换时段的结束时刻与第一上行链路的切换时段的结束时刻也重合，即如图4子图d所示。As shown in Figure 4, the switching period of the second uplink is included in the switching period of the first uplink, that is, the starting time and the ending time of the switching period of the second uplink are located within the switching period of the first uplink. In one example, the starting time of the switching period of the second uplink coincides with the starting time of the switching period of the first uplink, and the ending time of the switching period of the second uplink does not coincide with the ending time of the switching period of the first uplink, as shown in sub-figure a of Figure 4. In another example, the starting time of the switching period of the second uplink does not coincide with the starting time of the switching period of the first uplink, and the ending time of the switching period of the second uplink does not coincide with the ending time of the switching period of the first uplink, as shown in sub-figure b of Figure 4. In another example, the starting time of the switching period of the second uplink does not coincide with the starting time of the switching period of the first uplink, and the ending time of the switching period of the second uplink coincides with the ending time of the switching period of the first uplink, as shown in sub-figure c of Figure 4. In another example, the switching period of the second uplink completely overlaps with the switching period of the first uplink, the starting moment of the switching period of the second uplink overlaps with the starting moment of the switching period of the first uplink, and the ending moment of the switching period of the second uplink overlaps with the ending moment of the switching period of the first uplink, as shown in sub-figure d of Figure 4.

情况2：两条链路非同时切换，且两条链路的切换时段有重叠，但其中一条链路的切换时段不被另一条链路的切换时段包含Case 2: The two links are switched non-simultaneously, and the switching periods of the two links overlap, but the switching period of one link is not included in the switching period of the other link.

如图5所示，第一上行链路的切换时段与第二上行链路的切换时段之间存在重叠，且第二上行链路的切换时段未被第一上行链路的切换时段包含。在一个示例中，第二上行链路的切换时段的起始时刻位于第一上行链路的切换时段内，第二上行链路的切换时段的结束时刻位于第一上行链路的切换时段的结束时刻之后，且第二上行链路的切换时段的起始时刻与第一上行链路的切换时段的起始时刻不重合，如图5子图a所示。在另一个示例中，第二上行链路的切换时段的起始时刻位于第一上行链路的切换时段的起始时刻之前，第二上行链路的切换时段的结束时刻位于第一上行链路的切换时段之内，且第二上行链路的切换时段的结束时刻与第一上行链路的切换时段的结束时刻不重合，如图5子图b所示。As shown in Figure 5, there is an overlap between the switching period of the first uplink and the switching period of the second uplink, and the switching period of the second uplink is not included in the switching period of the first uplink. In one example, the starting time of the switching period of the second uplink is within the switching period of the first uplink, the ending time of the switching period of the second uplink is after the ending time of the switching period of the first uplink, and the starting time of the switching period of the second uplink does not coincide with the starting time of the switching period of the first uplink, as shown in sub-figure a of Figure 5. In another example, the starting time of the switching period of the second uplink is before the starting time of the switching period of the first uplink, the ending time of the switching period of the second uplink is within the switching period of the first uplink, and the ending time of the switching period of the second uplink does not coincide with the ending time of the switching period of the first uplink, as shown in sub-figure b of Figure 5.

情况3：两条链路非同时切换且切换时段无重叠Case 3: The two links are switched non-simultaneously and the switching periods do not overlap

如图6所示，第一上行链路的切换时段与第二上行链路的切换时段不存在重叠。在一个示例中，第一上行链路的切换时段的结束时刻位于第二上行链路的切换时段的起始时刻之前，如图6子图a所示。在另一个示例中，第一上行链路的切换时段的起始时刻位于第二上行链路的切换时段的结束时刻之后，如图6子图b所示。As shown in Figure 6, there is no overlap between the switching period of the first uplink and the switching period of the second uplink. In one example, the end time of the switching period of the first uplink is before the start time of the switching period of the second uplink, as shown in sub-figure a of Figure 6. In another example, the start time of the switching period of the first uplink is after the end time of the switching period of the second uplink, as shown in sub-figure b of Figure 6.
