  • Figure 13a and Figure 13b are schematic diagrams of interference between NR and SL in the UE. As shown in Figure 13a, it is the interference situation when the SL timing of the terminal is aligned with the NR UE Rx signal, wherein the NR UE Tx signal is within the range of U1, and the SL Rx signal within the range of SL2 will not cause interference, and U1 and SL2 have time lengths equal to TA.
  • NR and SL work at the same time, and the terminal adopts NR and SL independent radio frequency architecture to increase the isolation between NR UE Tx signal and SL Rx signal and reduce interference, as shown in Figure 14b.
  • the magnitude of the interference depends on two factors, the transmit power of the NR UE Tx signal and the isolation between the NR UE Tx signal and the SL Rx signal.

Inhibition of leakage. Usually these factors have a lot to do with the implementation of the UE.
  • Scheme 1 The terminal reports that NR and SL work in the same frequency band at the same time, and the required minimum spectrum interval Gap_min between the NR UE Tx signal and the SL Rx signal.
  • This minimum spectrum spacing can correspond to the minimum spectrum spacing when the NR UE Tx signal is transmitted with the maximum power and does not cause interference of the SLRx signal, or the minimum spectrum spacing when the interference received by the SL Rx signal does not exceed XdB when the NR UE Tx signal is transmitted with the maximum power. .

  • the base station does not configure the alternate working time template of the NR UE Tx signal and the UE SL Rx signal, but allows the UE SL Rx signal of the UE to have a certain sensitivity deterioration.
  • Option 2 When the spectral positions of the NR UE Tx signal and the UE SL Rx signal are fixed, the terminal reports the maximum power capability Px that the terminal NR UE Tx signal can transmit when the sensitivity of the UE SL Rx signal is degraded by XdB.
  • the sensitivity deterioration XdB can be a value of 0 or greater than 0. This value can be a predefined value (only Px needs to be reported at this time), or it can be a value jointly reported by the terminal (XdB, Px)

  • Scheme 2 can inform the network of the scheduling limit of NR transmit power when the base station is difficult to coordinate the spectrum, that is, the relationship between the transmit power of the NR UE Tx signal and the sensitivity deterioration of the SL Rx signal, so that the network can not cause excessive SL Rx signal.

  • Example 2 UE SL Tx signal interference to NR gNB Rx signal
  • FIG 16 is a schematic diagram of UE SL Tx signal interfering with gNB Rx signal.
  • the transmission of the terminal SL will also interfere with the uplink reception of the base station. Due to the propagation delay between the terminal and the gNB, in the scenario of Figure 17a, the Tx signals of SL and SL1 will interfere with the reception of the U2 and U time slots of the gNB; in the scenario of Figure 17b, the Tx signal of SL will interfere with the U time of the gNB. slot reception.
  • the transmit power of the SL may be limited.
  • the SL transmit power control is open-loop power control, that is, the SL transmit power is calculated based on preconfigured parameters (eg, target power, propagation loss weight).
  • the propagation loss is that the propagation loss between the SL terminals is related to the distance between the SL terminals, but has nothing to do with the distance between the terminal and the base station. This also causes the terminal to transmit relatively large power even when it is very close to the base station, causing interference of the UE SL Tx signal to the gNB Rx signal.
  • the power control mechanism of this example may limit the SL power. To this end, it is necessary to consider limiting the transmit power of SL UEs that are relatively close to the base station to reduce the reception interference to the gNB. As shown in Figure 18, it is a schematic diagram of the interference of UE SL Tx in different areas to the base station.
  • the Pmax configuration based on geographic location (Pmax only works in some locations) can be adopted as follows:
  • Pmax is usually used to limit the maximum transmit power of UEs in a cell, and in a single-cell scenario, the transmit power of all UEs in a cell will be limited after this parameter is configured. This actually cannot meet the above requirements, that is, the goal is that Pmax will only work when the SL UE is at a relatively close distance from the base station. Based on this, the specific implementation is as follows:
  • a cell is divided into a plurality of grid areas according to geographic locations, and the information of the grid areas may be predefined.
  • the terminal and the base station can clearly obtain their own positions, for example, in Figure 19, the base station is located in grid 5.
  • the base station configures different Pmax values according to different grid areas where the terminal is located. For example, in Figure 19, the dark areas (identified as 1 to 9) closer to the base station are configured with a Pmax1 to limit the UE's transmit power to a lower power value. The light-colored areas (identified as 10 to 25) configure another Pmax2 to limit the UE transmit power to another power value. In the white area (marked as 26 to 49) far from the base station, the interference of the terminal SL transmission to the base station is not obvious, so this area does not need to limit the transmission power of the terminal.
  • Pmax can correspond to the identification of the grid area, such as ⁇ Pmax1, grid 1/2/3/4/5/6/7/8/9 ⁇ , ⁇ Pmax2, grid 10- 25 ⁇
  • the base station may carry the following information at the same time when broadcasting Pmax:
  • the distance requirement may be predefined without broadcasting.
  • the distance between the cell and the base station is divided into three regions ⁇ Distance1, Distance1 to Distance2, >Distance2, and three Pmax values ⁇ Pmax1, Pmax2, Pmax3 ⁇ are broadcast.
  • Pmax1 corresponds to the area of ⁇ Distance1
  • Pmax2 corresponds to the area of Distance1 to Distance2
  • Pmax3 corresponds to the area of >Distance2.
  • the distance requirement can also be broadcasted by the base station as required, to limit the use range of different Pmax.
  • the terminal After obtaining the longitude and latitude position information of the base station, the terminal can obtain the actual distance DistanceUE from the base station in combination with its own longitude and latitude information, and limit the transmit power based on the Pmax and distance requirements broadcast by the base station. For example:
  • the above-mentioned location-based Pmax broadcast can effectively solve the problem of interference to the gNB Rx signal when the SL terminal is located in the center of the cell and transmits high power.
  • the interference of the NR Tx in the UE to the UE SL Rx when the NR and SL are in the same frequency band can be solved, and the interference of the UE SL Tx to the gNB Rx can also be solved.

Description

通信方法、终端设备和网络设备 技术领域
本申请涉及通信领域，更具体地，涉及一种通信方法、终端设备和网络设备。
背景技术
当前的移动通信多是以基站为中心的，所有UE(User Equipment，用户设备)在空口都会与基站进行直接连接，并通过基站的中转找到目标UE进行通信。这种通信的好处是UE在网络中的行为是可控的，基站充当了控制中心的角色。在一些新兴的应用如D2D(Device to Device，设备到设备)通信或V2X(Vehicle to everything，车联网)中，UE可以直接与其他UE通信而不经过基站。这种UE与UE间的直接通信模式叫做SL(Sidelink，侧行)通信。侧行通信的特点是基站不再是控制中心，且可以在没有网络的情况下进行直接通信。UE的SL通信与NR通信之间可能存在干扰，UE的SL通信对基站也可能存在干扰，需要减少干扰。

图3a和图3b为SL通信场景的示意图。如图3a所示，当UE处于移动通信网络覆盖内场景时，UE通常会与NR基站保持连接，同时也会与其他UE保持SL连接。如图3b所示，当UE处于移动通信网络覆盖外场景时，UE通常不在NR基站的覆盖区域，UE仅存在SL连接。
下面介绍关于收发定时的内容。
在通信系统中，基站端具有严格的定时。图4为基站及UE定时的示意图。如图4所示，基站gNB定时(timing)是从基站端看到的收发定时。
由于终端与基站之间具有一定的距离，导致基站发射的信号会经过一定时间的传播延迟而被UE接收，体现在UE侧就是，UE接收时间相比gNB timing具有一个时延。在图4中，下行定时(downlink timing，DL)(UE)整体比gNB timing往后进行了偏移。
为了避免同一小区内的多个UE发射的上行信号到达基站的时间不一致从而造成相互干扰，基站需要对UE的发射时间视其距离进行调整。距离远的UE相比距离近的UE需要更早的提前发射，从而到达基站端的信号相互之间是差不多同时到达的。如图4所示，上行定时(uplink timing)(UE)会比gNB timing及downlink timing(UE)都提前了一定时间。通常将downlink timing(UE)与uplink timing(UE)间的定时提前称为TA(Timing advance)。
对比没有TA和有TA情况下基站及终端收发信号的定时差异。可以得出，在没有TA情况下，基站收到的不同UE发射的上行信号在时间上处于分散的状态，而采用TA后不同UE发射的上行信号在基站端是几乎同时到达的。
下面介绍关于SL的收发定时及干扰
在SL通信中，当UE处于NR小区(或称为NR基站)覆盖范围内时，包括两种SL定时的示例：
图5为SL定时与NR UE Rx定时对齐场景下的干扰的示意图。如图5所示(灰色表示工作时隙)，例如，SL与UE Rx(接收)定时保持一致，且SL只能工作在上行发射时隙。这样导致UE的发射定时(Tx)会与SL的定时存在一个定时偏差TA。在这种定时结构中，当UE的NR与SL工作在同一频段时，NR发射信号干扰SL接收信号(例如，干扰SL+SL1)，并且SL的发射信号(例如SL+SL1)也将干扰基站的接收信号。
注：SL2不受NR发射的影响，也不会影响NR基站的接收
图6为SL定时与NR UE Tx定时对齐场景下的干扰的示意图。如图6所示(灰色表示工作时隙)，例如，SL与UE发射(Tx)定时保持一致，且SL只能工作在上行发射时隙。这样导致UE的发射(Tx)定时会与SL的定时保持一致。在这种定时结构中，当NR与SL工作在同一频段时，NR发射信号干扰SL接收信号，同时SL的发射信号也将干扰基站的接收信号
针对以上SL定时模式下的涉及NR与SL的干扰，本申请实施例可以提供多种方案。
图7是根据本申请一实施例通信方法200的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。

可选地，在本申请实施例中，该方法还包括：
在该NR上行信号与该SL接收信号之间的频谱间隔小于该频谱间隔要求例如最小频谱间隔的情况下，如果该终端设备同时进行该NR上行信号的发射和该SL接收信号的接收，则该终端设备的SL接收灵敏度恶化。
示例性地，如果该NR上行信号与该SL接收信号之间实际的频谱间隔小于该最小频谱间隔，并且终端设备的NR上行信号的发射和SL接收信号的接收同时进行，这种情况下，可以允许终端设备的SL接收灵敏度恶化。并且，还可以按照一定的恶化值控制终端设备的SL接收灵敏度恶化。

可选地，在本申请实施例中，该频谱间隔要求包括以下至少之一：
使得该NR上行信号以最大功率发射且不引起该SL接收信号干扰的最小频谱间隔；
使得该NR上行信号以最大功率发射且该SL接收信号收到的干扰不超过设定值的最小频谱间隔。
可选地，在本申请实施例中，该方法还包括：
在该NR上行信号与该SL接收信号之间的频谱间隔小于该频谱间隔要求例如最小频谱间隔的情况下，该网络设备发送该NR上行信号和该接收SL接收信号的轮流工作时间模板。该时间模板可以规定NR上行信号的发射和SL接收信号的接收不同时进行的具体方式。例如，按照时隙轮流地进行NR上行信号的发射和SL接收信号的接收。

采用标准预定义该恶化值；
接收该终端设备上报的该恶化值。
本实施例的网络设备执行方法300的具体示例可以参见上述方法200的中关于网络设备例如基站的相关描述，为了简洁，在此不再赘述。
在本实施例中，网络设备收到终端设备上报的频谱间隔要求例如最小频谱间隔后，可以在调度载波频谱时尽量采用较大的频谱间隔来规避干扰。
图9是根据本申请另一实施例通信方法400的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。
S410、终端设备上报引起侧行链路SL接收灵敏度恶化的恶化值对应的新无线NR上行信号的最大功率能力。
在本申请实施例中，在终端设备内部，从该终端设备向网络设备发送的信号可以称为NR上行信号，该终端设备从另一终端设备接收的信号可以称为SL接收信号。终端设备向网络设备上报引起SL接收灵敏度恶化的恶化值对应的NR上行信号的最大功率能力，网络设备可以根据该最大功率能力，调度该 终端设备的NR上行信号和SL接收信号，使得终端设备的NR上行信号的发射功率尽可能小于或等于该最大功率能力。这样，通过上报该恶化值对应的NR上行信号的最大功率能力，使得网络设备能够在不引起过大SL接收信号的性能损失的情况下，调度NR上行信号的发射功率，减少SL接收信号与NR上行信号之间的干扰。
可选地，在本申请实施例中，该方法还包括：该终端设备上报该恶化值。具体地，该终端设备可以将恶化值与最大功率能力联合上报，也可以分别上报。网络设备可以根据该最大功率能力，调度该终端设备的NR上行信号和SL接收信号，使得终端设备的NR上行信号的发射功率尽可能小于或等于该终端设备实际的恶化值对应的最大功率能力。这样，通过上报该恶化值及其对应的NR上行信号的最大功率能力，使得网络设备能够在不引起过大SL接收信号的性能损失的情况下，调度NR上行信号的发射功率，减少SL接收信号与NR上行信号之间的干扰。
可选地，在本申请实施例中，该恶化值为预定义的值。例如，在终端设备和网络设备分别保存终端设备的最大功率能力与该恶化值的对应关系。
可选地，在本申请实施例中，该方法还包括：该终端设备在发射功率超出该最大功率能力和该恶化值超出阈值满足至少之一的情况下，断开NR连接和/或断开SL连接。该恶化值的阈值与最大功率能力有间接的关系。基站可以根据自身能接受的终端灵敏度恶化值对应的发射功率能力来调度UE的发射功率，但阈值的确定与最大功率没有直接关系，而可以是根据灵敏度恶化情况来确定。
示例性地，如果终端设备实际的发射功率超出该最大功率能力，并且，终端设备的SL接收灵敏度恶化实际的恶化值超出阈值，则终端设备可以断开与网络之间的NR连接，也可以断开与其他终端设备的SL连接，还可以断开NR连接和SL连接。

在本实施例中，网络设备发送该网络设备允许的终端设备的最大发射功率，该发射功率要求与位置信息关联，可以使得终端设备将自身的发射功率限定为小于该最大发射功率，从而减少终端设备发送功率过大对网络设备造成的干扰。
在本申请实施例的应用示例中，可以解决在NR和SL同频段工作时，终端内部NR UE Tx信号(也可以称为NR上行信号，也可以简称NR Tx信号)对UE SL Rx信号(也可以称为SL接收信号，也可以简称SL Rx信号)的干扰的问题。参见以下方案1和/或方案2：
方案1：终端上报可支持的NR与SL同频段下同时工作的最小频谱间隔。
方案2：终端上报NR UE Tx信号的发射功率与SL Rx信号性能恶化的对应关系。
在本申请实施例的应用示例中，还可以解决UE的SL Tx信号对网络设备例如gNB Rx信号(也可以称为网络接收信号)的干扰的问题。参见方案3。
方案3：基站基于位置的Pmax广播方式，Pmax为该基站允许的终端的最大发射功率。
在SL和NR处于同一频段的情况下，为规避干扰如果采用时分方式无法同时工作，带来的是整体性能的下降。本申请实施例中，方案1上报终端能力可以实现SL与NR在同一频段下的同时工作，减少干扰，提升终端性能。方案2上报恶化的信息可以通过基站对UE发射功率的控制来将干扰维持在一定范围内。方案3基站基于地理位置的Pmax限制终端的最大发射功率，可以降低的对基站端的干扰，提升基站的性能。
下面分别介绍各个方案的具体示例。
示例1：UE内部NR UE Tx信号对SL Rx信号的干扰
图13a和图13b UE内部NR对SL的干扰示意图。如图13a所示，为当终端的SL定时与NR UE Rx信号对齐时的干扰情况，其中，NR UE Tx信号在U1范围内，以及SL Rx信号在SL2范围内不会带来干扰，且U1和SL2的时间长度均等于TA。如图13b所示，为当终端SL Rx信号定时(可以简称SL定时)与NR UE Tx信号对齐时的干扰情况，其中的两个U时隙与两个SL时隙重叠(即UE NR Tx与UR SL Rx同时工作)，并存在NR UE Tx信号对SL Rx信号的干扰。
如图14a和图14b所示，当NR与SL工作于同一个频段时，在终端实现架构上，可以采用共射频 链路或采用独立射频链路两种情况。
对于采用共射频链路架构，NR与SL之间没有链路间的隔离，因此在同时工作的情况下会带来严重的干扰。对于这种情况，多采用时分模式(轮流工作)来规避干扰，但性能会受影响。
因此，更多时候，NR与SL同时工作，同时终端采用NR与SL独立射频架构以增加NR UE Tx信号与SL Rx信号间的隔离度，降低干扰，如图14b所示。
干扰的大小取决于两个因素，NR UE Tx信号的发射功率强度、NR UE Tx信号与SL Rx信号间的隔离度。其中隔离度的大小(如图15所示)又取决于NR UE Tx信号工作频谱与SL Rx信号频谱的间距、NR UE Tx信号频谱的带外泄露强度、SL Rx信号对NR UE Tx信号带外泄露的抑制度。通常这些因素与UE的实现有很大关系。在同样的频谱间距下，NR带外泄露越小、SL Rx信号对NR UE Tx信号带外泄露抑制度越大，则干扰越小。而对于同一个UE来说，NR UE Tx信号频谱与SL Rx信号频谱间距越大则干扰越小。
基于以上分析，为解决当NR与SL工作于同一频段时NR UE Tx信号对SL Rx信号的干扰，可通过以下方式进行：
方案一：终端上报NR与SL在同一频段同时工作，所要求的NR UE Tx信号与SL Rx信号间的最小频谱间隔Gap_min。
这个最小频谱间隔可以对应NR UE Tx信号最大功率发射且不引起SL Rx信号干扰的最小频谱间隔，或者对应NR UE Tx信号最大功率发射时SL Rx信号收到的干扰不超过XdB时的最小频谱间隔。
当NR UE Tx信号与UE SL Rx信号间的频谱间隔小于最小频谱间隔能力Gap_min时，终端SL Rx将受到较强的干扰，可进一步采取以下处理方式：
方式1、终端NR UE Tx信号和UE SL Rx信号不同时进行，即采用TDD模式
方式2、终端NR UE Tx信号和UE SL Rx信号同时进行，但允许UE SL Rx信号采取一定的灵敏度恶化。该灵敏度恶化的恶化值可以是标准预定义的，也可以是终端上报的一个能力指示信息。
基站收到上述最小频谱间隔能力Gap_min后，参考该Gap_min值进行NR UE Tx信号和SL Rx信号频谱的使用调度。
当实际调度的频谱间隔小于Gap_min时：
基站可选择采用上述方式1进行处理。这种情况下，基站需要给UE配置NR UE Tx信号(简称NR Tx)和SL UE Rx信号(简称SL Rx)的轮流工作时间模板(TDD pattern)，举例如下：
NR Tx SL Rx NR Tx SL Rx NR Tx SL Rx NR Tx SL Rx NR Tx SL Rx
基站也可以采用上述方式2进行处理。这种情况下，基站不配置NR UE Tx信号和UE SL Rx信号的轮流工作时间模板，但允许UE的UE SL Rx信号有一定的灵敏度恶化。
方案二：在NR UE Tx信号和UE SL Rx信号频谱位置一定的情况下，终端上报引起UE SL Rx信号灵敏度恶化XdB时，终端NR UE Tx信号可发射的最大功率能力Px。其中灵敏度恶化XdB可以为0或大于0的数值，该数值可以为预定义的值(此时只需要上报Px)，也可以是终端联合上报的值即(XdB，Px)
基站收到终端上报的NR UE Tx信号可发射最大功率能力Px及灵敏度恶化XdB后，基站参考该最大功率能力进行调度。当终端发射功率超过Px且灵敏度恶化X大于一预定值X_limit后，允许UE断掉NR连接或断掉SL连接。
在本示例中，为规避终端内NR UE Tx信号对SL Rx信号的干扰，给出了两种方案。方案一可以通过终端上报最小频谱间隔Gap来促使基站在调度载波频谱时尽量采用较大的频谱间隔来规避干扰。方案二可以在基站难以协调频谱的情况下，终端告知网络NR发射功率的调度限制，也即NR UE Tx信号发射功率与SL Rx信号灵敏度恶化的关系，这样网络能够在不引起过大SL Rx信号性能损失的情况下来调度NR UE Tx信号的发射功率。
通过以上方案，可以将终端内部NR UE Tx信号与SL Rx信号之间的干扰透明化，并通过基站辅助降低终端内干扰。
上述方案对于基站来说可以属于可选特性。
示例2：UE SL Tx信号对NR gNB Rx信号的干扰
图16为UE SL Tx信号干扰gNB Rx信号的示意图。如图16所示，终端SL发射也将干扰基站的上行接收。由于终端与gNB的传播时延，导致：在图17a场景中SL和SL1的Tx信号，将干扰gNB的U2和U时隙的接收；在图17b场景中SL的Tx信号将干扰gNB的U时隙的接收。
在上述场景下，为解决干扰可以对SL的发射功率进行限定。相关技术中SL发射功率控制为开环功率控制，也即SL发射功率是基于预配置的参数(例如目标功率、传播损耗加权)进行计算。其中传播损耗是SL终端间的传播损耗与SL终端间距离有关，而与终端与基站间的距离无关。这也导致了终端在离基站很近的情况下依然会发射比较大的功率，造成UE SL Tx信号对gNB Rx信号的干扰。
本示例的功率控制机制可以对SL功率进行限制。为此，需要考虑对距离基站比较近的SL UE的发射功率进行限制，来降低对gNB的接收干扰，如图18所示，为不同区域的UE SL Tx对基站的干扰示意图。
具体可以采用基于地理位置的Pmax配置(Pmax仅在部分位置下才起作用)方案如下：
Pmax通常被用来限定小区内的UE的最大发射功率，且对于单小区场景下配置该参数后小区内的所有UE的发射功率都会受限。这实际无法满足上述需求，也即目标是只有当SL UE处于距离基站比较近的距离时Pmax才会起作用。基于此，具体实现方式如下：
方式1、基于网格区域的Pmax广播
如图19所示，将小区按照地理位置划分为多个网格区域，该网格区域的信息可以是预定义的。终端和基站可以清晰获取自身的位置，例如，在图19中，基站位于网格5。
基站按照终端所处的不同网格区域配置不同的Pmax值。例如，在图19中，与基站较近的深色区域(标识为1至9)配置一个Pmax1来将UE的发射功率限制到一个较低的功率值。浅色区域(标识为10至25)配置另外一个Pmax2将UE发射功率限制到另外一个功率值。与基站较远的白色区域(标识为26至49)，终端SL发射对基站的干扰并不明显，则此区域并不需要对终端的发射功率进行限定。
在具体信令设计上，Pmax可以与网格区域的标识进行对应，例如{Pmax1，网格1/2/3/4/5/6/7/8/9}，{Pmax2，网格10-25}
因此，当终端进入白色区域时，可以按照常规功率进行SL发射。当终端进入浅色区域后，SL需要按照Pmax1控制发射功率。当终端进入深色区域，SL需要按照Pmax2控制发射功率。
方式2、基于地理位置的Pmax广播
在这种方式中，可以采用与方式1类似的方式，但不划分网格区域，而是基于距离限制发射功率。具体方式可以包括：基站在进行Pmax广播的时候可以同时携带以下信息：
(1)基站经纬度位置信息，因为基站位置信息是不变的，所以该信息可以是单独广播的来节省信令开销，也可以是和Pmax一起广播的。
(2)距离要求。
(2-1)该距离要求可以是预定义的而不需要广播。
例如将小区内与基站的距离划分为<Distance1，Distance1到Distance2，>Distance2三个区域，并广播三个Pmax值{Pmax1,Pmax2,Pmax3}。其中Pmax1对应<Distance1的区域，Pmax2对应Distance1到Distance2的区域，Pmax3对应>Distance2的区域。
(2-2)该距离要求也可以是基站根据需要而广播的，用来限定不同Pmax的使用范围。
例如{Pmax1,Distance1}、{Pmax2,Distance2}…(假设Distance1<Distance2<…)。
终端在获取到基站的经纬度位置信息后，结合自身的经纬度信息，可以得到与基站的实际距离DistanceUE，并基于基站广播的Pmax和距离要求来限制发射功率。例如：
当DistanceUE≤Distance1时，UE SL信号的最大发射功率不应超过Pmax1；
当Distance1<DistanceUE≤Distance2时，UE SL信号的最大发射功率不应超过Pmax2。
在本示例中，通过上述基于位置的Pmax广播，可以有效解决SL终端处于小区中心位置且发射大功率情况下带来的对gNB Rx信号的干扰问题。
通过以上技术方案，可解决NR和SL同频段时UE内NR Tx对UE SL Rx的干扰，还可以解决UE SL Tx对gNB Rx的干扰。
