  • Mode1 is a base station (evolved Node B, eNB) scheduling mode
  • mode 2 is a user equipment (User Equipment, UE) autonomously selecting resources.
  • UE User Equipment
  • V2X Sidelink (side link transmission) communication uses a sensing mechanism to reduce resource conflicts.
  • the user equipment working in mode2 is always in the resource-aware state, and candidate resources are determined to be used as the user equipment of the receiving UE.
  • the receiving UE When receiving the data packet sent by the sending UE, the receiving UE will perceive it according to the period of time before the data packet arrives.
  • Candidate resources then randomly select the next first transmission and subsequent multiple transmission resources from the candidate resources, and indicate this time in the SCI (Sidelink Control Infermation) of each transmission.
  • SCI Segmentlink Control Infermation
  • UE4 eliminates resources in the resource awareness window to determine the candidate resource set.
  • UE4 decodes the SCI of other UEs (such as UE1, UE2, UE3, UE5) to obtain resource reservations of other UEs Information, and do RSRP (Reference Signal Receiving Power, reference signal received power) measurement, if the interference is too strong, that is, the RSRP is higher than the preset threshold, it will be eliminated. If UE4 detects that the RSRP reserved by UE1 and UE5 is higher than the preset threshold, and the RSRP reserved by UE2 and UE3 is not higher than the preset threshold, UE4 excludes the resources reserved by UE1 and UE5 from the candidate resource set, and finally The remaining resources in the candidate resource set are the final candidate resources.
  • RSRP Reference Signal Receiving Power
  • UE4 will randomly select resources for transmission in the final candidate resource set in the selection window and indicate the resources used for this transmission of the same TB (transmission block) in the SCI of each transmission and the resources used for multiple subsequent transmissions. Resources and indicate the period of reserved resources for transmission of different TBs.
  • SCI is supported to reserve resources for up to three transmissions, and periodic reservation of resources is supported.
  • UEs near UE4 can receive UE4's resource reservation information when performing resource awareness.
  • UE1 and UE2 use unicast communication, the communication distance is 50m (meters), and the transmit power is 10dBm (decibel milliwatt).
  • UE3 and UE4 use unicast communication, the distance is 300m, and the transmit power is 23dBm. Assuming that UE3 selects a frequency domain resource adjacent to UE1, because UE3 has a larger transmit power, UE2 at the receiving end will receive interference from UE3, and the greater the transmit power gap, the greater the interference, which causes IBE (in-band transmission). )problem.
  • Figure 2 shows the hidden node problem under resource allocation mode2. Assuming that UE1 and UE2 use unicast communication, the distance is 50m, and the transmit power is 10dBm; UE1 and UE3 are far apart, and UE3 is outside the sensing range of UE1. UE3 and UE4 use unicast communication, the distance is 300m, and the transmit power is 23dBm. When UE1 senses resources, it does not know the frequency domain resources selected by UE3. If the same frequency domain resources as UE3 are selected and used at the same time, the two will collide, and UE2 cannot successfully receive the communication data of UE1.
  • the resource allocation mode 4 of LTE (Long Term Evolution) V2X is also a resource selection process based on UE perception. Therefore, under LTE V2X mode 4, there are also IBE problems.
  • UE1 and UE3 both use 23dBm transmit power to perform broadcast (broadcast) communication with UE2 and UE4 respectively. Assuming that UE1 and UE3 are far apart and adjacent resources are selected, then at the receiving end UE2, Will receive interference from UE3, and the closer the distance, the greater the interference will cause IBE problems.
  • Zone ID In LTE V2X mode 4, Zone ID (Zone ID) is used to divide the resource pool to solve the IBE problem.
  • UEs in different zones use mutually orthogonal frequency domain resources. Since UE1 and UE3 are far apart and belong to different zones, the resources used are also separated, thus solving the IBE problem.
  • LTE V2X mode 4 In LTE V2X mode 4, only broadcast communication is supported, and the transmission power of the UE is the same, which is the maximum transmission power. Therefore, the IBE problem only exists when the sending UE is far away from the interfering UE. Therefore, in LTE V2X mode 4, the zone ID can be used to divide the resource pool so that the sending UE and the interfering UE are divided into different zones to solve the IBE problem.
  • NR New Radio New Radio
  • V2X mode2 not only broadcast communication is supported, but also unicast communication and multicast communication are supported. Since unicast communication and multicast communication support adjusting the transmission power, the IBE problem not only exists in the same distance. In the case of transmit power, it still exists in the case of close distance but large gap between transmit and power, so the method of dividing the resource pool by zone ID cannot solve the IBE problem in NR V2X mode2, and NR V2X mode2 does not support the use The way in which the zone ID divides the resource pool.

Description

V2X通信中资源分配的处理方法、系统、设备及介质
本申请要求申请日为2020年2月18日的中国专利申请202010098781.8的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明涉及无线通讯领域，尤其涉及一种V2X通信中资源分配的处理方法、系统、设备及介质。
背景技术
随着无线通信技术的发展，其在越来越广泛的领域获得应用。例如，在车辆通信领域中，车辆外联(vehicle-to-everything，V2X)技术致力于实现高速设备之间，高速设备与低速设备之间，或高速设备与静止设备之间低时延高可靠性的通信。其中，X可以表示车辆、行人、道路设施、或网络等，即V2X可以包括车-车(vehicle-to-vehicle，V2V)通信、车-道路设施(vehicle-to-infrastructure，V2I)通信、车-行人(vehicle-to-pedestrian，V2P)通信、或车-网络(vehicle-to-network，V2N)通信等。
V2X技术是未来智能交通运输系统的关键技术，它使得车可以与外界进行通信，从而获得实时路况、道路信息、行人信息等一系列交通信息，从而提高驾驶安全性、减少拥堵、提高交通效率、提供车载娱乐信息等。
目前针对V2X的资源分配方式有两种模式，即mode1和mode2，mode1是基站(evolved Node B，eNB)调度方式，mode2是用户设备(User Equipment，UE)自主选择资源方式。其中，对于UE自主选择资源方式，UE按照一定规则自主地从资源池里面选择资源来传输，V2X Sidelink(侧链路传输)通信采用感知机制来降低资源冲突。
工作在mode2下的用户设备始终处于资源感知状态，并确定候选资源，用作接收UE的用户设备，在接收到发送UE发送的数据包时，接收UE会根据数据包到达之前的一段时间感知到候选资源，之后在候选资源中随机选择接下来的第一次传输和后续多次传输的资源，并在每一次传输的SCI(Sidelink Control Infermation，侧链路传输的控制信令)中指示本次传输所用的资源以及最多为后续的两次传输预留资源，并指示资源的预留周期。
假设当前通信范围内UE1-UE5在工作，假设UE4在时刻n有数据包到达，时间(n-t，n)作为资源感知窗口(其中t>0)，(n+T1，n+T2)时间段为资源选择窗口(其中T2>T1)，UE4在资源感知窗口内做资源排除以确定候选资源集，首先UE4解码其他UE(如UE1,UE2,UE3,UE5)的SCI，获得其他UE的资源预留信息，并做RSRP(Reference Signal Receiving Power，参考信号接收功率)测量，若干扰太强，即RSRP高于预设阈值就排除掉。假如UE4测得UE1和UE5预留的资源RSRP高于预设阈值，UE2和UE3预留的资源RSRP没有高于预设阈值，因此UE4在候选资源集中排除掉UE1和UE5预留的资源，最后候选资源集中剩余的资源即为最后的候选资源。UE4会在选择窗口内在最后的候选资源集中随机选择用于传输的资源并在每一次传输的SCI中指示同一个TB(transmission block，传输 块)的此次传输所用的资源以及后续多次传输的资源并指示预留资源的周期用于不同TB的传输。在mode2中，支持SCI为最多三次传输预留资源，并且支持资源的周期性预留。UE4附近的UE在做资源感知的时候都能收到UE4的资源预留信息。
如图1所示，UE1和UE2采用单播(unicast)通信，通信距离为50m(米)，发射功率为10dBm(分贝毫瓦)，UE3和UE4采用单播通信，距离为300m，发射功率为23dBm。假设UE3选择了与UE1邻近的频域资源，由于UE3的发射功率较大，在接收端UE2处会受到来自UE3的干扰，且发射功率差距越大，干扰越大，即造成IBE(带内发射)问题。
图2为资源分配mode2下的隐藏节点问题。假设UE1和UE2采用单播通信，距离为50m，发射功率为10dBm；UE1和UE3相距较远，UE3在UE1的感知范围外，UE3和UE4采用单播通信，距离为300m，发射功率为23dBm，UE1在感知资源的时候不知道UE3选择的频域资源，如果选择了和UE3相同的频域资源，且同时使用，则会造成两者发生碰撞，UE2不能成功接收UE1的通信数据。
现有技术中，LTE(Long Term Evolution)V2X的资源分配mode4也是UE基于感知的资源选择过程，所以在LTE V2X mode4下，也存在IBE问题。如图3所示，UE1和UE3均以23dBm的发射功率分别和UE2和UE4做broadcast(广播)通信，假设UE1和UE3距离较远，并选择了相邻的资源，则在接收端UE2处，会受到来自UE3的干扰，且距离越近干扰越大即造成IBE问题。
在LTE V2X mode4中，是采用Zone ID(区域ID)来划分资源池的方式解决IBE问题，不同的Zone内的UE使用相互正交的频域资源。由于UE1和UE3距离较远，属于不同的Zone，使用的资源也是分开的，从而解决了IBE问题。
在LTE V2X mode4中只支持广播通信，且UE的发射功率都相同，为最大的发射功率，所以IBE问题只存在于发送UE和干扰UE相距较远的情况。因此在LTE V2X mode4中，可以采用Zone ID划分资源池使发送UE和干扰UE划分在不同的Zone中来解决IBE问题。
但是在NR(New Radio新空口)V2X mode2中不仅支持广播通信还支持单播通信和组播通信，由于单播通信和组播通信支持调整发射功率，所以IBE问题不仅存在于距离较远的相同发射功率的情况下，还存在于相距较近但是发射和功率差距较大的情况下，所以采用Zone ID划分资源池的方法在NR V2X mode2中解决不了IBE问题，且NR V2X mode2中不支持采用Zone ID划分资源池的方式。
在V2X通信的资源分配mode2下，UE通过感知选择资源来完成V2V(vehicle to vehicle)通信，如果发送UE在感知选择资源的时候不知道接收UE侧的情况，接收UE侧可能存在IBE(In-Band-Emission)问题或者隐藏节点问题，从而导致接收UE不能在发送UE选择的资源上成功接收，且由于V2X mode2支持资源的周期性预留，可能会导致连续碰撞等冲突问题，造成发送、接收信息准确率低的缺陷。
