Definitions
- the present application relates to the field of wireless communication technologies, and in particular, to a method, a device, and a device for resource allocation and receiving resource allocation.
- LTE-V2X Long-Term Evolution-Vehicle
- the long-term evolution of 3GPP Release 14 and Release 15-Vehicle-to-Everything (LTE-V2X, Long-Term Evolution-Vehicle) through-link communication supports through-link transmission mode 3 and through-link transmission mode 4.
- the through-link transmission mode 3 is for the base station to allocate resources for terminal scheduling
- the through-link transmission mode 4 is for the user equipment (User Equipment, UE) to autonomously select resources.
- LTE-V2X pass-through communication of 3GPP Release14 and Release 15 only supports broadcast communication.
- 3GPP Release 14's through link transmission mode 4 supports the resource selection mechanism of sensing + semi-persistent scheduling (Sensing + SPS).
- the specific scheme is as follows:
- FIG. 1 is a schematic diagram of a time axis for selecting transmission resources on a LTE-V2X single carrier. As shown in the figure, currently, the selection of transmission resources on a LTE-V2X single carrier includes the following steps:
- Step1 Mark all candidate resources in the resource selection window as available
- Step2 Exclude occupied resources, including 2 types:
- the first type is that in the sensing window, the UE sends itself and cannot monitor the service packets sent by other UEs on the sending subframe.
- the above subframes become skipped subframes. It is necessary to assume that other UEs in the subframe use the system All the configured cycles reserve the next resource, and the reserved resource overlaps the candidate subframes, or overlaps with the 1, 2, ..., 10 * counter-1 transmission subframes after the candidate subframes.
- the second type is monitoring scheduling assignments (SA, Scheduling Assignment) sent by other UEs in the sensing window.
- SA Scheduling Assignment
- PSSCH-RSRP Physical Sidelink Shared Channel-Reference Received Signal Power
- step 2 If after step 2 is excluded, the remaining resource ratio is lower than 20%, increase the threshold by 3 dB, and re-execute the exclusion process until the remaining resource ratio reaches or exceeds 20%;
- Step3 Perform direct link-received signal strength indication (S-RSSI) measurement and ranking on candidate resources, select the 20% resource with the lowest S-RSSI measurement value, and the upper layer will start from the above 20% Resource selection is performed among candidate resources.
- S-RSSI direct link-received signal strength indication

- the sending resource causes the UE to fail to meet radio frequency (RF) requirements, for example, due to power spectral density imbalance (PSD imbalance, Power Spectrum Density imbalance)
- the UE performs resource selection independently for each carrier. If the result of resource selection results in simultaneous If the number of transmissions exceeds the sending capability of the UE, the resource selection process is performed again until the resource selection result can be supported by the UE.

本申请要求在2018年09月27日提交中国专利局、申请号为201811134092.7、申请名称为“一种资源分配及接收资源分配的方法、设备、装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及无线通信技术领域,特别涉及一种资源分配及接收资源分配的方法、设备、装置。
3GPP Release14和Release 15的长期演进-车到万物(LTE-V2X,Long Term Evolution-Vehicle to Everything)直通链路通信支持直通链路发送模式3和直通链路发送模式4。直通链路发送模式3为基站为终端调度分配资源,直通链路发送模式4为用户设备(User Equipment,UE)自主选择资源。3GPP Release14和Release 15的LTE-V2X直通链路通信仅支持广播通信。
3GPP Release14的直通链路发送模式4支持感知+半持续调度(Sensing+SPS,Sensing semi-persistent schedule)的资源选择机制,具体方案如下:
图1为LTE-V2X单载波上发送资源的选择时间轴示意图,如图所示,目前LTE-V2X单载波上发送资源的选择包括以下步骤:
Step1:将资源选择窗内的所有候选资源标记为可用;
Step2:进行已占用资源的排除,包括2类:
第一类是sensing窗口中,UE自身进行发送而无法在发送子帧上监听到其他UE发送的业务包,上述子帧成为未监听(skip)子帧,需要假定该子帧上其他UE以系统配置的所有周期均预约了下一次资源,且预约的资源与候选子帧交叠,或者与候选子帧之后的1,2,…,10*counter-1次发送子帧交叠, 需要将上述候选子帧排除;
第二类是在sensing窗口中监听到了其他UE发送的调度分配(SA,Scheduling Assignment,根据从SA中获知的周期和资源预约信息,如果预约的资源与候选资源交叠,或者与候选子帧之后的1,2,…,10*counter–1次发送资源交叠,且根据SA测量到的物理直通链路共享信道-参考信号接收功率(PSSCH-RSRP,Physical Sidelink Shared Channel-Reference Signal Received Power)高于的门限值,则相应的候选资源需要被排除;
如果step2排除后、剩余资源比例低于20%,则将门限值提升3dB,重新执行排除过程,直至剩余资源比例达到或高于20%为止;
Step3:对候选资源进行直通链路-接收的信号强度指示(S-RSSI,Sidelink-Received Signal Strength Indication)测量和排序,选择出S-RSSI测量值最低的20%资源,由高层从上述20%候选资源中进行资源选择。
3GPP Release15的直通链路发送模式4在3GPP Release14的Sensing+SPS的资源选择机制基础上,增加了多载波资源选择的处理,即:
高层为物理层提供候选资源池,物理层按照3GPP Release14的Sensing机制的step1和step2的资源排除,对候选资源进行S-RSSI测量和排序,选择出S-RSSI测量值最低的20%资源上报给高层,高层针对以下超出UE发送能力的子帧进行排除之后,选择出发送资源:
(a)发送链路(TX chains)的数量小于配置的发送载波数量;
(b)UE不能支持给定频带(band)的合并;
(c)TX chain切换时间。
如发送资源导致UE不能满足射频(Radio Frequency,RF)需求,例如由于功率谱密度不平衡(PSD imbalance,Power Spectral Density imbalance),UE对每个载波独立执行资源选择,如果资源选择的结果导致同时发送次数超过UE发送能力,则重新执行资源选择过程,直至资源选择结果可以被UE所支持。
现有技术的不足在于,3GPP Release14和Release 15的LTE-V2X直通链 路通信仅支持广播通信,UE自主资源选择的方式如用于单播或者组播通信方式,无法有效避免半双工影响,会造成无法成功接收组内其他成员发送的消息、可靠性下降。

资源接收模块,用于在确定UE自身需要其他UE提供的发送资源时,使 用资源分配UE分配的发送资源,和/或,在资源辅助分配UE提供的可进行资源选择的发送资源集合中选择发送资源,其中,资源分配UE是向其它UE分配发送资源的UE,资源辅助分配UE是向其它UE提供可进行资源选择的资源集合的UE。
本申请有益效果如下:
在本申请实施例提供的技术方案中,由于是由部分UE(例如1个UE)向其他UE进行资源分配或者辅助调度,因此解决了3GPP Release14和Release15的LTE-V2X直通链路通信仅支持广播通信,UE自主资源选择的方式如用于单播或者组播通信方式,无法有效避免半双工影响,会造成无法成功接收组内其他成员发送的消息、可靠性下降的问题。能够实现降低干扰、有效避免半双工影响、提高V2X直通链路通信可靠性。
此处所说明的附图用来提供对本申请的进一步理解,构成本申请的一部分,本申请的示意性实施例及其说明用于解释本申请,并不构成对本申请的不当限定。在附图中:
图1为背景技术中LTE-V2X单载波上发送资源的选择时间轴示意图;
图2为本申请实施例中资源分配方法实施流程示意图;
图3为本申请实施例中接收资源分配的方法实施流程示意图;
图4为本申请实施例中用户设备一结构示意图;
图5为本申请实施例中用户设备二结构示意图。
申请人在申请过程中注意到:
3GPP Release 14和Release 15定义了LTE-V2X的协议,包括两种通信方式,分别为终端之间直通链路通信方式,以及终端与基站之间的上/下行链路通信方式。其中,终端之间直通链路通信方式包括2种发送模式,分别是直 通链路发送模式3和直通链路发送模式4。直通链路发送模式3为基站为终端调度分配资源,直通链路发送模式4为UE自主选择资源。
3GPP Release 14的LTE-V2X协议为V2X第一阶段的技术规范,能够满足基本的需求集,支持3GPP TR 22.885的基本道路安全类业务。3GPP Release15的LTE-V2X协议为V2X第二阶段的技术规范,引入了载波聚合、高阶调制、时延缩减等机制,相关增强的功能可支持3GPP TR 22.886中的部分eV2X应用用例。3GPP Release 14和Release 15定义的LTE V2X在直通链路通信方式中,只支持广播通信。同时,3GPP TR 22.886中3GPP Release 14和Release15LTE-V2X无法支持的用例,则在3GPP V2X第三阶段进行研究和支持。
3GPP RAN#80会议通过了3GPP V2X第三阶段的NR V2X SI(Study Item)的立项,研究方向中包括直通链路支持单播、组播和广播的通信方式。
对于单播和组播通信,以及部分可靠性要求极高的广播业务(如可靠性指标为99.999%),采用3GPP Release14和Release 15LTE-V2X方式无法全面满足需求,如覆盖外场景、进行单播或者组播通信的UE,通过自主选择资源无法有效避免半双工影响,造成无法成功接收组内其他成员发送的消息等。
基于此,本申请实施例中提出一种资源分配方案,由部分UE(例如1个UE)向其他UE进行资源分配或者辅助调度,实现降低干扰、有效避免半双工影响、提高V2X直通链路通信可靠性的目的。下面结合附图对本申请的具体实施方式进行说明。
在说明过程中,将分别从提供资源的UE与接收资源的UE的实施进行说明,然后还将给出二者配合实施的实例以更好地理解本申请实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施,实际上,当提供资源的UE与接收资源的UE分开实施时,其也各自解决UE侧的问题,而二者结合使用时,会获得更好的技术效果。
在说明中将会对相关变量进行标记,例如:将计算待分配资源的UE数量记为N,计算可用候选资源中时域资源计数的数量记为M;单个数据包的发送次数记为k,为每个UE分配的时域资源个数记为x等等,但本领域技术人 员容易了解,相关变量可由其他字符替代,且替代后并不影响方案的实施和理解。
说明中,为更清晰的表达,将对各实施例进行标号,例如实施例1、实施例2等,但这不意味每个实施例都是独立的,事实上本领域技术人员可以根据实际需要对各实施例进行结合,例如,将实施例1中的确定资源分配UE的方式与实施例2中资源分配UE为其他UE进行发送资源分配的方式相结合。
在接受资源分配/辅助分配的UE一侧,对于接受资源分配的UE,在接受到分配的资源后执行数据发送;接受资源辅助分配的UE,在接收到分配的资源集合后,按照现有机制执行资源选择然后执行发送即可。因此下面实施中将主要对资源分配UE或者资源辅助分配UE侧的实施进行说明,但是为了更好地说明二者的配合实施,说明中也会对涉及到的另一侧进行说明。
下面首先对资源分配UE或者资源辅助分配UE侧的实施例进行说明。
