  • Mechanism 1 (only negative acknowledgement (Negative Acknowledgement, NACK), or connection-less mechanism (connection-less)): If the data is received but cannot be decoded, NACK is fed back, and no feedback is given in other cases. In this case, if the receiver does not receive a NACK, it is considered that all receivers have successfully received and decoded the data, but one disadvantage of this mechanism is that the sender may confuse the data received successfully and the receiver did not successfully receive it. There are two cases of SCI, that is, although the receiver did not successfully receive the SCI and data, the sender thought that the receiver received it successfully. This method is suitable for connectionless multicast scenarios.
  • Mechanism 2 (Acknowledgement (ACK)/NACK, or connection-based): If the data is received but cannot be resolved or SCI is received but no data is received, NACK is fed back, if received The data is correctly solved and ACK is fed back. At this time, if the sender receives a NACK from a certain sender user, or does not receive an ACK or NACK, the sender considers that the transmission to the terminal failed, and receives an ACK from a sender, then sends The party considers the transmission to this terminal to be successful.

首先，对本申请实施例中的相关术语进行解释说明；
一、LTE和NR Uu口的非连续接收
LTE和NR都引入了DRX机制，通过配置DRX开(on)和DRX关(off)时间来达到用户设备(User Equipment，UE)的省电。如图2所示，在持续时间(on duration)期间是DRX on的区间，如果UE没有调度在on duration期间，则会进入一个DR周期(cycle)的off期间。
其中，配置DRX的时候会配置激活定时器(onDurationTimer)，去激活定时器(drx-InactivityTimer)，重传定时器(drx-RetransmissionTimer)，长DRX周期起始偏移量(longDRX-CycleStartOffset)等参数。
UE在配置了DRX后，如果发送或接收数据解码失败，UE需要进入激 活时间监听控制信道，等待网络调度的重传。其中，在on duration期间，若UE在某个时隙(slot)被调度并接收数据后，很可能在接下来的几个slot内继续被调度。因此，每当UE被调度初传数据后就启动或重启定时器drx-InactivityTimer，UE将一直位于激活态直到该定时器超时。
对于下行数据接收，UE会在接收到物理下行控制信道(Physical Downlink Control Channel，PDCCH)指示的下行数据传输并反馈混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)信息后，给对应的HARQ进程启动下行回传定时器(HARQ RTT Timer)，其中，RTT为往返时延(Round Trip Time)。如果在HARQ RTT Timer超时后，且该HARQ进程的数据没有成功解码，则UE启动重传定时器(drx-RetransmissionTimer)，并监听PDCCH，等待传输。
对于上行数据发送，UE会在接收到PDCCH指示上行数据传输后，给对应的HARQ进程启动上行回传定时器HARQ RTT Timer。在HARQ RTT Timer超时后，则UE启动重传定时器(drx-ULRetransmissionTimer)，并进入激活状态监听PDCCH，等待网络调度的传输。
二、LTE旁链路SL的检测(LTE sidelink sensing)
LTE sidelink sensing的基本工作原理如下：
在检测窗(sensing window)内进行测量，在每个检测传输时间间隔(Transmission Time Interval，TTI)内解调度分配(Scheduling Assignment，SA)及进行干扰测量。
其中，基于图3，UE根据以下步骤进行资源选择：
步骤1，排除UE发送数据的资源；
步骤2，终端解调收到的SA，得到其他UE资源预留资源，其中，排除其他UE预留的资源；
步骤3，在sensing window内进行能量检测，测量参考信号强度指示(Reference Signal Strength Indication，RSSI)，根据测量结果，排除干扰大的资源；
步骤4，在选择窗内，从干扰最小的20％的资源中随机选择一个子帧(subframe)进行周期的资源预留。
三、LTE旁链路SL的部分检测(Partial sensing in LTE SL)
LTE车用无线通信技术(Vehicle to X，V2X)中部分检测主要是为了省电而设计的，是为了支持行人对车辆(Pedestrian to Vehicle，P2V)的通信，PUE支持两种模式的资源选择方式。一种为随机的资源选择；另一种模式为先进行部分检测，基于部分检测的结果选择资源，进行半静态的资源预留。其中，PUE选择哪种模式为无线资源控制(Radio Resource Control，RRC)配置的，当RRC配置为支持两种模式的资源选择时，PUE实现决定采用哪种资源选择方式。
其中，基于图4，终端进行部分检测并进行资源检测的方式如下：
PUE检测窗口为在[n-1000,n]的范围内的窗口1，长度Y以及k为RRC配置的参数，k的取值范围可以为{1,2,3,…,10}。[n+T1,n+T2]内的窗口2为高层配置的PUE的选择窗口。PUE在检测窗口1中检测其他终端发送的旁链路控制信息(Sidelink Control Information，SCI)，根据检测的SCI以及预留周期，推测其他终端在窗口2内的资源预留情况，该PUE可以根据这些信息排除选择窗口中不满足条件的资源。在剩余的资源中选择至少20％(窗长Y的20％)的资源作为候选资源集合，上报给媒体接入控制(Medium Access Control，MAC)层，MAC层从候选资源集合中随机选择一个资源作为该PUE的候选资源。该PUE对选择的资源进行周期预留，预留周期在SCI中指示。
四、旁链路的随机选择(Random selection in SL)
如果用户进行随机选择，则在图4中选择窗口内随机选择资源，不需要进行检测。
五、新空口中旁链路的检测(Sensing in NR SL)
在Mode 2资源分配模式中，支持基于检测(sensing)进行资源选择。其原理和LTE SL mode4下的sensing机制类似。具体的工作方式如下：1)发送端(TX)UE在资源选择被触发后，确定资源选择窗口；2)UE在资源选择的之前，需要确定资源选择的备选资源集(candidate resource set)，根据资源选择窗口内的资源上测量的参考信号接收功率(Reference Signal Receiving Power，RSRP)与相应的RSRP阈值(threshold)做对比，如果RSRP低于RSRP阈值，那么该资源可以纳入备选资源集合；3)资源集合确定后，UE 随机在备选资源集合中选择传输资源。另外，UE在本次传输可以为接下来的传输预留传输资源。
在Rel-16 NR SL中，TX UE会对其分配的资源进行资源预留(预留分为周期性预留和非周期性预留)，预留资源为以后的物理侧旁链路控制信道(Physical Sidelink Control Channel，PSCCH)或物理侧旁链路共享信道(Physical Sidelink Shared Channel，PSSCH)传输所用。非周期预留可以通过SCI中的时间资源分配(Time resource assignment)域实现，预留的资源至少可以用作同一个传输块(Transport Block，TB)的传输。周期预留可以通过SCI中的资源保留周期(Resource reservation period)域实现，当前周期预留的周期性资源可以用作下一个TB的传输。
六、SL资源抢占(Resource pre-emption)in NR SL
在Mode 2资源分配模式中，支持资源pre-emption机制，该机制的简要描述如下：一个UE已经预留/选择的资源和其它具有更高优先级业务的UE所预留/选择的资源重叠(部分重叠)，如果该UE在相关资源上的SL-RSRP测量值大于某个相关(associated)SL-RSRP门限值时，该UE会触发资源的重新选择。所述的业务优先级和所述的SL-RSRP门限由在所述资源上的TB传输确定。
如图5所示，UE为了判断已经预留或选择的资源(PSCCH/PSSCH资源)是否被抢占，UE至少在‘m-T3’时刻进行资源选择的重评估，‘m’时刻是资源所在的时刻或者资源预留信息发送的时刻，T3至少包括UE进行资源选择处理的时长。
七、强制类型转换(Cast type)
NR sidelink支持广播，组播和单播三种传输方式。NR sidelink的组播支持基于连接的组播与无连接的组播两种用例，基于连接的组播是指组播的UE间建立了连接，无连接模式是指组播UE不知道组内其他UE，没有建立连接的场景。对于组播的情况，多个收端在进行HARQ反馈的时候支持两种机制：
机制1(仅反馈否定确认(Negative Acknowledgement，NACK)，或者无连接机制(connection-less))：如果收到该数据但是无法解出来，反馈NACK，其他情况下不反馈。这种情况下收方如果没有收到NACK，则认为所有收端 都成功收到并解出了该数据，但是这个机制的一个缺点是发方可能会混淆成功接收数据和收方没有成功收到SCI的两种情况，即虽然收方没有成功收到SCI与数据，但发方以为收方接收成功了。该方式适用于无连接的组播场景。
机制2(反馈肯定确认(Acknowledgement，ACK)/NACK，或者基于连接机制(connection-based))：如果收到该数据但是无法解出来或者收到SCI但是没有收到数据，反馈NACK，如果收到该数据并且正确解出来，反馈ACK。此时如果发方收到某个发送端用户发来的NACK，或没有收到ACK或NACK，则发方认为发送给这个终端的传输失败，收到某个发送端发来的ACK，则发方认为发送给这个终端的传输成功。该方式适用于基于连接的组播场景。
此外，还需要说明的是：
1)DRX激活时间(active time)为UE监听/接收/解调/测量特定信道/信号/信令的时间(激活期)，所述特定信道/信号/信令可以为以下至少一项：物理侧旁链路控制信道(Physical Sidelink Control Channel，PSCCH)、物理侧旁链路共享信道(Physical Sidelink Shared Channel，PSSCH)、物理旁链路广播信道(Physical Sidelink Broadcast Channel，PSBCH)、物理旁链路反馈信道(Physical Sidelink Feedback Channel，PSFCH)、旁链路控制信息(Sidelink Control Information，SCI)、旁链路同步信号块(Sidelink Synchronization Signal and PBCH block，S-SSB)、参考信号(Reference Signal，RS)，例如包含DRX on duration，非激活定时器(inactivity timer)运行时间，重传定时器(retransmission timer)运行时间中的至少一项。
2)DRX非激活时间(inactive time)为UE不监听/接收/解调/测量特定信道/信号/信令的时间(即休眠期)，其中，该特定信道/信号/信令可以为以下至少一项：PSCCH、PSSCH、PSBCH、PSFCH、SCI、S-SSB、RS；例如，包含DRX off duration，RTT定时器运行时间中的至少一项。
3)检测(sensing)时间在本领域中还可以替换以下其他表述：sensing窗、sensing时刻、sensing范围、sensing时隙集合、sensing资源集、sensing样本。
4)T1/T2：T1和T2的定义分别为资源选择(重选)触发时刻n距离包含资源选择时间的时间区间[n+T 1,n+T 2](即可以在该时间区间内确定出资 源选择时间)上下边界的距离，其值均取决于UE实现，且需满足

下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的资源的选择方法进行详细地说明。
如图6所示，本申请实施提供了一种资源的选择方法，该方法的步骤包括：
步骤602，第一终端通过资源分配方式中的至少一种方式进行资源选择，其中，资源分配方式包括以下至少一项：检测、随机选择。
其中，检测方式又可称为资源感知方式。通过上述步骤602，第一终端可以通过检测的资源分配方式和/或随机选择的资源分配方式进行资源选择，实现了在不同资源分配方式中切换或并行执行，从而解决了相关技术的资源选择过程中终端不能根据实际需求灵活切换资源分配方式，导致业务传输的可靠性较低以及功耗较高的问题。
需要说明的是，本申请实施例中的资源分配方式与资源池相关。此外，本申请实施例中的检测可以是部分检测(partial sensing)和全部检测(full sensing)。
可选地，本申请实施例中的第一终端通过资源分配方式中的至少一种方式进行资源选择包括：
1)在传输第一传输块的情况下，第一终端基于检测的方式选择用于第一传输块传输的资源；
2)在传输第二传输块的情况下，第一终端基于随机选择的方式选择用于第二传输块传输的资源；
3)在执行第一进程的情况下，第一终端基于检测的方式选择用于第一进程的资源；
4)在执行第二进程的情况下，第一终端基于随机选择的方式选择第二进程的资源；
其中，第一传输块不同于第二传输块；第一进程不同于第二进程。
由上述资源选择方式可见，针对不同的传输块，和/或不同的进程可以选择不同的资源分配方式，明确了不同情况下资源分配的方式，保证了终端间通信业务的可靠性。
在本申请实施例的可选实施方式中，对于第一终端通过资源分配方式中的至少一种方式进行资源选择，还可以包括：
1)在第一传输或第一包对应的检测时间与已经使能的检测时间具有重叠部分的情况下，第一终端基于已经使能的检测时间的至少部分检测结果进行资源的选择；或，
2)在第一传输或第一包对应的检测时间与已经使能的检测时间的距离小于预设阈值的情况下，第一终端已经使能的检测时间中的至少部分检测结果进行资源的选择。
可见，对于上述两种情况，可以通过已经使能的检测时间中的至少部分检测结果进行资源的选择，即明确了可以通过检测的资源分配方式进行资源选择，从而保证了终端间通信业务的可靠性。
在本申请实施例的可选实施方式中，对于第一终端通过资源分配方式中的至少一种方式进行资源选择包括：
在第一终端在第一时间开始检测的情况下，第一终端基于检测的方式对第一时间窗内，和/或，对第二时间窗内的传输或包进行资源选择；
其中，第一时间窗的起点为第一时间，第一时间窗的长度为N；第二时间窗的起点为第三时间，第二时间窗的长度为M；第三时间为以下之一：资源选择的触发时间、资源重选的触发时间、资源重评估的触发时间；N和M为大于零的正整数。
需要说明的是，上述第一时间窗和第二时间窗内的传输或包触发延长检测时间。此外，本申请实施例中的传输或包所对应的逻辑信道也是不同的，以及，传输或包所对应的混合自动重传请求确认HARQ-ACK信息不同。
在本申请实施例的可选实施方式中，该第一时间窗，和/或，第二时间窗内的传输或包触发延长检测时间，检测时间延长的长度通过以下至少之一的方式获取：网络配置、预配置、第二终端的指示、协议约定、第一终端确定。
在本申请实施例的可选实施方式中，第一终端通过资源分配方式中的至 少一种方式进行资源选择包括以下至少一项：

2)第一终端基于随机选择的方式选择用于重传的资源；
3)第一终端基于检测的方式选择用于初传的资源；
4)第一终端基于检测的方式选择用于重传的资源。
可见，在本申请实施例中被选择的资源可以是用于初传的资源和用于重传的资源，即可以基于不同的资源分配方式对不同的资源进行选择。当然上述资源选择的方式也可以组合，例如第一终端基于随机选择的方式选择用于初传的资源，以及第一终端基于检测的方式选择用于重传的资源。
在本申请实施例的可选实施方式中，对于第一终端通过资源分配方式中的至少一种方式进行资源选择包括：
1)在传输非周期业务的情况下，第一终端基于随机选择的方式进行资源的选择；或者，
2)在传输周期性业务的情况下，第一终端基于检测的方式进行资源的选择。
可见，可以根据业务的周期性选择不同的资源分配方式进行资源的选择，以保证终端间通信业务的可靠性。
需要说明的是，本申请实施例中的资源分配方式与非连续接收DRX的配置具有关联关系；可选地，本申请实施例中的DRX配置为第一终端的DRX配置、DRX配置为与第一终端进行通信的第二终端的DRX配置。

需要说明的是，该第一终端在非检测时间进行接收信道或信令，在终端间传输突发业务(例如信息量大于阈值的业务)时，也要接收。另外，在非 检测时间进行接收也表明已配置的DRX被禁用。
下面结合本申请实施例的具体实施方式对本申请中的资源的选择方法进行举例说明；如图7所示，终端基于部分检测(partial sensing)进行资源选择，来包1对应的partial sensing窗为图7中窗口1，来包1对应的资源选择窗为图7中窗口2。假设来包2对应的partial sensing窗(该窗可以是虚拟的/推测的，可能不存在)为图7中窗口3，此时来包2对应的partial sensing窗和来包1对应的partial sensing窗部分重叠，则终端可以基于重叠部分的sensing结果选择用于来包2传输的资源。

步骤802，第一终端确定第一资源；其中，第一资源包括以下至少一项：第一终端所期望的资源、第一终端不期望的资源；
步骤804，第一终端向第二终端推荐第一资源。
通过上述步骤802和步骤804，第一终端可以向第二终端推荐所期望和/或不期望的资源，从而使第二终端能够明确哪些资源可以用于传输，哪些资源不能用于传输，确保了在终端间通信时业务的可靠性同时节省了终端功耗，从而解决了相关技术中终端可能在某些特定时间进行传输，但对应传输可能失败或不能被处理，使得业务可靠性较低以及功耗较高的问题。
需要说明的是，本申请实施例中期望的资源可以是希望用于传输的资源，或希望在对应的资源上进行传输，不期望的资源可以是不希望用于传输的资源，或不希望在对应的资源上进行传输。
此外，本申请实施例中的第一终端可以向第二终端推荐所期望和/或不期望的资源可以解释理解为第一终端调度第二终端进行传输，或，第一终端调度所期望和/或不期望的资源给第二终端用于传输，或，第一终端可以向第二终端指示所期望和/或不期望的资源，另外，本申请实施例中的第一资源可以为半静态资源。

可选地，本申请实施例的方法还可以包括：第一终端向第二终端指示以下至少一项：第一终端是否配置DRX、第一终端是否使能DRX。
在本申请实施例步骤804中涉及到的第一终端向第二终端推荐第一资源的方式，可以是：第一终端通过第一节点向第二终端推荐第一资源。
