  • UE2 selects resources according to the interception, and uses the resources to send sideline data to UE1. Since UE2 and UE3 are far apart, they cannot hear each other's transmissions. Therefore, UE2 and UE3 may select the same transmission resource, and the data sent by UE3 will interfere with the data sent by UE2, which is the hidden node problem.
  • Half-duplex problem when the terminal selects transmission resources by listening, within the listening window, if the terminal sends sideline data on a certain time slot, due to the limitation of half-duplex, the The terminal cannot receive data sent by other terminals in this time slot, and there is no listening result. Therefore, when the terminal performs resource exclusion, it will exclude all resources corresponding to this time slot in the selection window to avoid contact with other terminals. interference. Due to the limitation of half-duplex, the terminal excludes many resources that do not need to be excluded. In addition, since the terminal transmits data in this time slot, if another terminal also selects the same resource in this time slot to send data, the two terminals cannot determine that there is a resource conflict due to the limitation of half-duplex.

图1是本申请实施例适用的一种通信系统100的示意图。车载终端(车载终端131和车载终端132)在侧行链路的资源上自主选取传输资源进行数据传输。可选地,车载终端可以随机选取传输资源,或者通过侦听的方式选取传输资源。
需要说明的是,在侧行通信中,根据进行通信的终端所处的网络覆盖情况,可以分为网络覆盖内侧行通信,如图2所示;部分网络覆盖侧行通信,如图3所示;及网络覆盖外侧行通信,如图4所示。
图2:在网络覆盖内侧行通信中,所有进行侧行通信的终端均处于同一基站的覆盖范围内,从而,上述终端均可以通过接收基站的配置信令,基于相同的侧行配置进行侧行通信。
图3:在部分网络覆盖侧行通信情况下,部分进行侧行通信的终端位于基站的覆盖范围内,这部分终端能够接收到基站的配置信令,而且根据基站的配置进行侧行通信。而位于网络覆盖范围外的终端,无法接收基站的配置信令,在这种情况下,网络覆盖范围外的终端将根据预配置(pre-configuration)信息及位于网络覆盖范围内的终端发送的物理侧行广播信道(Physical Sidelink Broadcast Channel, PSBCH)中携带的信息确定侧行配置,进行侧行通信。
图4:对于网络覆盖外侧行通信,所有进行侧行通信的终端均位于网络覆盖范围外,所有终端均根据预配置(pre-configuration)信息确定侧行配置进行侧行通信。
需要说明的是,设备到设备通信是基于终端到终端(Device to Device,D2D)的一种侧行链路(Sidelink,SL)传输技术,与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同,因此具有更高的频谱效率以及更低的传输时延。车联网系统采用终端到终端直接通信的方式,在3GPP定义了两种传输模式,分别记为:第一模式和第二模式。本申请实施例可以应用于第二模式。
第一模式:终端的传输资源是由基站分配的,终端根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。如图2所示,终端位于网络覆盖范围内,网络为终端分配侧行传输使用的传输资源。
第二模式:终端在资源池中选取一个资源进行数据的传输。如图4所示,终端位于小区覆盖范围外,终端在预配置的资源池中自主选取传输资源进行侧行传输;或者,如图2所示,终端在网络配置的资源池中自主选取传输资源进行侧行传输。
需要说明的是,在NR-V2X中,用户可能处在一个混合的模式下,即既可以使用第一模式进行资源的获取,又同时可以使用第二模式进行资源的获取。
在NR-V2X中,支持自动驾驶,因此对车辆之间数据交互提出了更高的要求,如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在长期演进车辆到其他设备(Long Term Evolution Vehicle to Everything,LTE-V2X)中,支持广播传输方式,在NR-V2X中,引入了单播和组播的传输方式。对于单播传输,其接收端终端只有一个终端,如图5所示,UE1、UE2之间进行单播传输;对于组播传输,其接收端是一个通信组内的所有终端,或者是在一定传输距离内的所有终端,如图6所示,UE1、UE2、UE3和UE4构成一个通信组,其中UE1发送数据,该组内的其他终端设备都是接收端终端;对于广播传输方式,其接收端是发送端终端周围的任意一个终端,如图7所示,UE1是发送端终端,其周围的其他终端,UE2-UE6都是接收端终端。
在侧行传输系统中引入了资源池,所谓资源池即传输资源的集合,无论是网络配置的传输资源还是终端自主选取的传输资源,都是资源池中的资源。可以通过预配置或网络配置的方式配置资源池,可以配置一个或多个资源池。资源池又分为发送资源池和接收资源池。发送资源池即该资源池中的传输资源用于发送侧行数据;接收资源池即终端在该资源池中的传输资源上接收侧行数据。
在NR-V2X中引入2阶侧行控制信息(Sidelink Control Information,SCI),第一阶SCI承载在物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)中,用于指示物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH)的传输资源、预留资源信息、调制编码方案(Modulation and Coding Scheme,MCS)等级、优先级等信息,第二阶SCI在PSSCH的资源中发送,利用PSSCH的解调参考信号(Demodulation Reference Signal,DMRS)进行解调,用于指示发送端标识(Identity,ID)(也可以称之为源(Source)标识)、接收端ID(也可以称之为目标(Destination)ID)、混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)ID、新数据指示(New Data Indicator,NDI)等用于数据解调的信息。第一个符号通常用作自动增益控制(Auto Gain Control,AGC),PSCCH从时隙的第2个符号开始,最后一个符号通过用作保护间隔(Guard Period,GP)。第二阶SCI从PSSCH的第一个DMRS符号开始映射,先频域再时域映射,如图8所示,PSCCH占据3个符号(符号1、符号2、符号3),PSSCH的DMRS占据符号4、符号11,第二阶SCI从符号4开始映射,在符号4上和DMRS频分复用,第二阶SCI映射到符号4、符号5、符号6,第二阶SCI占据的资源大小取决于第二阶SCI的比特数。
在上述第二模式的传输方式中,终端设备在资源池中随机选取传输资源,或者根据侦听结果选取传输资源,这种资源选取方式可以在一定程度上避免终端之间的干扰,但是还存在如下所述的问题:
1.隐藏节点(Hidden node):如下图9所示,UE2根据侦听选取资源,并利用该资源向UE1发送侧行数据,由于UE2和UE3相距较远,互相侦听不到对方的传输,因此,UE2和UE3可能选取相同的传输资源,则UE3发送的数据会对UE2发送的数据造成干扰,这就是隐藏节点问题。
2.半双工(Half-duplex)问题:当终端通过侦听选取传输资源时,在侦听窗口内,如果该终端在某个时隙上发送侧行数据,由于半双工的限制,该终端在该时隙上不能接收其他终端发送的数据,也没有侦听结果,因此,终端在进行资源排除时,会把选择窗内与该时隙对应的资源全部排除掉,以避免和其他终端的干扰。由于半双工的限制会导致该终端排除了很多不需要排除的资源。另外,由于终端在该时隙上发送数据,如果有另外一个终端也选择了该时隙上相同的资源发送数据,这两个终端由于半双工的限制,都无法确定存在资源冲突,就会导致这两个终端持续的资源冲突。
由于上述第二传输模式中资源选取过程中存在的问题,提出了增强的资源选取方案。在上述方式的基础上,还可以通过一个终端(UE1)为另一个终端(UE2)发送资源集合,用于UE2进行资源选取。该资源集合例如可以是下面的信息:
资源集合:该资源集合是可用资源集合,UE1根据侦听结果获取可用资源集合,并且将该资源集合发送给UE2,当UE2在为向UE1发送的侧行数据选取资源时,UE2可以从该可用资源集合中选取资源,从而可以提升UE1接收该侧行数据的可靠性;或者,该资源集合也可以是不可用资源集合,UE1向UE2上报该资源集合,UE2在选取资源的时候尽量避免选取该资源集合中的资源。
具体的传输资源:UE1向UE2发送的信息中包括具体的传输资源,UE2利用该传输资源向UE1发送侧行数据,此时,相当于UE1为UE2分配了侧行传输资源。
也就是说,在上述资源分配方式中,终端设备在进行资源选取过程中,需要结合其他终端发送的资源集合,从而可以提高传输可靠性。
然而,在上述增强的资源选取方案中,UE1为UE2发送资源集合,以辅助UE2的资源选取,但是UE1如何确定资源集合,以避免上面所述的半双工问题、隐藏节点等问题是需要解决的问题。
基于上述问题,本申请提出了一种确定资源集合的方案,可以确定资源集合,并能够在资源选取中避免出现隐藏节点、半双工等问题,提升了资源选取的可靠性。
以下通过具体实施例详述本申请的技术方案。

S220,该第一终端设备向第二终端设备发送该目标资源集合,或者,该第一终端设备根据该目标资源集合向第二终端设备发送第一指示信息;其中,该目标资源集合用于该第二终端设备确定候选传输资源,该第一指示信息用于指示该第二终端设备进行资源重选;
S230,该第二终端设备接收该第一终端设备发送的该目标资源集合,或者,该第二终端设备接收该第一终端设备根据该目标资源集合发送的该第一指示信息。
可选地,该目标资源集合具体用于该第二终端设备确定需要排除的资源。进一步地,该目标资源集合具体用于该第二终端设备进行资源选取时确定需要排除的资源。也即,该目标资源集合中的传输资源是不建议该第二终端设备使用的传输资源,当该第二终端设备进行数据传输时,应该避免使用该目标资源集合中的传输资源。
也就是说,在本申请实施例中,终端设备可以将有可能存在资源冲突,或半双工问题,或导致PSFCH发送、接收冲突问题的传输资源发送给其他终端设备,使得其他终端设备避免选取这些传输资源,从而可以避免半双工问题、隐藏节点等问题。
可选地,该第二终端设备获取该第一终端设备发送的第一指示信息,根据该第一指示信息确定进行资源重选。例如,该第一指示信息用于指示存在资源冲突,或半双工问题,或导致PSFCH发送、接收冲突问题,当该第二终端接收到该第一指示信息时,确定进行资源重选,以避免资源冲突,或半双工问题,或导致PSFCH发送、接收冲突问题。
可选地,该第一终端设备可以是该第二终端设备发送侧行数据的接收端设备。例如,当UE1是UE2发送侧行数据的接收端设备时,UE1可以根据侦听获取资源集合,确定在该资源集合中的元素是否存在资源冲突,以及是否会导致UE1存在半双工的问题。
可选地,该第一终端设备也可以是该第二终端设备所在通信组内的终端设备。例如,UE1、UE2和UE3构成一个通信组,终端进行组播通信时,组内的所有的终端都需要进行接收,如果UE1检测到UE2和UE3会在同一个时隙内发送侧行数据,则UE1可以向UE2和/或UE3发送资源集合,该资源集合中包括该时隙信息,使得UE2和/或UE3避免使用该时隙进行数据传输,从而可以避免UE2和UE3之间的半双工问题。
可选地,在一些实施例中,S210具体可以是:
该第一终端设备根据第一信息确定该目标资源集合;
其中,该第一信息包括以下中的至少一种:
该第一终端设备检测的侧行参考信号接收功率(Reference Signal Received Power,RSRP)和/或侧行接收信号强度指示(Received Signal Strength Indication,RSSI);
该第一终端设备预测的侧行RSRP和/或侧行RSSI;
该第一终端设备检测的与该第二终端设备预留的传输资源存在冲突的传输资源;
待发送数据所占用的时域资源;
待接收的PSFCH所占用的时域资源;
待接收的PSFCH所占用的时域资源对应的PSSCH所占用的时域资源;
待发送的PSFCH所占用的时域资源;
待发送的PSFCH所占用的时域资源对应的PSSCH所占用的时域资源。
可选地,在一些实施例中,该目标资源集合中的传输资源所具有的特性详见如下示例1至示例5中的至少一个示例。
示例1,该目标资源集合中的传输资源的侧行RSRP或者侧行RSSI超过第一门限值。
对于侧行RSRP,该第一门限值为RSRP值。而对于侧行RSSI,该第一门限值为RSSI值。
假设UE1进行资源侦听,在侦听窗内检测其他用户的SCI,并且进行侧行RSRP测量,如果其他用户(如UE3)预留了传输资源S(用于重传或用于传输下一个数据块的资源),并且检测的侧行RSRP高于第一门限值,则UE1将该资源S作为目标资源集合中的元素发送给UE2,即UE1认为该资源S已经被其他终端预留,如果UE2使用了该资源S,就会导致和其他终端的传输冲突,降低传输可靠性,UE1将该资源S发送给UE2,UE2在选取传输资源的时候避免选取该资源S,从而可以避免隐藏节点的问题,即避免了由于UE2和UE3距离远,UE2检测不到UE3预留的传输资源,而选取了该资源S导致传输冲突,通过UE1将UE3预留的传输资源发送给UE2,可以避免这样的问题。
例如,如图11所示,UE1进行资源侦听,在侦听窗内检测到某个终端,如UE3,在资源A上发送的SCI,并且侧行RSRP超过第一门限值,并且UE3预留了下一个周期(如100ms)后的传输资源B,则UE1将传输资源B作为目标资源集合中的一个资源;在侦听窗内检测到某个终端,如UE4,在资源C上发送的SCI,但是侧行RSRP没有超过第一门限值,UE4预留了下一个周期(如200ms)后的传输资源D,则UE1不将传输资源D作为目标资源集合中的一个资源。UE1将目标资源集合(包括传输资源B)发送给UE2。
可选地,在示例1中,该目标资源集合中的传输资源的侧行RSRP为预测的侧行RSRP,或者,该目标资源集合中的传输资源的侧行RSSI为预测的侧行RSSI。
例如,上图11中的资源A,UE1在资源A上检测到UE3的SCI,并且预留了资源B,UE1会认为UE3会在资源B上发送侧行数据,并且预测在资源B上的侧行RSRP与资源A上的侧行RSRP相同,因此UE1将资源B发送给UE2,UE2即可获知资源B上会有数据传输,并且侧行RSRP超过第一门限值。
需要说明的是,侧行RSSI的描述与上述侧行RSRP的描述类似,在此不再赘述。
可选地,在示例1中,该第一门限值为预配置或协议约定的,或者,该第一门限值为网络设备配置的,或者,该第一门限值为第三终端设备配置的。
例如,预配置信息包括该第一门限值;或者,第一终端设备接收网络设备发送的配置信息,该配置信息中包括该第一门限值;或者,第一终端设备接收第三终端设备发送的侧行数据,该侧行数据(包括SCI,媒体接入控制控制元素(Media Access Control Control Element,MAC CE),基于PC5接口的无线资源控制(Radio Resource Control,RRC)信令(PC5-RRC信令)等)中包括该第一门限值。
可选地,在示例1中,该第一门限值为根据该第二终端设备发送的侧行信息确定的。
例如,在第一终端设备和第二终端设备建立连接时,第二终端设备通过PC5-RRC信令发送侧行信息给第一终端设备,该侧行信息包括该第一门限值。又例如,第二终端设备通过SCI、MAC CE等发送侧行信息给第一终端设备,该侧行信息包括该第一门限值。又例如,第二终端设备在给第一终端设备发送触发第一终端设备发送目标资源集合的信令中包括该第一门限值。
可选地,在示例1中,该第一门限值为该第一终端设备确定的。例如在第一终端设备和第二终端设备建立连接时,第一终端设备通过PC5-RRC信令发送给第二终端设备;又例如,第一终端设备向第二终端设备发送目标资源集合时,同时发送该第一门限值。
可选地,在示例1中,该第一门限值为与第一优先级信息相关的数值,或者,该第一门限值为根据第一优先级信息确定的。
可选地,该第一优先级信息包括以下中的至少一种:
SCI中携带的优先级、侧行数据对应的业务的优先级、侧行数据对应的逻辑信道的优先级。
可选地,在示例1中,该第一优先级信息为从该第二终端设备处获取的,或者,该第一优先级信息为从资源池配置信息中获取的。
例如,在通过预配置、网络设备配置、第三终端设备配置或第二终端设备配置该第一门限值时,该第一门限值是根据第一优先级信息确定的参数。例如,为不同的优先级配置相对应的第一门限值。
例如,在资源池配置信息中包括该第一门限值,资源池配置信息可以是预配置的或网络配置的,该第一门限值是根据优先级确定的,即为不同的优先级分别配置第一门限值。第一终端设备在确定目标资源集合时,会根据优先级确定目标资源集合,该优先级可以是预配置的优先级,或者是,第二终 端设备发送给第一终端设备的优先级,例如第二终端设备在触发第一终端设备发送目标资源集合时,将优先级信息发送给第一终端设备,第一终端设备根据该优先级进行资源侦听,并且确定该优先级对应的第一门限值,第一终端设备将根据该优先级确定的目标资源集合发送给第二终端设备。
又例如,在资源池配置信息中包括一个优先级,该优先级可以认为是一个缺省的优先级,第一终端设备在进行资源侦听时,如果没有通过其他方式确定优先级(例如第二终端设备发送给第一终端设备优先级),则使用该缺省的优先级进行侦听,并且确定该缺省优先级对应的第一门限值,第一终端设备将根据该缺省优先级确定的资源集合发送给第二终端设备。
可选地,该第一终端设备将该第一门限值发送给该第二终端设备。
例如,当第一门限值是由第一终端设备确定时,第一终端设备将目标资源集合和第一门限值都发送给第二终端设备,第二终端设备根据该第一门限值可以确定该目标资源集合中的传输资源上的RSRP值都是大于该第一门限值的,从而可以确定目标资源集合中的传输资源的干扰水平。
可选地,该第一终端设备将该第一门限值所对应的第一优先级信息发送给该第二终端设备。
示例2,该目标资源集合中的传输资源为存在冲突的传输资源。
例如,当UE2发送侧行数据时,会通过SCI指示预留传输资源,该传输资源可以是用于本数据块重传的传输资源或用于下一个数据块的传输资源,如果UE1检测到UE2预留的传输资源与其他终端(如UE3)预留的传输资源有冲突,则UE1将该传输资源信息发送给UE2,UE2不再使用该传输资源,重新选取新的传输资源。从而可以解决由于UE2和UE3的隐藏节点问题。
如图12所示,UE2根据侦听选取传输资源,向UE1发送侧行数据,并且预留了时隙1/4/7上的传输资源,由于UE2和UE3距离很远,UE2无法检测到UE3在时隙2/4/6上预留了传输资源。UE1检测到UE2的侧行数据,获取UE2预留的传输资源,同时UE1可以检测到UE3的侧行数据,获取UE3预留的传输资源,即时隙2/4/6上的传输资源,UE1判断在时隙4上UE2和UE3的传输资源发生冲突,因此,UE1将发生冲突的传输资源,即时隙4上的传输资源,发送给UE2,使得UE2避免使用该时隙上的传输资源,即可避免与UE3的传输资源发生冲突,从而避免隐藏节点问题。
可选地,在示例2中,该目标资源集合中的传输资源的侧行RSRP或者侧行RSSI超过第一门限值。
例如,当UE1检测到在传输资源A上存在资源冲突,假设UE1测量UE3在该传输资源A上的侧行RSRP超过第一门限值时,UE1才将该传输资源A发送给UE2,避免UE2选取该传输资源A。假设UE1测量UE3在该传输资源A上的侧行RSRP未超过第一门限值,UE1不发送该传输资源A给UE2,此时,可以认为该传输资源A上UE3对UE2的干扰很低。
需要说明的是,关于第一门限值的描述可以参考上述示例1中的相关描述,在此不再赘述。
可选地,在示例2中,该第二终端设备预留的传输资源中包括该存在冲突的传输资源。
例如,当UE1在某个资源上检测到资源冲突时,UE1向预留该传输资源的终端都发送目标资源集合或第一指示信息。例如,在上述图12中,当UE1检测到UE2和UE3都预留了时隙4上的传输资源,即UE2和UE3会发生资源冲突,UE1向UE2和UE3都发送包括该传输资源的目标资源集合,使得UE2和UE3避免使用该传输资源。
可选地,在示例2中,该第二终端设备为预留了该存在冲突的传输资源的多个终端设备中优先级最低的终端设备。
例如,当UE1在某个资源上检测到资源冲突时,UE1向预留该传输资源的多个终端中优先级等级低的终端发送目标资源集合或第一指示信息。例如,在上述图12中,当UE1检测到UE2和UE3都预留了时隙4上的传输资源,即UE2和UE3会发生资源冲突,UE1检测到UE2的优先级低于UE3的优先级,则UE1向UE2发送包括该传输资源的资源集合,使得UE2避免使用该传输资源,以避免对UE3的干扰。
示例3,该目标资源集合中的传输资源包括与接收端终端的传输资源在时域上存在重叠的传输资源。
例如,UE1向UE2发送目标资源集合,当UE1是UE2发送的侧行数据的接收端终端时,该目标资源集合中的元素包括与UE1的传输资源在时域上有重叠的传输资源。当UE3是UE2发送的侧行数据的接收端终端时,该目标资源集合中的元素包括与UE3的传输资源在时域上有重叠的传输资源。
可选地,在示例3中,该目标资源集合中的传输资源为该接收端终端使用或者预留的传输资源。
例如,当UE1是UE2发送数据的接收端终端时,如果UE2在UE1发送数据的时隙同时发送数据,则由于半双工的限制,UE1无法接收UE2发送的数据。因此,UE1可以将其使用或者预留的传输资源(即将要进行数据传输的资源)发送给UE2,UE2在进行资源选取时,避免使用这些传输资源所在的时隙中的资源,从而可以避免半双工的问题。
例如,如图13所示,UE1和UE2之间进行单播通信,UE1预留了时隙1/4/7上的传输资源,UE1将包括这三个传输资源的资源集合发送给UE2,UE2在进行资源选取时,避免使用该三个传输资源所在的时隙上的传输资源,即UE2避免选取时隙1/4/7上的传输资源,从而避免半双工的问题。
又例如,如图14所示,UE2和UE3之间进行单播通信,UE1可以检测到UE2和UE3发送的侧行数据,获知UE2预留了时隙4/7上的传输资源3、4,UE3预留了时隙4/7上的传输资源1、2,并且根据SCI中包括的地址信息可以确定UE2和UE3之间进行数据通信,UE1将包括传输资源3、4的资源集合发送给UE2,UE2在进行资源选取时,避免使用该两个传输资源所在的时隙上的传输资源,即UE2避免选取时隙4/7上的传输资源,从而避免半双工的问题。或者,UE1将包括传输资源1、2的资源集合发送给UE3,UE3在进行资源选取时,避免使用该两个传输资源所在的时隙上的传输资源,即UE3避免选取时隙4/7上的传输资源,从而避免半双工的问题。
可选地,在示例3中,该目标资源集合中的传输资源为该接收端终端使用或者预留的传输资源所在的时隙信息。
例如,如上述图13所示,UE2和UE1之间进行单播通信,UE1是UE2发送的侧行数据的接收端,UE1使用或预留了时隙1/4/7上的传输资源,UE1将时隙1/4/7的信息发送给UE2,UE2避免使用这3个时隙上的传输资源。
又例如,如上述图14所示,UE2和UE3之间进行单播通信,UE1可以检测到UE2和UE3发送的侧行数据,获知UE2预留了时隙4/7上的传输资源3、4,UE3预留了时隙4/7上的传输资源1、2,并且根据SCI中包括的地址信息可以确定UE2和UE3之间进行数据通信,UE1将包括传输资源3、4的时隙信息,即时隙4/7,发送给UE2,UE2在进行资源选取时,避免使用这两个时隙上的传输资源,即UE2避免选取时隙4/7上的传输资源,从而避免半双工的问题。或者UE1将包括传输资源1、2的时隙信息,即时隙4/7,发送给UE3,UE3在进行资源选取时,避免使用这两个时隙上的传输资源,即UE3避免选取时隙4/7上的传输资源,从而避免半双工的问题。
可选地,在示例3中,该接收端终端是该第二终端设备的接收端终端。例如,第二终端设备是发送端,接收端终端(如第三终端设备或第一终端设备)是第二终端设备的接收端设备。
可选地,在示例3中,该第二终端设备的优先级低于该接收端终端待发送的侧行数据的优先级。例如,发送端(第二终端)和接收端设备都有数据要发送,并且发送端的优先级低于接收端的优先级,则向发送端发送指示信息指示接收端设备要使用的传输资源,避免发送端设备选取这些传输资源。
示例4,该目标资源集合中的传输资源包括该第一终端设备待接收的至少一个PSFCH所占用的时隙信息;或者,该目标资源集合中的传输资源包括第一时隙,该第一时隙中传输的PSSCH对应的PSFCH在第二时隙中传输,该第一终端设备在该第二时隙中存在待接收的至少一个PSFCH。
需要说明的是,当侧行反馈被激活时,接收端终端需要根据接收到的侧行数据的状态向发送端终端发送侧行反馈信息,承载在PSFCH信道中,为了降低PSFCH信道的开销,定义在每N个时隙中的一个时隙包括PSFCH传输资源,即侧行反馈资源的周期是N个时隙,其中N=1、2、4,参数N是预配置或者网络配置的,当终端在时隙n接收到PSSCH时,其对应的PSFCH信道在时隙n+k之后的第一个包括PSFCH传输资源的时隙中传输,其中k是2或3。
例如,如图15所示,k=2,N=4,时隙2、3、4、5中传输的PSSCH,其反馈信息都是在时隙7中传输的,因此可以把时隙{2、3、4、5}看做一个时隙集合,该时隙集合中传输的PSSCH,其对应的PSFCH是在相同的时隙中。
需要说明的是,当UE1在时隙中需要接收PSFCH时,UE1在该时隙上无法发送PSFCH。因此,如果UE1可以确定在某个时隙中需要接收PSFCH,则UE1可以将该时隙信息发送给UE2,UE2在进行资源选取时,避免选取该PSFCH时隙所对应的PSSCH时隙集合中的传输资源。
例如,在上述图15中,如果UE1需要在时隙7中接收PSFCH,例如,UE1在时隙2中向UE2(或其他终端,如UE3)发送了PSSCH,UE2(或UE3)需要在时隙7发送PSFCH,即UE1需要在时隙7接收PSFCH,此时UE1无法在该时隙7上发送PSFCH,因此,UE1可以将时隙7的信息,即需要接收PSFCH的时隙,发送给UE2,UE2在选取资源时,避免选取时隙7对应的PSSCH的时隙,即时隙2/3/4/5上的传输资源。
可选地,在示例4中,该第一终端设备向该第二终端设备发送第二优先级信息,该第二优先级信息为该待接收的至少一个PSFCH所对应的优先级,或者,该第二优先级信息为该待接收的至少一个PSFCH中对应的最高优先级。相应的,该第二终端设备接收该第一终端设备发送的该第二优先级信息。
需要说明的是,终端设备在某个时隙上需要同时发送和接收PSFCH信道,终端设备会根据发送PSFCH和接收PSFCH信道的优先级确定发送PSFCH还是接收PSFCH,如果需要发送的PSFCH的 优先级高,则发送PSFCH,如果接收的PSFCH的优先级高,则接收PSFCH。例如,UE1在时隙A上存在待接收的PSFCH,UE1将需要接收PSFCH的时隙信息发送给UE2,并且将该时隙A中需要接收的PSFCH的优先级信息发送给UE2,UE2可以根据优先级信息确定是否需要在该时隙A对应的PSSCH时隙中进行数据传输。例如,如果UE2需要发送的侧行数据的优先级高于UE1发送给UE2的优先级,则UE2可以选取该时隙A对应的PSSCH时隙进行数据传输,此时,由于UE1接收到UE2的侧行数据,并且该侧行数据对应的优先级(即针对该侧行数据的PSFCH的优先级)高于待接收的PSFCH的优先级,因此UE1会向UE2发送针对该PSSCH的PSFCH,而不接收PSFCH。如果UE2需要发送的侧行数据的优先级低于UE1发送给UE2的优先级,则UE2不选取该时隙A对应的PSSCH时隙进行数据传输,因为,即使UE2选取了该时隙A对应的PSSCH时隙进行数据传输,由于该侧行数据对应的优先级(即针对该侧行数据的PSFCH的优先级)低于待接收的PSFCH的优先级,UE1会接收PSFCH,而放弃向UE2发送针对该PSSCH的PSFCH。
示例5,该目标资源集合中的传输资源包括该第一终端设备待发送的至少一个PSFCH所占用的时隙信息;或者,该目标资源集合中的传输资源包括第三时隙,该第三时隙中传输的PSSCH对应的PSFCH在第四时隙中传输,该第一终端设备在该第四时隙中存在待发送的至少一个PSFCH。
需要说明的是,终端设备同时能够发送PSFCH信道的个数取决于终端的能力,根据终端能力的不同,支持同时发送的PSFCH信道的个数也不同,例如,终端设备可以同时发送N(N=1/2/4/8)个PSFCH信道,当UE1在时隙A要发送的PSFCH已经达到最大值时,UE1可以将该时隙A的信息发送给UE2,UE2在进行资源选取时,避免选取该时隙A所对应的PSSCH时隙集合中的传输资源。
例如,在上述图15中,如果UE1最多支持同时发送2个PSFCH信道,当UE1在时隙7要发送的PSFCH信道个数已经达到或超过2个时,UE1将时隙7的信息发送给UE2,UE2在进行资源选取时,避免选取侧行反馈时隙7所对应的PSSCH时隙,即时隙2/3/4/5上的传输资源。
可选地,在示例5中,该第一终端设备向该第二终端设备发送第二指示信息,该第二指示信息用于指示该待发送的至少一个PSFCH中PSFCH的数量,或者该第二指示信息用于指示该第一终端设备在该待发送的至少一个PSFCH的时隙中还能发送的PSFCH的数量。相应的,该第二终端设备接收该第一终端设备发送的该第二指示信息。
需要说明的是,如果UE1和UE2在建立单播链路时已经交互了终端能力信息,UE2可以获知UE1同时发送PSFCH的个数,因此,UE2可以结合UE1能够支持的发送最大PSFCH的个数以及在时隙A上将要发送的PSFCH的个数,判断UE1是否还可以在该时隙A上发送PSFCH信道,从而可以决定是否可以选取该时隙A对应的PSSCH时隙上的传输资源。
例如,UE1最多支持同时发送4个PSFCH信道,并且在和UE2建立单播通信链路时已经将其能力信息发送给UE2,在上述图15中,UE1确定在时隙7上将要发送2个PSFCH信道,则UE2可以确定UE1在时隙7上还能发送2个PSFCH信道,因此,UE2在该时隙7对应的PSSCH时隙中,即时隙2/3/4/5,最多传输2个独立的数据块,如果每个数据块没有重传,即UE2最多选取2个时隙传输数据。如果支持PSSCH重传,则UE2在时隙2/3/4/5中最多传输2个独立的数据块,每个数据块可以支持1次或多次重传。如第一个数据块使用时隙2/3发送,第二个数据块使用时隙4/5发送,UE1接收到PSSCH时,由于时隙2/3发送的是相同的数据块,因此,只需要反馈一次PSFCH,时隙4/5发送的是相同的数据块,也只需要反馈一次PSFCH。
可选地,在示例5中,该第一终端设备向该第二终端设备发送第三优先级信息,该第三优先级信息为该待发送的至少一个PSFCH所对应的优先级,或者,该第三优先级信息为该待发送的至少一个PSFCH中对应的最高优先级。相应的,该第二终端设备接收该第一终端设备发送的该第三优先级信息。
需要说明的是,UE2可以根据UE1发送的优先级信息以及当前待传输数据的优先级确定是否需要选取PSFCH时隙对应的PSSCH时隙中的传输资源。如果待传输数据的优先级高于UE1发送给UE2的优先级,则UE2可以选取该PSFCH时隙对应的PSSCH时隙进行数据传输,此时,由于UE1接收到UE2的侧行数据,并且该侧行数据对应的优先级(即针对该侧行数据的PSFCH的优先级)高于待发送的PSFCH的优先级,如果同时发送的PSFCH信道的个数没有超过UE1的能力,UE1会同时发送多个PSFCH信道,如果同时发送的PSFCH信道的个数超过UE1的能力,而UE1待发送给UE2的PSFCH信道的优先级更高,因此UE1会向UE2发送针对该PSSCH的PSFCH,而丢弃向其他终端发送的PSFCH。如果UE2需要发送的侧行数据的优先级低于UE1发送给UE2的优先级,则UE2不选取该PSFCH时隙对应的PSSCH时隙进行数据传输,因为,即使UE2选取了该PSFCH时隙对应的PSSCH时隙进行数据传输,由于该侧行数据对应的优先级(即针对该侧行数据的PSFCH的优先级)低于UE1待发送给其他终端的PSFCH的优先级,UE1会向其他终端发送PSFCH,而放弃向UE2发 送针对该PSSCH的PSFCH。
因此,在本申请实施例中,第一终端设备向第二终端设备发送目标资源集合,从而第二终端设备可以根据目标资源集合确定候选传输资源,进而第二终端设备能够在资源选取中避免出现隐藏节点、半双工等问题,提升了资源选取的可靠性。或者,第一终端设备根据目标资源集合向第二终端设备发送第一指示信息,从而第二终端设备可以根据第一指示信息进行资源重选,进而第二终端设备能够在资源选取中避免出现隐藏节点、半双工等问题,提升了资源选取的可靠性。
