具体实施方式

应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
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(Side Link,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,车联网系统采用终端到终端直接通信的方式,因此具有更高的频谱效率以及更低的传输时延。在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)定义了两种传输模式:模式A和模式B。
图2示出了两种传输模式的示意图。如图2所示,模式A指:终端的传输资源是由基站通过下行链路(Down Link,DL)分配的,终端根据基站分配的资源在侧行链路上进行侧行数据的发送;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,模式B指:车载终端在资源池中选取一个资源进行侧行数据的传输。
在NR-V2X中,需要支持自动驾驶,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NR-V2X系统中,引入了多种传输模式,模式1和模式2,其中,模式1是网络为终端分配传输资源(即对应上述模式A),模式2是终端选取传输资源(即对应上述模式B)。
在NR-V2X中,为了提高传输可靠性,在侧行链路上引入了反馈信道。具体地,图3示出了任意两个车辆之间的数据传输的示意图。如图3所示,车辆UE1和车辆UE2构成一个单播链路,UE1向UE2发送侧行数据,UE2根据接收到的侧行数据的检测结果,向UE1发送侧行反馈信息,该反馈信息可以用于指示UE2是否正确接收到该侧行数据,例如,该反馈信息可以为混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)ACK或NACK。UE1接收UE2的反馈信息,决定是否向UE2发送该数据的重传。
在3GPP Rel-15中,为了降低上行数据的传输时延,引入了配置授权(Configured Grant)的传输(或称为免授权传输)方式,其主要包括两种配置授权方式:第一类配置授权(type-1 configured grant)和第二类配置授权(type-2 configured grant)。
第一类配置授权:网络通过无线资源控制(Radio Resource Control,RRC)信令为终端配置传输资源,该RRC信令配置可以包括:时域资源、频域资源、解调用参考信号(Demodulation Reference Signal,DMRS)、功控、调制编码方案(Modulation and Coding Scheme,MCS)、波形(Waveform)、冗余版本(Redundancy Version,RV)、重复次数、跳频、HARQ进程数等在内的全部传输资源和传输参数。当UE接收到该高层参数后,可立即使用所配置的传输参数在配置的时频资源上进行物理上行共享信道(Physical Uplink Shared Channel,PUSCH)传输。
第二类配置授权:采用两步的资源配置方式,首先,由高层参数(例如,ConfiguredGrantConfig)配置包括时频资源的周期、开环功控、波形、冗余版本、重传次数、跳频、HARQ进程数等在内的传输资源和传输参数;然后由下行链路控制信息(Downlink Control Information,DCI)激活第二类配置授权的PUSCH传输,并同时配置包括时域资源、频域资源、DMRS、MCS等在内的其他传输资源和传输参数。UE在接收到高层参数ConfiguredGrantConfig时,不能立即使用该高层参数配置的资源和参数进行PUSCH传输,而必须等接收到相应的DCI激活并配置其他资源和传输参数后,才能进行PUSCH传输。此外,网络可以通过DCI去激活该配置传输,当终端接收到去激活的DCI后,不能再使用该传输资源进行传输。
如果网络为终端分配了配置授权的传输资源,当终端有上行数据要传输时,可以直接使用该传输资源进行传输,而不需要向网络发送调度请求(Scheduling Request,SR)/缓冲区状态报告(Buffer Status Report,BSR)请求传输资源,从而降低时延。
在NR-V2X中,网络可以为发送端终端分配侧行链路的配置授权传输资源,发送端终端在该配置授权传输资源上向接收端终端发送侧行数据,接收端的终端根据检测结果向发送端终端反馈ACK或NACK。如果发送端终端接收到的是NACK,那么需要进行数据重传,但是此时发送端终端该如何进行数据重传目前尚未解决。例如,发送端终端是否可以向网络上报NACK,申请重传资源,还是终端自主进行数据的重传?如果发送端终端向网络上报NACK,那么又该如何获取向网络发送NACK的传输资源?
因此,本申请实施例提出了用于传输侧行数据的方法,可以用于解决上述问题。
图4为本申请实施例提供的一种用于传输侧行数据的方法200的示意性流程图。如图4所示,该方法200可以包括:S210,发送侧行传输资源指示信息以及第一上行传输资源指示信息,即第一终端设备接收网络设备配置的侧行传输资源指示信息以及第一上行传输资源指示信息,该侧行传输资源指示信息用于指示侧行传输资源,该第一上行传输资源指示信息用于指示第一上行传输资源。
应理解,该方法200中的网络设备可以为任意一个网络设备,例如可以为如图1所示的网络设备;该方法200中的第一终端设备可以为任意一个终端设备,例如可以为如图1所示的终端设备,该第一终端设备为侧行数据传输过程中的发送端。为了便于区别,如图2所示,第二终端设备为侧行数据传输过程中的接收端。其中,考虑到侧行数据的接收端的终端设备可以有一个或者也可以有多个,例如,单播传输过程中,一个发送端终端设备对应一个接收端终端设备;而组播传输过程中,一个发送端终端设备可以对应多个接收端终端设备,因此,该第二终端设备可以指任意一个接收端终端设备,或者该第二终端设备也可以表示多个接收端终端设备,本申请实施例并不限于此。
在本申请实施例中,网络设备向第一终端设备发送侧行传输资源指示信息,通过该侧行传输资源指示信息指示侧行传输资源,该侧行传输资源可以用于第一终端设备与第二终端设备之间的数据的传输, 例如,可以用于传输侧行数据信道、侧行控制信道和侧行反馈信道中的至少一个。具体地,侧行传输资源可以动态配置方式进行配置,或者,也可以通过半静态方式进行配置。
例如,该第一终端设备接收网络设备配置的侧行传输资源指示信息,可以包括:该第一终端设备接收该网络设备发送的配置授权信息,该配置授权信息包括该侧行传输资源指示信息。具体地,通过配置授权信息配置该侧行传输资源,该侧行传输资源即为侧行配置授权传输资源,根据配置授权的方式,该侧行配置授权传输资源可以是第一类(type-1)或者是第二类(type-2)类型的配置授权传输资源,其中type-1配置授权是通过RRC信令配置的,RRC信令包括配置授权的传输资源和传输参数;type-2配置授权是先通过RRC信令配置,该RRC信令可以配置部分配置授权的传输参数,并且通过DCI信令激活或者去激活的,在DCI信令中还可以包括配置授权的传输资源和部分传输参数。应理解,无论采用哪种资源分配方式,本申请实施例中网络设备发送的侧行传输资源指示信息可以包括以下信息中的至少一个:侧行数据信道的参数信息、侧行控制信道的参数信息、侧行反馈信道的参数信息、第二上行传输资源指示信息。下面分别针对每类参数进行详细描述。

具体地,该侧行数据信道的时域资源参数可以包括以下参数中的至少一种:侧行数据信道的周期信息、时隙信息(例如时隙索引,或相对于系统帧号(System Frame Number,SFN)#0的偏移量)、每个时隙中占据的时域符号信息。
侧行数据信道的频域资源参数可以包括以下参数中的至少一种:侧行数据信道的起始频域位置、占据的频域大小、侧行数据信道占据的最小频域单元大小,例如,以子带为最小频域单元,一个子带包括4、8、10个物理资源块(Physical Resource Block,PRB)。
侧行数据信道的DMRS可以包括以下信息中的至少一种:DMRS的图案、DMRS序列的加扰ID信息、DMRS占据的时域符号个数、DMRS占据的时域符号位置。如果侧行数据信道的DMRS在时域支持至少一种图案(pattern),则可以在侧行传输资源指示信息或者说配置授权信息中指定使用某一种DMRS图案。
侧行数据信道的传输方式可以包括以下至少一种:单端口传输、空频分组码(Space Frequency Block Code,SFBC)、循环延迟分集(Cyclic Delay Diversity,CDD)、循环预编码(Pre-coder cycling)。如果侧行链路支持至少一种传输方式,网络设备可以在侧行传输资源指示信息或者说配置授权信息中指定使用某一种传输方式。
侧行数据信道的传输层数可以分为一层传输或是两层传输,或者也可以分为其他多层传输。
MCS可以包括侧行数据使用的MCS等级。
最大传输次数或者也可以称为重复次数,可以用于指示每个侧行数据包(即一个传输快TB)的最大传输次数,例如,可以包括首次传输和重传。
冗余版本(RV)信息可以包括:如果侧行数据信道包括多次传输,每次传输对应的冗余版本信息。例如,冗余版本的顺序为[0 2 3 1],分别对应四次传输(1次首次传输和3次重传),如果数据的传输次数大于4次,则重复使用上面的冗余版本。
HARQ进程数可以指侧行数据信道支持的HARQ进程数。
功控信息可以指示侧行数据信道基于下行路损进行功控或是基于侧行链路的路损进行功控;或者,功控信息也可以指示侧行控制信道和侧行数据信道的功率偏差、或功率谱密度偏差等信息。
侧行数据的大小可以为侧行数据的传输块的大小。
接收侧行数据的终端设备的标识信息也就是目的地标识信息,指的是侧行数据的目的地标识,该标识信息例如可以是作为接收端的第二终端设备的标识信息、组标识信息或和V2X通信的目的地索引。
优先级信息:只有对应该优先级的侧行数据或业务才能在该侧行传输资源指示信息指示的侧行传输资源上传输,或者优先级高于或者等于该优先级信息的侧行数据或业务可以在侧行传输资源指示信息指示的侧行传输资源上传输。例如,假设优先级等级表示为邻近业务每数据包优先级(Prose Per Packet Priority,PPPP),取值范围是[0,7],PPPP取值越低表示优先等级越高。以网络设备向终端设备发送配置授权为例,若网络设备配置的优先级信息为3,表示只有优先等级PPPP为3的侧行数据才可以在该配置授权资源上传输,或者具有更高优先等级,即优先等级PPPP为0、1、2、3的侧行数据可以在该 配置授权资源上传输。
时延信息:只有对应该时延信息的侧行数据或业务才能在网络设备配置的侧行传输资源上传输,或者时延要求高于或者等于该时延信息的侧行数据或业务可以在该侧行传输资源上传输。例如,以网络设备向终端设备发送配置授权为例,若网络设备发送的配置授权的时延信息为10ms,即表示只有时延需求为10ms的侧行业务,或者时延需求更高(如3ms,5ms)的侧行业务可以在该配置授权资源上传输。
CBG反馈指示信息用于确定侧行数据是否支持基于CBG的反馈。例如,该指示信息为1表示支持基于CBG的反馈,即作为侧行数据的接收端的第二终端设备需要针对每个CBG反馈HARQ ACK或NACK;如果该指示信息为0表示不支持基于CBG的反馈,即第二终端设备针对整个传输块(Transmission Block,TB)反馈HARQ ACK或NACK。
CSI-RS的信息可以包括以下至少一个:在侧行数据信道中是否包括CSI-RS、CSI-RS的时域资源、CSI-RS的频域资源。例如,在侧行数据信道中可以包括CSI-RS,用于作为接收端的第二终端设备进行信道测量,因此可以在网络发送的侧行传输资源指示信息中携带用于指示侧行数据中是否包括CSI-RS信号的指示信息。再例如,在该侧行传输资源指示信息中还可以包括指示CSI-RS占据的时域符号的信息。再例如,CSI-RS的频域资源信息可以包括CSI-RS的频域偏移信息和/或频域资源大小。例如,如果CSI-RS是采用梳状传输,即每m个子载波中包括一个用于传输CSI-RS的子载波,则频域偏移信息用于指示在一个资源块(Resource Block,RB)中第一个用于传输CSI-RS的子载波相对于子载波0的偏移量;另外,该频域资源信息可以包括参数m。
CSI反馈指示信息可以用于指示作为接收端的第二终端设备是否需要反馈信道状态信息,如信道质量指示(Channel Quality Indicator,CQI)、秩指示(Rank Indicator,RI)、侧行参考信号接收功率(Sidelink Reference Signal Received Power,S-RSRP)等。
对于侧行控制信道(例如,物理侧行控制信道(Physical Sidelink Control Channel,PSCCH))的参数信息,可以包括以下信息中的至少一个:该侧行控制信道的时域资源参数、该侧行控制信道的频域资源参数。
具体地,侧行控制信道的时域资源可以包括以下信息中至少一种:侧行控制信道的周期、在每个时隙中的时域符号的起始位置、占据的时域符号的个数。
侧行控制信道的频域资源可以包括以下信息中至少一种:侧行控制信道的频域起始位置,每个侧行控制信道占据的频域资源大小、侧行控制信道的最小频域资源粒度大小,例如,最小频域资源粒度是子带,每个子带包括4、8、10个PRB)。
对于侧行反馈信道(例如,物理侧行反馈信道(Physical Sidelink Feedback Channel,PSFCH))的参数信息,可以包括以下信息中的至少一个:该侧行反馈信道相对于侧行数据信道或侧行控制信道的时间偏移量、该侧行反馈信道的时隙参数、该侧行反馈信道的频域资源参数、是否使能侧行反馈、该侧行反馈信道的反馈方式、该侧行反馈信道的格式。其中,该侧行反馈信道可以用于第二终端设备向第一终端设备反馈侧行数据的接收情况。
具体地,该侧行反馈信道的时隙参数可以包括该侧行反馈信道的时隙位置,例如,可以包括该侧行反馈信道相对于侧行数据信道(例如,PSSCH)或侧行控制信道(例如,PSCCH)的时间偏移量。例如,网络设备可以为第一终端设备和第二终端设备配置侧行反馈信道和其对应的侧行数据信道的时间偏移,例如,如图5所示,假设偏移量K=1,表示第一终端设备在时隙n发送侧行数据,则第二终端设备在时隙n+1发送该侧行数据的反馈信息。再例如,如果每k个时隙中的一个时隙包括可以用于传输反馈信道的传输资源,则网络设备可以配置该参数k,例如,如图6所示,该时隙偏移量参数k=4。
该侧行反馈信道的频域资源参数可以包括网络设备为第一终端设备和第二终端设备配置侧行反馈信道的频域起始位置和/或频域资源的大小(或者说长度)。可选地,侧行反馈信道的频域起始位置和PSCCH或者PSSCH的频域起始位置可以相同,也可以不同。可选地,侧行反馈信道的频域长度可以为预配置的或者由网络设备配置的。
该侧行反馈信道的格式可以包括一种或者多种,例如,在NR-V2X中主要讨论两种侧行反馈信道,即短反馈信道和长反馈信道,则网络设备可以指定反馈信道的格式是短反馈信道还是长反馈信道。其中,短反馈信道通常只占据几个时域符号,例如,如图7所示,短反馈信道可以只占用1个或者2个时域符号,并且位于一个时隙的保护间隔(Guard period,GP)符号之前的时域符号上。而长反馈信道通常可以占据一个时隙中的所有可用于侧行传输的时域符号,或者说,该长反馈信道占用一个时隙内除保护间隔以外的全部可用于侧行传输的时域符号,例如,如图7所示,通常一个时隙的第一个符号用作自动增益控制(Automatic Gain Control,AGC),最后一个符号用作GP,该长反馈信道可以占用一个时隙内除这两个符号外其他全部符号,或者,AGC符号上也可以映射反馈信息。
是否使能侧行反馈也就是支持或不支持侧行反馈(enable/disable)。针对侧行数据,第二终端设备 可以发送反馈信息或不发送反馈信息,如果网络设备配置支持侧行反馈,则第二终端设备需要向第一终端设备发送侧行反馈信息,否则第二终端设备不发送侧行反馈信息。
该侧行反馈信道的反馈方式通常有两种,第一方式是只反馈NACK,第二方式是反馈ACK/NACK,网络设备可以配置采用第一方式或第二方式进行反馈。具体地,对于第一方式,若该第一终端设备与该第二终端设备满足预设门限,在该第二终端设备没有正确接收到侧行数据时,向该第一终端设备发送反馈信息,该反馈信息可以为NACK;在该第二终端设备正确接收到侧行数据时,不向该第一终端设备发送反馈信息。但是若该第一终端设备与该第二终端设备不满足预设门限,该第二终端设备不向该第一终端设备发送反馈信息。即满足预设门限时,第二终端设备检测结果是NACK,就反馈NACK,如果第二终端设备检测结果是ACK,则不发送反馈信息;但若不满足预设门限,第二终端设备不发送反馈信息。
其中,该预设门限可以由网络设备配置;或者,也可以为预配置的,例如,可以为协议规定的;或者,也可以根据业务的服务质量(Quality of Service,QoS)参数确定。
该预设门限可以为距离门限,判断第一终端设备与第二终端设备之间的距离是否满足距离门限,例如,若第一终端设备与任意一个第二终端设备之间的距离小于或者等于距离门限,则表示第一终端设备与第二终端设备之间的距离满足距离门限;相反则不满足。类似的,该预设门限还可以为其他参数,例如,参考信号接收功率(Reference Signal Received Power,RSRP)值,本申请实施例并不限于此。
第二方式为:该至少一个第二终端设备根据是否正确接收到侧行数据,向该第一终端设备发送反馈信息,该反馈信息为ACK或NACK。即如果第二终端设备检测结果是NACK,就反馈NACK,如果第二终端设备检测结果是ACK,就反馈ACK。
例如,图8示出了任意一个通信组的示意图。如图8所示,最大的圆圈内共包括7个UE,假设由UE1发送数据,UE2-UE7接收数据,那么对于采用第一方式进行反馈,当接收端UE2-UE7中各个终端设备和发送端UE1的距离在某个预设的距离范围内时,例如,虚线内的UE2、UE3和UE4三个终端设备,每个终端设备到UE1的距离都在预设距离范围内,那么这三个终端设备根据侧行数据接收状态进行反馈,即如果正确接收正确,则不反馈信息;如果接收错误,则向UE1反馈NACK。而对于在预设距离范围外的终端设备,也就是UE5、UE6和UE7,则都不发送反馈信息。对于采用第二方式进行反馈,该组通信内所有的接收端(UE2-UE7)都根据检测状态发送反馈信息,即正确接收侧行数据,则向UE1反馈ACK,没有正确接收,则向UE1反馈NACK。
在本申请实施例中,网络设备向第一终端设备分配用于传输侧行数据的侧行传输资源,如果第一终端设备不向网络设备发送接收确认信息,网络设备不知道第一终端设备是否已经正确接收该侧行传输资源指示信息,因为第一终端设备只是在侧行链路上发送侧行数据,网络设备无法获知侧行链路的状况,因此无法获知该侧行传输资源指示信息是否已经被第一终端设备正确接收,因此需要第一终端设备向网络发送确认信息。
具体地,网络设备发送的该侧行传输资源指示信息中还可以包括第二上行传输资源指示信息,该第二上行传输资源指示信息用于第一终端设备确定第二上行传输资源,该第二上行传输资源用于该第一终端设备向该网络设备发送针对该侧行传输资源指示信息的反馈信息。
例如,网络设备可以为第一终端设备分配一个物理上行控制信道(Physical Uplink Control Channel,PUCCH)传输资源,或者分配PUSCH传输资源,则第一终端设备可以在该PUCCH或PUSCH上发送侧行传输资源指示信息的反馈信息。
可选地,如果网络设备为第一终端设备分配了该第二上行传输资源指示信息,可以隐式的表示该第一终端设备需要向网络发送确认信息,此时就不再需要再显式指示该第一终端设备向网络设备发送反馈信息;但如果网络设备没有为该第一终端设备分配第二上行传输资源指示信息,则不需要第一终端设备向网络设备发送反馈信息。例如,若该侧行传输资源指示信息包括该第二上行传输资源指示信息,该第一终端设备根据该第二上行传输资源指示信息确定第二上行传输资源,并通过该第二上行传输资源,向该网络设备发送该侧行传输资源指示信息的反馈信息,该侧行传输资源指示信息的反馈信息用于指示该第一终端设备是否正确接收到该侧行传输资源指示信息。相反的,若该侧行传输资源指示信息不包括该第二上行传输资源指示信息,则可以隐式指示第一终端设备不需要向网络设备发送该侧行传输资源指示信息的反馈信息,例如,可以通过将第二上行资源指示信息设置为某个特定值来表示不需要向网络设备发送反馈信息。
在本申请实施例中,网络设备还可以向第一终端设备发送第一上行传输资源指示信息,该第一上行传输资源指示信息用于指示第一上行传输资源,以便于第一终端设备在该第一上行传输资源上,向网络设备发送第一反馈信息,该第一反馈信息用于指示侧行数据是否被正确接收。
具体地,该第一上行传输资源指示信息可以用于确定以下信息中的至少一个:该第一上行传输资源 的周期信息、该第一上行传输资源所在时隙的位置信息、该第一上行传输资源在时隙内占用的时域符号的位置信息、该第一上行传输资源在时隙内占用的时域符号的个数信息、该第一上行传输资源的频域信息。
该第一上行传输资源的周期信息可以用于第一终端设备确定第一上行传输资源的周期。可选地,网络设备为第一终端设备分配的侧行传输资源一般为具有周期性的多个侧行传输资源,可以针对每个侧行传输资源设置有一个对应的第一上行传输资源,其中,该第一上行传输资源与该侧行传输资源的周期大小可以设置为相同。
该第一上行传输资源所在时隙的位置信息用于指示该第一上行传输资源所在的时隙。例如该位置信息可以为相对于SFN#0(System Frame Number,系统帧号)的时隙偏移量,或者相对于PSCCH、PSSCH或者物理侧行反馈信道(Physical Sidelink Feedback Channel,PSFCH)的时隙偏移量。
可选地,该第一上行传输资源指示信息用于确定该第一上行传输资源所在时隙的位置信息,具体的,可以通过下面的方式确定:终端接收网络发送的侧行传输资源指示信息,该侧行传输资源指示信息中包括该第一上行传输资源指示信息,终端根据该侧行传输资源指示信息和该第一上行传输资源指示信息确定该第一上行传输资源的时域位置。
具体的,该第一上行传输资源指示信息可以为时间间隔指示信息,例如,该时间间隔指示信息指示的时间间隔可以是与侧行传输资源指示信息或者侧行传输资源相关的时间间隔。对应的,终端设备可以根据该时间间隔指示信息,以及侧行传输资源指示信息,确定第一上行传输资源的时域位置,例如可以确定该第一上行传输资源所在时隙的位置信息。
例如,对于动态调度的侧行传输资源分配方式,即本申请实施例中的侧行传输资源指示信息为通过动态调度配置的,网络可以通过DCI分配侧行传输资源;另外,在该DCI中可以同时指示PUCCH的传输资源,该PUCCH用于终端向网络上报侧行反馈信息,即该PUCCH的传输资源为本申请中的第一上行传输资源。具体地,该DCI中可以携带时间间隔指示信息,该时间间隔指示信息用于指示PUCCH的时域资源和该DCI的时域资源之间的时间间隔。因此,该终端根据接收该DCI的时间以及该时间间隔指示信息,可以确定第一上行传输资源的时域位置,即可以确定PUCCH的时域位置。
又例如,网络为终端分配第二类侧行配置授权,即本申请实施例中的侧行传输资源指示信息为通过第二类侧行配置授权的方式配置的,该侧行配置授权通过RRC信令和DCI信令结合的方式配置侧行传输资源,该第二类侧行配置授权可以通过DCI激活或去激活。此时,可以在DCI和/或RRC中携带时间间隔指示信息,该时间间隔指示信息用于指示PUCCH的时域资源和该DCI的时域资源之间的时间间隔,即该PUCCH的传输资源为本申请中的第一上行传输资源。终端根据接收该DCI的时间以及该时间间隔指示信息,可以确定第一上行传输资源的时域位置,即可以确定第一个PUCCH的时域资源。进一步的,由于侧行配置授权是周期性的传输资源,即网络为终端配置周期的侧行传输资源,那么在每个侧行传输资源周期内都有对应的PUCCH传输资源。在这种情况下,终端可以根据该第一个PUCCH时域资源在所在周期内的时域位置,确定在之后的侧行传输周期内各自对应的上行传输资源。例如,终端在时隙n收到DCI,用于激活侧行配置授权,该DCI中携带的时间间隔指示信息是10个时隙,周期是100个时隙,那么终端确定侧行传输资源的周期为[n+1,n+100],[n+101,n+200],[n+201,n+300],以此类推。终端可以确定第一个上行传输资源的时隙是n+10,因为侧行传输资源的周期是100个时隙,因此每个周期内的PUCCH的传输资源也间隔100个时隙,即后面侧行传输资源周期内的PUCCH分别位于时隙n+110,n+210,以此类推。
又例如,网络为终端分配第一类侧行配置授权,即本申请实施例的侧行传输资源指示信息为通过第一类侧行配置授权的方式配置的,该侧行配置授权通过RRC信令配置侧行传输资源。在RRC中携带时间间隔指示信息,终端根据该时间间隔指示信息可以确定第一上行传输资源的时域资源,例如,可以确定该第一上行传输资源所在时隙的位置信息。例如,在RRC信令中包括时隙偏移指示信息,该时隙偏移指示信息可以用于确定侧行传输周期的起始位置,在RRC信令中还包括时间间隔指示信息,该时间间隔指示信息可以用于指示第一上行传输资源相对于侧行传输周期起始位置的时间间隔。因此,终端结合该时间间隔指示信息以及侧行传输周期的起始位置,确定第一上行传输资源的时域位置。进一步的,由于侧行配置授权是周期性的传输资源,即网络为终端配置周期的侧行传输资源,在每个侧行传输资源周期内都有对应的上行传输资源。例如,在RRC信令中携带的第一个时间间隔信息是100个时隙,该第一个时间间隔信息用于确定侧行传输资源周期的起始位置,该时域偏移信息是相对于SFN#0的,并且RRC信令中指示的周期信息是200个时隙,因此,可以确定侧行传输资源的周期分别对应时隙[100,299],[300,499],[500,699],以此类推。RRC信令中携带的第二时间间隔指示信息是20,该第二时间间隔指示信息用于确定PUCCH时域资源,因此,终端确定在各个周期内的PUCCH分别位于时隙:120,320,520,以此类推。
该第一上行传输资源在时隙内占用的时域符号的位置信息可以用于指示第一上行传输资源所在时隙内具体占用的符号的位置,例如,该位置信息可以包括该第一上行传输资源在一个时隙内的时域符号的起始位置或者结束位置。
该第一上行传输资源在时隙内占用的时域符号的个数信息可以用于指示该第一上行传输资源在一个时隙内占用的时域符号个数。
可选地,上述第一上行传输资源的时域符号起始位置信息和时域符号个数信息可以通过一个或者多个参数指示,通过该参数既可以确定时域符号起始位置也可以确定占用的时域符号个数,本申请实施例并不限于此。
该第一上行传输资源的频域信息可以用于确定该第一上行传输资源的频域资源起始位置和频域资源长度。可选地,该频域资源起始位置和频域资源长度也可以通过一个参数同时确定,或者也可以通过两个独立的参数分别指示。
图9示出了不同传输资源的时频位置的示意图,如图9所示,网络设备为第一终端设备配置侧行传输资源用于传输侧行数据,例如,该侧行传输资源可以包括图9中的侧行数据的传输资源,可以用于第一终端设备向第二终端设备发送侧行数据信道或者侧行控制信道;网络设备配置的侧行传输资源还可以包括图9中的侧行反馈信道的传输资源,可以用于第二终端设备向第一终端设备反馈侧行数据的接收情况;另外,网络设备也可以为第一终端设备分配第一上行传输资源,即图9中的上行反馈信道传输资源,对每个侧行数据的传输资源分配一个对应的上行反馈信道传输资源,以便于第一终端设备向网络设备反馈侧行数据的接收情况。如图9所示,三组传输资源的时频位置之间可以具有一一对应关系,但本申请实施例并不限于此。
应理解,网络设备向第一终端设备发送该第一上行传输资源指示信息可以包括:网络设备向第一终端设备发送配置授权信息,该配置授权信息可以包括该第一上行传输资源指示信息。
可选地,网络设备向第一终端设备发送的侧行传输资源指示信息和第一上行传输资源指示信息可以位于同一配置授权信息中,即网络设备向第一终端设备发送配置授权信息,该配置授权信息包括该侧行传输资源指示信息和该第一上行传输资源指示信息。
可选地,网络设备向第一终端设备发送的侧行传输资源指示信息和第一上行传输资源指示信息也可以是独立的信令,例如,二者可以位于不同的配置信息中。例如,该第一终端设备接收该网络设备发送的第一配置授权信息,该第一配置授权信息包括该侧行传输资源指示信息;该第一终端设备接收该网络设备发送的第二配置授权信息,该第二配置授权信息包括该第一上行传输资源指示信息。
侧行传输资源指示信息和第一上行传输资源指示信息为独立信令时,二者之间可以具有关联关系。例如,可以在包括侧行传输资源指示信息的第一配置授权信息中包括关联信息,和/或,也可以在包括第一上行传输资源指示信息的第二配置授权信息中包括关联信息;其中,该关联信息用于指示该第一上行传输资源指示信息对应于该侧行传输资源指示信息。再例如,该第二配置授权信息或者第一配置授权信息中包括指示信息,该指示信息用于指示该第一终端设备在该第一上行传输资源上发送针对第一侧行数据的第一反馈信息。
可选地,网络设备也可以指示该第一终端设备不需要进行侧行数据的反馈,那么该网络设备也就不需要为该第一终端设备分配该第一上行传输资源。例如,网络设备可以不向第一终端设备发送该第一上行传输资源指示信息,用于隐式的指示该第一终端设备不需要向网络设备反馈侧行数据的接收情况;或者,该网络设备也可以向第一终端设备发送指示信息,通过该指示信息指示第一终端设备不需要向网络设备反馈侧行数据的接收情况,本申请实施例并不限于此。
如图4所示,该方法200还包括:S220,在侧行传输资源上发送侧行数据,即第一终端设备在该侧行传输资源上,向至少一个第二终端设备发送侧行数据。具体地,当第一终端设备有侧行数据发送时,例如该侧行数据可以包括侧行数据信道和/或侧行控制信道,即该侧行数据可以包括PSCCH和/或PSSCH,该第一终端设备可以在网络设备配置的侧行传输资源上选取一个传输资源发送该侧行数据,按照该侧行传输资源指示信息对应的传输资源和传输参数进行侧行数据的传输。
例如,该第一终端设备在该侧行传输资源上,向该至少一个第二终端设备发送侧行控制信息(Sidelink Control Information,SCI),该侧行控制信息用于调度侧行数据信道,该第一终端设备还可以通过该侧行传输资源传输该侧行数据信道。
可选地,该侧行控制信息还包括以下信息中的至少一种:HARQ进程信息、新数据指示(New Data Indication,NDI)信息以及该侧行反馈信道的参数信息,其中,该侧行反馈信道用于承载针对侧行数据信道的反馈信息。
可选地,第一终端设备通过侧行传输资源向第二终端设备发送侧行数据,例如,向第二终端设备发送侧行控制信道或者侧行数据信道,该第二终端设备还可以向第一终端设备反馈该侧行数据的接收情 况。
图10示出了本申请实施例的方法200的另一示意性流程图,如图10所示,在S220之后,该方法200还可以包括:S221,发送第二侧行反馈信息,即第二终端设备向第一终端设备发送第二反馈信息,以便于第一终端设备接收至少一个第二终端设备发送的第二反馈信息,该第二反馈信息用于指示该侧行数据是否被正确接收。例如,该第二反馈信息是ACK或NACK。
可选地,该第二终端设备可以采用由网络设备配置的侧行传输资源发送该第二反馈信息。但由于网络设备是向第一终端设备发送侧行传输资源指示信息,该侧行传输资源指示信息中可以包括侧行反馈信道的参数信息,因此,该第一终端设备可以向第二终端设备发送该侧行反馈信道的参数信息,以便于第二终端设备通过侧行传输资源传输侧行反馈信道。
可选地,第一终端设备向第二终端设备发送的侧行反馈信道的参数信息可以包括网络设备向第一终端设备发送的侧行反馈信道的参数信息中的全部或者部分,因此,该第一终端设备向第二终端设备发送的侧行反馈信道的参数信息可能包括的信息与网络设备向第一终端设备发送的侧行反馈信道的参数信息相同,为了简洁,在此不再赘述。
例如,第一终端设备向第二终端设备发送的侧行反馈信道参数信息用于第二终端设备根据该侧行反馈信道参数信息确定侧行反馈信道,并通过该侧行反馈信道向第一终端设备反馈侧行数据的接收情况,该侧行反馈信道的参数信息可以包括以下信息中的至少一个:该侧行反馈信道相对于侧行数据信道或侧行控制信道的时间偏移量、该侧行反馈信道的时隙参数、该侧行反馈信道的频域资源参数、是否使能侧行反馈、该侧行反馈信道的反馈方式、该侧行反馈信道的格式。
第二终端设备通过侧行传输资源向第一终端设备发送第二反馈信息,通过该第二反馈信息,该第一终端设备可以确定该侧行数据是否被正确接收。具体地,若至少一个第二终端设备反馈的多个第二反馈信息中包括ACK和NACK,或者该第一终端设备接收到的至少一个第二终端设备发送的全部第二反馈信息都是NACK,则该第一终端设备可以判定该侧行数据未被正确接收,也就是该至少一个第二终端设备中存在没有正确接收到该侧行数据的第二终端设备;若该第一终端设备接收该至少一个第二终端设备中的所有第二终端设备发送的第二反馈信息都是ACK,则该第一终端设备可以判定侧行数据被正确接收,也就是该至少一个第二终端设备全部正确接收到该侧行数据;若该第一终端设备判定该至少一个第二终端设备发送的第二反馈信息中存在不连续发送(Discontinuous Transmission,DTX),则该第一终端设备可以判定该侧行数据未被正确接收,也就是该至少一个第二终端设备中存在没有正确接收到该侧行数据的第二终端设备。
如图4或者图10所示,该方法200还包括:S230,在第一上行传输资源上发送第一反馈信息,即第一终端设备在由第一上行传输资源指示信息指示的第一上行传输资源上,向该网络设备发送第一反馈信息,该第一反馈信息用于指示该侧行数据是否被正确接收。
可选地,该第一反馈信息可以由第一终端设备根据接收到的第二终端设备发送的第二反馈信息确定的。该第一终端设备根据该第二反馈信息,确定该侧行数据是否被正确接收;若该侧行数据没有被正确接收,该第一终端设备确定该第一反馈信息用于指示该侧行数据没有被正确接收;若该侧行数据被正确接收,该第一终端设备确定该第一反馈信息用于指示该侧行数据被正确接收,或者,该第一终端设备在侧行数据被正确接收的情况下,不向网络设备发送该第一反馈信息。其中,该第一终端设备可以按照S221的描述,根据第二反馈信息,确定侧行数据是否被正确接收。
可选地,网络设备接收该第一终端设备发送的该第一反馈信息,并可以根据其配置的第一上行传输资源确定该侧行链路的HARQ进程信息;或者,也可以由第一终端设备将该侧行链路的HARQ进程信息发送给网络设备。
应理解,该第一终端设备在该第一上行传输资源上,向该网络设备发送第一反馈信息,可以包括:该第一终端设备在该第一上行传输资源上,向该网络设备发送PUCCH或者PUSCH,该PUCCH或者PUSCH包括该第一反馈信息。具体地,网络设备向第一终端设备发送的第一上行传输资源指示信息可以用于第一终端设备确定PUCCH的传输资源,第一终端设备可以在该第一上行传输资源上向网络发送PUCCH,该PUCCH中承载该侧行数据的第一反馈信息,如ACK或NACK。
可选地,若该第一反馈信息指示该侧行数据没有被正确接收,如图10所示,该方法200还可以包括:S240,发送重传资源指示信息,即网络设备向第一终端设备发送重传资源指示信息,以便于该第一终端设备接收该网络设备发送的该重传资源指示信息,该重传资源指示信息用于指示重传资源;S250,在重传资源上重传侧行数据,即该第一终端设备在该重传资源上,向该至少一个第二终端设备重传该侧行数据。
可选地,网络设备可以通过动态信令,如DCI,为该第一终端设备分配重传资源,即该DCI包括该重传资源指示信息,以用于第一终端设备进行侧行数据的重传。其中,在该重传资源指示信息中或者 说DCI中可以包括侧行链路的进程信息,用于指示该重传资源指示信息或者DCI分配的重传资源是用于哪个HARQ进程进行重传的。
可选地,第一终端设备通过该重传资源进行侧行数据重传时,该第一终端设备可以向第二终端设备发送SCI,通过该SCI调度侧行数据信道。其中,该SCI中可以包括HARQ进程信息和NDI指示信息,该NDI不翻转,以表示重传。
因此,本申请实施例的用于传输侧行数据的方法,网络设备为终端设备分配的侧行传输资源只用于进行侧行数据的新数据的传输,并在配置该侧行数据的侧行传输资源的同时,也为终端设备配置发送侧行数据的反馈信息的传输资源,以便于终端设备向网络设备反馈侧行数据的传输情况,网络设备在终端设备需要进行侧行数据重传时,可以通过动态分配的重传资源实现,这样可以提高资源的利用率,而且所有的侧行链路的传输资源都由网络设备分配,可以降低干扰。
本申请实施例还提出了一种用于传输侧行数据的方法,网络设备为终端设备分配侧行传输资源,终端设备在该侧行传输资源上进行侧行数据的传输,如果需要进行数据的重传,可以在该侧行传输资源上选取资源进行重传。
具体地,图11示出了本申请实施例的另一种用于传输侧行数据的方法300的示意性流程图。如图11所示,该方法300包括:S310,发送侧行传输资源指示信息,第一终端设备接收网络设备配置的侧行传输资源指示信息,该侧行传输资源指示信息用于指示侧行传输资源集合。
应理解,该方法300中的网络设备可以为任意一个网络设备,例如可以为如图1所示的网络设备;该方法300中的第一终端设备可以为任意一个终端设备,例如可以为如图1所示的终端设备,该第一终端设备为侧行数据传输过程中的发送端。为了便于区别,如图11所示,第二终端设备为侧行数据传输过程中的接收端。其中,考虑到侧行数据的接收端的终端设备可以有一个或者也可以有多个,例如,单播传输过程中,一个发送端终端设备对应一个接收端终端设备;而组播传输过程中,一个发送端终端设备可以对应多个接收端终端设备,因此,该第二终端设备可以指任意一个接收端终端设备,或者该第二终端设备也可以表示多个接收端终端设备,本申请实施例并不限于此。
在本申请实施例中,网络设备向第一终端设备发送侧行传输资源指示信息,通过该侧行传输资源指示信息指示侧行传输资源集合,该侧行传输资源集合中的侧行传输资源可以用于第一终端设备与第二终端设备之间的数据的传输,例如,可以用于传输侧行数据信道、侧行控制信道和侧行反馈信道中的至少一个。具体地,侧行传输资源集合可以动态配置方式进行配置,或者,也可以通过半静态方式进行配置。
应理解,该方法300中的S310可以对应于方法200中的S210中网络设备向第一终端设备发送侧行传输资源指示信息的过程,为了简洁,在此不再赘述。
例如,该网络设备发送该侧行传输资源指示信息的方式,以及该侧行传输资源指示信息可能包括的参数,均可以参照S210中对应部分的说明。例如,该S310中该侧行传输资源指示信息可以包括以下信息中的至少一个:侧行数据信道的参数信息、侧行控制信道的参数信息、侧行反馈信道的参数信息、上行传输资源指示信息,其中,该上行传输资源指示信息对应于方法200中的S210中的第二上行传输资源指示信息,为了简洁,在此不再赘述。
其中,为了便于区别,这里将该方法300中侧行传输资源指示信息指示的侧行传输资源称为侧行传输资源集合,该侧行传输资源集合中的侧行传输资源用于第一终端设备与第二终端设备之间的数据的传输。
应理解,该方法300中的S310与方法200中的S210的区别在于,该网络设备不为第一终端设备分配用于向网络设备发送侧行链路反馈信息的第一上行传输资源,也就是不向第一终端设备发送第一上行传输资源指示信息,因此,第一终端设备也不需要将侧行反馈信息发送给该网络设备。
如图11所示,该方法300还包括:S320,在第一侧行传输资源上发送侧行数据,即该第一终端设备在该侧行传输资源集合中的第一侧行传输资源上,向至少一个第二终端设备发送侧行数据。
应理解,该方法300中的S320可以对应于方法200中的S220,也就是该S320适用于S220中的描述,其中,该第一终端设备在第一侧行传输资源上发送侧行数据,该第一侧行传输资源可以对应于方法200中S220中的侧行传输资源,为了简洁,在此不再赘述。
例如,该侧行数据可以包括PSCCH和PSSCH。该第一终端设备可以向第二终端设备发送SCI,该SCI用于调度侧行数据信道。可选地,该SCI中可以包括侧行反馈信道的参数信息;可选地,在SCI中还可以携带HARQ进程信息和NDI指示信息。
另外,图12示出了本申请实施例的方法300的另一示意性流程图,如图12所示,在S320之后,该方法300还可以包括:S321,发送侧行数据的反馈信息,即第二终端设备向第一终端设备发送反馈信息,以便于第一终端设备接收至少一个第二终端设备发送的反馈信息,该反馈信息用于指示该侧行数据是否被正确接收。例如,该反馈信息可以是ACK或NACK。
应理解,该方法300中的S321可以对应于方法200中的S221,也就是该S321适用于S221中的描述,其中,该第一终端设备可以在侧行传输资源集合中的部分侧行传输资源上发送该反馈信息,该部分侧行传输资源的描述可以对应于方法200中S220中的用于传输第二反馈信息的侧行传输资源的描述;另外,该S321中的反馈信息对应于S221中的第二反馈信息,为了简洁,在此不再赘述。
可选地,若第一终端设备根据第二终端设备反馈的侧行数据的反馈信息,确定该侧行数据未被正确接收,如图11和12所示,该方法300还可以包括:S330,在第二侧行传输资源上重传侧行数据,即若该侧行数据没有被正确接收,该第一终端设备在该侧行传输资源集合中的第二侧行传输资源上,向该至少一个第二终端设备重传该侧行数据。
例如,图13示出了本申请实施例的侧行数据传输的示意图,如图13所示,全部的黑色方块都属于网络设备配置的侧行传输资源集合。这里假设第一终端设备在第一个黑色方块对应的资源上向第二终端设备发送第一侧行数据,该第一个黑色方块对应的资源属于侧行传输资源集合中的第一侧行传输资源;之后假设第一终端设备接收第二终端设备针对该第一侧行数据的反馈信息为NACK,则第一终端设备可以在第二个黑色方块对应的资源上向第二终端设备重传该第一侧行数据,该第二个黑色方块属于侧行传输资源集合中的第二侧行传输资源。假设第一终端设备接收第二终端设备针对第一侧行数据的重传数据的反馈信息为ACK,则该第一终端设备不需要再次进行该第一侧行数据的重传。
另外,假设第一终端设备在第三个黑色方块对应的资源上需要向第二终端设备发送第二侧行数据,该第三个黑色方块对应的资源也属于侧行传输资源集合中的第一侧行传输资源;之后假设终端设备接收第二终端设备针对第二侧行数据的反馈信息为ACK,则该第一终端设备不需要进行该第二侧行数据的重传。那么该第一终端设备可以继续执行其他侧行数据的传输,例如还可以在第四个黑色方块对应的资源上发送第三侧行数据,以此类推,其中,该第四个黑色方块对应的资源也属于侧行传输资源集合中的第一侧行传输资源。
因此,本申请实施例的用于传输侧行数据的方法,网络设备为终端设备配置的侧行传输资源可以用于终端设备进行侧行数据的首次传输,也可以用于重传,由终端设备在配置的侧行传输资源上自主选取用于首次传输和重传的资源,可以降低与网络设备之间的信令开销。
本申请实施例还提出了一种用于传输侧行数据的方法,网络设备为终端设备分配侧行传输资源,终端设备在该侧行传输资源上进行侧行数据的传输,如果需要进行数据的重传,终端设备可以在资源池中获取传输资源进行数据的重传。
具体地,图14示出了本申请实施例的再一种用于传输侧行数据的方法400的示意性流程图。如图14所示,该方法400包括:S410,发送侧行传输资源指示信息,即网络设备向第一终端设备发送侧行传输资源指示信息,第一终端设备接收网络设备配置的侧行传输资源指示信息,该侧行传输资源指示信息用于确定第一侧行传输资源。
应理解,该方法400中的网络设备可以为任意一个网络设备,例如可以为如图1所示的网络设备;该方法400中的第一终端设备可以为任意一个终端设备,例如可以为如图1所示的终端设备,该第一终端设备为侧行数据传输过程中的发送端。为了便于区别,如图14所示,第二终端设备为侧行数据传输过程中的接收端。其中,考虑到侧行数据的接收端的终端设备可以有一个或者也可以有多个,例如,单播传输过程中,一个发送端终端设备对应一个接收端终端设备;而组播传输过程中,一个发送端终端设备可以对应多个接收端终端设备,因此,该第二终端设备可以指任意一个接收端终端设备,或者该第二终端设备也可以表示多个接收端终端设备,本申请实施例并不限于此。
在本申请实施例中,网络设备向第一终端设备发送侧行传输资源指示信息,通过该侧行传输资源指示信息指示第一侧行传输资源,该第一侧行传输资源可以用于第一终端设备与第二终端设备之间的数据的传输,例如,可以用于传输侧行数据信道、侧行控制信道和侧行反馈信道中的至少一个。具体地,该第一侧行传输资源可以动态配置方式进行配置,或者,也可以通过半静态方式进行配置。
应理解,该方法400中的S410可以对应于方法200中的S210中网络设备向第一终端设备发送侧行传输资源指示信息的过程,为了简洁,在此不再赘述。
例如,该网络设备发送该侧行传输资源指示信息的方式,以及该侧行传输资源指示信息可能包括的参数,均可以参照S210中对应部分的说明。例如,该S410中该侧行传输资源指示信息可以包括以下信息中的至少一个:侧行数据信道的参数信息、侧行控制信道的参数信息、侧行反馈信道的参数信息、上行传输资源指示信息,其中,该上行传输资源指示信息对应于方法200中的S210中的第二上行传输资源指示信息,为了简洁,在此不再赘述。
其中,为了便于区别,这里将该方法400中侧行传输资源指示信息指示的侧行传输资源称为第一侧行传输资源,该第一侧行传输资源用于第一终端设备与第二终端设备之间的数据的传输。
应理解,该方法400中的S410与方法200中的S210的区别在于,该网络设备不为第一终端设备 分配用于向网络设备发送侧行链路反馈信息的第一上行传输资源,也就是不向第一终端设备发送第一上行传输资源指示信息,因此,第一终端设备也不需要将侧行反馈信息发送给该网络设备。
如图14所示,该方法400还包括:S420,在第一侧行传输资源上发送侧行数据,即该第一终端设备在该第一侧行传输资源上,向至少一个第二终端设备发送侧行数据。
应理解,该方法400中的S420可以对应于方法200中的S220,也就是该S420适用于S220中的描述,其中,该第一终端设备在第一侧行传输资源上发送侧行数据,该第一侧行传输资源对应于方法200中S220中的侧行传输资源,为了简洁,在此不再赘述。
例如,该侧行数据可以包括PSCCH和PSSCH。该第一终端设备可以向第二终端设备发送SCI,该SCI用于调度侧行数据信道。可选地,该SCI中可以包括侧行反馈信道的参数信息;可选地,在SCI中还可以携带HARQ进程信息和NDI指示信息。
另外,图15示出了本申请实施例的方法400的另一示意性流程图,如图15所示,在S420之后,该方法400还可以包括:S421,发送侧行数据的反馈信息,即第二终端设备向第一终端设备发送第二反馈信息,以便于该第一终端设备接收该至少一个第二终端设备发送的该侧行数据的反馈信息;该第一终端设备根据该反馈信息,确定该侧行数据是否被正确接收。例如,该反馈信息可以是ACK或NACK。
应理解,该方法400中的S421可以对应于方法200中的S221,也就是该S421适用于S221中的描述,其中,该第一终端设备可以在第一侧行传输资源中的部分侧行传输资源上发送该反馈信息,该部分侧行传输资源的描述可以对应于方法200中S220中的用于传输第二反馈信息的侧行传输资源的描述;另外,该S421中的反馈信息对应于S221中的第二反馈信息,为了简洁,在此不再赘述。
可选地,若第一终端设备根据第二终端设备反馈的侧行数据的反馈信息,确定该侧行数据未被正确接收,如图14和15所示,该方法400还可以包括:S430,在资源池中获取第二侧行传输资源;S440,在第二侧行传输资源上重传侧行数据。具体地,若该第一终端设备确定该侧行数据没有被正确接收,该第一终端设备获取资源池配置信息,并根据该资源池配置信息确定资源池;该第一终端设备在该资源池中的第二侧行传输资源上,向该至少一个第二终端设备重传该侧行数据。
可选地,该方法400还可以包括:终端设备在资源池中获取第二侧行传输资源;进一步的,获取第二侧行传输资源还可以包括:该第一终端设备通过资源侦听,在该资源池中获取该第二侧行传输资源;或者,该第一终端设备在该资源池中随机选取一个传输资源作为该第二侧行传输资源。
可选地,该侦听过程可以包括检测PSCCH,进行RSRP测量等,其中RSRP测量可以是测量PSCCH-RSRP或者PSSCH-RSRP,本申请实施例并不限于此。
例如,图16示出了本申请实施例的另一侧行数据传输的示意图,如图16所示,黑色方块对应的资源属于网络设备配置的第一侧行传输资源;具有斜线方格的方块对应的资源属于资源池中的第二侧行传输资源。这里假设第一终端设备在第一个黑色方块对应的资源上向第二终端设备发送第一侧行数据,该第一个黑色方块对应的资源属于第一侧行传输资源;之后假设第一终端设备接收第二终端设备针对该第一侧行数据的反馈信息为NACK,则第一终端设备可以在资源池中获取第二侧行传输资源,例如,可以通过在资源池中侦听的方式,获取第二个方块对应的资源,并在该资源上向第二终端设备重传该第一侧行数据,该第二个方块属于第二侧行传输资源。若第一终端设备接收第二终端设备针对第一侧行数据的重传数据的反馈信息为ACK,则该第一终端设备不需要再次进行该第一侧行数据的重传;但若第一终端设备接收第二终端设备针对第一侧行数据的重传数据的反馈信息仍然为NACK,则第一终端设备可以在资源池中获取第二侧行传输资源,例如,可以通过在资源池中侦听的方式,获取第三个方块对应的资源,并在该资源上向第二终端设备再次重传该第一侧行数据,该第三个方块属于第二侧行传输资源。以此类推,直至第一终端设备接收第二终端设备针对第一侧行数据的重传数据的反馈信息为ACK,或者达到最大重传次数,则停止传输该第一侧行数据。
另外,假设第一终端设备在第四个黑色的方块对应的资源上需要向第二终端设备发送第二侧行数据,该第四个黑色方块对应的资源也属于第一侧行传输资源;之后假设终端设备接收第二终端设备针对第二侧行数据的反馈信息为ACK,则该第一终端设备不需要进行该第二侧行数据的重传。那么该第一终端设备可以继续执行其他侧行数据的传输,例如还可以在第五个黑色的方块对应的资源上发送第三侧行数据,以此类推,其中,该第五个黑色的方块对应的资源也属于第一侧行传输资源。
因此,本申请实施例的用于传输侧行数据的方法,网络设备为终端设备配置的侧行传输资源用于侧行数据的首次传输,如果需要进行重传,该重传数据的传输资源可以由终端设备通过侦听或者其他方式在资源池中获取,即侧行数据的首次传输使用网络设备分配的传输资源,重传使用终端设备自主选取的传输资源,这样,网络设备在配置侧行链路的传输资源时,只需要考虑首次传输就可以,而不需要考虑重传,还可以降低终端设备和网络设备之间的信令开销。
应理解,在本申请的各种实施例中,上述各过程的序号的大小并不意味着执行顺序的先后,各过程 的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
