Description

通信方法和通信装置 技术领域
本申请涉及通信领域，并且更具体的，涉及通信领域中的通信方法和通信装置。
背景技术
车联网作为未来智能交通运输系统(intelligent transport system，ITS)的关键技术，近来受到了越来越多的关注。其中车与任何设备(vehicle-to-everything，V2X)的系统是车联网中的一个关键技术。V2X其包括了车与车(vehicle-to-vehicle，V2V)、车与路侧基础设施(vehicle-to-infrastructure，V2I)、车与行人(vehicle-to-pedestrian，V2P)的直接通信，以及车与网络(vehicle-to-network，V2N)的通信交互。除V2N车辆和网络通信使用上下行链路，其余V2V/V2I/V2P数据通信均使用侧行链路(sidelink，SL)进行通信。
在V2X系统中，对于一个终端设备而言，会有来自很多其他终端设备发送的信号到达此终端设备的接收机。此时，理想的情况是终端设备需要解出所有可能地到达该终端设备的接收机的数据包。但是，出于终端设备的实现复杂度的、成本以及功率消耗的约束，终端设备不能保证解调出所有潜在到达的数据包。
因此，亟需一种方案，能够在这种情况下尽可能地减少漏检数据包的数量，降低漏检带来的损失。

4)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个，例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C、A和B、A和C、B和C、或A和B和C。“和/或”，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，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。

下面介绍本申请实施例所应用的网络架构。请参考图2，为本申请实施例所应用的一种网络架构。
可参考图2，为一种V2X的网络架构示意图。图2中包括三个终端设备和四个网络设备，其中，三个终端设备分别为UE1、UE2和UE3，四个网络设备分别为两个基站，一个RUS和一个全球导航卫星系统(global navigation satellite system，GNSS)。基站在不同的 系统对应不同的设备，例如在第四代移动通信技术(the 4th generation，4G)系统中可以对应eNB，在5G系统中对应5G中的gNB。V2X终端设备，也可以称为车载设备，车载设备之间可以相互通信，实现信息交流与信息共享，如包括车辆位置、行驶速度等车联状态信息，可用于判断道路车流状况。RSU可以与各个车载设备和/或基站设备通信，进可用于检测道路路面状况，引导车辆选择最佳行驶路径。基站与各个车载设备和/或RSU通信，GNSS可以为其他的网元提供定位授时的信息。此外，该车联网中车载设备还可以与人通信，具体的用户可以通过WiFi、蓝牙、蜂窝等无线通信手段与车辆进行信息沟通，使用户能通过对应的移动终端设备监测并控制车辆。这三个UE和RUS均可以在两个基站覆盖下，每一个基站都可以与这三个UE和RUS进行通信。图2中的基站是可选的，如果有基站，则是有网络覆盖的场景；如果无基站设备则是属于无网络覆盖的场景。
需要说明的是，图2中的终端设备的数量只是举例，在实际应用中，网络设备可以为多个终端设备提供服务。图2中的终端设备可以是V2X终端设备，例如为车载终端设备或车辆为例，但本申请实施例中的终端设备不限于此。
上述各设备之间都可以通过侧行链路和上下行链路进行相互通信，通信时可以使用蜂窝链路的频谱，也可以使用5.9GHz附近的智能交通频谱或者6GHz以上的高频段上的频谱。各设备相互通信的技术可以基于通信网络协议(如LTE协议)进行增强，可以基于D2D技术进行增强。
下面结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供一种通信方法，请参见图3，为该方法的流程图。在下文的介绍过程中，以该方法应用于图2所示的网络架构为例。另外，该方法可由第一终端装置执行，这个终端装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置(例如芯片系统)。
为了便于介绍，在下文中，以该方法由第一终端装置执行为例。例如，下文中第一终端装置可以是图2中的终端设备中的任意一个终端设备，例如车载设备等，或者网络设备。需要说明的是，本申请实施例只是以通过第一终端装置执行为例，并不限制于这种场景。同理，第二终端设备可以是可以是图2中的终端设备中的任意一个终端设备，例如车载设备等，或者网络设备。但是本申请实施例并不限于此。
具体地，请参见图3，为该方法的流程图该方法的流程描述如下。
S310，第一终端装置根据第一参数确定接收能力参数和/或发送能力参数。示例性的，接收能力参数用于表示该第一终端装置的接收能力，发送能力参数用于表示该第一终端装置的发送能力。
本申请实施例中，第一参数包括以下中的一种或多种：初传和最后一次重传的时隙之间的最大间隔，子载波间隔(subcarrier spacing，SCS)，子带大小。其中，第一参数是预配置的，或该第一参数是网络设备配置的，本申请实施例对此不做限定。另外，该第一参数可以用于侧行链路传输，或蜂窝链路，本申请实施例对此不做限定。
作为示例，接收能力参数可以为V2X高接收能力(V2X high reception capability)，或者中等接收能力，或者较低的接收能力，或者V2X缺省接收能力(V2X default reception capability)，但是本申请并不限于此。
本申请实施例中，接收能力参数包括第一时间间隔内能够接收的信道数量，和/或，最 大接收比特数。
示例性的，第一参数(比如初传和最后一次重传的时隙之间的最大间隔，SCS，子带大小中的至少一种)的取值能够影响到第一时间间隔上最大可并行接收的信道数量，和/或，最大接收比特数，从而使得第一终端装置具有该取值对应的接收能力值(接收能力参数的示例)。例如，SCS越大，在固定带宽值下，第一终端装置能够承载的并行接收的信道数量会越小。又例如，子带大小越大，在固定带宽值下，第一终端装置能够承载的并行接收的信道数量会越小。又例如，第一时间间隔的大小，能够影响第一终端装置需要接收的时隙的数量。示例性的，第一时间间隔越大，第一终端装置需要接收的时隙的数量越多，对应的接收能力参数越大。
因此，在本申请实施例中，第一终端装置能够根据初传和最后一次重传的时隙之间的最大间隔，子载波间隔，子带大小中的至少一种确定接收能力参数，能够使得第一终端装置在相应参数值下确定出相应的接收能力值，从而在有来自很多其他终端设备发送的信号到达该第一终端装置的接收机时，有助于使得该第一终端装置能够解出所有可能地到达该终端设备的接收机的数据包，进而有助于尽可能地减少因为不合理的限制，漏掉部分未检测数据包带来的损失，有利于在终端的成本和性能之间达到一个最佳的平衡点。
这里，第一时间间隔内能够接收的信道数量还可以理解为，该第一时间间隔内能够接收的用户数量。一些可选的实施例中，接收能力参数还可以包括第一时间间隔内能够接收的信道数量以及该第一时间间隔内能够接收的信道数量对应的能够检测到的资源块(resource block，RB)数量(也可以称为第一时间间隔内能够接收的信道数量对应的RB数量)。
作为示例，第一时间间隔内能够接收的信道例如为物理侧行链路控制信道(physical sidelink control channel，PSCCH)，但是本申请实施例并不限于此。
在一些可选的实施例中，能够接收的信道数量包括能够接收到的控制信道的数量和/或控制信道对应的数据信道的数量。
在一些可选的实施例中，接收能力参数可以包括在第一时间间隔能够接收的控制信道的数量和对应的能够接收的RB数量，和/或数据信道的数量和对应的能够接收的RB的数量。
可选的，时隙中出现的PSCCH还包括第一级PSCCH和/或第二级PSCCH。也就是说，可选的，在第一时间间隔能够接收的PSCCH的数量可以包括第一级PSCCH的数量和/或第二级PSCCH的数量。
在一些可选的实施例中，接收能力参数可以包括在第一时间间隔能够接收的第一级PSCCH的数量和其对应的能够接收的RB数量，和/或第二级PSCCH的数量和其对应的能够接收的RB的数量。
在一些可选的实施例中，上述第一时间间隔为一个时隙，或为小于或等于一个数据包的初传和最后一次重传之间的间隔，或者为其他信令配置或预定义的时长。
一种可能的情况，一个数据包的初传和重传为基于盲重传的初传和重传。盲重传指的是发送端在向接收端发送数据包时，每个数据包的发送次数为信令指示的、或配置的、或预先定义的、或预配置的，并且接收端不需要向发送端反馈数据包的是否成功接收的状态或结果。也就是说，在基于盲重传的数据传输过程中，发送端只需要相应的发送次数向接 收端发送数据包，并不需要获知接收端是否接收到该数据包。比如发送端可以向接收端连续发送4次相同的数据包，接收端在接收到该数据包时，不需要向发送端发送确认(ACK)，或者接收端在预设时间内没有接收到该数据包时，不需要向发送端发送非确认(NACK)。
另一种可能的情况，上述初传和重传为基于混合自动请求重传(hybrid automatic repeat request，HARQ)的初传和重传。HARQ传输指的是发送端在向接收端发送数据包时，接收端需要向发送端反馈数据包的是否成功接收的状态或结果。也就是说，在基于HARQ传输的过程中，发送端在向接收端发送一个数据包之后，如果接收到了来自接收端的NACK指示，则继续发送该数据包。如果发送端接收到了来自接收端的ACK指示，则停止发送该数据包。
一些可能的实现方式中，在基于HARQ的数据传输中，可以预先定义一个数据包的最大重传次数。例如，在NR系统中，同一个数据包支持最大32次的重传。在实际通信过程中，基于HARQ的传输的重传次数可以在最大重传次数之内进行配置或指示。
一些可选的实施例，可以分别为盲重传和HARQ重传定义支持的最大进程数。
一个示例，盲重传支持的最大进程数可以为4，8或16，或者其他，本申请实施例对此不做限定。
一个示例，在基于HARQ的数据传输中，终端设备需要检测多个通信装置的数据，因此需要定义终端设备支持的最大的HARQ进程个数。例如，在NR系统中，支持最大16个HARQ的进程数。其中，每个HARQ进程可以对应从其他通信装置接收的数据，或向其他通信装置发送的数据。
可选的，终端设备支持的总的最大HARQ进程的个数与终端设备能够接收的总的信道数量相同。换句话说，可选的，当终端设备支持多个HARQ进程，且该终端设备能够接收多个信道时，该多个HARQ进程与该多个信道数量一一对应。
或者，可选的，终端设备支持的最大HARQ进程的个数与终端设备能够支持的接收用户数量相同。换句话说，当终端设备支持多个HARQ进程，且该终端设备能够支持多个接收用户时，该多个HARQ进程与该多个接收用户一一对应。
在本申请实施例以下的描述中，在第一时间间隔上定义终端设备的检测能力时，按终端设备支持的最大控制信道数来描述。可选的，当用于D2D链路时，控制信道可以为PSCCH。在本申请实施例中，终端设备支持的最大控制信道数也可以用来代指终端设备支持的最大的HARQ进程个数，或代指终端设备能够支持的接收用户数量。
本申请实施例中，初传和最后一次重传之间的间隔可以为一个时隙，或者多个时隙，本申请实施例对此不做限定。
一些可能的实现方式，第一时间间隔内能够接收的信道数量小于或等于第一时间间隔中每个时隙上接收的信道数量与第一时间间隔中的时隙个数的乘积。此时，每个时隙上接收的信道数量可以相同，也可以不同的。
在一些实施例中，每个时隙上能够接收的信道总数量可以是相同的，但每个时隙实际接收的信道数量可以是相同的或不同的。作为示例，从终端设备的接收机来看，在每个时隙上，到达每个终端设备上的信道的数量本身就可能是相同或不同的。
作为示例，当终端设备在第一时间间隔中的每个时隙的所有信道都接收数据包时，终端设备在该第一时间间隔内能够接收的信道数量等于该第一时间间隔中每个时隙上接收 的信道数量与第一时间间隔中的时隙个数的乘积。
一个具体的例子，假设终端设备在一个时隙中接收信道数量为M，初传和最后一次重传之间的间隔包括K个时隙，假设所有接收数据的初传和重传(包括HARQ的重传和盲重传)全部译码错误，则终端设备需要为B个信道数量的数据进行缓存(buffer)，其中，B＝M×K，B、M、K均为正整数。
一个示例，对于15kHz的子载波间隔而言，K、M、B的取值可以如下：K＝15，M＝10，B＝M×K＝150。
也就是说，终端设备支持的第一时间间隔内最大能够检测出的总的PSCCH数量为N，其中，N≤B，N为正整数。
一些可能的实现方式中，当第一时间间隔中的多个时隙上接收的信道数量不同时，第一时间间隔内能够接收的信道数量小于或等于第一时间间隔中具有最大或最小接收的信道数量的时隙上的接收信道数量与第一时间间隔中的时隙个数的乘积。示例性的，当第一时间间隔中包括3个时隙，这3个时隙分别对应的接收信道数量为M1＝8、M2＝10、M3＝11，则此时B＝11×3＝33，或者B＝8×3＝24。所以当B＝33时，N值可以取33或小于33的整数，当B＝24时，N值可以取24或小于24的整数。
一些可能的实现方式中，最大接收比特数包括以下至少一种：
一个时隙上的数据信道的传输块上的最大接收比特数(maximum number of bits of a SCH transport block transmitted within a slot)；
一个时隙上的一个数据信道的传输快的最大接收比特数(maximum number of SCH transport block bits transmitted within a slot)；
总的最大接收比特数，即终端设备能够支持的最大的接收比特数。
本申请实施例中，发送能力参数包括最大发送比特数。一些可能的实现方式中，最大发送比特数包括以下至少一种：
一个时隙上的数据信道的传输块上的最大发送比特数(maximum number of bits of a SCH transport block transmitted within a slot)；
一个时隙上的一个数据信道的传输快的最大发送比特数(maximum number of SCH transport block bits transmitted within a slot)；
总的最大发送比特数，即终端设备能够支持的最大的发送比特数。
需要说明的是，本申请实施例中，最大发送比特数/最大接收比特数，主要能够影响第一终端装置设备的缓存大小、数据的处理时间和速度，从而能够影响到第一终端装置的成本、处理时间和功率消耗。
本申请实施例中，第一参数(比如初传和最后一次重传的时隙之间的最大间隔，SCS，子带大小中的至少一种)的取值能够影响到第一时间间隔上最大可并行发送的信道数量，和/或，最大发送比特数，从而使得第一终端装置具有该取值对应的发送能力值(发送能力参数的示例)。例如，SCS越大，在固定带宽值下，第一终端装置能够承载的并行发送的信道数量会越小。又例如，子带大小越大，在固定带宽值下，第一终端装置能够承载的并行发送的信道数量会越小。又例如，第一时间间隔的大小，能够影响第一终端装置需要发送的时隙的数量。示例性的，第一时间间隔越大，第一终端装置需要接收的时隙的数量越多，对应的发送能力参数越大。
因此，本申请实施例中，第一终端装置能够根据初传和最后一次重传的时隙之间的最大间隔，子载波间隔，子带大小中的至少一种来确定发送能力参数，能够使得第一终端装置在相应参数值下确定出相应的发送能力值，从而在有大量数据包待发送时，来自很多其他终端设备发送的信号到达该第一终端装置的接收机时，有助于使得该第一终端装置合理地确定传输数据包的数量和大小，进而有助于尽可能地减少因为不合理的发送缓存大小而丢弃掉待发送的数据包。
一些可能的实现方式中，第一时间间隔内能够接收的信道数量属于至少一种第一时间间隔内能够接收的信道数量。
一些可能的情况，上述子载波间隔属于至少一种子载波间隔，此时上述至少一种第一时间间隔内能够接收的信道数量和该至少一种子载波间隔之间一一对应。且子载波间隔越大，该子载波间隔对应的第一时间间隔内能够接收的信道数量越小。
示例性的，协议中可以定义具有不同的终端设备的接收能力的终端设备，比如两种不同接收能力的终端设备。对于不同接收能力的终端设备而言，相同子载波间隔对应不同的第一时间间隔内能够接收的信道数量。
可选的，第一时间间隔中能够接收的信道数量与SCS的大小严格或近似成反比。和/或，可选的，第一时间间隔内能够接收的信道数量对应的RB数量与SCS的大小严格或近似成反比。
一个示例，表1示出了20MHz带宽下，至少一种SCS对应的两种不同接收能力的终端设备能够检测的信道数量。如表1所示，至少一种SCS例如为15kHz/30kHz/60kHz/120kHz，其中两种能力分别为接收能力1和接收能力2。其中，在表1中，B1所在的列表示接收能力1时，不同的SCS值时对应的各种值下第一时间间隔内能够接收的信道数量，B2所在的列表示接收能力2时，不同的SCS值时对应的各种值下第一时间间隔内能够接收的信道数量。
表1
SCS(kHz) B1 B2 N_RB 1 N_RB2
15 10 20 100 136
30 6 12 50 68
60 2 6 25 34
120 1 3 12 17
在一些实施例中，B1所在的列还可以表示接收能力1时，第一时间间隔内能够接收的第一级控制信道的数量和/或第二级控制信道的数量，B2所在的列还可以表示接收能力2时，第一时间间隔内能够接收的第一级控制信道的数量和/或第二级控制信道的数量。
因此，本申请实施例中，第一终端装置，即接收端设备，可以根据SCS的数值和其支持能力类型(比如接收能力1或接收能力2)，按照预定义的方式(比如表1)来确定该第一终端装置支持的在第一时间间隔内能够接收的信道数量，以便于接收端设备在该SCS数值下确定与其相应接收能力对应接收能力值(即第一时间间隔内能够接收的信道数量)。这样，便于设备厂商在生产相应的设备时，能够按照接收能力值设计相应的架构、计算能力、功率消耗设备成本等，从而在成本与性能之间按相应的能力达到一个较好的平衡。
可选的，当接收能力参数还包括第一时间间隔内能够接收的信道数量对应的能够检测 到的RB数量时，第一时间间隔能够接收的信道数量对应的RB数量属于至少一个第一时间间隔能够接收的信道数量对应的RB数量，此时该至少一个第一时间间隔能够接收的信道数量对应的RB数量与至少一个SCS一一对应。且SCS越大，该SCS对应的第一时间间隔内能够接收的信道数量对应的RB数量越小。并且，对于协议中定义的不同接收能力的终端设备而言，相同SCS对应不同的第一时间间隔内能够接收的信道数量对应的RB数量。
如上表1所示，N_RB1所在的列表示接收能力1时，不同SCS下的第一时间间隔内能够接收的信道数量对应的RB数量，N_RB2所在的列表示接收能力2时，不同SCS下的第一时间间隔内能够接收的信道数量对应的RB数量。
需要说明的是，本申请实施例以20MHz带宽为例进行描述，但本申请实施例并不限于此。比如，带宽还可以为10MHz，或者30MHz，或者其他。
另一个示例，表1a示出了10MHz带宽下，B1、B2、N_RB_1以及N_RB_1相应的取值。在表1a中，不同的SCS值对应两种不同的检测信道的数量B1、B2以及不同的RB数量N_RB1、N_RB2。例如，在表1a的第一列中，当SCS的值为15kHz时，对于接收能力1，检测信道的数量为10，检测的RB数量为50；对于接收能力2，检测信道的数量为20，检测的RB数量为68。又如，在表1a的第一列中，当SCS的值为30kHz时，对于接收能力1，检测信道的数量为6，检测的RB数量为25；对于接收能力2，检测信道的数量为12，检测的RB数量为34。
表1a
SCS(kHz) B1 B2 N_RB 1 N_RB2
15 10 20 50 68
30 6 12 25 34
60 2 6 12 17
120 1 3 6 8
需要说明的是，本申请实施例仅以协议中可以定义2种不同的终端设备的接收能力为例进行描述，但是本申请实施例并不限于此，例如协议中还可以定义1种、3种或更多种不同的终端设备的接收能力，都在本申请实施例的保护范围之内。
因此，本申请实施例中，第一终端装置，即接收端设备，可以根据SCS的数值和其支持的能力类型(比如接收能力1或接收能力2)，按照预定义的方式(比如表1a)来确定该第一终端装置支持的在第一时间间隔内能够接收的信道数量对应的RB数量，以便于接收端设备在该SCS数值下确定与其相应接收能力对应接收能力值(即第一时间间隔内能够接收的信道数量对应的RB数量)。这样，便于设备厂商在生产相应的设备时，能够按照接收能力值设计相应的架构、计算能力、功率消耗设备成本等，从而在成本与性能之间按相应的能力达到一个较好的平衡。
一些可能的情况，上述初传和最后一次重传的时隙之间的间隔属于至少一种初传和最后一次重传的时隙之间的间隔，此时上述至少一种第一时间间隔内能够接收的信道数量和至少一种初传和最后一次重传的时隙之间的间隔一一对应，且初传和最后一次重传的时隙之间的间隔越大，该初传和最后一次重传的时隙之间的间隔对应的第一时间间隔内能够接收的信道数量越大。
可选的，第一时间间隔中能够接收的信道数量与至少一种初传和最后一次重传的时隙之间的间隔中包括的时隙数严格或近似成正比。
