可选地，UE120之间可以进行设备到设备(Device to Device，D2D)通信。Optionally, device-to-device (Device to Device, D2D) communication may be performed between the UEs 120 .

D2D通信是一种基于侧行链路(SideLink，SL)的传输技术，与传统的蜂窝***中通信数据通过基站接收或者发送的方式不同，D2D通信是采用终端到终端直接通信的方式。在第三代移动通信合作伙伴(Third Generation Partnership Project，3GPP)中，分别通过不同的阶段对D2D通信进行研究；NR-V2X是D2D通信研究的一个阶段。D2D communication is a sidelink (SideLink, SL)-based transmission technology. Different from the traditional cellular system in which communication data is received or sent through a base station, D2D communication adopts terminal-to-terminal direct communication. In the Third Generation Partnership Project (3GPP), D2D communication is studied through different stages; NR-V2X is a stage of D2D communication research.

在3GPP中定义了两种侧行传输模式，分别是模式A和模式B。其中，Two sideline transmission modes are defined in 3GPP, mode A and mode B, respectively. in,

针对模式A：如图1-2所示，终端设备的传输资源是由网络设备分配的，终端设备根据网络设备分配的资源在侧行链路上进行数据的发送；网络设备可以为终端分配单次传输的资源，也可以为终端设备分配半静态传输的资源。For mode A: As shown in Figure 1-2, the transmission resources of the terminal device are allocated by the network device, and the terminal device sends data on the side link according to the resources allocated by the network device; the network device can allocate a single resources for secondary transmission, and resources for semi-static transmission can also be allocated to terminal devices.

针对模式B：如图1-3所示，车载终端在资源池中选取一个资源进行数据的传输。For mode B: As shown in Figure 1-3, the vehicle terminal selects a resource in the resource pool for data transmission.

下面对NR-V2X和LTE-V2X中进行简要说明。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。The following is a brief description of NR-V2X and LTE-V2X. In NR-V2X, autonomous driving needs to be supported, so higher requirements are put forward for data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, More flexible resource allocation, etc.

而在LTE-V2X中，支持广播传输方式、单播传输方式和组播传输方式。对于单播传输方式，如图1-4所示，只有一个接收端的终端设备，UE1与UE2之间进行单播传输。对于组播传输方式，接收端是一个通信组内的所有终设备，或者是在一定传输距离内的所有终端设备。对于组播传输方式，如图1-5所示，UE1、UE2、UE3和UE4构成一个通信组，其中UE1是发送端的终端设备，用于发送数据，该组内的UE2、UE3和UE4都是接收端的终端设备，用于接收数据。对于广播传输方式，接收端可以是任意一个终端设备，如图1-6所示，UE1是发送端的终端设备，用于发送数据，UE1周围的其他终端设备，如UE2、UE3、UE4、UE5、UE6和UE7都是接收端的终端设备，用于接收数据。In LTE-V2X, broadcast transmission, unicast transmission and multicast transmission are supported. For the unicast transmission mode, as shown in Figure 1-4, there is only one terminal device at the receiving end, and unicast transmission is performed between UE1 and UE2. For multicast transmission, the receiver is all terminal devices in a communication group, or all terminal devices within a certain transmission distance. For the multicast transmission mode, as shown in Figure 1-5, UE1, UE2, UE3 and UE4 form a communication group, where UE1 is the terminal device on the sender side and is used to send data. UE2, UE3 and UE4 in the group are all The terminal device at the receiving end is used to receive data. For the broadcast transmission mode, the receiver can be any terminal device. As shown in Figure 1-6, UE1 is the terminal device of the sender, which is used to send data. Other terminal devices around UE1, such as UE2, UE3, UE4, UE5, Both UE6 and UE7 are terminal devices at the receiving end, which are used to receive data.

针对NR-V2X中，包括模式1和模式2两种资源分配方式。在模式2中，终端在资源池自主选取传输资源进行侧行传输，即上述传输模式B。在模式1中，网络设备为终端设备分配侧行传输资源，即上述传输模式A；具体的，网络设备可以通过动态调度(Dynamic Scheduling)的方式为终端设备分配侧行传输资源；或者网络设备可以为终端设备分配侧行配置授权(Configured Grant，CG)传输资源。对于网络设备为终端设备分配侧行CG的资源分配方式，主要包括两种配置授权方式：第一类配置授权(type-1configured grant)和第二类配置授权(type-2 configured grant)；具体的：For NR-V2X, there are two resource allocation methods, mode 1 and mode 2. In mode 2, the terminal autonomously selects transmission resources in the resource pool for sideline transmission, that is, the above-mentioned transmission mode B. In mode 1, the network device allocates sideline transmission resources to the terminal device, that is, the above-mentioned transmission mode A; specifically, the network device may allocate sideline transmission resources to the terminal device by means of dynamic scheduling; or the network device may Allocate sideline configuration grant (CG) transmission resources to terminal devices. For the resource allocation method in which the network device allocates the sideline CG to the terminal device, it mainly includes two configuration authorization methods: the first type of configuration authorization (type-1 configured grant) and the second type of configuration authorization (type-2 configured grant). :

第一类配置授权：网络设备通过无线资源控制(Radio Resource Control，RRC)信令为终端设备配置侧行传输资源，该RRC信令配置包括时域资源、频域资源、DMRS、调制编码方式(Modulation and Coding Scheme，MCS)等在内的全部传输资源和传输参数。当终端设备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侧行传输。The first type of configuration authorization: the network device configures sideline transmission resources for the terminal device through Radio Resource Control (RRC) signaling. The RRC signaling configuration includes time domain resources, frequency domain resources, DMRS, modulation and coding methods ( All transmission resources and transmission parameters including Modulation and Coding Scheme, MCS). When the terminal device receives the high-layer parameters, it can immediately use the configured transmission parameters to perform lateral transmission on the configured time-frequency resources.

第二类配置授权：采用两步的资源配置方式，即网络设备通过RRC信令和下行控制信息(Downlink Control Information，DCI)分配资源的方式；首先，由RRC信令配置包括时频资源的周期、冗余版本、重传次数、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程数等在内的传输资源和传输参数，然后由DCI激活第二类配置授权的传输，并同时配置包括时域资源、频域资源、MCS等在内的其他传输资源和传输参数。终端设备在接收到RRC信令时，不能立即使用该高层参数配置的资源和参数进行侧行传输，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，才能进行侧行传输。此外，网络设备可以通过DCI去激活该配置传输，当终端设备接收到去激活的DCI后，不能再使用该传输资源进行侧行传输。The second type of configuration authorization: a two-step resource configuration method is adopted, that is, the network device allocates resources through RRC signaling and downlink control information (Downlink Control Information, DCI). First, the period including time-frequency resources is configured by RRC signaling. , redundancy version, number of retransmissions, number of Hybrid Automatic Repeat reQuest (HARQ) processes and other transmission resources and transmission parameters, and then the DCI activates the transmission authorized by the second type of configuration, and configures the configuration including Other transmission resources and transmission parameters including time domain resources, frequency domain resources, MCS, etc. When the terminal device receives the RRC signaling, it cannot immediately use the resources and parameters configured by the high-level parameters for sideline transmission, but must wait for the corresponding DCI activation and configure other resources and transmission parameters before performing sideline transmission. In addition, the network device can deactivate the configuration transmission through DCI, and after the terminal device receives the deactivated DCI, it can no longer use the transmission resource for sideline transmission.

如果网络设备为终端设备分配了配置授权的传输资源，当终端设备有侧行数据要传输时，终端设备可以直接使用该传输资源进行传输，而不需要向网络设备发送调度请求(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。If the network device allocates the configuration authorized transmission resource to the terminal device, when the terminal device has sideline data to transmit, the terminal device can directly use the transmission resource for transmission without sending a Scheduling Request (SR) to the network device. )/Buffer Status Report (BSR) to request transmission resources, thereby reducing latency.

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***中引入了多种传输模式，如模式1和模式2；其中，模式1是网络设备为终端设备分配传输资源(即上述传输模式A)，模式2是终端设备选取传输资源(即上述传输模式B)。In NR-V2X, autonomous driving needs to be supported, so higher requirements are put forward for data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, More flexible resource allocation, etc. In the NR-V2X system, a variety of transmission modes are introduced, such as mode 1 and mode 2; among them, mode 1 is that the network equipment allocates transmission resources for the terminal equipment (that is, the above-mentioned transmission mode A), and mode 2 is that the terminal equipment selects transmission resources ( That is, the above-mentioned transmission mode 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，如图1-7所示，其中UE1和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，即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。UE1可以决定是否需要接收端终端UE2发送反馈信息，例如，对于广播通信，不需要接收端进行反馈，对于单播通信，为了提高***的可靠性，接收端需要进行反馈。具体的，UE1在侧行链路控制信息(Sidelink Control Information，SCI)中，携带指示信息，所述指示信息用于指示接收端是否需要进行侧行反馈。In NR-V2X, in order to improve transmission reliability, a feedback channel is introduced on the sidelink, as shown in Figure 1-7, where UE1 and UE2 form a unicast link, and UE1 sends sidelink data to UE2. UE2 sends sideline feedback information, ie ACK or NACK, to UE1 according to the detection result of the received sideline data. UE1 receives the feedback information from UE2, and decides whether to send retransmission of the data to UE2. UE1 can decide whether the receiving terminal UE2 needs to send feedback information. For example, for broadcast communication, the receiving terminal does not need to provide feedback, and for unicast communication, in order to improve the reliability of the system, the receiving terminal needs to provide feedback. Specifically, UE1 carries indication information in sidelink control information (Sidelink Control Information, SCI), and the indication information is used to indicate whether the receiving end needs to perform sidelink feedback.

NR-V2X中用于传输PSSCH的资源中包括用于传输DMRS的资源，该DMRS用于信道估计，从而使得接收端终端能够检测PSSCH。在NR-V2X中，在一个时隙中可以用于SL传输的时域符号个数是7、8、9、…、14，包括AGC时域符号和GP时域符号，在一个时隙中，PSSCH、PSCCH和PSFCH的复用形式如图1-8所示，其中，物理侧行链路控制信道(Physical Sidelink Control CHannel，PSCCH)和PSSCH的频域起始位置对齐，PSCCH占据一个子带中的X个PRB，X小于等于子带的大小，PSCCH从第二个可用的侧行时域符号开始，占据2个或3个时域符号，PSFCH占据一个时隙中可用于侧行传输的时域符号中倒数第二个和倒数第三个时域符号，最后一个时域符号用作GP，PSFCH的两个时域符号中的第一个时域符号可以用作AGC，在PSSCH占据的时域符号的后一个时域符号是GP。其中，1个子带包括频域连续的多个PRB。The resources used for PSSCH transmission in NR-V2X include resources used for transmission of DMRS, and the DMRS is used for channel estimation, so that the receiving terminal can detect the PSSCH. In NR-V2X, the number of time domain symbols that can be used for SL transmission in one slot is 7, 8, 9, ..., 14, including AGC time domain symbols and GP time domain symbols. In one slot, The multiplexing form of PSSCH, PSCCH and PSFCH is shown in Figure 1-8, in which the physical sidelink control channel (Physical Sidelink Control CHannel, PSCCH) is aligned with the starting position in the frequency domain of PSSCH, and PSCCH occupies a subband. X PRBs, X is less than or equal to the size of the subband, PSCCH starts from the second available sideline time domain symbol, occupies 2 or 3 time domain symbols, and PSFCH occupies a time slot that can be used for sideline transmission. The second-to-last and third-to-last time-domain symbols in the domain symbols, the last time-domain symbol is used as GP, the first time-domain symbol of the two time-domain symbols of PSFCH can be used as AGC, when PSSCH is occupied The next time domain symbol to the domain symbol is GP. Among them, one subband includes multiple PRBs that are continuous in the frequency domain.

相关技术中，关于PSSCH DMRS的样式参见图1-9以及图1-10，分别给出PSSCH(图中灰色部分)占用6-13个时域符号的情况下的DMRS图案。In the related art, for the pattern of PSSCH DMRS, see Figures 1-9 and Figures 1-10, which respectively show the DMRS pattern in the case where PSSCH (gray part in the figure) occupies 6-13 time-domain symbols.

PSSCH DMRS在一个时隙中的位置与时隙中可用于侧行链路的符号数量之间的关系如下表1所示：The relationship between the position of the PSSCH DMRS in a slot and the number of symbols available for the sidelink in the slot is shown in Table 1 below:

表1：PSSCH DM-RS时域位置Table 1: PSSCH DM-RS time domain location

可以看出，相关技术中明确了PSSCH占用6-13个时域符号的DMRS图案，其中， PSSCH占用的时域符号包括AGC的时域符号，且不包括最后一个GP符号。但是，若一个时隙中包括传输PSFCH的时域符号，且可用于侧行链路的时域符号的数量为7、或8、或9，去除PSFCH信道占据的2个时域符号，以及PSFCH信道之前的GP符号和时隙中的最后一个用作GP的符号，则可用于传输PSSCH的时域符号的数量分别为3、或4、或5。但是，相关技术中并未针对该场景定义DMRS图案；因此，如何合理、有效地分配一个时隙内的时域符号尚未被明确。It can be seen that the related art specifies a DMRS pattern in which the PSSCH occupies 6-13 time-domain symbols, wherein the time-domain symbols occupied by the PSSCH include the time-domain symbols of the AGC and do not include the last GP symbol. However, if a time slot includes time-domain symbols for transmitting PSFCH, and the number of time-domain symbols available for the sidelink is 7, or 8, or 9, remove the 2 time-domain symbols occupied by the PSFCH channel and the PSFCH If the GP symbol before the channel and the last one in the time slot are used as the GP symbol, the number of time domain symbols that can be used to transmit the PSSCH is 3, or 4, or 5, respectively. However, the DMRS pattern is not defined for this scenario in the related art; therefore, how to allocate time-domain symbols in a time slot reasonably and effectively has not yet been clarified.

步骤S201，第一设备根据一个时隙内用于侧行链路的时域符号的数量，确定在所述时隙内是否传输PSFCH。Step S201, the first device determines whether to transmit the PSFCH in the time slot according to the number of time domain symbols used for the sidelink in the time slot.

在一些实施例中，若所述时隙内用于侧行链路的时域符号的数量小于第一阈值，则所述第一设备在所述时隙内禁止传输所述PSFCH。即在所述时隙内用于侧行链路的时域符号的数量小于第一阈值的情况下，第一设备在所述时隙内不传输所述PSFCH。In some embodiments, the first device prohibits transmission of the PSFCH in the time slot if the number of time domain symbols used for the sidelink in the time slot is less than a first threshold. That is, in the case that the number of time domain symbols used for the sidelink in the time slot is less than the first threshold, the first device does not transmit the PSFCH in the time slot.

在一些实施例中，所述第一阈值小于或等于10，即所述第一阈值的最大值为10，优选的，所述第一阈值等于10。在具体实施时，若所述时隙内用于侧行链路的时域符号的数量小于10，则第一设备在所述时隙内不传输PSFCH。In some embodiments, the first threshold is less than or equal to 10, that is, the maximum value of the first threshold is 10. Preferably, the first threshold is equal to 10. In a specific implementation, if the number of time domain symbols used for the sidelink in the time slot is less than 10, the first device does not transmit the PSFCH in the time slot.

在一些实施例中，所述第一设备可以获取第一配置信息，所述第一配置信息用于配置一个时隙内用于侧行链路的时域符号的数量。其中，所述时域符号可以是正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。In some embodiments, the first device may acquire first configuration information, where the first configuration information is used to configure the number of time domain symbols used for the sidelink in one time slot. The time-domain symbols may be orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols.

在具体实施时，第一设备可以通过协议预定义的方式或预配置的方式获取第一配置信息，也可以由第二设备为第一设备配置第一配置信息，还可以是第一设备与第二设备协商确定第一配置信息。当所述第二设备是网络设备时，第一设备通过接收第二设备发送的第一配置信息，该第一配置信息例如是通过***信息块(System Information Block,SIB)或无线资源控制(Radio Resource Control，RRC)信令承载，该第一配置信息可以是资源池配置信息或带宽分段(BandWidth Part，BWP)配置信息。During specific implementation, the first device may obtain the first configuration information in a protocol predefined manner or a pre-configured manner, or the second device may configure the first configuration information for the first device, or the first device and the first device may be configured with the first configuration information. The two devices negotiate to determine the first configuration information. When the second device is a network device, the first device receives the first configuration information sent by the second device, the first configuration information is, for example, through a system information block (System Information Block, SIB) or radio resource control (Radio Resource Control, RRC) signaling bearer, the first configuration information may be resource pool configuration information or bandwidth segment (BandWidth Part, BWP) configuration information.

在一些实施例中，所述第一配置信息可以包括侧行链路符号长度(sl-LengthSymbols)参数，所述sl-LengthSymbols参数用于配置一个时隙内用于侧行链路的时域符号的数量。其中，用于侧行链路的时域符号的数量可以根据侧行带宽部分配置信息确定；侧行带宽部分配置信息例如是SL-BWP-Generic，该配置信息可以如下所示：In some embodiments, the first configuration information may include a sidelink symbol length (sl-LengthSymbols) parameter, where the sl-LengthSymbols parameter is used to configure time domain symbols used for the sidelink in one slot quantity. Wherein, the number of time domain symbols used for the sidelink can be determined according to the configuration information of the sidelink bandwidth part; the configuration information of the sidelink bandwidth part is, for example, SL-BWP-Generic, and the configuration information can be as follows:

其中，可根据侧行带宽部分配置信息中的“sl-LengthSymbols”确定用于侧行链路的时域符号的数量；用于侧行链路的时域符号数包括AGC符号以及GP符号。以图3所示的一个时隙内的时域符号的示意图为例，若sl-LengthSymbols参数的值为10，则表征用于侧行链路的时域符号的数量为10，10个时域符号包括全部的AGC符号和GP符号；一个时隙内可用于侧行传输的时域符号的起始符号位置由参数sl-StartSymbol-r16确定，图3中，sl-StartSymbol-r16参数的值设置为4，即表示第一个用于侧行传输的时域符号为图中的符号4。符号0至符号3不能用于传输侧行链路；符号5至符号9用于传输PSSCH。符号4为AGC时域符号，且符号4上传输的数据是符号5上传输的数据的重复；第10个时域符号和第13个时域符号为GP时域符号；符号11和符号12用于传输PSFCH，符号11上传输的数据与符号12上传输的数据相同，即符号11上传输的PSFCH是符号12上传输的PSFCH的重复，或符号12上传输的PSFCH是符号11上传输的PSFCH的重复；且符号11可以作为AGC时域符号。The number of time-domain symbols used for the sidelink can be determined according to "sl-LengthSymbols" in the configuration information of the sidelink bandwidth part; the number of time-domain symbols used for the sidelink includes AGC symbols and GP symbols. Taking the schematic diagram of the time-domain symbols in a time slot shown in FIG. 3 as an example, if the value of the sl-LengthSymbols parameter is 10, the number of time-domain symbols representing the sidelink is 10, and 10 time-domain symbols The symbols include all AGC symbols and GP symbols; the starting symbol position of the time domain symbols that can be used for sideline transmission in a time slot is determined by the parameter sl-StartSymbol-r16. In Figure 3, the value of the sl-StartSymbol-r16 parameter is set is 4, which means that the first time-domain symbol used for sideline transmission is symbol 4 in the figure. Symbols 0 to 3 cannot be used to transmit the sidelink; symbols 5 to 9 are used to transmit PSSCH. Symbol 4 is the AGC time domain symbol, and the data transmitted on symbol 4 is the repetition of the data transmitted on symbol 5; the 10th time domain symbol and the 13th time domain symbol are GP time domain symbols;

symbols

11 and 12 are used for For the transmission of the PSFCH, the data transmitted on symbol 11 is the same as the data transmitted on symbol 12, i.e. the PSFCH transmitted on symbol 11 is a repetition of the PSFCH transmitted on symbol 12, or the PSFCH transmitted on symbol 12 is the PSFCH transmitted on symbol 11 and the symbol 11 can be used as the AGC time domain symbol.

在另一些实施例中，所述第一配置信息还可以包括侧行链路PSFCH周期(sl-PSFCH-Period)参数，所述sl-PSFCH-Period参数用于配置PSFCH的传输周期；其中，PSFCH的传输周期可根据PSFCH的配置参数确定；PSFCH的配置参数可以如下所示：In other embodiments, the first configuration information may further include a sidelink PSFCH period (sl-PSFCH-Period) parameter, and the sl-PSFCH-Period parameter is used to configure the transmission period of the PSFCH; wherein the PSFCH The transmission period can be determined according to the configuration parameters of the PSFCH; the configuration parameters of the PSFCH can be as follows:

其中，可根据PSFCH的配置参数中的“sl-PSFCH-Period”确定PSFCH的传输周期。PSFCH的传输周期为N，N＝{0,1,2,4}个时隙，若N＝0，则表示该资源池不支持传输PSFCH。The transmission period of the PSFCH may be determined according to "sl-PSFCH-Period" in the configuration parameter of the PSFCH. The transmission period of the PSFCH is N, and N={0, 1, 2, 4} time slots. If N=0, it means that the resource pool does not support the transmission of the PSFCH.

在一些实施例中，若sl-LengthSymbols参数的值小于第一阈值，则配置sl-PSFCH-Period参数的值为0；即若sl-LengthSymbols参数的值小于10，则配置sl-PSFCH-Period参数的值为0。也可以理解为若sl-LengthSymbols参数的值小于10，如 sl-LengthSymbols参数的值为7、或8、或9，则不期望使能(enable)PSFCH，即第一设备不传输PSFCH。还可以理解为，若sl-LengthSymbols参数的值小于10，如sl-LengthSymbols参数的值为7、或8、或9，则该时隙内不支持传输PSFCH。相应的，若sl-LengthSymbols参数的值大于或等于第一阈值，则配置sl-PSFCH-Period参数的值N＝{0,1,2,4}个时隙；即若sl-LengthSymbols参数的值大于或等于10，则配置sl-PSFCH-Period参数的值N＝{0,1,2,4}个时隙。In some embodiments, if the value of the sl-LengthSymbols parameter is less than the first threshold, the value of the sl-PSFCH-Period parameter is configured as 0; that is, if the value of the sl-LengthSymbols parameter is less than 10, the sl-PSFCH-Period parameter is configured value of 0. It can also be understood that if the value of the sl-LengthSymbols parameter is less than 10, for example, the value of the sl-LengthSymbols parameter is 7, or 8, or 9, it is not expected to enable the PSFCH, that is, the first device does not transmit the PSFCH. It can also be understood that if the value of the sl-LengthSymbols parameter is less than 10, for example, the value of the sl-LengthSymbols parameter is 7, or 8, or 9, the transmission of the PSFCH is not supported in the time slot. Correspondingly, if the value of the sl-LengthSymbols parameter is greater than or equal to the first threshold, configure the value of the sl-PSFCH-Period parameter N={0, 1, 2, 4} time slots; that is, if the value of the sl-LengthSymbols parameter is If it is greater than or equal to 10, then configure the value N={0, 1, 2, 4} time slots of the sl-PSFCH-Period parameter.

在一些实施例中，用于侧行链路的时域符号包括AGC时域符号和/或GP时域符号。In some embodiments, the time domain symbols used for the sidelink include AGC time domain symbols and/or GP time domain symbols.

在一些实施例中，如果一个时隙中用于侧行传输的符号个数小于10，则第一设备不期望在该时隙中传输PSFCH。In some embodiments, if the number of symbols used for sideline transmission in a slot is less than 10, the first device does not expect to transmit the PSFCH in that slot.

在一些实施例中，如果一个时隙中用于侧行传输的符号个数小于10，则PSFCH的周期配置为0。In some embodiments, if the number of symbols used for sideline transmission in one slot is less than 10, the period of the PSFCH is configured to be 0.

在一些实施例中，传输PSFCH可以包括：发送所述PSFCH，和/或接收所述PSFCH。相应的，第一设备禁止传输PSFCH可以包括：第一设备不发送PSFCH，和/或第一设备不接收PSFCH。In some embodiments, transmitting the PSFCH may include transmitting the PSFCH, and/or receiving the PSFCH. Correspondingly, prohibiting the transmission of the PSFCH by the first device may include: the first device does not transmit the PSFCH, and/or the first device does not receive the PSFCH.

应理解，用于配置第一阈值、侧行链路符号长度参数和侧行链路PSFCH周期参数的配置信息可以是相同的配置信息，也可以是不同的配置信息。例如，通过第一RRC信令配置第一阈值，通过第二RRC信令配置侧行链路符号长度参数，通过第三RRC信令配置侧行链路PSFCH周期参数。或者，通过第一RRC信令配置第一阈值、侧行链路符号长度参数和侧行链路PSFCH周期参数。It should be understood that the configuration information for configuring the first threshold, the sidelink symbol length parameter and the sidelink PSFCH period parameter may be the same configuration information or different configuration information. For example, the first threshold is configured through the first RRC signaling, the sidelink symbol length parameter is configured through the second RRC signaling, and the sidelink PSFCH period parameter is configured through the third RRC signaling. Alternatively, the first threshold, the sidelink symbol length parameter and the sidelink PSFCH period parameter are configured through the first RRC signaling.

Repeat.

本申请图2和图4所示的实施例中，通过配置用于侧行链路的时域符号的数量小于第一阈值时，不传输PSFCH，即不支持传输侧行反馈传输信道，如此，能够合理、有效地分配一个时隙内的时域符号；使得在用于传输PSSCH的时域符号的数量小于6的情况下，仍可以使用相关技术中已有的DMRS图案，如使用图1-9和图1-10中的DMRS图案。In the embodiments shown in FIG. 2 and FIG. 4 of the present application, when the number of time domain symbols configured for the sidelink is smaller than the first threshold, the PSFCH is not transmitted, that is, the transmission of the sidelink feedback transmission channel is not supported. In this way, The time-domain symbols in a time slot can be allocated reasonably and effectively; so that when the number of time-domain symbols used for PSSCH transmission is less than 6, the existing DMRS patterns in the related art can still be used, such as using Figure 1- 9 and the DMRS pattern in Figures 1-10.

本申请实施例提供的信道配置方法的另一种可选处理流程示意图，如图5所示，至少可以包括：Another optional processing flow diagram of the channel configuration method provided by the embodiment of the present application, as shown in FIG. 5 , may at least include:

在一些实施例中，传输PSSCH的时域符号可以包括AGC时域符号。应理解，该AGC符号是可用于侧行传输的时域符号中的第一个符号，该符号上的数据是与该符号相邻的后一个符号上的数据的复制。In some embodiments, the time-domain symbols in which the PSSCH is transmitted may include AGC time-domain symbols. It should be understood that the AGC symbol is the first symbol in the time domain symbols available for sideline transmission, and the data on this symbol is a copy of the data on the next symbol adjacent to the symbol.

在一些实施例中，传输PSSCH的时域符号可以不包括GP时域符号。In some embodiments, the time-domain symbols in which the PSSCH is transmitted may not include GP time-domain symbols.

在一些实施例中，第一设备可以通过协议预定义的方式或预配置的方式获取第二配置信息，也可以由第二设备为第一设备配置第二配置信息，还可以是第一设备与第二设备协商确定第二配置信息。当所述第二设备是网络设备时，第一设备通过接收第二设备发送的第二配置信息，该第二配置信息例如是SIB或RRC信令承载，该第二配置信息可以是资源池配置信息或BWP配置信息。In some embodiments, the first device may acquire the second configuration information in a pre-defined manner or a pre-configured manner in a protocol, or the second device may configure the second configuration information for the first device, or the first device may be associated with The second device negotiates to determine the second configuration information. When the second device is a network device, the first device receives second configuration information sent by the second device, where the second configuration information is, for example, SIB or RRC signaling bearer, and the second configuration information may be a resource pool configuration information or BWP configuration information.

在一些实施例中，第二阈值为6。In some embodiments, the second threshold is six.

在一些实施例中，若第一设备确定所述时隙内用于传输PSSCH的时域符号的数量小于所述第二阈值，则所述第一设备禁止传输PSSCH。若所述时隙内用于传输PSSCH的时域符号的数量大于或等于所述第二阈值，则所述第一设备可以传输PSSCH。In some embodiments, if the first device determines that the number of time domain symbols used to transmit PSSCH in the time slot is less than the second threshold, the first device prohibits transmission of PSSCH. If the number of time-domain symbols used for PSSCH transmission in the time slot is greater than or equal to the second threshold, the first device may transmit the PSSCH.

在一些实施例中，针对第二阈值为6的情况，若第一设备确定一个时隙内用于传输PSSCH的时域符号的数量小于6，则所述第一设备不传输PSSCH。若第一设备确定一个时隙内用于传输PSSCH的时域符号的数量大于或等于6，则所述第一设备可以传输PSSCH。In some embodiments, for the case where the second threshold is 6, if the first device determines that the number of time-domain symbols used to transmit PSSCH in one time slot is less than 6, the first device does not transmit PSSCH. If the first device determines that the number of time-domain symbols used to transmit the PSSCH in one time slot is greater than or equal to 6, the first device may transmit the PSSCH.

在一些实施例中，第一设备不期望一个时隙内用于传输PSSCH的时域符号的数量小于所述第二阈值。In some embodiments, the first device does not expect that the number of time-domain symbols used to transmit PSSCH in a slot is less than the second threshold.

举例来说，若时隙中用于传输PSSCH的时域符号的数量等于第二阈值，即用于传输PSSCH的时域符号为6个，则该时隙内可以传输PSSCH。如果该时隙中包括用于传输PSFCH的时域符号，则时隙内用于侧行链路的总的时域符号数量可以为10个；即：时隙内包括6个用于传输PSSCH的时域符号、2个用于传输PSFCH的时域符号，以及2个GP时域符号。For example, if the number of time-domain symbols used for transmitting PSSCH in a time slot is equal to the second threshold, that is, the number of time-domain symbols used for transmitting PSSCH is 6, then PSSCH can be transmitted in this time slot. If the time slot includes time domain symbols used for transmitting PSFCH, the total number of time domain symbols used for sidelink in the time slot may be 10; that is, the time slot includes 6 time domain symbols used for transmitting PSSCH Time domain symbols, 2 time domain symbols for transmitting PSFCH, and 2 GP time domain symbols.

再举例来说，若时隙中用于传输PSSCH的时域符号的数量大于第二阈值，如用于传输PSSCH的时域符号为7个，则该时隙内可以传输PSSCH。如果该时隙中包括用于传输PSFCH的时域符号，则时隙内用于侧行链路的总的时域符号数量可以为11个；即：时隙内包括7个用于传输PSSCH的时域符号、2个用于传输PSFCH的时域符号，以及2个GP时域符号。For another example, if the number of time-domain symbols used for PSSCH transmission in the time slot is greater than the second threshold, for example, the number of time-domain symbols used for PSSCH transmission is 7, the PSSCH can be transmitted in the time slot. If the time slot includes time domain symbols used for transmitting PSFCH, the total number of time domain symbols used for the sidelink in the time slot may be 11; that is, the time slot includes 7 time domain symbols used for transmitting PSSCH Time domain symbols, 2 time domain symbols for transmitting PSFCH, and 2 GP time domain symbols.

在一些实施例中，第二设备可以向第一设备发送第二配置信息，第一设备可以根据第二配置信息确定在时隙内是否传输PSSCH。当所述第二设备是网络设备时，第一设备通过接收第二设备发送的第二配置信息，该第二配置信息例如是SIB或RRC信令承载，该第二配置信息可以是资源池配置信息或BWP配置信息。In some embodiments, the second device may send second configuration information to the first device, and the first device may determine whether to transmit the PSSCH in the time slot according to the second configuration information.
