Description

侧行链路通信方法和装置Sidelink communication method and device
本申请要求于2022年9月30日提交中国专利局、申请号为202211214342.4、申请名称为“侧行链路通信方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。This application claims priority to the Chinese patent application filed with the China Patent Office on September 30, 2022, with application number 202211214342.4 and application name “Sidelink Communication Method and Device”, the entire contents of which are incorporated by reference in this application.
技术领域Technical Field
本申请涉及通信领域，更具体地，涉及一种侧行链路通信方法和装置。The present application relates to the field of communications, and more specifically, to a sidelink communication method and device.
背景技术Background technique
在新空口(New Radio，NR)侧行链路***中，终端设备可以在资源池中与其他终端设备进行通信，资源池中会周期性配置物理侧行反馈信道(physical sidelink feedback channel，PSFCH)反馈资源，用于传输数据的物理侧行控制信道(physical sidelink control channel，PSCCH)资源与周期性配置的PSFCH反馈资源有对应的映射关系。按照标准Rel-18协议，基于长期演进的车联网技术(Long Term Evolution-vehicle，LTE-V)和基于新空口的车联网技术(New Radio-vehicle，NR-V)共信道共存时，使用专用载波来传输NR-V中的PSFCH。In the New Radio (NR) sidelink system, terminal devices can communicate with other terminal devices in the resource pool, and the resource pool will periodically configure the physical sidelink feedback channel (PSFCH) feedback resources. The physical sidelink control channel (PSCCH) resources used to transmit data have a corresponding mapping relationship with the periodically configured PSFCH feedback resources. According to the standard Rel-18 protocol, when the Long Term Evolution-vehicle (LTE-V) and New Radio-vehicle (NR-V) co-exist on the same channel, a dedicated carrier is used to transmit the PSFCH in NR-V.
然而，共信道共存的一个目的是为了利用LTE-V传输的频谱，由于LTE-V的逐步退网，LTE-V传输的用户数和需要占用的频谱资源均有所下降，通过共享LTE-V传输的频谱可以使能NR-V的传输，且能起到提高频谱利用效率的效果。另一方面，专用于PSFCH传输的频谱是否存在，以及如何寻找这样一个时频资源集合尚不明确。因此，如何保证NR-V和LTE-V在不影响LTE-V性能的前提下实现共信道传输的动态共存，成为亟待解决的问题。However, one purpose of co-channel coexistence is to utilize the spectrum of LTE-V transmission. Due to the gradual withdrawal of LTE-V from the network, the number of users of LTE-V transmission and the spectrum resources required have decreased. Sharing the spectrum of LTE-V transmission can enable the transmission of NR-V and improve the efficiency of spectrum utilization. On the other hand, it is not clear whether there is a spectrum dedicated to PSFCH transmission and how to find such a set of time-frequency resources. Therefore, how to ensure the dynamic coexistence of NR-V and LTE-V in co-channel transmission without affecting the performance of LTE-V has become an urgent problem to be solved.
发明内容Summary of the invention
本申请提供一种侧行链路通信方法和装置，能够保证NR-V和LTE-V可以在不影响LTE-V性能的前提下实现共信道传输的动态共存。The present application provides a sidelink communication method and device, which can ensure that NR-V and LTE-V can achieve dynamic coexistence of co-channel transmission without affecting LTE-V performance.

It should be understood that in this case, the first indication information can be PSSCH, or the second-level SCI in PSSCH, or the corresponding field in the second-level SCI in PSSCH.

应理解，该第一资源集合为共享资源的集合，即NR-V和LTE-V共享的资源集合(即用于LTE-V的传输，也用于NR-V的传输)。或者理解为LTE-V的资源集合(且该资源集合与NR-V共享)，也可以理解为LTE-V资源集合和NE-V资源集合重叠的部分。It should be understood that the first resource set is a set of shared resources, that is, a resource set shared by NR-V and LTE-V (that is, used for LTE-V transmission and also for NR-V transmission). Or it can be understood as a resource set of LTE-V (and the resource set is shared with NR-V), or it can be understood as the overlapping part of the LTE-V resource set and the NE-V resource set.

结合第一方面，在第一方面的某些实现方式中，该第一资源为LTE-V传输占用的资源，且该第一资源对应的能量测量值大于第一阈值。通过在确定第一资源的过程中考虑能量测量值，该第一终端能够利用LTE-V能量测量值较低的资源，提高资源利用效率，且不影响LTE-V的传输。In combination with the first aspect, in some implementations of the first aspect, the first resource is a resource occupied by LTE-V transmission, and the energy measurement value corresponding to the first resource is greater than a first threshold. By considering the energy measurement value in the process of determining the first resource, the first terminal can use resources with lower LTE-V energy measurement values to improve resource utilization efficiency without affecting LTE-V transmission.
结合第一方面，在第一方面的某些实现方式中，该NR-V数据对应的反馈信息承载于PSFCH中，PSFCH资源被周期性的配置在共享资源池中。该共享资源池可以理解为该第一资源集合。In conjunction with the first aspect, in some implementations of the first aspect, the feedback information corresponding to the NR-V data is carried in the PSFCH, and the PSFCH resources are periodically configured in a shared resource pool.

为了便于理解本申请实施例，首先，对实施例涉及的概念及技术作简单介绍。In order to facilitate understanding of the embodiments of the present application, first, a brief introduction is given to the concepts and technologies involved in the embodiments.
资源：resource:
具体而言，是指时频资源。按照标准Rel-16/Rel-17NR协议，物理侧行控制信道PSCCH(physical sidelink control channel，PSCCH)或物理侧行共享信道(physical sidelink shared channel，PSSCH)的调度粒度在时域上单位为一个时隙，频域上单位为连续一个或者多个个子信道。发送终端装置可以在该资源上发送侧行信息，在一个资源上可以承载PSCCH、PSSCH、物理侧行反馈信道(physical sidelink feedback channel，PSFCH)三种信道和解调参考信号(demodulation reference signal，DM-RS)、信道状态信息参考信号(channel state information reference signal，CSI-RS)等信号。PSCCH中承载第一级侧行控制信息(sidelink control information，SCI)，PSSCH中承载第二级SCI和/或数据，PSFCH承载反馈信息。其中PSCCH/PSSCH包括PSCCH和/或PSSCH。Specifically, it refers to time-frequency resources. According to the standard Rel-16/Rel-17NR protocol, the scheduling granularity of the physical sidelink control channel PSCCH (physical sidelink control channel, PSCCH) or the physical sidelink shared channel (physical sidelink shared channel, PSSCH) is a time slot in the time domain and one or more continuous sub-channels in the frequency domain. The transmitting terminal device can send sidelink information on this resource. Three channels, including PSCCH, PSSCH, and physical sidelink feedback channel (physical sidelink feedback channel, PSFCH), and demodulation reference signal (demodulation reference signal, DM-RS), channel state information reference signal (channel state information reference signal, CSI-RS) and other signals can be carried on one resource. PSCCH carries the first-level sidelink control information (sidelink control information, SCI), PSSCH carries the second-level SCI and/or data, and PSFCH carries feedback information. PSCCH/PSSCH includes PSCCH and/or PSSCH.
资源池：Resource Pool:
资源池是时频资源的集合。具体而言，资源池是指侧行链路中UE用于传输PSSCH或接收PSSCH的时频资源的集合。资源池包含的频域资源是连续的。资源池包含的时域资源可以是连续的，也可以是不连续的。UE可以被配置一个或者多个资源池，应理解，本申请实施例中LTE V传输与NR V传输能够使用相同的资源池。A resource pool is a collection of time-frequency resources. Specifically, a resource pool refers to a collection of time-frequency resources used by a UE in a sidelink to transmit or receive PSSCH. The frequency domain resources contained in the resource pool are continuous. The time domain resources contained in the resource pool may be continuous or discontinuous. A UE may be configured with one or more resource pools, and it should be understood that LTE V transmission and NR V transmission in the embodiment of the present application can use the same resource pool.
HARQ技术HARQ Technology
在无线通信***，在收发双方，通常采用混合自动重传请求(hybrid automatic repeat request，HARQ)技术来保证数据传输的正确性。HARQ技术将前向纠错(forward error correction，FEC)与自动重传请求(automatic repeat request，ARQ)结合起来，数据块(一般称为一个传输块(transport block，TB))编码后，第一次传输时发送信息比特和一部分冗余比特。若接收端能够正确译码则反馈确认(acknowledgement，ACK)信号给发送端，发送端接收到ACK信号后确认接收端已经成功接收到相应的信息比特，认为该数据块已经成功传输。若接收端不能正确译码，则接收端向发送端反馈否认(negative acknowledgement，NACK)信号给发送端，发送端接收到NACK信号后再进一步传输一部分信息比特和/或冗余比特(称为重传数据)给接收端，接收端接收到重传数据后，与之前接收到的数据合并后进行译码，若加上重传数据仍然无法正确译码，则可以进行再次重传。随着重传次数的增加，信息比特和/或冗余比特不断积累，信道编码率不断降低，从而可以不断提升译码效果。In wireless communication systems, hybrid automatic repeat request (HARQ) technology is usually used by both the sender and the receiver to ensure the correctness of data transmission. HARQ technology combines forward error correction (FEC) with automatic repeat request (ARQ). After the data block (generally called a transport block (TB)) is encoded, the information bits and some redundant bits are sent during the first transmission. If the receiving end can decode correctly, it will feedback an acknowledgment (ACK) signal to the sending end. After receiving the ACK signal, the sending end confirms that the receiving end has successfully received the corresponding information bits and believes that the data block has been successfully transmitted. If the receiving end cannot decode correctly, the receiving end will feedback a negative acknowledgment (NACK) signal to the sending end. After receiving the NACK signal, the sending end will further transmit a part of the information bits and/or redundant bits (called retransmission data) to the receiving end. After receiving the retransmission data, the receiving end will combine it with the previously received data for decoding. If the retransmission data still cannot be decoded correctly, it can be retransmitted again. As the number of retransmissions increases, the information bits and/or redundant bits continue to accumulate, and the channel coding rate continues to decrease, thereby continuously improving the decoding effect.
NR V2X中单播传输和组播传输支持HARQ反馈，单播的接收端为一个，单播即一对UE之间进行通信，组播的接收端为有限数量个，即发送UE发送组播数据，有限数量的组内UE接收数据。Unicast transmission and multicast transmission in NR V2X support HARQ feedback. There is only one receiving end for unicast, that is, communication between a pair of UEs. There is a limited number of receiving ends for multicast, that is, the sending UE sends multicast data, and a limited number of UEs in the group receive the data.
HARQ信息承载于物理侧行反馈信道PSFCH中。The HARQ information is carried in the physical sidelink feedback channel PSFCH.
单播支持ACK或NACK的反馈方式，即接收UE成功接收数据则反馈ACK，没有成功接收数据则反馈NACK。Unicast supports ACK or NACK feedback mode, that is, the receiving UE feeds back ACK if it successfully receives the data, and feeds back NACK if it fails to successfully receive the data.
物理侧行控制信道(PSCCH)：Physical Sidelink Control Channel (PSCCH):
PSCCH承载一阶SCI。为了便于描述，在不做区分时，PSCCH和SCI表示含义相同。在时域上，PSCCH占用从第二个侧行符号开始的两个或三个正交频分复用(orthogonal freq,OFDM)符号；在频域上，承载PSCCH的物理资源块(physical resource blocks,PRB)从关联的PSSCH的最低子信道的最低PRB开始，且PSCCH占据的PRB个数在一个PSSCH的子带范围内。PSCCH由{10,12,15,20,25}个资源块(resource block,RB)组成，具体取值由无线资源控制(reference signal received power,RRC)信令指示或者预配置。PSCCH carries the first-order SCI. For ease of description, PSCCH and SCI have the same meaning when no distinction is made. In the time domain, PSCCH occupies two or three orthogonal frequency division multiplexing (orthogonal freq, OFDM) symbols starting from the second sideline symbol; in the frequency domain, the physical resource blocks (physical resource blocks, PRB) carrying PSCCH start from the lowest PRB of the lowest subchannel of the associated PSSCH, and the number of PRBs occupied by PSCCH is within the subband range of a PSSCH. PSCCH consists of {10,12,15,20,25} resource blocks (resource blocks, RB), and the specific value is indicated by the radio resource control (reference signal received power, RRC) signaling or pre-configured.
物理侧行共享信道(PSSCH):Physical Sidelink Shared Channel (PSSCH):
PSSCH承载二阶SCI、媒体接入控制-控制元素(medium access control-control element，MAC CE) 和数据中的至少2种。SCI可以指一阶SCI和/或二阶SCI。为了便于描述，在不做区分时，SCI指一阶SCI、二阶SCI、一阶和二阶SCI中的任意一种。时域上，在没有PSFCH的资源上，有12个符号用于承载PSSCH；在有PSFCH的资源上，有9个符号用于承载PSSCH。频域上，占据连续LsubCh个子信道。另外，在一个时隙内，第一个OFDM符号复制第二个符号上发送的信息，用于自动增益控制(automatic gain control，AGC)。PSSCH carries the second-order SCI and medium access control-control element (MAC CE) and data. SCI may refer to first-order SCI and/or second-order SCI. For ease of description, when no distinction is made, SCI refers to any one of first-order SCI, second-order SCI, first-order and second-order SCI. In the time domain, on resources without PSFCH, there are 12 symbols used to carry PSSCH; on resources with PSFCH, there are 9 symbols used to carry PSSCH. In the frequency domain, it occupies consecutive LsubCh subchannels. In addition, within a time slot, the first OFDM symbol copies the information sent on the second symbol for automatic gain control (AGC).
物理侧行反馈信道(PSFCH):Physical Sidelink Feedback Channel (PSFCH):
PSFCH资源表示用于传输PSFCH的资源。作为示例，一个PSFCH在时域上占用2个连续的正交频分复用(orthogonal frequency division multiplexing，OFDM符号)，频域为1个物理资源块(physical resource block，PRB)。在有PSFCH的资源上，倒数第二个和第三个OFDM符号承载PSFCH。倒数第三个符号上的信号是倒数第二个符号上信号的重复，以便接收终端装置进行AGC调整。PSFCH resources represent resources used to transmit PSFCH. As an example, one PSFCH occupies 2 consecutive orthogonal frequency division multiplexing (OFDM symbols) in the time domain and 1 physical resource block (PRB) in the frequency domain. On resources with PSFCH, the penultimate and third OFDM symbols carry PSFCH. The signal on the penultimate symbol is a repetition of the signal on the penultimate symbol so that the receiving terminal device can perform AGC adjustment.
作为一种可能的情形，PSFCH可用于传输反馈信息。举例来说，针对一次PSSCH传输，若发送端在控制信息中携带混合自动重传请求确认(hybrid automatic repeat request acknowledgment，HARQ-ACK)反馈使能信息，则接收端可根据此次PSSCH的译码结果反馈相应的肯定(acknowledgement，ACK)或否定(negative acknowledgement，NACK)信息。其中ACK或NACK信息通过PSFCH传输。As a possible scenario, PSFCH can be used to transmit feedback information. For example, for a PSSCH transmission, if the transmitter carries the hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback enable information in the control information, the receiver can feedback the corresponding positive (ACK) or negative (NACK) information based on the decoding result of the PSSCH. The ACK or NACK information is transmitted through the PSFCH.
GAP符号:GAP Symbol:
终端装置可能在连续两个时隙分别接收和发送PSSCH，或者终端装置可能在同一个时隙分别接收和发送PSSCH和PSFCH。因此，在PSSCH后和PSFCH符号之后，均需要额外增加一个符号用于终端装置的收发转换。The terminal device may receive and send PSSCH in two consecutive time slots, or may receive and send PSSCH and PSFCH in the same time slot. Therefore, an additional symbol is required after the PSSCH and PSFCH symbols for the terminal device to switch between sending and receiving.
AGC符号:AGC Symbol:
该符号位于传输的起始符号，例如PSCCH/PSSCH传输的符号#0，例如PSFCH传输的符号#11。由于不能一边进行AGC调整一边接收、译码数据。因此AGC符号上的信号是下一个符号上信号内容的复制。由于SL传输保持每个符号上的功率相等，因此可以基于AGC符号的自动增益控制的结果接收剩余符号的内容。This symbol is located at the start symbol of the transmission, such as symbol #0 for PSCCH/PSSCH transmission, such as symbol #11 for PSFCH transmission. Since it is not possible to receive and decode data while performing AGC adjustment, the signal on the AGC symbol is a copy of the signal content on the next symbol. Since SL transmission maintains equal power on each symbol, the content of the remaining symbols can be received based on the result of automatic gain control of the AGC symbol.
确定PSFCH资源Determine PSFCH resources
(1)PSFCH资源的配置周期(1) PSFCH resource configuration cycle
PSFCH资源可以是配置在资源池中的周期性资源。举例来说，假设周期参数为N_PSSCH^PSFCH，作为示例，N_PSSCH^PSFCH的取值可以是0、1、2、4。若N_PSSCH^PSFCH＝0，则表示该资源池中无PSFCH资源，也即该资源池内的资源不可用于传输PSFCH。若N_PSSCH^PSFCH≠0，则表示该资源池中，在一个时间窗内每N_PSSCH^PSFCH个时隙会有一个PSFCH资源。PSFCH resources can be periodic resources configured in a resource pool. For example, assuming that the periodic parameter is N_PSSCH^PSFCH, as an example, the value of N_PSSCH^PSFCH can be 0, 1, 2, or 4. If N_PSSCH^PSFCH=0, it means that there are no PSFCH resources in the resource pool, that is, the resources in the resource pool cannot be used to transmit PSFCH. If N_PSSCH^PSFCH≠0, it means that in the resource pool, there will be one PSFCH resource for every N_PSSCH^PSFCH time slots in a time window.
图1是PSFCH资源的一个示意图。PSFCH资源是周期性的配置在资源池上的，PSFCH资源的配置周期是N个时隙，当N＝4时，资源池中，每4个时隙中有一个时隙包含PSFCH资源。其中，PSFCH占用符号为1个，称为PSFCH符号。PSFCH符号的前一个符号为AGC符号，即PSFCH符号的前一个符号为PSFCH符号的复制，PSFCH符号的前一个符号和PSFCH符号承载的内容是相同。PSFCH符号的前一个符号的前一个符号为GP符号，即PSFCH符号向前第二个符号为GP符号。该符号的作用是两个传输之间的收发转换。比如UE在符号1-9接收数据，在符号11-12发送PSFCH，UE需要收发转换的时间。Figure 1 is a schematic diagram of PSFCH resources. PSFCH resources are periodically configured in the resource pool. The configuration period of PSFCH resources is N time slots. When N=4, in the resource pool, one time slot in every 4 time slots contains PSFCH resources. Among them, PSFCH occupies 1 symbol, called PSFCH symbol. The previous symbol of the PSFCH symbol is the AGC symbol, that is, the previous symbol of the PSFCH symbol is a copy of the PSFCH symbol, and the content carried by the previous symbol of the PSFCH symbol and the PSFCH symbol is the same. The previous symbol of the previous symbol of the PSFCH symbol is the GP symbol, that is, the second symbol from the PSFCH symbol to the front is the GP symbol. The role of this symbol is to convert the transmission and reception between two transmissions. For example, the UE receives data in symbols 1-9 and sends PSFCH in symbols 11-12. The UE needs time for transmission and reception conversion.
(2)确定PSFCH资源的时域资源(2) Determine the time domain resources of PSFCH resources
对于NR-V2X，HARQ反馈的定时即PSSCH到PSFCH之间的时间间隔。假设一个PSSCH传输的结束位置在时隙n，相应的进行HARQ反馈的时隙为在包括n+k时隙在内以及n+k时隙后的第一个存在PSFCH资源的时隙，PSFCH资源又可以被称为PSFCH传输机会。其中，k体现终端的处理能力，例如，k可以为2或3等。For NR-V2X, the timing of HARQ feedback is the time interval between PSSCH and PSFCH. Assuming that the end position of a PSSCH transmission is in time slot n, the corresponding time slot for HARQ feedback is the first time slot with PSFCH resources including and after time slot n+k. PSFCH resources can also be called PSFCH transmission opportunities. Among them, k reflects the processing capability of the terminal. For example, k can be 2 or 3, etc.
(3)确定PSFCH资源的频域资源和码域资源(3) Determine the frequency domain resources and code domain resources of PSFCH resources
在一个配置的资源池内，PSFCH的频域和码域资源是使用隐式关联的规则确定的。一个PSFCH反馈时隙内的PSFCH可用资源按照先时域后频域的方式，顺序分配给反馈周期内的每个子信道。In a configured resource pool, the frequency domain and code domain resources of PSFCH are determined using implicit association rules. The available PSFCH resources in a PSFCH feedback slot are allocated to each subchannel in the feedback cycle in a sequential manner, first in the time domain and then in the frequency domain.
图2示出了PSSCH资源与PSFCH资源映射关系的一个示例。假设如图2中的(a)所示，PSFCH资源配置的周期参数为2(即每2个时隙中有一个时隙包含PSFCH资源)，反馈定时k＝2(PSSCH到 PSFCH的最小时间间隔)，与包含PSFCH资源的时隙3对应的PSSCH时隙个数为2。子信道的个数为3，每个子信道包含10个PRB，可用于传输HARQ信息的PRB为30个，配置用于传输HARQ信息的PRB个数为12。这样，每个子信道可以对应2个物理资源块(physical resource block，PRB)，例如，子信道(0，0)对应于子信道索引为0和时隙索引为0，该子信道对应于PRB索引为0、1、2的反馈资源。每个RB还对应码域资源，包括CS(Cyclic Shift，循环移位)对。CS的对数和序列的长度有关。序列长度为12，则CS对数最大为6。FIG2 shows an example of the mapping relationship between PSSCH resources and PSFCH resources. Assume that as shown in FIG2 (a), the period parameter of PSFCH resource configuration is 2 (i.e., one time slot in every two time slots contains PSFCH resources), and the feedback timing k = 2 (PSSCH to The minimum time interval of PSFCH), the number of PSSCH time slots corresponding to time slot 3 containing PSFCH resources is 2. The number of subchannels is 3, each subchannel contains 10 PRBs, 30 PRBs can be used to transmit HARQ information, and the number of PRBs configured for transmitting HARQ information is 12. In this way, each subchannel can correspond to 2 physical resource blocks (PRBs). For example, subchannel (0, 0) corresponds to a subchannel index of 0 and a time slot index of 0, and the subchannel corresponds to feedback resources with PRB indices of 0, 1, and 2. Each RB also corresponds to code domain resources, including CS (Cyclic Shift) pairs. The logarithm of CS is related to the length of the sequence. If the sequence length is 12, the maximum number of CS logarithms is 6.
如图2中的(b)所示，CS对N_"CS"^"PSFCH"的配置为3对，则子信道(0,0)对应的频域和码域资源如上图所示，即一个子信道对应了6个可用于传输HARQ的资源(资源的粒度频域双是一个PRB，码域是一个CS对)。As shown in (b) of Figure 2, the configuration of CS pairs N_"CS"^"PSFCH" is 3 pairs, then the frequency domain and code domain resources corresponding to the subchannel (0,0) are as shown in the above figure, that is, one subchannel corresponds to 6 resources that can be used to transmit HARQ (the granularity of the resource in the frequency domain is one PRB, and the code domain is one CS pair).
SCI所指示的资源：Resources indicated by SCI:
NR-V中，UE使用mode2的资源选择方式选择资源，UE用第一级SCI指示时频资源。第一级SCI最多指示2个资源或3个资源。这个由网络设备配置在资源池上，或者预配置在资源池上。SCI指示的第一个资源即SCI调度使用的资源。SCI指示的第二个资源，第三个资源是预留的资源，即UE在SCI指示时还没使用的资源。In NR-V, the UE uses the resource selection method of mode 2 to select resources. The UE uses the first-level SCI to indicate the time-frequency resources. The first-level SCI indicates at most 2 resources or 3 resources. This is configured on the resource pool by the network device, or pre-configured on the resource pool. The first resource indicated by the SCI is the resource used by the SCI scheduling. The second resource indicated by the SCI and the third resource are reserved resources, that is, the resources that the UE has not used when the SCI indicates.
第一级SCI中指示资源的字段包含两个：The first-level SCI contains two fields indicating resources:
频域资源分配字段，当SCI所指示的资源的最大数量为2时，该字段占用的比特数(最大9比特(L＝27))；当SCI所指示的资源的最大数量为3时，该字段占用的比特数为(最大13比特(L＝27))。Frequency domain resource allocation field. When the maximum number of resources indicated by SCI is 2, the number of bits occupied by this field is (maximum 9 bits (L=27)); when the maximum number of resources indicated by SCI is 3, the number of bits occupied by this field is (maximum 13 bits (L=27)).
时域资源分配字段，当SCI所指示的资源的最大数量为2时，该字段占用的比特数为5bits，当SCI所指示的资源的最大数量为3时，该字段占用的比特数为9bits。Time domain resource allocation field: when the maximum number of resources indicated by the SCI is 2, the number of bits occupied by this field is 5 bits; when the maximum number of resources indicated by the SCI is 3, the number of bits occupied by this field is 9 bits.
如下所述(SCI所指示的资源的最大数量为3)，UE要指示3个资源，R1-0和R1-1和R1-2。则需要指示他们所在时隙，频域起始位置和长度。频域资源分配字段的作用是指示资源的起始位置和频域长度。且SCI所指示的资源的频域长度是相同的。As described below (the maximum number of resources indicated by SCI is 3), the UE needs to indicate 3 resources, R1-0, R1-1 and R1-2. It is necessary to indicate their time slots, frequency domain starting positions and lengths. The frequency domain resource allocation field is used to indicate the starting position and frequency domain length of the resources. And the frequency domain lengths of the resources indicated by SCI are the same.
时域资源分配字段的作用是指示当SCI所指示的资源的最大数量为2时，实际的1或2个资源的逻辑时间间隔，当SCI所指示的资源的最大数量为3时，实际的1或2或3个资源的逻辑时间间隔。The function of the time domain resource allocation field is to indicate the actual logical time interval of 1 or 2 resources when the maximum number of resources indicated by the SCI is 2, and the actual logical time interval of 1, 2 or 3 resources when the maximum number of resources indicated by the SCI is 3.
N是SCI实际所指示的资源的个数，时间间隔的确定过程如下：N is the number of resources actually indicated by the SCI. The time interval is determined as follows:
如果N＝1，TRIV＝0If N=1, TRIV=0
否则如果N＝2，TRIV＝t1Otherwise if N＝2, TRIV＝t1
否则otherwise
如果(t2-t1-1)≤15，TRIV＝30(t2-t1-1)+t1+31If (t2-t1-1)≤15, TRIV＝30(t2-t1-1)+t1+31
否则，TRIV＝30(31-t2+t1)+62-t1Otherwise, TRIV = 30(31-t2+t1)+62-t1

如图3所示，其中第一个资源所在时隙是接收SCI的时隙。ti表示资源池内相较于第一个资源的以逻辑时隙为单位的时间间隔(时域偏移值)。N＝2，1≤t1≤31，N＝3，1≤t1≤30，t1<t2≤31。As shown in Fig. 3, the time slot where the first resource is located is the time slot for receiving SCI. ti represents the time interval (time domain offset value) in the resource pool compared with the first resource in the logical time slot. N=2, 1≤t 1 ≤31, N=3, 1≤t 1 ≤30, t 1 <t 2 ≤31.
如图3所示，假设UEA发送了SCI，SCI所指示的资源包含已使用资源R1-0和预留资源R1-1，R1-2；其中频域资源分配字段指示的是第二个资源R1-1的频域起始位置和第三个资源R1-2的频域起始位置以及三个资源的频域长度，第一个资源R1-0的频域起始位置n1-0不需要指示，因为其他UE检测到SCI的时候，可以根据SCI所在的子信道推断出第一个资源的频域起始位置因此不需要额外指示，如图5所示，PSCCH和PSSCH的复用结构图如下。As shown in Figure 3, assuming that UEA sends SCI, the resources indicated by SCI include used resources R1-0 and reserved resources R1-1, R1-2; the frequency domain resource allocation field indicates the frequency domain starting position of the second resource R1-1 and the frequency domain starting position of the third resource R1-2 and the frequency domain length of the three resources. The frequency domain starting position n1-0 of the first resource R1-0 does not need to be indicated, because when other UEs detect SCI, they can infer the frequency domain starting position of the first resource based on the sub-channel where the SCI is located, so no additional indication is required. As shown in Figure 5, the multiplexing structure diagram of PSCCH and PSSCH is as follows.
如图4所示，假设UEA发送了SCI，SCI所指示的资源包含已使用资源R1-0和预留资源R1-1，R1-2；R2-0，R2-1，R2-2。其中，R2-0，R2-1，R2-2是根据R1-0和预留资源R1-1，R1-2和周期确定的。比如资源R1-0和资源R2-0的时间间隔是周期P；资源R1-1和资源R2-1的时间间隔是周期P；资源R1-2和资源R2-2的时间间隔是周期P；周期P是根据SCI中的资源预留周期字段确定的，占用的比特数为Nrsv_period是高层配置的周期取值的集合。As shown in Figure 4, assuming that the UEA sends SCI, the resources indicated by the SCI include the used resource R1-0 and the reserved resources R1-1, R1-2; R2-0, R2-1, R2-2. Among them, R2-0, R2-1, R2-2 are determined based on R1-0 and the reserved resources R1-1, R1-2 and the period. For example, the time interval between resource R1-0 and resource R2-0 is period P; the time interval between resource R1-1 and resource R2-1 is period P; the time interval between resource R1-2 and resource R2-2 is period P; period P is determined based on the resource reservation period field in the SCI, and the number of bits occupied is N rsv_period is a set of period values configured by the higher layer.
其他UE根据检测到SCI中的TRIV，FRIV和资源预留周期字段，可以推断出第一个周期所指示 的资源，和后面的周期内所指示的资源。Other UEs can infer the first cycle indicated by detecting the TRIV, FRIV and resource reservation cycle fields in the SCI. resources, and the resources indicated in the subsequent cycles.
具体的，关于FRIV字段的确定方式如下：Specifically, the FRIV field is determined as follows:
当SCI所指示的资源的最大数量为2， When the maximum number of resources indicated by SCI is 2,
当SCI所指示的资源的最大数量为3， When the maximum number of resources indicated by SCI is 3,
其中，表示第二个资源的起始子信道索引，表示第三个资源的起始子信道索引，是资源池的子信道个数，这个是基站配置或预配置的。如果TRIV所指示的N<sl-MaxNumPerReserve(SCI所指示的资源的最大数量),sl-MaxNumPerReserve–N的剩余起始子信道索引不被使用。in, Indicates the starting subchannel index of the second resource, Indicates the starting subchannel index of the third resource, The number of subchannels in the resource pool, which is configured or pre-configured by the base station.

随着无线通信技术的发展，人们对周边人或事物与其通信的邻近服务的需求逐渐增加，因此设备到设备(device to device，D2D)技术应运而生。D2D技术的应用，可以减轻蜂窝网络的负担、减少用户设备的电池功耗、提高数据传输速率，并能很好地满足用户的邻近服务的需求。D2D技术允许多个支持D2D功能的用户设备在有网络基础设施或无网络基础设施的情况下进行直接发现和直接通信。鉴于D2D技术的特点和优势，基于D2D技术的车联网应用场景被提出，但是因涉及安全性的考虑，这种场景下对时延的要求非常高，现有的D2D技术无法满足其安全性的要求。With the development of wireless communication technology, people's demand for proximity services for communicating with people or things around them has gradually increased, so device-to-device (D2D) technology has emerged. The application of D2D technology can reduce the burden on cellular networks, reduce the battery power consumption of user devices, increase data transmission rates, and well meet the needs of users for proximity services. D2D technology allows multiple user devices that support D2D functions to conduct direct discovery and direct communication with or without network infrastructure. In view of the characteristics and advantages of D2D technology, the application scenario of the Internet of Vehicles based on D2D technology has been proposed, but due to security considerations, the latency requirements in this scenario are very high, and the existing D2D technology cannot meet its security requirements.
因此在第三代合作伙伴计划(the 3rd generation partnership project，3GPP)提出的LTE技术的网络下，车与任何事物通信(vehicle to everything，V2X)的车联网技术被提出，V2X通信是指车辆与外界的任何事物的通信，包括车与车的通信(vehicle to vehicle，V2V)、车与行人的通信(vehicle to pedestrian，V2P)、车与基础设施的通信(vehicle to infrastructure，V2I)、车与网络的通信(vehicle to network，V2N)。Therefore, under the network of LTE technology proposed by the 3rd generation partnership project (3GPP), vehicle to everything (V2X) vehicle networking technology was proposed. V2X communication refers to the communication between a vehicle and anything outside, including vehicle to vehicle (V2V), vehicle to pedestrian (V2P), vehicle to infrastructure (V2I), and vehicle to network (V2N).
V2X通信针对以车辆为代表的高速设备，是未来对通信时延要求非常高的场景下应用的基础技术和关键技术，如智能汽车、自动驾驶、智能交通运输***等场景。V2X通信可以支持有网络覆盖和无网络覆盖的通信场景，其资源分配方式可以采取网络接入设备调度模式，如演进通用陆地无线接入网节点B(E-UTRAN Node B，简称为eNB)调度模式和终端装置自选模式。基于V2X技术，车辆用户(Vehicle终端装置，简称为V-终端装置)能将自身的一些信息，例如位置、速度、意图(转弯、并线、倒车)等信息周期性以及一些非周期性的事件触发的信息向周围的V-终端装置发送，同样地V-终端装置也会实时接收周围用户的信息。V2X communication is aimed at high-speed equipment represented by vehicles. It is the basic technology and key technology for applications in scenarios with very high communication latency requirements in the future, such as smart cars, autonomous driving, and intelligent transportation systems. V2X communication can support communication scenarios with and without network coverage, and its resource allocation method can adopt network access equipment scheduling mode, such as Evolved Universal Terrestrial Radio Access Network Node B (E-UTRAN Node B, referred to as eNB) scheduling mode and terminal device self-selection mode. Based on V2X technology, vehicle users (Vehicle terminal devices, referred to as V-terminal devices) can send some of their own information, such as location, speed, intention (turning, merging, reversing), etc., periodically and some non-periodic event-triggered information to the surrounding V-terminal devices. Similarly, the V-terminal devices will also receive information from surrounding users in real time.
图5的(a)和(b)是适用于本申请实施例的通信场景示意图。本申请实施例提供的信息传输的方法可应用于终端直连通信(侧行链路通信)、车联网、蜂窝通信(包括5G NR通信，LTE)，以及WiFi通信***中，如侧行链路通信中的终端设备。终端装置可以在无网络覆盖时，通过sidelink通信。终端装置也可以位于网络装置的覆盖范围内，覆盖范围内的终端装置也可以和覆盖范围外的终端装置进行直连通信(sidelink通信)。以V2X场景为例，车载终端需要与网络保持连接，以获得一些配置信息，也需要与其他车载终端保持连接，以实现车载通信。车载终端设备与基站之间的连接为上行链路和下行链路，车载终端设备之间的连接为侧行链路。(a) and (b) of Figure 5 are schematic diagrams of communication scenarios applicable to embodiments of the present application. The information transmission method provided in the embodiments of the present application can be applied to terminal direct communication (sidelink communication), Internet of Vehicles, cellular communication (including 5G NR communication, LTE), and WiFi communication systems, such as terminal devices in sidelink communication. The terminal device can communicate via sidelink when there is no network coverage. The terminal device can also be located within the coverage area of the network device, and the terminal device within the coverage area can also communicate directly (sidelink communication) with the terminal device outside the coverage area. Taking the V2X scenario as an example, the vehicle-mounted terminal needs to maintain a connection with the network to obtain some configuration information, and also needs to maintain a connection with other vehicle-mounted terminals to achieve vehicle-mounted communication. The connection between the vehicle-mounted terminal device and the base station is an uplink and a downlink, and the connection between the vehicle-mounted terminal devices is a sidelink.
应理解，本申请实施例也可以应用于其它的通信***，并且对通信***中包括的网络设备和终端设备的数量不做限定。只要该通信***中存在实体可以发送信息，该通信***也存在其它实体可以接收信息即可。 It should be understood that the embodiments of the present application can also be applied to other communication systems, and the number of network devices and terminal devices included in the communication system is not limited. As long as there is an entity in the communication system that can send information, there are other entities in the communication system that can receive information.
此外，在本申请实施例的通信场景中，网络设备用于为终端设备提供通信服务并接入核心网，终端设备可以通过搜索网络设备发送的同步信号、广播信号等信号接入网络，从而建立与网络设备之间的通信。In addition, in the communication scenario of the embodiment of the present application, the network device is used to provide communication services for the terminal device and access the core network. The terminal device can access the network by searching for synchronization signals, broadcast signals and other signals sent by the network device, thereby establishing communication with the network device.
应理解，在本申请实施例使用的通信场景中，LTE-V传输和NR-V传输的共信道共存是十分常见的，即LTE-V传输和NR-V传输能够使用的时频资源集合是相同的。因此，为了避免LTE-V传输和NR-V传输发生冲突，NR-V传输时需要考虑根据考虑到LTE-V传输的位置，不和LTE-V传输的位置发生冲突。It should be understood that in the communication scenario used in the embodiment of the present application, the co-channel coexistence of LTE-V transmission and NR-V transmission is very common, that is, the time-frequency resource set that can be used by LTE-V transmission and NR-V transmission is the same. Therefore, in order to avoid conflicts between LTE-V transmission and NR-V transmission, NR-V transmission needs to consider the location of LTE-V transmission and not conflict with the location of LTE-V transmission.
下文通过LTE-V帧结构和NR-V帧结构，对LTE-V传输和NR-V传输发生冲突的原因进行详细说明。The following article explains in detail the reasons why LTE-V transmission and NR-V transmission conflict through the LTE-V frame structure and the NR-V frame structure.
首先，需要说明的是，对于同样的时频资源，LTE-V和NR-V对于帧结构的理解是有区别的。LTE-V的传输一个子帧占用14个符号，调度数据的时域单元为一个子帧。NR-V的传输一个时隙占用14个符号，调度数据的时域单元为一个时隙。First of all, it should be noted that for the same time-frequency resources, LTE-V and NR-V have different understandings of the frame structure. LTE-V transmission occupies 14 symbols in one subframe, and the time domain unit for scheduling data is one subframe. NR-V transmission occupies 14 symbols in one time slot, and the time domain unit for scheduling data is one time slot.
作为示例而非限定，如图6所示，在LTE-V中，一个子帧中的第一个符号用于自动增益控制符号，即符号#0为AGC符号。在NR-V中，当一个时隙中包括PSFCH资源时，时隙的符号#0’(PSSCH的第一个符号的前一个符号)和符号#11’(PSFCH符号的前一个符号)用于AGC调整。这是因为使用符号#1’-#9’传输数据的UE和使用符号12传输PSFCH的UE不一定是同一个，并且符号#11’中用于传输PSFCH的UE可能不止一个，同时符号#1’-#9’中传输PSSCH的功率和符号#12’中传输PSFCH的功率是不同的，因此在传输PSFCH前需要采用AGC符号进行功率调整。As an example and not a limitation, as shown in FIG6 , in LTE-V, the first symbol in a subframe is used for an automatic gain control symbol, that is, symbol #0 is an AGC symbol. In NR-V, when a time slot includes a PSFCH resource, symbol #0’ (the symbol before the first symbol of the PSSCH) and symbol #11’ (the symbol before the PSFCH symbol) of the time slot are used for AGC adjustment. This is because the UE that uses symbols #1’-#9’ to transmit data and the UE that uses symbol 12 to transmit PSFCH are not necessarily the same, and there may be more than one UE used to transmit PSFCH in symbol #11’, and the power of transmitting PSSCH in symbols #1’-#9’ and the power of transmitting PSFCH in symbol #12’ are different, so AGC symbols are required for power adjustment before transmitting PSFCH.
容易理解的是，当LTE-V传输和PSFCH符号重叠时，LTE-V模块在符号#0调整功率后，由于受到NR-V传输中符号#12’处的PSFCH干扰，从而影响自身符号#11-#12的功率调整，导致LTE-V的接收性能变差。It is easy to understand that when LTE-V transmission and PSFCH symbols overlap, after the LTE-V module adjusts the power at symbol #0, it is interfered by the PSFCH at symbol #12' in the NR-V transmission, which affects the power adjustment of its own symbols #11-#12, resulting in poor reception performance of LTE-V.
本申请实施例提供了一种侧行链路通信方法和装置，用户设备能够判定NR-V数据对应的反馈信息对应的资源与用于LTE-V传输在时域上是否重叠，并根据判定结果控制用户设备的NR-V传输，从而避免NR PSFCH传输和LTE-V传输在时域上重叠时，发送NR-V传输反馈信息影响LTE-V传输的接收性能的问题。The embodiments of the present application provide a side link communication method and apparatus, and a user equipment can determine whether the resources corresponding to the feedback information corresponding to the NR-V data overlap with those used for LTE-V transmission in the time domain, and control the NR-V transmission of the user equipment according to the determination result, thereby avoiding the problem that when the NR PSFCH transmission and the LTE-V transmission overlap in the time domain, the sending of the NR-V transmission feedback information affects the receiving performance of the LTE-V transmission.

It is not limited here that a certain resource in the shared resource pool is used by the NR wireless access system and the LTE wireless access system at the same time, and the coexistence mode of the NR wireless access system and the LTE wireless access system in the resource pool is not limited.

As an example but not limitation, the NR-V module of terminal #A can receive indication information sent by the LTE-V module of the same terminal, thereby obtaining the time-frequency position of resource #A. This can be understood as the interaction or transparent transmission between the NR-V module and the LTE-V module.
应理解，终端#A还能够通过其他方式获取指示信息#1，作为示例而非限定，终端#A的NR-V模块获取另一终端的LTE-V模块发送的指示信息，从而获取资源#A的时频位置。It should be understood that terminal #A can also obtain indication information #1 in other ways. As an example but not limitation, the NR-V module of terminal #A obtains the indication information sent by the LTE-V module of another terminal, thereby obtaining the time-frequency position of resource #A.
在一种可能的实现方式中，资源#A为LTE-V传输占用的资源，且资源#A∈资源集合#A1。即终端#A获取的是资源集合#A1(可以理解为指示信息#1指示的是资源集合#A1)。其中，资源集合#A1是资源集合#1的子集(或者资源集合#A1和资源池#1有重叠)，且资源集合#A1中的资源为LTE-V传输占用的资源，资源#A可以是资源集合#A1中的一个资源，也可以是资源集合#A1中的多个资源，本申请对此不作限定。资源集合#A1在时域上占用一个时间窗，应理解，时间窗可以为时域单元的集合，时隙的集合，子帧的集合，本申请实施例在此不作限定。资源集合#A1在频域上的范围为LTE-V的资源池或者共享资源池的范围。In one possible implementation, resource #A is a resource occupied by LTE-V transmission, and resource #A∈resource set #A1. That is, terminal #A obtains resource set #A1 (it can be understood that indication information #1 indicates resource set #A1). Among them, resource set #A1 is a subset of resource set #1 (or resource set #A1 and resource pool #1 overlap), and the resources in resource set #A1 are resources occupied by LTE-V transmission. Resource #A can be one resource in resource set #A1 or multiple resources in resource set #A1, and this application does not limit this. Resource set #A1 occupies a time window in the time domain. It should be understood that the time window can be a set of time domain units, a set of time slots, or a set of subframes, and this embodiment of the application does not limit this. The range of resource set #A1 in the frequency domain is the range of the LTE-V resource pool or shared resource pool.
作为示例而非限定，指示信息#1指示资源集合#A1中的资源#A的时域位置和频域位置，从而使终端#A能够通过指示信息#1确定LTE-V传输占用的资源的时频位置。终端#A能够同时确定多组时频资源，每组时频资源指示的资源个数为3个。其中，组内3个资源的第一个资源的频域起始位置，第一个资源的时域位置单独指示。此外，第二个资源和第三个资源的起始位置，时域位置，以及三个资源的频域长度使用时域资源指示值(Time resource indication value，TRIV)，时域资源指示值(Frequency resource indication value，FRIV)指示。As an example and not a limitation, indication information #1 indicates the time domain position and frequency domain position of resource #A in resource set #A1, so that terminal #A can determine the time and frequency position of the resources occupied by LTE-V transmission through indication information #1. Terminal #A can simultaneously determine multiple groups of time and frequency resources, and the number of resources indicated by each group of time and frequency resources is 3. Among them, the frequency domain starting position of the first resource of the three resources in the group and the time domain position of the first resource are indicated separately. In addition, the starting position, time domain position of the second and third resources, and the frequency domain length of the three resources are indicated using the time domain resource indication value (TRIV) and the time domain resource indication value (FRIV).
应理解，为判定(确定)LTE-V占用的资源与资源#B在时域上是否重叠，本申请实施例的指示信息#1也可仅指示资源集合#A1中的资源#A的时域位置，本申请实施例对此不作限定。It should be understood that in order to determine (confirm) whether the resources occupied by LTE-V overlap with resource #B in the time domain, the indication information #1 of the embodiment of the present application may also only indicate the time domain position of resource #A in resource set #A1, and the embodiment of the present application is not limited to this.
作为示例而非限定，指示信息#1指示时域参考点，从而使终端#A能够通过指示信息#1确定LTE-V传输占用的资源的时频位置。对于每组时频资源的时频位置，组内第一个资源的时域位置根据时域参考点和slot offset确定。应理解，时域参考点为第一组时频资源的第一个资源的时域位置，则第一组时频资源不需要slot offset。如图8所示，以两组LTE-V资源的指示方式为例。第一组资源由{TRIV 1，FRIV 1}和资源1的频域起始位置指示，第二组资源由{TRIV 2，FRIV 2}、slot offset2以及资源4的频域起始位置指示。As an example and not a limitation, indication information #1 indicates a time domain reference point, so that terminal #A can determine the time-frequency position of the resources occupied by LTE-V transmission through indication information #1. For the time-frequency position of each group of time-frequency resources, the time domain position of the first resource in the group is determined according to the time domain reference point and slot offset. It should be understood that if the time domain reference point is the time domain position of the first resource of the first group of time-frequency resources, then the first group of time-frequency resources does not require slot offset. As shown in Figure 8, take the indication method of two groups of LTE-V resources as an example. The first group of resources is indicated by {TRIV 1, FRIV 1} and the frequency domain starting position of resource 1, and the second group of resources is indicated by {TRIV 2, FRIV 2}, slot offset 2, and the frequency domain starting position of resource 4.
作为示例而非限定，指示信息#1指示资源集合#A1的频域范围。因而终端#A可以确定NR-V和LTE-V所共享的资源的频域范围。As an example but not limitation, indication information #1 indicates the frequency domain range of resource set #A1. Thus, terminal #A can determine the frequency domain range of resources shared by NR-V and LTE-V.
作为示例而非限定，指示信息#1指示SCI的解码结果，终端#A接收资源#A的时频资源的指示信息，从而确定LTE-V传输占用的资源的时频位置。具体而言，终端#A的NR-V模块根据LTE-V传输的SCI的解码结果即可确定资源集合#A1中资源#A的时频资源的位置。As an example but not a limitation, indication information #1 indicates the decoding result of SCI, and terminal #A receives the indication information of the time-frequency resources of resource #A, thereby determining the time-frequency position of the resources occupied by LTE-V transmission. Specifically, the NR-V module of terminal #A can determine the position of the time-frequency resources of resource #A in resource set #A1 based on the decoding result of SCI transmitted by LTE-V.
在另一种可能的实现方式中，资源#A为LTE-V传输占用的资源，且资源#A属于资源集合#A2。即终端#A获取的是资源集合#A2(可以理解为指示信息#1指示的是资源集合#A2)。其中，资源集合#A2是资源集合#1的子集(或者资源集合#A2和资源池#1有重叠)，资源集合#A2中的资源均为LTE-V传输占用且相应的能量测量值大于阈值#A(第一阈值的一例)的资源，资源#A可以是资源集合#A2中的一个资源，也可以是资源集合#A2中的多个资源，本申请对此不作限定。资源集合#A2在时域和频域上的范围与资源集合#A1相同，此处不再赘述。In another possible implementation, resource #A is a resource occupied by LTE-V transmission, and resource #A belongs to resource set #A2. That is, terminal #A obtains resource set #A2 (it can be understood that indication information #1 indicates resource set #A2). Among them, resource set #A2 is a subset of resource set #1 (or resource set #A2 and resource pool #1 overlap), and the resources in resource set #A2 are all occupied by LTE-V transmission and the corresponding energy measurement value is greater than threshold #A (an example of the first threshold). Resource #A can be one resource in resource set #A2 or multiple resources in resource set #A2, and this application does not limit this. The range of resource set #A2 in the time domain and frequency domain is the same as that of resource set #A1, which will not be repeated here.
作为示例而非限定，能量测量值为RSRP测量值，即资源集合#A2中的资源是LTE-V模块检测到的LTE-V的传输占用且相应的参考信号接收功率(Reference Signal Receiving Power，RSRP)测量值大于阈值#A的资源。As an example but not limitation, the energy measurement value is an RSRP measurement value, that is, the resources in resource set #A2 are the resources detected by the LTE-V module as being occupied by LTE-V transmission and whose corresponding reference signal receiving power (RSRP) measurement value is greater than the threshold #A.
作为示例而非限定，终端#A能够通过获取指示信息#1确定LTE-V传输占用的资源的时频信息和能量测量值。具体而言，终端#A的NR-V模块获取指示信息#1，指示信息#1指示SCI的解码结果和SCI关联的RSSP测量值。终端#A通过指示信息确定LTE-V传输占用的资源的时频位置。其中，该相应的DMRS RSRP可以是根据检测到的SCI调度的PSSCH的DMRS测量的，或者是根据检测到的SCI所在PSCCH的DMRS测量的。这里该LTE-V的传输占用的资源为该SCI指示的资源。其中，LTE-V中，SCI也可以理解或替换为SA。SCI为承载于PSCCH中的控制信息。这里对其名称不做具体限定。 As an example but not a limitation, terminal #A can determine the time-frequency information and energy measurement value of the resources occupied by LTE-V transmission by obtaining indication information #1. Specifically, the NR-V module of terminal #A obtains indication information #1, and indication information #1 indicates the decoding result of SCI and the RSSP measurement value associated with SCI. Terminal #A determines the time-frequency position of the resources occupied by LTE-V transmission through the indication information. Among them, the corresponding DMRS RSRP can be measured according to the DMRS of the PSSCH scheduled by the detected SCI, or according to the DMRS of the PSCCH where the detected SCI is located. Here, the resources occupied by the LTE-V transmission are the resources indicated by the SCI. Among them, in LTE-V, SCI can also be understood or replaced by SA. SCI is control information carried in PSCCH. Its name is not specifically limited here.
应理解，阈值#A根据优先级#A(第一优先级的一例)和优先级#B(第二优先级的一例)确定。其中，优先级#A是LTE-V资源选择或重选时使用的优先级(优先级值)，优先级#B是SCI中指示的优先级(优先级值)。应理解，优先级可以是LTE-V传输中的优先级(ProSe Per-Packet Priority，PPPP)，或者，NR-V传输中的优先级，本申请实施例对此不作限定。应理解，RSRP测量值的阈值#A也可以由其他方式确定。例如，阈值#A来自RSRP阈值表格，阈值#A根据两个优先级值在RSRP阈值表格中确定。如表1所示，该RSRP阈值表格为两维表格，其中一个维度是sensing的优先级，即进行资源选择或资源重选时使用的优先级，另一个维度是检测的SCI中的优先级。本申请对此不作限定。PPPP的取值范围为整数1到8，包括8个值，其中值越小表示优先级别越高，即越重要。优先级值的取值范围为整数1到8，包括8个值，其中值越小表示优先级别越高，即越重要。It should be understood that the threshold #A is determined according to the priority #A (an example of the first priority) and the priority #B (an example of the second priority). Among them, the priority #A is the priority (priority value) used in LTE-V resource selection or reselection, and the priority #B is the priority (priority value) indicated in the SCI. It should be understood that the priority can be the priority (ProSe Per-Packet Priority, PPPP) in LTE-V transmission, or the priority in NR-V transmission, and the embodiment of the present application is not limited to this. It should be understood that the threshold #A of the RSRP measurement value can also be determined by other means. For example, the threshold #A comes from the RSRP threshold table, and the threshold #A is determined in the RSRP threshold table according to two priority values. As shown in Table 1, the RSRP threshold table is a two-dimensional table, one dimension of which is the priority of sensing, that is, the priority used when performing resource selection or resource reselection, and the other dimension is the priority in the detected SCI. This application is not limited to this. The value range of PPPP is an integer from 1 to 8, including 8 values, where the smaller the value, the higher the priority level, that is, the more important it is. The priority value ranges from 1 to 8, including 8 values, where a smaller value indicates a higher priority, ie, more important.

应理解，能量测量值也可为其他测量值。作为示例而非限定，能量测量值为接收信号强度指示(received signal strength indicator，RSSI)测量值、信道质量指示(Channel Quality Indication，CQI)测量值、信号干扰噪声比(Signal To Interference Plus Noise Ratio,SINR)测量值或信号噪声功率比(Signal To Nosie Ratio，SNR)测量值中的一种。作为示例而非限定，对于以上能量测量值中的一种，阈值#A是配置的。即阈值#A可以预配置或者由网络设备配置，或者为预设的取值。It should be understood that the energy measurement value may also be other measurement values. As an example and not limitation, the energy measurement value is a received signal strength indicator (RSSI) measurement value, a channel quality indication (CQI) measurement value, a signal to interference and noise ratio (SINR) measurement value, or a signal to noise power ratio (SNR) measurement value. As an example and not limitation, for one of the above energy measurement values, the threshold #A is configured. That is, the threshold #A can be pre-configured or configured by the network device, or it can be a preset value.
作为示例而非限定，终端#A能够通过获取指示信息#1确定LTE-V传输占用的资源的时频信息和相应的能量测量值(也可以理解为LTE-V传输占用的资源和相应的能量测量值)。具体而言，终端#A的NR-V模块获取指示信息#1，指示信息#1指示LTE-V传输占用的资源以及LTE-V模块检测到的上述能量测量值中的一种。相应的能量测量值为根据LTE-V传输占用的资源内进行测量所确定的能量测量值。As an example but not limitation, terminal #A can determine the time-frequency information and corresponding energy measurement values of the resources occupied by LTE-V transmission by obtaining indication information #1 (which can also be understood as the resources occupied by LTE-V transmission and the corresponding energy measurement values). Specifically, the NR-V module of terminal #A obtains indication information #1, and indication information #1 indicates the resources occupied by LTE-V transmission and one of the above energy measurement values detected by the LTE-V module. The corresponding energy measurement value is an energy measurement value determined by measuring within the resources occupied by LTE-V transmission.
在另一种可能的实现方式中，资源#A为用于LTE-V传输的候选资源，资源#A属于资源集合#A3。其中，资源集合#A3是资源集合#1的子集(或者资源集合#A3和资源集合#1有重叠)，且资源集合#A3中的资源为可用于LTE-V传输的候选资源。如图9所示，资源集合#A3是LTE-V模块在资源选择或重选的过程中，在资源集合#2(第二资源集合的一例)中排除了与LTE-V传输占用的资源重叠的候选资源后，剩余的候选资源的集合。其中，资源集合#2是资源选择窗内的所有能够用于LTE-V传输的候选资源。该资源选择窗为一个时间窗，或者一个时间段，或者一个子帧集合，或者一个时隙集合。该资源选择窗为LTE-V模块确定的或者由NR-V模块向LTE-V模块指示的。资源#A可以是资源集合#A3中的一个资源，也可以是资源集合#A3中的多个资源，本申请对此不作限定。In another possible implementation, resource #A is a candidate resource for LTE-V transmission, and resource #A belongs to resource set #A3. Among them, resource set #A3 is a subset of resource set #1 (or resource set #A3 and resource set #1 overlap), and the resources in resource set #A3 are candidate resources that can be used for LTE-V transmission. As shown in Figure 9, resource set #A3 is a set of candidate resources remaining after the LTE-V module excludes candidate resources overlapping with the resources occupied by LTE-V transmission in resource set #2 (an example of the second resource set) during resource selection or reselection. Among them, resource set #2 is all candidate resources that can be used for LTE-V transmission in the resource selection window. The resource selection window is a time window, or a time period, or a subframe set, or a time slot set. The resource selection window is determined by the LTE-V module or indicated by the NR-V module to the LTE-V module. Resource #A can be a resource in resource set #A3, or it can be multiple resources in resource set #A3, and this application does not limit this.
需要说明的是，用于LTE-V传输的候选资源在时域上占用一个子帧，在频域上占用一个或多个子信道。可选的，用于LTE-V传输的候选资源为多个时，每个候选资源在频域上占用的子信道的个数相同。应理解，用于LTE-V传输的候选资源可以理解为单个子帧候选资源或者单个候选资源或者候选子帧资源。It should be noted that the candidate resources for LTE-V transmission occupy one subframe in the time domain and one or more subchannels in the frequency domain. Optionally, when there are multiple candidate resources for LTE-V transmission, each candidate resource occupies the same number of subchannels in the frequency domain. It should be understood that the candidate resources for LTE-V transmission can be understood as a single subframe candidate resource or a single candidate resource or a candidate subframe resource.
应理解，终端#A能够根据指示信息#1确定用于LTE-V传输的候选资源，该用于LTE-V传输的候选资源可以为一个或多个。具体而言，指示信息#1指示资源集合#A3的方式可以与指示资源集合#A1的方式相同，也可以通过其他方式指示资源集合#A3中资源#A。作为示例而非限定，指示信息#1指示 资源集合#A3的时域范围(时域起始位置和时域结束位置，或者时域起始位置和长度)和/或频域范围。其中，确定资源#A时参照的时域参考点可以是预设的，例如，发送前述指示信息的时间相较于DFN＝0或SFN＝0的时域参考点。It should be understood that terminal #A can determine candidate resources for LTE-V transmission according to indication information #1, and the candidate resources for LTE-V transmission can be one or more. Specifically, the method in which indication information #1 indicates resource set #A3 can be the same as the method in which resource set #A1 is indicated, or resource #A in resource set #A3 can be indicated in other ways. As an example and not a limitation, indication information #1 indicates The time domain range (time domain starting position and time domain ending position, or time domain starting position and length) and/or frequency domain range of resource set #A3. The time domain reference point referenced when determining resource #A may be preset, for example, the time of sending the aforementioned indication information is compared to the time domain reference point of DFN=0 or SFN=0.
在另一种可能的实现方式中，资源#A为用于LTE-V传输的候选资源且相应的能量测量值小于或等于阈值#B(第一阈值的另一例)的资源，且资源#A属于资源集合#A4(第二资源集合的另一例)，其中，资源集合#A4是资源集合#1的子集。在资源集合#2(第二资源集合的一例)中排除了与LTE-V传输占用的资源有重叠且相应的能量测量值大于阈值#B的候选资源后，剩余的候选资源的集合。其中，资源集合#2是资源选择窗内的所有用于LTE-V的候选资源。资源#A可以是资源集合#A4中的一个资源，也可以是资源集合#A1中的多个资源，本申请对此不作限定。In another possible implementation, resource #A is a candidate resource for LTE-V transmission and the corresponding energy measurement value is less than or equal to threshold #B (another example of the first threshold), and resource #A belongs to resource set #A4 (another example of the second resource set), wherein resource set #A4 is a subset of resource set #1. The set of remaining candidate resources after excluding candidate resources that overlap with resources occupied by LTE-V transmission and whose corresponding energy measurement values are greater than threshold #B in resource set #2 (an example of the second resource set). Among them, resource set #2 is all candidate resources for LTE-V within the resource selection window. Resource #A can be a resource in resource set #A4 or multiple resources in resource set #A1, and this application does not limit this.
作为示例而非限定，资源集合#A4可以为LTE-V资源选择或重选过程中执行完步骤6后的SA，即排除了与LTE-V传输占用的资源有重叠且相应RSRP测量值大于阈值#B的候选资源后，剩余候选资源的集合。As an example but not limitation, resource set #A4 can be the SA after executing step 6 in the LTE-V resource selection or reselection process, that is, the set of remaining candidate resources after excluding candidate resources that overlap with resources occupied by LTE-V transmission and whose corresponding RSRP measurement values are greater than threshold #B.
作为示例而非限定，资源集合#A4可以为LTE-V的资源选择或重选过程中，执行完步骤7后的SA，即排除了与LTE-V传输占用的资源有重叠且相应的能量测量值大于阈值#B的候选资源后，且SA中的资源个数不小于资源选择窗(Resource Selection window，RSW)中候选资源总数量的20％的剩余候选资源的集合。As an example but not limitation, resource set #A4 can be the SA after executing step 7 in the resource selection or reselection process of LTE-V, that is, after excluding candidate resources that overlap with resources occupied by LTE-V transmission and whose corresponding energy measurement values are greater than threshold #B, and the number of resources in SA is not less than 20% of the total number of candidate resources in the resource selection window (RSW).
作为示例而非限定，资源集合#A4可以为LTE-V的资源选择或重选过程中，执行完步骤9后的SB，即排除了与LTE-V传输占用的资源有重叠且相应的RSRP测量值大于阈值#B的候选资源后，SA中的资源个数不小于RSW中候选资源总数量的20％且优先选择了的RSSI测量值较小的剩余候选资源的集合。As an example but not limitation, resource set #A4 can be the SB after executing step 9 during the resource selection or reselection process of LTE-V, that is, after excluding candidate resources that overlap with resources occupied by LTE-V transmission and whose corresponding RSRP measurement values are greater than threshold #B, the number of resources in SA is not less than 20% of the total number of candidate resources in RSW, and the remaining candidate resources with smaller RSSI measurement values are preferentially selected.
应理解，指示信息#1指示资源集合#A4中的资源#A的方式与指示资源集合#A3中的资源#A的时频位置的方式相同，此处不再赘述。It should be understood that the manner in which indication information #1 indicates resource #A in resource set #A4 is the same as the manner in which indication information #1 indicates the time-frequency position of resource #A in resource set #A3, and thus will not be repeated here.
需要说明的是，终端#A在RP上被(预)配置上述4种资源集合(资源集合#A1，资源集合#A2，资源集合#A3，资源集合#4)或者4种资源集合的任何一个子集中的一种。应理解，终端#A还能够在资源池上接收来自网络设备的信息，该信息指示终端#A配置为上述4种资源集合或者4种资源集合的任何一个子集中的一种，本申请在此不做限定。It should be noted that terminal #A is (pre) configured with one of the above four resource sets (resource set #A1, resource set #A2, resource set #A3, resource set #4) or any subset of the four resource sets on the RP. It should be understood that terminal #A can also receive information from a network device on the resource pool, which indicates that terminal #A is configured as one of the above four resource sets or any subset of the four resource sets, and this application does not limit this.
容易理解的是，为确定LTE-V传输占用的资源是否与资源#B重叠，终端#A还需获取与NR-V数据对应的反馈信息的资源#B。具体而言，终端#A能够通过接收到NR-V数据所使用的资源#C(第三资源的一例)确定反馈信息对应的资源#B，即根据使用NR传输的数据所使用的资源确定使用NR传输的反馈信息所使用的资源，其中，资源#B与资源#C隐式相关，本申请实施例不对此作具体说明。It is easy to understand that in order to determine whether the resources occupied by LTE-V transmission overlap with resource #B, terminal #A also needs to obtain resource #B of the feedback information corresponding to the NR-V data. Specifically, terminal #A can determine the resource #B corresponding to the feedback information by receiving resource #C (an example of the third resource) used by the NR-V data, that is, determine the resources used for the feedback information transmitted using NR according to the resources used for the data transmitted using NR, wherein resource #B is implicitly related to resource #C, which is not specifically described in the embodiments of the present application.
应理解，资源#B为PSFCH符号中的一个PRB。PSFCH符号为一个时隙中的倒数第二个符号。终端#A使用资源#B发送NR-V的反馈信息，NR-V的反馈信息承载于PSFCH。It should be understood that resource #B is a PRB in a PSFCH symbol. A PSFCH symbol is the second to last symbol in a time slot. Terminal #A uses resource #B to send NR-V feedback information, and the NR-V feedback information is carried on the PSFCH.
应理解，终端#A是接收数据，发送反馈信息的设备。作为示例而非限定，终端#A在时隙1接收数据，在时隙2反馈PSFCH，其中时隙2是NR-V资源池内，N个时间间隔后的第一个包括PSFCH资源的时隙。其中，NR-V资源池可以理解为资源集合#1，即共享资源池。也可以理解为NR-V资源池包括资源集合#1，即NR-V资源池里包括共信道共存的共享资源和专用于NR-V的资源。It should be understood that terminal #A is a device that receives data and sends feedback information. As an example and not a limitation, terminal #A receives data in time slot 1 and feeds back PSFCH in time slot 2, where time slot 2 is the first time slot in the NR-V resource pool that includes PSFCH resources after N time intervals. Among them, the NR-V resource pool can be understood as resource set #1, that is, a shared resource pool. It can also be understood that the NR-V resource pool includes resource set #1, that is, the NR-V resource pool includes shared resources for co-channel coexistence and resources dedicated to NR-V.
作为示例而非限定，资源#B属于资源集合#B1，资源集合#B1是资源集合#1的子集，在NR-V传输和LTE-V传输的共信道传输中，资源集合#B1是NR-V的资源池和LTE-V资源池的重叠部分。其中，NR-V资源池可包括的内容不同，示例性的，NR-V的资源池包括NR-V专用的资源，即包括和LTE-V共享的资源和包括专用于NR-V的资源。示例性的，NR-V的资源池仅包括和LTE-V共享的资源，即NR-V的可用的资源集合也是LTE-V的可用的资源集合，本申请在此不作限定。As an example but not limitation, resource #B belongs to resource set #B1, resource set #B1 is a subset of resource set #1, and in the co-channel transmission of NR-V transmission and LTE-V transmission, resource set #B1 is the overlapping part of the NR-V resource pool and the LTE-V resource pool. Among them, the NR-V resource pool may include different contents. Exemplarily, the NR-V resource pool includes NR-V-specific resources, that is, resources shared with LTE-V and resources dedicated to NR-V. Exemplarily, the NR-V resource pool only includes resources shared with LTE-V, that is, the available resource set of NR-V is also the available resource set of LTE-V, and this application is not limited here.
NR-V传输发送的数据需要HARQ反馈，即使用NR无线接入***发送的数据需要HARQ反馈。具体而言，终端#A接收SCI，SCI调度PSSCH，PSSCH中承载数据信息。第二级SCI中的HARQ使能字段指示HARQ使能(即HARQ使能/去使能字段指示为1,1表示HARQ使能，0表示HARQ去使能)。第二级SCI中的cast type字段指示传输类型为单播或组播。The data sent by NR-V transmission requires HARQ feedback, that is, the data sent using the NR wireless access system requires HARQ feedback. Specifically, terminal #A receives SCI, SCI schedules PSSCH, and PSSCH carries data information. The HARQ enable field in the second-level SCI indicates HARQ enablement (that is, the HARQ enable/disable field indicates 1, 1 means HARQ enablement, and 0 means HARQ disablement). The cast type field in the second-level SCI indicates whether the transmission type is unicast or multicast.
需要说明的是，LTE-V的子载波间隔为15kHz，NR-V的子载波间隔可以为15kHz，30kHz，60kHz。当NR-V的子载波间隔为15kHz时，LTE-V的子帧长度和NR-V的时隙长度相同。 It should be noted that the subcarrier spacing of LTE-V is 15kHz, and the subcarrier spacing of NR-V can be 15kHz, 30kHz, and 60kHz. When the subcarrier spacing of NR-V is 15kHz, the subframe length of LTE-V is the same as the time slot length of NR-V.
如图10所示，当NR-V的子载波间隔为30kHz或60kHz时，LTE-V的子帧长度和NR-V的时隙长度不同。作为示例而非限定，NR-V模块获取的LTE-V模块的资源信息的时域单元以NR-V模块的时域单元为准，NR-V模块获取的LTE-V的资源的时域单元为子帧，则NR-V模块根据LTE-V的子载波间隔和LTE-V的资源的时域单元转换为NR-V的时域单元，进而可以利用LTE-V的资源指示信息。应理解，NR-V模块获取的LTE-V模块的资源信息的时域单元也能够以LTE-V模块的时域单元为准，本申请对此不作限定。As shown in Figure 10, when the subcarrier spacing of NR-V is 30kHz or 60kHz, the subframe length of LTE-V is different from the time slot length of NR-V. As an example and not a limitation, the time domain unit of the resource information of the LTE-V module obtained by the NR-V module is based on the time domain unit of the NR-V module, and the time domain unit of the LTE-V resources obtained by the NR-V module is a subframe. The NR-V module converts the subcarrier spacing of LTE-V and the time domain unit of LTE-V resources into the time domain unit of NR-V, and then the resource indication information of LTE-V can be used. It should be understood that the time domain unit of the resource information of the LTE-V module obtained by the NR-V module can also be based on the time domain unit of the LTE-V module, and this application is not limited to this.
S120，终端#A根据指示信息#1，确定LTE-V传输占用的资源和资源#B是否重叠。S120, terminal #A determines whether the resources occupied by LTE-V transmission overlap with resources #B based on indication information #1.
在一种可能的实现方式中，终端#A根据指示信息#1确定LTE-V传输占用的资源是否与资源#B重叠，终端#A通过用于LTE-V传输的候选资源的资源#A，进而确定LTE-V传输占用的资源是否与资源#B重叠。具体而言，对于资源集合#A3或者资源集合#A4的资源#A，终端#A确定资源集合#A3或者资源集合#A4中的资源#A是否与资源#B重叠，从而确定LTE-V传输占用的资源是否与资源#B重叠。In a possible implementation, terminal #A determines whether the resources occupied by LTE-V transmission overlap with resource #B according to indication information #1, and terminal #A determines whether the resources occupied by LTE-V transmission overlap with resource #B through resource #A of candidate resources for LTE-V transmission. Specifically, for resource #A of resource set #A3 or resource set #A4, terminal #A determines whether resource #A in resource set #A3 or resource set #A4 overlaps with resource #B, thereby determining whether the resources occupied by LTE-V transmission overlap with resource #B.
作为示例而非限定，终端#A通过用于LTE-V传输的候选资源的资源集合#A3和/或资源集合#A3中的资源#A，确定资源#A和资源#B是否满足条件#A，从而确定LTE-V传输占用的资源是否与资源#B重叠。As an example but not limitation, terminal #A determines whether resource #A and resource #B satisfy condition #A through resource set #A3 of candidate resources for LTE-V transmission and/or resource #A in resource set #A3, thereby determining whether the resources occupied by LTE-V transmission overlap with resource #B.
具体而言，条件#A包括如下子条件：Specifically, condition #A includes the following sub-conditions:
子条件#a：资源#B属于资源集合#A3，且资源#B不与资源#D(第四资源的一例)频分，资源#D是资源#B在时域单元#1(第一时域单元的一例)包括的至少一个候选资源中排除了资源#A的剩余候选资源，时域单元#1是资源#B所在时域单元；Sub-condition #a: resource #B belongs to resource set #A3, and resource #B is not frequency-divided with resource #D (an example of the fourth resource), resource #D is the remaining candidate resource of resource #B excluding resource #A from at least one candidate resource included in time domain unit #1 (an example of the first time domain unit), and time domain unit #1 is the time domain unit where resource #B is located;
子条件#b：资源#B属于资源集合#A3，且时域单元#1包括的候选资源的数量与一个时域单元可包括的候选资源的最大数量相等；Sub-condition #b: Resource #B belongs to resource set #A3, and the number of candidate resources included in time domain unit #1 is equal to the maximum number of candidate resources that can be included in a time domain unit;
子条件#c：资源#B不与资源#D频分；Sub-condition #c: Resource #B is not frequency-divided with resource #D;
子条件#d：资源#D的个数为0；Sub-condition #d: The number of resource #D is 0;
子条件#e：时域单元#1包括的候选资源的总数量与一个时域单元可包括的候选资源的最大数量相等。即时域单元#1包括的候选资源的数量等于时域单元#1包括的候选资源的最大数量。示例性的，对于上述子条件，包括：Sub-condition #e: The total number of candidate resources included in time domain unit #1 is equal to the maximum number of candidate resources that can be included in a time domain unit. That is, the number of candidate resources included in time domain unit #1 is equal to the maximum number of candidate resources included in time domain unit #1. Exemplarily, for the above sub-conditions, including:
资源#B属于资源集合#A3，可以理解为资源#B和资源集合#A3有重叠，或者，资源#B和资源集合#A3在时域上有重叠。或者，可以替换为：资源#B时域属于资源#A，或者资源#B和资源#A有重叠或者在时域上有重叠。资源#B不与资源#D频分，可以理解为，资源#B和资源#D在时域上不重叠。Resource #B belongs to resource set #A3, which can be understood as resource #B and resource set #A3 overlap, or resource #B and resource set #A3 overlap in the time domain. Alternatively, it can be replaced by: resource #B belongs to resource #A in the time domain, or resource #B and resource #A overlap or overlap in the time domain. Resource #B is not frequency-divided with resource #D, which can be understood as resource #B and resource #D do not overlap in the time domain.
时域单元#1是资源#B所在时域单元，可以理解为，时域单元#1是与资源#B重叠的时域单元。Time domain unit #1 is the time domain unit where resource #B is located. It can be understood that time domain unit #1 is a time domain unit overlapping with resource #B.
应理解，时隙#1包括的候选资源的最大数量为N-L+1，其中N为正整数，N为LTE-V传输的频域资源包括的子信道个数，L为第一资源的频域资源包括的子信道个数。It should be understood that the maximum number of candidate resources included in time slot #1 is N-L+1, where N is a positive integer, N is the number of sub-channels included in the frequency domain resources of LTE-V transmission, and L is the number of sub-channels included in the frequency domain resources of the first resources.
作为示例而非限定，终端#A的NR-V模块获取了资源集合#A3的频域范围，即频域起始位置和长度。频域长度可以理解为资源集合#A3包括的子信道个数，此时NR-V模块根据频域范围和频域长度即可确定一个时隙包括的候选单个时隙资源的数量。如图11所示，一个时隙包括4个子信道，资源集合#A3包括2个子信道，容易理解的是，由于候选资源应当包含连续的子信道，因此一个时隙包括3个资源#A，即一个时隙包括3个候选资源。终端#A通过子条件#a或子条件#b确定资源#C是否与资源集合#A3重叠。应理解，频域范围还可以为频域结束位置和长度，或者频域起始位置和结束位置，本申请在此不作限定。As an example and not a limitation, the NR-V module of terminal #A obtains the frequency domain range of resource set #A3, that is, the frequency domain starting position and length. The frequency domain length can be understood as the number of subchannels included in resource set #A3. At this time, the NR-V module can determine the number of candidate single time slot resources included in a time slot based on the frequency domain range and frequency domain length. As shown in Figure 11, a time slot includes 4 subchannels, and resource set #A3 includes 2 subchannels. It is easy to understand that since the candidate resources should contain continuous subchannels, a time slot includes 3 resources #A, that is, a time slot includes 3 candidate resources. Terminal #A determines whether resource #C overlaps with resource set #A3 through sub-condition #a or sub-condition #b. It should be understood that the frequency domain range can also be the frequency domain end position and length, or the frequency domain start position and end position, and this application is not limited here.
示例性的，资源集合#A3在子帧#1，子帧#1包括的候选资源的总数为N，假设资源集合#A3在子帧#1中包括的候选资源的个数小于N，则表示该子帧#1包括LTE-V传输占用的资源，和该子帧在时域上有重叠的资源#B不能使用。Exemplarily, resource set #A3 is in subframe #1, and the total number of candidate resources included in subframe #1 is N. Assuming that the number of candidate resources included in resource set #A3 in subframe #1 is less than N, it means that subframe #1 includes resources occupied by LTE-V transmission, and resource #B that overlaps with the subframe in the time domain cannot be used.
应理解，当终端#A的NR-V模块判定(确定)资源#A和资源#B满足条件#B中的至少一项子条件，即子条件#a，子条件#b、子条件#c、子条件#d，子条件#e中的至少一项子条件时，终端#A判定(确定)LTE-V的传输占用的资源和资源#B在时域上资源#B不重叠。It should be understood that when the NR-V module of terminal #A determines (confirms) that resource #A and resource #B satisfy at least one sub-condition in condition #B, that is, at least one sub-condition among sub-condition #a, sub-condition #b, sub-condition #c, sub-condition #d, and sub-condition #e, terminal #A determines (confirms) that the resources occupied by LTE-V transmission and resource #B do not overlap in the time domain.
对应地，作为示例而非限定，对于用于LTE-V传输的候选资源的资源#A，即资源集合#A3中的资源#A，终端#A根据资源#A和资源#B是否满足条件#B，来确定LTE-V传输占用的资源是否与资源#B重叠。 Correspondingly, as an example but not limitation, for resource #A which is a candidate resource for LTE-V transmission, that is, resource #A in resource set #A3, terminal #A determines whether the resources occupied by LTE-V transmission overlap with resource #B based on whether resource #A and resource #B meet condition #B.
具体而言，条件#B包括如下子条件：Specifically, condition #B includes the following sub-conditions:
子条件#a’：资源#B不属于资源集合#A3；Sub-condition #a’: Resource #B does not belong to resource set #A3;
子条件#b’：资源#B与资源#D频分，即资源#B与资源#D在时域上重叠；Sub-condition #b’: Resource #B and resource #D are frequency-separated, that is, resource #B and resource #D overlap in the time domain;
子条件#c’：时域单元#1包括的候选资源的数量小于一个时域单元可包括的候选资源的最大数量；Sub-condition #c’: the number of candidate resources included in time domain unit #1 is less than the maximum number of candidate resources that can be included in a time domain unit;
子条件#d’：资源#D的个数大于0；Sub-condition #d’: the number of resource #D is greater than 0;
应理解，时域单元#1包括的候选资源的最大数量为N-L+1，其中N为正整数，N为LTE-V传输的频域资源包括的子信道个数，L为第一资源的频域资源包括的子信道个数。It should be understood that the maximum number of candidate resources included in the time domain unit #1 is N-L+1, where N is a positive integer, N is the number of sub-channels included in the frequency domain resources of the LTE-V transmission, and L is the number of sub-channels included in the frequency domain resources of the first resources.
应理解，当终端#A的NR-V模块确定资源#A和资源#B满足条件#B中的至少一项子条件，即子条件#a’，子条件#b’、子条件#c’、子条件#d’中的至少一项子条件时，终端#A确定LTE-V传输占用的资源与资源#B有重叠。It should be understood that when the NR-V module of terminal #A determines that resource #A and resource #B satisfy at least one sub-condition in condition #B, that is, at least one sub-condition among sub-condition #a’, sub-condition #b’, sub-condition #c’, and sub-condition #d’, terminal #A determines that the resources occupied by LTE-V transmission overlap with resource #B.
需要说明的是，对于资源集合#A4或资源集合#A4中的资源#A，终端#A确定LTE-V传输占用的资源是否与资源#B重叠的方式与资源集合#A3相同，此处不再赘述。It should be noted that, for resource set #A4 or resource #A in resource set #A4, the way in which terminal #A determines whether the resources occupied by LTE-V transmission overlap with resource #B is the same as that for resource set #A3, and will not be repeated here.
在另一种可能的实现方式中，终端#A根据指示信息#1，确定资源#A，进而确定LTE-V传输占用的资源是否与资源#B重叠。具体而言，对于资源集合#A3或者资源集合#A4中的资源#A，终端#A根据资源集合#A1或者资源集合#A2中的资源#A确定LTE-V传输占用的资源是否与资源#B重叠。In another possible implementation, terminal #A determines resource #A according to indication information #1, and further determines whether the resources occupied by LTE-V transmission overlap with resource #B. Specifically, for resource #A in resource set #A3 or resource set #A4, terminal #A determines whether the resources occupied by LTE-V transmission overlap with resource #B according to resource #A in resource set #A1 or resource set #A2.
示例性的，如图12所示，资源#A为LTE-V传输占用的资源，即资源#A为资源集合#A1中的资源#A，或者，资源集合#A2中的资源#A，终端#A根据资源#A和资源#B是否满足条件#C，从而确定LTE-V传输占用的资源是否与资源#B不重叠。Exemplarily, as shown in Figure 12, resource #A is the resource occupied by LTE-V transmission, that is, resource #A is resource #A in resource set #A1, or resource #A in resource set #A2. Terminal #A determines whether the resources occupied by LTE-V transmission do not overlap with resource #B based on whether resource #A and resource #B meet condition #C.
具体而言，条件#C为资源#B与资源#A是时分复用的，即资源#B与资源#A在时域上不重叠。Specifically, condition #C is that resource #B and resource #A are time-division multiplexed, that is, resource #B and resource #A do not overlap in the time domain.
应理解，当资源#A和资源#B满足条件#C时，终端#A确定资源#B和LTE-V传输占用的资源不重叠。It should be understood that when resource #A and resource #B satisfy condition #C, terminal #A determines that resource #B and the resources occupied by LTE-V transmission do not overlap.
示例性的，终端#A获取了资源集合#A1，资源#B和资源集合#A1中的任意一个资源在时域上均不重叠，即资源#B和LTE-V传输占用的资源在时域上不重叠。或者，终端#A获取了资源集合#A2，资源#B和资源集合#A2中的任意一个资源在时域上均不重叠，即资源#B和LTE-V传输占用的资源在时域上不重叠。Exemplarily, terminal #A obtains resource set #A1, and resource #B does not overlap with any resource in resource set #A1 in the time domain, that is, resource #B does not overlap with the resources occupied by LTE-V transmission in the time domain. Alternatively, terminal #A obtains resource set #A2, and resource #B does not overlap with any resource in resource set #A2 in the time domain, that is, resource #B does not overlap with the resources occupied by LTE-V transmission in the time domain.
对应的，作为示例而非限定，资源#A为LTE-V传输占用的资源，即资源集合#A1或资源集合#A2中的资源#A，终端#A确定资源#A和资源#B是否满足条件#D，从而判定资源#A是否与资源#B重叠。Correspondingly, as an example but not a limitation, resource #A is the resource occupied by LTE-V transmission, that is, resource #A in resource set #A1 or resource set #A2. Terminal #A determines whether resource #A and resource #B meet condition #D, thereby determining whether resource #A overlaps with resource #B.
具体而言，条件#D为资源#B与资源#A是频分复用的，即资源#B与资源#A在时域上重叠。Specifically, condition #D is that resource #B and resource #A are frequency division multiplexed, that is, resource #B and resource #A overlap in the time domain.
应理解，当终端#A确定资源#A和资源#B满足条件#D时，终端#A确定LTE-V传输占用的资源和资源#B在时域上重叠。It should be understood that when terminal #A determines that resource #A and resource #B satisfy condition #D, terminal #A determines that the resources occupied by LTE-V transmission and resource #B overlap in the time domain.
示例性的，终端#A获取了资源集合#A1，资源#B和资源集合#A1中的至少一个资源在时域上有重叠，即资源#B和LTE-V传输占用的资源在时域上有重叠。或者，终端#A获取了资源集合#A2，资源#B和资源集合#A2中的至少一个资源在时域上有重叠，则资源#B和LTE-V传输占用的资源在时域上有重叠。Exemplarily, terminal #A obtains resource set #A1, and resource #B overlaps with at least one resource in resource set #A1 in the time domain, that is, resource #B overlaps with the resources occupied by LTE-V transmission in the time domain. Alternatively, terminal #A obtains resource set #A2, and resource #B overlaps with at least one resource in resource set #A2 in the time domain, then resource #B overlaps with the resources occupied by LTE-V transmission in the time domain.
需要说明的是，对于资源集合#A2中的资源#A，终端#A确定LTE-V传输占用的资源是否与资源#B重叠的方式与资源集合#A1相同，此处不再赘述。It should be noted that, for resource #A in resource set #A2, the way in which terminal #A determines whether the resources occupied by LTE-V transmission overlap with resource #B is the same as that for resource set #A1, and will not be repeated here.
S130，终端#A在资源#B上发送或者不发送NR-V数据对应的PSFCH。S130, terminal #A sends or does not send the PSFCH corresponding to the NR-V data on resource #B.
该发送NR-V数据对应的PSFCH即该发送NR-V数据对应的反馈信息，反馈信息承载于PSFCH中。The PSFCH corresponding to the sent NR-V data is feedback information corresponding to the sent NR-V data, and the feedback information is carried in the PSFCH.
NR-V数据对应的PSFCH，即使用NR无线接入***传输的PSFCH，或者使用NR-V无线接入***传输的PSFCH，或者可以为NR-V对应的PSFCH。The PSFCH corresponding to the NR-V data is the PSFCH transmitted using the NR wireless access system, or the PSFCH transmitted using the NR-V wireless access system, or it may be the PSFCH corresponding to NR-V.
在一种可能的实现方式中，对于资源集合#A3中的资源#A，或者，资源集合#A4中的资源#A，终端#A根据S120中的结果，确定是否发送NR-V数据对应的PSFCH。In one possible implementation, for resource #A in resource set #A3, or resource #A in resource set #A4, terminal #A determines whether to send the PSFCH corresponding to the NR-V data based on the result in S120.
作为示例而非限定，当资源#A与资源#B满足条件#A时，即LTE-V传输占用的资源与资源#B不重叠时，终端#A发送NR-V数据对应的PSFCH。As an example but not limitation, when resource #A and resource #B meet condition #A, that is, when the resources occupied by LTE-V transmission do not overlap with resource #B, terminal #A sends the PSFCH corresponding to NR-V data.
作为示例而非限定，当资源#A与资源#B满足条件#B时，即LTE-V传输占用的资源与资源#B重叠时，终端#A不发送NR-V数据对应的PSFCH。这里，不发送PSFCH可理解为停止发送PSFCH，取 消PSFCH，丢弃PSFCH。As an example but not a limitation, when resource #A and resource #B meet condition #B, that is, when the resources occupied by LTE-V transmission overlap with resource #B, terminal #A does not send the PSFCH corresponding to the NR-V data. Here, not sending PSFCH can be understood as stopping sending PSFCH. Deactivate PSFCH and discard PSFCH.
在另一种可能的实现方式中，对于资源集合#A1中的资源#A，或者，资源集合#A2中的资源#A，终端#A根据S120中的结果，确定是否发送NR-V数据对应的PSFCH。In another possible implementation, for resource #A in resource set #A1, or resource #A in resource set #A2, terminal #A determines whether to send the PSFCH corresponding to the NR-V data based on the result in S120.
作为示例而非限定，当资源#A与资源#B满足条件#C时，即LTE-V传输占用的资源与资源#B不重叠时，终端#A发送NR-V数据对应的PSFCH。As an example but not a limitation, when resource #A and resource #B meet condition #C, that is, when the resources occupied by LTE-V transmission do not overlap with resource #B, terminal #A sends the PSFCH corresponding to NR-V data.
作为示例而非限定，当资源#A与资源#B满足条件#D时，即LTE-V传输占用的资源与资源#B重叠时，终端#A不发送NR-V数据对应的PSFCH。As an example and not a limitation, when resource #A and resource #B satisfy condition #D, that is, when the resources occupied by LTE-V transmission overlap with resource #B, terminal #A does not send the PSFCH corresponding to NR-V data.
在另一种可能的实现方式中，如图14所示，指示信息#1指示的资源#A的时域范围不包括资源#B的时域位置，容易理解的是，终端#A无法判断资源#A是否与资源#B重叠，进而终端#A无法判断LTE-V传输占用的资源是否与资源#B重叠。In another possible implementation, as shown in FIG14 , the time domain range of resource #A indicated by indication information #1 does not include the time domain position of resource #B. It is easy to understand that terminal #A cannot determine whether resource #A overlaps with resource #B, and thus terminal #A cannot determine whether the resources occupied by LTE-V transmission overlap with resource #B.
示例性的，在此情况下，终端#A不发送NR-V数据对应的PSFCH。此时可以避免NR-V的PSFCH对LTE-V传输的性能产生影响。Exemplarily, in this case, terminal #A does not send the PSFCH corresponding to the NR-V data. At this time, the impact of the NR-V PSFCH on the performance of LTE-V transmission can be avoided.
示例性的，在此情况下，终端#A发送NR-V数据对应的PSFCH。此时在PSFCH资源和LTE-V传输占用的资源在时域上不重叠时，NR-V传输可以获取PSFCH带来的性能。Exemplarily, in this case, terminal #A sends the PSFCH corresponding to the NR-V data. At this time, when the PSFCH resources and the resources occupied by the LTE-V transmission do not overlap in the time domain, the NR-V transmission can obtain the performance brought by the PSFCH.
示例性的，在此情况下，终端#A获取基站的配置信息或者预配置信息，用于指示终端#A是否发送NR-V数据对应的PSFCH。Exemplarily, in this case, terminal #A obtains configuration information or pre-configuration information of the base station to indicate whether terminal #A sends the PSFCH corresponding to the NR-V data.
应理解，终端#A在MAC层上执行方法100的所有步骤，或者，终端#A在PHY层上执行方法100的所有步骤，本申请实施例对此不作限定。It should be understood that terminal #A executes all steps of method 100 on the MAC layer, or terminal #A executes all steps of method 100 on the PHY layer, and the embodiments of the present application are not limited to this.
在一种可能的实现方式中，当终端#A确定资源#B和LTE-V传输占用的资源有重叠，且LTE-V传输对应的优先级值低于一个阈值，则不发送NR-V数据对应的PSFCH。该阈值为预设或配置的。可以预配置或网络设备配置。In one possible implementation, when terminal #A determines that resource #B and resources occupied by LTE-V transmission overlap, and the priority value corresponding to LTE-V transmission is lower than a threshold, the PSFCH corresponding to NR-V data is not sent. The threshold is preset or configured. It can be pre-configured or configured by the network device.
在另一种可能的实现方式中，当终端#A确定资源#B和LTE-V传输占用的资源有重叠，且LTE-V传输对应的优先级值高于一个阈值，则发送NR-V数据对应的PSFCH。In another possible implementation, when terminal #A determines that resource #B overlaps with resources occupied by LTE-V transmission, and the priority value corresponding to LTE-V transmission is higher than a threshold, the PSFCH corresponding to the NR-V data is sent.
容易理解的是，终端#A不发送NR-V数据对应的PSFCH，则对应的接收终端没有接收到NR-V数据对应的PSFCH。It is easy to understand that if terminal #A does not send the PSFCH corresponding to the NR-V data, the corresponding receiving terminal does not receive the PSFCH corresponding to the NR-V data.
作为示例而非限定，接收终端在接收PSFCH前，确定PSFCH资源和LTE-V传输占用的资源有重叠且没有接收到该NR-V数据对应的PSFCH的总数量大于一个阈值。则接收终端不重传该NR-V数据。具体的，counter计数初始值为0，接收终端确定PSFCH资源和LTE-V传输占用的资源有重叠且没有接收到PSFCH，则counter计数值加1。当counter计数值大于一个阈值，该接收终端不重传该NR-V数据。As an example and not a limitation, before receiving PSFCH, the receiving terminal determines that the PSFCH resources and the resources occupied by LTE-V transmission overlap and the total number of PSFCHs corresponding to the NR-V data that are not received is greater than a threshold. Then the receiving terminal does not retransmit the NR-V data. Specifically, the initial value of the counter is 0. When the receiving terminal determines that the PSFCH resources and the resources occupied by LTE-V transmission overlap and the PSFCH is not received, the counter count value is increased by 1. When the counter count value is greater than a threshold, the receiving terminal does not retransmit the NR-V data.
作为示例而非限定，接收终端在接收PSFCH前，确定PSFCH资源和LTE-V传输占用的资源有重叠且连续没有接收到该NR-V数据对应PSFCH的数量大于一个阈值，该接收终端不重传该NR-V数据。具体的，counter计数初始值为0，接收终端确定PSFCH资源和LTE-V传输占用的资源有重叠且没有接收到PSFCH，则counter计数值加1。当counter计数值大于一个阈值，该接收终端不重传该NR-V数据。该counter计数是连续的。当前一个PSFCH传输时PSFCH资源和LTE-V传输占用的资源没有重叠，则counter计数值重新置0。As an example and not a limitation, before receiving the PSFCH, the receiving terminal determines that the PSFCH resources and the resources occupied by the LTE-V transmission overlap and the number of PSFCHs corresponding to the NR-V data that have not been received continuously is greater than a threshold, and the receiving terminal does not retransmit the NR-V data. Specifically, the initial value of the counter count is 0. When the receiving terminal determines that the PSFCH resources and the resources occupied by the LTE-V transmission overlap and the PSFCH is not received, the counter count value is increased by 1. When the counter count value is greater than a threshold, the receiving terminal does not retransmit the NR-V data. The counter count is continuous. When the PSFCH resources and the resources occupied by the LTE-V transmission do not overlap during the previous PSFCH transmission, the counter count value is reset to 0.

That is, terminal #B determines that data #1 requires HARQ feedback, and then sends indication information #2 to indicate enabling HARQ feedback of data #1.
示例性的，使能/去使能HARQ反馈的字段为1比特，其中取值为“1”表示使能HARQ反馈，取值为“0”表示去使能HARQ反馈。指示信息#2指示使能HARQ反馈，即将第二级SCI中的“使能/去使能HARQ反馈的字段”的取值设置为1。Exemplarily, the field for enabling/disabling HARQ feedback is 1 bit, wherein a value of "1" indicates enabling HARQ feedback, and a value of "0" indicates disabling HARQ feedback. Indication information #2 indicates enabling HARQ feedback, i.e., the value of the "field for enabling/disabling HARQ feedback" in the second-level SCI is set to 1.
作为示例而非限定，终端#B根据数据#1是否需要HARQ反馈来确定使能HARQ反馈或去使能HARQ反馈。在这种方式下，已经确定了PSFCH传输不影响LTE-V传输，因此PSFCH传输可以根据NR-V的需求来进行，不需要因为LTE-V传输而改变原有的终端实现方法。As an example but not limitation, terminal #B determines whether to enable or disable HARQ feedback based on whether data #1 requires HARQ feedback. In this way, it has been determined that PSFCH transmission does not affect LTE-V transmission, so PSFCH transmission can be performed according to NR-V requirements, and there is no need to change the original terminal implementation method due to LTE-V transmission.
作为示例而非限定，当资源#A与资源#B满足条件#B时，即LTE-V传输占用的资源与资源#B重叠时，终端#B发送指示信息#3(第三指示信息的一例)，指示信息#3承载于第二级SCI中，用于指示去使能HARQ反馈。即，终端#B发送指示信息#2，指示去使能数据#1的HARQ反馈。此时，终端#A接收了数据#1则不需要反馈HARQ信息，也就不需要判断PSFCH传输是否影响LTE-V传输，节省了终端#A的功耗。另外，避免终端#B在接收LTE-V传输时被PSFCH传输影响，例如PSFCH AGC符号对应的LTE-V功率的调整超出上限。在另一种可能的实现方式中，对于资源集合#A1中的资源#A，或者，资源集合#A2中的资源#A，终端#B根据S220中的判定结果，确定是否在第二级SCI中指示使能HARQ反馈，该HARQ为承载在资源#B上的反馈信息。As an example but not a limitation, when resource #A and resource #B meet condition #B, that is, when the resources occupied by LTE-V transmission overlap with resource #B, terminal #B sends indication information #3 (an example of the third indication information), and indication information #3 is carried in the second-level SCI to indicate the disabling of HARQ feedback. That is, terminal #B sends indication information #2 to indicate the disabling of HARQ feedback of data #1. At this time, terminal #A does not need to feedback HARQ information after receiving data #1, and does not need to judge whether PSFCH transmission affects LTE-V transmission, which saves power consumption of terminal #A. In addition, it prevents terminal #B from being affected by PSFCH transmission when receiving LTE-V transmission, for example, the adjustment of LTE-V power corresponding to PSFCH AGC symbol exceeds the upper limit. In another possible implementation, for resource #A in resource set #A1, or resource #A in resource set #A2, terminal #B determines whether to indicate enabling HARQ feedback in the second-level SCI according to the determination result in S220, and the HARQ is feedback information carried on resource #B.
作为示例而非限定，当资源#A与资源#B满足条件#C时，即LTE-V传输占用的资源与资源#B不重叠时，终端#B发送指示信息#2(第二指示信息的一例)，指示信息#2承载于第二级SCI中，用于指示使能HARQ反馈。As an example but not limitation, when resource #A and resource #B meet condition #C, that is, the resources occupied by LTE-V transmission do not overlap with resource #B, terminal #B sends indication information #2 (an example of the second indication information), and indication information #2 is carried in the second-level SCI to indicate enabling of HARQ feedback.
作为示例而非限定，当资源#A与资源#B满足条件#D时，即LTE-V传输占用的资源与资源#B重叠时，终端#B发送指示信息#3(第三指示信息的一例)，指示信息#3承载于第二级SCI中，用于指示在去使能HARQ反馈。As an example but not limitation, when resource #A and resource #B meet condition #D, that is, when the resources occupied by LTE-V transmission overlap with resource #B, terminal #B sends indication information #3 (an example of the third indication information), and indication information #3 is carried in the second-level SCI and is used to indicate that HARQ feedback is disabled.
在另一种可能的实现方式中，数据本身不需要HARQ使能，终端#B指示去使能HARQ反馈，具体而言，在发送调度数据的第二级SCI时，在第二级SCI中包括的HARQ使能字段指示“去使能HARQ反馈”。In another possible implementation, the data itself does not require HARQ enabling, and terminal #B indicates to disable HARQ feedback. Specifically, when sending the second-level SCI for scheduling data, the HARQ enabling field included in the second-level SCI indicates "disable HARQ feedback".
应理解，终端#B在MAC层上执行方法200的所有步骤，或者，终端#B在PHY层上执行方法200的所有步骤，本申请实施例对此不作限定。It should be understood that terminal #B executes all steps of method 200 on the MAC layer, or terminal #B executes all steps of method 200 on the PHY layer, and the embodiments of the present application are not limited to this.

Specifically, during the resource selection process, terminal #C only selects resources whose associated resource #B meets condition #A, and determines a candidate resource set, any candidate resource in the candidate resource set can be resource #D (that is, the candidate resource selected in the candidate resource combination is resource #D). Alternatively, during the resource selection process, when the MAC layer receives the candidate resource set, it selects the candidate resource whose associated resource #B meets condition #A for sending NR-V data.
作为示例而非限定，当资源#A与资源#B满足条件#B时，即LTE-V传输占用的资源与资源#B重叠时，终端#C不使用资源#D发送NR-V数据，或者，降低使用资源#D发送NR-V数据的优先级。具体的，在资源选择过程中，终端#C不选择关联的资源#B满足条件#B的资源，从而确定的候选资源集合中不包括资源#D。或者，在资源选择过程中，MAC层接收到候选资源集合时，不选择关联的资源#B满足条件#B的候选资源用于发送NR-V数据；或者，先选择关联的资源#B不满足条件#B的候选资源用于发送NR-V数据，该关联的资源#B不满足条件#B的候选资源没有了，再选择关联的资源#B或者满足条件#B的候选资源用于发送NR-V数据。As an example and not a limitation, when resource #A and resource #B meet condition #B, that is, when the resources occupied by LTE-V transmission overlap with resource #B, terminal #C does not use resource #D to send NR-V data, or reduces the priority of using resource #D to send NR-V data. Specifically, during the resource selection process, terminal #C does not select the resource associated with resource #B that meets condition #B, so that resource #D is not included in the determined candidate resource set. Alternatively, during the resource selection process, when the MAC layer receives the candidate resource set, the candidate resource associated with resource #B that meets condition #B is not selected for sending NR-V data; or, the candidate resource associated with resource #B that does not meet condition #B is first selected for sending NR-V data, and the candidate resource associated with resource #B that does not meet condition #B is no longer available, and then the associated resource #B or the candidate resource that meets condition #B is selected for sending NR-V data.
在另一种可能的实现方式中，对于资源集合#A1中的资源#A，或者，资源集合#A2中的资源#A，终端#C根据S320中的结果，确定使用或者不使用资源#D发送NR-V数据。即终端#C根据S320中的结果进行资源选择。即终端#C根据S320中的结果进行资源选择。In another possible implementation, for resource #A in resource set #A1 or resource #A in resource set #A2, terminal #C determines whether to use or not to use resource #D to send NR-V data according to the result in S320. That is, terminal #C performs resource selection according to the result in S320. That is, terminal #C performs resource selection according to the result in S320.
作为示例而非限定，当资源#A与资源#B满足条件#C时，即LTE-V传输占用的资源与资源#B不重叠时，终端#C使用或者优先使用资源#D发送NR-V数据。具体的，在资源选择过程中，终端#C只选择关联的资源#B满足条件#C的资源，确定一个候选资源集合，该候选资源集合中任一个候选资源均可以为资源#D(即该候选资源结合中被选择的候选资源为资源#D)。或者，在资源选择过程中，MAC层接收到候选资源集合时，选择关联的资源#B满足条件#C的候选资源用于发送NR-V数据。As an example but not limitation, when resource #A and resource #B meet condition #C, that is, when the resources occupied by LTE-V transmission do not overlap with resource #B, terminal #C uses or gives priority to resource #D to send NR-V data. Specifically, during the resource selection process, terminal #C only selects resources whose associated resource #B meets condition #C, and determines a candidate resource set, any candidate resource in the candidate resource set can be resource #D (that is, the candidate resource selected in the candidate resource combination is resource #D). Alternatively, during the resource selection process, when the MAC layer receives the candidate resource set, it selects the candidate resource whose associated resource #B meets condition #C for sending NR-V data.
作为示例而非限定，当资源#A与资源#B满足条件#D时，即LTE-V传输占用的资源与资源#B重叠时，终端#C不使用资源#D发送NR-V数据，或者，降低使用资源#D发送NR-V数据的优先级。具体的，在资源选择过程中，终端#C不选择关联的资源#B满足条件#D的资源，从而确定的候选资源集合中不包括资源#D。或者，在资源选择过程中，MAC层接收到候选资源集合时，不选择关联的资源#B满足条件#D的候选资源用于发送NR-V数据；或者，先选择关联的资源#B不满足条件#D的候选资源用于发送NR-V数据，该关联的资源#B不满足条件#D的候选资源没有了，再选择关联的资源#B或者满足条件#B的候选资源用于发送NR-V数据。As an example and not a limitation, when resource #A and resource #B meet condition #D, that is, when the resources occupied by LTE-V transmission overlap with resource #B, terminal #C does not use resource #D to send NR-V data, or reduces the priority of using resource #D to send NR-V data. Specifically, during the resource selection process, terminal #C does not select the resource associated with resource #B that meets condition #D, so that resource #D is not included in the determined candidate resource set. Alternatively, during the resource selection process, when the MAC layer receives the candidate resource set, the candidate resource associated with resource #B that meets condition #D is not selected for sending NR-V data; or, the candidate resource associated with resource #B that does not meet condition #D is first selected for sending NR-V data, and the candidate resource associated with resource #B that does not meet condition #D is no longer available, and then the associated resource #B or the candidate resource that meets condition #B is selected for sending NR-V data.
应理解，使用或者优先使用资源#D发送NR-V数据这一步骤可以由终端#C在不同的阶段执行。例如，这一步骤在进行资源选择的过程中执行，在此阶段，使用资源#D应理解为选择资源#D，优先使用资源#D应理解为优先选择资源#D。It should be understood that the step of using or giving priority to resource #D to send NR-V data can be performed by terminal #C at different stages. For example, this step is performed during the process of resource selection. At this stage, using resource #D should be understood as selecting resource #D, and giving priority to using resource #D should be understood as giving priority to selecting resource #D.
示例性的，终端#C在进行资源选择的过程中，只选择对应的资源#B与LTE-V传输占用的资源在时域上不重叠的候选资源。该步骤在PHY层执行(则对应的S310，S320均在PHY层执行)。当PHY层将该候选资源的集合上报给MAC层。MAC层在该候选资源的集合中选择使用其中一个资源。该其中一个资源可以理解为资源#D。Exemplarily, during the resource selection process, terminal #C only selects candidate resources whose corresponding resource #B does not overlap with the resources occupied by LTE-V transmission in the time domain. This step is performed at the PHY layer (the corresponding S310 and S320 are both performed at the PHY layer). When the PHY layer reports the set of candidate resources to the MAC layer. The MAC layer selects one of the resources in the set of candidate resources for use. One of the resources can be understood as resource #D.
示例性的，终端#C在进行资源选择的过程中，确定候选资源集合包括对应的资源#B与LTE-V传输占用的资源在时域上不重叠的候选资源的子集合和对应的资源#B与LTE-V传输占用的资源在时域上重叠的候选资源的子集合。该步骤在PHY层执行(则对应的S310，S320均在PHY层执行)。当PHY层将该候选资源的集合上报给MAC层。MAC层在该对应的资源#B与LTE-V传输占用的资源在时域上不重叠的候选资源的子集合中选择使用其中一个资源。该其中一个资源可以理解为资源#D。Exemplarily, during the process of resource selection, terminal #C determines that the candidate resource set includes a subset of candidate resources whose corresponding resource #B does not overlap with the resources occupied by LTE-V transmission in the time domain, and a subset of candidate resources whose corresponding resource #B overlaps with the resources occupied by LTE-V transmission in the time domain. This step is performed at the PHY layer (the corresponding S310 and S320 are both performed at the PHY layer). When the PHY layer reports the set of candidate resources to the MAC layer. The MAC layer selects to use one of the resources from the subset of candidate resources whose corresponding resource #B does not overlap with the resources occupied by LTE-V transmission in the time domain. One of the resources can be understood as resource #D.
示例性的，在确定了候选资源集合后，MAC层在选择资源时，优先选择对应的资源#B与LTE-V传输占用的资源在时域上不重叠的候选资源。该步骤在PHY层执行(则对应的S320在MAC层执行)。Exemplarily, after determining the candidate resource set, the MAC layer, when selecting resources, gives priority to selecting candidate resources whose corresponding resource #B does not overlap with the resources occupied by LTE-V transmission in the time domain. This step is performed at the PHY layer (the corresponding S320 is performed at the MAC layer).
示例性的，在确定了候选资源集合后，MAC层在选择资源时，对于需要使能HARQ的数据，优先选择对应的资源#B与LTE-V传输占用的资源在时域上不重叠的候选资源。该步骤在PHY层执行(则 对应的S320在MAC层执行)。对于HARQ去使能的数据，在资源选择过程中不需要有任何限制。For example, after determining the candidate resource set, when selecting resources, the MAC layer gives priority to selecting candidate resources whose corresponding resource #B does not overlap with the resources occupied by LTE-V transmission in the time domain for data that needs to enable HARQ. This step is performed at the PHY layer (then The corresponding S320 is executed at the MAC layer.) For HARQ disabled data, there is no need for any restriction in the resource selection process.
示例性的，这一步骤在资源选择结束后执行，在此阶段，使用资源#D应理解为使用资源#D，优先使用资源#D应理解为优先使用资源#D，本申请对此不作限定。Exemplarily, this step is performed after the resource selection is completed. At this stage, using resource #D should be understood as using resource #D, and prioritizing the use of resource #D should be understood as prioritizing the use of resource #D. This application does not limit this.
在一种可能的实现方式中，终端#C根据指示信息#1，确定LTE-V传输占用的资源和资源#D不重叠且LTE-V传输占用的资源和资源#B不重叠，则终端#C使用或者优先使用资源#D发送NR-V数据。In one possible implementation, terminal #C determines, based on indication information #1, that the resources occupied by LTE-V transmission and resource #D do not overlap and that the resources occupied by LTE-V transmission and resource #B do not overlap, then terminal #C uses or prioritizes the use of resource #D to send NR-V data.
在另一种可能的实现方式中，终端#C根据指示信息#1，确定LTE-V传输占用的资源和资源#D重叠且LTE-V传输占用的资源和资源#B重叠，则终端#C不使用或者降低使用资源#D发送NR-V数据的优先级。In another possible implementation, terminal #C determines, based on indication information #1, that the resources occupied by LTE-V transmission overlap with resource #D and that the resources occupied by LTE-V transmission overlap with resource #B, then terminal #C does not use or reduces the priority of using resource #D to send NR-V data.
作为示例而非限定，终端#C使用资源#D发送NR-V数据，该资源#D也满足S320中所述的方法，即资源#D和LTE-V传输占用的资源在时域上不重叠。此时用于发送NR-V数据的资源和用于发送NR-V数据的反馈信息的资源均不影响LTE-V的传输。本申请实施例中，所述资源#B和LTE-V传输占用的资源是否重叠的确定方法也适用于资源#D。As an example but not limitation, terminal #C uses resource #D to send NR-V data, and resource #D also satisfies the method described in S320, that is, resource #D and the resources occupied by LTE-V transmission do not overlap in the time domain. At this time, the resources used to send NR-V data and the resources used to send feedback information for NR-V data do not affect the transmission of LTE-V. In an embodiment of the present application, the method for determining whether the resources occupied by resource #B and LTE-V transmission overlap is also applicable to resource #D.
