请参见图2，图2是本申请实施例提供的一种信息指示方法的流程图，该方法由终端执行，该终端比如为NR终端等。如图2所示，该方法包括如下步骤：Please refer to FIG. 2. FIG. 2 is a flow chart of an information indication method provided by an embodiment of the present application. The method is executed by a terminal, such as an NR terminal. As shown in Figure 2, the method includes the following steps:

步骤21：终端发送或者接收以下至少一项：第一控制信息、第二控制信息。Step 21: The terminal sends or receives at least one of the following: first control information and second control information.

本实施例中，第一控制信息承载在第一控制信道或者第一共享信道上。第二控制信息承载在第一共享信道上。In this embodiment, the first control information is carried on the first control channel or the first shared channel. The second control information is carried on the first shared channel.

需指出的，第一控制信息和第二控制信息实质上是旁链路控制信息(Sidelink Control Information，SCI)，但与相关技术中的SCI不同。第一控制信道实质上是物理旁链路控制信道(Physical Sidelink Control Channel，PSCCH)，但与相关技术中的PSCCH不同，为了避免与相关技术中的PSCCH混淆，以下有些相关描述中写成了PSCCH-1。第一共享信道实质上是物理旁链路共享信道(Physical Sidelink Shared Channel，PSSCH)，但与相关技术中的PSSCH不同，为了避免与相关技术中的PSSCH混淆，以下有些相关描述中写成了PSSCH-1。It should be pointed out that the first control information and the second control information are essentially sidelink control information (Sidelink Control Information, SCI), but they are different from the SCI in the related art. The first control channel is essentially a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH), but it is different from the PSCCH in the related art. In order to avoid confusion with the PSCCH in the related art, some of the following related descriptions are written as PSCCH- 1. The first shared channel is essentially a physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH), but it is different from the PSSCH in the related technology. In order to avoid confusion with the PSSCH in the related technology, some of the following related descriptions are written as PSSCH- 1.

可选地，第一控制信息和/或第二控制信息为终端发送的第三控制信息的增强信息。由于第三控制信息可以指示的信息较少，因此引入第一控制信息和/或第二控制信息来指示更多的信息。以NR终端为例，第三控制信息可以采用LTE sidelink中的SCI格式(format)1，以使得LTE终端可以解码成功NR终端发送的第三控制信息，并获得第三控制信息指示的资源预留相关信息用于资源选择，从而实现与LTE终端的同频共存。但是由于第三控制信息可以指示的信息较少，因此引入第一控制信息和/或第二控制信息来指示更多的信息，从而保证工作在共存频段的NR终端的性能。其中，第三控制信息主要用于LTE终端可以读取到NR终端的资源预留信息来进行资源选择，此情况下，其他NR终端也可以解码该NR终端的第三控制信息来获取资源预留信息。第一控制信息和/或第二控制信息主要用于其他NR终端读取到该NR终端的资源预留信息来进行资源选择以及接收数据、HARQ反馈等。Optionally, the first control information and/or the second control information is enhancement information of the third control information sent by the terminal. Since the third control information may indicate less information, the first control information and/or the second control information are introduced to indicate more information. Taking the NR terminal as an example, the third control information can adopt the SCI format (format) 1 in the LTE sidelink, so that the LTE terminal can decode the third control information successfully sent by the NR terminal, and obtain the resource reservation indicated by the third control information The relevant information is used for resource selection, so as to realize co-frequency coexistence with LTE terminals. However, since the third control information may indicate less information, the first control information and/or the second control information are introduced to indicate more information, so as to ensure the performance of the NR terminal working in the co-existing frequency band. Wherein, the third control information is mainly used for the LTE terminal to read the resource reservation information of the NR terminal for resource selection. In this case, other NR terminals can also decode the third control information of the NR terminal to obtain the resource reservation. information. The first control information and/or the second control information are mainly used by other NR terminals to read the resource reservation information of the NR terminal to perform resource selection, receive data, HARQ feedback, and the like.

第三控制信息承载在第二控制信道上。第三控制信息实质上是旁链路控制信息SCI，但与相关技术中的SCI不同，为避免与相关技术中的SCI混淆，以下有些相关描述中写成了SA。第二控制信道实质上是物理旁链路控制信道PSCCH，但与相关技术中的PSCCH不同，为避免与相关技术中的PSCCH混淆，以下有些相关描述中写成了PSCCH_SA。The third control information is carried on the second control channel. The third control information is essentially the sidelink control information SCI, but it is different from the SCI in the related art. In order to avoid confusion with the SCI in the related art, some related descriptions below are written as SA. The second control channel is essentially the physical sidelink control channel PSCCH, but it is different from the PSCCH in the related art. In order to avoid confusion with the PSCCH in the related art, some related descriptions below are written as PSCCH_SA.

下面结合具体实例对本申请进行详细说明。The present application will be described in detail below in conjunction with specific examples.

实例1Example 1

在NR终端发送控制信息SA，用以兼容LTE Sidelink的资源选择规则的基础上，由于SA的预留比特数有限，导致可以指示的内容有限，因此需要发送第一控制信息。第一控制信息承载在PSCCH-1上。On the basis of the control information SA sent by the NR terminal to be compatible with the resource selection rules of LTE Sidelink, due to the limited number of reserved bits of SA, the content that can be indicated is limited, so the first control information needs to be sent. The first control information is carried on PSCCH-1.

首先，第一控制信息可以重用/复用NR R16/R17的1 ^st SCI设计，这样可以在SA与PSSCH频域分离的情况下，重用/复用NR R16/R17的帧结构等设计，从而兼容NR R16/R17终端。 First of all, the first control information can reuse/multiplex the ^1st SCI design of NR R16/R17, so that the frame structure of NR R16/R17 can be reused/multiplexed in the case of SA and PSSCH frequency domain separation, so as to be compatible NR R16/R17 terminal.

其次，在不考虑兼容NR R16/R17终端的情况下，在控制信息SA没有指示PSFCH overhead、Beta_offset等信息的情况下，可以由第一控制信息来发送。在存在第二控制信息指示部分控制信息的情况下，第一控制信息可以仅发送关于解调第二控制信息的内容等，例如PSFCH overhead、Beta_offset以及目的ID等信息。在不存在第二控制信息的情况下，第一控制信息可以发送除了SA以外的所有控制信息，此时不再需要指示Beta_offset以及第二控制信息format等内容。Secondly, in the case of compatible NR R16/R17 terminals, if the control information SA does not indicate PSFCH overhead, Beta_offset and other information, it can be sent by the first control information. In the case where the second control information indicates part of the control information, the first control information may only send content related to demodulation of the second control information, such as PSFCH overhead, Beta_offset, and destination ID. In the case that there is no second control information, the first control information can send all control information except SA, and it is no longer necessary to indicate Beta_offset and second control information format and other contents.

如图3和图4所示，SA可以在整个slot发送，第一控制信息可以在第二个符号symbol发送。在发送内容较多的情况下，第一控制信息可以占据整个带宽，如图3所示，也可以占据其中N个子信道，如图4所示的占据子信道Sub1和Sub2。如图4所示，在存在第二控制信息的情况下，第二控制信息可以在第四个symbol发送。As shown in Figure 3 and Figure 4, the SA can be sent in the entire slot, and the first control information can be sent in the second symbol. In the case of a lot of content to be sent, the first control information may occupy the entire bandwidth, as shown in FIG. 3 , or may occupy N subchannels, as shown in FIG. 4 , occupying subchannels Sub1 and Sub2. As shown in FIG. 4 , if there is second control information, the second control information may be sent in the fourth symbol.

实例2Example 2

此时，如果不再需要考虑第一控制信息的占用bit数过多的问题，第一控制信息可以发送除SA以外的所有控制信息。此时，如图3所示，第一控制信息可以考虑频域上占据整个带宽，计算TBS时可以不再考虑第二个symbol。如果占据部分子信道，SA需要Beta_offset指示，用于计算第一控制信息所占用的RE数。At this time, if it is no longer necessary to consider the problem of too many occupied bits of the first control information, the first control information can send all control information except SA. At this time, as shown in FIG. 3 , the first control information may occupy the entire bandwidth in the frequency domain, and the second symbol may not be considered when calculating the TBS. If some sub-channels are occupied, the SA needs a Beta_offset indication, which is used to calculate the number of REs occupied by the first control information.

实例3Example 3

以NR终端为例，在重用/复用NR的两SCI设计时，可以发送第二控制信息。第二控制信息的指示域可以重用NR 2 ^nd SCI的指示域，且承载在PSSCH-1上。第二控制信息的format及Beta_offset指示由第一控制信息指示。 Taking the NR terminal as an example, when the two SCI designs of NR are reused/multiplexed, the second control information may be sent. The indication field of the second control information may reuse the indication field of the NR 2 ^nd SCI and be carried on the PSSCH-1. The format and Beta_offset indications of the second control information are indicated by the first control information.

此时，第二控制信息可以从第四个symbol开始映射，如图5所示；或者，从没有用于DMRS的符号的第一个符号开始映射，如图5所示；或者，从承载第一控制信息的符号开始映射，与第一控制信息FDM，如图6所示。At this time, the second control information can start mapping from the fourth symbol, as shown in Figure 5; or, start mapping from the first symbol that is not used for DMRS symbols, as shown in Figure 5; A symbol of control information starts to be mapped and FDM with the first control information, as shown in FIG. 6 .

实例4Example 4

一种NR终端的第一控制信息的格式1可以如下所示：A format 1 of the first control information of an NR terminal may be as follows:

ⅴ)DMRS pattern指示域；比如，用于DMRS具体采用哪一种pattern。ⅴ) DMRS pattern indication field; for example, which pattern is used for DMRS.

ⅵ)第二控制信息的格式指示域；比如，用于指示可能存在的下一SCI即第二控制信息的格式。ⅵ) The format indication field of the second control information; for example, it is used to indicate the format of the second control information which may be the next SCI.

ⅷ)DMRS port数量指示域；比如，用于指示port数量。ⅷ) DMRS port number indication field; for example, used to indicate the number of ports.

ⅸ)MCS指示域；比如，用于指示MCS等级。ⅸ) MCS indication field; for example, it is used to indicate the MCS level.

xi)PSFCH overhead指示域；比如，用于指示PSFCH overhead相关信息。xi) PSFCH overhead indication field; for example, used to indicate PSFCH overhead related information.

此时，第一控制信息与R16 NR 1st SCI相同，适用于兼容R16 NR的情况。NR终端发送的SA，可以仅用于LTE终端识别NR终端的预留资源，进行资源选择，达到同频共存的目的。At this time, the first control information is the same as R16 NR 1st SCI, which is applicable to the case of compatibility with R16 NR. The SA sent by the NR terminal can only be used by the LTE terminal to identify the reserved resources of the NR terminal and perform resource selection to achieve the purpose of coexistence at the same frequency.

实例5Example 5

一种NR终端的第一控制信息的格式2可以如下所示：A format 2 of the first control information of an NR terminal may be as follows:

ⅰ)DMRS pattern指示域；比如，用于DMRS具体采用哪一种pattern。ⅰ) DMRS pattern indication field; for example, which pattern is used for DMRS.

ⅱ)第二控制信息的格式指示域；比如，用于指示可能存在的下一SCI即第二控制信息的格式。ii) The format indication field of the second control information; for example, it is used to indicate the format of the second control information which may be the next SCI.

ⅲ)Beta_offset指示域；比如，用于指示确定第一共享信道上承载的控制信息的相关信息，比如计算调制符号数等信息的中间量。iii) Beta_offset indication field; for example, it is used to indicate relevant information for determining the control information carried on the first shared channel, such as calculating the intermediate amount of information such as the number of modulation symbols.

ⅳ)DMRS port数量指示域；比如，用于指示port数量。iv) DMRS port number indication field; for example, used to indicate the number of ports.

ⅴ)额外MCS指示域；比如，用于额外进行MCS指示。v) Additional MCS indication field; eg, for additional MCS indication.

此时，相对于实例4，第一控制信息仅发送SA没有发送的信息。如果DMRS pattern定义为重用/复用LTE DMRS pattern，此时还可以去掉DMRS pattern指示域和/或DMRS port数量指示域。At this time, relative to Example 4, the first control information only sends information that is not sent by the SA. If the DMRS pattern is defined as a reuse/multiplex LTE DMRS pattern, the DMRS pattern indication field and/or the DMRS port number indication field can also be removed at this time.

实例6Example 6

一种NR终端的第一控制信息的格式3可以如下所示：A format 3 of the first control information of an NR terminal may be as follows:

xii)HARQ进程关联指示域；比如，用于指示多个HARQ进程内的预留资源属于同一个TB，或者SL进程，MAC PDU(协议数据单元)等。xii) HARQ process association indication field; for example, it is used to indicate that the reserved resources in multiple HARQ processes belong to the same TB, or SL process, MAC PDU (protocol data unit), etc.

此时，第一控制信息与R16 NR 1st SCI相同，适用于兼容R16 NR的情况。同时，可以在利用多个HARQ进程关联同一TB的方式进行非周期预留时，在预留比特中增加指示域指示HARQ关联指示。At this time, the first control information is the same as R16 NR 1st SCI, which is applicable to the case of compatibility with R16 NR. At the same time, when aperiodic reservation is performed in the manner that multiple HARQ processes are associated with the same TB, an indication field may be added in the reserved bits to indicate the HARQ association indication.

实例7Example 7

一种NR终端的第一控制信息的格式4可以如下所示：A format 4 of the first control information of an NR terminal may be as follows:

ⅵ)PSFCH overhead指示域；比如，用于指示PSFCH overhead相关信息。ⅵ) PSFCH overhead indication field; for example, used to indicate PSFCH overhead related information.

ⅶ)目的ID指示域；比如，用于指示接收UE的ID。ⅶ) Destination ID indication field; for example, it is used to indicate the ID of the receiving UE.

此时，相对于实例5，第一控制信息还包括目的ID指示，用于接收终端根据目的ID信息判断数据是否是发给自己的，从而在不是发给自己时，实现检测(sensing)不需要再检测下一级控制信息。进一步的，如果预留比特数足够，在上述基础上，还可以发送源ID指示。At this time, with respect to Example 5, the first control information also includes a destination ID indication, which is used for the receiving terminal to judge whether the data is sent to itself according to the destination ID information, so that when it is not sent to itself, it is not necessary to realize the detection (sensing) Then detect the next level of control information. Further, if the number of reserved bits is sufficient, on the above basis, the source ID indication may also be sent.

实例8Example 8

一种NR终端的第一控制信息的格式5可以如下所示：A format 5 of the first control information of an NR terminal may be as follows:

ⅰ)第二控制信息的格式指示域；比如，用于指示可能存在的下一SCI即第二控制信息的格式。i) The format indication field of the second control information; for example, it is used to indicate the format of the second control information which may be the next SCI.

ⅱ)Beta_offset指示域；比如，用于指示确定第一共享信道上承载的控制信息的相关信息，比如计算调制符号数等信息的中间量。ii) Beta_offset indication field; for example, it is used to indicate relevant information for determining the control information carried on the first shared channel, such as calculating the intermediate amount of information such as the number of modulation symbols.

ⅲ)额外MCS指示域；比如，用于额外进行MCS指示。iii) Additional MCS indication field; eg, for additional MCS indication.

ⅳ)PSFCH overhead指示域；比如，用于指示PSFCH overhead相关信息。ⅳ) PSFCH overhead indication field; for example, it is used to indicate PSFCH overhead related information.

ⅴ)目的ID指示域；比如，用于指示接收UE的ID。v) Destination ID indication field; for example, it is used to indicate the ID of the receiving UE.

此时，相对于实例7，本实例考虑到了在NR重用LTE DMRS设计以及端口数为1时，不需要再指示DMRS相关信息。进一步的，如果预留比特数足够，在上述基础上，还可以发送源ID指示。At this time, compared with Example 7, this example considers that when NR reuses the LTE DMRS design and the number of ports is 1, it is not necessary to indicate DMRS related information. Further, if the number of reserved bits is sufficient, on the above basis, the source ID indication may also be sent.
