[0174] Figure 1A block diagram of a wireless communication system applicable to the embodiments of the present application is shown. The wireless communication system includes a terminal device (also referred to as a terminal) and a network device.

[0175] The terminal device involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). The wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA) and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, and a user device, but is not limited in the embodiments of the present application.

[0176] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long-term evolution (long term evolution, LTE) system, a 5G base station (the next Generation Node B, gNB) in the 5G network architecture (next generation system), or a home evolved Node B (Home evolved Node B, HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0177] The following first introduces the contents involved in the solution provided in the embodiment of the present application.

[0178] Regarding the process of using SL-PRS to complete the relative positioning between terminals, the specific process is as follows: Figure 2As shown in (schematic diagram of terminal 1 sending a direct link positioning reference signal to terminals 2 to 4 to complete its own positioning process), terminal 1 uses time-frequency resources to send SL-PRS to terminals 2 to 4 respectively. After receiving the SL-PRS, terminals 2 to 4 send the measurement results to terminal 1 to assist terminal 1 in completing the positioning solution.

[0179] In addition, specifically, SL-PRS may be transmitted in a dedicated resource pool or in a shared resource pool. Dedicated resource pool and shared resource pool are two types of resource pools that can be used for SL-PRS transmission. In a dedicated resource pool, only SL-PRS and its associated physical sidelink control channel (PSCCH) can be transmitted. In a shared resource pool, SL-PRS can be transmitted, as well as SL data that is not related to positioning, such as a physical sidelink shared channel (PSSCH) or a physical sidelink feedback channel (PSFCH). When SL-PRS is transmitted in a shared resource pool, PSSCH and SL-PRS are transmitted in the same time slot (PSSCH and SL-PRS may share some fields to indicate information). The receiving terminal needs to determine whether some information of the same type of SL-PRS resources is the same as some information of PSSCH and whether the same type of information is transmitted using the same field or different fields. Only in this way can the receiving terminal accurately receive SL-PRS and complete SL positioning. For example: Regarding the broadcast type information field in the sidelink control information (SCI), this information may be both the broadcast type of PSSCH and the broadcast type of SL-PRS, and the two may be carried by a common domain, so the terminal needs to know whether the broadcast type information of PSSCH and SL-PRS is the same and whether the same domain is used for transmission, so as to decode and obtain the broadcast type information of SL-PRS; in other words, the terminal needs to know whether the broadcast type information of the SL-PRS resource is the same as the broadcast type information of PSSCH, whether the two are indicated by a common domain in SCI, or by two separate domains in SCI. However, there is currently no relevant technical solution for how to send information to the terminal to indicate the SCI common domain of SL-PRS and PSSCH in the shared resource pool so that the terminal can obtain this information.

[0180] Based on the above, the embodiments of the present application provide an information transmission method, device and equipment to solve the problem that the terminal cannot accurately obtain the relevant information of SL-PRS transmission in the prior art. Among them, the method, device and equipment are based on the same application concept.

[0251] If bit N4 in the second indication information indicates that the two may be different (in this case, N4 can be used to indicate "independent indication" for the two, but is not limited to this), then it indicates that the reservation period of SL-PRS and the reservation period of PSSCH may be different.

[0252] 4. An independent field in a single SCI includes first information and second information of the same type (corresponding to the case where the fourth information includes the first information and the second information):

[0253] (1) A single SCI for a shared resource pool includes two fields indicating the same type (corresponding to the first field and the second field, the first field and the second field indicating the same type of information), the two fields respectively include first information and second information of the same type (corresponding to the first field being used to indicate the content included in the first information in the fourth information, and the second field being used to indicate the content included in the second information in the fourth information), and specifically satisfies at least one of the following:

[0257] A single SCI includes a field indicating a reservation period of the SL-PRS and another field indicating a reservation period of the PSSCH; wherein the reservation period here may also be referred to as reservation period information.

[0258] 5. The common domain in a single SCI contains the third information:

[0264] 6. Carrier of the first control information:

[0265] (1) The first information, the second information, the third information, the fourth information, the first indication information, and the second indication information are all carried by the first-level SCI, such as SCI format 1A;

[0266] (2) The first information, the second information, the third information, the fourth information, the first indication information, and the second indication information are all carried by the second-level SCI, such as SCI format 2D;

[0267] (3) The first information, the second information, the third information, the fourth information, the first indication information, and the second indication information are all carried by Radio Resource Control (RRC) signaling, such as Proximity Communication Port 5 (PC5) RRC signaling;

[0268] (4) The first information, the second information, the third information, the fourth information, the first indication information, and the second indication information are all carried by Sidelink Positioning Protocol (SLPP) signaling;

[0269] (5) The first information, the second information, the third information, the fourth information, the first indication information, and the second indication information are carried by the above multiple carriers in a mixed manner, such as the first information, the second information, the third information, and the fourth information are indicated by the second-level SCI, and the first indication information and the second indication information are indicated by SLPP signaling.

[0270] (1)-(6) under the above "carrier of the first control information" corresponds to the above-mentioned second target information being carried by the target carrier; wherein the second target information includes: at least one of the first information, the second information, the first indication information, the second indication information, the third information and the fourth information; the target carrier includes: at least one of the first-level SCI, the second-level SCI, the downlink control information DCI, the radio resource control RRC signaling and the direct link positioning protocol SLPP signaling.

[0271] The following is a specific example to illustrate this solution.

[0272] Example 1 (first information, second information, third information, fourth information):

[0273] This embodiment mainly involves: terminal A or base station sends first control information to terminal B, and the first control information contains at least one of the third information and the fourth information. Among them, the third information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period shared by SL-PRS and PSSCH; the fourth information contains the first information and the second information. The first information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period of SL-PRS. The second information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period of PSSCH. Subsequently, terminal B can receive the SL-PRS and / or PSSCH sent by terminal A based on the first control information. Specifically:

[0274] (1) The first information refers to the relevant information of the SL-PRS, including at least one of the following information: the broadcast type of the SL-PRS, the destination identification number of the SL-PRS, the priority of the SL-PRS, and the reservation period of the SL-PRS.

[0275] (2) The second information refers to PSSCH related information, including at least one of the following information: PSSCH broadcast type, PSSCH destination identification number, PSSCH priority, PSSCH reservation period, etc.

[0276] (3) The third information refers to the related information shared by SL-PRS and PSSCH, including at least one of the following information: the broadcast type of SL-PRS and PSSCH, the destination identification number of SL-PRS and PSSCH, the priority of SL-PRS and PSSCH, the reservation period of SL-PRS and PSSCH, etc.

[0277] (4) The fourth information includes the first information and the second information, and the fourth information refers to the collection of the first information and the second information.

[0278] (5) The first information of SL-PRS in the fourth information may be different from the second information of the same type of PSSCH, while the information of the same type shared by SL-PRS and PSSCH in the third information is the same.

[0279] Specifically, the broadcast type may refer to whether the SL-PRS or PSSCH is sent in unicast (sent to only one designated receiving terminal), multicast (sent to multiple designated receiving terminals) or broadcast (sent to all non-designated receiving terminals that can receive SL-PRS and PSSCH). The destination identification number may refer to the receiving terminal identification number of the SL-PRS or PSSCH. The priority may refer to the data packet transmission priority of the SL-PRS or PSSCH. The reservation period may refer to the period value of the resource reservation of the SL-PRS or PSSCH. The broadcast types of SL-PRS and PSSCH may be the same or different. The same is true for other information. Such as Figure 5 As shown in (Schematic diagram of SL-PRS and PSSCH in a shared resource pool), in a shared resource pool, SL-PRS and PSSCH are sent in a time slot using time division multiplexing; SL-PRS is sent in a broadcast mode to all terminals that can receive it, including terminal B; and PSSCH is sent in a unicast mode only to terminal B. AGC stands for Automatic Gain Control, GP stands for Guard Period, OFDM stands for Orthogonal Frequency Division Multiplexing, and PRB stands for Physical Resource Block.

[0280] In addition, the first information refers to the relevant information of SL-PRS, including at least one of the following information: the broadcast type of SL-PRS, the destination identification number of SL-PRS, the priority of SL-PRS, the reservation period of SL-PRS, etc. The second information refers to the relevant information of PSSCH, including at least one of the following information: the broadcast type of PSSCH, the destination identification number of PSSCH, the priority of PSSCH, the reservation period of PSSCH, etc. Among them, the first information of SL-PRS may be different from the second information of the same type of PSSCH, for example: the broadcast type of SL-PRS may be different from the broadcast type of PSSCH, or they may be the same, and other types of information are also similar; therefore, it is divided into the first information and the second information to represent, and the two are independent of each other. The fourth information includes the first information and the second information, and the fourth information refers to the collection of the first information and the second information. That is to say, the fourth information must include both the first information and the second information, that is, it includes relevant information of SL-PRS and relevant information of PSSCH, and the two are generally of the same type. For example: the fourth information includes the destination identification number of SL-PRS and the destination identification number of PSSCH (but the two are not necessarily the same).

[0281] The third information refers to the related information shared by SL-PRS and PSSCH, including at least one of the following information: the broadcast type of SL-PRS and PSSCH, the destination identification number of SL-PRS and PSSCH, the priority of SL-PRS and PSSCH, the reservation period of SL-PRS and PSSCH, etc. The difference between the third information and the first information or the second information is that the third information is the information shared by SL-PRS and PSSCH, that is, the corresponding information content of the same type of SL-PRS and PSSCH is the same, for example, the priority of SL-PRS and PSSCH in the third information indicates both the priority of SL-PRS and the priority of PSSCH, and the priority of SL-PRS and PSSCH is the same; if the two are different, the third information cannot be used to represent them.

[0282] From the above, by adopting the multiple information indication method of this embodiment, the terminal can determine the broadcast type and other information of SL-PRS and PSSCH according to the first information, the second information, the third information, the fourth information and other information, so that the terminal can complete the reception and decoding of SL-PRS according to the above information, and complete the direct link positioning according to SL-PRS.

[0283] Embodiment 2 (first indication information):

[0284] The scheme of this embodiment mainly involves: terminal A or base station sends first control information to terminal B, and the first control information contains first indication information. The first indication information indicates whether all first information of the same type are the same as the second information. The first information refers to at least one item of information such as the broadcast type, destination identification number, priority, and reservation period of SL-PRS. The second information refers to at least one item of information such as the broadcast type, destination identification number, priority, and reservation period of PSSCH. Subsequently, terminal B can receive SL-PRS and / or PSSCH sent by terminal A according to the first control information.

[0285] Specifically, the first instruction information is introduced as follows:

[0286] (1) The first indication information indicates whether all first information and second information of the same type are the same; the first indication information can be represented by 1 bit; in some embodiments, it can also be represented by multiple bits. Those skilled in the art can determine the number of bits according to actual circumstances, and this is not limited.

[0287] (2) If the first indication information indicates that the two (i.e., all first information and second information of the same type) are the same, then the following conditions are all satisfied:

[0288] The broadcast type in the first message is the same as the broadcast type in the second message;

[0289] The destination identification number in the first message is the same as the destination identification number in the second message;

[0290] The priority in the first message is the same as the priority in the second message;

[0291] The reservation period in the first information is the same as the reservation period in the second information.

[0292] (3) If the first indication information indicates that the two may be different, then at least one of the following conditions is met:

[0293] The broadcast type in the first message may be different from the broadcast type in the second message;

[0294] The destination identification number in the first message and the destination identification number in the second message may be different;

[0295] The priority in the first message may be different from the priority in the second message;

[0296] The reservation period in the first information may be different from the reservation period in the second information.

[0297] More specifically, Figure 6As shown (the first indication information indicates that the first information is the same as the second information), the first indication information indicates that all first information and second information of the same type are the same, that is:

[0298] The broadcast type in the first information and the broadcast type in the second information are both unicast;

[0299] The destination identification number in the first message and the destination identification number in the second message are both 56;

[0300] The priority in the first information and the priority in the second information are both 1;

[0301] The reservation period in the first information and the reservation period in the second information are both 1000 ms.

[0302] like Figure 7 As shown (the first indication information indicates that the first information and the second information may be different), the first indication information indicates that all the first information and the second information of the same type (at least one of them) may be different, that is:

[0303] The broadcast type in the first information is broadcast, and the broadcast type in the second information is unicast;

[0304] The destination identification number in the first message is none, and the destination identification number in the second message is 56;

[0305] The priority in the first information and the priority in the second information are both 1;

[0306] The reservation period in the first information and the reservation period in the second information are both 1000 ms.

[0307] From the above, by adopting the indication method of the first indication information of the present embodiment, the terminal can determine whether the broadcast type and other information of SL-PRS and PSSCH are the same according to the first indication information, and then be used to assist the terminal in determining the broadcast type and other information of SL-PRS and PSSCH, so that the terminal can complete the reception and decoding of SL-PRS according to the first control information, and complete the direct link positioning according to SL-PRS.

[0308] Embodiment 3 (second indication information):

[0309] The scheme of this embodiment mainly involves: terminal A or base station sends first control information to terminal B, and the first control information contains second indication information. The second indication information respectively indicates whether the first information and the second information of the same type are the same. The first information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period of SL-PRS. The second information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period of PSSCH. Subsequently, terminal B can receive SL-PRS and / or PSSCH sent by terminal A according to the first control information.

[0310] Specifically, the second instruction information is introduced as follows:

[0311] (1) The second indication information indicates whether the first information and the second information of the same type are the same.

[0312] (2) The second indication information is represented by using N bits (N is a positive integer greater than 1).

[0313] (3) Bit N1 in the second indication information is used to indicate whether the broadcast type of the SL-PRS is the same as the broadcast type of the PSSCH:

[0314] If bit N1 in the second indication information indicates that the two are the same, it means that the broadcast type of SL-PRS is the same as the broadcast type of PSSCH:

[0315] If the bit N1 in the second indication information indicates that the two may be different, it means that the broadcast type of SL-PRS and the broadcast type of PSSCH may be different.

[0316] (4) Bit N2 in the second indication information is used to indicate whether the destination identification number of the SL-PRS is the same as the destination identification number of the PSSCH:

[0317] If bit N2 in the second indication information indicates that the two are the same, it means that the destination identification number of the SL-PRS is the same as the destination identification number of the PSSCH:

[0318] If bit N2 in the second indication information indicates that the two may be different, it means that the destination identification number of the SL-PRS may be different from the destination identification number of the PSSCH.

[0319] (5) Bit N3 in the second indication information is used to indicate whether the priority of the SL-PRS is the same as the priority of the PSSCH:

[0320] If bit N3 in the second indication information indicates that the two are the same, it means that the priority of SL-PRS is the same as the priority of PSSCH:

[0321] If bit N3 in the second indication information indicates that the two may be different, it means that the priority of SL-PRS may be different from the priority of PSSCH.

[0322] (6) Bit N4 in the second indication information is used to indicate whether the reservation period of the SL-PRS is the same as the reservation period of the PSSCH:

[0323] If bit N4 in the second indication information indicates that the two are the same, it means that the reservation period of SL-PRS is the same as the reservation period of PSSCH:

[0324] If bit N4 in the second indication information indicates that the two may be different, it means that the reservation period of SL-PRS and the reservation period of PSSCH may be different.

[0325] More specifically, Figure 8 As shown in (Scheme of the second indication information), four bits N1 to N4 can be used to indicate whether the first information and the second information of the same type are the same, that is, whether the relevant information of the SL-PRS is the same as the relevant information of the PSSCH of the same type. Among them, N1 corresponds to the broadcast type, N2 corresponds to the destination identification number, N3 corresponds to the priority, and N4 corresponds to the reservation period. Assuming that N1 to N4 = 0, it means that the two are the same, and N1 to N4 = 1, it means that the two may be different; for example, Figure 8 In N1=1, it means that the transmission type of SL-PRS may be different from that of PSSCH, that is, the transmission type of SL-PRS is broadcast, while the transmission type of PSSCH is unicast. Figure 8 In the figure, N4=1, indicating that the reservation period of SL-PRS and the reservation period of PSSCH may be different, but in the embodiment, the reservation periods of the two are the same, that is, the reservation periods of SL-PRS and PSSCH are both 1000ms.

[0326] From the above, by adopting the indication method of the second indication information of the present embodiment, the terminal can independently determine whether the broadcast type, destination identification number and other information of the SL-PRS and PSSCH are the same according to the second indication information, and then use it to assist the terminal in determining the broadcast type, destination identification number and other information of the SL-PRS and PSSCH, so that the terminal can complete the reception and decoding of the SL-PRS according to the first control information, and complete the direct link positioning according to the SL-PRS.

[0327] Example 4 (independent domain in a single SCI):

[0328] The scheme of this embodiment mainly involves: terminal A or base station sends first control information to terminal B, and the first control information contains fourth information. The fourth information includes the first information and the second information. The first information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period of SL-PRS. The second information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period of PSSCH. Subsequently, terminal B can receive SL-PRS and / or PSSCH sent by terminal A according to the first control information.

[0329] Specifically, the fourth information is carried in the shared resource pool in the form of a "field", where a "field" refers to an information indication bit set composed of at least one bit, as shown below:

[0330] Assuming that the first control information is SCI, a single SCI for a shared resource pool includes two fields indicating the same type, and the two fields respectively include first information and second information of the same type, specifically satisfying at least one of the following:

[0331] A single SCI includes a field indicating the broadcast type information of the SL-PRS and another field indicating the broadcast type information of the PSSCH;

[0332] A single SCI includes a field indicating the destination identification number information of the SL-PRS and another field indicating the destination identification number information of the PSSCH;

[0333] A single SCI includes a field indicating the priority information of the SL-PRS and another field indicating the priority information of the PSSCH;

[0334] A single SCI includes a field indicating the reservation period information of the SL-PRS and another field indicating the reservation period information of the PSSCH.

[0335] Specifically, Fig. 9 As shown in (Schematic diagram of two independent domains in a single SCI), the overall diagram shows the content contained in a single SCI. Each dotted square in the figure represents a domain in a single SCI. The figure shows 6 domains, and the SCI may also contain other domains.

[0336] Among these 6 fields, field 1-1 indicates that the broadcast type information of SL-PRS is broadcast; corresponding to this field, field 2-1 indicates that the broadcast type information of PSSCH is unicast. Similarly, field 1-2 indicates that the destination identification number information of SL-PRS is none; corresponding to this field, field 2-2 indicates that the destination identification number information of PSSCH is 56. Field 1-3 is a field used to indicate other information of SL-PRS, and field 2-3 is a field used to indicate other information of PSSCH.

[0337] From the above, by adopting the indication method of independent domains in a single SCI of the present embodiment, the terminal can independently determine the broadcast type, destination identification number and other information content of the SL-PRS and PSSCH according to these domain information, and then use it to assist the terminal in determining the broadcast type, destination identification number and other information of the SL-PRS and PSSCH, so that the terminal can complete the reception and decoding of the SL-PRS according to these domain information, and complete the direct link positioning based on the SL-PRS.

[0338] Example 5 (common domain in a single SCI):

[0339] The scheme of this embodiment mainly involves: terminal A or base station sends first control information to terminal B, and the first control information contains third information. The third information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period shared by SL-PRS and PSSCH. The first information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period of SL-PRS. The second information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period of PSSCH. Subsequently, terminal B can receive SL-PRS and / or PSSCH sent by terminal A according to the first control information.

[0340] Specifically, the third information is carried in the shared resource pool in the form of a "field", where a "field" refers to an information indication bit set composed of at least one bit, as shown below:

[0341] Assume that the first control information is SCI, and a single SCI for a shared resource pool includes a field, and the field includes third information, which specifically satisfies at least one of the following:

[0342] A single SCI contains a common field, which indicates the broadcast type information of SL-PRS and the broadcast type information of PSSCH;

[0343] A single SCI contains a common field that indicates both the destination identification information of the SL-PRS and the destination identification information of the PSSCH;

[0344] A single SCI contains a common field that indicates both the SL-PRS priority information and the PSSCH priority information;

[0345] A single SCI includes a common field, which indicates both the reservation period information of the SL-PRS and the reservation period information of the PSSCH.

[0346] Specifically, Fig.10 As shown in (Schematic diagram of common domains in a single SCI), the overall diagram shows the content contained in a single SCI. Each dotted square in the diagram represents a domain in a single SCI. The diagram shows 4 domains, and the SCI may also contain other domains.

[0347] Among these four fields, field 1 is a common field, indicating that the broadcast type information of SL-PRS and the broadcast type information of PSSCH are unicast. Similarly, field 2 is also a common field, indicating that the destination identification number information of SL-PRS and the destination identification number information of PSSCH are 56. Fields 1-3 are used to indicate other information of SL-PRS, and fields 2-3 are used to indicate other information of PSSCH.

[0348] From the above, by adopting the method of indicating the common domain in a single SCI of the present embodiment, the terminal can determine the broadcast type, destination identification number and other information content shared by the SL-PRS and PSSCH based on these domain information, and then use it to assist the terminal in determining the broadcast type, destination identification number and other information shared by the SL-PRS and PSSCH, so that the terminal can complete the reception and decoding of the SL-PRS according to these domain information, and complete the direct link positioning based on the SL-PRS.

[0349] Embodiment 6 (carrier of the first control information):

[0350] The scheme of this embodiment mainly involves: terminal A or base station sends first control information to terminal B, and the first control information contains at least one of first indication information, second indication information, third information and fourth information. The first indication information indicates whether all first information of the same type are the same as the second information. The second indication information respectively indicates whether the first information of the same type is the same as the second information. The first information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period of SL-PRS. The second information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period of PSSCH. The third information refers to at least one information such as the broadcast type, destination identification number, priority, and reservation period shared by SL-PRS and PSSCH. The fourth information contains the first information and the second information. Subsequent terminal B can receive SL-PRS and / or PSSCH sent by terminal A according to the first control information.

[0351] Specifically, the carrier of the first control information is introduced as follows:

[0352] (1) The first information, the second information, the third information, the fourth information, the first indication information, and the second indication information are all carried by the first-level SCI, such as SCI format 1A;

[0353] (2) The first information, the second information, the third information, the fourth information, the first indication information, and the second indication information are all carried by the second-level SCI, such as SCI format 2D;

[0354] (3) The first information, the second information, the third information, the fourth information, the first indication information, and the second indication information are all carried by RRC signaling, such as PC5 RRC signaling;

[0355] (4) The first information, the second information, the third information, the fourth information, the first indication information, and the second indication information are all carried by SLPP signaling;

[0356] (5) The first information, the second information, the third information, the fourth information, the first indication information, and the second indication information are carried by the above multiple carriers in a mixed manner, such as the first information, the second information, the third information, and the fourth information are indicated by the second-level SCI, and the first indication information and the second indication information are indicated by SLPP signaling.

[0357] More specifically, Fig.11As shown in (schematic diagram of sending the first control information), terminal A sends the first control information to terminal B; if the first control information is carried by SCI, since SCI is directly carried through the physical layer channel, the latency is low, but the physical layer signaling overhead is high; if the first control information is carried by RRC or SLPP high-level signaling, the physical layer signaling will not be occupied, but the latency is high; of course, the first control information can also be carried by a mixture of the above multiple carriers, such as the first indication information in the first control information is indicated by the first-level SCI, the second indication information in the first control information is indicated by PC5 RRC signaling, and the third information and the fourth information in the first control information are carried by SLPP signaling. This carrying method can support the balance between physical layer signaling overhead and latency.

[0358] From the above, by adopting the first control information carrying scheme of this embodiment, the terminal can select a suitable first control information carrying method based on a comprehensive consideration of the physical layer signaling overhead and delay; thereby, the terminal can better send or receive SL-PRS and complete direct link positioning according to the first control information; while meeting the requirements of physical layer signaling overhead and delay.

[0359] In summary, this scheme proposes a method for indicating the SCI common domain of SL-PRS and PSSCH in a shared resource pool, including: terminal A or a base station sends a first control information to terminal B, wherein the first control information contains at least one of the first indication information, the second indication information, the third information and the fourth information, and the information is related to whether SL-PRS and PSSCH use the same or different broadcast types. Subsequently, terminal B can determine the broadcast type of SL-PRS and PSSCH in the shared resource pool according to the first control information, so that the terminal can complete the reception and decoding of SL-PRS according to this information, and complete the direct link positioning according to SL-PRS.

[0360] The embodiment of the present application also provides an information transmission device, the information transmission device is a first device, such as Fig.12 As shown, it includes a memory 121, a transceiver 122, and a processor 123:
