Description

Information transmission method, device and equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on August 10, 2023, with application number 202311004061.0 and application name “A method, device and apparatus for information transmission,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to an information transmission method, apparatus, and device. Background Art

[0003] In New Radio Access (NR) air interface positioning technology, downlink positioning reference signals and uplink positioning reference signals are defined in the air interface between the base station and the terminal to complete terminal positioning based on the downlink or uplink positioning reference signals. To meet the requirements of relative positioning between terminals, that is, direct link positioning, the sidelink positioning reference signal (SL-PRS) is also introduced. This allows terminals to complete the relative positioning process between terminals directly using the SL-PRS without relying on the downlink positioning reference signal or the uplink positioning reference signal.

[0004] However, in related technologies, a terminal cannot determine various information of the SL-PRS transmission to be received, resulting in an inability to complete the reception and decoding of the SL-PRS, and further an inability to complete the direct link positioning according to the SL-PRS.

[0176] Figure 1 shows a block diagram of a wireless communication system to which the embodiments of the present disclosure may be applied. The wireless communication system includes a terminal device (also referred to as a terminal) and a network device.

[0177] The terminal device involved in the embodiments of the present disclosure may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device 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 User Equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), 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, or a user device, but is not limited in the embodiments of the present disclosure.

Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or may be named by another name. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting 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 disclosure may be a base transceiver station (BTS) in the Global System for Mobile communications (GSM) or code division multiple access (CDMA), a network device (NodeB) in wide-band code division multiple access (WCDMA), an evolutionary Node B (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the next generation system, a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of the present disclosure.

[0179] The following first introduces the contents involved in the solution provided by the embodiment of the present disclosure.

[0180] Regarding the process of using SL-PRS to complete the relative positioning between terminals, it can be specifically shown in Figure 2 (a schematic diagram of terminal 1 sending a direct link positioning reference signal to terminals 2 to 4 to complete its own positioning process), wherein 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.

[0181] In addition, specifically, SL-PRS may be transmitted in a dedicated resource pool or in a shared resource pool. Dedicated resource pools and shared resource pools 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, both SL-PRS and SL data unrelated to positioning can be transmitted, such as the physical sidelink shared channel (PSSCH) or the 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 these same types of information are 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 the PSSCH and the broadcast type of the SL-PRS. The two may be carried by a common field. Therefore, the terminal needs to know whether the broadcast type information of the PSSCH and SL-PRS is the same and whether the same field is used for transmission in order to decode and obtain the broadcast type information of the 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 the PSSCH, and whether the two are indicated by a common field in the SCI or by two separate fields in the SCI. However, there is currently no relevant technical solution for how to send information indicating the SCI common field of the SL-PRS and PSSCH in the shared resource pool to the terminal so that the terminal can obtain this information.

[0182] Based on the foregoing, embodiments of the present disclosure provide an information transmission method, apparatus, and device to address the related art issue of a terminal being unable to accurately obtain information related to SL-PRS transmission.

[0253] 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" of 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.

[0254] 4. An independent field in a single SCI contains first information and second information of the same type (corresponding to the case where the fourth information contains the first information and the second information):

[0255] (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 including first information and second information of the same type (corresponding to the first field indicating the content of the first information in the fourth information, and the second field indicating the content of the second information in the fourth information), specifically meeting at least one of the following conditions:

[0256] A single SCI includes a field indicating the broadcast type of the SL-PRS and another field indicating the broadcast type of the PSSCH; wherein the broadcast type here may also be referred to as broadcast type information;

[0258] A single SCI includes a field indicating the priority of the SL-PRS and another field indicating the priority of the PSSCH; wherein the priority here can also be referred to as priority information;

[0259] A single SCI includes a field indicating the reservation period of the SL-PRS and another field indicating the reservation period of the PSSCH; wherein the reservation period here may also be referred to as reservation period information.

[0260] 5. The common domain in a single SCI contains the third information:

[0261] (1) A single SCI for a shared resource pool includes a field (corresponding to the common field) containing third information (corresponding to the common field for indicating the content of the third information), specifically satisfying at least one of the following:

[0262] A single SCI contains a common field that indicates both the SL-PRS broadcast type and the PSSCH broadcast type. The broadcast type here may also be referred to as broadcast type information.

[0263] A single SCI contains a common field that indicates both the destination identification number of the SL-PRS and the destination identification number of the PSSCH; the destination identification number here may also be referred to as destination identification number information;

[0264] A single SCI contains a common field that indicates the priority of the SL-PRS and the priority of the PSSCH. The priority here can also be called priority information.

[0265] A single SCI includes a common field, which indicates the reservation period of the SL-PRS and the reservation period of the PSSCH. The reservation period here may also be referred to as reservation period information.

[0266] 6. Carrier of the first control information:

[0267] (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;

[0268] (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;

[0269] (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;

[0270] (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;

[0271] (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 a mixed combination of the above multiple carriers. For example, 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.

[0272] (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.

[0273] The following is a specific example to illustrate this solution.

[0274] Example 1 (first information, second information, third information, fourth information):

[0275] The solution of this embodiment mainly involves: terminal A or the base station sends the 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:

[0276] (1) The first information refers to the relevant information of the SL-PRS, including at least one of the following information: the cast type of the SL-PRS, the destination ID of the SL-PRS, the priority of the SL-PRS, and the reservation period of the SL-PRS.

[0277] (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.

[0278] (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.

[0279] (4) The fourth information includes the first information and the second information, and the fourth information refers to the combination of the first information and the second information.

[0280] (5) The first information of the 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 the SL-PRS and PSSCH in the third information is the same.

[0281] Specifically, the transmission type may refer to whether the SL-PRS or PSSCH is transmitted using unicast (sent only to one designated receiving terminal), multicast (sent to multiple designated receiving terminals), or broadcast (sent to all non-designated receiving terminals that can receive the SL-PRS and PSSCH). The destination identifier may refer to the receiving terminal identifier of the SL-PRS or PSSCH. The priority may refer to the packet transmission priority of the SL-PRS or PSSCH. The reservation period may refer to the period value of the resource reservation for the SL-PRS or PSSCH. The transmission types of the SL-PRS and PSSCH may be the same or different. Other information is similar. As shown in Figure 5 (Schematic diagram of SL-PRS and PSSCH in a shared resource pool), in the shared resource pool, the SL-PRS and PSSCH are transmitted using time division multiplexing in a time slot; the SL-PRS is transmitted using broadcast to all terminals that can receive it, including terminal B; and the PSSCH is transmitted using unicast 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.

[0282] Furthermore, the first information refers to information related to the SL-PRS, including at least one of the following: the SL-PRS transmission type, the SL-PRS destination identifier, the SL-PRS priority, and the SL-PRS reservation period. The second information refers to information related to the PSSCH, including at least one of the following: the PSSCH transmission type, the PSSCH destination identifier, the PSSCH priority, and the PSSCH reservation period. The first information of the SL-PRS and the second information of the same type for the PSSCH may be different. For example, the SL-PRS transmission type and the PSSCH transmission type may be different or the same. Other types of information are also similar. Therefore, they are presented separately as the first and second information, which are independent of each other. The fourth information includes the first and second information and refers to the combination of the first and second information. That is to say, the fourth information must contain both the first information and the second information, that is, it contains relevant information of SL-PRS and relevant information of PSSCH, and the two are generally of the same type. For example: the fourth information contains the destination identification number of SL-PRS and the destination identification number of PSSCH (but the two are not necessarily the same).

[0283] 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 are the same; if the two are different, the third information cannot be used to represent them.

[0284] From the above, using the multiple information indication method of this embodiment, the terminal can determine the broadcast type and other information of SL-PRS and PSSCH based on the first information, second information, third information, fourth information, etc., so that the terminal can complete the reception and decoding of SL-PRS according to the above information, and complete the direct link positioning based on SL-PRS.

[0285] Example 2 (first indication information):

[0286] This embodiment primarily involves: Terminal A or a base station sending first control information to Terminal B, the first control information containing first indication information. The first indication information indicates whether all first information of the same type is identical to 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 the 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 the PSSCH. Terminal B can subsequently receive the SL-PRS and / or PSSCH sent by Terminal A based on the first control information.

[0287] Specifically, the first instruction information is described as follows:

[0288] (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 based on actual circumstances, and this is not limited.

[0289] (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 met:

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

[0291] The destination identification number in the first message is the same as the destination identification number in the second message;

[0292] The priority in the first message is the same as the priority in the second message;

[0293] The reservation period in the first information is the same as the reservation period in the second information.

[0294] (3) If the first indication information indicates that the two may be different, then at least one of the following conditions is met:

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

[0296] The destination identification number in the first message and the destination identification number in the second message may be different;

[0297] The priority in the first message may be different from the priority in the second message;

[0298] The reservation period in the first information and the reservation period in the second information may be different.

[0299] More specifically, as shown in FIG6 (the first indication information indicates that the first information and the second information are the same), the first indication information indicates that all first information and second information of the same type are the same, that is:

[0300] The broadcast type in the first message and the broadcast type in the second message are both unicast;

[0301] The destination identification number in the first message and the destination identification number in the second message are both 56;

[0302] The priority in the first message and the priority in the second message are both 1;

[0303] The reservation period in the first message and the reservation period in the second message are both 1000 ms.

[0304] As shown in FIG7 (the first indication information indicates that the first information and the second information may be different), the first indication information indicates that all first information and second information of the same type (at least one of them) may be different, that is:

[0305] The broadcast type in the first information is broadcast, and the broadcast type in the second information is unicast;

[0306] The destination identification number in the first message is none, and the destination identification number in the second message is 56;

[0307] The priority in the first message and the priority in the second message are both 1;

[0308] The reservation period in the first message and the reservation period in the second message are both 1000 ms.

[0309] From the above, using the indication method of the first indication information of this embodiment, the terminal can determine whether the broadcast type and other information of SL-PRS and PSSCH are the same based on the first indication information, and then use it 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 based on SL-PRS.

[0310] Example 3 (second indication information):

[0311] This embodiment primarily involves: Terminal A or a base station sending first control information to Terminal B, the first control information containing second indication information. The second indication information indicates whether the first information and second information of the same type are identical. The first information refers to at least one item of information, such as the broadcast type, destination identification number, priority, and reservation period of the 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 the PSSCH. Terminal B can subsequently receive the SL-PRS and / or PSSCH sent by Terminal A based on the first control information.

[0312] Specifically, the second instruction information is described as follows:

[0313] (1) The second indication information indicates whether the first information and the second information of the same type are the same.

[0314] (2) The second indication information is represented using N bits (N is a positive integer greater than 1).

[0315] (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:

[0316] 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:

[0317] If the bit N1 in the second indication information indicates that the two may be different, it means that the broadcast type of the SL-PRS may be different from the broadcast type of the PSSCH.

[0318] (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:

[0319] 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:

[0320] 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.

[0321] (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:

[0322] 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:

[0323] 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.

[0324] (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:

[0325] 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:

[0326] 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.

[0327] More specifically, as shown in FIG8 (a schematic diagram 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 indicates that the two are the same, while N1 to N4 = 1, it indicates that the two may be different. For example, in FIG8, N1 = 1 indicates that the broadcast type of the SL-PRS and the broadcast type of the PSSCH may be different, that is, the broadcast type of the SL-PRS is broadcast, while the broadcast type of the PSSCH is unicast. For another example, in FIG8, N4 = 1 indicates that the reservation period of the SL-PRS and the reservation period of the PSSCH may be different. However, in this embodiment, the reservation periods of the two are the same, that is, the reservation periods of the SL-PRS and the PSSCH are both 1000ms.

[0328] From the above, using the indication method of the second indication information of this 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 based on 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 based on the SL-PRS.

[0329] Example 4 (independent domain in a single SCI):

[0330] This embodiment primarily involves: Terminal A or a base station sending first control information to Terminal B, the first control information containing fourth information. The fourth information includes the first information and the second information. The first information is at least one item of information, such as the SL-PRS broadcast type, destination identification number, priority, and reservation period. The second information is at least one item of information, such as the PSSCH broadcast type, destination identification number, priority, and reservation period. Terminal B can subsequently receive the SL-PRS and / or PSSCH sent by Terminal A based on the first control information.

[0331] 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 consisting of at least one bit, as shown below:

[0332] 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:

[0333] 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;

[0334] 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;

[0335] A single SCI includes a field indicating the priority information of the SL-PRS and another field indicating the priority information of the PSSCH;

[0336] 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.

[0337] Specifically, as shown in Figure 9 (Schematic diagram of two independent domains in a single SCI), the overall diagram represents the content contained in a single SCI. Each dotted square in the figure represents a domain in a single SCI. The figure shows six domains, and the SCI may also contain other domains.

[0338] Of these six fields, field 1-1 indicates that the SL-PRS transmission type is broadcast; correspondingly, field 2-1 indicates that the PSSCH transmission type is unicast. Similarly, field 1-2 indicates that the SL-PRS destination identification number is none; correspondingly, field 2-2 indicates that the PSSCH destination identification number is 56. Fields 1-3 are used to indicate other SL-PRS information, and fields 2-3 are used to indicate other PSSCH information.

[0339] From the above, by adopting the indication method of independent fields in a single SCI of this embodiment, the terminal can independently determine the broadcast type, destination identification number and other information content of the SL-PRS and PSSCH based on these field 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 field information, and complete the direct link positioning based on the SL-PRS.

[0340] Example 5 (common domain in a single SCI):

[0341] This embodiment primarily involves: Terminal A or a base station sends first control information to Terminal B, where the first control information includes third information. The third information refers to at least one item of information shared by the SL-PRS and PSSCH, such as the broadcast type, destination identification number, priority, and reservation period. The first information refers to at least one item of information, such as the broadcast type, destination identification number, priority, and reservation period, of the 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 the PSSCH. Terminal B can subsequently receive the SL-PRS and / or PSSCH sent by Terminal A based on the first control information.

[0342] 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 consisting of at least one bit, as shown below:

[0343] Assume that the first control information is an SCI, and a single SCI for a shared resource pool includes a field, and the field includes third information, specifically satisfying at least one of the following:

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

[0345] 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.

[0346] A single SCI contains a common field that indicates both the SL-PRS priority information and the PSSCH priority information;

[0347] A single SCI contains a common field, which indicates both the reservation period information of the SL-PRS and the reservation period information of the PSSCH.

[0348] Specifically, as shown in Figure 10 (Schematic diagram of shared domains in a single SCI), the overall diagram represents the content contained in a single SCI. Each dotted square in the figure represents a domain in a single SCI. The figure shows four domains, and the SCI may also contain other domains.

[0349] Of these four fields, Field 1 is a common field that indicates both the SL-PRS and PSSCH broadcast types as unicast. Similarly, Field 2 is also a common field that indicates both the SL-PRS and PSSCH destination identification numbers as 56. Fields 1-3 are used to indicate other SL-PRS information, and Fields 2-3 are used to indicate other PSSCH information.

[0350] From the above, using the method of indicating the shared domain in a single SCI in this embodiment, the terminal can determine the broadcast type, destination identification number and other information content shared by the SL-PRS and PSSCH based on this domain information, which is then used 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 based on this domain information, and complete the direct link positioning based on the SL-PRS.

[0351] Example 6 (carrier of the first control information):

[0352] This embodiment mainly involves: Terminal A or a 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 and second information of the same type are the same. The second indication information separately indicates whether the first information and second information of the same type are the same. The first information refers to at least one item of information such as the broadcast type, destination identification number, priority, and reservation period of the 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 the PSSCH. The third information refers to at least one item of information such as the broadcast type, destination identification number, priority, and reservation period shared by the SL-PRS and PSSCH. The fourth information includes the first information and the second information. Subsequently, Terminal B can receive the SL-PRS and / or PSSCH sent by Terminal A based on the first control information.

[0353] Specifically, the carrier of the first control information is introduced as follows:

[0354] (1) The first information, second information, third information, fourth information, first indication information, and second indication information are all carried by the first-level SCI, such as SCI format 1A;

[0355] (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;

[0356] (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 PC5RRC signaling;

[0357] (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;

[0358] (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 a mixed combination of the above multiple carriers. For example, 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.

[0359] More specifically, as shown in Figure 11 (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-layer signaling, it will not occupy the physical layer signaling, 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 PC5RRC signaling, and the third information and 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.

[0360] 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.

[0361] In summary, this solution proposes a method for indicating the SCI shared domain of the SL-PRS and PSSCH in a shared resource pool, including: terminal A or a base station sends first control information to terminal B, where the first control information contains at least one of first indication information, second indication information, third information, and fourth information, which is related to information such as whether the SL-PRS and PSSCH use the same or different broadcast types. Subsequently, terminal B can determine information such as the broadcast type of the SL-PRS and PSSCH in the shared resource pool based on the first control information, so that the terminal can complete the reception and decoding of the SL-PRS based on this information, and complete the direct link positioning based on the SL-PRS.

[0362] The embodiment of the present disclosure further provides an information transmission device. The information transmission device is a first device, as shown in FIG12 , including a memory 121, a transceiver 122, and a processor 123.

[0363] The memory 121 is used to store computer programs; the transceiver 122 is used to send and receive data under the control of the processor 123; the processor 123 is used to read the computer program in the memory 121 and perform the following operations:

[0364] Sending first control information to the first terminal via the transceiver 122;

[0365] Wherein, the first device is a second terminal or a network device;

[0366] The first control information includes: at least one of the first indication information, the second indication information, the third information, and the fourth information;

[0367] The first indication information is used to indicate whether the content of the same type of information included in the first information and the second information is the same; the first information includes: at least one of 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; the second information includes: at least one of the broadcast type of the PSSCH, the destination identification number of the PSSCH, the priority of the PSSCH, and the reservation period of the PSSCH;

[0368] The second indication information is used to indicate whether the content of each piece of information of the same type included in the first information and the second information is the same;
