[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] In the existing sidelink transmission technology, the device-to-device communication mode is different from the traditional cellular system in which communication data is received or sent by the base station. Because of its higher spectrum efficiency and lower transmission delay, it is widely used in various scenarios. For example, in the 3rd Generation Partnership Project (3GPP) technology, two transmission modes are defined, including: Mode A and Mode B (such as Figure 1 Schematic diagram shown):

[0044] Mode A (such as Figure 1 (a) in the figure): The transmission resources of the terminal are allocated by the base station. The terminal sends data on the side link according to the resources allocated by the base station. The base station can allocate resources for a single transmission to the terminal, or can allocate resources for a semi-static transmission to the terminal.

[0045] Mode B (such as Figure 1 As shown in (b) in the figure): the vehicle terminal selects a resource in the resource pool for data transmission.

[0046] In 3GPP, the device-to-device communication (D2D) is divided into different stages for research:

[0047] 1. Proximity based Service (ProSe): In Rel-12 / 13, device-to-device communication is studied for ProSe scenarios, which are mainly aimed at public safety services. For example, in ProSe, by configuring the position of the resource pool in the time domain, the UE can transmit / receive data discontinuously on the sidelink, thereby achieving power saving.

[0048] 2. In vehicle-to-everything (V2X), since the vehicle system has a continuous power supply,

[0049] Power efficiency is not the main issue, but the delay of data transmission is the main issue, so the system design requires the terminal equipment to perform continuous transmission and reception.

[0050] In addition, based on LTE V2X, NR V2X is not limited to broadcast scenarios, but further expanded to unicast and multicast scenarios, and studies the application of V2X in these scenarios. For example, similar to LTE V2X, NR V2X will also define the above-mentioned two resource authorization modes, mode A and mode B (mode-1 / 2); further, the user may be in a mixed mode, that is, mode-1 can be used to obtain resources, and mode-2 can be used to obtain resources at the same time. The resource acquisition is indicated by the sidelink authorization, that is, the sidelink authorization indicates the time-frequency position of the corresponding resource. Different from LTEV2X, in addition to the HARQ retransmission initiated by the UE without feedback, NR V2X introduces feedback-based HARQ retransmission, which is not limited to unicast communication, but also includes multicast communication; similar to LTE V2X, in NR V2X, since the vehicle system has continuous power supply, power efficiency is not the main problem, but the delay of data transmission is the main problem, so the system design requires the terminal equipment to send and receive continuously.

[0051] 3. Wearable devices (FeD2D): In Rel-14, this scenario studies the scenario of wearable devices accessing the network through mobile phones, mainly for low mobile speed and low power access scenarios. In FeD2D, in the pre-research stage, 3GPP concluded that the base station can configure the DRX parameters of the remote terminal through a relay terminal, but because the subject has not entered the standardization stage, the specific details of how to configure DRX have not been concluded.

[0052] Based on the above discussion and application, regardless of the application scenario, the sidelink transmission technology has high requirements for continuous transmission and reception of terminal devices.

[0053] However, in the existing Media Access Control (MAC) protocol from user terminal to network, or from user terminal to user terminal relay, the processing of erroneous data is only to determine whether to discard the entire PDU data or sub-PDU data by judging whether the protocol data unit (PDU) in the received MAC contains a logical channel identifier (LCID).

[0054] In one application, when a MAC entity receives a MAC PDU on the SL-SCH, and the MAC PDU includes a reserved LCID value for unicast or multicast, or an unconfigured LCID value, for example, when the MAC layer message includes a header and a payload, and the payload includes 3 subPDUs, and one of the subPDUs includes a reserved LCID value, or an unconfigured LCID value, it is considered that erroneous data appears in the MAC message, and the subPDU is directly discarded.

[0055] In another application, when the MAC entity receives a MAC PDU containing a reserved LCID value for unicast on the SL-SCH, the MAC entity should discard the subPDU or the entire PDU received in the MAC PDU. For example, when the MAC layer message includes a header and a payload, and the payload includes 3 subPDUs, if one of the sub-PDUs includes an unconfigured LCID value, the subPDU is discarded; or, if one of the sub-PDUs includes a reserved LCID value, the entire PDU is discarded.

[0056] The above is the existing technology for handling erroneous data. Obviously, the above method does not handle the erroneous data situation about the source / destination ID in the MAC message header, which is easy to cause inaccurate data processing, thereby affecting the continuity of receiving or sending data, and failing to meet the high requirements and high standards for continuous sending and receiving of terminal devices in the side link transmission technology. In addition, the existing technology for handling erroneous data does not take into account the erroneous data situation of the adaptation layer ADAPT layer (on the radio link control (Radio Link Control, RLC) layer and the packet data convergence (Packet Data Convergence Protocol, PDCP) layer, resulting in an increased probability of errors in data transmission applied to the adaptation layer ADAPT, thereby affecting the continuity of receiving or sending data, and failing to meet the high requirements and high standards for continuous sending and receiving of terminal devices in the side link transmission technology.

[0057] Based on the above problems, the present application provides an information processing method, apparatus, computer equipment and storage medium. On the one hand, the source / destination ID in the MAC message header can be used to accurately process erroneous data and improve the continuity of data transmission. On the other hand, erroneous data processing in the adaptation layer ADAPT can also be implemented. While improving the continuity of data transmission, the applicability of the above method can also be improved. The following embodiments will specifically introduce the above method.

[0058] The information processing method provided in this application can be applied to Figure 2 In the application environment shown in the figure, the sending terminal 102 and the receiving terminal 104 are connected in communication, and the data transmission between the sending terminal 102 and the receiving terminal 104 is based on a communication protocol including 7 layers, such as Figure 2 The PC5-PHY layer, PC5-MAC layer, PC5-RLC layer, ADAPT layer, PC5-PDCP layer, PC5-SDAP layer, and IP layer in the transmission terminal 102 or the receiving terminal 104 can be, but not limited to, various personal computers, laptops, smart phones, tablet computers, and portable wearable devices. The transmission terminal 102 or the receiving terminal 104 can be a user terminal in the communication network or a relay terminal; the transmission terminal 102 or the receiving terminal 104 can also be various vehicle-mounted terminals or relay terminals in the Internet of Vehicles.

[0059] Those skilled in the art will understand that Figure 2 The structure shown in the figure is merely a block diagram of a partial structure related to the present application scheme, and does not constitute a limitation on the application environment to which the present application scheme is applied. The specific application environment may include more or fewer components than those shown in the figure, or combine certain components, or have a different component arrangement.

[0060] In one embodiment, Figure 3A As shown, an information processing method is provided, which is applied to Figure 2 The receiving terminal in is taken as an example to illustrate. Figure 3A As shown, the process includes the following steps:

[0061] S101, obtaining first information of a sending terminal, where the first information includes first identification information.

[0062] The sending terminal may be a remote UE, a relay UE or a network device (such as Figure 3B UE to network relay application scenario shown in FIG), it may also be a source UE or a relay UE in a UE to UE relay application scenario (such as Figure 3CThe first information may be a MAC message, and the first identification information may include a destination field in the first information, indicating a destination address of the sending terminal to send data. The first identification information may also include a source address in the first information, indicating an address of the sending terminal. Alternatively, the first identification information may also include a device identification of the sending terminal, a device identification of the receiving terminal, and the like, which is not limited in the embodiments of the present application. Optionally, the first identification information is carried in a MAC message header and / or a MAC sub-PDU of the first information. For example, the first identification information may include a destination ID / destination field in a MAC message header, etc.

[0063] In this embodiment, the receiving terminal may be a terminal that receives the communication information sent by the sending device and parses the first information from the communication information. Alternatively, the receiving terminal may directly receive the first information from the sending terminal and the receiving terminal may obtain the first identification information by parsing the first information. For example, when the MAC entity of the receiving terminal receives a MAC message on the SL-SCH, the receiving terminal may parse the MAC message to obtain the first information in the MAC message and then extract the first identification information from the first information. Figure 3D A schematic diagram of a header of a MAC message is provided, wherein the SRC information and / or DST information included in the header is first identification information. When a receiving terminal receives a MAC message including the header, the SRC information and / or DST information can be extracted from the header of the MAC message as the first identification information.

[0064] S102: Determine whether to discard data in the first information according to the first identification information and the second identification information of the receiving terminal.

[0065] The second identification information is some device identification, address identification, etc. configured by the receiving terminal. For example, the second identification information includes the source identification (source ID) configured by the receiving terminal, and the second identification information may also include the destination identification (destination ID) configured by the receiving terminal, etc. Optionally, the data in the first information includes the PDU in the first information, and may also include the sub-PDU (subPDU) in the first information. For example, the data in the first information includes MAC PDU or MAC sub-PDU (subPDU), that is, the data in the first information may be all the data in the first information, or may be part of the data. For example, when the receiving terminal receives several subPDUs, the data in the first information may be all the subPDUs, or may be one or more of the subPDUs.

[0066] In this embodiment, when the receiving terminal receives data from the sending terminal, for example, when the MAC entity of the receiving terminal receives a MAC message on the SL-SCH, in one scenario, the receiving terminal can determine whether the destination field in the received MAC message and the receiving terminal's own source ID match. If they match, it means that the receiving terminal can receive the data transmission of the sending terminal. Optionally, the receiving terminal can further determine whether to discard all or part of the data in the first information based on the configuration or assignment of the LCID in the received data; if they do not match, it means that the receiving terminal cannot receive the data transmission of the sending terminal. In this case, the receiving terminal directly discards all the data in the first information. In another scenario, after the receiving terminal determines whether the destination field in the received MAC message matches the receiving terminal's own sourceID, if the destination field in the received MAC message matches the receiving terminal's own source ID, it can further determine whether the source ID in the received MAC message matches the receiving terminal's destination field. If they match, it means that the receiving terminal can receive the data transmission of the sending terminal. In this case, the receiving terminal can further determine whether to discard all or part of the data in the first information based on the configuration or assignment of the LCID in the received data; if they do not match, it means that the receiving terminal cannot receive the data transmission of the sending terminal, or the received data is erroneous data. In this case, the receiving terminal does not perform the operation of receiving the data, or directly discards all the data in the first information. It should be noted that the determination of whether the destination field and the source ID match can be made by determining whether the destination field and the source ID are consistent, or by other methods.

[0067] It should be noted that when the above-mentioned discarding process is performed, the data in the first information is discarded, and the PDU in the first information can be specifically discarded, for example, the entire received PDU is discarded; or, the sub-PDU in the first information is discarded, for example, one received sub-PDU is discarded, and the remaining received sub-PDUs are retained.

[0068] It should also be noted that this is only used as an example in the embodiments of the present application and is not intended to limit the present embodiments.

[0069] The information processing method provided in the above embodiment obtains the first information including the first identification information, and determines whether to discard the data in the first information according to the first identification information and the second identification information of the receiving terminal. The method implements a method for processing error information in combination with the first identification information, and the first identification information can be the header information in the MAC message. Therefore, the present application provides a new method for processing error information based on MAC header information. Compared with the traditional method of processing error information only according to LCID, the accuracy of error information processing can be improved, thereby improving the continuity and efficiency of receiving data at the receiving terminal.

[0070] Above Figure 3A In the method described in Example S102, optionally, the first identification information includes the destination domain in the first information, and the second identification information includes the source ID configured for the receiving terminal. Then, when the receiving terminal determines whether the destination domain in the received first information matches the source identification ID, there is an application scenario, that is, the destination domain in the first information does not match the source ID configured for the receiving terminal. For example, the receiving terminal is UE1, and the destination domain in the first information does not match the source ID of UE1. In this case, the receiving terminal directly discards all data in the first information, that is, the receiving terminal receives data but discards the data, thereby avoiding the problem of erroneous data reception caused by the mismatch between the sending terminal and the receiving terminal, and improving the accuracy of data received by the receiving terminal.

[0071] When judging whether the destination domain in the first information does not match the source ID, a method for determining that the destination domain does not match the source ID is provided. The method includes: if the destination domain in the first information does not match the high data bit of the source ID configured by the receiving terminal, and / or if the destination domain in the first information does not match the low data bit of the source ID configured by the receiving terminal, then it is determined that the destination domain does not match the source identification ID.

[0072] The method described in this embodiment is exemplified. For example, the total length of the destination ID is 24 bits, of which the lower 8 bits are in the physical control channel and the upper 16 bits of the destination field are in the MAC message header. Based on this, when determining whether the destination field matches the source ID, if the lower 16 bits of the destination field and the source identification ID do not match (for example, are inconsistent), it is determined that the destination field and the source ID do not match; or, if the higher 16 bits of the destination field and the source identification ID do not match (for example, are inconsistent), it is determined that the destination field and the source ID do not match; or, if the lower 16 bits of the destination field and the source ID do not match, and the higher 16 bits of the destination field and the source ID do not match, it is determined that the destination field and the source ID do not match.

[0073] In practical applications, when the receiving terminal processes the received first information, the first information includes not only the first identification information but also the logical channel identification LCID. Thus, the receiving terminal can determine whether to discard the data in the first information by using the first identification information and the LCID included in the first information. Based on this, in one embodiment, an implementation method is provided when the receiving terminal performs the above step S102, such as Figure 4 As shown, the method specifically includes:

[0074] S103, determining whether to discard the data in the first information according to the first identification information, the LCID and the second identification information of the receiving terminal.

[0075] The first identification information includes the destination domain in the first information, and the second identification information includes the source ID configured by the receiving terminal.

[0076] When executing the above-mentioned step S103, it is possible to first determine whether the destination domain in the first information matches the source ID configured for the receiving terminal. The specific method for determining the match includes: if the destination domain in the first information matches the high data bit of the source ID configured for the receiving terminal; and / or, if the destination domain in the first information matches the low data bit of the source ID configured for the receiving terminal, then it is determined that the destination domain in the first information matches the source ID configured for the receiving terminal. For example, the total length of the destination ID is 24 bits, of which the lower 8 bits are in the physical control channel, and the upper 16 bits of the destination field are in the MAC message header. Based on this, when determining whether the destination field matches the source ID, if the destination field matches the lower 16 bits of the source ID (for example, they are consistent), then it is determined that the destination field matches the source ID; or, if the destination field matches the upper 16 bits of the source ID (for example, they are consistent), then it is determined that the destination field matches the source ID; or, if the destination field matches the lower 16 bits of the source ID, and the destination field also matches the upper 16 bits of the source ID, then it is determined that the destination field matches the source ID.

[0077] In actual applications, when the destination domain in the first information matches the source ID configured by the receiving terminal, there are three ways of processing the information in application scenarios. The following describes these three information processing methods:

[0078] The first application scenario is: if the destination domain in the first information matches the source ID configured by the receiving terminal, and the LCID is a specific LCID, a receiving operation is performed on the first information.

[0079] In this scenario, LCID is a specific LCID, for example, LCID is LCID-0 or LCID-1 used to transmit PC5-S. This scenario indicates that the sending terminal hopes to establish a connection with the local receiving terminal, and the local receiving terminal also needs to support reception, that is, LCID is the LCID negotiated by the sending terminal and the receiving terminal. Therefore, in this application scenario, the local receiving terminal (such as the local UE) performs the receiving operation of the relevant data, that is, the receiving operation of the first information, and does not perform any operation of discarding data.

[0080] The second application scenario is: if the destination domain in the first information matches the source ID configured by the receiving terminal, and the LCID is not a specific LCID, the data in the first information is discarded.

[0081] In this scenario, the LCID is an LCID other than a specific LCID. For example, the LCID is not LCID-0 or LCID-1 used to transmit PC5-S. This scenario indicates that the received LCID is not the LCID negotiated before between the sending terminal and the local receiving terminal. At this time, the data received by the receiving terminal is erroneous data. Therefore, in this application scenario, the local receiving terminal (such as the local UE) directly discards the data in the first information, for example, discards the PDU in the first information, or discards the subPDU in the received first information, that is, discards the data while receiving it.

[0082] The third application scenario is: if the destination domain in the first information matches the source ID configured for the receiving terminal, and the LCID is not the configured LCID, the data in the first information is discarded.

[0083] In this scenario, the LCID is not the configured LCID, indicating that the received LCID is not the LCID configured by negotiation between the sending terminal and the local receiving terminal. For example, the sending terminal and the local receiving terminal negotiate and use 0-4 bits to configure the LCID, but the received LCID is a 5-10 bits configured LCID. At this time, the data received by the receiving terminal is erroneous data. In this application scenario, the local receiving terminal (such as the local UE) directly discards the data in the first information, for example, discards the PDU in the first information, or discards the subPDU in the received first information, that is, it discards the data while receiving the data.

[0084] based on Figure 4In the first identification information and the second identification information in the embodiment, in one application, the first identification information may also include the source domain in the first information, and correspondingly, the second identification information also includes the destination ID configured by the receiving terminal. Therefore, when the receiving terminal determines whether to discard the data in the first information based on the first identification information, LCID and the second identification information, that is, when the receiving terminal specifically performs the above step S103, any of the following methods may be specifically performed:

[0085] The first method: if the source domain in the first information does not match the destination ID configured for the receiving terminal, and the destination domain in the first information matches the source ID configured for the receiving terminal, a receiving operation is performed on the first information.

[0086] The source domain in the first information does not match the destination ID configured for the receiving terminal, and the destination domain in the first information matches the source ID configured for the receiving terminal. This situation indicates that the data sent by the sending terminal is sent to the receiving terminal, and the receiving terminal needs to receive the data. Therefore, in this case, the receiving terminal receives the first information.

[0087] For example, assuming that the receiving terminal is a UE, the source field in the first information received by the UE does not match the UE's own destination ID, and the destination field in the first information received by the UE matches the UE's own sourceID, then the UE performs a receiving operation on the first information.

[0088] The second method: If the source domain in the first information does not match the destination ID configured for the receiving terminal, and the destination domain in the first information matches the source ID configured for the receiving terminal, and the LCID is not a specific LCID, the data in the first information is discarded.

[0089] The source domain in the first information does not match the destination ID configured for the receiving terminal, and the destination domain in the first information matches the source ID configured for the receiving terminal, and the LCID is not a specific LCID. This situation indicates that the data sent by the sending terminal is sent to the receiving terminal, and the receiving terminal needs to receive the data, but the received data contains erroneous data and needs to be processed. Therefore, in this case, the receiving terminal receives the first information but discards all or part of the data in the first information.

[0090] For example, assuming that the receiving terminal is a UE, the source field in the first information received by the UE and the UE's own destination ID do not match, and the destination field in the first information received by the UE and the UE's own sourceID match, and the LCID in the first identification information received by the UE is not LCID-0 or LCID-1 used to transmit PC5-S, then the UE discards all or part of the data in the first information.

[0091] The third method: If the source domain in the first information matches the destination ID configured for the receiving terminal, and the destination domain in the first information matches the source ID configured for the receiving terminal, and the LCID is not the configured LCID, the data in the first information is discarded.

[0092] The source domain in the first information matches the destination ID configured for the receiving terminal, and the destination domain in the first information matches the source ID configured for the receiving terminal, and the LCID is not the configured LCID. This situation indicates that the sending terminal hopes to establish a connection with the receiving terminal, and the data sent by the sending terminal is sent to the receiving terminal. The receiving terminal needs to receive the data, but the received data contains erroneous data and needs to be processed. Therefore, in this case, the receiving terminal receives the first information but discards all or part of the data in the first information.

[0093] For example, assuming that the receiving terminal is a UE, the source field in the first information received by the UE matches the UE's own destination ID, and the destination field in the first information received by the UE matches the UE's own source ID, and the LCID in the first identification information received by the UE is not the configured LCID, then the UE discards all or part of the data in the first information.

[0094] It should be noted that the method for determining whether the source domain in the first information in S1031, S1032, and S1033 matches the destination ID configured for the receiving terminal can refer to the aforementioned method for determining whether the destination domain in the first information matches the source ID configured for the receiving terminal, that is, if the high data bits of the source domain in the first information and the destination ID configured for the receiving terminal match; and / or, if the low data bits of the source domain in the first information and the destination ID configured for the receiving terminal match, then it is determined that the source domain in the first information and the destination ID configured for the receiving terminal match. The specific method can be found in the aforementioned description and will not be repeated here.

[0095] In summary of all the above embodiments, the present application also provides an information processing method, such as Figure 5 As shown, the method includes:

[0096] S201, obtaining first information of a sending terminal, wherein the first information includes first identification information and a logical channel identification LCID, the first identification information includes a destination domain in the first information, and the second identification information includes a source ID configured by the receiving terminal.

[0109] The above steps are basically consistent with the method described in the above embodiment. Please refer to the above description for details, which will not be repeated here.

[0110] Figure 3A-Figure 6 The method described in the embodiment provides an information processing method applied in a MAC layer data transmission scenario. Figure 7-Figure 8 The embodiment will provide an information processing method applied on the adaptation layer.

[0111] In one embodiment, Figure 7 As shown, an information processing method is provided, which is applied to Figure 3A The receiving terminal in the example is used as an example to illustrate, including the following steps:

[0112] S401, receiving first information sent by a sending terminal, where the first information includes identification information in an adaptation layer PDU.

[0113] The sending terminal may be a remote UE, a relay UE, or a network device (such as Figure 3B UE to network relay application scenario), it can also be a source UE or a relay UE in a UE to UE relay application scenario (such as Figure 3C Based on the above two application scenarios, the first information may be a remote terminal (for example, Figure 3B The Remote UE in the relay terminal (for example, Figure 3B The first information may be information received by the relay terminal from a network device (eg, Figure 3B The first information may be information received by the relay terminal from the remote terminal; the first information may be information received by the destination terminal (for example, Figure 3C The DestinationUE in the relay terminal (for example, Figure 3C The first information may be information received by the relay terminal from the source terminal (for example, Figure 3C The identification information includes the first UE ID and / or the first bearer ID in the adaptation layer PDU. Optionally, the identification information includes at least one of the second UE ID, the third UE ID and the second bearer ID in the adaptation layer PDU, wherein the second UE ID corresponds to the destination ID, and the third UE ID corresponds to the source ID.

[0114] S402: Determine whether to discard the adaptation layer PDU according to the identification information.

[0115] The adaptation layer PDU may be the entire PDU of the adaptation layer, or may be a sub-PDU (subPDU) of the adaptation layer.

[0116] In this embodiment, when the receiving terminal receives data from the sending terminal, it can further determine whether the first information meets the preset discarding condition. If so, it means that erroneous data appears in the first information and needs to be discarded, and the operation of discarding the adaptation layer PDU is performed; if not, it means that no erroneous data appears in the first information, and the receiving terminal does not need to discard the received first information.

[0117] It should be noted that when the above-mentioned discarding process is performed, the adaptation layer PDU is discarded, and the adaptation layer PDU can be specifically discarded, for example, the entire received PDU is discarded; or, the adaptation layer sub-PDU is discarded, for example, one received sub-PDU is discarded, and the remaining received sub-PDUs are retained.

[0118] The above preset discarding conditions can be determined according to the actual transmission application scenario. When the receiving terminal receives data sent by different sending terminals, the corresponding preset discarding conditions are also different. The following describes several scenarios where different receiving terminals receive data from different sending terminals:

[0119] For example, when applied in Figure 3B In the transmission scenario shown:

[0120] Example 1, if Figure 3B When the Remote UE in the first information receives the first information sent by the Relay UE, the preset discard condition can be determined by matching the first UE ID of the adaptation layer PDU in the first information and the UE ID configured for the Remote UE, or by matching the first bearer ID of the adaptation layer PDU in the first information and the bearer ID configured for the Remote UE, or by successively matching the first UE ID of the adaptation layer PDU in the first information and the UE ID configured for the Remote UE, and the first bearer ID of the adaptation layer PDU in the first information and the bearer ID configured for the Remote UE.

[0121] Example 2, if Figure 3BWhen the Relay UE in the first information is received from the 5GC device, the preset discard condition can be determined by matching the first UE ID of the adaptation layer PDU in the first information and the UE ID configured for the Relay UE itself, or by matching the first bearer ID of the adaptation layer PDU in the first information and the bearer ID configured for the Relay UE itself, or by successively matching the first UE ID of the adaptation layer PDU in the first information and the UE ID configured for the Relay UE itself, and the first bearer ID of the adaptation layer PDU in the first information and the bearer ID configured for the Relay UE itself. Optionally, it can also be determined by matching the first UEID of the adaptation layer PDU in the first information and the UE ID configured for the related Remote UE by the Relay UE, or by matching the first bearer ID of the adaptation layer PDU in the first information and the bearer ID configured for the related Remote UE by the Relay UE.

[0122] Example three, if Figure 3B When the Relay UE in the first information receives the first information sent by the Remote UE, the preset discard condition can be determined by matching the first UE ID of the adaptation layer PDU in the first information and the UE ID configured for the Relay UE itself, or by matching the first bearer ID of the adaptation layer PDU in the first information and the bearer ID configured for the Relay UE itself, or by successively matching the first UE ID of the adaptation layer PDU in the first information and the UE ID configured for the Relay UE itself, and the first bearer ID of the adaptation layer PDU in the first information and the bearer ID configured for the Relay UE itself. Optionally, it can also be determined by matching the first UE ID of the adaptation layer PDU in the first information and the UE ID configured for the Remote UE of the Relay UE, or by matching the first bearer ID of the adaptation layer PDU in the first information and the bearer ID configured for the Remote UE of the Relay UE, or by successively matching the first UE ID of the adaptation layer PDU in the first information and the UE ID configured for the Remote UE of the Relay UE, and the first bearer ID of the adaptation layer PDU in the first information and the bearer ID configured for the Remote UE of the Relay UE.

[0123] For example, when applied in Figure 3C In the transmission scenario shown:

[0124] Example 4, if Figure 3CWhen the Destination UE receives the first information sent from the UE-to-UE Relay UE, the preset discarding condition can be determined according to the second UE ID of the matching adaptation layer PDU and the UE ID configured for itself by the Destination UE; it can also be determined according to the second UE ID of the matching adaptation layer PDU and the UE ID configured for the related Source UE by the Destination UE, or it can be determined according to the second UEID of the matching adaptation layer PDU and the bearer ID configured for the Destination UE.

[0125] Example 5, if Figure 3C When the UE-to-UE Relay UE in receives the first information sent from the Source UE, the preset discarding condition can be determined according to the second UE ID of the matching adaptation layer PDU and the UE ID configured for the UE-to-UE Relay UE itself; or, according to the second UE ID of the matching adaptation layer PDU and the UE ID configured for the related Destination UE by the UE-to-UE Relay UE, or according to the third UEID of the matching adaptation layer PDU and the UE ID configured for the Source UE, or according to the second bearer ID of the matching adaptation layer PDU and the bearer ID configured for the UE-to-UE Relay UE itself, or according to the second bearer ID of the matching adaptation layer PDU and the bearer ID configured for the related Destination UE by the UE-to-UE Relay UE, or according to the second bearer ID of the matching adaptation layer PDU and the bearer ID configured for the Source UE.

[0126] The information processing method provided in the above embodiment receives the first information including the identification information in the adaptation layer PDU, and determines whether to discard the adaptation layer PDU according to the identification information. The method implements a method for processing error information in the transmission of the adaptation layer PDU. Moreover, since the identification information includes the UE ID and / or the first bearer ID, the error information processing is implemented in combination with the UE ID and / or the first bearer ID, which can improve the accuracy of the error information processing, thereby improving the continuity and efficiency of the receiving terminal receiving data.

[0127] Above Figure 7In the method described in embodiment S402, when the first information is information received by the first terminal from the relay terminal, a method for implementing the above S402 by the receiving terminal is provided, and the method specifically includes: if the identification information satisfies the first condition, discarding the adaptation layer PDU; wherein the first condition includes at least one of the following:

[0128] First item: the first UE ID in the adaptation layer PDU is not the UE ID configured for the first terminal;

[0129] Second item: the first bearer ID in the adaptation layer PDU is not the bearer ID configured for the first terminal.

[0130] The first terminal is a remote terminal, for example, Figure 3B Remote UE in.

[0131] In this embodiment, when the first terminal receives the first information from the relay terminal, the first terminal determines whether the first UE ID in the adaptation layer PDU included in the first information is consistent with the UE ID configured for the first terminal. If not, the adaptation layer PDU is discarded; if consistent, the operation of discarding the adaptation layer PDU is not performed; optionally, the first terminal can also determine whether the first bearer ID in the adaptation layer PDU is consistent with the bearer ID configured for the first terminal. If not, the adaptation layer PDU is discarded; if consistent, the operation of discarding the adaptation layer PDU is not performed; optionally, the first terminal can first determine the first UE in the adaptation layer PDU included in the first information. Whether the ID is consistent with the UEID configured for the first terminal by the first terminal, if consistent, further determine whether the first bearer ID in the adaptation layer PDU is consistent with the bearer ID configured for the first terminal, if inconsistent, discard the adaptation layer PDU, if consistent, do not perform the operation of discarding the adaptation layer PDU; Optionally, the first terminal may first determine whether the first bearer ID in the adaptation layer PDU is consistent with the bearer ID configured for the first terminal, if consistent, further determine whether the first UE ID in the adaptation layer PDU included in the first information is consistent with the UE ID configured for the first terminal, if inconsistent, discard the adaptation layer PDU, if consistent, do not perform the operation of discarding the adaptation layer PDU. The above method can be referred to the example of the above example one, which will not be repeated here.

If it is inconsistent, the adaptation layer PDU is discarded. If it is consistent, the operation of the adaptation layer PDU is not performed. Optionally, the relay terminal can also first determine whether the first UE ID in the adaptation layer PDU included in the first information is consistent with the UE ID configured for the relevant second terminal by the relay terminal.
