1 / 49 INFORMATION PROCESSING METHOD, INFORMATION TRANSMISSION METHOD, APPARATUS, TERMINAL AND DEVICE OF NETWORK CROSS-REFERENCE ON RELATED REQUEST

[0001] This disclosure claims priority from Chinese patent application No. 202310367395.8, filed with the CNIPA on April 7, 2023, and entitled “information processing method, information transmission method, apparatus, terminal and network device”, the disclosure of which is incorporated herein by reference in its entirety. TECHNICAL AREA

[0002] This disclosure relates to the field of communication technology and, in particular, to a method of information processing, a method of information transmission, an apparatus, a terminal and a network device. BACKGROUND

[0003] The 5G user plane air interface protocol layers include the Service Data Adaptation Protocol (SDAP) layer, the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, the Media Access Control (MAC) layer, and the physical layer.

[0004] When a Quality of Service (QoS) stream arrives at the SDAP layer, it maps the QoS stream to a Radio Data Carrier (DRB) and then forms an SDAP Protocol Data Unit (PDU). The SDAP PDU is a PDCP Service Data Unit (SDU). The PDCP layer performs header compression and encryption on the PDCP SDU before delivering it to the RLC layer. The RLC layer then encapsulates the RLC PDU based on scheduling information from the MAC layer and delivers it to the MAC layer. The MAC layer encapsulates the received RLC PDU into a MAC PDU and then delivers it to the physical layer for transmission. Petition 870250086052, dated 09 / 23 / 2025, page 8 / 228 2 / 49

[0005] Traditionally, upon receiving an SDU from an upper layer, the PDCP layer initiates a PDCP discard timer for the SDU. When the PDCP discard timer expires, the PDCP SDU is discarded. The conventional SDU discard mechanism only considers the influence of delay and does not consider the existence of congestion. In scenarios where congestion occurs, it is necessary to consider how to alleviate the congestion. SUMMARY

[0058] The related concepts mentioned in this disclosure are briefly described below.

[0059] Introduction to the Extended Reality (XR) service

[0060] XR and cloud gaming (CG) are among the most important media applications of 5G. XR is a general term for different types of reality, referring to all combined real and virtual environments and human-computer interactions generated by technology and computing devices. It includes augmented reality (AR), mixed reality (MR), virtual reality (VR), and similar technologies.

[0061] XR services are modeled based on data frames. A data frame can be divided into several PDUs, and the various PDUs can be considered a PDU set, as shown in Figure 1. From the perspective of the radio access network (RAN), a PDU set is a collection of data packets sent from an upper layer to the RAN, where these data packets share the Petition 870250086052, dated 09 / 23 / 2025, page 20 / 228 14 / 49 same QoS attributes.

[0062] The following describes embodiments of this disclosure with reference to the accompanying drawings. The information processing method, the information transmission method, the apparatus, the terminal, and the network device provided by the embodiments of this disclosure can be applied in a wireless communication system. The wireless communication system may be a system employing fifth-generation (5G) mobile communication technology (hereinafter referred to as the 5G system). Skilled individuals will understand that the 5G NR system is merely an example and this disclosure is not limited to it.

[0063] The embodiments of this disclosure provide a method of information processing, a method of information transmission, an apparatus, a terminal and a network device for alleviating congestion.

[0064] The method and the apparatus are based on the same innovative concept. Since the principles of problem-solving by the method and the apparatus are similar, for the implementation of one of the apparatuses and the method, reference can be made to the other, and repeated parts will not be described again.

[0065] As shown in Fig. 2, one embodiment of the present disclosure provides a method of information processing performed by a terminal and includes: Step S201: Receive the first configuration information sent by a network device, where the first configuration information includes an association between a first target object and a time duration of a discard timer; Step S202: Determine, based on the initial configuration information, the association between the first target object and the discard timer duration.

[0066] In some embodiments, the discard timer may be a Petition 870250086052, dated 09 / 23 / 2025, page 21 / 228 15 / 49 Packet Data Convergence Protocol Disposal Timer (PDCP Disposal Timer) or a newly introduced timer; the association may be called a mapping relationship or matching relationship.

[0067] In some embodiments, the first target object includes at least one of the following A11 or A12.

[0068] A11. Terminal congestion level.

[0069] In some modes, the congestion level is identified by N bits, and the N bits are used to indicate 2N congestion levels; where N is an integer greater than or equal to 1.

[0070] For example, the congestion level is indicated by 1 bit and includes two congestion levels: Congestion and No Congestion. Alternatively, the congestion level is indicated by 3 bits and includes 8 congestion levels.

[0071] A12. attribute of a set of PDUs.

[0072] In some modes, the attribute of the PDU set includes at least one of the following: A121. a priority of the PDU set; A122. The importance of the PDU set; A123. a PDU set delay budget (PSDB).

[0073] It should be noted that by reasonably setting the time duration based on the congestion level and / or PDU set attributes, and using the first configuration information to set up the association between the terminal congestion level and / or PDU set attributes and the discard timer duration for the terminal, the terminal can determine the appropriate time duration based on the association and then discard packets. Petition 870250086052, dated 09 / 23 / 2025, p. 22 / 228 16 / 49 data based on time duration to alleviate congestion as much as possible.

[0074] In some embodiments, the initial configuration information in the embodiments of this disclosure may be configured by the network device on a per-terminal basis, i.e., the associations obtained by different terminals may be different from one another; the initial configuration information may also be configured on a per-terminal data radio carrier (DRB), i.e., the associations determined for different DRBs of the same terminal may be different from one another.

[0075] In some embodiments, the first configuration information may be carried by radio resource control (RRC) signaling or media access control element (MAC CE).

[0076] In some modes, before receiving the first configuration information sent by the network device, the method also includes: Report the initial information to the network device.

[0077] The first piece of information includes at least one of the following B11 to B15.

[0078] B11. The terminal supports a discard function based on the first target object.

[0079] For example, the terminal supports a discard function based on a terminal congestion level and / or the terminal supports a discard function based on an attribute of a set of PDUs.

[0080] B12. The terminal supports a discard function based on the set of PDU.

[0081] B13. A congestion level supported by the terminal.

[0082] For example, the number of congestion levels supported by the terminal is reported here.

[0083] B14. Terminal congestion level. Petition 870250086052, dated 09 / 23 / 2025, page 23 / 228 17 / 49

[0084] B15. The display information indicates that there is congestion at the terminal.

[0085] For example, 1 bit is used to indicate that the terminal is congested. When the indicator information is 1, it indicates that the terminal is congested. Alternatively, the indicator information being 0 indicates that the terminal is congested.

[0086] In some forms, after obtaining the association, the method according to the form of this disclosure also includes: Based on the association and the second piece of information, determine a discard timer duration corresponding to a second target object; where the second target object includes at least one of the following: a Packet Data Convergence Protocol (PDCP) service data unit (SDU) or a set of PDUs.

[0087] In some forms, the second piece of information includes at least one of the following: C11. the level of congestion at the terminal; or C12. an attribute of the PDU set corresponding to the second target object.

[0088] For example, when the terminal needs to discard a PDU set, if the determined association is the association between the terminal's congestion level and the discard timer's duration, the terminal needs to determine the discard timer's duration corresponding to the current congestion level based on the association and the current congestion level, and then execute the discard timer based on the timer's duration; for example, when the terminal needs to discard a PDU set, if the determined association is the association between the terminal's congestion level and the PDU set's priority and the discard timer's duration, the terminal needs to determine the timer's duration. Petition 870250086052, dated 09 / 23 / 2025, page 24 / 228 18 / 49 discard corresponding to the current congestion level and priority of the PDU set based on the association and the current congestion level and priority of the PDU set, and then execute the discard timer based on the timer's duration.

[0089] In some embodiments, the method according to the embodiment of this disclosure also includes: receive a second configuration message sent by the network device, where the second configuration message is used to indicate to the terminal whether to apply the first configuration message.

[0090] In other words, in this case, whether the terminal should apply the first configuration information can be configured by the network device. Only when the network device configures the terminal to apply the first configuration information can the terminal apply the first configuration information upon receiving the first configuration information. It should be noted that a terminal applying the first configuration can be understood as: the terminal receives the first configuration information and determines the discard timer duration based on the first configuration information; a terminal not applying the first configuration can be understood as: the terminal receives the first configuration information and does not determine the discard timer duration based on the first configuration information.

[0091] In some embodiments, the second configuration information may be carried by RRC signaling or a CE MAC.

[0092] In some embodiments, the second configuration information satisfies at least one of the following: The second configuration information is configured by the terminal; or the second configuration information is configured by DRB.

[0093] In other words, in the modality of the present disclosure, the second piece of information of Petition 870250086052, dated 09 / 23 / 2025, page 25 / 228 19 / 49 configuration can be set by the network device based on each terminal, meaning different terminals may receive different information about whether or not to apply the first configuration information; the second configuration information can also be set based on each terminal's DRB, meaning the information about whether or not to apply the first configuration information that is determined for different DRBs of the same terminal may differ from one another.

[0094] In some embodiments, the method according to the embodiment of this disclosure also includes: receive the third configuration information sent by the network device, where the third configuration information is used to indicate whether a second target object should be discarded when a discard timer corresponding to the second target object expires.

[0095] That is, in this case, if the terminal is to discard the second target object when the discard timer corresponding to the second target object expires, it is configured by the network device; furthermore, in some embodiments, after receiving the third configuration information, the method according to the embodiment of this disclosure also includes: Determine, based on the third configuration information, whether to discard the second target object when the discard timer corresponding to the second target object expires.

[0096] It can be understood that: only when the network device configures the terminal to discard the second target object when the discard timer corresponding to the second target object expires, can the terminal discard the second target object when the discard timer corresponding to the second target object expires; if the network device configures the terminal not to discard the second target object when the discard timer corresponding to the second target object expires Petition 870250086052, dated 09 / 23 / 2025, page 26 / 228 20 / 49 expires, even if the discard timer corresponding to the second target object expires, the terminal will not discard the second target object.

[0097] In some embodiments, an implementation to determine, based on the third configuration information, whether the second target object should be discarded when the discard timer corresponding to the second target object expires includes: If the terminal is not in a congested state or the terminal's congestion level is less than or equal to a first threshold, determine, according to the third configuration information, whether to discard the second target object when the discard timer corresponding to the second target object expires.

[0098] Note that when the terminal is not in a congested state or the terminal congestion level is less than or equal to a first threshold, the terminal cannot discard the second target object. At this time, if the discard timer is started for the second target object, when the discard timer expires, it will still be necessary to determine the specific content of the third configuration information when deciding whether the second target object will be discarded. If the third configuration information is used to indicate that the second target object should be discarded when the discard timer corresponding to the second target object expires, when the discard timer expires, the second target object will be discarded directly.If the third configuration information is used to indicate that the second target object should not be discarded when the discard timer corresponding to the second target object expires, then when the discard timer expires, the terminal will not discard the second target object.

[0099] In some embodiments, after receiving the third configuration information, the method according to the embodiment of this disclosure also includes: Petition 870250086052, dated 09 / 23 / 2025, page 27 / 228 21 / 49 In the event that the terminal is in a congested state or the terminal congestion level exceeds a first threshold, determine the disposal of a second target object when a disposal timer corresponding to the second target object expires.

[0100] It should be noted here that when the terminal is congested or the terminal congestion level is higher than the first threshold, the terminal needs to discard the second target object. In this case, even if the third configuration information is received, the content of the third configuration information is not considered, i.e., the third configuration information is ignored. While the discard time expires, the terminal will discard the second target object.

[0101] In some embodiments, the third configuration information may be carried via RRC signaling or a CE MAC.

[0102] Specific implementations of the modality of this disclosure are described below with examples.

[0103] Application scenario 1: The first configuration information includes an association between the congestion level, the PDU set attribute, and the disposal timer duration.

[0104] The specific implementation process includes the following steps 11 and 12.

[0105] Step 11: The terminal receives the first configuration information sent by the network device.

[0106] The terminal receives the first configuration information sent by the network device and determines the association between the congestion level, the PDU set attribute, and the discard timer duration through the first configuration information.

[0107] The initial configuration information can be carried by RRC signaling or by a CE MAC. The discard timer can be a PDCP discard timer of the related technique or a newly introduced timer. Petition 870250086052, dated 09 / 23 / 2025, page 28 / 228 22 / 49

[0108] It is assumed that there are only two congestion levels (No congestion and Congestion, represented by 0 and 1, respectively). The importance of the PDU set is taken as an example of the PDU set attribute. It is assumed that the importance of the PDU set has 16 levels and that there are three discard timer durations. The possible content of the first configuration information is shown in Table 1: Table 1. Association between congestion level, PDU set attribute, and discard timer duration. Congestion Level | PDU Set Attribute | PDCP Discharge Timer Duration | 0 | 1~16 | 100 ms | 1 | 1~8 | 100 ms | 9~16 | 0 ms Table 1

[0109] Step 12: The terminal discards the PDCP SDU based on the initial configuration information.

[0110] After receiving the initial configuration information, the terminal determines the PDCP discard timer duration corresponding to the PDU set according to the current congestion level and the PDU set attribute.

[0111] For example, if the current congestion level is 1 and the PDU set attribute is 15, it is determined that the PDCP discard timer duration is 0, meaning the data packet corresponding to the PDU set is discarded directly upon reaching the PDCP layer.

[0112] Application scenario 2: The first configuration information contains only an association between the congestion level and the duration of time. Petition 870250086052, dated 09 / 23 / 2025, page 29 / 228 23 / 49 discard timer.

[0113] The specific implementation process includes the following steps 21 and 22.

[0114] Step 21: The terminal receives the first configuration information sent by the network device.

[0115] The terminal receives the first configuration information sent by the network device and determines the association between the congestion level and the discard timer duration through the first configuration information.

[0116] The first configuration information can be carried by RRC signaling or by a CE MAC. The discard timer can be a PDCP discard timer of the related technique or a newly introduced timer.

[0117] It is assumed that there are only two congestion levels (No congestion and Congestion, represented by 0 and 1, respectively) and three time durations for the discard timer. The possible content of the first configuration information is shown in Table 2: Table 2. Association between congestion level and disposal timer duration. Jam level PDCP discard timer duration 0 100 ms 1 0 ms Table 2

[0118] Step 22: The terminal discards the PDCP SDU based on the initial configuration information.

[0119] After the terminal receives the first configuration information, the terminal determines the PDCP discard timer duration corresponding to the PDU set according to the current congestion level. Petition 870250086052, dated 09 / 23 / 2025, page 30 / 228 24 / 49

[0120] For example, if the current congestion level is 1, the discard timer duration is set to 0, meaning the data packet corresponding to the PDU set is discarded directly when it reaches the PDCP layer.

[0121] Application scenario 3: The terminal receives the first configuration information sent by the network device, and the application of the first configuration information is determined based on the second configuration information.

[0122] The specific implementation process includes the following steps 31 to 33.

[0123] Step 31: The terminal receives the first configuration information sent by the network device.

[0124] The terminal receives the first configuration information sent by the network device and determines the association between the congestion level, the PDU set attribute, and the discard timer duration through the first configuration information.

[0125] The first configuration information can be carried by RRC signaling or by a CE MAC. The discard timer can be a PDCP discard timer of the related technique or a newly introduced timer.

[0126] It is assumed that there are only two congestion levels (No congestion and Congestion, represented by 0 and 1, respectively). The importance of the PDU set is taken as an example of the PDU set attribute. It is assumed that the importance of the PDU set has 16 levels and that there are three discard timer durations. The possible content of the first configuration information is shown in Table 1.

[0127] Step 32: The terminal receives the second configuration information.

[0128] When congestion occurs at a terminal, it reports its current congestion status to the network device. The specific reporting method may be one of the following: the terminal reports the current congestion level of Petition 870250086052, dated 09 / 23 / 2025, page 31 / 228 25 / 49 terminal to the network device, and the terminal informs the network device that congestion has occurred at the terminal.

[0129] After receiving the terminal report, the network device determines whether to send a second configuration message to the terminal. The second configuration message is used to indicate to the terminal whether the first configuration message should be applied. The second configuration message can be transmitted using RRC signaling or a CE MAC.

[0130] Step 33: The terminal discards the PDCP SDU based on the initial configuration information.

[0131] For example, after receiving the second configuration information, the terminal determines to apply the first configuration information received in step 31. The terminal determines the discard timer duration corresponding to the PDU set according to the current congestion level and the PDU set attribute.

[0132] For example, if the current congestion level is 1 and the PDU set attribute (importance of the PDU set) is 15, it is determined that the PDCP discard timer duration is 0, that is, the data packet corresponding to the PDU set is discarded directly upon arrival at the PDCP layer.

[0133] Application scenario 4: The terminal receives the first configuration information sent by the network device and performs packet discarding in conjunction with the third configuration information.

[0134] The specific implementation process includes the following steps 41 to 43.

[0135] Step 41: The terminal receives the first configuration information sent by the network device.

[0136] The terminal receives the first configuration information sent by the network device and determines the association between the congestion level, the Petition 870250086052, dated 09 / 23 / 2025, page 32 / 228 26 / 49 attribute of the PDU set and the discard timer duration based on the first configuration information. The discard timer can be a PDCP discard timer from the related technique or a newly introduced timer.

[0137] The first configuration information can be carried by RRC signaling or by a CE MAC.

[0138] It is assumed that there are only two congestion levels (No congestion and Congestion, represented by 0 and 1, respectively). The importance of the PDU set is taken as an example of the PDU set attribute. It is assumed that the importance of the PDU set has 16 levels and that there are three discard timer durations. The possible content of the first configuration information is shown in Table 1.

[0139] Step 42: The terminal receives the second configuration information.

[0140] It is worth noting that step 42 is optional and may not be performed.

[0141] When congestion occurs at a terminal, it reports its current congestion status to the network device. The specific reporting method can be one of the following: the terminal reports the current congestion level of the terminal to the network device, and the terminal reports to the network device that congestion has occurred at the terminal.

[0142] After receiving the terminal report, the network device determines whether to send a second configuration message to the terminal. The second configuration message is used to indicate to the terminal whether the first configuration message should be applied. The second configuration message can be transmitted using RRC signaling or a CE MAC.

[0143] Step 43: The terminal discards the PDCP SDU based on the initial configuration information.

[0144] If step 42 is executed, after receiving the second piece of information Petition 870250086052, dated 09 / 23 / 2025, page 33 / 228 27 / 49 configuration, the terminal determines to apply the first configuration information received in step 41. If step 42 is not executed, step 43 may be executed.

[0145] In some embodiments, the terminal may also receive a third configuration piece of information from a network device, wherein the third configuration piece of information is used to indicate whether a set of SDUs or PDCP PDUs should be discarded when a discard timer corresponding to the set of SDUs or PDCP PDUs expires. In addition, the network device needs to obtain the third configuration piece of information from the main network. The third configuration piece of information may be carried by RRC signaling or a CE MAC.

[0146] Specifically, packet disposal management can be performed based on third configuration information and first configuration information in one of the following ways.

[0147] In the case where the terminal is not in a congested state or the terminal congestion level is less than or equal to a first threshold, determine, according to the third configuration information, whether to discard the PDCP SDU or PDU set when the discard timer corresponding to the PDCP SDU or PDU set expires; for example, if the third configuration information indicates that the PDCP SDU or PDU set needs to be discarded when the discard timer corresponding to the PDCP SDU or PDU set expires, the discard operation will be executed when the discard timer expires; otherwise, the discard operation will not be executed.

[0148] If the terminal is in a congested state or the terminal congestion level is greater than a first threshold, the third configuration information will be ignored and a discard operation will be performed when a discard timer corresponding to the PDCP SDU or PDU set expires.

[0149] In summary, at least one embodiment of the present disclosure provides a Petition 870250086052, dated 09 / 23 / 2025, page 34 / 228 28 / 49 is a congestion-related packet discard management method, through which congestion can be alleviated as much as possible, ensuring QoS.
