[0004] Some characteristics of XR services are as follows:

[0005] -The video frame period is 15 / 30 / 60 / 90 / 80fps (frames per second), corresponding to the period of 66.6 / 33.3 / 16.66 / 8.87ms respectively;

[0006] - Frame arrival time has unpredictable jitter;

[0007] - Latency requirement: 10ms or 7-15ms range;

[0153] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0154] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0155] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0156] In the embodiment of the present application, the terminal sends auxiliary information to the network, so that the network can directly obtain the PSER of the uplink PDU Set or calculate the PSER of the uplink PDU Set based on the auxiliary information.

[0157] like Figure 3 As shown, an information sending method provided in an embodiment of the present application is applied to a terminal, including:

[0158] Step 301, sending auxiliary information to the network device, the auxiliary information including first information and / or second information, wherein the first information is the PSER of the PDU Set of the target object in the uplink transmission direction, and the second information is information used to determine the PSER of the target object in the uplink transmission direction; wherein the target object is the terminal, the service quality flow (QoS flow) of the terminal, the radio bearer (Radio Bearer, RB) of the terminal or the logical channel (Logical CHannel, LCH) of the terminal.

[0159] Here, the terminal sends auxiliary information to the network device. When the auxiliary information includes the first information, the network device can directly obtain the PSER of the PDU Set of the target object in the uplink transmission direction from the auxiliary information; when the auxiliary information includes the second information, the network device can calculate the PSER of the PDU Set of the target object in the uplink transmission direction based on the second information.

[0160] Specifically, the second information may include first sub-information and / or second sub-information; wherein,

[0161] The first sub-information includes at least one of the following information: a first number of PDU Sets belonging to the target object received from a higher layer; a second number of PDU Sets to be sent by the target object in an uplink transmission direction. Here, the higher layer may be a relevant protocol layer of the core network, such as an IP layer.

[0162] The second sub-information includes at least one of the following information: the third number of PDU Sets that are not successfully transmitted in the uplink transmission direction of the target object; the sequence number of the PDU Set that is not successfully transmitted in the uplink transmission direction of the target object; the sequence number of the PDCP PDU that is not successfully transmitted in the uplink transmission direction of the target object, and identification information of whether the PDCP PDU belongs to a PDU Set.

[0163] When the second sub-information includes the sequence number of the PDU Set that was not successfully transmitted in the uplink transmission direction of the target object, the network device can count the number of PDU Sets that were not successfully transmitted in the uplink transmission direction of the target object based on the sequence number of the PDU Set that was not successfully transmitted.

[0164] Similarly, when the second sub-information includes the sequence number of the PDCP PDU that is not successfully transmitted in the uplink transmission direction of the target object and the identification information of whether the PDCP PDU belongs to a PDU Set, the network device can count the unsuccessfully transmitted PDU Sets based on the sequence number of the PDCP PDU that is not successfully transmitted in the uplink transmission direction and the identification information of whether the PDCP PDU belongs to a PDU Set, thereby obtaining the number of PDU Sets that are not successfully transmitted in the uplink transmission direction of the target object.

[0165] In an embodiment of the present application, the terminal obtains the number of unsuccessfully transmitted PDU Sets based on the PDU Sets or PDCP PDUs that are not successfully transmitted by the statistical target object in the uplink transmission direction, or records the sequence number of the unsuccessfully transmitted PDU Set, or records the sequence number of the unsuccessfully transmitted PDCP PDU and identification information of whether the PDCP PDU belongs to a PDU Set.

[0166] Specifically, the PDU Set that is not successfully transmitted by the target object in the uplink transmission direction may include at least one of the following:

[0167] (1) PDU Set discarded due to PDCP discard timer expiration or PDCP Set discard timer expiration.

[0168] Here, when the PDCP discard timer times out, the terminal will discard the corresponding PDCP PDU, thereby causing the PDU Set to which the PDCP PDU belongs to fail to transmit. When the PDCP Set discard timer times out, the terminal will discard the corresponding PDCP Set, thereby causing the PDU Set to fail to transmit.

[0169] (2) PDU Set that is discarded due to transmission failure due to channel quality issues.

[0170] Here, due to reasons such as poor channel quality, data transmission may fail, resulting in the relevant PDU Set being discarded.

[0171] In an embodiment of the present application, the terminal may carry the auxiliary information through a UE Assistance Information (UE Assistance Information, UAI) message and / or a Packet Data Convergence Protocol (Packet Data Convergence Protocol, PDCP) control PDU. That is, the terminal may send the auxiliary information to the network device through a UAI message and / or a PDCP control PDU. When sending auxiliary information through a UAI message and a PDCP control PDU, part of the auxiliary information may be carried in the UAI message, and the other part of the information may be carried in the PDCP control PDU. For example, the first information is carried in a UAI message, and the second information is carried in a PDCP control PDU; for another example, the first sub-information is carried in a UAI message, and the second sub-information is carried in a PDCP control PDU.

[0172] In the embodiment of the present application, the terminal may perform the above step 301 when the auxiliary information reporting trigger condition is met. Therefore, before the above step 301, the network device may also detect whether the auxiliary information reporting trigger condition is met; when the auxiliary information reporting trigger condition is met, step 301 is performed to send auxiliary information to the network device. Here, the auxiliary information reporting trigger condition includes at least one of the following: periodic triggering, event triggering.

[0173] Periodic triggering is to trigger the sending of auxiliary information according to a preset period, for example, sending it once every preset time interval. Event triggering is based on event triggering. The event in the event triggering includes at least one of a first event and a second event;

[0174] (1) The first event is: the number of PDU Sets that are not successfully transmitted by the target object in the uplink transmission direction reaches a first threshold. Here, the first threshold can be a threshold set by the terminal, or a threshold configured for the terminal by the network device. The specific value of the threshold can be set according to the data transmission performance and other requirements of the target object, and the embodiment of the present application does not specifically limit this.

[0175] (2) The second event is: any PDU Set of the target object in the uplink transmission direction is not successfully transmitted. Here, the second event means that as long as a PDU Set of the target object in the uplink transmission direction is not successfully transmitted, the auxiliary information sending process of step 301 is triggered.

[0176] In order to provide the network device with a packet error rate (Packet Error Rate, PER) of the target object in the uplink transmission direction, the auxiliary information sent by the terminal may further include third information; wherein the third information includes at least one of the following:

[0177] (1) PER of the target object in the uplink transmission direction;

[0178] (2) a fourth number of PDCP PDUs to be sent by the target object in an uplink transmission direction;

[0179] (3) the reason for unsuccessful transmission of the PDCP PDU of the target object that was not successfully transmitted in the uplink transmission direction, the reason including at least one of the following:

[0180] The PDCP PDU has been transmitted but the transmission fails;

[0181] The PDCP PDU is discarded due to the expiration of the PDCP discard timer corresponding to other PDUs in the PDU Set to which the PDCP PDU belongs;

[0182] The PDCP Set discard timer corresponding to the PDU Set to which the PDCP PDU belongs expires, resulting in the PDCP PDU being discarded.

[0183] Here, the terminal may directly carry the PER of the target object in the uplink transmission direction in the auxiliary information, or may send the above items (2) and (3) so that the network device can calculate the PER of the target object in the uplink transmission direction according to items (2) and (3).

[0184] In addition, in an embodiment of the present application, the auxiliary information sent by the terminal may be data collected by the terminal for the target object within a preset time period. For example, for the first information, it may be the PSER of the PDU Set of the target object in the uplink transmission direction within the preset time period; for the first sub-information, it may include at least one of the following information: the first number of PDU Sets belonging to the target object received from the upper layer within the preset time period; the second number of PDU Sets to be sent by the target object in the uplink transmission direction within the preset time period; for the second sub-information, it may include at least one of the following information: the third number of PDU Sets that were not successfully transmitted in the uplink transmission direction of the target object within the preset time period; the sequence number of the PDU Set that was not successfully transmitted in the uplink transmission direction of the target object within the preset time period; the sequence number of the PDCP PDU that was not successfully transmitted in the uplink transmission direction of the target object within the preset time period, and identification information of whether the PDCP PDU belongs to a PDU Set.

[0185] The preset time period is a time period of preset length, and the terminal can determine the preset time period according to pre-configuration information or protocol agreement. Of course, it can also be configured by the network device. In this case, the terminal can receive first configuration information sent by the network device and determine the preset time period according to the first configuration information.

[0186] Optionally, in an embodiment of the present application, the terminal sends the auxiliary information, which may specifically include: based on periodic triggering, the terminal sends the first sub-information in the auxiliary information to the network device, the first sub-information is carried by a UAI message, and the period of the periodic trigger is the preset time period; and, based on the second event in the event triggering, the serial number of the PDUSet that the target object has not been successfully transmitted in the uplink transmission direction is sent to the network device through the PDCP control PDU, or the serial number of the PDCP PDU that the target object has not been successfully transmitted in the uplink transmission direction and identification information of whether the PDCP PDU belongs to a PDU Set.

[0187] In this way, the network device can obtain the first number of PDU Sets belonging to the target object received by the terminal from the upper layer within the most recent preset time period, or the second number of PDU Sets to be sent by the target object in the uplink transmission direction, based on the first sub-information received most recently; and count the third number of PDU Sets that were not successfully transmitted in the uplink transmission direction of the target object based on the PDCP control PDU received within the most recent preset time period; then, the ratio of the third number to the first number is determined as the PSER of the target object in the uplink transmission direction, or the ratio of the third number to the second number is determined as the PSER of the target object in the uplink transmission direction. Here, the most recent preset time period refers to the time period from the first time to the second time, the second time is the reception time of the most recent received first sub-information, the first time is before the second time, and is separated from the second time by the preset time period.

[0188] Please refer to Figure 4 The information receiving method provided in the embodiment of the present application is applied to a network device, including:

[0189] Step 401, receiving auxiliary information sent by the terminal, the auxiliary information includes first information and / or second information, wherein the first information is the PSER of the target object in the uplink transmission direction, and the second information is information used to determine the PSER of the target object in the uplink transmission direction; wherein the target object is the terminal, the QoSflow of the terminal, the wireless bearer RB of the terminal, or the logical channel of the terminal.

[0190] Specifically, the network device can receive a UAI message and / or PDCP control PDU sent by the terminal, and the UAI message and / or PDCP control PDU carries the auxiliary information, so that the network device can obtain the auxiliary information from the UAI message and / or PDCP control PDU.

[0191] Optionally, the second information includes first sub-information and / or second sub-information; wherein,

[0192] The first sub-information includes at least one of the following information: a first number of PDU Sets belonging to the target object received by the terminal from a higher layer; a second number of PDU Sets to be sent by the target object in an uplink transmission direction;

[0193] The second sub-information includes at least one of the following information: the third number of PDU Sets that are not successfully transmitted in the uplink transmission direction of the target object; the sequence number of the PDU Set that is not successfully transmitted in the uplink transmission direction of the target object; the sequence number of the PDCP PDU that is not successfully transmitted in the uplink transmission direction of the target object, and identification information of whether the PDCP PDU belongs to a PDU Set.

[0194] Here, the PDU Set of the target object that is not successfully transmitted in the uplink transmission direction includes at least one of the following: a PDU Set discarded due to PDCP discard timer expiration or PDCP PDU Set discard timer expiration; a PDU Set discarded due to transmission failure due to channel quality reasons.

[0195] Through the above steps, the network device of the embodiment of the present application can obtain the PSER of the target object on the terminal side in the uplink transmission direction based on the auxiliary information, thereby realizing the reporting of the PSER.

[0196] For example, when the auxiliary information includes the second information, the network device may determine the PSER of the target object in the uplink transmission direction according to the second information.

[0197] Specifically, the network device can obtain, based on the first sub-information, the first number of PDU Sets belonging to the target object received by the terminal from the upper layer or the second number of PDU Sets to be sent by the target object in the uplink transmission direction; based on the second sub-information, obtain the third number of PDU Sets that are not successfully transmitted in the uplink transmission direction of the target object; then, determine the ratio of the third number to the first number as the PSER of the target object in the uplink transmission direction, or determine the ratio of the third number to the second number as the PSER of the target object in the uplink transmission direction.

[0198] After step 401, the network device may adjust the reordering window of the radio link control (RLC) entity corresponding to the target object based on the auxiliary information. For example, according to the PSER, the reordering window of the RLC entity of the target object is adjusted, such as updating the lower boundary of the reordering window.

[0199] Optionally, in the embodiment of the present application, the auxiliary information may further include third information; wherein the third information includes at least one of the following:

[0200] The packet error rate PER of the target object in the uplink transmission direction;

[0201] a fourth number of PDCP PDUs to be sent by the target object in an uplink transmission direction;

[0202] The reason why the target object fails to successfully transmit the PDCP PDU in the uplink transmission direction, the reason including at least one of the following:

[0203] The PDCP PDU has been transmitted but the transmission fails;

[0204] The PDCP PDU is discarded due to the expiration of the PDCP discard timer corresponding to other PDUs in the PDU Set to which the PDCP PDU belongs;

[0205] The PDCP Set discard timer corresponding to the PDU Set to which the PDCP PDU belongs expires, resulting in the PDCP PDU being discarded.

[0206] In a case where the third information includes the fourth number of PDCP PDUs to be sent by the target object in the uplink transmission direction and the reason why the target object failed to successfully transmit the PDCP PDU in the uplink transmission direction, the network device can obtain, based on the third information, the fourth number of PDCP PDUs to be sent by the target object in the uplink transmission direction and the fifth number of PDCP PDUs whose reason for unsuccessful transmission is that the PDCP PDU has been transmitted but failed to transmit; and then, determine the ratio of the fifth number to the fourth number as the PER of the target object in the uplink transmission direction.

[0207] It can be seen that when calculating PER, the embodiment of the present application does not take as part of the fifth quantity the data packets whose reasons for unsuccessful transmission are the timeout of the PDCP discard timer corresponding to other PDUs in the PDU Set to which the PDCP PDU belongs, resulting in the discard of the PDCP PDU, and the timeout of the PDCP Set discard timer corresponding to the PDU Set to which the PDCP PDU belongs, resulting in the discard of the PDCP PDU.

[0208] In addition, the auxiliary information sent by the terminal may be data collected by the terminal for the target object within a preset time period. The network device may send first configuration information to the terminal, and the first configuration information is used to configure the preset time period. Of course, the preset time period may also be determined by the terminal according to pre-configuration information or protocol agreement.

[0209] Optionally, in an embodiment of the present application, the auxiliary information may be carried by a UAI message and a PDCP control PDU. The network device receives the first sub-information in the auxiliary information periodically sent by the terminal, and the period is the preset time period; and receives the second event in the event triggering, and the terminal sends the sequence number of the PDU Set that the target object has not successfully transmitted in the uplink transmission direction to the network device through the PDCP control PDU, or the sequence number of the PDCP PDU that the target object has not successfully transmitted in the uplink transmission direction and the identification information of whether the PDCP PDU belongs to a PDU Set.

[0210] The network device can obtain, based on the first sub-information received most recently, the first number of PDU Sets belonging to the target object received by the terminal from the upper layer within the most recent preset time period, or the second number of PDU Sets to be sent by the target object in the uplink transmission direction; and, based on the PDCP control PDU received within the most recent preset time period, count the third number of PDU Sets that have not been successfully transmitted in the uplink transmission direction of the target object; then, determine the ratio of the third number to the first number as the PSER of the target object in the uplink transmission direction, or determine the ratio of the third number to the second number as the PSER of the target object in the uplink transmission direction. Here, the most recent preset time period refers to the time period from the first time to the second time, the second time is the reception time of the first sub-information received most recently, the first time is before the second time, and is separated from the second time by the preset time period.

[0211] In order to better understand the above embodiments, the present application is further described below through several examples.

[0212] Example 1: Auxiliary information is carried via UAI message

[0213] This example 1 includes the following steps:

[0214] Step S101: The terminal determines whether a triggering condition for sending auxiliary information is met.

[0215] The triggering condition for sending the auxiliary information includes but is not limited to one of the following:

[0216] 1) Periodic triggering;

[0217] 2) Event triggering.

[0218] The period of the periodic trigger may be configured or pre-configured by the network, for example, the configured period is T. The event in the event trigger includes but is not limited to one of the following:

[0219] (1) The number of PDU Sets that are not successfully transmitted reaches a first threshold, where the first threshold can be pre-configured or network configured.

[0220] (2) Any PDU Set of the terminal is not successfully transmitted, for example, the terminal discards a PDU Set.

[0221] Once the triggering condition for sending the auxiliary information is met, the terminal sends the auxiliary information to the network device. The auxiliary information may be carried by, but is not limited to, a UAI message.

[0222] Step S102: The terminal sends auxiliary information to the network device.

[0223] In step S102, the terminal sends auxiliary information to the network device. Specifically, in this example, the terminal sends a UAI message, and the UAI message carries the auxiliary information to send the auxiliary information to the network device. The auxiliary information includes the first information and / or the second information described above.

[0224] In this example, if the auxiliary information includes second information, that is, information used to determine the PSER of the target object in the uplink transmission direction, the second information includes but is not limited to one or more of the following:

[0225] 1) The number of PDU Sets that the terminal failed to transmit successfully in the uplink transmission direction

[0226] 2) The number of PDU Sets received by the terminal from the upper layer or the number of PDU Sets to be sent by the terminal;

[0227] 3) Sequence numbers of the PDCP PDUs corresponding to multiple PDU sets that were not successfully transmitted by the terminal (which may be start and end sequence numbers or all PDCP PDU sequence numbers) and identification information of whether the PDCP PDUs belong to one PDU Set.

[0228] Among them, the number of PDU Sets that the terminal failed to transmit successfully in the uplink transmission direction, the number of PDU Sets received by the terminal from the higher layer or the number of PDU Sets to be sent by the terminal, and the sequence numbers of PDCP PDUs corresponding to multiple PDU sets that the terminal failed to transmit successfully may be statistical data within a period of time (for example, within the T time period).

[0229] The length of the T time period is configured or preconfigured by the network device.

[0230] The unsuccessfully transmitted PDU Set includes but is not limited to one or more of the following:

[0231] 1) PDU Set discarded due to PDCP discard timer expiration;

[0232] 2) PDU Set discarded due to transmission failure caused by channel quality reasons.

[0233] Step S103: The network device performs related operations based on the auxiliary information

[0234] After receiving the auxiliary information, the network device may perform at least one of the following operations:

[0235] 1) Adjusting the reordering window of the RLC entity corresponding to the PDU Set, such as updating the lower boundary of the reordering window;

[0236] 2) Calculate the PSER according to the second information in the auxiliary information.

[0237] An example is given below: Assuming that the number of PDU Sets to be sent by the terminal within a T time period contained in the auxiliary information is M, and the number of PDU Sets that are not successfully transmitted within the T time period is N, then PSER = N / M. The statistical granularity of the PSER can be based on each bearer, each logical channel, or each data flow (QoS flow).

[0238] Example 2: Auxiliary information is carried via PDCP Control PDU

[0239] This example 2 includes the following steps:

[0240] Step S201: The terminal determines whether a triggering condition for sending auxiliary information is met.

[0241] The triggering condition for sending the auxiliary information includes but is not limited to one of the following:

[0242] 1) Periodic triggering;

[0243] 2) Event triggering.

[0244] The period of the periodic trigger may be configured or pre-configured by the network, for example, the configured period is T. The event in the event trigger includes but is not limited to one of the following:

[0245] (1) The number of PDU Sets that are not successfully transmitted reaches a first threshold, where the first threshold can be pre-configured or network configured.

[0246] (2) Any PDU Set in the QoS flow corresponding to the terminal is not successfully transmitted, for example, the terminal discards a PDU Set.

[0247] Once the trigger condition for sending the auxiliary information is met, the terminal sends the auxiliary information to the network device, and the auxiliary information may be, but is not limited to, PDCP Control PDU. In this example, the auxiliary information is carried by PDCP Control PDU. The auxiliary information may include the first information and / or the second information described above.

[0248] Optionally, the PDCP Control PDU may carry a sequence number (SN) of a PDCP PDU that is not successfully sent by the transmitter. The PDCP PDU that is not successfully sent includes a PDCP PDU that is discarded due to a PDCP discard timer timeout and / or a PDCP PDU that is discarded due to a transmission failure due to channel quality reasons.

[0249] A format of PDCP Control PDU is as follows Figure 5 As shown. Among them, Figure 5 The meaning of each field in the PDCP Control PDU shown is as follows:

[0250] -D / C: used to indicate that the PDCP PDU is a PDCP control PDU.

[0251] -PDU type: used to indicate the type of PDCP Control PDU. For example, 100 may be used to indicate that the PDCP Control PDU is used to transmit the auxiliary information in this document.

[0252] -PDU Set tx num: used to indicate the number of PDU Sets to be sent by the transmitter within the T time period.

[0253] -PDU Set dis num: used to indicate the number of PDU Sets that the sender failed to send within the T time period.

[0254] -T: indicates the length of the statistical time period T.

[0255] -FDC: used to indicate the COUNT value or SN value of the first discarded PDCP PDU within the T time period.

[0256] -Bitmap: variable length, used to indicate whether each PDCP PDU is discarded starting from FDC.

[0257] Step S202: The terminal sends auxiliary information to the network device

[0258] In step S202, the terminal sends auxiliary information to the network device. If the auxiliary information is used to indicate the PDU Set that the terminal failed to transmit in the uplink transmission direction, the content of the auxiliary information includes but is not limited to one or more of the following:

[0259] 1) The sequence number of the PDCP PDU corresponding to the single PDU set that was not successfully transmitted (it can be the start and end sequence numbers or the sequence numbers of all PDCP PDUs)

[0260] 2) The number of PDU Sets received by the terminal from the upper layer or the number of PDU Sets to be sent by the terminal;

[0261] 3) The sequence numbers of the PDCP PDUs corresponding to the multiple PDU sets that were not successfully transmitted by the terminal.

[0262] Among them, the number of PDU Sets received by the terminal from the upper layer, the number of PDU Sets to be sent by the terminal, and the sequence numbers of PDCP PDUs corresponding to multiple PDU sets that were not successfully transmitted by the terminal can be statistical data within a period of time (for example, within a T time period).

[0263] The length of the T time period is configured or preconfigured by the network device.

[0264] The unsuccessfully transmitted PDU Set includes but is not limited to one or more of the following:

[0265] 1) PDU Set discarded by PDCP discard timer;

[0266] 2) PDU Set discarded due to transmission failure caused by channel quality reasons.

[0267] Step S203: The network device performs relevant operations based on the auxiliary information.

[0268] After receiving the auxiliary information, the network device may perform at least one of the following operations:

[0269] 1) Adjust the reordering window of the RLC entity corresponding to the PDU Set, such as updating the lower boundary of the reordering window.

[0270] 2) Calculate the PSER based on the auxiliary information.

[0271] 3) Calculating a packet error rate (PER) based on the auxiliary information.

[0272] When calculating PER, the numerator needs to subtract the number of PDUs that are discarded due to the discarding of other PDUs in the PDU Set.

[0273] The PSER is calculated based on the auxiliary information, and an example is given as follows:

[0274] Assuming that the number of PDU Sets to be sent by the terminal within the T time period included in the auxiliary information is M, and the number of PDU Sets not successfully transmitted within the T time period is N, then PSER = N / M. The statistical granularity of the PSER can be based on each bearer, each logical channel, or each QoS flow.

[0275] The PER is calculated based on the auxiliary information, as shown in the following example:

[0276] Assume that the number of PDCP PDUs to be sent by the terminal within a period of time T included in the auxiliary information is M, and the total number of PDCP PDUs discarded within the period of time is N. Among these N PDCP PDUs, the number of associated PDUs discarded when the PDU Set is discarded as a whole based on packet data unit consistency processing (PDUSet Integrated Handling, PSIHI) is P. The above N PDCP PDUs are removed from these P PDCP PDUs, so PER = (NP) / M.

[0277] Example 3: Auxiliary information is carried via UAI message and PDCP Control PDU

[0278] In this example, the auxiliary information is carried by the UAI message and the PDCP Control PDU. For example, the UAI message transmits the first sub-information in the second information described above, such as the total number of PDU Sets received by the terminal from the upper layer or required to be sent by the terminal within a period of time, and the PDCP Control PDU transmits the second sub-information in the second information described above, such as the relevant information indicating each PDU Set discarded.

[0279] This example 3 includes the following steps:

[0280] Step S301: The terminal determines whether a trigger condition for sending a UAI message is met.

[0281] The triggering condition for sending the UAI message includes periodic triggering.

[0282] The period of the periodic triggering may be configured or pre-configured by the network, for example, the configured period is T.

[0283] Once the trigger condition for periodically sending the UAI message is met, the terminal sends the first sub-information in the auxiliary information to the network device. For example, the UAI message can be used to indicate the total number of PDU Sets received by the terminal from the upper layer or required to be sent by the terminal within a period of time.

[0284] Step S302: The terminal determines whether the triggering condition for sending PDCP Control PDU is met

[0285] The triggering condition of the PDCP Control PDU includes event triggering, where the event is: at least one PDU Set is not successfully transmitted by the terminal or at least one PDU Set corresponding to a DRB specified by the terminal is not successfully transmitted, for example, the terminal discards a PDU Set.

[0286] Once the triggering condition of the PDCP Control PDU is met, the terminal sends the second sub-information in the auxiliary information to the network device. The second sub-information can be carried by, but is not limited to, the PDCP Control PDU.

[0287] Optionally, the PDCP Control PDU may also carry the SN of the PDU that the transmitter failed to send or indicate the existence of a PDU Set that failed to send. The PDU that failed to send includes the PDU discarded due to the PDCP discard timer timeout and / or the PDU discarded due to transmission failure due to channel quality reasons.

[0288] Taking the PDCP Control PDU as an example, the SN of the PDU that the sender has not successfully sent can also be carried. For example, a format of the PDCP Control PDU is as follows: Figure 6 shown. Figure 6 The meaning of each field in the PDCP Control PDU shown is as follows:

[0289] -D / C: used to indicate that the PDCP PDU is a PDCP control PDU.

[0290] -PDU type: used to indicate the type of PDCP Control PDU. For example, 100 may be used to indicate that the control PDU is used to transmit auxiliary information.

[0291] -PDU Set SN: used to indicate the SN of the PDCP Set that was not successfully sent.

[0292] -PDU Set dis num: used to indicate the number of PDU Sets that the sender failed to send within the T time period.

[0293] -T: used to indicate the statistical period or statistical time corresponding to the PDU Set SN.

[0294] -FDC: used to indicate the COUNT value or SN value of the first discarded PDU in the PDU Set identified by the PDU Set SN.

[0295] -Bitmap: variable length, used to indicate whether each PDU is discarded starting from FDC.

[0296] Step S303: The network device performs relevant operations based on the auxiliary information.

[0297] Specifically, after receiving the auxiliary information, the network device may perform at least one of the following operations:

[0298] -Adjust the reordering window of the RLC entity corresponding to the PDU Set, such as updating the lower boundary of the reordering window;

[0299] - Calculating the PSER based on the auxiliary information.

[0300] - Calculating PER based on said auxiliary information.

[0301] For example, based on the UAI message, the network device can obtain the first number of PDU Sets belonging to the target object received by the terminal from the upper layer within the most recent preset time period, or the second number of PDU Sets to be sent by the target object in the uplink transmission direction; based on the PDCP control PDU received within the most recent preset time period, the third number of PDU Sets that were not successfully transmitted by the target object in the uplink transmission direction can be counted. Then, the ratio of the third number to the first number can be determined as the PSER of the target object in the uplink transmission direction, or the ratio of the third number to the second number can be determined as the PSER of the target object in the uplink transmission direction.

[0302] For another example, when calculating PER, the numerator needs to subtract the number of PDUs that are discarded due to the discarding of other PDUs in the PDU Set.

[0303] For example, the network device receives the number M of PDU Sets to be sent by the terminal within the T time period determined by the UAI, and then determines the number N of PDU Sets that the terminal has not successfully sent within the T time period based on the PDCP Control PDU received within the T time period. Then, the PSER is calculated based on the above information, and the formula is as follows: PSER = N / M. The statistical granularity of the PSER can be based on each bearer, each logical channel, or each QoS flow.

[0304] Example 4: Report PSER directly via UAI message or PDCP Control PDU

[0305] This example 4 includes the following steps:

[0306] Step S401: The terminal determines the PSER.

[0307] The terminal calculates the PSER based on the number M of PDU Sets to be sent by the terminal within the time period T and the number N of PDU Sets that the terminal fails to send within the time period T. The calculation formula is as follows: PSER = N / M. The statistical granularity of the PSER can be based on each bearer, each logical channel, or each data flow QoS flow.

[0308] Step S402: The terminal reports the PSER to the network via UAI or PDCP Control PDU.

[0309] The network device receives the PSER reported by the terminal, thereby directly obtaining the PSER.

[0310] It can be seen from the above examples that in the embodiments of the present application, the terminal sends auxiliary information to the network device, and the auxiliary information is used to indicate the PDU Set of failed transmission of the terminal in the uplink transmission direction and / or the PSER determined by the terminal, thereby assisting the network device to adjust the reordering window and / or determine the PSER / PER.
