[0120] 3GPP defines a mechanism of reporting buffer status report (BSR) in MAC layer. The BSR contains the information of data volume in MAC entity. The Logical Channel Group (LCG) ID field indicates the LCG corresponding to the buffer status (field Buffer Size). For Long BSR format, Extended Long BSR format, Pre-emptive BSR format and Extended Pre-emptive BSR format, the LCGi field indicates whether there is buffer status (field Buffer Size) of logical channel group i in the MAC CE. When the LCGi field takes value 1, it indicates that the buffer status of logical channel group i is reported, while when the LCGi field takes value 0, it indicates that the buffer status of logical channel group i is not reported. For Long Truncated BSR format and Extended Long Truncated BSR format, the LCGi field indicates whether there is data of logical channel group i. When the LCGi field takes value 1, it indicates that there is data of logical channel group i, while when the LCGi field takes value 0, it indicates that there is no data of logical channel group i.

[0121] The Buffer Size field indicates the sum of data volume of all LCGs after the MAC PDU is generated (i.e. after the Link Control Protocol (LCP) procedure is performed). The length of Buffer Size field in Short BSR format and Short Truncated BSR format is 5 bits, while the length of Buffer Size field in other BSR formats is 8 bits. For Long BSR format, Long Truncated BSR format, Extended Long BSR format and Extended Long Truncated format, the Buffer Size fields are arranged in ascending order of LCGi.

[0122] The data volume reported in BSR is defined in Packet Data Convergence Protocol (PDCP) layer as follows: In order to report Medium Access Control (MAC) buffer status, a transmitting PDCP entity can take any of the following as PDCP data volume:

[0123] PDCP SDUs that have not constructed PDCP data Protocol Data Units (PDUs);

[0124] PDCP data PDUs that have not been submitted to lower layers;

[0125] RLC data PDUs that control PDUs;

[0126] PDCP SDUs that are retransmitted according to the relevant protocol for data radio bearers (DRBs) in acknowledged mode (AM);

[0127] PDCP data PDUs that are retransmitted according to the relevant protocol for DRBs in AM.

[0128] The definition of the amount of data reported in the BSR at the radio link control (RLC) layer includes:

[0129] To report the MAC buffer status, the terminal can take any of the following as the RLC data amount:

[0130] RLC SDUs and RLC SDU segments that have not been included in RLC data PDUs;

[0131] RLC data PDUs waiting for initial transmission;

[0132] RLC data PDUs waiting for retransmission (RLC AM).

[0133] An erasure code converts a message containing k symbols into a message containing n (n>k) symbols so that the original message can be recovered from a subset of n received symbols. The recovery algorithm already knows which of the n symbols have been received correctly. An optimal erasure code can recover the original message from any k symbols received correctly. Optimal erasure codes are maximum distance separable codes (MDS), such as Reed-Solomon codes (RS).

[0134] In application layer FEC, erasure codes can be used to improve the reliability of the system. One way is to split the original data into k equal length data packets and encode them into n (n>k) data packets using erasure codes. The n data packets are sent through different channels (e.g. through different carriers in carrier aggregation, or through different nodes in dual connectivity), which can fully utilize the diversity effect to improve reliability. At the receiving side, error detection mechanisms (e.g. through CRC) are used to obtain which data packets have been correctly received, and then the correctly received data packets are used to recover the original data. In this example, (5, 3) encoding is used, i.e. k=3, n=5. The original data is segmented into 3 data packets, the 1st data packet has symbols s1, s2, …, s m , the 2nd data packet has symbols s m+1 , s m+2 , …, s 2m , and the 3rd data packet has symbols s 2m+1 , s 2m+2 , …, s 3m . They are encoded in groups of three symbols each. In this example, it is assumed that the (5, 3) encoding used is a systematic code. Then two parity symbols need to be generated for each group of three symbols. For example, s1, s m+1 , s 2m+1 are encoded to generate parity symbols w1, w m+1 , s2, s m+2 , s 2m+2 are encoded to generate parity symbols w2, w m+2 , and so on. Thus two parity data packets are generated, containing symbols w1, w2, …, w m and symbols w m+1 , w m+2 , …, w 2m , respectively. Finally, a packet header is added to each data packet and transmitted. In this example, one symbol can be one bit or several bits, e.g. one byte. If a symbol is one byte, then the corresponding erasure code works in the finite field . If the number of symbols in the original data is not an integer multiple of k, then a suitable number of padding symbols (e.g. element 0 in the finite field corresponding to the encoding) can be added.

[0135] The above encoding method splits the original data into k equal length data packets and encodes them into n data packets using erasure codes. Another way is to encode k original data packets into n data packets using erasure codes. The two methods are similar in terms of the way erasure codes are used.

[0136] 3GPP defines a mechanism of packet discard at PDCP layer. If the network configures discardTimer for a PDCP entity, when a transmitting PDCP entity receives a PDCP SDU from upper layer, it starts a corresponding discardTimer for the PDCP SDU. If the discardTimer for a PDCP SDU expires, the transmitting PDCP entity discards the PDCP SDU and corresponding PDCP Data PDUs. If the corresponding PDCP Data PDUs have been delivered to RLC layer for processing, the PDCP indicates the discard operation to RLC layer.

[0137] 3GPP introduces several enhancements in Rel-18 XR WI. One of them is the PDU Set based QoS handling mechanism. Each PDU Set has some parameters related to QoS handling, one of which is PDU Set Importance (PSI). This parameter indicates the relative importance of a PDU Set compared to other PDU Sets in the same QoS Flow. When congestion occurs, PSI can be used for packet discard, i.e. when the network informs the UE to activate PSI based packet discard through MAC CE, the UE uses a shorter discardTimer (i.e. discardTimerForLowImportance) for PDU Sets with lower importance, so that the corresponding data packets are more likely to expire and be discarded.

[0138] In addition to PSI based packet discard, PDU Set based packet discard is introduced in Rel-18 XR. That is, when pdu-SetDiscard is configured, if a data packet is discarded, all data packets of the corresponding PDU Set are discarded.

[0139] Another enhancement is the introduction of Delay Status Report (DSR). When some data packets have not been scheduled for a long time, DSR can be sent to inform the network. The UE sends DSR through MAC CE. If the remaining time for a data packet to be discarded is less than the threshold configured by the network, the report of DSR is triggered. The DSR contains information about the remaining time and the corresponding data volume. The granularity of DSR reporting is the Logical Channel Group (LCG).

[0140] The definition of the amount of data reported in the DSR at the PDCP layer includes: in order to report the MAC delay status, the transmitting PDCP entity can determine any of the following as a Delay-critical PDCP data amount:

[0141] a Delay-critical PDCP SDU that has not constructed a PDCP data PDU;

[0142] a PDCP data PDU containing a Delay-critical PDCP SDU and has not been delivered to the lower layer yet;

[0143] a PDCP control PDU;

[0144] a PDCP SDU retransmitted according to the related protocol for AM DRBs;

[0145] a PDCP data PDU retransmitted according to the related protocol for AM DRBs.

[0146] The definition of the amount of data reported in the DSR at the RLC layer includes: in order to report the MAC delay status, the terminal can determine any of the following as a Delay-critical RLC data amount:

[0147] a Delay-critical RLC SDU and a Delay-critical RLC SDU segment that has not been contained in a RLC data PDU yet;

[0148] a RLC data PDU waiting for initial transmission containing a Delay-critical RLC SDU or a Delay-critical RLC SDU segment;

[0149] a RLC data PDU waiting for retransmission (RLC AM).

[0150] In addition, if the status PDU has been triggered and t-STATUS prohibit is not running or has expired, the UE will estimate the size of the status PDU to be transmitted in the next transmission opportunity and consider it as part of the RLC data amount for the MAC buffer status report and part of the Delay-critical RLC data amount for the MAC delay status report.

[0151] In the above embodiment, the definition of the Delay-critical PDCP SDU is: if the PDU set discard (pdu-SetDiscard) is not configured, the PDCP SDU whose remaining time to the expiration of the discardTimer is less than the remaining time threshold. If the pdu-SetDiscard is configured, the PDCP SDU belonging to a PDU set in which at least one PDCP SDU has a remaining time to the expiration of the discardTimer less than the remaining timer threshold.

[0152] When the application layer FEC is used in the uplink data transmission, the terminal can determine whether to discard the data packets of the associated application layer FEC according to the reception status of the data packets using the application layer FEC and the related threshold, i.e., only part of the data packets need to be sent. The existing BSR and DSR reporting mechanisms do not consider the case of supporting the application layer FEC, resulting in a large amount of reported data, which may cause the network to allocate too many resources, resulting in waste of wireless resources.

[0153] To solve the above problems, the present disclosure proposes an information reporting method, which proposes a method of considering the application layer FEC when the terminal reports the BSR and the DSR, thereby reporting only part of the data amount. In this method, the terminal can set the content of the BSR and the DSR report according to the information related to the FEC. This method can more accurately provide the network with the information of the BSR and the DSR, thereby reducing the waste of wireless resources. The specific content of the method is as follows.

[0154] FIG. 2 is an interaction diagram of an information reporting method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to an information reporting method for a communication system 100, which can include a terminal 101, a network device 102, and the above-mentioned method includes:

[0155] In step 2101, the terminal sends third information to the network device.

[0156] In some embodiments, the third information is used to indicate whether the terminal can determine the number of first data packets according to the first information, and / or is used to indicate whether the terminal can send the data amount of the first data packets through the second information.

[0157] In some embodiments, the first data packets are part of the second data packets, the second data packets are data packets corresponding to the third data packets at the user plane protocol stack layer of the terminal, and the third data packets are data packets generated by processing at least one original data packet using an application layer forward error correction code (FEC).

[0158] In some embodiments, for example, the number of first data packets can be the number of second data packets that need to be sent.

[0159] In other words, the third data packet is obtained by processing the original data packet using the application layer forward error correction code (FEC), and the second data packet is obtained by processing the third data packet through the protocol stack. When the terminal sends the second data packet to the network device, only part of the second data packet needs to be sent to the network device, and the network device can recover the entire data according to the received part of the data packet. At this time, the terminal can determine whether to discard the associated application layer FEC data packet according to the reception status of the application layer FEC data packet and the related threshold, that is, only part of the second data packet needs to be sent. For example, the second data packet that needs to be sent is the first data packet, that is, the number of first data packets is the number of second data packets that need to be transmitted, or the number of first data packets can be the number of second data packets that meet the delay condition.

[0160] In the above embodiment, processing the original data packet using the application layer forward error correction code (FEC) can include encoding the original data packet, for example, using (5, 3) encoding to generate 5 third data packets from 3 original data packets. For example, the above protocol stack can be an RTP-UDP-IP-SDAP-PDCP-RLC protocol stack.

[0161] In some embodiments, the user plane protocol stack layer is a packet data convergence protocol (PDCP) layer, and at least one of the first data packet, the second data packet, and the third data packet is any one of the following: a PDCP service data unit (SDU); a PDCP data PDU (PDCP Data PDU); a radio link control (RLC) service data unit (SDU); an RLC SDU segment (RLC SDU segment or RLC SDU segment); and an RLC data PDU (RLC data PDU).

[0162] In some embodiments, optionally, the RLC SDU segment can be a part of the RLC SDU.

[0163] In some embodiments, at least two data packets in the first data packet are in the same quality of service (QoS) flow, or the at least two data packets are in different QoS flows; and / or the at least two data packets are in the same data radio bearer (DRB), or the at least two data packets are in different DRBs.

[0164] In some embodiments, optionally, the second information includes at least one of the following: a buffer status report (BSR); and a delay status report (DSR).

[0165] In some embodiments, the terminal can report the terminal capability through the third information. Optionally, the terminal capability can be whether the terminal supports determining the number of the first data packets according to the first information, in other words, the terminal can report whether the terminal has the capability of adjusting the number of the reported data volume according to the first information; optionally, the terminal capability can be whether the terminal supports sending the data volume of the first data packet through the second information, in other words, the terminal can report whether the terminal has the capability of reporting the data volume to be sent, or the terminal can report whether the terminal has the capability of reporting the data volume of the data packet satisfying the delay condition. The network device can configure the terminal according to the terminal capability.

[0166] In step 2102, the network device sends the first information to the terminal.

[0167] In some embodiments, the first information includes at least one of the following:

[0168] indication information, the indication information being used to indicate whether the terminal determines the number of the first data packets;

[0169] a first ratio, the first ratio being used to indicate a ratio between the number of the at least one original data packet and the number of the third data packet;

[0170] a first number, the first number being used to indicate the number of the at least one original data packet;

[0171] a first mapping relationship, the first mapping relationship being used to determine the first ratio and / or the first number, the first mapping relationship being used to represent a mapping relationship between a parameter of the application layer FEC and the first ratio; and / or,

[0172] the first mapping relationship being used to represent a mapping relationship between the parameter of the application layer FEC and the first number, the parameter including at least one of the number of the at least one original data packet and the number of the third data packet;

[0173] a second mapping relationship, the second mapping relationship being used to determine the first ratio and / or the first number, the second mapping relationship being used to represent a mapping relationship between a PDU set importance PSI and the first ratio; and / or,

[0174] the second mapping relationship being used to represent a mapping relationship between the PDU set importance PSI and the first number.

[0175] Optionally, the first information is the indication information, that is, the network device can configure whether the terminal needs to adjust the number of the first data packets through the first information.

[0176] Optionally, the first information can be the first ratio, the first ratio can be a ratio between the number of the original data packet and the number of the third data packet, for example, when (5, 3) coding is used, the number of the original data packet is 3, the number of the third data packet is 5, and the value of the first ratio is For example, the terminal can determine the number of the first data packets according to the first ratio.

[0177] Optionally, the first information can be a first number, and the first number can be the number of the original data packets, i.e., the number of the original data packets is 3 when (5, 3) encoding is used, and the value of the first number is 3. For example, the terminal can determine the number of the first data packets according to the first number.

[0178] Optionally, the first information can be a first mapping relationship, and the first mapping relationship is used to represent the mapping relationship between the parameters of the application layer FEC and the first ratio and / or the first number. The terminal can determine the first ratio and / or the first number according to the first mapping relationship. For example, when (5, 3) encoding is used, the number of the original data packets in the parameters of the application layer FEC is 3, and the number of the third data packets is 5. Then, the first mapping relationship can be determined as: the first ratio is the ratio between the number of the original data packets and the number of the third data packets The first number is 3.

[0179] In the above embodiment, optionally, the first mapping relationship can also be a conservative mapping relationship. For example, when (5, 3) encoding is used, according to the first mapping relationship, the corresponding first ratio can be determined as The first number is 4. Since in (5, 3) encoding, the network device can restore the data when only 3 data packets are correctly received, i.e., only 3 data packets can be transmitted, and the remaining 2 data packets that are not transmitted are discarded to reduce resource waste, when the first ratio is The first number is 3, and the number of the first data packets obtained is 3, i.e., the terminal reports 3 data packets to the network device for transmission. At this time, the network device can allocate uplink transmission resources for only 3 data packets. When transmission failure occurs in the 3 data packets, the 4th resource cannot be transmitted due to no resource allocation, and the network device cannot restore the data. Therefore, a conservative mapping relationship can be used, i.e., by adjusting the corresponding relationship between the parameters and the first ratio and the first number, the number of the data packets corresponding to the data amount reported by the terminal is 4, which can improve the fault tolerance rate of data packet transmission.

[0180] Optionally, the first information can be a second mapping relationship, and the second mapping relationship is used to represent the mapping relationship between the PDU set importance PSI and the first ratio and / or the first number. The terminal can determine the first ratio and / or the first number according to the second mapping relationship.

[0181] In some embodiments, the first information is included in at least one of the following messages: a radio resource control (RRC) message; a medium access control (MAC) element; a PDCP control PDU; a radio link control (RLC) control PDU.

[0182] In other words, the first information can be carried in any of the following messages: a radio resource control (RRC) message; a medium access control (MAC) element; a PDCP control PDU; a radio link control (RLC) control PDU. The terminal can receive the first information by receiving the above-mentioned message.

[0183] In some embodiments, the first information is configured in granularity of the terminal, or the first information is configured in granularity of a DRB, or the first information is configured in granularity of a logical channel, or the first information is configured in granularity of a logical channel group, or the first information is configured in granularity of a MAC entity.

[0184] In some embodiments, this step is an optional step. When the terminal can directly determine the first information according to the parameters of the application layer FEC, the network device can not configure the first information for the terminal, and this step can be omitted.

[0185] Step 2103: The terminal determines the first information.

[0186] In some embodiments, the terminal can determine the first information according to the parameters of the application layer FEC. That is, the terminal can determine the first ratio and / or the first number according to the parameters of the application layer FEC. The method in which the terminal determines the first ratio and / or the first number according to the parameters of the application layer FEC can include:

[0187] determining the first ratio as the ratio between the number of original data packets and the number of third data packets;

[0188] determining the first number as the number of original data packets. In some embodiments, optionally, the terminal can determine the first ratio and / or the first number according to the first mapping relationship and / or the second mapping relationship.

[0189] In other words, the terminal can determine the first ratio according to the first mapping relationship and / or the second mapping relationship; and / or, determine the first number according to the first mapping relationship and / or the second mapping relationship.

[0190] In some embodiments, this step is an optional step. When the network device can configure the first information for the terminal, this step can be omitted.

[0191] Step 2104: The terminal determines the number of first data packets.

[0192] In some embodiments, the terminal can determine the number of the first data packets according to the first information, the first information being used to indicate a relevant parameter for determining the number of the first data packets.

[0193] In some embodiments, the terminal determines the number of the first data packets according to the first information includes any of the following:

[0194] determining the number of the first data packets as a product of the number of the original data packets and the first ratio;

[0195] determining the first number as the number of the first data packets.

[0196] Optionally, the number of the first data packets can be a product of the number of the original data packets and the first ratio, for example, when (5, 3) encoding is used, the number of the original data packets in the parameters of the application layer FEC is 3, the number of the third data packets is 5, and the first ratio can be a ratio between the number of the original data packets and the number of the third data packets At this time, the product of the number of the original data packets and the first ratio is That is, the number of the first data packets is 3.

[0197] Optionally, the number of the first data packets can be the first number, for example, when (5, 3) encoding is used, the number of the original data packets in the parameters of the application layer FEC is 3, that is, the first number is 3, and at this time, the number of the first data packets is 3.

[0198] In step 2105, the terminal sends second information to the network device. In some embodiments, the second information is used to indicate a data amount of the first data packets, and the data amount of the first data packets can be a size of the first data packets, for example, the data amount of the first data packets can be how many bytes the first data packets contain.

[0199] The first data packets can be data packets that need to be sent, or can be data packets that meet the delay condition, and the second information can be used to indicate data amounts of N first data packets, where N is the number of the first data packets determined by the terminal according to the first information, in other words, the terminal can report data amounts of the data packets that need to be sent through the second information, or the terminal can report the number of the data packets that meet the delay condition through the second information.

[0200] For example, when (5, 3) encoding is adopted, the network device can restore the data and realize data transmission by correctly receiving only 3 data packets, and thus the terminal can send only 3 data packets to the network device, i.e., the number of the first data packets is 3, and the terminal can report the data amount of the 3 data packets through the second information, such as the number of bytes contained in each of the 3 data packets, the remaining time information, and the like. By reducing the data amount of the 5 data packets to be reported to the data amount of the 3 data packets to be reported, wireless resource waste can be reduced.

[0201] Alternatively, a conservative strategy can be adopted, for example, for the above (5, 3) encoding, the data amount of the first data packets can be determined as 4, i.e., the terminal needs to send 4 data packets, and the terminal needs to report the data amount of the 4 data packets, so that the fault tolerance of data transmission can be improved while reducing resource waste.

[0202] The second information can include at least one of a buffer status report (BSR) and a delay status report (DSR).

[0203] Optionally, when the second information is a buffer status report, the first data packets can be data packets to be sent, and the number of the first data packets can be the number of the data packets to be sent.

[0204] Optionally, when the second information is a delay status report, the first data packets can be data packets satisfying a delay condition, where the delay condition can be that the remaining time of a data packet to be discarded is less than a threshold configured by the network, i.e., the number of the first data packets can be the number of the data packets satisfying the delay condition among the data packets to be sent. Optionally, the number of the first data packets can be the number of the data packets satisfying the delay condition among the data packets to be sent, for example, when only 3 data packets of the 5 data packets generated by (5, 3) encoding need to be sent, the number of the first data packets can be the number of the data packets satisfying the delay condition among the 3 data packets to be sent.

[0205] In the above embodiment, when the second information is a delay status report, the second information further includes the remaining time information of the first data packets.

[0206] In some embodiments, the data amount of the first data packets is included in the data amount of one or more logical channel groups (LCGs) corresponding to the first data packets, i.e., the reporting granularity of the second information is a logical channel group.

[0207] In some embodiments, optionally, the first information can be configured for a buffer status report (BSR) alone, or the first information can be configured for a delay status report (DSR) alone, or the first information can be configured for a buffer status report (BSR) and a delay status report (DSR) jointly, i.e., the buffer status report (BSR) and the delay status report (DSR) can be configured simultaneously.

[0208] The method related to the embodiments of the present disclosure can include at least one of steps 2101-2105. For example, steps 2101+2102+2103+2104+2105 can be implemented as an independent embodiment, steps 2101+2102+2104+2105 can be implemented as an independent embodiment, steps 2101+2103+2104+2105 can be implemented as an independent embodiment, and steps 2104+2105 can be implemented as an independent embodiment, but the present disclosure is not limited thereto.

[0265] The following is an exemplary introduction to the above method.

[0266] The method shown in the embodiments of the present disclosure relates to a method for enhancing data volume reporting, and the complete content of the method is as follows.

[0267] A method for sending a status report, the method comprising:

[0268] The terminal sends a status report to the network device, and the data volume indicated in the status report is adjusted according to the first information indicated by the network device, and the adjustment manner is to report part of the data volume of the associated SDU and PDU using the application layer FEC. The associated SDU and PDU using the application layer FEC refer to the SDU and PDU corresponding to a certain layer of the user plane protocol stack on the terminal side after the protocol processing of a plurality of coded data packets generated by applying the application layer FEC to one or more original data packets.

[0269] Embodiment 1: MDS code is used in the application layer, for example, (5, 3) code generates 5 data packets, and each data packet is processed by the protocol stack (RTP-UDP-IP-SDAP-PDCP-RLC) to generate PDCP SDU, PDCP Data PDU, RLC SDU, RLC SDU segment, or RLC data PDU. Assuming that 5 PDCP PDUs are generated, the 5 PDCP PDUs are associated PDU using the application layer FEC. In the protocol stack, SDAP / PDCP / RLC / MAC / PHY is the protocol stack of the 5G / NR user plane. For the 5 PDCP PDUs, the data volume can be reported according to the configuration of the first information in the status report.

[0270] In some embodiments, the SDU and PDU refer to PDCP SDU, PDCP Data PDU, RLC SDU, RLC SDU segment, RLC data PDU.

[0271] In some embodiments, the associated SDU and PDU using application layer FEC can be located in the same QoS Flow, or in different QoS Flows. Correspondingly, the associated PDU using application layer FEC can be located in the same DRB, or in different DRBs.

[0272] In some embodiments, the terminal reports the data volume of the associated SDU and PDU using application layer FEC by multiplying a proportion and including in the data volume of the corresponding LCG when reporting the status report, as in the following embodiment 2.

[0273] Embodiment 2: As in embodiment 1, (5, 3) encoding is used to generate 5 data packets, each of which is processed by the protocol stack to finally generate 5 associated SDU and PDU using application layer FEC (depending on the implementation and timing relationship, they can all be located in the PDCP layer, or all be located in the RLC layer, or part be located in the PDCP layer and the other part be located in the RLC layer). Let the proportion be 3 / 5. The terminal reports the total data volume of the 5 data packets by multiplying 3 / 5 when reporting the status report, and then includes in the data volume of the corresponding LCG.

[0274] In some embodiments, the terminal reports the data volume of the associated SDU and PDU using application layer FEC by only including the data volume of a certain number of SDU and PDU in the data volume of the corresponding LCG when reporting the status report, as in the following embodiment 3.

[0275] Embodiment 3: As in embodiment 1, (5, 3) encoding is used to generate 5 data packets, each of which is processed by the protocol stack to finally generate 5 associated SDU and PDU using application layer FEC (depending on the implementation and timing relationship, they can all be located in the PDCP layer, or all be located in the RLC layer, or part be located in the PDCP layer and the other part be located in the RLC layer). Let the certain number be 3. The terminal reports the data volume of 3 data packets of the 5 data packets in the data volume of the corresponding LCG when reporting the status report.

[0276] In some embodiments, the ratio or the specific number is obtained by a first mapping relationship, which defines a mapping from a parameter of the application layer FEC to the ratio or the specific number, i.e. the terminal selects the ratio or the specific number according to the parameter of the application layer FEC corresponding to the SDU or the PDU. The parameter of the application layer FEC includes at least one of the following: the number of data packets before the application layer FEC encoding (e.g. k in (n, k) code), the number of data packets after the application layer FEC encoding (e.g. n in (n, k) code), as shown in Embodiment 4.

[0277] Embodiment 4: Suppose (5, 3) and (6, 4) FEC encoding are used. The first mapping relationship defines a mapping from the number of data packets after the FEC encoding to the specific number. There are multiple mapping relationship configuration strategies. One strategy tends to maximize the wireless resource efficiency, and the mapping relationship can be configured as {5→3, 6→4}, i.e. corresponding to the encoding characteristics of the MDS code. This strategy assumes that the terminal has a high accuracy of the information about the reception status of the PDU using the application layer FEC. Another conservative strategy can be used, e.g. {5→4, 6→5}. This strategy can tolerate errors in the information about the reception status of the PDU using the application layer FEC obtained by the terminal to a certain extent, at the cost of reducing the wireless resource efficiency to a certain extent. Suppose the mapping relationship {5→4, 6→5} is used. If the number of data packets after the application layer FEC encoding corresponding to the SDU and the PDU is 5, the terminal includes the data amount of 3 data packets in the 5 data packets in the data amount of the corresponding LCG when reporting the BSR. If the number of data packets after the application layer FEC encoding corresponding to the PDU is 6, the terminal includes the data amount of 4 data packets in the 6 data packets in the data amount of the corresponding LCG when reporting the status report.

[0278] In some embodiments, the ratio or the specific number is obtained by a second mapping relationship, which defines a mapping from the PSI to the ratio or the specific number, i.e. the terminal selects the ratio or the specific number according to the PSI of the PDU.

[0279] In some embodiments, the status report is a buffer status report (BSR) or a delay status report (DSR).

[0280] In some embodiments, the network device configures the terminal with first information whether to adjust the data amount of the associated SDU and PDU using application layer FEC in the status report, wherein the first information is transmitted through RRC signaling, MAC CE, PDCP Control PDU or RLC Control PDU. The granularity of the configuration can be UE, DRB, Logical Channel, Logical Channel Group or MAC entity. The first information can be configured for BSR and DSR respectively, or configured jointly for BSR and DSR.

[0281] In some embodiments, the network device configures the proportion, the specific number, the first mapping relationship or the second mapping relationship with first information. The configuration itself can be used to configure the terminal whether to adjust the data amount of the associated SDU and PDU using application layer FEC in the status report.

[0282] In some embodiments, the above-mentioned proportion, specific number, first mapping relationship or second mapping relationship is directly selected by the terminal according to the parameters of the application layer FEC. One selection method is as follows:

[0283] The proportion is the ratio of the number of data packets before application layer FEC encoding to the number of data packets after encoding.

[0284] The specific number is the number of data packets before application layer FEC encoding.

[0285] The first mapping relationship or the second mapping relationship corresponds to the selection method of the above-mentioned proportion and specific number.

[0286] In some embodiments, the terminal notifies the network whether the terminal supports the method of sending the status report (i.e. the data amount indicated in the status report is adjusted according to the first information indicated by the network device) through UE capability signaling. The UE capability signaling can be transmitted in RRC signaling. The UE capability can respectively indicate whether to support the adjustment of BSR and DSR, or jointly indicate whether to support the adjustment of BSR and DSR.

[0287] In summary, the above-mentioned embodiments of the present scheme can adjust the data amount indicated in the status report, and reduce resource waste.
