[0033] In the above embodiment, the terminal determines the first time interval corresponding to the first type of data packet according to the remaining time of the first type of data packet, and determines the second time interval of the second type of data packet according to the first time interval of the first type of data packet. In this way, even for the second type of data packet with the remaining time greater than the time threshold, it can be determined in which time interval corresponding to the to-be-transmitted data packet the second type of data packet is counted, so as to facilitate the DSR reporting of the terminal to consider the data volume of the second type of data packet; so that the first type of data packet and the second type of data packet can be simultaneously scheduled by the network device.

[0034] In combination with some embodiments of the first aspect, in some embodiments, determining the second time interval corresponding to the second type of data packet according to the first time interval corresponding to the remaining time of the first type of data packet comprises one of the following:

[0035] determining the first time interval as the second time interval; the number of the first time intervals is one;

[0036] determining a third time interval in the first time interval as the second time interval; the number of the first time intervals is a plurality.

[0037] In the above embodiment, different ways are adopted to determine the second time interval in different cases where the number of the first time intervals corresponding to the first type of data packets is one or more, so as to ensure that the first type of data packets and the second type of data packets can be simultaneously scheduled by the network device for joint decoding, and in the case where the number of the first time intervals corresponding to the first type of data packets is more, a suitable third time interval can be selected from the first time intervals as the second time interval corresponding to the second type of data packets.

[0038] In some embodiments of the first aspect, the third time interval is one of the plurality of first time intervals.

[0039] In the above embodiment, the terminal can determine any one of the plurality of first time intervals as the third time interval, so as to report the second type of data packets in the time interval for DSR, thereby being able to flexibly adjust the time interval corresponding to the second type of data packets according to different network resources.

[0040] In some embodiments of the first aspect, the third time interval is a first time interval of the plurality of first time intervals that satisfies a preset condition.

[0103] Currently, in the extended reality (XR) service, data is usually composed of multiple quality of service (QoS) flows, and the traffic volume is very large. The XR service flow needs to meet certain delay requirements during transmission, especially some data flows need to arrive at the server at the same time for decoding. The delay of any one data flow will cause the joint decoding of multiple data flows to fail. However, the scheduling of the network is dynamic, so in some cases, even if some data flow belongs to a low priority logical channel, if some data packets have not been scheduled for a long time, a buffer status report (BSR) needs to be sent as soon as possible to notify the network. According to the related mechanism, only when the data of the high priority logical channel arrives can the BSR be sent, at this time, the emergency scheduling requirement cannot be met. Therefore, it is necessary to consider optimizing the emergency scheduling in XR.

[0104] In some embodiments, a DSR is introduced, and the basic idea is as follows, that is, the terminal can report a DSR, which carries delay-related information of data transmission, such as information that the uplink data has been unable to be scheduled for a long time, resulting in the remaining time of the data packet being less than a certain threshold. The remaining time of the data packet is the time to packet discard, and the remaining time is determined according to the discard timer of the packet data convergence protocol (PDCP) for example.

[0105] In some embodiments, the DSR carries data that needs to be scheduled urgently.

[0106] As shown in FIG. 1B, FIG. 1B is a format diagram of a DSR according to an exemplary embodiment. The DSR can include a logic channel group (LCG) field. The LCG field includes multiple bits, each bit corresponding to an LCG, and different bit values of the bits are used to indicate that the DSR reports the remaining time and data volume corresponding to the LCG for the LCG. If the bit value is 1, it indicates that the DSR reports the remaining time and data volume corresponding to the LCG; if the LCG field is 0, the DSR does not report the remaining time and data volume corresponding to the LCG.

[0107] The DSR also includes a BT field, an R field, a remaining time field, and a buffer size field. The BT field indicates the calculation table of the data volume used. If the BT field is 1, the second calculation table of the data volume is used; if the BT field is 1, the first calculation table of the data volume is used.

[0108] The remaining time field carries the remaining time corresponding to the LCG, and the remaining time indicates the minimum remaining value of the PDCP discard timer. The length of the remaining time field is 6 bits.

[0109] The R field is a reserved flag bit.

[0110] The buffer size field is used to indicate the data amount of the uplink delay critical data in one LCG.

[0111] By analogy, for each LCG, the DSR carries a set of remaining time field and buffer size field.

[0112] In some embodiments, the DSR needs to be enhanced, that is, for one LCG, multiple information fields can be carried to carry multiple sets of remaining time field and buffer size field, that is, the second type of DSR is introduced to distinguish from the original first type of DSR. Among them, the first type of DSR only carries a set of remaining time field and buffer size field.

[0113] In some embodiments, the terminal can determine the time interval corresponding to each information field in the second type of DSR according to, for example, network configuration, protocol agreement, etc. Then, the terminal can report the delay critical data in the corresponding time interval on each information field in the second type of DSR.

[0114] For example, the reporting threshold of the terminal performing the DSR is 6 ms. In this case, the time interval corresponding to each information field in the DSR and the data amount of the delay critical data reported by the DSR can be as follows:

[0115] The time interval corresponding to the information field 1 is 0-2 ms, and the data amount of the delay critical data counted on the information field 1 is X bits (bit). In other words, for one LCG, the delay critical data of X bits corresponds to the remaining time within 0-2 ms.

[0116] The time interval corresponding to the information field 2 is 2-4 ms, and the data amount of the delay critical data counted on the information field 2 is Y bits. In other words, for one LCG, the delay critical data of Y bits corresponds to the remaining time within 2-4 ms.

[0117] The time interval corresponding to the information field 3 is 4-6 ms, and the data amount of the delay critical data counted on the information field 3 is Z bits. In other words, for one LCG, the delay critical data of Z bits corresponds to the remaining time within 4-6 ms.

[0118] In some embodiments, the terminal can determine the remaining time threshold corresponding to each information field in the second type of DSR according to, for example, network configuration, protocol agreement, and the like. Then, the terminal can count the data volume of the uplink data whose remaining time is less than one or more remaining time thresholds, and report on the information field corresponding to each remaining time threshold.

[0119] For example, the reporting threshold of the terminal performing the DSR is 6 ms. In this case, the time interval corresponding to each information field in the DSR and the data volume of the delay-critical data reported by the DSR are as follows:

[0120] The time interval corresponding to information field 1 is 0-2 ms, and the data volume of the delay-critical data counted on information field 1 is X bits. In other words, for one LCG, the delay-critical data of X bits corresponds to a remaining time less than 2 ms.

[0121] The time interval corresponding to information field 2 is 0-4 ms, and the data volume of the delay-critical data counted on information field 2 is Y bits. In other words, for one LCG, the delay-critical data of Y bits corresponds to a remaining time less than 4 ms.

[0122] The time interval corresponding to information field 3 is 0-6 ms, and the data volume of the delay-critical data counted on information field 3 is Z bits. In other words, for one LCG, the delay-critical data of Z bits corresponds to a remaining time less than 6 ms.

[0123] In some embodiments, due to the introduction of the PDU set level discard in the DSR reporting mechanism, as long as the remaining time of one data packet in the data packet set to be transmitted is less than the time threshold of the DSR, the other data packets in the data packet set will be counted as delay-critical data, even if the remaining time of the other data packets is not less than the time threshold of the DSR. Therefore, it is necessary to consider how to count the data volume of the data packets whose remaining time is not less than the time threshold of the DSR after the introduction of the second type of DSR.

[0124] FIG. 2 is an interaction diagram I of a delay state reporting method according to an exemplary embodiment. As shown in FIG. 2, the embodiments of the present disclosure relate to a delay state reporting method for a communication system 100, and the method comprises:

[0125] Step S2101: The terminal determines a first time interval corresponding to the remaining time of a first type of data packet.

[0126] In some embodiments, the first type of data packet and the second type of data packet are included in the data packets to be transmitted on one LCG. In an embodiment, the first type of data packet and the second type of data packet are data packets belonging to the same data packet set (e.g., PDU set). Alternatively, the first type of data packet and the second type of data packet are data packets belonging to the same service. Of course, the first type of data packet and the second type of data packet can also have other association relationships, which are not limited in the embodiments of the present disclosure.

[0127] In some embodiments, the remaining time of the first type of data packet is less than or equal to the time threshold, and the remaining time of the second type of data packet is greater than the time threshold.

[0128] In some embodiments, the remaining time is the remaining time to the data packet being discarded. In some embodiments, the remaining time is the remaining time of the discard timer associated with the data packet. In an example, the remaining time can be determined according to the discard timer of the Packet Data Convergence Protocol (PDCP).

[0129] In some embodiments, the time threshold is a threshold reported by the terminal performing DSR. It can be understood that, in the case that the remaining time of the data packet to be transmitted is less than the time threshold, the terminal sends a DSR to the network device, and the DSR carries the data size of the data packet to be transmitted, so that the network device schedules the data packet to be transmitted based on the DSR.

[0130] In some embodiments, the time threshold can be predefined by a protocol, or configured by the network through signaling, or agreed by the network and the terminal in advance, which is not limited in the embodiments of the present disclosure.

[0131] In some embodiments, the name of the time threshold is not limited, which is, for example, Remaining Time Threshold, Remaining Time Threshold (RemainingTimeThreshold), etc.

[0132] In some embodiments, the first type of data packet belongs to delay critical data, and the second type of data packet associated with the first type of data packet also belongs to delay critical data. It should be noted that in the case that the first type of data packet and the second type of data packet belong to data packets of the same service, the network device needs to schedule the first type of data packet and the second type of data packet at the same time to jointly decode the first type of data packet and the second type of data packet. Therefore, when the first type of data packet belongs to delay critical data, even if the remaining time of the second type of data packet associated with the first type of data packet is greater than the time threshold, the second type of data packet can also be regarded as delay critical data. In the case that the first type of data packet and the second type of data packet are data packets of the same data packet set, since the packet dropping based on the data packet set is introduced, that is, if the dropping timer of any data packet in a data packet set is timed out (that is, the remaining time is 0), the dropping of the entire data packet set will be caused. Therefore, for a data packet set, if one data packet (that is, the first type of data packet) in the data packet set is delay critical data, then the other data packets in the data packet set are also delay critical data.

[0133] In some embodiments, the terminal can determine the first time interval corresponding to the first type of data packet according to the remaining time of the first type of data packet.

[0134] In some embodiments, the terminal can be pre-configured with multiple time intervals, and the value ranges of different time intervals are different. In an example, the terminal can determine the time interval in which the remaining time of the first type of data packet is located as the first time interval corresponding to the first type of data packet. It should be noted that the first time interval corresponding to the first type of data packet can be the first time interval corresponding to the remaining time of the first type of data packet.

[0135] In some embodiments, different time intervals can correspond to different information fields in the DSR, and the DSR is a second type of DSR. It should be noted that for one LCG, the second type of DSR includes multiple information fields, and different information fields correspond to different time intervals. In the second type of DSR, the terminal can use different information fields of the DSR to report the data amount of the to-be-transmitted data whose remaining time is in different time intervals, so that the network device can know the data amount of the to-be-transmitted data of different emergency levels.

[0136] Step S2102: The terminal determines the second time interval corresponding to the second type of data packet according to the first time interval corresponding to the first type of data packet.

[0137] In one embodiment, when the remaining time of the second type of data packet is greater than the time threshold, the terminal needs to consider not only the data amount of the first type of data packet but also the data amount of the second type of data packet associated with the first type of data packet when performing the DSR reporting. In this case, the terminal needs to determine the second time interval of the second type of data packet, so as to determine in which information field the data amount of the second type of data packet is counted when counting the data amount carried by the DSR.

[0138] In some embodiments, when the first time interval corresponding to the first type of data packet is one, the terminal determines the first time interval as the second time interval. It should be noted that, since the first type of data packet and the second type of data packet need to be scheduled by the network device at the same time for joint decoding, when the first type of data packet corresponds to only one first time interval, the first time interval can be determined as the second time interval of the second type of data packet, so that the data amount of the first type of data packet and the data amount of the second type of data packet associated with the first type of data packet can be counted in the information field corresponding to the same time interval and reported.

[0139] In an example, when the first type of data packet corresponds to time interval 1, the terminal can determine time interval 1 as the second time interval corresponding to the second type of data packet.

[0140] In some embodiments, when the first time interval corresponding to the first type of data packet is multiple, the terminal determines a third time interval in the multiple first time intervals as the second time interval. It can be understood that, when the first time interval corresponding to the first type of data packet is multiple, the terminal can determine a specified interval (i.e., the third time interval) in the multiple first time intervals as the second time interval corresponding to the second type of data packet.

[0141] In some embodiments, the third time interval can be determined according to a protocol agreement; or the third time interval can be determined according to network configuration.

[0142] In some embodiments, the third time interval is any one of the multiple first time intervals. It can be understood that the terminal can determine any one of the multiple first time intervals as the second time interval.

[0143] In some embodiments, the third time interval is the first time interval in the multiple first time intervals that satisfies a preset condition.

[0144] In some embodiments, the third time interval is the first time interval in the multiple first time intervals with the largest value range. It can be understood that, when the preset condition is that the value range of the time interval is the largest, the third time interval can be the first time interval in the multiple first time intervals with the largest value range.

[0145] For example, the multiple first time intervals of the first type of data packets are time interval 1, time interval 2 and time interval 3 respectively. The time interval 1 is 0-2 ms, the time interval 2 is 2-4 ms, and the time interval 3 is 4-6 ms. The terminal can determine the time interval 3 (i.e., the third time interval) as the second time interval.

[0146] In some embodiments, the third time interval is the first time interval with the smallest value range in the multiple first time intervals. It can be understood that, in the case that the preset condition is that the value range of the time interval is the largest, the third time interval can be the first time interval with the smallest value range in the multiple first time intervals.

[0147] For example, the multiple first time intervals of the first type of data packets are time interval 1, time interval 2 and time interval 3 respectively. The time interval 1 is 0-2 ms, the time interval 2 is 2-4 ms, and the time interval 3 is 4-6 ms. The terminal can determine the time interval 1 (i.e., the third time interval) as the second time interval.

[0148] Step S2103: The terminal counts the data amount of the delay-critical data corresponding to each time interval.

[0149] In some embodiments, before reporting the DSR, the terminal needs to determine the data amount of the delay-critical data corresponding to each time interval, so as to use the multiple information fields of the DSR to indicate the data amounts corresponding to the multiple time intervals, so that the network device can learn the data amounts of the data to be transmitted with different urgency degrees according to the DSR.

[0150] In some embodiments, the first data amount is used to indicate the data amount of the delay-critical data corresponding to the second time interval.

[0151] In some embodiments, the first data amount is determined at least by the data amount of the second type of data packets corresponding to the second time interval. It should be noted that, since the second type of data packets corresponds to the second time interval, the data amount of the second type of data packets should be counted into the data amount of the delay-critical data corresponding to the second time interval. Therefore, the terminal determines the first data amount at least according to the data amount of the second type of data packets corresponding to the second time interval.

[0152] In some embodiments, the first data amount is determined by the data amounts of the first type of data packets and the second type of data packets corresponding to the second time interval. It should be noted that, the second time interval of the second type of data packets is determined according to the first time interval of the first type of data packets, and the data packets to be transmitted corresponding to the second time interval include not only the second type of data packets but also the first type of data packets. Therefore, the terminal determines the first data amount according to the data amounts of the first type of data packets and the second type of data packets corresponding to the second time interval.

[0153] In some embodiments, when the first time interval corresponding to the first type of data packet is one, the first data amount is determined by the total data amount of the data packet set. It should be noted that if the remaining time of the first type of data packet in the data packet set is within one time interval, the time interval can be taken as the second time interval corresponding to the second type of data packet. In other words, the first type of data packet and the second type of data packet of the data packet set correspond to one time interval, and in this case, the data amount of the first type of data packet and the data amount of the second type of data packet (i.e. the total data amount of the data packet set) should be counted into the data amount of the delay critical data corresponding to the time interval.

[0154] In some embodiments, when the first time interval corresponding to the first type of data packet is multiple, the first data amount is determined by the data amount of the first type of data packet and the second type of data packet corresponding to the second time interval. It should be noted that if the remaining time of the first type of data packet in the data packet set corresponds to different first time intervals, the terminal can determine a third time interval in the multiple first time intervals as the second time interval. It can be understood that the delay critical data corresponding to the second time interval includes not only the second type of data packet, but also the first type of data packet whose remaining time is in the second time interval. In this case, the data amount of the first type of data packet and the data amount of the second type of data packet whose remaining time is in the second time interval should be counted into the data amount of the delay critical data corresponding to the second time interval.

[0155] In some embodiments, when the delay critical data corresponding to the first time interval includes only the first type of data packet, the terminal can also determine the second data amount.

[0156] In one embodiment, the second data amount is determined by the data amount of the first type of data packet corresponding to the first time interval. It should be noted that when the terminal performs DSR reporting, the terminal will report the data amount of the delay critical data corresponding to each of the multiple time intervals, so that the network device knows the data amount of the delay critical data of different urgency. When the first time interval corresponding to the first type of data packet is multiple, the terminal determines a third time interval in the multiple first time intervals as the second time interval, and counts the second type of data packet as the delay critical data corresponding to the second time interval. As for the first time interval other than the third time interval in the multiple first time intervals, the delay critical data corresponding to the first time interval includes only the first type of data packet whose remaining time is in the first time interval. In this case, the terminal determines the second data amount according to the data amount of the first type of data packet corresponding to the first time interval.

[0157] In some embodiments, the terminal determines a calculation table of the data amount of the delay critical data corresponding to each time interval.

[0158] In some embodiments, when the terminal reports the data amount of the delay critical data in each time interval on each information field in the DSR, the terminal also needs to use a calculation table of the data amount used by the terminal, so that the network device can determine the accurate value of the data amount of the delay critical data in each time interval according to the DSR.

[0159] In some embodiments, the calculation table can include a first type of table and a second type of table. The correspondence between the index and the value or value range of the data amount described by the first type of table is different from the correspondence between the index and the value or value range of the data amount described by the second type of table.

[0160] In some embodiments, the value or value range of the data amount corresponding to the same index in the first type of table and the second type of table is different. Alternatively, the number of indexes contained in the first type of table is different from the number of indexes contained in the second type of table. Here, the correspondence described by the first type of table and the second type of table in the embodiments of the present disclosure is not specifically limited.

[0161] Step S2104: The terminal determines the remaining time of the delay critical data corresponding to each time interval.

[0162] In some embodiments, when the terminal reports the delay critical data in each time interval on each information field in the DSR, the terminal not only needs to report the data amount of the delay critical data in the time interval, but also needs to report the remaining time of the delay critical data in the time interval. Considering that the delay critical data corresponding to a time interval can include multiple data packets, there are cases where the remaining times of at least two data packets in the multiple data packets are different. For example, the remaining times of the two data packets are both in the time interval, but the remaining times of the two data packets are different. For another example, the remaining time of one data packet in the two data packets is in the time interval, and the remaining time of the other data packet is not in the time interval. Therefore, before reporting the DSR, the terminal needs to determine the remaining time of each data packet in the time interval and determine the remaining time of the delay critical data in the time interval.

[0163] In some embodiments, the first remaining time is determined by the remaining times of the first type of data packet and the second type of data packet corresponding to the second time interval. It should be noted that the second time interval of the second type of data packet is determined according to the first time interval of the first type of data packet, and the delay critical data corresponding to the second time interval includes not only the second type of data packet but also the first type of data packet. Therefore, when determining the first remaining time, the terminal needs to consider the remaining times of the first type of data packet and the second type of data packet corresponding to the second time interval.

[0164] In some embodiments, the first residual time is determined by an average of the residual times of the first type data packets and the second type data packets corresponding to the second time interval.

[0165] In some embodiments, the first residual time is determined by a maximum of the residual times of the first type data packets and the second type data packets corresponding to the second time interval.

[0166] In some embodiments, the first residual time is determined by a minimum of the residual times of the first type data packets and the second type data packets corresponding to the second time interval.

[0167] In some embodiments, in a case where the delay critical data corresponding to the first time interval only includes the first type data packets, the terminal can further determine a second residual time, the second residual time being determined by the residual time of the first type data packets corresponding to the first time interval. It should be noted that when the first time interval corresponding to the first type data packets is multiple, the terminal determines a third time interval in the multiple first time intervals as the second time interval, and counts the second type data packets as the to-be-transmitted data packets corresponding to the second time interval. As for the first time intervals other than the third time interval in the multiple first time intervals, the delay critical data corresponding to the first time interval only includes the first type data packets with the residual time in the first time interval. In this case, the terminal determines the second residual time according to the residual time of the first type data packets corresponding to the first time interval.

[0168] In some embodiments, the second residual time is determined by an average of the residual times of the first type data packets corresponding to the first time interval.

[0169] In some embodiments, the second residual time is determined by a maximum of the residual times of the first type data packets corresponding to the first time interval.

[0170] In some embodiments, the second residual time is determined by a minimum of the residual times of the first type data packets corresponding to the first time interval.

[0171] Step S2105: The terminal sends a DSR to the network device.

[0172] In some embodiments, the network device receives the DSR sent by the terminal.

[0173] In some embodiments, the DSR includes multiple information fields for one LCG. It can be understood that the DSR can be a second type DSR.

[0174] In some embodiments, the first information field of the DSR includes first information, and the first information is used to indicate a first data amount. It should be noted that the first information field of the DSR corresponds to the second time interval, and the terminal transmits the DSR to indicate the data amount of the delay-critical data corresponding to the second time interval, i.e., the first data amount, by using the first information field in the DSR.

[0175] In some embodiments, the first information field of the DSR further includes second information, and the second information is used to indicate a first remaining time. It should be noted that the first information field of the DSR is not only used to indicate the data amount of the delay-critical data corresponding to the second time interval, but also used to indicate the remaining time of the delay-critical data corresponding to the second time interval. In this way, the network device can know the data amount of the data packet to be transmitted with scheduling demand and the urgency of the data packet to be transmitted with scheduling demand after receiving the DSR.

[0176] In some embodiments, the first information field of the DSR further includes third information, and the third information is used to indicate a calculation table of the first data amount. In an embodiment, the third information is used to indicate that the first data amount is determined according to a first type of table or a second type of table.

[0177] In some embodiments, the second information field of the DSR includes at least one of the following: fourth information used to indicate a second data amount, fifth information used to indicate a second remaining time, and sixth information used to indicate a calculation table of the second data amount.

[0178] In some embodiments, the DSR can include a plurality of information field pairs, and each information field pair includes a plurality of information fields, the plurality of information fields are associated with one LCG, and the plurality of information fields associated with one LCG correspond to a plurality of time intervals. The terminal can carry the first information, the second information, and the third information in the first information field associated with one LCG, and carry the fourth information, the fifth information, and the sixth information in the second information field associated with one LCG.

[0179] In an example, the first information field associated with one LCG includes a remaining time field, a buffer size field, and a BT field, the remaining time field is used to indicate a first remaining time, the buffer size field is used to indicate a first data amount, and the BT field is used to indicate a calculation table of the first data amount.

[0180] In an example, the second information field associated with one LCG includes a remaining time field, a buffer size field, and a BT field, the remaining time field is used to indicate a second remaining time, the buffer size field is used to indicate a second data amount, and the BT field is used to indicate a calculation table of the second data amount.

[0181] In some embodiments, after the network device receives the DSR sent by the terminal, the network device schedules based on the DSR. It should be noted that the network device can schedule the data packets to be transmitted by the terminal based on each information field in the DSR. Since different information fields in the DSR correspond to different time intervals, the network device can not only know the data volume of the data packets to be transmitted with scheduling needs and the different urgency levels of the data packets to be transmitted with scheduling needs, but also schedule the data packets to be transmitted with different urgency levels in batches.

[0182] In some embodiments, the term "information" can be mutually replaced with the terms "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", "data", and the like.

[0183] In some embodiments, the term "send" can be mutually replaced with the terms "transmit", "report", and the like.

[0184] The delay state reporting method related to the embodiments of the present disclosure can include at least one of steps S2101 to S2105. For example, steps S2101 to S2103 in combination with step S2105 can be implemented as an independent embodiment, but are not limited thereto.

[0185] In some embodiments, step S2104 is optional, and one or more of these steps can be omitted or replaced in different embodiments. It can be understood that the DSR can not indicate the remaining time of the delay critical data corresponding to each time interval, in which case the terminal can not determine the remaining time of the delay critical data corresponding to each time interval.

[0186] FIG. 3A is a flow diagram of a delay state reporting method according to an exemplary embodiment. As shown in FIG. 3A, the embodiments of the present disclosure relate to a delay state reporting method, which is performed by the terminal 101, and the above method includes: step S3101: determining a first time interval corresponding to the remaining time of the first type of data packet.

[0206] In some embodiments, the remaining time of the first type of data packet is less than or equal to a time threshold, and the remaining time of the second type of data packet is greater than the time threshold.

[0207] Step S5102: sending, by the terminal, a DSR to the network device.

[0208] In some embodiments, for one LCG, the DSR comprises a plurality of information fields, and the time intervals associated with different information fields are different.

[0209] In some embodiments, the first information field in the DSR comprises first information, and the first information is used to indicate a first data amount, which is determined at least by the data amount of the second type of data packet corresponding to the second time interval.

[0210] In some embodiments, the above method can comprise the methods of the above communication system side, terminal side, network device side, and the like, which will not be repeated here.

[0211] In the following, the technical solutions of the embodiments of the present disclosure are exemplarily described through specific embodiments.

[0212] Embodiment one: for the first category data, a scheme for reporting the data volume of the second category DSR is protected.

[0213] Optionally, the second category DSR will carry at least one set of remaining time and buffer size fields for one LCG. That is, for one LCG, the second category DSR has multiple reporting intervals.

[0214] Optionally, the terminal determines the value interval of the remaining time according to the network configuration and / or protocol agreement, and then reports the data volume according to the value interval of the remaining time.

[0215] Optionally, the first category data belongs to delay critical data, but its remaining time is not less than a threshold, so as to distinguish from the second category data.

[0216] Optionally, the second category data belongs to delay critical data, but its remaining time is less than a threshold.

[0217] It should be noted that the first category data corresponds to the second category data packet of the embodiments of the present disclosure. The second category data corresponds to the first category data packet of the embodiments of the present disclosure.

[0218] Embodiment two: for the first category data volume, the remaining time of the second category data belonging to the same packet set is determined to determine which specific value interval of the remaining time is reported. It can be understood that the second category data is determined in which reporting interval according to its remaining time, and then the reporting interval of the first category data is determined.

[0219] Based on this, for the first category data, the remaining time of the second category data is determined to determine which specific value interval of the remaining time is reported, which can reasonably divide the remaining time range of the first category data reported to the network, and try to consider and belong to the same time range of the second category data, so as to facilitate the base station to schedule together, which can better guarantee the correlation of the two categories of data.

[0220] Embodiment three: if the data volume of the second category data is counted in an interval, such as the first interval, according to the remaining time, the data volume of the first category data will be counted in the first interval for reporting.

[0221] In an example, the same packet set includes 1000 data packets to be transmitted, of which a part is second category data, that is, the remaining time is less than a threshold, and belongs to reporting interval 1, so the data volume of the second category data is also placed in reporting interval 1 for reporting.

[0222] In Embodiment 4, if the data quantity of the second type of data is counted in more than one interval (candidate interval), such as the first interval, the second interval, and so on, the data quantity of the first type of data is counted in a designated interval for reporting.

[0223] Optionally, the designated interval can be agreed upon by the protocol or configured by the network.

[0224] Optionally, the designated interval can be determined by the terminal from the above candidate intervals according to the network configuration and / or the protocol agreement.

[0225] Optionally, the designated interval can be determined by the terminal from the above candidate intervals according to the network configuration and / or the protocol agreement.

[0226] In an example, the same data packet set includes 1000 data packets. A part of them is the second type of data, i.e., the remaining time is less than the threshold, but some of the second type of data belongs to the reporting interval 1, and some of the second type of data belongs to the reporting interval 2.

[0227] In this case, for the first type of data, the candidate interval in which the first type of data is counted according to the remaining time of the second type of data is determined for reporting. This can reasonably divide the remaining time range of the first type of data reported to the network, try to consider the same candidate interval as the second type of data, and facilitate the base station to schedule together, so as to better guarantee the correlation of the two types of data.

[0228] As an example, the second type of data is placed in the candidate interval (i.e., the reporting interval 1 and the reporting interval 2), and the first type of data is determined to be counted in any one of the candidate intervals for reporting.

[0229] As an example, the second type of data is placed in the candidate interval (i.e., the reporting interval 1 and the reporting interval 2), and the first type of data is determined to be counted in the one with smaller value range of the candidate intervals for reporting, i.e., in the reporting interval 1 for reporting.

[0230] As an example, the second type of data is placed in the candidate interval (i.e., the reporting interval 1 and the reporting interval 2), and the first type of data is determined to be counted in the one with larger value range of the candidate intervals for reporting, i.e., in the reporting interval 2 for reporting.

[0231] As shown in FIG. 6, FIG. 6 is a diagram illustrating data volume statistics of a second type of DSR according to an exemplary embodiment. As the second type of data 612 in the data packet set 1 corresponds to one reporting interval, i.e., the remaining time 1, the data volume of the first type of data 611 in the data packet set 1 is also reported in Buffer Size 1. As the second type of data 622 in the data packet set 2 corresponds to two reporting intervals, i.e., the remaining time 1 and the remaining time 2, the data volume of the first type of data 621 in the data packet set 2 can be reported in any one of the two reporting intervals, such as the remaining time 1 (in which case the data volume of the first type of data 611 in the data packet set 1 is also reported in Buffer Size 1), or in the interval with a larger value range, such as the remaining time 2 (in which case the data volume of the first type of data 611 in the data packet set 1 is also reported in Buffer Size 2).

[0232] In an embodiment five, for each reporting interval, the terminal performs interval-based data volume statistics according to the above rules based on the remaining time of the data packets, i.e., performs attribution interval division of the data volume, but the value of the remaining time field in the second type of DSR is determined by the minimum value, the maximum value, or the average value of the remaining time of the corresponding data packets in the segment interval range.
