[0022] This disclosure provides an information processing method, a communication device, a communication system, and a storage medium.

[0023] In a first aspect, embodiments of this disclosure propose an information processing method executed by a terminal, comprising: acquiring first information, wherein the first information is used to indicate at least one reporting interval for an LCG, the reporting interval being used to indicate a value interval of a remaining time and data of the cache size corresponding to the value interval of the remaining time; and determining a reporting interval for a first type of data based on the at least one reporting interval, wherein the first type of data is data without associated discard timers.

[0024] In the above embodiments, by defining at least one reporting interval for each LCG, and based on this, determining the reporting interval for the first type of data in the LCG that is not associated with a timer, the first type of data that was not originally associated with a timer can also select a suitable reporting interval for reporting, thereby reducing the probability of these data being discarded.

[0025] In conjunction with some embodiments of the first aspect, in some embodiments, the first type of data is data that is not associated with the remaining time in the first type of DSR; the first information is the second type of DSR.

[0026] In the above embodiments, data that was not originally associated with the remaining time in the DSR can also be reported at an appropriate time, which also enhances the DSR.

[0027] In conjunction with some embodiments of the first aspect, in some embodiments, determining the reporting interval of the first type of data includes: determining the reporting interval of the first type of data based on the first remaining time of the second type of data and at least one reporting interval, wherein the second type of data is data associated with a discard timer.

[0028] In the above embodiments, a suitable reporting interval for the first type of data can be determined based on the second type of data that was originally associated with the timer and at least one reporting interval configured for an LCG. This allows the first type of data to also be reported in the reporting interval of the second type of data, facilitating subsequent operations such as simultaneous decoding of the first type of data and the second type of data, and meeting the strict time delay requirements for the first type of data and the second type of data.

[0029] In conjunction with some embodiments of the first aspect, in some embodiments, the reporting interval of the first type of data is determined based on the first remaining time of the second type of data and at least one reporting interval, including one of the following: when the first remaining time of the second type of data is in the first reporting interval of at least one reporting interval, the reporting interval of the first type of data is determined as the first reporting interval; when the first remaining time of the second type of data is in multiple second reporting intervals of at least one reporting interval, the reporting interval of the first type of data is determined as one of multiple second reporting intervals.

[0030] In the above embodiments, when the first remaining time of the second type of data falls within one of the at least one reporting intervals, the first reporting interval can be selected as the reporting interval for the first type of data, enabling the first type of data to be reported within the reporting interval for the second type of data. Alternatively, when the first remaining time of the second type of data falls within multiple of the at least one reporting intervals, one of the multiple second reporting intervals can be selected as the reporting interval for the first type of data, enabling the first type of data to be reported within the reporting interval for the second type of data. This ensures that the first type of data and the second type of data meet latency requirements when reported to the network device.

[0031] In conjunction with some embodiments of the first aspect, in some embodiments, determining the reporting interval of the first type of data as one of a plurality of second reporting intervals includes one of the following: determining the reporting interval of the first type of data as any one of a plurality of second reporting intervals; determining the reporting interval of the first type of data as the one with the smallest remaining time value range among a plurality of second reporting intervals; determining the reporting interval of the first type of data as the one with the largest remaining time value range among a plurality of second reporting intervals.

[0032] In the above embodiments, one of a plurality of second reporting intervals is selected as the reporting interval for the first type of data. This ensures that the first type of data and the second type of data can be reported to the network device while meeting latency requirements, and also adapts to more application scenarios.

[0033] In conjunction with some embodiments of the first aspect, in some embodiments, the reporting interval for the first type of data is determined based on at least one reporting interval, including one of the following: determining the reporting interval for the first type of data to be any one of the at least one reporting interval; determining the reporting interval for the first type of data to be the one with the smallest remaining time value range among the at least one reporting interval; determining the reporting interval for the first type of data to be the one with the largest remaining time value range among the at least one reporting interval.

[0034] In the above embodiments, even when the reporting interval of the first type of data is unrelated to the first remaining time of the second type of data, the first type of data, which was originally not associated with the remaining time in the DSR, can still be reported, reducing the probability of this data being discarded. Furthermore, the reporting interval of the first type of data does not necessarily fall within the reporting interval of the second type of data, making this method faster and simpler.

[0035] In conjunction with some embodiments of the first aspect, in some embodiments, determining the reporting range of the first type of data includes one of the following: determining the reporting range of the first type of data based on network device indication; or determining the reporting range of the first type of data based on protocol agreement.

[0036] The above embodiments provide multiple methods for determining the reporting range of the first type of data, which can be adapted to more application scenarios. Furthermore, the reporting range of the first type of data does not necessarily fall within the reporting range of the second type of data, making this method faster and simpler.

[0037] In conjunction with some embodiments of the first aspect, in some embodiments, the first type of data includes at least one of the following: Protocol Data Units (PDUs) of the Packet Data Convergence Protocol (PDCP) layer; and PDUs of the Radio Link Control (RLC) layer.

[0040] In conjunction with some embodiments of the second aspect, in some embodiments, at least one reporting interval is used for one of the following: when the terminal determines that the first remaining time of the second type of data is in the first reporting interval among at least one reporting interval, the terminal determines that the reporting interval of the first type of data is the first reporting interval; when the terminal determines that the first remaining time of the second type of data is in multiple second reporting intervals among at least one reporting interval, the terminal determines that the reporting interval of the first type of data is one of multiple second reporting intervals; the terminal determines that the reporting interval of the first type of data is one of at least one reporting interval.

[0041] In conjunction with some embodiments of the second aspect, in some embodiments, the first type of data includes at least one of the following: PDUs of the PDCP layer; PDUs of the RLC layer.

[0083] In some embodiments, data typically consists of multiple service flows (e.g., QoS flows) or data streams, resulting in a very large volume of traffic. XR service flows or data streams need to meet certain latency requirements during transmission, especially since some service flows or data streams need to arrive at the server simultaneously for decoding. Delay in any one service flow or data stream will cause the joint decoding of multiple service flows or data streams to fail. However, network device scheduling is dynamic. Therefore, in some cases, even if some service flows or data streams belong to low-priority logical channels, if some data packets have not been scheduled for a long time, a Buffer Status Report (BSR) needs to be sent to notify the network as soon as possible. However, currently, a BSR can only be sent when high-priority logical channel data arrives, which cannot meet the needs of emergency scheduling. Therefore, optimization for emergency scheduling in XR needs to be considered.

[0084] In some embodiments, a Delay Status Report (DSR) is introduced. The basic idea is as follows: the terminal can report a DSR, which carries delay information. For example, if uplink data has not been scheduled for a long time, the remaining time of the data packet may be less than a certain threshold. The remaining time of the data packet (or data) is the time remaining until the packet is dropped, determined by the PDCP drop timer. The DSR is set to the minimum value of data or untransmitted data in the LCG. Furthermore, the DSR carries data that requires urgent scheduling.

[0085] In some embodiments, a delay status reporting procedure is used to provide the LCG's delay status to the serving gNB. This delay status includes the remaining time, which is the minimum remaining value of the PDCP discard timer running in the PDCP SDU; these SDUs are buffered (or cached) in the LCG, but no MAC PDUs are transmitted.

[0086] In some embodiments, the format of the DSR report is shown in Figure 1B; wherein, the DSR includes: LCG field, BT field, R field, and Remaining Time and Buffer Size fields. The Remaining Time and Buffer Size fields can also be: Remaining Time field and Buffer Size field. The LCG field includes LCG0 to LCG7 fields; the BT field includes BT1, ..., BTm; the Remaining Time field includes Remaining Time 1, ..., Remaining Time m; m is an integer greater than 0.

[0087] The LCG field indicates whether to report the remaining time and cache size fields in the LCG; for example, if the LCG field value is 1, it indicates to report, or if the LCG field value is 0, it indicates not to report.

[0088] The BT field indicates which buffer size calculation table to use; for example, a BT field value of 1 indicates the use of the second buffer size calculation table, or a BT field value of 0 indicates the use of the first buffer size calculation table.

[0089] The remaining time, BT, and cache size fields of an LCG should be reported in two consecutive octets. These three fields for different LCGs should be included in the DSR MAC CE in ascending order according to LCGi; where i is an integer. Currently, for each LCG, the following three fields are reported: remaining time field, BT field, and cache size field.

[0090] The R domain is reserved space.

[0091] In some embodiments, the DSR needs to be enhanced, meaning that for an LCG, it will carry multiple or at least one set of Remaining Time and Buffer Size fields, thus introducing a second type of DSR to distinguish it from the original first type of DSR. The first type of DSR only carries one set of Remaining Time and Buffer Size fields.

[0092] The first type of DSR enhances the DSR to report multiple sets of remaining time and buffer size fields of the LCG.

[0093] For DSR, cached (or buffered) data is divided into multiple parts based on multiple reporting time thresholds configured for LCG. For each part where BS>0, DSR indicates the following information: the buffer size of the data volume in each part; and the minimum remaining time of the PDCP SDU in each part.

[0094] In some embodiments, the remaining time mentioned above is the minimum value of the remaining duration of the cached (or buffered) data. However, when performing statistics on urgent data, some data consists of higher-level control PDUs, in which case the concept of remaining duration does not exist.

[0095] For MAC delay status reporting purposes, the sending PDCP entity should consider the following delay-critical PDCP data:

[0096] The PDCP SDU was delayed, and no PDCP data PDUs were built for it;

[0097] PDCP data PDUs contain latency-critical PDCP SDUs that have not yet been committed to lower layers.

[0098] PDCP controls PDUs;

[0099] For Acknowledged Mode Data Radio Bearers (AM DRBs), PDCP SDUs need to be retransmitted;

[0100] For AM DRBs, PDCP data PDUs need to be retransmitted.

[0101] In some embodiments, the UE can be a terminal, or the terminal can be a UE.

[0102] Figure 2 is an interactive schematic diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2, the present disclosure relates to an information processing method used in an information processing system 100, the method comprising:

[0103] Step S2101: The network device sends the first information to the terminal.

[0104] In some embodiments, the terminal receives first information sent by the network device.

[0105] In some embodiments, the first information is used to indicate at least one reporting interval for an LCG, where a reporting interval indicates a range of remaining time values ​​and the corresponding buffer size data. Here, at least one reporting interval can be one or more reporting intervals; multiple reporting intervals can be two or more reporting intervals. Here, remaining time refers to the time remaining before data (or data packets) are discarded. In a specific DSR reporting format, for a reporting interval, the minimum remaining time among the buffer size data corresponding to the remaining time range and the buffer size data corresponding to the remaining time range is reported. Therefore, from the DSR reporting format, the reported minimum remaining time implicitly indicates which range of remaining time the reporting interval corresponds to.

[0106] Optionally, the reporting interval is used to indicate a range of remaining time values ​​and the corresponding cache size.

[0107] Optionally, the first information can be a second type of DSR; the second type of DSR is an enhanced DSR of the first type of DSR, and both the first and second DSRs can be DSRs. The first type of DSR carries one reporting interval for an LCG; the second type of DSR carries one or more reporting intervals for an LCG. The first type of DSR has a set of Remaining Time and Buffer Size fields for an LCG; the second type of DSR has one or more sets of Remaining Time and Buffer Size fields for an LCG.

[0108] Optionally, the first information can be used to indicate at least one reporting interval for each LCG among multiple LCGs. For example, as shown in Figure 1B, the remaining time 1 and buffer size 1 corresponding to BT1 can be modified to remainder 11 to remainder 1... i (Remaining Time 11, Remaining Time 12,...Remaining Time 1 i ), cache size 11 to cache size 1 i (Buffer Size 11, Buffer Size 12,...Buffer Size 1 i ); where i is an integer greater than 0; for 1B, the remaining time and cache size corresponding to BT 2 to BT m can be modified to one or more.

[0109] Optionally, the value range of the remaining time in the reporting interval can be replaced with a value range; this value range refers to a period of time. For example, if the remaining time is 100 milliseconds (ms), the value range can be: greater than 0 and less than or equal to 100ms (i.e., (0, 100ms]), or greater than 0 and less than or equal to 50ms (i.e., (0, 50ms]). Here, the value range can be a range of the remaining time, or a part of the range of the remaining time; or the value range can be greater than the range of the remaining time, and the maximum value of the value range is less than a certain threshold.

[0110] Optionally, a reporting interval may include a Remaining Time and Buffer Size field; or, a reporting interval may include at least a Remaining Time field, and may also include a Buffer Size field corresponding to the Remaining Time field.

[0111] Optionally, the first information may include at least one of the following: an LCG field, a BT field, and a remaining time and cache size field. Here, the LCG field and BT field included in the first information can be similar to the LCG field and BT field in the first type of DSR shown in Figure 1B, except that the remaining time and cache size fields corresponding to one LCG are modified to one or more.

[0112] Optionally, the name of the first information is not limited; it may be, for example, a second type of DSR, a reporting interval information, or a remaining time information.

[0113] In some embodiments, "domain" can be replaced with "field"; for example, the remaining time and cache size domain can refer to the remaining time and cache size field, the LCG domain can be the LCG field, the BT domain can be the BT field, etc.

[0114] In some embodiments, the name of the reporting interval indicated by the first information is not limited, and it may be, for example, a candidate interval or a candidate reporting interval.

[0115] In some alternative embodiments, the terminal determines the first information before step S2102 described below. In this case, step S2101 may be optional.

[0116] In some alternative embodiments, the terminal determining the first information may mean that the terminal determines a second type of DSR according to the instructions of the network device or the protocol; the second DSR configures one or more remaining time and cache size fields for an LCG.

[0117] Step S2102: The terminal determines the reporting range for the first type of data.

[0118] In some embodiments, the reporting interval for the first type of data may refer to the third reporting interval; the reporting interval for the second type of data may refer to the fourth reporting interval.

[0119] In some embodiments, the terminal determines a reporting interval (e.g., a third reporting interval) for the first type of data based on the first information. The reporting interval for the first type of data is used to report the first type of data within the time range represented by the reporting interval.

[0120] Optionally, the terminal determines the reporting interval (e.g., the third reporting interval) of the first type of data based on at least one reporting interval for an LCG indicated by the first information.

[0121] Optionally, the terminal determines the reporting interval for the first type of data based on at least one reporting interval for an LCG indicated by the first information. Here, the reporting interval for the first type of data may refer to the third reporting interval.

[0122] In some embodiments, the terminal determines the reporting interval (or third reporting interval) of the first type of data based on the first remaining time of the second type of data and at least one reporting interval for an LCG indicated by the first information.

[0123] Optionally, both the first type of data and the second type of data refer to the data of the aforementioned LCG.

[0124] For example, the first type of data consists of data that is not associated with a discard timer; the second type of data consists of data that is associated with a discard timer. Here, "associated" means that a remaining time has been configured for the data; "not associated" means that a remaining time has not been configured for the data. For instance, the first type of data consists of data that is not associated with the remaining time in the first DSR; the second type of data consists of data that is associated with the remaining time in the first DSR.

[0125] For example, the first type of data can be PDUs of the PDCP layer and / or PDUs of the RLC layer.

[0126] For example, the first type of data can be delay-critical data, but this first type of data is not associated with the remaining time or a timer.

[0127] For example, the second type of data could be delay-critical data, but the first type of data is associated with the remaining time or a timer.

[0128] For example, the second type of data can be data that is not transmitted in the buffer. For instance, the second type of data can be data that is buffered in the LCG but not transmitted in the MAC PDU. For instance, the second type of data can be a PDCP SDU that is buffered or cached in the LCG but has not yet been transmitted in any MAC PDU.

[0129] For example, the second type of data can be data that is not reported by the DSR. For instance, the second type of data can be data that is buffered in the LCG but not transmitted in the MAC PDU and not reported in the MAC CE. For instance, the second type of data can be a buffered or buffered PDCP SDU, but the PDCP SDU is neither transmitted in any MAC PDU nor reported in the DSR.

[0130] For example, the difference between the first type of data and the second type of data is that the first type of data is not associated with the remaining time or is not associated with a timer, while the second type of data is associated with the remaining time or is associated with a timer; other characteristics of the first type of data and the second type of data can be the same or similar.

[0131] Optionally, if the terminal determines the reporting interval of the first type of data as the first reporting interval when the first remaining time of the second type of data is in the first reporting interval of at least one reporting interval.

[0132] For example, at least one reporting interval indicated by the first information may include a first reporting interval; the first reporting interval may be one or more.

[0133] For example, the first indication information indicates at least one reporting interval for an LCG as a first reporting interval, and the first remaining time of the second type of data is in the first reporting interval; for example, the first remaining time of the second type of data is greater than 0 and less than or equal to 100ms, and the first reporting interval is the reporting interval corresponding to (0, 100ms], then the first remaining time of the second type of data is in the first reporting interval; then the terminal determines the reporting interval of the first type of data as the first reporting interval, which can be the reporting interval corresponding to (0, 100ms].

[0134] For example, the first indication information indicates at least one reporting interval for an LCG, which may be multiple, and the first remaining time of the second type of data falls within the first reporting interval among the multiple reporting intervals; for example, if the first remaining time of the second type of data is greater than 0 and less than or equal to 100ms, and the reporting intervals indicated by the first information are the reporting intervals corresponding to (0, 100ms], (100ms, 200ms], and (200ms, 300ms], then the first remaining time of the second type of data falls within the reporting interval corresponding to (0, 100ms] (at this time, the reporting interval corresponding to (0, 100ms] is the first reporting interval); then the terminal determines the reporting interval of the first type of data as the first reporting interval, which can be (0, 110ms).

[0135] For example, the name of the first reporting interval is not limited, and it may be a specified interval, etc.

[0136] Optionally, if the terminal determines that the reporting interval for the first type of data is one of the multiple second reporting intervals in the case that the first remaining time of the second type of data is in at least one reporting interval, the terminal determines that the reporting interval for the first type of data is one of the multiple second reporting intervals.

[0137] Optionally, determining the reporting interval for the first type of data as one of multiple second reporting intervals may include one of the following: determining the reporting interval for the first type of data as any one of multiple second reporting intervals; determining the reporting interval for the first type of data as the one with the smallest or second smallest remaining time value range among multiple second reporting intervals; or determining the reporting interval for the first type of data as the one with the largest or second largest remaining time value range among multiple second reporting intervals.

[0138] For example, the first indication information indicates at least one reporting interval for an LCG, which may be multiple, and the first remaining time of the second type of data may fall within multiple second reporting intervals among these multiple reporting intervals; for example, if the first remaining time of the second type of data is greater than 0 and less than or equal to 250ms, and the first information indicates reporting intervals corresponding to (0, 150ms], (150ms, 200ms], (200ms, 300ms], and (300ms, 400ms], then the first remaining time of the second type of data may fall within multiple second reporting intervals among these multiple reporting intervals; The reporting intervals corresponding to (0, 150ms], (150ms, 200ms], and (200ms, 300ms] are multiple second reporting intervals. The terminal determines that the reporting interval for the first type of data is one of the multiple second reporting intervals, which can be one of the reporting intervals corresponding to (0, 150ms], (150ms, 200ms], and (200ms, 300ms].

[0139] Based on the above embodiments, the terminal can determine that the reporting interval for the first type of data is any one of the multiple second reporting intervals, that is, any one of the reporting intervals corresponding to (0, 150ms], (150ms, 200ms], and (200ms, 300ms]. Alternatively, the terminal can determine that the reporting interval for the first type of data is the one with the smallest value range among the multiple second reporting intervals, that is, the reporting interval corresponding to (150ms, 200ms]. Alternatively, the terminal can determine that the reporting interval for the first type of data is the one with the largest value range among the multiple second reporting intervals, that is, the reporting interval corresponding to (0, 150ms].

[0140] For example, the second reporting interval can be a candidate interval; the second reporting interval that is determined to be the reporting interval of the first type of data can be a specified interval.

[0141] Optionally, the terminal determines the third reporting interval for the first type of data based on the fourth reporting interval for the second type of data.

[0142] For example, if the terminal determines that the fourth reporting interval of the second type of data is in the first reporting interval of at least one reporting interval, it determines the fourth reporting interval as the third reporting interval.

[0143] For example, if the terminal determines that the fourth reporting interval of the second type of data is in multiple second reporting intervals of at least one reporting interval, it determines any one of the multiple second reporting intervals or the one with the largest or smallest overlap with the fourth reporting interval as the third reporting interval.

[0144] Here, since the first type of data is not associated with the discard timer, there is no remaining time. In this case, the reporting interval of the first type of data is determined by the first remaining time of the second type of data, and the reporting interval of the first type of data is determined accordingly. This solves the problem that the reporting interval cannot be determined because the first type of data is not associated with the remaining time.

[0145] In some optional embodiments, determining the reporting interval of the first type of data as one of a plurality of second reporting intervals may also be: the one among the plurality of second reporting intervals with the largest overlap range with the first remaining time of the second type of data, or the one among the plurality of second reporting intervals with the smallest overlap range with the first remaining time of the second type of data.

[0146] For example, the first indication information indicates at least one reporting interval for an LCG, which may be multiple, and the first remaining time of the second type of data may fall within multiple second reporting intervals. For instance, if the first remaining time of the second type of data is greater than 20ms and less than or equal to 250ms, and the first information indicates reporting intervals corresponding to (0, 100ms], (100ms, 200ms], (200ms, 300ms], and (300ms, 400ms], then the first remaining time of the second type of data may fall within the reporting intervals of (0, 100ms], (100ms, 200ms], (200ms, 300ms], and (300ms, 400ms]. The reporting interval corresponding to [300ms] (at this time, the reporting intervals corresponding to (0,100ms], (100ms,200ms], and (200ms,300ms] are multiple second reporting intervals); then the terminal determines the reporting interval for the first type of data as: the one among the multiple second reporting intervals that has the largest overlap with the first remaining time of the second type of data, such as the reporting interval corresponding to (100,200ms]; or, the terminal determines the reporting interval for the first type of data as: the one among the multiple second reporting intervals that has the smallest overlap with the first remaining time of the second type of data, such as the reporting interval corresponding to (200ms,300ms].

[0147] In some embodiments, the terminal determines the reporting range of the first data based on at least one reporting range for an LCG indicated by the first information.

[0148] Optionally, determining the reporting interval for the first data may include one of the following: determining the reporting interval for the first type of data as any one of at least one reporting interval; determining the reporting interval for the first type of data as the one with the smallest remaining time value range among at least one reporting interval; or determining the reporting interval for the first type of data as the one with the largest remaining time value range among at least one reporting interval.

[0149] For example, if the first indication information indicates that at least one reporting interval for an LCG is multiple, and these multiple reporting intervals are the reporting intervals corresponding to (0, 150ms], (150ms, 200ms], (200ms, 300ms], and (300ms, 400ms], then the terminal determines that the reporting interval for the first type of data is one of the multiple reporting intervals, that is, it can be one of the reporting intervals corresponding to (0, 150ms], (150ms, 200ms], (200ms, 300ms], and (300ms, 400ms].

[0150] Based on the above embodiments, the terminal can determine that the reporting interval for the first type of data is any one of the multiple reporting intervals, that is, any one of the reporting intervals corresponding to (0, 150ms], (150ms, 200ms], (200ms, 300ms], and (300ms, 400ms]. Alternatively, the terminal can determine that the reporting interval for the first type of data is the one with the smallest value range among the multiple reporting intervals, that is, the reporting interval corresponding to (150ms, 200ms]. Alternatively, the terminal can determine that the reporting interval for the first type of data is the one with the largest value range among the multiple reporting intervals, that is, the reporting interval corresponding to (0, 150ms].

[0151] At this time, the reporting range of the first type of data may not fall within the reporting range of the second type of data (i.e., it is unrelated to the reporting range of the second type of data), and this method is faster and simpler.

[0152] In some embodiments, the terminal may determine the reporting range of the first type of data based on network device indications or protocol agreements.

[0153] Optionally, the terminal determines the reporting range for the first type of data based on instructions from the network device. In one optional embodiment, the method further includes: the terminal receiving second information sent by the network device, the second information indicating the reporting range for the first type of data.

[0154] For example, the second information is used to indicate one of the following: the reporting interval of the first type of data is the one with the smallest or largest remaining time value among at least one reporting interval; the reporting interval of the first type of data is any one of at least one reporting interval; the reporting interval of the first type of data is any one of a plurality of second reporting intervals; or the reporting interval of the first type of data is the one with the smallest or largest remaining time value among a plurality of second reporting intervals.

[0155] For example, the name of the second information is not limited; it may be an indication or a reporting interval indication, etc.

[0156] Optionally, the terminal determines the reporting range for the first type of data based on the protocol agreement.

[0157] For example, the agreement stipulates one of the following: the reporting interval for the first type of data is the one with the smallest or largest remaining time value among at least one reporting interval; the reporting interval for the first type of data is any one of at least one reporting interval; the reporting interval for the first type of data is any one of multiple second reporting intervals; the reporting interval for the first type of data is the one with the smallest or largest remaining time value among multiple second reporting intervals.

[0158] For example, the first indication information indicates at least one reporting interval for an LCG, which may be multiple reporting intervals, such as (0, 150ms], (150ms, 200ms], (200ms, 300ms], and (300ms, 400ms]. The terminal can determine the reporting interval for the first type of data as any one of these multiple reporting intervals according to network device instructions or protocol agreements, i.e., it can be (0, 150ms], (150ms, 200ms], (200ms, 300ms], (300ms, 400ms], etc. The reporting interval can be any one of the reporting intervals corresponding to [300ms] and (300ms, 400ms]. Alternatively, the terminal can determine the reporting interval for the first type of data to be the smallest among multiple reporting intervals, i.e., the reporting interval corresponding to (150ms, 200ms], according to network device instructions or protocol agreements. Or, the terminal can determine the reporting interval for the first type of data to be the largest among multiple reporting intervals, i.e., the reporting interval corresponding to (0, 150ms], according to network device instructions or protocol agreements.

[0159] For example, the first indication information indicates at least one reporting interval for an LCG, which may be multiple, and the first remaining time of the second type of data may fall within multiple second reporting intervals among these multiple reporting intervals; for example, if the first remaining time of the second type of data is greater than 0 and less than or equal to 250ms, and the first information indicates reporting intervals corresponding to (0, 150ms], (150ms, 200ms], (200ms, 300ms], and (300ms, 400ms], then the first remaining time of the second type of data may fall within the reporting intervals corresponding to (0, 150ms], (150ms, 200ms], and (200ms, 300ms]). The corresponding reporting interval is one of multiple second reporting intervals. The terminal can determine the reporting interval for the first type of data as any one of the multiple second reporting intervals, based on network device instructions or protocol agreements. Specifically, it can be any one of the reporting intervals corresponding to (0, 150ms], (150ms, 200ms], or (200ms, 300ms]. Alternatively, the terminal can determine the reporting interval for the first type of data as the one with the smallest value range among the multiple second reporting intervals, based on network device instructions or protocol agreements. Specifically, it can be the reporting interval corresponding to (150ms, 200ms]. Alternatively, the terminal can determine the reporting interval for the first type of data as the one with the largest value range among the multiple second reporting intervals, based on network device instructions or protocol agreements. Specifically, it can be the reporting interval corresponding to (0, 150ms].

[0160] Here, since the first type of data is not associated with the discard timer, there is no remaining time. The reporting interval for the first type of data can be determined directly through network instructions or protocol agreements, or it can be determined by combining it with the first remaining time of the second type of data. Determining the reporting interval directly through network instructions or protocol agreements is more flexible than determining it through the first remaining time of the second type of data, and it avoids the need for judgment on the second type of data, making it faster and solving the problem of not being able to determine the reporting interval for the first type of data because it has no associated remaining time.

[0161] Step S2103: The terminal sends the first type of data. Here, "send" can be replaced with "report".

[0162] In some embodiments, the network device receives a first type of data sent by the terminal.

[0163] In some embodiments, the terminal reports the first type of data within a reporting interval defined for the first type of data. Optionally, the terminal reports the first type of data within a third reporting interval.

[0164] For example, if the terminal determines that the reporting interval for the first type of data is the one with the smallest remaining time value among at least one reporting interval, then the first type of data is reported in the reporting interval with the smallest value.

[0165] For example, if the terminal determines that the reporting interval for the first type of data is the one with the largest remaining time value among at least one reporting interval, then the first type of data is reported in the reporting interval with the largest remaining time value.

[0166] For example, if the terminal determines that the reporting interval for the first type of data is any one of at least one reporting interval, then the first type of data is reported in any one of the at least one reporting intervals.

[0167] For example, if the terminal determines that the reporting interval for the first type of data is the one with the smallest remaining time value among a plurality of second reporting intervals, then the first type of data is reported in the second reporting interval with the smallest value; the plurality of second reporting intervals are the intervals in which the first remaining time of the second type of data is located.

[0168] For example, if the terminal determines that the reporting interval for the first type of data is the one with the largest remaining time value among a plurality of second reporting intervals, then the first type of data is reported in the second reporting interval with the largest remaining time value; the plurality of second reporting intervals are the intervals in which the first remaining time of the second type of data is located.

[0169] For example, if the terminal determines that the reporting interval for the first type of data is any one of a plurality of second reporting intervals, then the first type of data is reported in any one of the second reporting intervals; the plurality of second reporting intervals are the intervals in which the first remaining time of the second type of data is located.

[0170] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0171] In some embodiments, “get,” “obtain,” “receive,” “transmit,” “bidirectional transmission,” and “send and / or receive” can be used interchangeably and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining through self-processing, or autonomous implementation, among other meanings.

[0172] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transfer,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0173] In some embodiments, terms such as "certain", "preset", "default", "set", "indicated", "a certain", "any", and "first" can be used interchangeably. "Certain A", "preset A", "default A", "set A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.

[0174] In some embodiments, the determination or judgment can be made by a value represented by 1 bit (0 or 1), or by a true or false value (boolean), or by a comparison of numerical values ​​(e.g., a comparison with a predetermined value), but is not limited thereto.

[0175] The information processing method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2103. For example, step S2101 may be implemented as an independent embodiment; step S2102 may be implemented as an independent embodiment; step S2103 may be implemented as an independent embodiment; a combination of steps S2101 and S2103 may be implemented as an independent embodiment; a combination of steps S2102 and S2103 may be implemented as an independent embodiment; a combination of steps S2101 to S2103 may be implemented as an independent embodiment.

[0176] In some embodiments, step S2103 may be optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0177] In the embodiments disclosed herein, each embodiment can be implemented individually or in combination with each other, and the steps in each embodiment can be distinguished by their order.

[0178] The information processing method provided in this disclosure requires consideration of the reporting format details and the impact on the DSR triggering mechanism for the second type of DSR. This disclosure proposes a solution for triggering and reporting the second type of DSR. This disclosure relates to an information processing method, which includes:

[0179] In this embodiment of the disclosure, "class" can refer to the meaning of "category"; for example, the first type DSR and the second type DSR can be the first category DSR and the second category DSR, respectively; the first type data and the second type data can be the first category data and the second category data, respectively.

[0180] Example 1: For the first type of data, protect a scheme for statistical analysis of data reported by the second type of DSR.

[0181] In some embodiments, the second type of DSR will carry at least one set of Remaining Time and Buffer Size fields for an LCG (i.e., multiple reporting intervals).

[0182] In some embodiments, for the second type of DSR reporting, the terminal determines the value range of the remaining time according to the network configuration and / or protocol agreement, and then reports the buffer size based on the value range of the remaining time. Specifically, the network configuration and / or protocol agree on a series of DSR reporting thresholds; the terminal then classifies the buffer size according to whether the value range of the remaining time is below the threshold, thereby obtaining one or more reporting ranges.

[0183] As an example, the trigger threshold of DSR can be implicitly used as a DSR reporting threshold;

[0184] For example, if the DSR reporting threshold is z, and the network is also configured with x and y (y>x) as reporting thresholds, then a total of 3 reporting intervals are defined: interval 1, where the remaining duration is less than x; interval 2, where the remaining duration is between x and y; and interval 3, where y is between the DSR reporting threshold. That is, in this case, x, y, and z are all reporting thresholds, and the DSR trigger threshold z is the largest reporting threshold.

[0185] In some embodiments, the first type of data is delay-critical data, but it is not associated with the remaining duration, i.e., it is not associated with the discard timer; in order to distinguish it from the second type of data.

[0186] Optionally, the first type of data is the control PDU of the PDCP layer.

[0187] Optionally, the first type of data is the control PDU of the RLC layer.

[0188] In some embodiments, the second type of data is delay-critical data, but it is associated with the remaining duration, i.e., the associated discard timer, and its remaining duration is less than a threshold.

[0189] Optionally, the second type of data can be cached, untransmitted data. For example, the second type of data can be a PDCP SDU that is buffered in an LCG but has not yet been transmitted in any MAC PDU.

[0190] Optionally, the second type of data is the data that triggers DSR reporting, but it is associated with the remaining duration, and its remaining duration is less than a threshold. For example, the second type of data is: data that has neither been transmitted nor reported in previous DSRs; for example, it can be a PDCP SDU buffered by LCG, which has not been transmitted in any MAC PDU, nor reported in DSR MAC CE.

[0191] Here, the remaining duration can be the remaining time in the previous embodiment; the second type of DSR can be the first information in the previous embodiment; and the network indication can refer to the network device indication.

[0192] Example 2: For the reporting interval of the first type of data, the reporting method is determined based on the reporting interval of the second type of data. That is, for the second type of data, the remaining duration of the data is used to determine which reporting intervals it will be included in for reporting, and then the reporting interval of the first type of data is determined from these reporting intervals accordingly.

[0193] Since the first type of data is not associated with the discard timer, there is no remaining duration. Therefore, the reporting interval is determined by the remaining duration of the second type of data, and the reporting interval of the first type of data is determined accordingly. This solves the problem that the reporting interval cannot be determined because the first type of data is not associated with the remaining duration.

[0194] In some embodiments, if the second type of data is counted in a reporting interval, such as the first interval, based on its remaining duration, then the first type of data will be counted in the first interval and reported.

[0195] For example, if the remaining duration of the second type of data is lower than the threshold and belongs to reporting interval 1, then the first type of data is also reported in reporting interval 1. Here, the first interval or reporting interval 1 can be the first reporting interval in the previous embodiment.

[0196] In some embodiments, if the remaining duration of the second type of data is counted in multiple intervals (which can be called candidate intervals), such as the first interval, the second interval, etc., then the first type of data will be counted in a specified interval and reported. This specified interval can be a specified interval among the candidate intervals.

[0197] Optionally, the specified range can be agreed upon by the protocol or configured by the network.

[0198] Optionally, the specified interval can be any one of the above candidate intervals determined by the terminal according to network configuration and / or protocol agreement.

[0199] Optionally, the specified interval can be the larger or smaller one determined by the terminal from the above candidate intervals according to network configuration and / or protocol agreement. Here, the larger one refers to the one with a larger range of remaining duration values; the smaller one refers to the one with a smaller range of remaining duration values ​​or remaining duration values.

[0200] For example, if the remaining duration of the second type of data is lower than the threshold, but some of it belongs to reporting interval 1 and some belongs to reporting threshold 2: the remaining duration value range corresponding to reporting interval 2 is relatively small; for example, reporting interval 1 is the data reporting with a remaining duration of 0-xms; for example, reporting interval 1 is the data reporting with a remaining duration of x~yms, where y is greater than x.

[0201] The second category of data is placed in the candidate intervals (reporting interval 1 and reporting interval 2), and the first category of data is determined to be reported in any one of the candidate intervals; or,

[0202] The second category of data is placed in the candidate intervals (reporting interval 1 and reporting interval 2), and the first category of data is determined by the smaller range of remaining duration values ​​within the candidate intervals; that is, the data reported in reporting interval 1; or,

[0203] The second type of data is placed in the candidate intervals (reporting interval 1 and reporting interval 2), and the first type of data is determined to be reported in the candidate interval with the larger range of remaining duration values; that is, it is reported in reporting interval 2.

[0204] Here, reporting interval 1, reporting interval 2, candidate interval or designated interval can be the second reporting interval in the previous embodiment; the designated interval is one of the multiple second reporting intervals in the previous embodiment.

[0205] Example 3: For the first type of data, the specific remaining time interval within which the data is statistically analyzed is determined according to the protocol or network instructions before reporting. Here, the first type of data does not need to be reported based on the reporting interval to which the second type of data belongs.

[0206] Therefore, since the first type of data is not associated with the discard timer, there is no remaining duration. In this case, the network indicates or the reporting interval agreed upon by the protocol is reported, instead of determining the reporting interval based on the remaining duration of the second type of data and thus determining the reporting interval of the first type of data. This method is more flexible than the second embodiment and does not require a decision on the second type of data, making it faster. It solves the problem that the reporting interval cannot be determined because the first type of data is not associated with the remaining duration.

[0207] Optionally, the first type of data is reported according to the reporting interval specified by the network or the protocol. For example, if the network sets multiple candidate intervals (e.g., reporting interval 1, reporting interval 2, ..., reporting interval N; N is an integer greater than 1), the terminal can determine that the first type of data is reported in any one of the candidate intervals, or in the interval with the smallest (or smaller) or largest (or larger) value range; for example, it is reported in reporting interval 1.

[0208] Optionally, if the urgency of the scheduling is taken into account, the first type of data can be determined to be reported in the interval with the smaller remaining value range.

[0209] At this point, the second type of data is placed in the candidate interval, and the reporting interval is determined based on its remaining duration. The reporting interval for the first type of data may not necessarily fall within the reporting interval for the second type of data; this method is faster and simpler.
