[0031] The embodiments of the present disclosure provide a delay status reporting method, a communication device, a communication system, a storage medium and a program product.

[0032] In a first aspect, the embodiments of the present disclosure provide a delay status reporting method, wherein the method is performed by a terminal, and the method comprises: sending, according to a first resource, a delay status report (DSR) to a network device; the first resource is an uplink grant resource.

[0033] In the above embodiments, the terminal sends the DSR to the network device according to the current uplink grant resource (i.e., the first resource), so that the terminal can adapt to different situations of the first resource to report the delay status, and reduce the situation of reporting failure due to insufficient resources. In this way, it is beneficial for the data packets with scheduling requirements in the terminal to be timely scheduled by the network device before being discarded, thereby reducing the packet loss rate.

[0034] In some embodiments in combination with the first aspect, in some embodiments, the DSR comprises at least one of: a first type of DSR; for one logical channel group (LCG), the first type of DSR carries one information field; a second type of DSR; for one LCG, the second type of DSR can carry one or more information fields.

[0035] In the above embodiment, the DSRs can include first type DSRs and second type DSRs; and the second type DSRs can carry more information fields than the first type DSRs, and the length of the second type DSRs is greater than the length of the first type DSRs; so that the terminal can flexibly select DSRs of different lengths to report the delay status to the network device according to the resource length of the uplink grant resource.

[0036] In some embodiments of the first aspect, the sending of the delay status report (DSR) to the network device according to the first resource includes at least one of the following:

[0037] When the resource length of the first resource is greater than or equal to the resource length required for sending the second type DSR, the second type DSR is sent to the network device.

[0038] When the resource length of the first resource is less than the resource length required for sending the second type DSR, the first type DSR is sent to the network device.

[0039] When the resource length of the first resource is less than the resource length required for sending the second type DSR, the first DSR is sent to the network device; the first DSR is generated according to the second type DSR.

[0040] In the above embodiment, it is clear how to send the DSR when the resource length of the first resource is different; so that the terminal can select DSRs of different lengths and different formats according to the resource length of the first resource. The delay status information of the terminal is reported more flexibly while the first resource is fully utilized.

[0041] In some embodiments of the first aspect, when the resource length of the first resource is less than the resource length required for sending the second type DSR, the first type DSR is sent to the network device, including: when the resource length of the first resource is less than the resource length required for sending the second type DSR, and the resource length of the first resource is greater than or equal to the resource length required for sending the first type DSR, the first type DSR is sent to the network device.

[0042] In the above embodiment, when the first resource cannot carry the second type DSR but can carry the first type DSR, the terminal sends the first type DSR to the network device; so that the limited first resource is used to complete the reporting of one information field in the LCG that has an urgent scheduling requirement, and the urgent scheduling requirement is met.

[0043] In some embodiments of the first aspect, in some embodiments, the sending, to the network device, the delay status report (DSR) according to the first resource comprises: a resource length of the first resource is less than a resource length required for sending the second type of DSR, sending, to the network device, first information, the first information requesting the network device to configure a second resource for the second type of DSR; and sending the second type of DSR using the second resource.

[0044] In the above embodiments, in the case that the first resource is unable to carry the second type of DSR, the terminal can send first information to the network device to request reconfiguration of the second resource for transmitting the second type of DSR, and send the second type of DSR using the second resource. Thus, when reporting delay status information, more data with less remaining time can be reported using the second type of DSR, so that the network device can timely schedule the data, effectively reducing the packet loss rate.

[0045] In some embodiments of the first aspect, in some embodiments, a resource length of the first resource is less than a resource length required for sending the second type of DSR, and the sending, to the network device, the first DSR comprises: a resource length of the first resource is less than a resource length required for sending the second type of DSR, and the sending of the first DSR is according to a sorting result; and the first DSR comprises part of LCGs whose delay status information is to be sent.

[0046] In the above embodiments, in the case that the first resource is unable to carry the second type of DSR, the terminal can select part of LCGs from the delay status information to be sent according to the sorting result, to complete the delay status reporting of the selected part of LCGs using the first DSR, so that the network device can complete the emergency scheduling based on the first DSR.

[0047] In some embodiments of the first aspect, in some embodiments, the sorting result comprises at least one of: a priority sorting of the LCGs; and an identification (ID) of the LCGs.

[0048] In the above embodiments, the sorting result of the plurality of LCGs can be determined based on the priority sorting of the LCGs, and / or can be determined based on the ID sequence of the LCGs. In this way, how to select part of LCGs carried by the first DSR in the case that the first resource is unable to carry the second type of DSR is clear.

[0049] In some embodiments of the first aspect, in some embodiments, the method further comprises at least one of:

[0050] determining a first sorting sequence of the plurality of LCGs based on a priority of the LCGs;

[0051] in the case that the first sorting sequence of the plurality of LCGs is same, determining the sorting result according to an identification (ID) of the plurality of LCGs.

[0052] In the above embodiment, in the case that the first resource is unable to carry the second type of DSR, the first order of the plurality of LCGs is determined according to the priorities of the plurality of LCGs; and in the case that the first order of the plurality of LCGs is the same, the order of the plurality of LCGs is determined according to the IDs of the plurality of LCGs; in this way, the first DSR can report the delay state information of the LCGs with higher emergency degree in priority.

[0053] In some embodiments of the first aspect, the method further comprises: determining the priority of the LCG according to the priorities of LCs included in the LCG.

[0054] In the above embodiment, considering that the LCG includes a plurality of LCs and the remaining time lengths of the data packets to be scheduled in different LCs are different, the terminal can determine the priority of the LCG according to the priorities of the plurality of LCs included in the LCG, so as to report the delay state of the LCG with urgent scheduling demand through the first DSR in the case of selecting the delay state information of the part of LCGs carried by the first DSR based on the priority order.

[0055] In some embodiments of the first aspect, the determining the priority of the LCG according to the priorities of LCs included in the LCG comprises at least one of:

[0056] determining the priority of the LCG according to the priorities of the LCs in the LCG;

[0057] determining the priority of the LCG according to the priority of the LC with the first type of data in the LCG, the remaining time length of the first type of data being less than the time length threshold.

[0058] In the above embodiment, two ways of determining the priority of the LCG are provided, the first way is to determine the priority of the LCG based on the priorities of all LCs in the LCG, and the second way is to determine the priority of the LCG based on the priority of the LC with urgent scheduling demand in the LCG. In this way, the determination way of the priority can be flexibly selected.

[0059] In some embodiments of the first aspect, the sending the first DSR according to the order comprises:

[0060] selecting at least one first LCG from the plurality of LCGs whose delay state information is to be sent according to the first resource; the order of any first LCG is higher than the order of any second LCG, the second LCG being an LCG other than the first LCG in the plurality of LCGs;

[0061] The first DSR is sent, and the first DSR includes one or more information fields of the first LCG.

[0062] In the above embodiment, in the case that the first resource is unable to carry the second type of DSR, at least one first LCG in the front according to the sorting result is selected, and all information fields of the first LCG in the front are reported by using the first DSR, so that the information fields of the first LCG needing to be urgently scheduled are reported by using the first DSR, and the demand of urgent scheduling is met.

[0063] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: for the second LCG, abandoning sending a DSR on the first resource.

[0064] In the above embodiment, in the case that the first resource is unable to carry the second type of DSR, the delay state information of the second LCG in the back can be abandoned to be reported by using the first resource, so as to ensure that the delay state information of the first LCG having the urgent scheduling demand can be timely reported to the network device.

[0065] In combination with some embodiments of the first aspect, in some embodiments, the first DSR carries part of the information fields of the second LCG.

[0066] In the above embodiment, for the second LCG in the back, part of the information fields of the second LCG can be carried by using the first DSR, so that the reporting of all the information fields of the first LCG in the front and part of the information fields of the second LCG in the back is completed by using the first DSR. Therefore, more data having the scheduling demand is reported by using the first DSR, and the number of information interactions between the terminal and the network device is reduced.

[0067] In combination with some embodiments of the first aspect, in some embodiments, the first DSR carries one information field of the second LCG; or the first DSR carries one or M information fields of the second LCG; the M is less than N; and the N is the maximum number of information fields of one LCG.

[0068] In the above embodiment, for the second LCG in the back, the first DSR can carry one information field of the second LCG, so that the delay state of the data needing to be urgently scheduled in the second LCG is reported by using the first DSR, and the demand of urgent scheduling is met. Or, for the second LCG in the back, the first DSR can carry at least one information field of the second LCG, so that the remaining resource length of the first DSR is fully utilized to carry the information field of the second LCG, so as to realize the reporting of the delay state of more data needing to be scheduled in the second LCG.

[0069] In some embodiments of the first aspect, in some embodiments, the second type of DSR carries first identification information; the first DSR carries second identification information, the first identification information and the second identification information are different.

[0070] In the above embodiments, by introducing different identification information for the second type of DSR and the first DSR, the network device can identify the format of the received DSR according to the identification information carried in the DSR, so that the network device can effectively decode the information content carried in the DSR.

[0071] In some embodiments of the first aspect, in some embodiments, the method further comprises:

[0072] sending second information to the network device, the second information being used to indicate at least one of the following: whether the terminal supports sending the second type of DSR; whether the terminal supports sending the first DSR.

[0073] In the above embodiments, the terminal can inform the network device of the delay state reporting capability supported by the terminal by sending the second information to the network device, so as to enable the network device to configure the terminal with uplink grant resources of a corresponding length.

[0074] In some embodiments of the first aspect, in some embodiments, the method further comprises one of the following:

[0075] determining the maximum number of information fields that can be carried by one LCG in the second type of DSR according to a protocol agreement;

[0076] determining the maximum number of information fields that can be carried by one LCG in the second type of DSR according to third information sent by the network device.

[0077] In the above embodiments, the maximum number of information fields that can be carried by one LCG in the second type of DSR can be agreed by a protocol or configured by the network device. In this way, the terminal and the network device reach an agreement on the number of information fields that can be carried by one LCG in the second type of DSR, thereby facilitating the network device to correctly decode the second type of DSR sent by the terminal.

[0124] 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 the effective data packet has 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 high priority logical channel data 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.

[0125] In some embodiments, a DSR report 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, causing the remaining time of the data packet to be 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.

[0126] In some embodiments, the DSR carries data that needs to be scheduled urgently.

[0127] As shown in FIG. 1B, FIG. 1B is a format diagram of a DSR according to an exemplary embodiment. The DSR includes a logic channel group (LCG) field, wherein the LCG field includes multiple bits, each bit corresponding to an LCG; different bit values of the bits are used to indicate whether the DSR includes the remaining time and data volume corresponding to the LCG for the LCG; if the bit value is 1, it indicates that the DSR includes the remaining time and data volume corresponding to the LCG; if the LCG field is 0, the DSR does not include the remaining time and data volume corresponding to the LCG.

[0128] The DSR also includes a remaining time field, which carries the remaining time corresponding to the LCG, and the remaining time indicates the minimum remaining value of the PDCP discard timer; wherein the length of the remaining time field is 6 bits.

[0129] The DSR further includes a BT field, which is used to indicate which data volume calculation table is used; if the BT field is 1, it indicates that the second data volume calculation table is used; if the BT field is 0, it indicates that the first data volume calculation table is used.

[0130] In the related mechanism, for each LCG, the information field of the DSR carries the residual duration, the data volume (buffer size) and the BT. 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 residual duration and data volume, that is, a second type of DSR is introduced to distinguish from the original first type of DSR.

[0131] It can be understood that, since the second type of DSR is longer, a larger first resource is needed to carry the second type of DSR, and therefore, the problem of how to send the DSR in the case of insufficient first resource needs to be considered.

[0132] FIG. 2 is an interaction diagram I of a delay state reporting method according to an exemplary embodiment. As shown in FIG. 2, the present disclosure relates to a delay state reporting method, which is used in a communication system 100, and the method includes the following steps.

[0133] In step S2101, the terminal sends a DSR to the network device.

[0134] In some embodiments, the network device receives the DSR sent by the terminal.

[0135] In some embodiments, the terminal sends the DSR to the network device according to the first resource.

[0136] In some embodiments, the first resource is an uplink grant resource.

[0137] In some embodiments, the DSR includes at least one of the following: a first type of DSR; for one LCG, the first type of DSR carries one information field; a second type of DSR; for one LCG, the second type of DSR can carry one or more information fields.

[0138] It should be noted that, in the first type of DSR, one LCG corresponds to one information field, which is used to carry the delay state information of a first data of the LCG. In the second type of DSR, one LCG corresponds to one or more information fields, which are used to carry at least one delay state information of the LCG.

[0139] In some embodiments, the delay state information can include at least one of the following: the residual duration of the data to be transmitted; the data volume of the data to be transmitted.

[0140] In some embodiments, the residual duration corresponding to the data to be transmitted is the residual duration from the data to be transmitted being discarded.

[0141] In some embodiments, the remaining time length corresponding to the data to be transmitted is a remaining time length of a discard timer associated with the data to be transmitted.

[0142] It can be understood that, compared with the first type of DSR, the second type of DSR carries more information, so that the length of the second type of DSR is longer, and the resource length of the uplink grant resource required for transmitting the second type of DSR is longer. Therefore, before transmitting the DSR, the terminal needs to consider whether the uplink grant resource can carry the second type of DSR, and how to transmit the DSR in the case that the uplink grant resource is not enough.

[0143] In some embodiments, the terminal transmits the DSR to the network device according to the first resource, including:

[0144] The resource length of the first resource is less than the resource length required for transmitting the second type of DSR, the first information is transmitted to the network device, and the first information requests the network device to configure the second resource for the second type of resource;

[0145] The second type of DSR is transmitted using the second resource.

[0146] It should be noted that, in the case that the resource length of the first resource is less than the resource length required for transmitting the second type of DSR, the terminal transmits the first information to the network device to request the network device to reconfigure the second resource for transmitting the second type of DSR. The terminal transmits the second type of DSR to the network device using the second resource reconfigured by the network device.

[0147] In some embodiments, the first information is a scheduling request (SR).

[0148] In some embodiments, the terminal transmits the DSR to the network device according to the first resource, including at least one of the following:

[0149] The resource length of the first resource is greater than or equal to the resource length required for transmitting the second type of DSR, and the second type of DSR is transmitted to the network device;

[0150] The resource length of the first resource is less than the resource length required for transmitting the second type of DSR, and the first type of DSR is transmitted to the network device;

[0151] The resource length of the first resource is less than the resource length required for transmitting the second type of DSR, and the first DSR is transmitted to the network device; the first DSR is generated according to the second type of DSR.

[0152] It should be noted that, in the case that the resource length of the first resource is greater than or equal to the resource length required for transmitting the second type of DSR, i.e., the first resource can carry the second type of DSR, the terminal can transmit the second type of DSR to the network device.

[0153] In a case where the resource length of the first resource is less than the resource length required for sending the second type of DSR, i.e., the first resource cannot carry the second type of DSR, the terminal can send the first type of DSR to the network device. It can be understood that, since the resource length of the first type of DSR is less than the resource length required for sending the second type of DSR, in a case where the first resource cannot carry the second type of DSR, the first type of DSR can be sent by using the first resource.

[0154] In a case where the resource length of the first resource is less than the resource length required for sending the second type of DSR, i.e., the first resource cannot carry the second type of DSR, the terminal can send the first type of DSR to the network device. It can be understood that, since the resource length of the first type of DSR is less than the resource length required for sending the second type of DSR, in a case where the first resource cannot carry the second type of DSR, the first type of DSR can be sent by using the first resource.

[0155] In some embodiments, the first type of DSR is obtained by performing a truncation operation on the second type of DSR.

[0156] It should be noted that the truncation operation based on the second type of DSR can be understood as truncating from the last LCG in the second type of DSR to the front according to the order of the plurality of LCGs in the second type of DSR.

[0157] In some embodiments, the first type of DSR is obtained by performing a puncturing operation on the second type of DSR.

[0158] It should be noted that the puncturing operation based on the second type of DSR can be understood as marking part of the plurality of LCGs of the second type of DSR, and removing the marked LCGs from the plurality of LCGs of the second type of DSR.

[0159] In some embodiments, in a case where the resource length of the first resource is less than the resource length required for sending the second type of DSR, sending the first type of DSR to the network device comprises: in a case where the resource length of the first resource is less than the resource length required for sending the second type of DSR, and the resource length of the first resource is greater than or equal to the resource length required for sending the first type of DSR, sending the first type of DSR to the network device.

[0160] In a case where the resource length of the first resource is less than the resource length required for sending the second type of DSR, it is further necessary to determine the size relationship between the resource length of the first resource and the resource length required for sending the first type of DSR, to determine whether the first resource can carry the first type of DSR.

[0161] In a case where it is determined that the resource length of the first resource is greater than or equal to the resource length required for sending the first type of DSR, the terminal sends the first type of DSR to the network device.

[0162] In some embodiments, the method further comprises: when the resource length of the first resource is less than the resource length required for transmitting the first type of DSR, sending first information to the network device; the first information requests the network device to configure a second resource for the second type of resource; and transmitting the second type of DSR using the second resource.

[0163] It should be noted that when it is determined that the resource length of the first resource is less than the resource length required for transmitting the second type of DSR, and the resource length of the first resource is less than the resource length required for transmitting the first type of DSR, the terminal can send first information to the network device to request uplink grant resources for transmitting the second type of DSR; and transmit the second type of DSR using the uplink grant resources configured by the network device based on the first information.

[0164] In some embodiments, when the resource length of the first resource is less than the resource length required for transmitting the second type of DSR, sending the first DSR to the network device comprises: when the resource length of the first resource is less than the resource length required for transmitting the second type of DSR, transmitting the first DSR according to the sorting result; and the first DSR comprises part of the LCGs whose delay state information is to be transmitted.

[0165] It should be noted that when the resource length of the first resource is less than the resource length required for transmitting the second type of DSR, part of the LCGs whose delay state information is to be transmitted can be selected from all the LCGs of the second type of DSR according to the sorting result to generate the first DSR; and the first DSR is transmitted.

[0166] It can be understood that since the first DSR comprises part of the LCGs whose delay state information is to be transmitted, the length of the first DSR is shorter than that of the second type of DSR; therefore, when the resource length of the first resource is less than the resource length required for transmitting the second type of DSR, the first DSR with shorter length can be transmitted. It should be noted that the number of the selected part of the LCGs can be determined according to the resource length of the first resource; so as to meet the size limit of the first resource.

[0167] In some embodiments, the sorting result comprises at least one of the following: priority sorting of the LCGs; and identification ID of the LCGs.

[0168] It should be noted that in the process of generating the first DSR, the sorting result of all the LCGs whose delay state information is to be transmitted can be determined according to the priority of the LCGs.

[0169] In some embodiments, the priority of the LCGs can be determined according to the urgency of the data to be transmitted by the LCGs. For example, the priority of the LCGs can be determined according to the remaining time length of the data to be transmitted by the LCGs.

[0170] In some embodiments, the priority of the LCGs can be determined according to the importance of the data to be transmitted by the LCGs.

[0171] In some embodiments, to simplify the generation process of the first DSR, the ranking results of all the LCGs in the delay status information to be sent can be determined according to the IDs of the LCGs.

[0172] In some embodiments, the ranking results of the LCGs can be determined according to the priority ranking of the LCGs and the IDs of the LCGs.

[0173] In some embodiments, the method further comprises at least one of the following: determining a first ranking order of the plurality of LCGs based on the priorities of the LCGs; and determining the ranking results of the plurality of LCGs according to the IDs of the plurality of LCGs in the case that the first ranking order of the plurality of LCGs is the same.

[0174] It should be noted that, when determining the ranking results of the plurality of LCGs, the ranking results are determined based on the priorities of the plurality of LCGs first.

[0175] The first ranking order can be a ranking order of the priorities of the plurality of LCGs from high to low, or the first ranking order can be a ranking order of the priorities of the plurality of LCGs from low to high.

[0176] In some embodiments, the first ranking order of the plurality of LCGs can be determined according to the priorities of the LCGs first. Considering that there can be LCGs with the same priority in the plurality of LCGs, to determine the ranking results of the LCGs with the same priority, a second ranking order of the plurality of LCGs with the same first ranking order can be determined based on the IDs of the plurality of LCGs with the same first ranking order; and the ranking results of the plurality of LCGs can be determined.

[0177] Here, the second ranking order can be a ranking order of the IDs of the plurality of LCGs from large to small; or the second ranking order can be a ranking order of the IDs of the plurality of LCGs from small to large.

[0178] In some embodiments, the method further comprises determining the priority of the LCG according to the priority of the LC included in the LCG.

[0179] It should be noted that, the LCG includes a plurality of LCs, and each LC has a corresponding priority. The priority of the LCG can be determined according to the priority of the LC included in the LCG.

[0180] In some embodiments, the priority of the LCG can be determined according to the priority of the LC with the highest priority included in the LCG.

[0181] In some embodiments, determining the priority of the LCG according to the priorities of the LCs included in the LCG comprises at least one of: determining the priority of the LCG according to the priorities of the LCs in the LCG; determining the priority of the LCG according to the priorities of the LCs in the LCG that have the first type of data; and the remaining time duration of the first type of data is less than a time duration threshold.

[0182] Here, the time duration threshold can be a threshold of the remaining time duration configured to trigger the DSR of the LCG.

[0183] In some embodiments, the time duration threshold can be configured by the network.

[0184] In some embodiments, the time duration threshold can be agreed by the protocol.

[0185] It should be noted that the LCG includes a plurality of LCs, and each LC has data to be transmitted. According to the remaining time duration of the data to be transmitted by each LC, the LCs having the first type of data are selected; and the remaining time duration of the first type of data is less than the time duration threshold. It can be understood that the LC having the first type of data indicates that the LC has an urgent scheduling requirement.

[0186] The priority of the LCG is determined according to the priorities of the LCs in the LCG. It can be understood that the priority of the LCG is determined according to the priorities of all the LCs in the LCG (including the LCs having the urgent scheduling requirement and the LCs not having the urgent scheduling requirement).

[0187] The priority of the LCG is determined according to the priorities of the LCs in the LCG that have the first type of data. It can be understood that the priority of the LCG is determined according to the priorities of the LCs in the LCG having the urgent scheduling requirement.

[0188] In some embodiments, sending the first DSR according to the sorting result comprises:

[0189] Selecting at least one first LCG from the plurality of LCGs whose delay state information is to be transmitted according to the first resource; the sorting order of any first LCG is higher than the sorting order of any second LCG, and the second LCG is an LCG other than the first LCG in the plurality of LCGs;

[0190] Sending the first DSR, and the first DSR includes one or more information fields of the first LCG.

[0191] Exemplarily, for one LCG, the number of information fields included in the first DSR is the same as the number of information fields of the second type of DSR for one LCG. And / or, for one LCG, the time interval corresponding to the information fields of the first DSR is the same as the time interval corresponding to the information fields of the second type of DSR.

[0192] It can be understood that the first LCG is an LCG with a higher rank in the plurality of LCGs, and the second LCG is an LCG with a lower rank in the plurality of LCGs.

[0193] At least one first LCG can be selected from the plurality of LCGs whose delay status information is to be sent, according to a resource length of the first resource. It should be noted that the number of selected first LCGs is determined by the resource length of the first resource. The resource length of the first resource is greater than or equal to a resource length required for sending each information field of the at least one first LCG.

[0194] A first DSR is generated based on each information field of the first LCG in the delay status information to be sent, and the first DSR is sent using the first resource. Here, the first DSR includes at least each information field of the first LCG.

[0195] It should be noted that, for the LCG with a higher rank (i.e., the first LCG), the first DSR carries all information fields of the first LCG. The maximum number of information fields of the first LCG carried in the first DSR is the same as the maximum number of information fields of an LCG carried in the second type of DSR.

[0196] In some embodiments, the method further includes, for the second LCG, abandoning sending a DSR on the first resource.

[0197] In the embodiments of the present disclosure, since the remaining resource length of the first resource is less than a resource length required for sending the second LCG, the delay status information of the second LCG can not be sent on the first resource.

[0198] It can be understood that, in the case where the resource length of the first resource is less than a resource length required for sending the second type of LCG, a first DSR can be generated based on each information field of the first LCG in the delay status information to be sent, so as to send the first DSR using the first resource, thereby completing reporting of the delay status information of the first LCG with a higher rank. For the second LCG with a lower rank, a DSR can be abandoned on the first resource.

[0199] For example, the second type of LCG carries 3 information fields of LCG1 and 3 information fields of LCG2; in the case where the resource length of the first resource is less than a resource length required for sending the second type of LCG, a rank result of LCG1 and LCG2 can be determined, if LCG1 has a higher rank and LCG2 has a lower rank, the first DSR can carry 3 information fields of LCG1; and for the 3 information fields of LCG2, reporting is not performed in the first DSR.

[0200] In some embodiments, the first DSR carries part of the information fields of the second LCG.

[0201] In order to fully utilize the first resource, in a case where the resource length of the first resource is greater than the resource length required for transmitting each information field of the first LCG, the first DSR can further carry part of the information fields of the second LCG.

[0202] It can be understood that, from each information field of the second LCG in the delay status information to be transmitted, one information field of the second LCG can be selected, so as to generate the first DSR based on each information field of the first LCG and the one information field of the second LCG.

[0203] In some embodiments, the first DSR carries one information field of the second LCG; or the first DSR carries one or M information fields of the second LCG.

[0204] Here, M is less than N, and N is the maximum number of information fields of one LCG.

[0205] In the embodiments of the present disclosure, the first DSR carries one information field of the second LCG. It can be understood that, for the second LCG sorted later, the delay status information of the second LCG can be transmitted on the first resource, but the reporting of the delay status information of the second LCG falls back to the format of the first type of DSR. That is, one information field of each second LCG is included in the first DSR.

[0206] It can be understood that, from each information field of the second LCG in the delay status information to be transmitted, one information field of the second LCG can be selected, so as to generate the first DSR based on each information field of the first LCG and the one information field of the second LCG.

[0207] It is worth noting that the number of information fields of the first LCG carried in the first DSR is the same as the number of information fields of the LCG carried in the second type of DSR; and the number of information fields of the second LCG carried in the first DSR is the same as the number of information fields of the LCG carried in the first type of DSR.

[0208] For example, the delay status information to be transmitted includes 3 information fields of LCG1 and 3 information fields of LCG2; in a case where the resource length of the first resource is less than the resource length required for transmitting the second type of LCG, the sorting result of LCG1 and LCG2 can be determined, if LCG1 is sorted first and LCG2 is sorted later, the first DSR can carry 3 information fields of LCG1 and 1 information field of LCG1.

[0209] Or, the first DSR can carry one or M information fields of the second LCG. It can be understood that, for the second LCG sorted later, the delay status information of the second LCG can be transmitted on the first resource, but all information fields of the second LCG cannot be transmitted, only part of the information fields of the second LCG can be transmitted until the first resource is used up.

[0210] It can be understood that the remaining resource length of the first resource can be determined according to the resource length of the first resource and the resource length required for transmitting each information field of the first LCG; and part of the information fields are selected from the plurality of information fields of each second LCG according to the remaining resource length of the first resource, so that the remaining resource length of the first resource is equal to the resource length required for transmitting the selected part of the information fields of the second LCG. Thus, the first DSR is generated based on each information field of the first LCG and the selected part of the information fields of the second LCG.

[0211] For example, the delay status information to be transmitted includes 3 information fields of LCG1 and 3 information fields of LCG2; in the case that the resource length of the first resource is less than the resource length required for transmitting the second type of LCG, the sorting result of LCG1 and LCG2 can be determined, if LCG1 is sorted first and LCG2 is sorted last, and the resource length of the first resource is only enough to transmit 5 information fields, the first DSR can carry 3 information fields of LCG1 and 2 information fields of LCG1.

[0212] In some embodiments, the second type of DSR carries first identification information; the first DSR carries second identification information; the first identification information is different from the second identification information.

[0213] It should be noted that, in order to facilitate the network device to distinguish the received second type of DSR and the first DSR, the terminal can carry the first identification information in the second type of DSR and carry the second identification information in the first DSR; thus, the second type of DSR and the first DSR are distinguished by using different first identification information and second identification information.

[0214] In some embodiments, the method further includes: transmitting a Medium Access Control (MAC) Control Element (CE) to the network device, the MAC CE including the DSR.

[0215] In some embodiments, the method further includes: transmitting second information to the network device, the second information being used to indicate at least one of the following: whether the terminal supports transmitting the second type of DSR; whether the terminal supports transmitting the first DSR.

[0216] In some embodiments, the second information can be the capability information of the terminal.

[0217] It should be noted that the terminal can send the second information to the network device to indicate the capability of the terminal; if the second information indicates that the terminal does not support sending the second type of DSR, the network device can configure the terminal to use the first type of DSR for DSR reporting; if the second information indicates that the terminal supports sending the second type of DSR, the network device can configure the terminal to use the second type of DSR for DSR reporting.

[0218] If the second information indicates that the terminal does not support sending the first DSR, the network device can configure the terminal to use the first type of DSR and / or the second type of DSR for DSR reporting. It can be understood that in the case that the terminal does not support sending the first DSR, if the resource length of the first resource is less than the resource length required for sending the second type of DSR, the terminal can send the first information to the network device to request the second resource; or the terminal can send the first type of DSR to the network device.

[0219] If the second information indicates that the terminal supports sending the first DSR, the network device can configure the terminal to use the second type of DSR and / or the first DSR for DSR reporting. It can be understood that in the case that the terminal supports sending the first DSR, if the resource length of the first resource is less than the resource length required for sending the second type of DSR, the terminal sends the first DSR according to the sorting result.

[0220] In some embodiments, the method further comprises one of the following: determining the maximum number of information fields that one LCG in the second type of DSR can carry according to a protocol; and determining the maximum number of information fields that one LCG in the second type of DSR can carry according to third information sent by the network device.

[0256] In some embodiments, the first resource is an uplink grant resource.

[0257] In some embodiments, the above method can include the methods of the above communication system side, terminal side, network device side, and the like, which will not be described here.

[0258] In order to better understand the embodiments of the present disclosure, the present disclosure will be further described below through some example embodiments.

[0259] In some embodiments, a second type of DSR triggering reporting scheme is introduced.

[0260] a) The second type of DSR will carry at least one set of reporting fields (i.e. remaining time and buffer size fields) for one LCG.

[0261] Here, the reporting domain can be understood as the information domain in the present disclosure.

[0262] In some embodiments, the second type of DSR reporting is triggered in mode 1, and the specific process includes, after logical channel multiplexing, if the current first resource can carry the second type of DSR MAC CE, sending the second type of DSR MAC CE; if the current first resource is not enough to carry the second type of DSR MAC CE, sending an SR to the network to reapply for the first resource.

[0263] Among them, the second type of DSR MAC CE that can be carried means that the first resource can accommodate the DSR MAC CE and its subheader.

[0264] In some embodiments, the second type of DSR reporting is triggered in mode 2, and the specific process includes, after logical channel multiplexing, if the current first resource can carry the second type of DSR MAC CE, sending the second type of DSR MAC CE; if the current first resource is not enough to carry the second type of DSR MAC CE, determining whether the current first resource can carry the first type of DSR MAC CE.

[0265] Among them, the second type of DSR MAC CE that can be carried means that the first resource can accommodate the DSR MAC CE and its subheader.

[0266] In the case of determining whether the current first resource can carry the first type of DSR MAC CE, if the current first resource can carry the first type of DSR MAC CE, the first type of DSR MAC CE is sent; if the current first resource is not enough to carry the first type of DSR MAC CE, an SR is sent to the network to apply for the first resource.

[0267] Mode 2 can fall back to sending in the first DSR MAC CE format when the grant is not enough to carry the second type of DSR MAC CE compared to mode 1.

[0268] In some embodiments, the second type of DSR reporting is triggered in mode 3, and the specific process includes, after logical channel multiplexing, if the current first resource can carry the second type of DSR MAC CE, sending the second type of DSR MAC CE; if the current first resource is not enough to carry the second type of DSR MAC CE, a truncation or puncturing operation can be performed to meet the size limit of the first resource.

[0269] a) Truncation or puncturing operation, that is, the DSR reporting of LCG is performed in descending order of logical channel group (that is, the emergency data of the LCG with high priority is preferentially reported).

[0270] b) The priority level of a LCG is determined by the highest priority logical channel associated with it. The logical channel can be one that has emergency scheduling data requirement only, or one that contains both logical channels with emergency scheduling requirement and logical channels without emergency scheduling requirement.

[0271] c) If the priority level of logical channel groups is the same, the LCGs are ordered by LCG ID for prioritized transmission.

[0272] d) The transmission of emergency data of LCGs that are ordered later can be one of the following:

[0273] First way: The emergency data of the LCG is not reported in the second type of DSR MAC CE.

[0274] Second way: The emergency data of the LCG is reported in the second type of DSR MAC CE, but falls back to the format of the first type of DSR MAC CE. That is, only one set of reporting fields is reported.

[0275] Third way: The emergency data of the LCG is reported in the second type of DSR MAC CE, but cannot report all reporting fields, only part of the reporting fields, until the first resource is used up.

[0276] For example, assuming that LCG1 and LCG2 are ordered, LCG1 is ordered first and LCG2 is ordered later. At this time, the emergency data of LCG1 is placed first, and its format can be the second type of DSR MAC CE format, but the remaining grant is not enough to carry the emergency data of LCG2 in the second type of DSR MAC CE format, then the emergency data of LCG2 can be in the first type of DSR MAC CE format; or the emergency data of LCG2 is not reported; or part of the reporting fields is reported until the resource is used up.

[0277] e) The transmission of emergency data of LCGs that are ordered first or the reporting fields in the second type of DSR format can be N sets of reporting fields, where N can be a protocol agreement or network configuration. For example, the network configures 3 segment areas, then the buffer size of 3 segment areas is reported.

[0278] For example, assume that LCG1 and LCG2 are sorted, and LCG1 is sorted in front of LCG2. At this time, the emergency data of LCG1 is placed first, and the format can be the second type of DSR MAC CE format (assuming 3 reporting fields). However, the remaining authorization is insufficient to carry the emergency data of LCG2 in the second type of DSR MAC CE format (insufficient to place 3 reporting fields). At this time, in order to report the emergency data of the two LCGs, the second type of DSR MAC CE format can not place all reporting fields (such as 3 reporting fields) when reporting the emergency data of LCG1 and LCG2, but can place fewer reporting fields, such as N reporting fields (such as 2 reporting fields), to reserve space for LCG2.
