[0044] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0045] 1. Data volume statistics during the Buffer Status Reporting (BSR) process

[0046] When a user equipment (UE) exchanges data with the network, to assist the network with uplink scheduling, the UE needs to inform the network of the amount of uplink data pending transmission in its buffer (buffer status). After obtaining this information, the network can allocate uplink resources of appropriate size to the UE. The process of reporting buffer status is called buffer status reporting (BSR).

[0047] At a point in time, a UE may have uplink data for multiple services to be transmitted. These data have different Quality of Service (QoS) requirements. In order to allow the network to implement different scheduling strategies for data with different QoS requirements, the UE can map the uplink data to different logical channels according to the network configuration. Different logical channels correspond to the same or different scheduling priorities. The network can configure one or more logical channels with similar QoS requirements into a logical channel group. The UE supports up to 16 logical channels (LCH) and 8 logical channel groups (LCG).

[0048] The UE reports the BSR at the granularity of the logical channel group. That is, the amount of uplink data to be transmitted on all logical channels in each logical channel group (LCG) is added together, and the result is mapped to a BS index according to the mapping table defined by the protocol (the mapping table indicates the correspondence between the buffer status (BS) value and the index). During the BSR process, the UE reports the index value corresponding to the BS value of each LCG. The BS index value has two formats, with a length of 5 bits or 8 bits. The purpose of the UE reporting the BSR according to the logical channel group (rather than the logical channel) is to reduce the overhead of BSR reporting.

[0049] The BSR is generated and reported by the Medium Access Control (MAC) layer. According to the protocol in the relevant technology, when the MAC layer triggers the BSR report or the BSR MAC Control Element (CE) generates it, the UE's MAC entity needs to calculate the uplink buffer status based on the uplink data to be sent in one or more logical channels of the Radio Link Control (RLC) and Packet Data Convergence Protocol (PDCP) layers.

[0050] 2. RLC data volume evaluation:

[0051] For the purpose of MAC buffer status reporting, the UE shall consider the following as RLC data volume:

[0052] RLC Service Data Unit (SDU) and RLC SDUs and RLC SDU segments that have not yet been included in an RLC data PDU;

[0053] RLC data PDUs that are pending for initial transmission;

[0054] RLC data PDUs that are pending for retransmission (RLC AM)

[0055] In addition, if a STATUS PDU has been triggered and t-StatusProhibit is not running or has expired, the UE shall estimate the size of the STATUS PDU that will be transmitted in the next transmission opportunity, and consider this as part of RLC data volume.

[0056] 3. PDCP data volume assessment:

[0057] For the purpose of MAC buffer status reporting, the transmitting PDCP entity shall consider the following as PDCP data volume:

[0058] the PDCP SDUs for which no PDCP Data PDUs have been constructed;

[0059] The PDCP Data PDUs that have not been submitted to lower layers;

[0060] the PDCP Control PDUs;

[0061] PDCP SDUs to be retransmitted for AM DRBs

[0062] For AM DRBs, the PDCP Data PDUs to be retransmitted.

[0063] The following, in conjunction with the accompanying drawings, describes in detail the information reporting method, apparatus, terminal, and network-side equipment provided in the embodiments of the present application through some embodiments and their application scenarios.

[0064] Referring to FIG. 2 , FIG. 2 is a flow chart of an information reporting method provided in an embodiment of the present application. As shown in FIG. 2 , the information reporting method includes the following steps:

[0065] Step 101: The terminal determines target statistical data based on the remaining duration of a discard timer corresponding to data to be transmitted, where the data to be transmitted is data to be transmitted by the terminal to a network-side device.

[0066] The data to be transmitted may be uplink data to be transmitted. The data to be transmitted may include: PDCP SDU; PDCP PDU (or RLC SDU); RLC PDU; RLC SDU segment; etc. This embodiment does not limit the type of data to be transmitted. RLC PDU can also be described as RLC data PDU, and PDCP PDU can also be described as PDCP data PDU.

[0067] Among them, the discard timer corresponding to the data to be transmitted may be a discard timer (discardTimer) that is started when the PDCP SDU corresponding to the data to be transmitted reaches the PDCP layer. Taking the data to be transmitted as a PDCP SDU as an example, the discard timer corresponding to the data to be transmitted may be a discardTimer that is started when the PDCP SDU reaches the PDCP layer; Taking the data to be transmitted as a PDCP PDU as an example, the discard timer corresponding to the data to be transmitted may be a discardTimer that is started when the PDCP SDU corresponding to the PDCP PDU reaches the PDCP layer, and the PDCP SDU corresponding to the PDCP PDU is the PDCP SDU used to generate the PDCP PDU; Taking the data to be transmitted as an RLC PDU as an example, the discard timer corresponding to the data to be transmitted may be a discardTimer that is started when the PDCP SDU corresponding to the RLC PDU reaches the PDCP layer, and the PDCP SDU corresponding to the RLC PDU is the PDCP SDU used to generate the RLC PDU.

[0068] It should be noted that when a data packet (PDCP SDU) arrives at the PDCP layer, a discardTimer associated with the PDCP SDU will be started, and the running time of the discardTimer is pre-configured.

[0069] Among them, the remaining duration of the discard timer (discardTimer) can be the duration until the discard timer times out. The maximum running duration of the discard timer is pre-configured, and when the running duration of the discard timer reaches the maximum running duration, the discard timer times out. The remaining duration of the discard timer can be the difference between the maximum running duration of the discard timer and the current running duration of the discard timer; or, the remaining duration of the discard timer can also be the difference between the maximum running duration of the discard timer and the running duration of the discard timer at the target deadline. The target moment can be a moment that can be determined by both the terminal and the network side according to preset rules, for example: the generation moment of the reporting signaling carrying the remaining duration information, or the moment of sending at the air interface, or the moment of the first sending at the air interface. In different application scenarios, the terminal can use different calculation methods to calculate the remaining duration.

[0070] In one embodiment, the target statistical data includes data in which the remaining duration of the discard timer in the data to be transmitted is less than or equal to the preset duration; or, the target statistical data includes data in which the remaining duration of the discard timer in the data to be transmitted is less than or equal to the preset duration, and the target statistical data also includes data packets located in the cache of the RLC layer of the terminal and whose corresponding discard timer has timed out.

[0071] Step 102: The terminal sends first indication information to the network side device, where the first indication information is used to indicate the data volume of the target statistical data.

[0072] Among them, the first indication information may include: the data volume of the target statistical data; or, the first indication information may include: the interval where the data volume of the target statistical data is located; or, the first indication information may include: the index value corresponding to the data volume of the target statistical data; or, the first indication information may include: the index value corresponding to the interval where the data volume of the target statistical data is located; etc. This embodiment does not limit the first indication information.

[0073] In one embodiment, the target statistical data volume may be a buffer status (BS) value. The terminal may report the target statistical data volume according to a protocol-defined mapping table (the mapping table indicates the correspondence between BS values ​​and indexes). The first indication information may be a BS index value. During the BSR process, the terminal reports the index value corresponding to the BS value. The BS index value has two formats, with a length of 5 bits or 8 bits.

[0074] Table 1 gives an example of the mapping relationship between the BS index value and the BS value (ie, the data volume of the target statistical data): According to this example, when the BS value is 50 bytes, the corresponding BS index value (ie, the first indication information) is 6.

[0075] Table 1

[0076] In addition, the terminal can report the data volume of the target statistical data with the granularity of the logical channel group, the logical channel, or the DRB. Taking the data volume of the target statistical data with the granularity of the logical channel group as an example, the data volume of the target statistical data in the uplink to-be-transmitted data of all logical channels in each logical channel group (LCG) is added together, and the result is obtained according to the mapping table defined by the protocol to obtain the first indication information for reporting. For example, during the BSR process, the terminal reports the index value corresponding to the BS value (that is, the data volume of the target statistical data) of each LCG.

[0077] In one implementation, the terminal may send first indication information to the network-side device during a BSR process, where the first indication information is used to indicate a data volume of the target statistical data.

[0078] In one embodiment, the method further includes: the terminal sending third indication information to the network-side device, the third indication information being used to indicate at least one of the following: a minimum remaining duration of a discard timer corresponding to the first statistical data; and a maximum running duration of the discard timer corresponding to the first statistical data. The first statistical data includes data in the target statistical data where the remaining duration of the discard timer is less than or equal to a preset duration.

[0079] In one embodiment, the terminal determines the target statistical data based on the remaining duration of the discard timer corresponding to the data to be transmitted, where the data to be transmitted is the data to be transmitted by the terminal to the network side device; the terminal determines the data volume of the target statistical data; the terminal sends a first indication information to the network side device, and the first indication information is used to indicate the data volume of the target statistical data.

[0080] It should be noted that, on the terminal side, after the uplink data packet reaches the PDCP layer, PDCP will start a timer (i.e., a discard timer). When the timer expires: if the data packet has not been delivered to the lower layer (RLC layer), the PDCP layer will discard the data packet; if the data packet has been delivered to the lower layer (RLC layer), the PDCP layer will send a discard indication to the RLC layer (If the corresponding PDCP Data PDU has already been submitted to lower layers, the discard is indicated to lower layers). In an embodiment of the present application, when a data packet is about to time out (for example, the remaining duration of the timer is less than or equal to a specific threshold value), the terminal can report the amount of data that is about to time out, so that the network can speed up scheduling and reduce the probability of the data packet being discarded due to timeout.

[0081] It should be noted that if the discardTimer expires, uplink data packets may be discarded before being transmitted over the air interface, affecting the user experience. If important service data is discarded, the user experience may be poor. In this embodiment of the present application, the terminal can report the amount of data that is about to time out so that the network side can schedule it as soon as possible, thereby improving the user experience.

[0082] In an embodiment of the present application, the terminal determines target statistical data based on the remaining duration of the discard timer corresponding to the data to be transmitted, where the data to be transmitted is the data to be transmitted by the terminal to the network-side device; the terminal sends a first indication message to the network-side device, where the first indication message is used to indicate the data volume of the target statistical data. In this way, the terminal sends the data volume of the target statistical data determined based on the remaining duration of the discard timer corresponding to the data to be transmitted to the network-side device, thereby supporting the network-side device to consider the data volume of the target statistical data with a smaller remaining duration of the discard timer to allocate uplink transmission resources to the terminal, which can reduce the probability of the data to be transmitted on the terminal side being discarded / suspended due to timeout, thereby reducing the probability of terminal service failure. In addition, reducing the probability of the data to be transmitted on the terminal side being discarded / suspended due to timeout can also improve user experience.

[0083] Optionally, the target statistical data includes data in which the remaining duration of a discard timer in the data to be transmitted is less than or equal to a preset duration.

[0084] The preset duration may be configured by the network side device or agreed upon by a protocol. Data whose remaining duration of the discard timer is less than or equal to the preset duration may be considered as data that is about to time out.

[0085] In one embodiment, for a certain logical channel or DRB or logical channel group, the network side or protocol can configure a time threshold Tthreshold (i.e., a preset duration); the PDCP layer of the UE determines a set of data packets to be included in the statistics, and the remaining time of the discardTimer of the data in the set of data packets to be included in the statistics is less than or equal to Tthreshold. The PDCP layer counts the data volume of the data packets in the data packet set that have not yet been sent to the RLC; the PDCP layer notifies the RLC layer of the information of the data packets in the data packet set that have been sent to the RLC layer, such as the identifier, and the RLC counts the data volume corresponding to the data packets in the data packet set that have been sent to the RLC layer. The terminal (such as the UE MAC layer entity) uses the sum of the data volume counted by the PDCP layer and the data volume counted by the RLC layer as the data volume of the target statistical data.

[0086] In this embodiment, the target statistical data includes data in which the remaining duration of the discard timer in the data to be transmitted is less than or equal to the preset duration, so that the terminal reports to the network side device the amount of data in which the remaining duration of the discard timer in the data to be transmitted is less than or equal to the preset duration. The network side device can allocate uplink transmission resources that are adapted to the reported data amount to the terminal based on the reported data amount, and can reduce the probability of the data to be transmitted on the terminal side being discarded / transmission terminated due to timeout.

[0087] Optionally, the target statistical data includes at least one of first statistical data and second statistical data, and the terminal determines the target statistical data based on the remaining duration of a discard timer corresponding to the data to be transmitted, including at least one of the following:

[0088] The Packet Data Convergence Protocol (PDCP) layer of the terminal determines a first data packet in the PDCP layer based on a remaining duration of a discard timer corresponding to data to be transmitted, where the first statistical data includes the first data packet;

[0089] The PDCP layer of the terminal determines a second data packet to be transmitted to the radio link control RLC layer of the terminal based on the remaining duration of the discard timer corresponding to the data to be transmitted, and the second statistical data is determined based on the second data packet.

[0090] The first data packet may include a data packet for which the remaining duration of a discard timer in the PDCP layer is less than or equal to a preset duration. The first data packet may be data to be transmitted by the terminal to a network-side device. For example, the first data packet may be a PDCP SDU for which the remaining duration of a discard timer is less than or equal to a preset duration.

[0091] The second data packet may include a data packet transmitted to the RLC layer of the terminal and the corresponding discard timer has a remaining duration less than or equal to a preset duration; or the second data packet may include a data packet transmitted to the RLC layer of the terminal and the corresponding discard timer has a remaining duration less than or equal to a preset duration, and the second data packet may also include a data packet located in the cache of the RLC layer of the terminal and the corresponding discard timer has timed out. The second data packet may be data to be transmitted by the terminal to the network-side device. For example, the second data packet may be a PDCP PDU with a remaining discard timer less than or equal to a preset duration.

[0092] It should be noted that the data received by the PDCP layer is called a PDCP SDU; the data sent by the PDCP layer to the next layer (ie, the RLC layer) is called a PDCP PDU, and the PDCP PDU is the RLC SDU.

[0093] In addition, the RLC layer of the terminal may determine the second statistical data based on the second data packet.

[0094] In this embodiment, the PDCP layer of the terminal determines the first data packet in the PDCP layer based on the remaining duration of the discard timer corresponding to the data to be transmitted, and the first statistical data includes the first data packet. In this way, the PDCP layer can count the first data packet whose remaining duration of the discard timer in the PDCP layer is less than or equal to the preset duration, and include the data volume of the first data packet in the data volume of the target statistical data reported to the network side, thereby supporting the network side device to consider the first data packet in the PDCP layer that is about to time out to allocate uplink transmission resources to the terminal, which can reduce the probability of data packet timeout in the PDCP layer of the terminal, and further reduce the probability of data packet in the PDCP layer being discarded / termination of transmission due to timeout.

[0095] In this embodiment, the PDCP layer of the terminal determines the second data packet transmitted to the radio link control RLC layer of the terminal based on the remaining duration of the discard timer corresponding to the data to be transmitted, and the second statistical data is determined based on the second data packet. In this way, the PDCP layer can count the second data packet transmitted to the RLC layer of the terminal and the remaining duration of the discard timer is less than or equal to the preset duration, so that the RLC layer includes the data volume of the second data packet in the data volume of the target statistical data reported to the network side, thereby supporting the network side device to consider the second data packet transmitted to the RLC layer of the terminal that is about to time out to allocate uplink transmission resources to the terminal, which can reduce the probability of the data packet transmitted to the RLC layer of the terminal timing out, and further reduce the probability of the data packet transmitted to the RLC layer of the terminal being discarded / termination of transmission due to timeout.

[0096] Optionally, the first data packet includes a data packet whose remaining duration of a discard timer in the PDCP layer is less than or equal to a preset duration;

[0097] or,

[0098] The second data packet includes a data packet transmitted to the RLC layer of the terminal and the remaining duration of the corresponding discard timer is less than or equal to the preset duration.

[0099] Optionally, after the PDCP layer of the terminal determines, based on the remaining duration of the discard timer corresponding to the data to be transmitted, a second data packet to be transmitted to the RLC layer of the terminal, the method further includes:

[0100] The RLC layer of the terminal determines the second statistical data based on the second data packet.

[0101] The second statistical data may include: the second data packet or segmented data of the second data packet that does not generate an RLC data PDU; the first RLC data PDU generated by the second data packet that has not started transmission; the second RLC data PDU generated by the second data packet that is waiting for retransmission; and so on.

[0102] In this embodiment, the PDCP layer of the terminal determines the second data packet to be transmitted to the RLC layer of the terminal based on the remaining duration of the discard timer corresponding to the data to be transmitted, and the RLC layer of the terminal determines the second statistical data based on the second data packet, so that the RLC layer can realize the statistics of the amount of data to be reported by the RLC layer through the second data packet counted by the PDCP layer.

[0103] Optionally, before the RLC layer of the terminal determines the second statistical data based on the second data packet, the method further includes:

[0104] The RLC layer of the terminal receives second indication information sent by the PDCP layer of the terminal, where the second indication information is used to indicate the second data packet.

[0105] The second indication information may include relevant information of the second data packet, such as an identifier; or the second indication information may include a first identifier, the first identifier being the identifier of the data packet with the largest identifier in the second data packet or the first identifier being the identifier of the second data packet in the second data packet that is last or latest sent by the PDCP layer to the RLC layer; or the second indication information may include a second identifier, the difference between the second identifier and the identifier of the data packet with the largest identifier in the second data packet is 1 or the difference between the second identifier and the identifier of the second data packet in the second data packet that is last or latest sent by the PDCP layer to the RLC layer is 1; or the second indication information may include a third identifier, the third identifier being greater than the identifier of the data packet with the largest identifier in the second data packet or the third identifier being greater than the identifier of the second data packet in the second data packet that is last or latest sent by the PDCP layer to the RLC layer, the difference between the third identifier and the identifier of the data packet with the largest identifier in the second data packet may be configured by a network side device or agreed upon by a protocol, or the difference between the third identifier and the identifier of the second data packet that is last or latest sent by the PDCP to the RLC layer may be configured by a network side device or agreed upon by a protocol; and so on. This embodiment does not limit the second indication information. The above identifiers (such as the first identifier or the second identifier or the third identifier or the identifier of the second data packet) are all identifiers allocated to the same PDCP entity.

[0106] In one embodiment, the PDCP layer of the terminal notifies the RLC layer of the identifiers (such as numbers) of all PDCP SDUs that are about to time out, so that the RLC layer can perform data volume statistics on the timed-out data. The PDCP layer can notify the RLC layer of the PDCP layer number (such as PDCP SN or counter) of the timed-out PDCP SDU, and the RLC layer performs data volume statistics on the PDCP layer number notified by the PDCP layer; or, the PDCP layer can notify the RLC layer of the last PDCP layer number of all timed-out PDCP SDUs, and the RLC layer performs data volume statistics on the PDCP layer number notified by the PDCP layer and the data of the PDCP SDUs before the PDCP layer number.

[0107] In this embodiment, the RLC layer of the terminal receives the second indication information sent by the PDCP layer of the terminal, and the second indication information is used to indicate the second data packet. The RLC layer of the terminal determines the second statistical data based on the second data packet. In this way, the RLC layer can know the data packet to be counted exactly through the second indication information sent by the PDCP layer, thereby realizing the statistics of the amount of data to be reported by the RLC layer.

[0108] Optionally, the second indication information includes at least one of the following:

[0109] an identifier of the second data packet;

[0110] a first identifier, where the first identifier is the identifier of the data packet with the largest identifier among the second data packets, or the first identifier is the identifier of the data packet in the second data packets that is sent latest from the PDCP layer to the RLC layer;

[0111] The second identifier, the difference between the second identifier and the identifier of the data packet with the largest identifier in the second data packet is 1, or the difference between the second identifier and the identifier of the data packet in the second data packet that is sent latest from the PDCP layer to the RLC layer is 1.

[0112] Among them, the first identifier is the identifier of the data packet in the second data packet that is sent from the PDCP layer to the RLC layer last. It can be understood that the first identifier is the identifier of the data packet in the second data packet that is sent from the PDCP layer to the RLC layer last.

[0113] Among them, the difference between the second identifier and the identifier of the data packet in the second data packet that is last sent by the PDCP layer to the RLC layer is 1. It can be understood that the difference between the second identifier and the identifier of the data packet in the second data packet that is last sent by the PDCP layer to the RLC layer is 1.

[0114] The second indication information may include an identifier of the second data packet, and the identifier of the second data packet may be a number of the second data packet at the PDCP layer, such as a PDCP serial number. number, SN) or PDCP count value (counter); or, the second indication information may include a first identifier, the first identifier is the identifier of the data packet with the largest identifier in the second data packet, the RLC layer determines the data packet with the largest identifier in the second data packet through the first identifier, and takes the data packet with an identifier less than or equal to the first identifier as the second data packet; or, the second indication information may include a first identifier, the first identifier is the identifier of the data packet in the second data packet that is sent by the PDCP layer to the RLC layer latest, the RLC layer takes the data packet with the first identifier and the data packet received before the data packet with the first identifier as the second data packet; or, the second indication information may include a second identifier, the difference between the second identifier and the identifier of the data packet with the largest identifier in the second data packet is 1, the RLC layer determines the data packet with the largest identifier in the second data packet through the difference between the second identifier and 1, and takes the data packet with an identifier less than the second identifier as the second data packet; or, the second indication information may include a second identifier, the difference between the second identifier and the identifier of the data packet in the second data packet that is sent by the PDCP layer to the RLC layer latest is 1, the RLC layer takes the data packet received before the data packet with the second identifier as the second data packet.

[0115] In this implementation, the RLC layer can quickly determine the data packet that is about to time out through the identifier of the second data packet, the first identifier, or the second identifier.

[0116] Optionally, the second statistical data includes at least one of the following:

[0117] the second data packet for which no RLC data PDU is generated;

[0118] Segmented data of the second data packet for which no RLC data PDU is generated;

[0119] a first RLC data PDU generated by the second data packet, wherein the first RLC data PDU has not started initial transmission;

[0120] The second data packet generates a second RLC data PDU, and the second RLC data PDU waits for retransmission by the RLC layer.

[0121] The second data packet for which no RLC data PDU is generated may be an RLC SDU;

[0122] The segmented data of the second data packet from which the RLC data PDU is not generated may be RLC SDUs and RLC SDU segments that have not yet been included in an RLC data PDU;

[0123] The first RLC data PDU may be an RLC data PDU that is pending for initial transmission;

[0124] The second RLC data PDU may be RLC data PDUs that are pending for retransmission (RLC AM).

[0125] It should be noted that the second data packet transmitted from the PDCP layer to the RLC layer is a PDCP PDU or RLC SDU. The RLC layer processes the second data packet to generate an RLC PDU. The data obtained after the RLC layer processes the second data packet is an RLC SDU segment and / or an RLC PDU.

[0126] It should be noted that, depending on the size of the air interface resources allocated by the network side, sometimes the RLC PDU generated by the complete RLC SDU can be mapped to an air interface time-frequency resource; sometimes the RLC PDU generated by the complete RLC SDU cannot be mapped to an air interface time-frequency resource (in this case, the allocated air interface resources are smaller than the size required for the transmission of the RLC PDU generated by the complete RLC SDU). In this case, the RLC SDU needs to be segmented, with the first segment generating an RLC PDU; the second segment serves as an RLC SDU segment waiting to be mapped to the subsequently scheduled resources on the network side for transmission. An RLC PDU can carry the data of an RLC SDU and the corresponding RLC header; or the data of an RLC SDU segment and the corresponding RLC header.

[0127] Optionally, the target statistical data further includes: data packets that are located in the cache of the RLC layer of the terminal and whose corresponding discard timers have timed out.

[0128] The PDCP layer of the terminal indicates to the RLC layer that the data packet whose timer has timed out is discarded. In one embodiment, for a data packet that has been sent to the RLC, when the discard timer associated with the data packet times out, the PDCP layer of the terminal indicates to the RLC layer that it is discarded.

[0129] In addition, the second statistical data may include the data packets located in the buffer of the RLC layer of the terminal and whose corresponding discard timers have timed out. When determining the second statistical data, the RLC layer of the terminal may include the data packets located in the buffer of the RLC layer of the terminal and whose corresponding discard timers have timed out in the second statistical data. The RLC layer of the terminal may include the data packets located in the buffer of the RLC layer and whose corresponding discard timers have timed out as indicated by the PDCP layer to the RLC layer in the second statistical data.

[0130] Among them, the data packet that the PDCP layer indicates to the RLC layer that the corresponding discard timer has timed out may be that the PDCP layer indicates to the RLC layer that the corresponding discard timer of certain data packets has timed out, or that the PDCP layer instructs the RLC layer to discard certain data packets, and the data packet indicated to be discarded is a data packet whose corresponding discard timer has timed out.

[0131] In addition, when performing data volume statistics, the RLC layer may also add data of the PDCP SDU that is instructed to be discarded by the PDCP layer into the data volume statistics.

[0132] In one embodiment, if a data packet or a segment of a data packet whose discardTimer times out (i.e., is indicated to be discarded by the PDCP layer) is waiting for initial transmission or retransmission in the RLC layer, or an RLC SDU containing the data packet or a segment of the data packet is waiting for initial transmission or retransmission in the RLC layer, then the RLC can also count the amount of data of the data packet whose discardTimer times out or is indicated to be discarded by the PDCP layer. In some cases, after the data is transmitted from PDCP to RLC, even if the discardTimer times out or is indicated to be discarded by the PDCP layer, the RLC is not allowed to discard it. In this case, the data packet that times out or is indicated to be discarded by the PDCP layer also needs to be included in the statistics. Because the data packet that times out or is indicated to be discarded by the PDCP layer will be sent to the network side before the data packet that is about to time out, in order to avoid data packet timeout, the network side needs to allocate resources large enough to the UE to accommodate the data packets that have timed out / are indicated to be discarded by the PDCP layer and are about to time out.

[0133] It should be noted that when the discardTimer expires for a PDCP SDU, the PDCP layer shall discard the PDCP SDU along with the corresponding PDCP Data PDU. If the corresponding PDCP Data PDU has already been submitted to the RLC layer, the discard is indicated to the RLC layer.

[0134] In this embodiment, the target statistical data also includes: data packets located in the cache of the RLC layer of the terminal and whose corresponding discard timers have timed out (i.e., data packets indicated by the PDCP layer to be discarded or the discard timer corresponding to the data packets indicated by the PDCP layer to have timed out), so that the data volume of data packets in the cache of the RLC layer whose discard timer has timed out or which are indicated by the PDCP layer to be discarded but not discarded can be included in the data volume of the target statistical data reported to the network side. The network side device can consider the data volume of data packets in the cache of the RLC layer whose discard timer has timed out or which are indicated by the PDCP layer to be discarded but not discarded to allocate adaptive uplink transmission resources to the terminal, so that the allocated uplink transmission resources can accommodate data packets that have timed out or are indicated by the PDCP layer to be discarded and are about to time out, thereby reducing the probability of timeout of data to be transmitted that has not timed out on the terminal side.

[0135] Optionally, the method further includes:

[0136] The terminal sends third indication information to the network-side device, where the third indication information is used to indicate at least one of the following:

[0137] the minimum value of the remaining duration of the discard timer corresponding to the target statistical data;

[0138] The maximum running time of the discard timer corresponding to the target statistical data.

[0139] In one embodiment, the target statistical data includes data in which the remaining duration of the discard timer in the data to be transmitted is less than or equal to a preset duration, and the terminal sends a third indication information to the network side device, and the third indication information is used to indicate at least one of the following: the minimum value of the remaining duration of the discard timer corresponding to the target statistical data; the maximum value of the running duration of the discard timer corresponding to the target statistical data.

[0140] In one embodiment, the report reported by the terminal may include both first indication information and third indication information. The first indication information is used to indicate the data volume of the data packets whose discardTimer has timed out and the data volume that will time out. The sum of the data volume that has timed out and the data volume that will time out is the urgent data volume. The third indication information is used to indicate the shortest remaining time in the discardTimer associated with the data packets whose discardTimer has not yet timed out.

[0141] In this embodiment, the terminal sends third indication information to the network-side device, and the third indication information is used to indicate at least one of the following: the minimum remaining duration of the discard timer corresponding to the target statistical data; the maximum running duration of the discard timer corresponding to the target statistical data. In this way, the network-side device can consider the minimum remaining duration of the discard timer or the maximum running duration of the discard timer to determine the time to schedule uplink transmission resources for the terminal, thereby minimizing the probability of the discard timer corresponding to some data to be transmitted timing out due to untimely scheduling, further reducing the probability of timeout of data to be transmitted that has not timed out on the terminal side, and reducing the possibility of discarded data to be transmitted.

[0142] Optionally, the preset duration is configured by the network side device or agreed upon by protocol.

[0143] Optionally, the method further includes:

[0144] The terminal sends fourth indication information to the network side device, where the fourth indication information is used to indicate the sum of the data volumes of data packets whose corresponding discard timers have timed out in the data to be transmitted.

[0145] In one embodiment, the first indication information is used to indicate the data volume of the target statistical data, and the target statistical data may include data in the data to be transmitted whose remaining duration of the discard timer is less than or equal to the preset duration, and the target statistical data may be data in the data to be transmitted whose corresponding discard timer has not timed out. The fourth indication information may be used to indicate the sum of the data volumes of data packets located in the RLC layer cache of the terminal and whose corresponding discard timers have timed out.

[0146] It should be noted that the terminal can carry the first indication information and the fourth indication information in the same report, and use the first indication information to indicate the amount of data that will time out, and use the fourth indication information to indicate the amount of data that has timed out, so as to facilitate scheduling on the network side.

[0147] Referring to FIG3 , FIG3 is a flow chart of an information reporting method provided in an embodiment of the present application. As shown in FIG3 , the information reporting method includes the following steps:

[0148] Step 201: A network-side device receives first indication information sent by a terminal, where the first indication information is used to indicate the data volume of target statistical data.

[0149] The target statistical data is determined based on the remaining duration of a discard timer corresponding to the data to be transmitted of the terminal, and the data to be transmitted is data to be transmitted by the terminal to the network side device.

[0150] Optionally, the target statistical data includes data in which the remaining duration of a discard timer in the data to be transmitted is less than or equal to a preset duration.

[0151] Optionally, after the network-side device receives the first indication information sent by the terminal, the method further includes:

[0152] The network-side device allocates uplink transmission resources to the terminal based on the first indication information.

[0153] Optionally, the target statistical data further includes: data packets that are located in the cache of the RLC layer of the terminal and whose corresponding discard timers have timed out.

[0154] Optionally, the preset duration is configured by the network side device or agreed upon by protocol.

[0155] Optionally, the method further includes:

[0156] The network-side device receives third indication information sent by the terminal, where the third indication information is used to indicate at least one of the following:

[0157] the minimum value of the remaining duration of the discard timer corresponding to the target statistical data;

[0158] The maximum running time of the discard timer corresponding to the target statistical data.

[0159] Optionally, the method further includes:

[0160] The network side device receives fourth indication information sent by the terminal, where the fourth indication information is used to indicate the sum of data volumes of data packets whose corresponding discard timers in the data to be transmitted have timed out.

[0161] In an embodiment of the present application, the terminal sends a target statistical data volume determined based on the remaining duration of the discard timer corresponding to the data to be transmitted to the network side device, thereby supporting the network side device to consider the target statistical data volume with a smaller remaining duration of the discard timer to allocate uplink transmission resources to the terminal, which can reduce the probability of the terminal side's to-be-transmitted data being discarded / transmission terminated due to timeout, thereby reducing the probability of terminal service failure.

[0162] It should be noted that this embodiment is an implementation of the network side device corresponding to the embodiment shown in Figure 2. Its specific implementation can refer to the relevant description of the embodiment shown in Figure 2. To avoid repetition, this embodiment will not be repeated.

[0163] The following describes the information reporting method provided by the embodiment of the present application through several specific examples:

[0164] Example 1:

[0165] Step (11): The UE receives configuration information of the network side device: the time threshold Tthreshold of DRB1 or PDCP entity 1.

[0166] Step (12), for uplink data transmitted via DRB1 or PDCP entity 1, when data packet 1, data packet 2, data packet 3 and data packet 4 arrive at the PDCP layer of the UE successively, the PDCP layer starts discardTimer1, discardTimer2, discardTimer3 and discardTimer4 respectively.

[0167] Step (13), when the UE generates the reporting information, the PDCP layer of the UE checks the remaining time of discardTimer1, discardTimer2, discardTimer3 and discardTimer4, wherein the remaining time of discardTimer1, discardTimer2 and discardTimer3 are all less than Tthreshold; the remaining time of discardTimer4 is greater than Tthreshold; data packet 1 and data packet 2 have been sent to the RLC layer, and data packet 3 has not yet been sent to the RLC layer.

[0168] Step (14), the PDCP layer of the UE counts the amount of data to be reported;

[0169] The PDCP layer of the UE counts the data packet size of data packet 3 into the amount of data to be reported.

[0170] Step (15), the PDCP layer notifies the UE's RLC layer that the data volume of data packet 1 and data packet 2 needs to be included in the data volume to be reported; for example, the PDCP layer can notify the RLC layer of a list of packet identifiers, which includes the packet identifiers of data packet 1 and data packet 2.

[0171] Step (16), the RLC layer of the UE counts the amount of data to be reported;

[0172] If data packet 1 or data packet 2 has not yet generated an RLC data PDU, the RLC layer counts the data volume of data packet 1 or data packet 2 that has not yet generated an RLC data PDU into the amount of data to be reported;

[0173] If the segmented data of data packet 1 or data packet 2 has not yet generated an RLC data PDU, the RLC layer will count the amount of the segmented data that has not yet generated an RLC data PDU into the amount of data to be reported;

[0174] If all or part of the data of Data Packet 1 or Data Packet 2 has generated an RLC data PDU, but initial transmission has not yet started, the RLC layer counts the generated RLC data PDU into the amount of data to be reported;

[0175] If all or part of the data of data packet 1 or data packet 2 has generated an RLC data PDU, but the RLC data PDU is waiting for retransmission, the RLC layer counts the RLC data PDU into the amount of data to be reported.

[0176] In step (17), the MAC layer of the terminal obtains the amount of data to be reported that will time out based on the amount of data to be reported counted by the PDCP layer and the amount of data to be reported counted by the RLC layer. The amount of data to be reported that will time out is the sum of the amount of data to be reported counted by the PDCP layer and the amount of data to be reported counted by the RLC layer.

[0177] The terminal reports the amount of data that will time out to be reported to the network side device, and the network side device schedules uplink resources based on the amount of data that will time out.

[0178] Example 2:

[0179] Steps (21) to (24): same as steps (11) to (14) of Example 1;

[0180] Step (25): The PDCP layer of the UE notifies the RLC layer of the UE that data packet 2 and the data packet previously sent to the RLC layer need to be counted in the amount of data to be reported; for example, the PDCP layer can notify the RLC layer of the identifier of data packet 2, and the data packet corresponding to the identifier in the RLC layer and the data packet before the data packet corresponding to the identifier need to be counted, that is, data packet 2 and data packet 1 need to be counted; or, the PDCP layer can notify the RLC layer of the identifier of data packet 3, and the data packets before the data packet corresponding to the identifier in the RLC layer need to be counted, that is, data packet 2 and data packet 1 need to be counted.

[0181] Step (26) to step (27): same as step (16) to step (17) of Example 1.

[0182] Example 3:

[0183] Step (31), the UE receives configuration information of the network side device: the time threshold Tthreshold of DRB1 or PDCP entity 1.

[0184] Step (32), for uplink data transmitted via DRB1 or PDCP entity 1, when data packet 1, data packet 2, data packet 3 and data packet 4 arrive at the PDCP layer of the UE successively, the PDCP layer starts discardTimer1, discardTimer2, discardTimer3 and discardTimer4 respectively.

[0185] Step (33): When discardTimer1 times out, the UE's PDCP layer notifies the UE's RLC layer that data packet 1 has timed out or the UE PDCP layer sends a discard indication of the associated data packet 1 to the RLC layer.

[0186] Step (34), when the UE generates the reporting information, the PDCP layer of the UE checks the remaining time of discardTimer1, discardTimer2, discardTimer3 and discardTimer4, wherein the remaining time of discardTimer2 and discardTimer3 is less than Tthreshold; the remaining time of discardTimer4 is greater than Tthreshold; data packet 1 and data packet 2 have been sent to the RLC layer, and data packet 3 has not yet been sent to the RLC layer.

[0187] Step (35), the PDCP layer of the UE counts the amount of data to be reported;

[0188] The PDCP layer of the UE counts the data packet size of data packet 3 into the amount of data to be reported.

[0189] Step (36), the RLC layer of the UE counts the amount of data to be reported;

[0190] If data packet 1 or data packet 2 has not yet generated an RLC data PDU, the RLC layer counts the data volume of data packet 1 or data packet 2 that has not yet generated an RLC data PDU into the amount of data to be reported;

[0191] If the segmented data of data packet 1 or data packet 2 has not yet generated an RLC data PDU, the RLC layer will count the amount of the segmented data that has not yet generated an RLC data PDU into the amount of data to be reported;

[0192] If all or part of the data of Data Packet 1 or Data Packet 2 has generated an RLC data PDU, but initial transmission has not yet started, the RLC layer counts the generated RLC data PDU into the amount of data to be reported;

[0193] If all or part of the data of data packet 1 or data packet 2 has generated an RLC data PDU, but the RLC data PDU is waiting for retransmission, the RLC layer counts the RLC data PDU into the amount of data to be reported.

[0194] It should be noted that although Data Packet 1 has timed out, the RLC layer may place Data Packet 1 in the buffer and will not lose it. The RLC layer will still transmit Data Packet 1 over the air interface. Therefore, Data Packet 1 placed in the RLC layer buffer needs to be included in the statistics.

[0195] In step (37), the MAC layer of the terminal obtains the amount of data to be reported that will time out based on the amount of data to be reported counted by the PDCP layer and the amount of data to be reported counted by the RLC layer. The amount of data to be reported that will time out is the sum of the amount of data to be reported counted by the PDCP layer and the amount of data to be reported counted by the RLC layer.

[0196] The terminal reports the amount of data that will time out to be reported to the network side device, and the network side device schedules uplink resources based on the amount of data that will time out.

[0197] For example, the UE can report the amount of timed-out data and the amount of timed-out data for the same LCH / LCG separately in the same reporting signaling, i.e., report two BS values, so that the network side can obtain more accurate and comprehensive information for scheduling uplink resources.

[0198] Example 4:

[0199] The shortest remaining value of the discard timer in the data packets reported by the UE that have not timed out, as reported by the BS; or the running time of the discard timer with the longest running time.

[0200] The reporting of the BS and the remaining time may be per LCH reporting or per LCG reporting.

[0201] In the embodiment of the present application, the terminal accurately determines the amount of reported data so that the network-side device allocates sufficient UL grant (uplink resources) to avoid uplink data timeout.

[0202] The information reporting method provided in the embodiment of the present application can be executed by an information reporting device. In the embodiment of the present application, the information reporting device performing the information reporting method is taken as an example to illustrate the information reporting device provided in the embodiment of the present application.
