Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication processing method and a communication device. Background Art

[0002] In the New Radio (NR) communication system, the terminal device usually performs uplink transmission based on the uplink resource allocation method of the Logical Channel Priority (LCP). The uplink resource allocation method based on LCP includes: the terminal device receives one or more uplink grants (UL Grant); the terminal device determines which logical channels are related to each uplink grant based on the attributes of each uplink grant and the configuration of each logical channel; for multiple logical channels related to the same uplink grant, the terminal device first allocates the transmission resources of the uplink grant to the logical channel of the corresponding priority (for example, the logical channel with the highest priority) based on the priority of each logical channel, at least considering the prioritized bit rate (PBR) of the logical channel. If there are remaining transmission resources for the uplink grant, the terminal device will allocate the remaining transmission resources to other logical channels related to the UL Grant according to the priority of each logical channel until the transmission resources of the UL Grant are allocated.

[0003] However, when the terminal device uses the above-mentioned uplink resource allocation method based on logical channel priority to allocate UL Grant transmission resources, it may result in the terminal device being unable to send the delay-sensitive data packet to be transmitted uplink to the network device within the preset time period after reaching Layer 2 (Layer 2) of the terminal device, and then the terminal device needs to discard the data packet, resulting in poor scheduling performance of the uplink transmission. Summary of the Invention

[0004] An embodiment of the present application provides a communication processing method and a communication device, which can send first data determined at least based on the remaining time of the data packet in the logical channel based on the trigger time or sending time of the delay status report, thereby facilitating improving the scheduling performance of uplink transmission.

[0005] In a first aspect, embodiments of the present application provide a communication processing method, which is executed by a terminal device, or by a device compatible with the terminal device, such as a processor, chip, or chip module. The method may include: based on a trigger time or a send time of a delay status report, sending first data using a first uplink granted transmission resource; wherein the first data is determined based on at least a remaining time of a data packet in a first logical channel, the first logical channel includes a logical channel configured with a discard timer or a remaining time threshold, and the first data includes data of at least one first logical channel.

[0006] Among them, the terminal device uses the first uplink authorization to send the first data based on the trigger time or sending time of the delay status report, which is determined at least based on the remaining time of the data packet in the logical channel. For example, the data in the data packet with insufficient remaining time in the first logical channel is sent first, which avoids the data packet in the logical channel from being discarded due to failure to send, thereby improving the scheduling performance of the uplink transmission.

[0007] In one possible implementation, sending the first data using the first uplink authorized transmission resources based on the triggering time or sending time of the delay status report includes: sending the first data using the first uplink authorized transmission resources after the sending time of the delay status report. In other words, sending the first data after the terminal device sends the delay status report reduces the processing complexity of the terminal device and improves the scheduling performance of the uplink transmission.

[0008] In one possible implementation, after the delay status report is sent, the first data is sent using the first uplink authorized transmission resource, including: after the delay status report is sent and the time interval between the delay status report and the delay status report is at least the first time duration, the first data is sent using the first uplink authorized transmission resource. That is, considering the uplink transmission delay of the delay status report and the scheduling delay of the network device according to the delay status report, after the terminal device sends the delay status report, the first data is sent after waiting for at least the first time duration, so that the network device can promptly schedule resources to the terminal device after obtaining the delay status report reported by the terminal device, that is, allocate reasonable transmission resources to the terminal device, so as to facilitate the terminal device to send data packets with insufficient remaining time, avoid the data packets in the logical channel from being discarded due to failure to send, and improve the scheduling performance of uplink transmission.

[0009] In one possible implementation, based on the triggering time or sending time of the delay status report, the first data is sent using the first uplink authorized transmission resource, including: before the triggering time of the delay status report, the first data is sent using the first uplink authorized transmission resource. That is, the terminal device sends the first data in advance before the triggering time of the delay status report, which is conducive to timely sending of data packets with insufficient remaining time, and the network device can parse the way in which the terminal device determines the first data based on the first data received from the terminal device, which is conducive to the network device reasonably allocating uplink resources to the terminal device, for example, allocating more uplink resources for logical channels that are sensitive to transmission delays, thereby helping the terminal device to reduce the triggering of delay status reports, which can effectively reduce the processing complexity of the terminal device and also help to reduce the overhead of air interface signaling.

[0010] In one possible implementation, sending the first data using the first uplink authorized transmission resource before the triggering time of the delay status report includes: sending the first data using the first uplink authorized transmission resource before the triggering time of the delay status report and when the time interval between the triggering time of the delay status report and the triggering time of the delay status report is at least a second duration. In other words, the terminal device sends the first data before the triggering time of the delay status report and at least the second duration in advance, so that the terminal device has sufficient time to send the first data, which helps to reduce the triggering or sending of the delay status report.

[0011] In a possible implementation, the second duration is configured by the network. For example, the terminal device receives configuration information of the second duration from the network device, thereby acquiring the second duration through the configuration information.

[0012] In one possible implementation, before the first data is sent using the transmission resources authorized by the first uplink, in response to the minimum remaining time of the data packet in the second logical channel being less than the remaining time threshold, a delay status report is triggered; the first logical channel includes the second logical channel; after the first data is sent using the transmission resources authorized by the first uplink, the above method further includes: in response to the remaining time of the data packet in the second logical channel being greater than or equal to the remaining time threshold, canceling the delay status report. That is, before the delay status report is triggered to prepare for sending, if the data packet in the second logical channel to which the data packet with the minimum remaining time for triggering the delay status report belongs is located, after being sent via the transmission resources authorized by the first uplink, the remaining time of the remaining data packet is greater than the remaining time threshold, that is, the remaining data packet has sufficient time to be sent, canceling the reporting of unnecessary delay status reports can reduce the processing overhead of the terminal device and the network device, and improve the scheduling performance of the uplink transmission.

[0013] In one possible implementation, after sending the first data using the transmission resources of the first uplink authorization based on the trigger time or the sending time of the delay status report, the above method further includes: in response to the remaining time of the data packet in the first logical channel being greater than or equal to the remaining time threshold, sending the second data using the second uplink authorization; wherein the second data is determined based on at least the priority of each logical channel. In other words, if the remaining time of the data packet in the first logical channel is greater than or equal to the remaining time threshold, that is, the data packets in the first logical channel have sufficient time to be sent, the second data to be sent is determined based on at least the priority of each logical channel, thereby achieving effective and accurate switching between a method of determining the data transmission based on at least the remaining time of the data packet in the first logical channel and a method of determining the data transmission based on at least the priority of each logical channel, thereby improving the scheduling performance of the uplink transmission.

[0014] In one possible implementation, before sending the first data using the transmission resources of the first uplink grant based on the triggering time or sending time of the delay status report, the method further includes: receiving downlink control signaling, the downlink control signaling being used to configure the first uplink grant; or receiving a configuration grant, the configuration grant being used to configure the first uplink grant. In other words, the first uplink grant can be dynamically scheduled via downlink control signaling or obtained via semi-static scheduling of the configuration grant.

[0015] In one possible implementation, the first data includes data in a third logical channel, the minimum remaining time of a data packet in the third logical channel is less than or equal to a remaining time threshold corresponding to the third logical channel, and the first logical channel includes the third logical channel. In other words, based on the triggering time or sending time of the delay status report, data in data packets whose minimum remaining time is less than or equal to the remaining time threshold is preferentially sent to avoid discarding these data packets, thereby improving uplink transmission performance.

[0016] In one possible implementation, the first data also includes data of a fourth logical channel; wherein the data of the fourth logical channel is determined based on at least the logical channel priority and the remaining transmission resources of the first uplink authorization, and the remaining transmission resources of the first uplink authorization are the transmission resources remaining after the first uplink authorization carries the data to be transmitted of the first logical channel or the data packet with the remaining time in the first logical channel less than or equal to the remaining time threshold. That is to say, based on the triggering time or sending time of the delay status report, when the transmission resources of the first uplink authorization are used to preferentially send all the data packets to be transmitted in the first logical channel configured with a discard timer or a remaining time threshold, or preferentially send the data packet with the remaining time in the first logical channel less than or equal to the remaining time threshold, if there are still remaining transmission resources in the first uplink authorization, the data to be transmitted is determined based on at least the logical channel priority and the remaining transmission resources, and the transmission resources of the first uplink authorization are fully utilized for uplink transmission, thereby improving the scheduling performance of uplink transmission.

[0017] In a second aspect, embodiments of the present application provide a communication processing method, which can be executed by a network device, or by a device compatible with the network device, such as a processor, chip, or chip module. The method may include: receiving first data; wherein the first data is transmitted using a first uplink granted transmission resource based on a trigger time or a send time of a delay status report; the first data is determined based on at least a remaining time of a data packet in a first logical channel of the terminal device, the first logical channel including a logical channel configured with a discard timer or a remaining time threshold, and the first data includes data of at least one first logical channel.

[0018] In which, the network device receives the first data, and the first data is sent using the first uplink authorization based on the trigger time or sending time of the delay status report and is determined at least based on the remaining time of the data packet in the first logical channel. For example, the data in the data packet with insufficient remaining time in the first logical channel is sent first, which avoids the data packet in the logical channel from being discarded due to failure to send, thereby improving the scheduling performance of the uplink transmission.

[0019] In one possible implementation, the first data is transmitted after the delay status report is sent. That is, after the terminal device sends the delay status report, the first data is transmitted, which reduces the processing complexity of the uplink transmission and improves the scheduling performance of the uplink transmission.

[0020] In one possible implementation, the first data is transmitted after the delay status report is sent and at a time interval of at least the first duration from the delay status report. That is, taking into account the uplink transmission delay of the delay status report and the scheduling delay of the network device in performing scheduling based on the delay status report, the first data is transmitted after waiting for at least the first duration after the terminal device sends the delay status report. This allows the network device to promptly schedule resources for the terminal device after obtaining the delay status report reported by the terminal device, that is, to allocate reasonable transmission resources to the terminal device, thereby facilitating the terminal device to send data packets with insufficient remaining time.

[0021] In one possible implementation, the first data is transmitted before the trigger time of the delay status report. That is, the first data is transmitted in advance before the trigger time of the terminal device sending the delay status report, so that the network device can parse the method by which the terminal device determines the first data based on the first data received from the terminal device, which is beneficial for the network device to reasonably allocate uplink resources to the terminal device, for example, allocating more uplink resources for transmitting delay-sensitive logical channels, thereby helping to reduce the triggering of the delay status report, which can effectively reduce the processing complexity of the terminal device and also help reduce the overhead of air interface signaling.

[0022] In one possible implementation, the first data is transmitted before a delay status report triggering time and at a time interval of at least a second duration from the delay status report triggering time. In other words, the first data is transmitted before the delay status report triggering time and at least the second duration in advance, so that there is sufficient time for transmission of the first data, which helps reduce the triggering or sending of the delay status report.

[0023] In a possible implementation, before receiving the first data, the method further includes: sending configuration information of the second duration.

[0024] In one possible implementation, after receiving the first data, the method further includes: receiving second data; wherein the second data is transmitted using a second uplink grant, and the second data is determined based at least on the priority of each logical channel. That is, if the remaining time of the data packets in the first logical channel is greater than or equal to the remaining time threshold, i.e., if there is sufficient time for the data packets in the first logical channel to be transmitted, the second data to be transmitted is determined based at least on the priority of each logical channel. This effectively and accurately switches between a method of determining data transmission based at least on the remaining time of the data packets in the first logical channel and a method of determining data transmission based at least on the priority of each logical channel, thereby improving the scheduling performance of uplink transmission.

[0025] In one possible implementation, before receiving the first data, the method further includes: sending downlink control signaling, the downlink control signaling being used to configure a first uplink grant; or sending a configuration grant, the configuration grant being used to configure the first uplink grant. In other words, the first uplink grant can be dynamically scheduled via downlink control signaling or semi-statically scheduled via the configuration grant.

[0026] In one possible implementation, the first data includes data in a third logical channel, the minimum remaining time of a data packet in the third logical channel is less than or equal to a remaining time threshold corresponding to the third logical channel, and the first logical channel includes the third logical channel. In other words, based on the triggering time or sending time of the delay status report, data packets whose minimum remaining time is less than or equal to the remaining time threshold are prioritized for transmission to avoid discarding these data packets, thereby improving uplink transmission performance.

[0027] In one possible implementation, the first data also includes data of a fourth logical channel; wherein the data of the fourth logical channel is determined based on at least the logical channel priority and the remaining transmission resources of the first uplink authorization, and the remaining transmission resources of the first uplink authorization are the transmission resources remaining after the first uplink authorization carries the data to be transmitted of the first logical channel or the data packet with the remaining time in the first logical channel less than or equal to the remaining time threshold. That is to say, based on the triggering time or sending time of the delay status report, after preferentially transmitting all the data packets to be transmitted in the first logical channel configured with a discard timer or a remaining time threshold using the transmission resources of the first uplink authorization, or preferentially transmitting the data packet with the remaining time in the first logical channel less than or equal to the remaining time threshold, if there are still remaining transmission resources in the first uplink authorization, the data to be transmitted is determined based on at least the logical channel priority and the remaining transmission resources, and the transmission resources of the first uplink authorization are fully utilized for uplink transmission, thereby improving the scheduling performance of uplink transmission.

[0029] A communication unit, configured to send first data using a first uplink authorized transmission resource based on a triggering time or a sending time of a delay status report; wherein the first data is determined based at least on the remaining time of a data packet in a first logical channel, the first logical channel includes a logical channel configured with a discard timer or a remaining time threshold, and the first data includes data of at least one first logical channel.

[0055] Secondly, the relevant concepts involved in the embodiments of this application are explained.

[0056] 1. Uplink resource allocation based on logical channel priority (LCP)

[0057] LCP-based uplink resource allocation refers to the method of allocating uplink grant (UL Grant) transmission resources for logical channels based on LCP processing. LCP in the New Radio (NR) communication system is similar to LTE (Long Term Evolution). The network (i.e., network equipment) allocates uplink transmission resources on a per-UE basis rather than a per-bearer basis. However, the terminal device determines which radio bearer data can be placed in the allocated uplink transmission resources for transmission.

[0058] Based on the uplink transmission resources configured by the network, the terminal device needs to determine the amount of data to be transmitted for each logical channel in the initial transmission of the Media Access Control Protocol Data Unit (MAC Protocol Data Unit, MAC PDU). In some cases, the terminal device also needs to allocate resources to the Media Access Control Control Element (MAC Control Element, MAC CE).

[0059] To achieve uplink logical channel multiplexing, each uplink logical channel must be assigned a priority. For a MAC PDU of a given size, if multiple uplink logical channels within the MAC PDU simultaneously require data transmission, the resources of the MAC PDU can be allocated sequentially based on the logical channel priorities corresponding to the aforementioned uplink logical channels, from highest to lowest.

[0060] At the same time, in order to take into account the fairness between different logical channels, the concept of Prioritized Bit Rate (PBR) is introduced. When the terminal device performs logical channel multiplexing, it needs to first ensure the minimum data rate requirement of each logical channel, so as to avoid the problem that the high-priority uplink logical channel always occupies the uplink resources allocated to the terminal device by the network, resulting in the terminal device's other low-priority uplink logical channels never being allocated resources.

[0061] Optionally, the LCP-based uplink resource allocation method includes: when the medium access control (MAC) layer of the terminal device receives one or more UL grants, the physical layer of the terminal device will tell the MAC layer the attributes of the UL grant; the terminal device determines which logical channels are related to each UL grant based on the attributes of each UL grant and the configuration of each logical channel, that is, determines the logical channels that can be transmitted through each UL grant; for multiple logical channels related to the same UL grant, the terminal device first allocates the transmission resources of the UL grant to the logical channels of corresponding priorities (for example, the highest priority) based on the priorities of each logical channel, at least based on the PBR of the logical channel; if the UL grant still has remaining transmission resources, the terminal device will allocate the remaining transmission resources to other logical channels related to the UL grant according to the priority of each logical channel until the transmission resources of the UL Grant are allocated.

[0062] Specifically, to achieve uplink logical channel multiplexing, the network device can configure the following parameters for each uplink logical channel through Radio Resource Control (RRC) information:

[0063] -Logical channel priority: The smaller the priority value, the higher the corresponding priority;

[0064] -PBR: indicates the minimum rate that the logical channel needs to guarantee;

[0065] - Bucket Size Duration (BSD): This parameter determines the depth of the token bucket.

[0066] The MAC layer of the terminal device uses the token bucket mechanism to implement uplink logical channel multiplexing. The terminal device maintains a token number variable B for each uplink logical channel j. j , this variable indicates the number of tokens currently available in the token bucket, and its maintenance method is as follows:

[0067] Step 1: When the terminal device establishes logical channel j, it initializes Bj is 0;

[0068] Step 2: Before each LCP process, the terminal device will j Increase PBR*T, where T is the last increase in B j The time interval from the moment to the current moment;

[0069] Step 3, if you follow step 2 to j Update, and the updated B j If it is greater than the maximum capacity of the token bucket (i.e. PBR*BSD), then B j The value is set to the maximum capacity of the token bucket.

[0070] Optionally, when the terminal device receives a newly transmitted UL Grant from the network device, the terminal device may perform logical channel priority processing according to the following steps:

[0071] S1. Determine which logical channels are related to the newly transmitted UL grant based on the attributes of the newly transmitted UL grant and the configuration of each logical channel, that is, determine the logical channels that can be transmitted through the newly transmitted UL grant. For example, the attributes of UL Grant include: subcarrier spacing and symbol length. When the subcarrier spacing configured for the logical channel is the same as or matches the subcarrier spacing configured for the UL Grant, and the symbol length allowed for transmission configured for the logical channel is the same as or matches the symbol length configured for the UL Grant, it is determined that the logical channel can be transmitted through the UL Grant.

[0072] S2, for B j > 0, the terminal device allocates resources to the logical channels associated with the UL grant in descending order of logical channel priority, using the uplink transmission resources given by the newly transmitted UL grant, i.e., the MAC PDU available for transmission determined in step S1. The resources allocated to each logical channel can only meet the PBR requirements of the logical channel. When the PBR of a logical channel is set to infinity, logical channels with lower logical channel priorities will be considered only after the resources of this logical channel are met.

[0073] S3, update the resources that can be allocated to the logical channel, that is, B j Subtract the size of all MAC service data units (SDUs) of logical channel j multiplexed into the MAC PDU in S1.

[0074] S4: If there are still uplink transmission resources left after executing S2 and S3, then regardless of B jThe remaining resources are allocated to the logical channels associated with the UL grant in descending order of logical channel priority. Low-priority logical channels are served only when all high-priority logical channels can carry data and the UL grant has not been exhausted. This allows the terminal device to maximize data transmission on high-priority logical channels.

[0075] At the same time, terminal devices should also follow the following principles when transmitting data using logical channel priorities:

[0076] Principle 1: If the entire Radio Link Control (RLC) SDU that the terminal needs to transmit can be filled into the remaining uplink transmission resources, the RLC SDU should not be segmented;

[0077] Principle 2: If the terminal device segments the RLC SDU in the logical channel, it should try to fill the largest segment possible based on the remaining transmission resources.

[0078] Principle 3: Terminal devices should maximize data transmission;

[0079] Principle 4: If the UL Grant size is greater than or equal to 8 bytes and the terminal device has data transmission requirements, the terminal device cannot send only a padding buffer status report (padding BSR) or only padding bits.

[0080] Optionally, for different signals and / or logical channels, when the terminal device performs logical channel priority processing, it is also necessary but not limited to following the following priority order processing (arranged in descending order of logical channel priority, this part may be updated later with the introduction of new MAC CE):

[0081] (1) Cell-Radio Network Temporary Identifier (C-RNTI) MAC CE or data from the uplink common control channel (UL-CCCH);

[0082] (2) Configured Grant Confirmation MAC CE;

[0083] (3) Used for BSR MAC CE except padding BSR;

[0084] (4) Single Entry Power Headroom Reporting (PHR) Media Access CE (MAC CE) or Multiple Entry Power Headroom Reporting (PHR) Media Access CE (MAC CE);

[0085] (5) Data from any logical channel except UL-CCCH;

[0086] (6) MAC CE for recommended bit rate query;

[0087] (7) BSR MAC CE for padding BSR.

[0088] 2. Remaining time of data packet

[0089] For a terminal device in a connected state, data transmission can begin after one or more data radio bearers (DRBs) are established. Figure 2 , Figure 2 A schematic diagram of a data packet arriving at layer 2 provided in an embodiment of the present application, namely Figure 2 The DRB mapped to a logical channel shows the situation of the data packet arriving at Layer 2 of the terminal device. When an uplink transmission data packet arrives at Layer 2 of the terminal device, if the data packet is not sent to the network within a preset time period, the terminal device will discard the uplink data packet. Optionally, for logical channels configured with a discard timer (DiscardTimer) or a remaining time threshold, the terminal device will record the DiscardTimer of each data packet in these logical channels, and the timing duration of the DiscardTimer will gradually decrease as time passes. The DiscardTimer of each data packet starts timing when the data packet arrives at Layer 2; and before the timing times out, if the data packet cannot be scheduled to be sent to the network, the data packet corresponding to the discard timer with the timed out will be discarded.

[0090] The remaining time of a packet is the remaining time of the corresponding discard timer. The minimum remaining time of a packet in a logical channel is the minimum remaining time of all packets in the logical channel, that is, the remaining time of the earliest packet arriving at Layer 2 in the logical channel.

[0091] Therefore, when the terminal device uses the above-mentioned LCP-based uplink resource allocation method to allocate the transmission resources of the UL Grant, it may result in the terminal device being unable to send the delay-sensitive data packet to be transmitted uplink to the network device within the preset time period after the data packet reaches layer 2 of the terminal device, and then the terminal device needs to discard the data packet, resulting in poor scheduling performance of the uplink transmission.

[0092] In view of this, an embodiment of the present application provides a communication processing method and a communication device, which can send first data determined at least based on the remaining time of the data packet in the logical channel based on the trigger time or sending time of the delay status report, thereby facilitating improving the scheduling performance of the uplink transmission.

[0093] The following is based on Figure 1 The system architecture shown in FIG. 1 is used to provide a detailed description of the resource determination method provided in the embodiments of the present application. The execution entities in the embodiments of the present application may be terminal devices and network devices. Alternatively, the execution entities in the embodiments of the present application may be devices that match the terminal devices, such as processors, chips, or chip modules, and devices that match the network devices, such as processors, chips, or chip modules. The following description uses terminal devices and network devices as examples.

[0094] See Figure 3 , Figure 3 A flow chart of a communication processing method provided in an embodiment of the present application is provided. The method may include but is not limited to the following steps:

[0095] 301. A network device sends a downlink control signaling to a terminal device, where the downlink control signaling is used to configure a first UL Grant; or, the network device sends a configuration authorization to the terminal device, where the configuration authorization is used to configure a first UL Grant. Accordingly, the terminal device receives the downlink control signaling; or, the terminal device receives the configuration authorization.

[0096] The terminal device may obtain the first UL Grant through downlink control signaling, ie, through dynamic scheduling, or may obtain the first UL Grant through configuration authorization, ie, through semi-persistent scheduling. One or more periodically occurring UL Grants may be obtained through semi-persistent scheduling.

[0097] Optionally, after the terminal device obtains the first UL Grant, the terminal device can determine the logical channel related to the first UL Grant based on the attributes of the first UL Grant and the configuration of each logical channel of the terminal device, that is, determine the logical channel that can be transmitted through the first UL Grant. Optionally, the attributes of the first UL Grant may include but are not limited to attributes such as subcarrier spacing and symbol length. For example, when the subcarrier spacing configured for the logical channel is the same as or matches the subcarrier spacing configured for the first UL Grant, and the symbol length allowed for transmission configured for the logical channel is the same as or matches the symbol length configured for the first UL Grant, it is determined that the logical channel can be transmitted through the first UL Grant.

[0098] 302. The terminal device transmits first data using the transmission resources of the first UL Grant based on the triggering time or sending time of the delay status report. The first data is determined based on at least the remaining time of the data packet in the first logical channel. The first logical channel includes a logical channel configured with a discard timer or a remaining time threshold. The first data includes data of at least one first logical channel. Accordingly, the network device receives the first data. The first data is transmitted using the transmission resources of the first UL Grant based on the triggering time or sending time of the delay status report. The first data is determined based on at least the remaining time of the data packet in the first logical channel of the terminal device. The first logical channel includes a logical channel configured with a discard timer or a remaining time threshold. The first data includes data of at least one first logical channel.

[0099] Among them, the first logical channel can have one or more logical channels, and each of the one or more logical channels is configured with a discard timer or a remaining time threshold (remainingTimeThreshold). The first logical channel is also a logical channel that can be transmitted through the first UL Grant, that is, the configuration of the first logical channel is related to or matches the attributes of the first UL Grant. The remaining time (remainingTime) of the data packet is the remaining time counted by the discard timer corresponding to the data packet, and the discard timer corresponding to the data packet starts counting when the data packet reaches layer 2. When the discard timer corresponding to the data packet times out, if the data packet is still not scheduled, the terminal device discards the data packet. The duration of the discard timer corresponding to different data packets or data packets in different logical channels can be the same or different. The remaining time thresholds configured for different logical channels can be the same or different.

[0100] In one implementation, before executing step 302, in response to the minimum remaining time of the data packet in the second logical channel being less than the remaining time threshold, a delay status report is triggered, the first logical channel includes the second logical channel, that is, the second logical channel is any logical channel in the first logical channel, and the remaining time threshold is the remaining time threshold corresponding to the second logical channel. In other words, the minimum remaining time of the data packet in any logical channel in the first logical channel is less than the remaining time threshold corresponding to the logical channel, and a delay status report (DSR) is triggered to report the minimum remaining time and data volume of the data packet to the network through DSR, that is, DSR is used by the terminal device to report the minimum remaining time and data volume of the data packet in the logical channel to the network device. The reporting of DSR facilitates timely scheduling of the network and avoids data packets being discarded due to excessive delays. Among them, the minimum remaining time of the data packet in the logical channel refers to the minimum remaining time of all the data packets in the logical channel, and can also be regarded as the remaining time of the earliest data packet that arrives at layer 2 among all the data packets in the logical channel.

[0101] Optionally, DSR is reported in the form of MAC CE. Specifically, the remaining time and buffer size can be reported according to the logical channel group (LCG). In some embodiments, the network will group logical channels with similar quality of service (QoS) into the same LCG. Figure 4 , Figure 4 This is a format of a DSR MAC CE provided in an embodiment of the present application. Figure 4 As shown, the MAC CE carrying DSR may include 2m+1 bytes (Oct), where m is a positive integer, and BT i (1≤i≤m) represents the corresponding logical channel group (e.g., LCG i ) Whether the cache size is indicated by the newly added cache table. If BT i is set to 1, it means that the cache size is indicated by the value in the new Table 6.1.3.1-3 of TS38.321; if BT i is set to 0, it means that the cache size is indicated by the value in the old Table 6.1.3.1-2 of TS38.321. R represents the reserved field, and the remaining time (Remain Time) i represents the LCG i The minimum remaining time of the data, the buffer size (buffer size) i represents LCG iThe amount of data to be transmitted in the DSR. When calculating the buffer size, the buffer size of the Packet Data Convergence Protocol (PDCP) control PDU and the retransmitted data packets can be calculated together. In other words, the buffer size reported in the DSR can be, for example, the size of a delay-critical data packet.

[0102] Optionally, assuming that there are 8 LCGs, respectively recorded as LCG0 to LCG7, that is, m=8, that is, the DSR MAC CE can configure a field for reporting for each LCG. In response to the logical channel (Logical Channel, LCH) in any of the 8 LCGs triggering the DSR report, the UE will report the delay status of all LCGs or the delay status of some LCGs (that is, only some LCGs have data packets with the remaining time lower than the corresponding remaining time threshold). Optionally, if the remaining time of the data of all logical channels in one of the 8 LCGs is greater than the remaining time threshold, the field corresponding to the LCG in the DSR MAC CE is empty.

[0103] The triggering time of DSR refers to the time when DSR sending is triggered. Optionally, the triggering time of DSR refers to the time when DSR starts to enter the state where it is allowed to send or the time when it is expected to start sending DSR. Optionally, when it is detected that the minimum remaining time of the data packet in the second logical channel is less than the remaining time threshold, DSR is triggered to trigger the sending of DSR at the triggering time of DSR, to make DSR enter the state where it is allowed to send or to start sending DSR. Optionally, the triggering time may be the time when it is detected that the minimum remaining time of the data packet in the second logical channel is less than the remaining time threshold, or the triggering time may be after the time when it is detected that the minimum remaining time of the data packet in the second logical channel is less than the remaining time threshold, which is not limited here.

[0104] Optionally, the sending time of DSR refers to the time when DSR is sent. The sending time of DSR is after the triggering time of DSR, and the sending time of DSR is determined based on the first UL Grant. Optionally, after the terminal device obtains the first UL Grant that can be used to send the first data, it needs to process the first data according to the transmission resources of the first UL Grant, for example, allocating the transmission resources of the first UL Grant to the first data, etc. This processing process takes a certain amount of time, and the processed first data can be sent through the transmission resources of the first UL Grant.

[0105] Optionally, in step 301, the terminal device may receive the downlink control signaling in step 301 within a short time range before and after the triggering time of the DSR, or the terminal device may receive the configuration authorization in step 301 before the triggering time of the DSR, or the terminal device may receive the configuration authorization in step 301 within a short time range after the triggering time of the DSR; wherein the first UL Grant configured by the downlink control signaling or the configuration authorization can be used to send the first data within a period of time after the triggering time of the DSR.

[0106] In step 302, the first data sent using the transmission resources of the first UL Grant is determined based at least on the remaining time of the data packet in the first logical channel of the terminal device, which means that the transmission resources of the first UL Grant are allocated to at least one first logical channel based at least on the remaining time of the data packet in the first logical channel of the terminal device for sending the first data, which is beneficial for giving priority to sending data packets with insufficient remaining time, avoiding discarding data packets with insufficient remaining time, and improving the scheduling performance of uplink transmission. This method of allocating resources for the transmission resources of the first UL Grant can be called a delay-based uplink resource allocation method, also known as a delay-based scheduling mechanism or a remaining time-based scheduling mechanism, or other names, which are not limited here.

[0107] Optionally, the terminal device can only execute step 302 if it supports the above-mentioned delay-based uplink resource allocation method and the network configures the terminal device to report DSR; otherwise, the terminal device can use LCP-based uplink resource allocation to allocate uplink transmission resources to the logical channel.

[0108] In one implementation, the first data sent by the terminal device based on the triggering time or sending time of the DSR includes data of at least one first logical channel, which may include but is not limited to the following:

[0109] In case 1, the first data includes partial data of a data packet in a first logical channel. For example, the transmission resources of the first UL Grant are limited and can only be used to transmit a small amount of data. That is, the transmitted first data is partial data in the data packet corresponding to the minimum remaining time in the second logical channel.

[0110] Case 2: The first data includes a data packet whose remaining time in the first logical channel is less than the remaining time threshold corresponding to the first logical channel. That is, the terminal device sends a data packet whose remaining time in the first logical channel is less than the remaining time threshold corresponding to the first logical channel based on the transmission resources of the first UL Grant. That is, the first UL Grant is only used to transmit a data packet whose remaining time in the logical channel is less than the remaining time threshold corresponding to the logical channel.

[0111] In case 3, the first data includes data to be transmitted on the first logical channel. For example, the first data includes all data to be transmitted on the first logical channel. Unlike case 2, in case 3, if the first UL Grant carries a data packet whose remaining time on the first logical channel is less than the remaining time threshold corresponding to the first logical channel, and there are still remaining transmission resources, the first UL Grant can also carry other data packets to be transmitted on the first logical channel, so as to be used for transmitting other data packets to be transmitted.

[0112] Case 4: The first data includes data in the third logical channel, the minimum remaining time of the data packet in the third logical channel is less than or equal to the remaining time threshold corresponding to the third logical channel, and the first logical channel includes the third logical channel. That is, the terminal device sends part or all of the data of one or more third logical channels based on the transmission resources of the first UL Grant. The data sent may include data in the data packet corresponding to the minimum remaining time in the third logical channel, that is, the data sent belongs to the data packet that arrives at layer 2 earliest in the third logical channel; and / or the data sent may also include data in the data packet corresponding to other remaining times in the third logical channel except the minimum remaining time.

[0113] Optionally, for case 2, the terminal device determines the first data based on the remaining time of the data packet in the first logical channel, that is, allocates the transmission resources of the first UL Grant based on the scheduling mechanism of the remaining time, which can be implemented in but not limited to the following ways:

[0114] The first method is to determine the first data to be sent using the first UL Grant based on the relative duration of the remaining times of the data packets in the first logical channel, that is, to allocate the transmission resources of the first UL Grant; wherein, the first logical channel with a shorter remaining time of the data packet or a shorter minimum remaining time is preferentially allocated the transmission resources of the first UL Grant.

[0115] Optionally, the first method may include: 51, the terminal device allocates the transmission resources of the first UL Grant to each first logical channel whose remaining time of the data packet or the minimum remaining time is less than the remaining time threshold according to the respective PBRs of the first logical channels, that is, allocates the respective PBRs to each first logical channel whose remaining time of the data packet or the minimum remaining time is less than the remaining time threshold.

[0116] After executing step 51, if the first UL Grant has remaining transmission resources, the first method may also include: 52, the terminal device allocates the remaining transmission resources to the first logical channel where the data packets whose remaining time or minimum remaining time is less than the remaining time threshold are located, and the first logical channel where the data packet whose remaining time or minimum remaining time is the smallest is located.

[0117] Among them, step 52 may include: if the remaining transmission resources are insufficient to transmit the data packet whose remaining time or the minimum remaining time is less than the remaining time threshold of the first logical channel in the first logical channel where the data packet is located, then the terminal device determines the data that can be transmitted in the first logical channel according to the amount of data that can be transmitted by the remaining transmission resources, thereby determining the first data sent through the first UL Grant, and the uplink transmission resource allocation is completed; or, if the remaining transmission resources are sufficient to transmit the data packet whose remaining time or the minimum remaining time is less than the remaining time threshold of the first logical channel in the first logical channel where the data packet is located, the remaining transmission resources are allocated to the first logical channel, wherein, if after the remaining transmission resources are allocated to the first logical channel, the first UL Grant has no other remaining transmission resources, then the uplink transmission resource allocation is completed, and the data allocated to the transmission resources of the first UL Grant is the first data sent through the first UL Grant, or, if after the remaining transmission resources are allocated to the first logical channel, the first UL Grant has other remaining transmission resources, then the other remaining transmission resources are further allocated.

[0118] After executing step 52, if the remaining transmission resources are sufficient to transmit the data packet whose remaining time or minimum remaining time is less than the remaining time threshold of the first logical channel in the first logical channel where the data packet whose remaining time or minimum remaining time is less than the remaining time threshold is located, and there are other remaining transmission resources for the first UL Grant, return to step 52, that is, the terminal device allocates the remaining transmission resources to the first logical channel where the data packet whose current remaining time or minimum remaining time is the smallest in each first logical channel where the data packet whose remaining time or minimum remaining time is less than the remaining time threshold is located, and re-executes this process of step 52 to exclude the first logical channel to which the transmission resources of the first UL Grant have been allocated.

[0119] For example, the terminal device establishes DRB1, DRB2, DRB3 and Signaling Radio Bearer (SRB) 1 and SRB2. Among them, DRB1 is mapped to LCH3, DRB2 is mapped to LCH4, DRB3 is mapped to LCH5, SRB1 is mapped to LCH1, and SRB2 is mapped to LCH2; the logical channel priority of LCH5 is higher than the logical channel priority of LCH4, and the logical channel priority of LCH4 is higher than or equal to the logical channel priority of LCH3; DRB1 is configured with the remaining time threshold 1, which can also be regarded as LCH3 is configured with the remaining time threshold 1; DRB2 is configured with the remaining time threshold 2, which can also be regarded as LCH4 is configured with the remaining time threshold 2. At time T1, the terminal device can use the first UL Grant for data transmission. At this time, the remaining time or minimum remaining time of the data in DRB1 is 10ms, which is less than the remaining time threshold 1 of DRB1. It can also be regarded as the remaining time or minimum remaining time of the data in LCH3 is 10ms, which is less than the remaining time threshold 1 of LCH3. The remaining time or minimum remaining time of the data in DRB2 is 20ms, which is less than the remaining time threshold 2 of DRB2. It can also be regarded as the remaining time or minimum remaining time of the data in LCH4 is 20ms, which is less than the remaining time threshold 2 of LCH4. It should be noted that the terminal device can receive the first UL Grant before time T1. In this example, the terminal device can prioritize allocating the transmission resources of the first UL Grant to the data in DRB1 with less remaining time or minimum remaining time, that is, the data in LCH3, and then allocate the transmission resources of the first UL Grant to the data in DRB2, that is, the data in LCH4.For example, the first UL Grant at time T1 can be used to transmit 1200 bits of data. The terminal device determines that the first UL Grant can transmit the data of DRB1 and the data of DRB2, that is, it can transmit the data in LCH3 and the data in LCH4. The terminal device can first allocate the corresponding PBRs to DRB1 and DRB2, that is, LCH3 and LCH4, that is, allocate the transmission resources of the first UL Grant according to DRB1 and DRB2, that is, LCH3 and LCH4, and the corresponding PBRs are DRB1 and DRB2, that is, LCH3 and LCH4; if the first UL Grant still has remaining transmission resources, that is, 1200 bits is greater than the sum of the PBRs allocated to DRB1 and DRB2 respectively, and the remaining transmission resources are preferentially allocated to the data of DRB1 with a smaller remaining time, that is, the data in LCH3; wherein, if the remaining transmission resources are insufficient to transmit the data packets in DRB1, that is, LCH3, with a remaining time less than the remaining time threshold 1, then the data that can be transmitted in the data packets in DRB1, that is, LCH3, with a remaining time less than the remaining time threshold 1 can be determined according to the number of bits that can be actually transmitted by the remaining transmission resources; if the remaining transmission resources can transmit the data packets in DRB1, that is, LCH3, with a remaining time less than the remaining time threshold 1, and there are other remaining transmission resources, then other remaining transmission resources can be allocated to DRB2, that is, LCH4, to transmit all or part of the data packets or part of the data packets in DRB2, that is, LCH4, with a remaining time less than the remaining time threshold 2.

[0120] In the second manner, in response to the situation where the minimum remaining time in each data packet of the first logical channel is the same, the terminal device allocates the transmission resources of the first UL Grant according to the priority of the logical channel.

[0121] Optionally, the second method may include: 61, the terminal device allocates the transmission resources of the first UL Grant to each first logical channel whose remaining time of the data packet or the minimum remaining time is less than the remaining time threshold according to the respective PBRs of the first logical channels, that is, allocates the respective PBRs to each first logical channel whose remaining time of the data packet or the minimum remaining time is less than the remaining time threshold.

[0122] After executing step 61, if the first UL Grant has remaining transmission resources, the first method may also include: 62, the terminal device allocates the remaining transmission resources to the first logical channel with the highest logical channel priority among the first logical channels where the data packets whose remaining time or minimum remaining time is less than the remaining time threshold are located.

[0123] Optionally, step 62 may include: if the remaining transmission resources are insufficient to transmit a data packet whose remaining time in the first logical channel with the highest logical channel priority is less than the remaining time threshold of the first logical channel, the terminal device determines the data that can be transmitted in the first logical channel according to the amount of data that can be transmitted by the remaining transmission resources, thereby determining the first data sent through the first UL Grant, and the uplink transmission resource allocation is completed; or, if the remaining transmission resources are sufficient to transmit a data packet whose remaining time in the first logical channel with the highest logical channel priority is less than the remaining time threshold of the first logical channel, the remaining transmission resources are allocated to the first logical channel, wherein, if after the remaining transmission resources are allocated to the first logical channel, the first UL Grant has no other remaining transmission resources, the uplink transmission resource allocation is completed, and the data allocated to the transmission resources of the first UL Grant is the first data sent through the first UL Grant, or, if after the remaining transmission resources are allocated to the first logical channel, the first UL Grant has other remaining transmission resources, the other remaining transmission resources are further allocated.

[0124] After executing step 62, if the remaining transmission resources are sufficient to transmit the data packets whose remaining time is less than the remaining time threshold of the first logical channel in the first logical channel with the highest current logical channel priority, and the first UL Grant has other remaining transmission resources, return to step 62, that is, the terminal device allocates the remaining transmission resources to the first logical channel with the highest current logical priority among the first logical channels where the data packets whose remaining time or minimum remaining time is less than the remaining time threshold are located, and re-executes the process of step 62 to exclude the first logical channel to which the transmission resources of the first UL Grant have been allocated.

[0125] For example, the terminal device establishes DRB1, DRB2, DRB3, and Signaling Radio Bearer (SRB) 1 and SRB2. Among them, DRB1 is mapped to LCH3, DRB2 is mapped to LCH4, DRB3 is mapped to LCH5, SRB1 is mapped to LCH1, and SRB2 is mapped to LCH2; the logical channel priority of LCH5 is higher than the logical channel priority of LCH4, and the logical channel priority of LCH4 is higher than the logical channel priority of LCH3; DRB1 is configured with the remaining time threshold 1, which can also be regarded as LCH3 is configured with the remaining time threshold 1; DRB2 is configured with the remaining time threshold 2, which can also be regarded as LCH4 is configured with the remaining time threshold 2. At time T1, the terminal device can use the first UL Grant to transmit data. At this time, the remaining time or minimum remaining time of the DRB1 data is 20ms, which is less than the remaining time threshold 1 of DRB1. It can also be regarded as the remaining time or minimum remaining time of the LCH3 data is 20ms, which is less than the remaining time threshold 1 of LCH3. The remaining time or minimum remaining time of the DRB2 data is 20ms, which is less than the remaining time threshold 2 of DRB2. It can also be regarded as the remaining time or minimum remaining time of the LCH4 data is 20ms, which is less than the remaining time threshold 2 of LCH4. In this example, the terminal device can prioritize the data of DRB2 with a higher logical channel priority, that is, allocate resources for the data of LCH4, and then allocate resources for the data of DRB1, that is, the data of LCH3.For example, the first UL Grant at time T1 can be used to transmit 1000 bits of data. The terminal device determines that the first UL Grant can transmit the data of DRB1 and the data of DRB2, that is, it can transmit the data in LCH3 and the data in LCH4. The terminal device can first allocate the corresponding PBRs to DRB1 and DRB2, that is, LCH3 and LCH4, that is, allocate the transmission resources of the first UL Grant according to DRB1 and DRB2, that is, LCH3 and LCH4, and the corresponding PBRs are DRB1 and DRB2, that is, LCH3 and LCH4; if the first UL Grant still has remaining transmission resources, that is, there are remaining transmission resources after deducting the PBR of DRB1 and DRB2 respectively from 1000 bits, and the remaining transmission resources are preferentially allocated to DRB2, that is, LCH4; wherein, if the remaining transmission resources are insufficient to transmit the data packets in DRB2, that is, LCH4, with the remaining time less than the remaining time threshold 2, the data packets in DRB2, that is, LCH4, with the remaining time less than the remaining time threshold 2 can be determined according to the number of bits that can be actually transmitted by the remaining transmission resources; if the remaining transmission resources can transmit the data packets in DRB2, that is, LCH4, with the remaining time less than the remaining time threshold 2, and there are other remaining transmission resources, then other remaining transmission resources can be allocated to DRB1, that is, LCH3, to transmit all or part of the data packets or part of the data packets in DRB1, that is, LCH3, with the remaining time less than the remaining time threshold 1.

[0126] It should be noted that in the first and second methods, when the terminal device allocates the transmission resources of the first UL Grant based on the scheduling mechanism of the remaining time, the terminal device will not allocate uplink transmission resources to the SRB to transmit the SRB data to be transmitted when allocating uplink transmission resources, that is, when the terminal device has SRB data to be transmitted, the terminal device will not allocate the transmission resources of the first UL Grant to the SRB.

[0127] In the third method, the terminal device preferentially allocates the transmission resources of the first UL Grant to the SRB. If there are remaining transmission resources of the first UL Grant after allocating the transmission resources of the first UL Grant to the SRB, the first data to be sent using the first UL Grant is determined based on the relative duration of the remaining times of the data packets in the first logical channel, that is, the transmission resources of the first UL Grant are allocated; wherein, the first logical channel with the shorter remaining time of the data packet or the shorter minimum remaining time is preferentially allocated the transmission resources of the first UL Grant. For the implementation method of determining the first data to be sent using the first UL Grant based on the relative duration of the remaining times of the data packets in the first logical channel, please refer to the first method and will not be elaborated here.

[0128] Optionally, in the third manner, the SRB to which the transmission resources of the first UL Grant are preferentially allocated may be one or more SRBs, for example, SBR1, or SBR1 and SBR2, or SBR1, SBR2 and SBR4.

[0129] In a fourth manner, the terminal device allocates transmission resources to the first logical channel with a high logical channel priority based on the logical channel priority of the first logical channel.

[0130] Among them, multiple first logical channels all have remaining time for data packets or the minimum remaining time is less than the remaining time threshold. At this time, when allocating uplink transmission resources, the terminal device allocates the transmission resources of the first UL Grant in sequence according to the logical channel priority from high to low. For example, when allocating the transmission resources of the first UL Grant, the PBRs of the aforementioned multiple first logical channels are first satisfied, so that each first logical channel is allocated its own PBR based on the transmission resources of the first UL Grant. This step can be referred to step 51 or step 61 and will not be repeated here; then, if there are remaining transmission resources for the first UL Grant, the remaining transmission resources are allocated to the multiple first logical channels in sequence according to the logical channel priority of the aforementioned multiple first logical channels from high to low.

[0131] In another implementation, the first data may include data of a fourth logical channel in addition to data of at least one first logical channel.

[0132] The data of the fourth logical channel is determined based on at least the logical channel priority and the remaining transmission resources of the first UL Grant. The remaining transmission resources of the first UL Grant are the transmission resources remaining after the first UL Grant carries the data to be transmitted of the first logical channel or the data packet in the first logical channel whose remaining time is less than or equal to the remaining time threshold. The fourth logical channel and the first logical channel can be different logical channels. For example, the first logical channel is a logical channel configured with a discard timer, and the fourth logical channel is a logical channel not configured with a discard timer; or for example, the first logical channel is a logical channel configured with a remaining time threshold, and the fourth logical channel is a logical channel not configured with a remaining time threshold. After sending the data to be transmitted of the first logical channel based on the transmission resources of the first UL Grant (i.e., case 3) or after sending a data packet with a remaining time less than or equal to the remaining time threshold in the first logical channel based on the transmission resources of the first UL Grant (i.e., case 2), if there are remaining transmission resources of the first UL Grant that have not been used for transmission, the remaining transmission resources of the first UL Grant can be allocated to the data of the fourth logical channel based on at least the logical channel priority, so as to be used for sending the data of the fourth logical channel. For example, the remaining transmission resources of the first UL Grant can be allocated to the data of the fourth logical channel by using the uplink resource allocation method based on LCP in the aforementioned related concepts. The data of the fourth logical channel sent can be all the data to be transmitted or part of the data to be transmitted in one or more fourth logical channels.

[0133] Step 302 may include but is not limited to the following two implementations:

[0134] Method 1: After the DSR sending time, the terminal device uses the transmission resources of the first UL Grant to send the first data.

[0135] After the sending time of DSR, if the terminal device has a first UL Grant that can be used to transmit the first data of the first logical channel, the first data will be sent using the transmission resources of the first UL Grant, that is, the first data will be transmitted after the sending time of DSR, which reduces the processing complexity of the terminal device and improves the scheduling performance of uplink transmission.

[0136] In one implementation, method 1 may include: the terminal device sends the first data using the transmission resources of the first UL Grant after the sending time of the DSR and when the time interval between the sending time of the DSR is at least a first duration.

[0137] Taking into account the uplink transmission delay of DSR and the scheduling delay of the network device according to DSR, if there is a first UL Grant that can be used to transmit the first data of the first logical channel after the sending time of DSR and the time interval between the sending time of DSR is at least the first time interval, the terminal device uses the transmission resources of the first UL Grant to send the first data, that is, waits for at least the first time interval after the terminal device sends DSR, for example, waits for at least 2 symbol lengths or 2 time slots, and then sends the first data, that is, the first data is transmitted after the sending time of DSR and the time interval between the sending time of DSR is at least the first time interval, so that the network device can promptly schedule resources for the terminal device after obtaining the DSR reported by the terminal device, that is, allocates reasonable transmission resources to the terminal device, so as to facilitate the terminal device to send data packets with insufficient remaining time.

[0138] In another implementation, method 1 may also include: after the DSR sending time, the terminal device can use the transmission resources of the first UL Grant to send the first data, that is, applying a delay-based scheduling mechanism or a remaining time-based scheduling mechanism for the first UL Grant. Optionally, this implementation can be understood as the first duration being 0.

[0139] Optionally, the first duration can be predefined in the terminal device or protocol. For example, the first duration is determined taking into account the transmission delay of the DSR and the scheduling delay of the network device according to the DSR, and the first duration is predefined in the terminal device. For example, the first duration is defined in the corresponding protocol. Other methods can also be used to configure the first duration, which are not limited here.

[0140] In one implementation, if the first UL Grant adopts dynamic scheduling, the network device can indicate in the downlink control signaling to apply a delay-based uplink resource allocation method, and the terminal device allocates the uplink transmission resources of the first UL Grant based on at least the remaining time of the first logical channel according to the indication in the downlink control signaling.

[0141] Method 2: Before the DSR is triggered, the terminal device uses the transmission resources of the first UL Grant to send the first data.

[0142] Before the triggering time of DSR (that is, the DSR is expected to be triggered soon), if the terminal device has a first UL Grant that can be used to transmit the first data of the first logical channel, the terminal device uses the transmission resources of the first UL Grant to send the first data, that is, the first data is transmitted before the triggering time of DSR, which is conducive to timely sending of data packets with insufficient remaining time, and the network device can parse the way in which the terminal device determines the first data based on the first data received from the terminal device, that is, determine the way in which the terminal device allocates resources to the transmission resources of the first uplink authorization, which is conducive to the network device reasonably allocating uplink resources to the terminal device, for example, allocating more uplink resources for transmitting delay-sensitive logical channels, thereby helping the terminal device to reduce the triggering of DSR, can effectively reduce the processing complexity of the terminal device, and also help to reduce the overhead of air interface signaling.

[0143] In one implementation, method 2 may include: the terminal device uses the transmission resources of the first UL Grant to send the first data before the triggering time of the DSR and when the time interval between the triggering time of the DSR is at least a second duration.

[0144] Before the triggering time of DSR and at least in advance for a second time period, for example, at least 5 ms or 5 time slots in advance, if there is a first UL Grant that can be used to transmit the first data of the first logical channel, the terminal device sends the first data using the transmission resources of the first UL Grant, that is, the first data is transmitted before the triggering time of DSR and at least in advance for a second time period before the triggering time of DSR, so that the terminal device has sufficient time to send the first data, which is conducive to reducing the triggering or sending of DSR.

[0145] Optionally, the second duration is configured by the network. For example, before executing step 302, the network device sends configuration information about the second duration to the terminal device; in response, the terminal device receives the configuration information about the second duration and obtains the second duration based on the configuration information to execute step 302. The second duration can also be configured in other ways, which are not limited here.

[0146] In one implementation, after first data is sent using the transmission resources of the first UL Grant based on mode 2, the DSR is canceled in response to the remaining time of the data packet in the second logical channel being greater than or equal to the remaining time threshold.

[0147] Before the triggering time of DSR, the terminal device detects that the remaining time of all data packets in the second logical channel is greater than or equal to the remaining time threshold, and determines that the data with a remaining time less than the remaining time threshold in the logical channel (i.e., the second logical channel) where the data packet corresponding to the minimum remaining time for triggering DSR is located has been sent using the first UL Grant. There is currently no data packet with insufficient remaining time on the second logical channel, and there is no need to report DSR to the network device so that the network device can adjust to the resources scheduled by the terminal device. In this case, DSR is canceled, that is, DSR reporting to the network device is not started at the triggering time and / or sending time of the delay status report, thereby reducing the processing overhead of DSR.

[0148] 303. In response to the remaining time of the data packet in the first logical channel being greater than or equal to the remaining time threshold, the terminal device uses a second UL Grant to send second data, where the second data is determined based at least on the priority of each logical channel. Correspondingly, the network device receives the second data, where the second data is transmitted using the second UL Grant in response to the remaining time of the data packet in the first logical channel of the terminal device being greater than or equal to the remaining time threshold; the second data is determined based at least on the priority of each logical channel of the terminal device.

[0149] After the terminal device sends the first data, if the remaining time of all data packets in the first logical channel that records the remaining time of the data packets is greater than or equal to the remaining time threshold, that is, the remaining time of the data packets in the first logical channel is sufficient, it can switch from a method of allocating the transmission resources of the first UL Grant based at least on the remaining time of the data packets in the first logical channel to a method of allocating the transmission resources of the second UL Grant based at least on the priority of each logical channel. For example, the uplink resource allocation method based on LCP in the aforementioned related concept can be used to allocate the transmission resources of the second UL Grant to each logical channel, so as to use the transmission resources of the second UL Grant to transmit the second data in each logical channel, which will not be elaborated here.

[0150] Among them, if all the data to be transmitted in the first logical channel has been sent using the transmission resources of the first UL Grant, the second data is all or part of the data of one or more logical channels in each logical channel except the first logical channel. If after the first data is transmitted using the transmission resources of the first UL Grant, there is still data to be transmitted in the first logical channel that has not been sent, the second data is all or part of the data of one or more logical channels in each logical channel, which may include the first logical channel.

[0151] Optionally, before executing step 303, the network device may send downlink control signaling or configuration authorization to the terminal device for configuring the second UL Grant. That is, the second UL Grant may be obtained through dynamic scheduling via downlink control signaling or semi-static scheduling via configuration authorization. After obtaining the first UL Grant, the terminal device obtains the second UL Grant.

[0152] Optionally, before executing step 302, the terminal device may use a third UL Grant to send third data, where the third data is determined at least based on the priority of each logical channel. For example, the uplink resource allocation method based on LCP in the aforementioned related concept is used to allocate the transmission resources of the third UL Grant to each logical channel, so as to use the transmission resources of the third UL Grant to transmit the third data in each logical channel. Details are not given here. Accordingly, the network device receives the third data, where the third data is determined at least based on the priority of each logical channel of the terminal device.

[0153] In which, when using the third UL Grant to send the third data, the terminal device can receive downlink control signaling or configuration authorization for configuring the third UL Grant. That is, the third UL Grant can be obtained through dynamic scheduling of downlink control signaling or semi-static scheduling through configuration authorization. The terminal device obtains the third UL Grant before obtaining the first UL Grant. The third data can be all or part of the data in one or more data packets in one or more logical channels of each logical channel.

[0154] The terminal device can determine the transmitted data based on the priority of each logical channel at least before and after using the first UL Grant to send the first data based on the trigger time or sending time of the DSR, that is, before and after allocating uplink transmission resources to the logical channel using the delay-based uplink resource allocation method, it is beneficial to allocate uplink transmission resources to the logical channel based on the LCP uplink resource allocation method.

[0155] exist Figure 3 In the embodiment shown, the terminal device uses the first UL Grant to send the first data to the network device based on the triggering time or sending time of the delay status report, which is determined at least based on the remaining time of the data packet in the logical channel, thereby avoiding the data packet in the logical channel from being discarded due to failure to send, and improving the scheduling performance of the uplink transmission.
