Description

Information transmission control method, device, communication equipment and storage medium

Technical Field

The present disclosure relates to the field of wireless communication technology but is not limited to the field of wireless communication technology, and in particular to an information transmission control method, device, communication equipment and storage medium.

Background technique

For services with multiple data streams, such as Extended Reality (XR) services, data is usually composed of multiple flows (QoS flows). The data streams of such services need to meet certain latency requirements during transmission. For example, there are multiple data streams that need to arrive at the server for decoding at the same time. In some cases, even if some data streams belong to low-priority logical channels (LC), if some data packets have not been scheduled for a long time, a buffer status report (BSR) still needs to be sent to notify the network as soon as possible.

However, in the related art, for data transmission scheduling between this type of LC and other LCs, for example, multiplexing and sending of this type of logical channel and other logical channels, there is often a mechanism in which BSR transmission is affected by delayed SR transmission of other LCs.

Summary of the invention

Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of terminals 11 and a plurality of access devices 12.

Among them, the terminal 11 can be a device that provides voice and/or data connectivity to the user. The terminal 11 can communicate with one or more core networks via a radio access network (RAN). The terminal 11 can be an Internet of Things terminal, such as a sensor device, a mobile phone (or a "cellular" phone), and a computer with an Internet of Things terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-built-in or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user device, a user agent, a user device, or a user terminal (user equipment, terminal). Alternatively, the terminal 11 can also be a device of an unmanned aerial vehicle. Alternatively, the terminal 11 can also be a vehicle-mounted device, for example, it can be a driving computer with wireless communication function, or a wireless communication device connected to an external driving computer. Alternatively, the terminal 11 may also be a roadside device, for example, a street lamp, a traffic light or other roadside device with a wireless communication function.

The access device 12 may be a network side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network). Alternatively, an MTC system.

Among them, the access device 12 can be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 can also be an access device (gNB) adopting a centralized distributed architecture in a 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (central unit, CU) and at least two distributed units (distributed units, DU). The centralized unit is provided with a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a media access control (Media Access Control, MAC) layer protocol stack; the distributed unit is provided with a physical (Physical, PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the access device 12.

A wireless connection can be established between the access device 12 and the terminal 11 through a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

Optionally, the wireless communication system may further include a network management device 13. Several access devices 12 are respectively connected to the network management device 13. The network management device 13 may be a core network device in the wireless communication system, for example, the network management device 13 may be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the network management device may also be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF) or a home subscriber server (HSS). The embodiment of the present disclosure does not limit the implementation form of the network management device 13.

As shown in FIG. 2 , an embodiment of the present disclosure provides an information transmission control method, which is executed by a network device. The method may include:

S110: Sending a reporting rule based on at least one LCG among multiple LCGs to the terminal, wherein the reporting rule at least instructs the terminal to report the BSR and/or SR through at least one LCG; and the SR is associated with the BSR.

In the disclosed embodiment, the network device may be a base station or other device on the network side, and the terminal may be a user equipment (UE), etc. The logical channel group LCG may include one or more logical channels LC, and the LC is used to transmit data of a service to be processed, such as an XR service.

Here, BSR and SR are information sent by the terminal to the base station when it needs to request scheduling data, and are used to notify and instruct the base station to schedule data transmission. For example, when the uplink transmission (UL) data of the LC belonging to an LCG is available, and the priority of the LC is higher than the priority of any LC containing available UL data belonging to any LCG, or other LCs belonging to the LCG do not contain any available UL data, the reporting of BSR is triggered.

In one embodiment, the BSR may include a regular BSR, a periodic BSR, or a padding BSR, etc., which are triggered when new data arrives or a higher priority LC arrives. If the periodic BSR times out and is not responded to, it is sent periodically. If authorization is not obtained within the predetermined time window, the BSR can be sent repeatedly. During the BSR transmission process, if authorization is not obtained, the reporting of the SR can be triggered, and the reporting time of the SR is limited by the delay time of the SR.

In one embodiment, the SR associated with the BSR may be a scheduling request sent by the terminal to the base station when the BSR report fails or the transmission scheduling requested by the BSR fails after the BSR report is triggered. For example, when a BSR is triggered and there is no uplink shared channel (UL-SCH) resource available for new transmission; or the Medium Access Control (MAC) entity configures an uplink grant of the configured grant type and the LogicalChannelSR-Mask parameter is false; or the UL-SCH resources available for new transmission do not meet the Logical Channel Prioritization (LCP) mapping restrictions configured for the LC that triggers the BSR, the reporting of the scheduling request SR is triggered.

In the related technology, when BSR and/or SR are reported through multiple multiplexed LCGs, the SR delayed sending mechanism configured by other multiplexed LCGs often affects the target LCG that is not configured with the SR delayed sending mechanism, resulting in the target LCG that needs to send urgent data also having to go through the same SR delayed sending period before the SR report can be reported, causing the urgent data to be unable to be sent in time.

In one embodiment, the reporting rules may include reporting rules for reporting BSR and/or SR through multiple multiplexed LCGs. For example, the reporting rules may include: reporting rules for SR when there is at least one LCG in the multiple multiplexed LCGs configured with an SR delayed sending mechanism, etc.

In one embodiment, LCG may configure an SR delayed sending mechanism, which corresponds to an SR delay timer (LogicalChannelSR-DelayTimer). The mechanism may instruct the terminal to report SR after the SR delay sending time corresponding to the SR delay timer has elapsed after the SR report is triggered.

In one embodiment, at least one LCG among the multiple LCGs may be an LCG used by the terminal to transmit data, for example, the number of at least one LCG or the number of LCs included in at least one LCG may be related to the number of data streams to be transmitted. Exemplarily, the number of data streams to be transmitted may be equal to the number of LCs included in at least one LCG.

In one embodiment, the reporting rule may indicate that when there is a predetermined type of data to be transmitted in the terminal or at least one LC, the BSR and/or SR is reported through at least one LCG. For example, the predetermined type of data to be transmitted may be data whose urgency reaches a predetermined standard or is not scheduled for transmission within a predetermined time period.

The predetermined type may also indicate other service characteristics of specific data, such as the importance of the data. For example, if I frame data is more important than P frame data and needs to be sent in time, the I frame data may be data to be transmitted of the predetermined type.

In this way, by sending reporting rules to the terminal, the terminal can be instructed to report through one or more LCGs, which improves the cooperation flexibility of multiplexing transmission between multiple LCGs. When there is data that needs to be notified as soon as possible through BSR or SR, the reporting rules can be used to reduce the mutual influence of different mechanisms between multiple LCGs and improve the transmission efficiency of emergency data. For multiple data streams contained in services such as XR, sending through multiple LCGs can improve the transmission success rate and optimize the service implementation effect.

As shown in FIG3 , an embodiment of the present disclosure provides an information transmission control method, which is executed by a network device. The method may include:

S210: Send a reporting rule based on at least one LCG among multiple LCGs to the terminal, wherein the reporting rule at least indicates that when there is at least one LCG among the multiple LCGs that meets the BSR triggering condition, the terminal reports the BSR and/or SR through a target LCG among the at least one LCG; the SR is associated with the BSR.

In the embodiment of the present disclosure, the BSR triggering condition may include at least one of a regular BSR, a periodic BSR, and a padding BSR. For example, the BSR triggering condition may include the presence of a predetermined type of data to be transmitted, or reaching the reporting period of a triggered periodic BSR, or a triggering condition of a regular BSR, etc.

In one embodiment, when at least one LCG meets the BSR triggering condition, the BSR and/or SR may be reported through a target LCG in at least one LCG. For example, a target LCG may be an LCG in at least one LCG that is not configured with an SR delay sending mechanism, or may be a target LCG indicated by a base station or negotiated between the terminal and the base station or determined according to a protocol, or may be a target LCG specified by the terminal, for example, determined according to the occupancy of LCs in the LCG and/or the number of LCs.

In one embodiment, when multiple LCGs meet the BSR triggering conditions, the BSR and/or SR is reported only through one target LCG, that is, the BSR only carries a single target LCG report, and there is no need to report the BSR together with other LCGs, thereby reducing the impact of other multiplexed LCGs on the target LCG.

In one embodiment, when multiple LCGs meet the BSR triggering conditions, the BSR and/or SR are reported only through one target LCG or one target LC, that is, the BSR only carries a single target LC report, thereby reducing the impact of other multiplexed LCGs or LCs on the target LCG or target LC.

In one embodiment, reporting the BSR and/or SR through a target LCG in at least one LCG may include: reporting the BSR and/or SR through one or more target LCs in a target LCG in at least one LCG. The target LC may be an LC in the LCG that is not configured with an SR delay sending mechanism, or may be a target LC indicated by a base station or negotiated between the terminal and the base station or determined according to a protocol, or may be a target LC specified by the terminal, for example, determined according to the occupancy of the LC in the LCG and/or the number of LCs.

In one embodiment, reporting BSR and/or SR through a target LCG in at least one LCG may include: reporting BSR and/or SR through a target LCG in at least one LCG and at least one associated LCG; the associated LCG is an LCG for delayed sending of an unconfigured SR multiplexed with the target LCG.

In one embodiment, the associated LCG multiplexed with the target LCG may be an LCG that is not configured with or does not have the SR delayed sending function enabled. Exemplarily, when there are three LCGs (LCG1, LCG2, LCG3) that meet the BSR triggering conditions, LCG1 that is not configured with SR delayed sending may be indicated to be multiplexed with LCG2, that is, when reporting the BSR, it may only carry the data of LCG1 and LCG2, and LCG3 that is configured with SR delayed sending may perform no data processing or not report. In this way, LCG1 and LCG2 can be sent as quickly as possible because there is no SR delayed sending mechanism configured. On the contrary, if the report is multiplexed with LCG3, and LCG3 is configured with a delayed sending mechanism, it will cause a delay in the SR reporting of the BSR.

In one embodiment, reporting the BSR and/or SR through a target LCG in at least one LCG and at least one associated LCG may include: when a target LCG in at least one LCG has data of a predetermined type to be transmitted, reporting the BSR and/or SR through the target LCG and at least one associated LCG. The associated LCG may be a specified LCG for which SR delay transmission is not configured.

In one embodiment, when there is a LC in the target LCG and the remaining delay budget of the data corresponding to the LC is lower than a predetermined threshold, the terminal determines that there is a predetermined type of data to be transmitted in the target LCG. The data is the data to be transmitted and/or being transmitted by the LC, and the remaining delay budget can be the remaining data delay budget corresponding to the remaining data to be transmitted in the LC.

In one embodiment, when a target LCG in at least one LCG has data to be transmitted of a predetermined type, the BSR and/or SR is reported through the target LCG and at least one associated LCG; when the target LCG does not have data to be transmitted of the predetermined type, the BSR and/or SR can be reported multiplexed with any other LCG. In this way, through the dynamically effective reporting rules, only when there is data to be transmitted of the predetermined type, the report is multiplexed with the designated associated LCG, thereby improving the flexibility of information transmission in the LCG.

In this way, after triggering the BSR report, controlling the BSR and/or SR reporting behavior of one or more LCGs can further improve the control accuracy of the BSR and/or SR reporting, thereby improving the transmission efficiency of the urgent data to be transmitted.

In some embodiments, reporting the BSR and/or SR through a target LCG in at least one LCG may include:

When there is at least one LC and/or LCG with the SR delayed sending function enabled in at least one LCG, the SR delayed sending function is stopped and the SR is reported.

In an embodiment of the present disclosure, when the target LCG does not have the SR delayed sending function turned on, if there is at least one other LCG that triggers the BSR report and has the SR delayed sending function turned on, the SR delayed sending function of the other LCG is stopped.

In one embodiment, stopping the SR delayed sending function and reporting the SR may include: if the SR triggering condition is met, stopping the SR delayed sending function and reporting the SR.

In one embodiment, when a target LC in a target LCG meets the BSR triggering condition, and at least one other LC or LCG that meets the BSR triggering condition has the SR delayed sending function enabled, the SR delayed sending timer enabled in the other LC or LCG is stopped and the SR is reported.

In one embodiment, the stopped SR delay sending timer, that is, the invalid SR delay sending timer, also indicates that the LC and/or LCG to process the scheduled service will not trigger the start of the SR delay sending timer even if the LogicalChannelSR-DelayTimerApplied parameter is configured.

In one embodiment, reporting the SR may be reporting the SR through the target LCG, or reporting the SR through the multiplexing of the target LCG and at least one LCG with the SR delay sending function stopped, for example, reporting the SR through the target LC in the target LCG and at least one associated LC in the associated LCG with the SR delay sending function stopped. The associated LC is an LC multiplexed with the target LC, for example, it may be a designated LC that is not configured with SR delay sending.

In one embodiment, stopping the SR delayed sending function may be stopping the SR delayed sending function in the current SR reporting cycle, or stopping the SR delayed sending function in a preset time period. After the current SR reporting cycle or the preset time period ends, the SR delayed sending function is restored.

In one embodiment, stopping the SR delay sending function and reporting the SR may include: if the BSR reporting is not authorized, stopping the SR delay sending function and reporting the SR.

In this way, by stopping the SR delay sending function of other LCGs that are multiplexed or stopping the running SR delay sending timer triggered by other LCGs, BSR can be reported in time. This can reduce the impact of multiplexed LCGs on the LCGs that are used to transmit the SR corresponding to the urgent data, and avoid unnecessary delays in the SR reporting of LCGs, which may cause the urgent data to be unable to be transmitted immediately.

In some embodiments, stopping the SR delay sending function and reporting the sending SR includes:

When a target LCG in at least one LCG has data of a predetermined type to be transmitted, the SR delayed sending function is stopped and the SR is reported.

In the embodiment of the present disclosure, the predetermined type of data to be transmitted may be data to be transmitted whose urgency reaches a predetermined standard or is not scheduled for transmission within a predetermined time period.

In one embodiment, when there is a remaining delay budget of data corresponding to an LC in the target LCG and the remaining delay budget is lower than a predetermined threshold, the terminal may determine that there is data of a predetermined type to be transmitted in the target LCG.

In an embodiment, a target LCG has data to be transmitted of a predetermined type, and at least one LC in the target LCG has data to be transmitted of a predetermined type.

In some embodiments, the reporting rule further instructs the terminal to determine that there is data of a predetermined type to be transmitted in the target LCG when there is a data corresponding to an LC in the target LCG and the remaining delay budget is lower than a predetermined threshold.

In some embodiments, the reporting rule further instructs the terminal:

Determine a target LC and/or a target LCG for a predetermined service to be processed in at least one LCG;

Set the target SR delay sending duration when the target LC and/or target LCG processes the scheduled service.

In the embodiment of the present disclosure, the SR delay transmission duration may indicate that the SR is transmitted after the SR delay transmission duration after the first scheduled time. For example, the first scheduled time may be the time when the SR report is triggered, or the time when the previous SR is transmitted, etc. The scheduled service may be a specified service type such as an XR service, etc. The scheduled service may also be a service corresponding to the predetermined type of data to be transmitted, for example, the predetermined type of data to be transmitted is generated by the scheduled service.

In one embodiment, setting the target SR delay sending duration when the target LC and/or target LCG processes the scheduled service may include: setting a first SR delay sending duration for the target LC and/or target LCG that processes the scheduled service; and setting a second SR delay sending duration for the target LC and/or target LCG corresponding to non-scheduled services, such as service types other than XR services. At this time, the first SR delay sending duration may be set to be less than the second SR delay sending duration. In this way, the target LC and/or target LCG of the scheduled service can wait for a shorter delay time when the BSR report needs to trigger the SR, so as to achieve more timely reporting.

In one embodiment, a logical channel SR delay sending timer (LogicalChannelSR-DelayTimer) may be configured separately for the XR service.

In one embodiment, a LogicalChannelSR-DelayTimer may be configured separately for an XR service, and the value of the LogicalChannelSR-DelayTimer may be smaller than the LogicalChannelSR-DelayTimer configured for a non-XR service.

In one embodiment, the method further includes: obtaining a preset SR delay transmission duration corresponding to at least one LC or LCG. Then the set target SR delay transmission duration may be less than the preset SR delay transmission duration. The preset SR delay transmission duration may be determined by obtaining a transmission parameter of the LC or LCG.

In one embodiment, the target SR delayed sending duration is set based on a preset SR delayed sending duration, for example, the target SR delayed sending duration is set to 1/2 of the preset SR delayed sending duration.

In one embodiment, the target LC and/or the target LCG are used to transmit data corresponding to a predetermined service, for example, to transmit data to be transmitted of a predetermined type. When the target LC and/or the target LCG are used to transmit data to be transmitted, if the SR triggering condition is met, the SR is sent based on the target SR delay transmission time, thereby reducing the delay of SR transmission and improving the efficiency of SR reporting and data transmission scheduling.

In some embodiments, the reporting rule further instructs the terminal:

Set the target BSR retransmission timing duration when the target LC and/or target LCG processes the scheduled service.

In the embodiment of the present disclosure, the BSR retransmission timing duration may indicate that the BSR is retransmitted after the BSR retransmission timing duration has passed since the second predetermined time. For example, the second predetermined time may be the time when the BSR was last sent or the time when the BSR sending is triggered. The scheduled service may be a specified service type such as an XR service. The scheduled service may also be a service corresponding to the predetermined type of data to be transmitted, for example, the predetermined type of data to be transmitted is generated by the scheduled service.

In one embodiment, setting the target BSR retransmission timing duration when the target LC and/or target LCG processes the scheduled service may include: setting a first BSR retransmission timing duration for the target LC and/or target LCG that processes the scheduled service; and setting a second BSR retransmission timing duration for the target LC and/or target LCG corresponding to non-scheduled services, such as service types other than XR services. At this time, the first BSR retransmission timing duration may be set to be less than the second BSR retransmission timing duration. In this way, the target LC and/or target LCG of the scheduled service can trigger BSR retransmission as soon as possible when BSR retransmission is required. Thus, a shorter delay time is waited for, and more timely reporting is achieved.

As an embodiment, a BSR retransmission timer (retxBSR-Timer) may be configured separately for the XR service.

In one embodiment, the method may further include: obtaining a preset BSR retransmission timing duration corresponding to at least one LC or LCG. At this time, the set target BSR retransmission timing duration is less than the preset BSR retransmission timing duration. The preset BSR retransmission timing duration may be determined by obtaining a transmission parameter of the LC or LCG.

In one embodiment, the target BSR retransmission timing duration is set based on a preset BSR retransmission timing duration, for example, the target BSR retransmission timing duration is set to 1/2 of the preset BSR retransmission timing duration.

In one embodiment, the target LC and/or the target LCG are used to transmit data corresponding to a predetermined service, for example, to transmit data to be transmitted of a predetermined type. When the target LC and/or the target LCG are used to transmit data to be transmitted, if the BSR triggering condition is met, the BSR is retransmitted based on the target BSR retransmission timing duration, thereby reducing the delay of BSR reporting and improving the efficiency of BSR reporting and data transmission scheduling.

As shown in FIG4 , an embodiment of the present disclosure provides an information transmission control method, which is executed by a terminal, and the method includes:

S310: Acquire a reporting rule based on at least one LCG among the multiple LCGs;

S320: Based on the reporting rule, report the BSR and/or SR through at least one LCG; the SR is associated with the BSR.

In the disclosed embodiment, BSR and SR are information sent by the terminal to the base station when it needs to request scheduling data, and are used to notify and instruct the base station to schedule data transmission. For example, when uplink transmission (UL) data of an LC belonging to an LCG is available, and the priority of the LC is higher than the priority of any LC containing available UL data belonging to any LCG, or other LCs belonging to the LCG do not contain any available UL data, the reporting of BSR is triggered.

In one embodiment, the SR associated with the BSR may be a scheduling request sent by the terminal to the base station when the BSR report fails or the transmission scheduling requested by the BSR fails after the BSR report is triggered. For example, when a BSR is triggered and there is no uplink shared channel (UL-SCH) resource available for new transmission; or the medium access control (MAC) entity configures an uplink grant of the configured grant type and the LogicalChannelSR-Mask parameter is false; or the UL-SCH resources available for new transmission do not meet the logical channel priority (LCP) mapping restrictions configured for the LC that triggers the BSR, the reporting of the scheduling request SR is triggered.

In the related technology, when BSR and/or SR are reported through multiple multiplexed LCGs, the SR delayed sending mechanism configured by other multiplexed LCGs often affects the target LCG that is not configured with the SR delayed sending mechanism, resulting in the target LCG that needs to send urgent data also having to go through the same SR delayed sending period before the SR report can be reported, resulting in the failure to send the urgent data in a timely manner.

In one embodiment, LCG can configure an SR delayed sending mechanism, which corresponds to an SR delayed sending timer (LogicalChannelSR-DelayTimer). The mechanism can instruct the terminal to report SR after the SR delayed sending time corresponding to the SR delayed sending timer after the SR report is triggered.

As shown in FIG5 , an embodiment of the present disclosure provides an information transmission control method, which is executed by a terminal, and the method includes:

S410: Acquire a reporting rule based on at least one LCG among the multiple LCGs;

S420: Based on the reporting rule, when at least one LCG among the multiple LCGs meets the BSR triggering condition, a BSR and/or SR is reported through a target LCG among the at least one LCG; and the SR is associated with the BSR.

In one embodiment, when multiple LCGs meet the BSR triggering conditions, BSR and/or SR are reported only through one target LCG or one target LC, that is, the BSR only carries a single target LC report, thereby reducing the impact of other multiplexed LCGs or LCs on the target LCG or target LC.

In some embodiments, reporting the BSR and/or SR by a target LCG in at least one LCG includes:

When there is at least one logical channel LC and/or LCG with the SR delayed sending function enabled in at least one LCG, the SR delayed sending function is stopped and the SR is reported.

In some embodiments, stopping the BSR and/or the SR includes:

In some embodiments, the method further comprises:

When there is a remaining delay budget of data corresponding to an LC in the target LCG that is lower than a predetermined threshold, it is determined that there is data to be transmitted of a predetermined type in the target LCG.

In some embodiments, the method further comprises:

The embodiment of the present disclosure provides a solution for controlling terminal reporting information. For example, the specific data reported may be data with high scheduling urgency requirements in a predetermined service such as XR. Specifically, it may include:

1. The network device notifies the terminal of the reporting rules of the LCG used in the BSR reporting process:

a) In one embodiment: the network instruction is reported by a single LC or a single LCG that triggers the BSR report (even if other LCGs also trigger the BSR sending);

b) In one embodiment: the network instructs LCG1 to be multiplexed only with LCG2, that is, if LCG1, LCG2 and LCG3 trigger BSR at the same time, then when reporting a long BSR, only the data of LCG1 and LCG2 are carried, and LCG3 is treated as having no data or does not need to be reported. For example, LCG1 and LCG2 may not be configured with a mechanism for delayed SR transmission. If they are multiplexed with LCG3 for reporting, and LCG3 is configured with a delayed transmission mechanism, it will cause a delay in the SR reporting of the BSR;

c) In one embodiment: the rule may be statically effective or dynamically effective;

d) In one embodiment: static validity means that the rule is valid once configured;

e) In one embodiment: dynamic effectiveness means that it takes effect when the terminal determines that there is a predetermined type of data (data requiring emergency scheduling) triggering the BSR; (that is, at this time only LCG1 and LCG2 are multiplexed; if there is no emergency scheduling data, it can be multiplexed with other LCGs);

f) In one embodiment: if the remaining data delay budget in the LC is less than a certain threshold (for example, the remaining delay budget of the data packet is determined to be less than 10 ms; the threshold can be obtained from a network notification), then the LCG to which the LC belongs has data that needs to be urgently scheduled.

2. The network configures a predetermined SR delay sending timer for the LC and/or LCG that needs to perform the scheduled service:

a) In one embodiment: the network instructs the LC and/or LCG that needs to perform the XR service to configure an SR delay sending timer specifically used for the XR service, such as XR-LogicalChannelSR-DelayTimer;

b) As an embodiment, the value configuration is smaller than LogicalChannelSR-DelayTimer.

3. The network configures the BSR to trigger an invalid SR delay sending timer or cancel the operation of the running SR delay sending timer for the LC and/or LCG that needs to perform the scheduled service:

a) In one embodiment: the rule may be statically effective or dynamically effective;

b) In one embodiment: statically effective, that is, the rule is effective if configured; for example, the LC and/or LCG performing the scheduled service triggers the BSR, and other LCs and/or LCGs that trigger the BSR report at the same time trigger the SR delay sending timer to start, then it is necessary to temporarily stop the timer, that is, trigger the SR report; (if there is no authorization to send the BSR at this time); the static configuration method can be implemented through dedicated signaling, such as RRC or MAC notification to the terminal.

c) In one embodiment: dynamic effectiveness, that is, when the terminal determines that there is a predetermined type of data (data that needs urgent scheduling) that triggers the BSR; for example, the LC triggers the BSR, and other LCs and/or LCGs that trigger the BSR report at the same time trigger the SR delay sending timer to start, then it is necessary to temporarily stop the timer, that is, trigger the SR report; (if there is no authorization to send the BSR at this time);

d) In one embodiment: the failed SR delay sending timer also means that even if the LC and/or LCG that needs to perform the scheduled service is configured with LogicalChannelSR-DelayTimerApplied, the SR delay sending timer will not be triggered to start.

For example, when the terminal determines that there is a predetermined type of data (data that needs to be urgently scheduled) that triggers the BSR, even if the SR delay sending timer is configured to be used, the SR delay sending timer will not be triggered to start. In this way, the SR can be triggered and reported in time.

4. In one embodiment, the network configures a specific retransmission timer for a logical channel/logical channel group that needs to perform a predetermined service:

a) In one embodiment: the network indicates that the LC and/or LCG that needs to perform XR services configures a retransmission timer specifically for XR services, such as XR-retxBSR-Timer.

b) In one embodiment, the value is configured to be smaller than retxBSR-Timer.
