Description

Method and device for scheduling request

Technical field

The embodiments of the present application relate to the field of communications, and in particular, to a method and a device for scheduling a request.

Background technique

Generally, the user equipment (UE) informs the network device of how much data needs to be sent in the uplink buffer through the Buffer Status Reporting (BSR), so that the network device determines how many uplink resources are allocated to the UE. When the terminal device triggers a regular BSR, the UE may also trigger a scheduling request (SR), and the network device may notify the network device that the data needs to be sent, and the network device may allocate an uplink resource that is at least enough to send the BSR. The UE sends the BSR to the network device by using the uplink resource.

Specifically, the UE first determines whether there is an available uplink resource, and then performs a subsequent determination decision whether the SR can be triggered. However, the existing standard (V15.1.0 of Release 15) does not involve how to determine whether there are uplink resources available for new transmission. This may cause the UE to make a mistake when deciding whether to trigger the SR, thereby affecting the uplink data transmission of the UE. , resulting in a large data delay.

Summary of the invention

The embodiment of the present application provides a method for triggering a scheduling request, a method for processing a logical channel priority, and a device. The UE can accurately determine whether to trigger an SR, and avoid data delay caused by the SR not being triggered in time.

To achieve the above objective, the embodiment of the present application adopts the following technical solutions:

In a first aspect, the embodiment of the present application provides a method for triggering a scheduling request, including: if a terminal device has at least one triggered buffer status report, the terminal device determines a first condition: there is a first uplink resource that can be used for new transmission. And the first uplink resource is configured by the network device, that is, the first uplink resource is not dynamically allocated by the network device. Further, if the first condition is met, the terminal device triggers a scheduling request, where the scheduling request is used to request the second uplink resource, and the second uplink resource is the uplink resource used for the new transmission.

In the triggering method of the scheduling request provided by the embodiment of the present invention, whether the UE determines whether the next uplink resource is available, or whether to increase the judgment condition (for example, whether there is an uplink resource that can be used for the newly transmitted configuration, that is, the period The emerging uplink resources) to accurately determine whether to trigger the SR. For example, the scenario that triggers the SR is added by the new judgment condition, and the SR that cannot be triggered because the UE cannot accurately determine the availability of the next uplink resource can be triggered, and the uplink resource can be requested in time to enable the data to be sent in time, thereby avoiding data. The delay is too large. In the method provided by the embodiment of the present invention, the UE determines that there is a network device configuration available for the new transmission, although the UE is ambiguous in delimiting the behavior of whether the uplink resource is available. The first uplink resource triggers the SR, which avoids the UE decision-making mistake to a certain extent. In addition, the UE can request the uplink resource from the network device by using the triggered SR, and further can transmit data according to the uplink resource dynamically allocated by the network device, and does not wait for the next configured uplink resource to resend the data, thereby greatly reducing the data delay.

In conjunction with the first aspect, in a first possible implementation manner of the first aspect, the first condition further includes at least one of the following conditions: a normal buffer status report with a trigger, and a logical channel scheduling request delay timer not running The status and regular cache status reports are not triggered by logical channels that are configured with logical channel scheduling requests disabled.

That is, in some implementations, the terminal device may also satisfy the determination of the above conditions (ie, a conventional buffer status report with a trigger, and the normal buffer status report is not triggered by a logical channel configured with a logical channel scheduling request disabled). After that, the SR is triggered. The triggered general cache status report can be understood as: the above-mentioned at least one triggered cache status report includes a regular cache status report. It should be noted that the triggered regular BSR is not triggered by the logical channel configured by the logical channel scheduling request. It can be understood that the triggered regular BSR is triggered by the logical channel that is not configured by the unconfigured logical channel scheduling request, or triggered.

The terminal device may consider that the next emerging uplink resource is available at intervals of the uplink resources that occur periodically, but may cause the data delay to be large if the next emerging uplink resource is considered to be available. In the embodiment of the present invention, the determining condition is: whether there is an uplink resource that can be used for the newly transmitted configuration (that is, an uplink resource that periodically appears), and if yes, the SR is triggered, and the UE may be triggered to some extent due to the UE behavior error.

detailed description

Referring to FIG. 1, the UE can generally use the SR to apply for transmission resources to the network device for transmitting new data, and the retransmission does not need to apply for resources through the SR. Specifically, the UE may transmit the SR to the network device by using an uplink resource. After the network is successfully decoded to the SR sent by the UE, the time-frequency resource block is allocated to the UE according to the SR, and the UE can use the time-frequency resource block allocated by the network device to transmit the uplink data.

In the fifth generation (5 Generation, 5G) New Radio (NR) system, the network device can dynamically allocate uplink transmission resources for the UE through Downlink Control Information (DCI), or semi-statically for the UE. The uplink transmission resource is configured, that is, the uplink transmission resource does not need to be dynamically allocated, but the uplink transmission resource is configured to the UE, and the UE considers that the configured uplink transmission resource is periodically generated, so that the control signaling in the resource allocation process can be reduced. Overhead. The non-dynamic (or semi-static) uplink transmission resource configured by the network device for the UE may be a configured grant type 1 or a configured grant type 2 (configured grant type 2).

The license type 1 and the configured license type 2 of the configuration related to the embodiment of the present invention are explained below:

(1) Configured license type 1:

The configured license type 1 can be regarded as a Grant Free resource, and the configured license type 1 can be considered as an uplink resource that periodically appears. The network device may configure the UE with a Radio Resource Control (RRC) message: the configured license type 1, the RRC message is also configured with the configured period of the license type 1 and the resource position of the configured license type 1. The configured license type 1 is generally an uplink resource with a short period and a high density, and is mainly used to transmit some services of Ultra Reliable & Low Latency Communication (URLLC).

(2) License type 2 configured:

The configured license type 2 can be regarded as an uplink semi-persistent Scheduling. It can be considered that the configured license type 2 is an uplink resource that periodically appears. The network device configures the UE by using an RRC message: the configured license type 2, and the RRC message is also configured with the configured period of the license type 2 and other related information. After the network device configures the configured grant type 2 for the UE, the UE cannot use the configured license type 2, and the network device also needs to activate the configured license type 2 by sending a DCI indication to the UE. The configured license type 2 can be used after the UE receives the DCI indicating the activation, and the DCI indicating the activation also indicates the resource location of the configured license type 2. The configured license type 2 is an uplink resource that does not require a short period, and is used to transmit services that occur periodically and have a fixed size, such as voice packets.

In the prior art, the UE first determines whether there are available uplink resources (such as dynamically scheduled uplink resources, uplink resources corresponding to the configured license type 1 or uplink resources corresponding to the configured license type 2), and then performs subsequent judgments. , to determine if the SR can be triggered. The specific process of the UE judgment refers to FIG. 2, specifically:

Step S1: If it is determined that there is at least one triggered BSR and the triggered BSR is not cancelled, it is further determined whether there is an uplink resource available for the new transmission. It should be noted that the uplink resource that can be used for new transmission refers to the uplink resource used for transmitting the initial transmission data, and the initial transmission data refers to the data that is transmitted for the first time.

If there are uplink resources available for new transmission, steps S2 and S3 are performed; if there are no uplink resources available for new transmission, step S4 is performed.

Step S2: The UE may generate a BSR Media Access Control (MAC) Control Element (CE), where the BSR MAC CE is used to carry the current cache state information of the UE. The buffer status information may indicate the amount of data to be sent to the network device in the uplink buffer of the UE. It should be noted that, in addition to the BSR MAC CE, the UE may perform other related operations, such as starting or restarting related timers, which are not described herein.

Step S3: determining whether the condition (1) is satisfied: the uplink resource that can be used for the new transmission does not satisfy the mapping constraint condition; the mapping constraint condition is a mapping constraint condition for processing the logical channel priority processing of the logical channel that triggers the BSR. It should be noted that the logical channel that triggers the BSR can be understood as: the logical channel has data to be transmitted and the BSR is triggered, or the logical channel has a triggered BSR, or a BSR triggered by the logical channel.

If the uplink resource that can be used for the new transmission does not satisfy the mapping constraint of the logical channel priority processing corresponding to the logical channel that triggers the BSR, step S4 is performed. If condition (1) is not met, the SR is not triggered.

Step S4: It is judged whether the condition (2) is satisfied: a regular BSR (Regular BSR) is triggered, and the logical channel scheduling request delay timer (logicalChannelSR-DelayTimer) is not in the running state.

If condition (2) is satisfied, step S5 is performed. If condition (2) is not met, the SR is not triggered.

Step S5: further determining whether the condition (3) is satisfied: the uplink resource that is available for the new transmission is not the configured permission; or the triggered regular BSR is not triggered by the logical channel configured with the logical channel scheduling request prohibition (logicalChannelSR-Mask) . It should be noted that the uplink resource that can be used for the new transmission is not the configured license, and the uplink resource that can be used for the new transmission can be considered as the configured license type 1, or the configured license type 2, or the configured license type 1 and configuration. License Type 2; alternatively, it can be considered that "Configured License Type 1" is not configured, or "Configured License Type 2" is not configured, or "Configured License Type 1" and "Configured License Type 2" are not configured. In addition, it should be noted that the triggered regular BSR is not triggered by the logical channel configured by the logical channel scheduling request. It can be understood that the triggered regular BSR is triggered by a logical channel that is not configured by the unconfigured logical channel scheduling request, or The logical channel triggering the regular BSR is not a logical channel configured with the logical channel scheduling request barring, or the logical channel triggering the regular BSR is not configured to be disabled by the configured logical channel scheduling request.

If the above condition (3) is satisfied, the SR is triggered. If condition (3) is not met, the SR is not triggered.

It should be noted that the triggering of the SR is triggered by the SR, and the MAC entity of the current UE or the UE may be considered to have the triggered SR, or the MAC entity of the current UE or the UE is in the SR triggered state. When there is a triggered SR, the UE needs to further determine the transmission condition of the SR, and the UE can send the SR when the condition of the SR is satisfied. In addition, the UE needs to further determine the cancellation condition of the SR. When the cancellation condition of the SR is satisfied, the triggered SR is cancelled.

However, the prior art does not involve determining whether there is an uplink resource that can be used for new transmission. This may cause the UE to make a mistake when deciding whether to trigger the SR, thereby affecting the uplink data transmission of the UE, resulting in a large data delay. .

For example, the UE prematurely considers that an uplink resource is available, that is, an uplink resource that is still a long time from the current time is considered to be available. Further, the UE enters the steps in the judgment flow shown in FIG. 2, and it is possible to finally decide not to trigger the SR. For example, referring to FIG. 3, the current time is T, the uplink resource that appears before the time T is the uplink resource 1, and the uplink resource that appears after the time T is the uplink resource 2.

The UE determines at time T that the uplink resource 2 is an uplink resource available for new transmission. Further, the UE performs step S2 and step S3. Further, the uplink resource that can be used for the new transmission may meet the mapping constraint of the logical channel priority processing corresponding to the logical channel that triggers the regular BSR, that is, the above condition (1) is not satisfied, even if a regular BSR is triggered and the logical channel scheduling request is met. Delaying the timer, and satisfying that: the above-mentioned condition that the uplink resource that can be used for the new transmission is not configured or triggered is not triggered by the logical channel configured by the logical channel scheduling request, that is, the condition (2) and the condition satisfying the above condition are met. 3) At this time, the UE will not trigger the SR. Since the uplink resource 2 has a long time from the time T, it means that the BSR triggered by the logical channel cannot trigger the SR during this long time, that is, the dynamically scheduled resource cannot be requested more quickly. At this time, the data of the logical channel can be sent only after the long-term resource 2 resources are waited for a long time, which will result in a large delay of the data of the logical channel.

That is to say, the UE cannot trigger the SR for a long time before the uplink resource occurs, and the dynamically scheduled resource cannot be requested. At this time, the UE can only wait for a long time to send data on the uplink resource, which will result in a large delay of the data.

In the triggering method of the scheduling request provided by the embodiment of the present invention, when the terminal device has at least one triggered buffer status report, the terminal device determines that the first condition is met: there is a first uplink resource that can be used for new transmission, and the first uplink resource is And configured by the network device, the terminal device triggers a scheduling request, where the scheduling request is used to request a second uplink resource. The second uplink resource is an uplink resource used for new transmission. In the prior art, for a scenario in which an uplink resource periodically occurs, whether the UE defines whether the uplink resource is available or not is not explicitly specified, and the behavior of the UE (eg, prematurely considering that the next uplink resource is available) may cause the UE to trigger in the decision. When the SR is faulty (for example, the SR cannot be triggered, the uplink resource cannot be requested early), resulting in excessive data latency. However, in the embodiment of the present invention, regardless of when the UE determines whether the next uplink resource is available, whether the uplink condition is available, for example, whether there is an uplink resource that can be used for the newly transmitted configuration, that is, an uplink resource that periodically appears. To make an accurate decision whether to trigger the SR. For example, the scenario that triggers the SR is added by the new judgment condition, and the SR that cannot be triggered because the UE cannot accurately determine the availability of the next uplink resource can be triggered, and the uplink resource can be requested in time to enable the data to be sent in time, thereby avoiding data. The delay is too large. In the method provided by the embodiment of the present invention, the UE determines that there is a network device configuration available for the new transmission, although the UE is ambiguous in delimiting the behavior of whether the uplink resource is available. The first uplink resource triggers the SR, which avoids the UE decision-making mistake to a certain extent. In addition, the UE can request the uplink resource from the network device by using the triggered SR, and further can transmit data according to the uplink resource dynamically allocated by the network device, and does not wait for the next configured uplink resource to resend the data, thereby greatly reducing the data delay.

The method for triggering the scheduling request provided by the embodiment of the present invention is applicable to the terminal device shown in FIG. As shown in FIG. 4, the terminal device may include at least one processor 401, a memory 402, a transceiver 403, and a communication bus 404.

The terminal device structure shown in FIG. 4 does not constitute a limitation of the terminal device, and may include more or less components than those illustrated, or a combination of certain components, or different component arrangements.

An embodiment of the present invention provides a method for triggering a scheduling request. As shown in FIG. 5, the method includes the following steps:

501. When the terminal device has at least one triggered buffer status report, the terminal device determines a first condition: there is a first uplink resource that is available for new transmission, and the first uplink resource is configured by the network device.

The first uplink resource may be an uplink transmission resource configured by the network device for the UE, and the first uplink resource may be an uplink resource that periodically appears, for example, an uplink resource corresponding to the configured license type 1, or a configured license type 2 Corresponding uplink resources. In some embodiments, the first uplink resource may be an uplink resource corresponding to the configured license type 2. In some embodiments, the first uplink resource may also be at least one of an uplink resource corresponding to the configured license type 1 and an uplink resource corresponding to the configured license type 2.

It should be noted that when the UE (that is, the terminal device in the embodiment of the present invention) or the MAC entity of the UE determines that there is at least one triggered BSR (that is, the cache status report in the embodiment of the present invention) and the triggered BSR If it is not canceled, it is further judged whether the first condition is satisfied. In the embodiment of the present invention, when there is data to be sent in the uplink buffer of the UE, the BSR may be triggered according to the trigger condition of the BSR, and the BSR notifies the network device UE of how much data needs to be sent in the uplink buffer.

In addition, before the step 501, the network device configures the information of the first uplink resource, such as the period of the first uplink resource, for the UE by using the RRC message.

In some embodiments, the network device configures the configured grant type 1 for the UE, that is, the first uplink resource is the uplink resource corresponding to the configured license type 1, and the information of the first uplink resource configured by the network device for the UE by using the RRC message includes: After the RRC message sent by the network device is received, the UE may determine the time frequency of the first uplink resource according to the period indicated by the RRC message and the resource location. a location, and the UE may determine the next uplink resource that is present at the current time, and the first uplink resource that is the next one is the first uplink resource that is used for the new transmission, that is, the first uplink resource that the UE can consider as the next one. It's useful. The current time can understand the time when the terminal device determines whether the first condition is met. When the UE determines that the next uplink resource that is present is available, it is determined that the first condition is met, and then step 502 is performed.

In some embodiments, the resource configured by the network device for the UE is the configured grant type 2, that is, the first uplink resource is the uplink resource corresponding to the configured license type 2, and the first uplink resource configured by the network device for the UE by using the RRC message. The information includes the period of the license type 2 of the configuration, and the UE may not use the first uplink resource indicated by the RRC message after receiving the RRC message sent by the network device. After the UE receives the DCI of the permission type 2 that is activated by the network device, the UE may determine the time frequency of the first uplink resource according to the configured resource type of the permission type 2 indicated by the DCI and the period indicated by the RRC message. a location, and the UE may determine the next uplink resource that is present at the current time, and the first uplink resource that is the next one is the first uplink resource that is used for the new transmission, that is, the first uplink resource that the UE can consider as the next one. It's useful. When the UE determines that the next uplink resource that is present is available, it is determined that the first condition is met, and then step 502 is performed.

502. The terminal device triggers a scheduling request, where the scheduling request is used to request a second uplink resource, and the second uplink resource is an uplink resource used for a new transmission.

It should be noted that the second uplink resource is different from the first uplink resource, and the second uplink resource may appear earlier in the time domain than the first uplink resource. The UE can send the newly transmitted data to the network device by using the second uplink resource, and the data delay is reduced to some extent without waiting for the first uplink resource to appear and then sending the data.

In some embodiments, the first condition further includes at least one of the following conditions: a triggered general buffer status report, a logical channel scheduling request delay timer not in an active state, and the conventional cache status report is not configured by logic The channel scheduling request is prohibited by the logical channel triggered.

The above-mentioned "conventional cache status report" in the embodiment of the present invention may be a regular cache status report in step 501 "at least one triggered cache status report". A regular cache status report with a trigger can be understood as a regular cache status report with a trigger, or a regular cache status report with at least one trigger. The cache status report may include a regular cache status report Regular BSR, a padding buffer status report Padding BSR, and a periodic buffer status report Periodic BSR. When any logical channel belonging to a logical channel group has no transmittable data, a logical channel belonging to the logical channel group has data arriving, and a regular BSR is triggered; or, there is a higher priority belonging to the logical channel group. The logical channel has data arrival, it will trigger the regular BSR; or, the BSR triggered by the buffer status report retransmission timer retxBSR-Timer timeout is a regular BSR.

The scheduling request delay timer is a timer set for one MAC entity of one UE. During the scheduling request delay timer operation, the UE cannot trigger the SR. When the scheduling request delay timer is not in the running state, the UE is possible. Trigger SR.

In addition, when the logical channel is configured with the logical channel prohibiting scheduling request, the logical channel cannot trigger the SR, and only the logical channel is not configured with the logical channel to prohibit the scheduling request, and the logical channel may trigger the SR. Generally, when the UE has a voice service on a certain logical channel, the network device can configure the UE: the configured license type 2, because the network device knows the service period and size on the logical channel of the voice service of the UE, for the voice The data on the logical channel of the service does not need to request resources through the SR. Therefore, the network device can disable the scheduling request by configuring a logical channel for the logical channel of the voice service, so that the logical channel of the voice service does not trigger the SR, but other The logical channel can still allow the SR to be triggered normally. It should be noted that the logical channel triggers the SR, which can be understood as: the logical channel has a triggered BSR, but the BSR cannot trigger the SR further.

In some embodiments, after the terminal device triggers the scheduling request, the terminal device may further receive an indication message sent by the network device, where the indication message is used to indicate the second uplink resource, before the first uplink resource. . That is, after receiving the SR sent by the terminal device, the network device can learn the data transmission requirement of the terminal device, and then dynamically allocate the uplink resource through the DCI, so that the terminal device sends the data through the uplink resource dynamically allocated by the network device.

In some embodiments, that is, when there is at least one triggered BSR and the triggered BSR is not cancelled, the UE may decide whether to trigger the SR by the following conditions:

Condition 1: If there is an uplink resource available for new transmission, a BSR MAC CE is generated;

Condition 2: Condition 2a, if there is no upstream resource available for new transmission; or,

Condition 2b, if the uplink resource available for the new transmission does not satisfy the mapping constraint of the logical channel priority processing corresponding to one or more logical channels that trigger the BSR; or

Condition 2c, if the uplink resource that can be used for the new transmission is the uplink resource corresponding to the configured license type 2;

Condition 3: If there is a regular buffer status report (Regular BSR) triggered and the logical channel scheduling request delay timer (logicalChannelSR-DelayTimer) is not running;

Condition 4: Condition 4a, if the uplink resource is not a configured license, or the configured license is not configured; or,

Condition 4b, the regular BSR is not triggered by a logical channel configured with a logical channel scheduling request prohibition (logicalChannelSR-Mask).

In a specific implementation, when there is at least one triggered BSR, and the triggered BSR is not cancelled, if the UE determines that there is an uplink resource available for new transmission, that is, the condition 1 is satisfied, the UE generates a BSR MAC CE, Condition 1 and Condition 2 -4 is relatively independent, and the UE must further judge the condition 2-4 regardless of the judgment result of the condition 1. If neither condition 2a, condition 2b, and condition 2c is satisfied, SR is not triggered; if any of condition 2a, condition 2b, and condition 2c is satisfied, it is further determined whether condition 3 is satisfied. If condition 3 is not satisfied, SR is not triggered; if condition 3 is satisfied, it is further determined whether condition 4a or condition 4b is satisfied. If neither condition 4a nor condition 4b is satisfied, SR is not triggered; if either of condition 4a and condition 4b is satisfied, SR is triggered.

The following is a description of the method provided by the embodiment of the present invention. Referring to FIG. 6, the current time is T, the uplink resource that appears before time T is uplink resource 1, and the uplink resource that appears after time T is uplink resource 2.

Referring to mode (a) in Fig. 6, the manner in which the prior art triggers the SR. The UE determines at time T that the uplink resource 2 is an uplink resource available for new transmission. Further, the UE performs step S2 and step S3. Further, the uplink resource that can be used for the new transmission may meet the mapping constraint of the logical channel priority processing corresponding to the logical channel that triggers the regular BSR, that is, the above condition (1) is not satisfied, even if a regular BSR is triggered and the logical channel scheduling request is met. Delaying the timer, and satisfying that: the above-mentioned condition that the uplink resource that can be used for the new transmission is not configured or triggered is not triggered by the logical channel configured by the logical channel scheduling request, that is, the condition (2) and the condition satisfying the above condition are met. 3) At this time, the UE will not trigger the SR. Since the uplink resource 2 has a long time from the time T, it means that the BSR triggered by the logical channel cannot trigger the SR during this long time, that is, the dynamically scheduled resource cannot be requested more quickly. At this time, the data of the logical channel can only be sent out after the uplink resource 2 resources are waiting for a long time, which will result in a large delay of the data of the logical channel.

Referring to mode (b) in FIG. 6, in the embodiment of the present invention, the UE determines that the uplink resource 2 is an uplink resource that can be used for new transmission at time T (ie, does not satisfy condition 2a). Further, the UE determines that the conventional BSR is currently triggered, and the uplink resource corresponding to the configured permission type 2 satisfies the mapping constraint of the logical channel priority processing corresponding to the logical channel that triggers the regular BSR (ie, the condition 2b is not satisfied). It is further determined that the resource configured by the network device for the UE is the configured license type 2 (ie, the condition 2c above is satisfied). Since the condition 2c in the condition 2a, the condition 2b, and the condition 2c is satisfied, the UE can further judge whether or not the condition 3 is satisfied. If condition 3, condition 4b (or condition 4a) is also satisfied, the SR can be triggered. It should be noted that the condition 2c can be considered as satisfying the first condition described in the embodiment of the present invention: there is a first uplink resource that can be used for new transmission, and the first uplink resource is configured by the network device. In addition, the SR is configured to request, from the network device, a second uplink resource that is available for new transmission, such as the uplink resource 3 shown in FIG. 6. The uplink resource 3 may appear earlier than the uplink resource 2 in the time domain. Therefore, the data of the logical channel can be sent on the uplink resource 3, and the uplink resource 2 resource is not sent after a long time, which greatly reduces the data delay.

It should be noted that, in some embodiments, the condition 2b may also be: if the uplink resource available for the new transmission does not satisfy the mapping constraint of the logical channel priority processing corresponding to the one or more logical channels that trigger the BSR, and The uplink resource that can be used for the new transmission is not the uplink resource corresponding to the configured license type 2.

In other embodiments, that is, when there is at least one triggered BSR and the triggered BSR is not cancelled, the UE may decide whether to trigger the SR by the following conditions:

Condition S1: if there is an uplink resource available for new transmission, a BSR MAC CE is generated;

Condition S2: condition S2a, if there is no uplink resource available for new transmission; or,

Condition S2b, if the uplink resource available for the new transmission does not satisfy the mapping constraint of the logical channel priority processing corresponding to one or more logical channels that trigger the BSR; or

Condition S2c, if the uplink resource available for the new transmission is the uplink resource corresponding to the configured grant type 2, and the regular BSR is not triggered by the logical channel configured with the logical channel scheduling request prohibition (logicalChannelSR-Mask);

Condition S3: If a regular Buffer Status Report (Regular BSR) is triggered and the logical channel scheduling request delay timer (logicalChannelSR-DelayTimer) is not in the running state.

In a specific implementation, when there is at least one triggered BSR, and the triggered BSR is not cancelled, if the UE determines that there is an uplink resource available for new transmission, that is, the condition S1 is satisfied, the UE generates a BSR MAC CE, condition S1 and condition S2- S3 is relatively independent, and the UE further judges the condition S2-S3 regardless of the judgment result of the condition S1. If neither condition S2a, condition S2b, and condition S2c is satisfied, SR is not triggered; if any of condition S2a, condition S2b, and condition S2c is satisfied, it is further determined whether condition S3 is satisfied. If condition S3 is not satisfied, SR is not triggered; if condition S3 is satisfied, SR is triggered.

Similarly, in the manner (b) shown in FIG. 6, the UE determines that the uplink resource 2 is an uplink resource available for new transmission at time T (ie, the condition S2a is not satisfied). Further, the UE determines that the conventional BSR is currently triggered, and the configured uplink resource corresponding to the permission type 2 meets the mapping constraint of the logical channel priority processing corresponding to the logical channel that triggers the regular BSR (ie, the condition S2b is not satisfied). It is further determined that the resource configured by the network device for the UE is the configured license type 2 (ie, the above condition S2c is satisfied). Since the condition S2c in the condition S2a, the condition S2b, and the condition S2c is satisfied, the UE can further determine whether the condition S3 is satisfied. If condition S3 is also met, the SR can be triggered. It should be noted that the condition S2c can be considered as satisfying the first condition described in the embodiment of the present invention: there is a first uplink resource that can be used for new transmission, and the first uplink resource is configured by the network device. In addition, the SR is configured to request, from the network device, a second uplink resource that is available for new transmission, such as the uplink resource 3 shown in FIG. 6. The uplink resource 3 may appear earlier than the uplink resource 2 in the time domain. Therefore, the data of the logical channel can be sent on the uplink resource 3, and the uplink resource 2 resource is not sent after a long time, which greatly reduces the data delay.

It should be noted that, in other embodiments, the condition S2b may be: if the uplink resource that can be used for the new transmission does not meet the mapping constraint of the logical channel priority processing corresponding to the one or more logical channels that trigger the BSR, And the uplink resource that can be used for the new transmission is not the uplink resource corresponding to the configured license type 2.

In other embodiments, the condition S2c may also be: if the uplink resource available for the new transmission is the uplink resource corresponding to the configured grant type 2 and the uplink resource available for the new transmission meets one or more logical channels that trigger the BSR. Corresponding logical channel priority processing mapping constraints, and the regular BSR is not triggered by a logical channel configured with logical channel scheduling request barring (logicalChannelSR-Mask).

It should be noted that, in the triggering SR process in the embodiment of the present invention, the sequence of the determining conditions is only used as an example. In the embodiment of the present invention, the sequence of the determining conditions in each triggering process is not limited. For example, the determination order of the condition 1, the condition 2, the condition 3, and the condition 4 is not limited, and the determination order of the condition S1, the condition S2, and the condition S3 is not limited, and the determination order of the condition 2a, the condition 2b, and the condition 2c is not limited, and is not limited. The order of judgment of the condition S2a, the condition S2b, and the condition S2c. It will be apparent to those skilled in the art that combinations of various sequences of conditions are within the scope of the invention.

It should be noted that the mapping constraints described in the embodiments of the present invention are explained as follows: One UE may be configured with multiple radio bearers, that is, corresponding to multiple logical channels. When the UE receives the uplink resource allocated by the network device, the UE needs to determine, by using logical channel priority processing, which logical channel data can be put into the uplink resource and how much data can be put into each logical channel.

Specifically, in the 5G NR, the network device may configure a mapping constraint for logical channel priority processing for each logical channel of the UE, and the UE needs to configure a logical channel according to each logical channel for each received uplink resource. The mapping constraint of the priority processing is used to select a logical channel that can be transmitted on the uplink resource, and specifically includes: the subcarrier spacing allowed by the data of the logical channel (the subcarrier spacing index included in the allowed SCS-List) includes the The maximum number of physical uplink shared channel (PUSCH) durations (maxPUSCH-Duration) allowed by the logical channel is greater than or equal to the physical uplink shared channel duration corresponding to the uplink resource, and the logical channel is configured. Whether the data is allowed to use the configured license type 1 (configuredGrantType1Allowed), the reserved channel (allowedServingCells) of the logical channel contains the cell information corresponding to the uplink resource. For example, the mapping constraint of the logical channel priority processing corresponding to a certain logical channel of the UE includes: the configured permission type 1 is not allowed, and the data on the logical channel of the UE may not pass the uplink corresponding to the configured license type 1. Resources occur.

The prior art does not clearly define how to determine that the uplink resource is available, which may cause the UE to make a mistake when implementing the decision triggering SR. Different UEs may have different behaviors. For example, the UE considers that an uplink resource with 1 ms from the current time is available, or whether uplink resources with 10 ms from the current time are available.

The embodiment of the present invention further provides a triggering method for scheduling a request. The terminal device can accurately determine whether there is an uplink resource that can be used for new transmission according to the time parameter, and then perform subsequent judgment, and finally decide whether to trigger the SR according to the judgment result. The behavior of the terminal device is regulated by a time parameter to prevent the data delay from being too large due to the terminal device prematurely considering that the next uplink resource is available.

As shown in FIG. 7, the method for triggering a scheduling request according to an embodiment of the present invention includes the following steps:

701. If the terminal device has at least one triggered buffer status report, the terminal device determines a first condition according to the time parameter, where the first condition includes: there is no first uplink resource that can be used for new transmission, or the A condition includes: there is a first uplink resource available for new transmission, and the first uplink resource does not satisfy the logical channel priority processing mapping constraint that the logical channel that triggered the buffer status report is configured.

In a specific implementation, the terminal device may determine a time window according to the time parameter, where the starting point of the time window is the current time, and the length of the time window is the first time length indicated by the time parameter. The current moment may be a moment when the terminal device determines the first condition.

If the terminal device has the first uplink resource that can be used for the new transmission in the foregoing time window, the determined first condition includes: the first uplink resource that is available for the new transmission, and further, the terminal device may perform the priority according to the logical channel. The level processing mapping constraint determines that the first uplink resource does not satisfy the logical channel priority processing mapping constraint that the logical channel that triggered the buffer status report is configured. The logical channel priority processing mapping constraint is the above logical channel priority processing mapping constraint.

It should be noted that, referring to FIG. 8, when the start time of the time window is earlier than the start time of the first uplink resource, and the time window overlaps with the time domain position of the first uplink resource, it is determined that there is a new transmission available. The first uplink resource. Specifically, as shown in mode (a) of FIG. 8, the time window may include a time domain location of the first uplink resource; as in the mode (b) in FIG. 8, the time window may also include a time domain location of the first uplink resource. In some embodiments, the embodiment of the present invention does not limit this.

If the terminal device does not have the first uplink resource available for the new transmission in the time window, the determined first condition includes: there is no first uplink resource available for the new transmission.

It should be noted that, referring to FIG. 9, when the start time of the time window is earlier than the start time of the first uplink resource, and the time window does not overlap with the time domain position of the first uplink resource, it is determined that there is no available. The first uplink resource of the new pass.

In some embodiments, the terminal device may also use the time when the first uplink resource appears as a reference point, and determine, in combination with the first duration, which moments before the first uplink resource occurs, and which moments the first uplink resource is considered to be available, and which At the moment, the first uplink resource may be considered as unavailable. Specifically, the terminal device may determine that the first uplink resource is available for new transmission within a first time period before the first uplink resource occurs. For example, referring to FIG. 10, the time when the next first uplink resource (the uplink resource 2 in FIG. 10) appears is T1, the time T2 is separated from the time T1 by the first time, and the terminal device is at the time T3 earlier than the time T2. It is determined that an uplink transmission resource is about to occur. Since the interval between the T3 time and the T1 time is greater than the first time length, the terminal device considers that the next first uplink resource is unavailable; the terminal device determines that the terminal device is about to appear at time T4 later than the T2 time. An uplink transmission resource, because the interval between the time T4 and the time T1 is less than the first time length, the terminal device considers that the next uplink resource that appears next is available. It should be noted that the end time of the first duration may be the start time of the corresponding first uplink resource (the uplink resource 2 in FIG. 10), and the end time of the first duration may also exist with the time domain location of the first uplink resource. The embodiment of the present invention does not limit this.

702. If the first condition is met, the terminal device triggers a scheduling request, where the scheduling request is used to request a second uplink resource, and the second uplink resource is an uplink resource used for new transmission. The time parameter is a time parameter corresponding to the configured license type 2; or the time parameter is a time parameter corresponding to at least one of the configured license type 1 and the configured license type 2.

In some embodiments, the first condition further includes at least one of the following conditions: a conventional cache status report exists in the cache status report, a logical channel scheduling request delay timer is not in an active state, and the regular cache status report is not Triggered by a logical channel configured with a logical channel scheduling request disabled.

In some embodiments, if the terminal device has at least one triggered buffer status report and there is a first uplink resource available for new transmission, the terminal device generates a BSR MAC CE.

In the embodiment of the present invention, when there is at least one triggered BSR, and the triggered BSR is not cancelled, the UE may decide whether to trigger the SR according to the time parameter by using the following conditions:

Condition 1R: if there is an uplink resource available for new transmission, a BSR MAC CE is generated;

Condition 2R: condition 2Ra, if there is no uplink resource available for new transmission; or,

Condition 2Rb, if the uplink resource available for new transmission does not satisfy the mapping constraint for logical channel priority processing corresponding to one or more logical channels that trigger the BSR;

Condition 3R: If there is a regular Buffer Status Report (Regular BSR) triggered and the logical channel scheduling request delay timer logicalChannelSR-DelayTimer is not running;

Condition 4R: condition 4Ra, if the uplink resource is not a configured license, or the configured license is not configured; or,

Condition 4Rb, the regular BSR is not triggered by a logical channel configured with a logical channel scheduling request prohibition (logicalChannelSR-Mask).

In a specific implementation, when there is at least one triggered BSR, and the triggered BSR is not cancelled, if the UE determines that there is an uplink resource available for new transmission according to the time parameter, that is, the condition 1R is satisfied, the condition 1R and the condition 2R-4R are relatively independent. The UE shall further judge the condition 2R-4R regardless of the judgment result of the condition 1R. If the UE determines that the condition R2a and the condition R2b are not satisfied according to the time parameter, the SR is not triggered; if the UE determines that any of the condition R2a and the condition R2b is satisfied according to the time parameter, it is further determined whether the condition 3R is satisfied. If the condition 3R is not satisfied, the SR is not triggered; if the condition 3R is satisfied, it is further determined whether the condition R4a or the condition R4b is satisfied. If neither condition R4a nor condition R4b is satisfied, SR is not triggered; if any of condition R4a, R condition 4b is satisfied, SR is triggered.

In a specific implementation, the time parameter may be dynamically indicated by the network device to the terminal device. Specifically, the terminal device receives a configuration message sent by the network device, where the configuration message is used to indicate the time parameter. The terminal device can determine the time parameter after receiving the configuration message sent by the network device.

The configuration message is a broadcast message, or the configuration message is a radio link control dedicated message, or the configuration message is downlink control information.

For example, the length of the first time length t can be indicated by a configuration message.

In some embodiments, the time parameter may also be pre-configured, in particular: the time parameter is pre-stored in the terminal device. The time parameter is used to indicate a duration, and the duration is the first duration. In other words, the first duration is the only constant.

Certainly, the time parameter may also indicate at least two durations and one of the at least two durations corresponds to one of the at least one uplink resource subcarrier interval. A first duration may be selected as the duration of the time parameter indication in the at least the duration.

For example, as shown in Table 1, the correspondence between the uplink (UL-SCH) resource subcarrier spacing and the duration may be specified in the standard in advance. When performing step 701, the UE may determine a corresponding first duration according to a subcarrier spacing of the UL-SCH resource.

Table 1

UL-SCH资源的子载波间隔Subcarrier spacing of UL-SCH resources	第一时长tFirst time t
15kHZ15kHZ	aa
30kHZ30kHZ	bb
60kHZ60kHZ	cc
…...	…...

In some embodiments, if the time parameter is a time parameter corresponding to the configured permission type 2, the network device may indicate the time parameter by indicating downlink control information (DCI) of the permission type 2 of the activated configuration. For example, the DCI carries a time parameter indication field, and the value of the indication field indicates the length of the first duration; or the network device may also multiplex the K2 value indicating the DCI indication of the permission type 2 that activates the configuration. Indicates the time parameter. When the network device sends the DCI of the permission type 2 indicating the activation configuration, the resource location of the configured permission type 2 is required, where the value of the indication K2 is included, and the value of the K2 is used to indicate that the terminal device receives the downlink. The length of time between the time when the control information arrives and the time when the uplink transmission resource corresponding to the configured license type 2 appears. The terminal device can directly consider the value of K2 as the length of the first duration, so that there is no need to additionally have a time parameter indication domain, thereby saving signaling overhead.

The following is a description of the method provided by the embodiment of the present invention. Referring to FIG. 11, the current time is T, the uplink resource that appears before time T is uplink resource 1, and the uplink resource that appears after time T is uplink resource 2.

Referring to mode (a) in FIG. 11, in the prior art, the UE determines that the uplink resource 2 is an uplink resource available for new transmission at time T. Further, the UE performs step S2 and step S3. Further, the uplink resource that can be used for the new transmission may meet the mapping constraint of the logical channel priority processing corresponding to the logical channel that triggers the regular BSR, that is, the above condition (1) is not satisfied, even if a regular BSR is triggered and the logical channel scheduling request is met. Delaying the timer, and satisfying that: the above-mentioned condition that the uplink resource that can be used for the new transmission is not configured or triggered is not triggered by the logical channel configured by the logical channel scheduling request, that is, the condition (2) and the condition satisfying the above condition are met. 3) At this time, the UE will not trigger the SR. Since the uplink resource 2 has a long time from the time T, it means that the BSR triggered by the logical channel cannot trigger the SR during this long time, that is, the dynamically scheduled resource cannot be requested more quickly. At this time, the data of the logical channel can be sent only after the long-term resource 2 resources are waited for a long time, which will result in a large delay of the data of the logical channel.

Referring to mode (b) in FIG. 11, in the embodiment of the present invention, the first duration indicated by the time parameter is t, which is smaller than the interval between the current time and the uplink resource 2, and it can be seen that the uplink resource 2 is not in the time window (the starting time is In T, the length is t), and the UE determines that the uplink resource 2 is not available for the newly transmitted uplink resource at the time T, that is, the condition R2a is satisfied. Further, if the UE determines that the condition 3R and the condition 4Rb (or the condition 4Ra) are also satisfied, the SR may be triggered. That is, the UE may trigger the SR at the current time T. Further, after receiving the SR sent by the UE, the network device may indicate the dynamically allocated uplink resource to the UE through the DCI, such as the uplink resource 3 shown in FIG. The uplink resource 3 may appear earlier than the uplink resource 2 in the time domain. Therefore, the data of the logical channel can be sent on the uplink resource 3, and the uplink resource 2 resource is not sent after a long time, which greatly reduces the data delay.

In the embodiment of the present invention, the time parameter may be dynamically indicated by the network device to the terminal device. Based on this, the embodiment of the present invention provides a method for triggering a scheduling request. As shown in FIG. 12, the method includes the following steps:

1201: The network device generates a configuration message, where the configuration message is used to indicate a time parameter; the time parameter is a time parameter corresponding to the configured license type 2; or the time parameter is a configured license type 1 and a configured license type. At least one of the corresponding time parameters of 2.

The configuration message may be a broadcast message of the network device, a radio link control dedicated message, or a downlink control information.

1202. The network device sends a configuration message to the terminal device.

In a specific implementation, after receiving the configuration message sent by the network device, the terminal device may further determine, according to the time parameter, whether to trigger the scheduling request. If the terminal determines the first condition according to the time parameter (the first condition described in step 701 of the embodiment of the present invention), the scheduling request may be triggered. Further, if the triggered scheduling request satisfies the sending condition, the terminal device may send a scheduling request to the network device. After receiving the scheduling request sent by the terminal device, the network device may dynamically allocate the uplink resource to the terminal device by using the downlink control signaling, such as the second uplink resource in the embodiment of the present invention, where the second uplink resource is used for the newly transmitted uplink. Resources.

In some embodiments, if the time parameter is a time parameter corresponding to the configured permission type 2, and the downlink control information is downlink control information of the permission type 2 that activates the configuration.

Further, the downlink control information (refers to the downlink control information of the permission type 2 that activates the configuration) includes a time parameter indication field, and the value of the time parameter indication field is the first duration.

Or the value of K2 indicated by the downlink control information of the permission type 2 of the configuration is the first time length. Of course, the value of K2 is further used to indicate that the terminal device receives the downlink control information. The length of time between when the uplink transmission resources corresponding to the configured license type 2 appear.

The embodiment of the present invention further provides a logical channel priority processing method, which adds a new logical channel priority processing mapping constraint parameter to standardize the behavior of the terminal device. As shown in FIG. 18, the logical channel priority provided by the embodiment of the present invention is provided. The level processing method includes the following steps:

1801: The network device generates a first message, where the first message indicates a mapping constraint parameter of the logical channel of the terminal device, where the mapping constraint parameter includes a first parameter and a second parameter, where the first parameter indicates whether the first uplink resource is The data may be used to transmit the logical channel, and the second parameter indicates whether the second uplink resource can be used to transmit data of the logical channel.

The first uplink resource and the second uplink resource may be uplink transmission resources configured by the network device for the terminal device, and the first uplink resource and the second uplink resource may be uplink resources that occur periodically. For example, the first uplink resource may be an uplink resource corresponding to the configured license type 1 (Configured Grant Type 1), and the second uplink resource may be an uplink resource corresponding to the configured license type 2 (Configured Grant Type 2). Of course, the first uplink resource may be configured as a configured license type 1 (Configured Grant Type 1), and the second uplink resource may be a configured license type 2 (Configured Grant Type 2).

In addition, the first message may be a Radio Resource Control (RRC) message, where the first message includes mapping restrictions configured by the network device for the terminal device. It should be noted that the mapping constraint parameter is configured for each logical channel. Therefore, the mapping constraint in the embodiment of the present invention may also be referred to as a logical channel priority processing mapping constraint parameter (LCP mapping restrictions). Each logical channel corresponds to a mapping constraint parameter.

In the embodiment of the present invention, in addition to the foregoing first parameter and the second parameter, the mapping constraint parameter may further include at least one of the following parameters: an allowed subcarrier interval list, a maximum physical uplink shared channel duration, and an allowed serving cell. .

The parameters that may be included in the mapping constraint parameters are described in detail below: (1) First Parameter The first parameter indicates whether the first uplink resource can be used to transmit data of the logical channel. Taking the license type 1 configured by the first uplink resource as an example, it is assumed that the first parameter in the mapping constraint parameter configured for the logical channel A may be “permitted license type 1”, and may indicate whether the configured license type 1 can be used. For transmitting data of logical channel A;

(2) The second parameter indicates whether the second uplink resource can be used to transmit data of the logical channel. Taking the second uplink resource as the configured license type 2 as an example, the second parameter indicating whether the second uplink resource can be used to transmit the data of the logical channel may be: the second parameter indicates whether the configured license type 2 is applicable. Transmitting data of a logical channel, wherein the logical channel can be considered as a logical channel configured with the second parameter;

Optionally, the second parameter may be a logical channel scheduling request barring (logicalChannelSR-Mask). Taking the second uplink resource as the configured license type 2 as an example, the logical channel scheduling request prohibition may indicate whether the configured grant type 2 can be used to transmit data of the logical channel, specifically: if the logical channel is configured with a logical channel scheduling request Forbidden, it indicates that the configured license type 2 can be used to transmit data of the logical channel, and if the logical channel is not configured with logical channel scheduling request prohibition, it indicates that the configured grant type 2 is not available for transmitting data of the logical channel. In some other embodiments, if the logical channel is configured with the logical channel scheduling request barring and the logical channel scheduling request is prohibited to be the first value, the configured permission type 2 can be used to transmit the data of the logical channel, if the logical channel is configured. The logical channel scheduling request is prohibited and the logical channel scheduling request is prohibited to be the second value, indicating that the configured grant type 2 is not available for transmitting data of the logical channel. Alternatively, if the logical channel scheduling request is prohibited in the configuration of the logical channel, the configured permission type 2 may be used to transmit the data of the logical channel, and if the logical channel scheduling request is prohibited in the configuration of the logical channel, the configured permission is indicated. Type 2 may not be used to transmit data for this logical channel.

It should be noted that, in the embodiment of the present invention, the first value is used to indicate that the second uplink resource is used to transmit data of the logical channel of the terminal device, for example, the first value is “true”; the second value is used. The data indicating that the second uplink resource part can be used to transmit the logical channel of the terminal device, for example, the second value is “FALSE”. Of course, in some embodiments, the first value is FALSE and the second value is TRUE; or, the first value is 0, the second value is 1; or, the first value is 1, second The value is 0. The embodiment of the present invention does not specifically limit the first value and the second value, and can indicate whether the second uplink resource unit can be used to transmit data of the logical channel of the terminal device.

(3) The allowed subcarrier spacing list indicates the allowed subcarrier spacing available for transmission. It should be noted that the allowed subcarrier spacing list may include multiple index values, and different index values indicate different subcarrier spacings. Or, the allowed subcarrier spacing list may also include multiple subcarrier spacings. The specific implementation of the allowed subcarrier spacing list is not limited in this embodiment of the present invention. In addition, the plurality of index values included in the allowed subcarrier spacing list may constitute one set, and in the embodiment of the present invention, the set may be referred to as an allowed subcarrier spacing set.

(4) The maximum physical uplink shared channel duration indicates the maximum physical uplink shared channel duration allowed for transmission;

(5) The allowed serving cell indicates the allowed cells available for transmission.

1802. The network device sends the first message to the terminal device.

1803. The terminal device receives a first message sent by the network device.

1804. The terminal device performs logical channel priority processing according to the mapping constraint parameter.

In a specific implementation, the performing, by the terminal device, the processing of the logical channel priority includes: for each uplink resource used for the new transmission, the terminal device selects a logical channel that satisfies the first condition according to the mapping constraint parameter. The first condition includes: when the uplink resource used for new transmission is the second uplink resource, and the logical channel is configured with the second parameter; or, when the uplink resource is used for new transmission The second uplink resource is configured, if the logical channel is configured with the second parameter, and the second parameter is the first value.

It should be noted that, when the terminal device acquires the uplink resource configured by the network device, if the terminal device can use the uplink resource to transmit new data, instead of using the uplink resource to retransmit the already transmitted data, the terminal device may consider that The uplink resource is an uplink resource for new transmission.

Further, after the terminal device determines that an uplink resource is used for the newly transmitted uplink resource, it is also required to determine which logical channel data can be transmitted through the uplink resource. Specifically, the terminal device may determine, according to the mapping constraint parameter configured by each logical channel, whether data of each logical channel can be transmitted through the uplink resource, and finally determine a logical channel that can be transmitted by using the uplink resource, that is, the terminal device according to the mapping constraint. The parameter selects a logical channel that satisfies the first condition. It should be noted that, in the 5G NR, the network device may configure mapping constraint parameters for each logical channel of the terminal device. For each uplink resource configured by the network device for the terminal device, the terminal device needs to traverse the mapping corresponding to all logical channels. The constraint parameter determines that the logical channel of the uplink resource can be used, that is, for each uplink resource, a step is required: "select a logical channel that satisfies the first condition." After the logical channel that can be transmitted by using the uplink resource is selected, the logical channel priority processing specifically includes: the terminal device needs to further determine how much resources are allocated to each logical channel for data transmission of the logical channel, The invention will not be described again.

In some embodiments, the first condition can include sub-condition 1. The sub-condition 1 may be: when the uplink resource is the second uplink resource, the second parameter is configured. When the uplink resource configured by the network device for the terminal device is the second uplink resource, and the logical channel corresponding to the data of the terminal device is configured with the second parameter, the logical channel is considered to satisfy the sub-condition 1, and if the logical channel is not configured with the second If the parameter is considered, the logical channel does not satisfy the sub-condition 1. Alternatively, the sub-condition 1 may be: when the uplink resource is the second uplink resource, if the data of the terminal device is configured with the second parameter, the second parameter is set to the first value. When the uplink resource configured by the network device for the terminal device is the second uplink resource, if the logical channel corresponding to the data of the terminal device is configured with the second parameter and the second parameter is set to the first value TURE, the logical channel is considered to satisfy the sub-attribute. Condition 1, if the logical channel corresponding to the data of the terminal device is configured with the second parameter and the second parameter is not set to the first value TURE (or is set to FALSE), the logical channel is considered not to satisfy the sub-condition 1. Alternatively, the sub-condition 1 may be that the uplink resource configured by the network device for the terminal device is the second uplink resource, and the configuration of the logical channel corresponding to the data of the terminal device has the second parameter. When the uplink resource configured by the network device for the terminal device is the second uplink resource, if the configuration of the logical channel corresponding to the data of the terminal device has the second parameter, the logical channel is considered to satisfy the sub-condition 1, and the data of the terminal device is If there is no second parameter in the configuration of the corresponding logical channel, it is considered that the logical channel does not satisfy the sub-condition 1. It should be noted that the second uplink resource may be the configured license type 2, and the second parameter may be a logical channel scheduling request prohibition (logicalChannelSR-Mask).

In some embodiments, the first condition may further include at least one of the following sub-conditions: sub-condition 2, sub-condition 3, sub-condition 4, and sub-condition 5. The sub-condition 2 may be: if the logical channel corresponding to the data of the terminal device is configured with the allowed sub-carrier spacing list, and the allowed sub-carrier spacing index value set includes the sub-carrier spacing index value associated with the uplink resource, It is considered that the logical channel satisfies the sub-condition 2, and conversely, the logical channel is considered not to satisfy the sub-condition 2.

The sub-condition 3 may be: if the maximum physical uplink shared channel duration is configured corresponding to the data of the terminal device, and the maximum physical uplink shared channel duration is greater than or equal to the maximum physical uplink shared channel duration associated with the uplink resource, the The logical channel satisfies the sub-condition 3, and conversely, the logical channel does not satisfy the sub-condition 3.

The sub-condition 4 may be: if the allowed data cell is configured corresponding to the data of the terminal device, and the allowed serving cell includes the cell associated with the uplink resource, the logical channel is considered to satisfy the sub-condition 4, and vice versa. It is considered that the logical channel does not satisfy the sub-condition 4.

The sub-condition 5 may be: when the uplink resource is the first uplink resource, if the logical channel corresponding to the data of the terminal device is configured with the first parameter and the first parameter is set to the first value, the logical channel is considered to satisfy the sub-condition 5, Otherwise, it is considered that the logical channel does not satisfy the sub-condition 5; or, when the uplink resource is the first uplink resource, if the logical channel corresponding to the data of the terminal device is configured with the permission type 1 allowed to be configured and the permitted permission type 1 is set to The first value is considered to satisfy the sub-condition 5, and the logical channel is considered to not satisfy the sub-condition 5.

It should be noted that the first condition may include at least one of sub-condition 1, sub-condition 2, sub-condition 3, sub-condition 4, and sub-condition 5. For an uplink resource, when the logical channel corresponding to the data of the terminal device satisfies all the sub-conditions in the first condition, the logical channel is considered to satisfy the first condition, and further, the terminal device may use the uplink resource to transmit data on the logical channel.

In the prior art, when the terminal decides whether to trigger the SR, the terminal may refer to the logical channel priority processing mapping constraint parameter to make a judgment, but the terminal device may fail when the decision triggers the SR, for example, the SR should be triggered when the SR is triggered. Causes the data to be too long. The embodiment of the present invention further provides a method for processing a logical channel priority, and the behavior of the terminal device is standardized by adding a new logical channel priority processing mapping constraint parameter, thereby avoiding a fault when the terminal device determines whether the SR is triggered. That is to say, the logical channel priority processing method provided by the embodiment of the present invention can also effectively prevent the terminal device from making a mistake when the SR is triggered.

Specifically, the terminal device may refer to the mapping constraint parameter (LCP) provided by the embodiment of the present invention to determine whether to trigger the scheduling request SR, which specifically includes:

If the terminal device has at least one triggered and not cancelled buffer status report, determining a second condition, the second condition comprising at least one of: having an uplink resource for new transmission and the The transmitted uplink resource does not satisfy the mapping constraint parameter that the logical channel that triggered the buffer status report is configured, and the triggered normal buffer status report and the logical channel scheduling request delay timer are not in the running state. If the second condition is met, the terminal device triggers a scheduling request.

Optionally, the second condition further includes: an unconfigured uplink resource, or the regular buffer status report is not triggered by a logical channel configured with a logical channel scheduling request.

It should be noted that the uplink resource used for the new transmission may be an uplink transmission resource that is periodically configured by the network device for the terminal device, for example, the uplink resource corresponding to the configured license type 1, or the configured license type 2 The corresponding uplink resource, the uplink resource used for the new transmission may also be a dynamically scheduled uplink transmission resource, that is, the uplink transmission resource allocated by the network device to the terminal device by using the downlink control information DCI.

Further, if the uplink resource for the new transmission is the uplink resource corresponding to the configured license type 1, the information about the uplink resource configured for the terminal device configured by the network device by using the RRC message includes the configured license type. After the RRC message sent by the network device is received by the terminal device, the terminal device determines the time when the uplink resource for the new transmission occurs according to the period indicated by the RRC message and the resource location. The frequency location, and the UE may determine the next uplink resource for the new transmission at the current time, that is, the UE may consider that the next uplink resource that is present is available, that is, the next uplink resource that appears is used for the Newly transmitted uplink resources. The current time can understand the time when the terminal device determines whether the second condition is met.

Optionally, if the uplink resource used for the new transmission is the uplink resource corresponding to the configured permission type 2, the information about the uplink resource configured for the terminal device configured by the network device by using the RRC message includes the configuration. After receiving the RRC message sent by the network device, the terminal device may not use the uplink resource indicated by the RRC message (the uplink resource corresponding to the configured license type 2). After the UE receives the DCI of the permission type 2 that is activated by the network device, the UE may determine the uplink for the new transmission according to the configured resource type of the permission type 2 indicated by the DCI and the period indicated by the RRC message. The time-frequency location of the resource, and the terminal device can determine the next uplink resource at the current time, that is, the terminal device can consider that the next uplink resource is available, that is, the next uplink resource that appears is used for the new resource. Upstream resources.

The uplink resource for the new transmission does not satisfy the mapping constraint parameter that the logical channel that triggered the buffer status report is configured, wherein the logical channel that triggers the buffer status report may be a logical channel that triggers the regular buffer status report Regular BSR. Whether the uplink resource satisfies the mapping constraint parameter that the logical channel is configured can be understood as: for each received uplink resource, the terminal device needs to select a logical channel that satisfies the first condition according to the mapping constraint parameter corresponding to each logical channel. If the mapping constraint parameter configured according to the logical channel determines that the first condition is met, the uplink resource is considered to meet the mapping constraint parameter configured by the logical channel, and if the mapping constraint parameter configured according to the logical channel determines that the first condition is not met, the uplink is considered to be uplink. The resource does not satisfy the mapping constraint parameter that the logical channel is configured.

It should be noted that the “Regular Cache Status Report” may be a regular cache status report in “At least one triggered and not canceled cache status report”. A regular cache status report with a trigger can be understood as a regular cache status report with a trigger, or a regular cache status report with at least one trigger. The cache status report may include a regular cache status report Regular BSR, a padding buffer status report Padding BSR, and a periodic buffer status report Periodic BSR. When any logical channel belonging to a logical channel group has no transmittable data, a logical channel belonging to the logical channel group has data arriving, and a regular BSR is triggered; or, there is a higher priority belonging to the logical channel group. The logical channel has data arrival, it will trigger the regular BSR; or, the BSR triggered by the buffer status report retransmission timer retxBSR-Timer timeout is a regular BSR.

The scheduling request delay timer is a timer set for a MAC entity of a terminal device. During the scheduling request delay timer operation, the terminal device cannot trigger the SR, and when the scheduling request delay timer is not in the running state, the terminal device has the The SR may be triggered.

In addition, when the logical channel is configured with the logical channel prohibiting scheduling request, the logical channel cannot trigger the SR, and only the logical channel is not configured with the logical channel to prohibit the scheduling request, and the logical channel may trigger the SR. Generally, when the terminal device has a voice service on a certain logical channel, the uplink resource that the network device can configure for the terminal device may be: an uplink resource corresponding to the configured license type 2, because the network device knows the logic of the voice service of the terminal device. The service period and size of the channel, for the data on the logical channel of the voice service, does not need to request resources through the SR, so the network device can disable the scheduling request by configuring the logical channel of the logical channel of the voice service, thereby preventing The logical channel of the voice service triggers the SR, but other logical channels can still allow the SR to be triggered normally. It should be noted that the logical channel triggers the SR, which can be understood as: the logical channel has a triggered BSR, but the BSR cannot trigger the SR further.

The following is an example in which the uplink resource used for the new transmission by the network device is configured as the configured permission type 2 (that is, the uplink resource used for the new transmission is the uplink resource corresponding to the configured license type 2), and the implementation of the present invention is introduced. The method provided by the example. Referring to FIG. 19, the current time is T, the uplink resource that appears before time T is uplink resource 1, and the uplink resource that appears after time T is uplink resource 2.

Referring to mode (a) in FIG. 19, in the prior art, the UE determines that the uplink resource 2 is an uplink resource available for new transmission at time T. Further, the UE performs step S2 and step S3. Further, the uplink resource that can be used for the new transmission may meet the mapping constraint parameter of the logical channel priority processing corresponding to the logical channel that triggers the regular BSR, even if there is a regular BSR triggered and a logical channel scheduling request delay timer, and the following is available: The uplink resource of the new transmission is not configured or triggered. The regular BSR is not triggered by the logical channel configured with the logical channel scheduling request. In this case, the UE does not trigger the SR. Since the uplink resource 2 has a long time from the time T, it means that the BSR triggered by the logical channel cannot trigger the SR during this long time, that is, the dynamically scheduled resource cannot be requested more quickly. At this time, the data of the logical channel can be sent only after the long-term resource 2 resources are waited for a long time, which will result in a large delay of the data of the logical channel.

Referring to mode (b) in FIG. 19, in the embodiment of the present invention, if the terminal device has at least one triggered and not cancelled buffer status report, the terminal device may decide whether to trigger the SR by using the following second condition:

Condition W1: if there is an uplink resource available for new transmission, a BSR MAC CE is generated;

Condition W2: condition W2a, if there is no uplink resource available for new transmission; or,

The condition W2b, if the uplink resource available for the new transmission does not satisfy the mapping constraint parameter of the logical channel priority processing corresponding to the one or more logical channels that trigger the BSR; wherein the mapping constraint parameter includes at least the first parameter and the second parameter.

Condition W3: If a regular Buffer Status Report (Regular BSR) is triggered and the logical channel scheduling request delay timer (logicalChannelSR-DelayTimer) is not running.

In a specific implementation, when there is at least one triggered BSR, and the triggered BSR is not cancelled, if the UE determines that there is an uplink resource available for new transmission, that is, the condition W1 is satisfied, the UE generates a BSR MAC CE, condition W1 and condition W2- W3 is relatively independent, and the UE further judges the condition W2-W3 regardless of the judgment result of the condition W1. If neither the condition W2a nor the condition W2b is satisfied, the SR is not triggered; if any of the condition W2a and the condition W2b is satisfied, it is further determined whether or not the condition W3 is satisfied. If condition W3 is not satisfied, SR is not triggered; if condition W3 is satisfied, SR is triggered.

In the prior art, when determining the uplink resource for the new transmission (the uplink resource corresponding to the configured license type 2), and entering the condition W2b, the terminal device needs to further determine whether the uplink resource available for the new transmission satisfies one of the triggered BSRs. Or mapping constraint parameters of logical channel priority processing corresponding to multiple logical channels. In the prior art, the mapping constraint parameters include a first parameter (such as "allowed configured permission type 1"), an allowed subcarrier interval list, a maximum physical uplink shared channel duration, and an allowed serving cell. The terminal device determines whether the first condition is met according to the mapping constraint parameter corresponding to the logical channel. In the prior art, if it is determined that all the sub-conditions in the first condition are met, the sub-condition 2, the sub-condition 3, the sub-condition 4, and the sub-condition are satisfied. Condition 5, that is, the condition W2b is not satisfied. The SR is not triggered even if the condition W3 is satisfied.

However, in the embodiment of the present invention, referring to FIG. 19, when determining the uplink resource for the new transmission (the uplink resource corresponding to the configured license type 2), and entering the foregoing condition W2b, the terminal device needs to further determine the uplink resource that can be used for the new transmission. Whether the mapping constraint parameter of the logical channel priority processing corresponding to one or more logical channels of the BSR is met is met. At this time, the mapping constraint parameter includes the first parameter in the prior art (such as "permitted permission type 1"), the allowed subcarrier interval list, the maximum physical uplink shared channel duration, the allowed serving cell, and the Two parameters. The terminal device determines whether the first condition is met according to the mapping constraint parameter corresponding to the logical channel. At this time, if it is determined that the sub-condition 2, the sub-condition 3, the sub-condition 4, and the sub-condition 5 in the prior art satisfying the first condition are further required, It is further determined whether the sub-condition 1 is satisfied, and if the sub-condition 1 is not satisfied, it is considered that the first condition is not satisfied, that is, the condition W2b is satisfied. If the condition W3 is further satisfied, the SR is triggered.
