Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Currently, in a Long Term Evolution (Long Term Evolution, hereinafter abbreviated as LTE) system, a basic uplink scheduling procedure is shown in fig. 1. When the UE has uplink data to be sent, the UE sends an SR on a specified SR resource, and the base station learns that the UE has the uplink data to be sent through the SR; a base station schedules UE uplink transmission, and configures a small part of resources for the UE for transmitting BSR; the UE sends BSR (possibly containing partial data) to the base station on an uplink grant (UL grant) scheduled by the base station; the base station knows how much uplink data the UE has according to the BSR, and then the base station performs scheduling data according to the amount of uplink data to be sent by the UE and the priority of the data service, that is, resources are allocated to the UE, and the UE sends data (data) in the UL grant scheduled by the base station.

As can be seen from the above description, the role of the BSR is: information to tell the base station how much data the UE has to send. In other words, the BSR is used to inform the base station UE of the amount of data to be sent.

Currently, the BSR is reported according to a Logical Channel Group (LCG). At present, under the condition that the UE side already has LCG data valid, if there is no LCG data with higher priority coming, reporting of BSR is not triggered even if there is data to be sent by LCGs with the same priority and low priority, then there is a scheme in an enhanced scheme of a BSR triggering mechanism, which is: this restriction is removed, i.e. the reporting of the BSR is triggered whenever new data comes and the buffer status is updated.

However, the above solution has the disadvantages: the burden of reporting by the UE is greatly increased. For example, if the buffered data size (buffer size) of the UE changes slightly and there is new data to be transmitted from the LCG with the logical priority, the base station may normally schedule the data of the UE without the information, for example, the base station may be a larger UL grant for the UE.

Another enhancement scheme for the BSR triggering mechanism is: the BSR report is reported per each QoS flow or IP flow.

Therefore, how to effectively enhance the BSR trigger mechanism on the premise of balancing the reporting burden of the UE is an urgent problem to be solved at present.

Based on this, in various embodiments of the invention: a base station configures configuration information related to triggering BSR reporting for UE; sending the configuration information to the UE; the configuration information is used for setting a trigger condition reported by a BSR when data of a first logic channel of the UE is valid by the UE; when the data of the first logical channel is valid, the UE judges whether a trigger condition for BSR reporting is met; if the trigger condition of the BSR report is met, triggering the BSR report; otherwise, the BSR report is not triggered.

Example one

The BSR triggering method provided by the embodiment of the invention is applied to a base station. In the LTE system, the base station is an evolved Node B (eNB). In a fifth Generation mobile communication technology (5th-Generation, hereinafter referred to as 5G) system, the base station is a 5G node b (gnb).

Fig. 2 is a flow chart of a BSR-based processing method at a base station side according to an embodiment of the present invention, and as shown in fig. 2, the method includes:

step 201: configuring configuration information related to triggering BSR reporting for UE;

here, the configuration information is used for the UE to set a trigger condition for BSR reporting when data of the first logical channel of the UE is valid.

In other words, the trigger condition for BSR reporting refers to: and after the first logic channel with valid data triggers one BSR report, triggering the next BSR report.

Wherein the data valid means: the UE has reported a BSR for a first logical channel, and the base station has allocated a resource (UL grant) for data of the first logical channel, where the data of the first logical channel is used for next transmission, that is, the data of the first logical channel is valid data for transmission.

In actual application, the base station may configure the configuration information for the UE according to a reporting policy of the BSR.

Step 202: and sending the configuration information to the UE.

Here, after receiving the configuration information, the UE may set a trigger condition for BSR reporting when data of the first logical channel of the UE is valid according to the configuration information.

In practical application, a change threshold, that is, a change threshold, of the buffer size may be configured for the UE, so as to constrain the reporting frequency of the BSR.

Based on this, in an embodiment, the configuration information includes a buffer change threshold, and the trigger condition reported by the BSR includes that a buffer change amount of the data of the UE reaches the buffer change threshold. That is, the UE triggers the report of the BSR when the buffer variation of the added data reaches the buffer variation threshold.

The size of the buffer amount change threshold value can be set according to needs.

During actual application, a corresponding buffer storage amount change threshold value is configured for each logic channel.

Based on this, in an embodiment, each logical channel of the UE corresponds to a buffer change threshold, and the trigger condition reported by the BSR includes that a buffer change amount of data of at least one logical channel of the UE reaches the corresponding buffer change threshold. That is, the UE triggers reporting of the BSR when the buffer variation of the data of at least one logical channel reaches the corresponding buffer variation threshold.

In practical applications, the configured buffer amount change threshold may also be for a logical channel with a priority lower than and/or equal to the first logical channel. That is to say, the buffer amount change threshold represents a change threshold of a buffer amount of data of a low-priority logical channel of the UE, the trigger condition reported by the BSR includes that a buffer variation amount of the data of the low-priority logical channel reaches the buffer amount change threshold, and the low-priority logical channel is a logical channel with a priority equal to and/or lower than the first logical channel. In other words, when the total buffer variation of the data of the low-priority logical channel reaches the buffer variation threshold, the UE triggers the report of the BSR.

Here, the buffer amount change threshold may further characterize a buffer amount change threshold of data of other logical channels of the UE besides the first logical channel, where the trigger condition for BSR reporting includes that a buffer change amount of the data of the other logical channels reaches the buffer amount change threshold, and the other logical channels are logical channels with priorities equal to and/or lower than that of the first logical channel. At this time, when the buffer variation of the data of the other level of logical channels reaches the buffer variation threshold, the UE triggers reporting of a BSR.

The current BSR is reported according to a logical channel group, the logical channel group of the UE is divided into 4 groups at most, and there are two BSR formats, one format is a Short BSR and a shortened BSR MAC CE shown in fig. 3, and the other format is a Long BSR MAC CE shown in fig. 4. Wherein, the buffer size of the LCG with the highest priority is reported by the Short BSR and trunked BSR MAC CE, and the Long BSR MAC CE is used for the buffer size of all 4 logical channel groups.

Therefore, the priority of the logical channel may be determined in combination with the priority of the corresponding LCG.

In practical application, the buffer amount change threshold value can be configured by considering QoS flow or IP flow.

Based on this, in an embodiment, each QoS flow or IP flow of the UE corresponds to one buffer change threshold, and the trigger condition reported by the BSR includes that a buffer change amount of data of at least one QoS flow or IP flow of the UE reaches the corresponding buffer change threshold. That is, when the buffer variation amount of data with at least one QoS flow or IPflow reaches the corresponding buffer variation threshold, the UE triggers reporting of the BSR.

Here, it has been decided to introduce the concept of QoS flow (see RAN2#96 in the discussion of 5G NR) in the discussion of 5G new air interfaces (NR), and as shown in fig. 5A, 5B, 6A, and 6B, multiple QoS flows of uplink and downlink can be mapped to one logical channel.

At least one IP flow may be mapped into one QoS flow.

In practical application, the duration of the prohibit timer may be configured for the UE, so as to constrain the reporting frequency of the BSR.

Based on this, in an embodiment, the configuration information includes a duration of a prohibit timer, and the trigger condition for reporting by the BSR includes that the prohibit timer is overtime and the UE has data to send. In other words, when the prohibit timer expires and the UE has data to send, the UE triggers the reporting of a BSR.

In practical application, the configured prohibit timer duration may also be for a logical channel with a priority lower than and/or equal to the first logical channel. Specifically, the prohibit timer represents a timer corresponding to a low-priority logical channel of the UE, and the trigger condition reported by the BSR includes that the prohibit timer is overtime and the low-priority logical channel has data to be sent; the low priority logical channel is a logical channel with a priority equal and/or equal to the first logical channel. That is, when the prohibit timer expires and the low priority logical channel has data to send, the UE triggers the reporting of BSR.

In actual application, the prohibit timer duration may also represent timer durations corresponding to other logical channels of the UE except the first logical channel, and the trigger condition reported by the BSR includes that the prohibit timer is overtime and the other logical channels have data to be sent; the other logical channels are logical channels having a priority lower than and/or equal to the first logical channel.

That is, configuring a prohibit timer duration for the other logical channels; at this time, when the prohibit timer is overtime and the other logical channels have data to send, the UE triggers the report of the BSR.

The prohibit timer duration may also be configured for each logical channel of the UE.

Based on this, each logical channel of the UE corresponds to one prohibit timer, and the trigger condition reported by the BSR includes that the prohibit timer corresponding to at least one logical channel of the UE is overtime and the logical channel has data to be sent. That is, the UE triggers the reporting of BSR when the prohibit timer for at least one logical channel expires. Of course this logical channel is to be sent.

Here, the prohibit timer duration may be configured as needed.

In practical application, a specific QoS flow or IP flow may be configured for the UE, so as to restrict the reporting frequency of the BSR.

Based on this, the configuration information includes a specific QoS flow or IP flow, and the trigger condition reported by the BSR includes that the specific QoS flow or IP flow of the UE has data to be sent. That is, when a UE has a specific QoS flow or IPflow with data to send, the UE triggers the reporting of BSR.

Wherein a specific QoS flow or IP flow can be configured for the priority of the logical channel of the UE.

Based on this, in an embodiment, the specific QoS flow or IP flow represents QoS flow or IP flow on a low-priority logical channel of the UE, and the triggering condition reported by the BSR includes that the specific QoS flow or IP flow on the low-priority logical channel has data to be sent; the low priority logical channel is a logical channel having a priority equal to and/or lower than the first logical channel. That is, or, the UE triggers the reporting of BSR when a specific QoS flow or IPflow on the low priority logical channel has data to send.

Wherein a specific QoS flow or IP flow may also be configured for other low priority channels of the UE than the first logical channel.

Based on this, the specific QoS flow or IP flow characterizes QoS flow or IP flow on other logical channels of the UE except the first logical channel, and the trigger condition reported by the BSR includes that the specific QoS flow or IP flow on the other logical channels has data to be sent; the other logical channels are logical channels having a priority lower than and/or equal to the first logical channel. In other words, the UE triggers the reporting of BSR when a specific QoS flow or IP flow on other logical channels has data to send.

In another embodiment, a specific QoS flow or IP flow may also be configured on a per logical channel basis; at this time, each logical channel of the UE corresponds to a specific QoS flow or IP flow, and the triggering condition reported by the BSR includes that the specific QoS flow or IP flow on at least one logical channel of the UE has data to be sent. In other words, the UE triggers the reporting of BSR when there is data of at least one logical channel to be sent being data of a specific QoS flow or IP flow.

Specific QoS flow or IP flow may also be configured based on each logical channel group, at this time, each logical channel group of the UE corresponds to one specific QoS flow or IP flow, and the triggering condition reported by the BSR includes that data is to be sent in the specific QoS flow or IP flow on at least one logical channel group of the UE. That is, when there is data of at least one logical channel group to be transmitted that is data of a specific QoS flow or IP flow, the UE triggers reporting of a BSR.

Wherein, for a specific QoS flow or IP flow, it can be embodied by Identification (ID) corresponding to the QoS flow or IP flow.

As can be seen from the above description, in practical application, the configuration information may be configured for the priority of the logical channel of the UE.

Based on this, in an embodiment, the specific implementation of step 201 includes:

Here, in an embodiment, the configuration information includes a cache buffer amount change threshold.

Specifically, the buffer change threshold represents a change threshold of a buffer of data of a low-priority logical channel of the UE, and the trigger condition reported by the BSR includes that a buffer variation of the data of the low-priority logical channel reaches the buffer change threshold.

The buffer amount change threshold may also characterize buffer amount change thresholds of data of other logical channels of the UE except the first logical channel, where the trigger condition reported by the BSR includes that a buffer variation amount of the data of the other logical channels reaches the buffer amount change threshold, and the other logical channels are logical channels with priorities equal to and/or lower than that of the first logical channel.

In one embodiment, the configuration information includes a duration of a prohibit timer.

Specifically, the prohibit timer represents a timer corresponding to a low-priority logical channel of the UE, and the trigger condition reported by the BSR includes that the prohibit timer is overtime and the low-priority logical channel has data to be sent.

alternatively, the first and second electrodes may be,

a first QoS flow of the UE has data to be sent, and other QoS flows in a logic channel where the first QoS flow is located have no data to be sent;

alternatively, the first and second electrodes may be,

a first QoS flow of the UE has data to send, and the priority of the first QoS flow is higher than the priority of other QoS flows having data to send.

The first QoS flow may be any QoS flow of the UE;

For example, logical channel 1 has Qos flow1 and Qos flow 2, where the priority of Qos flow1 is 2 and the priority of Qos flow 2 is 3; the logical channel 2 has Qos flow3 and Qos flow 4, the priority of Qos flow3 is 2, and the priority of Qos flow 4 is 3.

If the trigger condition for reporting the BSR is as follows: when the QoS flow1 in the logical channel 1 has data to be sent, and the QoS flow 2 also has data to be sent, determining whether the priority of the QoS flow1 is greater than the priority of other QoS flows having data to be sent in the logical channel 1, that is, determining whether the priority of the QoS flow1 is greater than the priority of the QoS flow 2 in the logical channel 1, and if so, triggering BSR reporting; otherwise, the BSR report is not triggered.

If the trigger condition for reporting the BSR is as follows: when the QoS flow1 in the logical channel 1 has data to be transmitted, and the QoS flow 2, the QoS flow3 and the QoS flow 4 all have data to be transmitted, determining whether the priority of the QoS flow1 is greater than the priority of the other QoS flows having data to be transmitted, that is, determining whether the priority of the QoS flow1 is greater than the priorities of the QoS flow 2, the QoS flow3 and the QoS flow 4, and if so, triggering BSR to report; otherwise, the BSR report is not triggered.

After the base station allocates the configuration information to the UE, when a trigger condition for reporting a BSR is satisfied, the UE sends a BSR to the base station to request allocation of a resource for transmitting a first BSR (BSR satisfying the trigger condition); after receiving the request, the base station allocates resources for the first BSR of the UE; and receiving a first BSR sent by the UE on the allocated resources.

Correspondingly, the embodiment of the invention also provides a BSR-based processing method which is applied to the UE.

step 701: when the data of the first logic channel of the UE is effective, judging whether a trigger condition for reporting the BSR is met;

here, in practical applications, before the step is executed, the method may further include:

acquiring configuration information related to triggering BSR reporting;

and setting the trigger condition by using the configuration information.

The configuration information related to the BSR reporting may be obtained by receiving the configuration information sent by the base station. Or, the UE may already agree with the base station, at this time, the UE already locally stores the configuration information, and the UE may acquire the configuration information only by reading the configuration information from a storage medium.

Step 702: if the trigger condition of the BSR report is met, triggering the BSR report; otherwise, the BSR report is not triggered.

In an embodiment, the trigger condition reported by the BSR includes that a buffer variation of the data of the UE reaches a buffer variation threshold; the specific implementation of step 701 includes:

judging whether the cache variation of the data of the UE reaches the cache variation threshold;

and when the buffer variation of the data of the UE reaches the buffer storage variation threshold, the UE triggers the report of the BSR.

Of course, when the buffer variation of the data of the UE reaches the buffer variation threshold, the UE does not trigger the report of the BSR.

In actual application, a corresponding buffer storage amount change threshold value is configured for each logical channel.

Based on this, the trigger condition reported by the BSR includes that the buffer variation of the data of at least one logical channel of the UE reaches a corresponding buffer variation threshold;

And when the buffer variation of the data of at least one logic channel of the UE does not reach the corresponding buffer storage variation threshold, not triggering the report of the BSR.

The configured buffer level change threshold may also be for logical channels with a priority lower than and/or equal to the first logical channel.

Based on this, the trigger condition reported by the BSR includes that the buffer variation of the data of the low-priority logical channel reaches the buffer variation threshold; the low priority logical channel is a logical channel having a priority equal to and/or lower than the first logical channel;

and when the total buffer variation of the data of the low-priority logic channel reaches the buffer storage variation threshold, the UE triggers the report of the BSR.

Here, when the total amount of variation in the buffer of the data of the low-priority logical channel does not reach the buffer change threshold, the UE does not trigger the report of the BSR.

The triggering condition reported by the BSR comprises that the buffer variation of data of other logic channels of the UE except the first logic channel reaches a buffer storage variation threshold; the other logical channels are logical channels with priority equal to and/or lower than the first logical channel;

And when the total buffer variation of the data of the other logical channels does not reach the buffer storage variation threshold, the UE does not trigger the report of the BSR.

Based on this, in an embodiment, the trigger condition reported by the BSR includes that a buffer variation amount of data of at least one QoS flow or IP flow of the UE reaches a corresponding buffer variation threshold;

judging whether the cache variation of at least one QoS flow or IP flow data of the UE reaches the corresponding cache variation threshold value;

and when the buffer variation of at least one piece of QoS flow or IP flow data of the UE reaches the corresponding buffer storage variation threshold, triggering the report of BSR by the UE.

Here, when there is no buffer variation of data of at least one QoS flow or IP flow of the UE reaching the corresponding buffer variation threshold, the UE does not trigger reporting of a BSR.

In practical application, the duration of the prohibit timer may be configured for the UE.

Based on this, in an embodiment, the trigger condition for BSR reporting includes that the prohibit timer is overtime and the UE has data to send;

the specific implementation of step 701 includes:

and triggering the report of the BSR when the data to be sent and the forbidden timer are overtime.

Of course, when the prohibit timer does not time out, the reporting of the BSR is not triggered. That is, the report of BSR is not triggered when the logical channel has data to send before the prohibit timer expires.

Wherein the prohibit timer duration may also be for logical channels having a priority lower than or equal to the first logical channel.

Based on this, the trigger condition reported by the BSR includes that the prohibit timer is overtime and the low-priority logical channel has data to be sent; the low priority logical channel is a logical channel with a priority equal and/or equal to the first logical channel;

The logic channel to be sent is the low priority logic channel, and the report of BSR is triggered when the timer is forbidden to overtime; the logical channel to be sent is the low priority logical channel, and the report of the BSR is not triggered when the prohibit timer does not time out.

Wherein, in practical application, the following steps can be also included: the trigger condition reported by the BSR comprises that a prohibit timer is overtime and other logic channels of the UE except the first logic channel have data to be sent; the other logical channels are logical channels with a priority lower than and/or equal to the first logical channel;

judging whether the logic channel of the UE to be sent with the data is the other logic channel or not;

And when the logical channel of the data to be sent is the other logical channel and the prohibit timer is overtime, triggering the report of the BSR, and when the logical channel of the data to be sent is the other logical channel and the prohibit timer is not overtime, not triggering the report of the BSR.

A corresponding timer duration may also be configured for each logical channel of the UE.

Based on this, the trigger condition reported by the BSR includes that a prohibit timer corresponding to at least one logical channel of the UE is overtime and the logical channel has data to be sent;

and judging whether the prohibition timer corresponding to at least one logical channel is overtime or not in the UE, wherein the logical channel has data to be sent.

And when the prohibition timer corresponding to at least one logic channel is overtime, triggering the report of the BSR, and when the prohibition timer corresponding to at least one logic channel is not overtime, not triggering the report of the BSR.

Wherein, the method can also comprise:

In practical application, a specific QoS flow or IP flow may be configured for the UE.

Based on this, the trigger condition reported by the BSR includes that data to be sent is in a specific QoS flow or IP flow of the UE;

And when the data to be sent is data of specific QoS flow or IP flow, triggering the report of BSR.

And when the data to be sent is not the data of the specific QoS flow or the IP flow, not triggering the BSR.

Here, a specific QoS flow or IP flow may be configured for the priority of the logical channel of the UE. Based on this, the trigger condition reported by the BSR includes that data to be sent is in a specific QoS flow or IP flow on a low-priority logical channel; the low priority logical channel is a logical channel having a priority equal to and/or lower than the first logical channel;

And when the priority of the logical channel of the data to be sent is lower than and/or equal to the priority of the first logical channel and the data to be sent is data of a specific QoS flow or IP flow, triggering the report of the BSR. And when the priority of the logical channel of the data to be sent is lower than and/or equal to the priority of the first logical channel and the data to be sent is not the data of the specific QoSflow or IP flow, the report of the BSR is not triggered.

The method can also be as follows: when the logic channel of the data to be sent is the logic channel with the priority equal to the first logic channel and the data to be sent is the data of a specific QoS flow or IP flow, triggering the report of a BSR;

The trigger condition reported by the BSR further includes that data to be sent is subjected to specific QoS flow or IP flow on other logical channels of the UE except the first logical channel; the other logical channels are logical channels with a priority lower than and/or equal to the first logical channel;

A specific QoS flow or IP flow may also be configured for each logical channel or each logical channel group. Based on this, the trigger condition reported by the BSR includes that data is to be sent on a specific QoS flow or IP flow on at least one logical channel of the UE; the judging whether the data to be sent is data of specific QoS flow or IP flow includes:

and judging whether the data to be sent of at least one logical channel is data of specific QoS flow or IP flow.

It should be noted that: the specific processing procedures of the base station and the UE are described in detail above, and are not described herein again.

The processing method based on the BSR provided by the embodiment of the invention configures configuration information related to the report of the BSR for UE; sending the configuration information to the UE; the configuration information is used for setting a trigger condition reported by a BSR when data of a first logic channel of the UE is valid by the UE; when the data of the first logical channel is valid, the UE judges whether a trigger condition for BSR reporting is met; if the trigger condition of the BSR report is met, triggering the BSR report; otherwise, the BSR reporting is not triggered, and the triggering of the BSR reporting is controlled through a triggering condition when the data of the first logic channel is effective, so that the triggering of the BSR reporting can be effectively realized on the premise of balancing the reporting burden of the UE.

In addition, the triggering control of the BSR reporting is realized by configuring a buffer change threshold, a specific QoS flow or an IP flow, so that the triggering of the BSR reporting can be flexibly realized.

Example two

On the basis of the first embodiment, this embodiment describes in detail a specific process of configuring a buffer amount change threshold for a UE to trigger a BSR.

In this embodiment, the base station configures a buffer size change threshold, such as 30bytes, for the UE. After the UE has triggered BSR reporting, that is, after the UE has reported BSR to the base station, if the UE side data reaches the buffer, which causes buffer change, and the increased buffer size exceeds 30bytes, the UE triggers BSR reporting.

In addition, in practical applications, the configuration of the buffer size change threshold may be for the existing data logical channels equal to and/or lower than the existing data logical channel (the logical channel has reported the BSR), in this case, for example, assuming that the priority of the current logical channel LC1 is 1, and the priorities of the logical channels LC 2 and LC3 are 2 and 3, respectively, after the BSR is triggered when the LC1 data arrives, the arrival of data on the logical channels LC 2 and LC3 is 20bytes after a certain time, at this time, the UE determines that the priorities of the logical channels LC 2 and LC3 are lower than the priority of the logical channel LC1, and the change amount of the buffer size does not exceed the threshold, so the BSR is not triggered. After a further period of time, the UE finds: after the BSR is sent last time, the data arriving in the logic channels LC 2 and LC3 are accumulated to reach 30bytes, and at this time, the UE triggers the BSR to report.

This buffer size change threshold may also be configured for each logical channel. For example, the threshold of the logical channel LC 2 is 20bytes, and the threshold of the logical channel LC3 is 30 bytes. At this time, when the UE determines that the amount of change in the buffer size caused by the data arriving on the logical channel LC 2 exceeds 20bytes, the BSR is triggered; correspondingly, when the UE determines that the variation of the buffer size caused by the data arriving on the logical channel LC3 exceeds 20bytes, the UE triggers the report of the BSR.

The Buffer size change threshold may also be configured per Qos flow. The buffer size change threshold may also be increased or changed by more than the last time the buffer size was reported, for example by 20%. That is, when the UE determines that the buffer size variation is increased by 20% compared with the buffer size variation in the last BSR reporting, the UE triggers BSR reporting.

As can be seen from the above description, in this embodiment, the BSR is triggered by configuring the buffer storage amount change threshold, so that the triggering of BSR reporting can be effectively implemented on the premise of balancing the reporting burden of the UE.

In addition, the triggering of the BSR reporting can be flexibly realized.

EXAMPLE III

On the basis of the first embodiment, this embodiment describes in detail a specific processing procedure for configuring a prohibit timer (BSR trigger prohibit timer) for a UE to trigger a BSR.

In this embodiment, the base station configures a BSR trigger prohibit timer for the UE, for example, the duration is 20 ms.

When the UE triggers BSR reporting, when a logic channel with a priority greater than that of the logic channel with existing data (reported BSR) has data coming (data to be sent), the UE directly triggers BSR reporting without considering whether the BSR trigger prohibit timer is overtime or not.

When data arrives in a logical channel with the priority equal to and/or less than the priority of the logical channel with the data (reported BSR), the UE judges whether the BSR trigger prohibit timer is overtime or not, if not, the BSR is not triggered, and if the BSR trigger prohibit timer is overtime, the BSR is triggered. The BSR trigger prohibit timer may be started when the BSR sends a candidate or triggers the BSR, and the UE allows triggering the BSR after the BSR trigger prohibit timer expires, and restarts the BSR after the BSR is sent.

This BSR trigger prohibit timer may also be configured for each logical channel of the UE. At this time, when data arrives in the logical channel, whether the timer for the logical channel is overtime is judged, if yes, the BSR is triggered, otherwise, the BSR is not triggered.

As can be seen from the above description, in this embodiment, the BSR is triggered by configuring the prohibit timer, so that the BSR can be effectively triggered on the premise of balancing the reporting burden of the UE.

In addition, the triggering of the BSR reporting can be flexibly realized.

Example four

On the basis of the first embodiment, this embodiment describes in detail a specific process of configuring QoS flow for a UE to trigger BSR.

Specifically, the base station configures the UE with a specific QoS flow of a logical channel with the same priority or a lower priority than the logical channel of the existing data, so as to trigger the reporting of the BSR. The reporting of BSR is allowed to be triggered when data arrives at a particular Qos flow of the same or low logical channel priority.

In this case, after data of a logical channel arrives, the UE first determines the priority of the logical channel, and if the priority of the logical channel on which the data arrives is equal to or lower than the priority of the logical channel on which the data already arrives, the UE further determines whether a configured QoS flow (specific QoS flow) has data to arrive, thereby determining whether to trigger a BSR. For example, assuming that the base station configures the UE with QoS flow permission triggering BSR with QoS flow ID of 5, assuming that logical channel 1 and logical channel 2 have the same priority, as shown in fig. 6A, logical channel 1 carries QoS flows 1, 2 and 3, and logical channel 2 carries QoS flows 4, 5 and 6, as shown in fig. 6B. There is initially no data on logical channel 1 and logical channel 2, and a BSR is triggered when data arrives on QoS flow 1. After a period of time, the QoS flow 4 has data coming, the UE determines that no data with high logical channel priority comes, and the QoS flow is 4, and does not satisfy the configuration trigger BSR QoS flow5, so that the report of BSR is not triggered. After a while, the data with QoS flow ID of 5 comes, at this time, although no data with higher logical channel priority comes, the QoS flow5 is a special configuration of the base station, so the UE triggers BSR reporting.

The reported BSR may or may not carry the QoS flow identifier.

In actual application, the base station configures a QoS flow permission trigger BSR with a UE QoS flow ID of x, and may configure and lower a logical channel priority based on each same logical channel priority, for example, report of a BSR may be triggered again for the same logical channel priority and data comes with a QoS flow ID of x, and if the data with a QoS flow ID of x is carried on a logical channel with a lower priority, the BSR is not permitted to be triggered.

When the base station configures a specific QoS flow for the UE to trigger the BSR, the base station may also configure the specific QoS flow based on the logical channel or the LCG, and in this case, the UE may trigger BSR reporting of the logical channel or the LCG as long as it monitors that data of the specific QoS flow increases.

As can be seen from the above description, in this embodiment, the BSR is triggered by configuring a specific QoS flow, so that the BSR can be effectively triggered on the premise of balancing the reporting burden of the UE.

In addition, the scheme of the embodiment of the invention can realize flexible BSR triggering.

EXAMPLE five

In order to implement the method according to the embodiment of the present invention, the embodiment provides a BSR-based processing apparatus, which is disposed in a base station. Wherein, in the LTE system, the base station is an eNB. In a 5G system, the base station is a gbb.

As shown in fig. 9, the apparatus includes:

a allocating unit 91, configured to configure configuration information related to triggering BSR reporting for the UE;

a first sending unit 92, configured to send the configuration information to the UE; the configuration information is used for the UE to set a trigger condition for BSR reporting when the data of the first logical channel of the UE is valid.

Based on this, the configuration information includes a buffer change threshold, and the trigger condition reported by the BSR includes that the buffer change amount of the data of the UE reaches the buffer change threshold. That is, the UE triggers the report of the BSR when the buffer variation of the added data reaches the buffer variation threshold.

Based on this, each logical channel of the UE corresponds to a buffer amount change threshold, and the trigger condition reported by the BSR includes that the buffer variation amount of the data of at least one logical channel of the UE reaches the corresponding buffer amount change threshold. That is, the UE triggers reporting of the BSR when the buffer variation of the data of at least one logical channel reaches the corresponding buffer variation threshold.

The current BSR is reported according to a logical channel group, the logical channel group of the UE is divided into 4 groups at most, and there are two BSR formats, one format is Short BSR and Truncated BSR MAC CE shown in fig. 3, and the other format is Long BSR MAC CE shown in fig. 4. Wherein, the buffer size of the LCG with the highest priority is reported by the Short BSR and trunked BSR MAC CE, and the Long BSR MAC CE is used for the buffer size of all 4 logical channel groups.

Here, it has been decided in the discussion of 5G NR to introduce the concept of QoS flow (see RAN2#96 in the discussion of 5G NR), and as shown in fig. 5A, 5B, 6A, 6B, multiple QoS flows of uplink and downlink can be mapped into one logical channel.

At least one IP flow may be mapped into one QoS flow.

Here, the prohibit timer duration may be configured as needed.

Based on this, in an embodiment, the configuration information includes a specific QoS flow or IP flow, and the triggering condition reported by the BSR includes that data is to be sent in the specific QoS flow or IP flow of the UE. That is, when a specific QoS flow or IP flow of a UE has data to send, the UE triggers the reporting of BSR.

Wherein, for a specific QoS flow or IP flow, it can be embodied by ID corresponding to QoS flow or IP flow.

The allocation unit 91 is specifically configured to:

configuring the configuration information for the low priority logical channel.

Here. In one embodiment, the configuration information includes a cache buffer size change threshold.

The configuration information includes a duration of a prohibit timer.

Here, the prohibit timer duration may be configured as needed.

alternatively, the first and second electrodes may be,

the first QoS flow may be a specific QoS flow of the UE;
