Detailed Description
Based on the uplink radio resource allocated by the uplink grant indication, the UE needs to decide the total amount of data of each logical channel included in the new MAC PDU, and if necessary, the UE also allocates a resource for a MAC control element (MAC control element). Specifically, the UE may determine which logical channels to place data and how much data to place per logical channel based on the configuration given by the LCC and rules specified by the protocol.
In LTE, the UE performs Logical channel prioritization (Logical channel prioritization) according to 3 steps. In the 5G standard, before the 3 steps are performed, a process of selecting logical channels (logical channels) is also added, that is, the UE selects a logical channel satisfying the transmission condition according to some scheduling configurations in the uplink grant indication.
If there is a parameter configuration (Numerology) indicated by the uplink grant, that is, a Subcarrier Spacing Index (Subcarrier Spacing Index) and a PUSCH transmission Duration (PUSCH transmission Duration), which satisfy the parameter configuration of the high priority service, that is, an Allowed SCS-List (Allowed SCS-List) and a maximum PUSCH Duration (Max PUSCH-Duration), it is possible to satisfy the parameter configuration of the low priority service. The high priority service may be, for example, URLLC service, and the low priority service may be, for example, eMBB service.
Then according to the current protocol, for the resource indicated by this UL grant, these URLLCLCHs and eMBB LCHs that satisfy the condition will participate in Logical Channel optimization (LCP) together, form MAC PDU and perform uplink transmission.
There is only one MAC PDU but there are multiple logical channels to multiplex, which requires that each logical channel be assigned a priority. The data for the highest priority logical channel is preferably contained in the MAC PDU, followed by the data for the next highest priority logical channel, and so on, until the assigned MAC PDU is full or there is no more data to send. The Priority of each Logical Channel is determined by a Priority field of a Logical Channel configuration (Logical Channel configuration), and the smaller the value, the higher the Priority.
However, this allocation scheme may cause the high-priority logical channels to always occupy the radio resources allocated to the UE by the base station, thereby causing the low-priority logical channels to be "starved". To avoid this, the LTE introduces the concept of Prioritized Bit Rate (PBR), i.e. before allocating resources to logical channels, the data Rate of each logical channel is configured, so as to provide minimum data Rate guarantee for each logical channel, and avoid that logical channels with low priority are "starved". Specifically, the minimum data Rate guarantee may be determined by a Prioritized Bit Rate (PBR) field of a logical channel configuration.
Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a data uploading method in the prior art.
The MAC layer implements MAC multiplexing using an algorithm similar to token bucket (token bucket). The basic idea of the algorithm is to determine whether to transmit data of a certain logical channel based on whether there are tokens in the token bucket and how many tokens, and to control the amount of data of the logical channel assembled in the MAC PDU.
The Bucket Size Duration (BSD) determines the "depth" of the token Bucket. It, together with PBR, determines the maximum capacity of the token bucket PBR x BSD. The maximum capacity of the token bucket limits the amount of data that can be suspended (pending), i.e., buffered in a buffer, for each logical channel.
Among the three logical channels (logical channel A, logical channel B and logical channel C), the UE maintains a variable B for each logical channeljThe variable indicates the number of tokens currently available in the token bucket, and each token corresponds to 1Byte of data. B isjIt is initialized to 0 at the time of logical channel establishment, and PBR × TTI is added every Transmission Time Interval (TTI) (if the designated PRB is kBps8, the PRB is 8kBps, i.e. token bucket is injected with 8kBps × 1ms ═ 8Byte token every TTI). The value of Bj cannot exceed the maximum capacity PBR × BSD of the bucket (for example BSD 500ms, maximum capacity 8kBps × 500ms 4k Byte).
When there is newly transmitted data, the UE performs Logical channel prioritization (Logical channel prioritization) according to the following steps:
step 1-for all Bj>The logical channels of 0 are packed according to the descending order of priority, and the radio resources allocated to each logical channel can only meet the requirement of PBR. When the PBR of a certain logical channel is configured to be infinite ("infinity"), a logical channel with a lower priority than the logical channel is considered only when the resources of the logical channel are satisfied.
Step 2: b isjMinus the size of all MAC SDUs that logical channel j multiplexes into MAC PDU in step 1. In one embodiment, for each Radio Link Control (RLC) Service Data Unit (SDU) transmitted for logical channel j, B is comparedjWhether greater than 0. If B is presentjIf the value is greater than 0, the SDU is added into the MACPDU. Then B is mixedjMinus the size T of the SDUSDUAnd determines whether the PBR requirements are met. Repeating the steps until BjLess than 0, or the PBR requirement is met, then the next logical channel is processed.
And step 3: if the first two steps are finished and the uplink wireless resource is left, B is not consideredjThe remaining resources are assigned to the respective logical channels according to logical channel priorities. The logical channel with low priority can be served only when the data of all the logical channels with high priority are sent and the uplink radio resource allocated by the uplink authorization indication is not exhausted. I.e. when the UE maximizes data transmission for the logical channel of high priority.
As shown in fig. 1, the priority of the logical channel a is greater than that of the logical channel B, the priority of the logical channel B is greater than that of the logical channel C, the amount of data transmitted in the logical channel a is D1, PBR is P1, the amount of data transmitted in the logical channel B is D2, PBR is P2, the amount of data transmitted in the logical channel C is D3, and PBR is P3.
It can be determined from the foregoing steps that, in the uplink data, the PBR of the logical channel a, that is, the data 101, is allocated first, then the PBR of the logical channel B, that is, the data 111, is allocated, then the PBR of the logical channel C, that is, the data 121, is allocated, and after the execution is completed, a part of the uplink radio resources is left, then a part of the data amount D1 of the logical channel a is allocated except for the P1.
The inventor of the present invention has found through research that if the uplink radio resource is small, it is possible to transmit only a part of high priority traffic data and a part of low priority traffic data. That is, the block of resources is scheduled for high priority traffic (e.g., URLLC), but a portion of low priority traffic (e.g., eMBB) data is transmitted if the high priority traffic data is not completely transmitted. Then, the remaining high-priority service data in the buffer needs to wait until the next uplink transmission resource arrives for transmission, which further causes the transmission delay of the data packet of the high-priority service, and if the transmission delay is serious, the transmission delay will also be out of order due to timeout.
In the embodiment of the invention, when the UE starts to combine the data to be uploaded at this time, all the data of the first priority service can be sent when the data can be sent by judging whether the data of the first priority service to be sent can be sent completely during the uploading at this time; when the transmission cannot be finished, determining whether to add a first priority service BSR at least according to whether a triggered BSR exists, and uploading data of a low priority service first when the data of a high priority service is not uploaded completely in the prior art; further, compared with the prior art that the network side needs to estimate how many resources the UE needs to upload the data of the first priority service, and then sends the uplink authorization indication to the UE, which is inaccurate and wastes uplink resources, by adopting the scheme of the embodiment of the present invention, the UE can actively judge and report the upload data amount required by the first priority service, thereby contributing to improving the upload accuracy, reducing the upload delay of the first priority service, and improving the utilization rate of transmission resources.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 2, fig. 2 is a flowchart of a data uploading method in an embodiment of the present invention. The data uploading method may include steps S21 to S24:
step S21: determining whether the data of the first priority service can be uploaded or not according to the received uplink authorization indication;
step S22: if the data of the first priority service can be uploaded, determining the uplink transmission data volume according to the uplink authorization indication when the data to be uploaded at this time is combined, and judging whether the data of the first priority service to be transmitted can be transmitted completely at the uploading at this time;
step S23: if the data of the first priority service to be sent cannot be sent completely during the uploading, determining whether to add a first priority service BSR to the data to be uploaded at this time at least according to whether a triggered BSR exists, wherein the first priority service BSR is used for indicating the data of the first priority service to be sent after the uploading;
step S24: and sending the data to be uploaded.
The priority of the first priority service is higher than or equal to a preset priority, the data to be uploaded does not contain data of a second priority service, at least contains a part of the data of the first priority service to be transmitted, and the priority of the second priority service is lower than that of the first priority service.
In a specific implementation of step S21, the UE side may determine whether the data of the first priority service can be uploaded according to the received uplink grant indication, and if the data of the high priority service cannot be uploaded, may upload the data of the low priority service.
Specifically, according to the parameter configuration (Numerology), that is, the subcarrier spacing Index (subcarrier spacing Index) and the PUSCH transmission Duration (PUSCH transmission Duration), the parameter configuration for the high-priority service, that is, the Allowed SCS-List (Allowed SCS-List) and the maximum PUSCH Duration (Max-Duration) may be satisfied, and then the parameter configuration for the low-priority service may be satisfied, and then the parameter configuration for other LCHs (e.g., some lower-priority LCHs, such as eMBB LCHs) may also be satisfied.
It should be noted that the step of determining, by the UE side, whether to upload the data of the first priority service may be performed when receiving the uplink grant indication, or may be performed when starting to combine the data.
In step S22, if the data of the first priority service can be uploaded, it may be determined whether the data of the first priority service to be sent can be sent after the uploading this time.
Specifically, if the data of the first priority service can be uploaded, when the data to be uploaded at this time is started to be combined, determining the uplink transmission data volume according to the uplink authorization indication, and judging whether the data of the first priority service to be transmitted can be transmitted at this time;
in a specific implementation, when the data to be uploaded at this time is combined, the uplink transmission data amount is determined according to the uplink authorization indication. The uplink transmission data amount may be obtained by subtracting a data amount of data that must be transmitted from a total uplink radio resource amount in the uplink grant indication, where the total uplink radio resource amount may be determined according to the time-frequency resource indicated in the uplink grant indication.
Specifically, the uplink radio resource in the uplink grant indication may be determined by the UE side according to the time-frequency domain resource indicated in the uplink grant indication.
For a plurality of logical channels, the channel priorities of the logical channels are different according to the information importance degree, and have the following relative priorities from high to low, and the data which must be transmitted can comprise the data to be transmitted corresponding to the first four levels. That is, if there are the first four levels of data to be transmitted, the data must be allocated to the data to be uploaded this time as the data that must be transmitted.
Level 1: a MAC control element (MAC control element) for a Cell Radio Network temporary identifier (C-RNTI) or data (C-RNTI MAC CE or data from UL-CCCH) from an uplink common control channel (UL-CCCH);
level 2: a MAC control element (Configured Grant configuration MAC ce) for confirming configuration;
level 3: a MAC control element (MAC CE for BSR) for Buffer Status Reports (BSR) other than padding BSR;
level 4: a MAC control element (Single Entry PHR MAC center) for a Single input Power Headroom (Single Entry PHR) or a Multiple input Power Headroom (Multiple Entry PHR).
Further, level 5 may be data from an arbitrary Logical Channel (except data from UL-CCCH) in addition to data of UL-CCCH, and the high priority traffic data and the low priority traffic data may correspond to level 5. More specifically, the high priority traffic (e.g., URLLC traffic) may correspond to one or several higher priority logical channels, and the low priority traffic (e.g., eMBB traffic) may correspond to one or several lower priority logical channels.
It should be noted that the data of the first priority service to be sent is used to indicate the data amount of the first priority service remaining after each upload, that is, the data of the first priority service to be sent is dynamically changed.
Further, the data of the first priority service may be uploaded for multiple times, and the uplink grant indication is received from the network side before each upload. In some cases, the data of the first priority service may also be uploaded only once, or may not be completely transmitted, specifically, taking the high priority service as the URLLC service as an example, because the URLLC service is bursty, there is a possibility that the volume of the URLLC data in the buffer is small, the data is transmitted once, and no data comes next, so only a single upload is performed; or the partial overtime failure which is not transmitted at this time is directly discarded, and the transmission is not performed again next time, so that the transmission is not completely performed.
In the specific implementation of step S23, if the data of the first priority service to be sent cannot be sent completely during the current uploading, that is, the uplink transmission data volume determined according to the uplink authorization indication and the high priority service data in the buffer cannot be sent completely, only the high priority service data may be sent.
Specifically, the uplink transmission data amount may be set to z, that is, the remaining transmittable data amount is assumed to be z except the data amount indicated in the uplink grant indication minus the data amount of the data that must be transmitted; the data of the first priority service to be sent may be set to x.
And when z is smaller than x, determining whether to add a first priority service BSR to the data to be uploaded at the time at least according to whether the triggered BSR exists.
Specifically, the triggered BSR may include a Regular (Regular) BSR or a Periodic (Periodic) BSR.
In the prior art, when starting to combine the data to be uploaded at this time, the UE may determine whether to send a Regular BSR or a Periodic BSR at this time of uploading.
It should be noted that the Regular BSR or the Periodic BSR belongs to the aforementioned data that must be transmitted, and according to the existing protocol, the Regular BSR or the Periodic BSR is packed into the current MAC PDU in preference to the data in the buffer, so that when there is a triggered BSR, z does not contain the data volume of the triggered BSR.
Referring to fig. 3, fig. 3 is a flowchart of an embodiment of step S23 in fig. 2. The step of determining whether to add the first priority service BSR to the current data to be uploaded according to at least whether the triggered BSR exists may include step S31 and step S32, which are described below.
In step S31, if there is a triggered BSR, the first priority service BSR is not added to the current data to be uploaded.
In step S32, if there is no triggered BSR, add the first priority service BSR to the current data to be uploaded.
In a specific implementation, when there is no triggered BSR, a part of high-priority service data and a first priority service BSR are transmitted by using an uplink transmission data volume z, where the first priority service BSR is only used to indicate a data volume of the high-priority service data remaining in a buffer, that is, to indicate data of the first priority service to be transmitted.
It should be noted that if there is no triggered BSR, then according to the existing protocol, no existing other type BSR, such as padding BSR, is allocated. Specifically, because the data part is not completely transmitted and the priority of the data is higher than that of the padding BSR, the existing type of BSR is not packaged into the data to be uploaded this time, that is, the first priority service BSR may be added into the data to be uploaded this time. The first priority service BSR is configured to indicate data of the first priority service to be sent after the current upload.
In the embodiment of the present invention, only when there is no triggered BSR, the first priority service BSR is added to the data to be uploaded this time, which is helpful to avoid transmission resources occupied by sending too many BSRs.
Referring to fig. 4, fig. 4 is a flowchart of another specific embodiment of step S23 in fig. 2. The step of determining whether to add the first priority service BSR to the current data to be uploaded according to at least whether the triggered BSR exists may include steps S41 to S43, which are described below.
In step S41, if there is a triggered BSR, the first priority service BSR is not added to the current data to be uploaded.
In step S42, if there is no triggered BSR and the difference between the data volume of the first priority service to be sent and the uplink transmission data volume is greater than or equal to a preset data volume threshold, adding the first priority service BSR to the current data to be uploaded.
In step S43, if there is no triggered BSR and the difference between the data volume of the first priority service to be sent and the uplink transmission data volume is smaller than a preset data volume threshold, the first priority service BSR is not added to the current data to be uploaded.
In specific implementation, when there is no triggered BSR and x-z ≧ Q, a part of high-priority service data and first-priority service BSR may be transmitted using uplink transmission data volume z. Specifically, the UE may determine that it is difficult to finish uploading the high-priority service data in a short period, and at this time, add the first priority service BSR to the data to be uploaded this time, which is helpful for the UE to inform the network side of the need and the amount of the high-priority service data in advance through the first priority service BSR. And Q is a preset data volume threshold value.
Further, when the triggered BSR exists or x-z is less than Q, the first priority service BSR is not added to the current data to be uploaded, that is, only uplink transmission data amount z is used to transmit a part of high priority service data, which is beneficial to transmitting the high priority service data as soon as possible.
In the embodiment of the present invention, only when there is no triggered BSR and a difference between the data amount of the data of the first priority service to be sent and the uplink transmission data amount is greater than or equal to a preset data amount threshold, the first priority service BSR is added to the data to be uploaded this time, which is helpful to further avoid that transmission resources are occupied by sending too many BSRs.
Referring to fig. 5, fig. 5 is a flowchart of another embodiment of step S23 in fig. 2. The step of determining whether to add the first priority service BSR to the current data to be uploaded according to at least whether the triggered BSR exists may include step S51 and step S52, which are described below.
In step S51, if there is a triggered BSR, the first priority service BSR is not added to the current data to be uploaded.
In step S52, if there is no triggered BSR and the difference between the data amount of the data packet whose waiting time delay is greater than or equal to the preset time delay threshold and the uplink transmission data amount in the to-be-transmitted data of the first priority service is greater than or equal to the preset data amount threshold, adding the BSR of the first priority service to the to-be-uploaded data.
In a specific implementation, the data of the first priority service to be sent includes a plurality of data packets, each data packet has a waiting delay, and when there is no triggered BSR and the data volume of a data packet with a long waiting delay in the data of the first priority service to be sent is very large, a part of high priority service data and the first priority service BSR may be transmitted by using an uplink transmission data volume z. Specifically, the UE may determine that it is difficult to finish uploading the high-priority service data in a short period, and at this time, add the first priority service BSR to the data to be uploaded this time, which is helpful for the UE to inform the network side of the need and the amount of the high-priority service data in advance through the first priority service BSR.
Further, when the triggered BSR exists or the data volume of the data packet with longer waiting time delay in the data of the first priority service to be transmitted is smaller, the first priority service BSR is not added to the data to be uploaded this time, that is, only the uplink transmission data volume z is used to transmit a part of high priority service data, which is beneficial to transmitting the high priority service data as soon as possible.
In the embodiment of the present invention, only when there is no triggered BSR and a difference between a data amount of a data packet whose waiting time delay is greater than or equal to a preset time delay threshold and the uplink transmission data amount in the to-be-transmitted data of the first priority service is greater than or equal to a preset data amount threshold, the first priority service BSR is added to the to-be-uploaded data, which is helpful to further avoid transmission resources occupied by sending excessive BSRs.
With reference to fig. 2, in a specific implementation of step S24, the UE sends the current data to be uploaded to the network side.
Specifically, at the time domain starting point of the resource indicated in the uplink authorization indication, the UE starts to upload the data to be uploaded this time.
In the embodiment of the invention, when the UE starts to combine the data to be uploaded at this time, all the data of the first priority service can be sent when the data can be sent by judging whether the data of the first priority service to be sent can be sent completely during the uploading at this time; when the transmission cannot be finished, determining whether to add a first priority service BSR at least according to whether a triggered BSR exists, and uploading data of a low priority service first when the data of a high priority service is not uploaded completely in the prior art; further, compared with the prior art that the network side needs to estimate how many resources the UE needs to upload the data of the first priority service, and then sends the uplink authorization indication to the UE, which is inaccurate and wastes uplink resources, by adopting the scheme of the embodiment of the present invention, the UE can actively judge and report the upload data amount required by the first priority service, thereby contributing to improving the upload accuracy, reducing the upload delay of the first priority service, and improving the utilization rate of transmission resources.
It can be understood that, in the data uploading method shown in fig. 2, if the data of the first priority service to be sent cannot be sent completely during the current uploading, the data of the second priority service is not uploaded during the current uploading, only the data of the first priority service may be uploaded, only the data of the first priority service and the data that needs to be transmitted may also be uploaded, and only the data of the first priority service, the data that needs to be transmitted, and the BSR of the first priority service may also be uploaded.
Further, the data uploading method may further include: and if the data of the first priority service to be sent can be sent completely during the current uploading, taking the data of the first priority service to be sent as at least one part of the data to be uploaded.
Specifically, if the data of the first priority service to be sent can be sent completely during the current uploading, the data of a second priority service, such as eMBB service data, can be uploaded by using the remaining uplink radio resources in addition to the uploading of the data of the first priority service to be sent. Wherein the second priority traffic has a lower priority than the first priority traffic.
In the embodiment of the present invention, if the data of the first priority service to be sent can be sent completely during the current uploading, the data of the first priority service to be sent is used as at least a part of the data to be uploaded, and the data of the second priority service can be uploaded by using the remaining uplink wireless resources, which is favorable for improving the utilization rate of resource transmission.
