Detailed Description
As previously described, when the UE has data to send to the network, the amount of data is reported to the network via the BSR. In the prior art, according to the protocol specification, the case where BSR can be triggered is as follows:
1. when a Logical Channel of a Logical Channel Group (LCG) has new uplink data to arrive; and the priority of the logical channel is higher than that of any logical channel with uplink data in any LCG, or other logical channels in the LCG where the logical channel is located have no uplink data.
2. The remaining space in the uplink allocated resources is sufficient to load the BSR.
Specifically, when a previous batch of data to be sent is uploaded, for example, when the current uploaded batch of data is the last batch of uploaded data, if the remaining space in the uplink allocated resources is sufficient to install the BSR, the user terminal may send the BSR together during the current upload to notify the network side of the data amount of the next batch of data to be sent.
3. When the retransmission Time (RetxBSR-Time) expires, at least one logical channel in a certain LCG has uplink data.
Specifically, if the retxsrb-Time timer expires, the user terminal will regenerate a BSR.
4. The cycle time (PeriodicBSR-Timer) expires.
Specifically, if the PeriodicBSR-Timer times out, the user terminal will periodically generate a BSR regardless of whether it needs to upload data.
The inventor of the present invention finds, through research, that in the prior art, BSR can be transmitted according to the data amount of a subsequent batch of data to be transmitted only when a previous batch of data to be transmitted is completely transmitted or is about to be completely transmitted, however, a time interval of multiple TTIs often exists between the transmission of BSR and the reception of uplink grant on a network side, which causes a break in the process of transmitting uplink data by UE.
In the embodiment of the invention, a first BSR is sent to a network side, the first BSR comprises the data volume of a previous batch of data to be sent, the previous batch of data to be sent is uploaded for multiple times, and an uplink authorization indication aiming at the first BSR is received from the network side before each uploading; when an uplink authorization instruction is received from the network side every time, judging whether the unsent part in the previous batch of data to be sent can be uploaded within a preset time length or not according to the uplink transmission data volume in the uplink authorization instruction; and if the unsent part can be uploaded within the preset time length, a second BSR is sent to the network side during the uploading, and the second BSR comprises the sum of the data volume of the next batch of data to be sent and the data volume of the unsent part. By adopting the scheme, when the uplink authorization indication is received from the network side every time, whether the part which is not transmitted in the previous data to be transmitted can be completely uploaded within the preset time length is judged, if the part can be completely uploaded, the previous data to be transmitted is indicated to be completely transmitted, at the moment, the second BSR is transmitted in advance, and the subsequent data which needs to be uploaded is reported to the network side so as to apply for authorization as early as possible. Compared with the prior art that the second BSR at the network side is reported after the previous batch of data to be sent is uploaded, by adopting the scheme of the embodiment of the invention, the early application authorization can be realized by sending the second BSR in advance, which is beneficial to continuously uploading data. Further, compared with the prior art that the network side needs to estimate whether uplink data exists in the UE, and further provides resources for the UE to send a BSR, which is inaccurate and wastes uplink resources, the scheme of the embodiment of the present invention can actively determine and report the required data volume to be sent by the UE in time, thereby improving accuracy and contributing to saving uplink 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. 1, fig. 1 is a flowchart of a method for reporting a BSR according to an embodiment of the present invention. The method for reporting BSR may include steps S11 to S13:
step S11: sending a first BSR to a network side, wherein the first BSR comprises the data volume of a previous batch of data to be sent, the previous batch of data to be sent is uploaded for multiple times, and an uplink authorization indication aiming at the first BSR is received from the network side before each uploading;
step S12: when an uplink authorization instruction is received from the network side every time, judging whether the unsent part in the previous batch of data to be sent can be uploaded within a preset time length or not according to the uplink transmission data volume in the uplink authorization instruction;
step S13: and if the unsent part can be uploaded within the preset time length, a second BSR is sent to the network side during the uploading, and the second BSR comprises the sum of the data volume of the next batch of data to be sent and the data volume of the unsent part.
In the specific implementation of step S11, the UE reports the first BSR to the network side to apply for resources, and by sending the BSR, the network side can know the amount of data that the UE needs to send, and further the network side can allocate resources in a targeted manner.
Specifically, the first BSR includes a data amount of a previous batch of data to be transmitted, and the previous batch of data to be transmitted can be uploaded once and can be uploaded for multiple times according to a resource size allocated by a network side.
When the previous batch of data to be transmitted needs to be uploaded for multiple times, an uplink authorization indication for the first BSR is received from the network side before each time of uploading, where the uplink authorization indication includes an uplink transmission data volume, that is, the size of the data volume that can be uploaded this time. And the UE can upload data according to the uplink authorization indication.
In the specific implementation of step S12, each time the uplink authorization indication is received from the network side, it is not directly started to upload data as in the prior art, but it is necessary to determine whether the untransmitted portion of the previous data to be transmitted can be uploaded within a preset time period.
The preset duration can be regarded as a time advance variable for sending uplink data, and when the unsent part is about to be uploaded, the preset duration can be set to send a BSR to the network side in advance in time to apply for resources of next batch of data to be sent.
In a specific implementation manner of the embodiment of the present invention, the preset duration may be self-defined by each UE, and may be set to 2 TTIs, for example.
In another specific implementation manner of the embodiment of the present invention, Radio Resource Control (RRC) is configured when configuring a Medium Access Control (MAC) layer. This approach may employ display configuration specific values, or may employ default configurations. Wherein the default value may be set to 2 TTIs, for example.
Preferably, the preset duration may be set to be greater than or equal to a duration between sending the first BSR and receiving the uplink grant indication for the first time. Therefore, the current network state of the network side can be judged to be smooth or congested according to the time length from the time when the first BSR is sent to the time when the uplink authorization indication is received for the first time, that is, compared with a user-defined value or a default value, the current network state of the network side can be more accurately embodied, and the uploading waiting time can be favorably reduced.
Preferably, the preset duration may be set to be equal to a duration from after the first BSR is sent to when the uplink grant indication is received for the first time, which is beneficial to avoiding that the second BSR is uploaded too early, so that a new data demand occurs after the second BSR is uploaded, and the data volume of the next batch of data to be sent in the second BSR does not meet the actual situation, and the data accuracy in the second BSR is improved by adopting the preferred scheme.
Referring to fig. 2, fig. 2 is a flowchart of an embodiment of step S12 in fig. 1. The step of determining whether the unsent part of the previous data to be transmitted can be uploaded within the preset time period according to the uplink transmission data amount in the uplink grant indication may include steps S21 to S23, and the following steps are described.
In step S21, an average value of N uplink transmission data amounts in the uplink grant indications of the previous N times is determined, where N is a positive integer.
Specifically, the average value of the first N known uplink transmission data amounts may be calculated and used as a pre-judgment result of the subsequent uplink transmission data amounts, and then whether the untransmitted part of the previous batch of data to be transmitted can be uploaded within a preset time period is estimated according to the pre-judgment result.
It should be noted that the previous uplink grant indication N times should be an uplink grant indication adjacent to this time, so that when the average value of the uplink transmission data amount is analyzed each time, the latest data N times, that is, the latest state of the network side, can be used to analyze, which is helpful for improving the accuracy of prejudging the subsequent uplink transmission data amount, and thus more accurately judging whether the unsent part in the previous data to be sent can be uploaded within the preset time length.
Referring to fig. 3, fig. 3 is a flowchart of an embodiment of step S21 in fig. 2. The step of determining the average value of the N uplink transmission data amounts in the previous N uplink grant indications may include steps S31 to S32, which are described below.
In step S31, N uplink transmission data amounts in the uplink grant indications of the previous N times are determined.
Specifically, the N uplink transmission data amounts in the uplink grant indications of the previous N times may be determined through calculation according to the uplink transmission data amounts included in the uplink grant indications of the previous N times.
In a specific implementation manner of the embodiment of the present invention, the N may be customized for each UE.
It can be understood that the value of N should not be too small, otherwise it is difficult to reflect the network status of the network side in the past period; the value of N should not be too large, otherwise the amount and complexity of computation is increased and it is not significant to compute the network state too long ago. Preferably, N may be set to 3.
In another embodiment of the present invention, the RRC may configure the MAC together. This approach may employ display configuration specific values, or may employ default configurations. Wherein the default value may be set to 3, for example.
In step S32, weighted average data of the N uplink transmission data amounts is calculated as an average value of the N uplink transmission data amounts.
Specifically, a higher weight may be set for the uplink transmission data amount in the uplink grant instruction more adjacent to this time, and a lower weight may be set for the uplink transmission data amount in the uplink grant instruction farther away from this time, so that the network state at the current network side is more reflected when determining the average value of the uplink transmission data amounts.
It should be noted that, in another specific implementation manner of the embodiment of the present invention, an arithmetic mean value of the N uplink transmission data amounts may also be directly calculated to serve as the mean value of the N uplink transmission data amounts.
With reference to fig. 2, in step S22, the total amount of uplink transmission data within a preset time period is estimated according to the average value of the N uplink transmission data amounts.
Specifically, the total amount of uplink transmission data within a preset time period may be estimated according to the average value of the N uplink transmission data amounts by using the following formula:
BSR_Q＝BSR_T×BSR_AVG；
the BSR _ Q is configured to represent a total uplink transmission data amount within a preset time duration, the BSR _ T is configured to represent the preset time duration, and the BSR _ AVG is configured to represent a mean value of the N uplink transmission data amounts.
More specifically, the BSR _ T is used to represent the preset duration, which may be a preset number of TTIs, for example; the BSR _ AVG is used to represent an average value of the N uplink transmission data amounts, for example, an average data transmission amount in each TTI; the bsrq may be used to represent a transmission amount of data that may be transmitted within a duration of a preset number of TTIs, i.e., a predicted value of a total amount of uplink transmission data within a preset duration.
In step S23, if the data amount of the unsent portion is less than or equal to the uplink transmission data amount, or the data amount of the unsent portion is less than or equal to the total uplink transmission data amount in the preset time period, it is determined that the unsent portion can be uploaded within the preset time period.
Specifically, if the data amount of the unsent part is less than or equal to the uplink transmission data amount, it may be determined that the uplink transmission data amount indicated this time may directly finish sending the data of the unsent part; if the data volume of the unsent part is less than or equal to the total uplink transmission data volume in the preset time length, it can be judged that the unsent part can finish uploading in the preset time length according to the average value of the N uplink transmission data volumes in the previous N uplink authorization indications and the data of the unsent part can be estimated in the preset time length.
With reference to fig. 1, in a specific implementation of step S13, if the unsent part of the previous data to be transmitted can be uploaded within a preset time period, the second BSR is transmitted to the network side during the current uploading.
It should be noted that, since the second BSR needs to occupy Resource Block (RB) resources, when uploading this time, the sum of the uplink transmission data and the second BSR is the uplink transmission data amount in the uplink grant indication received this time. In a specific implementation, the second BSR may have a Header (Header) and BSR data, so that the network side identifies the second BSR in uplink transmission data.
The second BSR may include a sum of a data amount of a next batch of data to be transmitted and a data amount of the untransmitted portion, and is recorded as BSR margin (BSR _ V), for example.
Specifically, the BSR margin may be used to indicate a data amount to be sent, the sent data amount may be subtracted from the BSR margin after the UE uplink transmits data each time, and the data amount of the next batch of data to be sent may be added to the BSR margin after the UE determines the data amount of the next batch of data to be sent. It can be understood that, when the BSR margin is less than or equal to 0, it indicates that the data to be transmitted corresponding to the reported BSR has been transmitted.
In the embodiment of the present invention, each time an uplink authorization indication is received from the network side, it is determined whether an unsent part of the previous data to be transmitted can be uploaded within a preset time period, if the unsent part of the previous data to be transmitted can be uploaded within the preset time period, it indicates that the previous data to be transmitted is to be completed, at this time, a second BSR is transmitted in advance, and subsequent data to be uploaded is reported to the network side, so as to apply for authorization as early as possible. Compared with the prior art that the second BSR at the network side is reported after the previous batch of data to be sent is uploaded, by adopting the scheme of the embodiment of the invention, the early application authorization can be realized by sending the second BSR in advance, which is beneficial to continuously uploading data. Further, compared with the prior art that the network side needs to estimate whether uplink data exists in the UE, and further provides resources for the UE to send a BSR, which is inaccurate and wastes uplink resources, the scheme of the embodiment of the present invention can actively determine and report the required data volume to be sent by the UE in time, thereby improving accuracy and contributing to saving uplink resources.
Referring to fig. 4, fig. 4 is a flowchart of another method for reporting BSR according to an embodiment of the present invention. The other method for reporting the BSR may include steps S41 to S48, which are described below.
In step S41, the first BSR is transmitted to the network side.
In step S42, an uplink grant instruction is received.
In step S43, the data amount of the untransmitted portion in the previous data to be transmitted is determined.
In step S44, it is determined whether the data size of the untransmitted portion is equal to or less than the uplink transmission data size, or equal to or less than BSR _ Q; when the determination result is yes, step S46 may be performed; otherwise, step S45 may be performed.
Specifically, the following formula may be adopted to determine BSR _ Q — BSR _ T × BSR _ AVG.
When receiving an uplink grant indication for the first time, the value of BSR _ AVG may be 0; furthermore, each time an uplink grant indication is received, the average value of N uplink transmission data amounts in the previous N uplink grant indications may be re-determined to be the value of BSR _ AVG.
In step S45, the uplink data is transmitted.
Specifically, each time an uplink authorization instruction is received from the network side, whether unsent parts in the previous data to be sent can be uploaded within a preset time length is judged according to the uplink transmission data volume in the uplink authorization instruction; and if the unsent part cannot be uploaded within the preset time length, only sending uplink data during the uploading.
In step S46, the sum BSR _ V of the data amount of the next data to be transmitted and the data amount of the untransmitted portion is determined.
In step S47, a second BSR is determined.
In step S48, the uplink data is transmitted, and the second BSR is transmitted to the network side.
In the specific implementation, please refer to the description of steps S1 to 3 for further details regarding steps S41 to S48, which are not repeated herein.
