It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning unless explicitly defined in this disclosure.

[0030] The embodiments of the present disclosure provide a method for determining a data transmission timing, which can be applied to any electronic device having a data link layer in a wireless communication network system, and the electronic device can be any type of terminal (UE) or any type of network device. For example, it can be applied to user terminals, base stations, and core network elements that perform data transmission.

[0031] Figure 1 The figure shows a flow chart of a method for determining a data transmission timing sequence. The data transmission timing sequence determination process mainly includes:

[0032] Step 101, obtaining the number of data packets corresponding to each data processing process in the data link layer.

[0033] In some embodiments, each data processing process includes an uplink data processing process and a downlink data processing process, wherein the uplink data processing process includes: an uplink pre-packaging process, an uplink confirmation data release process and an uplink authorization packaging process; the downlink data processing process includes a downlink delivery process.

[0034] Among them, the downlink data processing process also includes the unpacking process of the downlink transmission block (TB). The time required for the result process of the downlink transmission block cannot be estimated. Through on-demand segmentation during real-time processing, the reasonable progress of each data processing process is guaranteed.

[0035] Step 102: Determine the estimated duration corresponding to each data processing process according to the number of data packets corresponding to each data processing process.

[0036] In some embodiments, determining the estimated duration corresponding to each data processing process based on the number of data packets corresponding to each data processing process includes: obtaining a mapping relationship between the number of data packets corresponding to each data processing process and the processing time; and determining the estimated duration corresponding to each data processing process based on the mapping relationship.

[0037] Among them, the mapping relationship between the number of data packets and the processing time corresponding to each data processing process is obtained by pre-measurement. By using the mapping relationship between the number of data packets and the processing time obtained in advance, when the number of data packets corresponding to the data processing process is obtained, the estimated time required for the data processing process can be predicted before the data processing process begins. For the process whose time consumption cannot be estimated, it can be split as needed during the real-time processing process, so as to reasonably plan each data processing process.

[0038] In some embodiments, the process of obtaining the mapping relationship between the number of data packets and the processing time in any data processing process includes: obtaining the actual processing time corresponding to each number of packets in the data processing process by statistics; performing linear fitting on the actual processing time corresponding to each number of packets to obtain the mapping relationship between the number of packets and the processing time in the data processing process, wherein the mapping relationship is used to reflect the relationship between the rate of the data processing process, the number of packets, the time increment and the total time of the data processing process. The mapping relationship between the number of data packets and the processing time is determined for each data processing process according to the obtaining process.

[0039] Exemplarily, taking UE as an example, linear fitting is performed by obtaining the relationship between the number of data packets and the processing time of multiple groups, and the relationship between the number of data packets and the processing time of each data processing process is statistically analyzed. The relationship can be a linear expression, specifically including: the mapping relationship expression of the uplink pre-packaging process is: T1=V1*N1+t1; the mapping relationship expression of the uplink authorization packetization process is: T2=V2*N2+t2; the mapping relationship expression of the uplink confirmation data release process is: T3=V3*N3+t3; in the unpacking process of the downlink transmission block, the number of data packets is unknown and cannot be estimated in advance, and is divided according to the real-time processing process; the mapping relationship expression of the downlink delivery process is: T4=V4*N4+t4.

[0040] Among them, T1, T2, T3 and T4 each represent the total time consumed by the corresponding data processing process; V1, V2, V3 and V4 each represent the rate of the corresponding data processing process, and the rate of a type of data processing process in the same system usually does not change; N1, N2, N3 and N4 each represent the number of data packets in the corresponding data processing process; t1, t2, t3 and t4 each represent the corresponding time increment, and the time increment in the mapping relationship of the corresponding data processing process after linear fitting is a fixed value.

[0041] Step 103: Determine the transmission timing of the data link layer according to the estimated duration corresponding to each data processing process and the transmission priority of each data processing process.

[0042] In some embodiments, the transmission priority of each data processing process within a transmission time interval (TTI) includes: at the moment when the uplink authorization arrives, the uplink authorization packet assembly process has the highest priority; in the first time period before the moment when the uplink authorization arrives, the uplink pre-packaging process has the highest priority; in the second time period after the moment when the uplink authorization arrives, the downlink delivery process has the highest priority.

[0043] The unpacking process of the downlink transmission block can be interspersed in the first time period and the second time period. If the unpacking cannot be completed in the first time period, the unpacking of the unfinished part will continue in the second time period. If the unpacking cannot be completed in the second time period, the unpacking will continue in the next transmission time interval, and so on. In the first time period, the priority of the unpacking process of the downlink transmission block is lower than the uplink pre-packaging process; the uplink authorization packaging process is given priority when the uplink authorization arrives; in the second time period, because the downlink delivery process depends on the downlink delivery data obtained by the unpacking process of the downlink transmission block, the processing time of the downlink delivery process is estimated according to the real-time processing progress of the unpacking process of the downlink transmission block.

[0044] Exemplarily, the duration of a TTI is 0.5 ms.

[0045] In some embodiments, the uplink grant arrival time is fixed in each transmission time interval, so as to compare the estimated completion time of each processing process with the uplink grant arrival time.

[0046] Exemplarily, the uplink grant arrival time is set at a fixed position within the transmission time interval as required. Once a device sets the uplink grant arrival time, each transmission time interval is executed according to the same uplink grant arrival time.

[0047] In some embodiments, the transmission timing corresponding to each data processing process is determined according to the estimated duration corresponding to each data processing process and the transmission priority of each data processing process, including: for any transmission time interval, the transmission timing corresponding to each data processing process is determined according to the following process: in a first time period before the arrival of the uplink authorization, the transmission timing within the first time period is determined according to the estimated duration corresponding to each of the uplink pre-packaging cache data, the uplink confirmation data and the downlink delivery data and the duration of the first time period; when the uplink authorization moment arrives, the uplink authorization packet assembly process is completed in priority according to the estimated duration corresponding to the uplink authorization packet assembly processing process; the transmission timing within the second time period is determined according to the data process that is not completed in the first time period.

[0048] Exemplarily, in the first time period, while giving priority to ensuring that the uplink pre-packaging process is completed, if a downlink transmission block is received, the downlink transmission block is unpacked, and the transmission timing is determined according to the real-time processing of the unpacking process of the downlink transmission block before the uplink authorization moment; if the unpacking process of the downlink transmission block is completed and there is uplink confirmation data, the uplink confirmation data release process is prioritized; if the unpacking process of the downlink transmission block is not completed, the unfinished part is cached and waits for the second time period or the next transmission time interval to be processed. If the release process of the uplink confirmation data is completed, the delivery process of the downlink delivery data continues, and the part of the downlink delivery data that cannot be completed in the first time period waits for the second time period or the next transmission time interval to be processed. After the uplink authorization package processing process is completed in the second time period, the process that cannot be completed in the first time period is continued, which includes the unpacking process of the downlink transmission block, the delivery process of the downlink delivery data after the unpacking process of the downlink transmission block is completed, and the release process of the uplink confirmation data after the delivery process of the downlink delivery data is completed.

[0049] In some embodiments, in a first time period before the uplink authorization arrives, the transmission timing in the first time period is determined according to the estimated duration corresponding to the uplink pre-packet cache data, the uplink confirmation data and the downlink delivery data and the duration of the first time period, including: in the first time period, according to the estimated duration corresponding to the uplink pre-packet cache data, judging whether the estimated time when the processing of the uplink pre-packet cache data is completed exceeds the uplink authorization time, if so, processing part of the uplink pre-packet cache data before reaching the uplink authorization time, otherwise, completing the processing of the uplink pre-packet cache data; after completing the processing of the uplink pre-packet cache data, in the case of uplink confirmation data, judging according to The estimated time corresponding to the release of the uplink confirmation data is used to determine whether the moment when the uplink confirmation data is released exceeds the uplink authorization moment. If so, part of the uplink confirmation data is released before the uplink authorization moment is reached, and the unreleased uplink confirmation data is saved in the uplink confirmation data cache. Otherwise, the release process of the uplink confirmation data is completed. After completing the release process of the uplink confirmation data, in the case of the existence of downlink delivery data, according to the estimated time corresponding to the delivery of the downlink delivery data, determine whether the moment when the downlink delivery data is delivered exceeds the uplink authorization moment. If so, part of the data corresponding to the downlink delivery data is delivered before the uplink authorization moment is reached. Otherwise, the delivery process of the downlink delivery data is completed.

[0050] Among them, before the uplink authorization moment arrives, the transmission sequence is arranged in order according to the estimated time consumed for uplink pre-packaging cache data, the estimated time consumed for uplink confirmation data, and the estimated time consumed for downlink delivery data. If the transmission time of any item is too long and is expected to exceed the uplink authorization arrival moment, the item is split to ensure that the uplink authorization packaging process is handled in time when the uplink authorization moment arrives, and to ensure that the uplink authorization packaging process can be completed in time.

[0051] In some embodiments, it also includes: after completing the processing process of the uplink pre-packaging cache data, receiving a downlink transmission block and performing an unpacking process on the downlink transmission block; when the unpacking process of the downlink transmission block is completed before the uplink authorization moment, and when the uplink confirmation data exists in the downlink data obtained by unpacking the downlink transmission block or in the downlink data cache, executing the step of judging whether the moment when the uplink confirmation data is released exceeds the uplink authorization moment according to the estimated duration corresponding to the release of the uplink confirmation data; when the unpacking process of the downlink transmission block is not completed before the uplink authorization moment, when the uplink authorization moment arrives, obtaining unpacked data, saving the unpacked data in the downlink transmission block to the downlink data cache, and executing the process according to the uncompleted data in the first time period to determine the transmission timing in the second time period.

[0052] Among them, for the unpacking process of the downlink transmission block whose estimated time is unpredictable, it is divided on demand during real-time processing to ensure the orderly progress of each data processing process and avoid affecting the timely progress of other data processing processes due to the long unpacking process of the downlink transmission block.

[0053] In some embodiments, the determination of the transmission timing in the second time period according to the data process that is not completed in the first time period includes: after completing the uplink authorization packetization process, unpacking the unpacked data and saving the unpacked downlink data to the downlink data cache; in the case where all the packets are unpacked before the arrival of the next transmission time interval, judging whether the time when the delivery is completed exceeds the arrival time of the next transmission time interval according to the estimated time duration corresponding to the downlink delivery data in the downlink data cache, and if so, delivering part of the downlink delivery data in the downlink data cache before the arrival of the next transmission time interval, otherwise, completing the delivery process of all the downlink delivery data in the downlink data cache; after completing the delivery process of all the downlink delivery data in the downlink data cache, in the case where there is unreleased uplink confirmation data, judging according to the The estimated time corresponding to the release process of the unreleased uplink confirmation data is used to judge whether the moment of release completion exceeds the arrival time of the next transmission time interval. If so, part of the data in the unreleased uplink confirmation data is released before the arrival time of the next transmission time interval. Otherwise, the release process of all the uplink confirmation data is completed. After completing the release process of all the uplink confirmation data, in the case that there is unprocessed pre-package cache data, according to the estimated time corresponding to the processing process of the unprocessed pre-package cache data, it is judged whether the moment of processing completion exceeds the arrival time of the next transmission time interval. If so, part of the data of the unprocessed pre-package cache data is processed before the arrival time of the next transmission time interval. Otherwise, the processing process of the unprocessed pre-package cache data is completed.

[0054] Among them, after the uplink authorization packaging process is completed in the second time period, the unpacking process of the unfinished downlink transmission, the downlink delivery process, and the release process of the uplink confirmation data are processed in sequence, and the processing process that cannot be completed in the second time period is divided and left for the next transmission time interval to continue processing, so as to ensure that each processing process is carried out in an orderly manner in the second time period, and to ensure that the current processing process is terminated in time when the next transmission time interval arrives, so as to ensure that the next transmission time interval The related processes are executed in sequence according to priority in time.

[0055] The following is an example of a method for determining the data transmission timing.

[0071] Step 211, determine whether the time when all downlink delivery is completed is less than the arrival time of the next TTI, if not, execute step 212; if yes, execute step 213;

[0075] Step 215: Process the uplink pre-packetized data that can be processed before the next TTI arrives according to T1=V1*N1+t1, and end the process.

[0076] Figure 3 Another part of the data transmission timing determination process is shown, which includes:

[0077] Step 2021, split the uplink pre-packaging buffer data, put the uplink pre-packaging buffer data that cannot be completed after the splitting back into the pre-packaging buffer, and perform the uplink pre-packaging process on the remaining part; receive the downlink TB, cache the TB; calculate the estimated time of uplink authorization packaging according to T2=V2*N2+t2, perform the uplink authorization packaging process, and then perform the downlink TB unpacking process, and execute step 301;

[0090] Among them, the uplink confirmation data release process needs to be before the delivery process of the downlink delivery data obtained by downlink unpacking and after the pre-packaging process, so as to avoid the problem that the uplink data has been confirmed to occupy the memory and cause the uplink authorization packaging failure.

[0091] Among them, in a TTI, when all downlink delivery data cannot be delivered, while the remaining part is cached, a warning is issued that the downlink data cache has not been processed in time, and then the next TTI is processed.

[0092] Among them, in a TTI, when the uplink confirmation data cannot be fully released, when releasing part of the uplink confirmation data, part of the cache cannot be released and a warning is given that there is an uplink confirmation data cache that has not been processed, and the next TTI is processed before that.

[0093] The data link layer data transmission timing determination method provided by the embodiment of the present disclosure estimates and determines the expected duration corresponding to each data processing process according to the number of data packets corresponding to each data processing process in the data link layer, and determines the transmission timing of the data link layer according to the expected duration corresponding to each data processing process and the transmission priority of each data processing process. Therefore, by estimating the time consumption of each data processing process, the data transmission timing can be reasonably planned, and the normal transmission of each data processing process can be guaranteed according to the priority, so as to avoid abnormal situations caused by a certain processing process taking too long, thereby improving the system transmission performance and system stability.

[0094] Compared with the prior art, the data processing process is not planned in advance, which may lead to missed authorization packet assembly resulting in reduced uplink rate, priority processing of uplink pre-packet assembly resulting in unprocessed downlink data interruption, and failure to promptly process confirmed data release resulting in uplink packet assembly abnormalities. A data transmission timing planning method based on an estimation method is provided in the embodiments of the present invention, which can effectively reduce the above-mentioned abnormal problems, and plans the data processing process of the data link layer in real time according to the importance by estimating the data processing process time, and plans in advance for situations with long processing time to improve performance and provide early warning, thereby improving the stability and controllability of data transmission.

[0095] The step division of the above various methods is only for clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the protection scope of this disclosure. Adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the protection scope of this disclosure.
