技术领域Technical field
本发明涉及通信数据技术领域,具体涉及通讯数据资源池分配方法、计算机装置和存储介质。The present invention relates to the field of communication data technology, and specifically to a communication data resource pool allocation method, a computer device and a storage medium.
背景技术Background technique
终端到终端(DevicetoDevice,D2D)通信是支持移动设备和移动设备之间使用专用空中接口技术直接数据通信的技术,与传统的蜂窝通信技术最大的不同在于,终端与终端之间的通信不再需要基站的中转直接就可以进行通信,D2D技术是采用广播的形式进行数据的传输,采用调度分配(SA)+数据(Data)的机制,SA是用来指示从发送端发出的数据的状态信息,数据发送指令及发送的数据冗杂,通过资源池的分配能够解决资源碰撞的问题。Device-to-Device (D2D) communication is a technology that supports direct data communication between mobile devices using dedicated air interface technology. The biggest difference from traditional cellular communication technology is that communication between terminals no longer requires Communication can be carried out directly through the relay of the base station. D2D technology uses the form of broadcast to transmit data and adopts the scheduling allocation (SA) + data (Data) mechanism. SA is used to indicate the status information of the data sent from the sending end. The data sending instructions and the data sent are complex, and the problem of resource collision can be solved through the allocation of resource pools.
资源池包括SA池和data池,通常将SA池分为两类,一类是为Periodic traffic(周期型传输)数据分配资源的SA池,一类是为Event—triggered traffic(突发型传输)数据分配资源的SA池,并用时分复用区分,这两种SA池都是周期性的,Periodictraffic的SA池的周期是Event—triggered traffic的SA池的几倍,它们调度的data池是共同的,周期型的SA池能够分配下一个周期内data池中的资源,事件突发型的SA池能够对当前周期的data池中资源进行分配。Resource pools include SA pools and data pools. SA pools are usually divided into two categories. One is the SA pool that allocates resources for Periodic traffic (periodic transmission) data, and the other is the SA pool for Event-triggered traffic (burst transmission). The SA pool of data allocation resources is distinguished by time division multiplexing. Both SA pools are periodic. The period of the SA pool of Periodicraffic is several times that of the SA pool of Event-triggered traffic. Their scheduled data pools are the same. Yes, the periodic SA pool can allocate resources in the data pool in the next cycle, and the event burst SA pool can allocate resources in the data pool in the current cycle.
突发型传输和周期型传输均是周期性进行的,数据传输过程存在不同的应用场景,存在突发数据传输情况较多的应用场景,突发型传输和周期型传输周期无法进行适应性调整,对应不同类型的数据传输过程需要等待前一时段结束之后再进行,突发型传输数据传输时间要求较高,周期性进行的数据传输工作无法满足突发型传输的低时延要求。Both burst transmission and periodic transmission are performed periodically. There are different application scenarios in the data transmission process. There are application scenarios with a lot of burst data transmission. The periods of burst transmission and periodic transmission cannot be adaptively adjusted. , corresponding to different types of data transmission processes, you need to wait for the end of the previous period before proceeding. Burst transmission has higher data transmission time requirements, and periodic data transmission cannot meet the low latency requirements of burst transmission.

如图1和图2所示,本发明提供了通讯数据资源池分配方法,包括以下步骤:As shown in Figures 1 and 2, the present invention provides a communication data resource pool allocation method, which includes the following steps:
步骤100,将第一SA池、第二SA池和data池用时分复用形式分开,以形成D2D资源池方案,其中第一SA池为周期型传输数据分配资源的SA池,第二SA池为突发型传输数据分配资源的SA池;步骤200,在D2D资源池方案中,融入信道竞争过程构建资源传输模型;Step 100: Separate the first SA pool, the second SA pool and the data pool using time division multiplexing to form a D2D resource pool solution, where the first SA pool is an SA pool that allocates resources for periodic transmission data, and the second SA pool SA pool that allocates resources for burst transmission data; step 200, in the D2D resource pool solution, integrate the channel competition process to build a resource transmission model;
步骤300,依次获取数据传输类型和中间信道的状态,以在空闲状态对突发型传输数据进行直接传输或者基于周期型传输数据选择第一SA池对应分配的data池中的区域,并在选择的资源池区域中进行数据发送;Step 300: Obtain the data transmission type and the status of the intermediate channel in order to directly transmit the burst transmission data in the idle state or select the area in the data pool corresponding to the first SA pool based on the periodic transmission data, and select Send data in the resource pool area;
步骤400,基于第一终端发送的资源池配置信令判断数据传输类型,统计周期型传输和突发型传输的情况,计算当前时段内周期型传输和突发型传输的发生概率;Step 400: Determine the data transmission type based on the resource pool configuration signaling sent by the first terminal, collect statistics on periodic transmission and burst transmission, and calculate the occurrence probability of periodic transmission and burst transmission within the current period;

The first terminal receives feedback information from the second terminal to confirm the data reception status of the first terminal. In the case of abnormal feedback, the first terminal marks the data as burst transmission. The data is transferred directly for the second time.
本发明中,每个周期内均对中间信道进行检查,在中间信道空闲状态对突发型传输数据进行直接传输,在待发数据为周期型传输数据时进行信道竞争,对突发型传输数据进行直接传输的方式能够满足突发型传输的低时延要求。In the present invention, the intermediate channel is checked in each cycle, burst transmission data is directly transmitted in the idle state of the intermediate channel, channel competition is performed when the data to be sent is periodic transmission data, and burst transmission data is The direct transmission method can meet the low latency requirements of burst transmission.
另外,通过统计周期型传输和突发型传输的情况计算当前时段内周期型传输和突发型传输的发生概率,并且根据发生概率调整周期型传输和突发型传输的时间比例调整资源传输模型参数,使得在当前数据传输应用场景下尽可能减少数据传输等待时间,提高数据传输速度。In addition, the probability of occurrence of periodic transmission and burst transmission in the current period is calculated by counting periodic transmission and burst transmission, and the time ratio of periodic transmission and burst transmission is adjusted according to the occurrence probability to adjust the resource transmission model Parameters to minimize data transmission waiting time and improve data transmission speed in the current data transmission application scenario.
本发明中将第一SA池、第二SA池和data池用时分复用形式分开,以形成D2D资源池方案,资源池可以看做是一个SA池、一个data池,SA池分为两类,一个是周期型传输数据分配资源的SA池,另一个是突发型传输数据分配资源的SA池,其中周期型的SA池可以分配下一个周期内data池内的资源,突发型的SA池能够分配当前周期内data池内的资源。In the present invention, the first SA pool, the second SA pool and the data pool are separated using time division multiplexing to form a D2D resource pool solution. The resource pool can be regarded as an SA pool and a data pool. The SA pool is divided into two categories. , one is an SA pool that allocates resources for periodic transmission data, and the other is an SA pool that allocates resources for burst transmission data. The periodic SA pool can allocate resources in the data pool in the next cycle, and the burst type SA pool Able to allocate resources in the data pool in the current cycle.
如图3所示,步骤200中,在D2D资源池方案中,融入信道竞争过程构建资源传输模型,包括以下步骤;As shown in Figure 3, in step 200, in the D2D resource pool solution, the channel competition process is integrated into the resource transmission model, which includes the following steps;
预设信道竞争周期为0.5s;The default channel competition period is 0.5s;
将由若干个周期块组成的资源池以时分复用形式分为周期型传输时间、突发型传输时间、SA池时间和信道竞争时间;The resource pool composed of several periodic blocks is divided into periodic transmission time, burst transmission time, SA pool time and channel competition time in the form of time division multiplexing;
预设在SA池时间内,进行数据的调度;Data is scheduled within the SA pool time by default;
预设在信道竞争时间内进行周期型传输数据的信道竞争,以得出后续相应的占用频段并将占用频段映射到data池中;It is preset to perform channel competition for periodic transmission of data within the channel competition time to obtain the subsequent corresponding occupied frequency band and map the occupied frequency band to the data pool;
预设在每个周期块的初始预设时间段内进行信道检测,中间信道空闲时进行突发型传输数据的传输,信道忙时等待下一周期块重复上述操作;It is preset to perform channel detection within the initial preset time period of each periodic block. When the intermediate channel is idle, burst transmission data is transmitted. When the channel is busy, wait for the next periodic block to repeat the above operation;
预设在周期型传输时间在相应data池中进行数据传输。Data transmission is preset in the corresponding data pool at the periodic transmission time.
上述步骤主要为步骤200的主要过程描述,将资源池分为四个时间部分:周期型传输时间、突发型传输时间、SA池时间和信道竞争时间,并设置在不同的时间部分内进行对应的数据传输工作,这样的设置能够避免数据碰撞。The above steps mainly describe the main process of step 200. The resource pool is divided into four time parts: periodic transmission time, burst transmission time, SA pool time and channel competition time, and are set to correspond in different time parts. Data transmission work, this setting can avoid data collision.
其中,在SA池时间内,进行数据调度;在信道竞争时间内主要是针对周期型传输数据的信道竞争,在信道竞争的过程中能够得出不同的周期型传输数据在data池中所占用的频段(信道竞争过程也是不同的周期型传输数据对data池内资源区域的选择);在周期型传输时间内对上述映射到data池中的周期型传输数据进行数据传输;在突发型传输时间内对data池内的突发型传输数据进行数据传输。Among them, data scheduling is performed during the SA pool time; during the channel competition time, the channel competition is mainly for periodic transmission data. During the channel competition process, it can be obtained that different periodic transmission data occupy the data pool. Frequency band (the channel competition process is also the selection of resource areas in the data pool for different periodic transmission data); within the periodic transmission time, the periodic transmission data mapped to the data pool is transmitted; within the burst transmission time Perform data transmission for burst transmission data in the data pool.
其中,周期型传输时间、突发型传输时间、SA池时间和信道竞争时间均占据至少一个周期块。Among them, periodic transmission time, burst transmission time, SA pool time and channel competition time all occupy at least one periodic block.
每个周期块对应一个小周期,每个周期块占据的时间为1ms,也就是说小周期的时间可以是1ms,在实际应用过程中也可以是0.5ms等其他合理数值,预设时间段占据周期块整体的时间的百分比为a%,其中a取25,如果小周期占据时间为1ms,则初始进行信道检测的时间为0.25ms。Each period block corresponds to a small period, and the time occupied by each period block is 1ms. That is to say, the time of the small period can be 1ms. In actual application, it can also be 0.5ms and other reasonable values. The preset time period occupies The percentage of the entire periodic block time is a%, where a is 25. If the small period occupies 1ms, the initial channel detection time is 0.25ms.
在每个周期块的初始预设时间段内进行信道检测,中间信道空闲时进行突发型传输数据的传输,信道忙时等待下一周期块重复上述操作,也就是说每个小周期的初始时间均开始信道检测,在信道空闲时进行突发型传输数据的传输,这样每个小周期都有进行突发型传输数据的几率,大大降低了突发型传输数据传输的时延。Channel detection is performed within the initial preset time period of each periodic block. When the middle channel is idle, burst transmission data is transmitted. When the channel is busy, wait for the next periodic block to repeat the above operation. That is to say, the initial period of each small period Channel detection is started every time, and burst transmission data is transmitted when the channel is idle. In this way, there is a probability of burst transmission data in every small period, which greatly reduces the delay of burst transmission data.
本发明中,周期型传输时间和突发型传输时间相邻,初始情况下周期型传输时间和突发型传输时间的时间比例为1:1。In the present invention, the periodic transmission time and the burst transmission time are adjacent, and the time ratio between the periodic transmission time and the burst transmission time is 1:1 in the initial situation.
由于实际应用过程中突发型传输数据传输的几率较小,也可以将周期型传输时间和突发型传输时间的时间比例为4:1或者3:1等,具体根据不同的数据传输情况来调整。Since the probability of burst transmission data transmission is small in actual applications, the ratio of periodic transmission time to burst transmission time can also be 4:1 or 3:1, etc., depending on different data transmission situations. Adjustment.
步骤300,依次获取数据传输类型和中间信道的状态,以在空闲状态对突发型传输数据进行直接传输或者基于周期型传输数据选择第一SA池对应分配的data池中的区域,并在选择的资源池区域中进行数据发送,包括:Step 300: Obtain the data transmission type and the status of the intermediate channel in order to directly transmit the burst transmission data in the idle state or select the area in the data pool corresponding to the first SA pool based on the periodic transmission data, and select Data is sent in the resource pool area, including:
获取并检查数据传输类型;Get and check the data transfer type;
在突发型传输数据下检测中间信道状态,空闲时进行直接发送;Detect the intermediate channel status under burst transmission data and send directly when idle;
在周期型传输数据下检测是否处于信道竞争时间,若是则选择第一SA池对应分配的data池中的区域,若否,返回;Detect whether it is in the channel contention time under periodic transmission data. If so, select the area in the data pool allocated corresponding to the first SA pool. If not, return;
检测是否处于周期型传输时间,若是则在选择的资源池区域中进行数据发送,若否,返回。Check whether it is a periodic transmission time. If so, send data in the selected resource pool area. If not, return.
上述步骤主要说明的是,在接收到数据时首先检查是突发型传输数据还是周期型传输数据,在是突发型传输数据的时候检测中间信道状态空闲时进行直接发送,这也包括两种情况,假设现在处于突发型传输时间,可直接进行数据传输,假设现在不处于突发型传输时间,检测当前是否处于预设时间段,如果处于预设时间段则可以进行信道检测,空闲则进行数据传输,如果不处于预设时间段则返回重新检测是否处于突发型传输时间,也就是说,突发型传输数据可以在突发型传输时间和预设时间段两种时间情况下能够进行数据传输。The main description of the above steps is that when receiving data, first check whether it is burst transmission data or periodic transmission data. When the data is burst transmission data, it is detected that the intermediate channel status is idle and sent directly. This also includes two types. situation, assuming that it is now in burst transmission time, data can be transmitted directly. Assuming that it is not in burst transmission time, check whether it is in the preset time period. If it is in the preset time period, channel detection can be performed. If it is idle, Perform data transmission. If it is not in the preset time period, it will return to re-detect whether it is in the burst transmission time. That is to say, burst transmission data can be transmitted in both the burst transmission time and the preset time period. Perform data transfer.
当接收到数据是周期性传输数据时检测是否处于信道竞争时间,若在则进行信道竞争(选择data池中的资源),之后检查是否处于SA池时间,若在则进行数据调度(将数据调度至信道竞争中选择的资源里),之后检查是否处于周期型传输时间,若在则将调度到data池内的数据进行传输。When the received data is periodically transmitted, it is detected whether it is in the channel competition time. If so, channel competition is performed (selecting the resources in the data pool), and then it is checked whether it is in the SA pool time. If so, data scheduling is performed (the data is scheduled). to the resource selected in the channel competition), and then check whether it is a periodic transmission time. If it is, the data in the data pool will be scheduled for transmission.
步骤400中,基于第一终端发送的资源池配置信令判断数据传输类型,统计周期型传输和突发型传输的情况,计算当前时段内周期型传输和突发型传输的发生概率,包括:In step 400, the data transmission type is determined based on the resource pool configuration signaling sent by the first terminal, periodic transmission and burst transmission are counted, and the probability of occurrence of periodic transmission and burst transmission in the current period is calculated, including:
统计周期型传输和突发型传输的情况绘制比例曲线图;Draw a proportional curve chart for statistical periodic transmission and burst transmission;
划分比例差距超出阈值的区域间隔点,将间隔点到当前时间点的发生概率比例平均值作为预测比值;Divide the regional interval points where the proportion gap exceeds the threshold, and use the average occurrence probability ratio from the interval point to the current time point as the predicted ratio;
根据预测比值计算当前时段内周期型传输和突发型传输的发生概率。Calculate the occurrence probability of periodic transmission and burst transmission in the current period based on the prediction ratio.
上述实施例中,绘制比例曲线图之后,需要划分比例差距超出阈值的区域间隔点,其中比例差距指的是某一时段与另一时段的比例平均值的差,阈值可预先设置,以图4为例,假设周期型传输和突发型传输的情况的比例曲线图如图所示,将5小时时段的阈值为3,在0-5小时时段内,比例平均值约为2.6,5-22小时时段内,比例平均值约为2.9,差值小于3,在0-6小时时段内,比例平均值约为2.6,在6-22小时时段内比例平均值为2.9,差值小于3,在每个时间间隔点均做上述计算,未得到差值大于3的情况,因此,此种情况下可将之前所有比例的平均值作为预测比值,假设为15:13,则将15/28作为周期型传输的发生概率,将13/28作为突发型传输的发生概率。In the above embodiment, after drawing the proportion curve, it is necessary to divide the regional intervals where the proportion gap exceeds the threshold. The proportion gap refers to the difference between the average proportion of a certain period and another period. The threshold can be set in advance, as shown in Figure 4 For example, assume that the ratio curve of periodic transmission and burst transmission is as shown in the figure. The threshold of the 5-hour period is 3. In the 0-5 hour period, the average ratio is about 2.6, 5-22 In the hour period, the average ratio is about 2.9, and the difference is less than 3. In the 0-6 hour period, the average ratio is about 2.6. In the 6-22 hour period, the average ratio is 2.9, and the difference is less than 3. The above calculation is done at each time interval point, and no difference is greater than 3. Therefore, in this case, the average of all previous ratios can be used as the predicted ratio. Assuming it is 15:13, then 15/28 is used as the period. For the occurrence probability of burst transmission, 13/28 is taken as the occurrence probability of burst transmission.
以图5为例,假设周期型传输和突发型传输的情况的比例曲线图如图所示,做以上相同的计算,可以计算得出0-10小时时段与10-22小时时段的比例差距大于3,0-11小时时段与11-22小时时段的比例差距也大于3,当前时间处于22小时之后,可以将10-22小时时段或者11-22小时时段的比例平均值作为预测比值,由于10小时时间点的比例数值偏离11-22小时之间比例数据较多,因此,排出10-22小时时段的比例数值,将11-22小时时段的比例数值作为预测比值。Take Figure 5 as an example. Assume that the proportion curve of periodic transmission and burst transmission is as shown in the figure. By doing the same calculation as above, you can calculate the proportion difference between the 0-10 hour period and the 10-22 hour period. is greater than 3, the ratio gap between the 0-11 hour period and the 11-22 hour period is also greater than 3. The current time is after 22 hours, and the average ratio of the 10-22 hour period or the 11-22 hour period can be used as the prediction ratio. Since The proportion value at the 10-hour time point deviates more from the proportion data between 11 and 22 hours. Therefore, the proportion value for the 10-22 hour period is discharged and the proportion value for the 11-22 hour period is used as the predicted ratio.
步骤500中,基于发生概率调整周期型传输和突发型传输的时间比例,以调整资源传输模型参数,包括:In step 500, the time ratio of periodic transmission and burst transmission is adjusted based on the probability of occurrence to adjust resource transmission model parameters, including:
将发生概率的比值作为周期型传输和突发型传输的时间比例;The ratio of occurrence probabilities is used as the time ratio between periodic transmission and burst transmission;
将突发型传输的发生概率值作为a%进行调整。Adjust the occurrence probability value of burst transmission as a%.
以上述案例中预测比值为15:13为例,将15/28作为周期型传输的发生概率,将13/28作为突发型传输的发生概率,将发生概率的比值也就是15:13作为周期型传输和突发型传输的时间比例。Taking the prediction ratio of 15:13 in the above case as an example, 15/28 is used as the occurrence probability of periodic transmission, 13/28 is used as the occurrence probability of burst transmission, and the ratio of the occurrence probabilities is 15:13 as the period. The time ratio between type transfer and burst type transfer.
与此同时,将a%设置为突发型传输的发生概率值也就是13/28,由此对预设时间段所占时间进行调整,这样的设置能够进一步降低突发型传输的时延。At the same time, a% is set to the occurrence probability value of burst transmission, which is 13/28, thereby adjusting the time occupied by the preset time period. This setting can further reduce the delay of burst transmission.
实际应用过程中预设时间段所占时间通常情况下不做改变,但在突发型传输发生情况较多的情况下,要对预设时间段所占时间进行调整以避免突发型传输拥挤。In actual applications, the time occupied by the preset time period is usually unchanged. However, when burst transmission occurs frequently, the time occupied by the preset time period must be adjusted to avoid congestion in burst transmission. .
本发明还公开了以下实施例来避免第二终端未接收到第一终端发送数据的情况,具体如下,第二终端接收第一终端发送的数据,第一终端接收第二终端的反馈信息以确认第一终端的数据接收情况,在反馈异常情况下第一终端将数据标记为突发型传输数据进行第二次的直接传输,包括:The present invention also discloses the following embodiments to avoid the situation where the second terminal does not receive the data sent by the first terminal.

其中,n取2。Among them, n is 2.
