All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As shown in fig. 1 and 2, the present application provides a communication data resource pool allocation method, which includes the following steps:
step 100, separating a first SA pool, a second SA pool and a data pool by using a time division multiplexing mode to form a D2D resource pool scheme, wherein the first SA pool is an SA pool for periodically transmitting data allocation resources, and the second SA pool is an SA pool for burst transmitting data allocation resources; step 200, in the D2D resource pool scheme, a channel competition process is integrated to construct a resource transmission model;
step 300, sequentially obtaining the data transmission type and the state of the intermediate channel, so as to directly transmit burst transmission data in an idle state or select an area in a data pool correspondingly allocated to a first SA pool based on periodic transmission data, and perform data transmission in the selected resource pool area;
step 400, judging the data transmission type based on the resource pool configuration signaling sent by the first terminal, counting the situations of periodic transmission and burst transmission, and calculating the occurrence probability of the periodic transmission and the burst transmission in the current period;

In the application, the intermediate channel is checked in each period, the burst type transmission data is directly transmitted in the idle state of the intermediate channel, channel competition is carried out when the data to be sent is the periodic transmission data, and the low time delay requirement of the burst type transmission can be met by directly transmitting the burst type transmission data.
In addition, the occurrence probability of the periodic transmission and the burst transmission in the current period is calculated by counting the conditions of the periodic transmission and the burst transmission, and the resource transmission model parameters are adjusted according to the time proportion of the periodic transmission and the burst transmission, so that the data transmission waiting time is reduced as much as possible in the current data transmission application scene, and the data transmission speed is improved.
In the application, the first SA pool, the second SA pool and the data pool are separated in a time division multiplexing mode to form a D2D resource pool scheme, the resource pool can be regarded as one SA pool and one data pool, the SA pool is divided into two types, one is the SA pool for periodically transmitting data to allocate resources, the other is the SA pool for burst transmitting data to allocate resources, wherein the periodic SA pool can allocate resources in the data pool in the next period, and the burst SA pool can allocate resources in the data pool in the current period.
As shown in fig. 3, in step 200, in the D2D resource pool scheme, a channel contention process is incorporated to construct a resource transmission model, including the following steps;
presetting the channel competition period to be 0.5s;
dividing a resource pool consisting of a plurality of periodic blocks into periodic transmission time, burst transmission time, SA pool time and channel competition time in a time division multiplexing mode;
presetting data scheduling in SA pool time;
channel competition of periodically transmitting data is preset in channel competition time to obtain a subsequent corresponding occupied frequency band and the occupied frequency band is mapped into a data pool;
channel detection is preset in an initial preset time period of each period block, burst transmission data is transmitted when an intermediate channel is idle, and the next period block is waited to repeat the operation when the channel is busy;
and presetting the period type transmission time to perform data transmission in the corresponding data pool.
The above steps are mainly described for the main process of step 200, and the resource pool is divided into four time portions: the periodic transmission time, the burst transmission time, the SA pool time and the channel competition time are set in different time parts to perform corresponding data transmission work, and the data collision can be avoided through the setting.
Wherein, in SA pool time, data scheduling is carried out; the channel competition mainly aims at channel competition of the periodic transmission data in the channel competition time, and the frequency band occupied by different periodic transmission data in the data pool can be obtained in the channel competition process (the channel competition process is also the selection of different periodic transmission data to the resource area in the data pool); carrying out data transmission on the periodic transmission data mapped into the data pool in the periodic transmission time; and transmitting the burst transmission data in the data pool in the burst transmission time.
Wherein the periodic transmission time, the burst transmission time, the SA pool time, and the channel contention time all occupy at least one periodic block.
Each period block corresponds to a small period, the occupied time of each period block is 1ms, that is, the occupied time of each period block can be 1ms, other reasonable values such as 0.5ms and the like can be adopted in the practical application process, the percentage of the occupied time of the whole period block in the preset time period is a%, wherein a takes 25, and if the occupied time of the small period is 1ms, the initial channel detection time is 0.25ms.
And channel detection is carried out in an initial preset time period of each period block, burst type transmission data is transmitted when the middle channel is idle, the next period block is waited to repeat the operation when the channel is busy, that is, the channel detection is started at the initial time of each small period, and the burst type transmission data is transmitted when the channel is idle, so that the probability of burst type transmission data is carried out in each small period, and the time delay of burst type transmission data transmission is greatly reduced.
In the application, the periodic transmission time is adjacent to the burst transmission time, and the time ratio of the periodic transmission time to the burst transmission time is 1:1 in the initial condition.
Because the probability of burst type transmission data transmission is smaller in the actual application process, the time ratio of the periodic type transmission time to the burst type transmission time can be 4:1 or 3:1, and the like, and the data transmission rate can be specifically adjusted according to different data transmission conditions.
Step 300, sequentially obtaining the data transmission type and the status of the intermediate channel, so as to directly transmit burst transmission data in an idle state or select an area in a data pool correspondingly allocated to the first SA pool based on periodic transmission data, and perform data transmission in the selected resource pool area, including:
acquiring and checking a data transmission type;
detecting the state of an intermediate channel under burst transmission data, and directly transmitting when idle;
detecting whether the channel competition time exists under the period type transmission data, if so, selecting an area in a data pool correspondingly allocated to the first SA pool, and if not, returning;
and detecting whether the transmission time is in the periodic transmission time, if so, transmitting data in the selected resource pool area, and if not, returning.
The above steps mainly describe that when data is received, whether burst type transmission data or periodic type transmission data is checked first, and when intermediate channel state idle is detected when burst type transmission data is received, direct transmission is performed, which also includes two cases, if burst type transmission time is now in, data transmission can be performed directly, if burst type transmission time is not in, whether channel detection can be performed when channel detection is in a preset time period is detected, idle data transmission can be performed when channel detection is in a preset time period, and if burst type transmission data can be re-detected when burst type transmission time is not in a preset time period, that is, data transmission can be performed when burst type transmission time and preset time period are both in the burst type transmission time.
And when the received data is periodically transmitted data, detecting whether the data is in channel competition time, if so, performing channel competition (selecting resources in a data pool), then checking whether the data is in SA pool time, if so, performing data scheduling (scheduling the data to the resources selected in the channel competition), then checking whether the data is in periodic transmission time, and if so, transmitting the data scheduled to the data pool.
In step 400, determining a data transmission type based on a resource pool configuration signaling sent by a first terminal, counting the situations of periodic transmission and burst transmission, and calculating the occurrence probability of the periodic transmission and the burst transmission in the current period, including:
counting the conditions of periodic transmission and burst transmission and drawing a proportion graph;
dividing regional interval points with the proportion difference exceeding a threshold value, and taking the average value of occurrence probability proportion from the interval point to the current time point as a prediction ratio;
and calculating the occurrence probability of the periodic transmission and the burst transmission in the current period according to the prediction ratio.
In the above embodiment, after the proportion graph is drawn, the interval points of the area where the proportion difference exceeds the threshold value need to be divided, where the proportion difference refers to the difference between the proportion average value of a certain period and another period, the threshold value may be preset, for example, as shown in fig. 4, assuming that the proportion graph of the case of the periodic transmission and the burst transmission is shown in the figure, the threshold value of the period of 5 hours is 3, the proportion average value is about 2.6,5-22 hours in the period of 0-5 hours, the proportion average value is about 2.9, the difference is less than 3, the proportion average value is about 2.6 in the period of 0-6 hours, the proportion average value is 2.9 in the period of 6-22 hours, the difference is less than 3, and the case where the difference is not greater than 3 is not obtained is obtained, therefore, in this case, the average value of all the previous proportions is taken as the predicted ratio, assuming that 15/28 is taken as the occurrence probability of the periodic transmission, and 13/28 is taken as the occurrence probability of the burst transmission.
Taking fig. 5 as an example, assuming that the proportion graphs of the case of the periodic transmission and the burst transmission are shown, the same calculation is performed, the proportion difference between the 0-10 hour period and the 10-22 hour period is larger than 3, the proportion difference between the 0-11 hour period and the 11-22 hour period is also larger than 3, the proportion average value of the 10-22 hour period or the 11-22 hour period after the current time is 22 hours can be used as a prediction ratio, and the proportion value of the 10 hour time point deviates from the proportion data between 11-22 hours, so that the proportion value of the 10-22 hour period is discharged, and the proportion value of the 11-22 hour period is used as the prediction ratio.
In step 500, adjusting the time ratio of the periodic transmission and the burst transmission based on the occurrence probability to adjust the resource transmission model parameters includes:
taking the ratio of occurrence probability as the time ratio of periodic transmission and burst transmission;
the occurrence probability value of burst transmission is adjusted as a%.
Taking the predicted ratio of 15:13 as an example in the above case, taking 15/28 as the occurrence probability of periodic transmission, taking 13/28 as the occurrence probability of burst transmission, and taking the ratio of the occurrence probability, namely 15:13 as the time ratio of periodic transmission and burst transmission.
Meanwhile, a% is set to be the occurrence probability value of burst type transmission, namely 13/28, so that the time occupied by the preset time period is adjusted, and the setting can further reduce the time delay of burst type transmission.
The time occupied by the preset time period is not changed under the normal condition in the actual application process, but the time occupied by the preset time period is adjusted under the condition that the burst type transmission occurs more, so that the burst type transmission congestion is avoided.
The application also discloses the following embodiment to avoid the situation that the second terminal does not receive the data sent by the first terminal, concretely, the method comprises the following steps that the second terminal receives the data sent by the first terminal, the first terminal receives the feedback information of the second terminal to confirm the data receiving situation of the first terminal, and the first terminal marks the data as burst transmission data to carry out the second direct transmission under the feedback abnormal situation, and the method comprises the following steps:

the first terminal regulates and controls to resend under the condition that feedback information is not received or the feedback information is abnormal;
and marking the current transmission data as burst transmission data, and judging the state of the intermediate channel to directly transmit.
The first terminal automatically adjusts the percentage a% of the time of occupying the whole period block to be na% under the condition that feedback information is not received or the feedback information is not received, and resets a% after the current data transmission is implemented;
wherein n is 2.
In the above embodiment, the retransmission is regulated and controlled under the condition that the second terminal does not receive the feedback information or the feedback information is abnormal, and the transmission data is marked as burst transmission data so as to be convenient for quickly performing the second transmission, and at the same time, the occupation time of the preset time period is increased, and the time delay of the current transmission data is reduced.
