Background
LTE-V2X research topic of 3GPP SA1 in 2015, LTE-V2X was then a research hotspot in 3GPP (Third Generation Partnership project) groups, where the core research hotspot includes V2V (Vehicle to Vehicle) related technologies. With the continuous innovation and application of the V2V technology, the demand of the wireless communication system for spectrum resources is also increasing, so that the wireless resources are in a tight trend.
In the 3GPP Release14 standard, a scheduling manner and a resource allocation scheme in the V2V service are studied, and in the related art, the scheme mainly includes a FIFO (First Input First Output) or a resource allocation scheme for randomly selecting a receiving end. The resource allocation scheme of the FIFO refers to that receiving ends are selected in a queue of the receiving ends of each transmitting end according to the time sequence of the arrival queue, and the receiving end which arrives at the queue first has the highest priority of being served. The resource allocation scheme for randomly selecting the receiving ends refers to that one receiving end is randomly selected from a queue of the receiving ends of each transmitting end, and the probability of each receiving end in the queue being selected is the same.
The two schemes are simple to implement, and the system complexity is relatively low, but in consideration of the situation that the radio spectrum resources are relatively tense, the two schemes cannot fully and effectively utilize the system resources, which may result in an unsatisfactory PRR (Packet Reception Ratio) at the receiving end, thereby resulting in a decrease in system performance and a poor user service quality.

The technical solution of the present invention is further explained with reference to fig. 4 to 6.
In this embodiment, a data sending end and a data receiving end that support V2X service, where the data sending end performs radio spectrum resource allocation based on the path loss of the data receiving end, and in the resource allocation process, in combination with the geographic environment information of the data receiving end, the system resources are more fully and effectively utilized, and the user experience is improved, as shown in fig. 4, the management method of radio spectrum resources in this embodiment includes:

And step 408, configuring a priority for each data receiving end according to the size of the path loss value, wherein the smaller the path loss value is, the higher the priority is.
And step 410, allocating wireless spectrum resources to the data receiving end according to the priority, and constructing scheduling information.
And step 414, counting the PRR result according to the fed back ACK or NACK information.
The active set (i.e., the receipt receiving end set) in step 402 refers to a data receiving end group corresponding to each data sending end, each data receiving end traverses all the data sending ends, estimates the path loss between them, sorts them, selects the data sending end corresponding to the link with the smallest path loss, after all the data receiving ends complete traversal, each data sending end can obtain a reference data receiving end set, and then the data sending end traverses all the data receiving ends in the set and excludes the data sending ends with longer distance according to the effective communication range distance control, thereby finally determining the active set of each data sending end.
Specifically, as shown in fig. 5, VUE1 in the figure indicates a data transmitting end that needs to transmit data, VUE2 in an ellipse, VUE3 indicates a data receiving end that meets the requirement of a communication distance within a target distance, and VUE4 indicates a data receiving end that does not meet the requirement of the communication distance, and there is no need to provide service for it.
In this embodiment, in the communication process, each data receiving end in the active set reports its current geographical location information, the data sending end calculates a path loss value from the data sending end to the data receiving end according to the geographical location information reported by the data receiving end and the current channel model, and the data receiving end with smaller path loss has higher priority and preferentially performs radio spectrum resource allocation. Compared with random distribution, the method reasonably utilizes resources and can improve the success rate of receiving the data packet.
Specific calculation modes of the WINNWE B1 channel model commonly used in V2V (where a scene includes LOS (Line of Sight) and NLOS (Not Line of Sight) are combined with fig. 6 and table 1, BS denotes a base station, MS denotes a terminal, and d shown in fig. 61And d2Corresponding to d in the calculation formula PL of the path loss value under the NLOS scene in Table 11And d2) The description is given for the sake of example:
TABLE 1
The following description is given with reference to tables 2 and 3 for system-level simulation results under the resource allocation mode randomly selected by the ue and the resource allocation mode based on the path loss, and the statistical result is the reception success rate (PRR):
TABLE 2
TABLE 3
In the process of counting results, the results obtained by each simulation are different in consideration of randomness introduced in the simulation. The influence of randomness can be eliminated as much as possible by multiple times of simulation and averaging. According to the current simulation experience, when the average result obtained by running N times of simulation is smaller than the average result obtained by running N +1 times of simulation, the simulation is considered to be stable. In this study, it is basically satisfactory to take N to 9 or 10. The simulation results are shown in Table 3 (statistical results are mean PRR, 1000 slots/group).
From simulation results, it is easy to see that the receiving success rate (PRR) obtained by the data sending end based on the path loss resource allocation scheme is obviously higher than that of the randomly selected resource allocation scheme, and the user experience is improved.
