Fig. 2 shows a flowchart of a channel resource scheduling method in an embodiment of the present disclosure, and as shown in fig. 2, the channel resource scheduling method provided in the embodiment of the present disclosure includes the following steps:

s202, obtaining channel state information reported by a first terminal.

It should be noted that the channel state information may be any channel state information reported by the first terminal, and specifically, the channel state information (Channel State Information, CSI) refers to information for describing the current state of the wireless channel. The channel state information contains a number of key parameters such as channel gain, fading, multipath effects, interference, etc. These parameters may be used to describe the quality, reliability, capacity, etc. characteristics of the channel, which are important for the design and optimization of the wireless communication system.

In a multi-terminal communication system, each terminal has its own channel state information. These channel state information can be collected by the terminal device and sent to the network side device by specific signaling. The network side equipment can utilize the channel state information to carry out dynamic resource allocation and scheduling so as to furthest improve the performance and reliability of data transmission in the current transmission environment.

S204, determining the quality index information of the physical resource block PRB to be scheduled according to the channel state information.

The physical resource block (Physical Resource Block, PRB) is a basic unit for channel resource allocation in a communication system. The physical resource block PRB to be scheduled refers to an unallocated physical resource block to be allocated to the first terminal in a channel resource scheduling process. In a communication system, a network side device schedules available channel resources to meet a communication requirement of a first terminal. In order to reasonably utilize the channel resources, the network side device selects an appropriate PRB for allocation according to the requirements of the first terminal and the current network state.

The quality index information of the PRBs to be scheduled may be any index information for evaluating the quality of the PRBs. These indicators may reflect the channel state, interference conditions, and other performance characteristics of the PRBs. The following are some common quality index information:

Channel Gain (Channel Gain): the received strength of the radio signal on the PRB is measured, and a higher channel gain indicates a better signal quality.

Signal-to-Noise Ratio (SNR): representing the ratio of signal to noise, a higher signal to noise ratio represents better signal quality.

Signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR): for measuring the interference level, indicating the signal quality level.

Channel quality indication (Channel Quality Indication, CQI): an indication value reflecting channel quality.

Since the channel state information reported by the first terminal includes a plurality of quality index information, the quality index information of the physical resource block PRB to be scheduled can be determined according to the channel state information. The network side equipment can select proper PRBs to be allocated to the terminal equipment according to the quality index information so as to improve system performance and user experience.

S206, according to the PRB meeting the preset quality index condition, channel resources are scheduled for the first terminal.

It should be noted that, according to the PRB to be scheduled that satisfies the preset quality indicator condition, channel resources may be scheduled for the first terminal. The network side device can select the PRB meeting the preset quality index condition for allocation according to the requirement of the first terminal and the current communication system state.

Specifically, the preset quality index condition may be any set of quality index conditions preset in the channel resource scheduling process, and is used for selecting PRBs meeting a specific quality requirement. The specific values and setting manners of these preset quality index conditions depend on different scenes and network requirements. The network side equipment can be properly adjusted and optimized according to actual conditions and algorithm strategies so as to realize better system performance and user experience.

According to the resource scheduling method provided by the embodiment of the disclosure, PRBs meeting the preset quality index conditions are selected according to the channel state information reported by the first terminal and allocated to the first terminal, so that channel resources are reasonably scheduled for the first terminal, and the communication experience of the first terminal user is optimized.

It should be noted that, in the technical solution of the present disclosure, the acquiring, storing, using, processing, etc. of data all conform to relevant regulations of national laws and regulations, and various types of data such as personal identity data, operation data, behavior data, etc. relevant to individuals, clients, crowds, etc. acquired in the embodiments of the present disclosure have been authorized.

In some embodiments of the present disclosure, the physical resource blocks PRBs to be scheduled comprise: PRBs for multiple sub-band channels. As shown in fig. 3, before the channel resources are scheduled for the first terminal according to PRBs satisfying the preset quality indicator condition, the method further includes the following steps:

S302, obtaining channel quality indication CQI values of each sub-band channel.

The channel quality indicator (Channel Quality Indicator, CQI) is quality index information. The CQI is an indication information measured by the first terminal and fed back to the network side equipment, and the network side equipment can evaluate the channel quality through the CQI value to decide how to allocate limited resources and adopt proper scheduling strategies according to the current channel condition of the first terminal so as to provide better transmission quality and system performance.

S304, judging whether CQI value of each sub-band channel is larger than a preset channel quality indication threshold value.

It should be noted that, to determine whether the CQI value of each sub-band channel is greater than a preset channel quality indication threshold, the preset channel quality indication threshold needs to be determined. The channel quality indication threshold may be set according to specific system requirements and performance requirements, typically determined by network planning and optimization personnel.

The CQI value for each sub-band channel is compared to a preset channel quality indication threshold. If the CQI value is larger than a preset channel quality indication threshold value, the channel quality of the sub-band channel is better; if the CQI value is less than or equal to a preset channel quality indication threshold, it indicates that the channel quality of the sub-band channel may be poor.

And S306, determining PRBs of sub-band channels with CQI values larger than a preset channel quality indication threshold value in each sub-band channel as PRBs meeting preset quality index conditions.

It should be noted that, if the PRB to be scheduled includes PRBs of a plurality of sub-band channels, there may be a plurality of PRBs of sub-band channels whose CQI value is greater than the preset channel quality indication threshold in each sub-band channel. These multiple PRBs satisfying the conditions can be taken into account when performing channel resource scheduling and ensure that they are reasonably allocated to the first terminal to provide better transmission quality and system performance.

According to the method provided by the embodiment of the disclosure, the PRBs meeting the preset channel quality indication threshold are determined through the CQI values of the sub-band channels, and then one or more PRBs meeting the conditions are scheduled to the first terminal, so that better communication quality is provided for the first terminal.

In some embodiments of the present disclosure, the preset channel quality indication threshold is a CQI value of a full band channel.

The CQI value of the full-band channel may be derived from channel state information reported by the first terminal. Judging whether the CQI value of each sub-band channel is larger than a preset channel quality indication threshold value or not, namely judging whether the CQI value of each sub-band channel is larger than the CQI value of the full-band channel or not.

And acquiring the channel state information reported by the first terminal, and acquiring the CQI value of the full-band channel as a preset channel quality indication threshold. And then comparing the CQI value of each sub-band channel, and if the CQI value of the sub-band channel is larger than the CQI value of the full-band channel, determining the corresponding PRB as the PRB meeting the preset quality index condition.

The scheduling method can effectively utilize the channel state information of the full-band channel to schedule the channel resources, takes the PRB with the sub-band channel CQI value larger than the CQI value of the full-band channel as the PRB resource with better quality, and determines the quality judgment standard so as to conveniently and better judge the quality of the PRB.

In some embodiments of the present disclosure, as shown in fig. 4, after determining PRBs of a sub-band channel having a CQI value greater than a preset channel quality indication threshold among the respective sub-band channels as PRBs satisfying a preset quality indicator condition, the method further includes the steps of:

s402, judging whether PRBs meeting the preset quality index conditions are occupied by a second terminal or not, wherein the resource scheduling priority of the second terminal is lower than that of the first terminal.

It should be noted that, the resource scheduling priority of the second terminal is lower than that of the first terminal, which is understood that the first terminal has a higher priority than the second terminal to be scheduled to the required channel resource. In general, the first terminal may be a high priority user terminal or a terminal with special requirements, such as a terminal device of a VIP user. And the second terminal may be a normal user or a terminal device with a lower priority.

By placing the second terminal with the lower resource scheduling priority in the lower resource acquisition priority, the first terminal can be ensured to acquire the required resources preferentially in case of resource conflict. This maintains fairness and efficiency of the communication system and satisfies specific requirements of different terminals.

Whether the PRB satisfying the preset quality index condition is occupied by the second terminal can be understood as whether the PRB resource with good quality is occupied by the second terminal.

And S404, if the PRBs meeting the preset quality index conditions are not occupied by the second terminal, sequencing the PRBs meeting the preset quality index conditions.

It should be noted that, the PRBs satisfying the preset quality index condition may be a plurality of PRBs, where the number of PRBs not occupied by the second terminal may also be a plurality of PRBs, and the plurality of PRBs not occupied by the second terminal and satisfying the preset quality index condition are ordered, where the specific ordering is based on the size of the CQI value, and the PRBs are ordered according to the CQI values of the plurality of PRBs.

S406, according to the sorting result, channel resources are scheduled for the first terminal.

And according to the sequencing result, aiming at the scheduling requirement of the first terminal, scheduling and distributing channel resources for the first terminal.

In the resource scheduling process, an appropriate number of PRBs are selected from the PRBs with better channel quality ranked in front according to the result of the ranking, and allocated to the first terminal. The number of choices may be determined based on actual requirements and scheduling policies. The goal of scheduling channel resources is to enable the first terminal to acquire high quality signals, and to obtain better transmission performance and user experience of the first terminal. By allocating PRBs having a higher CQI value, the first terminal can enjoy resources having higher channel quality.

In some embodiments of the present disclosure, as shown in fig. 5, after determining whether PRBs satisfying a preset quality indicator condition are occupied by a second terminal, the method further includes the steps of:

s502, if the PRB meeting the preset quality index condition is occupied by the second terminal, judging whether the quality index difference value between the first PRB and the second PRB of the second terminal is larger than a preset quality index difference value threshold, wherein the first PRB is the PRB occupied by the second terminal, and the second PRB is the PRB to be scheduled to the second terminal.

It should be noted that, when the PRB satisfying the preset quality index condition is occupied by the second terminal, it means that the PRB with the better quality is already occupied by the second terminal, and according to the method provided by the embodiment of the present disclosure, at this time, the quality index difference between the first PRB and the second PRB of the second terminal will be further determined. If the difference is smaller than a preset quality index difference threshold, PRBs occupied by the second terminal can be scheduled to the first terminal.

It should also be explained that the first PRB of the second terminal is a PRB occupied by the second terminal itself, and the second PRB of the second terminal is a PRB to be scheduled to the second terminal, where the PRB to be scheduled to the second terminal may include a PRB occupied by the first terminal. When the second PRB is the PRB occupied by the first terminal, if the PRB occupied by the second terminal is scheduled for the first terminal, the quality index difference value between the PRB currently occupied by the second terminal and the PRB to be scheduled for the second terminal is considered. If the difference value of the two is smaller than the preset quality index difference value threshold value, the PRB currently occupied by the second terminal can be scheduled to the first terminal.

S504, if the difference value of the quality indexes of the first PRB and the second PRB of the second terminal is smaller than the preset quality index difference threshold value, the PRB occupied by the second terminal is scheduled to the first terminal.

It should be noted that, if the difference between the quality index of the PRB currently occupied by the second terminal and the quality index of the PRB to be scheduled to the second terminal is smaller than the preset quality index difference threshold, this means that the influence on the second terminal after the channel resource scheduling is performed is smaller, and the communication requirement of the first terminal can be satisfied.

In some embodiments of the present disclosure, as shown in fig. 6, the embodiments of the present disclosure further provide the following method steps:

s602, terminal subscription information of at least one terminal is obtained.

It should be noted that, in the resource scheduling process, the system may acquire terminal subscription information of at least one terminal. The terminal subscription information may include information about the service class, capacity requirement, resource guarantee requirement, terminal type, etc. of the terminal.

S604, determining the resource scheduling priority of each terminal according to the terminal subscription information of each terminal.

Based on the terminal subscription information of the terminals, the system determines a priority of resource scheduling for each terminal. This means that the system will decide the order and priority of resource scheduling according to the requirements and conventions of different terminals, so as to meet the requirements of each terminal as much as possible.

In some embodiments of the present disclosure, the terminal subscription information includes at least one of the following: public land mobile network PLMN information, quality of service class identifier QCI information.

It should be noted that PLMN represents a public land mobile network (Public Land Mobile Network), and PLMN information generally refers to an identifier of a mobile network connected to the terminal. By knowing the PLMN information to which the terminals are connected, the system can identify the resource scheduling priority of each terminal, i.e. determine whether the terminal is a first terminal or a second terminal.

The QCI represents a quality of service class identifier (QoS Class Identifier) for identifying different quality of service classes in the wireless communication system. Each QCI identifier represents a particular quality of service level, such as delay, throughput, reliability, etc. By knowing the QCI information of the terminals, the system can identify the resource scheduling priority of each terminal, i.e. determine whether the terminal is a first terminal or a second terminal.

In some embodiments of the present disclosure, as shown in fig. 7, a detailed embodiment application explanation of the present disclosure is made. The first terminal is a terminal used by the VIP user, the second terminal is a terminal used by the common user, and the resource scheduling priority of the first terminal is higher than that of the second terminal, namely, the resource scheduling priority of the VIP user is higher than that of the common user.

In step S702, the network side device obtains the channel condition according to the terminal measurement information, and in step S704, the sub-band PRBs with the sub-band CQI better than the full-band CQI are regarded as the PRB resources with better conditions according to the sub-band measurement result, and the sub-band PRBs are ordered according to the CQI value.

According to steps S702 and S704, PRBs satisfying the preset quality indicator condition can be selected. These PRBs satisfying the condition become PRBs to be scheduled as better-quality PRBs.

Step S706, whether the terminal is a terminal of the VIP user is judged according to the PLMN or QCI of the terminal, if yes, step S708 is executed, whether the better quality PRB is already occupied is continuously judged, if not occupied, step S710 is executed, such PRB resources are sequentially scheduled to the VIP user from high to low, if the better quality PRB is already occupied, step S712 is executed, whether the difference between the occupied scheduled resources of the ordinary user is greater than the preset quality index difference threshold, specifically, the channel measurement of the ordinary user is reported, if the difference between the currently occupied sub-band CQI (relatively better PRB resource) of the ordinary user and the non-scheduled sub-band CQI (relatively worse PRB resource) of the ordinary user is smaller than the threshold (within a reasonable interval, when the ordinary user is guaranteed to be preempted, the service experience is not obvious), step S714 is executed, the ordinary user is preempted relatively better PRB resources to the VIP user, if the difference is greater than the threshold, step S716 is executed, the ordinary user is not preempted resources, and the VIP user is executed according to the special scheduling policy.

In some embodiments of the present disclosure, step S714 may sequentially preempt relatively better PRB resources for the ordinary user to the VIP user from small to large according to the sub-band CQI gap, where the ordinary user schedules relatively worse PRB resources.

Based on the same inventive concept, the embodiments of the present disclosure also provide a channel resource scheduling apparatus, as described in the following embodiments.
