Figure 2 shows a flow chart of a channel resource scheduling method in an embodiment of the present disclosure. As shown in Figure 2, the channel resource scheduling method provided in an embodiment of the present disclosure includes the following steps:

S202: Obtain the channel status information reported by the first terminal.

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

In a multi-terminal communication system, each terminal has its own channel state information. This channel state information can be collected by the terminal device and sent to the network side device through specific signaling. Network-side devices can use this channel status information to perform dynamic resource allocation and scheduling to maximize the performance and reliability of data transmission under the current transmission environment.

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

It should be noted that a Physical Resource Block (PRB) is a basic unit used 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 during the channel resource scheduling process. In the communication system, the network side device schedules available channel resources to meet the communication needs of the first terminal. In order to make reasonable use of channel resources, the network side device will select an appropriate PRB for allocation based on the needs of the first terminal and the current network status.

The quality indicator information of the PRB to be scheduled can be any indicator information used to evaluate the quality of the PRB. These indicators can reflect the channel status, interference conditions and other performance characteristics of the PRB. Here is some common quality indicator information:

Channel Gain: Measures the reception strength of the wireless signal on the PRB. A higher channel gain indicates better signal quality.

Signal-to-Noise Ratio (SNR): represents the ratio of signal to noise. A higher signal-to-noise ratio indicates better signal quality.

Signal to Interference plus Noise Ratio (SINR): used to measure the degree of interference and indicate the signal quality level.

Channel Quality Indication (CQI): An indication value used to reflect channel quality.

Since the channel state information reported by the first terminal contains a lot of quality index information, that is, the quality index information of the physical resource block PRB to be scheduled can be determined based on the channel state information. The network side device can select appropriate PRBs to allocate to the terminal device based on these quality indicator information to improve system performance and user experience.

S206: Schedule channel resources for the first terminal according to the PRB that meets the preset quality index conditions.

It should be noted that channel resources can be scheduled for the first terminal according to the PRBs to be scheduled that meet the preset quality index conditions. The network side device can select and distribute PRBs that meet the preset quality index conditions according to the needs of the first terminal and the current communication system status.

Specifically, the preset quality index conditions may be any set of quality index conditions preset in the channel resource scheduling process, and are used to select PRBs that meet specific quality requirements. The specific values and setting methods of these preset quality indicator conditions depend on different scenarios and network requirements. Network-side devices can be appropriately adjusted and optimized based on actual conditions and algorithm strategies to achieve better system performance and user experience.

According to the resource scheduling method provided by the embodiment of the present disclosure, according to the channel status information reported by the first terminal, select a PRB that meets the preset quality index conditions and allocate it to the first terminal to reasonably schedule channel resources for the first terminal. Optimizes the communication experience of the first end user.

It should be noted that the acquisition, storage, use, and processing of data in the technical solution of this disclosure are all in compliance with the relevant provisions of national laws and regulations. The personal identity data and operations related to individuals, customers, and groups obtained in the embodiments of this disclosure are Various types of data, including data and behavioral data, have been authorized.

In some embodiments of the present disclosure, the physical resource blocks PRB to be scheduled include: PRBs of multiple subband channels. As shown in Figure 3, before scheduling channel resources for the first terminal according to the PRB that meets the preset quality index conditions, the following steps are also included:

S302: Obtain the channel quality indicator CQI value of each subband channel.

It should be noted that channel quality indicator (Channel Quality Indicator, CQI) is a kind of quality indicator information. CQI is used to reflect the quality status of the wireless channel within a specific time period. CQI is a kind of indication information measured by the first terminal and fed back to the network side device. Through the CQI value, the network side device can evaluate the channel quality to decide how to Allocate limited resources and adopt appropriate scheduling strategies based on the current channel conditions of the first terminal to provide better transmission quality and system performance.

S304: Determine whether the CQI value of each subband channel is greater than the preset channel quality indication threshold.

It should be noted that to determine whether the CQI value of each subband channel is greater than the preset channel quality indication threshold, the preset channel quality indication threshold needs to be determined. The channel quality indication threshold can be set according to specific system needs and performance requirements, and is usually determined by network planners and optimizers.

The CQI value of each subband channel is compared with the preset channel quality indication threshold. If the CQI value is greater than the preset channel quality indication threshold, it indicates that the channel quality of the subband channel is good; if the CQI value is less than or equal to the preset channel quality indication threshold, it indicates that the channel quality of the subband channel may be poor.

S306: Determine the PRB of the sub-band channel whose CQI value is greater than the preset channel quality indication threshold in each sub-band channel as a PRB that meets the preset quality index condition.

It should be noted that the PRBs to be scheduled include PRBs of multiple subband channels, so there may be multiple PRBs for subband channels whose CQI value is greater than the preset channel quality indication threshold in each subband channel. When performing channel resource scheduling, these multiple PRBs that meet the conditions can be taken into consideration 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 present disclosure, PRBs that meet the preset channel quality indication threshold are determined through the CQI value of the subband channel, and then one or more PRBs that meet the conditions are scheduled to the first terminal to provide the first terminal with Better communication quality.

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

It should be noted that the CQI value of the full-band channel may come from the channel state information reported by the first terminal. Determining whether the CQI value of each sub-band channel is greater than the preset channel quality indication threshold is to determine whether the CQI value of each sub-band channel is greater than the CQI value of the full-band channel.

By obtaining the channel state information reported by the first terminal, the CQI value of the full-band channel can be obtained as the preset channel quality indication threshold. Then, the CQI value of each sub-band channel is compared. If the CQI value of the sub-band channel is greater than the CQI value of the full-band channel, the corresponding PRB can be determined as a PRB that meets the preset quality index conditions.

The above scheduling method can effectively utilize the channel state information of the full-band channel for channel resource scheduling. The PRBs with sub-band channel CQI values greater than the CQI value of the full-band channel are regarded as PRB resources with better quality, and the quality evaluation criteria are determined. , to facilitate and better judge the quality of PRB.

In some embodiments of the present disclosure, as shown in Figure 4, after determining the PRB of the sub-band channel with a CQI value greater than the preset channel quality indication threshold in each sub-band channel as a PRB that satisfies the preset quality indicator condition, it is also Includes the following steps:

S402: Determine whether the PRB that meets the preset quality index condition is occupied by a second terminal, where the resource scheduling priority of the second terminal is lower than that of the first terminal.

It should be noted that if the resource scheduling priority of the second terminal is lower than that of the first terminal, it can be understood that the first terminal has a higher priority than the second terminal and is scheduled to the required channel resources. Generally, the first terminal may be a high-priority user terminal or a terminal with special needs, such as a terminal device of a VIP user. The second terminal may be an ordinary user or a terminal device with a lower priority.

By placing the second terminal with a lower resource scheduling priority at a lower resource acquisition priority, it can be ensured that the first terminal obtains the required resources first in the event of a resource conflict. This can maintain the fairness and efficiency of the communication system and meet the special needs of different terminals.

Whether the PRB that meets 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.

S404: If the PRBs that meet the preset quality index conditions are not occupied by the second terminal, sort the PRBs that meet the preset quality index conditions.

It should be noted that the PRBs that meet the preset quality index conditions can be multiple PRBs, and there can also be multiple PRBs that are not occupied by the second terminal. For multiple PRBs that are not occupied by the second terminal and meet the preset quality index conditions, The PRBs are sorted. The specific sorting basis can be the size of the CQI value, and the PRBs are sorted according to the CQI values of multiple PRBs.

S406: Schedule channel resources for the first terminal according to the sorting result.

According to the sorting result, channel resources can be scheduled and allocated for the first terminal according to the scheduling requirements of the first terminal.

During the resource scheduling process, according to the sorting result, an appropriate number of PRBs are selected from the top PRBs with better channel quality and allocated to the first terminal. The selected quantity can be determined based on actual needs and scheduling strategies. The goal of scheduling channel resources is to enable the first terminal to obtain high-quality signals and obtain better transmission performance and user experience for the first terminal. By allocating PRBs with higher CQI values, the first terminal can enjoy resources with higher channel quality.

In some embodiments of the present disclosure, as shown in Figure 5, after determining whether the PRB that meets the preset quality index conditions is occupied by the second terminal, the following steps are also included:

S502: If the PRB that meets the preset quality index condition is occupied by the second terminal, determine whether the quality index difference between the first PRB and the second PRB of the second terminal is greater than the preset quality index difference threshold, where 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 that meets the preset quality index condition is occupied by the second terminal, it means that the PRB with better quality has been occupied by the second terminal. 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 less than the preset quality index difference threshold, the PRB 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 the PRB occupied by the second terminal itself, and the second PRB of the second terminal is the PRB to be scheduled to the second terminal. The PRB to be scheduled to the second terminal may include PRB occupied by the first terminal. When the second PRB is a PRB occupied by the first terminal, if the PRB occupied by the second terminal is scheduled for the first terminal, the quality index difference between the PRB currently occupied by the second terminal and the PRB to be scheduled for the second terminal must be considered. value. If the difference between the two is less than the preset quality index difference threshold, then the PRB currently occupied by the second terminal can be scheduled to the first terminal.

S504: If the quality index difference between the first PRB and the second PRB of the second terminal is less than the preset quality index difference threshold, schedule the PRB occupied by the second terminal to the first terminal.

It should be noted that the quality index difference between the PRB currently occupied by the second terminal and the PRB to be scheduled to the second terminal is less than the preset quality index difference threshold, which means that the impact on the second terminal after channel resource scheduling is performed It is smaller and can meet the communication needs of the first terminal.

In some embodiments of the present disclosure, as shown in Figure 6, the embodiments of the present disclosure also provide the following method steps:

S602: Obtain terminal subscription information of at least one terminal.

It should be noted that during the resource scheduling process, the system will obtain terminal subscription information of at least one terminal. Terminal contracting information may include terminal service level, capacity requirements, resource guarantee requirements, terminal type and other related information.

S604: Determine the resource scheduling priority of each terminal according to the terminal subscription information of each terminal.

Based on the terminal's terminal subscription information, the system will determine the priority of resource scheduling for each terminal. This means that the system will determine the order and priority of resource scheduling based on the needs and agreements of different terminals to meet the needs 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 and quality of service category identifier QCI information.

It should be noted that PLMN represents Public Land Mobile Network (Public Land Mobile Network), and PLMN information usually refers to the identifier of the mobile network connected to the terminal. By understanding the PLMN information to which the terminal is connected, the system can identify and determine the resource scheduling priority of each terminal, that is, determine whether the terminal is the first terminal or the second terminal.

QCI stands for Quality of Service Class Identifier (QoS Class Identifier), which is used to identify different service quality levels in wireless communication systems. Each QCI identifier represents a specific quality of service level, such as latency, throughput, reliability, etc. By understanding the QCI information of the terminal, the system can identify and determine the resource scheduling priority of each terminal, that is, determine whether the terminal is the first terminal or the second terminal.

In some embodiments of the present disclosure, as shown in FIG. 7 , the present disclosure is explained in detail. The first terminal is a terminal used by VIP users, and the second terminal is a terminal used by ordinary users. The resource scheduling priority of the first terminal is higher than that of the second terminal, that is, the resource scheduling priority of VIP users is higher than that of ordinary users.

In step S702, the network side device obtains channel conditions based on the terminal measurement information. In step S704, based on the subband measurement results, the sub-band PRB with a sub-band CQI better than the full-band CQI is considered to be a PRB resource with better conditions, and based on the sub-band measurement results, CQI values are sorted by size.

According to steps S702 and S704, PRBs that meet the preset quality index conditions can be selected. These PRBs that meet the conditions become PRBs to be scheduled as PRBs with better quality.

Step S706: Determine whether the terminal is a VIP user's terminal according to the terminal's PLMN or QCI. If it is a VIP user, execute step S708 to continue to determine whether the PRB with better quality has been occupied. If not, execute step S710, sort by Such PRB resources are scheduled to VIP users in order from high to low. If the PRB with better quality is already occupied, step S712 is executed to continue to determine whether the difference in scheduling resources of occupied ordinary users is greater than the preset quality index difference threshold. Specifically, the channel measurement report of ordinary users, if the difference between the sub-band CQI currently occupied by the ordinary user (relatively good PRB resources) and its unscheduled sub-band CQI (relatively poor PRB resources) is less than the threshold (within a reasonable range , to ensure that when ordinary users are preempted, the service experience will not drop significantly), then execute step S714 to seize relatively good PRB resources for ordinary users and give them to VIP users, and ordinary users schedule relatively poor PRB resources. If the difference is greater than the threshold, execute Step S716: Ordinary user resources are not preempted, and VIP users are executed according to the normal scheduling policy without special operations.

In some embodiments of the present disclosure, step S714 can sequentially seize relatively good PRB resources for ordinary users and give them to VIP users according to the subband CQI gap from small to large, and ordinary users can schedule relatively poor PRB resources.
