Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of wireless communication technology, and in particular to a spectrum resource scheduling method, apparatus, computer equipment, and computer-readable medium. Background Art
[0002] Spectrum resources are one of operators' most important assets, and continuously improving spectrum utilization is a consistent goal. Due to historical reasons, operators often operate multiple networks simultaneously. After 5G deployment, 2G, 3G, 4G, and 5G will operate simultaneously. With the increasing demand for mobile broadband network traffic, operators are increasingly refarming their 2G / 3G networks to 4G, and vice versa. In traditional multi-standard networks, each standard requires a fixed allocation of spectrum resources. Since each standard has exclusive spectrum, spectrum cannot be shared across standards during peak hours, resulting in significant waste of spectrum resources. Spectrum sharing technology enables on-demand and dynamic scheduling of spectrum resources within the same frequency band, making it an inevitable choice for operators.
[0003] Taking 4G / 5G dynamic spectrum sharing as an example, 4G is a broadband system with relatively coarse channel configuration. Control channels, pilot signals, etc. are all mapped to the entire frequency band. 5G is also a broadband system with various physical channels. How to perfectly resolve the interference between the various physical channels of the two standards and improve the overall spectrum utilization of service channels on the shared spectrum requires the support of a coordinated and reasonable algorithm.
[0004] like Figure 1a As shown, a certain operator has currently deployed 3x20MHz TDD-LTE (Time Division Long Term Evolution) on the 2.6GHz band. If 100MHz bandwidth 5G NR (5G New Radio) is opened, it will conflict with the existing 4G TDD-LTE spectrum. The existing 4G network needs to release 2x20MHz bandwidth (2575-2615MHz), that is, two frequency points need to be cleared. Otherwise, only 60MHz bandwidth 5G can be opened at this stage, and the peak rate cannot compete with other operators. If two frequency points are opened on a large scale to replace the cleared frequency point, some terminals may not support the opened frequency point, resulting in RRC (Radio Resource Control) re-establishment failure due to reconfiguration. For a period of time, NR100M and the cleared frequency point will coexist. In order to fully utilize spectrum resources and reduce mutual interference between NR100M and LTE frequency points, a 4G / 5G spectrum sharing solution is created.
[0005] like Figure 1bAs shown in Figure 1, traditional dynamic spectrum sharing solutions share part of the 4G LTE frequency band with the 5G system based on the PRB (Physical Resource Block) utilization of the 4G LTE system. However, when 5G users are scheduled to occupy the shared spectrum, the MCS (Modulation and Coding Scheme) of the user scheduling cannot be increased, the peak rate cannot be effectively guaranteed, and the user experience does not significantly improve.

[0054] The inventors discovered that traditional dynamic spectrum sharing solutions currently only implement spectrum sharing functionality, simply adding 4G shared frequency bands to the existing 5G frequency band bandwidth. When spectrum sharing mode is enabled, the 5G cell scheduling algorithm fails to consider interference from surrounding 4G cells, impacting 5G user perception. Therefore, this disclosure proposes a spectrum resource scheduling method in spectrum sharing mode that performs separate evaluations on shared frequency bands, thereby improving overall user perception.
[0055] The present disclosure provides a spectrum resource scheduling method for scheduling spectrum resources of at least two coexisting network standards, wherein the two network standards include a first network standard and a second network standard. In the present disclosure, when the shared spectrum takes effect, the shared frequency band of the first network standard is used as a separate configuration BWP (Band Width Part) of the second network standard, which is recorded as BWP. share The BWP (i.e. original frequency band) of the second network standard is recorded as BWP old Thus, after sharing the spectrum, the bandwidth of the second network standard becomes (BWP share +BWP old ).
[0056] like Figure 2 As shown, the spectrum resource scheduling method provided by the embodiment of the present disclosure includes the following steps:
[0057] Step 11: Determine a channel quality parameter of a shared frequency band of a first network standard.
[0058] In this step, the preset evaluation period T is determined share The channel quality parameters of the shared frequency band of the first network standard.
[0059] Step 12: If the channel quality parameter meets the preset first condition, spectrum resources are scheduled in the shared frequency band of the first network standard, or spectrum resources are scheduled in the shared frequency band of the first network standard and the original frequency band of the second network standard.
[0060] The steps of evaluating whether the shared frequency band channel quality meets the first condition will be described in detail later.
[0061] The spectrum resource scheduling method provided by the embodiments of the present disclosure is used to schedule spectrum resources of at least two coexisting network standards, where the two network standards include a first network standard and a second network standard. The method includes: determining a channel quality parameter of a shared frequency band of the first network standard; if the channel quality parameter meets a preset first condition, scheduling spectrum resources within the shared frequency band of the first network standard, or scheduling spectrum resources within the shared frequency band of the first network standard and the original frequency band of the second network standard. In this way, by evaluating the channel quality of the shared frequency band and fully considering the interference of the shared frequency band on the user, the spectrum resources of the shared channel can be called only when the channel quality of the shared frequency band meets certain conditions, thereby optimizing the scheduling and use of the shared frequency band and improving user perception.
[0062] In the embodiment of the present disclosure, the channel quality parameter is a parameter used to reflect the quality of the channel. In some embodiments, the channel quality parameter includes but is not limited to spectrum efficiency and / or evaluation period (ie, T share) within the average channel quality indicator, it should be noted that the spectrum efficiency is T share spectral efficiency within.
[0063] When the channel quality parameter is spectral efficiency, the channel quality parameter meeting the preset first condition includes: the spectral efficiency is greater than a preset first threshold. When the channel quality parameter includes an average channel quality indicator within a preset evaluation period, the channel quality parameter meeting the preset first condition includes: the average channel quality indicator within the preset evaluation period is greater than a preset second threshold. When the channel quality parameter includes both spectral efficiency and the average channel quality indicator within a preset evaluation period, the channel quality parameter meeting the preset first condition includes: the spectral efficiency is greater than the preset first threshold, and the average channel quality indicator within the preset evaluation period is greater than a preset second threshold.
[0064] In some embodiments, if the channel quality parameter meets a preset first condition, the step of scheduling spectrum resources, that is, scheduling spectrum resources within the shared frequency band of the first network standard, or scheduling spectrum resources within the shared frequency band of the first network standard and the original frequency band of the second network standard, includes: prioritizing scheduling spectrum resources within the shared frequency band of the first network standard.
[0065] In some embodiments, the prioritizing of scheduling spectrum resources within the shared frequency band of the first network standard includes: if the spectrum resources within the shared frequency band of the first network standard meet user needs, then scheduling spectrum resources within the shared frequency band of the first network standard; if the spectrum resources within the shared frequency band of the first network standard do not meet user needs, then scheduling spectrum resources within the original frequency band of the second network standard after scheduling spectrum resources within the shared frequency band of the first network standard. In other words, the spectrum resources within the shared frequency band of the first network standard are first scheduled, and when the spectrum resources within the shared frequency band are insufficient, the spectrum resources within the original frequency band of the second network standard are then utilized.
[0066] After the channel quality evaluation of the shared frequency band of the first network standard is passed (i.e., the channel quality of the shared frequency band is good), the embodiment of the present disclosure further determines whether the spectrum resources in the shared frequency band can meet the user needs, and gives priority to using the spectrum resources in the shared frequency band, thereby saving the spectrum resources of the original frequency band of the second network standard.
[0067] In some embodiments, according to a preset scheduling period (T max ) Determine the channel quality parameters of the shared frequency band of the first network standard. In other words, the spectrum resources in the shared channel are scheduled according to the scheduling period, so that the spectrum resource scheduling can be flexibly adjusted to improve real-time performance.
[0068] In some embodiments, the spectrum resource scheduling method disclosed herein may further include the following steps: if the channel quality parameter does not meet the first condition, scheduling spectrum resources within the original frequency band of the second network standard. In other words, when the channel quality of the shared frequency band of the first network standard is poor, spectrum resources within the shared frequency band are not scheduled, and instead spectrum resources within the original frequency band of the second network standard are scheduled, thereby ensuring user service stability and improving user perception.
[0069] In some embodiments, in order to further reasonably schedule spectrum resources, such as Figure 3 As shown, before evaluating the channel quality of the shared frequency band of the first network standard, that is, before determining the channel quality parameter of the shared frequency band of the first network standard (step 11), the spectrum resource scheduling method of the present disclosure may further include the following steps:
[0070] Step 10: Determine the user level, user service type, and physical resource block utilization rate of the original frequency band of the second network standard.
[0071] In this step, after the user terminal accesses the network, the user level, user service type and physical resource block utilization rate of the original frequency band of the second network standard are determined.
[0072] In the embodiment of the present disclosure, the user level refers to the level of user importance, for example, a VIP user. The user level can be obtained from the operator's equipment. Generally, the higher the communication fee cost of the user, the higher the user level.
[0073] The user service type can be determined by obtaining QoS (Quality of Service) parameters. Specifically, the user service type can be determined based on QoS indicators such as latency, latency variation (including jitter and drift), and packet loss rate. In the embodiments of the present disclosure, the preset type of user service refers to a user service with low latency and high reliability, such as a voice call service.
[0074] Accordingly, determining the channel quality parameter of the shared frequency band of the first network standard (ie, step 11) includes the following steps:
[0075] Step 11 ′: if the user level, user service type, and physical resource block utilization rate of the original frequency band of the second network standard meet a preset second condition, then determine the channel quality parameter of the shared frequency band of the first network standard.
[0076] In this step, if the user level, user service type and physical resource block utilization rate of the original frequency band of the second network standard meet the preset second condition, it means that it is preliminarily determined that the spectrum resources of the shared frequency band of the first network standard can be scheduled. As to whether the spectrum resources of the shared frequency band of the first network standard can be actually scheduled in the end, it is necessary to further evaluate the channel quality of the shared frequency band (i.e., execute step 11).
[0077] In the embodiment of the present disclosure, when calling spectrum resources, the user level, user service type and the physical resource block utilization rate of the original frequency band of the second network standard are comprehensively considered, so that the spectrum resource calling is more reasonable, the stability of the user service is improved, and the user experience and perception are guaranteed.
[0078] In some embodiments, the user level, user service type, and physical resource block utilization of the original frequency band of the second network standard meet a preset second condition, including: the user level is less than the preset level, and the physical resource block utilization of the original frequency band of the second network standard is greater than a preset fourth threshold, and the user service type is a non-preset type. The fourth threshold is the load threshold of the original frequency band bandwidth in the shared mode. In other words, for users with lower user levels who use non-preset user services, and the physical resource block utilization of the original frequency band of the current second network standard is relatively high, since the user and the service itself do not have too high requirements for spectrum resources, spectrum resources in the shared frequency band of the first network standard can be scheduled for the user.
[0079] In some embodiments, the spectrum resource scheduling method of the embodiment of the present disclosure further includes the following steps: if the user level, user service type, and physical resource block utilization rate of the original frequency band of the second network standard do not meet the second condition, then scheduling spectrum resources within the original frequency band of the second network standard. In this step, if the user level, user service type, and physical resource block utilization rate of the original frequency band of the second network standard do not meet the second condition, it is determined that the spectrum resources of the shared frequency band of the first network standard cannot be scheduled, otherwise it will affect the user service reliability and user experience. Therefore, in this case, the spectrum resources are scheduled within the original frequency band of the second network standard to ensure service reliability and user experience.
[0080] In some embodiments, the user level, user service type, and physical resource block utilization of the original frequency band of the second network standard do not meet the second condition, including one of the following (1)-(3):
[0081] (1) The user level is greater than or equal to the preset level;
[0082] (2) The user level is lower than the preset level and the physical resource block utilization rate of the original frequency band of the second network standard is lower than or equal to a preset fourth threshold;
[0083] (3) The user level is lower than the preset level and the physical resource block utilization rate of the original frequency band of the second network standard is greater than a preset fourth threshold and the user service type is a preset type.
[0084] That is, for higher-level users, spectrum resources within the original frequency band of the second network standard are scheduled for them to ensure service reliability and user experience. In the case where the utilization rate of the physical resource blocks in the original frequency band of the second network standard is low, spectrum resources within the original frequency band of the second network standard can also be scheduled for lower-level users. In the case where the utilization rate of the physical resource blocks in the original frequency band of the second network standard is high, although the user level is low, it is currently using low-latency, high-reliability services, and spectrum resources within the original frequency band of the second network standard can also be scheduled for it to ensure service reliability.
[0085] In some embodiments, after completing one scheduling operation, it may be further determined whether spectrum resources need to be scheduled again to ensure that user services are completed. That is, after scheduling spectrum resources within the original frequency band of the second network standard, or after scheduling spectrum resources within the shared frequency band of the first network standard, or after scheduling spectrum resources within the shared frequency band of the first network standard and the original frequency band of the second network standard, the spectrum resource scheduling method further includes the following steps:
[0086] Determine whether it is still necessary to schedule spectrum resources. If so, determine the current physical resource block utilization rate of the original frequency band of the second network standard for users whose user level is less than the preset level, and schedule spectrum resources (i.e., execute step 11') based on the judgment result of whether the user level, user service type, and the current physical resource block utilization rate of the original frequency band of the second network standard meet the second condition. Alternatively, schedule spectrum resources within the original frequency band of the second network standard for users whose user level is greater than or equal to the preset level. It should be noted that since the user level and user service type will not change in the short term, while the current physical resource block utilization rate of the original frequency band of the second network standard changes in real time, when it is determined that spectrum resources still need to be scheduled, for users whose user level is less than the preset level, it is sufficient to re-determine the current physical resource block utilization rate of the original frequency band of the second network standard.
[0087] In order to clearly illustrate the solutions of the embodiments of the present disclosure, an exemplary implementation of the above method of the present disclosure is described in detail below in conjunction with specific embodiments.
[0088] In the embodiment of the present disclosure, the spectrum resources of two network standards are scheduled as an example, where the first network standard is 4G and the second network standard is 5G. The 5G cell obtains the shared frequency band of the 4G LTE cell and sets a BWP on the shared frequency band, which is recorded as BWP.share , one or more BWPs are set on the original frequency band of the 5G cell, recorded as BWP old The channel quality parameter of the shared frequency band is the spectrum efficiency E share .
[0089] like Figure 4 As shown, the spectrum resource scheduling method of the embodiment of the present disclosure includes the following steps:
[0090] Step 401: Determine the user level, user service type, and PRB utilization rate P of the original frequency band of the 5G cell. PRBold .
[0091] Step 402 , determining whether the user level is greater than a preset level, if so, executing step 408 , otherwise executing step 403 .
[0092] In this step, if the user is determined to be a higher-level user (such as a VIP user), the user is directly old Internal scheduling spectrum resources (i.e., executing step 408); if it is determined that the user is a lower-level user, it is also necessary to combine P PRBold Further judgment is made based on the user's service type (ie, step 403 is executed).
[0093] Step 403, determine P PRBold Is it greater than P expection (ie, the fourth threshold), if yes, execute step 404, otherwise, execute step 408.
[0094] In this step, if it is determined that P PRBold >P expection , then it is necessary to further determine the user service type (i.e., execute step 404); if it is determined that P PRBold ≤P expection , then in BWP old Internally schedule spectrum resources (i.e., execute step 408).
[0095] Step 404 , determining whether the user service type belongs to the preset type, if not, executing step 405 ; if yes, executing step 408 .
[0096] In this step, if it is determined that the user service type does not belong to the low-latency and high-reliability service type, it is necessary to further evaluate the channel quality of the shared channel (i.e., execute step 405); if it is determined that the user service type belongs to the low-latency and high-reliability service type (i.e., the preset type), then in BWP old Internally schedule spectrum resources (i.e., execute step 408).
[0097] Step 405: Determine the evaluation period T share Spectral efficiency E in the shared periodshare .
[0098] Step 406, determine E share Is it greater than the first threshold E expection If it is greater than, execute step 407; otherwise, execute step 408.
[0099] In this step, if it is determined that E share >E expection , indicating that the first condition is met, then you can share Internal scheduling spectrum resources (i.e., executing step 407); if it is determined that E share ≤E expection , indicating that the first condition is not met, then in BWP old Internally schedule spectrum resources (i.e., execute step 408).
[0100] Step 407, in BWP share Schedule spectrum resources within, or, within (BWP share +BWP old ) to schedule spectrum resources within.
[0101] In this step, (T max -T share ) time period to schedule spectrum resources.
[0102] Step 408, in BWP old Internal scheduling of spectrum resources.
[0103] It should be noted that after steps 407 and 408, the following steps are further included: determining whether spectrum resources need to be scheduled; if not, ending the process; if necessary, determining P for lower-level users; PRBold , and judge P PRBold Is it greater than P expection (i.e., execute step 403), and, for higher-level users, directly in BWP old Internally schedule spectrum resources (i.e., execute step 408).
[0104] The spectrum resource scheduling method provided by the embodiments of the present disclosure can overcome the problem in the prior art that no evaluation is performed on the shared frequency band, and the 4G shared frequency band is simply added to the bandwidth of the 5G original frequency band, thereby affecting the 5G user perception. It achieves the effect of optimizing the scheduling and use of the 4G shared frequency band and improving user perception.
[0105] Based on the same technical concept, the embodiment of the present disclosure also provides a spectrum resource scheduling device, such as Figure 5As shown, the spectrum resource scheduling device includes a first determination module 1 and a scheduling module 2. The first determination module 1 is used to determine the channel quality parameter of the shared frequency band of the first network standard.
