Description

Resource management method, device and equipment and computer storage medium

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a device for resource management, and a computer storage medium.

Background

In a wireless communication system, a Channel state information reference signal (CSI-state Information Reference Signal, abbreviated as CSI-RS) is a New downlink physical signal of an air interface (New Radio, abbreviated as NR), and a User Equipment (UE) measures its progress to obtain relevant Channel information and reports the relevant Channel information to a base station.

The uplink sounding reference signal (Sounding Reference Signal, abbreviated SRS) is an NR uplink physical signal, the UE transmits the SRS in the system bandwidth of the serving cell, and the base station receives and processes the SRS of the UE to obtain corresponding information such as signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, abbreviated SINR), reference signal received power (Reference Signal Received Power, abbreviated RSRP), precoding matrix indication (Precoding Matrix Indication, abbreviated PMI), and the like.

In general, when configuring the corresponding CSI-RS and SRS resource types for different serving cells, the base station may be configured to be one of periodic, aperiodic and semi-static, and when configuring the bandwidth range for transmitting CSI-RS or SRS detection, may also be configured to be a fixed bandwidth range to meet the transmission requirement of CSI-RS or the requirement of SRS detection.

However, once the base station completes the resource allocation for different service cells, the proposed resource allocation will remain in a substantially unchanged state regardless of the actual situation of the online UEs in the service cells, which results in that when the communication situation of the UEs in the service cells changes, the resource allocation of the base station cannot be adjusted in time, and thus the situation that the resource allocation provided by the base station does not match with the actual use requirement occurs.

Therefore, a method for resource management is needed to improve the flexibility of the base station for resource allocation, thereby reducing the energy consumption of the base station.

In the field of wireless communication, when a base station configures corresponding CSI-RS and SRS resource types for different serving cells, the resource types can be configured as one of periodic, aperiodic and semi-static, and meanwhile, when the bandwidth range for transmitting CSI-RS or SRS detection is configured, the base station can also be configured as a fixed bandwidth range to meet the transmission requirement of CSI-RS or the requirement of SRS detection.

However, in this manner, once the base station completes the configuration of the resource type and the bandwidth range after activating the cell, the proposed resource configurations will remain in a substantially unchanged state regardless of the actual situation of the load in each serving cell, which results in that, when the communication situation of each UE in the serving cell changes, the resource configuration of the base station cannot be adjusted in time, and thus, the situation that the resource configuration provided by the base station does not match with the actual use requirement occurs.

In view of this, the present application provides a method, an apparatus, a device, and a computer storage medium for resource management, so as to improve flexibility of a base station for resource allocation, and further reduce energy consumption of the base station.

Meanwhile, the base station can acquire the utilization rate of a physical Resource Block (RB) corresponding to the current moment of the target cell, and configures a corresponding bandwidth range for the cell with different RB utilization rates according to the condition that the RB utilization rate is matched with a preset utilization rate range, so that the bandwidth range allocated for the cell can always bear the load of the cell without excessive waste, and further the energy consumption of the base station is reduced.

Referring to fig. 1, a network architecture diagram of a communication system including a network device and a terminal device, to which the embodiments of the present application are applicable, is shown.

Wherein the terminal device, which may also be referred to as a terminal, is also referred to as user equipment UE. May be a device that provides voice and/or data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. The wireless user equipment may communicate with one or more core networks via a radio access network (english: radio Access Network, abbreviated RAN), which may be mobile terminals, such as mobile phones (or "cellular" phones) and computers with mobile terminals, for example, portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access network.

The base station may be configured to inter-convert the received air frames with Internet Protocol (IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network. The network device may also coordinate attribute management for the air interface. For example, the network device may include an evolved Node B (NodeB or eNB or e-NodeB, evolved Node B) in a long term evolution (english: long term evolution, abbreviated LTE) system or advanced, long term evolution (english: long term evolution-advanced, abbreviated LTE-a), or may also include a next generation Node B (english: next generation Node B, abbreviated gNB) or a next generation evolved Node B (english: next generation evolved nodeB, abbreviated ng-eNB), en-gNB (english: enhanced next generation Node B, abbreviated gNB) in a fifth generation mobile communication technology (english: the 5th generation, abbreviated 5G) NR system: enhanced next generation base stations; centralized units (abbreviated CU) and distributed units (abbreviated DU) in a Cloud access network (english: cloud radio access network, abbreviated Cloud RAN) system may also be included, or relay devices may also be included, and embodiments of the present application are not limited.

It should be understood that in practical application, the number of network devices and the number of terminal devices are not limited to 1; in addition, the network devices may also communicate with each other, and the terminal devices may also communicate with each other, which is not limited in this application.

The audio and video synchronization method provided in the exemplary embodiments of the present application will be described below with reference to the accompanying drawings in conjunction with the application scenario described above, and it should be noted that the application scenario described above is only shown for the convenience of understanding the spirit and principles of the present application, and embodiments of the present application are not limited in any way in this respect.

Referring to fig. 2, a flowchart of a resource management method provided in an embodiment of the present application will be described with reference to a base station as an execution body in the following description for convenience of understanding. As shown in fig. 2, a specific embodiment of the method is as follows:

step S201: and determining the number of online UEs of the target cell in response to the access request of the target UE for the target cell.

In the method shown in fig. 2, although only the processing manner of the UE corresponding to the target cell by the base station is described, other cells of the base station or other cells of other base stations may perform the method at the same time. However, for convenience of explanation, the method shown in fig. 2 will be described below by taking a base station-target cell as an example.

After completing activation of the target cell, the base station may receive the access request from each UE, and in this embodiment of the present application, each time the base station receives the access request from the target UE, the base station may determine, in response to the received access request, the number of on-line UEs of the target cell corresponding to the access request, so as to provide a data base for configuring the resource type for the UE.

Step S202: based on the online UE number of the target cell and a preset terminal number threshold value, configuring corresponding resource types for the target UE; wherein the resource type is used to indicate the manner of transmitting the CSI-RS or SRS.

After the base station determines the online UE number of the target cell, the base station can configure corresponding resource types for the target UE based on the online UE number and a preset terminal number threshold value, so as to instruct a mode of transmitting CSI-RS or performing SRS detection.

Specifically, after the base station acquires the number of online UEs of the target cell, the base station can determine the resource type to be configured for the target UE according to the relationship between the number of online UEs and the threshold of the number of terminals. Then, the base station transmits RRC configuration information to the target UE by establishing a radio resource control (english: radio Resource Control, abbreviated RRC) connection with the target UE such that the target UE is configured to a corresponding resource type.

It should be noted that, the specific value of the threshold of the number of terminals may be set according to the use requirement in practical application, which is not limited in this application.

Optionally, when configuring a corresponding resource type for the target UE based on the number of online UEs and a preset terminal number threshold, the method may be specifically implemented as follows.

Referring to fig. 3, a flowchart of a method for configuring a resource type for a target UE according to an embodiment of the present application is shown in fig. 3, where the method specifically includes the following implementation steps:

step S301: and judging whether the online UE number of the target cell is greater than a terminal number threshold, if so, executing step S302, and if not, executing step S303.

Step S302: configuring a resource type corresponding to the target UE as a period type;

Step S303: and configuring the resource type corresponding to the target UE as an aperiodic type or a semi-static type.

Wherein, the periodic type, the aperiodic type and the semi-static type are one of the above resource types, and specifically, for the periodic type, the transmission modes for the CSI-RS and the SRS are: and the periodic CSI-RS and SRS are transmitted at a fixed time-frequency position, wherein the CRI-RS is that the cell transmits at the fixed time-frequency position, the SRS is that the UE transmits the SRS at the fixed time-frequency position, and the base station detects the SRS at the corresponding fixed time-frequency position.

For the aperiodic type, the transmission modes for CSI-RS and SRS are: after the cell is activated, the cell performs aperiodic CSI-RS transmission at the time domain and frequency domain positions where the CSI-RS resource can be deployed, and after the UE receives the configuration of the aperiodic type resource type, the UE needs to receive the trigger of the corresponding downlink control information (english: downlink Control Information, abbreviated as DCI) and then transmits the corresponding SRS.

For the semi-static type, the transmission modes for CSI-RS and SRS are: similar to the aperiodic type, the UE needs to receive activation of a media access Control (english: media Access Control, abbreviated MAC) Control Element (english: control Element, abbreviated CE) before periodically transmitting SRS.

As can be seen from the above different resource types, for the transmission modes of the aperiodic type and the semi-static type, a certain amount of communication resources are consumed to transmit DCI or MAC CE, so that CSI-RS and SRS are transmitted, which occurs when the number of online UEs in a cell is greater, more communication resources are required to afford DCI or MAC CE transmission, resulting in reduced performance of the base station.

Therefore, the present application proposes that when receiving an access request of a target UE for a target cell, the method determines according to the number of online UEs in the cell, and when the number of online UEs in the cell exceeds a preset terminal number threshold, configures a resource type of a newly accessed UE as a periodic type, so as to avoid excessive consumption of resources of DCI or MAC CE.

When the number of the on-line UE of the cell does not exceed the preset terminal number threshold, the cell data scheduling pressure is proved to be smaller, and idle resources can be used for transmitting DCI or MAC-CE, so that the semi-static type or non-periodic type resource type can be configured for the target UE.

Thus, different resource types can be flexibly configured for the UE based on the load of the cell.

In the scheme, aiming at different online UE numbers of the target cell, the base station can configure different resource types for the target UE, so that the UE accessed to the target cell can acquire the resource type more matched with the actual load of the target cell, thereby avoiding the waste of excessive unobjectionable communication resources generated by the base station and reducing the energy consumption of the base station.

Optionally, after completing the configuration of the resource type for the target UE that newly accesses the target cell, the base station may also perform adjustment of the resource type for the online UE that has already accessed the target cell.

Since the online UEs in the target cell all experience the configuration of the resource types when accessing the target cell, each online UE in the cell has a corresponding resource type. And when the configuration of the resource types is completed for other online UEs in the target cell, the number of online UEs in the target cell may change in a period of time from when the target UE accesses the target cell, so that the configuration of the resource types obtained when the target UE accesses the target cell is different from the configuration of the resource types obtained by other online UEs in the target cell.

At this time, the base station may determine, according to the resource types corresponding to the target UE, the resource types that should be configured by other online UEs having different resource types corresponding to the target UE in the target cell, and adjust the resource types of other online UEs having different resource types corresponding to the target UE in the target cell by sending RRC reconfiguration information to the other online UEs.

For convenience of explanation, one of the online UEs in the target cell will be referred to as a first UE, and then a manner of adjusting other online UEs will be explained using the first UE as an example.

In a possible implementation manner, as shown in fig. 4, after completing the configuration of the resource type of the target UE, the base station may adjust the resource type of other online UEs (such as the first UE and the second UE in fig. 4) with different resource types corresponding to the target UE in the target cell to the resource type corresponding to the target UE, no matter what resource type is configured for the target UE.

Specifically, when determining that the resource type corresponding to the first UE in the target cell is different from the resource type corresponding to the target UE, the base station may adjust the resource type corresponding to the first UE, so that the resource type corresponding to the first UE is the same as the resource type corresponding to the target UE.

In the method, the base station can timely modify the resource types of the online UE of the cell according to the change of the online UE number of the cell, so that the resource types of all the online UE in the cell can meet the current load state of the cell, and the base station does not need to carry out additional judgment, thereby improving the resource allocation efficiency of the base station.

In a possible implementation manner, the base station may determine a resource type configured for the target UE, adjust a resource type of other online UEs in the target cell, which are different from the resource type corresponding to the target UE, when determining that the resource type configured for the target UE is not a periodic type, and keep the resource type of the other online UEs unchanged when determining that the resource type configured for the target UE is a periodic type, and perform corresponding CRI-RS transmission and SRS detection through the original resource types of the UEs.

Specifically, referring to fig. 5, a flowchart of another method for adjusting a resource type of an online UE according to an embodiment of the present application is shown in fig. 5, where the method specifically includes the following implementation steps:

step S501: judging whether the resource type corresponding to the target UE is a periodic type, if not, executing step S502: if yes, step S503 is executed.

Step S502: when the resource type corresponding to the first UE is a periodic type, the resource type corresponding to the first UE is adjusted to be a non-periodic type or a semi-static type.

When the configured resource type of the target UE is determined to be a non-periodic type or a semi-static type, it can be determined that the number of online UEs of the target cell does not exceed the terminal number threshold at the moment, in other words, the number of online UEs of the target cell at the current moment is less, and the resource consumption of the current DCI of the base station is in an affordable range. Therefore, the base station can adjust the resource types of other online UEs except the target UE in the target cell to the resource types corresponding to the target UE.

Step S503: and sending the CSI-RS to the first UE or performing SRS detection on the first UE by using the resource type corresponding to the first UE.

In other words, when determining that the resource type configured for the target UE is the periodic type, the base station may select to keep the resource type corresponding to the first UE, and correspondingly perform the CSI-RS transmission process and the SRS detection process for the first UE based on the original resource type.

When the resource type configured by the target UE is determined to be the periodic type, it can be determined that the number of on-line UEs of the target cell exceeds the threshold of the number of terminals at the moment, and then the base station can perform corresponding processing on the on-line UEs of the target cell at the current moment by maintaining the configuration of the respective resource types of other on-line UEs in the current target cell and continuing to perform corresponding processing based on the respective resource transmission modes corresponding to the respective resource types of the on-line UEs. It should be clear that, when the base station determines that the number of online UEs in the target cell exceeds the threshold of the number of terminals, the resource types corresponding to the original online UEs in the target cell are only in two states:

one is: the resource type of one part of online UEs in the target cell is of an aperiodic type or a semi-static type, the resource type of the other part of online UEs is of a periodic type, the total number of UEs of which the resource type is of the aperiodic type or the semi-static type does not exceed the threshold of the number of terminals, and the communication resources consumed each time when the CSI-RS and the SRS are transmitted are limited, so that the resources consumed within the affordable range of the base station are consumed, and therefore, the base station does not need to transmit additional resource configuration instructions for the UEs.

And the second is: the resource types of all online UEs in the target cell are periodic types, so that the base station is faced with online UEs with the same resource types at the moment, and the base station does not need to adjust the corresponding resource types for the online UEs naturally.

In the method, after facing the target UE configured with different resource types, the base station can execute different resource adjustment strategies for the original online UE in the target cell.

Aiming at different online UE numbers, the base station can configure different resource types for the target UE, and can also adjust corresponding resource types for the online UE of the target cell in different modes, so that the flexibility of the scheme is improved, and meanwhile, the energy consumption of the base station is reduced.

Alternatively, in the specific application process of the two possible embodiments, it may be determined which embodiment is specifically selected to be applied through the difference between the threshold number of terminals.

From the two possible embodiments described above, the difference is whether the base station needs to adjust the resource types of other online UEs of the target cell after configuring the resource types of the periodic types for the target UE. To clarify the distinction, the following will be described by way of example.

For example, assuming that there are 20 online UEs in the target cell, and the threshold of the number of terminals corresponding to the target cell is also 20, when the base station receives the access request of the target UE for the target cell, the resource type of the 21 st UE is configured as a period type. At this time, for the resource types of the original UEs in the target cell, the base station may have two choices, one is to send instructions to all 20 UEs, adjust the resource types of the 20 UEs to be periodic types, and at this time, the base station does not need to send DCI or MAC CE required by the aperiodic type or the semi-static type to the 20 UEs; and secondly, the resource types of the 20 UEs are maintained, DCI or MAC CE is continuously sent to the 20 UEs to ensure that the UE can transmit information on the corresponding resources, and at the moment, an instruction for adjusting the resource types is not required to be sent to the UE.

Therefore, the threshold number of terminals is an important reference parameter when one of the two embodiments is selected for practical application. For convenience of explanation, the communication resources consumed by the base station to transmit the instruction for resource type adjustment to the UE will be referred to as a first indication cost, and the communication resources consumed by the base station to transmit the DCI or MAC CE to the UE will be referred to as a second indication cost.

Then, for a base station, a corresponding energy consumption threshold may be set, where the energy consumption threshold is used to indicate that when a preset number of online UEs exist in the target cell, the first indication cost and the second indication cost corresponding to the target cell are equal.

Thus, when the threshold of the number of terminals corresponding to the target cell is greater than the energy consumption threshold, it means that: when the resource type corresponding to the target UE newly accessing the target cell is configured as a periodic type, the first indication cost of the base station indicating the online UEs will be greater than the corresponding second indication cost for all online UEs existing in the target cell.

For example, when the energy consumption threshold is 30 and the threshold of the number of terminals is 40 and the number of UEs currently on-line in the target cell is also 40, then the resource type corresponding to the newly accessed target UE is configured as a period type. At this time, for the base station, an indication is sent to 40 UEs on-line in the target cell, and the first indication cost for indicating that the resource types corresponding to these UEs consume from the original aperiodic type or semi-static type is greater than the corresponding second indication cost, and when the corresponding resource allocation mode is selected for the base station, the method may be pre-selected as follows: the original resource types of other online UE except the target UE in the target cell are maintained, and the resource configuration mode of the resource types of the other online UE is not adjusted.

Therefore, when the threshold value of the number of terminals corresponding to the target cell is larger than the energy consumption threshold, the original resource types of other online UEs except the target UE in the target cell can be selected and kept for the base station, and the resource configuration mode of the resource types of the other online UEs is not adjusted.

When the threshold value of the number of terminals corresponding to the target cell is smaller than the energy consumption threshold, the method means that: when the resource type corresponding to the target UE newly accessed to the target cell is configured to be a periodic type, the base station sends a first indication cost corresponding to an instruction for resource type adjustment to the online UE of the target cell for all online UEs existing in the target cell, wherein the first indication cost is smaller than the corresponding second indication cost. Therefore, when the threshold value of the number of terminals corresponding to the target cell is smaller than the energy consumption threshold, the base station can select: and adjusting the resource types of other online UEs of the target cell based on the resource type corresponding to the target UE no matter which resource type the target UE is.

When the threshold of the number of terminals is equal to the threshold of the energy consumption, one of the two modes can be arbitrarily selected.

The specific value of the energy consumption threshold for the base station can be determined according to the historical data of different implementations of the base station, and can be estimated and determined according to actual use requirements, and the method is not limited.

In one possible implementation, when the base station adjusts the resource types of other online UEs, the base station may determine whether to adjust the resource types of other online UEs by increasing the time interval between adjustment operations in addition to the resource types of the target UEs.

As described above, in a period of time between the base station configuring the resource type for the other online UEs of the target cell and the base station configuring the resource type for the target UE, the base station may change the resource types configured for different UEs due to the change of the number of online UEs. And such variations may not be significant over a range of times. For example, if multiple UEs access the target cell within 1 second, the base station needs to determine the original online UE every time a new UE accesses the target cell, but in reality, the number of resource adjustments for other online UEs is not very large, and excessive determination actions may increase the base station energy consumption instead.

Therefore, in this embodiment, the base station may increase the judgment of the time interval in the process of determining whether to adjust the resource type of the other online UE of the target cell or how to adjust the resource type of the target UE, in addition to the judgment based on the resource type of the target UE.

Specifically, after the base station configures the corresponding resource type for the target UE, the base station continues to judge the adjustment time interval between the time point of the target UE accessing the target cell and the time point of the last adjustment of the resource types of other online UEs of the target cell, and if the adjustment time interval is determined to be greater than the preset time threshold, the base station can adjust the resource types of other online UEs of the target cell at the same time after the target UE accesses the target cell. If the adjustment time interval is determined to be smaller than or equal to the preset time threshold, the resource types of other online UEs are not adjusted, and CRI-RS transmission or SRS detection is continuously performed based on the original resource types of the other online UEs.

Therefore, the base station adjusts the resource types of the UE in the cell at a proper frequency, so that not only can the increase of energy consumption caused by excessive adjustment be avoided, but also the problem that the resource types are not matched with the actual conditions caused by long-term adjustment can be avoided.

Alternatively, for the above embodiments, they may be performed in a proper combination, for example, the first embodiment may be combined with the third embodiment to perform adjustment on the UE resource type, and the second embodiment may be combined with the third embodiment to perform adjustment on the UE resource type. Therefore, the energy consumption of the base station is further reduced while the effect of flexibly adjusting the resource types of the online UE corresponding to the cell is achieved.

The above introduces a scheme that when a new UE requests to access a target cell, a base station configures a corresponding resource type for the new UE, and simultaneously adjusts the corresponding resource type for other online UEs in the target cell.

On the other hand, while adjusting the resource type corresponding to the UE, the base station can also adjust the bandwidth range corresponding to the cell according to the actual load condition of the cell, so that the energy consumption of the base station is reduced while meeting the bandwidth requirement of the cell. The bandwidth range refers to a percentage between a bandwidth occupied by CSI-RS and SRS transmission processes and a total bandwidth corresponding to a cell in a communication process between a base station and a terminal in the cell.

Specifically, referring to fig. 6, a flowchart of a method for adjusting bandwidth ranges provided in an embodiment of the present application is shown in fig. 6, where the method specifically includes the following implementation steps:

step S601: and obtaining the target RB utilization rate corresponding to the current moment of the target cell.

In the step, after the base station obtains the target RB utilization rate corresponding to the target cell at the current moment, the bandwidth range of the target cell can be adjusted according to the RB utilization rate; the bandwidth range is used for indicating the bandwidth range corresponding to the CSI-RS and the bandwidth range corresponding to the SRS.

It should be understood that, the implementation timing of the method may be set at a preset time point, so that the base station obtains the RB utilization rate of the target cell at a specified time, or the trigger of step S601 may be implemented by receiving the trigger instruction, which is not limited in this application.

Step S602: adjusting the bandwidth range corresponding to the target cell based on the target bandwidth range corresponding to the target RB utilization; the bandwidth range corresponding to the target cell is used for indicating the bandwidth range corresponding to each of the CSI-RS and the SRS.

After obtaining the target RB utilization rate corresponding to the target cell, the base station can determine the bandwidth range corresponding to the target cell according to the target RB utilization rate.

Specifically, the base station may determine a target utilization rate range corresponding to the target RB utilization rate according to the obtained target RB utilization rate, and then adjust a bandwidth range corresponding to the target cell according to a target bandwidth range corresponding to the target utilization rate range.

For example, different utilization ranges and bandwidth ranges corresponding to the different utilization ranges may be configured in advance for the base station.

For example, the correspondence relationship shown in table 1 below may be set so that the base station configures different bandwidth ranges for cells of different RB utilization.

TABLE 1

Utilization range	Bandwidth range
		RB utilization rate<20％	CSI-RS-RB and SRS-RB are 40% of the cell system bandwidth
RB utilization rate of 20% or less<40％	CSI-RS-RB and SRS-RB are 60% of the cell system bandwidth
		RB utilization rate of 40% or less<60％	CSI-RS-RB and SRS-RB are 80% of the cell system bandwidth
RB utilization rate of 60% or less	CSI-RS-RB and SRS-RB are 100% of the cell system bandwidth

Thus, when the base station obtains the target RB utilization rate corresponding to the target cell, the bandwidth range corresponding to the target cell can be adjusted according to the matching relation between the target RB utilization rate, the utilization rate range and the bandwidth range. And after the bandwidth range corresponding to the target cell is adjusted according to the corresponding target RB utilization rate, the resource transmission of the base station to the target cell can occupy different bandwidth ranges according to actual needs, so that the transmission of the CSI-RS and the detection of the SRS are reduced, and the energy consumption of the base station is reduced. For example, when the bandwidth range of the target cell is correspondingly adjusted to 40%, the time slot in which the base station needs to transmit the CSI-RS becomes 40% of the full-period time slot, in other words, after adjustment, the base station only needs to correspondingly transmit the CSI-RS resource in 40% of the time slot, so that the base station can further reduce the energy consumption required by itself compared with the full-period transmission.

It should be noted that the specific values in table 1 are merely examples, and in the practical application process, specific data of the bandwidth range may be determined according to the use requirement, which is not limited in this application.

The above describes the procedure of adjusting the bandwidth range for the cell by the base station, and when the cell is activated, the base station can configure the bandwidth range corresponding to the cell to be the full bandwidth, so as to ensure that CRI-RS transmission and SRS detection are performed normally.

For example, in the 100M NR cell shown in fig. 7, when the full bandwidth resource position of the CSI-RS of the cell is configured, assuming that the period of CSI-RS transmission is slot20 and the initial time domain is slot5, the CSI-RS may be deployed in the RB range corresponding to the full bandwidth of the cell in the time domains slot5, slot25, slot45 … slot105 … slot n.

As shown in fig. 8, in the 100M NR cell, when the full bandwidth resource position of the cell SRS is configured, if the period of the base station for detecting the SRS is slot10 and the initial time domain is slot9, then the SRS may be deployed in the RB range corresponding to the full bandwidth of the cell in the time domain slot 9slot 19slot29 … slot105 … slot n.

The above description describes a manner in which the base station adjusts the bandwidth range corresponding to the target cell based on the target RB utilization corresponding to the target cell, and in the specific implementation process, the base station may further implement continuous adaptive adjustment of the bandwidth range in the following manner.

Referring to fig. 9, a flowchart of a method for adjusting a bandwidth range of a target cell according to an embodiment of the present application is shown in fig. 9, and the method specifically includes the following implementation steps:

step S901: and acquiring the real-time RB utilization rate corresponding to the target cell at fixed time.

The base station can obtain the real-time RB utilization rate corresponding to the target cell at a specified time point according to a preset time range, or can periodically obtain the real-time RB utilization rate corresponding to the target cell according to a preset time interval, and the specific numerical value of the real-time RB utilization rate is not limited in the application.

After each acquisition of the real-time RB utilization of the target cell, the base station may continue to perform the following operations:

step S902: acquiring a utilization ratio difference value between a real-time RB utilization ratio and a historical RB utilization ratio, wherein the historical RB utilization ratio is as follows: and determining the corresponding target RB utilization rate when the bandwidth range of the target cell is in the current moment.

After the base station obtains the real-time RB utilization rate corresponding to the target cell at the current moment, the base station can utilize the real-time RB utilization rate to obtain the utilization rate difference value between the historical RB utilization rates corresponding to the bandwidth range of the target cell at the current moment.

It should be understood that, in the manner shown in fig. 6, the base station determines the corresponding utilization range based on the target RB utilization and determines the corresponding bandwidth range, so that, correspondingly, the base station may determine the corresponding historical RB utilization by using the bandwidth range corresponding to the target cell at the current moment, and further determine the utilization difference between the real-time RB utilization and the historical RB utilization.

Step S903: judging whether the utilization rate difference is larger than a preset difference threshold; if yes, go to step S904; if not, continuing to acquire the real-time RB utilization rate corresponding to the target cell, namely continuing to execute step S901.

Step S904: based on the real-time RB utilization, a corresponding bandwidth range of the target cell is adjusted.

For a target cell, the base station continuously and regularly acquires the RB utilization rate of the target cell, and the RB utilization rate shows a certain fluctuation trend. For example, in table 1, 20% is a threshold between two utilization ranges, and the RB utilization of the target cell may change back and forth between 20% with a small amplitude, so as to avoid the occurrence of the situation that the base station frequently changes the bandwidth range of the target cell due to frequent small amplitude fluctuation of the RB utilization, it is proposed in the above step that the base station needs to determine whether the difference in utilization is greater than a preset difference threshold.

And only when the utilization ratio difference is larger than the difference threshold, the base station starts to trigger RRC reconfiguration of the online UE aiming at the target cell based on the real-time RB utilization ratio of the current moment of the target cell, and adjusts the bandwidth range corresponding to the target cell. And when the utilization ratio difference is not greater than the difference threshold, the base station does not correspondingly adjust the bandwidth range of the target cell.

Therefore, after confirming that the RB utilization rate of the cell has large change, the base station can adjust the bandwidth range of the cell, so that the base station can adaptively adjust the bandwidth range of the cell according to the load condition of the cell, and can also ensure that the adjustment action is kept in a certain frequency range, and the energy consumption of the base station is in an ideal state.

Alternatively, when the base station adjusts the bandwidth range of the target cell, the following operations may be optionally performed.

First, it is determined whether the utilization ranges of the real-time RB utilization and the historical RB utilization acquired in step S901 are the same.

When the real-time RB utilization rate and the historical RB utilization rate are determined to be different in the utilization rate ranges, the fact that the RB utilization rate of the target cell has larger changes at the moment is indicated, and the changes of the RB utilization rate span different utilization rate ranges is indicated, so that the base station can adjust the bandwidth range corresponding to the target cell based on the real-time RB utilization rate.

When the real-time RB utilization rate and the historical RB utilization rate are determined to be the same in the respective corresponding utilization rate ranges, it is indicated that the RB utilization rate of the target cell is greatly changed at this time, but the change is in the same utilization rate range (for example, the RB utilization rate is changed from 23% to 33%), then at this time, the base station may update the value of the historical RB utilization rate corresponding to the bandwidth range of the current time of the target cell based on the real-time RB utilization rate, so that when the subsequent base station acquires the new real-time RB utilization rate again, the subsequent base station may compare the new real-time RB utilization rate with the updated historical RB utilization rate and continue the subsequent judgment.

For example, assuming that the historical RB utilization corresponding to the target cell is 23% and the real-time RB utilization is 33%, when the base station determines that the utilization ranges corresponding to the two utilization ratios are the same, the base station may update the value of the historical RB utilization to 33% for subsequent use in comparison again according to the new real-time RB utilization.

Therefore, the base station selects whether to adjust the bandwidth range corresponding to the target cell according to whether the real-time RB utilization rate and the historical RB utilization rate are the same or not, so that the bandwidth range adjustment can be smoothly performed when the RB utilization rate changes across the utilization rate range, the change of the RB utilization rate can be accumulatively perceived by the base station, the adjustment of the bandwidth range of the target cell by the base station is more stable and is close to the change condition of the cell load, and the feasibility of the scheme is improved.
