When multiple wireless systems coexist, a spectrum sharing technique may be employed to fully utilize the bandwidth and improve the spectrum utilization efficiency. According to the size relationship between NR (New Radio, New air interface) and LTE (Long Term Evolution) available bandwidths, spectrum sharing is divided into two ways: one is full shared spectrum, i.e. NR and LTE maximum available bandwidths are the same, e.g. both 20MHz bandwidths; the other is a partially shared spectrum, i.e. the NR maximum available bandwidth is larger than the LTE maximum available bandwidth, for example, NR occupies 100MHz bandwidth, and LTE occupies 20MHz bandwidth.

The following describes in detail a method, a device, an apparatus, and a storage medium for allocating spectrum shared resources according to an embodiment of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

In the related art, when resources used by NR and resources used by LTE are determined in a shared frequency band, available resources are determined only according to information such as network load or resource utilization conditions, interference, service characteristics, and user characteristics.

Actually, when determining the shared resource, if the shared resource is determined only according to the above information or resource utilization, if the LTE uplink data reception is detected incorrectly, because the corresponding subframe of the next radio frame is shared by another network or the shared bandwidth in the corresponding subframe is too small, the LTE non-adaptive retransmission cannot be performed, and only the LTE adaptive retransmission is used, and in the case of the adaptive retransmission, the network side needs to configure the resource, so the retransmission delay is increased, and in addition, a scheduling PDCCH (Physical Downlink Control Channel) is also transmitted, which increases the resource overhead and interference.

In addition, if the shared resources are determined only according to the information or the resource utilization conditions, and there are situations such as arrival of new uplink or downlink services, random access, and sending of handover commands, the situations that the services cannot be scheduled in time, the random access delay is increased, and handover cannot be performed in time due to lack of available shared resources or too small shared bandwidth occur, which brings about a decrease in user experience and network KPI (Key Performance Indicator).

In order to solve or at least partially solve the above problem, embodiments of the present application provide a method for allocating spectrum shared resources.

Fig. 1 is a schematic flowchart of a method for allocating spectrum shared resources according to an embodiment of the present application, where an execution subject of the method may be a network device, as shown in fig. 1, the method includes the following steps:

step 100, under the condition that a new air interface NR network and a long term evolution LTE network adopt a time division multiplexing mode TDD part to share LTE frequency band resources, performing uplink sharing judgment based on the current period uplink actual physical resource block PRB resource utilization rate and an uplink data detection result, performing downlink sharing judgment based on the downlink actual PRB resource utilization rate and the uplink sharing result, and determining the next period NR actual available subframe position and the LTE actual available subframe position;

and/or the presence of a gas in the gas,

Specifically, for the shared resource allocation in the TDD partial spectrum sharing mode, NR has a dedicated bandwidth, and NR available bandwidth is greater than LTE available bandwidth, so an LTE absolute priority policy is mainly considered. And NR and LTE share LTE frequency band resources in a time division multiplexing mode. Allocation of shared resources requires determination of NR available subframe locations and LTE available subframe locations.

When shared resources are determined in a TDD partial frequency spectrum sharing mode, a method for performing uplink sharing judgment based on the current period uplink actual Physical Resource Block (PRB) resource utilization rate and an uplink data detection result and performing downlink sharing judgment based on the downlink actual PRB resource utilization rate and the uplink sharing result is adopted, the position of the next period NR actual usable subframe and the position of the LTE actual usable subframe are determined, the loss of LTE non-adaptive retransmission performance caused by bandwidth sharing is avoided, and the LTE performance is ensured.

In an optional embodiment, first, relevant parameter initialization and statistics of the Resource utilization rate of an LTE actual PRB (Physical Resource Block) and the number of LTE available subframes in a sharing judgment period are performed, then, the number of LTE available subframes and the maximum NR available subframe in a next period are determined according to a relevant sharing judgment method, and a position of an NR actual available subframe and a position of an LTE actual available subframe are determined.

For resource allocation in FDD full spectrum sharing, the NR available bandwidth is equal to the LTE available bandwidth, so NR and LTE equal priority policies are mainly considered. And NR and LTE share LTE frequency band resources in a frequency division multiplexing mode. The shared resource allocation method needs to determine the NR available bandwidth size and the LTE available bandwidth size.

In the frequency division multiplexing mode, in each subframe in a set period, the available bandwidth of the LTE is fixed, so the LTE does not have the problem of non-adaptive retransmission, and the problem of non-adaptive retransmission possibly exists only after the bandwidth is shared between the periods and adjusted. The scheme adopts a larger period to reduce the probability of the problem that the non-adaptive retransmission cannot be realized. In addition, the adjustment of the shared bandwidth in the period is only carried out according to the set step length, so that the problem that the LTE cannot adopt a self-adaptive retransmission mode for retransmission due to the fact that the adjustment of the shared bandwidth is too large is avoided, and the retransmission performance of the LTE is guaranteed.

When sharing resources are allocated in an FDD complete frequency spectrum sharing mode, a method for carrying out sharing judgment based on an actual PRB resource utilization ratio and a to-be-transmitted data volume ratio is adopted, and NR and LTE fair sharing resources are guaranteed.

In an optional embodiment, the method includes initializing relevant parameters, performing sharing judgment on a ratio of an LTE actual PRB resource utilization rate to an NR actual PRB resource utilization rate and a ratio of an LTE to-be-transmitted data amount to an NR to-be-transmitted data amount in a cycle, determining an LTE available bandwidth and an NR available bandwidth in a next cycle according to a relevant sharing judgment method, and then adjusting and maintaining shared resources.

Optionally, as shown in fig. 2, the determining the actual usable subframe position of NR and the actual usable subframe position of LTE in the next period based on performing uplink sharing determination based on the actual resource utilization of the uplink physical resource block PRB in the current period and the uplink data detection result and performing downlink sharing determination based on the actual resource utilization of the downlink PRB and the uplink sharing result further includes:

1001, determining the number of LTE uplink/downlink available subframes in the next period according to the actual utilization rate of the LTE uplink/downlink PRB resources and the actual number of the LTE uplink/downlink available subframes in the current period;

step 1002, determining the maximum uplink/downlink available subframe number of the next period NR according to all uplink/downlink subframe numbers in one period and the uplink/downlink available subframe number of the next period LTE;

step 1003, determining the actual available sub-frame position of the NR uplink and the actual available sub-frame position of the LTE uplink based on the number of the maximum uplink available sub-frames of the next period NR, the detection result of the LTE uplink data, the presence identifier of the VoLTE service carried by the long-term evolution voice, and the configuration information of the SRS resource pool of the LTE sounding reference signal;

step 1004, determining the position of the NR downlink actually usable subframe and the position of the LTE downlink actually usable subframe based on the number of the NR maximum downlink usable subframes in the next period, the position of the LTE uplink actually usable subframe, the VoLTE service existence flag, and the configuration information of the LTE system information block SIB 1.

Specifically, the number of LTE uplink/downlink available subframes in the next period is determined according to the actual utilization rate of LTE uplink/downlink PRB resources and the actual number of LTE uplink/downlink available subframes in the current period.

After the number of the LTE uplink/downlink available subframes in the next period is determined, the NR maximum available subframe number in the next period is the number of the remaining subframes obtained by subtracting the number of the LTE uplink/downlink available subframes in the next period from the number of all uplink/downlink subframes in the period.

Then, in the uplink direction, the position of the NR uplink actually usable subframe and the position of the LTE uplink actually usable subframe need to be determined based on the information such as the number of the next-period NR maximum uplink usable subframes, the LTE uplink data detection result, the presence of the Voice over Long-Term Evolution (VoLTE) service identifier, the LTE SRS (Sounding reference signal) resource pool configuration, and the like.

In the downlink direction, the position of the NR downlink actually-usable subframe and the position of the LTE downlink actually-usable subframe need to be determined based on the information such as the number of the NR maximum downlink usable subframes in the next period, the position of the LTE uplink actually-usable subframe, the VoLTE service presence identifier, the LTE SIB1(system information block type 1) transmission configuration, and the like.

In the embodiment of the application, aiming at the problem that the data reception detection of the LTE in the uplink direction is wrong in a time division multiplexing mode, and the corresponding subframe of the next radio frame is shared by another network, so that the LTE data cannot be subjected to non-adaptive retransmission, when the shared resource is determined, a method for performing uplink sharing judgment based on the information such as the uplink actual PRB resource utilization rate and the uplink data detection result and a method for performing downlink sharing judgment based on the information such as the downlink actual PRB resource utilization rate and the uplink sharing result are adopted, so that the loss of the non-adaptive retransmission performance of the LTE caused by bandwidth sharing is avoided, the LTE performance is ensured, and the uplink and downlink sharing linkage factors are considered.

Optionally, in step 1001, the number of LTE uplink/downlink available subframes in the next period is determined according to the actual LTE uplink/downlink PRB resource utilization rate and the actual LTE uplink/downlink available subframe in the current period, where the determining includes one of the following:

specifically, if the number of actually available subframes of LTE in the current period is 0, in order to quickly recover the LTE service, the actual PRB resource utilization rate needs to be initialized to 0, and the principle is applicable to uplink and downlink;

if the data to be scheduled exists, the number of the LTE available subframes in the next period is at least 1, and the principle is suitable for uplink and downlink;

Specifically, the embodiment of the application also considers the influence of factors such as the arrival of new uplink or downlink services, random access, sending of switching commands and the like when determining shared resources, so that the shared random access performance and switching performance are ensured, and the user experience and the reduction of network KPI are avoided.

When receiving and detecting a Physical Random Access Channel (PRACH) in the LTE network, the shared resource adjustment caused by the Random Access is triggered. In order to ensure the random access performance, all the shared subframes are adjusted to LTE-available subframes within a set time (e.g. from the reception of PRACH until the completion of the random access procedure). This principle applies to both upstream and downstream.

When user switching exists in the LTE network, a switching command needs to be sent, and shared resource adjustment brought by switching is triggered. In order to ensure the switching performance, all the shared downlink subframes are adjusted to LTE downlink available subframes within a set time. This principle only applies to the downlink.

When an uplink in the LTE network receives a service SR request, shared resource adjustment brought by SR is triggered.

(5) When the uplink in the LTE network receives the service SR request and the available bandwidth of the LTE uplink is less than the number of PRBs required for setting the LTE uplink SR, the shared resource adjustment brought by the SR is triggered.

In order to guarantee the user service experience, the available bandwidth of LTE/NR will be adjusted according to the similar principle in (1) within a set time (e.g. from SR transmission to BSR successful reception).

(6) When the uplink in the NR network receives the service SR request and the available bandwidth of the NR uplink is less than the number of PRBs required by the set NR uplink SR, the shared resource adjustment brought by the SR is triggered.

In order to guarantee the user service experience, the available bandwidth of LTE/NR will be adjusted according to the similar principle in (2) within a set time (e.g. from SR transmission to BSR successful reception).

(7) When the VoLTE service exists in the LTE network, and the current available bandwidth of the LTE downlink is less than the number of PRBs required for setting the VoLTE downlink (for example, 50% of the full bandwidth) or the available bandwidth of the LTE uplink is less than the number of PRBs required for setting the VoLTE uplink (for example, 50% of the full bandwidth), in order to ensure the quality of the voice service, the available bandwidth of the LTE/NR is adjusted according to the similar principle in (1) within a set time (for example, from the start of the VoLTE service to the end of the VoLTE service).

(8) When a Voice over New Radio (NR) service exists in the NR network, and the current NR downlink available bandwidth is less than the number of PRBs required for setting the VoNR downlink (e.g., 50% of the full bandwidth) or the NR uplink available bandwidth is less than the number of PRBs required for setting the VoNR uplink (e.g., 50% of the full bandwidth), in order to ensure the quality of the Voice service, the LTE/NR available bandwidth is adjusted according to the similar principle in (2) within a set time (e.g., from the start of the VoNR service to the end of the VoNR service).

(9) When a plurality of reasons are triggered simultaneously, MAX (the number of PRBs required for all reasons NR) is required to be set for NR, or MAX (the number of PRBs required for all reasons LTE) is required to be set for LTE.
