[0030] The following will combine the accompanying drawings and, through specific embodiments and their application scenarios, elaborate in detail on the spectrum sharing resource allocation method, device, apparatus, and storage medium provided by the embodiments of this application.

[0031] In the current related technologies, when determining the resources used by NR and the resources used by LTE within the shared frequency band, the available resources are determined only based on information such as network load, resource utilization, interference, service characteristics, and user characteristics.

[0032] Actually, when determining shared resources, if the shared resources are determined only based on the above information or resource utilization, in the case of LTE detecting an error in uplink data reception, since the corresponding subframe of the next radio frame is shared with other networks or the shared bandwidth within the corresponding subframe is too small, LTE non - adaptive retransmission cannot be performed and only LTE adaptive retransmission can be used. In the case of adaptive retransmission, the network side needs to configure resources, so the retransmission delay will increase. In addition, it is also necessary to send scheduling PDCCH (Physical Downlink Control Channel), which increases resource overhead and interference.

[0033] In addition, if the shared resources are determined only based on the above information or resource utilization, when there are situations such as the arrival of new uplink or downlink services, random access, and the sending of handover commands, due to the lack of available shared resources or the shared bandwidth being too small, the services cannot be scheduled in a timely manner, the random access delay increases, and the handover cannot be performed in a timely manner, resulting in a decline in user experience and network KPIs (Key Performance Indicators).

[0034] To solve or at least partially solve the above problems, the embodiments of the present application provide a method for allocating spectrum shared resources.

[0035] Figure 1 The following is a schematic flowchart of the method for allocating spectrum shared resources provided by the embodiments of the present application. The execution subject of this method can be a network device, such as Figure 1 As shown, the method includes the following steps:

[0036] Step 100: In the case where the new radio (NR) network and the long - term evolution (LTE) network partially share the LTE frequency band resources in a time - division duplex (TDD) manner, based on the actual physical resource block (PRB) resource utilization rate of the uplink in the current period and the uplink data detection result, perform uplink sharing judgment, and based on the actual PRB resource utilization rate of the downlink and the uplink sharing result, perform downlink sharing judgment to determine the positions of the actually available subframes of NR and LTE in the next period;

[0037] And / or,

[0038] In the case where the NR network and the LTE network fully share the LTE frequency band resources in a frequency - division duplex (FDD) manner, according to the ratio of the actual PRB resource utilization rate of LTE to the actual PRB resource utilization rate of NR in the current period, and the ratio of the LTE data to be transmitted to the NR data to be transmitted, determine the available bandwidth of LTE and the available bandwidth of NR in the next period.

[0039] Specifically, for the shared resource allocation in the TDD partial spectrum sharing mode, NR has dedicated bandwidth, and the available bandwidth of NR is greater than that of LTE. Therefore, the LTE absolute priority strategy is mainly considered. NR and LTE share the LTE frequency band resources in a time-division multiplexing manner. The allocation of shared resources needs to determine the available subframe positions of NR and LTE.

[0040] When determining the shared resources in the TDD partial spectrum sharing mode, a method is adopted to perform uplink sharing judgment based on the actual physical resource block (PRB) resource utilization rate of the uplink in the current period and the uplink data detection result, and perform downlink sharing judgment based on the actual PRB resource utilization rate of the downlink and the uplink sharing result, so as to determine the actual available subframe positions of NR and LTE in the next period, avoiding the loss of LTE non-adaptive retransmission performance caused by bandwidth sharing and ensuring the LTE performance.

[0041] In an optional embodiment, first, relevant parameter initialization and the statistics of the actual PRB (Physical Resource Block) resource utilization rate of LTE and the available number of LTE subframes within the sharing judgment period are performed. Then, according to the relevant sharing judgment method, the available number of LTE subframes and the maximum available number of NR subframes in the next period are determined, as well as the actual available subframe positions of NR and LTE are determined.

[0042] For the shared resource allocation in the FDD full spectrum sharing mode, the available bandwidth of NR is equal to that of LTE. Therefore, the equal priority strategy of NR and LTE is mainly considered. NR and LTE share the LTE frequency band resources in a frequency-division multiplexing manner. The shared resource allocation method needs to determine the size of the available bandwidth of NR and LTE.

[0043] In the frequency-division multiplexing mode, the available bandwidth of LTE exists fixedly in each subframe within the set period. Therefore, there is no problem that LTE cannot perform non-adaptive retransmission. Only after the bandwidth sharing is adjusted between periods, there may be a problem that non-adaptive retransmission cannot be performed. In the solution, a larger period is set to reduce the probability of the occurrence of the problem of non-adaptive retransmission. In addition, when adjusting the shared bandwidth between periods, it is only performed according to the set step size, avoiding the problem that LTE cannot perform retransmission in an adaptive retransmission manner due to excessive adjustment of the shared bandwidth, thereby ensuring the retransmission performance of LTE.

[0044] When performing shared resource allocation in the FDD full spectrum sharing mode, a method based on the ratio of the actual PRB resource utilization rate and the ratio of the data volume to be transmitted is adopted for sharing judgment to ensure fair sharing of resources between NR and LTE.

[0045] In an optional embodiment, first, relevant parameters are initialized, and the ratios of the actual LTE PRB resource utilization rate to the actual NR PRB resource utilization rate and the ratio of the LTE data to be transmitted to the NR data to be transmitted during the sharing judgment period are calculated. Then, according to relevant sharing judgment methods, the available bandwidth of LTE and the available bandwidth of NR in the next period are determined. After that, the adjustment and maintenance of shared resources are carried out.

[0046] In the embodiments of the present application, methods for determining the resources used by NR and the resources used by LTE in the shared frequency band under the LTE absolute priority strategy of partial spectrum sharing mode and methods for determining the resources used by NR and the resources used by LTE in the shared frequency band under the equal priority strategy of NR and LTE in the full spectrum sharing mode are given, which can reduce the loss of LTE retransmission performance caused by bandwidth sharing and ensure LTE performance.

[0047] Optionally, as Figure 2 shown, the method for performing uplink sharing judgment based on the actual physical resource block (PRB) resource utilization rate of the uplink in the current period and the uplink data detection result and the method for performing downlink sharing judgment based on the actual PRB resource utilization rate of the downlink and the uplink sharing result to determine the actual available subframe positions of NR and LTE in the next period further include:

[0048] Step 1001: Determine the available subframe numbers of the LTE uplink / downlink in the next period according to the actual LTE uplink / downlink PRB resource utilization rate and the actual available subframe numbers of the LTE uplink / downlink in the current period;

[0049] Step 1002: Determine the maximum available subframe numbers of the NR uplink / downlink in the next period according to the total number of uplink / downlink subframes in one period and the available subframe numbers of the LTE uplink / downlink in the next period;

[0050] Step 1003: Based on the maximum available subframe numbers of the NR uplink in the next period, the LTE uplink data detection result, the presence flag of the Voice over LTE (VoLTE) service, and the configuration information of the LTE sounding reference signal (SRS) resource pool, determine the actual available subframe positions of the NR uplink and the LTE uplink;

[0051] Step 1004: Based on the maximum available subframe numbers of the NR downlink in the next period, the actual available subframe positions of the LTE uplink, the presence flag of the VoLTE service, and the configuration information of the LTE system information block (SIB1), determine the actual available subframe positions of the NR downlink and the LTE downlink.

[0052] Specifically, first, the available subframe numbers of the LTE uplink / downlink in the next period are determined according to the actual LTE uplink / downlink PRB resource utilization rate and the actual available subframe numbers of the LTE uplink / downlink in the current period.

[0053] After determining the available subframe numbers of LTE uplink / downlink in the next period, the maximum available subframe numbers of NR in the next period are the remaining subframe numbers after subtracting the available subframe numbers of LTE uplink / downlink in the next period from all uplink / downlink subframe numbers in the period.

[0054] Then, in the uplink direction, it is necessary to determine the actual available subframe positions of NR uplink and LTE uplink based on information such as the maximum available uplink subframe numbers of NR in the next period, LTE uplink data detection results, the presence indication of VoLTE (Voice over Long-Term Evolution) service, and the configuration of LTE SRS (Sounding reference signal) resource pool.

[0055] In the downlink direction, it is necessary to determine the actual available subframe positions of NR downlink and LTE downlink based on information such as the maximum available downlink subframe numbers of NR in the next period, the actual available subframe positions of LTE uplink, the presence indication of VoLTE service, and the transmission configuration of LTE SIB1 (system information block type1).

[0056] In the embodiment of the present application, for the problem that in the time division multiplexing mode, the data reception detection of LTE in the uplink direction is incorrect, and the corresponding subframes of the next radio frame are shared with other networks, resulting in the inability of LTE data to perform non-adaptive retransmission, in the embodiment of the present application, when determining the shared resources, an uplink sharing judgment method based on information such as the actual PRB resource utilization rate of the uplink and the uplink data detection results and a downlink sharing judgment method based on information such as the actual PRB resource utilization rate of the downlink and the uplink sharing result are adopted, which avoids the loss of LTE non-adaptive retransmission performance caused by bandwidth sharing, ensures the LTE performance, and at the same time considers the uplink and downlink sharing linkage factors.

[0057] Optionally, the step 1001 of determining the available subframe numbers of LTE uplink / downlink in the next period according to the actual PRB resource utilization rate and the actual available subframe numbers of LTE uplink / downlink in the current period includes one of the following items:

[0058] (1) When there is a VoLTE service in the LTE network, determining the available subframe numbers of LTE uplink / downlink in the next period as all uplink / downlink subframe numbers in the next period;

[0059] When there is a VoLTE service in the LTE network, in order to ensure the quality of voice services, the available subframe numbers of LTE in the next period are all subframes in the next period, and this principle applies to both uplink and downlink.

[0060] (2) When the actual available sub - frame number of LTE uplink / downlink in the current period is zero, and there is data to be scheduled or an uplink service scheduling request SR is received, it is determined that the available sub - frame number of LTE in the next period is at least 1; otherwise, the available sub - frame number of LTE uplink / downlink in the next period remains 0.

[0061] Specifically, if the actual available sub - frame number of LTE in the current period is 0, in order to quickly resume LTE services, it is necessary to initialize the actual PRB resource utilization rate to 0, and this principle applies to both the uplink and the downlink.

[0062] If there is data to be scheduled, then the available sub - frame number of LTE in the next period is at least 1, and this principle applies to both the uplink and the downlink.

[0063] For the uplink direction, if an uplink service SR request is received, then the available sub - frame number of LTE uplink in the subsequent two consecutive periods is at least 1.

[0064] In other cases, the available sub - frame number of LTE in the next period is not adjusted and remains 0.

[0065] (3) When the actual available sub - frame number of LTE uplink / downlink in the current period is 1, and the actual PRB resource utilization rate of LTE uplink / downlink is less than the first preset threshold, if there is no data to be scheduled, it is determined that the available sub - frame number of LTE uplink / downlink in the next period is 0; otherwise, the available sub - frame number of LTE uplink / downlink in the next period remains 1.

[0066] It should be noted that the first preset threshold is the set low threshold of the PRB resource utilization rate.

[0067] (4) When the actual available sub - frame number of LTE uplink / downlink in the current period is greater than 1, and the actual PRB resource utilization rate of LTE uplink / downlink is less than the first preset threshold, based on the smoothed actual PRB resource utilization rate of LTE uplink / downlink and the second preset threshold, calculate the required uplink / downlink sub - frame number of LTE, and determine the available sub - frame number of LTE uplink / downlink in the next period according to the relative relationship between the smoothed actual available sub - frame number of LTE uplink / downlink and the required uplink / downlink sub - frame number of LTE.

[0068] Optionally, the calculating the required uplink / downlink sub - frame number of LTE based on the smoothed actual PRB resource utilization rate of LTE uplink / downlink and the second preset threshold includes:

[0069] Use the following formula to calculate the required uplink sub - frame number of LTE:

[0070]

[0071] Among them, SFNumEstimate LTE_ul is the number of uplink subframes required for LTE, and PRBUsage LTE_ul is the actual uplink PRB resource utilization rate after smoothing filtering. PRBUsageHighThr is the second preset threshold, and SFNumPerPeriod ul is the total number of uplink subframes within a period;

[0072] The number of downlink subframes required for LTE is calculated using the following formula:

[0073]

[0074] Among them, SFNumEstimate LTE_dl is the number of downlink subframes required for LTE, and PRBUsage LTE_dl is the actual downlink PRB resource utilization rate after smoothing filtering. PRBUsageHighThr is the second preset threshold, and SFNumPerPeriod dl is the total number of downlink subframes within a period.

[0075] It should be noted that the second preset threshold is the set high threshold of PRB resource utilization rate.

[0076] Optionally, determining the available number of LTE uplink / downlink subframes in the next period according to the relative relationship between the actually available number of LTE uplink / downlink subframes after smoothing filtering and the required number of LTE uplink / downlink subframes includes:

[0077] Calculating the available number of LTE uplink subframes in the next period according to the actually available number of LTE uplink subframes after smoothing filtering and the required number of LTE uplink subframes using the following formula:

[0078]

[0079] Among them, SFNumNext LTE_ul is the available number of LTE uplink subframes in the next period, SFNumStatic LTE_ul is the actually available number of LTE uplink subframes after smoothing filtering, and SFNumEstimate LTE_ul is the required number of LTE uplink subframes, where X is the set reduction step and Y is the set increase multiple;

[0080] Calculating the available number of LTE downlink subframes in the next period according to the actually available number of LTE downlink subframes after smoothing filtering and the required number of LTE downlink subframes using the following formula:

[0081]

[0082] Among them, SFNumNext LTE_dl is the number of available subframes for LTE downlink in the next period, and SFNumStatic LTE_dl is the actual number of available subframes for LTE downlink after smoothing filtering, and SFNumEstimate LTE_dl is the number of downlink subframes required by LTE. Among them, X is the set reduction step, and Y is the set increase multiple.

[0083] (5) When the actual number of available subframes for LTE uplink / downlink in the current period is greater than zero and the actual PRB resource utilization rate of LTE uplink / downlink is greater than the second preset threshold, determine that the number of available subframes for LTE uplink / downlink in the next period is all the uplink / downlink subframes in the next period.

[0084] (6) When the actual number of available subframes for LTE uplink / downlink in the current period is greater than zero and the actual PRB resource utilization rate of LTE uplink / downlink is between the first preset threshold and the second preset threshold, determine that the number of available subframes for LTE uplink / downlink in the next period is the actual number of available subframes for LTE uplink / downlink in the current period after smoothing filtering.

[0085] Optionally, step 1003 determines the actual available subframe positions for NR uplink and LTE uplink based on the maximum available subframes for NR uplink in the next period, the LTE uplink data detection result, the presence flag of the Voice over LTE (VoLTE) service, and the configuration information of the LTE sounding reference signal (SRS) resource pool, and further includes:

[0086] In a period, traverse each uplink subframe position in sequence according to the order of received uplink subframes;

[0087] When the first preset condition is met, determine that the position of the target uplink subframe in the next radio frame is the actual available subframe position for NR uplink; otherwise, determine that the position of the target uplink subframe in the next radio frame is the actual available subframe position for LTE uplink;

[0088] Stop traversing until all uplink subframes in the period are traversed or the number of currently determined actual available subframe positions for NR uplink is equal to the maximum available subframes for NR uplink in the next period;

[0089] Among them, the meeting of the first preset condition includes:

[0093] The currently determined number of actually available subframe positions for NR uplink is less than the maximum number of available subframes for NR uplink in the next period;

[0094] The VoLTE service does not exist.

[0095] Specifically, in the uplink direction, it is necessary to determine the actually available subframe positions for NR uplink and the actually available subframe positions for LTE uplink based on information such as the maximum number of available subframes for NR uplink in the next period, the LTE uplink data detection result, the VoLTE service presence flag, and the LTE SRS resource pool configuration.

[0096] Within a period, traverse each uplink subframe position in sequence according to the order of received uplink subframes. Let the currently received radio frame SFN n and the uplink subframe sf m in it. If the following conditions are simultaneously met: (1) the data detection result of the uplink subframe sf m is ACK; (2) there is no configured transmission of LTE SRS resources in the next radio frame SFN n+1 ; (3) the currently determined number of actually available subframe positions for NR uplink is less than the maximum number of available subframes for NR uplink in the next period; (4) the VoLTE service does not exist, then determine that the position of the uplink subframe sf n+1 in the next radio frame SFN m is the actually available subframe position for NR uplink; otherwise, determine that the position of the uplink subframe sf n+1 in the next radio frame SFN m is the actually available subframe position for LTE uplink.

[0097] Until all uplink subframes in the period are traversed, or the currently determined number of actually available subframe positions for NR uplink is equal to the maximum number of available subframes for NR uplink in the next period, exit the traversal process.

[0105] According to the frame structure configuration, the actually available LTE uplink subframe positions, and the scheduling timing, it is judged that the target downlink subframe does not need to send the physical downlink control channel PDCCH for scheduling uplink services on the scheduling timing, or, on the scheduling timing, the target downlink subframe needs to send the physical downlink control channel PDCCH for scheduling uplink services but the corresponding scheduled subframe position is not the actually available LTE uplink subframe position;

[0106] The currently determined number of actually available NR downlink subframe positions is less than the maximum number of available NR downlink subframes in the next period;

[0107] The VoLTE service does not exist.

[0108] Specifically, in the downlink direction, it is necessary to determine the actually available NR downlink subframe positions and the actually available LTE downlink subframe positions based on information such as the maximum number of available NR downlink subframes in the next period, the actually available LTE uplink subframe positions, the VoLTE service presence flag, and the LTE SIB1 transmission configuration.

[0109] Within the period, each downlink subframe position is traversed in sequence. Let the currently judged radio frame SFN n and the downlink subframe sf p . If the conditions are simultaneously satisfied: (1) The current downlink subframe does not need to send LTE SIB1 information, that is, the SFN is an odd frame, or, the SFN is an even frame but the downlink subframe number is not 5; (2) According to the frame structure configuration, the actually available LTE uplink subframe positions, and the scheduling timing, it is judged that: on the scheduling timing, this downlink subframe does not need to send LTE uplink PDCCH, or, on the scheduling timing, this downlink subframe needs to send the physical downlink control channel PDCCH for scheduling uplink services but the corresponding scheduled subframe position is not the actually available LTE uplink subframe position; (3) The currently determined number of actually available NR downlink subframe positions is less than the maximum number of available NR downlink subframes in the next period; (4) The VoLTE service does not exist, then it is determined that the downlink subframe sf n in the SFN p is the actually available NR downlink subframe position; otherwise, it is determined that the downlink subframe sf n in the SFN pThe position is the actual available subframe position for LTE downlink.

[0110] Exit the traversal process until all downlink subframes in the period are traversed, or the number of currently determined actual available subframe positions for NR downlink is equal to the maximum number of available downlink subframes for NR in the next period.

[0111] Optionally, after determining the actual available subframe position for NR in the next period and the actual available subframe position for LTE, it further includes:

[0112] Under the condition of meeting the third preset condition, adjust all shared subframes to LTE available subframes within a preset time;

[0113] After the preset time expires, restore the original shared resource configuration;

[0114] Wherein, the third preset condition includes at least one of the following:

[0115] Physical Random Access Channel (PRACH) is detected in the LTE network;

[0116] There is a user handover in the LTE network;

[0117] Scheduling Request (SR) is received in the LTE network.

[0118] Specifically, when determining shared resources in the embodiments of the present application, the impacts of factors such as the arrival of new uplink or downlink services, random access, and handover command sending are also considered to ensure the random access performance and handover performance after sharing, and avoid the degradation of user experience and network KPIs.

[0119] When PRACH (Physical Random Access Channel) is detected in the LTE network, it will trigger the adjustment of shared resources brought by random access. To ensure the random access performance, within a set time (such as before the random access process is completed after receiving PRACH), all shared subframes will be adjusted to LTE available subframes. This principle applies to both uplink and downlink.

[0120] When there is a user handover in the LTE network and a handover command needs to be sent, it will trigger the adjustment of shared resources brought by handover. To ensure the handover performance, within a set time, all shared downlink subframes will be adjusted to LTE downlink available subframes. This principle only applies to downlink.

[0121] When the uplink in the LTE network receives a service SR request, it will trigger the adjustment of shared resources brought by SR. To ensure the user experience, within a set time, all shared subframes will be adjusted to LTE available subframes. This principle applies to both uplink and downlink.

[0122] After the set timeouts, the original shared resource allocation will be restored.

[0123] In the embodiments of the present application, for the problem that in the time division multiplexing mode, the LTE data reception detection is incorrect in the uplink direction, and the corresponding subframe of the next radio frame is shared with other networks, resulting in the inability of LTE data to perform non - adaptive retransmission, in the solution, when determining the shared resources, a method for judging uplink sharing based on information such as the actual PRB resource utilization rate in the uplink and the uplink data detection result, and a method for judging downlink sharing based on information such as the actual PRB resource utilization rate in the downlink and the uplink sharing result are adopted, avoiding the loss of LTE non - adaptive retransmission performance caused by bandwidth sharing and ensuring the LTE performance. In addition, when determining the shared resources, the solution also considers the influence of factors such as the arrival of new services in the uplink or downlink, random access, and handover command sending, ensuring the random access performance and handover performance after sharing and avoiding the decline of user experience and network KPIs.

[0132] According to the target shared bandwidth ratio, the current NR available bandwidth, the current LTE available bandwidth, the ping-pong protection threshold for shared bandwidth adjustment, and the preset maximum single adjustment step size, use the following formula to determine the number of LTE shared bandwidth adjustment PRBs:

[0133]

[0135] According to the target shared bandwidth ratio, the current NR available bandwidth, the current LTE available bandwidth, the ping-pong protection threshold for shared bandwidth adjustment, and the preset maximum single adjustment step size, use the following formula to determine the number of NR shared bandwidth adjustment PRBs:

[0136]

[0137] where LTE_Prbnum_current is the current LTE available bandwidth, NR_Prbnum_current is the current NR available bandwidth, Adjust_guard is the ping-pong protection threshold for shared bandwidth adjustment, Adjust_step is the preset maximum single adjustment step size, and NR_X_Prbnum is the number of NR shared bandwidth adjustment PRBs.

[0138] Step 2003: Determine the next-cycle NR / LTE available bandwidth according to the number of available PRBs on the fully shared bandwidth, the current NR / LTE available bandwidth, and the number of NR / LTE shared bandwidth adjustment PRBs.

[0139] Optionally, determining the available bandwidth of NR / LTE in the next period according to the number of available PRBs on the fully shared bandwidth, the current available bandwidth of NR / LTE, and the adjusted PRB number of the NR / LTE shared bandwidth includes:

[0140] Adjust the number of PRBs according to the number of available PRBs on the fully shared bandwidth, the current available bandwidth of NR, and the adjusted PRB number of the NR shared bandwidth, and use the following formula to determine the available bandwidth of NR in the next period:

[0141] NR_Prbnum_next = max(min(NR_Prbnum_current + NR_X_Prbnum, All_Prbnum_init), 0)

[0142] Wherein, NR_Prbnum_next is the available bandwidth of NR in the next period, All_Prbnum_init is the number of available PRBs on the fully shared bandwidth, NR_Prbnum_current is the current available bandwidth of NR, and NR_X_Prbnum is the adjusted PRB number of the NR shared bandwidth;

[0143] According to the number of available PRBs on the fully shared bandwidth and the available bandwidth of NR, use the following formula to determine the available bandwidth of LTE in the next period:

[0144] LTE_Prbnum_next = All_Prbnum_init - NR_Prbnum_next

[0145] Wherein, LTE_Prbnum_next is the available bandwidth of LTE in the next period.

[0146] When allocating shared resources in the FDD full-spectrum sharing mode, the spectrum sharing resource allocation method provided by the embodiments of the present application determines the target shared bandwidth ratio according to the ratio of the actual number of used PRBs of NR and LTE and the ratio of the data volume to be transmitted, and determines the available bandwidth of NR / LTE by adjusting the number of PRBs according to the number of available PRBs on the fully shared bandwidth, the current available bandwidth of NR / LTE, and the adjusted PRB number of the NR / LTE shared bandwidth, which can reduce the loss of LTE retransmission performance caused by bandwidth sharing and ensure the performance of LTE.

[0147] Optionally, after determining the available bandwidth of LTE and NR in the next period, it further includes:

[0148] When the fourth preset condition is satisfied, adjust the available bandwidth of LTE to the maximum within a preset time;

[0149] When the fifth preset condition is satisfied, adjust the available bandwidth of NR to the maximum within a preset time;

[0150] After the preset timeouts, restore the original shared resource configuration;

[0151] Among them, the fourth preset condition includes at least one of the following:

[0152] A Physical Random Access Channel (PRACH) is detected within the LTE network, and the current available LTE bandwidth is less than the number of Physical Resource Blocks (PRBs) required for LTE random access;

[0153] There is a user handover within the LTE network, and the current available LTE bandwidth is less than the number of PRBs required for LTE handover;

[0154] A Scheduling Request (SR) is received uplink within the LTE network, and the current available LTE uplink bandwidth is less than the number of PRBs required for LTE uplink SR;

[0159] A Scheduling Request (SR) is received within the NR network, and the current available NR uplink bandwidth is less than the number of PRBs required for NR uplink SR;

[0160] There is a New Radio Voice Bearer (VoNR) service within the NR network, and the current available NR bandwidth is less than the number of PRBs required for the VoNR service.

[0161] Specifically, to ensure the performance of NR / LTE, it is necessary to trigger the adjustment of shared resources based on reasons such as random access, handover, uplink service SR requests, and voice services. LTE and NR need to interact on the reasons for triggering the sharing of resources, the number of PRBs that need to be guaranteed for the uplink, the number of PRBs that need to be guaranteed for the downlink, etc., including the following various situations:

[0162] (1) When a PRACH is detected and received within the LTE network, and the current available LTE downlink bandwidth is less than the set number of PRBs required for LTE random access downlink (such as 50% of the full bandwidth) or the current available LTE uplink bandwidth is less than the set number of PRBs required for LTE random access uplink, it will trigger the adjustment of shared resources brought about by random access.

[0163] To ensure the LTE random access performance, within a set time (e.g., from receiving the PRACH to the completion of the random access process), the available bandwidth of LTE / NR will be adjusted according to the following principles:

[0164] The available downlink bandwidth of LTE is adjusted to MAX(current available downlink bandwidth of LTE, the number of PRBs required for LTE downlink as set); the available downlink bandwidth of NR is adjusted to (total downlink bandwidth - available downlink bandwidth of LTE);

[0165] The available uplink bandwidth of LTE is adjusted to MAX(current available uplink bandwidth of LTE, the number of PRBs required for LTE uplink as set); the available uplink bandwidth of NR is adjusted to (total uplink bandwidth - available uplink bandwidth of LTE).

[0166] (2) When a PRACH is detected in the NR network and the current available downlink bandwidth of NR is less than the number of PRBs required for NR random access downlink as set (e.g., 50% of the total bandwidth) or the current available uplink bandwidth of NR is less than the number of PRBs required for NR random access uplink as set, the adjustment of shared resources caused by random access will be triggered.

[0167] To ensure the NR random access performance, within a set time (e.g., from receiving the PRACH to the completion of the random access process), the available bandwidth of LTE / NR will be adjusted according to the following principles:

[0168] The available downlink bandwidth of NR is adjusted to MAX(current available downlink bandwidth of NR, the number of PRBs required for NR downlink as set); the available uplink bandwidth of NR is adjusted to MAX(current available uplink bandwidth of NR, the number of PRBs required for NR uplink as set);

[0169] The available downlink bandwidth of LTE is adjusted to (total downlink bandwidth - available downlink bandwidth of NR); the available uplink bandwidth of LTE is adjusted to (total uplink bandwidth - available uplink bandwidth of NR).

[0170] (3) When there is a user handover in the LTE network and a handover command needs to be sent, and the current available downlink bandwidth of LTE is less than the number of PRBs required for LTE handover downlink as set (e.g., 50% of the total bandwidth) or the current available uplink bandwidth of LTE is less than the number of PRBs required for LTE handover uplink as set (e.g., 0), the adjustment of shared resources caused by handover will be triggered.

[0171] To ensure the handover performance, within a set time (e.g., from the sending of the handover command to the successful sending of the handover command), the available bandwidth of LTE / NR will be adjusted according to similar principles as in (1).

[0172] (4) When there is a user handover in the NR network and a handover command needs to be sent, and the current available NR downlink bandwidth is less than the set number of PRBs required for NR handover downlink (such as 50% of the full bandwidth) or the available NR uplink bandwidth is less than the set number of PRBs required for NR handover uplink (such as 0), the adjustment of shared resources brought about by the handover will be triggered.

[0173] To ensure handover performance, within a set time (such as from the sending of the handover command to the successful sending of the handover command), the available LTE / NR bandwidth will be adjusted according to the similar principle in (2).

[0174] (5) When an uplink service SR request is received in the LTE network and the available LTE uplink bandwidth is less than the set number of PRBs required for LTE uplink SR, the adjustment of shared resources brought about by the SR will be triggered.

[0175] To ensure the user service experience, within a set time (such as from the receipt of the SR to the successful receipt of the BSR), the available LTE / NR bandwidth will be adjusted according to the similar principle in (1).

[0176] (6) When an uplink service SR request is received in the NR network and the available NR uplink bandwidth is less than the set number of PRBs required for NR uplink SR, the adjustment of shared resources brought about by the SR will be triggered.

[0177] To ensure the user service experience, within a set time (such as from the receipt of the SR to the successful receipt of the BSR), the available LTE / NR bandwidth will be adjusted according to the similar principle in (2).

[0178] (7) When there is a VoLTE service in the LTE network and the current available LTE downlink bandwidth is less than the set number of PRBs required for VoLTE downlink (such as 50% of the full bandwidth) or the available LTE uplink bandwidth is less than the set number of PRBs required for VoLTE uplink (such as 50% of the full bandwidth), to ensure the quality of the voice service, within a set time (such as from the start of the VoLTE service to the end of the VoLTE service), the available LTE / NR bandwidth will be adjusted according to the similar principle in (1).

[0179] (8) When there is a VoNR (Voice over New Radio) service in the NR network and the current available NR downlink bandwidth is less than the set number of PRBs required for VoNR downlink (such as 50% of the full bandwidth) or the available NR uplink bandwidth is less than the set number of PRBs required for VoNR uplink (such as 50% of the full bandwidth), to ensure the quality of the voice service, within a set time (such as from the start of the VoNR service to the end of the VoNR service), the available LTE / NR bandwidth will be adjusted according to the similar principle in (2).

[0180] (9) When multiple causes are triggered simultaneously, it is set that the number of PRBs required for NR needs to take the MAX (the number of PRBs required for NR for all set causes), or the number of PRBs required for LTE needs to take the MAX (the number of PRBs required for LTE for all set causes). This principle applies to both the uplink and the downlink.

[0181] (10) After the set timeouts, the original shared resource allocation will be restored.

[0182] In the embodiments of the present application, after the shared resources are determined, the adjustment and maintenance of the shared resources are carried out, taking into account the impacts of factors such as the arrival of new uplink or downlink services, random access, and handover command sending, ensuring the random access performance and handover performance after sharing, and reducing the decline of user experience and network KPIs.
