Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] Figure 1 Schematic diagram of the implementation process of the bandwidth adjustment method provided in the embodiment of the present application Figure 1 ,like Figure 1 As shown, the embodiment of the present application provides a bandwidth adjustment method, the method comprising the following steps:

[0028] Step 101: Adjust the bandwidth of the cell based on first information; the first information includes at least one of the following: the number of partial bandwidth BWPs in the cell, the number of radio resource control RRC connections of each BWP in the cell, and the carrier utilization of each BWP in the cell.

[0029] In actual application, the BWP can be a RedCap-specific BWP.

[0030] In some optional implementations, adjusting the bandwidth of the cell based on the first information includes:

[0031] Based on the first information, determining whether the cell meets the BWP increase condition; the BWP increase condition includes: all BWPs in the cell meet the expansion condition and the number of BWPs in the cell is less than the maximum configurable BWP number of the cell;

[0032] If the cell meets the BWP adding condition, a new BWP is added in the cell, and the first diversion strategy is adopted to divert users in the cell based on the newly added BWP.

[0033] refer to Figure 2 , Figure 2User allocation diagram provided in the embodiment of the present application Figure 1 , Figure 2 BWP1, BWP2...BWPN-1 are the original BWPs, and BWPN is the newly added BWP. Some users in the original BWP are transferred to the newly added BWPN, so that all BWPs in the cell do not meet the expansion conditions. The user's uplink and downlink services can be assigned to the newly added RedCap dedicated BWP through BWP-DownlinkDedicated and BWP-UplinkDedicated.

[0034] In actual application, considering that eMBB users need to occupy the dedicated BWP including CD-SSB for RRM measurement, RLM measurement, etc., in order to avoid a large number of eMBB and RedCap users gathering in the dedicated BWP including CD-SSB, the RedCap dedicated BWP users including CD-SSB can be preferentially adjusted to other dedicated BWPs including NCD-SSB to ensure the performance of eMBB users.

[0035] New access users will be assigned to the newly added RedCap dedicated BWP on a priority basis to minimize the perception and impact on users who are currently doing business.

[0036] According to the 5QI information or slice ID information obtained by the base station, users with low service assurance priority will be assigned to the newly added RedCap dedicated BWP according to the service assurance priority, so as to minimize the perception and impact on users with high service assurance priority.

[0037] According to the carrier utilization or RRC connection number of other dedicated BWPs, the number of users on the dedicated BWP with the highest carrier utilization or RRC connection number will be assigned to the newly added RedCap dedicated BWP through RRC reconfiguration, and then the number of users on other RedCap dedicated BWPs will be adjusted accordingly. If during the adjustment process, the RedCap dedicated BWP no longer meets the expansion conditions, the RedCap dedicated BWP will no longer adjust and divert users. If during the adjustment process, the newly added RedCap dedicated BWP meets the expansion conditions, users will stop being assigned to the dedicated BWP.

[0038] Considering the coverage of users, such as sorting by uplink RSRP, SINR or downlink PDCCH repetition configuration on the base station side, users whose network signal quality is lower than the first quality threshold are assigned to the newly added RedCap dedicated BWP through RRC reconfiguration to minimize the resource occupancy of the original BWP.

[0039] Based on this, in some optional implementations, the first diversion strategy includes at least one of the following:

[0040] Assigning users on a BWP containing a cell-defining synchronization signal block CD-SSB to a BWP containing a non-cell-defining synchronization signal block NCD-SSB;

[0041] Assign new access users to the newly added BWP;

[0042] Assign users whose service assurance priority is lower than the first priority threshold to the newly added BWP;

[0043] Under the premise of satisfying the second condition, assigning users on the BWP with the highest carrier utilization and / or the highest number of RCC connections to the newly added BWP; the second condition includes at least one of the following: the BWP with the highest carrier utilization and / or the highest number of RCC connections meets the capacity expansion condition and the newly added BWP does not meet the capacity expansion condition; and,

[0044] Users whose network signal quality is lower than a first quality threshold are assigned to the newly added BWP.

[0045] In some optional implementations, the capacity expansion condition includes at least one of the following:

[0046] Within a first preset time, the number of RCC connections of the BWP is greater than or equal to a first expansion threshold; and,

[0047] Within the first preset time, the carrier utilization rate of the BWP is greater than or equal to the second capacity expansion threshold.

[0048] In some optional implementations, adjusting the bandwidth of the cell based on the first information further includes:

[0049] If a part of the BWPs in the cell meet the expansion conditions and another part of the BWPs do not meet the expansion conditions, a second diversion strategy is used to divert users in the cell; the second diversion strategy includes at least one of the following:

[0050] Assign users on the BWP containing CD-SSB to the BWP containing NCD-SSB;

[0051] Assign new access users to BWPs that do not meet the expansion conditions;

[0052] Assign users whose service assurance priority is lower than the first priority threshold to the BWP that does not meet the expansion conditions;

[0053] Under the premise of satisfying the first condition, assigning users on the BWP with the highest carrier utilization and / or the number of RCC connections to the BWP that does not meet the capacity expansion condition; the first condition includes: the BWP with the highest carrier utilization and / or the number of RCC connections meets the capacity expansion condition; and,

[0054] Users whose network signal quality is lower than the first quality threshold are assigned to the BWP that does not meet the expansion condition.

[0055] Execute the second diversion strategy, and adjust some users to the RedCap dedicated BWP that does not meet the expansion requirements through RRC reconfiguration for diversion. If the carrier utilization or RRC connection number of each RedCap dedicated BWP after diversion is within the expansion threshold range, it is determined that the conditions for increasing the RedCap dedicated BWP are not met, then the existing RedCap dedicated BWP configuration is maintained, and there is no need to configure an additional RedCap dedicated BWP.

[0056] In some optional embodiments, the method also includes: if after the second diversion strategy is used to divert users in the cell, there are still BWPs in the cell that meet the expansion conditions and the number of BWPs in the cell is less than the maximum configurable number of BWPs in the cell, then a new BWP is added in the cell, and the first diversion strategy is used to divert users in the cell based on the newly added BWP.

[0057] refer to Figure 3 , Figure 3 User allocation diagram provided in the embodiment of the present application Figure 2 , Figure 2 BWP1, BWP2...BWPN-1 are the original BWPs, among which BWP1 and BWP2 meet the expansion conditions, and BWPN-1 does not meet the expansion conditions. Some users in the BWPs that meet the expansion conditions are assigned to the BWPs that do not meet the expansion conditions, such as assigning some users in BWP1 and BWP2 to BWPN-1, so that each BWP does not meet the expansion conditions.

[0058] refer to Figure 4 , Figure 4 User allocation diagram provided in the embodiment of the present application Figure 3 , Figure 4 Among them, BWP1, BWP2...BWPN-1 are the original BWPs, among which BWP1 and BWP2 meet the capacity expansion conditions, and BWPN-1 does not meet the capacity expansion conditions. Some users in the BWP that meet the capacity expansion conditions are assigned to the BWP that does not meet the capacity expansion conditions, such as assigning some users in BWP1 and BWP2 to BWPN-1, but there are still BWPs that meet the capacity expansion conditions after the assignment. At this time, a new BWP, such as BWPN, is added to bear part of the user pressure; it can be understood that as long as the number of BWPs in the cell does not exceed the maximum configurable number of BWPs in the cell, when there are still BWPs that meet the capacity expansion conditions after the newly added BWP bears the users, a new BWP can be added again to share the user pressure.

[0059] In some optional embodiments, the method also includes: if after the first diversion strategy and / or the second diversion strategy are used to divert users in the cell, there are still BWPs in the cell that meet the expansion conditions and the number of BWPs in the cell is equal to the maximum configurable number of BWPs in the cell, then a new cell and / or a new frequency point is added.

[0060] refer to Figure 5 , Figure 5 User allocation diagram provided in the embodiment of the present application Figure 4 , Figure 5 The number of BWPs in the cell reaches the maximum number of BWPs that can be configured in the cell, and all BWPs meet the expansion conditions. At this time, new cells and / or new frequencies can be added to share the user load.

[0061] In some optional implementations, adjusting the bandwidth of the cell based on the first information further includes:

[0062] Based on the first information, determining whether the cell meets a BWP deletion condition; the BWP deletion condition includes: all BWPs in the cell meet a reduction condition and the number of BWPs in the cell is greater than or equal to a first quantity threshold;

[0063] If the BWP deletion condition is met, the third diversion strategy is adopted to divert the users in the cell, and the BWP without users is deleted.

[0064] In some optional implementations, the deletion condition includes at least one of the following:

[0065] Within a first preset time, the number of RCC connections of the BWP is less than a first deletion threshold; and,

[0066] Within the first preset time, the carrier utilization rate of the BWP is less than the second deletion threshold; wherein,

[0067] The first deletion threshold ≤ (X-1)*the first expansion threshold / X;

[0068] The second deletion threshold ≤ (X-1)*the second expansion threshold / X; wherein X is the number of BWPs in the cell.

[0069] When the number of RCC connections of the BWP is greater than or equal to the first capacity expansion threshold within the first preset time; and / or the carrier utilization rate of the BWP is greater than or equal to the second capacity expansion threshold within the first preset time, the BWP meets the capacity expansion conditions.

[0070] In actual application, the deletion threshold of the number of RRC connections or carrier utilization is customized according to the number of BWPs to ensure that after deleting the RedCap dedicated BWP, the diversion of users to the new dedicated BWP will not cause the remaining RedCap dedicated BWP to exceed the RedCap expansion requirements. The threshold for determining the deletion of the RedCap dedicated BWP is related to the current number of BWPs and the RedCap single BWP expansion threshold, that is, it is necessary to ensure that after the current RedCap dedicated BWP is deleted, the base station will assign users of the current RedCap dedicated BWP to other RedCap dedicated BWPs so that the RedCap single BWP expansion threshold will not be exceeded.

[0071] In some optional implementations, the third diversion strategy includes at least one of the following:

[0072] Assign users on the BWP containing CD-SSB to the BWP containing NCD-SSB;

[0073] Assign users on the BWP containing NCD-SSB to the BWP containing CD-SSB;

[0074] Assign users whose service assurance priority is lower than the first priority threshold from the current BWP to other BWPs;

[0075] Assigning users on the BWP with the lowest carrier utilization and / or number of RCC connections to other BWPs; and,

[0076] Assign users on the BWP with the highest noise floor to other BWPs that do not meet the expansion requirements.

[0077] Taking into account that eMBB users perform RRM measurements, RLM measurements, etc. at the CD-SSB frequency band, in order to avoid a large number of eMBB and RedCap users gathering at the dedicated BWP position including CD-SSB, the RedCap dedicated BWP users including CD-SSB are preferentially adjusted to other dedicated BWPs including NCD-SSB to ensure the performance of eMBB users.

[0078] Considering that the configuration of NCD-SSB for RedCap dedicated BWP will increase system overhead, it is preferred to adjust users of RedCap dedicated BWP configured with NCD-SSB to RedCap dedicated BWP including CD-SSB to minimize the overhead caused by the configuration of NCD-SSB. If there are multiple dedicated BWP configurations for NCD-SSB, and in order to ensure the continuity of the eMBB service frequency band, try to adjust the RedCap dedicated BWP users of NCD-SSB located in the middle of the frequency band to RedCap dedicated BWP including CD-SSB or RedCap dedicated BWP of NCD-SSB at both ends of the frequency band to ensure that eMBB can use the continuous service frequency band to the maximum extent.

[0079] The RedCap dedicated BWPs are sorted according to carrier utilization or number of RRC connections, and the number of users on the dedicated BWP with the lowest carrier utilization or number of RRC connections is preferentially assigned to other RedCap dedicated BWPs that have not met the capacity expansion requirements through RRC reconfiguration, and are preferentially adjusted to the dedicated BWP with the second lowest carrier utilization or number of RRC connections. If the carrier utilization or number of RRC connections of the RedCap dedicated BWP has reached the capacity expansion threshold, the RedCap dedicated BWPs are continued to be sorted according to the latest carrier utilization or number of RRC connections of each RedCap dedicated BWP, and the number of users on the dedicated BWP with the lowest carrier utilization or number of RRC connections is adjusted to the dedicated BWP with the second lowest carrier utilization or number of RRC connections, until there are no users on the original RedCap dedicated BWP with the lowest carrier utilization or number of RRC connections.

[0080] According to the 5QI information or slice ID information obtained by the base station, the service assurance priority of all users is comprehensively considered, and users of RedCap dedicated BWP with low comprehensive service assurance rate are preferentially assigned to other RedCap dedicated BWPs, so as to minimize the perception and impact on users with high service assurance priority, until there are no users on the original RedCap dedicated BWP.

[0081] Sort the RedCap dedicated BWP noise levels from low to high, and prioritize users on the RedCap dedicated BWP with the highest noise level. Reassign them to other RedCap dedicated BWPs that do not meet the capacity expansion requirements through RRC reconfiguration, and prioritize adjusting them to the dedicated BWP with the lowest noise level. If the carrier utilization or RRC connection number of the RedCap dedicated BWP has reached the capacity expansion threshold, adjust them to the RedCap dedicated BWP with the second lowest noise level until there are no users on the original RedCap dedicated BWP with the highest noise level.

[0082] refer to Figure 6 , Figure 6 User allocation diagram provided in the embodiment of the present application Figure 5 In this embodiment, the cell includes two BWPs, namely BWP1 and BWP2. Both BWPs meet the deletion requirements. After BWP2 is deleted and the users on BWP2 are assigned to BWP1, BWP1 does not exceed the expansion threshold.

[0083] In some optional implementations, adjusting the bandwidth of the cell based on the first information further includes:

[0084] If a portion of the BWPs in the cell meet the deletion condition, and another portion of the BWPs do not meet the deletion condition;

[0085] Performing deletion prediction and adjusting the bandwidth of the cell based on the prediction result; wherein the deletion prediction includes:

[0086] Deleting the BWP with the lowest carrier utilization and / or RCC connection number, and using the third offloading strategy to offload users in the cell;

[0087] If all BWPs do not meet the expansion condition after the diversion is completed, the prediction result is to delete the BWP with the lowest carrier utilization rate and / or RCC connection number, and use the third diversion strategy to divert users in the cell;

[0088] If there is a BWP that meets the expansion conditions after the diversion is completed, the prediction result is that the BWP will not be deleted.

[0089] refer to Figure 7 , Figure 7 User allocation diagram provided in the embodiment of the present application Figure 6 In this embodiment, the cell includes two BWPs, namely BWP1 and BWP2. Both BWPs do not meet the deletion requirements and are not processed.

[0090] In actual application, if only a single dedicated BWP is currently configured for RedCap, that is, only a single dedicated BWP is available for RedCap users, the RedCap dedicated deletion condition determination will not be performed.

[0091] It should be noted that the various diversion means in the first diversion strategy, the second diversion strategy or the third diversion strategy in the embodiments of the present application can be used alone or in combination according to actual conditions, and the present application does not limit this.

[0092] Furthermore, it should be noted that the bandwidth adjustment method provided in the embodiment of the present application can be implemented by a device such as a base station, a network management platform or a server alone, or by a combination of multiple device nodes, and the present application does not limit this. Figure 8 , Figure 8 The implementation process of the bandwidth adjustment method provided in the embodiment of the present application is as follows Figure 2 ,like Figure 8 As shown, the method includes:

[0093] Step 801: The network management platform reports the existing / updated BWP related information to the server.

[0094] Step 802: The server evaluates whether the BWP addition and deletion conditions are met based on the information reported by the network management platform.

[0095] Step 803: The server makes user diversion suggestions and / or adds or deletes instructions and sends them to the network management platform.

[0096] Step 804: The network management platform configures the user diversion suggestion and / or the addition and deletion instruction to the base station.

[0097] Step 805: The base station balances the users of each BWP through dedicated signaling based on the user diversion suggestion and / or the addition and deletion instruction.

[0098] Step 806: The base station uploads updated information such as utilization rate of each carrier and number of users to the network management platform.
