[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Combine the following Figure 1-Figure 4 The invention describes a method, a device and an electronic device for allocating virtual resource blocks.

[0022] Figure 1 It is one of the flow charts of the method for allocating virtual resource blocks provided by the present invention, such as Figure 1 As shown, the method for allocating virtual resource blocks includes S100 to S500, and each step is specifically as follows.

[0023] S100: Obtain a range of common resource blocks CRBs that can be allocated corresponding to the current user terminal to be allocated, obtain a used virtual resource block VRB index value based on the used CRBs within the range of CRBs, and then obtain an unused VRB index value within the range of CRBs; the range of CRBs is determined based on the configuration information of the current bandwidth part of the current user terminal.

[0024] Before the downlink medium access control layer (MAC) of the base station allocates frequency domain resources to the current user terminal (UE) to be allocated, it first determines the range of CRBs that can be allocated to the current user terminal according to the current bandwidth part (Bandwidth Part, BWP) configuration information of the current user terminal.

[0025] Obtain the used CRB within the range of the CRB, and convert the used CRB into the used PRB corresponding to the current BWP configuration information. Further, according to the interleaving mapping information of VRB to PRB, obtain the used VRB index value corresponding to the used PRB. According to the current BWP configuration information, the entire VRB range can be obtained. Remove the used VRB index value from the entire VRB range to obtain the unused VRB index value.

[0026] S200: Allocate a VRB for the current user terminal from unused VRB index values ​​according to a preset resource allocation protocol, and obtain an allocated VRB index value of the current user terminal.

[0027] According to the preset resource allocation protocol between the current user terminal and the base station, VRB index values ​​that meet the quantity requirement are allocated to the current user terminal from unused VRB index values, and these VRB index values ​​are marked as "allocated" to obtain the allocated VRB index values ​​of the current user terminal.

[0028] S300: Determine an allocated PRB index value based on an allocated VRB index value, and obtain an allocated CRB based on the allocated PRB index value.

[0029] According to the interleaving mapping information of VRB to PRB, the allocated VRB index value is converted into the allocated PRB index value. According to the current BWP configuration information corresponding to the user terminal, the allocated PRB index value is converted into a CRB index value with global characteristics, and these CRB index values ​​are marked as "allocated" to obtain the allocated CRB of the user terminal.

[0030] S400: updating the used CRB based on the allocated CRB to update the used VRB index value, and obtaining the updated unused VRB index value based on the updated used VRB index value.

[0031] Before allocating VRBs for the next user terminal (any one of the remaining user terminals), the allocated CRBs are added to the used CRBs to obtain updated used CRBs. Based on the above steps, an updated used VRB index value is determined according to the updated used CRBs. Within the range of all VRBs, an updated unused VRB index value is obtained according to the updated used VRB index value.

[0032] S500: Allocate a VRB for the next user terminal in the updated unused VRB index value until all initial CRBs within the range of the CRB are used, or until all user terminals are allocated VRBs.

[0033] According to the preset resource allocation protocol between the next user terminal and the base station, VRBs are allocated to the next user terminal in the updated unused VRB index values. The used VRBs are updated cyclically, and then the used CRBs are updated until all initial CRBs are marked as "allocated" (all used) within the range of CRBs that can be allocated, or until all user terminals are allocated VRBs. At this point, the allocation of virtual resource blocks VRBs is terminated.

[0034] The virtual resource block allocation method provided by the present invention marks the allocated VRB index value and the allocated PRB index value according to the allocated CRB, so as to ensure that the VRBs allocated to different user terminals do not conflict with each other in the frequency domain after being interleaved into PRBs. The present invention obtains the unused VRB index value according to the used CRB, which is conducive to timely updating the unused VRB and improving the accuracy of VRB allocation to the user terminal.

[0035] Based on the above embodiment, based on the used CRBs within the CRB range, the used virtual resource block VRB index value is obtained, and then the unused VRB index value within the CRB range is obtained, including S110 to S130, and each step is specifically as follows.

[0036] S110: Based on the used CRB, obtain the used physical resource blocks PRB.

[0037] S120: Based on the interleaving mapping information from VRB to PRB, deinterleave mapping is performed on the used PRB to obtain the used VRB index value.

[0038] S130: Acquire all VRB ranges corresponding to the CRB range, and acquire unused VRB index values ​​based on all VRB ranges and used VRB index values.

[0039] According to the BWP configuration information of the current user terminal, the used CRB is converted into the used PRB. Further, the used PRB (PrbIdx) is converted into the PRB bundle index value (PrbBundleIdx) and the resource block index value of the PRB bundle.

[0040] (1) If the current user terminal belongs to a system information block (SIB), the physical downlink control channel (PDCCH) of the current user terminal is scrambled by the system information radio network temporary identifier (SI-RNTI), and the PDCCH is carried in the cell-specific search space of the first setting type (type0) associated with the setting control resource set (Coreset 0), then the number of unit resource blocks (RBs) contained in a resource bundle (PRB bundle or VRB bundle) is fixed to L, for example, L=2. The calculation formula for the number of resource bundles (PRB bundle or VRB bundle) is: N_bundle=ceil(1.0×CoresetZero_Size / L), where N_bundle is the number of resource bundles and CoresetZero_Size is the number of common resource blocks occupied by Coreset 0.

[0041] The calculation formula of the used PRB (PrbIdx) corresponding to the used CRB (CrbIdx) is: used PrbIdx = used CrbIdx - CoresetZero_Start. CoresetZero_Start is the index value of the first starting common resource block of Coreset 0.

[0042] The calculation formula of the PRB bundle index value to which the used PRB belongs is: PrbBundleIdx=usedPrbIdx / L.

[0043] The resource block index value (RbIdxWithinBundle) of the PRB bundle is calculated as follows: RbIdxWithinBundle of the PRB bundle = used PrbIdx mod L. Wherein, mod is the remainder of the quotient of used PrbIdx and L.

[0044] (2)If the scheduling of DCI format 1-0 in the cell-specific search space other than type 0 is used by the user terminal. First, it is necessary to determine whether the cell search space other than type 0 belongs to the set control resource set (Coreset0). If the search space of the user terminal belongs to Coreset0, the calculation formula for the index value of the second starting common resource block (CommonCoresetStart) is: CommonCoresetStart = CoresetZero_Start - DlBwpStart; DlBwpStart is the index value of the starting common resource block of the downlink bandwidth part used by the current user terminal.

[0045] If the search space of the user terminal does not belong to Coreset0 (belongs to the common control resource set), CommonCoresetStart = 6 × ceil(1.0 × DlBwpStart / 6) + (1stBit1PosInCommonCoresetFreqDomainCfg - 1) × 6 - DlBwpStart; where 1stBit1PosInCommonCoresetFreqDomainCfg is the position of the first (starting from the left high bit) bit 1 of the common control resource set used by the PDCCH of the current user terminal (determined by the configuration parameters of the common control resource set of the base station).

[0046] The calculation formula for the number of resource bundles is: N_bundle = ceil(1.0 × (CoresetZero_Size + (DlBwpStart + CommonCoresetStart) mod L) / L).

[0047] The calculation formula for the number of resource blocks included in the first resource bundle (RbNumInFirstBundle) is: RbNumInFirstBundle = L - (DlBwpStart + CommonCoresetStart) mod L.

[0048] The calculation formula for the used PRB is: Used PrbIdx = Used CrbIdx - DlBwpStart - CommonCoresetStart.

[0049] If Used PrbIdx < RbNumInFirstBundle, then: PrbBundleIdx = 0, and RbIdxWithinBundle of the PRB bundle = Used PrbIdx.

[0050] If the used PrbIdx > RbNumInFirstBundle + (N_bundle - 2) × L - 1, then: PrbBundleIdx = N_bundle - 1, and RbIdxWithinBundle of the PRB bundle = used PrbIdx - (RbNumInFirstBundle + (N_bundle - 2) × L).

[0051] Except for the above two cases, PrbBundleIdx = ceil(1.0 × (used PrbIdx + 1 - RbNumInFirstBundle) / L), and RbIdxWithinBundle of the PRB bundle = (used PrbIdx - RbNumInFirstBundle) mod L.

[0052] (3)If the current user equipment belongs to the scheduling of other Physical Downlink Shared Channels (PDSCH), the number of resource blocks L included in a resource bundle is determined by the cell configuration. N_bundle = ceil(1.0 × (DlBwpSize + DlBwpStart mod L) / L). RbNumInFirstBundle = L - DlBwpStart mod L.

[0053] Used PrbIdx = used CrbIdx - DlBwpStart.

[0054] If the used PrbIdx < RbNumInFirstBundle, then PrbBundleIdx = 0, and RbIdxWithinBundle of the PRB bundle = used PrbIdx.

[0055] If the used PrbIdx > RbNumInFirstBundle + (N_bundle - 2) × L - 1, then PrbBundleIdx = N_bundle - 1, and RbIdxWithinBundle of the PRB bundle = used PrbIdx - (RbNumInFirstBundle + (N_bundle - 2) × L); Except for the above two cases, PrbBundleIdx = ceil(1.0 × (used PrbIdx + 1 - RbNumInFirstBundle) / L), and RbIdxWithinBundle of the PRB bundle = (used PrbIdx - RbNumInFirstBundle) mod L.

[0056] According to the interleaving mapping information from VRB to PRB, the PRB bundle index value and the resource block index value of the PRB bundle obtained above are deinterleaved and mapped to obtain the used VRB index value. The entire VRB range is further obtained, and the unused VRB index value is obtained according to the entire VRB range and the used VRB index value.

[0057] The present invention obtains the used VRB index value according to the used CRB, and then obtains the unused VRB index value, which is beneficial to improving the accuracy of allocating VRBs to user terminals.

[0058] Based on the above embodiment, the interleaving mapping information includes the number of resource bundles corresponding to the range of CRB, the number of unit resource blocks contained in a resource bundle and the number of rows of the interleaver of PRB and VRB, the used PRB includes the PRB bundle index value and the resource block index value of the PRB bundle, based on the VRB to PRB interleaving mapping information, the used PRB is deinterleaved and mapped, and the used VRB index value is obtained, including S121 to S123, and each step is specifically as follows.

[0059] S121: When the PRB bundle index value is not the last resource bundle index value corresponding to the number of resource bundles, determine the VRB bundle index value based on the number of resource bundles, the number of interleaver rows and the PRB bundle index value; when the PRB bundle index value is the last resource bundle index value, use the last resource bundle index value as the VRB bundle index value.

[0060] S122: When the VRB bundle index value corresponds to the first VRB bundle index, determine the used VRB index value based on the resource block index value of the PRB bundle.

[0061] S123: When the VRB bundle index value does not correspond to the first VRB bundle index value, determine the used VRB index value based on the VRB bundle index value, the number of unit resource blocks, the number of resource blocks included in the first resource bundle, and the resource block index value of the PRB bundle.

[0062] The used PRB includes a PRB bundle index value (PrbBundleIdx) and a resource block index value of the PRB bundle (RbIdxWithinBundle).

[0063] Assume that the current user terminal belongs to a system information block (System Information Block, SIB), the physical downlink control channel (Physical Downlink Control Channel, PDCCH) of the current user terminal is scrambled by the system information radio network temporary identifier (System Information Radio Network Temporary Identifier, SI-RNTI), and the PDCCH is carried in the cell-specific search space of the first setting type (type0) associated with the set control resource set (Coreset 0).

[0064] If the PRB bundle index value is the last resource bundle index value (N_bundle-1) among all resource bundles, the VRB bundle index value (VrbBundleIdx) is equal to N_bundle-1.

[0065] If the PRB bundle index value is not the last resource bundle index value (N_bundle-1) among all resource bundles, the VRB bundle index value is calculated according to the number of resource bundles, the number of interleaver rows, and the PRB bundle index value.

[0066] After the VRB bundle index value is calculated, it is determined whether the VRB bundle index value is the first VRB bundle index value (0).

[0067] If the VRB bundle index value is equal to the first VRB bundle index value (the VRB bundle index value corresponds to the first VRB bundle), that is, VrbBundleIdx=0, then the used VRB index value (VrbIdx) is determined directly according to the resource block index value (RbIdxWithinBundle) of the PRB bundle. That is, the used VrbIdx=RbIdxWithinBundle of the PRB bundle.

[0068] If the VRB bundle index value is not equal to the first VRB bundle index value (the VRB bundle index value does not correspond to the first VRB bundle), that is, VrbBundleIdx≠0, the used VRB index value is determined according to the VRB bundle index value (VrbBundleIdx), the number of unit resource blocks (L), the number of resource blocks contained in the first resource bundle (RbNumInFirstBundle) and the resource block index value of the PRB bundle (RbIdxWithinBundle). That is, the used VrbIdx=RbNumInFirstBundle+(VrbBundleIdx-1)×L+PRB bundle RbIdxWithinBundle.

[0069] The present invention determines VRB bundle index values ​​according to PRB index values, thereby improving the accuracy of determining VRB bundle index values. Further, according to VRB bundle index values, used VRB index values ​​are determined according to different situations, thereby achieving accurate deinterleaving from PRB index values ​​to VRB index values.

[0070] Based on the above embodiment, the VRB bundle index value is determined based on the number of resource bundles, the number of interleaver rows and the PRB bundle index value, including S1211 to S1214, and each step is specifically as follows.

[0071] S1211: Determine the number of columns of the interleaver based on the number of resource bundles and the number of rows of the interleaver.

[0072] S1212: Determine a row index value of a VRB based on an integer of a ratio of a PRB bundle index value to the number of columns of an interleaver.

[0073] S1213: Determine a column index value of a VRB based on a remainder of a ratio of a PRB bundle index value to the number of columns of an interleaver.

[0074] S1214: Determine a VRB bundle index value based on the number of rows of the interleaver, the row index value of the VRB, and the column index value of the VRB.

[0075] The calculation formula for the number of columns of the interleaver is: C=N_bundle / R; where C is the number of columns of the interleaver, N_bundle is the number of resource bundles, and R is the number of rows of the interleaver.

[0076] VRB row index value (VRB r ) is calculated as follows: VRB r =PrbBundleIdx / C; where PrbBundleIdx is the PRB bundle index value and C is the number of columns of the interleaver.

[0077] VRB column index value (VRB c ) is calculated as follows: VRB c =PrbBundleIdx mod C; where mod is the remainder of the quotient of PrbBundleIdx and C.

[0078] The calculation formula of VRB bundle index value (VrbBundleIdx) is: VrbBundleIdx=VRB c ×R+VRB r .

[0079] The present invention realizes accurate calculation of VRB bundle index values ​​through VRB row index values, VRB column index values ​​and the number of rows of an interleaver, thereby improving the accuracy of calculating VRB bundle index values.

[0080] Based on the above embodiment, determining the allocated PRB index value based on the allocated VRB index value includes S310 to S340, and each step is specifically as follows.

[0081] S310: Based on the allocated VRB index value, obtain a VRB bundle index value and a resource block index value of the VRB bundle.

[0082] S320: When the VRB bundle index value is not the last resource bundle index value, determine the PRB bundle index value based on the number of resource bundles, the number of interleaver rows and the VRB bundle index value; when the VRB bundle index value is the last resource bundle index value, use the last resource bundle index value as the PRB bundle index value.

[0083] S330: When the PRB bundle index value corresponds to the first PRB bundle, determine the allocated PRB index value based on the resource block index value of the VRB bundle.

[0084] S340: When the PRB bundle index value does not correspond to the first PRB bundle, determine the allocated PRB index value based on the PRB bundle index value, the number of unit resource blocks, the number of resource blocks included in the first resource bundle, and the resource block index value of the VRB bundle.

[0085] According to the allocated VRB index value (VrbIdx), the VRB bundle index value (VrbBundleIdx) and the resource block index value (RbIdxWithinBundle) of the VRB bundle are calculated. VrbBundleIdx = allocated VrbIdx / L. RbIdxWithinBundle of the VRB bundle = allocated VrbIdx mod L; where mod is the remainder of the quotient of the allocated VrbIdx and L.

[0086] If the VRB bundle index value (VrbBundleIdx) is the last resource bundle index value (N_bundle-1), the PRB bundle index value is equal to the last resource bundle index value (N_bundle-1).

[0087] If the VRB bundle index value is not the last resource bundle index value, the PRB bundle index value is determined according to the number of resource bundles (N_bundle), R and the VRB bundle index value.

[0088] Calculate the number of columns C of the interleaver: C = N_bundle / R; where R is the number of rows of the interleaver.

[0089] The row index value of PRB r ) is calculated as: r=VrbBundleIdx / C; where PrbBundleIdx is the PRB bundle index value and C is the number of columns of the interleaver.

[0090] The column index value of PRB (PRB c ) is calculated as: c = VrbBundleIdx mod C; where mod is the remainder of the quotient of PrbBundleIdx and C.

[0091] The calculation formula for the PRB bundle index value (PrbBundleIdx) is: PrbBundleIdx=PRB c ×R+PRB r .

[0092] If the PRB bundle index value is equal to the first PRB bundle index value (the PRB bundle index value corresponds to the first PRB bundle), that is, PrbBundleIdx=0, then the allocated PRB index value (PrbIdx) is determined directly according to the resource block index value (RbIdxWithinBundle) of the VRB bundle. The allocated PrbIdx=RbIdxWithinBundle of the VRB bundle.

[0093] If the PRB bundle index value is not equal to the first PRB bundle index value (the PRB bundle index value does not correspond to the first PRB bundle), the allocated PRB index value is determined according to the PRB bundle index value, L, the number of resource blocks contained in the first resource bundle (RbNumInFirstBundle), and the resource block index value of the VRB bundle. Allocated PrbIdx = RbNumInFirstBundle + (PrbBundleIdx-1)L + RbIdxWithinBundle of the VRB bundle.

[0094] The present invention determines the PRB bundle index value according to the VRB index value, thereby improving the accuracy of determining the PRB bundle index value. Further, according to the PRB bundle index value, the allocated PRB index value is determined according to the PRB bundle index value, thereby improving the accuracy of determining the PRB index value according to the VRB index value.

[0095] Based on the above embodiment, the allocated CRB is obtained based on the allocated PRB index value, including S350 to S380, and each step is specifically as follows.

[0096] S350: Acquire a current search space of a physical downlink control channel corresponding to a current user terminal.

[0097] S360: If the current search space belongs to the first setting type, the allocated CRB is obtained based on the index value of the first starting common resource block of the setting control resource set corresponding to the search space of the first setting type and the allocated PRB index value.

[0098] S370: If the current search space belongs to the second setting type, then based on the index value of the second starting common resource block of the common control resource set corresponding to the search space of the second setting type, the allocated PRB index value is updated, and based on the updated allocated PRB index value and the index value of the starting common resource block of the downlink bandwidth part used by the current user terminal, the allocated CRB is obtained.

[0099] S380: If the current search space belongs to neither the first setting type nor the second setting type, the allocated CRB is obtained based on the allocated PRB index value and the index value of the starting common resource block of the downlink bandwidth part.

[0100] The first setting type is a cell-specific search space of type 0 associated with a setting control resource set (Coreset 0). The second setting type is a cell-specific search space of non-type 0 associated with a common control resource set (CommonCoreset).

[0101] Get the current search space of the physical downlink control channel (PDCCH) corresponding to the current user terminal.

[0102] If the current search space belongs to the first setting type, the allocated CRB (CrbIdx) is determined according to the index value of the first starting common resource block (CoresetZero_Start) and the allocated PRB index value (PrbIdx). Allocated CrbIdx=allocated PrbIdx+CoresetZero_Start.

[0103] If the current search space belongs to the second setting type, the allocated PRB index value is updated according to the index value of the second starting common resource block (CommonCoresetStart). Updated allocated PrbIdx = allocated PrbIdx + CommonCoresetStart. According to the updated allocated PRB index value and the index value of the starting common resource block of the downlink bandwidth part used by the current user terminal (DlBwpStart), the allocated CRB is calculated. Allocated CrbIdx = updated allocated PrbIdx + DlBwpStart.

[0104] If the current search space belongs to neither the first setting type nor the second setting type, the allocated CRB is calculated according to the allocated PRB index value and the index value of the starting common resource block of the downlink bandwidth part. Allocated CrbIdx=Allocated PrbIdx+DlBwpStart.

[0105] The present invention determines the allocated CRB according to different types of the current search space, thereby improving the accuracy of determining the allocated CRB.

[0106] Based on the above embodiment, the range of CRB includes the CRB index upper limit and the CRB index lower limit, and the range of the common resource block CRB that can be allocated corresponding to the current user terminal to be allocated is obtained, including S140 to S150, and each step is specifically as follows.

[0107] S140: When the search space belongs to a set control resource set, the index value of the first starting public resource block corresponding to the set control resource set is used as the CRB index lower limit, and the CRB index upper limit is determined based on the index value of the first starting public resource block and the number of CRBs in the set control resource set.

[0108] S150: When the search space belongs to a common control resource set, the lower limit of the CRB index is determined based on the index value of the starting common resource block of the downlink bandwidth part and the position of the first bit 1 of the common control resource set, and the upper limit of the CRB index is determined based on the index value of the starting common resource block of the downlink bandwidth part, the position of the first bit 1 of the common control resource set and the number of CRBs in the set control resource set.

[0109] S160: When the search space belongs neither to the set control resource set nor to the public control resource set, the lower limit of the CRB index is determined based on the index value of the starting public resource block of the downlink bandwidth part, and the upper limit of the CRB index is determined based on the index value of the starting public resource block of the downlink bandwidth part and the number of CRBs in the public control resource set.

[0110] (1) If the current user terminal belongs to the SIB, its PDCCH is scrambled by SI-RNTI, and the PDCCH is carried in the search space of the first setting type (type0) related to the setting control resource set (Coreset 0). Then the range of CRBs that can be used for this physical downlink shared channel (PDSCH) transmission is the CRB range where Coreset 0 is located. The range of CRBs includes the CRB index upper limit (AvailableCrbUpperLimit) and the CRB index lower limit (AvailableCrbLowerLimit).

[0111] AvailableCrbLowerLimit=CoresetZero_Start, where CoresetZero_Start is the index value of the first starting common resource block.

[0112] AvailableCrbUpperLimit = CoresetZero_Start + CoresetZero_Size - 1, where CoresetZero_Size is the number of CRBs in the control resource set.

[0113] (2) If the PDCCH corresponding to the current user terminal is carried in the cell search space of the second setting type (non-type0) related to Coreset 0, the range of CRBs that can be allocated to the current user terminal is still calculated according to the CRB range of Coreset 0.

[0114] If the PDCCH corresponding to the current user terminal is carried in the cell search space of the second setting type (non-type0) of the common control resource set (common coreset), then the range of CRBs that can be used for this PDSCH transmission is the CRB range where the common control resource set is located.

[0115] AvailableCrbLowerLimit=6×ceil(1.0×DlBwpStart / 6)+(1stBit1PosInCommonCoresetFreqDomainCfg-1)×6.

[0116] AvailableCrbUpperLimit=6×ceil(1.0×DlBwpStart / 6)+(1stBit1PosInCommonCoresetFreqDomainCfg-1)×6+CoresetZero_Size-1.

[0117] Among them, AvailableCrbLowerLimit is the lower limit of the CRB index, ceil() is the minimum integer, DlBwpStart is the index value of the starting common resource block of the downlink bandwidth part used by the current user terminal, and 1stBit1PosInCommonCoresetFreqDomainCfg is the position of the first bit 1 of the common control resource set used by the PDCCH of the current user terminal.

[0118] (3) When the downlink medium access control layer (MAC) scheduler of the base station schedules PDSCH transmissions other than the above cases (the search space belongs neither to the set control resource set nor to the common control resource set), the CRB range that can be allocated is the CRB within the BWP range used by the current user terminal.

[0119] AvailableCrbLowerLimit=DlBwpStart.

[0120] AvailableCrbUpperLimit=DlBwpStart+DlBwpSize-1.

[0121] Among them, DlBwpSize is the number of CRBs in the common control resource set occupied by the downlink bandwidth used by the current user terminal.

[0122] The present invention determines the range of CRBs that can be allocated according to different search space types, thereby improving the accuracy of determining the range of CRBs.
