Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular, to a method and system for allocating BWP frequency domain resources. Background Art

[0002] In a 5G NR (5th Generation Mobile Communication Technology New Radio) system, currently when a base station has overlapping frequency domain resources of multiple BWPs (Bandwidth Parts), when it is necessary to allocate frequency domain resources within one of the BWPs, the factor of overlapping with the frequency domain range of this BWP is not considered. According to the current established rules, for example, resources are allocated sequentially from low frequency to high frequency, or allocated sequentially in the reverse order.

[0003] When the base station adopts the above allocation method, if there are overlapping frequency domain resources of multiple BWPs, when allocating the frequency domain resources of the current BWP, it may first occupy the resources in the overlapping part of the frequency domain of this BWP. When the finally allocated frequency domain resources of this BWP do not fully occupy the entire bandwidth of this BWP, and the resources required by other BWPs overlapping with the frequency domain of this BWP are large, other BWPs cannot allocate the overlapping frequency domain resources, and the unoccupied BWP frequency domain resources of this BWP are wasted, which will lead to waste of cell spectrum resources, as well as problems such as low service throughput and large delay within some BWPs.

[0004] Therefore, it is necessary to propose a new method for allocating BWP frequency domain resources, which can reasonably allocate BWP frequency domain resources. Summary of the Invention

[0005] The present invention provides a method and system for allocating BWP frequency domain resources to solve the defect that in the prior art, when a base station allocates frequency domain resources of multiple overlapping BWPs in a 5G NR system, the resources in the overlapping part of the frequency domain cannot be effectively utilized, resulting in serious waste of frequency domain resources.

[0014] Otherwise, if it is judged that the first starting point is less than the second starting point, and the first cut-off point is greater than the second starting point, and the first cut-off point is less than the second cut-off point, then allocate frequency domain resources starting from the first starting point of the currently scheduled BWP frequency domain.

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0039] Figure 1It is a schematic flowchart of the BWP frequency domain resource allocation method provided by the present invention. As Figure 1 shown, it includes:

[0040] Step S1: Obtain multiple partial bandwidth BWP frequency domains, determine the currently scheduled BWP frequency domain among the multiple partial bandwidth BWP frequency domains, and several BWP frequency domains whose frequency bandwidth ranges overlap with the currently scheduled BWP frequency domain;

[0041] Step S2: Based on the overlap type between the currently scheduled BWP frequency domain and the several BWP frequency domains, determine the frequency domain resource allocation for the currently scheduled BWP frequency domain.

[0042] Specifically, in the 5G NR system, when multiple BWPs are configured, the base station judges according to the positions of the currently scheduled BWP frequency domain and other unscheduled BWP frequency domains, and determines the frequency domain resource allocation method of the currently scheduled BWP according to whether the two BWPs overlap and the type of overlap.

[0043] In the present invention, when multiple BWP frequency domain resources overlap, there are four types of overlaps, as Figures 2 to 5 shown, Figure 2 is the high frequency of the BWP overlapping with the low frequency of other BWPs in the frequency domain; Figure 3 is the low frequency of the BWP overlapping with the high frequency of other BWPs in the frequency domain; Figure 4 is that the frequency domain of the high BWP is completely included in the frequency domain of other BWPs; Figure 5 is that the frequency domain of the BWP completely includes the frequency domain of other BWPs.

[0044] When determining the BWP frequency domain priority, set the currently scheduled BWP-ID = M1, the next unscheduled BWP-ID = M2, and M1 < M2. M1 and M2 are integers whose BWP-ID value ranges are (0, 1,..., maxNrofBWPs) according to the provisions of 3GPP 38.331, where maxNrofBWPs = 4.

[0045] In the present invention, when there are multiple overlapping BWP frequency domain resources, through a reasonable frequency domain resource allocation method, it can not only meet the service requirements within each BWP, but also improve the overall spectrum utilization rate of the cell, increase the cell throughput, and reduce the service delay.

[0046] Based on the above embodiments, step S1 includes:

[0047] Determine the frequency domain start position of the currently scheduled BWP frequency domain as the first starting point, and the frequency domain end position of the currently scheduled BWP frequency domain as the first cut-off point;

[0048] According to the BWP-ID priority identifier, obtain any BWP frequency domain with a priority adjacent to that of the current scheduled BWP among the several BWP frequency domains, and determine the start position of the frequency domain of the any BWP frequency domain as the second starting point and the end position of the frequency domain of the any BWP frequency domain as the second cut-off point.

[0049] Specifically, for the convenience of comparison, in the present invention, the start and end of the RB (Resource Block) with BWP-ID = M1 are N1_start (the first starting point) and N1_end (the first cut-off point) respectively; the start and end of the RB with BWP-ID = M2 are N2_start (the second starting point) and N2_end (the second cut-off point) respectively; here, N1_start, N1_end, N2_start, and N2_end are all within the frequency domain bandwidth configured for the current cell. For example, if the frequency domain bandwidth configured for the cell is 100 MHz and the subcarrier spacing is 30 kHz, then according to the provisions of 3GPP 38.101, the total number of RBs occupied by the cell frequency domain N_max = 273, and the value ranges of N1_start, N1_end, N2_start, and N2_end are integers in (0, 1,..., 272).

[0050] The present invention facilitates the comparison of the overlapping parts of the frequency domain and outputs the corresponding frequency domain allocation method by setting the start points and end points of the current BWP frequency domain and other unscheduled BWP frequency domains.

[0051] Based on any of the above embodiments, step S2 includes:

[0052] If it is judged that the priority identifier of the any BWP frequency domain is greater than the value range of the BWP-ID priority identifier, then allocate frequency domain resources starting from the first starting point or the first cut-off point of the current scheduled BWP frequency domain;

[0053] Otherwise, if it is judged that the first starting point is less than the second starting point, and the first cut-off point is greater than the second starting point, and the first cut-off point is less than the second cut-off point, then allocate frequency domain resources starting from the first starting point of the current scheduled BWP frequency domain.

[0054] Optionally, if the currently scheduled BWP-ID = M1, then the next BWP-ID = M2. If M2 > maxNrofBWPs, that is, M2 exceeds the value range of the BWP-ID priority identifier, then the current BWP-ID = M1 allocates frequency domain resources starting from N1_start or N1_end, and then ends the process; when the next unscheduled BWP-ID = M2 > maxNrofBWPs here, it means there is no next BWP-ID, that is, all BWPs have been judged and completed, then the currently scheduled BWP-ID = M1 can allocate frequency domain resources starting from N1_start or N1_end.

[0055] Otherwise, if the high frequency of BWP-ID = M1 overlaps with the low frequency of BWP-ID = M2 in the frequency domain, as Figure 2 shown, that is, N1_start < N2_start and N1_end > N2_start and N1_end < N2_end, then the current BWP-ID = M1 allocates frequency domain resources starting from N1_start, and then ends the process.

[0056] The present invention judges that other unscheduled BWP resources are not within the priority range, and there is an overlap between the high frequency of the currently scheduled BWP and the low frequency of other unscheduled BWPs, and outputs the corresponding frequency domain resource allocation scheme.

[0057] Based on any of the above embodiments, step S2 further includes:

[0058] If it is judged that the first starting point is greater than the second starting point, and the first starting point is less than the second cut-off point, and the first cut-off point is greater than the second cut-off point, then allocate frequency domain resources starting from the first cut-off point of the currently scheduled BWP frequency domain;

[0059] Otherwise, if it is judged that the first starting point is greater than the second starting point, and the first starting point is less than the second cut-off point, and the first cut-off point is greater than the second starting point, and the first cut-off point is less than the second cut-off point, then allocate frequency domain resources starting from the first starting point or the first cut-off point of the currently scheduled BWP frequency domain.

[0060] Optionally, if the low frequency of BWP-ID = M1 overlaps with the high frequency of BWP-ID = M2 in the frequency domain, as Figure 3 shown, that is, N1_start > N2_start and N1_start < N2_end and N1_end > N2_end, then the current BWP-ID = M1 allocates frequency domain resources starting from N1_end, and then ends the process.

[0061] Otherwise, when the frequency domain of BWP-ID = M1 is completely included in the frequency domain of BWP-ID = M2, as Figure 4 shown, that is, N1_start > N2_start and N1_start < N2_end and N1_end > N2_start and N1_end < N2_end, then the currently scheduled BWP-ID = M1 can allocate frequency domain resources starting from N1_start or N1_end, and then end the process.

[0062] The present invention determines whether there is an overlap between the low frequency of the currently scheduled BWP and the high frequency of other unscheduled BWPs, and whether the frequency domain of the high BWP is completely included in the frequency domain of other BWPs, and outputs the corresponding frequency domain resource allocation scheme.

[0063] Based on any of the above embodiments, step S2 further includes:

[0064] If it is determined that the first start point is less than the second start point, and the first start point is less than the second cut-off point, and the first cut-off point is greater than the second start point, and the first cut-off point is greater than the second cut-off point, then allocate frequency domain resources starting from the first start point or the first cut-off point of the currently scheduled BWP frequency domain;

[0065] Otherwise, if the frequency domain of the currently scheduled BWP does not overlap with the frequency domain of any BWP, continue to judge the BWP frequency domain corresponding to the next BWP-ID.

[0066] Optionally, if the frequency domain of BWP-ID = M1 completely includes the frequency domain of BWP-ID = M2, as Figure 5 shown, that is, N1_start < N2_start and N1_start < N2_end and N1_end > N2_start and N1_end > N2_end, then the currently scheduled BWP-ID = M1 can allocate frequency domain resources starting from N1_start or N1_end.

[0067] It should be noted that if N1_start, N1_end, N2_start, and N2_end of BWP-ID = M1 and BWP-ID = M2 do not meet all the above conditions, then the frequency domains of BWP-ID = M1 and BWP-ID = M2 do not overlap, and continue to judge the next BWP-ID, that is, M2 = M2 + 1;

[0068] Starting from the current scheduling BWP-ID, in ascending order of BWP-ID, determine the frequency domain positions of the current BWP and other BWPs. If there is any other BWP that overlaps with the current BWP in the frequency domain, according to the aforementioned four overlapping cases, start resource allocation for the current BWP until the resource allocation is completed, and no longer judge subsequent other BWPs.

[0069] The present invention judges the situation where the frequency domain of the current BWP completely contains the frequency domain of other BWPs, and also judges the situation where the frequency domains do not overlap at all, and outputs corresponding frequency domain resource allocation schemes respectively.

[0070] The following uses Figure 6 the embodiment of the BWP frequency domain resource allocation flowchart shown for illustration. The specific steps include:

[0071] Step 1: When the frequency domain resources of multiple BWPs overlap, the types of frequency domain overlap are defined as four, such as Figures 2 to 5 , Figure 2 the high frequency of the BWP overlaps with the low frequency of other BWPs in the frequency domain; Figure 3 the low frequency of the BWP overlaps with the high frequency of other BWPs in the frequency domain; Figure 4 the frequency domain of the high BWP is completely included in the frequency domain of other BWPs; Figure 5 the frequency domain of the BWP completely contains the frequency domain of other BWPs;

[0072] Step 2: The BWP-ID of the current scheduling is M1, the BWP-ID of the next unscheduled one is M2, and M1 < M2. M1 and M2 are integers within the range of BWP-ID values specified by 3GPP 38.331 as (0, 1,..., maxNrofBWPs), where maxNrofBWPs = 4;

[0073] Step 3: Set the start and end of the RBs with BWP-ID = M1 to N1_start and N1_end respectively; set the start and end of the RBs with BWP-ID = M2 to N2_start and N2_end respectively; N1_start, N1_end, N2_start, and N2_end are all within the frequency domain bandwidth configured for the current cell;

[0074] Step 4: The BWP-ID of the current scheduling is M1, then the next BWP-ID is M2. If M2 > maxNrofBWPs, execute Step 11; otherwise, execute Step 5;

[0075] Step 5: If N1_start < N2_start and N1_end > N2_start and N1_end < N2_end, execute Step 6; otherwise, execute Step 7;

[0076] Step 6: When the current BWP-ID = M1, allocate frequency domain resources starting from N1_start, and end the process;

[0077] Step 7: If N1_start > N2_start and N1_start < N2_end and N1_end > N2_end, then execute Step 8; otherwise, execute Step 9;

[0078] Step 8: When the current BWP-ID = M1, allocate frequency domain resources starting from N1_end, and end the process;

[0079] Step 9: If N1_start > N2_start and N1_start < N2_end and N1_end > N2_start and N1_end < N2_end, then execute Step 11; otherwise, execute Step 10;

[0080] Step 10: If N1_start < N2_start and N1_start < N2_end and N1_end > N2_start and N1_end > N2_end, then execute Step 11; otherwise, execute Step 12;

[0081] Step 11: When the current BWP-ID = M1, it can allocate frequency domain resources starting from N1_start or N1_end, and end the process;

[0082] Step 12: If the frequency domains of BWP-ID = M1 and BWP-ID = M2 do not overlap, then continue to judge the next BWP-ID, that is, M2 = M2 + 1, and re-execute Step 4.

[0083] The BWP frequency domain resource allocation system provided by the present invention will be described below. The BWP frequency domain resource allocation system described below can be correspondingly referred to the BWP frequency domain resource allocation method described above.

[0086] When there are multiple BWP frequency-domain resources overlapping, through a reasonable frequency-domain resource allocation method, the present invention can not only meet the service requirements within each BWP, but also improve the overall spectrum utilization rate of the cell, increase the cell throughput, and reduce the service delay.
