Description

Resource allocation methods, storage media, electronic devices and computer program products

[0001] Cross-reference to related applications

[0002] This disclosure is based on and claims priority to Chinese patent application CN2024117585571, filed on November 29, 2024, entitled “Resource Allocation Method, Storage Medium, Electronic Device and Computer Program Product”, and incorporates the entire contents of that patent application by reference. Technical Field

[0003] This disclosure relates to the field of communications, and more specifically, to a resource allocation method, a storage medium, an electronic device, and a computer program product. Background Technology

[0004] In traditional wireless communication systems, frequency domain resources divide a frequency band into one or more carriers, and within each carrier, one or more bandwidth parts (BWPs). Figure 1 is a schematic diagram of the traditional frequency domain resource architecture. As shown in Figure 1, network devices determine BWPs no larger than BWmax as configurable BWPs for the UE based on the maximum bandwidth (BWmax) that a cell can support within the frequency band and the maximum number of bandwidth parts (BWPs) that can be configured for a user equipment (UE) within a carrier. However, for situations requiring the integration of multiple frequency band resources, carriers within or between frequency bands need to be configured for the UE using carrier aggregation, and each BWP within a carrier needs to be configured individually. Since uplink and downlink data scheduling for the UE is performed on active BWPs, higher-layer signaling needs to consider multiple scheduling methods and corresponding parameter configurations, including cross-frequency band, cross-carrier, and cross-BWP configurations, when configuring BWP resources, increasing scheduling complexity and latency.

[0005] Example 1: For low-latency bursty services, when large service packets arrive, cross-BWP or even cross-carrier scheduling needs to be initiated, taking into account parameters such as sub-carrier spacing (SCS), bandwidth, and resource location among the scheduled resources. This increases the scheduling complexity on the network side.

[0006] Example 2: In energy-constrained application scenarios, when a service arrives, it needs to switch to a larger BWP for processing, and after processing is complete, it needs to fall back to a smaller BWP. Frequent BWP switching leads to increased scheduling latency.

[0007] Example 3: In traditional communication systems, frequency domain resources in adjacent frequency bands need to be integrated through inter-band carrier aggregation, while frequency domain resources within a frequency band need to be integrated through intra-band carrier aggregation. With carrier aggregation, the transmission and measurement of common signals, the BWP configuration for each carrier, and the activation / deactivation of some carrier resources all require more refined design. This significantly increases scheduling complexity and fails to fully improve resource utilization efficiency.

[0008] There is currently no good solution to the above problems. Summary of the Invention

In another example, the transmission device 206 may be a Radio Frequency (RF) module, used for wireless communication with the Internet.

[0030] This embodiment provides a resource allocation method. Figure 3 is a flowchart illustrating the resource allocation method according to an embodiment of this disclosure. As shown in Figure 3, the process includes the following steps:

[0031] Step S302, the first network device divides the first resource group into a first number of bandwidth portion BWP units;

[0032] In step S304, the first network device allocates a second number of BWP units from the first resource group to the user equipment.

[0033] In this embodiment, the first resource group includes frequency domain resources of at least two frequency bands or frequency domain resources of at least two carriers, or the first number of BWP units are associated with the frequency domain resources of the at least two carriers. The second number is an integer greater than or equal to 1 and less than or equal to 256, and the second number is less than or equal to the first number.

[0034] By following the steps described above, frequency domain resources of different frequency bands or different carriers can be grouped together as a set of resources, and BWP resources in this set of resources can be directly scheduled. This eliminates the intermediate step from spectrum resource allocation to BWP resource allocation, reduces the complexity of cross-frequency band or cross-carrier frequency domain resource scheduling, solves the problem of high complexity and latency in BWP resource scheduling in related technologies, and achieves the effect of improving the efficiency of BWP resource configuration.

[0035] In one exemplary embodiment, the first network device may include a base station, core network elements, etc., but is not limited thereto.

[0036] In some embodiments, the BWP unit includes a BWP or a subcell, wherein the subcell includes a segment of bandwidth resources having the same order of magnitude or the same subcarrier spacing (SCS) configuration.

[0037] In embodiments of this disclosure, a carrier may also represent a carrier component, carrier element, etc. A subcell may represent at least one of a carrier component, a cell, or a group of BWPs, etc.

[0038] In some embodiments, step S304, in which the first network device allocates a second number of BWP units from the first resource group to the user equipment, may include the following steps:

[0039] Step A1: The first network device configures the user equipment to activate the second number of BWP units;

[0040] Step A2: The first network device schedules the user equipment to perform uplink and downlink data transmission within the frequency domain resource range corresponding to the activated BWP unit.

[0041] In this embodiment, the first network device can directly allocate BWP frequency domain resources to each user equipment and can schedule BWP resources from multiple frequency bands or multiple carriers, thereby improving the efficiency of frequency domain resource configuration.

[0042] In some embodiments, step S304, in which the first network device allocates a second number of BWP units from the first resource group to the user equipment, may include the following steps:

[0043] Step B1: The first network device allocates a second number of BWP units from the first resource group to the cell where the user equipment is located.

[0044] Step B2, the first network device configures the user equipment to activate some or all of the BWP units in the second number of BWP units;

[0045] Step B3: The first network device schedules the user equipment to perform uplink and downlink data transmission within the frequency domain resource range corresponding to the activated BWP unit.

[0046] In this embodiment, the first network device can directly allocate BWP frequency domain resources to the cell, and then select BWP resources for user equipment within the cell from the BWP frequency domain resources already allocated to the cell. This method further improves the configuration efficiency of frequency domain resources.

[0047] In some embodiments, the first resource group in step S302 includes at least one of the following:

[0048] Frequency band resources corresponding to frequency band range 1;

[0049] Frequency band resources within a first preset frequency range corresponding to the frequency band range 1;

[0050] Frequency band resources corresponding to frequency band range 2;

[0051] Frequency band resources within the second preset frequency range corresponding to the frequency band range 2.

[0052] In this embodiment, the frequency range is mainly divided based on the characteristics of different frequency bands and their applications in the network, in order to meet different network needs. Frequency Range 1 (FR1) and Frequency Range 2 (FR2) are the frequency ranges specified in 5G NR (New Radio). Frequency Range FR1 corresponds to a frequency range of 450MHz to 6000MHz, also known as the 5G Sub-6GHz band; Frequency Range FR2 corresponds to a frequency range of 24250MHz to 52600MHz, also known as the 5G millimeter wave band.

[0053] In one exemplary embodiment, the first preset frequency range corresponding to the frequency band range 1 may include: not higher than 1GHz, not lower than 1GHz and not higher than 2GHz, not lower than 2GHz and not higher than 3GHz, not lower than 3GHz and not higher than 4GHz, not lower than 4GHz and not higher than 5GHz, etc., and this disclosure is not limited thereto.

[0054] In one exemplary embodiment, the second preset frequency range corresponding to the frequency band range 2 may include: not less than 20 GHz and not more than 30 GHz, not less than 30 GHz and not more than 40 GHz, not less than 40 GHz and not more than 50 GHz, not less than 50 GHz and not more than 60 GHz, etc., and this disclosure is not limited thereto.

[0055] In this embodiment of the disclosure, by setting a first resource group, cross-band and cross-carrier frequency domain resource scheduling can be performed within a specified frequency band range. This eliminates the intermediate step from spectrum resource allocation to BWP resource allocation, reduces the complexity of cross-band or cross-carrier frequency domain resource scheduling, solves the problem of high scheduling complexity and latency of BWP resources in related technologies, and achieves the effect of improving the efficiency of BWP resource configuration.

[0056] Figure 4 is a schematic diagram (I) of BWP configuration based on the first resource group in an embodiment of this disclosure. As shown in Figure 4, the first resource group includes N BWPs, and each UE can be configured with at least one of the N BWPs.

[0057] In this embodiment, a UE can be configured with m active BWPs simultaneously, where m is an integer not less than 1 and not greater than n. The total bandwidth of the m active BWPs is not greater than the total bandwidth of the first resource group. The UE performs uplink or downlink transmission on the active BWPs. For example, if m = 128, the network device can configure the UE to simultaneously activate 128 downlink BWPs and schedule the UE to receive downlink data on these 128 active downlink BWPs.

[0058] In some embodiments, for uplink or downlink, when the number of active BWPs configured for the UE is greater than 1, the configured active BWPs may include a primary BWP and one or more secondary BWPs; wherein, the secondary BWPs may be located in different frequency bands, frequency ranges, carrier start positions, or point A parameters from the primary BWPs, wherein point A is the center frequency of Common Resource Block 0 (CRB0).

[0059] In other embodiments, for uplink or downlink, when the number of active BWPs configured on the UE is greater than one, the configured active BWPs may include one primary BWP and one or more sub-BWPs. The sub-BWPs share the same frequency band, frequency range, carrier start position, or point A as the primary BWP. The frequency domain resources corresponding to the sub-BWPs and the primary BWPs may overlap.

[0060] In this embodiment, for N BWPs, the BWP index configured for a UE can be an integer from 0 to N-1.

[0061] In some embodiments, for Time Division Duplexing (TDD) mode, the uplink BWP and downlink BWP can reside within one BWP or a group of BWPs, wherein one BWP or a group of BWPs includes at least one of n BWPs configured for the UE or m active BWPs configured for the UE. The uplink BWP and downlink BWP have the same starting frequency domain or RB position.

[0062] In one exemplary embodiment, when the UE does not perform uplink or downlink transmission on an active uplink or downlink BWP, the network device may indicate that the available frequency domain resources of the UE on the active uplink or downlink BWP are 0.

[0063] In some embodiments, for Frequency Division Duplexing (FDD) mode, the uplink BWP and downlink BWP are located within a set of BWPs, wherein the set of BWPs includes at least one of n BWPs configured for the UE or m active BWPs configured for the UE. The uplink BWP and downlink BWP correspond to different BWPs or BWP IDs within the set of BWPs in the first resource group.

[0064] In this embodiment, each BWP in the first resource group can be configured to one or more UEs.

[0065] Through the embodiments of this disclosure, uplink BWP and downlink BWP can be configured for UE within the first resource group, realizing cross-band and cross-carrier frequency domain resource scheduling, improving the flexibility of frequency domain resource scheduling, and UE performs uplink and downlink transmission on the configured active BWP, thereby improving the flexibility of data transmission.

[0066] Figure 5 is a schematic diagram (II) of BWP configuration based on the first resource group in this embodiment of the present disclosure. As shown in Figure 5, the first resource group includes N sub-cells, and each UE can be configured with at least one sub-cell among the N sub-cells.

[0067] In this embodiment, a sub-cell includes a complete bandwidth resource with the same order of magnitude / SCS configuration. A UE can be configured with a maximum of N sub-cells, where N is an integer not less than 1 and not greater than 256.

[0068] In this embodiment, a UE can be activated simultaneously for a maximum of P sub-cells, where P is an integer not less than 1 and not greater than N. The configurable sub-cell IDs for the UE range from 0 to N-1.

[0069] In some embodiments, when a UE is configured with a sub-cell, the UE can be configured with any portion of the frequency domain resources within the corresponding frequency domain resource range of the sub-cell. When the UE is configured to activate a segment of frequency domain resources within the sub-cell, the UE can perform uplink or downlink transmissions on that segment of frequency domain resources. When the frequency domain resources configured to activate the UE within the sub-cell are empty or 0, the UE does not perform uplink or downlink transmissions within that sub-cell.

[0070] In some embodiments, for TDD mode, the UE's uplink and downlink BWPs are located in the same subcell.

[0071] In other embodiments, for FDD mode, the UE's uplink and downlink BWPs are located in different sub-cells.

[0072] In this embodiment, each sub-cell in the first resource group can be configured to one or more UEs.

[0073] Through the embodiments of this disclosure, one or more sub-cells can be configured for the UE within the first resource group, realizing cross-band and cross-carrier frequency domain resource scheduling, improving the flexibility of frequency domain resource scheduling, and enabling the UE to perform uplink and downlink transmissions on the configured active BWP, thereby improving the flexibility of data transmission.

[0074] Figure 6 is a schematic diagram (III) of BWP configuration based on the first resource group in this embodiment of the present disclosure. As shown in Figure 6, the first resource group includes N BWPs, and each cell can be configured with at least one of the N BWPs.

[0075] In this embodiment, the UE can be configured with one or more BWPs from all BWPs associated with a cell. The BWP ID that the UE can configure ranges from 0 to N-1.

[0076] In this embodiment, the UE can be configured to activate multiple BWPs associated with a cell. The UE can simultaneously perform uplink or downlink transmissions on multiple active BWPs associated with a cell.

[0077] In some embodiments, the UE may be configured with a super cell, wherein a super cell includes at least one of the following: N BWPs in a first resource group, N-1 BWPs in a first resource group, BWPs in a first resource group excluding the BWP used for initial access, all BWPs in a frequency band, BWPs in a frequency band excluding the BWP used for initial access, all BWPs in a frequency band group, and BWPs in a frequency band group excluding the BWP used for initial access, etc.

[0078] Through the embodiments of this disclosure, one or more BWPs can be configured for a cell within a first resource group, realizing cross-band and cross-carrier frequency domain resource scheduling, improving the flexibility of frequency domain resource scheduling. The UE is configured to activate the BWP associated with the cell and perform uplink and downlink transmissions on the activated BWP, improving the flexibility of data transmission.

[0079] In some embodiments, the first resource group includes at least one BWP group or at least one BWP set, wherein each BWP group or each BWP set includes at least one BWP unit.

[0080] In this embodiment, different BWP groups / sets may include the same BWP / BWP unit / BWP with the same BWP ID, or they may include different BWP / BWP units / BWP with different BWP IDs. Each BWP unit in the first resource group may be associated with one or more BWP groups / sets.

[0083] In this embodiment of the disclosure, by re-dividing the first resource group into multiple BWP groups / sets, frequency domain resource scheduling can be performed on a BWP group / set basis, thereby improving the efficiency of frequency domain resource scheduling. Furthermore, the BWPs in the BWP group / set can be frequency domain resources of different frequency bands or different carriers, making resource scheduling more flexible.
