Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to a resource allocation method, a resource allocation device, an electronic device, and a computer-readable storage medium. Background Technology

[0002] In the refarming scenario of the 800MHz Frequency Division Duplexing (FDD) band, considering that 800MHz is the large-scale foundational network for the wide coverage of Long Term Evolution (LTE) technology and the main bearer network for VoLTE (Voice Over LTE), a certain amount of bandwidth needs to be reserved for LTE and VoLTE in 800MHz. Therefore, Dynamic Spectrum Sharing (DSS) technology between 4G and 5G is the preferred technology for refarming the 800MHz FDD band.

[0003] Among the relevant technologies, there are two main schemes to achieve uplink DSS with a small bandwidth of 800M (such as 10M): Scheme 1: 10M New Radio (NR) + 5M LTE, that is, the maximum shared bandwidth of NR can reach 10M, the maximum shared bandwidth of LTE can reach 5M, and NR and LTE share bandwidth unequally; Scheme 2: 10M NR + 10M LTE, that is, the maximum shared bandwidth of NR can reach 10M, the maximum shared bandwidth of LTE can reach 10M, and NR and LTE share bandwidth equally.

[0004] However, the above two schemes cannot be dynamically changed according to the terminal service situation. There are also bandwidth compatibility issues between LTE terminals and NR terminals, and the Physical Uplink Control Channel (PUCCH) in the middle of the bandwidth causes fragmentation of the NR Physical Uplink Shared Channel (PUSCH), affecting the uplink rate of the terminal.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0014] In some embodiments of this disclosure, the shared resource segment of the LTE network and the NR network and the flexible resource segment of the LTE network and the NR network each account for half of the uplink shared bandwidth resources.

[0029] Figure 8 A structural block diagram of an electronic device according to an embodiment of the present disclosure is shown. Detailed Implementation

[0030] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0031] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0032] It should be noted that the ordinal numbers such as "first" and "second" mentioned in the embodiments of this disclosure are used to distinguish multiple objects, and are not used to limit the order, timing, priority or importance of multiple objects. Furthermore, the descriptions of "first" and "second" do not limit the objects to necessarily being different.

[0033] Dynamic spectrum sharing (DSS) technology enables dynamic spectrum sharing between 4G and 5G networks. It can meet the traffic needs of both 4G and 5G users on limited spectrum resources, achieving instant spectrum allocation and sharing through dynamic scheduling between 4G and 5G. DSS is the preferred technology for refarming the 800MHz FDD band, enabling more efficient use of the low-frequency 800MHz bandwidth spectrum resources and providing optimal performance for 4G and 5G devices.

[0034] The 800M small bandwidth uplink DSS solution in related technologies cannot be dynamically changed according to the terminal service situation, resulting in bandwidth compatibility issues between LTE terminals and NR terminals. Furthermore, the PUCCH in the middle of the bandwidth causes NR PUSCH fragmentation, affecting the terminal uplink rate.

[0035] Therefore, this disclosure provides a resource configuration scheme that configures uplink shared bandwidth resources as a shared resource segment between the LTE network and the NR network, and a flexible resource segment between the LTE network and the NR network. This scheme can configure the flexible resource segment between the LTE network and the NR network according to the service conditions of the NR terminal and the LTE terminal, thereby achieving the effect of dynamically adjusting the dynamic spectrum sharing uplink working mode, solving the terminal compatibility problem, and improving the terminal uplink rate.

[0036] Figure 1 A schematic diagram of an exemplary system architecture to which the resource configuration method of embodiments of the present disclosure can be applied is shown. Figure 1 A system 100 for supporting dynamic spectrum sharing between LTE and NR networks is shown. The system 100 may include an LTE network and an NR network overlaid on the LTE network.

[0037] The NR network covers an area of ​​101. The NR network includes a base station 102 (e.g., a gNB), which provides wireless services to NR terminals 103 within the coverage area 101. The base station 102 can communicate with the NR terminals 103 via a radio link 104 based on the NR radio access network protocol.

[0038] The coverage area of ​​the LTE network is 105. The LTE network includes base station 106 (e.g., eNB), which provides wireless services to LTE terminals 107 within the coverage area 105. Base station 106 can communicate with LTE terminals 107 via radio link 108 based on the LTE radio access network protocol.

[0039] NR terminal 102 and LTE terminal 107 can be devices with wireless transceiver capabilities or chips that can be installed in any device. They can also be referred to as user equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication equipment, user agent, or user device. In the embodiments of this application, the NR terminal and LTE terminal can be mobile phones, tablet computers, computers with wireless transceiver capabilities, virtual reality terminals, augmented reality terminals, wireless terminals in industrial control, wireless terminals in autonomous driving, etc., but are not limited to these.

[0040] Figure 1 In this diagram, the coverage area 101 of the NR network overlaps with the coverage area 105 of the LTE network. The NR and LTE networks can share the same spectrum, which can be achieved using DSS (Dynamic Spectrum Sharing) technology. DSS technology enables dynamic spectrum sharing between 4G and 5G networks, satisfying the respective traffic needs of 4G and 5G users on limited spectrum resources. By utilizing dynamic scheduling of 4G and 5G networks, it achieves instantaneous spectrum allocation and sharing, providing optimal system performance for both 4G and 5G terminals.

[0041] It should be understood that Figure 1 The number of base stations 102, 106, NR terminal 102 and LTE terminal 107 in the embodiments is merely illustrative, and the present disclosure can be extended to more base stations and terminals in NR and LTE networks.

[0042] Figure 2This is a flowchart illustrating a resource allocation method according to an exemplary embodiment. (Refer to...) Figure 2 The resource configuration method provided in this disclosure may include the following steps.

[0043] Step S201: Configure uplink shared bandwidth resources, wherein the uplink shared bandwidth resources include: shared resource segments between the LTE network and the NR network, and flexible resource segments between the LTE network and the NR network.

[0044] The uplink shared bandwidth resource is a spectrum segment shared by the LTE network and the NR network. The shared resource segment of the LTE network and the NR network can be configured as a spectrum shared by the LTE network and the NR network. The flexible resource segment of the LTE network and the NR network can be configured as a spectrum shared by the LTE network and the NR network or a spectrum exclusively used by the NR network, depending on the service requirements.

[0045] In an exemplary embodiment, the shared resource segment between the LTE network and the NR network and the flexible resource segment between the LTE network and the NR network each account for half of the uplink shared bandwidth resources.

[0046] In other words, in this embodiment of the disclosure, the uplink shared bandwidth resources include the shared resource segment of the LTE network and the NR network, and the flexible resource segment of the LTE network and the NR network, and the shared resource segment and the flexible resource segment each account for half of the uplink shared bandwidth resources.

[0047] For example, the uplink shared bandwidth resource is 800M with a small bandwidth of 10M. The shared resource segment between the LTE and NR networks is the upper 5M of the 10M, and the flexible resource segment between the LTE and NR networks is the lower 5M of the 10M. Or, to put it another way, the flexible resource segment between the LTE and NR networks is the upper 5M of the 10M, and the shared resource segment between the LTE and NR networks is the lower 5M of the 10M.

[0048] In an exemplary embodiment, a first LTE PUCCH is provided at a first boundary of the uplink shared bandwidth resource, and a second LTE PUCCH is provided at a second boundary of the uplink shared bandwidth resource; a first NR PUCCH is provided outside the first boundary of the uplink shared bandwidth resource, and a second NR PUCCH is provided outside the second boundary of the uplink shared bandwidth resource; the first LTE PUCCH is adjacent to the first NR PUCCH, and the second LTE PUCCH is adjacent to the second NR PUCCH.

[0049] In an exemplary embodiment, the first boundary is the upper boundary of the uplink shared bandwidth resource, and the second boundary is the lower boundary of the uplink shared bandwidth resource; or, the first boundary is the lower boundary of the uplink shared bandwidth resource, and the second boundary is the upper boundary of the uplink shared bandwidth resource.

[0050] Considering that NR has a smaller boundary guard band than LTE for the same bandwidth, the number of NR resource blocks (RBs) is 6% more than that of LTE. For example, with a bandwidth of 10 Mbps, LTE can occupy 50 RBs, while NR can occupy 53 RBs, NR having 3 more RBs than LTE. Therefore, an LTE PUCCH can be placed at the boundary of the uplink shared bandwidth resource, and an NR PUCCH can be placed outside the boundary of the uplink shared bandwidth resource, with the NR PUCCH adjacent to the LTE PUCCH. The LTE PUCCH occupies approximately 1-2 RBs, and the NR PUCCH occupies approximately 1-2 RBs.

[0051] Specifically, a first LTE PUCCH can be set at the first boundary of the uplink shared bandwidth resource, a second LTE PUCCH can be set at the second boundary of the uplink shared bandwidth resource, a first NR PUCCH can be set outside the first boundary of the uplink shared bandwidth resource, and a second NR PUCCH can be set outside the second boundary of the uplink shared bandwidth resource. The first LTE PUCCH is adjacent to the first NR PUCCH, and the second LTE PUCCH is adjacent to the second NR PUCCH.

[0052] Wherein, the first boundary is the upper boundary and the second boundary is the lower boundary; or, the first boundary is the lower boundary and the second boundary is the upper boundary.

[0053] In an exemplary embodiment, the shared resource segment between the LTE network and the NR network includes: an LTE Physical Random Access Channel (PRACH) and a first PUSCH. The first PUSCH is the physical uplink shared channel between the LTE network and the NR network; the LTE PRACH is adjacent to the first LTE PUCCH, and the first PUSCH is adjacent to the LTE PRACH.

[0054] As explained above, the shared resource segment between the LTE and NR networks can be configured to allow both networks to share spectrum, while the flexible resource segment can be configured to allow either shared spectrum or dedicated spectrum for the NR network, depending on service requirements. Therefore, the flexible resource segment between the LTE and NR networks may or may not support the LTE network. Thus, in this embodiment, the LTE PRACH is configured within the shared resource segment between the LTE and NR networks. The LTE PRACH occupies approximately 6 RBs.

[0055] In addition to the LTE PRACH, the shared resource segment between the LTE and NR networks may also include the first PUSCH, which is the shared uplink channel between the LTE and NR networks. Furthermore, the LTE PRACH is adjacent to the first LTE PUCCH, and the first PUSCH is adjacent to the LTE PRACH.

[0056] In an exemplary embodiment, the flexible resource segment of the LTE network and the NR network includes: NR PRACH and a second PUSCH; wherein, the NR PRACH is adjacent to the second LTE PUCCH, and the second PUSCH is adjacent to the NR PRACH.

[0057] As explained above, the shared resource segment between the LTE and NR networks can be configured to allow the LTE and NR networks to share spectrum, while the flexible resource segment can be configured to allow the LTE and NR networks to share spectrum or allow the NR network to exclusively use spectrum, depending on service requirements. Therefore, the flexible resource segment between the LTE and NR networks can support the NR network. Thus, in this embodiment, the NR PRACH is configured within the flexible resource segment of the LTE and NR networks. The NR PRACH occupies approximately 6 RBs.

[0058] In addition to the NR PRACH, the flexible resource segment of LTE and NR networks can also include a second PUSCH. The NRPRACH is adjacent to the second LTE PUCCH, and the second PUSCH is adjacent to the NR PRACH. The second PUSCH can be configured as a shared uplink channel for LTE and NR networks or a dedicated uplink channel for NR networks, depending on service requirements.

[0059] In an exemplary embodiment, the shared resource segment of the LTE network and the NR network can be set above the uplink shared bandwidth resource, and the flexible resource segment of the LTE network and the NR network can be set below the uplink shared bandwidth resource.

[0060] In this case, the first boundary is the upper boundary, the second boundary is the lower boundary, the first LTE PUCCH is set at the upper boundary of the uplink shared bandwidth resource, the second LTE PUCCH is set at the lower boundary of the uplink shared bandwidth resource, the first NRPUCCH is set outside the upper boundary of the uplink shared bandwidth resource, the second NR PUCCH is set outside the lower boundary of the uplink shared bandwidth resource, the LTE PRACH is adjacent to the first LTE PUCCH, the first PUSCH is adjacent to the LTE PRACH, the NR PRACH is adjacent to the second LTE PUCCH, and the second PUSCH is adjacent to the NR PRACH.

[0061] The channels are arranged in the following order from top to bottom: first NR PUCCH, first LTE PUCCH, LTE PRACH, first PUSCH, second PUSCH, NR PRACH, second LTE PUCCH, and second NR PUCCH.

[0062] In an exemplary embodiment, the flexible resource segment of the LTE network and the NR network can be set above the uplink shared bandwidth resource, and the shared resource segment of the LTE network and the NR network can be set below the uplink shared bandwidth resource.

[0063] In this case, the second boundary is the upper boundary, the first boundary is the lower boundary, the second LTE PUCCH is set at the upper boundary of the uplink shared bandwidth resource, the first LTE PUCCH is set at the lower boundary of the uplink shared bandwidth resource, the second NRPUCCH is set outside the upper boundary of the uplink shared bandwidth resource, the first NR PUCCH is set outside the lower boundary of the uplink shared bandwidth resource, the LTE PRACH is adjacent to the first LTE PUCCH, the first PUSCH is adjacent to the LTE PRACH, the NR PRACH is adjacent to the second LTE PUCCH, and the second PUSCH is adjacent to the NR PRACH.

[0064] The channels are arranged from top to bottom as follows: Second NR PUCCH, Second LTE PUCCH, NR PRACH, Second PUSCH, First PUSCH, LTE PRACH, First LTE PUCCH, and First NR PUCCH.

[0065] Figure 3 This is a schematic diagram illustrating the resource configuration of uplink shared bandwidth resources according to an exemplary embodiment. Figure 3 In this configuration, the uplink shared bandwidth resource is 10M. The shared resource segment between the LTE network and the NR network is above the uplink shared bandwidth resource, while the flexible resource segment between the LTE network and the NR network is below the uplink shared bandwidth resource. Both the shared resource segment and the flexible resource segment are 5M.

[0066] from Figure 3 As can be seen, the channels, from top to bottom, are: NR PUCCH, LTE PUCCH, LTE PRACH, First PUSCH, Second PUSCH, NR PRACH, LTE PUCCH, and NR PUCCH. The First PUSCH is shared by the LTE and NR networks; the Second PUSCH can be configured as a shared PUSCH for the LTE and NR networks, or a dedicated PUSCH for the NR network, depending on service requirements.

[0067] In this embodiment of the disclosure, the uplink shared bandwidth resources include the shared resource segment of the LTE network and the NR network and the flexible resource segment of the LTE network and the NR network. The LTE PUCCH is set at the boundary of the uplink shared bandwidth resources, and the NR PUCCH is set outside the boundary of the uplink shared bandwidth resources, so as to avoid setting the LTE PUCCH or NR PUCCH in the middle of the bandwidth and reduce NRPUSCH fragmentation.

[0068] Step S202: Obtain LTE terminal traffic volume and NR terminal traffic volume.

[0069] In this step, the traffic volume of LTE terminals and NR terminals in DSS cells is statistically analyzed over a period of time. A DSS cell can be understood as a cell with overlapping coverage between the LTE and NR networks.

[0070] Step S203: If the traffic volume of the LTE terminal is greater than or equal to the traffic volume of the NR terminal, configure the flexible resource segment of the LTE network and the NR network as a shared resource of the LTE network and the NR network.

[0071] If the traffic volume of LTE terminals is greater than or equal to that of NR terminals, then the flexible resource segments of the LTE network and the NR network will be configured to share spectrum between the LTE network and the NR network.

[0072] In an exemplary embodiment, configuring the flexible resource segment of the LTE network and the NR network as a shared resource for the LTE network and the NR network may include: configuring the flexible resource segment of the LTE network and the NR network as a resource segment supporting the LTE network. Wherein, the second PUSCH in the flexible resource segment of the LTE network and the NR network is a physical uplink shared channel shared by the LTE network and the NR network.

[0073] If the traffic volume of LTE terminals is greater than or equal to that of NR terminals, the flexible resource segments of the LTE and NR networks will be configured in LTE Enable mode. Specifically, the second PUSCH will be configured as a physical uplink shared channel between the LTE and NR networks.

[0074] Figure 4 This is a schematic diagram illustrating the resource configuration of uplink shared bandwidth resources according to yet another exemplary embodiment. Figure 4 In this configuration, the uplink shared bandwidth resource is 10 Mbps, and both the shared resource segment and the flexible resource segment are 5 Mbps. The shared resource segment between the LTE network and the NR network is above the uplink shared bandwidth resource, while the flexible resource segment between the LTE network and the NR network is below the uplink shared bandwidth resource.

[0075] The flexible resource segments of the LTE and NR networks are configured in LTE Enable mode, meaning that the flexible resource segments of the LTE and NR networks are configured to share spectrum.

[0076] from Figure 4 As can be seen, the channels in the following order from top to bottom are: NR PUCCH, LTE PUCCH, LTEPRACH, PUSCH shared by LTE and NR networks, PUSCH shared by LTE and NR networks, NR PRACH, LTEPUCCH, and NR PUCCH.

[0077] In this embodiment, when the traffic volume of the LTE terminal is greater than or equal to that of the NR terminal, the flexible resource segment of the LTE network and the NR network is configured to LTE Enable mode. That is, the LTE network and the NR network can share the spectrum in the flexible resource segment, so that the LTE and NR bandwidths are the same (for example, the bandwidth of both LTE and NR is 10M). This solves the problem of low access success rate of 800M LTE terminals in the current network when the system bandwidth is less than 10M. It eliminates NR PUSCH fragmentation and does not require NRPUSCH rate matching, reducing uplink resource consumption and loss, improving the uplink rate of NR terminals, improving resource utilization and system capacity, reducing the processing complexity, cost and power consumption of NR and LTE, and improving the compatibility of 800M LTE terminals. It improves the service and networking flexibility of the DSS system, ensures the performance of the DSS system and the terminal service experience, greatly improves the terminal user experience, and is conducive to the evolution to 5G.

[0078] Step S204: If the terminal traffic volume of the LTE network is less than that of the NR network, configure the flexible resource segment of the LTE network and the NR network as a resource exclusively for the NR network.

[0079] If the traffic volume of LTE terminals is less than that of NR terminals, then the flexible resource segments of the LTE network and NR network will be configured as exclusive spectrum for the NR network.

[0080] In an exemplary embodiment, configuring the flexible resource segment of the LTE network and the NR network as a resource exclusively for the NR network includes configuring the flexible resource segment of the LTE network and the NR network as a resource segment that does not support the LTE network. Wherein, the second PUSCH in the flexible resource segment of the LTE network and the NR network is a Physical Uplink Shared Channel exclusively for the NR network.

[0081] If the traffic volume of LTE terminals is less than that of NR terminals, the flexible resource segments of both the LTE and NR networks will be configured in LTE Disable mode. Specifically, the second PUSCH will be configured as a physical uplink shared channel exclusively for the NR network.

[0082] Figure 5 This is a schematic diagram illustrating the resource configuration of uplink shared bandwidth resources according to yet another exemplary embodiment. Figure 5 In this configuration, the uplink shared bandwidth resource is 10 Mbps, and both the shared resource segment and the flexible resource segment are 5 Mbps. The shared resource segment between the LTE network and the NR network is above the uplink shared bandwidth resource, while the flexible resource segment between the LTE network and the NR network is below the uplink shared bandwidth resource.

[0083] The flexible resource segments of the LTE and NR networks are configured in LTE Disable mode, meaning that the flexible resource segments of the LTE and NR networks are configured as exclusive spectrum for the NR network.

[0084] from Figure 5 As can be seen, the channels in the following order from top to bottom are: NR PUCCH, LTE PUCCH, LTEPRACH, PUSCH shared by LTE and NR networks, PUSCH exclusively used by NR network, NR PRACH, LTE PUCCH, and NRPUCCH.

[0085] In this embodiment, when the traffic volume of LTE terminals is less than that of NR terminals, the flexible resource segment of both the LTE and NR networks is configured in LTE Disable mode. This means the NR network can exclusively use spectrum in the flexible resource segment, enabling existing 800MHz LTE terminals to be configured with shared uplink bandwidth (e.g., 10MHz). The low-bandwidth DSS system actually restricts uplink scheduling for LTE terminals to the shared resource segment (e.g., 5MHz), resolving the bandwidth compatibility issue for existing 800MHz LTE terminals. Furthermore, it reduces NR PUSCH fragmentation and eliminates the need for NR PUSCH rate matching, reducing uplink resource consumption and losses, improving NR terminal uplink speed, resource utilization, and system capacity. It also reduces the complexity, cost, and power consumption of NR and LTE processing, improving 800MHz LTE terminal compatibility. Additionally, it reduces the complexity, cost, and power consumption of NR terminal uplink processing, ensuring NR terminal uplink speed and service experience, improving resource utilization and system capacity, and significantly enhancing the end-user experience, which is beneficial for the evolution to 5G.

[0086] In an exemplary embodiment, after configuring the flexible resource segments of the LTE network and NR network as shared resources of the LTE network and NR network or exclusive resources of the NR network according to the terminal service situation, the traffic volume of LTE terminals and NR terminals can be further counted, and the configuration of the flexible resource segments of the LTE network and NR network can be changed according to the count results.

[0087] Figure 6This is a flowchart illustrating a resource allocation method according to yet another exemplary embodiment. For example... Figure 6 As shown, resource configuration can be achieved by following these steps.

[0088] Step S601: Initialize uplink shared bandwidth resources, set up LTE PUCCH at the boundary, and set up NRPUCCH outside the boundary, wherein the uplink shared bandwidth resources are 10M.

[0089] Step S602: Calculate the LTE terminal service volume and NR terminal service volume over a period of time.

[0090] Step S603: Determine whether the statistical LTE terminal service volume is greater than or equal to the statistical NR terminal service volume. If yes, proceed to step S604; otherwise, proceed to step S607.

[0091] Step S604: Determine that the DSS uplink working mode is a shared segment mode between two LTE networks and the NR network.

[0092] Step S605: Configure the upper 5M of the uplink shared bandwidth resource as a shared resource segment between the LTE network and the NR network.

[0093] Step S606: Configure the lower 5M of the uplink shared bandwidth resources to LTE Enable mode, that is, the LTE network and the NR network share the spectrum.

[0094] Step 607: Determine the DSS uplink working mode as a shared segment between the LTE network and the NR network + a dedicated segment for the NR network.

[0095] Step S608: Configure the upper 5M of the uplink shared bandwidth resource as a shared resource segment between the LTE network and the NR network.
