Description

For example, the bandwidth of a New Radio (NR) cell (such as 5M) is extended to cover the bandwidth range of all Long Term Evolution (LTE) cells (such as 10M).

[0049] Currently, the smooth evolution of the current generation of mobile communication networks to the next generation of mobile communication networks generally refers to the smooth evolution from 4G to 5G. The development process of the smooth evolution from 4G to 5G includes the following stages:

[0050] In the first stage, the 4G system and the 5G system are used on a large scale, and 4G and 5G are different base stations.

[0051] In the second stage, 4G and 5G share the same site, including the use of common main control, common baseband, and common radio frequency units. At this time, although LTE and NR cells are built on the same main control board, baseband board, and radio frequency unit, the spectra occupied by the cells are independent and there is no overlapping area. However, the spectra occupied by LTE and NR cells are within the same frequency band supported by the radio frequency unit.

[0052] In the third stage, LTE and NR cells of 4G and 5G sharing the same site are built on the same main control board, baseband board, and radio frequency unit. There is an overlapping area between the spectrum of the NR cell and the spectrum of the LTE cell, and there is a spectrum sharing area. In the spectrum sharing area, there are three ratios of the utilization ratios of the physical resource blocks (PRBs) of LTE and NR, which are 10:0, 5:5, and 1:9. When the ratio is 10:0, LTE user traffic has an advantage. When the ratio is 5:5, the LTE and NR user traffic is similar. When the ratio is 1:9, NR user traffic has an absolute advantage.

[0053] In the fourth stage, 5G is in large-scale commercial use, and a smooth transition is achieved when it is statistically found that NR user traffic has an absolute advantage in the long term in the third stage.

[0054] The critical period for smooth transition is the third stage. The transition plan from 4G to 5G in the third stage is to expand the bandwidth of the NR cell in the second stage to cover the entire bandwidth range of the LTE cell. The spectrum sharing area is within the original LTE cell spectrum range, and the NR uniformly manages and shares the PRB resources. The LTE side needs to use resources according to the instructions from the NR side. The addition of the dynamic spectrum sharing (DSS) function brings reserved resources within the LTE cell spectrum range, which will cause the peak value of the LTE cell to decrease and reduce the user perception.

[0055] For example, Figure 1 is a schematic diagram of the existing solution for the transition from 4G to 5G, as Figure 1As shown, the initial state is that a 10M LTE cell and a 5M NR cell with co-located 4G and 5G are built on the same main control board, baseband board, and radio frequency unit. By transforming the cell to enable the DSS function (which means dynamic sharing of the same spectrum segment between LTE and NR), the bandwidth of the 5M NR cell is expanded from 5M to 15M, covering the spectrum bandwidth of the 10M LTE cell. There is a spectrum sharing area where the spectra of the two cells overlap. In the spectrum sharing area, there are three ratios of PRB utilization rates of LTE and NR, namely 10:0, 5:5, and 1:9. At the beginning (i.e., the initial stage of transition), the ratio is 10:0, and LTE user traffic is dominant; as the number of NR users increases, when the PRB utilization rate ratio of LTE and NR dynamically reaches 5:5, the LTE and NR user traffic is not much different; when the number of NR users continues to increase and the PRB utilization rate ratio of LTE and NR dynamically reaches 1:9, NR user traffic has an absolute advantage.

[0056] Due to the limited cell bandwidth, NR exclusively occupies 5M bandwidth. For NR, directly going from 5M bandwidth to 15M bandwidth may result in excessive waste of resources in the initial stage of transition. Moreover, the bandwidth of the 10M LTE cell remains unchanged, and the shared PRB resources are uniformly managed by NR. The shared PRB resources are allocated from the LTE cell bandwidth, and the LTE side needs to use resources according to the instructions from the NR side. The addition of the DSS feature brings reserved resources within the spectrum range of the LTE cell, which may lead to a decrease in the peak value of the LTE cell during the transition period and reduce the user perception of LTE users.

[0057] Based on the above technical problems, the embodiment of the present application proposes a spectrum sharing method. By expanding the spectrum bandwidths of the first cell and the second cell, a first spectrum area and a second spectrum area are obtained respectively. The second spectrum area includes the spectrum areas occupied by the spectrum bandwidths of the first cell and the second cell. Among them, the communication network to which the first cell belongs is the next-generation communication network of the communication network to which the second cell belongs. The first spectrum area is used as the spectrum sharing area, and according to the indication information of the second network device that provides communication services for the second cell, the first cell is instructed to schedule the shared resources in the first spectrum area of the first cell. By expanding the bandwidth, the throughput of the first cell and the second cell is increased, and in the initial stage of transition, the network device of the current generation communication network uniformly manages the shared resources, enhancing the user perception and improving the user experience, and reducing resource waste.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part rather than all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0059] Figure 2 is a schematic flowchart of the spectrum sharing method provided by the embodiments of this application. As Figure 2 shown, the embodiments of this application provide a spectrum sharing method, which includes:

[0060] Step 201: Expand the spectrum bandwidths of the first cell and the second cell to obtain a first spectrum region and a second spectrum region respectively; the second spectrum region includes the spectrum regions occupied by the spectrum bandwidths of the first cell and the second cell; the communication network to which the first cell belongs is the next-generation communication network of the communication network to which the second cell belongs.

[0061] Specifically, the second cell refers to a cell under the current generation of mobile communication network, and the first cell refers to a cell under the next-generation mobile communication network, that is, the communication network to which the first cell belongs is the next-generation communication network of the communication network to which the second cell belongs.

[0062] For example, the first cell is a 5G cell and the second cell is a 4G cell; or the first cell is a 6G cell and the second cell is a 5G cell.

[0063] In the embodiments of this application, both the first cell and the second cell are in the Frequency Division Duplexing (FDD) mode or both are in the Time Division Duplexing (TDD) mode, that is, within the same frequency band (FDD to TDD is across frequency bands). Spectrum sharing can be achieved only when there is an overlapping area in the spectra occupied by the first cell and the second cell.

[0064] In the initial stage of the transition, the communication networks to which the first cell and the second cell belong share the same site, and the first cell and the second cell are built on the same main control board, baseband board, and radio frequency unit. The spectrum bandwidth of the first cell is expanded to obtain a first spectrum region, and the spectrum bandwidth of the second cell is expanded to obtain a second spectrum region, and the second spectrum region covers the spectrum regions occupied by the spectrum bandwidths of the first cell and the second cell.

[0065] For example, during the initial transition period, a 10M LTE cell and a 5M NR cell sharing the same base station are built on the same main control board, baseband board, and radio frequency unit. By performing the first transformation on the cell, the DSS function is enabled. The bandwidth of the 5M NR cell is expanded from 5M to 10M, the bandwidth of the 10M LTE cell is expanded from 10M to 15M, and the 15M LTE cell is expanded to cover the spectrum bandwidth of the 10M NR cell.

[0066] Step 202: Use the first spectrum region as a spectrum sharing area, and indicate the shared resources scheduled by the first cell in the first spectrum region of the first cell through the indication information of the second network device. The second network device refers to the network device that provides communication services for the second cell.

[0067] Specifically, use the second spectrum region that has been expanded to cover the spectrum bandwidth of the first cell as the spectrum sharing area. The shared PRB resources are allocated from the NR cell bandwidth, and this shared resource is uniformly managed by the second network device. The shared resources that can be scheduled by the first cell in the first spectrum region of the first cell can be indicated through the indication information of the second network device, where the second network device is the network device that provides communication services for the second cell.

[0068] For example, Figure 3 is a schematic diagram of dynamic spectrum sharing for the example scenario provided in the embodiments of this application. As Figure 3 shown, during the initial transition period, the utilization ratios of PRBs for NR and LTE are very small. The initial LTE cell bandwidth is 10M, and the initial NR cell bandwidth is 5M. At this time, by performing the first transformation on the cell, the DSS function is enabled: the bandwidth of the 5M NR cell is expanded from 5M to 10M, and the bandwidth of the 10M LTE cell is expanded from 10M to 15M. Use the spectrum region occupied by the 10M NR cell bandwidth as the spectrum sharing area. The shared PRB resources are allocated from the NR cell bandwidth, and the shared PRB resources are uniformly managed by the LTE side. The NR side needs to use resources according to the indication of the LTE side.

[0069] The spectrum sharing method provided in the embodiments of this application expands the throughput of the first cell and the second cell by expanding the bandwidths of the first cell and the second cell, enhances the user perception of the current generation of mobile communication networks and the user perception of the next generation of mobile communication networks. Use the first spectrum region as the spectrum sharing area, and the network device of the current generation of mobile communication networks uniformly manages the shared resources in the spectrum sharing area, realizing the full utilization of resources during the initial transition period, reducing resource waste, and improving the perception and experience of users of the current generation of mobile communication networks.

[0070] In some embodiments, the method further includes:

[0071] When the utilization rate of the shared resources of the first spectrum region in the first cell is greater than that in the second cell, the first spectrum region is expanded to obtain a third spectrum region, and the second spectrum region is reduced to obtain a fourth spectrum region; the third spectrum region includes the spectrum regions occupied by the spectrum bandwidths of the first cell and the second cell.

[0072] The fourth spectrum region is used as a spectrum sharing area, and the shared resources scheduled by the second cell in the fourth spectrum region are indicated through the indication information of the first network device; the first network device refers to the network device that provides communication services for the first cell.

[0073] Specifically, when the utilization rate of the shared resources of the first spectrum region in the first cell is much greater than that in the second cell, that is, when the user traffic of the communication network to which the first cell belongs (i.e., the next-generation mobile communication network) increases and increases to the point where the user traffic of the communication network to which the first cell belongs is dominant for a long time, the first spectrum region is expanded to obtain a third spectrum region, and this third spectrum region covers the spectrum regions occupied by the spectrum bandwidths of the first cell and the second cell; and the second spectrum region is reduced to obtain a fourth spectrum region.

[0074] Then, the fourth spectrum region is used as a spectrum sharing area, and the shared resources scheduled by the second cell in the fourth spectrum region are indicated through the indication information of the first network device, where the first network device is the network device that provides communication services for the first cell.

[0075] For example, in the initial stage of the transition, after the first transformation of the cell to enable the DSS function, the LTE cell bandwidth is 15M and the NR cell bandwidth is 10M. The NR user traffic gradually increases. When the key performance indicator (KPI) monitors that the ratio of the PRB utilization rates of LTE and NR dynamically reaches 10:0 and the NR user traffic is dominant for a long time, the second transformation of the cell enables the DSS function: the 10M NR cell bandwidth is expanded from 10M to 15M, and the 15M LTE cell bandwidth is reduced from 15M to 10M. The 15M NR cell is expanded to cover the spectrum bandwidth of the 10M LTE cell. There is a spectrum sharing area where the two cell bandwidths overlap. The shared PRB resources are allocated from the LTE cell bandwidth and are uniformly managed by the NR side. The LTE side needs to use resources according to the indication of the NR side.

[0076] The spectrum sharing method provided by the embodiments of the present application, when it is monitored that the user traffic of the next-generation mobile communication network has long-term dominance in the late transition period, continues to expand the bandwidth of the first cell and reduces the bandwidth of the second cell, so that the bandwidth of the first cell covers the spectrum bandwidth of the second cell, expanding the throughput of the first cell, improving the user perception of the next-generation mobile communication network, and not affecting the user perception of the current-generation mobile communication network. The resources of the first cell and the second cell are fully utilized, realizing a smooth transition from the current-generation mobile communication network to the next-generation mobile communication network and improving the user experience.

[0077] In some embodiments, the method further includes:

[0078] Monitoring the utilization rate of the shared resources of the first cell for the first spectrum region and the utilization rate of the shared resources of the second cell for the first spectrum region.

[0079] Specifically, determining to start the DSS function is based on the ratio of the utilization rates of the shared resources of the first cell and the second cell for the spectrum sharing area. Therefore, it is necessary to monitor in real time the utilization rate of the shared resources of the first cell for the first spectrum region and the utilization rate of the shared resources of the second cell for the first spectrum region.

[0080] For example, in the smooth transition from 4G to 5G, the PRB utilization rate ratios of the NR cell and the LTE cell in the spectrum sharing area include three types: 10:0, 5:5, and 1:9. In the initial transition period, the ratio of the utilization rates of the shared resources of the NR cell and the LTE cell for the first spectrum region is 1:9, and the LTE user traffic is dominant, and the first DSS processing is performed. When the KPI monitors that the ratio of the utilization rates of the shared resources of the NR cell and the LTE cell for the first spectrum region is dynamically adjusted to 5:5, the LTE and NR user traffic is not much different. In the late transition period, when the KPI monitors that the ratio of the utilization rates of the shared resources of the NR cell and the LTE cell for the first spectrum region is dynamically adjusted to 10:0, the NR user traffic is absolutely dominant, and at this time, the second DSS processing is required.

[0081] The spectrum sharing method provided by the embodiments of the present application, by monitoring in real time the utilization rate of the shared resources of the first cell for the first spectrum region and the utilization rate of the shared resources of the second cell for the first spectrum region, can perform the second dynamic spectrum sharing in a timely manner when the user traffic of the next-generation mobile communication network is absolutely dominant, adjust the shared spectrum region and convert it to the next-generation communication network device to manage the shared resources, fully utilize the PRB resources of the first cell and the second cell, and improve the user perception and user experience.

[0082] In some embodiments, the shared resources for the first cell scheduling in the first spectrum region are determined by the second network device based on the utilization rate of the shared resources of the first spectrum region by the first cell and the utilization rate of the shared resources of the first spectrum region by the second cell.

[0083] Specifically, in the initial stage of the transition, the second network device uniformly manages the shared resources of the spectrum sharing area (the first spectrum region). After obtaining the utilization rate of the shared resources of the first spectrum region by the first cell and the utilization rate of the shared resources of the first spectrum region by the second cell monitored in real time, the second network device determines the range of shared resources available for the first cell / the first network device based on the utilization rates of the shared resources of the first spectrum region by the first cell and the second cell, and then indicates it to the second cell through indication information.

[0084] The spectrum sharing method provided by the embodiments of the present application, in the initial stage of the transition, the second network device determines the PRB range that the first cell can use in real time based on the utilization rates of the shared resources of the first spectrum region by the first cell and the second cell, realizing the management of the shared resources by the current generation of communication networks in the initial stage of the transition, and improving the user perception and user experience under the current generation of communication networks.

[0085] In some embodiments, the shared resources that prohibit the second cell scheduling in the first spectrum region are determined by the second network device according to the frequency point information of the first network device; and / or

[0086] The first spectrum region includes reserved resources; the reserved resources are used to carry information indicating the utilization situation of the shared resources.

[0087] Specifically, in the initial stage of the transition, the second network device uniformly manages the shared resources of the spectrum sharing area (the first spectrum region). Since the second cell cannot use the frequency domain position allocated to the first cell for occupancy, the second network device needs to determine the range of shared resources that prohibit the second cell scheduling in the first spectrum region according to the frequency point information of the first network device.

[0088] Specifically, the realization of the DSS function requires the common control resources of the first network device and the second network device to indicate the utilization situation of the resources, so that the resources can be better called. These common control resources will occupy some PRB resources in the shared spectrum area. Therefore, reserved resources need to be generated for use when the DSS is turned on for the first time in the initial stage of the transition, and the reserved resources are included in the first spectrum region.

[0089] In the late transition period, the first network device uniformly manages the spectrum sharing area (the fourth spectrum area). After obtaining the utilization rate of the shared resources of the first spectrum area by the first cell and the utilization rate of the shared resources of the first spectrum area by the second cell through real-time monitoring, the first network device determines the range of shared resources available for the second cell / second network device based on the utilization rates of the shared resources of the fourth spectrum area by the first cell and the second cell, and then indicates it to the second cell through indication information.

[0090] Optionally, in the late transition period, the first network device determines the range of shared resources in the fourth spectrum area that prohibits the first cell from scheduling according to the frequency point information of the second network device.

[0091] Optionally, in the late transition period, the second DSS activation requires reserved resources within the fourth spectrum area.

[0092] The spectrum sharing method provided by the embodiments of this application manages shared resources by the current generation of mobile communication network devices in the early transition period. The shared PRB resources are allocated from the bandwidth of the first cell, and the bandwidth of the first cell is expanded. Even if the DSS feature requires reserved resources within the spectrum range of the first cell, the throughput of the first cell is increased due to the doubling of the bandwidth, and the throughput of the second cell is also increased due to the increase in the bandwidth of the second cell. Therefore, this is equivalent to improving the user perception of the network-side users of the second cell and the network-side users of the first cell, and the resources of the second cell and the first cell are fully utilized in the early transition period. In the late transition period, when the traffic of the next generation of mobile communication network users dominates for a long time, the dynamic spectrum sharing processing method of the next generation of mobile communication network devices for managing shared resources is activated, realizing the smooth transition from the current generation of mobile communication network to the next generation of mobile communication network and improving the user experience.
