Description

Technical Field

[0001] The present application relates to the field of mobile communication technology, and in particular to a scheduling method, device, electronic device and computer-readable medium for a dynamic spectrum sharing network. Background Art

[0002] In order to achieve the goal of smooth evolution from 4G to 5G, multiple communication companies jointly developed a strategy to use 4G / 5G dynamic spectrum sharing on the 2.1GHz frequency to balance the 4G / 5G capacity, and jointly use the 40MHz large bandwidth to give full play to the 2.1G coverage advantage to achieve the 5G basic coverage layer and support the demand for 4G capacity growth in the existing network. Figure 1 As shown in the figure, using 40M NR+20MLTE (where 20M is the LTE / NR shared area), in the 40M DSS contiguous network, due to the LTE cell mod3 planning of the LNR shared bandwidth, the 40M DSS shared area will be subject to co-channel interference. Even if the LTE load is not high, due to the continuous transmission of CRS, the NR terminal at the cell boundary will still be subject to severe interference, which will cause the channel quality of the NR terminal to deteriorate and the bit error rate to increase when scheduling 40M bandwidth, so that the MCS downgraded terminal rate will drop significantly, and there is a high probability that it will drop to a level lower than the NR exclusive bandwidth scheduled for 20M.

[0003] Currently, most manufacturers use a dynamic frequency selection scheduling algorithm for optimization. That is, when the LTE interference is severe, the NR terminal only schedules 20M bandwidth of the exclusive spectrum. This will cause extreme waste of NR spectrum resources and a significant decline in 5G network performance. Currently, the industry needs an algorithm to allow NR terminals to schedule 40M bandwidth as much as possible while avoiding LTE CRS interference.

[0004] Therefore, a new scheduling method, device, electronic device and computer-readable medium for a dynamic spectrum sharing network are needed.

[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0032] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities.

These terms are used to distinguish one component from another component. Therefore, the first component discussed below can be referred to as the second component without departing from the teachings of the concepts of the present application. As used herein, the term "and / or" includes any one of the associated listed items and all combinations of one or more.

[0035] Those skilled in the art will appreciate that the drawings are merely schematic diagrams of example embodiments, and the modules or processes in the drawings are not necessarily necessary for implementing the present application, and therefore cannot be used to limit the scope of protection of the present application.

[0036] In the prior art, NR (New Radio) terminals are also called new air interfaces. Mobile communication systems are mainly composed of two subsystems: terminals, base stations, and core networks. The terminals and base stations form the base station subsystem, and many complex network elements inside the core network form the network subsystem. The terminal is generally a mobile phone, the base station is used to transmit signals, and the core network is similar to a router, connecting the base stations so that they can communicate with each other. Among them, the interface between the mobile phone and the base station is called an "air interface" because it is transmitted in the air between the base station and the mobile phone through electromagnetic waves. Regardless of whether the core network connected is 4G EPC or 5G 5GC, the same mobile phone has two air interface connections. The link with the 4G base station is the "old air interface", and the connection with the 5G base station is the "new air interface".

[0037] As mentioned above, the current optimization method of most manufacturers is to adopt a dynamic frequency selection scheduling algorithm, that is, when the LTE interference is serious, the NR terminal only schedules the bandwidth of 20M exclusive spectrum, which will cause the NR spectrum resources to be extremely wasted and the 5G network performance will be significantly reduced. In order to allow the NR terminal to schedule 40MHz as much as possible in the 40M DSS network, the present application can also go to the dynamic spectrum sharing network scheduling method to counteract the CRS interference in the 40M DSS contiguous networking. This method is based on a multi-spectrum rate matching algorithm. Multiple sets of rate matching spectra are prepared on the base station side. The terminal self-checks the interference and notifies the base station side. The base station matches the corresponding rate matching spectrum to the terminal, and the granularity of the time-frequency resources punched out by the spectrum is adaptive between the RE level and the symbol level. Using this method, the NR terminal can sacrifice a small amount of time-frequency resources to avoid CRS interference, so as to achieve the purpose of scheduling 40MHz large bandwidth performance is significantly better than scheduling 20MHz exclusive spectrum.

[0038] The following is a detailed description with reference to specific embodiments.

[0039] Figure 2 It is a system block diagram of a scheduling method and device for a dynamic spectrum sharing network according to an exemplary embodiment.

[0040] like Figure 2 As shown, the system architecture 20 may include NR terminal devices 201, 202, 203 and a base station 204. Users can use the NR terminal devices 201, 202, 203 to interact with other NR terminals or servers through the base station 204 to receive or send messages, etc. Various communication client applications, web browser applications, search applications, instant messaging tools, email clients, social platform software, etc. may be installed on the NR terminal devices 201, 202, 203.

[0041] NR terminal devices 201, 202, 203 can be various electronic devices with display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, etc.

[0042] NR terminal devices 201, 202, 203 can, for example, generate product information based on the product's own data; NR terminal devices 201, 202, 203 can, for example, generate enterprise information based on the product selling merchant data; NR terminal devices 201, 202, 203 can, for example, store the enterprise information in a block of the blockchain through a blockchain protocol and generate signature information; NR terminal devices 201, 202, 203 can, for example, generate product release information through the product information and the signature information.

[0043] For example, after detecting that the NR terminal accesses the dynamic spectrum sharing network, the base station 204 may allocate the first picture to the NR terminal for rate matching; for example, when receiving a spectrum number from the NR terminal, the base station 204 may allocate the second spectrum, the third spectrum, or the fourth spectrum corresponding to the spectrum number to the NR terminal for rate matching.

[0044] It should be noted that the scheduling method of the dynamic spectrum sharing network provided in the embodiment of the present application can be executed by the NR terminal devices 201, 202, 203 and the base station 204. Accordingly, the scheduling device of the dynamic spectrum sharing network can be set in the NR terminal devices 201, 202, 203 and the base station 204.

[0045] Figure 3 The flowchart of a method for scheduling a dynamic spectrum sharing network according to an exemplary embodiment is shown. The method 30 for scheduling a dynamic spectrum sharing network can be used for an NR terminal, and at least includes steps S302 to S308.

[0046] like Figure 3 As shown, in S302, the NR terminal accesses the dynamic spectrum sharing network and initiates a service. It also includes: the base station sends a first spectrum to the NR terminal; the NR terminal performs rate matching according to the first spectrum.

[0047] In S304, the signal to noise ratio of the NR terminal is obtained in real time. Signal to Interference plus Noise Ratio (SINR), signal to interference plus noise ratio refers to the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference).

[0048] In S306, when the signal-to-noise ratio is less than a threshold, the NR terminal performs a self-check to generate a spectrum number. The NR terminal performs a self-check based on the CRS-IC scheme to generate a spectrum number. Figure 4 The schematic diagram corresponding to the rate matching spectrum number 1, 2, 3, and 4 is shown as an example. Different boxes respectively show the channels in the area, which may include:

[0049] LTE PDCCH (Physical Downlink Control Channel) refers to the physical downlink control channel. PDCCH carries scheduling and other control information, including transmission format, resource allocation, uplink scheduling permission, power control, and uplink retransmission information.

[0050] LTE CRS Cell Reference Signal can be used for downlink channel quality measurement and downlink channel estimation, and is used for coherent detection and demodulation on the UE side. It is available in every downlink subframe and in the downlink pilot time slot of special subframes. In one RB, there is a reference signal every six subcarriers in the frequency domain and every three symbol bits in the time domain. The specific position arrangement is related to the CELLID.

[0051] CRS that is eliminated by rate matching;

[0052] PDSCH that can be used for NR, PDSCH (Physical Downlink Shared Channel) is one of the physical downlink channels in LTE. It is the downlink channel for LTE to carry main user data. All user data can be used, including system broadcast messages and paging messages that are not transmitted in PBCH. There is no specific physical layer paging channel in LTE.

[0053] More specifically, four sets of rate matching spectra for the 20M LNR shared area can be pre-stored on the base station side, as shown in the attached figure. Figure 4As shown. The available field vshift can record the position of CRS. Spectrum 1 shows the time-frequency resources corresponding to the CRS with vshift=0 on symbol 4 / 7 / 8 / 11 that is punctured by rate matching. Spectrum 2 shows the time-frequency resources corresponding to the CRS with vshift=0+vshift=2 on symbol 4 / 7 / 8 / 11 that is punctured by rate matching. Spectrum 3 shows the time-frequency resources corresponding to the CRS with vshift=0+vshift=1 on symbol 4 / 7 / 8 / 11 that is punctured by rate matching. Spectrum 4 shows the rate matching that punctures the entire 4 / 7 / 8 / 11 symbol. The base station does not send NR PDSCH at the punctured position in the spectrum, and the NR terminal does not decode PDSCH at the punctured position.

[0054] In one embodiment, when the CRS-IC self-test result meets the first strategy, a graph number 00 is generated, corresponding to graph 1; in one embodiment, when the CRS-IC self-test result meets the second strategy, a graph number 01 is generated, corresponding to graph 2; in one embodiment, when the CRS-IC self-test result meets the third strategy, a graph number 10 is generated, corresponding to graph 3; in one embodiment, when the CRS-IC self-test result meets the fourth strategy, a graph number 11 is generated, corresponding to graph 4.

[0055] Due to the existence of 20M LTE cell CRS, 40M DSS also needs to use spectrum 1 for rate matching to avoid CRS interference of the 40M DSS network itself when the signal-to-noise ratio is very high. The terminal self-checks the location of the interfering CRS of the neighboring cell through the CRS-IC solution, and reports a 2-bit spectrum number field to the base station through UCI. If the CRS-IC terminal self-checks that only vshift=0 is interfered, the spectrum number field 00 is reported. If vshift=0+vshift=2 is interfered, the field 01 is reported. If shift=0+vshift=2 is interfered, the field 10 is reported. If there are many shared areas in the surrounding areas and all are interfered, the field 11 is reported. The above situations correspond to rate matching spectrums 1-4 respectively.

[0056] In S308, the spectrum number is sent to the base station for scheduling the dynamic spectrum sharing network. The spectrum number is sent to the base station; the base station sends the second spectrum, the third spectrum, or the fourth spectrum to the NR terminal according to the spectrum number.

[0057] In one embodiment, the base station terminal needs to cooperate with the instructions of the NR terminal for processing, which may include, after detecting that the NR terminal accesses the dynamic spectrum sharing network, the base station allocates the first picture to the NR terminal for rate matching; when receiving the spectrum number from the NR terminal, the base station allocates the second spectrum, the third spectrum, or the fourth spectrum corresponding to the spectrum number to the NR terminal for rate matching.

[0058] According to the scheduling method of the dynamic spectrum sharing network of the present application, the dynamic spectrum sharing network is accessed through the NR terminal and a service is initiated; the signal-to-noise ratio of the NR terminal is obtained in real time; when the signal-to-noise ratio is less than a threshold, the NR terminal performs a self-check to generate a spectrum number; the spectrum number is sent to the base station to schedule the dynamic spectrum sharing network. In this way, the NR terminal can avoid CRS interference by sacrificing a small amount of time-frequency resources, realize dynamic spectrum sharing network scheduling, and solve the shortcomings of waste of spectrum resources and significant degradation of 5G network performance.

[0059] It should be clearly understood that the present application describes how to form and use specific examples, but the principles of the present application are not limited to any details of these examples. On the contrary, based on the teaching of the content disclosed in the present application, these principles can be applied to many other embodiments.

[0060] Figure 5 The present invention is a flowchart of a scheduling method for a dynamic spectrum sharing network according to another exemplary embodiment. Figure 5 The process 50 shown is for Figure 3 Detailed description of the process shown.

[0061] like Figure 5 As shown, in S501, the NR terminal accesses the 40M DSS network and starts the service.

[0062] In S502, the network matches rate matching map 1 to the NR terminal.

[0063] In S503, the SINR is greater than or equal to 10 dB.

[0064] In S504, the terminal starts a self-check, and reports a 2-bit field of the self-check result to the base station through the UCI.

[0065] In S505, when the self-check result is 00, the graph 1 is maintained and the SINR value is continuously monitored.

[0066] In S506, when the self-test result is 11, the base station configures spectrum 4 to the NR terminal through DCI.

[0067] In S507, when the self-check result is 10 or 01, the base station configures spectrum 2 or 3 to the NR terminal through DCI.

[0068] In S508, the SINR is greater than or equal to 5 dB.

[0069] In S509, the profile 4 is maintained and the SINR value is continuously monitored.

[0070] In S510, the terminal starts a self-test, and reports a 2-bit field of the self-test result to the base station through the UCI.

[0071] In S511, when the self-check result is 11, the graph 4 is maintained and the SINR value is continuously monitored.

[0072] In S512, the SINR is greater than or equal to 12 dB.

[0073] In S513, switch back to graph 1 without self-checking.

[0074] In S514, SINR is less than 4dB

[0075] In S515, switch back to Graph 4, no self-test required

[0076] In S516, profile 2 or 3 is maintained, and the SINR value continues to be monitored.

[0077] There are currently two methods to solve the CRS interference in 40M DSS: 1. Frequency selection scheduling algorithm, which schedules the 20M exclusive area, which will cause extreme bandwidth waste. 2. Rate matching method, which only removes the RE of the CRS of the 40M DSS itself, which will alleviate the interference, but serious interference may still occur.

[0078] The method proposed in this application can adaptively switch between RE-level rate matching and symbol-level rate matching. When the interference is weak, RE-level rate matching is used, and when the interference is strong, symbol-level rate matching is used. This greatly improves the spectrum efficiency while solving the interference problem.

[0079] The method proposed in this application can be used for outdoor contiguous 40M DSS networking. After using this method in the 40M DSS network, the NR terminal will reduce the interference caused by LTE CRS when scheduling a large 40M bandwidth, thereby achieving the effect of improving the average rate of the NR terminal and improving spectrum utilization.

[0080] Those skilled in the art will appreciate that all or part of the steps for implementing the above embodiments are implemented as a computer program executed by a CPU. When the computer program is executed by the CPU, the above functions defined by the above method provided in the present application are executed. The program may be stored in a computer-readable storage medium, which may be a read-only memory, a disk, or an optical disk, etc.

[0081] In addition, it should be noted that the above figures are only schematic illustrations of the processes included in the method according to the exemplary embodiments of the present application, and are not intended to be limiting. It is easy to understand that the processes shown in the above figures do not indicate or limit the time sequence of these processes. In addition, it is also easy to understand that these processes can be performed synchronously or asynchronously, for example, in multiple modules.
