Description

1 TARIFF Public Network in Private 5G Area in Shared Spectrum Usage Suppression Method Technical Area The invention relates to the integration of a public mobile network and a local private 5G network. In the study model where the general (public) cells are structured within the same licensed spectrum, the specific cells are also included. Private 5G that prevents interference in private network service areas. guaranteeing the UL (upward transmission) / DL (downward transmission) performance of the network It relates to a method aimed at obtaining a guard band, a physical barrier. Efficient 10% of the spectrum without isolation or static power restrictions. It aims to utilize this without completely shutting down the public network. By suppressing service and RF (radio frequency) levels within a dedicated 5G service area. Simultaneous use of the spectrum will be ensured. State of the Art Currently, there are 15 publicly accessible stations in the same spectrum band. Operating both the public and private 5G networks in close proximity to each other provides a dual advantage. This is not possible due to the inability to provide directional isolation. This situation is dedicated (private). (as allocated) private 5G network eliminates the flexibility of implementation. removing, resource and interference management in a dynamically evolving network for a long time This is not possible in the short term. Spectrum is a high-cost component in networks. The inefficient use of the spectrum is a major problem. To solve the problem of inefficient resource and spectrum sharing, currently... possible solutions:  Using the guard band leads to spectrum waste. Furthermore, network continuity is compromised. It is not applicable in all circumstances because it is prone to malfunction.  Physical isolation is partially provided indoors for indoor applications. However, this is not possible in outdoor applications. 2  Static power constraints provide a solution to beam-based interference. It won't bring it.  Different TDD (Time Division Duplex) slots A CLI that kills UL performance when it comes to configuration usage. Interference (Cross-Link Interference) refers to the 5 is happening.  Even if a public cell does not provide service in its private area, SSB (Synchronization Signal) Block / Synchronization Signal Block), CSI-RS (Channel State Information Interference such as Reference Signal / Channel Status Information (Reference Signal), etc. Why does it happen? 10 In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion... Due to its shortcomings, an improvement is needed in the relevant technical field. It has been made. Purpose of the Invention The invention was created by drawing inspiration from existing situations and addressing the aforementioned drawbacks. 15 It aims to solve the problem. The invention aims to enable a public 5G network to dynamically recognize the private 5G service area. And it suppresses both service and physical RF sources in this area. Public Within the private 5G area recognized in the service-providing cell, PHY (Physical Layer) In the layer, SSB (Synchronization Signal Block / Synchronization Signal 20) (Block) beam shutdown, CSI-RS squelch, MAC (Medium Access Control) Assignment of PRB (Physical Resource Block) at the Control layer This is not done, UE at the RRC (Radio Resource Control) layer. (User Equipment) access requests are denied, RACH in accordance with UL guidelines. Suppression is applied to Random Access Channel (Random Access Channel) responses and 25 also public DL (down) corresponding to private 5G UL slots (directional) slots are closed by blanking the relevant area, thus preventing CLI interference. This can be prevented. To achieve the objectives described above, a public mobile network and local In the operating model where the private 5G network is built on the same licensed spectrum, the public sector receives 30 private, which prevents open cells from generating interference in private network service areas. A method aimed at guaranteeing UL / DL performance of a 5G network. 3 It has been improved, and the method uses a private network that the private user uses to access the network. a dedicated 5G terrestrial station operating in the field and providing connectivity via an air interface. To ensure the base station uses the spectrum efficiently: - By defining the dedicated service area of ​​the PZD module for the dedicated 5G base station. transmitting it to a base station providing public service, 5 - public service area recognizing private service area and service restricted area as defined by, - via the coordination interface: that any user device is within a service restricted area The calculation that it is not, 10 The failure to provide a RACH response to users in this area, RRC requests are rejected and call pagination messages are displayed in this area. not being published, He also mentioned the lack of SSB broadcasts in this area, the silencing of CSI RS, and DL. No PRB planning, 15 Emptying those TDD DL slots, blocking those publicly accessible UL slots in the private service area increasing public suppression as the load on the private network increases It includes the steps involved in the process. The structural and characteristic features and all the advantages of the invention are given in the figures below and 20 This becomes clearer thanks to the detailed explanation written with references to these figures. This will be understood, and therefore the evaluation should also take these forms and detailed explanations into consideration. It needs to be done by taking precautions. Figures that will help understand the invention. Figure 1 shows a representation of the elements involved in the realization of the method described in the invention. 25 It is a drawing. Explanation of Part References 1. Private 5G base station 2. PZD module 3. Coordination interface 30 4 4. Base station Detailed Description of the Invention In this detailed explanation, the preferred configurations of the method in question are described only. This is explained to facilitate a better understanding of the subject. - Private 5G base station (1), 5 used by a private user to access the network terrestrial operating in the private network area, connecting via an aerial interface. It is a station. - PZD (Private Zone Definition) module (2), private It defines the network service area and transmits it to the public station. Public. 10 that defines the area where the network's RF and service restrictions will be provided It is a module. - Coordination interface (3), RF and service on public network It manages its limitations. - Base station (4), used by the public user to access the network, It is a terrestrial station that provides a connection via the aerial interface. 15 In the method that is the subject of the invention, the PZD module (2) defines the special service area and makes it available to the public. Thus, it transmits to the base station (4) providing open service, thus the public service area is private It recognizes the service area and defines it as a service restricted area. Coordination interface (3), It calculates whether any user device is within a service-restricted area. This RACH responses are not given to users in this area, RRC requests are rejected, and calls in this area are blocked (20). Paging messages are not published. Similarly, SSB (Social Security Classification System) messages are not published in this area, CSI_RS (Call to Reference). It is silenced and the DL PRB (Physical Resource Block) is not planned. Additionally, TDD DL slots are vacated. Publicly accessible UL slots are blocked in a dedicated service area. This is done. As the private network load increases, public network suppression is increased. All these practices... The efficient 25 private 5G base station (1) is managed via the coordination interface (3). This allows the spectrum to be used in this way.
