Description

Technical Field

[0001] This application relates to the field of wireless communication, and more particularly to a wireless communication method and base station. Background Technology

[0002] As the application scenarios of 5G to B services continue to expand, more and more services are beginning to utilize wireless networks for information transmission and related control functions. In enterprise operations, network anomalies can lead to incalculable losses; therefore, when a wireless network serves as a transmission channel for enterprise services, it typically requires extremely high reliability.

[0003] To enhance the reliability of wireless networks, 5G networks typically employ dual-frequency network technology for data transmission and control. During service operation, data is transmitted synchronously on networks using different frequency bands emitted by different base stations. This allows services to be carried on two different networks simultaneously, ensuring that if one network fails, services can continue to operate on the other. While effectively improving wireless network reliability, this introduces a new problem: wasting some air interface resources during normal service operation. Therefore, how to improve the utilization efficiency of air interface resources while ensuring wireless network reliability has become a pressing issue. Summary of the Invention

[0004] This application provides a wireless communication method and network device to improve the utilization efficiency of network resources.

[0005] The first aspect of this application provides a method for wireless communication, comprising:

[0006] The main base station obtains the first service request sent by the terminal. The first service request is a connection establishment request sent by the terminal to the base station. The first service request carries the resource bandwidth required for the transmission of the first service.

[0007] The main base station sends a first message to the terminal based on the resource bandwidth required for the transmission of the first service. The first message indicates that the first service is transmitted by the first cell and / or the second cell. The first cell is a cell created by the main base station, and the second cell is a cell created by the auxiliary base station. The second cell is an auxiliary cell of the first cell.

[0008] In a possible implementation of this application, after the primary base station creates a first cell and the secondary base station creates a second cell, and the primary base station receives a first service request sent by the terminal, it allocates a transmission cell for the first service based on the resource bandwidth required for the transmission of the first service, and sends a first message to the terminal. The first message indicates that the first service will be transmitted by the first cell and / or the second cell. The cell resources originally used for backup and the first cell, which serves as the primary cell, are merged to form a cell resource pool. The primary base station then uses the first cell to uniformly control the cell resource pool composed of the first and second cells, thereby improving the utilization efficiency of network resources while ensuring the reliability of the wireless network.

[0009] In one possible implementation of the first aspect, the method further includes: the main base station acquiring first control information sent by the auxiliary base station; and the main base station sending the first control information to the terminal.

[0010] In a possible implementation of this application, the primary base station obtains the first control information sent by the secondary base station through the Xn interface between the primary base station and the secondary base station, the core network, or the OM channel of network operation and maintenance management, and encodes the first control information before sending it to the terminal. This eliminates the need for control information transmission between the secondary base station and the terminal, reducing the second cell's demand for control channels and further improving the utilization efficiency of air interface resources.

[0011] In one possible implementation of the first aspect, the method further includes: the main base station acquiring a second service request sent by the terminal; when the capacity of the first cell and the second cell does not support the simultaneous transmission of the first service and the second service, the main base station allocates the first cell or the second cell for transmission of the second service after the first service has been completed.

[0012] In a possible implementation of this application, the main base station also receives a second service request. This means that two services need to be performed simultaneously, and the capacity of the first and second cells is insufficient to support simultaneous transmission. In this case, the main base station can randomly assign a first priority or a second priority to the first or second service, or allocate transmission channels to the first and second services sequentially according to the order in which the first and second service requests are received. This solves the problem of resource allocation for the first and second services when they cannot run in parallel, facilitating rapid assessment of the current scenario and improving work efficiency.

[0013] In one possible implementation of the first aspect, the first service has a high priority and the second service has a medium priority. In a possible implementation of this application, the first service has a high priority and the second service has a medium priority. This allows for the priority order of providing transmission services to be determined through priority ranking, facilitating better resource coordination.

[0014] In one possible implementation of the first aspect, the main base station allocates a first cell or a second cell for transmission of the first service, including: the main base station sorts the first service and the second service according to priority and obtains the sorting result; the main base station allocates a first cell or a second cell for transmission of the first service according to the sorting result.

[0015] In a possible implementation of this application, when the first service and the second service have a priority order, they can be sorted according to priority, and then the first service with higher priority can be provided with transmission services based on the sorting result. When the priority of the service is used as the basis for the order of wireless resource allocation, it is easier to meet more urgent needs in a more planned manner.

[0016] In one possible implementation of the first aspect, the first service is transmitted through the first cell, and the second service is transmitted through the second cell. When the second cell fails, the method further includes: the main base station obtaining the transmission progress of the second service; the main base station allocating the second service to the first cell for transmission, so that the terminal transmits in the first cell according to the transmission progress.

[0017] In a possible implementation of this application, when a first service is transmitted through a first cell and a second service is transmitted through a second cell, if the second cell fails, the main base station obtains the transmission progress of the second service through the Xn interface between base stations or the core network. When the first service completes its transmission in the first cell, the second service is allocated to the first cell for transmission. This enables cell handover through scheduling by the main base station when a cell fails, ensuring that services can still be transmitted normally even when a cell fails.

[0018] A second aspect of this application provides a base station, comprising:

[0019] The acquisition unit is used to acquire the first service request sent by the terminal. The first service request is a connection establishment request sent by the terminal to the base station. The first service request carries the resource bandwidth required for the transmission of the first service.

[0020] The sending unit is used to send a first message to the terminal according to the resource bandwidth required for the transmission of the first service. The first message indicates that the first service is transmitted by a first cell and / or a second cell. The first cell is a cell created by the main base station, and the second cell is a cell created by the auxiliary base station. The second cell is an auxiliary cell of the first cell.

[0021] In one possible implementation of the second aspect, the acquisition unit is further configured to acquire the first control information sent by the auxiliary base station from the main base station.

[0022] The sending unit is also used to send first control information to the terminal.

[0023] In one possible implementation of the second aspect, the acquisition unit is also used to acquire the second service request sent by the terminal;

[0024] The equipment also includes an allocation unit, used to allocate either the first cell or the second cell for transmission of the first service when the capacity of the first cell and the second cell is insufficient to support the simultaneous transmission of the first service and the second service.

[0025] In one possible implementation of the second aspect, the first business function has a high priority.

[0026] The second business has a medium priority.

[0027] In one possible implementation of the second aspect, the allocation unit is specifically used for:

[0028] Sort the first and second services according to priority to obtain the sorting results;

[0029] Based on the sorting results, the first service is assigned to either the first or second cell for transmission.

[0030] In one possible implementation of the second aspect, the first service is transmitted through the first cell, the second service is transmitted through the second cell, and when the second cell fails, the acquisition unit is also used to acquire the transmission progress of the second service.

[0031] The allocation unit is also used to allocate the second service to the first cell for transmission, so that the terminal can transmit in the first cell according to the transmission progress.

[0032] A third aspect of this application provides a base station, including a processor and a memory, wherein the memory is used to store computer programs or instructions, and the processor is used to call the computer programs or instructions stored in the memory, so that the network device performs the functions performed by the main base station in the first aspect and any possible implementation of the first aspect.

[0033] The fourth aspect of this application provides a computer-storeable medium including instructions that, when executed on a computer, cause the computer to perform the method of the first aspect or any possible implementation thereof. Attached Figure Description

[0044] This application provides a wireless communication method and network device to improve the utilization efficiency of air interface resources while ensuring the reliability of wireless networks.

[0045] To facilitate understanding of the improvements of the proposed solution compared to existing technologies, a brief introduction to the heterogeneous dual-frequency network technology is first provided. Please refer to... Figure 1 , Figure 1 This is an architecture diagram of a dual-frequency network provided in an embodiment of this application.

[0046] In a dual-frequency network architecture, base station A establishes cell A, and base station B establishes cell B. Cells A and B cover similar areas. A switch located in the shared coverage area of ​​cells A and B initiates service A. Customer premise equipment (CPE) A transmits service A to base station A via cell A, and simultaneously, CPE B transmits service A to base station B via cell B. Service A transmitted via base station A is then routed through the core network to the application server, and service A transmitted via base station B is also routed through the core network to the application server.

[0047] Since both cell A and cell B are transmitting service A simultaneously, the reliability of service A during transmission is guaranteed. If cell A or cell B experiences an anomaly, service A transmitted in the other cell can still operate normally. Although this ensures the reliability of service operation, it consumes a portion of air interface bandwidth as a backup resource, thus wasting bandwidth resources when both cells are functioning normally.

[0048] To address this issue, this application proposes using multi-spectrum collaborative aggregation technology to aggregate the aforementioned cell A and cell B. Upon receiving service A, the main base station allocates either cell A or cell B as the transmission channel for service A based on the current resource availability. When a cell fails, the main base station uses L1 scheduling to reallocate service A to another cell for continued data transmission.

[0049] In this way, while ensuring high service reliability, multiple spectrum resources are utilized to the maximum extent, improving the transmission efficiency of network resources in application scenarios with multiple spectrum resources and high reliability requirements.

[0050] Based on the aforementioned ideas, the proposed solution in this application is divided into different stages, and each stage is described in detail below:

[0051] 1. The primary base station is the cell for service allocation.

[0052] First, a brief introduction is given to how a terminal initiates a service transmission request and how a terminal establishes a data transmission connection with the cell. Please refer to [link / reference]. Figure 2 , Figure 2 This is a schematic flowchart of a wireless communication method provided in an embodiment of this application.

[0053] 201. The main base station creates the first cell;

[0054] The main base station uses carrier aggregation technology to create the first cell as the main cell. The main cell has uplink, downlink and control channels.

[0055] There is no explicit order between steps 201 and 202; the example of step 201 coming first is merely for illustration.

[0056] 202. The auxiliary base station creates a second cell;

[0057] The secondary base station creates a second cell, which is an auxiliary cell of the first cell. The first and second cells use different frequency bands for data transmission, and the first and second cells cover the same area.

[0058] Preferably, to maximize the shared coverage area of ​​the first and second cells, base stations with relatively close physical distances are typically selected as the primary and secondary base stations, respectively. It should be noted that this application embodiment does not limit the physical distance between the first and second cells; as long as the first and second cells share a common coverage area, it is acceptable.

[0059] Optionally, the second cell may have uplink / downlink channels and a control channel, or it may only have uplink / downlink channels. This embodiment does not impose specific limitations and can be configured according to actual needs.

[0060] It should be noted that there can be one or more secondary base stations and second cells. This embodiment uses one secondary base station and one second cell as an example to illustrate the scheme. In practical applications, there is no specific limit to the number of secondary base stations and second cells; they can be set according to the actual situation.

[0061] There is no explicit order between steps 201 and 202; the example of step 201 coming first is merely for illustration.

[0062] 203. The main base station obtains the first service request sent by the terminal;

[0063] After the main base station creates the first cell, it obtains the first service request sent by the terminal in broadcast form through the first cell. The first service request is the terminal's first service connection request, which carries the resource bandwidth required for the first service transmission.

[0064] Optionally, the first service request may also carry the service priority and / or total resources.

[0065] It should be noted that there is no restriction here on whether the first service request carries the service priority and / or the total amount of service resources. Whether the first service request needs to carry the service priority and / or the total amount of service resources can be determined according to actual needs.

[0066] 204. The main base station sends the first message to the terminal;

[0067] After receiving the first service request sent by the terminal, the main base station determines the resource bandwidth required for the first service transmission based on the first service request. It then determines whether the bandwidth of the first cell and the second cell meets the resource bandwidth requirements of the first service. If the resource bandwidth of both the first cell and the second cell is greater than the resource bandwidth required by the first service, the main base station allocates either the first cell or the second cell for data transmission of the first service. In this case, the first message indicates that the first service will be transmitted by either the first cell or the second cell.

[0068] If the resource bandwidth of the first cell is greater than the resource bandwidth required by the first service, the main base station allocates the first cell for data transmission for the first service. In other words, the first message indicates that the first service is transmitted by the first cell.

[0069] If the resource bandwidth of the second cell is greater than the resource bandwidth required by the first service, the main base station allocates the second cell for data transmission of the first service. In other words, the first message indicates that the first service is transmitted by the second cell.

[0070] If the resource bandwidth of both the first cell and the second cell is less than the resource bandwidth required by the first service, the main base station coordinates the first service, with the first cell and the second cell each carrying a portion of the resource bandwidth required by the first service to complete the transmission. The first message indicates that the first service is jointly undertaken by the first cell and the second cell.

[0071] It should be noted that the specific content of the first message needs to be tailored to the actual application scenario. This is just an example and does not impose any specific restrictions.

[0072] 205. The terminal establishes a data transmission connection with the first or second cell.

[0073] After receiving the first message sent by the main base station, the terminal establishes a data transmission connection with the first cell and / or the second cell based on the information carried in the first message, and begins to transmit information of the first service.

[0074] In this embodiment, the primary base station creates a first cell, and the secondary base station creates a second cell. After receiving a first service request from the terminal, the primary base station allocates a transmission cell for the first service based on the resource bandwidth required for its transmission and sends a first message to the terminal. The first message indicates that the first service will be transmitted by the first cell and / or the second cell. The cell resources originally used for backup and the primary cell are merged to form a cell resource pool. The primary base station manages the cell resource pool through the primary cell. When a fault occurs, the primary cell can switch the service to another cell for continued transmission. This improves the utilization efficiency of air interface resources while ensuring the reliability of the wireless network.

[0075] Second, the auxiliary base station transmits control information through the main base station.

[0076] To further improve the utilization efficiency of wireless resources, this application proposes that, since there is a physical connection between the main base station and the auxiliary base station via an Xn interface, control messages between the auxiliary base station and the terminal can be transmitted from the auxiliary base station to the main base station via the Xn interface. The main base station processes the first control information sent by the auxiliary base station obtained from the Xn interface and then sends it through the control channel of the first cell.

[0077] To facilitate understanding of the solutions proposed in the embodiments of this application, a brief introduction to the common 5G radio access network (RAN) system architecture is first provided. Please refer to [link / reference]. Figure 3 , Figure 3 This is an architecture diagram of a 5GRAN system provided in an embodiment of this application.

[0078] A typical 5G RAN system consists of a building baseband unit (BBU), a remote radio unit (RRU), and antennas. BBU1 and RRU1 are connected via a CPRI interface, and RRU1 and antenna 1 are connected via a radio line. BBU2, RRU2, and antenna 2 are connected sequentially, in the same way as BBU1, RRU1, and antenna 1. Multiple such connections can exist. BBU1 and BBU2 are connected via an Xn interface, which can be understood as multiple base stations communicating through the Xn interface. The core network is connected to each base station and service server via wired or wireless connections.

[0079] For details on how secondary base stations transmit information through the control channel of the primary base station, please refer to [link / reference needed]. Figure 4 , Figure 4 This is another flowchart illustrating the wireless communication method provided in an embodiment of this application.

[0080] 401. The primary base station receives the first control information sent by the secondary base station;

[0081] The primary base station obtains the first control information sent by the secondary base station from the secondary base station. Since different cells are located in different base stations, the primary base station's coordinated scheduling of the secondary base station is achieved, based on the need for communication between the primary and secondary base stations through an interface to complete information transmission. Here, the communication between the primary and secondary base stations can be achieved through the core network, the OM channel of network operation and maintenance management, or the Xn interface between base stations in the 3GPP RAN protocol.

[0082] It should be noted that in practical applications, communication can occur not only between the main base station and the auxiliary base station, but also between auxiliary base stations themselves. The specific communication methods described here are only examples, and in actual applications, they need to be used in accordance with the actual situation.

[0083] 402. The main base station sends the first control information to the terminal.

[0084] After acquiring the first control information, the primary base station encodes the first control information and sends the encoded first control information to the terminal. The uplink and downlink configurations of the first cell and the second cell are configured and managed through the first cell. The physical downlink control channel (PDCCH) is set in the primary cell, that is, it is sent by the primary base station. The other spectrum resources of the first cell and the second cell are used to form a physical downlink shared channel (PDSCH) and / or physical uplink shared channel (PUSCH) resource pool through carrier aggregation technology.

[0085] The PDCCH consists of a control channel (CCH) set in the first cell, a synchronization signal, and a PBCH block (SSB). Multiple cells of the primary and secondary base stations share this PDCCH to reduce the resources occupied by the control channel in other cells.

[0086] In this embodiment, the primary base station obtains the first control information sent by the secondary base station through the Xn interface between the primary and secondary base stations, encodes the first control information, and sends it to the terminal. The secondary base station and the terminal do not need to transmit control information, reducing the second cell's demand for control channels and further improving the utilization efficiency of air interface resources.

[0087] Unlike common carrier aggregation techniques, the cells in this application embodiment use an approach where uplink and downlink control channels are only configured in the primary cell, further conserving network resources. A brief introduction is given here using the downlink channel as an example; please refer to [link to relevant documentation]. Figure 5 , Figure 5 This is a schematic diagram of a carrier aggregation downlink channel provided in an embodiment of this application.

[0088] In this approach, CCH and SSB are set up in the primary cell, meaning that CCH and SSB are set up on the first cell. No control channel needs to be set up on the secondary cell. This means that all network resources of the second cell are used for data transmission, which further improves the network resource utilization rate of the second cell.

[0089] The same principle applies to uplink channel network resource merging. When the primary and secondary cells cover the same area, the channel quality of the secondary cell is measured using single-frequency mobility measurements of the primary cell. The channel quality of the secondary cell is calculated based on the time-frequency synchronization between frequency bands, and this channel quality is used to achieve the sharing of management and control channels between the primary and secondary cells. Please refer to [link / reference] for details. Figure 6 , Figure 6This is a schematic diagram of a carrier aggregation uplink channel provided in an embodiment of this application.

[0090] As shown in the diagram, Cell 1, Cell 2, and Cell 3 share the SSB located in Cell 1. Specifically, the SSB can carry the master information block (MIB) necessary for the terminal to perform cell search and access. It is important to note that the single SSB mode is highly dependent on inter-band synchronization calibration. If there are problems with time and frequency synchronization between frequency bands, Cell 1 cannot replace Cell 2 and Cell 3 in any of their functions.

[0091] 3. When the main base station experiences a cell failure, it will reallocate cells for services.

[0092] To ensure that a failure in one cell does not affect ongoing services, this application proposes that the main base station can manage the secondary base station to detect anomalies in the second cell, and then switch the transmission channel of services transmitted in the second cell to ensure normal service operation.

[0093] For detailed implementation methods, please refer to... Figure 7 , Figure 7 This is another flowchart illustrating the wireless communication method provided in an embodiment of this application. Based on the foregoing Figure 3 The 5G RAN architecture and showcased in the exhibition Figure 5 The downlink channel shown below, combined with... Figure 7 , Figure 7 This is a schematic diagram illustrating the cell fault handling process provided in an embodiment of this application, and it introduces the solution provided in this embodiment of the application:

[0094] 701. The terminal transmits the first service to the main base station through the first cell;

[0095] Once a connection has been established between the terminal and the main base station, the first service is transmitted to the main base station through the first cell, and the priority of the first service is high.

[0096] It should be noted that steps 701 and 702 are not necessarily sequential and can be performed simultaneously. This is only an example, and adjustments can be made based on specific application scenarios in actual applications. The priority of the first service is also only an example; the priority of the first service can be high, medium, or low. Furthermore, the naming of service priorities is only an example, and specific settings can be made according to actual application scenarios in actual applications.

[0097] 702. The terminal transmits the second service to the secondary base station through the second cell;

[0098] Once a connection has been established between the terminal and the secondary base station, the second service is transmitted to the secondary base station through the second cell, and the priority of the second service is medium.

[0099] It should be noted that steps 701 and 702 are not necessarily sequential and can be performed simultaneously. This is merely an example, and adjustments can be made based on specific application scenarios in actual applications. The priority of the second business is also just an example. The priority of the first business can be not only medium, but also high or low. Furthermore, the priority naming of the business is just an example, and specific settings can be made according to the actual application scenarios in actual applications.

[0100] 703. The main base station obtains the operating status of the second cell;

[0101] The main base station obtains the operating status of the second cell through the core network, the OM channel of network operation and maintenance management, or the Xn interface between base stations in the 3GPP RAN protocol. When the second cell is abnormal, step 704 is executed.

[0102] 704. The main base station obtains the transmission progress of the second service;

[0103] After the main base station detects an anomaly in the second cell, it learns the transmission progress of the second service through the core network, the OM channel of network operation and maintenance management, or the Xn interface between base stations in the 3GPP RAN protocol.

[0104] 705. The main base station allocates the second service to the first cell for transmission.

[0105] After the main base station learns of the anomaly in the second cell and has a grasp of the transmission progress of the second service, it allocates the second service to the first cell for continued transmission after the first service has been completed, according to the service priority.

[0106] In addition, when there are multiple secondary cells, and one of these cells experiences an anomaly, the primary base station will consider demand and the service-level agreement (SLA) to determine the specific resource scheduling method when performing a service handover. In this case, the primary base station will combine the service level, demand, and SLA of the currently running service to determine the specific resource scheduling method.

[0107] For example, even if the second service has a lower priority than the first service, the main base station will still prioritize the second service over the first service because the second service is about to time out, in order to avoid the adverse effects of the service timeout.

[0108] Apart from Figure 7 Please refer to the information shown in the image. Figure 8In cases where possible, there may be a third cell in a single cell service. When the second cell is abnormal, the main base station obtains the services that are being carried out in the first and third cells and learns that the service carried by the third cell is a low-priority service. At this time, the medium-priority service carried on the second cell can be directly switched to the third cell.

[0109] It should be noted that the specific examples here are only to demonstrate how to switch between services when different priority services fail. In actual applications, it is necessary to make judgments based on the actual situation.

[0110] Optionally, after determining that an anomaly has occurred in the second cell, the main base station can also report the anomaly to the core network and disable the second cell, or send a warning to the network administrator and disable the second cell, etc., to facilitate subsequent follow-up and resolution of the anomaly.

[0111] This application proposes that when the primary base station detects an anomaly in a cell transmitting a service, it obtains the transmission progress of the second service through the core network, the OM channel of network operation and maintenance management, or the Xn interface between base stations in the 3GPP RAN protocol. Then, it schedules available channel resources in the resource pool according to certain rules to meet the transmission requirements of the service. In this way, when an anomaly occurs, there is no need to stop ongoing data transmission in other wireless networks for anomaly investigation; a rapid response can be made to the anomaly to ensure the normal operation and transmission of services. This reduces the risk of system downtime after an anomaly occurs.

[0112] The wireless communication method provided in the embodiments of this application has been described above. The base station provided in this application will be described below from a structural perspective. Please refer to... Figure 9 , Figure 9 A schematic diagram of a base station provided in an embodiment of this application includes:

[0113] The acquisition unit 901 is used to acquire a first service request sent by the terminal, wherein the first service request is a connection establishment request sent by the terminal to the base station, and the first service request carries the resource bandwidth required for the transmission of the first service.

[0114] The sending unit 902 is configured to send a first message to the terminal according to the resource bandwidth required for the transmission of the first service. The first message indicates that the first service is transmitted by a first cell and / or a second cell, wherein the first cell is a cell created by a primary base station, and the second cell is a cell created by a secondary base station, and the second cell is a secondary cell of the first cell.
