Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to wireless devices, resource management methods, and communication systems. Background Art

[0002] A shared network means that multiple operators use the same set of infrastructure or network resources (for example, basic equipment or network resources built by a certain operator) to communicate with terminal devices in order to reduce the cost of network infrastructure construction.

[0003] Currently, the main way for operators to share networks is through radio access networks sharing (RAN Sharing). Figure 1A As shown, the primary operator provides the radio equipment controller and radio equipment in the base station system. Other operators connect to the radio equipment controller in the primary operator's base station system through their respective core network equipment. Other operators need to use the network management equipment connected to the primary operator to manage the resources in the shared radio equipment.

[0004] Because the wireless device controller in the base station system can only be managed by the primary operator's network management equipment, other operators do not have management authority over the base station system. When other operators need to perform operations such as resource application, carrier establishment, network monitoring, fault handling, and configuration changes, they must rely on the primary operator's network management equipment to perform the corresponding operations. This means that the primary operator's network management equipment sends a message to the primary operator's wireless device controller, which then sends a message to the wireless device to apply for or manage wireless resources. Therefore, the access network sharing method used in traditional technologies seriously affects the processing efficiency of other operators' wireless device controllers in a series of operations, such as resource application, carrier establishment, network monitoring, fault handling, and configuration changes. Summary of the Invention

[0005] The present application provides a wireless device, a resource management method, and a communication system, which are used to enable multiple wireless device controllers to independently manage the physical resources in the wireless device while sharing the physical resources in the same wireless device.

[0006] In a first aspect, the present application provides a wireless device connected to at least two wireless device controllers via a fronthaul interface. The wireless device mainly includes an interface module and a processing module.

[0007] The interface module is used to obtain a carrier establishment request from a first wireless device controller, where the first wireless device controller is one of at least two wireless device controllers connected to the wireless device. The carrier establishment request is used to request establishment of a first carrier of the first wireless device controller.

[0008] Furthermore, the processing module is configured to determine first physical resource information based on the carrier establishment request, and determine whether to establish the first carrier based on the first physical resource information and physical resources corresponding to the first wireless device controller in the wireless device. The first physical resource information indicates physical resources required to establish the first carrier, and the at least two wireless device controllers correspond to different physical resources in the wireless device.

[0009] It should be noted that the interface module of the wireless device in the conventional technology is only connected to one wireless device controller (ie, the wireless device controller of the primary operator). Therefore, the interface module in the wireless device in the conventional technology cannot obtain carrier establishment requests from other wireless device controllers.

[0010] In addition, in the present application, in addition to being able to connect to at least two wireless device controllers, the wireless device can also obtain the physical resources corresponding to each wireless device controller, and the at least two wireless device controllers correspond to different physical resources in the wireless device. Therefore, after receiving the carrier establishment request, the wireless device can determine whether the resources indicated by the first physical resource information are sufficient to establish the first carrier based on the physical resources corresponding to the first wireless device controller (the wireless device controller that sent the carrier establishment request), without utilizing the physical resources corresponding to other wireless device controllers. Therefore, it is possible to achieve the aforementioned multiple wireless device controllers independently managing the physical resources in the wireless device. In addition, while achieving multiple wireless device controllers sharing one wireless device, it is possible to improve the flexibility of the wireless device controllers in managing the corresponding wireless devices.

[0011] In one possible implementation, the wireless device further includes a storage module. The storage module may be coupled to the processing module or may be independent of the processing module. The storage module is configured to store a first resource table including physical resources corresponding to each of the at least two wireless device controllers.

[0012] Exemplarily, the wireless device is connected to a first wireless device controller and a second wireless device controller. The first wireless device controller is one of the at least two wireless device controllers connected to the wireless device, and the second wireless device controller is the other of the at least two wireless device controllers connected to the wireless device. In this case, the first resource table stored in the storage module includes physical resources corresponding to the first wireless device controller and physical resources corresponding to the second wireless device controller. The physical resources corresponding to the first wireless device controller include multiple physical resources such as frequency band resources, power resources, channel resources, and carrier resources, and the physical resources corresponding to the second wireless device controller also include multiple physical resources such as frequency band resources, power resources, channel resources, and carrier resources.

[0013] Optionally, the first resource table further includes the types of physical resources that each wireless device controller is allowed to use, and the resource quantity of each physical resource or the resource attributes of each physical resource.

[0014] It should be understood that the physical resources corresponding to each wireless device controller in the aforementioned first resource table can be manually pre-allocated or dynamically allocated by the wireless device. For example, the first resource table can be manually input into a storage module of the wireless device; or the first resource table can be manually input into one of the at least two wireless device controllers connected to the aforementioned wireless device. The wireless device controller then sends the first resource table to the wireless device, which then stores the first resource table in the storage module. This application does not limit the implementation method for the wireless device to obtain the first resource table. It should be understood that regardless of which of the aforementioned implementation methods is adopted, the physical resources corresponding to different wireless device controllers are determined, and the processing module in the wireless device can only allocate the physical resources corresponding to the first wireless device controller to the first wireless device controller for use.

[0015] In conventional technology, since the primary carrier's radio device controller requests resources from the wireless device, the wireless device is unaware of which carrier's carrier the physical resources requested by the primary carrier's radio device controller are used to establish. Therefore, conventional wireless devices lack the aforementioned first resource table. This application stores a first resource table in the wireless device that records the physical resources corresponding to each radio device controller. This allows the physical resources in the wireless device to be divided among at least two radio device controllers connected to the wireless device, allowing the wireless device to use the physical resources corresponding to each radio device controller during the carrier establishment phase. This helps ensure that resource allocation in the wireless device does not conflict.

[0016] In one possible implementation, the carrier establishment request includes an identifier of the first wireless device controller, where the identifier of the first wireless device controller is used to indicate a request for physical resources corresponding to the first wireless device controller. The processing module is further configured to query the first resource table for the physical resources corresponding to the first wireless device controller based on the identifier of the first wireless device controller.

[0017] In this embodiment, it is proposed that the processing module can query the physical resources corresponding to the first wireless device controller in the first resource table based on the identifier of the first wireless device controller, which is conducive to ensuring the accuracy of the wireless device querying the physical resources corresponding to the first wireless device controller.

[0018] Optionally, if the information of physical resources corresponding to different wireless device controllers in the first resource table is stored in different storage locations, the processing module can only query the storage page of the physical resources corresponding to the first wireless device controller based on the identifier of the first wireless device controller, without traversing the storage location of the entire first resource table.

[0019] In a possible implementation, the processing module includes a central control module and at least two service processing modules, and the at least two wireless device controllers correspond one-to-one to the at least two service processing modules.

[0020] The central control module is configured to determine a first service processing module corresponding to the first wireless device controller from the at least two service processing modules according to the identifier of the first wireless device controller in the carrier establishment request, and transmit the carrier establishment request to the first service processing module.

[0021] The first service processing module is configured to determine the first physical resource information according to the carrier establishment request and transmit the first physical resource information to the central control module. The central control module then determines whether to establish the first carrier according to the first physical resource information and the physical resource corresponding to the first wireless device controller.

[0022] In this embodiment, the processing modules are divided into two categories: control modules (i.e., central control modules) and service modules (i.e., at least two service processing modules). Because each of the at least two service processing modules is independent of one another and corresponds to a wireless device controller, each service processing module can independently process messages (e.g., carrier establishment requests) for its corresponding wireless device controller. Compared to a solution where only one service processing module processes messages from different wireless device controllers, this not only improves service processing efficiency but also facilitates diversified service processing within a wireless device and independent updating and maintenance of each service processing module. Furthermore, when multiple wireless device controllers connected to a wireless device belong to different carriers, the wireless device can run service processing modules (also understood as service processing software) for different carriers, facilitating the generation of different carriers that meet the needs of each carrier within the wireless device based on the different service processing modules.

[0023] In one possible implementation, the wireless device further includes a carrier establishment module. The central control module is specifically configured to: when the amount of physical resources indicated by the first physical resource information is less than the amount of physical resources corresponding to the first wireless device controller, determine that establishment of the first carrier is permitted, and transmit the first physical resource information to the carrier establishment module. The carrier establishment module is configured to establish the first carrier using the physical resources indicated by the first physical resource information.

[0024] In a possible implementation manner, the central control module is further configured to update the amount of physical resources corresponding to the first wireless device controller in the first resource table according to the amount of physical resources indicated by the first physical resource information.

[0025] In a possible implementation, the central control module is specifically configured to:

[0026] When the amount of physical resources indicated by the first physical resource information is greater than the amount of physical resources corresponding to the first wireless device controller, sending a first notification message to the first service processing module, where the first notification message is used to indicate that the physical resources corresponding to the first wireless device controller are insufficient to establish the first carrier;

[0027] The first service processing module is further configured to control the interface module to send a carrier establishment response to the first wireless device controller, where the carrier establishment response is used to indicate that the first carrier establishment has failed.

[0028] In a possible implementation manner, the carrier establishment request further includes a first carrier parameter, where the first carrier parameter is used to indicate a feature of the first carrier.

[0029] The first service processing module is specifically configured to generate the first physical resource information based on the first carrier parameter and a preset rule corresponding to the first wireless device controller, wherein different wireless device controllers among the at least two wireless device controllers correspond to different preset rules, and the first physical resource information includes information on at least one of frequency band resources, power resources, channel resources, carrier resources, and number of stream resources.

[0030] In one possible implementation, the wireless device may also query for usage information of physical resources corresponding to one of the at least two wireless device controllers based on wireless device controller granularity. This query process involves the interface module, the central control module, and the first service processing module (i.e., the service processing module corresponding to the wireless device controller to be queried).

[0031] Specifically, the interface module is further configured to receive a resource query message from the first wireless device controller, the resource query message being used to query usage information of physical resources corresponding to the first wireless device controller, the resource query message including an identifier of the first wireless device controller. The central control module is then further configured to transmit the resource query message to the first service processing module corresponding to the first wireless device controller based on the identifier of the first wireless device controller. The first service processing module is then further configured to query usage information of the physical resources corresponding to the first wireless device controller. The interface module is then further configured to send usage information of the physical resources corresponding to the first wireless device controller to the first wireless device controller.

[0032] In this embodiment, each service processing module can query the physical resource usage information of a specific wireless device controller and provide feedback to the wireless device controller. This helps prevent wireless devices from misreporting the physical resource usage of a wireless device controller to other wireless device controllers and improves the accuracy of the physical resource usage information queried by wireless devices for each wireless device controller.

[0033] In one possible implementation, the wireless device can also feedback fault information based on the granularity of the wireless device controllers, that is, feedback fault information to some of the at least two wireless device controllers connected to the wireless device. The fault feedback process involves the interface module and the central control module.

[0034] The central control module is configured to obtain fault information indicating a physical resource in the wireless device that has experienced a fault. The central control module then determines at least one second wireless device controller from the at least two wireless device controllers, the second wireless device controller being the wireless device controller that uses the physical resource indicated by the fault information. The central control module then controls the interface module to transmit the fault information to the second wireless device controller.

[0035] In this embodiment, the wireless device can also provide fault feedback based on the granularity of the radio device controller. Specifically, the wireless device can determine which radio device controllers are affected by the faulty physical resource. The wireless device then provides fault information only to the affected radio device controllers, rather than to all radio device controllers connected to the wireless device.

[0036] In a possible implementation, the interface module is further configured to obtain a resource configuration message, where the resource configuration message includes the first resource table.

[0037] In this embodiment, since the wireless device and the wireless device controller are not necessarily located in the same geographical location (for example, the wireless device is often located on a signal tower, and the device controller does not need to be located in the base station's computer room), the first resource table is sent to the aforementioned wireless device through a wireless device controller connected to the wireless device. This is beneficial to improving resource allocation efficiency, avoiding manual configuration on the signal tower, and helping to reduce the complexity of operation and maintenance management.

[0038] In a second aspect, the present application provides a first wireless device controller, which is one of at least two wireless device controllers connected to a wireless device. The first wireless device controller includes: a processing module and an interface module.

[0039] Among them, the processing module is used to generate a carrier establishment request, the carrier establishment request is used to request to establish the first carrier of the first wireless device controller, the carrier establishment request includes the identifier of the first wireless device controller, the identifier of the first wireless device controller is used to indicate an application for physical resources corresponding to the first wireless device controller in the wireless device, and the at least two wireless device controllers correspond to different physical resources in the wireless device; the interface module is used to send the carrier establishment request to the wireless device.

[0040] Optionally, the identifier of the first wireless device controller carried in the carrier establishment request is used by the wireless device identifier to query the physical resources corresponding to the first wireless device controller in the first resource table.

[0041] In this embodiment, any of the multiple wireless device controllers connected to the wireless device can send a carrier establishment request to the wireless device, requesting the establishment of a first carrier using the physical resources corresponding to the first wireless device controller in the wireless device. This enables the multiple wireless device controllers to independently manage the physical resources in the wireless device. This allows multiple wireless device controllers to share a single wireless device, while also increasing the flexibility of the wireless device controllers in managing the wireless device.

[0042] In a third aspect, the present application provides a resource management method performed by a wireless device connected to at least two wireless device controllers. In this method, the wireless device may obtain a carrier establishment request from a first wireless device controller, which is one of the at least two wireless device controllers connected to the wireless device. The carrier establishment request is used to request establishment of a first carrier for the first wireless device controller. The wireless device then determines first physical resource information based on the carrier establishment request, where the first physical resource information indicates physical resources required to establish the first carrier. The wireless device then determines whether to establish the first carrier based on the first physical resource information and physical resources corresponding to the first wireless device controller in the wireless device, where the at least two wireless device controllers correspond to different physical resources in the wireless device.

[0043] In this application, in addition to the wireless device being able to connect to at least two wireless device controllers, the wireless device can also obtain the physical resources corresponding to each wireless device controller, and the at least two wireless device controllers correspond to different physical resources in the wireless device. Therefore, after receiving the carrier establishment request, the wireless device can determine whether the resources indicated by the first physical resource information are sufficient to establish the first carrier based on the physical resources corresponding to the first wireless device controller (the wireless device controller that sent the carrier establishment request), without utilizing the physical resources corresponding to other wireless device controllers. Therefore, it is possible for the aforementioned multiple wireless device controllers to independently manage the physical resources in the wireless device. While enabling multiple wireless device controllers to share a wireless device, the flexibility of the wireless device controllers in managing the corresponding wireless devices is improved.

[0044] In a possible implementation, the wireless device stores a first resource table, where the first resource table includes physical resources corresponding to each of the at least two wireless device controllers.

[0045] Optionally, the first resource table further includes the types of physical resources that each wireless device controller is allowed to use, and the resource quantity of each physical resource or the resource attributes of each physical resource.

[0046] It should be understood that the physical resources corresponding to each wireless device controller in the aforementioned first resource table can be manually pre-allocated or dynamically allocated by the wireless device. For example, the first resource table can be manually input into a storage module of the wireless device; or the first resource table can be manually input into one of the at least two wireless device controllers connected to the aforementioned wireless device. The wireless device controller then sends the first resource table to the wireless device, which then stores the first resource table in the storage module. This application does not limit the implementation method for the wireless device to obtain the first resource table. It should be understood that regardless of which of the aforementioned implementation methods is adopted, the physical resources corresponding to different wireless device controllers are determined, and the processing module in the wireless device can only allocate the physical resources corresponding to the first wireless device controller to the first wireless device controller for use.

[0047] In conventional technology, since the primary carrier's radio device controller requests resources from the wireless device, the wireless device is unaware of which carrier's carrier the physical resources requested by the primary carrier's radio device controller are used to establish. Therefore, conventional wireless devices lack the aforementioned first resource table. This application stores a first resource table in the wireless device that records the physical resources corresponding to each radio device controller. This allows the physical resources in the wireless device to be divided among at least two radio device controllers connected to the wireless device, allowing the wireless device to use the physical resources corresponding to each radio device controller during the carrier establishment phase. This helps ensure that resource allocation in the wireless device does not conflict.

[0048] In a possible implementation, the carrier establishment request includes an identifier of the first wireless equipment controller, where the identifier of the first wireless equipment controller is used to indicate an application for physical resources corresponding to the first wireless equipment controller;

[0049] Before the wireless device determines whether to establish the first carrier according to the first physical resource information and the physical resources corresponding to the first wireless device controller in the wireless device, the method further includes:

[0050] The wireless device searches the first resource table for physical resources corresponding to the first wireless device controller according to the identifier of the first wireless device controller.

[0051] In this embodiment, it is proposed that the wireless device can query the physical resources corresponding to the first wireless device controller in the first resource table based on the identifier of the first wireless device controller, which is conducive to ensuring the accuracy of the wireless device querying the physical resources corresponding to the first wireless device controller.

[0052] In a possible implementation, the wireless device determines whether to establish the first carrier according to the first physical resource information and the physical resources corresponding to the first wireless device controller in the wireless device, including:

[0053] When the amount of the physical resources indicated by the first physical resource information is less than the amount of the physical resources corresponding to the first wireless device controller, the wireless device uses the physical resources indicated by the first physical resource information to establish the first carrier.

[0054] In one possible implementation, the method further includes:

[0055] The wireless device updates the resource amount of the physical resource corresponding to the first wireless device controller in the first resource table according to the resource amount of the physical resource indicated by the first physical resource information.

[0056] In a possible implementation manner, the carrier establishment request further includes a first carrier parameter, where the first carrier parameter is used to indicate a feature of the first carrier;

[0057] The wireless device determines first physical resource information according to the carrier establishment request, including:

[0058] The wireless device generates the first physical resource information based on the first carrier parameter and a preset rule corresponding to the first wireless device controller, where different wireless device controllers among the at least two wireless device controllers correspond to different preset rules, and the first physical resource information includes information on at least one of frequency band resources, power resources, channel resources, carrier resources, and number of stream resources.

[0059] In a possible implementation manner, after the wireless device establishes the first carrier using the physical resources indicated by the first physical resource information, the method further includes:

[0060] The wireless device receives a resource query message from the first wireless device controller, the resource query message being used to query the wireless device for usage information of a physical resource corresponding to the first wireless device, the resource query message including an identifier of the first wireless device controller;

[0061] The wireless device queries the first resource table for usage information of the physical resource corresponding to the first wireless device controller;

[0062] The wireless device sends usage information of physical resources corresponding to the first wireless device controller to the first wireless device controller.

[0063] In this embodiment, the wireless device may also query the physical resource usage information corresponding to one of the at least two wireless device controllers based on wireless device controller granularity, and provide feedback to the wireless device controller regarding the physical resource usage of the wireless device controller. This helps prevent the wireless device from misreporting the physical resource usage of a wireless device controller to other wireless device controllers, and improves the accuracy of the physical resource usage information queried by the wireless device for each wireless device controller.

[0064] In one possible implementation, the method further includes:

[0065] The wireless device obtains fault information, where the fault information is used to indicate at least one physical resource in the wireless device that has a fault;

[0066] The wireless device determines, from the at least two wireless device controllers, at least one second wireless device controller, where the second wireless device controller is a wireless device controller that uses the physical resource indicated by the fault information;

[0067] The wireless device sends the fault information to the second wireless device controller.

[0068] In this embodiment, the wireless device can also provide fault feedback based on the granularity of the radio device controller. Specifically, the wireless device can determine which radio device controllers are affected by the faulty physical resource. The wireless device then provides fault information only to the affected radio device controllers, rather than to all radio device controllers connected to the wireless device.

[0069] In a possible implementation manner, before the wireless device receives the carrier establishment request from the first wireless device controller, the method further includes:

[0070] The wireless device obtains a resource configuration message including the first resource table, parses the resource configuration message, and stores the resource configuration message in a storage module.

[0071] Exemplarily, the wireless device receives a resource configuration message from one of at least two wireless device controllers connected to the wireless device, where the resource configuration message includes the aforementioned first resource table.

[0072] It should be noted that there are many other implementations of this aspect. For details, please refer to the specific implementations and beneficial effects of the first aspect, which will not be repeated here.

[0088] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0089] The terms "first," "second," "third," "fourth," and the like (if any) in the specification and claims of this application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0090] In this application, in order to realize that multiple wireless device controllers share the physical resources in the same wireless device, the following method is proposed: Figure 1B The communication system shown may be a base station system including a wireless device and at least two wireless device controllers. Each wireless device controller can be connected to a network management device. Users can manage the wireless device controller connected to the network management device through the network management device and, in turn, request access to physical resources in the wireless device through the wireless device controller.

[0091] Among them, the wireless device controller can be a network element or device with a baseband signal processing function, or a device with a wireless signal processing function for managing the access network (radio access network, RAN). The wireless device controller can complete baseband signal processing functions such as coding, multiplexing, modulation and spread spectrum, can complete the function of processing signaling from wireless devices, can realize the function of local management and remote operation and maintenance of wireless devices, and provide clock synchronization for transmission equipment or wireless devices. Exemplarily, the wireless device controller can be a baseband processing unit (base band unit, BBU) (also known as an indoor baseband processing unit (building base band unit, BBU)) in an access network device (e.g., a base station). For example, in a long-term evolution advanced (LTE) system or an evolved LTE (long term evolution advanced, LTE-A) system, the wireless device controller can be a baseband processing unit BBU in an evolved base station (evolutional node B, eNB or e-NodeB). For another example, in a 5G NR system, the wireless device controller can be a baseband processing unit BBU in a next-generation node B (gNB). For example, in the 5th generation mobile communication technology (5G) new radio (NR) system, the wireless device controller may also be a distributed unit (DU) in a cloud radio access network (CloudRAN) or an open radio access network (ORAN) system, or a centralized unit (CU) (also referred to as a control unit), or a combination of a centralized unit CU and a distributed unit DU. In practical applications and subsequent network evolution, the wireless device controller may also be other devices or apparatuses having baseband signal processing functions, or other devices or apparatuses having wireless signal processing functions for managing access networks RAN.

[0092] In addition, the aforementioned wireless device may be a radio unit (RU) (also referred to as a radio frequency unit) in an access network RAN ​​device (e.g., a base station), or may be other processing devices having the function of processing wireless signals (e.g., intermediate frequency signals, radio frequency signals, etc.). Exemplarily, the wireless device may be a remote radio unit (RRU) (also referred to as a remote radio module) or a remote radio head (RRH) in a base station. RRU is generally used for conventional outdoor coverage of a macro station; RRH is generally used for indoor coverage of an indoor distribution system. Exemplarily, the wireless device may also be an active antenna unit (AAU), that is, a processing unit integrated with an RRU (or RRH) and an antenna. In actual applications, and in subsequent network evolution, the wireless device may also be other devices or apparatuses capable of transmitting and receiving radio frequency signals, and processing radio frequency signals or intermediate frequency signals.

[0093] Optionally, exemplarily, some of the physical layer functions in the baseband unit can be transferred to the radio frequency unit. In this case, the aforementioned wireless device can have some of the physical layer functions of the BBU, such as modulation, demodulation, layer mapping, Fourier transform (fast fourier transformation, FFT) and channel estimation / equalization functions.

[0094] Optionally, the aforementioned wireless device and the wireless device controller can be directly connected through a transmission medium (for example, a transmission medium such as an optical fiber or a cable), or can be connected through a fronthaul network (FTN) composed of one or more transmission devices. The aforementioned fronthaul network includes but is not limited to the fronthaul network of the LTE system, the fronthaul network of 5G NR, the fronthaul network of the 6th generation mobile communication technology (6G) system, and even the fronthaul network in the subsequent evolution standard. The aforementioned transmission device is a network device used to transmit data in the fronthaul network. For example, the transmission device can be a packet transport network (PTN) device, a router, a switch, a microwave device, and an optical transport network (OTN) device, etc., which can realize message processing and data transmission. In addition, the aforementioned transmission device can also be a network device that integrates the functions of one or more of the aforementioned devices, which is not limited here.

[0095] In addition, the wireless device and the wireless device controller in the communication system proposed in this application are connected via a fronthaul interface. The fronthaul interface can be an interface defined in traditional technologies for dividing the physical layer of the communication system, such as the enhanced common public radio interface (eCPRI), the common public radio interface (CPRI), the interface in the open basestation architecture initiative (OBASI), and other interfaces that can connect wireless devices and wireless device controllers.

[0096] It should also be understood that when the communication protocols used between the wireless device controller and the wireless device are different, that is, when the fronthaul interfaces used between the wireless device controller and the wireless device are different, the name of the wireless device controller may be different, and the name of the wireless device may also be different. For example, in the Common Public Radio Interface (CPRI) protocol, the wireless device controller is called a radio equipment controller (REC), and the wireless device is called a radio equipment (RE); in the enhanced Common Public Radio Interface (eCPRI) protocol, the wireless device controller is called an eCPRI radio equipment controller (eREC), and the wireless device is called an eCPRI radio equipment controller (eCPRI radio equipment control, eRE). It should be understood that in other protocols that provide communication between the baseband unit and the radio frequency unit, the wireless device controller may have other names. Specifically, this application does not limit the specific implementation form and specific name of the wireless device controller, and it will be introduced in the following text as "wireless device controller". Similarly, in other protocols that provide communication between baseband units and radio frequency units, the wireless device may have other names. Specifically, this application does not limit the specific implementation form and specific name of the wireless device, and the term "wireless device" will be used to introduce it in the following text.

[0097] The following will be combined Figure 2A This chapter introduces the internal structure of wireless devices. Figure 2AFIG. 2 is an embodiment of a wireless device 20 provided by the present application. The wireless device 20 includes an interface module 201 and a processing module 202. Optionally, the wireless device 20 also includes a storage module 203 and a carrier establishment module 204.

[0098] The interface module 201 is configured to obtain a carrier establishment request from a first wireless device controller, where the first wireless device controller is one of at least two wireless device controllers connected to the wireless device. Figure 2A In the example, wireless device 20 is connected to n wireless device controllers, such as wireless device controller 1 and wireless device controller 2, where n is an integer greater than 1. Figure 2A One of the aforementioned n wireless device controllers in the wireless device controller.

[0099] Optionally, the at least two wireless device controllers may belong to different operators. For example, wireless device controller 1 belongs to operator 1, and wireless device controller 2 belongs to operator 2, where operator 1 and operator 2 are different operators. Generally, when two wireless device controllers belong to different operators, the two wireless device controllers have different management logic and can use different physical resources in the wireless device.

[0100] Furthermore, the aforementioned carrier establishment request is used to request establishment of a first carrier for the first wireless device controller. It can also be understood that the carrier establishment request is used to request the wireless device to use a portion of physical resources, so that the wireless device uses the aforementioned physical resources to establish the first carrier for the first wireless device controller. Of course, the carrier establishment request carries some information required to establish the first carrier, which will be described in detail later.

[0101] In addition, the processing module 202 is configured to determine first physical resource information according to the carrier establishment request, and determine whether to establish a first carrier according to the first physical resource information and physical resources corresponding to the first wireless device controller in the wireless device.

[0102] The first physical resource information is determined by processing module 202 based on the content carried in the carrier establishment request. The first physical resource information is used to indicate the physical resources required to establish the first carrier. It should be understood that the first physical resource information may indicate one physical resource or multiple physical resources. Physical resources include, but are not limited to, frequency band resources, power resources, channel resources, carrier resources, and stream number resources. Therefore, the first physical resource information includes information on at least one of the following: frequency band resources, power resources, channel resources, carrier resources, and stream number resources.

[0103] Among them, frequency band resources refer to the frequency band or frequency domain range used when establishing a carrier. Generally, frequency band resources are resources related to the operator. Each operator has a fixed frequency band, and different operators are allowed to use different frequency bands. For example, the frequency band resources are the operator's licensed frequency bands, and different operators have different licensed frequency bands. The wireless device controller is only allowed to use the frequency band of the operator to which the wireless device controller belongs. For example, if 1.8GHz1890MHz~1895MHz belongs to operator 1, the wireless device controller of operator 2 cannot use the aforementioned 1.8GHz1890MHz~1895MHz frequency band resources. Only the wireless device controller of operator 1 can apply to use the aforementioned 1.8GHz1890MHz~1895MHz frequency band resources. In addition, frequency band resources include transmitting frequency and receiving frequency. Generally, in frequency-division duplex (FDD) mode, the transmitting frequency is different from the receiving frequency. For example, in 1.8 GHz, you can set 1765 MHz to 1785 MHz as the transmit frequency (also known as the uplink frequency), and set 1860 MHz to 1880 MHz as the receive frequency (also known as the downlink frequency). For another example, in 2.1 GHz, you can set 1920 MHz to 1960 MHz as the transmit frequency, and set 2110 MHz to 2150 MHz as the receive frequency. Generally, in time-division duplex (TDD) mode, the transmit frequency and the receive frequency can be the same. For example, in 3.5 GHz, you can set 3580 MHz to 3600 MHz as the transmit frequency and receive frequency band.

[0104] It should be understood that whether the aforementioned frequency band resources adopt the FDD mode or the TDD mode is related to the carrier that the wireless device controller needs to establish, and this application does not limit the duplex mode of the frequency band resources.

[0105] Furthermore, power resources refer to the multiples of the power amplified by the power amplifier for an established carrier. Generally, carriers using different frequency bands have independent power resources available. It should be understood that the aforementioned power resources are at the frequency band level, and wireless devices share power resources among all carriers within the same frequency band. For example, all 1.8 GHz carriers share 20 W of power resources; all 2.1 GHz carriers share 40 W of power resources. Therefore, if a carrier within a frequency band occupies more power resources (e.g., has higher transmit power), other carriers within that band will have less power resources available (e.g., have lower transmit power). It should be understood that the greater the transmit power of a carrier, the longer its transmission range and the wider the service range it can provide. However, greater transmit power is not necessarily better. Because the transmit power of a terminal device is fixed, if the transmit range is too far, the terminal device may only receive signals from the wireless device, but not the signals it sends. Typically, operators distribute power equally according to the spectrum bandwidth to ensure uniform coverage. For example, if the power of 2.1 GHz is 20W, and there are two carriers at 2.1 GHz with bandwidths of 20 MHz and 5 MHz respectively, then the power resources occupied by the 20 MHz carrier are 16W, and the power resources occupied by the 5 MHz carrier are 4W.

[0106] In addition, channel resources refer to the number of occupied radio frequency link channels. Generally, channel resources are related to frequency bands. For example, the channel resources of the 2.1GHz frequency band in a wireless device are 2T, and the channel resources of the 1.8GHz frequency band are 3T, which means that the wireless device can use up to two channels when establishing a carrier with a frequency band of 2.1GHz, and can use up to three channels when establishing a carrier with a frequency band of 1.8GHz. In some possible implementations, the channel resources can also indicate the identifiers or numbers of the occupied channels, that is, indicate which channels are occupied. For example, if the channel resources of the 2.1GHz frequency band in a wireless device are T1 and T2, it means that the wireless device can use two channels numbered "T1" and "T2" when establishing a carrier with a frequency band of 2.1GHz.

[0107] It should be noted that since the transmitting devices of each channel in a wireless device are independent, the power of each channel in the wireless device is also independent. If a channel is shared by multiple wireless device controllers, the channel power must also be shared by these multiple wireless device controllers. Therefore, in practical applications, channel resources and power resources are generally considered together for sharing. In one possible implementation, channel resources and power resources are combined into a single channel power resource. For example, the power allocated to channel A at 1.8 GHz is 20 W, while the power allocated to channel A at 2.1 GHz is 40 W.

[0108] In addition, carrier resources refer to the number of carriers that a wireless device can process. The carrier resources are mainly intermediate frequency digital resources, which are used to perform frequency conversion / clipping / pre-distortion and other processing on each carrier. For example, take the maximum carrier resource of a wireless device as 4 (that is, the wireless device can process up to 4 carriers). Assume that the frequency band resources corresponding to a wireless device controller are 2.1GHz 2130~2150 20M and 1.8GHz 1830~1850 20M. If the wireless device controller chooses to establish 1 2.1GHz 20M carrier and 1 1.8GHz 20M carrier, the carrier resources that the wireless device needs to consume are 2; if the wireless device controller chooses to establish 2 2.1GHz 10M carriers and 2 1.8GHz 10M carriers, the carrier resources that the wireless device needs to consume are 4. When multiple wireless device controllers share carrier resources, the more one wireless device controller uses, the less available to other wireless device controllers. This may even cause other wireless device controllers to be unable to successfully establish carriers due to a lack of carrier resources even though they have spectrum / power resources.

[0109] Furthermore, the number of flow resources refers to the number of end-user service flows that a wireless device can handle simultaneously. This includes both uplink and downlink flow resources. Uplink flow resources refer to the number of uplink service flows from end-users that a wireless device can handle simultaneously. Downlink flow resources refer to the number of downlink service flows from end-users that a wireless device can handle simultaneously.

[0110] It should be understood that stream resources are a type of baseband processing resource. Only when a wireless device has baseband processing capabilities, for example, when the wireless device controller is an AAU, can the wireless device share stream resources with multiple wireless device controllers. Generally, the more stream resources a wireless device controller receives, the more end-user data the wireless device can process for that wireless device controller, thereby providing a better communication experience for the user.

[0111] It should be understood that the aforementioned physical resources are merely examples listed for the convenience of readers' understanding. In actual applications, the wireless device may also provide other types of physical resources for the aforementioned at least two wireless device controllers. This application does not specifically limit the physical resources provided by the wireless device.

[0112] Specifically, the aforementioned first physical resource information can not only indicate the type of physical resources required to establish the first carrier, but also indicate the resource amount of each physical resource. For example, the first physical resource information can not only indicate that channel resources are required to establish the first carrier, but also clearly indicate that channel resources of two channels are required to establish the first carrier, that is, the resource amount of the channel resources is two channels. For another example, the first physical resource information can not only indicate that power resources are required to establish the first carrier, but also clearly indicate that the power resources required to establish the first carrier are 20W, that is, the transmission power of the first carrier is 20W. For another example, when the channel resources and power resources are combined into channel power resources, the first physical resource information can indicate that the channel power resources required to establish the first carrier are A channel 20W, that is, the first carrier uses A channel, and the transmission power of the first carrier is 20W.

[0113] It should be understood that the aforementioned first physical resource information can not only indicate the type of physical resources required to establish the first carrier, and the resource amount of each physical resource, but also indicate the attributes of each physical resource. For example, the first physical resource information can indicate that the physical resources required to establish the first carrier are of the type of frequency band resources, the resource amount of the frequency band resources is 5MHz, and the attributes of the frequency band resources are 1.8GHz 1890MHz~1895MHz. For another example, the first physical resource information can indicate that the physical resources required to establish the first carrier are of the type of channel resources, the resource amount of the frequency band resources is 2 channels, and the attributes of the frequency band resources are a radio frequency channel with a channel number of T1 and a radio frequency channel with a channel number of T2.

[0114] It should be understood that different radio device controllers can use different physical resources within the wireless device. Specifically, the physical resources within the wireless device 20 are divided among the at least two radio device controllers, and the at least two radio device controllers correspond to different physical resources within the wireless device 20. In other words, information such as which radio device controllers the physical resources within the wireless device 20 are divided to and which physical resources each radio device controller is permitted to use is determined. Therefore, when the processing module 202 learns, based on the first physical resource information, which physical resources the first radio device controller needs to use when applying to establish a first carrier, the processing module 202 needs to determine the relationship between the physical resources indicated by the first physical resource information and the physical resources corresponding to the first radio device controller in the wireless device to determine whether to establish the first carrier.

[0115] Specifically, the processing module 202 needs to determine whether the physical resource indicated by the first physical resource information belongs to the physical resource corresponding to the first wireless device controller. If the physical resource indicated by the first physical resource information belongs to the physical resource corresponding to the first wireless device controller, the processing module 202 determines that the first carrier is allowed to be established; if the physical resource indicated by the first physical resource information does not belong to the physical resource corresponding to the first wireless device controller, the processing module 202 determines that the first carrier is not allowed to be established.

[0116] It can also be understood that the processing module 202 determines whether to allow the establishment of the first carrier based on the relationship between the resource amount of the physical resources indicated by the first physical resource information and the resource amount of the physical resources corresponding to the first wireless device controller. For example, if the resource amount of the physical resources indicated by the first physical resource information is less than the resource amount of the physical resources corresponding to the first wireless device controller, the processing module 202 determines to allow the establishment of the first carrier. The processing module 202 then transmits the first physical resource information to the carrier establishment module 204, which uses the physical resources indicated by the first physical resource information to establish the first carrier. If the resource amount of the physical resources indicated by the first physical resource information is greater than the resource amount of the physical resources corresponding to the first wireless device controller, the processing module 202 determines not to allow the establishment of the first carrier and controls the interface module 201 to send a carrier establishment response to the first wireless device controller, where the carrier establishment response indicates that the establishment of the first carrier has failed.

[0117] In this embodiment, the wireless device 20 can connect to multiple wireless device controllers and receive a carrier establishment request from one of the multiple wireless device controllers. Based on the carrier establishment request, the wireless device 20 determines the physical resources for establishing a carrier, and then determines whether to establish a carrier based on the physical resources and the physical resources corresponding to the wireless device controller in the wireless device. This allows multiple wireless device controllers to share a single wireless device, increasing the flexibility of wireless device controllers in managing wireless devices.

[0118] The wireless device 20 further includes a storage module 203. The storage module 203 may be coupled to the processing module 202 or may be independent of the processing module 202. The storage module 203 is configured to store a first resource table, which includes physical resources corresponding to each of the at least two wireless device controllers connected to the wireless device 20.

[0119] Optionally, the first resource table further includes the types of physical resources that each wireless device controller is allowed to use, and the resource quantity of each physical resource or the resource attributes of each physical resource.

[0120] For ease of understanding, let's take the example of wireless device 20 being connected to wireless device controller 1 and wireless device controller 2. In this case, the first resource table stored in storage module 203 of wireless device 20 includes physical resources corresponding to wireless device controller 1 and physical resources corresponding to wireless device controller 2. The physical resources corresponding to wireless device controller 1 include multiple physical resources, such as frequency band resources, power resources, channel resources, and carrier resources. The physical resources corresponding to wireless device controller 2 also include multiple physical resources, such as frequency band resources, power resources, channel resources, and carrier resources. In this case, the first resource table in wireless device 20 may be as shown in Table 1-1 below:

[0121] Table 1-1

[0122]

[0123] In the example shown in Table 1-1, wireless device 20 divides physical resources between wireless device controller 1 and wireless device controller 2. The physical resources corresponding to wireless device controller 1 and wireless device controller 2 are different. Based on the carrier resources in Table 1-1, the wireless device allows wireless device controller 1 to establish a maximum of four carriers, and wireless device controller 2 to establish a maximum of two carriers. For wireless device controller 1, the wireless device can process a maximum of six uplink traffic flows and eight downlink traffic flows, and a maximum of two uplink traffic flows and eight downlink traffic flows, respectively.

[0124] For example, wireless device controller 1 allows the use of frequency band resources in four frequency bands: the transmit frequency band of "1.8 GHz 1765 MHz to 1785 MHz", the receive frequency band of "1.8 GHz 1860 MHz to 1880 MHz", the transmit frequency band of "2.1 GHz 1920 MHz to 1960 MHz", and the receive frequency band of "2.1 GHz 2110 MHz to 2150 MHz". Wireless device controller 2 allows the use of frequency band resources in two frequency bands: the transmit frequency band of "1.8 GHz 1745 MHz to 1765 MHz" and the receive frequency band of "1.8 GHz 1840 MHz to 1860 MHz".

[0125] For another example, if the wireless device controller 1 uses a 2.1 GHz frequency band to generate a carrier, the wireless device 20 allows the wireless device controller 1 to use a function of 40W; if the wireless device controller 1 uses a 1.8 GHz frequency band to generate a carrier, the wireless device 20 allows the wireless device controller 1 to use a function of 20W.

[0126] For another example, if the wireless device controller 1 uses a 2.1 GHz frequency band to generate a carrier, the wireless device 20 allows the wireless device controller 1 to use channel resources of two channels, namely, channel 1 (i.e., the channel identified as "T1" in Table 1-1) and channel 2 (i.e., the channel identified as "T2" in Table 1-1); if the wireless device controller 1 uses a 1.8 GHz frequency band to generate a carrier, the wireless device 20 allows the wireless device controller 1 to use channel resources of the other two channels, namely, channel 5 (i.e., the channel identified as "T5" in Table 1-1) and channel 6 (i.e., the channel identified as "T6" in Table 1-1).

[0127] In another possible example, if power resources and channel resources are combined, the physical resources corresponding to wireless device controller 1 include multiple physical resources such as frequency band resources, channel power resources, and carrier resources, and the physical resources corresponding to wireless device controller 2 also include multiple physical resources such as frequency band resources, channel power resources, and carrier resources. In this case, the first resource table in the wireless device 20 can be as shown in Table 1-2 below:

[0128] Table 1-2

[0129]

[0130] In the example shown in Table 1-2, wireless device 20 allocates physical resources to wireless device controller 1 and wireless device controller 2, where the physical resources corresponding to wireless device controller 1 and wireless device controller 2 are different. For example, if wireless device controller 1 generates a carrier using the 2.1 GHz frequency band, wireless device 20 allows wireless device controller 1 to use two channels, channel A and channel B, where the maximum power of each channel is 40 W. If wireless device controller 1 generates a carrier using the 1.8 GHz frequency band, wireless device 20 allows wireless device controller 1 to use two channels, channel A and channel B, where the maximum power of each channel is 20 W. For explanations of the other physical resources in Table 1-2, please refer to the corresponding descriptions in Table 1-1 above and are not repeated here.

[0131] It should be understood that the examples shown in Table 1-1 and Table 1-2 are only two possible examples of the first resource table proposed in this application in FDD mode. In actual applications, the frequency band resources in the first resource table can also adopt TDD mode. Therefore, there may be other examples about the first resource table, and this application will not give examples one by one.

[0132] It should be understood that the physical resources corresponding to each wireless device controller in the aforementioned first resource table can be manually pre-allocated or dynamically allocated by the wireless device 20. For example, the first resource table can be manually input into the storage module 203 of the wireless device 20; or the first resource table can be manually input into one of the at least two wireless device controllers connected to the wireless device 20. The wireless device controller then sends the first resource table to the wireless device 20, which then stores the first resource table in the storage module 203. This application does not limit the implementation method by which the wireless device 20 obtains the first resource table. It should be understood that regardless of which implementation method is adopted, the physical resources corresponding to different wireless device controllers are determined, and the processing module 202 in the wireless device 20 can only allocate the physical resources corresponding to the first wireless device controller to the first wireless device controller for use.

[0133] In conventional technology, since it is the primary carrier's radio device controller that requests resources from the wireless device, the wireless device is unaware of which carrier's carrier the physical resources requested by the primary carrier's radio device controller are used to establish. Therefore, conventional wireless devices lack the aforementioned first resource table. This application stores a first resource table in wireless device 20 that records the physical resources corresponding to each radio device controller. This allows the physical resources in wireless device 20 to be divided among at least two radio device controllers connected to wireless device 20, allowing wireless device 20 to use the physical resources corresponding to each radio device controller during the carrier establishment phase. This helps ensure that resource allocation in wireless device 20 does not conflict.

[0134] In one possible implementation, the carrier establishment request includes an identifier of the first wireless device controller, where the identifier of the first wireless device controller indicates a request for physical resources corresponding to the first wireless device controller. Since the processing module 202 is able to obtain the storage location of the first resource table, the processing module 202 is further configured to query the first resource table for the physical resources corresponding to the first wireless device controller based on the identifier of the first wireless device controller.

[0135] Optionally, if the information of physical resources corresponding to different wireless device controllers in the first resource table is stored in different storage locations, the processing module 202 can only query the storage page of the physical resources corresponding to the first wireless device controller based on the identifier of the first wireless device controller, without traversing the storage location of the entire first resource table.

[0136] Optionally, the processing module 202 may further perform a validity check on the corresponding carrier establishment request based on the identifier of the first wireless device controller. For example, the processing module 202 may determine, based on the identifier of the first wireless device controller, whether the carrier establishment request originates from the wireless device controller indicated by the identifier of the first wireless device controller. This helps prevent other wireless device controllers from maliciously forging the carrier establishment request of the first wireless device controller, thereby affecting the carrier establishment of the first wireless device controller.

[0137] In this embodiment, since the wireless device in the conventional technology does not have the first resource table, the wireless device in the conventional technology cannot query the physical resources corresponding to a wireless device controller based on the identifier of the wireless device controller.

[0138] The main structure of the wireless device 20 is introduced above. Figure 2B The various functional modules within the wireless device 20 are further introduced. Figure 2B FIG. 2 is another embodiment of a wireless device 20 provided by the present application. The wireless device 20 includes an interface module 201 , a processing module 202 , a storage module 203 and a carrier establishment module 204 .

[0139] The processing module 202 includes a central control module 2021 and at least two service processing modules 2022. The at least two wireless device controllers correspond to the at least two service processing modules 2022 on a one-to-one basis. Each service processing module 2022 only processes messages (e.g., carrier establishment requests) from the corresponding wireless device controller. For example, Figure 2B The central control module 2021 is connected to n service processing modules 2022, such as service processing module 1 and service processing module 2, where n is an integer greater than 1. If wireless device controller 1 corresponds to service processing module 1, service processing module 1 can only process messages from wireless device controller 1; if wireless device controller 2 corresponds to service processing module 2, service processing module 2 can only process messages from wireless device controller 2. This process is analogous and not further described here.

[0140] It should be understood that the aforementioned first wireless device controller corresponds to the first service processing module, and the first service processing module is not Figure 2B If the identifier of the first wireless device controller indicates wireless device controller 1, the first service processing module is Figure 2B The business processing module 1 in . And so on, it is not repeated here.

[0141] Specifically, the central control module 2021 in the processing module 202 is configured to determine, based on the identifier of the first wireless device controller in the carrier establishment request, a first service processing module corresponding to the first wireless device controller from the at least two service processing modules 2022, and transmit the carrier establishment request to the first service processing module. The first service processing module is configured to determine the first physical resource information based on the carrier establishment request and transmit the first physical resource information to the central control module 2021; the central control module 2021 is configured to determine whether to establish the first carrier based on the first physical resource information and the physical resources corresponding to the first wireless device controller.

[0142] The service processing module is used to process services related to the corresponding wireless device controller. Taking the first service processing module as an example, the first service processing module corresponding to the first wireless device controller is used to determine the first physical resource information based on the carrier establishment request from the first wireless device controller. When determining the first physical resource information, the first service processing module can have the following two implementation methods:

[0143] In one implementation, the carrier establishment request directly carries the first physical resource information, and the first service processing module directly obtains the first physical resource information from the carrier establishment request.

[0144] In another implementation, the carrier establishment request carries a first carrier parameter, where the first carrier parameter is used to indicate a characteristic of the first carrier. In this case, the first service processing module is specifically configured to generate the first physical resource information based on the first carrier parameter and a preset rule corresponding to the first wireless device controller, where different wireless device controllers among the at least two wireless device controllers correspond to different preset rules, and the first physical resource information includes information on at least one of frequency band resources, power resources, channel resources, carrier resources, and number of stream resources.

[0145] Among them, the preset rules can be understood as the processing logic of the service processing module, and different service processing modules correspond to different wireless device controllers. If different service processing modules have different service processing logic, then different service processing modules correspond to different preset rules. In this embodiment, the preset rules can be understood as the rules for converting the first carrier parameters into the first wireless resource information. If the first carrier parameters are input into the service processing module corresponding to another wireless device controller (for example, the second service processing module corresponding to the second wireless device controller), the second service processing module may not be able to recognize the aforementioned first carrier parameters, and may also be unable to convert the aforementioned first carrier parameters into the first physical resource information.

[0146] For example, if operator 1 configures a 20 MHz bandwidth FDD LTE 2T2R carrier on the first wireless device controller through a network management device, using a transmit frequency of 2110 MHz to 2130 MHz and a receive frequency of 1920 MHz to 1940 MHz, the first carrier parameters in the carrier establishment request are: "Bandwidth = 20 MHz, Duplex Mode = FDD, Standard = LTE, Transmit Mode = 2T, Receive Mode = 2R, Frequency Band = 2.1 GHz." Then, based on the first carrier parameters and the preset rules corresponding to the first service processing module, the first service processing module determines the physical resource information required to establish the first carrier (i.e., first physical resource information), including: frequency band resources of "2.1 GHz receive frequency 1920 MHz to 1940 MHz, transmit frequency 2110 MHz to 2130 MHz," power resources of "2.1 GHz 20 W / channel," channel resources of "2.1 GHz 2T," uplink flow number resources of "4 flows," and downlink flow number resources of "4 flows."

[0147] The central control module 2021 may determine whether to establish the first carrier in the following two ways:

[0148] In one implementation, when the amount of physical resources indicated by the first physical resource information is less than the amount of physical resources corresponding to the first wireless device controller, the central control module 2022 determines that the first carrier is allowed to be established and transmits the first physical resource information to the carrier establishment module 204. The carrier establishment module 204 is then configured to establish the first carrier using the physical resources indicated by the first physical resource information. The carrier establishment module 204 includes a digital processing module 2041 and an analog processing module 2042. The digital processing module 2041 includes circuits or devices with digital signal processing capabilities, such as an upconverter, a downconverter, and a digital-to-analog converter. The analog processing module 2042 includes circuits or devices with analog signal processing capabilities, such as an intermediate frequency amplifier, a filter, a mixer, and a power amplifier.

[0149] Optionally, after the central control module 2022 determines that establishment of the first carrier based on the first physical resource information is permitted, the central control module 2022 updates the amount of physical resources corresponding to the first wireless device controller in the first resource table according to the amount of physical resources indicated by the first physical resource information. Exemplarily, the central control module 2022 subtracts the amount of physical resources indicated by the first physical resource information from the amount of physical resources corresponding to the first wireless device controller in the first resource table to obtain an updated amount of physical resources corresponding to the first wireless device controller. For example, the physical resources indicated by the first physical resource information include: a frequency band resource of "2.1 GHz 1920MHz-1940MHz / 2110MHz-2130MHz" and a channel power resource of "2.1 GHz 20W". The physical resources corresponding to the first wireless device controller originally recorded in the first resource table include: a frequency band resource of "2.1 GHz 1920MHz-1960MHz / 2110MHz-2150MHz" and a channel power resource of "2.1 GHz 40W", and a carrier resource of "4". After the update, the physical resources corresponding to the first wireless device controller recorded in the first resource table include: a frequency band resource of "2.1 GHz 1940MHz-1960MHz / 2130MHz-2150MHz" and a channel power resource of "2.1 GHz 20W", and a carrier resource of "3". Optionally, the central control module 2022 further stores the first physical resource information in the storage module 203 to record the physical resources used to establish the first carrier. For example, the carrier establishment module 204 determines which physical resources are used to establish the first carrier and how much each physical resource is used.

[0150] In another implementation, when the amount of physical resources indicated by the first physical resource information is greater than the amount of physical resources corresponding to the first wireless device controller, the central control module 2022 sends a first notification message to the first service processing module, where the first notification message is used to indicate that the physical resources corresponding to the first wireless device controller are insufficient to establish the first carrier. The first service processing module controls the interface module 201 to send a carrier establishment response to the first wireless device controller, where the carrier establishment response is used to indicate that establishment of the first carrier has failed.

[0151] In this embodiment, the processing module 202 is divided into two major modules: a control module (i.e., a central control module 2021) and a service module (i.e., at least two service processing modules 2022). Because each of the at least two service processing modules is independent of one another and corresponds to a wireless device controller (RDC), each service processing module can independently process messages (e.g., carrier establishment requests) for its corresponding RDC. Compared to a solution where only one service processing module processes messages from different RDCs, this not only improves service processing efficiency but also facilitates diversified service processing within a wireless device and independent updating and maintenance of each service processing module. Furthermore, when multiple RDCs connected to the wireless device 20 belong to different carriers, the wireless device 20 can run service processing modules (also understood as service processing software) for different carriers, facilitating the generation of different carriers that meet the needs of each carrier within the wireless device based on the different service processing modules.

[0152] Furthermore, in an optional embodiment, the interface module 201 is further configured to obtain a resource configuration message, the resource configuration message including the first resource table. In this embodiment, since the wireless device and the wireless device controller are not necessarily located in the same geographical location (for example, the wireless device is often located on a signal tower, and the device controller does not need to be located in the base station's computer room), the first resource table is sent to the wireless device 20 via a wireless device controller connected to the wireless device 20. This improves resource allocation efficiency, avoids manual configuration on the signal tower, and reduces the complexity of operation and maintenance management.

[0153] In addition, in an optional embodiment, the interface module 201 is further configured to receive a resource query message from the first wireless device controller, the resource query message being used to query the usage information of the physical resources corresponding to the first wireless device controller. The resource query message includes an identifier of the first wireless device controller. Based on the identifier of the first wireless device controller in the query message, the wireless device 20 can determine that the query is for the resource usage of the first wireless device controller, rather than for the usage information of the physical resources of other wireless device controllers. Accordingly, the wireless device 20 only feeds back the usage information of the physical resources of the first wireless device controller to the first wireless device controller.

[0154] Specifically, the central control module 2021 transmits the resource query message to the first service processing module corresponding to the first wireless device controller based on the identifier of the first wireless device controller. The first service processing module queries the usage information of the physical resources corresponding to the first wireless device controller. The interface module 201 sends the usage information of the physical resources corresponding to the first wireless device controller to the first wireless device controller.

[0155] In this embodiment, each service processing module can query the physical resource usage information of a wireless device controller and provide feedback to the wireless device controller. This helps prevent the wireless device 20 from misreporting the physical resource usage of the wireless device controller to the wireless device controller.

[0156] In an optional embodiment, the central control module 2021 is further configured to obtain fault information, where the fault information indicates a physical resource in the wireless device 20 that has failed. The central control module 2021 then determines at least one second wireless device controller from the at least two wireless device controllers, where the second wireless device controller uses the physical resource indicated by the fault information. The central control module 2021 then controls the interface module 201 to send the fault information to the second wireless device controller.

[0157] In this embodiment, central control module 2021 in wireless device 20 is capable of detecting physical resource failures and, based on the physical resource failure, determining the scope of the failure, specifically which wireless device controllers (referred to in this embodiment as the second wireless device controller) are affected by the failed physical resource. Central control module 2021 then controls interface module 201 to send fault information only to the second wireless device controller, without sending fault information to other wireless device controllers. This embodiment facilitates accurate fault reporting from wireless device 20 to the wireless device controller, preventing wireless device 20 from reporting faults to all wireless device controllers connected to it.

[0158] In addition, if Figure 3 As shown, the present application also provides a communication device 30. Figure 2A or Figure 2B The wireless device 20 in the corresponding embodiment can be based on the Figure 3The structure of the communication device 30 shown. It should be understood that the aforementioned communication device 30 can be a radio unit (RU) (also known as a radio frequency unit) in an access network RAN ​​device (e.g., a base station), or it can be other processing devices with the function of processing wireless signals (e.g., intermediate frequency signals, radio frequency signals, etc.). Exemplarily, the communication device 30 can be a remote radio unit (RRU) (also known as a remote radio module) or a remote radio head (RRH) in a base station. Among them, RRU is generally used for conventional outdoor coverage of macro stations; RRH is generally used for indoor coverage of indoor distribution systems. Exemplarily, the communication device 30 can also be an active antenna unit (AAU), that is, a processing unit integrated with an RRU (or RRH) and an antenna. In actual applications, and in subsequent network evolution, the wireless device can also be other devices or apparatuses with the function of transmitting and receiving radio frequency signals, and processing radio frequency signals or intermediate frequency signals.

[0159] The communication device 30 includes at least one processor 301, at least one memory 302, at least one transceiver 303, and one or more antennas 304. The processor 301, memory 302, and transceiver 303 are connected via a connection device, and the antenna 304 is connected to the transceiver 303. The connection device may include various interfaces, transmission lines, or buses, etc., and this embodiment does not limit this.

[0160] Memory 302 is primarily used to store software programs and data. For example, the first resource table described above includes physical resources corresponding to each of the at least two wireless device controllers. Optionally, the first resource table also includes the types of physical resources permitted for use by each wireless device controller, as well as the resource quantity or resource attributes of each physical resource.

[0161] It should be understood that the memory 302 can be independent and connected to the processor 301. Optionally, the memory 302 can be integrated with the processor 301, for example, integrated into one or more chips. The memory 302 can store program codes for executing the technical solutions of the embodiments of the present application, and the execution is controlled by the processor 301. The various computer program codes executed can also be regarded as drivers for the processor 301. It should be understood that the memory 302 in this embodiment can be integrated with the processor 301, for example, integrated into one or more chips. Figure 3Only one memory and one processor are shown, but in actual applications, the communication device 30 may have multiple processors or multiple memories, which is not limited here. In addition, the memory 302 may also be referred to as a storage medium or storage device. The memory 302 may be a storage element on the same chip as the processor (i.e., an on-chip storage element) or an independent storage element, which is not limited in the embodiments of the present application.

[0162] In this embodiment, the transceiver 303 can be used to support the reception or transmission of radio frequency signals between the communication device 30 and the terminal device, and the transceiver 303 can be connected to the antenna 304. The transceiver 303 includes a transmitter Tx and a receiver Rx. Specifically, one or more antennas 304 can receive radio frequency signals. The receiver Rx of the transceiver 303 is used to receive the radio frequency signal from the antenna 304 and convert the radio frequency signal into a digital baseband signal or a digital intermediate frequency signal, so that the aforementioned digital baseband signal or digital intermediate frequency signal is transmitted to the wireless device controller, so that the wireless device controller can further process the digital baseband signal or digital intermediate frequency signal, such as demodulation and decoding. In addition, the transmitter Tx in the transceiver 303 is also used to receive a modulated digital baseband signal or digital intermediate frequency signal from the wireless device controller, convert the modulated digital baseband signal or digital intermediate frequency signal into a radio frequency signal, and transmit the radio frequency signal through one or more antennas 304. Specifically, the receiver Rx can selectively perform one or more stages of down-mixing and analog-to-digital conversion on the RF signal to obtain a digital baseband signal or a digital intermediate frequency signal. The order of the down-mixing and analog-to-digital conversion processes is adjustable. The transmitter Tx can selectively perform one or more stages of up-mixing and digital-to-analog conversion on the modulated digital baseband signal or digital intermediate frequency signal to obtain a RF signal. The order of the up-mixing and digital-to-analog conversion processes is adjustable. The digital baseband signal and the digital intermediate frequency signal may be collectively referred to as digital signals.

[0163] It should be understood that the aforementioned transceiver 303 may also be referred to as a transceiver unit, a transceiver, a transceiver device, etc. Optionally, a device in the transceiver unit that implements a receiving function may be referred to as a receiving unit, and a device in the transceiver unit that implements a transmitting function may be referred to as a transmitting unit. That is, the transceiver unit includes a receiving unit and a transmitting unit. The receiving unit may also be referred to as a receiver, an input port, a receiving circuit, etc., and the transmitting unit may be referred to as a transmitter, a transmitter, or a transmitting circuit, etc.

[0164] In addition, the aforementioned processor 301 is mainly used to process the communication protocol and communication data, execute the software program, and process the data of the software program, for example, to support the communication device 30 to perform the actions described in the aforementioned embodiment. In a possible implementation, the communication device 30 is used to perform the following Figure 6 The method in the corresponding embodiment.

[0165] Specifically, when the processor 301 of the communication device 30 is used to obtain a carrier establishment request from a first wireless device controller, the first wireless device controller is one of at least two wireless device controllers connected to the wireless device, and the carrier establishment request is used to request the establishment of a first carrier of the first wireless device controller; the processor 301 is also used to determine first physical resource information based on the carrier establishment request, and the first physical resource information is used to indicate the physical resources required to establish the first carrier; the processor 301 is also used to determine whether to establish the first carrier based on the first physical resource information and the physical resources corresponding to the first wireless device controller in the wireless device, and the at least two wireless device controllers correspond to different physical resources in the wireless device.

[0166] In this embodiment, the communication device 30 is not only capable of connecting to at least two wireless device controllers, but is also capable of obtaining information about the physical resources corresponding to each wireless device controller. Furthermore, the at least two wireless device controllers correspond to different physical resources within the wireless device. Therefore, after receiving the carrier establishment request, the communication device 30 can determine whether the resources indicated by the first physical resource information are sufficient to establish the first carrier based on the physical resources corresponding to the first wireless device controller (the wireless device controller that sent the carrier establishment request), without utilizing the physical resources corresponding to other wireless device controllers. Consequently, the aforementioned multiple wireless device controllers can independently manage the physical resources within the communication device 30. While enabling multiple wireless device controllers to share a single communication device 30, the flexibility of the wireless device controllers in managing the communication device 30 is enhanced.

[0167] In one possible implementation, the communication device 30 stores a first resource table, where the first resource table includes physical resources corresponding to each of the at least two wireless device controllers. Optionally, the first resource table also includes the types of physical resources allowed to be used by each wireless device controller, as well as the resource quantity or resource attributes of each physical resource.

[0168] In addition, the carrier establishment request received by the communication device 30 includes an identifier of the first wireless device controller, which indicates a request for physical resources corresponding to the first wireless device controller. The physical resources corresponding to the first wireless device controller include various physical resources such as frequency band resources, power resources, channel resources, and carrier resources.

[0169] The processor 301 is specifically configured to query the first resource table for physical resources corresponding to the first wireless device controller according to the identifier of the first wireless device controller.

[0170] In conventional technology, since the primary carrier's radio device controller requests resources from the wireless device, the wireless device is unaware of which carrier's carrier the physical resources requested by the primary carrier's radio device controller are used to establish. Therefore, conventional wireless devices lack the aforementioned first resource table. This application stores a first resource table in the wireless device that records the physical resources corresponding to each radio device controller. This allows the physical resources in the wireless device to be divided among at least two radio device controllers connected to the wireless device, allowing the wireless device to use the physical resources corresponding to each radio device controller during the carrier establishment phase. This helps ensure that resource allocation in the wireless device does not conflict.

[0171] In a possible implementation, the processor 301 is specifically configured to establish the first carrier using the physical resources indicated by the first physical resource information when the amount of physical resources indicated by the first physical resource information is less than the amount of physical resources corresponding to the first wireless device controller.

[0172] In a possible implementation, the processor 301 is further configured to enable the wireless device to update the amount of the physical resource corresponding to the first wireless device controller in the first resource table according to the amount of the physical resource indicated by the first physical resource information.

[0173] In one possible implementation, the carrier establishment request further includes a first carrier parameter, where the first carrier parameter is used to indicate a characteristic of the first carrier. The processor 301 is specifically configured to generate the first physical resource information based on the first carrier parameter and a preset rule corresponding to the first wireless device controller, where different wireless device controllers among the at least two wireless device controllers correspond to different preset rules, and the first physical resource information includes information on at least one of frequency band resources, power resources, channel resources, carrier resources, and number of stream resources.

[0174] For details, please refer to the previous article Figure 2A and Figure 2B The various functions of the wireless device 20 are not described in detail here.

[0175] In addition, if Figure 4 As shown, the present application also provides a communication device 40. The communication device 40 is a chip for implementing the aforementioned Figure 2A or Figure 2B It should be understood that in this embodiment, the communication device 40 and the aforementioned carrier establishment module 204, antenna and other structures can constitute the aforementioned wireless device 20.

[0176] The communication device 40 includes an interface module 401 , a processing module 402 and a storage module 403 .

[0177] The interface module 401 is configured to obtain a carrier establishment request from a first wireless device controller, where the first wireless device controller is one of at least two wireless device controllers connected to the wireless device, and the carrier establishment request is configured to request establishment of a first carrier of the first wireless device controller.

[0178] The processing module 402 is configured to determine first physical resource information based on the carrier establishment request, and determine whether to establish the first carrier based on the first physical resource information and physical resources corresponding to the first wireless device controller in the wireless device. The first physical resource information indicates physical resources required to establish the first carrier, and the at least two wireless device controllers correspond to different physical resources in the wireless device.

[0179] The storage module 403 is configured to store a first resource table, where the first resource table includes physical resources corresponding to each of the at least two wireless device controllers.

[0180] Optionally, the carrier establishment request includes an identifier of the first wireless device controller, where the identifier of the first wireless device controller is used to indicate an application for physical resources corresponding to the first wireless device controller. The processing module 402 is further configured to query the first resource table for the physical resources corresponding to the first wireless device controller based on the identifier of the first wireless device controller.

[0181] Specifically, the interface module 401, the processing module 402 and the storage module 403 in this embodiment are the same as those in the previous embodiment. Figure 2A The interface module 201, processing module 202 and storage module 203 are similar. Please refer to the relevant introduction in the previous text for details, which will not be repeated here.

[0182] In addition, if Figure 5 As shown, the present application also provides a wireless device controller 50, and the first wireless device controller described above can refer to Figure 5The structure shown. The wireless device controller 50 includes a processing module 501 and an interface module 502. The processing module 501 is configured to generate a carrier establishment request. The carrier establishment request is used to request establishment of a first carrier for a first wireless device controller; the first wireless device controller is any one of at least two wireless device controllers connected to the wireless device; the carrier establishment request includes an identifier of the first wireless device controller, the identifier of the first wireless device controller being used to indicate a request for physical resources corresponding to the first wireless device controller in the wireless device; the at least two wireless device controllers correspond to different physical resources in the wireless device. Furthermore, the interface module 502 is configured to send the carrier establishment request to the wireless device.

[0183] In this embodiment, any of the multiple wireless device controllers connected to the wireless device can send a carrier establishment request to the wireless device, requesting the establishment of a first carrier using the physical resources corresponding to the first wireless device controller in the wireless device. This enables the multiple wireless device controllers to independently manage the physical resources in the wireless device. This allows multiple wireless device controllers to share a single wireless device, while also increasing the flexibility of the wireless device controllers in managing the wireless device.

[0184] The following will be combined Figure 6 The main process of the resource management method proposed in this application is introduced. Among them, the wireless device controller and the wireless device will perform the following steps:

[0185] Step 601: A first wireless device controller sends a carrier establishment request to a wireless device; correspondingly, the wireless device obtains the carrier establishment request from the first wireless device controller.

[0186] The first wireless device controller is one of the at least two wireless device controllers connected to the wireless device. Figure 2A or Figure 2B The corresponding related introduction will not be repeated here.

[0187] In addition, the aforementioned carrier establishment request is used to request the establishment of the first carrier of the first wireless device controller. It can also be understood that the carrier establishment request is used to apply to the wireless device for the use of a portion of physical resources so that the wireless device uses the aforementioned physical resources to establish the first carrier for the aforementioned first wireless device controller.

[0188] Among them, physical resources include but are not limited to frequency band resources, power resources, channel resources, carrier resources and stream number resources.

[0189] The following is an introduction to various physical resources:

[0190] The first physical resource information is determined based on the content carried in the carrier establishment request and is used to indicate the physical resources required to establish the first carrier. It should be understood that the first physical resource information may indicate one physical resource or multiple physical resources. Physical resources include, but are not limited to, frequency band resources, power resources, channel resources, carrier resources, and stream number resources. Therefore, the first physical resource information includes information on at least one of the following: frequency band resources, power resources, channel resources, carrier resources, and stream number resources.

[0191] Among them, frequency band resources refer to the frequency band or frequency domain range used when establishing a carrier. Generally, frequency band resources are resources related to the operator. Each operator has a fixed frequency band, and different operators are allowed to use different frequency bands. For example, the frequency band resources are the operator's licensed frequency bands, and different operators have different licensed frequency bands. The wireless device controller is only allowed to use the frequency band of the operator to which the wireless device controller belongs. For example, if 1.8GHz1890MHz~1895MHz belongs to operator 1, the wireless device controller of operator 2 cannot use the aforementioned 1.8GHz1890MHz~1895MHz frequency band resources. Only the wireless device controller of operator 1 can apply to use the aforementioned 1.8GHz1890MHz~1895MHz frequency band resources. In addition, frequency band resources include transmitting frequency and receiving frequency. Generally, in frequency-division duplex (FDD) mode, the transmitting frequency is different from the receiving frequency. For example, in 1.8 GHz, you can set 1765 MHz to 1785 MHz as the transmit frequency (also known as the uplink frequency), and set 1860 MHz to 1880 MHz as the receive frequency (also known as the downlink frequency). For another example, in 2.1 GHz, you can set 1920 MHz to 1960 MHz as the transmit frequency, and set 2110 MHz to 2150 MHz as the receive frequency. Generally, in time-division duplex (TDD) mode, the transmit frequency and the receive frequency can be the same. For example, in 3.5 GHz, you can set 3580 MHz to 3600 MHz as the transmit frequency and receive frequency band.

[0192] It should be understood that whether the aforementioned frequency band resources adopt the FDD mode or the TDD mode is related to the carrier that the wireless device controller needs to establish, and this application does not limit the duplex mode of the frequency band resources.

[0193] Furthermore, power resources refer to the multiples of the power amplified by the power amplifier for an established carrier. Generally, carriers using different frequency bands have independent power resources available. It should be understood that the aforementioned power resources are at the frequency band level, and wireless devices share power resources among all carriers within the same frequency band. For example, all 1.8 GHz carriers share 20 W of power resources; all 2.1 GHz carriers share 40 W of power resources. Therefore, if a carrier within a frequency band occupies more power resources (e.g., has higher transmit power), other carriers within that band will have less power resources available (e.g., have lower transmit power). It should be understood that the greater the transmit power of a carrier, the longer its transmission range and the wider the service range it can provide. However, greater transmit power is not necessarily better. Because the transmit power of a terminal device is fixed, if the transmit range is too far, the terminal device may only receive signals from the wireless device, but not the signals it sends. Typically, operators distribute power equally according to the spectrum bandwidth to ensure uniform coverage. For example, if the power of 2.1 GHz is 20W, and there are two carriers at 2.1 GHz with bandwidths of 20 MHz and 5 MHz respectively, then the power resources occupied by the 20 MHz carrier are 16W, and the power resources occupied by the 5 MHz carrier are 4W.

[0194] In addition, channel resources refer to the number of occupied radio frequency link channels. Generally, channel resources are related to frequency bands. For example, the channel resources of the 2.1GHz frequency band in a wireless device are 2T, and the channel resources of the 1.8GHz frequency band are 3T, which means that the wireless device can use up to two channels when establishing a carrier with a frequency band of 2.1GHz, and can use up to three channels when establishing a carrier with a frequency band of 1.8GHz. In some possible implementations, the channel resources can also indicate the identifiers or numbers of the occupied channels, that is, indicate which channels are occupied. For example, if the channel resources of the 2.1GHz frequency band in a wireless device are T1 and T2, it means that the wireless device can use two channels numbered "T1" and "T2" when establishing a carrier with a frequency band of 2.1GHz.

[0195] It should be noted that since the transmitting devices of each channel in a wireless device are independent, the power of each channel in the wireless device is also independent. If a channel is shared by multiple wireless device controllers, the channel power must also be shared by these multiple wireless device controllers. Therefore, in practical applications, channel resources and power resources are generally considered together for sharing. In one possible implementation, channel resources and power resources are combined into a single channel power resource. For example, the power allocated to channel A at 1.8 GHz is 20 W, while the power allocated to channel A at 2.1 GHz is 40 W.

[0196] In addition, carrier resources refer to the number of carriers that a wireless device can process. The carrier resources are mainly intermediate frequency digital resources, which are used to perform frequency conversion / clipping / pre-distortion and other processing on each carrier. For example, take the maximum carrier resource of a wireless device as 4 (that is, the wireless device can process up to 4 carriers). Assume that the frequency band resources corresponding to a wireless device controller are 2.1GHz 2130~2150 20M and 1.8GHz 1830~1850 20M. If the wireless device controller chooses to establish 1 2.1GHz 20M carrier and 1 1.8GHz 20M carrier, the carrier resources that the wireless device needs to consume are 2; if the wireless device controller chooses to establish 2 2.1GHz 10M carriers and 2 1.8GHz 10M carriers, the carrier resources that the wireless device needs to consume are 4. When multiple wireless device controllers share carrier resources, the more one wireless device controller uses, the less available to other wireless device controllers. This may even cause other wireless device controllers to be unable to successfully establish carriers due to a lack of carrier resources even though they have spectrum / power resources.

[0197] Furthermore, the number of flow resources refers to the number of end-user service flows that a wireless device can handle simultaneously. This includes both uplink and downlink flow resources. Uplink flow resources refer to the number of uplink service flows from end-users that a wireless device can handle simultaneously. Downlink flow resources refer to the number of downlink service flows from end-users that a wireless device can handle simultaneously.

[0198] It should be understood that stream resources are a type of baseband processing resource. Only when a wireless device has baseband processing capabilities, for example, when the wireless device controller is an AAU, can the wireless device share stream resources with multiple wireless device controllers. Generally, the more stream resources a wireless device controller receives, the more end-user data the wireless device can process for that wireless device controller, thereby providing a better communication experience for the user.

[0199] It should be understood that the aforementioned physical resources are merely examples listed for the convenience of readers' understanding. In actual applications, the wireless device may also provide other types of physical resources for the aforementioned at least two wireless device controllers. This application does not specifically limit the physical resources provided by the wireless device.

[0200] In addition, for examples of frequency band resources, power resources, channel resources, carrier resources, and stream number resources, please refer to the previous article. Figure 2A The relevant introduction of the corresponding embodiments will not be repeated here.

[0201] The carrier establishment request includes the identifier of the first wireless equipment controller, where the identifier of the first wireless equipment controller is used to indicate an application for physical resources corresponding to the first wireless equipment controller.

[0202] Optionally, if the information of physical resources corresponding to different wireless device controllers in the first resource table is stored in different storage locations, the wireless device can only query the storage page of the physical resources corresponding to the first wireless device controller in the storage module based on the identifier of the first wireless device controller, without traversing the storage location of the entire first resource table.

[0203] Optionally, the wireless device may also perform a validity check on the corresponding carrier establishment request based on the identifier of the first wireless device controller. For example, the wireless device may determine, based on the identifier of the first wireless device controller, whether the carrier establishment request originates from the wireless device controller indicated by the identifier of the first wireless device controller. This helps prevent other wireless device controllers from maliciously forging the carrier establishment request of the first wireless device controller, thereby affecting the carrier establishment of the first wireless device controller.

[0204] In addition, the carrier establishment request also carries some information required for establishing the first carrier.

[0205] In a possible implementation manner, the carrier establishment request further includes a first carrier parameter, where the first carrier parameter is used to indicate a feature of the first carrier.

[0206] For example, if operator 1 configures a 20 MHz FDD LTE 2T2R carrier on the first wireless device controller through the network management device, using a transmit frequency of 2110 MHz to 2130 MHz and a receive frequency of 1920 MHz to 1940 MHz, the first carrier parameters in the carrier establishment request are: "Bandwidth = 20 MHz, Duplex Mode = FDD, Standard = LTE, Transmit Mode = 2T, Receive Mode = 2R, Frequency Band = 2.1 GHz."

[0207] It should be understood that the wireless device generally does not directly establish the first carrier using the first carrier parameters. Generally, the wireless device first converts the first carrier parameters into first physical resource information, and then generates the first carrier based on the first physical resource information. For details, please refer to the relevant description of step 602 below.

[0208] In another possible implementation, the carrier establishment request further includes first physical resource information.

[0209] For example, if operator 1 configures a 20M bandwidth FDD LTE 2T2R carrier on the first wireless device controller through the network management device, using a transmission frequency of 2110MHz to 2130MHz and a reception frequency of 1920MHz to 1940MHz. At this time, if the carrier establishment request directly carries the first physical resource information, the first physical resource information in this example includes: frequency band resources are "2.1GHz transmission frequency 1950MHz to 1970MHz, reception frequency 2140MHz to 2160MHz", power resources are "2.1GHz 20W / per channel", channel resources are "2.1GHz 2T", uplink flow number resources are "4 flows", and downlink flow number resources are "4 flows".

[0210] Specifically, for the introduction of the first carrier parameter and the first physical resource information, please refer to the previous text. Figure 2A and Figure 2B The relevant introduction in will not be repeated here.

[0211] Step 602: The wireless device determines first physical resource information according to the carrier establishment request.

[0212] The first physical resource information is used to indicate the physical resources required to establish the first carrier. It should be understood that the first physical resource information may indicate one physical resource or multiple physical resources. Physical resources include, but are not limited to, frequency band resources, power resources, channel resources, carrier resources, and stream number resources. Therefore, the first physical resource information includes information on at least one of the following: frequency band resources, power resources, channel resources, carrier resources, and stream number resources.

[0213] In addition, for explanations of frequency band resources, power resources, channel resources, carrier resources, and stream number resources, please refer to the relevant introduction in step 601 in the previous figure, which will not be repeated here.

[0214] In this embodiment, the contents carried in the carrier establishment request are different, and the wireless device determines the first physical resource information in different ways.

[0215] In one possible implementation, the carrier establishment request carries a first carrier parameter, where the first carrier parameter is used to indicate characteristics of the first carrier. In this case, the wireless device generates the first physical resource information based on the first carrier parameter and a preset rule corresponding to the first wireless device controller, where different wireless device controllers among the at least two wireless device controllers correspond to different preset rules.

[0216] Among them, the preset rules can be understood as the processing logic of the service processing module (which can also be understood as the service processing software) in the wireless device, and different service processing modules correspond to different wireless device controllers. If different service processing modules have different service processing logics, then different service processing modules correspond to different preset rules. In this embodiment, the preset rules can be understood as the rules for converting the first carrier parameters into the first wireless resource information. If the first carrier parameters are input into the service processing module corresponding to another wireless device controller (for example, the second service processing module corresponding to the second wireless device controller), the second service processing module may not be able to recognize the aforementioned first carrier parameters, and may also be unable to convert the aforementioned first carrier parameters into the first physical resource information.

[0217] In another possible implementation, the carrier establishment request directly carries the first physical resource information. In this case, the wireless device directly obtains the first physical resource information from the carrier establishment request.

[0218] In this embodiment, two implementation methods of carrier establishment request are proposed, and two implementation methods of determining first physical resource information are also provided accordingly. In actual applications, the wireless device can use any of the above implementation methods, which are not specifically limited here.

[0219] Step 603: The wireless device determines whether to establish the first carrier according to the first physical resource information and the physical resources corresponding to the first wireless device controller.

[0220] The at least two wireless device controllers correspond to different physical resources in the wireless device. That is, different wireless device controllers can use different physical resources in the wireless device, i.e., the physical resources in the wireless device are divided among the at least two wireless device controllers, and the at least two wireless device controllers correspond to different physical resources in the wireless device. That is, information such as which wireless device controllers the physical resources in the wireless device are divided to and which physical resources each wireless device controller is allowed to use is determined. Therefore, when the wireless device learns, based on the first physical resource information, which physical resources the first wireless device controller needs to use when applying to establish a first carrier, the wireless device needs to determine the relationship between the physical resources indicated by the first physical resource information and the physical resources corresponding to the first wireless device controller in the wireless device to determine whether to establish the first carrier.

[0221] In this embodiment, the wireless device stores a first resource table that includes the physical resources corresponding to each of the at least two wireless device controllers. Specifically, the wireless device uses the first resource table to determine the physical resources corresponding to each wireless device controller. Specifically, the wireless device records the physical resources available to each wireless device controller in the first resource table. For details about the first resource table, please refer to Table 1-1 above and will not be further elaborated here.

[0222] Exemplarily, the first resource table is pre-selected and configured by a user, or can be dynamically generated by the wireless device. For example, before the wireless device receives a carrier establishment request from a first wireless device controller, the wireless device obtains a resource configuration message including the first resource table.

[0223] Because the carrier establishment request includes the identifier of the first wireless device controller, which indicates a request for physical resources corresponding to the first wireless device controller, the wireless device first queries the first resource table for the physical resources corresponding to the first wireless device controller based on the identifier of the first wireless device controller. The wireless device then determines whether to establish the first carrier based on the amount of physical resources indicated by the first physical resource information and the amount of physical resources corresponding to the first wireless device controller in the first resource table.

[0224] The wireless device may determine whether to establish the first carrier in the following two ways:

[0225] In one implementation, when the amount of physical resources indicated by the first physical resource information is less than the amount of physical resources corresponding to the first wireless device controller, the wireless device determines to allow establishment of the first carrier, and the wireless device executes steps 604 and 605 .

[0226] In another implementation, when the amount of physical resources indicated by the first physical resource information is greater than the amount of physical resources corresponding to the first wireless device controller, the wireless device determines that the physical resources corresponding to the first wireless device controller are insufficient to establish the first carrier, and the wireless device executes steps 604 and 605 and only executes step 606.

[0227] Step 604: The wireless device establishes the first carrier using the physical resources indicated by the first physical resource information.

[0228] In this step, when the amount of physical resources indicated by the first physical resource information is less than the amount of physical resources corresponding to the first wireless device controller, the wireless device determines that the first carrier is allowed to be established, and establishes the first carrier through the digital processing module and analog processing module in the wireless device. The digital processing module includes circuits or devices with digital signal processing capabilities, such as an upconverter, a downconverter, and a digital-to-analog converter. The analog processing module includes circuits or devices with analog signal processing capabilities, such as an intermediate frequency amplifier, a filter, a mixer, and a power amplifier.

[0229] The present application does not limit the implementation method of the wireless device using physical resources to establish the first carrier. The method of establishing the first carrier by the digital processing module and the analog processing module in the wireless device can refer to the method in the traditional technology.

[0230] Step 605: The wireless device updates the amount of the physical resource corresponding to the first wireless device controller in the first resource table according to the amount of the physical resource indicated by the first physical resource information.

[0231] In this embodiment, after determining that establishment of the first carrier based on the first physical resource information is permitted, the wireless device further updates the resource quantity of the physical resource corresponding to the first wireless device controller in the first resource table based on the resource quantity of the physical resource indicated by the first physical resource information. Specifically, the wireless device subtracts the resource quantity of the physical resource indicated by the first physical resource information from the resource quantity of the physical resource corresponding to the first wireless device controller in the first resource table to obtain an updated resource quantity of the physical resource corresponding to the first wireless device controller.

[0232] Optionally, the wireless device further stores first physical resource information to record the physical resources used to establish the first carrier.

[0233] Step 606: The wireless device sends a carrier establishment response to the first wireless device controller.

[0234] In one possible implementation, if the wireless device determines in step 603 that the physical resources corresponding to the first wireless device controller are insufficient to establish the first carrier, the wireless device sends a carrier establishment response to the first wireless device controller. The carrier establishment response carries information indicating that the first carrier establishment failed. In this implementation, step 606 has no specific time sequence with steps 604 and 605; step 606 can be performed after step 603.

[0235] In another possible implementation, if the wireless device determines in step 603 that the physical resources corresponding to the first wireless device controller are sufficient to establish the first carrier, and the wireless device successfully establishes the first carrier in step 604, the wireless device sends a carrier establishment response to the first wireless device controller. The carrier establishment response carries content indicating the successful establishment of the first carrier. In this implementation, there is no specific time sequence for step 606 and step 605; step 606 can be performed after step 604.

[0236] In this embodiment, a wireless device can connect to multiple wireless device controllers and receive a carrier establishment request from one of the multiple wireless device controllers. Based on the carrier establishment request, the wireless device determines physical resources for establishing a carrier, and then determines whether to establish a carrier based on the physical resources and the physical resources corresponding to the wireless device controller in the wireless device. This allows multiple wireless device controllers to share a single wireless device, increasing the flexibility of wireless device controllers in managing wireless devices.

[0237] In one possible implementation, a wireless device controller may query the usage of physical resources corresponding to the wireless device controller. Specifically, the wireless device receives a resource query message from the first wireless device controller, the resource query message being used to query the wireless device for usage information of the physical resources corresponding to the first wireless device, the resource query message including an identifier of the first wireless device controller; the wireless device queries the first resource table for usage information of the physical resources corresponding to the first wireless device controller; and the wireless device sends the usage information of the physical resources corresponding to the first wireless device controller to the first wireless device controller.

[0238] In this embodiment, each service processing module can query the physical resource usage information of a wireless device controller and provide feedback to the wireless device controller. This helps prevent wireless devices from misreporting the physical resource usage of the wireless device controller to the wireless device controller.

[0239] In one possible implementation, the wireless device may also report fault information at the granularity of a wireless device controller. Specifically, the wireless device obtains fault information indicating at least one physical resource in the wireless device that has a fault; the wireless device determines at least one second wireless device controller from the at least two wireless device controllers, the second wireless device controller being the wireless device controller that uses the physical resource indicated by the fault information; and the wireless device sends the fault information to the second wireless device controller.

[0240] This embodiment proposes that a wireless device can detect a physical resource failure and, based on the physical resource failure, determine the scope of the failure, specifically which wireless device controllers (referred to in this embodiment as the second wireless device controller) are affected by the failed physical resource. The wireless device then sends fault information only to the second wireless device controller, without sending fault information to other wireless device controllers. This embodiment facilitates accurate fault reporting by the wireless device to the wireless device controller, avoiding the need for the wireless device to report faults to all wireless device controllers connected to the wireless device.

[0241] In addition, the present application provides a computer program product, which includes one or more computer instructions.
