Description

[Technical field]

[0001] The present application relates to the field of communications, and in particular to a communication method, a communication device, and a communication system, as well as a storage medium. [Background technology]

[0002] The base station includes a baseband unit and a radio unit. The baseband unit performs baseband processing, interaction with the core network, and other functions. The radio unit performs signal modulation, radio frequency transmission, and other functions. The baseband unit may further schedule the radio unit for transmission of air interface services and periodically or aperiodically perform component processing tasks on the radio unit. The component processing tasks include tasks for calibrating radio frequency channels of the radio unit, tasks for detecting the status of components in the radio unit, and / or the like.

[0003] Currently, the baseband unit may allocate resources and use the allocated resources to perform transmission of air interface services between the baseband unit and the wireless unit. Alternatively, the baseband unit may actively suspend transmission of air interface services to the wireless unit and use the resources that are dormant during the suspension of the air interface services to perform component processing tasks on the wireless unit. For example, the baseband unit calibrates the radio frequency channel of the wireless unit and / or detects components in the wireless unit.

[0004] As technology advances, wireless units become more and more autonomous, and may have requirements for autonomously using resources. For example, a wireless unit may require resources to autonomously perform component processing tasks, or a wireless unit may require resources for power saving, fault recovery, or the like. However, in the current situation, the requirements of a wireless unit for autonomously using resources cannot be met. Summary of the Invention

[0005] The present application provides a communication method, a communication device, a communication system, and a storage medium to meet the requirements of a wireless unit for autonomously using resources.

[0006] According to a first aspect, the present application provides a communication method, in which a wireless unit transmits an out-of-service request to a baseband unit, the wireless unit receives an out-of-service grant response transmitted by the baseband unit, the out-of-service grant response indicating that a first resource is an out-of-service resource, or the wireless unit receives an out-of-service rejection response transmitted by the baseband unit, the out-of-service rejection response including a delay duration, and resends the out-of-service request to the baseband unit after a first time point, the first time point being after a second time point, the duration between the first time point and the second time point being equal to or greater than the delay duration, and the second time point being a time point at which the wireless unit receives the out-of-service rejection response.

[0007] The radio unit sends a service suspension request to the baseband unit. If the service is allowed to be suspended, the baseband unit sends a service suspension permission response to the radio unit, where the service suspension permission response indicates that the first resource is a suspended resource. In this way, after the radio unit receives the service suspension permission response, both the baseband unit and the radio unit recognize that the first resource is a suspended resource. The baseband unit may stop transmitting the first service using the first resource, where the first service is a service of the radio unit, and the radio unit may use the first resource autonomously. In this way, interference with the first service is avoided when the radio unit uses the first resource autonomously. For example, the radio unit uses the first resource to autonomously perform a component processing task. This satisfies the requirement of the radio unit to autonomously perform the component processing task, and interference with the first service is avoided when performing the component processing task.

[0008] Alternatively, if the baseband unit rejects the request to pause the service, the baseband unit transmits a pause-of-service rejection response to the wireless unit. Since the pause-of-service rejection response includes a delay duration, the wireless unit resends the pause-of-service request after delaying for a time period starting from a second time point when the pause-of-service rejection response is received. To prevent the wireless unit from frequently transmitting pause-of-service requests to the baseband unit, the duration of the time period is equal to or greater than the delay duration.

[0009] In a possible implementation, the wireless unit executes a first component processing task using the first resource, the first component processing task including one or more of the following: a task for calibrating a radio frequency channel of the wireless unit, a task for calibrating an antenna of the wireless unit, or a task for detecting components in the wireless unit, and since the baseband unit stops transmitting the first service using the first resource, the wireless unit executes the first component processing task using the first resource in a manner to avoid interference with the first service.

[0010] In another possible implementation, the service idling rejection response further includes the rejection reason of the baseband unit. If the rejection reason is not that the baseband unit does not have the service outage function, the wireless unit resends the service outage request to the baseband unit after the first time point. In this way, if the baseband unit does not have the service outage function, the wireless unit avoids repeatedly sending the service outage request to waste network resources.

[0011] In another possible implementation, the first resource includes a first radio frequency channel, a first time resource, and a first frequency resource, and the first radio frequency channel is a radio frequency channel on the wireless unit.

[0012] In another possible implementation, the service outage permission response includes first information, and the first information indicates a first resource. In this way, the wireless unit obtains the first resource based on the first information, and ensures that the first resource obtained by the wireless unit is consistent with the first resource determined by the baseband unit, and ensures that the baseband unit does not use the first resource to transmit the first service when the wireless unit uses the first resource.

[0013] In another possible implementation, the first information includes one or more of the following information: a channel identifier of the first radio frequency channel, a start time of the first time resource, a duration of the first time resource, a start position of the first frequency resource, or a resource size of the first frequency resource.

[0014] In another possible implementation, the first information includes one or more of the following information: a channel identifier of the first radio frequency channel, a start time of the first time resource, a duration of the first time resource, or at least one frequency identifier within the first frequency resource.

[0015] In another possible implementation, before the wireless unit executes the first component processing task using the first resource, the wireless unit determines the first resource based on the first information.

[0016] In another possible implementation, the out-of-service request includes the second information and / or a task identifier of the first component processing task, the second information indicating the second resource, and the first component processing task including one or more of the following: a task for calibrating a radio frequency channel of the wireless unit, a task for calibrating an antenna of the wireless unit, or a task for detecting a component in the wireless unit. Because the out-of-service request includes the second information and / or the task identifier of the first component processing task, the baseband unit may determine resources required by the wireless unit to execute the first component processing task based on the second information and / or the task identifier of the first component processing task to avoid an excess or shortage of resources determined by the baseband unit.

[0017] In another possible implementation, the second resource includes a first radio frequency channel, a second time resource, and a second frequency resource, and the first radio frequency channel is a radio frequency channel on the wireless unit.

[0018] In another possible implementation, the second information includes one or more of the following information: A channel identifier of the first radio frequency channel, a start time of the second time resource, a duration of the second time resource, a start position of the second frequency resource, or a resource size of the second frequency resource.

[0019] In another possible implementation, the second information includes one or more of the following information: A channel identifier of the first radio frequency channel, a start time of the second time resource, a duration of the second time resource, or at least one frequency identifier within the second frequency resource.

[0020] In another possible implementation, the wireless unit determines the second information based on the first component processing task, the second information may indicate resources required by the wireless unit to perform the first component processing task so as to avoid an excess or shortage of resources determined by the baseband unit.

[0021] In another possible implementation, the wireless unit transmits a task identifier of the first component processing task and the second information to the baseband unit. In this way, the baseband unit knows, via the second information, the specific resources required by the wireless unit to process the first component processing task. In this way, when the wireless unit transmits a service outage request, the service outage request includes the task identifier of the first component processing task, and the baseband unit determines the first resources required by the wireless unit based on the task identifier.

[0022] According to a second aspect, the present application provides a communication method, in which a baseband unit receives a service outage request sent by a wireless unit. If the baseband unit allows the service to be out of service, the baseband unit determines a first resource based on the service outage request and sends a service outage permission response to the wireless unit, the service outage permission response indicating that the first resource is the outage resource. If the baseband unit rejects the service being out of service, the baseband unit sends a service outage rejection response to the wireless unit, the service outage rejection response including a delay duration.

[0023] After receiving the service suspension request, the baseband unit determines the first resource, and if it allows the service to be suspended, sends a service suspension permission response to the wireless unit, where the service suspension permission response indicates that the first resource is a suspended resource. In this way, after the wireless unit receives the service suspension permission response, both the baseband unit and the wireless unit recognize that the first resource is a suspended resource. The baseband unit may stop transmitting the first service using the first resource, where the first service is a service of the wireless unit, and the wireless unit may use the first resource autonomously. In this way, when the wireless unit uses the first resource autonomously, interference with the first service is avoided. For example, the wireless unit uses the first resource to autonomously perform a component processing task. This satisfies the requirement of the wireless unit to autonomously perform the component processing task, and interference with the first service is avoided when performing the component processing task.

[0024] Alternatively, if the baseband unit rejects the request to suspend service, the baseband unit sends a suspend service reject response to the wireless unit. Since the suspend service reject response includes a delay duration, after receiving the suspend service reject response, the wireless unit resends the suspend service request after delaying for a certain time period. To prevent the wireless unit from frequently sending suspend service requests to the baseband unit, the duration of the time period is equal to or greater than the delay duration.

[0025] In a possible implementation, the first resource includes a first radio frequency channel, a first time resource, and a first frequency resource, and the first radio frequency channel is a radio frequency channel on a wireless unit.

[0026] In another possible implementation, the service outage permission response includes first information, and the first information indicates a first resource, thus ensuring that the first resource recognized by the wireless unit matches the first resource of the baseband unit, and ensuring that the baseband unit does not use the first resource to transmit the first service when the wireless unit uses the first resource.

[0027] In another possible implementation, the first information includes one or more of the following information: A channel identifier of the first radio frequency channel, a start time of the first time resource, a duration of the first time resource, a start position of the first frequency resource, or a resource size of the first frequency resource.

[0028] In another possible implementation, the first information includes one or more of the following information: A channel identifier of the first radio frequency channel, a start time of the first time resource, a duration of the first time resource, or at least one frequency identifier within the first frequency resource.

[0029] In another possible implementation, the baseband unit stops transmitting a first service using a first frequency resource during a time period corresponding to a first time resource, the first service being a service of the wireless unit, thereby preventing the wireless unit from interfering with the first service during that time period.

[0030] In another possible implementation, the out-of-service rejection response further includes the rejection reason of the baseband unit, and the wireless unit resends the out-of-service request to the baseband unit only if the rejection reason is not that the baseband unit does not have the out-of-service function. In this way, if the baseband unit does not have the out-of-service function, the wireless unit avoids repeatedly sending the out-of-service request to waste network resources.

[0031] In another possible implementation, the out-of-service request includes the second information and / or a task identifier of the first component processing task, the second information indicating the second resource, and the first component processing task including one or more of the following: a task for calibrating a radio frequency channel of the wireless unit, a task for calibrating an antenna of the wireless unit, or a task for detecting a component in the wireless unit. Because the out-of-service request includes the second information and / or the task identifier of the first component processing task, the baseband unit may determine resources required by the wireless unit to execute the first component processing task based on the second information and / or the task identifier of the first component processing task to avoid an excess or shortage of resources determined by the baseband unit.

[0032] In another possible implementation, the second resource includes a first radio frequency channel, a second time resource, and a second frequency resource, and the first radio frequency channel is a radio frequency channel on the wireless unit.

[0033] In another possible implementation, the second information includes one or more of the following information: A channel identifier of the first radio frequency channel, a start time of the second time resource, a duration of the second time resource, a start position of the second frequency resource, or a resource size of the second frequency resource.

[0034] In another possible implementation, the second information includes one or more of the following information: A channel identifier of the first radio frequency channel, a start time of the second time resource, a duration of the second time resource, or at least one frequency identifier within the second frequency resource.

[0035] In another possible implementation, the baseband unit determines whether the transmission of the first service can be suspended based on the service information of the first service, and the first service is a service of the wireless unit. If it is determined that the transmission of the first service can be suspended, i.e., the service is allowed to be suspended, the baseband unit determines the first resource based on the service suspension request. The first resource is determined only if the first service is allowed to be suspended. This reduces the impact on the first service.

[0036] In another possible implementation, the out-of-service request includes second information. The baseband unit determines the second resource as the first resource based on the second information, or the baseband unit assigns a resource different from the second resource as the first resource based on the second information. Because the out-of-service request includes the second information, the baseband unit may determine the resource required by the radio unit to perform the first component processing task based on the second information to avoid an excess or shortage of resources determined by the baseband unit.

[0037] In another possible implementation, the service outage request includes a task identifier of a first component processing task. The baseband unit obtains corresponding information from a correspondence between the task identifiers and the second information based on the task identifier of the first component processing task. The baseband unit determines the first resource based on the obtained information. Because the service outage request includes the task identifier of the first component processing task, the baseband unit may determine resources required by the radio unit to execute the first component processing task based on the task identifier of the first component processing task to avoid excess or shortage of resources determined by the baseband unit.

[0038] In another possible implementation, the baseband unit receives the task identifier of the first component processing task and the second information transmitted by the wireless unit. The baseband unit stores a correspondence between the task identifier of the first component processing task and the second information. In this way, the baseband unit knows the specific resources required by the wireless unit to process the first component processing task via the second information. In this way, when the out-of-service request includes the task identifier of the first component processing task, the baseband unit determines the first resources required by the wireless unit based on the task identifier.

[0039] According to a third aspect, the present application provides a communication device configured to perform the method according to the first aspect or any one of its possible implementations, in particular the device includes a unit configured to perform the method according to the first aspect or any one of its possible implementations.

[0047] Hereinafter, the embodiments of the present application will be described in more detail with reference to the accompanying drawings.

[0048] Please refer to Fig. 1. An embodiment of the present application provides a network architecture 100. The network architecture 100 includes: It includes a baseband unit (BBU) 101 and a radio unit (RU) 102, where the baseband unit 101 communicates with the radio unit 102.

[0049] In some embodiments, the baseband unit 101 has functions such as baseband processing and interaction with the core network. The radio unit 102 has functions such as signal modulation and radio frequency transmission. In this way, the baseband unit 101 and the radio unit 102 may be configured for service transmission. For example, the baseband unit 101 receives service data transmitted from the core network, performs baseband processing on the received service data to convert the service data into a baseband signal, and transmits the baseband signal to the radio unit 102. The radio unit 102 receives the baseband signal, converts the baseband signal into a radio frequency signal, and transmits the radio frequency signal to the terminal. Alternatively, the radio unit 102 receives a radio frequency signal transmitted by the terminal, converts the radio frequency signal into a baseband signal, and transmits the baseband signal to the baseband unit 101. The baseband unit 101 receives the baseband signal, performs baseband processing on the baseband signal to obtain service data, and transmits the service data to the core network.

[0050] In some embodiments, there are one or more radio units 102, i.e., the network architecture 100 includes one or more radio units 102, and the baseband unit 101 can communicate with each radio unit 102 included in the network architecture 100.

[0051] In some embodiments, the baseband unit 101 and the radio unit 102 may or may not be equipment from the same vendor.

[0052] In some embodiments, the baseband unit 101 may be a radio access network distribution unit ( radio access network distributed unit, DU), radio access network central unit ( radioaccess network central unit (CU), or the like, and the radio unit 102 is a radio access network remote radio unit ( radio access network remote radio unit (RRU), active antenna unit (AAU), or similar.

[0053] See Fig. 2. The radio unit 102 includes a processing unit 1021 and at least one communication module, where each communication module includes a radio frequency channel 1022. Optionally, the radio frequency channel 1022 includes a transmit radio frequency channel 1022A and a receive radio frequency channel 1022B, where both the transmit radio frequency channel 1022A and the receive radio frequency channel 1022B are connected to the processing unit 1021.

[0054] In some embodiments, each communication module further includes a phase shifter 1023, an antenna 1024, and other components. The phase shifter 1023 is connected to the radio frequency channel 1022 and the antenna 1024. Optionally, both the transmit radio frequency channel 1022A and the receive radio frequency channel 1022B are connected to the phase shifter 1023.

[0055] In some embodiments, the process of the radio unit 102 transmitting a radio frequency signal is as follows: the processing unit 1021 transmits a radio frequency signal on the transmit radio frequency channel 1022A; the phase shifter 1023 receives the radio frequency signal from the transmit radio frequency channel 1022A and modulates the phase of the radio frequency signal; the antenna 1024 transmits the phase-modulated radio frequency signal.

[0056] In some embodiments, the process of the radio unit 102 receiving a radio frequency signal is as follows: the antenna 1024 receives a radio frequency signal. The phase shifter 1023 modulates the phase of the radio frequency signal received by the antenna 1024, and transmits the phase-modulated radio frequency signal on the receive radio frequency channel 1022B. The processing unit 1021 receives the radio frequency signal from the receive radio frequency channel 1022B.

[0057] The wireless unit 102 includes one or more cells, each corresponding to one or more communication modules. For any cell, the wireless unit 102 communicates with terminals located within the cell by using the one or more communication modules corresponding to the cell.

[0058] In some embodiments, the processing unit 1021 is a processor. For example, the processing unit 1021 may be a general-purpose central processing unit (CPU), a network processor (NP), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to control program execution in the solutions of the present application.

[0059] In some embodiments, for any communication module in the wireless unit 102, the communication module further includes a loopback unit 1025, a detection unit 1026, and / or the like.

[0060] The loopback unit 1025 is connected to the transmit radio frequency channel 1022A and the receive radio frequency channel 1022B. The loopback unit 1025 is configured to couple a radio frequency signal transmitted on the transmit radio frequency channel 1022A to the receive radio frequency channel 1022B.

[0061] The detection unit 1026 is disposed between the phase shifter 1023 and the antenna 1024, and is separately connected to the phase shifter 1023 and the antenna 1024. The detection unit 1026 is configured to detect the phase of the radio frequency signal transmitted by the phase shifter 1023 to the antenna 1024.

[0062] In some embodiments, the loopback unit 1025 is a combined loopback circuit or the like, and the detection unit 1026 is a combined detection circuit or the like.

[0063] It should be noted that with the development of technology, the radio unit 102 becomes more and more autonomous and has a requirement to autonomously execute tasks using resources. For ease of explanation, the resource is referred to as a first resource, and the first resource includes a first radio frequency channel, a first time resource, a first frequency resource, and the like.

[0064] For example, the tasks include a component processing task, a troubleshooting task, and / or a power saving processing task. The wireless unit 102 may require the first resource to perform the component processing task, or the wireless unit 102 may require the first resource to perform the troubleshooting task, or the wireless unit 102 may require the first resource to perform the power saving processing task, or the like.

[0065] The component processing task is used to perform processing, such as calibration or detection, on the components contained in the wireless unit 102 .

[0066] In some embodiments, the component processing tasks include one or more of the following: a task for calibrating a radio frequency channel 1022 of the wireless unit 102, a task for calibrating an antenna 1024 of the wireless unit 102, a task for detecting components within the wireless unit 102, or the like.

[0067] In some embodiments, the task to detect components within the wireless unit 102 includes one or more of the following: a task to detect a phase shifter 1023 within the wireless unit 102, a task to detect an antenna 1024 within the wireless unit 102, or the like.

[0068] The radio unit 102 only needs to start executing the loopback unit 1025 or the detection unit 1026 in some cases. For example, the radio unit 102 starts executing the loopback unit 1025 only when the radio unit 102 needs to perform a task to calibrate the radio frequency channel 1022. In this case, the loopback unit 1025 can combine the radio frequency signal transmitted on the transmit radio frequency channel 1022A into the receive radio frequency channel 1022B.

[0069] As another example, the radio unit 102 starts executing the detection unit 1026 only when the radio unit 102 needs to execute a task to detect the phase shifter 1023. In this case, the detection unit 1026 can detect the phase of the radio frequency signal transmitted by the phase shifter 1023 to the antenna 1024.

[0070] The troubleshooting task is used to detect and correct failures that occur in the radio unit 102. For example, if the radio unit 102 loses clock synchronization, if the clock is unavailable, or if the clock level does not meet the requirements, services cannot be transmitted between the baseband unit 101 and the radio unit 102. In this case, the radio unit 102 may request a first resource to select a clock source and / or perform the process of clock synchronization.

[0071] The power saving processing task is used to disable some components in the wireless unit 102. For example, the wireless unit 102 disables a first radio frequency channel included in the first resource during a time period corresponding to a first time resource included in the first resource. In this case, the first frequency resource in the first resource is all frequency resources on the wireless unit 102, and the disabled first radio frequency channel transmits a radio frequency signal that does not use all frequency resources on the wireless unit 102.

[0072] When the radio unit 102 needs to use the first resource, the radio unit 102 must first request the first resource from the baseband unit 101. The first resource is a dormant resource. In this way, the baseband unit 101 and the radio unit 102 perform a service transmission that does not use the first resource. In this way, when using the first resource to perform a component processing task, a troubleshooting task, a power saving processing task, or the like, the radio unit 102 does not interfere with the service between the baseband unit 101 and the radio unit 102.

[0073] In some embodiments, the wireless unit 102 sends an out-of-service request to the baseband unit 101. The baseband unit 101 receives the out-of-service request, determines a first resource based on the out-of-service request, and sends an out-of-service authorization response to the wireless unit, where the out-of-service authorization response indicates that the first resource is an out-of-service resource. The wireless unit 102 receives the out-of-service authorization response and determines the first resource. In this manner, the wireless unit 102 implements the request for the first resource. Optionally, permission The response may include first information indicating the first resource. For a detailed process of the wireless unit 102 requesting the first resource, please refer to the description in any one of the following embodiments. The details will not be described again in this specification.

[0074] Please refer to Fig. 3. An embodiment of the present application provides a communication method 300. The method 300 is applied to the network architecture 100 shown in Fig. 1. A wireless unit in the network architecture 100 uses the method 300 to request a dormant resource from a baseband unit. The method 300 includes the following steps:

[0075] Step 301: The wireless unit sends an out-of-service request to the baseband unit.

[0076] In some embodiments, the wireless unit determines whether the baseband unit needs to suspend transmission of the service. If the baseband unit needs to suspend transmission of the service, the wireless unit sends a service suspension request to the baseband unit. Optionally, the service is a service between the baseband unit and the wireless unit. For example, the service is an air interface service between the baseband unit and the wireless unit.

[0077] The wireless unit may need to use resources to process a service, and when the wireless unit uses the resources, the transmission of the service needs to be interrupted to avoid interference with the service between the baseband unit and the wireless unit.

[0078] In some embodiments, the wireless unit performs component processing tasks periodically or aperiodically, and the wireless unit needs to use resources to perform the component processing tasks. When the wireless unit needs to perform the component processing tasks, the wireless unit needs the baseband unit to suspend transmission of services.

[0079] The component processing tasks include one or more of the following: a task for calibrating a radio frequency channel of a wireless unit, a task for calibrating an antenna of a wireless unit, a task for detecting components in a wireless unit, and the like, the components including phase shifters and the like, in other words, a task for detecting components in a wireless unit includes a task for detecting a phase shifter.

[0080] For example, if the radio unit needs to perform a task to calibrate a radio frequency channel, or needs to perform a task to calibrate an antenna, or needs to perform a task to detect a phase shifter, the radio unit needs to interrupt the service between the baseband unit and the radio unit and sends an out-of-service request to the baseband unit.

[0081] In some embodiments, the wireless unit may require resources to perform troubleshooting tasks, the wireless unit may require resources to perform power saving processing tasks, or the like. If the wireless unit needs to perform troubleshooting tasks or power saving processing tasks, it may also require the baseband unit to suspend transmission of services.

[0082] In some embodiments, the out-of-service request includes second information and / or a task identifier of the first task. The second information indicates a second resource, which is a resource that the wireless unit needs to request from the baseband unit. The first task is a task to be performed by the wireless unit. Optionally, the first task may be a component processing task, a troubleshooting task, a power saving processing task, or the like.

[0083] In some embodiments, the second resource includes a first radio frequency channel, a second time resource, a second frequency resource, and the like.

[0084] The second frequency resource is a frequency resource of all or a part of the wireless unit. Optionally, the second frequency resource may be a continuous frequency resource or a discrete frequency resource. For example, the second frequency resource is a continuous 50M frequency resource, or the second frequency resource is a continuous 100M frequency resource. As another example, the second frequency resource includes at least one frequency. For example, the second frequency resource includes one frequency, three frequencies, or five frequencies. In other words, the second frequency resource is a discrete frequency resource.

[0085] The first radio frequency channel is a radio frequency channel on the wireless unit. Optionally, the first radio frequency channel includes all or a portion of the radio frequency channel on the wireless unit.

[0086] In some embodiments, the second information includes one or more of the following information: A channel identifier of the first radio frequency channel, a start time of the second time resource, a duration of the second time resource, a start position of the second frequency resource, a resource size of the second frequency resource, or the like.

[0087] Alternatively, the second information includes one or more of the following information: A channel identifier for the first radio frequency channel, a start time of the second time resource, a duration of the second time resource, at least one frequency identifier within the second frequency resource, or the like.

[0088] In some embodiments, the wireless unit determines the second information based on the first task.

[0089] In some embodiments, the channel identifier of the first radio frequency channel includes a cell identifier of a cell to which the first radio frequency channel belongs, a number of the first radio frequency channel within the cell, and the like, or the channel identifier of the first radio frequency channel includes an identifier of a carrier used by the first radio frequency channel, and the like.

[0090] In some embodiments, the start time of the second time resource includes a frame number of the radio frame in which the starting point of the second time resource is located, a frame number of the subframe at the starting point within the radio frame, and a symbol number at the starting point within the subframe. The duration of the second time resource includes a quantity of symbols in the second time resource.

[0091] In general, a radio frame includes multiple subframes, and a subframe includes multiple symbols. A radio frame is a time period, and a time period includes multiple subperiods, and the multiple subperiods of a radio frame are multiple subframes of a radio frame. For each subframe, the subframe includes multiple subperiods, and the multiple subperiods of a subframe are multiple symbols of the subframe.

[0092] For example, if the duration of a radio frame is 10 ms and the radio frame includes 10 subframes, each subframe has a duration of 1 ms. For any subframe, assume that the subframe includes 14 symbols.

[0093] Step 302: The baseband unit receives a service outage request, and determines a first resource based on the service outage request.

[0094] In step 302, after receiving the service suspension request, the baseband unit judges whether to allow a first service to be suspended, the first service being a service transmitted between the baseband unit and the wireless unit. If the baseband unit allows the first service to be suspended, the baseband unit determines a first resource based on the service suspension request. If the baseband unit does not allow the first service to be suspended, the baseband unit stops determining the first resource.

[0095] The first resource determined by the baseband unit includes a first radio frequency channel, a first time resource, and a first frequency resource. The first time resource is a time period. Optionally, the time period includes one or more symbols.

[0096] The service suspension request may include the second information and / or the task identifier of the first task, or the service suspension request may not include the second information and the task identifier of the first task. In other words, the service suspension request has several cases as follows. Hereinafter, several cases will be described in detail separately.

[0097] Case 1: the service outage request does not include the second information and the task identifier of the first task.In case 1, after receiving the service outage request, the baseband unit allocates the first resource.

[0098] The baseband unit may or may not currently transmit the first service, where the first service is the service currently transmitted between the baseband unit and the radio unit.

[0099] If the baseband unit is not currently transmitting the first service, after receiving the service suspension request, the baseband unit directly allocates the first resource, in which case the first resource is a suspended resource.

[0100] When the baseband unit is currently transmitting a first service, the baseband unit determines whether interruption of the transmission of the first service is permitted based on service information of the first service, and allocates a first resource if interruption of the transmission of the first service is permitted.

[0101] If the baseband unit allows the transmission of the first service to be suspended, it indicates that the baseband unit allows the first service to be put into a paused state, or if the baseband unit does not allow the transmission of the first service to be suspended, it indicates that the baseband unit does not allow the first service to be put into a paused state.

[0102] In some embodiments, the service information of the first service includes a type and / or a priority of the first service, and the like. The baseband unit determines whether the first service is a service of a specified type based on the service information of the first service. If the first service is a service of the specified type, the baseband unit determines that interruption of transmission of the first service is not permitted, or if the first service is not a service of the specified type, the baseband unit determines that interruption of transmission of the first service is permitted.

[0103] In some embodiments, the specified type of service includes one or more of the following: low latency service, high reliability service, high priority service, or the like.

[0104] If the type of the first service is a low-latency service or a high-reliability service, the baseband unit determines that the first service is a service of the specified type and determines that interruption of the first service is not permitted. Alternatively, if the priority of the first service exceeds a priority threshold, the baseband unit determines that the first service is a high-priority service, determines that the first service is a service of the specified type and determines that interruption of the first service is not permitted. Alternatively, if the type of the first service is not a low-latency service and a high-reliability service and the priority of the first service does not exceed a priority threshold, the baseband unit determines that the first service is not a service of the specified type and determines that interruption of the transmission of the first service is permitted.

[0105] If the first service is a low-latency or high-reliability service, if the baseband unit interrupts the transmission of the first service, the service quality of the first service will be degraded, and the delay and reliability of the first service will be reduced, which may cause serious consequences, so the baseband unit does not allow the interruption of the first service.

[0106] The high priority service may be a service of a member user or an important service. If the baseband unit stops the service of the member user, the user experience of the member user may be affected. Therefore, the baseband unit does not allow the interruption of the first service. If the baseband unit interrupts the transmission of the important service, economic losses may be caused to the user. Therefore, the baseband unit does not allow the interruption of the first service. For example, the important service may be a control service used to control production equipment. If the baseband device interrupts the important service, the production equipment may stop production, and the production line used for the product may collapse, causing economic losses. Therefore, the baseband device does not allow the interruption of the transmission of the important service.

[0107] In some embodiments, the first information indicative of the first resource includes one or more of the following information: a channel identifier of the first radio frequency channel, a start time of the first time resource, a duration of the first time resource, a start position of the first frequency resource, or a resource size of the first frequency resource. Alternatively, in some embodiments, the first information includes one or more of the following information: a channel identifier of the first radio frequency channel, a start time of the first time resource, a duration of the first time resource, or at least one frequency identifier within the first frequency resource.

[0108] In some embodiments, the operation of the baseband unit to allocate the first resource is as follows.

[0109] For a first radio frequency channel included in the first resource, the baseband unit uses all radio frequency channels in the radio unit as the first radio frequency channel. In this case, since all radio frequency channels of the radio unit are idle, the radio unit may directly execute the first task using all or part of the radio frequency channels of the radio unit. The radio unit may not require the baseband unit to inform a specific channel of the first radio frequency channel. Therefore, the first information may include a channel identifier of the first radio frequency channel or may not include a channel identifier of the first radio frequency channel.

[0110] For a first time resource included in the first resource, the baseband unit determines a target duration interval, where the target duration is a maximum duration interval in the duration required by the wireless unit to process each task. The baseband unit determines a reception time at which the wireless unit receives an out-of-service authorization response, where the out-of-service request corresponds to the out-of-service authorization response. The baseband unit selects a time point as the start time based on a specified strategy, or randomly selects a time point as the start time, where the start time is not earlier than the reception time. And, the baseband unit allocates the first time resource based on the target duration interval and the start time, where the duration of the first time resource is equal to the target duration. In this case, since the duration of the first time resource is equal to the target duration, the duration actually required by the wireless unit to execute the first task is equal to or less than the duration of the first time resource. When executing the first task from the start time of the first time resource, the wireless unit can complete the execution of the first task within the first time resource, and the wireless unit may not need to recognize the actual duration of the first time resource. As such, the first information may or may not include the duration of the first time resource.

[0111] If the start time is a randomly selected time point, the first information includes the start time. If the start time is a time point selected based on a specified strategy, the wireless unit may alternatively determine the start time based on the specified strategy. Thus, the first information may or may not include the start time.

[0112] In some embodiments, for a specified strategy, the specified strategy instructs the baseband unit to use the time of reception as the start time, or instructs the baseband unit to add a specified duration to the time of reception to obtain the start time.

[0113] In some embodiments, for the receiving time point, the baseband unit determines a sending time point for sending the out-of-service authorization response, and determines the receiving time point based on the sending time point and an information transmission delay between the baseband unit and the wireless unit. For example, the baseband unit adds the information transmission delay to the sending time point to obtain the receiving time point. Optionally, the information transmission delay is obtained by the baseband unit through measurement in advance.

[0114] For a first frequency resource included in the first resource, the baseband unit determines a target resource size, and the target resource size is the maximum resource size in the size of resources required by the radio unit to process all tasks. Or, the baseband unit uses the start position of all frequency resources included in the radio unit as the start position of the first frequency resource. Or, the baseband unit uses a frequency position previously agreed upon by the baseband unit and the radio unit as the start position. And, the baseband unit allocates the first frequency resource based on the target resource size and the start position, and the size of the first frequency resource is equal to the target resource size. In this case, if the baseband unit does not notify the start position because the start position is the start position of all frequency resources or the agreed frequency position, the radio unit may determine the start position by itself. Therefore, the first information may include the start position or may not include the start position. Because the resource size of the first frequency resource is equal to the target resource size and the size of the resource actually required by the radio unit to execute the first task is equal to or less than the resource size of the first frequency resource, the radio unit may not need to recognize the resource size of the first frequency resource. Therefore, the first information may include a resource size of the first frequency resource, or may not include a resource size of the first frequency resource, or the baseband unit allocates at least one frequency, and a total size of the frequency resources of the at least one frequency is equal to the target resource size, and the baseband unit uses the at least one frequency as the first frequency resource.

[0115] In this case, the first information includes at least one frequency identifier.

[0116] In some embodiments, the radio unit may transmit at least one duration interval to the baseband unit before performing step 302. The at least one duration interval includes a duration required by the radio unit to process each task. The baseband unit receives the at least one duration interval and stores the at least one duration interval. Thus, in step 302, the baseband unit selects a maximum duration interval from the at least one duration interval as the target duration. Alternatively, the baseband unit selects a maximum duration interval from the at least one received duration interval and stores the maximum duration interval. Thus, in step 302, the baseband unit directly uses the stored maximum duration interval as the target duration.

[0117] In some embodiments, the radio unit may transmit at least one resource size to the baseband unit before performing step 302, where the at least one resource size includes a size of a resource required by the radio unit to process each task. The baseband unit receives the at least one resource size and stores the at least one resource size. Thus, in step 302, the baseband unit selects a maximum resource size from the at least one resource size as a target resource size. Alternatively, the baseband unit selects a maximum resource size from the received at least one resource size and stores the maximum resource size. Thus, in step 302, the baseband unit directly uses the stored maximum resource size as a target resource size.

[0118] In case 1, after determining the first resource, the baseband unit sends a service outage permission response to the wireless unit. The service outage permission response may include the first information or may not include the first information.

[0119] In some embodiments, when the first frequency resource includes at least one frequency, the outage permission response includes first information, the first information includes an identifier of the at least one frequency, the first information includes at least one frequency identifier, and the first information further includes information such as, for example, a start time of the first time resource, a duration of the first time resource, and / or a channel identifier of the first radio frequency channel. And / or, when the start time of the first time resource is a randomly selected time point, the outage permission response includes first information, the first information includes a start time of the first time resource, and the first information further includes information such as, for example, a duration of the first time resource, a channel identifier of the first radio frequency channel, and / or at least one frequency identifier within the first frequency resource (a resource size of the first frequency resource, and / or a start position of the first frequency resource).

[0120] Case 2: The service outage request includes the second information: In case 2, after receiving the service outage request, the baseband unit determines the first resource based on the second information.

[0121] In some embodiments, the baseband unit determines the second resource as the first resource based on the second information, or allocates a resource different from the second resource as the first resource based on the second information.

[0122] In some embodiments, the second resource indicated by the second information may be a dormant resource. Therefore, the baseband unit determines the second resource as the first resource. Alternatively, the second resource indicated by the second information is not a dormant resource, but the first service using the second resource may be interrupted. Therefore, the baseband unit determines the second resource as the first resource. Alternatively, if the second resource is a dormant resource or the first service can be interrupted, the baseband unit may assign a resource different from the second resource as the first resource.

[0123] The second information includes one or more parts of the content of a channel identifier of the first radio frequency channel, a start time of the second time resource, a duration of the second time resource, a start position of the second frequency resource, a resource size of the second frequency resource, and the like. Alternatively, the second information includes one or more parts of the content of a channel identifier of the first radio frequency channel, a start time of the second time resource, a duration of the second time resource, at least one frequency identifier within the second frequency resource, and the like. Some examples of specific content of the second information are listed below. Some examples are as follows, respectively.

[0124] Example 1: The second information includes a channel identifier of the first radio frequency channel, a start time of the second time resource, a duration of the second time resource, a start position of the second frequency resource, and a resource size of the second frequency resource. Alternatively, the second information includes a channel identifier of the first radio frequency channel, a start time of the second time resource, a duration of the second time resource, and at least one frequency identifier of the second frequency resource.

[0125] In example 1, the baseband unit determines, based on the second information, a second resource indicated by the second information. If there is no service using the second resource, which indicates that the second resource is an idle resource, the baseband unit determines the second resource as the first resource or assigns a resource different from the second resource as the first resource.

[0126] If the service uses the second resource, it indicates that the second resource is not a dormant resource. For ease of explanation, the service is called a first service, and the baseband unit determines whether the suspension of the transmission of the first service is permitted based on the service information of the first service. If the suspension of the transmission of the first service is permitted, it indicates that the baseband unit permits the first service to be dormant and determines the second resource as the first resource, or assigns a resource different from the second resource as the first resource. If the suspension of the transmission of the first service is not permitted, it indicates that the baseband unit does not permit the first service to be dormant.

[0127] In some embodiments, the first time resource included in the first resource allocated by the baseband unit and the second time resource included in the second resource are different. For example, the start time of the first time resource allocated by the baseband unit is earlier or later than the start time of the second time resource. In this case, if the start time of the first time resource is different from the start time of the second time resource, the first information includes the start position of the first time resource. Since the duration of the first time resource is the same as the duration of the second time resource, the first frequency resource is the same as the second frequency resource, and / or the first radio frequency channel in the first resource is the same as the first radio frequency channel in the second resource, the first information may not include or may include other content, such as the duration of the first time resource, a channel identifier of the first radio frequency channel, or at least one frequency identifier in the first frequency resource (the start position of the first frequency resource and / or the resource size of the first frequency resource).

[0128] In some embodiments, the first frequency resource included in the first resources and the second frequency resource included in the second resources allocated by the baseband unit are different.

[0129] For example, the starting position of the first frequency resource allocated by the baseband unit is different from the starting position of the second frequency resource. In this case, the first information includes the starting position of the first frequency resource. Since the resource size of the first frequency resource is the same as the resource size of the second frequency resource, the first time resource is the same as the second time resource, and / or the first radio frequency channel of the first resource is the same as the first radio frequency channel of the second resource, the first information may not include or may include other content, such as the resource size of the first frequency resource, the channel identifier of the first radio frequency channel, the start time of the first time resource, and / or the duration of the first time resource.

[0130] As another example, the frequencies included in the first frequency resource and the second frequency resource allocated by the baseband unit are completely or partially different. In this case, the first information includes at least one frequency identifier. Since the first time resource is the same as the second time resource and / or the first radio frequency channel in the first resource is the same as the first radio frequency channel in the second resource, the first information may not include or may include other content, such as a channel identifier of the first radio frequency channel, a start time of the first time resource, and / or a duration of the first time resource.

[0131] In example 1, when the first resource is the same as the second resource, the first information indicating the first resource is the same as the second information indicating the second resource. The out-of-service permission response sent by the baseband unit to the wireless unit may or may not include the first information.

[0132] Example 2: The second information includes a channel identifier of the first radio frequency channel, a duration of the second time resource, and a resource size of the second frequency resource.

[0133] In a second embodiment, the baseband unit determines whether to currently transmit a first service, and the first service is a service that uses a first radio frequency channel. If the first service is transmitted, the baseband unit determines whether interruption of transmission of the first service is permitted based on service information of the first service.

[0134] When the first service is not transmitted, or when the first service is transmitted but the baseband unit allows the transmission of the first service to be interrupted, the baseband unit determines the start time of the first time resource to obtain the first time resource, and the duration of the first time resource is equal to the duration of the second time resource. The baseband unit assigns the start position of the first frequency resource to obtain the first frequency resource, and the resource size of the first frequency resource is equal to the resource size of the second frequency resource. In this way, the first radio frequency channel, the first time resource, and the first frequency resource included in the first resource are obtained. When the first service is transmitted but the baseband unit does not allow the transmission of the first service to be interrupted, it indicates that the baseband unit does not allow the first service to be put into a dormant state.

[0135] In example 2, since the first radio frequency channel in the first resource is the same as the first radio frequency channel in the second resource, the resource size of the first frequency resource is the same as the resource size of the second frequency resource, and the duration of the first time resource is the same as the duration of the second time resource, the first information includes a start time of the first time resource and a start position of the first frequency resource. The first information may not include or may include other content, such as a channel identifier of the first radio frequency channel, a duration of the first time resource, and / or a resource size of the first frequency resource.

[0136] Example 3: The second information includes a duration of the second time resource and a resource size of the second frequency resource.

[0137] In example 3, the baseband unit determines whether a first service is currently transmitted, and the first service is a service between the baseband unit and the wireless unit. If the first service is transmitted, the baseband unit determines whether interruption of the transmission of the first service is permitted based on the service information of the first service.

[0138] When the first service is not transmitted, or when the first service is transmitted but the baseband unit allows the interruption of the transmission of the first service, the baseband unit uses all radio frequency channels on the radio unit as the first radio frequency channel, determines the start time of the first time resource to obtain the first time resource, and the duration of the first time resource is equal to the duration of the second time resource. The baseband unit determines the start position of the first frequency resource to obtain the first frequency resource, and the resource size of the first frequency resource is equal to the resource size of the second frequency resource. In this way, the first radio frequency channel, the first time resource, and the first frequency resource included in the first resource are obtained. When the first service is transmitted but the baseband unit does not allow the interruption of the transmission of the first service, it indicates that the baseband unit does not allow the first service to be in a dormant state.

[0139] In example 3, the first radio frequency channel is all radio frequency channels on the wireless unit, the resource size of the first frequency resource is the same as the resource size of the second frequency resource, and the duration of the first time resource is the same as the duration of the second time resource, so the first information includes a start time of the first time resource and a start position of the first frequency resource. The first information may not include or may include other content, such as a channel identifier of the first radio frequency channel, a duration of the first time resource, and / or a resource size of the first frequency resource.

[0140] Example 4: The second information includes a channel identifier of the first radio frequency channel.

[0141] In example 4, the baseband unit determines whether a first service is currently transmitted, and the first service is a service using a first radio frequency channel. If the first service is transmitted, the baseband unit determines whether interruption of the transmission of the first service is permitted based on the service information of the first service. If the first service is not transmitted, or if the first service is transmitted but the baseband unit permits interruption of the transmission of the first service, the baseband unit allocates a first time resource and a first frequency resource. In this way, the first radio frequency channel, the first time resource, and the first frequency resource included in the first resource are obtained.

[0142] In some embodiments, the operation of the baseband unit allocating the first time resource is as follows: the baseband unit determines an interval of a target duration, where the target duration is an interval of a maximum duration in the duration required by the wireless unit to process all tasks, and the baseband unit allocates the first time resource, where the duration of the first time resource is equal to the target duration.

[0143] In some embodiments, the operation of the baseband unit allocating the first frequency resource is as follows: the baseband unit determines a target resource size, where the target resource size is a maximum resource size among the resource sizes required by the wireless unit to process all tasks; and the baseband unit allocates the first frequency resource, where the resource size of the first frequency resource is equal to the maximum resource size; or the baseband unit allocates at least one frequency, where the total frequency resource size of the at least one frequency is equal to the target resource size; and the baseband unit uses the at least one frequency as the first frequency resource.

[0144] In example 4, since the first radio frequency channel in the first resource is the same as the first radio frequency channel in the second resource, the first information includes a start time of the first time resource, a duration of the first time resource, and at least one frequency identifier in the first frequency resource, or the first information includes a start time of the first time resource, a duration of the first time resource, a start position of the first frequency resource, and a resource size of the first frequency resource. The first information may not include a channel identifier of the first radio frequency channel, or may include a channel identifier of the first radio frequency channel.

[0145] In addition to the four examples (Example 1 to Example 4) listed above, there are examples of specific content of the second information, but these are not listed one by one in this specification.

[0146] Case 3: The service outage request includes a task identifier of the first component processing task. In case 3, after receiving the service outage request, the baseband unit determines a first resource based on the task identifier of the first component processing task.

[0147] In some embodiments, the baseband unit obtains corresponding information from a correspondence between the task identifier and the second information based on a task identifier of the first component processing task, and determines the first resource based on the obtained information.

[0148] The obtained information includes one or more portions of content of a channel identifier of the first radio frequency channel, a duration of the second time resource, a starting location of the second frequency resource, a resource size of the second frequency resource, and the like, or alternatively, the obtained information includes one or more portions of content of a channel identifier of the first radio frequency channel, a duration of the second time resource, at least one frequency identifier, and the like.

[0149] For a detailed implementation process of the baseband unit determining the first resource according to the acquired information, please refer to the detailed implementation process of determining the first resource described in Example 1 to Example 4. The details will not be described again in this specification.

[0150] Before performing step 302, the radio unit transmits a task identifier of the first task and the second information to the baseband unit. In this case, the second information may include a channel identifier of the first radio frequency channel, a duration of the second time resource, a resource size of the second frequency resource, and / or the like. The baseband unit receives the task identifier of the first task and the second information, and stores the task identifier of the first task and the second information according to the correspondence between the task identifier of the first task and the second information.

[0151] In some embodiments, when the baseband unit transmits a first service and authorizes the first service to be dormant, the baseband unit stops transmitting the first service using the first frequency resource for a time period corresponding to the first time resource.

[0152] Step 303: The baseband unit sends an out-of-service authorization response to the wireless unit, where the out-of-service authorization response indicates that the first resource is an out-of-service resource.

[0153] In step 303, if the baseband unit determines that the first service is not allowed to be suspended, the baseband unit sends a service suspension refusal response to the wireless unit. After receiving the service suspension refusal response, the wireless unit resends the service suspension request to the baseband unit after a first time point, where the first time point is after a second time point, and the second time point is the actual time point at which the wireless unit receives the service suspension refusal response.

[0154] In some embodiments, the out-of-service refusal response includes a delay duration, and the duration between the first time point and the second time point is equal to or greater than the delay duration. Because the out-of-service refusal response includes the delay duration, the wireless unit resends the out-of-service request after delaying for a time period starting from the second time point at which the out-of-service refusal response was received. The duration of this time period is equal to or greater than the delay duration to prevent the wireless unit from frequently sending out-of-service requests to the baseband unit.

[0155] In some embodiments, the service outage rejection response further includes a rejection reason of the baseband unit. Optionally, the rejection reason includes that a first service currently being transmitted between the baseband unit and the wireless unit cannot be interrupted, or that the first service is a low-latency service, a high-reliability service, a high-priority service, or the like.

[0156] The out-of-service authorization response may include the first information, where the first information indicates the first resource, or the out-of-service authorization response may not include the first information.

[0157] In some embodiments, for case 1 above, the service suspension request may not include the second information, and the service suspension authorization response may not include the first information or may include the first information.

[0158] Regarding the above-mentioned Example 1, when the first resource is the same as the second resource, the first information indicating the first resource is the same as the second information indicating the second resource, and the service suspension permission response may not include the first information or may include the first information. When the first resource is different from the second resource, the first information indicating the first resource is different from the second information indicating the second resource, and the service suspension permission response includes the first information.

[0159] Regarding the above-mentioned Example 2, Example 3, or Example 4, the service outage permission response may not include the first information or may include the first information.

[0160] Step 304: After receiving the out-of-service authorization response, the wireless unit determines a first resource based on the out-of-service authorization response.

[0161] In some embodiments, the out-of-service authorization response does not include the first information, and the wireless unit may determine the first resource in some of the following cases.

[0162] In a first case for the above-mentioned case 1, the service outage request does not include the first information, and the service outage permission response does not include the first information. The process in which the wireless unit determines the first radio frequency channel, the first time resource, and the first frequency resource included in the first resource is shown as follows:

[0163] For the first radio frequency channel, the radio unit uses all or a part of the radio frequency channels on the radio unit as the first radio frequency channel included in the first resource. In the above-mentioned case 1, since the first radio frequency channel determined by the baseband unit includes all the radio frequency channels on the radio unit, the baseband unit transmits a service that does not use the radio frequency channels on the radio unit. Therefore, the radio unit may use all or a part of the radio frequency channels on the radio unit as the first radio frequency channel included in the first resource.

[0164] For the first time resource, the wireless unit determines a start time of the first time resource based on a third point in time, where the third point in time is an actual receiving point in time at which the wireless unit receives the out-of-service authorization response, and the wireless unit determines the first time resource based on a duration required for performing the first task and the start time, where the duration of the first time resource is equal to the duration required for performing the first task.

[0165] In some embodiments, the wireless unit determines the third point in time as the start time of the first time resource, or the wireless unit adds a specified duration to the third point in time to obtain the start time of the first time resource.

For the first time resource, the wireless unit uses the duration of the second time resource as the duration of the first time resource and determines the first time resource based on the start time and duration of the first time resource.

[0175] For the first frequency resource, the wireless unit uses the resource size of the second frequency resource as the resource size of the first frequency resource and determines the first frequency resource based on a starting position and a resource size of the first frequency resource, or the wireless unit determines the at least one frequency of the first frequency resource based on an identifier of the at least one frequency, the identifier being included in the first information.

[0176] If the first information does not include a start time of the first time resource, the wireless unit uses the requested second time resource as the first time resource.If the first information does not include a start time of the first frequency resource or at least one frequency identifier of the first frequency resource, the wireless unit uses the requested second frequency resource as the first frequency resource.

[0177] In a sixth aspect, for the above-mentioned Example 2, the second information in the service outage request includes a channel identifier of the first radio frequency channel, a duration of the second time resource, and a resource size of the second frequency resource, and the first information in the service outage permission response includes a start time of the first time resource and a start position of the first frequency resource. The process of the wireless unit determining the first radio frequency channel, the first time resource, and the first frequency resource included in the first resource is shown as follows:

[0178] For the first radio frequency channel, the radio unit uses the first radio frequency channel included in the requested second resource as the first radio frequency channel of the first resource. For the first time resource, the radio unit uses the duration of the second time resource as the duration of the first time resource and determines the first time resource based on the start time and duration of the first time resource. For the first frequency resource, the radio unit uses the resource size of the second frequency resource as the resource size of the first frequency resource and determines the first frequency resource based on the start location and resource size of the first frequency resource.

[0179] In a seventh aspect, for the above-mentioned Example 3, the second information in the service outage request includes a duration of the second time resource and a resource size of the second frequency resource, and the first information in the service outage permission response includes a start time of the first time resource and a start position of the first frequency resource. The process of the wireless unit determining the first radio frequency channel, the first time resource, and the first frequency resource included in the first resource is shown as follows:

[0180] For the first radio frequency channel, the radio unit uses all or a portion of the radio frequency channel on the radio unit as the first radio frequency channel included in the first resource.For the first time resource, the radio unit uses the duration of the second time resource as the duration of the first time resource and determines the first time resource based on the start time and duration of the first time resource.For the first frequency resource, the radio unit uses the resource size of the second frequency resource as the resource size of the first frequency resource and determines the first frequency resource based on the start location and resource size of the first frequency resource.

[0181] In an eighth aspect, for the above-mentioned Example 4, the second information in the service outage request includes a channel identifier of the first radio frequency channel, and the first information in the service outage permission response includes a start time of the first time resource, a duration of the first time resource, and at least one frequency identifier in the first frequency resource, or the first information includes a start time of the first time resource, a duration of the first time resource, a start position of the first frequency resource, and a resource size of the first frequency resource. A process in which the wireless unit determines the first radio frequency channel, the first time resource, and the first frequency resource included in the first resource is shown as follows:

[0182] For the first radio frequency channel, the radio unit uses the first radio frequency channel included in the requested second resource as the first radio frequency channel of the first resource. For the first time resource, the radio unit determines the first time resource based on a start time and a duration of the first time resource included in the first information. For the first frequency resource, the radio unit determines the first frequency resource based on a start position and a resource size of the first frequency resource included in the first information, or determines the first frequency resource based on at least one frequency identifier of the first frequency resource included in the first information.

[0183] In some embodiments, after determining the first resource, the wireless unit performs the first task using the first resource.

[0184] For example, a first task is a task for calibrating a radio frequency channel of a radio unit, the first radio frequency channel including a transmit radio frequency channel and a receive radio frequency channel. The radio unit activates a loopback unit connecting the transmit radio frequency channel and the receive radio frequency channel and transmits a specified calibration sequence on the transmit radio frequency channel. The loopback unit couples the signal transmitted on the transmit radio frequency channel to the receive radio frequency channel. The radio unit detects the amplitude, delay, and phase of the signal on the receive radio frequency channel and calibrates the transmit radio frequency channel and the receive radio frequency channel included in the first radio frequency channel based on the detected amplitude, delay, and phase and the amplitude and phase of the calibration sequence.

[0185] As another example, the first task is a task for detecting a phase shifter of a radio unit, where a transmit radio frequency channel and a receive radio frequency channel included in a first radio frequency channel are connected to the phase shifter, and a detection unit is present between the phase shifter and the antenna. The radio unit activates the detection unit, sets a phase deviation amplitude of the phase shifter relative to a signal to a specified amplitude, and transmits a specified first detection sequence on the transmit radio frequency channel. The phase shifter receives the first detection sequence from the transmit radio frequency channel, modulates the phase of the first detection sequence to obtain a second detection sequence, and transmits the second detection sequence to the antenna. The detection unit detects the phase of the second detection sequence transmitted to the antenna. If the phase difference between the phase of the first detection sequence and the phase of the second detection sequence is equal to the specified amplitude, the radio unit determines that the phase shifter is normal. If the phase difference between the phase of the first detection sequence and the phase of the second detection sequence is not equal to the specified amplitude, the radio unit determines that the phase shifter is faulty.

[0186] The first task may alternatively be another task, which is not enumerated here one by one.

[0187] In this embodiment of the present application, the wireless unit sends a service suspension request to the baseband unit. The wireless unit receives a service suspension permission response sent by the baseband unit, where the service suspension permission response indicates that the first resource is a suspended resource. After the wireless unit receives the service suspension permission response, both the baseband unit and the wireless unit recognize that the first resource is a suspended resource. The baseband unit may stop transmitting a first service using the first resource, where the first service is a service of the wireless unit, and the wireless unit may use the first resource to autonomously perform a first task. In this way, when the wireless unit uses the first resource to autonomously perform the first task, interference to the first service is avoided, and the performance of the first service is avoided from being affected, for example, an increase in bit errors and retransmissions of the first service are avoided, and the performance of the first service is avoided from being affected, and a deterioration of key performance indicator (KPI) indications is avoided.
