Description

[Technical field]

[0001] The present application relates to the field of communication technologies, and more particularly to information transmission methods and communication devices. [Background technology]

[0002] This application claims priority to Chinese Patent Application No. 202111627373.8, entitled “INFORMATION TRANSMISSION METHOD AND COMMUNICATION APPARATUS,” filed with the China National Intellectual Property Office on December 28, 2021, which is incorporated herein by reference in its entirety.

[0003] When the network controller schedules and manages resources, some resources, for example, some time domain resources and / or frequency domain resources, are idle or some resources do not carry data. However, even if some resources are idle, the radio frequency device still generates corresponding static loss. With increasing requirements for energy saving and environmental protection, currently, when the radio frequency device receives downlink data from the network controller, the radio frequency device may implement symbol power saving by determining in real time whether a symbol carries data. In this way, when some time domain resources do not carry data, the loss of the communication system can be reduced through symbol power saving. However, when the period of the symbol becomes shorter, the chip in the radio frequency device needs to have high symbol level detection ability to determine in real time whether a symbol carries data. This brings challenges to the ability of the chip in the radio frequency device and even causes power saving errors. In addition, when the radio frequency device receives uplink data (which is an analog radio frequency signal) from the terminal device, the radio frequency device cannot determine in real time whether a symbol carries data when processing the uplink data. Therefore, in this manner, the losses of the communication system cannot be reduced when the uplink data is processed.

[0004] Therefore, an information transmission method and a communication device are urgently needed to effectively reduce the loss in the communication system. Summary of the Invention

[0005] The present application provides an information transmission method and a communication device, which can effectively reduce the loss in a communication system.

[0006] According to a first aspect, an information transmission method is provided. The method can be implemented by a radio frequency device or a chip in the radio frequency device. The method includes: the radio frequency device receives indication information from a network controller, the indication information indicating a usage status of a first resource, the usage status being whether the first module carries data on the first resource; and when the usage status is that the first module does not carry data on the first resource, the radio frequency device turns off the first module based on the usage status.

[0007] Therefore, in the present application, the network control device may send indication information indicating the usage status of the first resource to the radio frequency device. When the first module does not carry data on the first resource, the radio frequency device may turn off the first module, thereby effectively reducing the loss of the communication system.

[0008] With regard to the first aspect, in some implementations of the first aspect, the method further includes the first resource including a first time resource, and when the usage situation is that the first module does not carry data on the first resource, the radio frequency device turning off the first module based on the usage situation includes the radio frequency device turning off the first module at a first moment corresponding to the first time resource when the usage situation is that the first module does not carry data in the first time resource.

[0009] Therefore, in the present application, the network control device may instruct the radio frequency device to turn off the first module at a first instant corresponding to a first time resource, to improve the flexibility of the turn-off control.

[0010] With regard to the first aspect, in some implementations of the first aspect, the method further includes the radio frequency device receiving first information from the network controller, where the first information indicates that the first module does not carry uplink data in the first time resource and / or the first information indicates that the first module does not carry downlink data in the first time resource. Turning off the first module at the first time instant corresponding to the first time resource includes the radio frequency device turning off the first module configured to process the uplink data at the first time instant corresponding to the first time resource and / or the radio frequency device turning off the first module configured to process the downlink data at the first time instant corresponding to the first time resource.

[0011] It should be understood that the first module may be configured to process uplink data alone, or the first module may be configured to process downlink data alone, or the first module may be configured to process uplink data and downlink data. When the first information indicates that the first module does not carry uplink data in the first time resource, the radio frequency device may turn off the first module configured to process uplink data alone at the first moment. When the first information indicates that the first module does not carry downlink data in the first time resource, the radio frequency device may turn off the first module configured to process downlink data alone at the first moment. When the first information indicates that the first module does not carry uplink data or downlink data in the first time resource, the radio frequency device may turn off the first module configured to process downlink data alone, the first module configured to process downlink data alone, and the first module configured to process uplink data and downlink data at the first moment.

[0012] Therefore, in the present application, the network control device may inform the radio frequency device of modules that are configured to process uplink data and should be turned off, modules that are configured to process downlink data and should be turned off, or modules that are configured to process uplink data and downlink data and should be turned off, so that the radio frequency device can turn off modules that do not carry data, improving the flexibility of the turn-off control and further effectively reducing the loss of the communication system.

[0013] With respect to the first aspect, in some implementations of the first aspect, the method further includes the radio frequency device receiving second information from the network controller, the second information indicating that the first module corresponding to the radio frequency channel does not carry data in the first time resource. The radio frequency device turning off the first module at the first moment corresponding to the first time resource includes the radio frequency device turning off the first module corresponding to the radio frequency channel at the first moment.

[0014] Therefore, in the present application, the network control device may also send second information to the radio frequency device to inform that the first module does not carry data on a certain radio frequency channel or multiple certain radio frequency channels, so that the radio frequency device can turn off the first module corresponding to the radio frequency channel that does not carry data, which improves the turn-off flexibility and further effectively reduces the loss of the communication system.

[0015] With regard to the first aspect, in some implementations of the first aspect, the method further includes the radio frequency device receiving first information and second information from the network controller, where the first information indicates that the first module does not carry uplink data in the first time resource, and / or the first information indicates that the first module does not carry downlink data in the first time resource, and the second information indicates that the first module corresponding to the radio frequency channel does not carry data in the first time resource. Turning off the first module at the first moment corresponding to the first time resource includes the radio frequency device turning off the first module configured to process the uplink data and corresponding to the radio frequency channel at the first moment, and / or the radio frequency device turning off the first module configured to process the downlink data and corresponding to the radio frequency channel at the first moment.

[0016] Therefore, in the present application, the network controller may inform the radio frequency device of a certain radio frequency channel or a plurality of certain radio frequency channels on which the radio frequency device will turn off a module configured to process uplink data, a module configured to process downlink data, or a module configured to process uplink data and downlink data, so that the radio frequency device may turn off modules that do not carry data. This improves the flexibility of the turn-off control and further effectively reduces the loss of the communication system.

[0017] With regard to the first aspect, in some implementations of the first aspect, the indication information is status indication information, where the status indication information indicates whether the first module carries data on the first resource, and / or the indication information is turn-off indication information, where the turn-off indication information indicates whether the radio frequency device turns off the first module.

[0018] Therefore, in the present application, the network control device may indicate to the radio frequency device to turn off the first module in an explicit indication manner, and may also indicate to the radio frequency device to turn off the first module in an implicit indication manner, which improves the flexibility of the communication system.

[0019] Regarding the first aspect, in some implementations of the first aspect, the first time resource is any one of the following resources: a subframe resource, a symbol resource, and a slot resource.

[0020] Therefore, in this application, the network controller may indicate to the radio frequency unit to turn off the first module with a granularity of a subframe, a symbol, or a slot to improve the flexibility of the communication system.

[0021] Regarding the first aspect, in some implementations of the first aspect, the first module includes at least one of the following modules: a baseband processing module, an intermediate frequency processing module, a radio frequency processing module, and a power module.

[0024] Therefore, in the present application, the network controller may send indication information indicating the usage status of the first resource to the radio frequency device, and the radio frequency device adjusts the power of the radio frequency device based on the usage status, so that the power level of the radio frequency device can match the status of the data carried on the first resource, thereby reducing the loss of the communication system.

[0025] Regarding the second aspect, in a possible implementation, the first resource is a first frequency domain resource, and the status of the data carried on the first resource includes whether the first frequency domain resource carries data, or a utilization rate of the first frequency domain resource, or a bandwidth of the frequency domain resource of the first frequency domain resource on which data is carried, or a bandwidth of the frequency domain resource of the first frequency domain resource on which data is not carried, or an occupancy change amount of the bandwidth of the data carried on the first frequency domain resource.

[0026] Optionally, the status of the data carried on the first resource indicates a bandwidth of the data carried on the first frequency domain resource.

[0027] In the present application, the network controller may use different parameter quantities, such as whether data is carried, utilization rate, bandwidth, and occupancy change quantity, to indicate the status of data carried on the first frequency domain resource, and the radio frequency device adjusts the power of the radio frequency device based on the received parameter quantities to improve the flexibility of information transmission in the communication system.

[0029] It should be understood that when the third information indicates that the usage situation is a state in which the first resource carries uplink data, the radio frequency device may adjust the power used to process the uplink data based on the usage situation, when the third information indicates that the usage situation is a state in which the first resource carries downlink data, the radio frequency device may adjust the power used to process the downlink data based on the usage situation, and when the third information indicates that the usage situation is a state in which the first resource carries uplink data and downlink data, the radio frequency device may adjust the power used to process the uplink data and downlink data based on the usage situation.

[0030] Therefore, in the present application, the network controller may flexibly indicate a specific power to be adjusted by the radio frequency device based on usage conditions, so as to improve the flexibility of information transmission in the communication system.

[0031] With regard to the second aspect, in a possible implementation, the radio frequency device adjusting the power of the radio frequency device based on the usage status includes the radio frequency device adjusting the power of at least one of the following modules in the radio frequency device based on the usage status: a baseband processing module, an intermediate frequency processing module, a radio frequency processing module, and a power module.

[0032] Alternatively, adjusting the power of the radio frequency device may be adjusting the power of at least one of the components in the radio frequency device, i.e., all or some of the components in the baseband processing module, all or some of the components in the intermediate frequency processing module, all or some of the components in the radio frequency processing module, and all or some of the components in the power module.

[0033] With respect to the second aspect, in a possible implementation, the radio frequency device adjusting a power of the radio frequency device based on usage includes the radio frequency device determining a power of the radio frequency device based on a bandwidth of data carried on the first frequency domain resource.

[0034] The radio frequency device adjusts a power of the radio frequency device such that the power of the radio frequency device corresponds to a bandwidth of data carried on the first frequency domain resource.

[0035] It should be appreciated that the network controller may explicitly inform the radio frequency device of the bandwidth of the data carried on the first frequency domain resource based on parameters such as utilization rate, occupancy change, and bandwidth of the data not carried, or may implicitly inform the radio frequency device of the bandwidth of the data carried on the first frequency domain resource.

[0036] Therefore, in the present application, the power of the radio frequency device may be adjusted based on the bandwidth of the data carried on the first frequency domain resource to improve power adjustment reliability.

[0106] The following describes the technical solutions in this application with reference to the accompanying drawings.

[0107] The technical solutions in the embodiments of the present application may be applied to various communication systems, such as long term evolution (LTE) systems, frequency division duplex (FDD) systems, time division duplex (TDD) systems, universal mobile telecommunications system (UMTS), worldwide interoperability for microwave access (WiMAX) communication systems, fifth generation (5G) systems, new radio (NR) systems, sixth generation (6G) systems, or future communication systems. The 5G mobile communication system in the present application includes a non-standalone (NSA) 5G mobile communication system or a standalone (SA) 5G mobile communication system. The communication system may alternatively be a public land mobile network (PLMN), a device-to-device (D2D) communication system, a machine to machine (M2M) communication system, an Internet of things (IoT) communication system, a vehicle-to-everything (V2X) communication system, an unmanned aerial vehicle (UAV) communication system, or another communication system.

[0108] In addition, the network architecture and service scenarios described in the embodiments of the present application are intended to more clearly explain the technical solutions in the embodiments of the present application, and do not constitute limitations on the technical solutions provided in the embodiments of the present application. With the development of network architecture and the emergence of new service scenarios, those skilled in the art may understand that the technical solutions provided in the embodiments of the present application can also be applied to similar technical problems.

[0109] In order to facilitate understanding of the embodiments of the present application, an application scenario of the embodiments of the present application will first be described in detail with reference to FIG.

[0110] 1 is a diagram of the structure of a communication system to which an embodiment of the present application can be applied. First, an apparatus that can be used in the communication system is described.

[0111] 1. A radio equipment controller (REC) 110 may be configured to process digital baseband signals and control and manage radio equipment. In some communication systems, the REC 110 may be a baseband unit (BBU) and mainly implements the function of processing baseband signals. In future or other communication systems, the REC 110 may have a different name or a different function. This is not particularly limited in this application.

[0112] In this application, the REC 110 may include a scheduler. The scheduler may allocate time-frequency resources to uplink data or downlink data, and transmit the data using the allocated time-frequency resources.

[0113] 2. Radio frequency equipment (RE) 120 may be configured to implement functions such as intermediate frequency processing, radio frequency processing, and signal duplexing. In some communication systems, RE 120 may be a remote radio unit (RRU) or an active antenna unit (AAU). In future or other communication systems, RE 120 may have another name, which is not particularly limited in this application.

[0114] Furthermore, the communication interface between the REC 110 and the RE 120 may be referred to as a fronthaul interface. The fronthaul interface may be a common public radio interface (CPRI), an enhanced CPRI (eCPRI) interface, or another interface to be defined in the future, configured to connect the BBU 110 and the RRU 120, which is not particularly limited in this application.

[0115] When different fronthaul interfaces are used between the REC and the RE, the REC and the RE may have different function division schemes.

[0116] 2 is a diagram of different communication interfaces to which the embodiments of the present application are applicable. The CPRI interface generally adopts division scheme 1. In the RE downlink direction, the RE has the functions of analog beamforming and digital-to-analog conversion. In the RE uplink direction, the RE has the functions of analog beamforming and analog-to-digital conversion. In the REC downlink direction, the REC has the functions of coding, rate matching, scrambling, modulation, layer mapping, pre-coding, resource mapping, digital beamforming, as well as inverse fast Fourier transformation (IFFT) and cyclic prefix addition. In the uplink direction of the REC, the REC has the functions of decoding and rate de-matching, de-scrambling, demodulation, channel estimation / equalization, inverse discrete Fourier transform (IDFT), resource de-mapping, digital beamforming, as well as fast Fourier transform (FFT) and cyclic prefix removal.

[0117] The eCPRI interface may adopt division scheme 2. Compared with scheme 1, the functions of IFFT and cyclic prefix addition in the downlink direction are moved from the REC to the RE. Similarly, the functions of FFT and cyclic prefix removal in the uplink direction are moved from the REC to the RE.

[0118] It should be understood that the eCPRI interface may use a different division scheme, or that other interfaces may use a different division scheme. The embodiments of the present application are applicable to devices or communication systems with various division schemes, which are not particularly limited in the present application.

[0119] It should be understood that the above functions may have independent devices or chips, or may be integrated into one or more devices or chips. For example, in the RE, the functions responsible for baseband processing (e.g., FFT and IFFT) may be integrated into a baseband processing module, the functions responsible for intermediate frequency processing (e.g., digital-to-analog conversion and analog-to-digital conversion) may be integrated into an intermediate frequency processing module, and the functions responsible for converting radio signals into specific radio signal waveforms may be integrated into a radio frequency processing module. The radio frequency processing module may include a radio frequency chip, which may include components such as a power amplifier (PA), a radio on chip (ROC), a low noise amplifier (LNA), and a down converter. In addition, the RE and the REC may further include another functional module. For example, the RE may further include a power module responsible for supplying power. The power module may be deployed alone to supply power to all or some of the other modules, or may be deployed within each module to supply power to each module. This is not explicitly limited in the present application.

[0120] Furthermore, when the RE includes multiple radio frequency channels, each radio frequency channel may have an independent intermediate frequency processing module, a radio frequency processing module, and a power module. Additionally, each module may further include a module configured to process uplink data and a module configured to process downlink data. For example, in the baseband processing module, an FFT module is configured to process uplink data, and an IFFT module is configured to process downlink data.

[0121] When a network controller schedules and manages resources, some resources do not carry data, but the radio frequency device still generates corresponding static loss. At present, when the radio frequency device receives downlink data from the network controller, the radio frequency device can implement symbol power saving by determining in real time whether a symbol carries data, so as to reduce the loss of the communication system. However, the requirements for energy saving and environmental protection still cannot be met. The present application provides an information transmission method for effectively reducing the loss of the communication system.

[0122] FIG. 3 is a schematic flowchart of an information transmitting method 300 according to an embodiment of the present application.

[0123] S301: A network control device determines indication information, where the indication information indicates a usage status of a first resource.

[0124] The usage status is whether the first module carries data on the first resource.

[0125] The first module is all or part of the modules or all or part of the components described in the above radio frequency device. The radio frequency device may be the RE 120 shown in FIG. 1, and the network control device may be the REC 110 shown in FIG. 1.

[0126] Optionally, the first module includes at least one of the following modules: a baseband processing module, an intermediate frequency processing module, a radio frequency processing module, and a power module.

[0127] Alternatively, the first module may include at least one of the following components: all or a portion of the components in a baseband processing module, all or a portion of the components in an intermediate frequency processing module, all or a portion of the components in a radio frequency processing module, and all or a portion of the components in a power module.

[0128] For example, the first module may include, but is not limited to, a PA, an analog-to-digital converter or a digital-to-analog converter, a ROC, an LNA, a downconverter, etc. The PA, the digital-to-analog converter, and the ROC may be configured to process downlink data, and the LNA, the downconverter, and the analog-to-digital converter may be configured to process uplink data.

[0129] It should be understood that the first module in the present application may further include other apparatuses and devices that can be configured to process data, which is not particularly limited in the present application.

[0130] It will be understood that when the first module does not carry data on the first resource, the first resource is idle and the first module does not carry data on the first resource. The first module does not carry data on the first resource will be understood as the first resource not carrying service data and / or not carrying control signaling. It will be understood that when the first module carries data on the first resource, the first resource is busy and the first resource carries service data and / or control signaling.

[0131] In a possible implementation, the first resource includes a first time resource.

[0132] The first time resource may be a subframe resource, a slot resource, or a symbol resource.

[0133] For example, a communication system may implement scheduling by using a subframe, a slot, or a symbol as a time unit. The first time resource may be one or more subframes, one or more slots, or one or more symbols. The indication information may be represented by one bit. For example, when the first module does not carry data on the symbol, the bit is set to "0", and when the first module carries data on the symbol, the bit is set to "1".

[0134] It should be understood that the indication information may be status indication information, where the status indication information indicates whether the first module carries data on the first resource, and / or the indication information is turn-off indication information, where the turn-off indication information indicates whether the radio frequency device turns off the first module. Furthermore, the network control device may indicate the radio frequency device to turn off the first module in an explicit indication manner, or may also indicate the radio frequency device to turn off the first module in an implicit indication manner. This improves the flexibility of the communication system.

[0135] In this embodiment of the present application, the network control device may further determine that the first module configured to process uplink data does not carry data or that the first module configured to process downlink data does not carry data. In a possible implementation, the radio frequency device determines first information. The first information indicates that the first module does not carry uplink data in the first time resource, and / or the first information indicates that the first module does not carry downlink data in the first time resource.

[0136] For example, the first information may be a field including at least one bit. It is used as an example that the first information has one bit. For example, when the bit is "0", the first information indicates that the first module does not carry uplink data in the first time resource, and when the bit is "1", the first information indicates that the first module does not carry downlink data in the first time resource. Alternatively, it is used as an example that the first information has two bits. When the bit is "00", the first information indicates that the first module does not carry uplink data or downlink data in the first time resource. When the bit is "10", the first information indicates that the first module carries uplink data but does not carry downlink data in the first time resource. When the bit is "01", the first information indicates that the first module does not carry uplink data but carries downlink data in the first time resource. When the bit is '11', the first information indicates that the first module carries both uplink data and downlink data in the first time resource.

[0137] Therefore, in the present application, the network control device may determine that a module configured to process uplink data or a module configured to process downlink data does not carry data, so that the radio frequency device can turn off the module that does not carry data, thereby improving the flexibility of the turn-off control and further effectively reducing the loss of the communication system.

[0138] Optionally, when the usage situation is that the first module carries data in the second time resource, the first information further indicates the first module to carry uplink data in the second time resource, and / or the first information further indicates the first module to carry downlink data on the second resource. Correspondingly, the radio frequency device may turn on the first module configured to process the uplink data at a second moment corresponding to the second time resource, and / or the radio frequency device may turn on the first module configured to process the downlink data at a second moment corresponding to the second time resource. For the sake of brevity, details are not described here.

[0139] In this embodiment of the present application, the network control device may further determine a specific radio frequency channel corresponding to a first module that does not carry data, or a specific radio frequency channel corresponding to a first module that does not carry data. In a possible implementation, the radio frequency device determines second information. The second information indicates that the first module corresponding to the radio frequency channel does not carry data in the first time resource.

[0140] For example, the second information may be an identification information of a radio frequency channel corresponding to the first module, or the second information may be an identification information of a cell corresponding to the first module. The identification information of the cell may be used to index the radio frequency channel corresponding to the first module. Furthermore, the second information may include both the identification information of the radio frequency channel corresponding to the first module and the identification information of the cell. This is not particularly limited in the present application.

[0141] The second information and the indication information may be carried in two fields, respectively, or the second information and the indication information may be carried in one field, for example, an array-structured field may be used to describe both the second information and the indication information.

[0142] By way of example and not limitation, the network controller may further send information to the radio frequency device indicating a quantity of radio frequency channels of the radio frequency device. In the following, an example is used in which the quantity information indicates that the radio frequency device includes P radio frequency channels and the indication information indicates whether the first module carries data in each of the N symbols, where P and N are both positive integers.

[0143] In a first possible implementation, P arrays are defined, each of which includes at least N bits. The P arrays correspond one-to-one with the P radio frequency channels, and the N bits correspond one-to-one with the N symbols. For example, when the jth bit among the N bits of the ith array among the P arrays is "0", the radio frequency device may turn off a first module corresponding to the ith radio frequency channel among the P radio frequency channels at a first instant corresponding to the jth symbol among the N symbols, where i=1,...,P, j=1,...,N.

[0144] In a second possible implementation, N arrays are defined, each of which includes at least P bits. The N arrays correspond one-to-one with the N symbols, and the P bits correspond one-to-one with the P radio frequency channels. For example, when the sth bit among the P bits of the kth array among the N arrays is "0", the radio frequency device may turn off a first module corresponding to the sth radio frequency channel among the P radio frequency channels at a first instant corresponding to the kth symbol among the N symbols, where s=1,...,P, k=1,...,N.

[0145] It should be understood that the above describes in the form of an array that the first module does not carry data on a time resource or resources and a particular radio frequency channel or channels. The position of the bit in the array is used to describe the time resource and the radio frequency channel, and the bit is set to "0" to indicate that the first module does not carry data. Similarly, the bit is set to "1" to indicate that the first module carries data. The above is merely an example for explanation. The present application may further include another definition manner that can be described.

[0146] The network control device may inform the first module that the first module does not carry data on a certain radio frequency channel or a plurality of certain radio frequency channels by determining the second information, so that the radio frequency device turns off the first module corresponding to the radio frequency channel that does not carry data, which improves turn-off flexibility and further effectively reduces the loss of the communication system.

[0147] S302: The network control device sends indication information to the radio frequency device, and correspondingly, the radio frequency device receives the indication information sent by the network control device.

[0148] The network control device may send the indication information to the radio frequency device individually, or may send a first message (e.g., a real-time control message) including the indication information to the radio frequency device, which is not particularly limited in this application.

[0149] For example, when the first time resource is a subframe resource, the first message may include a subframe number of the subframe resource, for example, the subframe number is a subframe number in a radio frame, so that the radio frequency device can know the specific subframe resource on which the first module does not carry data or carries data based on the indication information.

[0150] In another example, when the first time resource is a slot resource, the first message may include a slot number of the slot resource. For example, the slot number may be a slot number in a subframe, so that the radio frequency device can know the specific slot resource on which the first module does not carry data or carries data based on the indication information.

[0151] It should be understood that when the network controller separately sends the indication information to the radio frequency device, the network controller may also separately send the subframe number and the slot number to the radio frequency device. For the sake of brevity, details are not described here.

[0152] If the network control device further determines the first information, the method 300 may further include:

[0153] The network controller sends the first information to the radio frequency device, and in response, the radio frequency device receives the first information from the network controller.

[0154] The network control device may send the first information to the radio frequency device separately, or may send a first message including the first information to the radio frequency device, which is not particularly limited in this application.

[0155] When the network controller further determines the second information, the method 300 may further include:

[0156] The network controller sends the second information to the radio frequency device, and in response, the radio frequency device receives the second information from the network controller.

[0157] The network control device may send the second information to the radio frequency device separately, or may send the first message including the second information to the radio frequency device, which is not particularly limited in this application.

[0158] S303: When the usage status is that the first module does not carry data on the first resource, based on the usage status, the radio frequency device turns off the first module.

[0159] When the first resource includes a first time resource, the radio frequency device may learn, based on usage, that the first module does not carry data in the first time resource.

[0160] The radio frequency device may turn off the first module at a first instant in time corresponding to the first time resource.

[0161] Alternatively, the radio frequency device may allow the first module to be in a turned-off state for a time corresponding to the first time resource.

[0162] The first instant is an instant in the first time resource. For example, the first instant may be an early instant in the first time resource.

[0163] When the first information indicates that the first module does not carry uplink data in the first time resource, if the network control device further sends the first information to the radio frequency device, the radio frequency device turns off the first module configured to process the uplink data at the first moment; When the first information indicates that the first module does not carry downlink data in the first time resource, the radio frequency device turns off the first module configured to process the downlink data at the first moment; When the first information indicates that the first module carries neither uplink data nor downlink data in the first time resource, the radio frequency device turns off the first module configured to process the uplink data and / or the first module configured to process the downlink data at the first moment in time.

[0164] It should be understood that the radio frequency device turning off the first module configured to process downlink data at the first moment may refer to turning off all or a part of modules configured to process downlink data in the radio frequency device. Correspondingly, the radio frequency device turning off the first module configured to process uplink data at the first moment may refer to turning off all or a part of modules configured to process uplink data in the radio frequency device. For example, the first module configured to process downlink data may include, but is not limited to, a PA, a digital-to-analog converter, and a ROC, and the first module configured to process uplink data may include, but is not limited to, an LNA, a downconverter, and an analog-to-digital converter.

[0165] The network control device further sends second information to the radio frequency device, where if the second information indicates that the first module corresponding to the radio frequency channel does not carry data in the first time resource, the radio frequency device turns off the first module corresponding to the radio frequency channel.

[0166] If the network control device further sends the first information and the second information to the radio frequency device when the first information indicates that the first module does not carry uplink data in the first time resource, the radio frequency device turns off, at the first moment, the first module configured to process uplink data and corresponding to the radio frequency channel indicated by the second information, when the first information indicates that the first module does not carry downlink data in the first time resource, the radio frequency device turns off, at the first moment, the first module configured to process downlink data and corresponding to the radio frequency channel indicated by the second information, and when the first information indicates that the first module does not carry uplink data and downlink data in the first time resource, the radio frequency device turns off, at the first moment, the first module configured to process uplink data and downlink data and corresponding to the radio frequency channel indicated by the second information.

[0167] For example, the network controller sends a subframe numbered 1 to the radio frequency device, where the slot number 5 indicates the fifth slot in the subframe, the first information bit set to 0 indicates downlink, the amount of radio frequency channels is 5, the second information indicates a second radio frequency channel among the five radio frequency channels, and the indication information set to 0 indicates that no data is carried in the slot. In this case, the radio frequency device turns off a first module configured to process downlink data and corresponding to the second radio frequency channel among the five radio frequency channels at an initial moment corresponding to the fifth slot in the first subframe in the radio frame.

[0168] In another example, the network controller sends a subframe numbered 1 to the radio frequency device, where the slot number 5 indicates the fifth slot in the subframe, the first information bit is set to 0 to indicate downlink, the amount of radio frequency channels is 5, the second information indicates the second radio frequency channel among the five radio frequency channels, and the indication information set to 10101 indicates that the second and fourth symbols in the slot do not carry data and the first, third and fifth symbols carry data. In this case, the radio frequency device turns off a first module configured to process downlink data and corresponding to the second radio frequency channel among the five radio frequency channels at an initial moment corresponding to the second and fourth symbols in the fifth slot in the first subframe in the radio frame, and correspondingly turns on a first module configured to process downlink data and corresponding to the second radio frequency channel among the five radio frequency channels at an initial moment corresponding to the first, third and fifth symbols in the fifth slot.

[0169] It should be understood that in this embodiment of the present application, the first moment may alternatively be another moment in the first time resource, for example, a certain threshold is ensured when the first time resource is first entered, and a moment after the first time resource is first entered is used as the first moment when the first module needs to be turned off, thereby improving turn-off reliability.

[0170] It should be noted that the time at which the radio frequency device receives the indication information should be earlier than the first instant, or in other words, earlier than the time at which the data is received. The timing advance between the time at which the network controller sends the indication information and the time at which the network controller sends the data is related to the processing delay in parsing the indication information and performing the turn-off by the radio frequency device.

[0171] The radio frequency device may analyze the indication information and turn off the first module at a first time instant. Turning off may refer to powering off the first module, or may refer to causing the first module to enter a hibernation state, or another case in which energy can be saved.

[0172] In addition, the radio frequency device turning off the first module may mean that all or some components in the first module are turned off, which is not particularly limited in this application.

[0173] In a possible manner, the first resource further includes a second time resource. When the usage situation is that the first module does not carry data in the first time resource and the first module carries data in the second time resource, the radio frequency device turns off the first module at a first moment corresponding to the first time resource, and the radio frequency device turns on the first module at a second moment corresponding to the second time resource. Alternatively, the radio frequency device makes the first module in a turn-off state during the time corresponding to the first time resource, and the radio frequency device makes the second module in a turn-on state during the time corresponding to the second time resource.

[0174] The second instant may be an earlier instant within the second time resource or may be an earlier instant than the time corresponding to the second time resource, to ensure that the first module is in a turned-on state when the radio frequency device receives data at a time corresponding to the second time resource.

[0175] For example, when the first resource includes multiple symbol resources, if the communication system implements scheduling by using slots as time units, the first resource is N symbols included in one slot, where N is a positive integer. The indication information may be set to include N bits, where N bits correspond one-to-one with N symbols, where N is a positive integer, and each bit in the N bits may indicate whether the first module carries data on the corresponding symbol. Thus, the radio frequency device may determine, based on the indication information, a specific symbol that is the first time resource that does not carry data and a specific symbol that is the second time resource for carrying data.

[0176] The following description will be made with reference to Fig. 4. Fig. 4 is a diagram of turning off and turning on the first module. As shown in Fig. 4, the indication information includes 10 bits, the 10 bits correspond to 10 symbols, and the bits set to 0 indicate that the first module does not carry data on the symbol, and the bits set to 1 indicate that the first module carries data on the symbol. If the indication information is 1001011000, it may be the radio frequency situation that the first module is turned off in the second, fifth and eighth symbols, and the first module is turned on in the first, fourth and sixth symbols.

[0177] Therefore, in the present application, the network control device may send indication information indicating the usage status of the first resource to the radio frequency device. When the first module does not carry data on the first resource, the radio frequency device may turn off the first module, thereby effectively reducing the loss of the communication system.

[0178] FIG. 5 is a schematic flowchart of an information transmitting method 500 according to an embodiment of the present application.

[0179] S501: A network control device determines indication information.

[0180] The indication information indicates a usage status of the first resource, the usage status being a status of data carried on the first resource.

[0181] Optionally, the first resource may be a first frequency domain resource.

[0182] The status of the data carried on the first resource may be any one or more of the following five cases:

[0183] Case 1: Whether the first frequency domain resource carries data.

[0184] The first frequency domain resource may be a frequency domain resource corresponding to the first time domain resource, such as a frequency domain resource corresponding to one or more slots, one or more subframes, or one or more symbols. For example, the status of data carried on the first resource may be whether data is carried on a frequency domain resource corresponding to a slot.

[0185] Alternatively, the first frequency domain resource may be several frequency bands in the frequency domain resource corresponding to the first time domain resource. For example, the frequency domain resource corresponding to one slot is divided into multiple frequency bands, and the status of the data carried on the first resource may be whether the data is carried in a specific frequency band or multiple specific frequency bands in the multiple frequency bands.

[0186] Case 2: Utilization of the first frequency domain resource.

[0187] The utilization rate of the first frequency domain resource may be a percentage of the bandwidth of the data carried on the first frequency domain resource relative to the total bandwidth of the first frequency domain resource. For example, the first frequency domain resource includes a bandwidth of 100M (million bits per second, i.e., M), where 80M of the bandwidth carries data and 20M of the bandwidth does not carry data. The utilization rate of the first frequency domain resource is 80%. In another example, the first frequency domain resource includes 10 frequency bands, where 8 frequency bands carry data and 2 frequency bands do not carry data. The utilization rate of the first frequency domain resource is 80%.

[0188] Case 3: The bandwidth of a frequency domain resource of a first frequency domain resource over which data is carried.

[0189] For example, the first frequency domain resource includes 10 frequency bands, each frequency band has a bandwidth of 20M, and 8 frequency bands among the 10 frequency bands carry data and 2 frequency bands do not carry data. The indication information may indicate that the frequency domain resource bandwidth of the first frequency domain resource on which the data is carried is 160M, or the indication information may indicate that the frequency domain resource bandwidth of the first frequency domain resource on which the data is carried is the sum of the bandwidths of the 8 frequency bands.

[0190] Case 4: The bandwidth of a frequency domain resource of a first frequency domain resource over which no data is carried.

[0191] For example, the first frequency domain resource includes 10 frequency bands, each frequency band has a bandwidth of 20M, and 8 frequency bands among the 10 frequency bands carry data and 2 frequency bands do not carry data. The indication information may indicate that the bandwidth of the frequency domain resource of the first frequency domain resource on which data is not carried is 40M, or the indication information may indicate that the bandwidth of the frequency domain resource of the first frequency domain resource on which data is not carried is the sum of the bandwidth of the two frequency bands.

[0192] Case 5: A change in the bandwidth occupancy of data carried on a first frequency domain resource.

[0193] The bandwidth occupancy change amount may be a difference between the bandwidth of the data carried on the first frequency domain resource and the bandwidth of the data carried on the second frequency domain resource. The slot or symbol corresponding to the first frequency domain resource is a slot or symbol after the slot or symbol corresponding to the second frequency domain resource. For example, the first frequency domain resource is a frequency domain resource corresponding to the first slot, the second slot is a slot before the first slot, the frequency domain resource carrying data in the frequency domain resource corresponding to the second slot is 60M, and the frequency domain resource carrying data in the first frequency domain resource corresponding to the first slot is 20M. In this case, the bandwidth occupancy change amount of the data carried on the first frequency domain resource may be a reduction of 40M.

[0194] In this embodiment of the present application, the network control device may further determine that the first module configured to process uplink data does not carry data, or the first module configured to process downlink data does not carry data. The following will describe this.

[0195] Optionally, the network control device determines third information, where the third information indicates that the usage situation is that the first resource carries uplink data, and / or the third information indicates that the usage situation is that the first resource carries downlink data.

[0196] The network control device may simultaneously indicate whether multiple frequency domain resources carry uplink data and whether multiple frequency domain resources carry downlink data. For example, the network control device may indicate whether each frequency band in one slot carries uplink data and whether each frequency band carries downlink data. As shown in Table 1, the frequency domain resource corresponding to one slot includes 10 frequency bands, which are frequency band 1 to frequency band 10, respectively, and each frequency band has a bandwidth of 20M. When the indication information corresponding to each frequency band is set to "1", it indicates that the frequency band carries data, and when the indication information corresponding to each frequency band is set to "0", it indicates that the frequency band does not carry data. Thus, as shown in Table 1, in the uplink direction, frequency band 1 and frequency band 8 carry uplink data, and other frequency bands do not carry uplink data, and in the downlink direction, frequency band 1 and frequency band 7 carry downlink data, and other frequency bands do not carry downlink data.

[0197] [Table 1]

[0198] After receiving the message shown in Table 1, the radio frequency device may learn that it needs to process uplink data of a bandwidth of 40M and downlink data of a bandwidth of 40M, and adjust the power of a module configured to process the uplink data, e.g., the FFT, to a power level corresponding to the bandwidth of 40M, and adjust the power of a module configured to process the downlink data, e.g., the IFFT, to a power level corresponding to the bandwidth of 40M.

[0199] S502: The network control device sends indication information to the radio frequency device, and correspondingly, the radio frequency device receives indication information from the network control device.

[0200] The network control device may send the indication information to the radio frequency device individually, or may send a first message (e.g., a real-time control message) including the indication information to the radio frequency device, which is not particularly limited in this application.

[0201] Optionally, the network controller sends, to the radio frequency device, information indicating a first slot resource corresponding to the first frequency domain resource. For example, the network controller may further send, to the radio frequency device, a slot number, a subframe number, or a symbol number corresponding to the first frequency domain resource.

[0202] When the network control device further determines the third information, the method 500 may further include:

[0203] Optionally, the network controller sends the third information to the radio frequency device, and correspondingly, the radio frequency device receives the third information from the network controller.

[0204] The network control device may send the third information to the radio frequency device separately, or may send the first message including the third information to the radio frequency device, which is not particularly limited in this application.

[0205] S503: The radio frequency device adjusts the power of the radio frequency device based on the usage status.

[0206] The radio frequency device may adjust power based on usage so that the data processing capabilities of the radio frequency device match the data that needs to be processed.

[0207] Adjusting the power of the radio frequency device may be adjusting the power of at least one of the following modules in the radio frequency device: a baseband processing module, an intermediate frequency processing module, a radio frequency processing module, and a power module.

[0208] Alternatively, adjusting the power of the radio frequency device may be adjusting the power of at least one of the components in the radio frequency device, i.e., all or some of the components in the baseband processing module, all or some of the components in the intermediate frequency processing module, all or some of the components in the radio frequency processing module, and all or some of the components in the power module.

[0209] It will be appreciated that when the power of the radio frequency device is adjusted to 0 or below a pre-set threshold, all or some of the modules in the radio frequency device will be turned off or all or some of the modules will enter a hibernation state.

[0210] It should be understood that all or some of the modules whose power is adjusted are related to the functionality of the radio frequency device, for example, when a radio frequency device has a module configured to process the bandwidth of a frequency band, and the frequency band does not carry data, the power of the module may be adjusted to 0 or below a pre-set threshold.

[0211] Furthermore, when the third information indicates that the usage status is a status that the first resource carries uplink data, the network control device further sends the third information to the radio frequency device, the radio frequency device adjusts power present in the radio frequency device and used for processing the uplink data based on the usage status; When the third information indicates that the usage status is a status that the first resource carries downlink data, the radio frequency device adjusts power present in the radio frequency device and used for processing the downlink data based on the usage status; When the third information indicates that the usage status is a status in which the first resource carries uplink data and downlink data, the radio frequency device adjusts, based on the usage status, the power present in the radio frequency device and used to process the uplink data and the downlink data.

[0212] It should be understood that adjusting the power used in the radio frequency device to process uplink data may refer to adjusting the power of all or a part of modules in the radio frequency device configured to process uplink data. Correspondingly, adjusting the power used in the radio frequency device to process downlink data may refer to adjusting the power of all or a part of modules in the radio frequency device configured to process downlink data. For example, the power used to process downlink data may include, but is not limited to, the power of an IFFT, and the power used to process uplink data may include, but is not limited to, the power of an FFT.

[0213] The radio frequency device adjusting the power of the radio frequency device based on the usage includes the radio frequency device determining a power of the radio frequency device based on a bandwidth of data carried on a first frequency domain resource, whereby the power of the radio frequency device matches the bandwidth of the data carried on the first resource.

[0214] For example, for case 1 above, if usage indicates that a first frequency domain resource corresponding to a first time resource does not carry data, the radio frequency device may adjust the power of the radio frequency device to zero or below a pre-set threshold.

[0215] In another example, for case 2 above, when the usage status indicates a utilization rate of the first frequency domain resource, the radio frequency device may determine a bandwidth of data carried on the first resource based on the utilization rate, and adjust the power of a corresponding module in the radio frequency device to a power corresponding to the bandwidth based on the correspondence between the bandwidth and the power. The correspondence may be preset based on the hardware characteristics of the radio frequency device.

[0216] In another example, for case 3 above, if the usage indicates a bandwidth of a frequency domain resource of a first frequency domain resource over which data is carried, the radio frequency device may adjust the power of a corresponding module in the radio frequency device to a power corresponding to the bandwidth based on the correspondence between bandwidth and power.

[0217] In another example, for case 4 above, if the usage indicates a frequency domain resource bandwidth of a first frequency domain resource over which data is not carried, the radio frequency device may determine a bandwidth of data carried on the first resource based on the bandwidth of the frequency domain resource over which data is not carried, and based on the correspondence between bandwidth and power, adjust the power of a corresponding module in the radio frequency device to a power corresponding to the bandwidth.

[0218] In another example, for case 5 above, if the usage situation indicates a decrease in the occupancy change of the bandwidth of the first frequency domain resource, the radio frequency device may correspondingly decrease the power of the corresponding module in the radio frequency device. Correspondingly, if the usage situation indicates an increase in the occupancy change of the bandwidth of the first frequency domain resource, the radio frequency device may correspondingly increase the power of the corresponding module in the radio frequency device.

[0219] The above are merely illustrative examples and do not limit the manner of adjusting power in this application.

[0220] Therefore, in the present application, the network controller may send indication information indicating the usage status of the first resource to the radio frequency device, and the radio frequency device adjusts the power of the radio frequency device based on the usage status, so that the power level of the radio frequency device can match the status of the data carried on the first resource, thereby reducing the loss of the communication system.

[0221] FIG. 6 is a schematic flowchart of an information transmitting method 600 according to an embodiment of the present application.

[0222] S601: A network control device determines indication information, the indication information indicating to a radio frequency device to turn off a first module at a first moment, and the first module does not carry first data in a first time resource corresponding to the first moment.

[0223] The radio frequency device may be the RE 120 shown in FIG. 1, and the network control device may be the REC 110 shown in FIG.

[0224] For a description of the first module, the first time resource, and the first instant, please refer to the description of the first module, the first time resource, and the first instant in the method 300. For the sake of brevity, details will not be described here.

[0225] The network control device may schedule and manage the occupancy of the data in the time domain resource, so that the indication information may be determined based on whether the first data occupies the first time resource (part or all of the scheduled time domain resource). When the first data does not occupy the location of the first time resource, the radio frequency device is indicated to turn off the first module at a first moment corresponding to the first time resource.

[0226] The indication information may be turn-off indication information, and the turn-off indication may also be referred to as a symbol power saving indication. The symbol power saving indication may be indicated by different bit values. For example, when the bit is set to "0", it indicates that the radio frequency device turns off the first module, and when the bit is set to "1", it indicates that the radio frequency device turns on the first module.

[0227] In this embodiment of the present application, the network controller may further determine whether to turn off the first module configured to process uplink data or turn off the first module configured to process downlink data.

[0228] Optionally, the network controller determines first information, where the first information indicates that the first module does not carry uplink data in the first time resource, and / or the first information indicates that the first module does not carry downlink data in the first time resource. Alternatively, the first information indicates that the first module is a module configured to process uplink data, or the first information indicates that the first module is a module configured to process downlink data.

[0229] For a description of the first information, please refer to the description of the first information in the method 300. For brevity, details will not be described here.

[0230] In this embodiment of the present application, the network controller may further determine a particular radio frequency channel or a plurality of particular radio frequency channels on which the first module should be turned off.

[0231] Optionally, the network controller determines second information, the second information indicating that the first module corresponding to the radio frequency channel does not carry data in the first time resource. Alternatively, the second information indicates that the first module is a module in the radio frequency channel.

[0232] For a description of the second information, please refer to the description of the second information in the method 300. For the sake of brevity, details will not be described here.

[0233] S602: The radio frequency device receives indication information from the network control device, and in response, the network control device sends the indication information to the radio frequency device.

[0234] The indication information indicates to the radio frequency device to turn off the first module at a first instant in time, such that the first module does not carry the first data in a first time resource corresponding to the first instant in time.

[0235] For a description of sending the indication information by the network controller to the radio frequency device, please refer to the description of step S302 in the method 300. For the sake of brevity, details will not be described here.

[0236] When the network control device further determines the first information, the method 600 may further include:

[0237] Optionally, the network controller sends the first information to the radio frequency device, and correspondingly, the radio frequency device receives the first information from the network controller.

[0238] When the network controller further determines the second information, the method 600 may further include:

[0239] Optionally, the network controller sends the second information to the radio frequency device, and in response, the radio frequency device receives the second information from the network controller.

[0240] The network controller may send the first information, or the second information, or the first information and the second information to the radio frequency device. The implementation is similar to that described in the method 300. For brevity, details are not described here.

[0241] S603: The radio frequency device turns off a first module at a first moment.

[0242] For a description of turning off the first module, please refer to the description of turning off the first module in method 300. For brevity, details will not be described here.

[0243] When the network control device further sends the first information to the radio frequency device, the radio frequency device may further turn off the first module configured to process uplink data and / or the first module configured to process downlink data based on the first information.

[0244] When the network control device further sends second information to the radio frequency device, the radio frequency device may further turn off the first module in the radio frequency channel indicated by the second information.

[0245] When the network control device sends the first information and the second information to the radio frequency device, the radio frequency device may turn off a first module configured to process uplink data and / or a first module configured to process downlink data in the radio frequency channel indicated by the second information.

[0246] For a description of turning off the first module by the radio frequency module, please refer to the description of turning off the first module in the method 300. For brevity, details will not be described here.

[0247] Therefore, in the present application, when the first time resource is not occupied and the first module does not carry data in the first time resource, the network control device may indicate to the radio frequency device to turn off the first module, and by doing so, the loss of the communication system can be effectively reduced.

The processing unit 710 is configured to turn off the first module based on the usage status when the usage status is that the first module does not carry data on the first resource.

[0251] Therefore, in the present application, the network control device may send indication information indicating the usage status of the first resource to the radio frequency device.
