Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a communication method and device. Background Art

[0002] With the development of mobile communication networks, the energy consumption of wireless communication network equipment is increasing. In the energy consumption structure of wireless network equipment, the energy consumption of base station equipment accounts for a relatively high proportion. In order to reduce the energy consumption of base station equipment, the relevant technology provides a symbol shutdown solution, which is a dynamic power control technology that can turn off the uplink low noise power amplifier (LNA) when there is no data received during the symbol period of the uplink signal, or turn off the downlink power amplifier (PA) of the RF module when there is no data sent during the symbol period of the downlink signal, so as to reduce the energy consumption of the base station equipment.

[0003] However, in the face of the high energy consumption of base station equipment, we still need to continue to explore more ways to reduce the energy consumption of base station equipment. Summary of the invention

[0004] The present application provides a communication method and apparatus, which can reduce the energy consumption of network equipment (such as a base station).

[0005] In a first aspect, the present application provides a communication method that can be applied to a first network device. The method includes: scheduling a time slot resource of a first time slot, where the time slot resource of the first time slot is used to transmit a signal between the network device and a terminal device; sending a first message, where the first message includes beam identification information, where the beam identification information is used to indicate whether to perform beam weighting processing on the transmission signal of the first time slot.

[0006] In this method, the first network device can send a first message to the second network device. The beam identification information in the first message indicates that beam weighted processing is not performed on the transmission signal of the first time slot. The second network device can not perform beam weighted processing on the transmission signal of the first time slot as indicated by the beam identification information, which can effectively reduce the energy consumption occupied by executing the beam weighted processing function, thereby reducing the energy consumption of the second network device or the entire base station system.

[0007] In one possible design, the method further includes: acquiring scheduling information, the scheduling information being used to indicate whether the first time slot is scheduled. When the scheduling information indicates that the first time slot is not scheduled, the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot.

[0008] In this design, the first network device can determine whether the first time slot is scheduled based on the scheduling information, and determine whether the beam identification information indicates whether to perform beam weighted processing on the transmission signal of the first time slot based on whether the first time slot is scheduled. When the scheduling information indicates that the first time slot is not scheduled, the beam identification information indicates that beam weighted processing is not performed on the transmission signal of the first time slot. When the scheduling information indicates that the first time slot is scheduled, the beam identification information indicates that beam weighted processing is performed on the transmission signal of the first time slot. This design can be used to indicate to the second network device through the beam identification information not to perform beam weighted processing on the transmission signal of the first time slot in the scenario where there is no scheduling in the uplink time slot or the downlink time slot, that is, there is no business data to be transmitted, thereby reducing energy consumption by not performing beam weighted processing in the scenario where there is no business data to be transmitted, thereby saving energy consumption for network devices without affecting the quality of business data transmission.

[0009] In one possible design, the first message further includes scheduling type information; the scheduling type information is used to indicate whether the first time slot is scheduled. When the scheduling information indicates that the first time slot is not scheduled, the scheduling type information indicates that the first time slot is not scheduled; when the scheduling type information indicates that the first time slot is not scheduled, the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot.

[0010] In this design, the first message also includes scheduling type information. When the scheduling type information indicates that the first time slot is scheduled, the beam identification information indicates that beam weighting processing is performed on the transmission signal of the first time slot. When the scheduling type information indicates that the first time slot is not scheduled, the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot.

[0011] This design can achieve the scenario where there is no scheduling for the uplink time slot or downlink time slot, that is, there is no business data to be transmitted, and the scheduling type information can be used to indicate to the second network device that the uplink time slot or downlink time slot is not scheduled, and the beam identification information can be used to indicate to the second network device that beam weighting processing is not performed on the transmission signal of the first time slot; for the scenario where the uplink time slot or downlink time slot is scheduled, that is, there is business data to be transmitted, the scheduling type information can be used to indicate to the second network device that the uplink time slot or downlink time slot is scheduled, and the beam identification information can be used to indicate to the second network device that beam weighting processing is performed on the transmission signal of the first time slot; thereby, in the scenario where there is no business data to be transmitted, energy consumption can be reduced by not performing beam weighting processing. In this design, when the first network device decides whether to perform beam weighting processing on the transmission signal of the first time slot as indicated by the beam identification information, it only needs to make a decision based on the indication of the scheduling type information, without paying attention to the specific scheduling content of the first time slot.

[0012] In one possible design, the first message includes a control plane message, the control plane message includes resource information, the resource information is used to indicate the time slot resources of the first time slot, and the control plane message is used to indicate that the time slot resources of the first time slot have been scheduled.

[0013] In this design, the first message may be a control plane message sent through the network communication interface between the first network device and the second network device, such as a scheduling and beamforming commands message. Taking the scheduling and beamforming commands message as an example, there is indication information in the scheduling and beamforming commands message, which is used to indicate whether the second network device performs beam weighting processing. In a specific implementation, the indication information is a "section type" field and a "beamID" field. When the value of the "section type" field is not 0, it indicates that the first time slot is scheduled; when the value of the "beamID" field is not 0, it indicates that beam weighting processing is performed on the transmission signal of the first time slot.

[0014] This design can utilize existing control plane messages and add beam identification information to the control plane information to implement the function of instructing the second network device whether to perform beam weighted processing on the transmission signal of the first time slot. The implementation cost is low, such as low protocol modification cost.

[0015] In a possible design, the first message further includes at least one of the following identification information: compression identification information, filtering identification information, and symbol shutoff identification information.

By indicating in the first message whether the second network device performs symbol shutoff on the transmission signal of the first time slot, the second network device does not need to decide whether to perform symbol shutoff on the transmission signal of the first time slot according to the symbol energy detection method.

[0017] In one possible design, when the first time slot is not scheduled, the compression identification information indicates that the in-phase and quadrature-phase signals of the transmission signal of the first time slot are not decompressed or compressed, the filtering identification information indicates that the transmission signal of the first time slot is not filtered, and the symbol-off identification information indicates that the symbol of the transmission signal of the first time slot is off.

[0083] With the development of mobile communication networks, the energy consumption of wireless communication network equipment is increasing. In the energy consumption structure of wireless network equipment, the energy consumption of base station equipment accounts for a relatively high proportion. In order to reduce the energy consumption of base station equipment, the relevant technology provides a symbol shutdown solution, which is a dynamic power control technology that can turn off the uplink low noise power amplifier (LNA) when there is no data received during the symbol period of the uplink signal, or turn off the downlink power amplifier (PA) of the RF module when there is no data sent during the symbol period of the downlink signal, so as to reduce the energy consumption of the base station equipment.

[0084] For example, when the service load of the base station is in no-load or light-load state, some uplink time slots or downlink time slots have idle channels (the period where the symbol is located is idle), and no uplink data is received or downlink data is sent. The base station can implement symbol shutoff, turning off the LNA or PA in the idle channel (or in the idle symbol period) to save energy consumption of the base station equipment.

[0085] For example, Figure 1 FIG. 1 shows a schematic diagram of the principle of symbol shutdown. Figure 1 As shown, in the 5G NR system, the base station turns off the PA in the idle channel of the downlink time slot, and a time slot is 1 millisecond (ms). For a normal cyclic prefix, a time slot can include 14 orthogonal frequency division multiplexing (OFDM) symbols. Each time slot may include a control channel, a data channel and / or an idle channel. The OFDM symbol of the control channel can be called a control signal, and the OFDM signal of the data channel can be called a data signal. The OFDM symbol where the idle channel is located can be called an idle signal. The control channel is used to transmit control information, schedule resources, and manage system signals. The data channel is used to carry data.

[0086] The base station can detect whether there is data carried in each channel period in the downlink time slot. For the symbol period where the idle channel is located, the PA can be turned off in the channel or symbol period to reduce energy consumption. For example, the baseband subsystem of the base station can perform baseband processing on the subframe data scheduled by the medium access control (MAC) layer, such as scrambling, modulation, layer mapping, precoding, resource element (RE) mapping, inverse fast fourier transform (iFFT), cyclic prefix (CP) addition, etc., to convert the data stream from the frequency domain to the time domain and send it to the intermediate frequency subsystem. The intermediate frequency chip of the intermediate frequency subsystem can perform power energy detection on each symbol in the time domain data stream, and turn off the PA if it is empty. Among them, the symbol power energy detection being empty can mean: the first part of the sample points in the CP indication of the detected symbol is 0. That is, when the symbol power energy detection is empty, it can be indicated that the symbol is an idle signal that does not carry data (that is, the channel is an idle channel), and the PA can be turned off in the symbol period of the idle channel or idle signal. For Figure 1 The distribution of OFDM symbols in the partial time slot is shown. The on or off state of the PA can be referred to Figure 1 The line used to indicate whether the PA is on or off. If the line is on, it means the PA is on, and if the line is on the bottom, it means the PA is off. For example: Figure 1 In the second time slot, the second control channel can turn off the PA, and the 6th to 12th idle channels can turn off the PA.

[0087] However, in the face of the high energy consumption of base station equipment, we still need to continue to explore more ways to reduce the energy consumption of base station equipment.

[0088] To this end, an embodiment of the present application provides a communication method that can be applied to a network device in a communication system. The communication system may include: a network device and a terminal device. The terminal device may communicate with the network device, such as transmitting a signal. The network device may include a first network device and a second network device, the first network device may be used to schedule time slot resources, and the second network device may transmit a signal to the terminal device according to the time slot resources scheduled by the first network device, such as the signal may carry service data.

[0089] In this method, the first network device can schedule the time slot resources of the first time slot, and the time slot resources of the first time slot are used to transmit signals between the network device and the terminal device. The first network device can send a first message to the second network device, and the first message includes beam identification information, and the beam identification information is used to indicate whether to perform beam weighting processing on the transmission signal of the first time slot. After the second network device receives the first message, when the beam identification information indicates that beam weighting processing is to be performed on the transmission signal of the first time slot, the second network device may perform beam weighting processing on the transmission signal of the first time slot when transmitting signals between the second network device and the terminal device. Alternatively, when the beam identification information indicates that beam weighting processing is not to be performed on the transmission signal of the first time slot, the second network device may not perform beam weighting processing on the transmission signal of the first time slot when transmitting signals between the second network device and the terminal device.

[0090] The first time slot may refer to any one or more time slots or each time slot.

[0091] This method can be used to instruct the first network device to the second network device whether the second network device needs to perform beam weighting processing on the transmission signal of the first time slot when transmitting signals between the second network device and the terminal device. When the second network device does not perform beam weighting processing on the transmission signal of the first time slot according to the instruction of the first network device, the energy consumption of the network device (such as the second network device) can be effectively reduced.

[0092] In some embodiments, the above-mentioned communication system may include: at least one terminal device and at least one network device.

[0093] Among them, the network device can also be called a wireless access network device or a next-generation wireless access network device. The terminal device can communicate with the network device. The network device can provide the terminal device with functional services such as wireless resource management, service quality management, data encryption and compression. Different network devices can communicate with each other through the Xn interface. Different terminal devices can exchange information and communicate with each other through the network device.

[0094] The terminal device is located within the coverage of one or more cells (carriers) provided by the network device, and the cell serving the terminal device may be one or more. When there are multiple serving cells for the terminal device, the terminal device may operate in CA, dual connectivity (DC), or coordinated multi-point transmission mode.

[0095] Optionally, the communication system can be a wideband code division multiple access (WCDMA) system, a long term evolution (LTE) system, an advanced long term evolution LTE-A (LTE advanced) system, an LTE frequency division duplex (FDD) system, a universal mobile telecommunication system (UMTS), a 5G NR system, and other wireless communication systems that apply OFDM technology, etc. This application does not limit the specific type of the communication system.

[0096] For example, when the communication system is a 5G NR system, the communication system may also include a core network device, and the core network device and the network device may communicate through a next generation (NG) interface.

[0097] Optionally, the terminal equipment in the communication system may also be referred to as user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may refer to a device that provides voice and / or data connectivity to a user, for example, a mobile phone ("cellular" phone), a mobile phone, a computer, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a laptop computer, a handheld communication device, a handheld computing device, a satellite wireless device, a wireless modem card, a TV set top box (STB), a customer premises equipment (CPE), a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.), an in-vehicle device (such as a car, a bicycle, an electric car, an airplane, a ship, a train, a high-speed train, etc.), a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a smart home device (such as a refrigerator, a TV, an air conditioner, an electric meter, etc.), an intelligent robot, a workshop device, a wireless terminal in self-driving, a remote medical The present application does not limit the specific form of the terminal device.

[0098] The network device may be an access network device of the communication system, such as a base station. Optionally, in an embodiment of the present application, the network device may include various forms of macro base stations, micro base stations (also called small stations), etc. For example, the network device may include: a base station in the aforementioned WCDMA or LTE, a next generation base station (next generation nodeB, gNB), a next generation evolved nodeB (ng-eNB), a transmission reception point (transmission reception point, TRP), an evolved Node B (evolved Node B, eNB), a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (for example, home evolved NodeB, or homeNode B, HNB), a base band unit (base band unit, BBU), or a wireless fidelity (wireless fidelity, Wifi) access point (access point, AP), etc.

[0099] It is understandable that the aforementioned communication system is only for the purpose of more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided by the embodiment of the present application. For example, the communication system may also include other devices, such as: a network control device. The network control device may be an operation administration and maintenance (OAM) system, also known as a network management system. The network control device may manage the aforementioned network devices.

[0100] Corresponding to the communication system, the network equipment described in the embodiments of the present application can be a base station system based on the fourth generation mobile information technology (the 4th generation mobile communication technology, 4G), or a base station system based on the fifth generation mobile information technology (the 5th generation mobile communication technology, 5G), or a base station system based on the sixth generation mobile information technology (the 6th generation mobile communication technology, 6G), and may even be suitable for base station systems or fronthaul networks in future communication networks in the future, without specific limitation.

[0101] In some embodiments, the first network device may be a control network element, and the second network device may be an execution network element. The control network element may be used to schedule time slot resources, and the execution network element may transmit signals to the terminal device according to the time slot resources scheduled by the control network element. The control network element may send a first message to the execution network element, and the first message includes beam identification information, and the beam identification information is used to indicate whether to perform beam weighting processing on the transmission signal of the first time slot. The execution network element may not perform beam weighting processing on the transmission signal of the first time slot, or may perform beam weighting processing on the transmission signal of the first time slot according to the indication of the beam identification information.

[0102] Exemplarily, the control network element and the execution network element are connected in communication via a communication interface. The control network element may be a network element that controls service processing, and can collect information related to the execution network element from the execution network element via the communication interface, and send control information to the execution network element to control the execution network element. The execution network element is a network element that performs corresponding service processing according to the control information sent by the control network element.

[0103] In addition, the communication interface between the aforementioned control network element and the execution network element may be a transmission protocol interface based on a transmission interface such as a backplane bus, optical fiber, radio frequency cable, copper axis cable, high-speed serial cable, etc. Exemplarily, when the communication interface uses a transmission medium such as a backplane bus or optical fiber, the communication interface may be an interface based on the common public radio interface (CPRI) protocol, or an interface based on the enhanced common public radio interface (eCPRI) protocol, or an interface based on the CPRI derivative (Similar CPRI, sCPRI) protocol, or other fronthaul network interfaces. Exemplarily, when the communication interface uses a transmission medium such as a radio frequency cable, copper axis cable or high-speed serial cable, the communication interface may be an interface based on the antenna interface standards group (AISG) protocol or an interface based on the Ethernet protocol, and the specific details are not limited.

[0104] Optionally, an intermediate network element may be further included between the control network element and the execution network element. The intermediate network element is used to connect the aforementioned control network element and the execution network element, and to forward the signaling between the control network element and the execution network element. Optionally, the intermediate network element may also implement an interface conversion function. When the execution network element and the control network element support different communication interfaces respectively, the intermediate network element may implement interface protocol conversion so that the control network element and the execution network element using different interface protocols can communicate with each other. For example, when the control network element supports functions above the interface based on the eCPRI protocol (for example, functions above the high physical layer (PHY-High)), and the execution network element supports functions below the interface based on the CPRI protocol (for example, functions below the radio frequency function), the intermediate network element connecting the aforementioned control network element and the execution network element may have various functions of the low physical layer (PHY-Low) (for example, precoding, resource element / particle (RE) mapping, RE inverse mapping, etc.), so that the control network element supporting the eCPRI protocol and the execution network element supporting the CPRI protocol can communicate with each other.

[0105] Optionally, the control network element may include a non-real-time control network element and a real-time control network element. The non-real-time control network element may be connected to at least one real-time control network element, and the real-time control network element may be connected to at least one execution network element. An execution network element may also be connected to another execution network element.

[0106] Among them, the non-real-time control network element is a network element in the base station system for performing non-real-time control processing, and is used to configure the commands or parameters used in the real-time control processing process for the real-time control network element and / or the execution network element. The non-real-time control network element may be a network element that supports non-real-time wireless high-layer protocol stack functions. Exemplarily, the non-real-time control network element may be a centralized unit (CU) in a traditional base station system. Exemplarily, the non-real-time control network element may be a non-real-time control unit that is independent of the CU in traditional technology and can realize the functions of the non-real-time control network element, or it may be a network element realized by combining the CU in traditional technology and the aforementioned non-real-time control unit. Optionally, the non-real-time control network element may also have the functions of partial baseband processing. In this case, the non-real-time control network element may be a baseband unit (BBU).

[0107] The real-time control network element is a network element in the base station system for real-time control processing, and is used to control the execution network element to perform real-time control functions according to the commands or parameters configured by the non-real-time control network element. The real-time control network element is a network element or device with baseband signal processing functions, or a device with wireless signal processing for managing the access network (radio access network, RAN). The real-time control network element can complete baseband signal processing functions such as coding, multiplexing, modulation and spread spectrum, can complete the function of processing signaling from the execution network element (for example, the radio frequency unit or antenna device), and can realize the function of local management and remote operation and maintenance of the execution network element. Optionally, the real-time control network element is a layer 2 functional network element that processes physical layer functions and real-time requirements. Exemplarily, the real-time control network element can be a distributed unit (DU). Exemplarily, the real-time control network element can be a real-time control unit that is independent of the DU in the traditional technology and can realize the function of the real-time control network element, or it can be a network element realized by combining the DU in the traditional technology and the aforementioned real-time control unit. In addition, the real-time control network element can also be a baseband unit BBU.

[0108] The execution network element is a network element that executes real-time control services in the base station system. The execution network element can receive real-time control information from the real-time control network element, and then perform corresponding real-time control service processing based on the aforementioned real-time control information. The execution network element can be a network element that processes wireless signal (for example, intermediate frequency signal, radio frequency signal, etc.) related services. For example, a radio unit (RU), a remote radio unit (RRU), and a remote radiohead (RRH). The execution network element can also be an antenna device connected to the network element that processes the aforementioned radio frequency-related services, such as an antenna line device (ALD) (also known as an antenna linear device). In addition, the execution network element can also be a combination of the aforementioned radio frequency unit and the antenna device. For example, in a 5G NR system, the aforementioned execution network element can also be an active antenna processing unit (AAU), that is, a processing unit integrated with an RRU (or RRH) and an antenna device.

[0109] It should be understood that the aforementioned intermediate network element can be used to connect the real-time control network element and the execution network element, and can also be used to connect a certain execution network element with another execution network element. Exemplarily, if the real-time control network element is a baseband unit and the execution network element is a wireless unit, the intermediate network element can be an intermediate unit (baseband radio middle unit, BRMU) connecting the baseband unit and the wireless unit (for example, a baseband gateway, a radio frequency hub RRU HUB and various extended network elements); if the execution network element is a wireless unit, and the antenna device is another execution network element that needs to be connected to the wireless unit, the intermediate network element can also be an intermediate unit (radio antenna middle unit, RAMU) connecting the wireless unit and the antenna device. It should be understood that when the intermediate network element is a BRMU, the intermediate network element can have some functions of the connected baseband unit (for example, DU or BBU) or wireless unit (for example, RU or RRU) to facilitate the connection of baseband units and wireless units with different performance parameters (for example, device version, device interface or protocol version, etc.) on both sides. When the intermediate network element is a RAMU, the intermediate network element can have some functions of the connected radio frequency unit (for example, RU or RRU) or antenna device (for example, ALD) to facilitate the docking of wireless units and antenna devices with different performance parameters (for example, device version, device interface or protocol version, etc.) on both sides.

[0110] In one possible design, the first network device may be an open distributed unit (O-DU), and the second network device may be an open radio unit (O-RU).

[0111] For example, Figure 2 FIG. 1 shows a schematic diagram of the composition of a base station system provided in an embodiment of the present application. Figure 2 As shown, the base station system 20 may include an O-DU 21 and at least one O-RU 22. The O-DU 21 and the O-RU 22 are communicatively connected. In an embodiment of the present application, the O-DU 21 may be used to schedule time slot resources, and the O-RU 22 may transmit signals to and from the terminal device according to the time slot resources scheduled by the O-DU 21. The O-DU 21 may send a first message to the O-RU 22, and the first message includes beam identification information, and the beam identification information is used to indicate whether to perform beam weighting processing on the transmission signal of the first time slot. The O-RU 22 may not perform beam weighting processing on the transmission signal of the first time slot, or may perform beam weighting processing on the transmission signal of the first time slot according to the indication of the beam identification information.

[0112] Among them, O-DU 21 is an open control network element, responsible for controlling and managing the entire wireless network system. O-RU 22 is an open radio frequency network element, responsible for performing radio frequency signal processing and radio frequency signal transmission at the physical layer. O-DU and O-RU can communicate through optical fiber or wireless connection and work together to provide wireless communication services.

[0113] Figure 3 FIG. 1 shows a schematic diagram of a network device provided in an embodiment of the present application. The network device may be the first network device or the second network device. Figure 3 As shown, the network device may include: at least one processor 31 , a memory 32 , a communication interface 33 , and a bus 34 .

[0114] The processor 31 is the control center of the network device, which can be a processor or a general term for multiple processing elements. For example, the processor 31 can be a central processing unit (CPU), an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present application, such as one or more microprocessors (digital signal processors, DSPs), or one or more field programmable gate arrays (FPGAs).

[0115] The processor 31 can execute various functions of the network device by running or executing the software program stored in the memory 32, and calling the data stored in the memory 32. For example, when the network device is a first network device, the steps performed by the first network device in the communication method provided in the embodiment of the present application can be executed. For another example, when the network device is a second network device, the steps performed by the second network device in the communication method provided in the embodiment of the present application can be executed.

[0116] In a specific implementation, as an embodiment, the processor 31 may include one or more CPUs, such as Figure 3 CPU0 and CPU1 are shown in the figure.

[0117] In a specific implementation, as an embodiment, the network device may include multiple processors, such as Figure 331 and processor 35 are shown in FIG. Each of these processors may be a single-core processor (single-CPU) or a multi-core processor (multi-CPU). A processor herein may refer to one or more devices, circuits, and / or processing cores for processing data (e.g., computer program instructions).

[0118] The memory 32 can store the software program of the method steps executed by the network device, and the execution is controlled by the processor 31. The memory 32 can be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical disc, laser disc, optical disc, digital versatile disc, Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto.

[0119] The memory 32 may exist independently and be connected to the processor 31 via the bus 34. Alternatively, the memory 32 may be integrated with the processor 31, which is not limited here.

[0120] The communication interface 33 uses any transceiver or other device for communicating with other devices or communication networks. The communication interface 33 may be an Ethernet interface, a radio access network (RAN) interface, a wireless local area network (WLAN) interface, etc. The communication interface 33 may include a receiving unit to implement a receiving function, and a sending unit to implement a sending function.

[0121] The bus 34 may be an industry standard architecture (ISA) bus, a peripheral component interconnect (PCI) bus, or an extended industry standard architecture (EISA) bus. The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 3 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0122] Although attached Figure 3 The bus 34 is used in the embodiment, but it is understandable that the bus can also be replaced by other forms of connection relationships and is not limited to the bus itself.

[0123] The following is the above Figure 2 Taking the base station system shown as an example, the communication method provided in the embodiment of the present application is exemplarily described in combination with the accompanying drawings.

[0125] It should be noted that, in the description of the present application, the words "first", "second", etc. are only used to distinguish the description and are not used to specifically limit a certain feature. In the description of the embodiments of the present application, "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0126] Figure 4 FIG. 1 is a flow chart showing a communication method provided by an embodiment of the present application. Figure 4 As shown, the communication method may include S401-S403.

[0127] S401. A first network device schedules time slot resources of a first time slot.

[0128] The time slot resource of the first time slot is used to transmit signals between the network device and the terminal device. The first time slot may be any one or more time slots, or the first time slot may refer to each time slot.

[0129] Time slot resource scheduling refers to the process of rationally allocating and scheduling time slot resources in a wireless communication system. The communication system can divide time into a series of time slots, each of which is used to transmit data of one or more users. The goal of time slot resource scheduling is to maximize the system throughput, improve the transmission quality of users, and meet the communication needs of different users.

[0130] Time slot resource scheduling usually includes multiple aspects such as allocating time slots, scheduling time slots, power control, and frequency selection. Allocating time slots means determining the number and location of time slots allocated to each UE based on the communication needs of the user equipment (UE) and the resources of the communication system. Scheduling time slots means dynamically adjusting the time slot allocation of the UE based on factors such as the UE priority and communication quality to maximize the performance of the system. Power control means adjusting the UE's transmit power based on the UE's signal quality and interference to improve the capacity and coverage of the communication system. Frequency selection means selecting appropriate frequency resources for communication based on the utilization of spectrum resources to reduce interference and increase system capacity.

[0131] In other words, the first network device scheduling the time slot resources of the first time slot may refer to the first network device allocating the first time slot to the UE and scheduling the first time slot as a time slot resource for transmitting signals (such as transmitting service data) with the UE. After the time slot resource scheduling of the first time slot is completed, the second network device transmits signals between the UE and the UE in the first time slot according to the time slot resources of the first time slot. For example, when the first time slot is an uplink time slot, the second network device can receive uplink data from the UE in the first time slot, and when the second time slot is a downlink time slot, the second network device can send downlink data to the UE in the first time slot.

[0132] S402. The first network device sends a first message to the second network device, where the first message includes beam identification information, and the beam identification information indicates that beam weighting processing is not performed on a transmission signal in a first time slot.

[0133] Accordingly, the second network device receives the first message.

[0134] In this embodiment, the first network device may send a first message to the second network device after scheduling the time slot resources of the first time slot, and the first message may include beam identification information, such as an identification ID (beamID). The beam identification information may indicate to the second network device that beam weighting processing is not performed on the transmission signal of the first time slot.

[0135] Optionally, the first message may be a message sent directly from the first network device to the second network device via a communication interface between the first network device and the second network device, or a message sent indirectly to the second network device via other communication interfaces, which is not limited in the present application.

[0136] S403: The second network device does not perform beam weighting processing on the transmission signal of the first time slot.

[0137] Exemplarily, when the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot, that is, when the beam identification information indicates no, the second network device may not perform beam weighting processing on the transmission signal of the first time slot.

[0138] For example, when the second network device and the UE transmit signals in the first time slot, beam weighting processing may not be performed on the transmission signal in the first time slot.

[0139] Taking the first network device as O-DU and the second network device as O-RU as an example, the open radio access network (O-RAN) protocol clarifies the functional division of O-DU and O-Ru in the eNB or gNB system architecture. Taking the NR downlink physical downlink shared channel (PDSCH) data as an example, Figure 5 FIG. 2 shows a schematic diagram of the functional division between the O-DU and the O-RU provided in an embodiment of the present application. Figure 5 As shown, O-DU can perform scrambling, modulation, layer mapping, precoding, resource mapping, IQ compression and other functions on downlink data. O-RU can perform IQ decompression, digital beamforming, iFFT and CP addition, digital to analog, and analog beamforming on downlink data.

[0140] Among them, O-DU can receive digital signal streams from the core network. These digital signal streams may be coded and modulated data streams, which need to be decoded and demodulated to restore to the original data. In O-DU, the modulation function can decode and demodulate the received digital signal stream and convert it into original data. The layer mapping function can map the transmission signal of the physical layer to different transmission layers for decoding at the receiving end. For example, the data of the transmission layer can be divided into multiple layers, and each layer is transmitted through different channels. The precoding function can linearly combine multiple data streams so that different data streams can be better separated at the receiving end, improving the reliability and capacity of signal transmission. The resource mapping function can map logical channels to physical resource elements and determine the position of each logical channel on the physical resources for scheduling and allocation during the transmission process. The IQ signal compression function can be used to compress IQ signals.

[0141] The O-RU may include a radio frequency module, which may receive a digital signal stream from the O-DU and convert it into a radio frequency signal. The IQ signal decompression function may decompress the IQ signal compressed by the O-DU. The digital beam weighting function may perform beam weighting on the digital signal. The frequency domain to time domain conversion function may convert the digital signal stream from the frequency domain to the time domain. The digital-to-analog conversion function may convert the digital signal stream into an analog signal stream. The analog beam weighting function may perform analog beam weighting on the analog signal stream. The radio frequency module may also amplify the modulated radio frequency signal through the PA to increase the amplitude of the signal to achieve appropriate transmission power. The radio frequency module may also perform frequency selection on the radio frequency signal through a filter to filter out unnecessary frequency components so that the spectrum of the signal meets the specified bandwidth requirements. The radio frequency module may wirelessly transmit the modulated and amplified radio frequency signal through the antenna to send downlink data to the UE.

[0142] In this embodiment, for each UE, the O-DU can schedule time slot resources for transmitting signals between the UE, such as the time slot resources of the first time slot. After the scheduling is completed, the O-DU can send a first message to the O-RU, and the first message includes beam identification information, and the beam identification information can indicate that beam weighting processing is not performed on the transmission signal of the first time slot. After receiving the downlink data sent by the O-DU, the O-RU can send downlink data to the UE in the first time slot through the transmission signal of the first time slot. When the beam identification information in the first message indicates that beam weighting processing is not performed on the transmission signal of the first time slot, the O-RU may not perform beam weighting processing on the transmission signal of the first time slot when sending downlink data to the UE in the first time slot.

[0143] In a possible design, not performing beam weighted processing on the transmission signal of the first time slot may mean not performing analog beam weighted processing on the transmission signal of the first time slot.

[0144] In another possible design, not performing beam weighted processing on the transmission signal of the first time slot may mean not performing digital beam weighted processing on the transmission signal of the first time slot.

[0145] In another possible design, not performing beam weighted processing on the transmission signal of the first time slot may mean not performing digital beam weighted processing and analog beam weighted processing on the transmission signal of the first time slot.

[0146] Exemplarily, the O-RU not performing analog beam weighting processing on the transmission signal of the first time slot may include: the O-RU turning off the phase shifter in the first time slot to achieve not performing analog beam weighting processing on the transmission signal of the first time slot. In other words, not performing analog beam weighting processing on the transmission signal of the first time slot may be turning off the phase shifter in the first time slot.

[0147] Exemplarily, the O-RU does not perform digital beam weighting processing on the transmission signal of the first time slot, which may include: the O-RU shuts down a digital signal processor (DSP) for implementing the digital beam weighting function in the first time slot, or does not perform the step of performing digital beam weighting processing by the digital signal processor. Optionally, the digital signal processor for implementing the digital beam weighting function may be a dedicated processor for implementing digital beam weighting processing.

[0148] In this embodiment, the first network device sends a first message to the second network device. The beam identification information in the first message indicates that beam weighted processing is not performed on the transmission signal of the first time slot. The second network device does not perform beam weighted processing on the transmission signal of the first time slot in accordance with the instruction of the beam identification information. This can effectively reduce the energy consumption occupied by executing the beam weighted processing function, thereby reducing the energy consumption of the second network device or the entire base station system.

[0149] In some other embodiments, the beam identification information in the first message may also indicate that beam weighting processing is performed on the transmission signal of the first time slot. Figure 6 Another flow chart of the communication method provided by the embodiment of the present application is shown. Figure 6 As shown, the communication method may include S601-S603.

[0150] S601. A first network device schedules time slot resources of a first time slot.

[0151] The time slot resources of the first time slot are used to transmit signals between the network device and the terminal device.

[0152] S601 may refer to the above-mentioned S401, which will not be described in detail here.

[0153] S602: The first network device sends a first message to the second network device, where the first message includes beam identification information, and the beam identification information indicates that beam weighted processing is to be performed on a transmission signal of a first time slot.

[0154] S602 may also refer to the above S402, except that, in this embodiment, the beam identification information indicates that beam weighting processing is performed on the transmission signal of the first time slot.

[0155] S603: The second network device performs beam weighting processing on the transmission signal of the first time slot.

[0156] Similar to the above S403, in this embodiment, when the beam identification information in the first message indicates that beam weighted processing is to be performed on the transmission signal of the first time slot, the second network device can perform beam weighted processing on the transmission signal of the first time slot when transmitting a signal to the UE in the first time slot.

[0157] For example, also taking the scenario of sending downlink data to the UE described in the aforementioned embodiment as an example, after receiving the downlink data sent by the O-DU, the O-RU can send the downlink data to the UE in the first time slot through the transmission signal of the first time slot. When the beam identification information in the first message indicates that the transmission signal of the first time slot is to be beam-weighted, when the O-RU sends downlink data to the UE in the first time slot, the transmission signal of the first time slot can be beam-weighted.

[0158] Similar to the above embodiment, the beam weighting processing may include digital beam weighting processing and / or analog beam weighting processing.

[0159] Exemplarily, the O-RU performs beam weighted processing on the transmission signal of the first time slot, which may include: the O-RU keeps the phase shifter turned on in the first time slot to perform beam weighted processing on the transmission signal of the first time slot through the phase shifter.

[0160] Exemplarily, the O-RU performs digital beam weighted processing on the transmission signal of the first time slot, which may include: the O-RU keeps a digital signal processor (digital signal processor, DSP) for implementing the digital beam weighting function turned on in the first time slot, or executes the step of performing digital beam weighted processing through the digital signal processor.

[0161] Optionally, the first time slot described in the embodiment of the present application may be an uplink time slot or a downlink time slot. That is, the first time slot includes an uplink time slot and / or a downlink time slot. For the two scenarios where the first time slot is an uplink time slot and a downlink time slot, the communication method provided in the embodiment of the present application can be applied, and is not limited here.

[0162] Based on the above embodiments, the present application actually provides a communication method applied to a first network device and a communication method applied to a second network device, respectively. In the communication method applied to the first network device, the first network device can schedule the time slot resources of the first time slot and send a first message, the first message includes beam identification information, and the beam identification information is used to indicate whether to perform beam weighting processing on the transmission signal of the first time slot. In the communication method applied to the second network device, the second network device can receive the first message, the first message includes beam identification information, and the beam identification information is used to indicate whether to perform beam weighting processing on the transmission signal of the first time slot; when the beam identification information indicates no, beam weighting processing is not performed on the transmission signal of the first time slot. When the beam identification information indicates yes, beam weighting processing is performed on the transmission signal of the first time slot.

[0163] Optionally, in an embodiment of the present application, the beam identification information specifically indicates whether to perform beam weighting processing on the transmission signal of the first time slot, which can be determined by the first network device.

[0164] For example, in some embodiments, for some business data transmission scenarios, the first network device may determine that the beam identification information indicates that beam weighted processing is to be performed on the transmission signal of the first time slot. For other business data transmission scenarios, the first network device may determine that the beam identification information indicates that beam weighted processing is not to be performed on the transmission signal of the first time slot. Among them, which business data transmission scenarios are scenarios where the beam identification information needs to indicate that beam weighted processing is not to be performed on the transmission signal of the first time slot can be pre-defined, or, according to pre-defined rules, identified by the first network device according to pre-defined rules, and there is no limitation here.

[0165] In some other embodiments, after completing the time slot resource scheduling of the first time slot, the first network device can also determine, based on the scheduling information of the first time slot, whether the beam identification information indicates that beam weighted processing is to be performed on the transmission signal of the first time slot, or whether the beam identification information indicates that beam weighted processing is not to be performed on the transmission signal of the first time slot.

[0166] For example, in one possible design, the communication method may further include: the first network device obtains scheduling information, where the scheduling information is used to indicate whether the first time slot is scheduled. When the scheduling information indicates that the first time slot is not scheduled, the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot. When the scheduling information indicates that the first time slot is scheduled, the beam identification information indicates that beam weighting processing is performed on the transmission signal of the first time slot.

[0167] For example, Figure 7 FIG. 2 shows another flow chart of the communication method provided in the embodiment of the present application. Figure 7As shown, for the scenario where there is no scheduling in the first time slot, the communication method may include S701-S704.

[0168] S701. A first network device schedules time slot resources of a first time slot.

[0169] S701 may refer to the above-mentioned S401, which will not be described in detail here.

[0170] S702: The first network device obtains scheduling information, where the scheduling information indicates that there is no scheduling in the first time slot.

[0171] The scheduling information may be a scheduling result of the time slot resources of the first time slot.

[0172] Taking the first time slot as a downlink time slot as an example, in the time slot resource scheduling process, the first network device (such as O-DU) can make scheduling decisions based on factors such as network conditions and UE requirements to determine the downlink data that needs to be sent. When there is no downlink data that needs to be sent in the downlink time slot, the scheduling result of the time slot resources of the downlink time slot can be empty, indicating that the downlink time slot is not scheduled. When there is downlink data that needs to be sent in the downlink time slot, the scheduling result of the time slot resources of the downlink time slot is not empty, indicating that the downlink time slot is scheduled.

[0173] Similarly, for the uplink time slot, during the time slot resource scheduling process, the first network device (such as O-DU) can make scheduling decisions based on factors such as network conditions and UE requirements to determine whether there is uplink data that needs to be received by the O-RU. When there is no uplink data that needs to be received in the uplink time slot, the scheduling result of the time slot resources of the uplink time slot can be empty, indicating that the uplink time slot is not scheduled. When there is uplink data that needs to be received in the uplink time slot, the scheduling result of the time slot resources of the uplink time slot is not empty, indicating that the uplink time slot is scheduled.

[0174] The scheduling information described in S702 may indicate whether the first time slot is scheduled according to the scheduling result of the time slot resource of the first time slot. When the scheduling information indicates that the first time slot is not scheduled, S703 may be executed.

[0175] S703: The first network device sends a first message to the second network device, where the first message includes beam identification information, and the beam identification information indicates that beam weighting processing is not performed on a transmission signal in the first time slot.

[0176] Accordingly, the second network device receives the first message.

[0177] S704: The second network device does not perform beam weighting processing on the transmission signal of the first time slot.

[0178] S703-S704 may refer to the above-mentioned S402-S403, and will not be described in detail here.

[0179] For example, Figure 8 FIG. 2 shows another flow chart of the communication method provided in the embodiment of the present application. Figure 8 As shown, for the scenario where there is scheduling in the first time slot, the communication method may include S801-S804.

[0180] S801. A first network device schedules time slot resources of a first time slot.

[0181] S801 may refer to the above-mentioned S401, which will not be described in detail here.

[0182] S802: The first network device obtains scheduling information, where the scheduling information indicates that there is scheduling in the first time slot.

[0183] As described in S702 above, the scheduling information may indicate whether the first time slot is scheduled according to the scheduling result of the time slot resource of the first time slot. When the scheduling information indicates that the first time slot is scheduled, S803 may be executed.

[0184] S803. The first network device sends a first message to the second network device, where the first message includes beam identification information, and the beam identification information indicates that beam weighted processing is to be performed on a transmission signal of a first time slot.

[0185] Accordingly, the second network device receives the first message.

[0186] S804: The second network device performs beam weighting processing on the transmission signal of the first time slot.

[0187] S803-S804 may refer to the above-mentioned S602-S603, and will not be described in detail here.

[0188] In this design, the first network device can determine whether the first time slot is scheduled based on the scheduling information, and determine whether the beam identification information indicates whether to perform beam weighted processing on the transmission signal of the first time slot based on whether the first time slot is scheduled. When the scheduling information indicates that the first time slot is not scheduled, the beam identification information indicates that beam weighted processing is not performed on the transmission signal of the first time slot. When the scheduling information indicates that the first time slot is scheduled, the beam identification information indicates that beam weighted processing is performed on the transmission signal of the first time slot. This design can be used to indicate to the second network device through the beam identification information not to perform beam weighted processing on the transmission signal of the first time slot in the scenario where there is no scheduling in the uplink time slot or the downlink time slot, that is, there is no business data to be transmitted, thereby reducing energy consumption by not performing beam weighted processing in the scenario where there is no business data to be transmitted, thereby saving energy consumption for network devices without affecting the quality of business data transmission.

[0189] In a possible design, the first message may further include scheduling type information. The scheduling type information is used to indicate whether the first time slot is scheduled. For the first network device, it may be determined, based on the indication of the scheduling information, whether the scheduling type information indicates that the first time slot is scheduled, and based on the indication of the scheduling type information, it may be determined that the beam identification information indicates that beam weighted processing is performed on the transmission signal of the first time slot, or that the beam identification information indicates that beam weighted processing is not performed on the transmission signal of the first time slot.

[0190] For example, when the scheduling information indicates that the first time slot is not scheduled, the scheduling type information may indicate that the first time slot is not scheduled; when the scheduling type information indicates that the first time slot is not scheduled, the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot. Alternatively, when the scheduling information indicates that the first time slot is scheduled, the scheduling type information may indicate that the first time slot is scheduled; when the scheduling type information indicates that the first time slot is scheduled, the beam identification information indicates that beam weighting processing is performed on the transmission signal of the first time slot.

[0191] Compared with the foregoing embodiment, in this embodiment, the first message may further include scheduling type information for indicating whether the first time slot is scheduled.

[0192] For example, Fig. 9 FIG. 2 shows another flow chart of the communication method provided in the embodiment of the present application. Fig. 9 As shown, for the scenario where there is no scheduling in the first time slot, the communication method may include S901-S903.

[0193] S901. A first network device schedules time slot resources of a first time slot.

[0194] S901 may refer to the above-mentioned S401, S701-S702, etc., and will not be repeated here.

[0195] S902. The first network device sends a first message to the second network device, where the first message includes beam identification information and scheduling type information, where the scheduling type information indicates that there is no scheduling in the first time slot, and the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot.

[0196] Accordingly, the second network device receives the first message.

[0197] Exemplarily, the scheduling type information indicates that the first time slot is not scheduled, or the scheduling type information indicates that the first time slot is scheduled, which can be determined by the scheduling result of the time slot resource of the first time slot (such as the above-mentioned scheduling information). The beam identification information indicates whether beam weighted processing is performed on the transmission signal of the first time slot, which can be determined by the indication of the scheduling type information. When the scheduling type information indicates that the first time slot is not scheduled, the beam identification information indicates that beam weighted processing is not performed on the transmission signal of the first time slot. Alternatively, when the scheduling type information indicates that the first time slot is scheduled, the beam identification information indicates that beam weighted processing is performed on the transmission signal of the first time slot.

[0198] S903: The second network device does not perform beam weighting processing on the transmission signal of the first time slot.

[0199] S903 may refer to the above-mentioned S403, which will not be described in detail here.

[0200] and Fig. 9 The scenario shown is similar. For the scenario where the first time slot is scheduled, the first message may also include beam identification information and scheduling type information. The difference is that the scheduling type information indicates that the first time slot is scheduled, and the beam identification information indicates that beam weighting processing is performed on the transmission signal of the first time slot. The second network device may perform beam weighting processing on the transmission signal of the first time slot according to the indication of the scheduling type information and the beam identification information. This will not be described here through the drawings.

[0201] In this design, the first message sent by the first network device to the second network device may include beam identification information and scheduling type information. The scheduling type information may indicate whether the first time slot is scheduled, and the beam identification information indicates whether beam weighting processing is performed on the transmission signal of the first time slot. When the scheduling type information indicates that the first time slot is scheduled, the beam identification information indicates that beam weighting processing is performed on the transmission signal of the first time slot. When the scheduling type information indicates that the first time slot is not scheduled, the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot.

[0202] This design can achieve the scenario where there is no scheduling for the uplink time slot or downlink time slot, that is, there is no business data to be transmitted, and the scheduling type information can be used to indicate to the second network device that the uplink time slot or downlink time slot is not scheduled, and the beam identification information can be used to indicate to the second network device that beam weighting processing is not performed on the transmission signal of the first time slot; for the scenario where the uplink time slot or downlink time slot is scheduled, that is, there is business data to be transmitted, the scheduling type information can be used to indicate to the second network device that the uplink time slot or downlink time slot is scheduled, and the beam identification information can be used to indicate to the second network device that beam weighting processing is performed on the transmission signal of the first time slot; thereby, in the scenario where there is no business data to be transmitted, energy consumption can be reduced by not performing beam weighting processing. In this design, when the first network device decides whether to perform beam weighting processing on the transmission signal of the first time slot as indicated by the beam identification information, it only needs to make a decision based on the indication of the scheduling type information, without paying attention to the specific scheduling content of the first time slot.

[0203] For the second network device, the received first message includes scheduling type information and beam identification information. The second network device may not perform beam weighted processing on the transmission signal of the first time slot only when the scheduling type information indicates that the first time slot is not scheduled and the beam identification information indicates that the transmission signal of the first time slot is not subjected to beam weighted processing. For other situations, such as when the scheduling type information indicates that the first time slot is not scheduled and the beam identification information indicates that the transmission signal of the first time slot is subjected to beam weighted processing, or when the scheduling type information indicates that the first time slot is scheduled and the beam identification information indicates that the transmission signal of the first time slot is not subjected to beam weighted processing, etc., the second network device may perform beam weighted processing on the transmission signal of the first time slot, which may reduce the possibility of affecting the quality of UE service data transmission due to errors in the scheduling type information and beam identification information. The second network device may know that beam weighted processing is not performed on the transmission signal of the first time slot because the scheduling result of the first time slot is empty.

[0204] In one possible design, when the first message is sent through the communication interface between the first network device and the second network device, the first message may include a control plane message between the first network device and the second network device.

[0205] The control plane message may include resource information, and the resource information may be used to indicate the time slot resources of the first time slot. The control plane message may be used to indicate that the time slot resources of the first time slot have been scheduled.

[0206] For example, taking the scenario where there is no scheduling in the first time slot as an example, Fig.10 FIG. 2 shows another flow chart of the communication method provided in the embodiment of the present application. Fig.10 As shown, the communication method may include S1001-S1003.

[0207] S1001. A first network device schedules time slot resources of a first time slot.

[0208] S1001 may refer to the above-mentioned S401, S701-S702, etc., and will not be repeated here.

[0209] S1002. The first network device sends a control plane message to the second network device, where the control plane message includes resource information, beam identification information, and scheduling type information, where the resource information indicates the time slot resources of the first time slot, the scheduling type information indicates that the first time slot is not scheduled, and the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot.

[0210] Accordingly, the second network device receives the control plane message.

[0211] Exemplarily, the control plane message may be a scheduling and beamforming commands message. In the scheduling and beamforming commands message, the scheduling type information may be a "section type" field, and the beam identification information may be a "beamID" field. In a scenario where the first time slot is not scheduled, the "section type" field may indicate that the first time slot is not scheduled, and the "beamID" field may indicate that beam weighting processing is not performed on the transmission signal of the first time slot.

[0212] The resource information can be used to indicate which time slot the time slot resource of the first time slot is, and the second network device can know which time slot to transmit the signal to the UE according to the indication of the resource information.

[0213] In a possible implementation, when the value of the "section type" field is 0, it indicates that the first time slot is not scheduled; when the value of the "beamID" field is 0, it indicates that beam weighting processing is not performed on the transmission signal of the first time slot.

[0214] Optionally, in some other implementations, when the value of the "section type" field is other values, it indicates that the first time slot is not scheduled; when the value of the "beamID" field is other values, it indicates that beam weighting processing is not performed on the transmission signal of the first time slot. This application is not limited here.

[0215] S1003. The second network device does not perform beam weighting processing on the transmission signal of the first time slot.

[0216] S1003 may refer to the above-mentioned S403, which will not be described in detail here.

[0217] above Fig.10The illustrated embodiment shows an implementation method in which the first message is a control plane message in a scenario where the first time slot is not scheduled. The first time slot can be an uplink time slot or a downlink time slot. For a scenario where the first time slot is scheduled, when the first time slot is a downlink time slot, the first network device also needs to send downlink data to the second network device; when the first time slot is an uplink time slot, after the second network device receives the uplink data, it also needs to send uplink data to the first network device. Fig.11 and Fig.12 , continuing to take the first message as a control plane message as an example, the scenarios in which the downlink time slot is scheduled and the uplink time slot is scheduled are explained respectively.

[0218] Exemplarily, taking the scenario where the first time slot is a downlink time slot and there is scheduling as an example, Fig.11 FIG. 2 shows another flow chart of the communication method provided in the embodiment of the present application. Fig.11 As shown, the communication method may include S1101 - S1104 .

[0219] S1101. A first network device schedules time slot resources of a first time slot.

[0220] S1101 may refer to the above-mentioned S401, S701-S702, etc., and will not be repeated here.

[0221] S1102. The first network device sends a control plane message to the second network device. The control plane message includes resource information, beam identification information and scheduling type information. The resource information indicates the time slot resources of the first time slot, the scheduling type information indicates that the first time slot is scheduled, and the beam identification information indicates that beam weighted processing is performed on the transmission signal of the first time slot.

[0222] Accordingly, the second network device receives the control plane message.

[0223] Exemplarily, the control plane message is a scheduling and beamforming commands message, the scheduling type information is a "section type" field, and the beam identification information is a "beamID" field. When the value of the "section type" field is not 0, it indicates that the first time slot is scheduled; when the value of the "beamID" field is not 0, it indicates that beam weighting processing is performed on the transmission signal of the first time slot. The scheduling and beamforming commands message is used to indicate that the scheduling of the first time slot has been completed.

[0224] After the first network device sends the control plane message to the second network device, S1103 may also be executed.

[0225] S1103. The first network device sends downlink data to the second network device.

[0226] Correspondingly, the second network device receives the downlink data.

[0227] The downlink data may be service data that needs to be sent to the UE in the first time slot through the second network device. After receiving the downlink data, the second network device may send the downlink data to the UE in the first time slot according to the indication of the resource information. When sending data to the UE, the second network device may execute S1104 to perform beam weighting processing on the transmission signal of the first time slot.

[0228] S1104. The second network device performs beam weighting processing on the transmission signal of the first time slot.

[0229] S1104 may refer to the above-mentioned S603, which will not be described in detail here.

[0230] Exemplarily, taking the scenario where the first time slot is an uplink time slot and is scheduled as an example, Fig.12 FIG. 2 shows another flow chart of the communication method provided in the embodiment of the present application. Fig.12 As shown, the communication method may include S1201-S1204.

[0231] S1201. A first network device schedules time slot resources of a first time slot.

[0232] S1201 may refer to the above-mentioned S401, S701-S702, etc., and will not be repeated here.

[0233] S1202. The first network device sends a control plane message to the second network device. The control plane message includes resource information, beam identification information and scheduling type information. The resource information indicates the time slot resources of the first time slot, the scheduling type information indicates that the first time slot is scheduled, and the beam identification information indicates that beam weighted processing is performed on the transmission signal of the first time slot.

[0234] Accordingly, the second network device receives the control plane message.

[0235] S1202 may refer to the above-mentioned S1102 and will not be described in detail herein.

[0236] S1203. The second network device performs beam weighting processing on the transmission signal of the first time slot.

[0237] For example, Fig.12In the process shown, the control plane message can indicate to the second network device that there is uplink data of the UE to be received in the first time slot, and the second network device can receive the uplink data of the UE in the first time slot according to the indication of the resource information. When receiving the uplink data of the UE, the second network device can perform beam weighting processing on the transmission signal of the first time slot. S1203 can be specifically referred to as described in S603 above, and will not be repeated here.

[0238] The second network device may further execute S1204.

[0239] S1204. The second network device sends uplink data to the first network device.

[0240] Correspondingly, the first network device receives the uplink data.

[0241] For example, taking the first network device as O-DU and the second network device as O-RU as an example, for the above Figure 10-12 In the embodiment shown, in a specific implementation, the O-DU may schedule the time slot resources of the first time slot, and the time slot resources of the first time slot are used to transmit signals between the first network device and the second network device and the UE, such as transmitting service data. The scheduling result of the first time slot may include scheduling or no scheduling.

[0242] For the scenario where the first time slot is a downlink time slot, when there is no downlink data to be sent, the first time slot is not scheduled (the scheduling result is empty), and the O-DU will not send downlink data to the O-RU to avoid unnecessary signal transmission and resource waste. The O-DU can send a control plane message to the O-RU, notifying the O-RU in the control plane message that there is no downlink data to be sent in the first time slot. The specific notification method is to indicate that there is no scheduling in the first time slot through the scheduling type information in the control plane message. At the same time, the beam identification information can also be used in the control plane message to indicate that beam weighting processing is not performed on the transmission signal of the first time slot. The O-RU can not perform beam weighting processing on the transmission signal of the first time slot according to the instruction.

[0243] When there is downlink data that needs to be sent, and the first time slot is scheduled (the scheduling result is not empty), the O-DU can send a control plane message to the O-RU, and notify the O-RU in the control plane message that there is downlink data to be sent in the first time slot. The specific notification method is to indicate that the first time slot is scheduled through the scheduling type information in the control plane message. At the same time, the beam identification information can also be used in the control plane message to indicate that beam weighting processing is performed on the transmission signal of the first time slot. After that, the O-DU can send downlink data to the O-RU. According to the instruction, the O-RU can send downlink data to the UE through the wireless channel in the first time slot, and perform beam weighting processing on the transmission signal of the first time slot.

[0244] For the scenario where the first time slot is an uplink time slot, when there is no uplink data to be sent, the first time slot is not scheduled (the scheduling result is empty), and the O-DU can send a control plane message to the O-RU, notifying the O-RU in the control plane message that there is no uplink data to be received in the first time slot. The specific notification method is to indicate that the first time slot is scheduled through the scheduling type information in the control plane message. At the same time, the beam identification information can also be used in the control plane message to indicate that the transmission signal of the first time slot is not to be beam-weighted. According to the instruction, the O-RU does not perform beam-weighted processing on the transmission signal of the first time slot.

[0245] When there is uplink data that needs to be sent, and the first time slot is scheduled (the scheduling result is not empty), the O-DU can send a control plane message to the O-RU, and notify the O-RU in the control plane message that there is uplink data to be received in the first time slot. The specific notification method is to indicate that the first time slot is scheduled through the scheduling type information in the control plane message. At the same time, the beam identification information can also be used in the control plane message to indicate that the transmission signal of the first time slot is to be beam-weighted. According to the indication, the O-RU can receive the uplink data sent by the UE through the wireless channel in the first time slot, and perform beam-weighted processing on the transmission signal of the first time slot. After that, the O-RU can send uplink data to the O-DU.

[0246] In this design, the first message may be a control plane message sent through the network communication interface between the first network device and the second network device, such as a scheduling and beamforming commands message. Taking the scheduling and beamforming commands message as an example, there is indication information in the scheduling and beamforming commands message, which is used to indicate whether the second network device performs beam weighting processing. In a specific implementation, the indication information is a "section type" field and a "beamID" field. When the value of the "section type" field is not 0, it indicates that the first time slot is scheduled; when the value of the "beamID" field is not 0, it indicates that beam weighting processing is performed on the transmission signal of the first time slot.

[0247] This design can utilize existing control plane messages and add beam identification information to the control plane information to implement the function of instructing the second network device whether to perform beam weighted processing on the transmission signal of the first time slot. The implementation cost is low, such as low protocol modification cost.

[0248] In a possible design, the first message described in the above embodiment may also include at least one of the following identification information: compression identification information, filtering identification information, and symbol shutdown identification information.

[0249] The compression identification information is used to indicate whether to decompress or compress the in-phase and quadrature phase signals of the transmission signal of the first time slot. The filtering identification information is used to indicate whether to filter the transmission signal of the first time slot. The symbol shutoff identification information is used to indicate whether to shut off the symbol of the transmission signal of the first time slot.

[0250] After receiving the first message, the second network device can also process the transmission signal of the first time slot according to the instructions of the target identification information based on at least one target identification information among the compression identification information, filtering identification information, and symbol shutdown identification information included in the first message (for example, the compression identification information, filtering identification information, and symbol shutdown identification information in the first message can all be used as target identification information).

[0251] For example, the second network device may decompress or compress the in-phase and quadrature phase signals of the transmission signal of the first time slot according to the indication of the compression identification information, or may not decompress or compress the in-phase and quadrature phase signals of the transmission signal of the first time slot. For another example, the second network device may filter the transmission signal of the first time slot according to the indication of the filtering identification information, or may not filter the transmission signal of the first time slot. For another example, the second network device may perform symbol shutoff on the transmission signal of the first time slot according to the indication of the symbol shutoff identification information, or may not perform symbol shutoff on the transmission signal of the first time slot.

[0252] Exemplarily, the first message further includes compression identification information, filtering identification information, and symbol shutoff identification information, the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot, the compression identification information indicates that the in-phase and quadrature phase signals of the transmission signal of the first time slot are not decompressed or compressed, the filtering identification information indicates that the transmission signal of the first time slot is not filtered, and the symbol shutoff identification information indicates that the symbol of the transmission signal of the first time slot is shut off. Fig.13 FIG. 2 shows another flow chart of the communication method provided in the embodiment of the present application. Fig.13 As shown, the communication method may include S1301-S1303.

[0253] S1301. A first network device schedules time slot resources of a first time slot.

[0254] S1301 may refer to the above-mentioned S401, S701-S702, etc., and will not be repeated here.

[0255] S1302. The first network device sends a first message to the second network device, where the first message includes beam identification information, compression identification information, filtering identification information, and symbol shutoff identification information. The beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot, the compression identification information indicates that in-phase and quadrature-phase signals are not decompressed or compressed on the transmission signal of the first time slot, the filtering identification information indicates that filtering is not performed on the transmission signal of the first time slot, and the symbol shutoff identification information indicates that symbols of the transmission signal of the first time slot are shut off.

[0256] Accordingly, the second network device receives the first message.

[0257] S1303: The second network device performs symbol shutoff on the transmission signal of the first time slot, and does not perform the following processing on the transmission signal of the first time slot: beam weighting processing, in-phase and quadrature-phase signal decompression or compression, and filtering.

[0258] Exemplarily, when the first time slot is a downlink time slot, the compression identification information may indicate that the in-phase and quadrature-phase signals of the transmission signal of the first time slot are not decompressed; when the first time slot is an uplink time slot, the compression identification information may indicate that the in-phase and quadrature-phase signals of the transmission signal of the first time slot are not compressed.

[0259] The in-phase and quadrature-phase signals are the IQ signals described in the aforementioned embodiments. When the first network device does not compress the IQ signal, the compression identification information may indicate that the IQ signal is not decompressed for the transmission signal of the first time slot. The second network device does not decompress or compress the IQ signal for the transmission signal of the first time slot, which may include: the second network device turns off the digital signal processor (digital signal processor, DSP) used to implement the IQ signal decompression or compression function in the first time slot, or does not perform the step of decompressing or compressing the IQ signal by the digital signal processor. Optionally, the digital signal processor used to implement the IQ signal decompression or compression function may be a dedicated processor for implementing IQ signal decompression or compression processing. The processor may also be a field programmable gate array (field programmable gate array, FPGA) or other chips.

[0260] The second network device does not filter the transmission signal of the first time slot, which may include: turning off the filter of the RF front end in the first time slot, not executing the filtering function in the intermediate frequency processor, etc.

[0261] The second network device shuts down the symbol of the transmission signal of the first time slot, which may include: shutting down the power amplifier of the radio frequency module within the symbol period of the first time slot. Wherein, shutting down the power amplifier within the symbol period of the first time slot may refer to shutting down the power amplifier within the symbol period for the control signal, data channel, etc. in the first time slot.

[0262] When the first time slot is an uplink time slot, the power amplifier device that is turned off may be an uplink low noise amplifier (LNA); when the first time slot is a downlink time slot, the power amplifier device that is turned off may be a downlink PA.

[0263] Optionally, the power amplifier device may be turned off in a symbol-level or time slot-level manner. Symbol-level turning off means that the second network device may turn off the symbol in units of OFDM symbols. Time slot-level turning off means that the second network device may turn off the symbol in units of time slots. No limitation is made here.

[0264] The above introduces the situation where the compression identification information indicates that the in-phase and quadrature-phase signals of the transmission signal of the first time slot are not decompressed or compressed, the filtering identification information indicates that the transmission signal of the first time slot is not filtered, and the symbol-off identification information indicates that the symbol of the transmission signal of the first time slot is turned off. It can be understood that when the compression identification information, the filtering identification information, and the symbol-off identification information indicate other situations, the implementation method is similar to this and will not be repeated here.

[0265] In this design, the second network device does not decompress or compress the in-phase and quadrature phase signals of the transmission signal of the first time slot according to the instruction of the compression identification information, or does not filter the transmission signal of the first time slot according to the instruction of the filtering identification information, or performs symbol shutoff on the transmission signal of the first time slot according to the instruction of the symbol shutoff identification information, which can further reduce the energy consumption of the second network device. In addition, by indicating in the first message whether the second network device performs symbol shutoff on the transmission signal of the first time slot, the second network device does not need to decide whether to perform symbol shutoff on the transmission signal of the first time slot according to the symbol energy detection method, such as: the intermediate frequency chip of the second network device does not need to perform symbol energy detection, and the second network device only needs to perform symbol shutoff according to the instruction of the compression identification information.

[0266] In one possible design, the first network device may also decide, based on the scheduling result of the first time slot, whether to decompress or compress the in-phase and quadrature-phase signals of the transmission signal of the first time slot using compression identification information indicating whether to filter the transmission signal of the first time slot using filtering identification information indicating whether to perform symbol shutoff on the transmission signal of the first time slot using symbol shutoff identification information indicating whether to perform symbol shutoff on the transmission signal of the first time slot.

[0267] For example, when the first time slot is not scheduled, the compression identification information indicates that the in-phase and quadrature-phase signals of the transmission signal of the first time slot are not decompressed or compressed, the filtering identification information indicates that the transmission signal of the first time slot is not filtered, and the symbol-off identification information indicates that the symbol of the transmission signal of the first time slot is off.

[0268] When the first time slot is scheduled, the compression identification information indicates that the in-phase and quadrature-phase signals of the transmission signal of the first time slot are decompressed or compressed, the filtering identification information indicates that the transmission signal of the first time slot is filtered, and the symbol shutoff identification information indicates that the symbol of the transmission signal of the first time slot is not shutoff.

[0269] Among them, the method for judging whether the first time slot is scheduled can refer to the method described in the above-mentioned embodiment, such as determining whether the first time slot is scheduled according to scheduling information or scheduling type information, which will not be repeated here.

[0270] In the present design, the first network device determines, based on the scheduling result of the first time slot, whether to perform in-phase and quadrature-phase signal decompression or compression on the transmission signal of the first time slot, the filtering identification information indicates whether to filter the transmission signal of the first time slot, and the symbol-off identification information indicates whether to perform symbol-off on the transmission signal of the first time slot. This can achieve the scenario where there is no scheduling in the uplink time slot or the downlink time slot, that is, there is no business data to be transmitted, and instruct the second network device to perform symbol-off on the transmission signal of the first time slot, and not perform the following processing on the transmission signal of the first time slot: beam weighting processing, in-phase and quadrature-phase signal decompression or compression, and filtering. This can further reduce energy consumption by not decompressing or compressing the in-phase and quadrature-phase signal of the transmission signal of the first time slot, not filtering the transmission signal of the first time slot, and performing symbol-off on the transmission signal of the first time slot in the scenario where there is no business data to be transmitted, thereby saving energy consumption for the network device without affecting the quality of business data transmission.

[0271] Optionally, the implementation of the above-mentioned compression identification information, filtering identification information, symbol shutdown identification information and other identification information can refer to the implementation of the beam identification information described in the aforementioned embodiment, and is not limited here.

[0272] In some other embodiments, when the first time slot is scheduled (see above for details), the first network device may also instruct the second network device to process the transmission signal of the first time slot in at least one of the following ways: not performing beam weighting, not decompressing or compressing the in-phase and quadrature phase signals of the transmission signal of the first time slot, not filtering the transmission signal of the first time slot, and performing symbol shutoff on the transmission signal of the first time slot, which can be achieved in the scenario where the first time slot is scheduled, and can also reduce the energy consumption of the device, and this application does not limit this. Among them, the indication method can refer to the indication information in the aforementioned embodiment, and will not be repeated.

[0273] Optionally, in some other possible designs, the second network device may be instructed in the first message to shut down more RF module components to obtain more energy saving benefits. The instruction method may refer to the above embodiments of the present application, and the present application does not limit this.

[0274] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of interaction between various network elements. It can be understood that each network element, such as the first network device, the second network device, etc., in order to implement the above functions, includes a hardware structure and / or software module corresponding to each function.

[0275] For example: The embodiment of the present application may also provide a communication device that can be applied to the above-mentioned first network device.

[0276] like Fig.14 As shown, the communication device may include: a processing unit 1401 and a sending unit 1402.

[0277] The processing unit 1401 is used to schedule the time slot resources of the first time slot, and the time slot resources of the first time slot are used to transmit signals between the network device and the terminal device. The sending unit 1402 is used to send a first message, and the first message includes beam identification information, and the beam identification information is used to indicate whether to perform beam weighting processing on the transmission signal of the first time slot.

[0278] In a possible design, the processing unit 1401 is further used to obtain scheduling information, where the scheduling information is used to indicate whether the first time slot is scheduled. When the scheduling information indicates that the first time slot is not scheduled, the beam identification information indicates that the transmission signal of the first time slot is not subjected to beam weighting processing.

[0279] In one possible design, the first message further includes scheduling type information; the scheduling type information is used to indicate whether the first time slot is scheduled.

[0280] In one possible design, the first message includes a control plane message, the control plane message includes resource information, the resource information is used to indicate the time slot resources of the first time slot, and the control plane message is used to indicate that the time slot resources of the first time slot have been scheduled.

[0281] In a possible design, the first message further includes at least one of the following identification information: compression identification information, filtering identification information, and symbol shutoff identification information. The compression identification information is used to indicate whether to perform in-phase and quadrature phase signal decompression or compression on the transmission signal of the first time slot; the filtering identification information is used to indicate whether to perform filtering on the transmission signal of the first time slot; and the symbol shutoff identification information is used to indicate whether to perform symbol shutoff on the transmission signal of the first time slot.

[0283] In one possible design, the first time slot includes an uplink time slot and / or a downlink time slot.

[0284] Optionally, the above Fig.14 The communication device shown may also include a receiving unit (not shown in the figure) for implementing a receiving function, such as receiving information (such as uplink data) from the second network device or other network devices.

[0285] For another example: The embodiment of the present application may also provide a communication device that can be applied to the above-mentioned second network device. Fig.15 Another structural schematic diagram of a communication device provided in an embodiment of the present application is shown.

[0286] like Fig.15 As shown, the communication device may include: a receiving unit 1501 and a processing unit 1502.

[0287] The receiving unit 1501 is used to receive a first message, the first message includes beam identification information, and the beam identification information is used to indicate whether to perform beam weighting processing on the transmission signal of the first time slot. The processing unit 1502 is used to not perform beam weighting processing on the transmission signal of the first time slot when the beam identification information indicates no.

[0288] In one possible design, the first message further includes scheduling type information; the scheduling type information is used to indicate whether the first time slot is scheduled. When the scheduling type information indicates that the first time slot is not scheduled, the beam identification information indicates that beam weighting processing is not performed on the transmission signal of the first time slot.

[0289] In one possible design, the first message includes a control plane message, the control plane message includes resource information, the resource information is used to indicate the time slot resources of the first time slot, and the control plane message is used to indicate that the time slot resources of the first time slot have been scheduled.

[0290] In a possible design, the first message further includes at least one of the following identification information: compression identification information, filtering identification information, and symbol shutoff identification information. The compression identification information is used to indicate whether to perform in-phase and quadrature phase signal decompression or compression on the transmission signal of the first time slot; the filtering identification information is used to indicate whether to perform filtering on the transmission signal of the first time slot; and the symbol shutoff identification information is used to indicate whether to perform symbol shutoff on the transmission signal of the first time slot.

[0291] The processing unit 1502 is further configured to process the transmission signal of the first time slot according to the instruction of at least one target identification information among the compression identification information, the filtering identification information and the symbol off identification information.

[0292] In one possible design, when the first time slot is not scheduled, the compression identification information indicates that the in-phase and quadrature-phase signals of the transmission signal of the first time slot are not decompressed or compressed, the filtering identification information indicates that the transmission signal of the first time slot is not filtered, and the symbol-off identification information indicates that the symbol of the transmission signal of the first time slot is off.

[0293] In one possible design, the first time slot includes an uplink time slot and / or a downlink time slot.

[0295] It should be understood that the division of units in the above device is only a division of logical functions. In actual implementation, they can be fully or partially integrated into one physical entity, or physically separated. Moreover, the units in the device can be all implemented in the form of software calling through processing elements; or all implemented in the form of hardware; or some units can be implemented in the form of software calling through processing elements, and some units can be implemented in the form of hardware.

[0296] For example, each unit can be a separately established processing element, or it can be integrated in a certain chip of the device. In addition, it can also be stored in a memory in the form of a program, and called and executed by a certain processing element of the device. In addition, all or part of these units can be integrated together, or they can be implemented independently.

The storage element may be a storage element on the same chip as the processing element, that is, an on-chip storage element.

[0304] In another implementation, the program for executing the method executed by the first network device or the second network device in the above method can be in a storage element on a different chip from the processing element, that is, an off-chip storage element. In this case, the processing element calls or loads the program from the off-chip storage element to the on-chip storage element to call and execute the method executed by the first network device or the second network device in the above method embodiment.

These integrated circuits may be integrated together to form a chip.

[0307] The units of the first network device or the second network device that implement each step in the above method can be integrated together and implemented in the form of a SOC, and the SOC chip is used to implement the corresponding method. The chip can integrate at least one processing element and a storage element, and the corresponding method is implemented in the form of a program stored in the storage element by the processing element; or, the chip can integrate at least one integrated circuit to implement the corresponding method; or, the above implementation methods can be combined, and the functions of some units are implemented in the form of a processing element calling a program, and the functions of some units are implemented in the form of an integrated circuit.
