Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a forwarding power control method, apparatus, forwarding node, and network-side equipment. Background Art

[0002] Network Controlled Repeater (NCR) nodes are usually used to expand the coverage of a cell. They can not only be used to receive, amplify and forward downlink signals from upstream base stations to increase the signal strength reaching user equipment (UE), but can also be used to receive, amplify and forward uplink signals from UE to increase the strength of uplink signals reaching the base station. The UE can control the transmit power of the UE transmitter (uplink) through the closed-loop power control mechanism of the wireless link between the UE and the base station. Similarly, the base station can also control the transmit power of the base station transmitter (downlink) through the closed-loop power control mechanism of the wireless link between the base station and the UE. Among them, the closed-loop power control mechanism refers to the transmitter (such as a base station) adjusting its transmit power according to the signal feedback from the receiver (such as a UE).

[0003] For a communication system deployed with NCR nodes, if only a closed-loop power control mechanism is used to adjust the transmit power of the UE and the base station without controlling the forwarding power of the NCR node, it is possible that the transmit power adjusted by the UE or the base station using the closed-loop power control mechanism will not achieve the desired effect, that is, the strength of the received signal of the terminal and the network side device cannot be guaranteed, thereby reducing the signal transmission quality between the network side device and the terminal.

[0004] However, since the closed-loop power control mechanism used to control the transmit power of a UE or a base station is not suitable for controlling the forwarding power of an NCR node, there is an urgent need in the art for a forwarding power control method capable of controlling the forwarding power of an NCR node.

[0059] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0060] The terms "first", "second", etc. of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the present application are implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or at least two. In addition, "or" in the present application represents at least one of the connected objects.

A direct indication can be understood as the sender explicitly informing the receiver of specific information, operations to be performed, or request results, etc. in the indication sent; an indirect indication can be understood as the receiver determining the corresponding information based on the indication sent by the sender, or making a judgment and determining the operations to be performed or request results, etc. based on the judgment result.

[0062] It is worth noting that the systems to which the technical solutions provided in the present application are applicable include, but are not limited to, Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, and can also be used for other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) or other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described techniques can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and NR terminology is used in most of the following descriptions, but these techniques can also be applied to systems other than NR systems, such as the 6th generation (6 th Generation, 6G) communication system.

[0063] Figure 1 It is a block diagram of a wireless communication system 100 that can be applied in the embodiments of the present application.

[0064] like Figure 1 As shown, the wireless communication system includes a terminal 110 , a network side device 120 and a forwarding node 130 .

[0065] Among them, the terminal 110 can be a mobile phone, a tablet personal computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device (Wearable Device), a flight vehicle, a vehicle user equipment (VUE), a ship-borne equipment, a pedestrian terminal (Pedestrian User Equipment, PUE), a smart home (home appliances with wireless communication functions, such as refrigerators, televisions, washing machines or furniture, etc.), a game console, a personal computer (PC), a teller machine or a self-service machine and other terminal side devices. Wearable devices include: smart watches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. Among them, the vehicle-mounted device can also be called a vehicle-mounted terminal, a vehicle-mounted controller, a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip or a vehicle-mounted unit, etc. It should be noted that the specific type of the terminal 110 is not limited in the embodiment of the present application.

[0066] The network side device 120 may include an access network device or a core network device, wherein the access network device may also be referred to as a radio access network (RAN) device, a radio access network function or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AS) or a wireless fidelity (WiFi) node, etc. Among them, the base station can be called Node B (Node B, NB), Evolved Node B (Evolved Node B, eNB), the next generation Node B (the next generation Node B, gNB), New Radio Node B (New Radio Node B, NR Node B), access point, Relay Base Station (Relay Base Station, RBS), Serving Base Station (Serving Base Station, SBS), Base Transceiver Station (Base Transceiver Station, BTS), Radio Base Station, Radio Transceiver, Basic Service Set (Basic Service Set, BSS), Extended Service Set (Extended Service Set, ESS), Home Node B (home Node B, HNB), Home Evolved Node B (home evolved Node B), Transmission Reception Point (Transmission Reception Point, TRP) or other appropriate terms in the field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0067] The main function of the forwarding node 130 is to receive and forward signals between the terminal 110 and the network-side device 120 .

[0068] In addition, the forwarding node 130 can also be used to expand the coverage of the cell. It can not only be used to receive, amplify and forward the downlink signal from the network side device 120, so that the signal strength reaching the terminal 110 is increased, but also can be used to receive, amplify and forward the uplink signal from the terminal 110, so that the strength of the uplink signal reaching the network side device 120 is increased. The forwarding node can be implemented as a variety of devices, depending on the network architecture and requirements. For example, the forwarding node 130 may include: a network controlled repeater (NCR) node, a wireless node that can amplify the power of the input signal and forward it by reflection or refraction, a hub, a switch, a router, a gateway or a wireless access point, etc. These types of devices can be used alone or in combination to achieve specific network requirements. The specific implementation of the forwarding node 130 depends on factors such as the network architecture, performance requirements, and security policies, and this application does not specifically limit this.

[0069] Among them, a hub is a simple network device that can bring together data signals from multiple nodes and transmit them to other nodes. Hubs are often used in shared networks, such as Ethernet, and have simple forwarding functions. A switch is a smarter network device that can determine the best forwarding path based on the source and destination addresses of the data packet and provide more efficient communication. A router is a complex network device that can determine the forwarding path of the data packet based on the routing table and send it to the destination address. Routers are often used in scenarios such as Internet access, enterprise networks, and virtual private networks (VPNs) to achieve interconnection between different networks. A gateway is a device used to connect different networks or protocols. It can convert data packets from one protocol to another for communication between different networks. For example, a wide area network (WAN) gateway can convert local area network (LAN) data packets into a format suitable for wide area network transmission. A wireless access point is a network device that provides wireless communication coverage and connects mobile devices to the network. It is usually configured to relay wireless signals so that mobile devices can communicate with the network core. A wireless access point can be considered as a forwarding node that processes and forwards wireless data packets.

[0070] It is worth noting that a base station can be regarded as a specific forwarding node, because a base station can receive data packets sent from a mobile device and forward them to other network nodes, or forward data packets from other network nodes to a mobile device. Therefore, in some specific scenarios, the forwarding node 130 can also be replaced by a base station or other access network devices.

[0071] The forwarding node 130 may include a device that can accept control from the network side device 120, that is, the network side device 120 can control the transmission parameters of the amplifier of the forwarding node 130, such as controlling the switch and transmission beam of the forwarding node, so as to improve the working efficiency of the amplifier and reduce interference.

[0072] like Figure 1 As shown, the forwarding node 130 is an active node, which includes a mobile terminal (MobileTermination, MT) module 131 and a forwarding (Forwarding, Fwd) module 132. For example, when the forwarding node 130 is an NCR node, the NCR node includes an NCR mobile terminal (NCR Mobile Termination, NCR-MT) module and an NCR forwarding module (NCR Forwarding, NCR-Fwd) module.

[0073] Among them, the MT module 131 can establish a connection with the network side device 120, and the network side device 120 exchanges side control information with the Fwd module 132 through the MT module 131, and the side control information can indicate the sending / receiving related parameters of the Fwd module 132 of the forwarding node 130. Specifically, there is a control link (Ctrl link) between the MT module 131 and the network side device 120, which is used to transmit the side control information, that is, the network side device 120 sends the side control information to the Fwd module 132 through the MT module 131, and then controls the forwarding behavior of the Fwd module 132. For example, the forwarding behavior of the Fwd module 132 is controlled by controlling the sending / receiving related parameters of the Fwd module 132 of the forwarding node, such as but not limited to uplink and downlink configurations, beam parameters, etc.

[0074] In addition, there is a backhaul link (BL) between the Fwd module 132 and the network side device 120 , and there is an access link (AL) between the Fwd module 132 and the terminal 110 , which is used to forward wireless signals between the network side device 120 and the terminal 110 .

[0075] In order to facilitate a better understanding of the embodiments of the present application, the technologies related to the present application are explained.

[0076] (1) UE uplink transmit power control mechanism

[0077] The uplink transmission of the UE to the network side device has a power control mechanism, which is used to control the uplink transmission power of the UE. The purpose of uplink power control is: by adjusting the uplink transmission power of the UE, the receiving power of the network side device reaches an appropriate level, thereby ensuring the strength of the received signal; at the same time, avoid the uplink transmission power of the UE being too large, thereby avoiding greater interference to neighboring cells and avoiding wasting the power of the UE. Specifically, the UE can determine the uplink transmission power based on at least one of the following calculations: the propagation path loss between the network side device and the UE, the occupied spectrum width, the modulation and coding scheme (MCS), the coding rate, the target receiving power level set by the network side device, the power adjustment amount configured by the network side device through the power control command, etc.

[0078] The downlink transmission of the network side device to the UE may or may not have a power control mechanism. Normally, no dynamic power adjustment is performed on the downlink transmission of the network side device to the UE. For example, the transmission power of the downlink transmission of the network side device to the UE can be implemented based on the performance of the network side device. In this case, the network side device can determine the downlink channel quality between the network side device and the UE and the size of the data block to be sent based on the UE's channel state information (CSI) report, allocate an appropriate amount of time-frequency resources and select appropriate transmission parameters (such as the number of spatial data streams, MCS, duration, frequency range), so that the amount of information transmitted matches the amount of allocated resources.

[0079] (2) Semi-static beam configuration and periodic beam configuration

[0080] The semi-static beam configuration is used to configure the beam indication of the semi-static resource, that is, to instruct the forwarding node to forward with the beam indicated by the beam indication on the semi-static resource. For example, the semi-static beam configuration may include the semi-static resources pre-configured by the network side device to the forwarding node and their corresponding beam parameters. The semi-static beam configuration can be carried in the Radio Resource Control (RRC) signaling and configured to the forwarding node. It is worth noting that after the network side device configures the semi-static beam configuration for the forwarding node, it is also necessary to use the Media Access Control (MAC) control element (CE) to activate or deactivate the forwarding of the forwarding node on the pre-configured semi-static resource with the corresponding beam. In addition, it also supports the network side device to update the corresponding beam parameters of the pre-configured semi-static resources through the MAC CE.

[0081] Figure 2 This is an example of a semi-static beam configuration provided according to an embodiment of the present application.

[0082] like Figure 2 As shown, the forwarding node receives the semi-static beam configuration sent by the network side device, and the semi-static beam configuration may include the semi-static resources preconfigured by the network side device to the forwarding node and its corresponding beam parameters. After receiving the semi-static beam configuration, the forwarding node may activate the forwarding of the corresponding beam on the pre-configured semi-static resource by receiving beam configuration activation indication information, and deactivate the forwarding of the corresponding beam on the pre-configured semi-static resource by receiving beam configuration deactivation indication information.

[0083] The periodic beam configuration is used to configure periodic beam indications, that is, to instruct the forwarding node to forward with the beam indicated by the beam indication on the periodic resources. For example, the periodic beam configuration may include the periodic resources and their corresponding beam parameters pre-configured by the network-side device to the forwarding node. The periodic beam configuration can be carried in the RRC signaling and configured to the forwarding node. The difference between the periodic beam configuration and the semi-static beam configuration is that after the forwarding node receives the periodic beam configuration, it takes effect immediately, and there is no need for the network-side device to use MAC CE to activate, deactivate or update the periodic beam configuration.

[0084] Figure 3 This is an example of a periodic beam configuration provided according to an embodiment of the present application.

[0085] like Figure 3As shown, the forwarding node receives the periodic beam configuration sent by the network side device, and the periodic beam configuration may include the periodic resources preconfigured by the network side device to the forwarding node and its corresponding beam parameters. The periodic beam configuration sent by the network side device takes effect immediately after the forwarding node receives it, that is, the forwarding node directly forwards on the preconfigured periodic resources with the corresponding beam parameters, until the forwarding node receives the release instruction for the periodic beam configuration, and the forwarding node may not forward on the preconfigured periodic resources with the corresponding beam parameters.

[0086] It should be noted that for a communication system deployed with a forwarding node, semi-static beam configuration and periodic beam configuration are usually used to control the beam used by the forwarding node when forwarding signals, but the forwarding power is not controlled.

[0087] However, if only the closed-loop power control mechanism is used to adjust the transmission power of the UE and the base station without controlling the forwarding power of the forwarding node, it is possible that the transmission power adjusted by the UE or the base station using the closed-loop power control mechanism will not achieve the desired effect, that is, the strength of the received signal of the terminal and the network side device cannot be guaranteed, thereby reducing the signal transmission quality between the network side device and the terminal.

[0088] Considering that the closed-loop power control applied to the wireless link between the UE and the base station is used to control the transmission power of the UE transmitter (uplink) or the base station transmitter (downlink), it is not suitable for controlling the forwarding power of the forwarding node. Therefore, the present application provides a forwarding power control method, in which the forwarding node receives at least one forwarding power control configuration sent by the network side device, and controls the forwarding power of the forwarding node based on the at least one forwarding power control configuration, and by controlling the forwarding power of the forwarding node, the purpose of adjusting the strength of the received signal of the terminal and the network side device can be achieved, thereby facilitating the improvement of the signal transmission quality between the network side device and the terminal.

[0089] In addition, usually, in order to avoid the problem of excessive side control signaling overhead caused by frequently sending beam indication instructions, the forwarding node supports semi-static beam configuration (i.e., beam indication for configuring semi-static resources) and periodic beam configuration (i.e., beam indication for configuring periodic resources), that is, the beam indication is configured with semi-static resources or periodic resources as the granularity, thereby controlling the beam used by the forwarding node when forwarding on periodic time-frequency resources. In this case, if the forwarding power of the forwarding node is controlled, it is necessary to control the forwarding power of each time-frequency resource involved in the semi-static beam configuration and the periodic beam configuration. If the forwarding power of each time-frequency resource involved in the semi-static beam configuration and the periodic beam configuration is dynamically indicated (i.e., dynamically indicated according to demand), it will not only bring a large control signaling overhead, but also require the forwarding node to frequently switch to the downlink receiving state to receive the forwarding power adjustment indication, which further increases the waste of resources.

[0090] In view of this, in this embodiment, on the basis of introducing the at least one forwarding power control configuration, since the at least one forwarding power control configuration includes at least one of the following: semi-static forwarding power control configuration, periodic forwarding power control configuration, it is possible to reduce the frequency of the forwarding node receiving the forwarding power control configuration, and thus on the basis of controlling the forwarding power of the forwarding node, reduce the signaling overhead and resource overhead of the forwarding node.

[0094] The forwarding power control method 200 may be interactively executed by a forwarding node and a network side device. The forwarding node may be any node that can amplify a signal and forward information (e.g., a forwarding node in a 5G or 6G system), or the forwarding node may be a node that can perform power control and is used to forward signals between a UE and a network side device. For example, the forwarding node may be an NCR node. The network side device may be any access network device. For example, Figure 4The forwarding node shown in can be Figure 1 The forwarding node 130 shown, Figure 4 The network devices shown in can be Figure 1 The network side device 120 is shown.

[0095] like Figure 4 As shown, the forwarding power control method 200 may include at least part of the following contents:

[0096] S210, the forwarding node receives at least one forwarding power control configuration sent by the network side device; wherein the at least one forwarding power control configuration includes at least one of the following: a semi-persistent forwarding power control configuration and a periodic forwarding power control configuration.

[0097] Exemplarily, the forwarding node may receive the at least one forwarding power control configuration sent by the network side device through RRC signaling, F1 interface-application protocol (F1-AP) signaling, operation and maintenance (OAM) information or other signaling.

[0098] Exemplarily, the at least one forwarding power control configuration may include only the semi-static forwarding power control configuration, or may include only the periodic forwarding power control configuration, or may include the semi-static forwarding power control configuration and the periodic forwarding power control configuration. Of course, the at least one forwarding power control configuration may also include a forwarding power control configuration other than the semi-static forwarding power control configuration and the periodic forwarding power control configuration. For example, the at least one forwarding power control configuration may also include a non-periodic forwarding power control configuration or other types of forwarding power control configurations, which is not specifically limited in the present application.

[0099] Exemplarily, the semi-static forwarding power control configuration is used to control the forwarding power of the forwarding node on the semi-static resource; the semi-static resource may be a resource configured in the semi-static forwarding power control configuration, or may be a pre-configured resource. The periodic forwarding power control configuration is used to control the forwarding power of the forwarding node on the periodic resource; the periodic resource may be a resource in the periodic forwarding power control configuration, or may be a pre-configured resource. Among them, the semi-static resource includes a periodic time domain resource, a frequency domain resource, or an air domain resource that is configured through RRC signaling and starts to be used after MAC CE activation. The periodic resource includes a periodic time domain resource, a frequency domain resource, or an air domain resource that can be used directly after being configured through RRC signaling. The difference between semi-static resources and periodic resources is that semi-static resources need to be configured first and then activated before they can be used, while periodic resources can be used directly after configuration without the need for additional activation steps. The common point between semi-static resources and periodic resources is that both semi-static resources and periodic resources are periodically configured resources. The periodic configuration resource may be a periodic resource configured by the network side device to the terminal. The periodic configuration resource includes but is not limited to: periodic time domain resources, periodic frequency domain resources, periodic space domain resources, periodic time-frequency resources, periodic time-space resources, periodic frequency-space resources, periodic time-frequency-space resources, etc.

[0100] S220: The forwarding node controls the forwarding power of the forwarding node based on the at least one forwarding power control configuration.

[0101] Exemplarily, the forwarding node may control the forwarding power of the downlink signal of the forwarding node based on the forwarding power control configuration in the at least one forwarding power control configuration.

[0102] For example, the forwarding power control configuration in the at least one forwarding power control configuration may include a forwarding power control configuration applicable to downlink signals. Accordingly, when the forwarding node amplifies and forwards the downlink signal from the network side device, the forwarding node can control the forwarding power used by the forwarding node when forwarding the downlink signal based on the corresponding forwarding power control configuration, thereby expanding the coverage range of the cell and increasing the signal strength reaching the terminal.

[0103] Exemplarily, the forwarding node may control the forwarding power of the uplink signal of the forwarding node based on the forwarding power control configuration in the at least one forwarding power control configuration.

[0104] For example, the forwarding power control configuration in the at least one forwarding power control configuration may include a forwarding power control configuration applicable to an uplink signal. Accordingly, when the forwarding node amplifies and forwards the uplink signal from the terminal, the forwarding node can control the forwarding power of the uplink signal of the forwarding node based on the corresponding forwarding power control configuration, thereby expanding the coverage range of the cell and increasing the strength of the uplink signal reaching the network side device.

[0105] For example, the forwarding power control configuration in the at least one forwarding power control configuration may include a configuration for an uplink signal, that is, when the forwarding node amplifies and forwards the uplink signal from the terminal, the forwarding power control configuration can be used to control the forwarding power used by the forwarding node when forwarding the uplink signal.

[0106] Exemplarily, the forwarding node may control the forwarding power of the downlink signal and the uplink signal of the forwarding node based on any one of the at least one forwarding power control configurations. In other words, the any one forwarding power control configuration is a forwarding power control configuration applicable to the downlink signal and the uplink signal.

[0107] Exemplarily, the forwarding power control configuration in the at least one forwarding power control configuration may be applicable to periodic configuration resources, or in other words, the forwarding node may control the forwarding power of the forwarding node on the periodic configuration resources based on the forwarding power control configuration in the at least one forwarding power control configuration, and the present application does not limit this. The periodic configuration resource may be a periodic resource configured by a network side device to a terminal. The periodic configuration resource includes, but is not limited to: periodic time domain resources, periodic frequency domain resources, periodic spatial domain resources, periodic time-frequency resources, periodic time-space resources, periodic frequency-space resources, periodic time-frequency-space resources, etc. For example, the forwarding power control configuration in the at least one forwarding power control configuration may be applicable to periodic time domain resources, may be applicable to periodic time-frequency resources, and may be applicable to periodic time-frequency-space resources. In other words, the forwarding node may control the forwarding power of the forwarding node on periodic time domain resources, periodic time-frequency resources, or periodic time-frequency-space resources based on the forwarding power control configuration in the at least one forwarding power control configuration.

[0108] It is worth noting that, from the perspective of whether activation is required, the periodic configuration resources can be further divided into semi-static resources and periodic resources.

[0109] That is to say, the forwarding power control configuration in the at least one forwarding power control configuration is applicable to semi-static resources or periodic resources, or the forwarding node can control the forwarding power of the forwarding node on the semi-static resources or periodic resources based on the forwarding power control configuration in the at least one forwarding power control configuration. For example, the semi-static forwarding power control configuration in the at least one forwarding power control configuration is applicable to semi-static resources, or the forwarding node can control the forwarding power of the forwarding node on the semi-static resources based on the semi-static forwarding power control configuration in the at least one forwarding power control configuration. For another example, the periodic forwarding power control configuration in the at least one forwarding power control configuration is applicable to periodic resources, or the forwarding node can control the forwarding power of the forwarding node on the periodic resources based on the periodic forwarding power in the at least one forwarding power control configuration.

[0110] Exemplarily, the forwarding node may control the forwarding power of the forwarding node on the periodic time domain resources based on the forwarding power control configuration in the at least one forwarding power control configuration.

[0111] For example, the forwarding power control configuration in the at least one forwarding power control configuration includes a periodic time domain resource and its corresponding forwarding power adjustment amount, so that the forwarding node can determine the forwarding power amplification factor of the forwarding node on the periodic time domain resource based on the forwarding power adjustment amount in the forwarding power control configuration, and then determine the forwarding power of the forwarding node on the periodic time domain resource based on the forwarding power amplification factor of the forwarding node on the periodic time domain resource. In other words, for the forwarding power control configuration in the at least one forwarding power control configuration, the forwarding power adjustment amount included in the configuration can be applicable to the periodic time domain resource determined by the time parameter in the forwarding power control configuration, and is applicable to all forwarding beams (i.e., not affected by the forwarding beam) and forwarding frequencies (i.e., not affected by the forwarding frequency).

[0112] It should be understood that in the present embodiment, when the forwarding node controls the forwarding power of the forwarding node, the purpose of determining the forwarding power amplification factor is to determine the forwarding power of the forwarding node. However, in other alternative embodiments, the forwarding power amplification factor may not be introduced, that is, the forwarding power of the forwarding node may be determined directly based on the forwarding power adjustment amount. The schemes related to the forwarding power amplification factor involved below may also be processed in a similar manner, and the present application does not make any specific limitations on this.

[0113] Exemplarily, the forwarding node may control the forwarding power of the forwarding node on the periodic time-frequency resources based on the forwarding power control configuration in the at least one forwarding power control configuration.

[0114] For example, the forwarding power control configuration in the at least one forwarding power control configuration includes a periodic time-frequency resource and its corresponding forwarding power adjustment amount, so that the forwarding node can determine the forwarding power amplification factor of the forwarding node on the periodic time-frequency resource based on the forwarding power adjustment amount in the forwarding power control configuration, and then determine the forwarding power of the forwarding node on the periodic time-frequency resource based on the forwarding power amplification factor of the forwarding node on the periodic time-frequency resource. In other words, for the forwarding power control configuration in the at least one forwarding power control configuration, the forwarding power adjustment amount included in the configuration can be applicable to the periodic time-frequency resource determined by the time parameter and frequency parameter in the forwarding power control configuration, and is applicable to all forwarding beams (i.e., not affected by the forwarding beam).

[0115] Exemplarily, the forwarding node may control the forwarding power of the forwarding node on the periodic spatiotemporal resources based on the forwarding power control configuration in the at least one forwarding power control configuration.

[0116] For example, the forwarding power control configuration in the at least one forwarding power control configuration includes a periodic spatiotemporal resource and its corresponding forwarding power adjustment amount, so that the forwarding node can determine the forwarding power amplification factor of the forwarding node on the periodic spatiotemporal resource based on the forwarding power adjustment amount in the forwarding power control configuration, and then determine the forwarding power of the forwarding node on the periodic spatiotemporal resource based on the forwarding power amplification factor of the forwarding node on the periodic spatiotemporal resource. In other words, for the forwarding power control configuration in the at least one forwarding power control configuration, the forwarding power adjustment amount included in the configuration can be applicable to the periodic spatiotemporal resource determined by the time parameter and beam parameter in the forwarding power control configuration, and is applicable to all forwarding frequencies (i.e., not affected by the forwarding frequency).

[0117] Exemplarily, the forwarding node may control the forwarding power of the forwarding node on the periodic time-frequency-space resources based on the forwarding power control configuration in the at least one forwarding power control configuration.

[0118] For example, the forwarding power control configuration in the at least one forwarding power control configuration includes periodic time-frequency-space resources and their corresponding forwarding power adjustment amounts, so that the forwarding node can determine the forwarding power amplification factor of the forwarding node on the periodic time-frequency-space resources based on the forwarding power adjustment amount in the forwarding power control configuration, and further determine the forwarding power of the forwarding node on the periodic time-frequency-space resources based on the forwarding power amplification factor of the forwarding node on the periodic time-frequency-space resources. In other words, for the forwarding power control configuration in the at least one forwarding power control configuration, the forwarding power adjustment amount included in the configuration can be applicable to the periodic time-frequency-space resources determined by the time parameters, frequency parameters and beam parameters in the forwarding power control configuration.

[0119] Exemplarily, the forwarding node may control the forwarding power of the forwarding node on the semi-static resources based on the semi-static forwarding power control configuration.

[0120] For example, the semi-static forwarding power control configuration is used to configure the forwarding power adjustment amount of the semi-static resource, that is, to instruct the forwarding node to forward on the semi-static resource with a forwarding power determined based on the forwarding power adjustment amount. For example, the semi-static forwarding power control configuration may include the semi-static resource pre-configured by the network side device to the forwarding node and the corresponding forwarding power adjustment amount. The semi-static forwarding power control configuration may be carried in the RRC signaling and configured to the forwarding node.

[0121] It is worth noting that after the network-side device configures the semi-static forwarding power control configuration for the forwarding node, it is also necessary to activate or deactivate the semi-static forwarding power control configuration through MACCE, that is, to activate or deactivate the forwarding of the forwarding node on the semi-static resource with the corresponding forwarding power (that is, the forwarding power determined based on the forwarding power adjustment amount in the semi-static forwarding power control configuration), or in other words, to activate or deactivate the forwarding power control of the forwarding node on the semi-static resource based on the semi-static forwarding power control configuration. In addition, for the semi-static resource, the forwarding node can also support the network-side device to update its corresponding forwarding power adjustment amount through MAC CE. In this case, the forwarding node forwards on the semi-static resource with the forwarding power determined based on the updated forwarding power adjustment amount; of course, the MACCE used to activate the semi-static forwarding power control configuration and the MACCE used to update the forwarding power adjustment amount can be the same MACCE or different MACCEs, and this application does not make specific limitations on this.

[0122] Exemplarily, the forwarding node may control the forwarding power of the forwarding node on the periodic resources based on the periodic forwarding power control configuration.

[0123] Exemplarily, the periodic forwarding power control configuration is used to configure the forwarding power adjustment amount of the periodic resource, that is, to instruct the forwarding node to forward on the periodic resource with a forwarding power determined based on the forwarding power adjustment amount. For example, the periodic forwarding power control configuration may include the periodic resources and their corresponding forwarding power parameters pre-configured by the network side device to the forwarding node. The periodic forwarding power control configuration can be carried in the RRC signaling and configured to the forwarding node. The difference between the periodic forwarding power control configuration and the semi-static forwarding power control configuration is that after the forwarding node receives the periodic forwarding power control configuration, it takes effect immediately, and there is no need for the network side device to use MAC CE to activate, deactivate or update the periodic forwarding power control configuration.

[0124] It should be understood that in other alternative embodiments, the semi-persistent forwarding power control configuration or the periodic forwarding power control configuration may also be equivalently replaced by other terms with similar meanings, and the present application does not limit this. For example, when the semi-persistent forwarding power control configuration carries an adjustment amount for the forwarding power, it may also be referred to as a semi-persistent forwarding power adjustment configuration; similarly, when the periodic forwarding power control configuration carries an adjustment amount for the forwarding power, it may also be referred to as a periodic forwarding power adjustment configuration.

[0125] In this embodiment, the forwarding node receives at least one forwarding power control configuration sent by the network side device, and controls the forwarding power of the forwarding node based on the at least one forwarding power control configuration. By controlling the forwarding power of the forwarding node, the strength of the received signal of the terminal and the network side device can be adjusted, thereby improving the signal transmission quality between the network side device and the terminal. Further, the at least one forwarding power control configuration includes at least one of the following: a semi-static forwarding power control configuration and a periodic forwarding power control configuration, which can reduce the signaling overhead and resource overhead of the forwarding node on the basis of controlling the forwarding power of the forwarding node.

[0126] It should be noted that by controlling the forwarding power of the forwarding node, the strength of the received signal of the terminal and the network side device can be controlled, which can also reduce the difficulty of the UE and the network side device in controlling the transmission power, thereby improving the universality of the forwarding node.

[0127] In some embodiments, the at least one forwarding power control configuration includes the semi-static forwarding power control configuration, and the semi-static forwarding power control configuration includes: a semi-static resource list, and a forwarding power adjustment amount corresponding to each semi-static resource in the semi-static resource list; wherein, S220 may include: the forwarding node receives activation indication information sent by the network side device, and the activation indication information is used to indicate activation (also referred to as start-up) or reactivation (also referred to as restart) of the forwarding power control of at least one semi-static resource in the semi-static resource list; then, the forwarding node controls the forwarding power of the forwarding node on the at least one semi-static resource based on the activation indication information.

[0128] Exemplarily, each semi-static resource in the semi-static resource list is a periodic time-frequency resource.

[0129] For example, the semi-static resource list may include the following information: time-frequency resource 1 (offset and time period 1, cycle 1, frequency 1), time-frequency resource 2 (offset and time period 2, cycle 2, frequency 2), ..., time-frequency resource N (offset and time period N, cycle N, frequency N). Further, the semi-static forwarding power control configuration also includes a forwarding power adjustment amount corresponding to each time-frequency resource in the semi-static resource list, for example, it may include a forwarding power adjustment amount offset1 corresponding to time-frequency resource 1, a forwarding power adjustment amount offset2 corresponding to time-frequency resource 2, ..., a forwarding power adjustment amount offsetN corresponding to time-frequency resource N.

[0130] Of course, in other alternative embodiments, the frequency of each time-frequency resource in the semi-static resource list may be implicitly indicated, for example, if the forwarding node is configured with only one forwarding frequency, or the forwarding frequency of the forwarding node is the same as the frequency of the control link of the forwarding node, the semi-static resource list may not include information for indicating the frequency of each time-frequency resource. That is, the information included in the semi-static resource list can be simplified to: time-frequency resource 1 (offset and time period 1, cycle 1), time-frequency resource 2 (offset and time period 2, cycle 2), ..., time-frequency resource N (offset and time period N, cycle N).

[0131] Exemplarily, each semi-static resource in the semi-static resource list is a periodic spatiotemporal resource.

[0132] For example, the semi-static resource list may include the following information: space-time resource 1 (offset and time period 1, cycle 1, beam 1), space-time resource 2 (offset and time period 2, cycle 2, beam 2), ..., space-time resource N (offset and time period N, cycle N, beam N). Further, the semi-static forwarding power control configuration may also include a forwarding power adjustment amount corresponding to each space-time resource in the semi-static resource list, for example, it may include a forwarding power adjustment amount offset1 corresponding to space-time resource 1, a forwarding power adjustment amount offset2 corresponding to space-time resource 2, ..., a forwarding power adjustment amount offsetN corresponding to space-time resource N.

[0133] Exemplarily, each semi-static resource in the semi-static resource list is a periodic time-frequency-space resource.

[0134] For example, the semi-static resource list may include the following information: time-frequency-space resource 1 (offset and time period 1, cycle 1, frequency 1, beam 1), time-frequency-space resource 2 (offset and time period 2, cycle 2, frequency 2, beam 2), ..., time-frequency-space resource N (offset and time period N, cycle N, frequency N, beam N). Further, the semi-static forwarding power control configuration also includes the forwarding power adjustment amount corresponding to each time-frequency-space resource in the semi-static resource list, for example, it may include the forwarding power adjustment amount offset1 corresponding to time-frequency-space resource 1, the forwarding power adjustment amount offset2 corresponding to time-frequency-space resource 2, ..., the forwarding power adjustment amount offsetN corresponding to time-frequency-space resource N.

[0135] Of course, in other alternative embodiments, the frequency of each time-frequency space resource in the semi-static resource list may be implicitly indicated. For example, if the forwarding node is configured with only one forwarding frequency, or the forwarding frequency of the forwarding node is the same as the frequency of the control link of the forwarding node, the semi-static resource list may not include information for indicating the frequency of each time-frequency space resource. That is, the information included in the semi-static resource list can be simplified as: time-frequency space resource 1 (offset and time period 1, cycle 1, beam 1), time-frequency space resource 2 (offset and time period 2, cycle 2, beam 2), ..., time-frequency space resource N (offset and time period N, cycle N, beam N).

[0136] Exemplarily, the network side device may send the activation indication information to the forwarding node via MAC CE or Physical Downlink Control Channel (PDCCH). For example, the network side device may carry the activation indication information in MAC CE or PDCCH and send it to the forwarding node.

[0137] Exemplarily, the activation indication information may include at least one of the following: the at least one semi-static resource, and a forwarding power activation indication. After receiving the activation indication information, the forwarding node activates or reactivates the forwarding power control on the at least one semi-static resource in response to the activation indication information. For example, when the network side device needs to activate the forwarding power control on the semi-static resource 1, the activation indication information may include the sequence number of the semi-static resource 1 (for example, 1) and the forwarding power activation indication, and the forwarding power activation indication may be used to indicate the activation of the forwarding power control. For another example, when the network side device needs to activate the forwarding power control on all semi-static resources in a semi-static resource set, the activation indication information may include the sequence number of the semi-static resource set and the forwarding power activation indication, and the forwarding power activation indication may be used to indicate the activation of the forwarding power control.

[0138] Exemplarily, the activation indication information and the indication information for activating the beam can be carried using the same MAC CE or PDCCH. The same MAC CE or PDCCH may include at least one of the following: an identifier (e.g., a sequence number) of each of the at least one semi-static resource, a beam activation indication, and a forwarding power activation indication. Optionally, the identifier (e.g., a sequence number) of each of the at least one semi-static resource can be a mandatory parameter.

[0139] Exemplarily, the activation indication information can reuse the MAC CE carrying indication information for activating the beam, that is, for the at least one semi-static resource, when it is necessary to activate the beam configuration of the at least one semi-static resource and the forwarding power control on the at least one semi-static resource, the forwarding power control on the at least one semi-static resource can be activated while activating the beam configuration on the at least one semi-static resource. In this way, there is no need to introduce a new MAC CE, reduce the protocol complexity and save logical channel identifiers (logic channel identifier, LCID) or enhanced logical channel identifiers (enhanced logic channel identifier, eLCID).

[0140] Exemplarily, when the network side device configures a semi-static resource list to the forwarding node through RRC signaling, F1-AP signaling or OAM information, a semi-static resource set list can be configured, each semi-static resource set includes multiple semi-static resources and an identifier of the semi-static resource set (such as a serial number), and each semi-static resource includes a corresponding time period, frequency, beam configuration of the backhaul link (Backhaul Link), beam configuration of the access link (Access Link), and forwarding power adjustment amount. The network side device carries the identifier of the semi-static resource set in the MAC CE or PDCCH to activate the forwarding power control on the semi-static resources in the semi-static resource set. In this embodiment, the semi-static resource set formed by the at least one semi-static resource can be any semi-static resource set in the semi-static resource set list. That is, the network side device carries the identifier of the semi-static resource set formed by the at least one semi-static resource in the MAC CE or PDCCH to activate the forwarding power control on the semi-static resources in the semi-static resource set.

[0141] In some embodiments, the forwarding node controls the forwarding power of the forwarding node based on the semi-static forwarding power control configuration, which may be implemented as follows:

[0142] The forwarding node receives deactivation indication information sent by the network side device, and the deactivation indication information is used to indicate the deactivation or stop (also known as suspension) of the forwarding power control of at least one semi-static resource in the semi-static resource list; then, the forwarding node deactivates or stops the forwarding power control of the forwarding node on the at least one semi-static resource.

[0143] Exemplarily, the network side device may send the deactivation indication information to the forwarding node via MAC CE or PDCCH. In other words, the network side device may carry the deactivation indication information in MAC CE or PDCCH and send it to the forwarding node.

[0144] Exemplarily, the deactivation indication information may include at least one of the following: the at least one semi-static resource, and a forwarding power deactivation indication. After receiving the deactivation indication information, the forwarding node deactivates or suspends the forwarding power control on the at least one semi-static resource in response to the deactivation indication information. For example, if the network side device has activated the forwarding power control on the semi-static resource 1 and then needs to deactivate the forwarding power control on the semi-static resource 1, the deactivation indication information may include the sequence number of the semi-static resource 1 (for example, 1) and the forwarding power deactivation indication, and the forwarding power deactivation indication may be used to indicate the deactivation of the forwarding power control.

[0145] Exemplarily, the deactivation indication information and the indication information for deactivating the beam can be carried using the same MACCE or PDCCH. The same MAC CE or PDCCH may include at least one of the following: an identifier (e.g., a sequence number) of each of the at least one semi-static resource, a beam deactivation indication, and a forwarding power deactivation indication. Optionally, the identifier (e.g., a sequence number) of each of the at least one semi-static resource may be a mandatory parameter.

[0146] Exemplarily, the deactivation indication information can reuse the MACCE carrying indication information for deactivating the beam, that is, for the at least one semi-static resource, when it is necessary to deactivate the beam configuration of the at least one semi-static resource and the forwarding power control on the at least one semi-static resource, the forwarding power control on the at least one semi-static resource can be deactivated while deactivating the beam configuration on the at least one semi-static resource. In this way, there is no need to introduce a new MACCE, reduce the protocol complexity and save logical channel identifiers (Logic Channel Identifier, LCID) or enhanced logical channel identifiers (Enhanced Logic Channel Identifier, eLCID).

[0147] Exemplarily, when the network side device configures a semi-static resource list to the forwarding node through RRC signaling, F1-AP signaling or OAM information, a semi-static resource set list can be configured, each semi-static resource set includes multiple semi-static resources and an identifier of the semi-static resource set (such as a serial number), and each semi-static resource includes a corresponding time period, frequency, beam configuration of the backhaul link (Backhaul Link), beam configuration of the access link (Access Link), and forwarding power adjustment amount. The network side device carries the identifier of the semi-static resource set in the MAC CE or PDCCH to deactivate the forwarding power control on the semi-static resources in the semi-static resource set. In this embodiment, the semi-static resource set formed by the at least one semi-static resource can be any semi-static resource set in the semi-static resource set list. That is, the network side device carries the identifier of the semi-static resource set formed by the at least one semi-static resource in the MAC CE or PDCCH to deactivate the forwarding power control on the semi-static resources in the semi-static resource set.

[0148] In some embodiments, the forwarding node controls the forwarding power of the forwarding node on the at least one semi-static resource based on the activation indication information, which may be implemented as follows:

[0149] In response to the activation indication information carrying a first forwarding power adjustment amount corresponding to a target semi-static resource among the at least one semi-static resource, the forwarding node determines the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the first forwarding power adjustment amount; or, in response to the activation indication information not carrying the first forwarding power adjustment amount, the forwarding node determines the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the second forwarding power adjustment amount corresponding to the target semi-static resource in the semi-static forwarding power control configuration; the forwarding node determines the forwarding power of the forwarding node on the target semi-static resource based on the forwarding power amplification factor of the forwarding node on the target semi-static resource.

[0150] In other words, in response to the activation indication information carrying a first forwarding power adjustment amount corresponding to a target semi-static resource among the at least one semi-static resource, the forwarding node preferentially determines the forwarding power amplification factor of the forwarding node on the target semi-static resource based on (or using) the first forwarding power adjustment amount; otherwise, the forwarding node determines the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the second forwarding power adjustment amount corresponding to the target semi-static resource in the semi-static forwarding power control configuration.

[0151] Exemplarily, the forwarding node may determine the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the first forwarding power adjustment amount according to the following formula:

[0152] A(n)=Aref+offset(n)′(dB), j≥1.

[0153] Among them, A(n) represents the forwarding power amplification factor of the forwarding node on the target semi-static resource; n represents the identifier of the target semi-static resource (such as a serial number); Aref represents the reference forwarding power amplification factor, which can be pre-configured by the network side device or determined by the forwarding node itself; offset(n)′ represents the adjustment amount determined based on the first forwarding power adjustment amount.

[0154] Exemplarily, the forwarding node may determine the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the second forwarding power adjustment amount corresponding to the target semi-static resource in the semi-static forwarding power control configuration according to the following formula:

[0155] A(n)=Aref+offset(n)(dB), j≥1.

[0156] Among them, A(n) represents the forwarding power amplification factor of the forwarding node on the target semi-static resource; n represents the identifier of the target semi-static resource (such as a serial number); Aref represents the reference forwarding power amplification factor, which can be pre-configured by the network side device or determined by the forwarding node itself; offset(n) represents the adjustment amount determined based on the second forwarding power adjustment amount.

[0157] In this embodiment, since the first forwarding power adjustment amount is updated in real time, the forwarding power amplification factor of the forwarding node on the target semi-static resource is determined based on (or using) the first forwarding power adjustment amount, which can adapt to the real-time changes in the network status, thereby improving the accuracy of forwarding power control and the stability and performance of the forwarding node.

[0158] Figure 5 This is an example of a semi-static forwarding power control configuration provided according to an embodiment of the present application.

[0159] like Figure 5 As shown, the forwarding node receives the semi-static forwarding power control configuration sent by the network side device, and the semi-static forwarding power control configuration may include the semi-static resource list configured by the network side device for the forwarding node and the forwarding power adjustment amount corresponding to each semi-static resource in the semi-static resource list. For example, the semi-static resource list includes the target semi-static resource, and accordingly, the semi-static forwarding power control configuration includes the second forwarding power adjustment amount corresponding to the target semi-static resource. After receiving the semi-static forwarding power control configuration, the forwarding node may activate the forwarding power control of the forwarding node on at least one semi-static resource in the semi-static resource list by receiving activation indication information. Among them, the at least one semi-static resource includes the target semi-static resource, and the activation indication information carries the first forwarding power adjustment amount corresponding to the target semi-static resource. In this case, the forwarding node may control the forwarding power of the forwarding node on the target semi-static resource based on the first forwarding power adjustment amount, that is, preferentially use the first forwarding power adjustment amount carried in the activation indication information to control the forwarding power of the forwarding node on the target semi-static resource. Further, the forwarding node may also deactivate the forwarding power control of the forwarding node on the at least one semi-static resource by receiving deactivation indication information.

[0160] Figure 6 This is an example of a semi-static forwarding power control configuration provided according to an embodiment of the present application.

[0161] like Figure 6As shown, the forwarding node receives the semi-static forwarding power control configuration sent by the network side device, and the semi-static forwarding power control configuration may include the semi-static resource list configured by the network side device for the forwarding node and the forwarding power adjustment amount corresponding to each semi-static resource in the semi-static resource list. For example, the semi-static resource list includes the target semi-static resource, and accordingly, the semi-static forwarding power control configuration includes the second forwarding power adjustment amount corresponding to the target semi-static resource. After receiving the semi-static forwarding power control configuration, the forwarding node can activate the forwarding power control of the forwarding node on at least one semi-static resource in the semi-static resource list by receiving activation indication information. Among them, the at least one semi-static resource includes the target semi-static resource, and the activation indication information does not carry the first forwarding power adjustment amount corresponding to the target semi-static resource. In this case, the forwarding node determines the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the second forwarding power adjustment amount corresponding to the target semi-static resource in the semi-static forwarding power control configuration. Further, the forwarding node can also deactivate the forwarding power control of the forwarding node on the at least one semi-static resource by receiving deactivation indication information.

[0162] In some embodiments, the first forwarding power adjustment amount is the jth absolute adjustment amount (e.g., the absolute adjustment amount received for the jth time) received by the forwarding node for the target semi-static resource, where j is a positive integer; wherein the forwarding node determines the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the first forwarding power adjustment amount, which can be implemented as follows:

[0163] The forwarding node adds the first forwarding power adjustment amount to a reference forwarding power amplification factor to obtain the forwarding power amplification factor of the forwarding node on the target semi-static resource.

[0164] Exemplarily, the forwarding node may determine the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the first forwarding power adjustment amount according to the following formula:

[0165] A(j)=Aref+offset(j)(dB), j≥1.

[0166] Among them, A(j) represents the forwarding power amplification factor (i.e., the forwarding power amplification factor of the forwarding node on the target semi-static resource) determined based on the first forwarding power adjustment amount (i.e., the j-th absolute adjustment amount received by the forwarding node for the target semi-static resource); Aref represents the reference forwarding power amplification factor, which can be pre-configured by the network side device or determined by the forwarding node itself; offset(j) represents the first forwarding power adjustment amount (i.e., the j-th absolute adjustment amount received by the forwarding node for the target semi-static resource).

[0167] Exemplarily, the forwarding node may determine the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the first forwarding power adjustment amount according to the following formula:

[0168] A(n)=Aref+offset(n)′(dB), j≥1.

[0169] Among them, A(n) represents the forwarding power amplification factor of the forwarding node on the target semi-static resource; n represents the identifier of the target semi-static resource (for example, a serial number); Aref represents the reference forwarding power amplification factor, which can be pre-configured by a network-side device or determined by the forwarding node itself; offset(n)′ represents the adjustment amount determined based on the first forwarding power adjustment amount; in this embodiment, offset(n)′=offset(j), offset(j) represents the first forwarding power adjustment amount (that is, the jth absolute adjustment amount received by the forwarding node for the target semi-static resource).

[0170] In some embodiments, the first forwarding power adjustment amount is the jth relative adjustment amount received by the forwarding node for the target semi-static resource, where j is a positive integer; wherein the forwarding node determines the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the first forwarding power adjustment amount, which can be implemented as follows:

[0171] The forwarding node adds the first forwarding power adjustment amount, the first j-1 relative adjustment amounts received by the forwarding node for the target semi-static resource, and the reference forwarding power amplification factor to obtain the forwarding power amplification factor of the forwarding node on the target semi-static resource.

[0172] Exemplarily, the forwarding node may determine the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the first forwarding power adjustment amount according to the following formula:

[0173]

[0174] Wherein, A(j) represents the forwarding power amplification factor (i.e., the forwarding power amplification factor of the forwarding node on the target semi-static resource) determined based on the first forwarding power adjustment amount (i.e., the jth relative adjustment amount received by the forwarding node for the target semi-static resource); Aref represents the reference forwarding power amplification factor, which can be pre-configured by the network side device or determined by the forwarding node itself; Cmd k represents the kth relative adjustment amount (ie, the kth relative adjustment amount received by the forwarding node for the target semi-static resource), 1≤k≤j.

[0175] Exemplarily, the forwarding node may determine the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the first forwarding power adjustment amount according to the following formula:

[0176] A(n)=Aref+offset(n)′(dB), j≥1.

[0177] Wherein, A(n) represents the forwarding power amplification factor of the forwarding node on the target semi-static resource; n represents the identifier (such as the serial number) of the target semi-static resource; Aref represents the reference forwarding power amplification factor, which can be pre-configured by the network side device or determined by the forwarding node itself; offset(n)′ represents the adjustment amount determined based on the first forwarding power adjustment amount; in this embodiment, cmd k represents the kth relative adjustment amount (ie, the kth relative adjustment amount received by the forwarding node for the target semi-static resource), 1≤k≤j.

[0178] In some embodiments, the forwarding node determines the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the second forwarding power adjustment amount corresponding to the target semi-static resource in the semi-static forwarding power control configuration, which can be implemented as follows:

[0179] The forwarding node adds the second forwarding power adjustment amount to the reference forwarding power amplification factor to obtain the forwarding power amplification factor of the forwarding node on the target semi-static resource.

[0180] Exemplarily, the forwarding node may determine the forwarding power amplification factor of the forwarding node on the target semi-static resource based on the second forwarding power adjustment amount according to the following formula:

[0181] A(n)=Aref+offset(n)(dB), j≥1.

[0182] Wherein, A(n) represents the forwarding power amplification factor of the forwarding node on the target semi-static resource; n represents the identifier (e.g., serial number) of the target semi-static resource; Aref represents the reference forwarding power amplification factor, which can be pre-configured by a network-side device or determined by the forwarding node itself; offset(n) represents the adjustment amount determined based on the second forwarding power adjustment amount. In this embodiment, the forwarding node can directly determine the second forwarding power adjustment amount as the value of offset(n).

[0183] In some embodiments, the at least one forwarding power control configuration includes the periodic forwarding power control configuration, and the periodic forwarding power control configuration includes: a periodic resource list, and a forwarding power adjustment amount corresponding to each periodic resource in the periodic resource list; wherein S220 may include:

[0184] Based on the forwarding power adjustment amount corresponding to the target periodic resource in the periodic resource list in the periodic forwarding power control configuration, determine the forwarding power amplification factor of the forwarding node on the target periodic resource; based on the forwarding power amplification factor of the forwarding node on the target periodic resource, determine the forwarding power of the forwarding node on the target periodic resource.

[0185] Exemplarily, each periodic resource in the periodic resource list is a periodic time-frequency resource.

[0186] For example, the periodic resource list may include the following information: time-frequency resource 1 (offset and time period 1, period 1, frequency 1), time-frequency resource 2 (offset and time period 2, period 2, frequency 2), ..., time-frequency resource N (offset and time period N, period N, frequency N). Further, the periodic forwarding power control configuration also includes a forwarding power adjustment amount corresponding to each time-frequency resource in the periodic resource list, for example, it may include a forwarding power adjustment amount offset1 corresponding to time-frequency resource 1, a forwarding power adjustment amount offset2 corresponding to time-frequency resource 2, ..., a forwarding power adjustment amount offsetN corresponding to time-frequency resource N.

[0187] Of course, in other alternative embodiments, the frequency of each time-frequency resource in the periodic resource list may be implicitly indicated, for example, if the forwarding node is configured with only one forwarding frequency, or the forwarding frequency of the forwarding node is the same as the frequency of the control link of the forwarding node, the periodic resource list may not include information for indicating the frequency of each time-frequency resource. That is, the information included in the periodic resource list can be simplified as: time-frequency resource 1 (offset and time period 1, period 1), time-frequency resource 2 (offset and time period 2, period 2), ..., time-frequency resource N (offset and time period N, period N).

[0188] Exemplarily, each periodic resource in the periodic resource list is a periodic spatiotemporal resource.

[0189] For example, the periodic resource list may include the following information: space-time resource 1 (offset and time period 1, cycle 1, beam 1), space-time resource 2 (offset and time period 2, cycle 2, beam 2), ..., space-time resource N (offset and time period N, cycle N, beam N). Further, the periodic forwarding power control configuration may also include a forwarding power adjustment amount corresponding to each space-time resource in the periodic resource list, for example, it may include a forwarding power adjustment amount offset1 corresponding to space-time resource 1, a forwarding power adjustment amount offset2 corresponding to space-time resource 2, ..., a forwarding power adjustment amount offsetN corresponding to space-time resource N.

[0190] Exemplarily, each periodic resource in the periodic resource list is a periodic time-frequency-space resource.

[0191] For example, the periodic resource list may include the following information: time-frequency-space resource 1 (offset and time period 1, period 1, frequency 1, beam 1), time-frequency-space resource 2 (offset and time period 2, period 2, frequency 2, beam 2), ..., time-frequency-space resource N (offset and time period N, period N, frequency N, beam N). Further, the periodic forwarding power control configuration also includes the forwarding power adjustment amount corresponding to each time-frequency-space resource in the periodic resource list, for example, it may include the forwarding power adjustment amount offset1 corresponding to time-frequency-space resource 1, the forwarding power adjustment amount offset2 corresponding to time-frequency-space resource 2, ..., the forwarding power adjustment amount offsetN corresponding to time-frequency-space resource N.

[0192] Of course, in other alternative embodiments, the frequency of each time-frequency space resource in the periodic resource list may be implicitly indicated, for example, if the forwarding node is configured with only one forwarding frequency, or the forwarding frequency of the forwarding node is the same as the frequency of the control link of the forwarding node, the periodic resource list may not include information for indicating the frequency of each time-frequency space resource. That is, the information included in the periodic resource list can be simplified as: time-frequency space resource 1 (offset and time period 1, cycle 1, beam 1), time-frequency space resource 2 (offset and time period 2, cycle 2, beam 2), ..., time-frequency space resource N (offset and time period N, cycle N, beam N).

[0193] Exemplarily, the forwarding node may determine the forwarding power amplification factor of the forwarding node on the target periodic resource based on the forwarding power adjustment amount corresponding to the target periodic resource in the periodic forwarding power control configuration according to the following formula:

[0194] A(m)=Aref+offset(m)(dB), j≥1.

[0195] Among them, A(m) represents the forwarding power amplification factor of the forwarding node on the target periodic resource; m represents the identifier of the target periodic resource (such as a serial number); Aref represents the reference forwarding power amplification factor, which can be pre-configured by the network side device or determined by the forwarding node itself; offset(m) represents the adjustment amount determined based on the forwarding power adjustment amount corresponding to the target periodic resource.

[0196] In some embodiments, the forwarding node determines the forwarding power amplification factor of the forwarding node on the target periodic resource based on the forwarding power adjustment amount corresponding to the target periodic resource in the periodic resource list in the periodic forwarding power control configuration, which can be implemented as follows:

[0197] The forwarding node adds the forwarding power adjustment amount corresponding to the target periodic resource to the reference forwarding power amplification factor to obtain the forwarding power amplification factor of the forwarding node on the target periodic resource.

[0198] Exemplarily, the forwarding node may determine the forwarding power amplification factor of the forwarding node on the target periodic resource based on the forwarding power adjustment amount corresponding to the target periodic resource in the periodic forwarding power control configuration according to the following formula:

[0199] A(m)=Aref+offset(m)(dB), j≥1.

[0200] Wherein, A(m) represents the forwarding power amplification factor of the forwarding node on the target periodic resource; m represents the identifier (e.g., serial number) of the target periodic resource; Aref represents the reference forwarding power amplification factor, which can be pre-configured by the network side device or determined by the forwarding node itself; offset(m) represents the adjustment amount determined based on the forwarding power adjustment amount corresponding to the target periodic resource. In this embodiment, the forwarding node can directly determine the forwarding power adjustment amount corresponding to the target periodic resource as the value of offset(n).

[0201] Exemplarily, when the network side device configures the periodic resource list to the forwarding node through RRC signaling, F1-AP signaling or OAM information, a periodic resource set list can be configured, each periodic resource set includes multiple periodic resources and an identifier of the periodic resource set (such as a sequence number), and each periodic resource includes a corresponding time period, frequency, beam configuration of the backhaul link (Backhaul Link), beam configuration of the access link (Access Link), and forwarding power adjustment amount. When the forwarding node receives the periodic resource set list, it determines the corresponding forwarding power amplification factor based on the periodic resource and the corresponding forwarding power adjustment amount.

[0202] In some embodiments, the method 200 may further include:

[0203] The forwarding node receives release indication information sent by the network side device, where the release indication information is used to indicate the release of the at least one forwarding power control configuration; then, the forwarding node releases the at least one forwarding power control configuration or stops performing forwarding power control according to the at least one forwarding power control configuration.

[0204] Exemplarily, after receiving the release indication information sent by the network side device, the forwarding node releases the at least one forwarding power control configuration and stops performing forwarding power control according to the at least one forwarding power control configuration.

[0205] Exemplarily, the network side device may send the release indication information to the forwarding node via MAC CE or PDCCH. In other words, the network side device may carry the release indication information in MAC CE or PDCCH and send it to the forwarding node.

[0206] Figure 7 This is an example of a periodic forwarding power control configuration provided according to an embodiment of the present application.

[0207] like Figure 7 As shown, the forwarding node receives the periodic forwarding power control configuration sent by the network side device, and the periodic forwarding power control configuration may include a periodic resource list configured by the network side device for the forwarding node and a forwarding power adjustment amount corresponding to each periodic resource in the periodic resource list. For example, the periodic resource list includes a target periodic resource, and accordingly, the periodic forwarding power control configuration includes a forwarding power adjustment amount corresponding to the target periodic resource. The periodic forwarding power control configuration sent by the network side device takes effect immediately after the forwarding node receives it, that is, the forwarding node directly determines the forwarding power amplification factor of the forwarding node on the target periodic resource based on the forwarding power adjustment amount corresponding to the target periodic resource in the periodic forwarding power control configuration, and then determines the forwarding power of the forwarding node on the target periodic resource based on the forwarding power amplification factor of the forwarding node on the target periodic resource. Further, the forwarding node can also release the at least one forwarding power control configuration or stop performing forwarding power control according to the at least one forwarding power control configuration by receiving release indication information.

[0208] In some embodiments, the method 200 may further include:

[0209] In response to the at least one forwarding power control configuration not being released before the mobile terminal MT module of the forwarding node is released to an inactive state, when the MT module is released to an inactive state, the forwarding node continues to control the forwarding power of the forwarding node based on the at least one forwarding power control configuration.

[0210] In other words, before the mobile terminal MT module of the forwarding node is released to the inactive state, the at least one forwarding power control configuration is not released, and even in the case where the MT module is released to the inactive state, the forwarding node continues to control the forwarding power of the forwarding node based on the at least one forwarding power control configuration. Of course, in other alternative embodiments, in response to the at least one forwarding power control configuration not being released before the mobile terminal MT module of the forwarding node is released to the inactive state, the forwarding node may also release the at least one forwarding power control configuration or stop performing forwarding power control according to the at least one forwarding power control configuration when the MT module is released to the inactive state.

[0211] In some embodiments, the at least one forwarding power control configuration includes a plurality of forwarding power control configurations corresponding to the target resource; the method 200 may further include:

[0212] The forwarding node receives priority indication information sent by the network side device; the priority indication information is used to indicate the priority between the multiple forwarding power control configurations; based on the priority indication information, the forwarding node determines the forwarding power control configuration with the highest priority among the multiple forwarding power control configurations as the forwarding power control configuration used by the target resource; wherein the forwarding power control configuration used by the target resource is one of the following: a semi-static forwarding power control configuration with the highest priority among the multiple forwarding power control configurations, a periodic forwarding power control configuration with the highest priority among the multiple forwarding power control configurations, or a non-periodic forwarding power control configuration with the highest priority among the multiple forwarding power control configurations.

[0213] Exemplarily, the network side device may send the priority indication information to the forwarding node via MAC CE or PDCCH. In other words, the network side device may carry the priority indication information in MAC CE or PDCCH and send it to the forwarding node.

[0214] Exemplarily, the target resource includes overlapping resources of resource lists in the multiple forwarding power control configurations.

[0215] For example, when the resource list in the multiple forwarding power control configurations includes overlapping resources, the forwarding node receives the priority indication information sent by the network side device; the forwarding node determines the forwarding power control configuration with the highest priority among the multiple forwarding power control configurations as the forwarding power control configuration used for the overlapping resources based on the priority indication information. In other words, when the resource list in the multiple forwarding power control configurations includes overlapping resources, the network side device sends the priority indication information to the forwarding node, so that the forwarding node determines the forwarding power control configuration with the highest priority among the multiple forwarding power control configurations as the forwarding power control configuration used for the overlapping resources based on the priority indication information.

[0216] Exemplarily, the target resource may be a target resource block, such as a time-frequency resource block, a time-space resource block, or a time-frequency-space resource block.

[0217] Exemplarily, the non-periodic forwarding power control configuration may also be referred to as a dynamic forwarding power control configuration, which is a configuration that is sent on demand (i.e., dynamically) by a network-side device through a MAC CE or PDCCH, and controls (e.g., adjusts) the forwarding power of a resource block (e.g., a time-frequency resource, a time-space resource, or a time-frequency-space resource). After receiving the non-periodic forwarding power control configuration, the forwarding node controls the forwarding power of the forwarding node on the corresponding resource block. For example, after receiving the non-periodic forwarding power control configuration, the forwarding node may determine the forwarding power amplification factor of the forwarding node on the target resource block based on the forwarding power adjustment amount corresponding to the target resource block in the non-periodic forwarding power control configuration, and then determine the forwarding power of the forwarding node on the target resource block based on the forwarding power amplification factor of the forwarding node on the target resource block.

[0218] In some embodiments, the plurality of forwarding power control configurations include one of the following:

[0219] Multiple semi-static forwarding power control configurations;

[0220] Multiple periodic forwarding power control configurations;

[0221] at least one semi-static forwarding power control configuration and at least one periodic forwarding power control configuration;

[0222] at least one semi-static forwarding power control configuration and at least one aperiodic forwarding power control configuration;

[0223] at least one periodic forwarding power control configuration and at least one aperiodic forwarding power control configuration;

[0224] At least one semi-static forwarding power control configuration, at least one periodic forwarding power control configuration, and at least one aperiodic forwarding power control configuration.

[0225] In other words, the priority indication information is used to indicate one of the following: the priority between multiple semi-static forwarding power control configurations; the priority between multiple periodic forwarding power control configurations; the priority between at least one semi-static forwarding power control configuration and at least one periodic forwarding power control configuration; the priority between at least one semi-static forwarding power control configuration and at least one non-periodic forwarding power control configuration; the priority between at least one periodic forwarding power control configuration and at least one non-periodic forwarding power control configuration; the priority between at least one semi-static forwarding power control configuration, at least one periodic forwarding power control configuration, and at least one non-periodic forwarding power control configuration.

[0226] For example, when the multiple forwarding power control configurations include at least one semi-static forwarding power control configuration and at least one periodic forwarding power control configuration, the priority indication information may include the priority between the at least one semi-static forwarding power control configuration and the at least one periodic forwarding power control configuration.

[0227] Exemplarily, the semi-static resources (e.g., semi-static resources configured by the semi-static forwarding power control configuration) corresponding to different semi-static forwarding power control configurations among the at least one semi-static forwarding power control configuration or the multiple semi-static forwarding power control configurations have different periods. Alternatively, the terminals (e.g., terminals to which the semi-static forwarding power control configuration is applicable) corresponding to different semi-static forwarding power control configurations among the at least one semi-static forwarding power control configuration or the multiple semi-static forwarding power control configurations are different. Alternatively, the channels (e.g., channels to which the semi-static forwarding power control configuration is applicable) corresponding to different semi-static forwarding power control configurations among the at least one semi-static forwarding power control configuration or the multiple semi-static forwarding power control configurations are different.

[0228] Exemplarily, the periodic resources (e.g., periodic resources configured by the periodic forwarding power control configuration) corresponding to different periodic forwarding power control configurations in the at least one periodic forwarding power control configuration or the multiple periodic forwarding power control configurations are different. Alternatively, the terminals (e.g., terminals to which the periodic forwarding power control configuration is applicable) corresponding to different periodic forwarding power control configurations in the at least one periodic forwarding power control configuration or the multiple periodic forwarding power control configurations are different. Alternatively, the channels (e.g., channels to which the periodic forwarding power control configuration is applicable) corresponding to different periodic forwarding power control configurations in the at least one periodic forwarding power control configuration or the multiple periodic forwarding power control configurations are different.

[0229] Figure 8 It is a schematic flowchart of a forwarding power control method 300 provided according to an embodiment of the present application.

[0230] The forwarding power control method 300 may be interactively executed by a forwarding node and a network side device. The forwarding node may be any node that can amplify a signal and forward information (e.g., a forwarding node in a 5G or 6G system), or the forwarding node may be a node that can perform power control and is used to forward signals between a UE and a network side device. For example, the forwarding node may be an NCR node. The network side device may be any access network device. For example, Figure 8 The forwarding node shown in can be Figure 1 The forwarding node 130 shown, Figure 8 The network devices shown in can be Figure 1 The network side device 120 is shown.

[0231] like Figure 8 As shown, the forwarding power control method 300 may include at least part of the following contents:

[0232] S310, a forwarding node receives priority indication information sent by a network side device; the priority indication information is used to indicate the priority between multiple forwarding power control configurations.

[0233] Exemplarily, the network side device may send the priority indication information to the forwarding node via MAC CE or PDCCH. In other words, the network side device may carry the priority indication information in MAC CE or PDCCH and send it to the forwarding node.

[0234] S320, based on the priority indication information, the forwarding node determines the forwarding power control configuration with the highest priority among the multiple forwarding power control configurations as the forwarding power control configuration used by the target resource corresponding to the multiple forwarding power control configurations; wherein the forwarding power control configuration used by the target resource is one of the following: a semi-static forwarding power control configuration with the highest priority among the multiple forwarding power control configurations, a periodic forwarding power control configuration with the highest priority among the multiple forwarding power control configurations, or a non-periodic forwarding power control configuration with the highest priority among the multiple forwarding power control configurations.

[0235] In some embodiments, the plurality of forwarding power control configurations include one of the following:

[0236] Multiple semi-static forwarding power control configurations;

[0237] Multiple periodic forwarding power control configurations;

[0241] At least one semi-static forwarding power control configuration, at least one periodic forwarding power control configuration, and at least one aperiodic forwarding power control configuration.

[0242] It should be understood that the steps and terms (such as target resources or forwarding power control configuration) in the forwarding power control method 300 can refer to the description of the corresponding steps and related terms in the forwarding power control method 200, and will not be repeated here to avoid repetition.
