Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a terminal uplink power control method and device in a converged sensing network. Background Technology

[0002] Communication sensing fusion technology is an innovative application based on existing mobile communication infrastructure to realize environmental target sensing functions. Base stations or terminals can carry out sensing services in the form of single-station sensing (self-transmitting and self-receiving sensing signals) or dual-station sensing (separate devices sending and receiving sensing signals).

[0003] With the introduction of sensing functionality into network base station equipment, signal interference between base stations becomes more complex. If a sensing signal transmitted by a sensing base station coincides with a communication signal from a neighboring base station on the same frequency, the sensing signal will interfere with the uplink reception of the neighboring station or the downlink reception of the terminal. Currently, to avoid interference between sensing signals and communication signals, resource orthogonality is mainly used. This solution primarily manages the interference level between sensing signals and communication signals through power control, enabling the coexistence of uplink signals and neighboring station sensing signals. For example, the uplink signal reception of the serving base station and the sensing signal reception of the neighboring station may occupy several identical time slots.

[0004] When the terminal's uplink signal and the sensing signal from a neighboring base station coexist in the same frequency, existing technologies have the following problems: The original uplink power control mechanism of the terminal is only suitable for pure communication scenarios and does not consider the interference of sensing signals from adjacent base stations, lacking targeted interference constraint factors. For example, when the terminal's uplink power is too high, it will superimpose with the sensing signals of adjacent base stations to form strong interference, affecting the target sensing accuracy of adjacent base stations. When the power is too low, it will lead to insufficient reliability of its own communication link and reduced data transmission rate.

[0005] The lack of a coordinated power control mechanism between the terminal and the network side, as well as between adjacent base stations, means that the terminal cannot obtain sensing signal parameters (such as sensing power, beam direction, and occupied resources) in real time. This results in power adjustment lagging behind interference changes, making it difficult to achieve dynamic controllability of interference.

[0006] To address this, this solution proposes a terminal-side uplink power control method. By controlling the transmission power, interference between sensing signals and uplink communication signals can coexist, thereby improving spectrum utilization while ensuring the performance of both services.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] Figure 1 This is a schematic diagram illustrating the coexistence of signal interference between a sensing base station and a neighboring station in the background technology. (Example:) Figure 1 As shown, in time slots 1 and 6, the uplink signal reception of the serving base station and the sensing signal reception of the neighboring station occupy the same time slot, forming a state of coexistence of communication and sensing interference.

[0032] Current power control schemes for terminals mainly include two methods: open-loop and closed-loop power control.

[0033] Open-loop power control: The terminal estimates the uplink path loss (PL) based on downlink measurements (such as the path loss reference signal PL-RS), and autonomously calculates the initial transmit power by combining the target received power parameter (P0) configured by the network and the path loss compensation factor (α). The compensation ratio is flexibly adjusted by α (with a value of 0~1) to avoid excessive power increase that could lead to interference.

[0034] Closed-loop power control: Based on received signal quality (such as SINR, BLER) measurements, the network side sends dynamic power control commands (TPC commands) to the terminal via the downlink control channel (DCI) to fine-tune the transmit power in real time. This supports multiple closed-loop circuits (such as independent configurations for eMBB / URLLC services) to adapt to different service reliability requirements. The core logic is a combination of "open-loop foundation + scenario-based compensation + closed-loop fine-tuning," ultimately limited by the terminal's hardware capabilities.

[0035] The formula for combining open-loop and closed-loop power control is shown below:

[0036] In the formula, the subscript "x" represents the specific uplink channel (e.g., x=PUSCH / PUCCH / SRS / PRACH), corresponding to the differentiated parameter configuration of each channel. : The final uplink transmit power of the corresponding channel (unit: dBm); : Maximum transmit power supported by terminal hardware (fixed physical constraint, unit: dBm); The target received power baseline value for the corresponding channel (configured by the network via RRC signaling, unit: dBm) provides a reference for open-loop power calculation; : The path loss compensation factor for the corresponding channel (value 0~1, network configuration), used to balance coverage and interference; The uplink path loss estimate (in dB) for the corresponding channel is derived by the terminal from the downlink reference signal. The number of physical resource blocks (RBs) corresponding to the channel is determined by... Converted to power offset to compensate for differences in resource usage; : The dedicated power offset (unit: dB) for each channel, adapting to the different characteristics of each channel such as format, bandwidth, and preamble; : The cumulative adjustment amount of the closed-loop power control (TPC) for the corresponding channel (unit: dB). It only applies to channels that support closed-loop adjustment and allows for real-time fine-tuning of power as needed.

[0037] Currently, to avoid interference between sensing signals and communication signals, resource orthogonality is mainly used. However, this solution mainly uses power control to manage the interference level between sensing signals and communication signals, so as to support the coexistence of uplink signals and neighboring station sensing signals.

[0038] This solution proposes a terminal uplink power control method to support the coexistence of interference between the terminal's transmitted uplink signal and the received signal from neighboring stations. The method includes the following technical features: the serving base station provides uplink power control configuration parameters for coexistence with interference from neighboring station received signals, or introduces an uplink power control factor constrained by the interference from the sensed signal. The core idea is to introduce a set of power configuration parameters for coexistence with interference from the sensed signal of neighboring base stations into the uplink power configuration information, or to introduce an additional sensed signal interference constraint factor. This controls the interference from the terminal's uplink signal to the sensed signal of neighboring base stations within a preset range, while simultaneously supporting effective uplink transmission, thus achieving coexistence of interference from both sensing and communication services.

[0039] Figure 2 This is a flowchart illustrating an embodiment of the method described in this application. This application proposes a terminal uplink power control method, comprising the following steps 110-130: Step 110: Determine whether the uplink signal transmission is in a state of coexistence with the sensing signal of the neighboring station.

[0040] The coexistence of sensing interference refers to a situation where the uplink signal of the terminal and the sensing signal of the adjacent base station use the same or overlapping time-frequency resources, resulting in potential or actual mutual interference between the signals. This is a prerequisite for implementing targeted power control, which can be determined by the network-side equipment and notified to the terminal, or the terminal can determine it itself based on the received resource indication information.

[0041] Step 120: If the state of coexistence of inductive and syn-interference is in the state of coexistence, then generate or obtain the uplink power control parameters or inductive and syn-interference constraint factors for the state.

[0042] These parameters or factors are specifically designed to manage inductive interference. For example, the network side can generate a set of power control configuration parameters that differ from those used in traditional communication scenarios, or introduce an independent interference constraint factor Δ. The parameters can be dynamically calculated by the network side based on the interference situation, or they can be pre-configured and sent to the terminal by the base station.

[0043] Step 130: Determine the transmit power of the terminal's uplink signal based on the uplink power control parameters or the inductive interference constraint factor.

[0044] The terminal adjusts its uplink transmit power calculation based on new parameters or factors. For example, when using dedicated configuration parameters, the terminal's maximum transmit power, target receive power, path loss compensation factor, etc., may be adjusted to values ​​more suitable for interference coexistence. When using the interference constraint factor Δ, this factor can be superimposed on the result of the traditional power calculation formula. When Δ is negative, the power is reduced to decrease interference to neighboring station sensing; when Δ is positive, the power is increased to counteract interference from sensing signals to the uplink signal.

[0045] It should be noted that the above steps are used for network entities in a wireless communication system, including terminal-side devices, network-side devices, or other intermediate devices; the above steps can also be used for service devices that provide information processing for the network entity devices; the above steps can also be used for any device, system, subsystem, circuit, chip, or software entity that provides information reception, transmission, identification, and processing for terminal-side devices or network-side devices.

[0046] Figure 3 This is a schematic diagram illustrating the application of uplink power control configuration parameters and sensing signal interference constraint factors in this application. For example... Figure 3 As shown, the serving base station and its neighboring base stations experience coexistence of uplink signal and sensing signal interference in time slots 1 and 6. In time slots 1 and 6, the serving base station uses uplink power control configuration parameters for coexistence of neighboring station sensing and receiving signal interference to control uplink signal power, and the terminal calculates the uplink signal power based on the relevant parameters. In time slots 4-5 and 9-10, the serving base station uses traditional uplink power control configuration parameters to control uplink signal power, and the terminal calculates the uplink signal power using traditional power control configuration parameters.

[0047] The uplink power control configuration parameters provided by the serving base station for coexistence with interference from neighboring station received signals may include the terminal's maximum transmit power. Target received power Path loss compensation factor of the channel At least one of them.

[0048] The subscript "x" represents the specific uplink channel (e.g., PUSCH / PUCCH / SRS / PRACH), corresponding to the differentiated parameter configurations for each channel, represent different uplink channels that can correspond to different target receive powers. Path loss compensation factor of the channel Configuration. Optional, different uplink channels can also correspond to the same target received power. Path loss compensation factor of the channel Configuration, i.e. , , It is not related to the channel type, but to whether it coexists with interference from neighboring station's sensed received signals.

[0049] Therefore, the general formula for uplink signal power control in this scheme, which addresses interference with neighboring station sensing and receiving signals, can be: (1) Taking the uplink data channel PUSCH as an example, the power control formula for the traditional PUSCH is set as follows: (2) in The path loss is measured based on the reference resource corresponding to q. , , They represent the interval between the carrier and the subcarrier, respectively. Physical RB quantity The MCS level and the power parameters related to the i-th closed-loop power control adjustment. In traditional power control, the target power parameters... With road loss compensation factor Related to the business type and deployment environment, for example Different configurations are required for eMBB and URLLC services. Different configuration parameters are applied to deployments in densely populated urban areas and suburbs. Based on this design, the maximum transmit power, target receive power, channel path loss compensation factor, and whether the uplink PUSCH coexists with interference from neighboring station sensed receive signals are considered. When interference coexists between the PUSCH and neighboring station sensed receive signals, the uplink data channel power control calculation formula is as follows: (3) If there is no interference during coexistence, then the traditional power control configuration parameters are used.

[0050] The sensing signal interference constrains the uplink power control factor This represents the power control factor when the serving base station provides uplink signal power to the terminal that coexists with interference from neighboring station received signals; the terminal adds this factor when calculating uplink power. Therefore, under this method, the terminal uplink power control calculation formula can be expressed as: (4) In the formula, the subscript "x" represents the specific uplink channel (e.g., The differentiated parameter configurations for each channel indicate that different uplink channels can correspond to different perceived signal interference constraint uplink power control factors. Optionally, different uplink channels can also correspond to the same perceived signal interference constraint uplink power control factor configuration.

[0051] Optionally, the serving base station can configure the range of relevant parameters for uplink signal transmission that coexists with interference from neighboring station sensing signals. For example, it can set the range of the number of resource blocks occupied by the corresponding uplink signal, the PUCCH format type, the bandwidth range occupied by the uplink signal, the PRACH signal preamble format type, etc., thereby adjusting the transmission power of the uplink signal.

[0052] Figure 4 This is a flowchart illustrating an embodiment of the method of this application used in a network-side device. The method described in any embodiment of the first aspect of this application, used in a network-side device, includes the following steps 210-240: Step 210: The network-side equipment determines the power control parameters or factors that need to be configured for the terminal in the case of coexistence of inductive and synoptic interference.

[0053] Step 220: The network-side device sends uplink power control configuration parameters or inductive interference constraint factors to the terminal for the coexistence of inductive and inductive interference.

[0054] This is the core action performed on the network side. The uplink power control configuration parameters for the coexistence of inductive and sensorial interference can include the terminal's maximum transmit power. Target received power Path loss compensation factor of the channel At least one of them.

[0055] The subscript "x" represents the specific uplink channel (e.g., x = PUSCH / PUCCH / SRS / PRACH), corresponding to the differentiated parameter configurations for each channel. Optionally, different uplink channels can also correspond to the same target received power. Path loss compensation factor of the channel Configuration, i.e. , , It is not related to the channel type, but to whether it coexists with interference from neighboring station's sensed received signals.

[0056] Step 230: Optionally, the network-side device sends indication information to the terminal, the indication information being used to indicate the uplink time slot or time-frequency resource in the state of coexistence of the inductive interference.

[0057] For example, the serving base station sends neighboring station sensing frame structure information to the terminal, informing the terminal which uplink resources (specifically indicating which uplink time slots or uplink time-frequency resources) coexist with the sensing signal reception interference of neighboring base stations.

[0058] Step 240: Optionally, the network-side device sends an activation signaling or a deactivation signaling to the terminal to control whether the terminal adopts the power control mechanism for the coexistence of inductive and sensorial interference.

[0059] The serving base station sends a signaling instruction to the terminal indicating whether to activate or deactivate uplink power control based on uplink power control configuration parameters for coexistence of neighboring station perceived signal reception interference, or on uplink power control factors constrained by perceived signal interference. If the terminal receives the activation signaling instruction, it calculates the uplink signal transmission power for uplink signals with coexistence of neighboring station perceived signal reception interference, based on the relevant configuration parameters provided by the base station or the uplink power control factor constrained by perceived signal interference, at the effective time of the signaling instruction. If the terminal receives the deactivation signaling instruction, it calculates the uplink signal power based on the traditional power control configuration, at the effective time of the signaling instruction.

[0060] Furthermore, the network-side device can obtain neighboring base station sensing frame structure information, and / or frame structure update information, and / or sensing interference indication information from the core network or neighboring base stations. Based on this information, the serving base station configures uplink power control parameters to accommodate interference from neighboring station sensing signals, or introduces sensing signal interference constraints on the uplink power control factor. The sensing interference indication information may include the information described in Table 1, including: sensing interference power spectral density (ISD), sensing interference level indication (Interference Level), sensing interference source indication, and interference percentage in edge regions.

[0061] Table 1. Inductive Interference Indication Information

[0062] Network-side devices can send the uplink power control configuration parameters or inductive interference constraint factors to a group of end users or a single end user.

[0063] Network-side devices can also send activation or deactivation signals to a group of end users or a single end user.

[0064] Optionally, the serving base station sends uplink power control configuration parameters, or sensing signal interference constraint uplink power control factor, to a group of terminal users or a single terminal user.

[0065] Optionally, the serving base station instructs a group of terminal users or a single terminal user to send uplink power control activation and deactivation signaling to the terminal, based on uplink power control configuration parameters for coexistence of neighboring station perceived signal reception interference or uplink power control factor constrained by perceived signal interference. The terminal receiving the signaling then calculates the uplink signal transmission power (activation signaling) based on the relevant configuration parameters or uplink power control factor constrained by perceived signal interference provided by the base station, or calculates the uplink signal power (deactivation signaling) based on the traditional power control configuration, at the effective time of the signaling.

[0066] Figure 5 This is a flowchart illustrating an embodiment of the method of this application used in a terminal-side device. The method described in any embodiment of the first aspect of this application, used in a terminal-side device, includes the following steps 310-340: Step 310: The terminal-side device receives information from the network-side device. The information may include one or more of the following: uplink power control configuration parameters or inductive interference constraint factors for the coexistence state of inductive interference, indication information indicating inductive interference coexistence resources, activation or deactivation signaling, etc.

[0067] Step 320: Based on the received information, the terminal device determines whether the current uplink transmission is in a state of coexistence of induction and communication interference, and whether a power control mechanism for this state should be enabled.

[0068] Step 330: If enabled, determine the uplink signal transmission power in the coexistence state of inductive interference based on the received uplink power control configuration parameters or inductive interference constraint factor for the coexistence state of inductive interference.

[0069] For example, when using dedicated configuration parameters, the general formula for terminal uplink power control can be Equation (1); when using an interference constraint factor, the calculation formula for terminal uplink power control can be expressed as Equation (4). Perceived signal interference constraint uplink power control factor It can be negative to reduce power and reduce interference to neighboring stations, or it can be positive to increase uplink power and reduce interference from neighboring station sensing signals to the uplink signal.

[0070] Step 340: The terminal transmits an uplink signal at the determined transmit power.

[0071] Therefore, the specific implementation steps of uplink power control in this scheme for coexistence with neighboring station sensing signal reception interference include: 1) The serving base station sends uplink power control configuration parameters for coexistence with neighboring station sensing signal reception interference to the terminal, or introduces a sensing signal interference constraint uplink power control factor. 2) The terminal calculates the uplink signal transmission power based on the uplink power control configuration parameters for coexistence with neighboring station sensing signal reception interference or the sensing signal interference constraint uplink power control factor provided by the serving base station.
