Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a power control method, a terminal device, and a network device. Background Technology

[0002] In New Radio (NR) systems, two services have been introduced: Ultra-Reliable and Low-Latency Communication (URLLC) and Enhanced Mobile Broadband (eMBB). URLLC is characterized by achieving ultra-high reliability (e.g., 99.999%) transmission within extremely short latency (e.g., 1ms), while eMBB is insensitive to latency but can handle a large number of transmissions. In scenarios where URLLC and eMBB coexist, conflicts may occur between them to ensure real-time URLLC transmission. Interference from eMBB transmission can affect URLLC transmission, with the conflict between uplink URLLC and uplink eMBB being particularly pronounced. Therefore, ensuring uplink URLLC transmission even when conflicts occur is a critical technical challenge that needs to be addressed. Summary of the Invention

[0003] This application provides a power control method, a terminal device, and a network device, in which power adjustment information is associated with resources, making power control for URLLC more targeted and efficient.

[0004] In a first aspect, a power control method is provided, the method comprising:

[0005] The terminal device receives first information, which includes at least one power adjustment information;

[0006] The terminal device determines the transmission power based on the at least one power adjustment information and power configuration information, wherein the power configuration information includes at least a first correspondence, and the first correspondence is the correspondence between the power adjustment information and the resources.

[0007] It should be understood that this power control method is used to control the transmission power of URLLC. That is, in the event of a conflict between URLLC and eMBB, the interference caused by eMBB transmission is overcome by controlling the transmission power of URLLC.

[0008] It should be noted that since the power boost made to overcome eMBB interference depends on the resource location of eMBB and URLLC, interpreting the power adjustment information based on this first correspondence makes the power control of URLLC more targeted and efficient.

[0009] Secondly, a power control method is provided, the method comprising:

[0010] The network device sends first information, wherein the first information includes at least one power adjustment information, the power adjustment information has a first correspondence with resources, and the first information is used by the terminal device to determine the transmission power.

[0011] Thirdly, a terminal device is provided for executing the methods described in the first aspect or its various implementations.

[0012] Specifically, the terminal device includes a functional module for performing the methods described in the first aspect or its various implementations.

[0013] Fourthly, a network device is provided for performing the methods described in the second aspect or its various implementations.

[0014] Specifically, the network device includes a functional module for performing the methods described in the second aspect or its various implementations.

[0015] Fifthly, a terminal device is provided, including a processor and a memory. The memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to perform the methods described in the first aspect or its various implementations.

[0016] In a sixth aspect, a network device is provided, including a processor and a memory. The memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to perform the methods in the second aspect or its implementations described above.

[0017] In a seventh aspect, an apparatus is provided for implementing the method in any one of the first to second aspects or in any of their implementations.

[0018] Specifically, the device includes a processor for calling and running a computer program from memory, causing a device equipped with the device to perform the method as described in any of the first to second aspects above or in their respective implementations.

[0019] Eighthly, a computer-readable storage medium is provided for storing a computer program that causes a computer to perform the methods of any one of the first to second aspects or their respective implementations.

[0020] Ninthly, a computer program product is provided, including computer program instructions that cause a computer to perform the methods of any one of the first to second aspects or their respective implementations.

[0021] In a tenth aspect, a computer program is provided that, when run on a computer, causes the computer to perform the methods of any one of the first to second aspects or their respective implementations.

[0022] With the above technical solution, since the power boost made to overcome eMBB interference depends on the resource location of eMBB and URLLC, interpreting the power adjustment information based on the first correspondence makes the power control of URLLC more targeted and more efficient.

[0033] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art without creative effort regarding the embodiments of this application are within the scope of protection of this application.

[0034] The embodiments of this application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, evolution system of NR system, LTE-based access to unlicensed spectrum (LTE-U) system, NR-based access to unlicensed spectrum (NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication systems, or other communication systems, etc.

[0035] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC) communication, and vehicle-to-vehicle (V2V) communication. The embodiments of this application can also be applied to these communication systems.

[0036] Optionally, the communication system in this application embodiment can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) network deployment scenario.

[0037] The embodiments of this application do not limit the spectrum to which the application is applied. For example, the embodiments of this application can be applied to licensed spectrum or unlicensed spectrum.

[0038] For example, the communication system 100 used in the embodiments of this application is as follows: Figure 1 As shown. The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal, terminal). The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area.

[0039] Figure 1 An exemplary embodiment shows a network device and two terminal devices. Optionally, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.

[0040] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in this embodiment.

[0041] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above, which will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as network controllers, mobility management entities and other network entities. This application embodiment does not limit this.

[0042] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0043] This application describes various embodiments in conjunction with terminal devices and network devices, wherein: the terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device, etc. The terminal device may be a station (STAION, ST) in a WLAN, a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, and next-generation communication system, such as terminal device in an NR network or terminal device in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0044] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0045] Network devices can be devices used to communicate with mobile devices. Network devices can be access points (APs) in WLANs, base stations (BTSs) in GSM or CDMA, base stations (NodeBs, NBs) in WCDMA, evolved base stations (eNBs or eNodeBs) in LTE, relay stations or access points, or in-vehicle devices, wearable devices, and network devices or base stations (gNBs) in NR networks, or network devices in future evolved PLMN networks, etc.

[0046] In this embodiment, the network device provides services to the cell, and the terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be the cell corresponding to the network device (e.g., base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0047] like Figure 2 As shown, UE1 sends uplink data A for eMBB to gNB on the time domain resources of time slot k and the frequency domain resources of physical resource blocks (PRBs) j to PRB i, and UE2 sends uplink data B for URLLC to gNB on the time domain resources of time slot k and the frequency domain resources of PRBs j to PRB i. Then, uplink eMBB and uplink URLLC will collide at gNB.

[0048] Regarding the conflict between uplink URLLC and uplink eMBB transmissions, such as Figure 2 As shown, there are two main solutions: 1) Stop eMBB transmission to reduce interference with URLLC. 2) Increase the URLLC transmit power to ensure that the URLLC receive SINR meets demodulation requirements even if eMBB interference exists. The former completely eliminates interference but requires increasing the complexity of the eMBB terminal. The latter maintains the receive signal-to-interference-plus-noise ratio (SINR) by increasing the useful signal power, and only requires enhancement of the URLLC.

[0049] It should be understood that uplink power control is very important in wireless communication systems. Through uplink power control, the UE in the cell can ensure the quality of the data transmitted uplink while minimizing interference to other users in the system and extending the battery life of the UE.

[0050] Currently, the uplink power control implemented in NR versions (Release 15, Rel 15) mainly includes the power control and configuration of the following channels:

[0051] -Physical Uplink Shared Channel (PUSCH) power control

[0052] -Physical Uplink Control Channel (PUCCH) power control

[0053] –Sounding Reference Signal (SRS) channel power control

[0054] –Physical Random Access Channel (PRACH) power control

[0055] – Configure UE to report power margin, supporting periodic and event-triggered reporting.

[0056] In addition, in order to support inter-cell interference coordination, load and interference information need to be transmitted on the X2 interface.

[0057] The current transmission power of PUSCH can be calculated using the following formula 1:

[0058]

[0059] Where i is the index of a single PUSCH transmission, and j is the index of open-loop power control parameters (including the target power P). O_PUSCH,b,f,c (j) and road loss factor α b,f,c (j));q d It is an index of the reference signal used for road loss measurement, used to obtain the road loss value PL. b,f,c (q d f is also an open-loop power control parameter. b,f,c (i,l) is the closed-loop power control adjustment factor, where l is the closed-loop power control process.

[0060] Specifically, the terminal device determines the closed-loop power adjustment factor based on the Transmit Power Control (TPC) command field sent by the network device. This TPC command field can be carried in the Downlink Control Information (DCI) used to schedule the PUSCH in the terminal device's search space, or it can be carried in the DCI format 2_2 used to carry the group TPC command field in the common search space.

[0061] It should be understood that NR Rel15 uses Group common DCI (e.g., DCI format 2_2) and UE-specific DCI (e.g., DCI format 0_0 / 0_1) to indicate closed-loop adjustment power.

[0062] The characteristics of Group Common DCI are: 1) One DCI contains power indication information for multiple users; 2) Multiple field values ​​in the DCI are for multiple users. Information such as the user's domain index and the target base station is configured through higher-layer signaling.

[0063] The UE-specific DCI method is characterized by indicating power adjustment information for the user within a user-specific scheduling signaling. UE-specific DCI includes DCI format 0_0 and DCI format 0_1.

[0064] Uplink power control includes open-loop power control and closed-loop power control.

[0065] 1) Set a target receive power and roughly determine the uplink transmit power based on path loss, scheduling resources, modulation and coding scheme, etc., i.e. open-loop power control.

[0066] 2) Faster adaptation can send power adjustment information to the terminal in a timely manner, control interference and adjust power settings to adapt to channel conditions, i.e., closed-loop power control.

[0067] It should be noted that the closed-loop power control (TPC information) is indicated through DCI format 2_2 or UE-specific DCI (DCI format 1_0 / 1_1).

[0068] For DCI format 2_2, URLLC users affected by eMBB interference are not always in a single DCI format 2_2. Therefore, the base station needs to send multiple DCI format 2_2 messages, which increases signaling overhead.

[0069] For UE-specific DCI, each affected URLLC user must independently send indication information. In particular, for semi-persistent or semi-static (configured grant) transmission modes, users do not need to receive UE-specific DCI when transmitting data. However, to improve power, additional power indications need to be received / sent, thus increasing signaling overhead.

[0070] To address the aforementioned technical issues, this application proposes a power control scheme where power adjustment information is resource-specific. Since the power boost achieved to overcome eMBB interference depends on the resource locations of eMBB and URLLC, the power parameter values ​​are resource-specific, making power control more targeted and efficient.

[0071] The following details the power control scheme designed in this application to address the aforementioned technical problems.

[0072] Figure 3 This is a schematic flowchart of a power control method 200 according to an embodiment of this application, such as... Figure 3 As shown, the method 200 may include the following:

[0073] S210, the network device sends first information to the terminal device, wherein the first information includes at least one power adjustment information, the power adjustment information has a first correspondence with the resource, and the first information is used by the terminal device to determine the transmission power;

[0074] S220, the terminal device receives the first information;

[0075] S230, the terminal device determines the transmission power based on the at least one power adjustment information and power configuration information, wherein the power configuration information includes at least the first correspondence.

[0076] It should be understood that the embodiments of this application can be applied to scenarios where uplink URLLC and uplink eMBB transmissions conflict. They are mainly used to control the transmission power of uplink URLLC, thereby overcoming the interference caused by uplink eMBB transmission to the transmission of uplink URLLC. For example, controlling the transmission power of uplink URLLC in PUSCH and / or PUCCH.

[0077] It should also be understood that, in the embodiments of this application, the transmission power can also be referred to as the transmit power.

[0078] Optionally, the first information can be DCI, or it can be a broadcast or system broadcast. That is, the signaling carrying the power adjustment information can be DCI, or it can be a broadcast or system broadcast.

[0079] Optionally, the first information may be specific to the terminal device, meaning it is terminal device-specific signaling. For example, if the first information is DCI (Digital Communication Interface), it may be specific to the terminal device. Similarly, if the first information is a broadcast or system broadcast, it may also be specific to the terminal device. The first information may also be specific to a group of terminal devices that includes at least the terminal device, meaning it is terminal device group-specific signaling. For example, if the first information is a broadcast or system broadcast, it may be specific to a group of terminal devices that includes at least the terminal device.

[0080] It should be noted that when the first information is only for the terminal device, the configuration is simple and the higher-layer signaling overhead is small. When the first information is for a group of terminal devices that includes at least the terminal device, the terminal devices in the group can share the at least one power adjustment information carried by the first information, thereby reducing the physical layer signaling overhead.

[0081] Optionally, in step S210 above, the network device may send the first information based on the power configuration information.

[0082] Optionally, in this embodiment, after receiving the first information, the terminal device can interpret the at least one power adjustment information carried by the first information based on the power configuration information, thereby determining the transmission power on the corresponding resource. That is, in step S230 above, the terminal device can determine the transmission power on the corresponding resource based on the at least one power adjustment information and the power configuration information.

[0083] Optionally, before receiving the first information, the terminal device may determine the power configuration information. For example, if the power configuration information is configured by the network device through higher-layer signaling (e.g., Radio Resource Control (RRC) signaling, Media Access Control Control Element (MAC CE) signaling, etc.), the terminal device receives the signaling carrying the power configuration information. Alternatively, if the power configuration information is pre-configured or protocol-defined, the terminal device may invoke or read the power configuration information.

[0084] Optionally, in the embodiments of this application, the first correspondence is pre-configured or configured by the network device.

[0085] For example, the network device configures the first mapping relationship through higher-layer signaling (e.g., RRC signaling, MAC CE signaling, etc.).

[0086] For example, the protocol pre-defines various mapping relationships between power adjustment information and resources. The network device can instruct the terminal device via higher-layer signaling which mapping relationship to use, that is, to indicate the first mapping relationship among the various power adjustment information and resource mapping relationships for the terminal device. This increases the flexibility of system configuration.

[0087] For example, the network device pre-configures various mapping relationships between power adjustment information and resources for the terminal device, and the network device can instruct the terminal device via higher-layer signaling which mapping relationship to use, i.e., instructing the terminal device to use the first mapping relationship among the various power adjustment information and resource mapping relationships. This increases the flexibility of system configuration.

[0088] Optionally, the network device may send first configuration information to the terminal device. This first configuration information includes at least one power configuration information, which in turn includes at least the first correspondence. That is, the network device can configure a correspondence between at least one power adjustment information and resources using the first configuration information.

[0089] Optionally, the resources in the first correspondence include at least one of the following:

[0090] Time-domain resources, frequency-domain resources, and time-frequency-domain resources.

[0091] Optionally, the resources in the first correspondence are determined by preset rules and / or network device configuration.

[0092] Specifically, if the resources in the first correspondence are determined by a preset rule, then the first correspondence satisfies at least one of the following relationships:

[0093] Each of the K indication fields in a set of power adjustment information corresponds to the full bandwidth resource or a portion of the bandwidth of at least one symbol in a time slot;

[0094] Each of the L indication fields in a set of power adjustment information corresponds to the full bandwidth resource or a portion of the bandwidth of at least one symbol in N time slots.

[0095] Optionally, as Example 1, the first correspondence satisfies that: a set of power adjustment information corresponds to the full bandwidth resources of one time slot (14 symbols). For example, a set of power adjustment information can correspond to the full bandwidth resources of one time slot (14 symbols), and the set of power adjustment indication information contains 14 fields, each field representing the full bandwidth resources of one symbol in the full bandwidth resources of the one time slot (14 symbols). Assuming each field uses 2 bits to indicate the power adjustment information corresponding to one symbol, then the 14 fields require a total of 28 bits, with each 2 bits sequentially indicating the power adjustment information on the full bandwidth resources of one symbol, such as... Figure 4 As shown.

[0096] Optionally, as Example 2, the first correspondence satisfies that N power adjustment information pieces correspond to the full bandwidth resources of N time slots. For example, a set of power adjustment information may include N power adjustment information pieces, each power adjustment information piece corresponding to the full bandwidth resources of one time slot out of the N time slots. For example, as... Figure 4 As shown, this set of power adjustment information contains 14 fields, each corresponding to the full bandwidth resources of one symbol in one time slot.

[0097] Optionally, as Example 3, this first correspondence satisfies that each domain in a set of power adjustment information corresponds to the full bandwidth resources of multiple symbols in a time slot (14 symbols) or 1 / 2 times the full bandwidth resources. For example... Figure 5 As shown, a set of power adjustment indication information contains 14 fields, each field corresponding to half of the full bandwidth resource of every two symbols in the full bandwidth resource of a time slot (14 symbols). When each field uses 2 bits to indicate the power adjustment information, the 14 fields require 28 bits, with each pair of bits sequentially indicating the power adjustment information of half of the full bandwidth resource of two symbols in a time slot.

[0098] It should be noted that since URLLC scheduling is usually high bandwidth, frequency domain resources can be mapped to power adjustment information in units of full bandwidth or half bandwidth.

[0099] Specifically, if the resources in the first correspondence are determined through network device configuration, then the first correspondence is the correspondence between power adjustment information bits and pre-configured resources.

[0100] Optionally, if the resources in the first correspondence are determined through network device configuration, the network device needs to configure semi-persistent / semi-static (configured grant) resources. For example, the terminal device receives second information sent by the network device, which is used to configure at least one pre-configured resource. This pre-configured resource is the configured grant resource.

[0101] It should be noted that URLLC uplink transmissions often utilize pre-configured resources to reduce latency, meaning data is sent on predefined resources without the need for physical layer signaling. For example, there is no need for DCI scheduling, nor for scheduling requests (SRs) or buffer status reports (BSRs). For time-frequency domain resource indications of URLLC transmissions over configured grants, these can be based on the configured grant configuration. The technical advantages are: reduced signaling overhead (configured grant configurations are limited; for example, a user can configure a maximum of 8 configured grant resources), and more precise resource mapping (compared to half the bandwidth or full bandwidth, the granularity of this method is PRB).

[0102] Optionally, in this embodiment of the application, the power configuration information may further include a first spatial domain corresponding to the power adjustment information.

[0103] In other words, the embodiments of this application take into account the different levels of interference between different spatial domains, and the power control based on spatial domain indication is more accurate, avoiding unnecessary power boosts (for example, there is no need to boost the power of two users whose spaces are orthogonal).

[0104] In other words, the resources in the first correspondence may include at least one of time-domain resources, frequency-domain resources, and time-frequency-domain resources, as well as beam-domain resources and / or precoding codebook resources.

[0105] It should be noted that the spatial domain can include the beam domain, or it can include different precoding codebook domains on the same beam.

[0106] Optionally, the power configuration information specifically includes a first scrambling method used in the signaling carrying the power adjustment information. This first scrambling method indicates the first spatial domain corresponding to the power adjustment information. That is, after receiving the first information, the terminal device can interpret the first spatial domain corresponding to the scrambling method based on the first scrambling method. In this case, the at least one power adjustment information carried by the first information corresponds to the first spatial domain. Furthermore, the network device needs to send the first information based on the first scrambling method.

[0107] For example, the scrambling method of the first information is A, and the first information includes power adjustment information 1 and power adjustment information 2. The terminal device can interpret the scrambling method as A based on the first scrambling method and determine the first spatial domain S, that is, both power adjustment information 1 and power adjustment information 2 correspond to the first spatial domain S.

[0108] Optionally, the first scrambling method can be pre-configured, protocol-defined, or configured for the network device. For example, the network device configures the first scrambling method through higher-layer signaling.

[0109] It should be noted that this first information can be scrambled using a Radio Network Temporary Identity (RNTI), for example, by configuring a corresponding RNTI for each spatial direction.

[0110] Optionally, the power configuration information specifically includes the bit position of the power adjustment information in the signaling carrying the power adjustment information, and the bit position is used to indicate the first spatial domain corresponding to the power adjustment information. That is, after receiving the first information, the terminal device can interpret the first spatial domain corresponding to the at least one power adjustment information based on the bit position. Furthermore, the network device needs to send the first information based on the bit position.

[0111] For example, the first information includes power adjustment information 1 and power adjustment information 2. Power adjustment information 1 is located in bit 1 of the first information, and power adjustment information 2 is located in bit 2 of the first information. The terminal device can interpret bit 1 based on the bit position and determine the first spatial domain k, and interpret bit 2 based on the bit position and determine the first spatial domain t. That is, power adjustment information 1 corresponds to the first spatial domain k, and power adjustment information 2 corresponds to the first spatial domain t.

[0112] Optionally, the bit position can be pre-configured, protocol-defined, or configured for the network device. For example, the network device configures the bit position via higher-layer signaling.

[0113] Optionally, in this embodiment of the application, the power configuration information may further include a first bandwidth part (BWP) corresponding to the power adjustment information.

[0114] It should be noted that since different users have different BWPs, that is, different frequency domain bandwidths in the resources, it is necessary to determine a unified bandwidth definition. Otherwise, it will be difficult for network devices to indicate a unified time-frequency domain resource through a single signaling.

[0115] Optionally, the first BWP is a reference bandwidth, which may be pre-configured or configured for the network device. For example, the reference bandwidth may be the system bandwidth.

[0116] Optionally, the power configuration information specifically includes a second scrambling method used in the signaling carrying the power adjustment information. This second scrambling method indicates the first BWP corresponding to the power adjustment information. That is, after receiving the first information, the terminal device can interpret the first BWP corresponding to the scrambling method of the first information based on the second scrambling method. In this case, the at least one power adjustment information carried by the first information corresponds to the first BWP. Furthermore, the network device needs to send the first information based on the second scrambling method.

[0117] For example, the scrambling method of the first information is B, and the first information includes power adjustment information 1 and power adjustment information 2. The terminal device can interpret the scrambling method as B based on the second scrambling method and determine the first spatial domain P, that is, both power adjustment information 1 and power adjustment information 2 correspond to the first spatial domain P.

[0118] Optionally, the second scrambling method can be pre-configured, protocol-defined, or configured for the network device. For example, the network device configures the second scrambling method through higher-layer signaling.

[0119] It should be noted that this initial information can be scrambled using RNTI, for example, by configuring a corresponding RNTI for each BWP.

[0120] For example, the DCI of RNTI 1 scrambled Cyclical Redundancy Check (CRC) indicates 1-100 PRB of the system's maximum bandwidth, while the DCI of RNTI 2 scrambled CRC indicates 101-200 PRB of the maximum bandwidth.

[0121] Optionally, the terminal device is configured with at least one Power Control Panel (BWP), and each of the at least one BWP is configured with power configuration information. That is, for a terminal device, power configuration information is configured independently under each BWP, and power adjustment information under that BWP is read based on the power configuration information.

[0122] It should be noted that for different terminal devices, the power parameters under the same BWP configuration are at least the same RNTI, which allows different terminal devices operating on the same BWP to share a DCI.

[0123] Optionally, the network device sends second configuration information to the terminal device, the second configuration information being used to configure at least one BWP, and each of the at least one power configuration information is for one of the at least one BWPs.

[0124] Optionally, in this embodiment of the application, the power configuration information further includes at least one timing information, which is used to indicate the effective time of the at least one power adjustment information.

[0125] It should be noted that the at least one timing information allows the terminal device sufficient time to parse the first information and the at least one power adjustment information carried by the first information, and after determining the transmission power on the corresponding resource, the power can be adjusted.

[0126] Optionally, the timing information includes, but is not limited to, at least one of the following:

[0127] Capability information for a specific time period and a particular terminal device, and the next uplink transmission.

[0128] It should be noted that the terminal device's capability information can reflect the minimum processing time from downlink transmission to feedback and from uplink scheduling to uplink transmission. In other words, this timing information can be a type of terminal device capability information.

[0129] Optionally, the timing information is pre-configured or configured for the network device.

[0130] Optionally, in this embodiment of the application, the power configuration information further includes at least one of the following:

[0131] The RNTI used for CRC scrambling of the DCI carrying the power adjustment information, wherein the first information is the DCI;

[0132] The size of the signaling message carrying the power adjustment information;

[0133] In a multi-carrier scenario, the power adjustment information of at least one carrier in the multi-carrier system is represented by its bit or index information.

[0134] It should be noted that if the signaling carrying the power adjustment information is transmitted through the PDCCH, and the power configuration information includes: the RNTI used for CRC scrambling of the DCI carrying the power adjustment information, and / or the size of the signaling carrying the power adjustment information, it can help the terminal device to blindly detect the PDCCH, thereby obtaining the signaling carrying the power adjustment information more quickly.

[0135] When the power configuration information includes, in a multi-carrier scenario, the bit or index information of the power adjustment information of at least one carrier in the multi-carrier scenario, the support for multi-carrier scenarios can be extended.

[0136] It should be noted that, in the embodiments of this application, the power boost made to overcome eMBB interference is the same for all interfered users, that is, to supplement the eMBB interference energy and ensure that the received SINR of the interfered user on the receiving side does not become too worse. Therefore, it is not necessary to use a user-specific power indicator.

[0137] Therefore, in this embodiment, since the power adjustment information is resource-specific, power control becomes more targeted and efficient. Furthermore, the power adjustment information is sent either user-group-specific or broadcast, meaning that sharing information among multiple users does not affect performance and reduces signaling overhead.
