[0071] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0072] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0073] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0074] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0075] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0076] like Figure 1 As shown, a terminal output power control method according to an embodiment of the present invention is applied to a communication device, including:

[0077] Step 101, determining the home cell of the target terminal;

[0078] Step 102: Determine the maximum power level of the terminal acceptable to the home cell according to a first preset correspondence between the cell and the maximum power level of the terminal allowed by the application scenario.

[0079] In this embodiment, a correspondence between a cell and a terminal maximum power level allowed by an application scenario is preset, that is, a first preset correspondence. Thus, through the first preset correspondence, the cell corresponding to the application scenario can obtain the terminal maximum power level allowed in an application scenario, and use it as the acceptable terminal maximum power level of the cell corresponding to the application scenario.

[0080] Therefore, according to the above steps, the communication device first determines the target terminal's belonging cell, and then according to the first preset corresponding relationship, it can further determine the terminal's maximum power level acceptable to the belonging cell. Since the terminal's maximum power level acceptable to the belonging cell is the terminal's maximum power level allowed by the application scenario corresponding to the belonging cell, it is possible to determine the terminal output power level based on the application scenario, thereby reducing unnecessary losses in the uplink coverage capability of the terminal, especially industry terminals.

[0081] Optionally, in the first preset corresponding relationship, the maximum power level of the terminal allowed by the application scenario includes at least one of the following:

[0082] Preset fixed power levels;

[0083] Corresponding to power levels in different dimensions.

[0084] Here, the preset fixed power level is set according to the maximum power level of the terminal allowed by the application scenario under normal circumstances. The power levels corresponding to different dimensions are set according to the maximum power level of the terminal allowed by the application scenario in each dimension. For example, if the dimension is the time dimension, the maximum power level of the terminal allowed by the application scenario in the first time period is Class A, and the maximum power level of the terminal allowed in another second time period is Class B; or, if the dimension is the temperature dimension, the maximum power level of the terminal allowed by the application scenario in the first temperature range is Class C, and the maximum power level of the terminal allowed in another second temperature range is Class D. Of course, the implementation of this dimension includes but is not limited to the time dimension and the temperature dimension, and it can also be a combination of multiple dimensions, which are not listed here one by one.

[0085] Optionally, in the first preset corresponding relationship, the cell is represented by an identity identification number ID of the cell, or the cell is represented by a physical cell identifier PCI of the cell.

[0086] Thus, for the first preset correspondence, if the cell is represented by a cell ID, the first preset correspondence is the correspondence between the cell ID and the maximum power level of the terminal allowed by the application scenario; if the cell is represented by a cell PCI, the first preset correspondence is the correspondence between the cell PCI and the maximum power level of the terminal allowed by the application scenario. Of course, in the first preset correspondence, the cell ID and the cell PCI can also be recorded at the same time.

[0087] In this embodiment, PCI represents a cell-specific reference information. When the cell is initially synchronized, the primary synchronization sequence PSS and the secondary synchronization sequence SSS can be retrieved through the cell search process, and the PCI is calculated by combining the two. In real networking, it is inevitable to reuse PCI, which may cause the same PCI to conflict due to a small reuse distance (PCI conflict). Through reasonable PCI planning (physical cell ID planning), PCI can be reasonably allocated to each cell to ensure that the downlink signals of cells with the same frequency and PCI will not interfere with each other, avoiding affecting the correct synchronization of the terminal and decoding of the pilot channel of the normal service cell.

[0088] In the long-term evolution LTE system, 504 different PCIs (value range 0 to 503) are defined, and each PCI corresponds to a specific downlink reference signal sequence; the set of all PCIs is divided into 168 groups (value range 0 to 167), each group contains 3 cell ID indication information (value range 0 to 2). During network management configuration, a number between 0 and 503 is configured for the LTE cell, namely the cell ID. During the LTE cell search process, the PSS (there are 3 possibilities) and SSS (there are 168 possibilities) are retrieved and combined to determine the specific cell ID.

[0089] In the new radio interface NR system, 1008 different PCIs (value range 0-1007) are defined, and each PCI corresponds to a specific downlink reference signal sequence; the set of all PCIs is divided into 336 groups (value range 0-335), each group contains 3 cell ID indication information (value range 0-2). During network management configuration, a number between 0 and 1007, namely the cell ID, is configured for the NR cell. During the NR cell search process, the PSS (there are 3 possibilities) and SSS (there are 336 possibilities) are retrieved and combined to determine the specific cell ID.

[0090] In this way, for the 5G NR system, 1008 different PCIs are segmented, and different segments correspond to different application scenarios. Terminals accessing different application scenarios have specific maximum allowable output power requirements, that is, the highest power level of the terminal allowed by the application scenario. Then, the first preset correspondence relationship can be shown in the following table:

[0091]

[0092] Table 1

[0093] Of course, expressing the first preset corresponding relationship through a table is only a preferred implementation method, and the first preset corresponding relationship can also be implemented through other methods, which will not be described here.

[0094] In this embodiment, the communication device to which the method of the embodiment of the present invention is applied may be a terminal.

[0095] Therefore, in this embodiment, optionally, the communication device is the target terminal, and step 101 includes:

[0096] In the case where the first preset correspondence uses a cell ID to represent a cell, obtaining a PCI of the home cell, and determining an ID of the home cell according to a second preset correspondence between the PCI and the cell ID;

[0097] In the case where the first preset correspondence uses the cell PCI to represent the cell, the PCI of the home cell is obtained.

[0098] In this way, in the case where the cell ID is used to represent the cell in the first preset correspondence, it is necessary to first obtain the PCI of the cell to which the target terminal belongs, and then determine the ID of the cell to which the target terminal belongs according to the second preset correspondence between the PCI and the cell ID. Subsequently, in the first preset correspondence, the ID of the cell to which the target terminal belongs can be queried to obtain the highest power level of the terminal acceptable to the cell to which the target terminal belongs in the corresponding application scenario from the ID of the cell to which the target terminal belongs. In the case where the cell PCI is used to represent the cell in the first preset correspondence, after obtaining the PCI of the cell to which the target terminal belongs, in the first preset correspondence, the PCI of the cell to which the target terminal belongs can be queried to obtain the highest power level of the terminal acceptable to the cell to which the target terminal belongs in the corresponding application scenario from the PCI of the cell to which the target terminal belongs.

[0099] Among them, the second preset correspondence between the cell PCI and the cell ID is predefined or preconfigured. For example, as shown in Table 1, the number of PCI groups and cell groups (i.e., ID groups) is the same, and they correspond in sequence. Of course, the correspondence between PCI groups and cell groups can also be other, for example, cell groups with IDs: 0 to 99 correspond to PCI groups with PCIs: 100 to 199; and cell groups with IDs: 100 to 199 correspond to PCI groups with PCIs: 300 to 399, rather than corresponding in sequence.

[0100] In addition, for the target terminal, when determining the highest power level of the terminal acceptable to the home cell, it can not only actively report, but also report based on the needs of the network side device. Therefore, optionally, after determining the highest power level of the terminal acceptable to the home cell, it also includes:

[0101] Receive inquiry signaling sent by network side equipment;

[0102] According to the transmission capability of the target terminal and the determined maximum power level of the terminal acceptable to the home cell, a first target power level is fed back to the network side device.

[0103] That is, after receiving the inquiry signaling sent by the network side device, the target terminal reports the power level. Figure 2 As shown, the network side device such as the base station gNB1 sends the terminal power level inquiry signaling RRC_UE_PWR_ENQUIRY of the cell to the target terminal UE1, and the target terminal provides feedback through the feedback signaling RRC_UE_PWR_INFO.

[0104] Here, the target terminal can directly inform the network side device of the terminal maximum power level acceptable to the belonging cell determined by the method of the embodiment of the present invention. However, considering the transmission capability of the target terminal itself, the target terminal will combine its transmission capability and the determined terminal maximum power level acceptable to the belonging cell to feedback the first target power level to ensure the subsequent terminal operation is realized. Here, when the determined terminal maximum power level acceptable to the belonging cell exceeds the terminal transmission capability, that is, the determined terminal maximum power level acceptable to the belonging cell is greater than the maximum power level supported by the terminal capability, the first target power level is the maximum power level supported by the terminal capability; when the determined terminal maximum power level acceptable to the belonging cell does not exceed the terminal transmission capability, that is, the determined terminal maximum power level acceptable to the belonging cell is less than or equal to the maximum power level supported by the terminal capability, the first target power level is the determined terminal maximum power level acceptable to the belonging cell.

[0105] In addition, in this embodiment, the communication device to which the method of the embodiment of the present invention is applied may be a network side device.

[0106] For the network side device, the network side device is aware of the ID of the corresponding cell, therefore, in the first preset correspondence used by the network side device, the cell is preferably represented by the cell ID to reduce storage space and processing flow.

[0107] The network-side device can determine the home cell ID from the relevant information of the target terminal accessing the network, and then directly query in the first preset corresponding relationship to determine the highest power level of the terminal acceptable to the home cell.

[0108] However, considering the transmission capability of the target terminal, the determined maximum power level of the terminal acceptable to the home cell is not compatible. Optionally, after determining the maximum power level of the terminal acceptable to the home cell, the network side device further includes:

[0109] A broadcast message is sent, wherein the broadcast message carries the determined maximum power level of the terminal acceptable to the home cell.

[0110] Optionally, the broadcast message includes a master system information block MIB and / or a system information block SIB.

[0111] The MIB and / or SIB indicates the maximum power level of the terminal acceptable to the cell by adding bit information.

[0112] Since the network side device can obtain the maximum terminal power level acceptable to the target terminal's home cell through the first preset corresponding relationship, the network side device can directly broadcast to enable multiple terminals to obtain the maximum terminal power level acceptable to their home cells. Of course, the target terminal can also obtain the maximum terminal power level acceptable to its home cell through the broadcast message.

[0113] In combination with its own transmission capability, the target terminal can actively report, and can also report based on the needs of the network side device. Optionally, after sending the broadcast message, the network side device also includes:

[0114] Send inquiry signaling;

[0115] A second target power level fed back by the target terminal according to the inquiry signaling is received; the second target power level is determined by the target terminal according to its own transmission capability and the highest terminal power level acceptable to the home cell carried by the broadcast message.

[0116] Here, when the determined maximum power level of the terminal acceptable to the belonging cell exceeds the terminal transmission capability, that is, the determined maximum power level of the terminal acceptable to the belonging cell is greater than the maximum power level supported by the terminal capability, the second target power level is the maximum power level supported by the terminal capability; when the determined maximum power level of the terminal acceptable to the belonging cell does not exceed the terminal transmission capability, that is, the determined maximum power level of the terminal acceptable to the belonging cell is less than or equal to the maximum power level supported by the terminal capability, the second target power level is the determined maximum power level of the terminal acceptable to the belonging cell.

[0117] For example, Figure 3 As shown, the network side device such as gNB2 sends MIB, which carries the determined maximum terminal power level acceptable to the UE2's home cell. After UE2 receives RRC_UE_PWR_ENQUIRY sent by gNB2, it feeds back through RRC_UE_PWR_INFO. Here, the fedback power level is obtained by combining UE2's own transmission capability and the known maximum terminal power level acceptable to the home cell.

[0118] Or, if Figure 4As shown, the network side device such as gNB3 sends a SIB, which carries the determined maximum terminal power level acceptable to the cell to which UE3 belongs. UE3 can further learn the maximum terminal power level acceptable to its cell through the SIB. After UE3 receives the RRC_UE_PWR_ENQUIRY sent by gNB3, it provides feedback through RRC_UE_PWR_INFO. Here, the feedback power level is obtained by combining UE3's own transmission capability and the known maximum terminal power level acceptable to the cell to which it belongs.

[0119] Of course, in order to facilitate the terminal to obtain the cell power level information as early as possible, it can be considered to carry the cell power level information in the SIB1 or SIB2 message.

[0120] In summary, the method of the embodiment of the present invention first determines the home cell of the target terminal, and then, based on the first preset correspondence, it is possible to further determine the maximum power level of the terminal acceptable to the home cell, wherein the first preset correspondence is a correspondence between the pre-set cell and the maximum power level of the terminal allowed by the application scenario. In this way, since the maximum power level of the terminal acceptable to the home cell is the maximum power level of the terminal allowed by the application scenario corresponding to the home cell, it is possible to determine the terminal output power level based on the application scenario, thereby reducing the unnecessary loss of uplink coverage capability of the terminal, especially the industry terminal.

[0121] like Figure 5 As shown, a terminal output power control device according to an embodiment of the present invention includes:

[0122] A first processing module 510 is used to determine a home cell of a target terminal;

[0123] The second processing module 520 is configured to determine the terminal maximum power level acceptable to the home cell according to a first preset correspondence between the cell and the terminal maximum power level allowed by the application scenario.

[0124] Optionally, in the first preset corresponding relationship, the cell is represented by an identity identification number ID of the cell, or the cell is represented by a physical cell identifier PCI of the cell.

[0125] Optionally, in the first preset corresponding relationship, the maximum power level of the terminal allowed by the application scenario includes at least one of the following:

[0126] Preset fixed power levels;

[0128] In this embodiment, the apparatus may be implemented as a communication device.

[0129] Optionally, the communication device is the target terminal, and the first processing module includes:

[0130] A first processing submodule, configured to obtain the PCI of the home cell when the first preset correspondence uses the cell ID to represent the cell, and determine the ID of the home cell according to a second preset correspondence between the PCI and the cell ID;

[0131] The second processing submodule is configured to obtain the PCI of the home cell when the first preset correspondence uses the cell PCI to represent the cell.

[0132] Optionally, the communication device is the target terminal, and the apparatus further includes:

[0133] A first receiving module, used to receive an inquiry signaling sent by a network side device;

[0134] The first sending module is used to feed back a first target power level to the network side device according to the transmission capability of the target terminal and the determined maximum power level of the terminal acceptable to the home cell.

[0135] Optionally, the communication device is a network side device, and the apparatus further includes:

[0136] The second sending module is used to send a broadcast message, wherein the broadcast message carries the determined maximum power level of the terminal acceptable to the home cell.

[0137] Optionally, the device further comprises:

[0138] A third sending module, used for sending an inquiry signaling;

[0139] The second receiving module is used to receive the second target power level fed back by the target terminal according to the inquiry signaling; the second target power level is determined by the target terminal according to its own transmission capability and the highest terminal power level acceptable to the belonging cell carried by the broadcast message.

[0140] Optionally, the broadcast message includes a master system information block MIB and / or a system information block SIB.

[0141] The device first determines the home cell of the target terminal, and then can further determine the maximum power level of the terminal acceptable to the home cell according to the first preset correspondence, wherein the first preset correspondence is the correspondence between the preset cell and the maximum power level of the terminal allowed by the application scenario. In this way, since the maximum power level of the terminal acceptable to the home cell is the maximum power level of the terminal allowed by the application scenario corresponding to the home cell, it is possible to determine the terminal output power level based on the application scenario, thereby reducing the unnecessary loss of uplink coverage capability of the terminal, especially the industry terminal.

[0155] According to the transmission capability of the target terminal and the determined maximum power level of the terminal acceptable to the home cell, a first target power level is fed back to the network side device.

[0156] Optionally, the communication device is a network side device, and the network side device includes a second transceiver, and the second transceiver is used to:

[0157] A broadcast message is sent, wherein the broadcast message carries the determined maximum power level of the terminal acceptable to the home cell.

[0158] Optionally, the second transceiver is further used for:

[0159] Send inquiry signaling;

[0160] A second target power level fed back by the target terminal according to the inquiry signaling is received; the second target power level is determined by the target terminal according to its own transmission capability and the highest terminal power level acceptable to the home cell carried by the broadcast message.

[0161] Optionally, the broadcast message includes a master system information block MIB and / or a system information block SIB.

[0162] The communication device of this embodiment first determines the home cell of the target terminal, and then further determines the maximum power level of the terminal acceptable to the home cell according to the first preset correspondence, wherein the first preset correspondence is the correspondence between the preset cell and the maximum power level of the terminal allowed by the application scenario. In this way, since the maximum power level of the terminal acceptable to the home cell is the maximum power level of the terminal allowed by the application scenario corresponding to the home cell, it is possible to determine the terminal output power level based on the application scenario, thereby reducing the unnecessary loss of uplink coverage capability of the terminal, especially the industry terminal.

[0163] A computer-readable storage medium according to an embodiment of the present invention stores a computer program, and when the computer program is executed by a processor, the steps in the terminal output power control method described above are implemented, and the same technical effect can be achieved. To avoid repetition, it is not repeated here. The computer-readable storage medium is, for example, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk.

[0164] It should be further explained that the terminal described in this specification is preferably an industry terminal with a relatively fixed application scenario, and many of the functional components described are referred to as modules in order to more particularly emphasize the independence of their implementation methods.

[0165] In the embodiment of the present invention, module can be implemented with software so that it can be executed by various types of processors. For example, an executable code module of an identification can include one or more physical or logical blocks of computer instructions, for example, it can be constructed as an object, process or function. Nevertheless, the executable code of the identified module does not need to be physically located together, but can include different instructions stored in different positions, and when these instructions are logically combined together, it constitutes a module and realizes the specified purpose of the module.

[0166] In fact, executable code module can be a single instruction or many instructions, and can even be distributed on a plurality of different code segments, distributed among different programs, and distributed across a plurality of memory devices. Similarly, operating data can be identified in the module, and can be implemented and organized in the data structure of any appropriate type according to any appropriate form. The operating data can be collected as a single data set, or can be distributed in different locations (including on different storage devices), and can only be present on a system or network as an electronic signal at least in part.

[0167] When a module can be implemented by software, considering the level of existing hardware technology, a person skilled in the art can build a corresponding hardware circuit to implement the corresponding function of the module that can be implemented by software without considering the cost. The hardware circuit includes a conventional very large scale integration (VLSI) circuit or gate array and existing semiconductors such as logic chips, transistors, or other discrete components. The module can also be implemented by a programmable hardware device, such as a field programmable gate array, a programmable array logic, a programmable logic device, etc.

[0168] The above exemplary embodiments are described with reference to the accompanying drawings, and many different forms and embodiments are feasible without departing from the spirit and teachings of the present invention. Therefore, the present invention should not be constructed as a limitation of the exemplary embodiments proposed herein. More specifically, these exemplary embodiments are provided so that the present invention will be perfect and complete, and the scope of the present invention will be conveyed to those who are familiar with the technology. In these figures, the component sizes and relative sizes may be exaggerated for clarity. The terms used here are only based on the purpose of describing specific exemplary embodiments and are not intended to be limiting. As used herein, unless the text clearly indicates otherwise, the singular forms "one", "an" and "the" are intended to include these multiple forms. It will be further understood that the terms "including" and / or "comprising" when used in this specification indicate the presence of the features, integers, steps, operations, components and / or components, but do not exclude the presence or increase of one or more other features, integers, steps, operations, components, components and / or their groups. Unless otherwise indicated, when stated, a range of values ​​includes the upper and lower limits of that range and any subranges therebetween.

[0169] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
