The base station is not limited to a specific technical term, and it should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0083] The core network device can also be referred to as a core network node, a core network function, or a core network network element, etc., which includes but is not limited to at least one of the following: a mobility management entity (MME), an access and mobility management function (AMF), a session management function (SMF), a user plane function (UPF), a policy control function (PCF), a policy and charging rules function (PCRF), an edge application server discovery function (EASDF), a unified data management (UDM), a unified data repository (UDR), a home subscriber server (HSS), a centralized network configuration (CNC), a network repository function (NRF), a network exposure function (NEF), a local NEF (L-NEF), a binding support function (BSF), an application function (AF), a location management function (LMF), a gateway mobile location center (GMLC), a network data analytics function (NWDAF), etc. It should be noted that only the core network device in the NR system is taken as an example for introduction in the embodiments of the present application, and the specific type of the core network device is not limited.

[0084] Optionally, the core network device can be implemented by one or more function modules in one device, or can be implemented by multiple devices together, and the embodiments of the present application do not make a specific limitation hereon. It can be understood that the above function modules can be network elements in a hardware device, can be software function modules running on a dedicated hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0085] As shown in FIG. 1, the ground terminal is located near the ground. Due to the shielding of buildings and vegetation, the ground terminal mainly transmits in a non-line-of-sight manner to the base station, the number of adjacent areas receiving signals is relatively small, the signal strength of the serving cell and the adjacent area is greatly different, and thus the downlink interference of the ground adjacent area to the ground terminal and the uplink interference of the terminal to the ground adjacent area are relatively controllable. The terminal (for example, the unmanned aerial vehicle terminal) is higher than the ground terminal in the flight stage, and can pass through the shielding of buildings, vegetation and the like. Therefore, the terminal (for example, the unmanned aerial vehicle terminal) mainly transmits in a line-of-sight manner in the low altitude, can receive signals of more adjacent areas, and the signal strength difference between the serving cell and the adjacent area is not large, resulting in large downlink interference of the ground adjacent area to the ground terminal and large uplink interference of the terminal (for example, the unmanned aerial vehicle terminal) to the ground adjacent area.

[0086] In the present application, in order to solve the problem of how to flexibly configure the power control parameter of the terminal to avoid large uplink interference of the terminal to the ground adjacent area, a communication processing method, device, equipment and readable storage medium are provided.

[0087] Referring to FIG. 3, the embodiments of the present application provide a communication processing method applied to a terminal, and the specific steps include step 31.

[0088] Step 31: The terminal acquires first information, and the first information is used to indicate multiple sets of configurations of power control parameters; wherein the multiple sets of configurations of the power control parameters are associated to different values of feature information.

[0089] The power control parameter includes at least one of the following: target received power, partial path loss compensation factor, maximum transmission power, and path loss factor.

[0090] The feature information includes at least one of the following: terminal position related information, terminal height related information, terminal type, terminal capability information, terminal moving speed related information, terminal uplink interference information, signal strength information of multiple cells detected by the terminal, and number of LOS cells detected by the terminal.

[0091] Optionally, the first information can be agreed by a protocol or sent by a network side, that is, the multiple sets of configurations of the power control parameter indicated by the first information can be obtained by an agreement of a protocol or can be obtained by receiving the first information sent by the network side.

[0092] Optionally, the first information comprises at least one of the following: a plurality of sets of configurations of the power control parameter, indexes of the plurality of sets of configurations of the power control parameter.

[0093] In this embodiment, the terminal can obtain a plurality of configurations of the power control parameter by obtaining the first information, which are associated with different values of the feature information. In this way, the terminal can select the associated configuration of the power control parameter according to the value of the feature information, and realize flexible adjustment of the transmission power. This dynamic adaptation capability enables the terminal to effectively cope with different network environments and conditions, thereby optimizing the communication quality and improving the reliability and efficiency of signal transmission. In addition, through reasonable power control, the terminal can reduce interference and improve the overall user experience.

[0094] Optionally, the configuration comprises at least one of the following: a power control parameter value, a power control parameter differential value, a power control parameter adjustment value, an index of the power control parameter value, an index of the power control parameter differential value, and an index of the power control parameter adjustment value. Optionally, at least one of the configurations in the plurality of configurations is different. The above-mentioned power control parameter value can be used to calculate the transmission power, for example, the power control parameter value can comprise at least one of the following: a target received power value, a partial path loss compensation factor value, a maximum transmission power value, and a path loss factor value. It can be understood that the power control parameter can be an original power control parameter value or a target power control parameter value, wherein the original power control parameter value can be used to determine the target power control parameter value together with the power control parameter differential value or the power control parameter adjustment value. Taking the calculation of the partial path loss compensation factor value as an example: α = α' + DELTA', wherein α represents the target partial path loss compensation factor value, α' represents the original partial path loss compensation factor value, and DELTA' represents the power control parameter differential value or the power control parameter adjustment value.

[0095] The above-mentioned power control parameter differential value refers to the change amount between the previously used power control parameter, and the power control parameter differential value can be used to determine the target power control parameter value together with the previously used power control parameter value of the terminal.

[0096] The above-mentioned power control parameter adjustment value is used to represent the increment or decrement of the initial power control parameter value, and the power control parameter adjustment value can be used to determine the target power control parameter value together with the initial power control parameter value.

[0097] The above-mentioned index of the power control parameter value is used to indicate the power control parameter value.

[0098] The above-mentioned index of the power control parameter differential value is used to indicate the power control parameter differential value.

[0099] The above-mentioned index of the power control parameter adjustment value is used to indicate the power control parameter adjustment value.

[0100] Optionally, the multiple sets of configurations of the power control parameter associated to different values of the feature information comprise that each set of configuration in the multiple sets of configurations of the power control parameter is associated to a value of the feature information.

[0101] For example, the first information is used to indicate that the multiple sets of configurations of the power control parameter comprise configuration A, configuration B and configuration C; the configuration A is associated to a value a of feature information 1, the configuration B is associated to a value b of feature information 2, and the configuration C is associated to a value c of feature information 3. The feature information 1, the feature information 2 and the feature information 3 can be the same feature information, or different feature information; the values a, b and c of the feature information can be equal or not equal; at least one content in the configuration A, the configuration B and the configuration C can be different.

[0102] In the embodiment, the feature information comprises at least one of the following:

[0103] 1) terminal position related information;

[0104] Optionally, the terminal position information comprises at least one of the following: absolute position of the terminal, relative position of the terminal, three-dimensional (3D) position information of the terminal, change information of the position of the terminal, position area of the terminal, etc.

[0105] 2) terminal height related information;

[0106] Optionally, the terminal height related information comprises at least one of the following: relative height of the terminal, absolute height of the terminal, change information of the height of the terminal, height interval of the terminal, etc.

[0107] 3) terminal type;

[0108] Optionally, the terminal type comprises unmanned aerial vehicle terminal (Unmanned Aerial Vehicle UE, UAV UE) and non-unmanned aerial vehicle terminal (non-UAV UE).

[0109] 4) terminal capability information;

[0110] Optionally, the terminal capability information is used to distinguish the unmanned aerial vehicle terminal and the non-unmanned aerial vehicle terminal.

[0111] 5) terminal moving speed related information;

[0112] Optionally, the manner in which the terminal determines the terminal speed-related information of the terminal includes, but is not limited to, at least one of the following: the terminal can obtain the terminal speed-related information through an inertial measurement unit, a speedometer, or the like; other devices, such as a network-side device, measure the terminal speed-related information and notify the terminal of the terminal speed-related information; or the terminal obtains the terminal speed-related information by detecting a sensing signal or a sensing-integrated signal (for example, a downlink sensing signal transmitted by a base station).

[0113] 6) terminal uplink interference information of the terminal;

[0114] Optionally, the manner in which the terminal determines the terminal uplink interference information of the terminal includes, but is not limited to, terminal uplink interference information measured by a serving cell base station and notified to the terminal.

[0115] 7) signal strength information of a plurality of cells detected by the terminal;

[0116] Optionally, the signal strength information includes, but is not limited to, reference signal receiving power (RSRP).

[0117] In this embodiment, the signal strength information of different cells can be associated with different configurations of power control parameters. For example, the network-side device configures a terminal with a neighbor cell signal strength threshold, and the number of cells higher than the threshold N is associated with a configuration of power control parameters. For example, when the number of cells higher than the threshold is less than 3, a configuration A of power control parameters is associated, when the number of cells higher than the threshold is 3 to 6, a configuration B of power control parameters is associated, and so on. The configuration B of power control parameters can instruct the terminal to use a smaller transmission power, thereby reducing interference to other neighbor cells.

[0118] 8) the number of line-of-sight (LOS) cells detected by the terminal.

[0119] Optionally, the LOS cell includes a cell in which the signal propagation path between the base station and the user equipment has no obstacles (such as buildings, trees, or the like) and can directly transmit signals in the line of sight.

[0120] In this embodiment, different numbers of LOS cells can be associated with different configurations of power control parameters. For example, the network-side device configures a terminal with a LOS cell quantity threshold, and the number of cells higher than the threshold M is associated with a configuration of power control parameters. For example, when the number of cells higher than the threshold is less than 3, a configuration C of power control parameters is associated, when the number of cells higher than the threshold is 3 to 6, a configuration D of power control parameters is associated, and so on. The configuration D of power control parameters can instruct the terminal to use a smaller transmission power, thereby reducing interference to other neighbor cells.

[0142] Optionally, the terminal determines the first configuration of the power control parameter according to a function related to the characteristic information of the terminal.

[0143] Specifically, the first configuration of the power control parameter can be calculated by a function related to the characteristic information of the terminal, for example, the first configuration of the power control parameter = function (the characteristic information of the terminal).

[0144] It can be understood that the expression form of the function is not limited in the embodiment, and the function can include but is not limited to a linear function, a nonlinear function, an empirical formula, an adaptive algorithm, or a machine learning model, etc.

[0149] Optionally, the first information can also indicate the second configuration, that is, the terminal can obtain the second configuration through the first information.

[0150] In the embodiment, by combining the first configuration and the second configuration, the terminal can more accurately determine the transmission power. This accurate control helps to maintain appropriate signal strength under different conditions, and through reasonable power control, the terminal transmission power is adjusted to the best level, avoiding excessive power causing interference to adjacent users.

[0159] In the embodiment, by introducing the second information, the network side can more flexibly configure the power control parameter of the terminal, so that the terminal can quickly make adjustment under the changing network condition, and further reduce potential interference.

[0160] It should be noted that the first information and the second information can be carried in the same information element (IE) to reduce signaling overhead, or the first information and the second information are carried by different information elements respectively. For example, at least one first information and at least one second information are carried in information element A, or at least one first information is carried in information element A, and at least one second information is carried in information element B. Optionally, the information element can be a transmission configuration indicator state (TCI-State).

[0175] In the present embodiment, the network-side device configures multiple configurations of the power control parameter for the terminal through the first information, and the configurations are respectively associated with different values of the feature information. In this way, the terminal can select the associated configuration of the power control parameter according to the value of the feature information, and flexibly adjust the transmission power.

[0176] The embodiments of the present application are described below in combination with Embodiment One to Embodiment Four.

[0177] Embodiment One: The configuration of the uplink power control parameter is associated with the terminal location related information or the terminal height related information.

[0178] Step 1: The terminal determines the feature information of the terminal.

[0179] Optionally, the terminal feature information comprises at least one of the following:

[0180] (1) terminal position related information;

[0181] For example, the terminal position related information comprises at least one of the following: absolute position of the terminal, relative position of the terminal, 3D position information of the terminal, position change information of the terminal, and feature information of the terminal.

[0182] (2) terminal height related information;

[0183] For example, the terminal height related information comprises at least one of the following: relative height of the terminal, absolute height of the terminal, height change information of the terminal, and height interval of the terminal.

[0184] Optionally, the method for the terminal to determine the terminal position related information or the terminal height related information can be any one of the following:

[0185] (1) the terminal determines the terminal position related information of the terminal according to detection of at least one of the following: downlink positioning signals, other reference signals, sensing signals, and integrated sensing signals;

[0186] (2) the terminal determines the terminal position related information of the terminal according to a Global Navigation Satellite System (GNSS) module;

[0187] (3) the terminal determines the terminal height related information of the terminal according to an altimeter or other sensors.

[0188] Step 2: the terminal receives first information sent by the base station; wherein the first information is used to indicate multiple sets of configurations of uplink power control parameters, and the multiple sets of configurations of uplink power control parameters are associated with different terminal position related information or terminal height related information.

[0189] For example, the uplink power control parameters have different values, and the different values are associated with different terminal position related information or terminal height related information.

[0190] Optionally, the uplink power control parameters comprise at least one of the following: P0, a, P-MAX, and PLoffset.

[0191] Optionally, the uplink power control parameters are defined by a protocol or determined by the terminal according to the received first information.

[0192] Optionally, the network side device sends the first information to the terminal through RRC signaling.

[0193] Step 3: the terminal determines a first configuration of the uplink power control parameters according to the terminal position related information or the terminal height related information of the terminal.

[0194] Optionally, the terminal can determine the first configuration of the uplink power control parameter according to the terminal position related information or the height related information of the terminal within a period of time (equivalent to time domain filtering).

[0195] For example, the terminal is located in the relevant position interval or height interval within the T1 time window, and the first configuration of the corresponding uplink power control parameter is selected; or the number of samples in which the terminal is located in the relevant position interval or height interval exceeds N (M>N, M and N are positive integers) in M samples, and the first configuration of the corresponding uplink power control parameter is selected.

[0196] In this embodiment, time domain filtering allows the system to dynamically adjust the power control parameter according to historical data and trends (such as position or height), so as to more reasonably set the uplink power, instead of relying only on the current instantaneous measurement value. This way reduces the frequent fluctuations in power caused by unpredictable changes in the environment, and prevents the ping-pong effect from being sampled multiple times in time or time domain filtering.

[0197] Step 4: The terminal determines the transmission power of the first signal according to the first configuration of the uplink power control parameter, and transmits the first signal.

[0198] Optionally, the first signal includes but is not limited to at least one of a communication signal, a sensing signal, a sensing-communication integrated signal, and a data signal.

[0199] In this embodiment, the terminal can determine the associated power control parameter and the first configuration of the power control parameter through the terminal position related information or the height related information of the terminal, so that the transmission power when the terminal is located at a higher position is relatively smaller than the transmission power when the terminal is located at a lower position, thereby reducing the uplink interference.

[0200] Embodiment two: The configuration of the uplink power control parameter is associated with at least one of the following: terminal type, terminal capability information, terminal moving speed related information, terminal uplink interference information, signal strength information of multiple cells detected by the terminal, and the number of cells satisfying the line-of-sight detected by the terminal.

[0204] Optionally, the terminal type includes but is not limited to UAV UE and non-UAV UE.

[0205] (2) terminal capability information;

[0206] For example, the terminal capability information is used to distinguish whether the terminal is a UAV UE or a non-UAV UE.

[0207] (3) terminal moving speed related information;

[0208] Optionally, the terminal obtains the moving speed related information of the terminal according to an inertial measurement unit, a speedometer, or the like, or other devices such as a network side device measure the moving speed related information of the terminal and notify the terminal, or the terminal obtains the moving speed related information of the terminal by detecting a sensing signal or a sensing-integrated signal (for example, a downlink sensing signal sent by a base station).

[0209] (3) terminal uplink interference information;

[0210] Optionally, the terminal uplink interference information can be measured by a serving cell of the terminal and notified to the terminal.

[0211] (4) signal strength information of multiple cells detected by the terminal;

[0212] (5) the number of LOS cells detected by the terminal, that is, there is an LOS path between the terminal and the cell.

[0213] Step 2: The terminal receives first information sent by the base station; wherein the first information is used to indicate multiple sets of configurations of uplink power control parameters, and the multiple sets of configurations of uplink power control parameters are associated with different feature information.

[0214] For example, the uplink power control parameters have different values, and the different values are associated with different feature information.

[0215] Optionally, the uplink power control parameters include at least one of the following: P0, a, P-MAX, and PLoffset.

[0216] Step 3: The terminal determines a first configuration of the uplink power control parameters according to the feature information of the terminal.

[0217] Optionally, the terminal can determine the first configuration of the uplink power control parameters according to the feature information in a period of time (equivalent to time domain filtering); for example, when the UE satisfies the target feature information (for example, the moving speed is greater than 20Km / h) in a T1 time window, the corresponding first configuration of the uplink power control parameters is selected; or when the number of sample points of the terminal that satisfy the target feature information exceeds N out of M sample points (M>N, M and N are positive integers), the corresponding first configuration of the uplink power control parameters is selected.

[0218] In the embodiment, the time domain filtering allows the system to dynamically adjust the first configuration of the uplink power control parameters according to the historical data and trends (such as position or height), so as to more reasonably set the uplink power, instead of only relying on the current instantaneous measurement value. In this way, the frequent fluctuations of the power caused by unpredictable changes in the environment are reduced.

[0219] Step 4: The terminal determines the transmission power of the first signal according to the first configuration of the uplink power control parameters, and transmits the first signal.

[0220] Optionally, the first signal includes at least one of a communication signal, a sensing signal, a sensing-communication integrated signal, and a data signal.

[0221] In the embodiment, by configuring different first configurations of the power control parameters for different types of terminals, or configuring the first configuration of the power control parameters for the UAV terminal in association with the terminal moving speed or the uplink interference or the multi-cell signal strength distribution or the number of LOS cells, the uplink transmission power of the terminal when the terminal is at a higher position is relatively smaller than the uplink transmission power when the terminal is at a lower position, and the uplink interference is reduced.

[0276] In one embodiment, the PLoffset value is calculated as a function of terminal location related information or terminal height related information, i.e., PLoffset = function (terminal location related information) or PLoffset = function (terminal height related information).

[0277] In this embodiment, a preferable configuration is that the higher the UE location or height, the smaller the value of PLoffset, for example, the value of PLoffset is always 0 or negative.

[0278] In another embodiment, the UE can calculate the transmission power of the first signal according to Formula Two:

[0279] Tx Power = MAX{P-MAX, (Target Rx Power + a Path Loss factor + RB factor)}; (Formula Two)

[0280] 1) RB factor: the bandwidth occupied by the second signal, for example, the number of RBs;

[0281] For example, RB factor = 10log 10 (2 μ M RB，b，f，c (i)), where M RB，b，f，c (i) is the number of RBs of the second signal at time i, which, in combination with SCS, determines the total bandwidth of the second signal, M RB，b，f，c (i) is defined for a bandwidth part BWP (b), a carrier (f) and a cell (c); μ is related to the subcarrier spacing and can take values 0, 1, 2, 3, etc., corresponding to subcarrier spacing of 15 KHz, 30 KHz, 60 KHz and 120 KHz, respectively;

[0282] 2) M RB，b，f，c (i) is the number of RBs spanned by the second signal;

[0283] In one embodiment, RB factor is brought into Formula Two, and Formula Two becomes:

[0284] Tx Power = MAX{P-MAX, (Target Rx Power + Path Loss factor + 10log 10 (2 μ M RB，b，f，c (i))}.

[0285] In yet another embodiment, the terminal calculates the transmission power of the first signal according to Formula Three or Formula Four.

[0286] wherein Formula Three and Formula Four are respectively based on Formula One and Formula Two with an additional term: Power Control Command.

[0287] Tx Power = MAX{P-MAX, (Target Rx Power + Path Loss factor + Power Control Command)}; (Formula Three)

[0288] Tx Power = MAX{P-MAX, (Target Rx Power + Path Loss factor + RB factor + Power Control Command)}; (Formula Four)

[0289] wherein Power Control Command is a power control parameter adjustment value or a power control parameter differential value informed by the base station to the UE, for example, represented by 2 bits of Downlink Control Information (DCI):

[0290] Table 16:

[0291] It can be understood that other parameters can also be introduced in the above Formula One, Formula Two, Formula Three or Formula Four, for example, a factor related to Modulation and Coding Scheme (MCS) in NR power control.

[0292] In an implementation, after the UE determines the transmission power of the first signal according to Formula One, Formula Two, Formula Three or Formula Four, the UE reports information related to the transmission power (such as the power absolute value of the transmission power, or the power headroom of the transmission power) to the base station.

[0293] Embodiment Four

[0294] In an implementation, the UE calculates the transmission power Tx Power of the first signal according to Formula Five:

[0295] Tx Power = MAX{P-MAX, (Target Rx Power + a PathLoss factor)}; (Formula Five)

[0296] wherein Tx Power: the transmission power of the first signal;

[0297] P-MAX: the maximum transmit power of the terminal, the total transmit power of the terminal at any time shall not exceed P-MAX;

[0298] Target Rx Power: target receive power;

[0299] α: a partial path loss compensation factor, which can be set as an optional item; generally, the value is between 0 and 1, and the uplink inter-cell interference on the same frequency can be alleviated through the partial path loss compensation factor.

[0300] Optionally, the target receive power can be calculated by the following formula:

[0301] P0 = P0' + DELTA;

[0302] Wherein, P0 is the value of the target receive power, P0' can be the original value of the target receive power, for example, the original value of the target receive power can be a parameter configured by the base station through RRC signaling, for example, the P0' configured by the base station is greater than -100 dBm.

[0303] DELTA is a power control parameter adjustment value or a power control parameter differential value (or adjustment factor), which is associated with terminal type or terminal moving speed related information or terminal uplink interference information or terminal detected multiple cell signal strength information or the number of LOS cells detected by the UE; the DELTA value associated with the terminal type or terminal moving speed related information or terminal uplink interference information or terminal detected multiple cell signal strength information or the number of LOS cells detected by the UE (Tables 17 to 21) is defined by the protocol or configured by the network side.

[0304] Table 17: DELTA value associated with terminal type.

[0307] Table 20: DELTA value associated with UE detected multiple cell signal strength information.

[0308] Table 21: DELTA value associated with the number of LOS cells detected by the UE

[0310] In this embodiment, the DELTA value of a UAV UE is smaller than that of a non-UAV UE; or the larger the terminal speed (or the higher the terminal altitude), the smaller the DELTA value; or the larger the terminal uplink interference information (or the higher the terminal altitude), the smaller the DELTA value; or the smaller the signal strength difference of multiple cells detected by the terminal (or the higher the terminal altitude), the smaller the DELTA value; or the larger the number of LOS cells detected by the terminal (or the higher the terminal altitude), the smaller the DELTA value.

[0311] In another embodiment, DELTA is not defined (DELTA = 0), but different values of P0 are defined for different terminal types or terminal speed related information or terminal uplink interference information or signal strength information of multiple cells detected by the terminal or number of LOS cells detected by the terminal, for example, Tables 22 to 26:

[0318] In this embodiment, the P0 value of the UAV UE is smaller than the P0 value of the non-UAV UE; or the greater the terminal moving speed (the greater the possibility of the terminal being in high altitude), the smaller the P0 value; or the greater the terminal uplink interference information (the greater the possibility of the terminal being in high altitude), the smaller the P0 value; or the smaller the signal strength difference of multiple cells detected by the terminal (the greater the possibility of the UE being in high altitude), the smaller the P0 value; or the greater the number of LOS cells detected by the terminal (the greater the possibility of the terminal being in high altitude), the smaller the P0 value.

[0319] In an embodiment, a = a' + DELTA'; where a' is the original value of the partial path loss compensation factor configured by the base station for the terminal. DELTA' is the power control parameter adjustment value or the power control parameter differential value (or adjustment factor), which is associated with the terminal type or terminal moving speed related information or terminal uplink interference information or signal strength information of multiple cells detected by the terminal or the number of LOS cells detected by the UE; the DELTA' value associated with the terminal type or terminal moving speed related information or terminal uplink interference information or signal strength information of multiple cells detected by the terminal or the number of LOS cells detected by the UE (Tables 27 to 31) is defined by the protocol or configured by the network side.

[0323] Table 30: DELTA' value associated with signal strength information of multiple cells detected by the terminal.

[0324] Table 31: DELTA' value associated with the number of LOS cells detected by the terminal

[0325] In one embodiment, DELTA' is calculated as a function of terminal speed related information or terminal uplink interference information or signal strength information of multiple cells; i.e., DELTA' = function (terminal speed related information) or DELTA' = function (terminal uplink interference information) or DELTA' = function (signal strength information of multiple cells).

[0327] In another embodiment, different terminal types or terminal speed related information or terminal uplink interference information or signal strength information of multiple cells detected by the terminal or the number of LOS cells detected by the terminal define different values of a, for example, Tables 32 to 36:

[0333] In another embodiment, a is calculated as a function of terminal speed related information or terminal uplink interference information or signal strength information of multiple cells; i.e., a = function (terminal speed related information) or a = function (terminal uplink interference information) or a = function (signal strength information of multiple cells).

[0334] In the embodiment, the α value of the UAV UE is smaller than the α value of the non-UAV UE; or, the greater the terminal moving speed (the greater the possibility of the terminal being located in the high altitude), the smaller the α value; or, the greater the terminal uplink interference information (the greater the possibility of the terminal being located in the high altitude), the smaller the α value; or, the smaller the difference of the signal strengths of the multiple cells detected by the terminal (the greater the possibility of the terminal being located in the high altitude), the smaller the α value; or, the greater the number of the LOS cells detected by the terminal (the greater the possibility of the terminal being located in the high altitude), the smaller the α value.

[0335] Optionally, P-MAX = P-MAX' + DELTA"; wherein, P-MAX is the maximum transmission power limited by the actual capability of the terminal. DELTA" is a power control parameter adjustment value or a power control parameter differential value (or referred to as an adjustment factor), which is associated with the terminal type or terminal moving speed related information or terminal uplink interference information or terminal detected multiple cell signal strength information or the number of the LOS cells detected by the terminal. The DELTA" value associated with the terminal type or terminal moving speed related information or terminal uplink interference information or terminal detected multiple cell signal strength information or the number of the LOS cells detected by the terminal (Table 37 to Table 41) is defined by the protocol or configured by the network side.

[0339] Table 40: DELTA" value associated with terminal detected multiple cell signal strength information.

[0340] Table 41: DELTA" value associated with the number of the LOS cells detected by the terminal

[0341] In an implementation, DELTA" is calculated as a function of the terminal moving speed related information or the terminal uplink interference information or the multiple cell signal strength information; that is, DELTA" = function (terminal moving speed related information); or, DELTA" = function (terminal uplink interference information); or, DELTA" = function (multiple cell signal strength information).

[0342] In this embodiment, the DELTA" value of the UAV UE is smaller than the DELTA" value of the non-UAV UE; or, the greater the terminal moving speed (the greater the possibility of the terminal being at high altitude), the smaller the DELTA" value; or, the greater the terminal uplink interference information (the greater the possibility of the terminal being at high altitude), the smaller the DELTA" value; or, the smaller the signal strength difference of the multiple cells detected by the terminal (the greater the possibility of the terminal being at high altitude), the smaller the DELTA" value; or, the greater the number of LOS cells detected by the terminal (the greater the possibility of the terminal being at high altitude), the smaller the DELTA" value.

[0343] In another embodiment, the terminal type or terminal moving speed related information or terminal uplink interference information or signal strength information of multiple cells detected by the terminal or the number of LOS cells detected by the UE defines different values of P-MAX, for example, Table 42 to Table 46:

[0347] Table 45: P-MAX value associated with signal strength information of multiple cells detected by the terminal

[0348] Table 46: P-MAX value associated with the number of LOS cells detected by the terminal

[0349] In another embodiment, P-MAX is calculated as a function of terminal moving speed related information or terminal uplink interference information or signal strength of multiple cells; that is: P-MAX = function (terminal moving speed related information); or, P-MAX = function (terminal uplink interference information); or, P-MAX = function (signal strength information of multiple cells).

[0350] In the embodiment, the P-MAX value of the UAV UE is smaller than the P-MAX value of the non-UAV UE; or, the greater the UE moving speed (the greater the possibility of the UE being located in the high altitude), the smaller the P-MAX value; or, the greater the UE uplink interference (the greater the possibility of the UE being located in the high altitude), the smaller the P-MAX value; or, the smaller the difference of the signal strengths of the multiple cells detected by the UE (the greater the possibility of the UE being located in the high altitude), the smaller the P-MAX value; or, the greater the number of the LOS cells detected by the UE (the greater the possibility of the UE being located in the high altitude), the smaller the P-MAX value.

[0351] Optionally, the Path Loss factor is determined by the following formula:

[0352] Path Loss factor = reference signal power - first index + PLoffset

[0353] wherein,

[0354] 1) the first index is the received signal strength obtained by the UE measuring the second signal, for example, RSRP;

[0355] 2) the reference signal power is the transmission power of the second signal, and the reference signal power is informed to the terminal by the base station, for example, the base station broadcasts through SIB signaling; the second signal can be a signal transmitted by the base station, for example, a synchronization signal, a CSI-RS, or other signals, etc.

[0356] 3) the PLoffset is a power control parameter adjustment value or a power control parameter differential value (or referred to as a correction value) of the Path Loss factor, which is equivalent to a power control parameter adjustment value or a power control parameter differential value of the first index. For the convenience of description, it is regarded as a power control parameter adjustment value or a power control parameter differential value of the Path Loss factor. The Path Loss factor is associated with the terminal type or terminal moving speed related information or terminal uplink interference information or terminal detected multiple cell signal strength information or the number of the LOS cells detected by the UE; the terminal type or terminal moving speed related information or terminal uplink interference information or terminal detected multiple cell signal strength information or the number of the LOS cells detected by the UE corresponds to the value (Tables 47-51) of the PLoffset, which is defined by the protocol or configured by the network side.

[0360] Table 50: PLoffset value associated with signal strength information of multiple cells detected by terminal

[0361] Table 51: PLoffset value associated with the number of LOS cells detected by UE

[0362] In the embodiment, the PLoffset value of the UAV UE is smaller than the PLoffset value of the non-UAV UE; or, the greater the terminal moving speed (the greater the possibility of the terminal being located in the high altitude), the smaller the value of the PLoffset; or, the greater the terminal uplink interference information (the greater the possibility of the terminal being located in the high altitude), the smaller the value of the PLoffset; or, the smaller the signal strength difference of multiple cells detected by the terminal (the greater the possibility of the terminal being located in the high altitude), the smaller the value of the PLoffset; or, the greater the number of LOS cells detected by the terminal (the greater the possibility of the terminal being located in the high altitude), the smaller the value of the PLoffset.

[0363] In another implementation, the UE can calculate the transmission power of the first signal according to Formula Six:

[0364] Tx Power = MAX{P-MAX, (Target Rx Power + a PathLoss factor + RB factor)}; (Formula Six)

[0365] Wherein, RB factor: the bandwidth occupied by the second signal, for example, the number of RBs;

[0366] For example, RB factor = 10log 10 (2 μ M RB，b，f，c (i)) where M RB，b，f，c (i) is the number of RBs of the second signal at time i, in combination with the SCS subcarrier spacing, the total bandwidth of the first signal is determined, M RB，b，f，c (i) is defined for bandwidth part BWP (b), carrier (f) and cell (c); μ is related to the subcarrier spacing, which can take values 0, 1, 2, 3, etc., corresponding to subcarrier spacing of 15KHz, 30KHz, 60KHz and 120KHz, respectively; M RB，b，f，c(i) is the number of RBs across which the first signal spans.

[0367] Bringing the RB factor into Equation Six, Equation Six becomes: Tx Power = MAX{P-MAX, (Target Rx Power + PathLoss factor + 10log 10 (2 μ M RB，b，f，c (i)))}.

[0368] In yet another embodiment, the UE calculates the transmit power of the first signal according to Equation Seven or Equation Eight, which adds a term: Power Control Command, to Equation Five and Equation Six respectively.

[0369] Tx Power = MAX{P-MAX, (Target Rx Power + PathLoss factor + Power Control Command)}; (Equation Seven)

[0370] Tx Power = MAX{P-MAX, (Target Rx Power + PathLoss factor + RB factor + Power Control Command)}; (Equation Eight)

[0371] Where Power Control Command is a power control parameter adjustment value or a power control parameter differential value informed by the base station to the UE, for example, represented by two bits of DCI:

[0372] Table 52:

[0373] It can be understood that other parameters may also be introduced in Equation Five, Equation Six, Equation Seven or Equation Eight, for example, a factor related to MCS (Modulation and Coding Scheme) in NR power control.

[0374] In an embodiment, after the UE determines the transmit power of the first signal according to Equation One, Equation Two, Equation Three or Equation Four, the UE reports the relevant information of the transmit power (such as the power absolute value of the transmit power, or the power headroom of the transmit power) to the base station.

[0375] Embodiment Five: Configuration method or signaling design of power control parameter associated with the first feature information.

[0376] The UE can determine the transmit power of the first signal and perform power control in one of the following ways.

[0377] 1) Mode 1:

[0378] (i) The second configuration of power control parameters irrelevant to the terminal's feature information is defined by the protocol or signaling, for example, the second configuration includes multiple sets of P0, a, and their indexes, and the second configuration of power control parameters itself does not contain the content related to the feature information.

The terminal determines the configuration of the power control parameters associated with the terminal's feature information from the multiple sets of feature information and their associated configurations of power control parameters indicated by the IE as the first configuration.

[0380] (iii) The terminal determines the transmission power of the first signal according to the first configuration, or the terminal determines the transmission power of the first signal according to the first configuration and the second configuration.

[0381] 2) Mode 2:

[0382] (i) The second configuration of power control parameters irrelevant to the terminal's feature information is defined by the protocol or signaling, for example, the second configuration includes multiple sets of P0, a, and their indexes.

[0383] (ii) When the power control related parameters are configured by signaling, the multiple sets of feature information and their associated configurations of power control parameters are indicated in the information element (IE) carrying the power control parameters; for example, the configuration can be an index in the second configuration. Optionally, the configuration of power control parameters associated with one feature information is the original power control parameter value, and the configurations of power control parameters associated with other feature information are used to indicate the power control parameter difference value or the power control parameter adjustment value of the power control parameter, reducing the signaling overhead. The terminal determines the configuration of the power control parameters associated with the terminal's feature information from the multiple sets of feature information and their associated configurations of power control parameters indicated by the IE as the first configuration.

[0384] (iii) The terminal determines the transmission power of the first signal according to the first configuration, or the terminal determines the transmission power of the first signal according to the first configuration and the second configuration.

[0385] 3) Mode 3:

[0386] (i) The second configuration of power control parameters irrelevant to the terminal's feature information is defined by the protocol or signaling, for example, the second configuration includes multiple sets of P0, a, and their indexes.

[0387] (ii) the network configures the UE with multiple sets of information elements (IEs) of the power control parameters of the bearers, each set of the IEs indicates one feature information and one corresponding configuration of the power control parameters such as the index of P0 and a, and the multiple sets of the IEs respectively indicate different feature information. Optionally, the configuration of the power control parameters carried in one IE is used to indicate the original value of the power control parameters, and the configurations of the power control parameters carried in other IEs are used to indicate the differential value or the adjustment value of the power control parameters, so as to reduce the signaling overhead. The UE matches one set of the IEs of the power control parameters according to the feature information of the terminal, and the power control parameters carried in the IE are used as the first configuration.

[0388] (iii) the terminal determines the transmission power of the first signal according to the first configuration, or the terminal determines the transmission power of the first signal according to the first configuration and the second configuration.
