[0042] Please refer to Figure 1 This illustration shows a schematic diagram of a mobile communication system provided in one embodiment of this application. The mobile communication system can be a 5G system, also known as an NR system. The mobile communication system includes: an access network device 120 and a terminal 140.

[0043] Access network device 120 can be a base station. For example, a base station can be a gNB (gN) in a 5G system using a centralized-distributed architecture. When access network device 120 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DU). The central unit is equipped with a protocol stack of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) layers; the distributed units are equipped with a physical (PHY) layer protocol stack. This application embodiment does not limit the specific implementation of access network device 120. Optionally, access network device 120 can also include a home eNB (HeNB), a relay, a pico, etc. Access network device 120 can also be referred to as a network-side device.

[0044] Access network device 120 and terminal 140 establish a wireless connection through a wireless air interface. Optionally, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as New Radio (NR); or, the wireless air interface may also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0045] Terminal 140 may be a device that provides voice and / or data connectivity to a user. The terminal may communicate with one or more core networks via a Radio Access Network (RAN), and terminal 140 may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal.

[0046] It should be noted that, in Figure 1 The mobile communication system shown may include multiple access network devices 120 and / or multiple terminals 140. Figure 1 The example shown is an access network device 120 and a terminal 140, but this embodiment is not limited thereto.

[0047] Please refer to Figure 2 This illustration shows a flowchart of a data transmission method provided in an exemplary embodiment of this application. This embodiment applies the method to... Figure 1 The method is illustrated using the terminal described above. The method includes:

[0048] Step 201: The terminal transmits data in the first area using the first power.

[0049] Step 202: The terminal transmits data using the second power in the second area. The first area and the second area are distinguished by transmission resources.

[0050] Optionally, the first region and the second region are logical regions obtained by the access network device by dividing transmission resources, wherein the transmission resources include time-domain resources and / or frequency-domain resources.

[0051] In one possible implementation, the first region and the second region are distinguished using any of the following methods:

[0052] 1. Distinguish between the first and second regions using time-domain resources.

[0053] Optionally, the access network device distinguishes regions based on time-domain resources, wherein the time-domain resources include at least one of symbols, slots, and subframes.

[0054] Optionally, the first region and the second region may each occupy the same or different amounts of time-domain resources.

[0055] For example, when access network devices divide regions according to time slots, they can divide the first time slot in a subframe into the first region and the second time slot in a subframe into the second region.

[0056] Of course, region differentiation can also be based on other types of time-domain resources, and this embodiment does not limit this.

[0057] 2. The first and second regions are distinguished by frequency domain resources.

[0058] Optionally, the access network device distinguishes regions based on frequency domain resources, wherein the frequency domain resources include at least one of Physical Resource Block (PRB) and Resource Block Group (RBG).

[0059] Optionally, the first region and the second region may each occupy the same or different amounts of frequency domain resources.

[0060] For example, when access network devices divide regions according to physical resource blocks, they can divide physical resource blocks 1-50 into the first region and physical resource blocks 51-100 into the second region.

[0061] Of course, the regional configuration can also be based on other types of frequency domain resources, and this embodiment does not limit this.

[0062] 3. The first and second regions are distinguished by time-domain and frequency-domain resources.

[0063] Optionally, in addition to distinguishing regions based solely on frequency domain resources or time domain resources, access network devices can also distinguish regions based on both time domain and frequency domain resources.

[0064] Optionally, the access network device can configure both the first and second regions based on both time slots and physical resource blocks.

[0065] 4. The first and second regions are distinguished by the frequency domain broadband part (BWP).

[0066] BWP refers to a set of contiguous physical resource blocks on a given set of parameters and a given carrier.

[0067] In one possible implementation, the access network device configures at least two BWPs for the terminal on the available bandwidth, each corresponding to a different region. For example, in this embodiment, the access network device configures BWP1 and BWP2 for the terminal, corresponding to the first region and the second region, respectively.

[0068] Optionally, when two BWPs are configured, the time-frequency domain resources corresponding to the two BWPs are different. For example, BWP1 corresponds to PRB1-50, while BWP2 corresponds to PRB51-55; or, the time-frequency domain resources corresponding to the two BWPs are the same, but the corresponding subcarrier spacing is different. For example, both BWP1 and BWP2 correspond to PRB51-55, but the subcarrier spacing corresponding to BWP1 is 60KHz, while the subcarrier spacing corresponding to BWP2 is 15KHz.

[0069] Optionally, this application only illustrates the configuration of two regions as an example. In other possible implementations, at least three regions can be configured. This application does not limit the specific number of regions.

[0070] Optionally, the access network device sends area configuration information indicating the configuration of the first area and the second area to the terminal, so that the terminal can determine the first area and the second area based on the area configuration information.

[0071] Optionally, the area configuration information sent by the access network device can also be used to indicate the distinction between the first area and the second area, as well as the configuration information. For example, when different areas are configured through BWP, the area configuration information includes configuration information such as the BWP subcarrier spacing.

[0072] Optionally, the power parameters of the first power and the second power are configured by the access network equipment. These power parameters can be expressed as actual power values ​​or as power spectral density (PSD).

[0073] In one possible application scenario, under the scheduling of the access network equipment, the terminal transmits service data at low power in the first area, or at high power in the second area. When the terminal transmits high-priority service data under the scheduling of the access network equipment, in order to reduce the transmission latency of the high-priority service data, the terminal chooses to transmit the high-priority service data in the first area through resource preemption, and to ensure transmission reliability, the high-priority service data is transmitted at high power. The low and high power settings can be agreed upon by the protocol or instructed by the access network equipment.

[0074] Optionally, in a practical application scenario, when the above method is applied to the uplink data transmission scenario of eMBB and URLLC services in 5G, the terminal, under the scheduling of the access network equipment, transmits eMBB service data at a first power (i.e., low power) in the first area and transmits eMBB service data at a second power (i.e., normal power) in the second area. When the terminal transmits URLLC service data under the scheduling of the access network equipment, in order to reduce the transmission latency of URLLC service data, the terminal selects the first area and transmits URLLC service data by preempting eMBB service resources. In order to ensure the high reliability of URLLC service, the terminal uses a third power (greater than the first power, the same as or different from the second power) to transmit URLLC service data in the first area.

[0075] In summary, in this embodiment, by configuring different regions on the transmission resources, the terminal can use corresponding power to send data in different regions, thereby avoiding the terminal frequently detecting control signals during uplink data transmission, thus reducing the terminal's power consumption. Furthermore, using different power for data transmission helps improve the reliability and efficiency of data transmission between the terminal and the access network equipment in the communication system.

[0076] Please refer to Figure 3 This illustration shows a flowchart of a data transmission method provided in an exemplary embodiment of this application. This embodiment applies the method to... Figure 1 The method is illustrated using the access network device described above. The method includes:

[0077] Step 301: The access network device transmits data using the first power in the first area.

[0078] Access network equipment distinguishes between the first region and the second region (logical region) by transmission resources, which include time-domain resources and / or frequency-domain resources.

[0079] Optionally, access network devices can distinguish regions in the following ways:

[0080] 1. Distinguish between the first and second regions using time-domain resources.

[0081] 2. The first and second regions are distinguished by frequency domain resources.

[0082] 3. The first and second regions are distinguished by time-domain and frequency-domain resources.

[0083] 4. The first and second regions are distinguished by the frequency domain broadband part (BWP).

[0084] For details on the specific differentiation method, please refer to the description in step 202. This embodiment will not repeat it here.

[0085] Step 302: The access network device transmits data using the second power in the second area, wherein the first area and the second area are distinguished by transmission resources.

[0086] Based on the identified regions, the access network devices transmit downlink data using the corresponding power in the respective regions.

[0087] In one possible implementation, the access network device transmits data at low power in a first area and at high power in a second area.

[0088] Optionally, in a practical application scenario, when the above method is applied to the downlink data transmission scenario of eMBB and URLLC services in 5G, the access network device transmits eMBB service data at a first power (e.g., low power) in the first area and transmits eMBB service data at a second power (e.g., normal power, and higher than the first power) in the second area.

[0089] Optionally, when the access network device needs to schedule URLLC services, in order to reduce the transmission latency of URLLC service data, the access network device selects the first area and sends URLLC service data by preempting eMBB service resources. In order to ensure the high reliability of URLLC services, the access network device uses a third power (greater than the first power, the same as or different from the second power) to send URLLC service data in the first area.

[0090] Optionally, in order to instruct the terminal to send uplink data in a similar manner, the access network device sends area configuration information to the terminal based on the area configuration. The access network device may send the area configuration information via broadcast.

[0091] To enable the terminal to transmit uplink data at appropriate power in different areas, the access network device also indicates the data transmission power in different areas to the terminal. Optionally, the access network device sends the difference between the power parameters of the first power and the power parameters of the second power to the terminal, or the access network device independently configures the power parameters of the first power and the second power.

[0092] Furthermore, under the scheduling of the access network equipment, the terminal transmits data using a first power in the first area and a second power in the second area. Correspondingly, the access network equipment receives the data transmitted by the terminal in the first area and / or the second area.

[0093] Optionally, for received data, the access network device may distinguish the received data based on the length of the Transmission Time Interval (TTI), the Control Resource Set (CORESET), or the Physical Downlink Control Channel Format (PDCCH Format). For example, the access network device may distinguish between eMBB data and URLLC data based on the TTI length. This embodiment does not limit the method by which the access network device distinguishes data types.

[0094] In summary, in this embodiment, by configuring different regions on the transmission resources, the terminal can use corresponding power to send data in different regions, thereby avoiding the terminal frequently detecting control signals during uplink data transmission, thus reducing the terminal's power consumption. Furthermore, using different power for data transmission helps improve the reliability and efficiency of data transmission between the terminal and the access network equipment in the communication system.

[0095] Please refer to Figure 4 This illustrates a flowchart of a data transmission method provided in another exemplary embodiment of this application. This embodiment applies the method to... Figure 1 The method is illustrated using the aforementioned communication system as an example. The method includes:

[0096] Step 401: The access network device sends area configuration information to the terminal. The area configuration information is used to indicate the configuration of the first area and the second area.

[0097] Optionally, the regional configuration information may include: time-domain configuration information, frequency-domain configuration information, or time-frequency-domain configuration information.

[0098] Optionally, the access network device may broadcast area configuration information to each terminal so that each accessing terminal can be aware of the area configuration.

[0099] In one possible implementation, when different regions are configured based on physical resource blocks, the region configuration information sent by the access network device to the terminal can be in the following format: Power_parameter(n_PRB) = {0,1}, where n_PRB is used to indicate the nth physical resource block, 0 indicates that the physical resource block belongs to the first region, and 1 indicates that the physical resource block belongs to the second region.

[0100] Similarly, when configuring different regions based on time slots, the region configuration information sent by the access network device to the terminal can be in the following format: Power_parameter(n_slot)={0,1}, where n_slot is used to indicate the nth time slot, 0 indicates that the time slot belongs to the first region, and 1 indicates that the time slot belongs to the second region.

[0101] To reduce interference between cells and thus improve data transmission quality, in one possible implementation, access network devices exchange area information. Based on the area information of neighboring access network devices, they adjust their own area configuration and send the adjusted area configuration information to the terminal. For example, access network device A sends area configuration information A to access network device B as: Power_parameter(PRB1) = {0}, Power_parameter(PRB2) = {1}. That is, access network device A allocates the first physical resource block to the first area and the second physical resource block to the second area. Access network device B then adjusts its own area configuration information B to Power_parameter(PRB1) = {1}, Power_parameter(PRB2) = {0}.

[0102] Step 402: The terminal receives the area configuration information sent by the access network device.

[0103] Step 403: The access network device sends a power difference value to the terminal. The power difference value is the difference between the power parameters of the first power and the power parameters of the second power.

[0104] To reduce interference when transmitting data in the first and second regions, the terminal needs to transmit data at different power levels in different regions. Accordingly, while indicating the region configuration, the access network device also needs to indicate the data transmission power in different regions to the terminal.

[0105] Optionally, the access network device sends the power difference between the first and second regions to the terminal. This power parameter can be represented by an actual power value or a power spectral density.

[0106] Optionally, the access network device also sends configured power parameters to the terminal, so that the terminal can determine the first power and the second power based on the power parameters and the power difference. The power parameters sent by the access network device include at least one of the following: target received power parameters, path loss compensation coefficient, and dynamic power adjustment value.

[0107] Optionally, the power parameters include the following configuration options.

[0108] 1. The path loss compensation coefficient in the power parameters is configured independently, while the target received power parameter and dynamic power adjustment value in the power parameters are configured together.

[0109] When this configuration method is adopted, the access network equipment configures its own path loss compensation coefficient for each area, and configures a unified target received power parameter and dynamic power adjustment value for each area. That is, different areas have different path loss compensation coefficients, but have the same target received power parameter and dynamic power adjustment value.

[0110] 2. The path loss compensation coefficient and dynamic power adjustment value in the power parameters are configured independently, while the target received power parameter in the power parameters is configured in a shared manner.

[0111] When this configuration method is adopted, the access network equipment configures its own path loss compensation coefficient and dynamic power adjustment value for each area, and configures a unified target received power parameter for each area. That is, different areas have different path loss compensation coefficients and dynamic power adjustment values, but have the same target received power parameter.

[0112] 3. The dynamic power adjustment value in the power parameters is configured independently, while the target received power parameter and the path loss compensation coefficient in the power parameters are configured together.

[0113] When this configuration method is adopted, the access network equipment configures its own dynamic power adjustment value for each area, and configures a unified target received power parameter and path loss compensation coefficient for each area. That is, different areas have different dynamic power adjustment values, but have the same target received power parameter and path loss compensation coefficient.

[0114] When configuring power parameters using the three methods described above, power control can be differentiated for different scenarios, services, and data types, and the signaling overhead when configuring power parameters can be reduced (due to the existence of shared configuration).

[0115] 4. The dynamic power adjustment value in the power parameters, the target received power parameters, and the path loss compensation coefficient are all shared in the configuration.

[0116] When this configuration method is adopted, the access network equipment configures the same target received power parameters, path loss compensation coefficient and dynamic power adjustment value for each area, that is, different areas have the same target received power parameters, path loss compensation coefficient and dynamic power adjustment value.

[0117] When configuring power parameters in this way, the signaling overhead is minimized because different areas share the configuration parameters. Subsequently, the terminal performs differentiated power control based on the power differences configured by the access network equipment, taking into account different scenarios, services, and data types.

[0118] 5. The target received power parameter and the path loss compensation coefficient in the power parameters are configured independently, while the dynamic power adjustment value in the power parameters is configured in a shared manner.

[0119] When this configuration method is adopted, the access network equipment configures its own target received power parameters and path loss compensation coefficients for each area, and the dynamic power adjustment value is shared by each area. That is, different areas have different target received power parameters and different path loss compensation coefficients, but have the same dynamic power adjustment value.

[0120] This configuration method allows for differentiated power control based on different scenarios, services, and data types. Furthermore, it enables real-time tracking of channel changes based on shared dynamic power adjustment values.

[0121] 6. The target received power parameter, path loss compensation coefficient, and dynamic power adjustment value in the power parameters can be configured independently.

[0122] When this configuration method is adopted, the access network equipment configures its own target received power parameters, path loss compensation coefficient and dynamic power adjustment value for each area. That is, different areas have different target received power parameters, different path loss compensation coefficients and different dynamic power adjustment values.

[0123] By adopting this configuration method, since each region has its own power parameters, more precise power control can be performed for different scenarios, services and data types (but the signaling overhead also increases accordingly).

[0124] 7. The target received power parameter in the power parameters is configured independently, while the path loss compensation coefficient and dynamic power adjustment value in the power parameters are configured together.

[0125] When this configuration method is adopted, the access network equipment configures its own target received power parameters for each area, and configures a unified dynamic power adjustment value and path loss compensation coefficient for each area. That is, different areas have different target received power parameters, but have the same dynamic power adjustment value and different path loss compensation coefficients.

[0126] This configuration method allows for independent configuration of the target received power, enabling immediate power control tailored to different scenarios, services, and data types, while reducing the signaling overhead of configuring power parameters.

[0127] 8. The target received power parameter and dynamic power adjustment value in the power parameters are configured independently, while the path loss compensation coefficient in the power parameters is configured in a shared manner.

[0128] In this configuration method, the access network equipment configures its own target received power parameters and dynamic power adjustment values ​​for each area, and sets a uniform path loss compensation coefficient for each area. That is, different areas have different target received power parameters and different dynamic power adjustment values, but have the same path loss compensation coefficient. Optionally, to avoid excessive power differences that could prevent dynamic signaling from being tracked, the access network equipment uses a semi-static configuration method to configure the power difference. For example, the access network equipment sends the power difference to the terminal at predetermined time intervals, and the terminal stores and uses the currently received power difference before the access network equipment sends it again.

[0129] It should be noted that there is no strict order between steps 401 and 403, that is, steps 401 and 403 can be executed simultaneously. This embodiment does not limit the execution order of the two.

[0130] Step 404: The terminal receives the power difference value sent by the access network device.

[0131] Optionally, the terminal calculates the expected transmission power of the access network device based on the power parameters configured in the access network device, and determines the transmission power of data in different areas based on the expected transmission power and the power difference.

[0132] Optionally, the terminal calculates the expected transmission power of the access network device based on the transmission power calculation formula agreed upon in the protocol and the power parameters configured in the access network device. This will not be elaborated further in this embodiment.

[0133] In one possible implementation, when the terminal is scheduled to transmit data in the first area, the terminal sets the transmission power (first power) to the expected transmission power minus the power difference.

[0134] When a terminal is scheduled to transmit data in the second area, the terminal sets its transmission power (second power) to the transmission power expected by the access network equipment.

[0135] When a terminal is scheduled to send high-priority data, it determines to send high-priority data in the first area and sets the transmission power to the expected transmission power of the access network equipment, thereby reducing interference from other low-priority data in the second area and improving the reliability of transmitting high-priority data.

[0136] In an illustrative example, in the scheduling scenario of eMBB and URLLC services, the expected transmission power of the access network device is P, and the power difference configured by the access network device is deltaP. When the terminal is scheduled to send eMBB data in the first area, the transmission power is set to P-deltaP; when the terminal is scheduled to send eMBB data in the second area, the transmission power is set to P; when the terminal is scheduled to send URLLC data in the first area, the transmission power is set to P.

[0137] Step 405: The terminal transmits data in the first area using the first power.

[0138] Based on the example in the above steps, when the terminal is scheduled to send eMMB data in the first area, it uses the transmit power P-deltaP to send the eMMB data.

[0139] Step 406: The terminal transmits data using the second power in the second area.

[0140] Referring to the example in the steps above, when the terminal is scheduled to send eMMB data in the second area, it uses the transmission power P to send the eMMB data.

[0141] Optionally, when there is a URLLC service preempting resources, the terminal uses a third power to send URLLC data in the first area. For example, the third power can be P in the example above.

[0142] In summary, in this embodiment, by configuring different regions on the transmission resources, the terminal can use corresponding power to send data in different regions, thereby avoiding the terminal frequently detecting control signals during uplink data transmission, thus reducing the terminal's power consumption. Furthermore, using different power for data transmission helps improve the reliability and efficiency of data transmission between the terminal and the access network equipment in the communication system.

[0143] In this embodiment, the access network device sends area configuration information and power differences between different areas to the terminal, so that the terminal can determine different areas based on the area configuration information and determine the transmission power of data in different areas based on the power differences, thereby performing subsequent uplink data transmission and improving the reliability and efficiency of uplink data transmission. At the same time, the access network device uses a semi-static method to configure the power differences, thereby avoiding the inability to track power jumps.

[0144] In this embodiment, access network devices exchange regional configuration information and make regional adjustments based on the obtained regional configuration information, thereby reducing interference between adjacent cells and further improving the data transmission quality of the system.

[0145] Please refer to Figure 5 This illustrates a flowchart of a data transmission method provided in another exemplary embodiment of this application. This embodiment applies the method to... Figure 1 The method is illustrated using the aforementioned communication system as an example. The method includes:

[0146] Step 501: The access network device sends area configuration information to the terminal. The area configuration information is used to indicate the configuration of the first area and the second area.

[0147] In this embodiment, the access network device configures two BWPs for the terminal, corresponding to the first area and the second area respectively. When sending area configuration information to the terminal, the access network device sends the configuration information of the two BWPs and the configuration information to the terminal.

[0148] Optionally, the two BWPs may correspond to different time-frequency domain resources. For example, BWP1 may correspond to PRB1-50, while BWP2 may correspond to PRB51-55. Alternatively, the two BWPs may correspond to the same time-frequency domain resources, but with different subcarrier spacings. For example, both BWP1 and BWP2 may correspond to PRB51-55, but BWP1 may have a subcarrier spacing of 60kHz, while BWP2 may have a subcarrier spacing of 15kHz. This embodiment does not limit this.

[0149] Step 502: The terminal receives the area configuration information sent by the access network device.

[0150] Accordingly, after receiving the area configuration information, the terminal determines the first area and the second area based on the BWP configuration information therein.

[0151] Step 503: The access network device sends power parameters to the terminal, wherein the power parameters of the first power are partially or entirely independently configured with respect to the power parameters of the second power.

[0152] In this embodiment, the access network device independently configures some or all (uplink) power parameters for each BWP, so that the terminal can determine the data transmission power in each area based on the power parameters configured for the BWP.

[0153] Optionally, the power parameter includes at least one of the following: target received power parameter, path loss compensation coefficient, and dynamic power adjustment value. The target received power parameter is the power of the data that the access network device expects to receive. The path loss compensation coefficient is used to compensate for power loss during transmission. The dynamic power adjustment value can be indicated by a value or a set (e.g., {-3,0,3,6}).

[0154] Optionally, the power parameters can be configured in the following ways.

[0155] 1. The target received power parameter and the path loss compensation coefficient in the power parameters are configured independently, while the dynamic power adjustment value in the power parameters is configured in a shared manner.

[0156] When this configuration method is adopted, the access network equipment configures the target received power parameters and path loss compensation coefficients for each BWP, and the dynamic power adjustment value is shared by each BWP. That is, different BWPs have different target received power parameters and different path loss compensation coefficients, but have the same dynamic power adjustment value.

[0157] For example, the power parameters transmitted by the access network equipment include the target received power P1 and path loss compensation coefficient a1 configured for BWP1, the target received power P2 and path loss compensation coefficient a2 configured for BWP2, and a uniformly configured dynamic power adjustment value f1.

[0158] This configuration method allows for differentiated power control based on different scenarios, services, and data types. Furthermore, it enables real-time tracking of channel changes based on shared dynamic power adjustment values.

[0159] 2. The target received power parameter, path loss compensation coefficient, and dynamic power adjustment value in the power parameters are configured independently.

[0160] When using this configuration method, the access network equipment configures each BWP with its own target received power parameters, path loss compensation coefficient, and dynamic power adjustment value. That is, different BWPs have different target received power parameters, different path loss compensation coefficients, and different dynamic power adjustment values.

[0161] For example, the power parameters transmitted by the access network equipment include the target received power P1, path loss compensation coefficient a1, and dynamic power adjustment value f1 configured for BWP1, and the target received power P2, path loss compensation coefficient a2, and dynamic power adjustment value f2 configured for BWP2.

[0162] By adopting this configuration method, since each BWP has its own power parameters, more precise power control can be performed for different scenarios, services and data types (but the signaling overhead also increases accordingly).

[0163] 3. The target received power parameter in the power parameters is configured independently, while the path loss compensation coefficient and dynamic power adjustment value in the power parameters are configured together.

[0164] When using this configuration method, the access network equipment configures the target received power parameters for each BWP, and configures a unified dynamic power adjustment value and path loss compensation coefficient for each BWP. That is, different BWPs have different target received power parameters, but have the same dynamic power adjustment value and different path loss compensation coefficients.

[0165] For example, the power parameters transmitted by the access network equipment include the target received power P1 configured for BWP1, the target received power P2 configured for BWP2, and the uniformly configured dynamic power adjustment value f1 and path loss compensation coefficient a1.

[0166] This configuration method allows for independent configuration of the target received power, enabling immediate power control tailored to different scenarios, services, and data types, while reducing the signaling overhead of configuring power parameters.

[0167] 4. The target received power parameter and dynamic power adjustment value in the power parameters are configured independently, while the path loss compensation coefficient in the power parameters is configured in a shared manner.

[0168] When using this configuration method, the access network equipment configures the target received power parameters and dynamic power adjustment values ​​for each BWP, and configures a uniform path loss compensation coefficient for each BWP. That is, different BWPs have different target received power parameters and different dynamic power adjustment values, but have the same path loss compensation coefficient.

[0169] For example, the power parameters transmitted by the access network equipment include the target received power P1 and dynamic power adjustment value f1 configured for BWP1, the target received power P2 and dynamic power adjustment value f2 configured for BWP2, and a uniformly configured path loss compensation coefficient a1.

[0170] 5. The path loss compensation coefficient in the power parameters is configured independently, while the target received power parameter and dynamic power adjustment value in the power parameters are configured together.

[0171] When using this configuration method, the access network equipment configures its own path loss compensation coefficient for each BWP, and configures a unified target received power parameter and dynamic power adjustment value for each BWP. That is, different BWPs have different path loss compensation coefficients, but have the same target received power parameter and dynamic power adjustment value.

[0172] 6. The path loss compensation coefficient and dynamic power adjustment value in the power parameters are configured independently, while the target received power parameter in the power parameters is configured in a shared manner.

[0173] When using this configuration method, the access network equipment configures its own path loss compensation coefficient and dynamic power adjustment value for each BWP, and configures a unified target received power parameter for each BWP. That is, different BWPs have different path loss compensation coefficients and dynamic power adjustment values, but have the same target received power parameter.

[0174] 7. The dynamic power adjustment value in the power parameters is configured independently, while the target received power parameter and the path loss compensation coefficient in the power parameters are configured together.

[0175] When this configuration method is adopted, the access network equipment configures its own dynamic power adjustment value for each BWP, and configures a unified target received power parameter and path loss compensation coefficient for each BWP. That is, different BWPs have different dynamic power adjustment values, but have the same target received power parameter and path loss compensation coefficient.

[0176] When configuring power parameters using the three methods described above, power control can be differentiated for different scenarios, services, and data types, and the signaling overhead when configuring power parameters can be reduced (due to the existence of shared configuration).

[0177] 8. The dynamic power adjustment value in the power parameters, the target received power parameters, and the path loss compensation coefficient are shared in the configuration.

[0178] When this configuration method is adopted, the access network equipment configures the same target received power parameters, path loss compensation coefficient and dynamic power adjustment value for each BWP, that is, different BWPs have the same target received power parameters, path loss compensation coefficient and dynamic power adjustment value.

[0179] When configuring power parameters in this way, the signaling overhead is minimized because different BWPs share the configuration parameters. Subsequently, the terminal performs differentiated power control based on the power differences configured by the access network equipment for different scenarios, services, and data types.

[0180] Step 504: The terminal receives the power parameters configured by the access network device.

[0181] The terminal receives and stores the power parameters configured by the access network device so that it can determine the transmission power based on these power parameters when sending uplink data later.

[0182] Step 505: The terminal determines the first power based on the power parameters and transmits data in the first area using the first power.

[0183] Optionally, the access network device configures the smaller target receive power in the power parameters for BWP1 (corresponding to the first area) so that when the terminal is scheduled to send data in the first area, the transmission power (i.e., the first power) is set based on the smaller target receive power in the power parameters, and the data is sent according to the set transmission power.

[0184] For example, when transmitting (uplink) eMMB data on BWP1, the terminal sets the transmission power with reference to the smaller target receiving power, thereby enabling the transmission of eMMB data at low power in the first area.

[0185] Step 506: The terminal determines the second power based on the power parameters and transmits data using the second power in the second area.

[0186] Optionally, the access network device configures the larger target receive power in the power parameters for BWP2 (corresponding to the second area) so that when the terminal is scheduled to send data in the second area, the transmission power (i.e., the second power) is set based on the larger target receive power in the power parameters, and the data is sent according to the set transmission power.

[0187] For example, when transmitting (uplink) eMMB data on BWP2, the terminal sets the transmission power with reference to the larger target receiving power, thereby enabling the transmission of eMMB data at high power in the second area.

[0188] Optionally, when URLLC data needs to be sent, the terminal can use the resources of BWP1 (corresponding to the first area) to send URLLC data by preempting resources and configuring it with a larger transmission power (e.g., based on a larger target reception power) to improve the reliability of URLLC data transmission.

[0189] In summary, in this embodiment, by configuring different regions on the transmission resources, the terminal can use corresponding power to send data in different regions, thereby avoiding the terminal frequently detecting control signals during uplink data transmission, thus reducing the terminal's power consumption. Furthermore, using different power for data transmission helps improve the reliability and efficiency of data transmission between the terminal and the access network equipment in the communication system.

[0190] Furthermore, in 5G systems, due to the different reliability requirements of URLLC and eMBB services, and the fact that the physical layer cannot see the service type, power control based on service type has become an unresolved issue. In this embodiment, by configuring at least two BWPs and transmitting URLLC data at high power only on one of the BWPs, power differentiation control based on service type is achieved, which is beneficial for improving the reliability of URLLC data transmission. Simultaneously, power enhancement only for URLLC data can reduce transmission power consumption and system interference.
