[0042] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0043] With the continuous development of wireless communication technologies, the research and development work of the fifth-generation mobile communication technology (5G) has been ongoing for many years. However, in actual applications, the 5G network is not yet fully mature, and the fourth-generation mobile communication technology (4G) is still widely used. In the case of coexistence of 4G and 5G networks, the ENDC (E-UTRA NR Dual-Connectivity) technology has emerged. Among them, E-UTRA (Evolved Universal Terrestrial Radio Access) is a radio access technology in the Long Term Evolution (LTE) system, and NR (New Radio) is a radio access technology in the 5G system.

[0044] The ENDC technology is mainly based on the LTE network and supplemented by the NR network. On the one hand, it can fully utilize the currently mature 4G network, saving network deployment costs. On the other hand, it can also reduce the technical difficulty, enabling major operators to smoothly transition to 5G as soon as possible.

[0045] As an example, the network architecture of ENDC can be as Figure 1 shown.

[0046] The uplink communication method, electronic device, and computer-readable storage medium of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0047] Figure 2 It is a schematic flowchart of an uplink communication method provided by an embodiment of the present application. It should be noted that the method is applied to a terminal.

[0048] As Figure 2 shown, the uplink communication method may include the following steps:

[0049] Step 201, determine the first power for transmitting the first signal and the second power for transmitting the second signal.

[0050] In the embodiments of the present application, the terminal can determine the first power corresponding to transmitting the first signal and the second power corresponding to transmitting the second signal.

[0051] Among them, the time-domain resources of the first signal and the second signal overlap in time.

[0052] Optionally, the first signal is an uplink signal corresponding to the Master Cell Group (MCG), and the second signal is an uplink signal corresponding to the Secondary Cell Group (SCG). Optionally, the MCG uses radio access of E-UTRA, and the SCG uses radio access of NR.

[0053] Optionally, the first signal is an uplink signal corresponding to the SCG, and the second signal is an uplink signal corresponding to the MCG. Optionally, the MCG uses radio access of NR, and the SCG uses radio access of E-UTRA.

[0054] Optionally, the second signal may include at least one of the following: Physical Random Access Channel (PRACH), Sounding Reference Signal (SRS), Physical Uplink Shared Channel (PUSCH), and Physical Uplink Control Channel (PUCCH).

[0055] Optionally, the first signal may include at least one of the following: Physical Random Access Channel PRACH, Sounding Reference Signal SRS, Physical Uplink Shared Channel PUSCH, and Physical Uplink Control Channel PUCCH.

[0056] As an example, the first signal is an uplink signal corresponding to a master cell group (MCG), and the second signal is an uplink signal corresponding to a secondary cell group (SCG). Among them, the master cell group MCG uses radio access of E-UTRA, and the secondary cell group uses radio access of NR. The terminal determines that the transmission power of the first signal is The transmission power of the second signal is Wherein, is the linear value of the total transmission power on subframe i of MCG 1 and is the linear value of the total transmission power on slot i of SCG 2 and

[0057] In the embodiments of the present application, the terminal capability supports dynamic power sharing.

[0058] Step 202: Determine that the sum of the first power and the second power is greater than the first threshold, and reduce the second power to the third power.

[0059] In the embodiments of the present application, the terminal can determine whether the sum of the first power and the second power exceeds the first threshold.

[0060] In some embodiments, the sum of the first power and the second power is greater than the first threshold, and the terminal reduces the second power to the third power, where the sum of the third power and the first power is less than or equal to the first threshold.

[0061] In some embodiments, the sum of the first power and the second power is less than or equal to the first threshold, and the terminal can transmit the first signal and the second signal with the first power and the second power respectively.

[0062] Optionally, the first threshold is a linear value of the maximum transmission power of the terminal.

[0063] Optionally, the first threshold may be configured by a network device or may be specified by a protocol.

[0064] As an example, the first signal is an uplink signal corresponding to a master cell group (MCG), and the second signal is an uplink signal corresponding to a secondary cell group (SCG). Among them, the MCG uses E-UTRA radio access, and the SCG uses NR radio access. The terminal determines that the transmission power of the first signal is The transmission power of the second signal is The first threshold is Among them, is a linear value of the total transmission power on subframe i of the MCG 1 and is a linear value of the total transmission power on time slot i of the SCG 2 and is a linear value of the maximum transmission power of the terminal. The terminal can determine Or,

[0065] In some embodiments, the difference between the third power and the second power is greater than a second threshold.

[0066] Optionally, the second threshold may be determined based on configuration information sent by a network device or may be determined based on protocol specifications.

[0067] That is, when the terminal reduces the transmission power corresponding to the second signal, it may reduce the power by more than the second threshold, such that the sum of the third power and the first power is less than or equal to the first threshold.

[0068] Step 203: Transmit the first signal based on the first power and transmit the second signal based on the third power.

[0069] Optionally, the first signal and the second signal are transmitted simultaneously.

[0070] Optionally, the time domain resources of the first signal and the second signal overlap in time.

[0071] In the embodiments of the present application, the terminal can transmit the first signal based on the first power and transmit the second signal based on the reduced third power.

[0072] In some embodiments, the difference between the third power and the second power is greater than a second threshold.

[0073] That is, even if the power is reduced by more than a second threshold such that the sum of the third power and the first power is less than or equal to the first threshold, the terminal can still continue to transmit the second signal based on the third power. Since the above-mentioned calculation and determination of power are performed on the terminal side, actually at the time point when the second signal (e.g., NR uplink signal) is transmitted, the network side does not know how much power the terminal will use to transmit the second signal at this time point, nor does the network side know whether the power reduced by the terminal at this time point will exceed the second threshold. Therefore, the network device will still continue to receive and process the second signal according to the air interface configuration at this time point. In this case, if the terminal continues to transmit the second signal based on the third power, the network device still has a probability of correctly receiving the signal and demodulating it.

After reducing the transmission power of the signal, the terminal can continue to transmit the uplink signal without actively discarding the transmission of any uplink signal, which can effectively increase the probability of the signal being correctly received, ensure normal communication between the terminal and the network, improve the communication efficiency of the system, and improve the resource utilization rate.

[0084] Figure 3 It is a schematic flowchart of another uplink communication method provided by the embodiment of the present application. It should be noted that the method is applied to a terminal device.

[0085] As Figure 3 shown, the uplink communication method may include the following steps:

[0086] Step 301, determine the first power for transmitting the first signal and the second power for transmitting the second signal.

[0087] In the embodiment of the present application, the terminal can determine the first power corresponding to transmitting the first signal and the second power corresponding to transmitting the second signal.

[0088] Wherein, the time domain resources of the first signal and the second signal overlap in time.

[0089] Optionally, the first signal is an uplink signal corresponding to a master cell group (MCG), and the second signal is an uplink signal corresponding to a secondary cell group (SCG). Optionally, the master cell group MCG uses E-UTRA radio access, and the secondary cell group uses NR radio access.

[0090] Optionally, the first signal is an uplink signal corresponding to a secondary cell group (SCG), and the second signal is an uplink signal corresponding to a master cell group (MCG). Optionally, the master cell group MCG uses NR radio access, and the secondary cell group uses E-UTRA radio access.

[0091] Optionally, the second signal may include at least one of the following: Physical Random Access Channel (PRACH), Channel Sounding Reference Signal (SRS), Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH).

[0092] Optionally, the first signal may include at least one of the following: Physical Random Access Channel (PRACH), Channel Sounding Reference Signal (SRS), Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH).

[0093] As an example, the first signal is an uplink signal corresponding to the master cell group (MCG), and the second signal is an uplink signal corresponding to the secondary cell group (SCG). Among them, the MCG uses the radio access of E-UTRA, and the SCG uses the radio access of NR. The terminal determines that the transmission power of the first signal is The transmission power of the second signal is Among them, is the linear value of the total transmission power on subframe i of the MCG 1 and is the linear value of the total transmission power on slot i of the SCG 2 and

[0094] In the embodiment of the present application, the terminal capabilities support dynamic power sharing.

[0095] Step 302, determine whether the sum of the first power and the second power is greater than a first threshold.

[0096] In the embodiment of the present application, the terminal can determine whether the sum of the first power and the second power exceeds the first threshold.

[0097] Optionally, the first threshold is the linear value of the maximum transmission power of the terminal.

[0098] Optionally, the first threshold can be configured by the network device or can also be specified by the protocol.

[0099] As an example, the first signal is an uplink signal corresponding to the master cell group (MCG), and the second signal is an uplink signal corresponding to the secondary cell group (SCG). Among them, the MCG uses the radio access of E-UTRA, and the SCG uses the radio access of NR. The terminal determines that the transmission power of the first signal is The transmission power of the second signal is The first threshold is Among them, is the linear value of the total transmission power on subframe i of the MCG 1 and is the linear value of the total transmission power on slot i of the SCG 2 and is the linear value of the maximum transmission power of the terminal. The terminal can determine Or

[0100] In some embodiments, when the sum of the first power and the second power is greater than the first threshold, steps 303-304 are executed.

[0101] In some embodiments, if the sum of the first power and the second power is less than or equal to the first threshold, step 305 is executed.

[0102] In step 303, it is determined that the sum of the first power and the second power is greater than the first threshold, and the second power is reduced to a third power.

[0103] In some embodiments, the terminal determines that the sum of the first power and the second power is greater than the first threshold, and the terminal reduces the second power to a third power, where the sum of the third power and the first power is less than or equal to the first threshold.

[0104] In some embodiments, the difference between the third power and the second power is greater than a second threshold.

[0105] Optionally, the second threshold may be determined based on the configuration information sent by the network device or based on the provisions of the protocol.

[0106] That is, when the terminal reduces the transmission power corresponding to the second signal, it may reduce the power by more than the second threshold, so that the sum of the third power and the first power is less than or equal to the first threshold.

[0107] In step 304, the first signal is sent based on the first power, and the second signal is sent based on the third power.

[0108] Optionally, the first signal and the second signal are sent simultaneously.

[0109] Optionally, the time-domain resources of the first signal and the second signal overlap in time.

[0110] In the embodiments of the present application, the terminal can send the first signal based on the first power and send the second signal based on the reduced third power.

[0111] In some embodiments, the difference between the third power and the second power is greater than a second threshold.

[0112] That is, even if the power is reduced by more than the second threshold to make the sum of the third power and the first power less than or equal to the first threshold, the terminal can still continue to send the second signal based on the third power. Since the above-mentioned power calculation and judgment are performed on the terminal side, actually at the time point when the second signal (for example, NR uplink signal) is sent, the network side does not know how much power the terminal will use to send the second signal at this time point, nor does the network side know whether the power reduced by the terminal at this time point will exceed the second threshold. Therefore, the network device will still continue to receive and process the second signal according to the air interface configuration at this time point; in this case, if the terminal continues to send the second signal based on the third power, the network device still has a probability of correctly receiving the signal and demodulating it.

[0113] Step 305: Determine that the sum of the first power and the second power is less than or equal to the first threshold, send the first signal based on the first power, and send the second signal based on the second power.

[0114] In some embodiments, the terminal determines that the sum of the first power and the second power is less than or equal to the first threshold, and the terminal can send the first signal based on the first power and send the second signal based on the second power.

[0115] Optionally, the first signal and the second signal are sent simultaneously.

[0116] Optionally, the time-domain resources of the first signal and the second signal overlap in time.

[0117] In the uplink communication method according to the embodiments of the present application, by determining the first power for sending the first signal and the second power for sending the second signal, it is determined whether the sum of the first power and the second power is greater than the first threshold. If it is determined that the sum of the first power and the second power is greater than the first threshold, the second power is reduced to the third power, the first signal is sent based on the first power, and the second signal is sent based on the third power. If it is determined that the sum of the first power and the second power is less than or equal to the first threshold, the first signal is sent based on the first power, and the second signal is sent based on the second power. Wherein, the first signal and the second signal are sent simultaneously. After the terminal reduces the transmission power of the signal, it can continue to send the uplink signal without actively discarding the transmission of any uplink signal, which can effectively increase the probability that the signal is correctly received, ensure normal communication between the terminal and the network, improve the communication efficiency of the system, and improve the resource utilization rate.
