[0031] In order to enable those of ordinary skill in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such used data may be interchanged under appropriate circumstances so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0033] Currently, in the existing protocol, it is stipulated that in the evolved UMTS terrestrial radio access network - new radio dual connectivity (ENDC) mode, when the uplink channel for new radio (NR) signal transmission and the uplink channel for long term evolution (LTE) signal transmission meet the power adjustment conditions, the power of the uplink channel for NR signal transmission is reduced.

[0034] In the above stipulation, when LTE signals are transmitted on the LTE uplink channel with full power and the LTE signal transmission is relatively frequent, it may cause the NR PRACH signals on the NR PRACH uplink channel to frequently be transmitted with a lower power, resulting in multiple transmission failures of the NR PRACH signals, and it is difficult for the terminal device to complete the random access process in the NR network.

[0035] Figure 1Flow chart of a signal transmission method according to an embodiment of the present disclosure. It should be noted that the signal transmission method of this embodiment can be applied to a signal transmission device, which can be configured in an electronic device or a chip, so that the electronic device or the chip can perform the signal transmission function.

[0036] Among them, the electronic device can be any device with computing power, such as a personal computer (PC), a mobile terminal, a terminal device, a server, an antenna device, a satellite scanning device, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, etc., which are hardware devices with various operating systems, touch screens, and / or display screens.

[0037] In addition, the signal transmission device can also be software in the electronic device, etc. Among them, the software is, for example, signal transmission software, etc. Among them, in the following embodiments, the execution entity is taken as an example of a terminal device for description.

[0038] As Figure 1 shown, the method includes the following steps:

[0039] Step 101, in the evolved UMTS terrestrial radio access network-new radio dual connectivity (ENDC) mode, obtain the new radio (NR) signal to be transmitted in the terminal device, and the first power of the first uplink channel for NR signal transmission.

[0040] In the embodiment of the present disclosure, in the evolved UMTS terrestrial radio access network-new radio dual connectivity (ENDC) mode, the terminal device is allowed to be simultaneously connected to the long-term evolution (LTE) network of the 4th generation mobile communication technology (4G) and the new radio (NR) network of the 5th generation mobile communication technology (5G). Among them, in the ENDC mode, the LTE network device serves as the main network device (master node), and the NR network device serves as the secondary network device (secondary node), which can assist in data transmission, thereby improving the performance and capacity of the overall network.

[0041] Step 102, when the NR signal is a new radio physical random access channel (NR PRACH) signal and the NR signal is not a first-time transmission, perform NR signal transmission processing on the first uplink channel according to the first power.

[0042] Among them, the NR signal is a non-primary transmission, which may refer to the second transmission, the third transmission, etc. of the NR signal, and no specific limitation is made here.

[0043] Among them, the primary transmission of the NR PRACH signal refers to the process in which the terminal device first sends the NR PRACH signal to the network device through the PRACH channel when attempting to establish a connection with the network device. The non-primary transmission of the NR PRACH signal may refer to the retransmission process of the NR PRACH signal after the connection establishment fails.

[0044] In the embodiments of the present disclosure, when the NR signal is a non-primary transmission, the reasons for the non-primary transmission of the NR signal may include at least one of the following: the last transmission of the NR signal fails, no response is received after the last transmission of the NR signal, etc. Among them, the last transmission of the NR signal may be a primary transmission or a non-primary transmission.

[0045] For example, when the current non-primary transmission of the NR signal is the second transmission, the last transmission of the NR signal may be a primary transmission. When the current non-primary transmission of the NR signal is the third transmission or more transmissions, the last transmission of the NR signal may be a non-primary transmission.

[0046] In the embodiments of the present disclosure, the New Radio Physical Random Access Channel (NR PRACH) signal is a signal sent by the terminal device to the network device during the random access process.

[0047] In the embodiments of the present disclosure, after step 102, the terminal device may further perform the following process: when the NR PRACH signal transmission fails, re-obtain the NR PRACH signal to be transmitted and the power of the uplink channel for NR PRACH signal transmission; perform the transmission processing of the NR PRACH signal on the uplink channel according to the power.

[0048] In an embodiment of the present disclosure, the first power includes full power.

[0049] In the embodiments of the present disclosure, when initially transmitting the NR PRACH signal, the power of the uplink channel for NR PRACH signal transmission includes full power.

[0050] In the signal transmission method according to an embodiment of the present disclosure, in an evolved UMTS terrestrial radio access network-new radio dual connectivity (ENDC) mode, a new radio (NR) signal to be transmitted in a terminal device and a first power of a first uplink channel for NR signal transmission are obtained; when the NR signal is a new radio physical random access channel (NR PRACH) signal and the NR signal is not a first-time transmission, the NR signal is transmitted and processed on the first uplink channel according to the first power; wherein, for the NR PRACH signal, when it is not an initial transmission, the NR signal is transmitted and processed on the first uplink channel according to the first power, which can improve the transmission success rate of the NR PRACH signal, and further ensure the random access success rate and random access efficiency of the terminal device in the ENDC mode.

[0051] Figure 2 The flowchart of the signal transmission method according to another embodiment of the present disclosure is shown. It should be noted that the signal transmission method of this embodiment can be applied to a signal transmission device, which can be configured in an electronic device or a chip, so that the electronic device or the chip can perform the signal transmission function.

[0052] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a terminal device, a server, an antenna device, a satellite scanning device, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, etc., which are hardware devices with various operating systems, touch screens, and / or display screens.

[0053] In addition, the signal transmission device can also be software in an electronic device, etc. Among them, the software is, for example, signal transmission software, etc. In the following embodiments, the execution entity is taken as an example of a terminal device for description.

[0054] As Figure 2 shown, the method includes the following steps:

[0055] Step 201, in an evolved UMTS terrestrial radio access network-new radio dual connectivity (ENDC) mode, obtain a new radio (NR) signal to be transmitted in a terminal device and a first power of a first uplink channel for NR signal transmission.

[0056] Step 202, when the NR signal is a new radio physical random access channel (NR PRACH) signal and the NR signal is not a first-time transmission, perform transmission processing of the NR signal on the first uplink channel according to the first power.

[0057] Step 203: When the NR signal is not an NR PRACH signal, or when the NR signal is an NR PRACH signal and is a primary transmission, obtain the second power of the second uplink channel for Long Term Evolution (LTE) signal transmission in the ENDC mode.

[0058] In the embodiments of the present disclosure, when the NR signal is not an NR PRACH signal, regardless of whether the NR signal is a primary transmission, steps 203 and 204 can be directly executed to perform transmission control processing on the NR signal.

[0059] Among them, when the NR signal is an NR PRACH signal and is a primary transmission, steps 203 and 204 can be executed. When the NR signal is an NR PRACH signal and is not a primary transmission, the NR signal can be directly transmitted on the first uplink channel according to the first power to improve the transmission success rate of the NR signal.

[0060] In the embodiments of the present disclosure, it is also possible to determine whether to execute the steps in combination with whether the terminal device supports ENDC power sharing to reduce the power consumption of the terminal device. Correspondingly, the terminal device can determine whether it supports ENDC power sharing; if it supports ENDC power sharing, steps 203 and 204 are executed; if it does not support ENDC power sharing, the NR signal is directly transmitted on the first uplink channel according to the first power.

[0061] In the embodiments of the present disclosure, ENDC power sharing means that the terminal device can dynamically share the transmit power between the LTE network and the NR network. That is to say, the terminal device is allowed to flexibly adjust the power allocation between the two networks according to the current communication requirements and the conditions of the two networks.

[0062] Step 204: Perform transmission control processing on the NR signal according to the first uplink channel, the second uplink channel, the first power, and the second power.

[0063] In the embodiments of the present disclosure, the process of the terminal device executing step 204 can be, for example, to determine whether the first uplink channel meets the power adjustment condition according to the first uplink channel, the second uplink channel, the first power, and the second power; when the first uplink channel meets the power adjustment condition, adjust the first power until the first uplink channel does not meet the power adjustment condition to obtain the adjusted first power; and transmit the NR signal on the first uplink channel according to the adjusted first power.

[0064] Among them, the process by which the terminal device determines whether the first uplink channel meets the power adjustment condition may, for example, include the following steps: obtain the power sum of the first power and the second power; when there is a time-domain overlap between the first uplink channel and the second uplink channel and the power sum is greater than the power threshold in the ENDC mode, determine that the first uplink channel meets the power adjustment condition; when there is no time-domain overlap between the first uplink channel and the second uplink channel, or when the power sum is less than or equal to the power threshold, determine that the first uplink channel does not meet the power adjustment condition.

[0065] Among them, the existence of a time-domain overlap between the first uplink channel and the second uplink channel may mean that the transmission time of the LTE signal overlaps with the transmission time of the NR signal.

[0066] Among them, performing an adjustment process on the first power can ensure that the power sum of the first power and the second power is less than or equal to the power threshold, thereby avoiding excessive power consumption of the terminal device and ensuring the performance of the terminal device.

[0067] Among them, it should be noted that for the detailed description of steps 201 to 202, reference can be made to Figure 1 Steps 101 to 102 in the illustrated embodiment, and no detailed description will be given here.

[0068] In the signal transmission method of the embodiments of the present disclosure, in the evolved UMTS terrestrial radio access network - new radio dual connectivity ENDC mode, obtain the new radio NR signal to be transmitted in the terminal device and the first power of the first uplink channel for NR signal transmission; when the NR signal is a new radio physical random access channel NR PRACH signal and the NR signal is not a first transmission, perform NR signal transmission processing on the first uplink channel according to the first power; when the NR signal is not an NR PRACH signal, or when the NR signal is an NR PRACH signal and the NR signal is a first transmission, obtain the second power of the second uplink channel for long term evolution technology LTE signal transmission in the ENDC mode; perform transmission control processing on the NR signal according to the first uplink channel, the second uplink channel, the first power, and the second power; among them, when the NR signal is not an NR PRACH signal, or when the NR signal is an NR PRACH signal and the NR signal is a first transmission, combining the first uplink channel and the second uplink channel to perform transmission control processing on the NR signal can ensure that the power sum of the first power and the second power is less than or equal to the power threshold, thereby avoiding excessive power consumption of the terminal device and ensuring the performance of the terminal device.

[0069] The following is an example for illustration. As Figure 3 shown, it is a schematic diagram of signal transmission. Among them, the following steps may be included.

[0070] Step 301, start.

[0071] In step 302, the transmission power of the LTE uplink channel is full power in the ENDC scenario, while the NR PRACH uplink channel needs to send a signal.

[0072] In step 303, check whether the transmission times of the NR PRACH uplink channel and the LTE uplink channel overlap; if they overlap, execute step 304; if not, execute step 306.

[0073] In step 304, check whether it is the first transmission of the NR PRACH signal; if so, execute step 305; if not, execute step 306.

[0074] In step 305, reduce the transmission power of the NR PRACH uplink channel; keep the power of the LTE uplink channel unchanged; then execute step 307.

[0075] In step 306, keep the transmission power of the NR PRACH uplink channel unchanged; keep the power of the LTE uplink channel unchanged; then execute step 307.

[0076] Step 307, end.
