Problems solved by technology

[0004] However, in the dual connectivity transmission of NR and LTE systems, since NR and LTE belong to different systems, power coordination between LTE and NR cannot be performed through a power control scheme similar to that in LTE dual connectivity transmission. There is no control scheme for the uplink power of terminals in NR system and LTE system

Embodiment 1

[0096] The embodiment of the present invention provides an uplink power control method, which can be applied to figure 1 The network architecture shown. Such as figure 2 As shown, the method can include the following steps:

[0097] S11: The base station transmits power configuration information to the terminal, and the power configuration information is used to configure the terminal in the NR system and the maximum transmit power in the LTE system.

[0098] In the embodiment of the present invention, the base station may be a primary base station in two base stations that perform dual connectivity to the terminal. The base station can transmit power configuration information to the terminal by semi-static configuration to notify the terminal in the NR system and the upstream maximum transmit power in the LTE system.

[0099] In practical applications, the power configuration information sent by the base station can be used but not limited to the following manner:

Embodiment 2

[0149] Such as image 3 As shown, the embodiment of the present invention provides an uplink power control method with a two-connection with a wireless communication system NR and a long-term evolution system LTE. The network architecture in which the terminal is located. figure 1 . This method can be described as follows:

[0150] S51: The terminal receives the semi-static power configuration information transmitted by the base station, and configures the upstream maximum transmit power in the NR system and the LTE system based on the power configuration information;

[0151] S52: The terminal transmits the report information to the base station; wherein the reporting information is used to characterize the use of uplink transmit power in the NR system and the LTE system;

[0152] S53: The terminal receives the base station based on the instruction information feedback of the report information, and adjusts the information to the downlink control information DCI or high layer sign...

Embodiment 3

[0170] Such as Figure 4 As shown, the embodiment of the present invention provides an uplink power control method, and is applied to the base station, and the base station is a second base station in the terminal and the second base station in the long-term evolution system LTE in the wireless communication system NR. The first base station and the primary base station in the second base station, for example, the base station can be figure 1 The primary base station. This method can be described below.

[0171] S30: The base station sends semi-static power configuration information to the terminal, and the power configuration information is used to configure the terminal in the NR system and the minimum to ensure the proportional factor of the shared power margin in the LTE system.

[0172] Among them, the minimum ensures that the transmit power can be to ensure that the terminal can communicate with each system in a dual connection, the minimum transmit power on each system. For ...

Description

Technical field [0001] The present invention relates to the field of communication technology, and more particularly to an uplink power control method, a base station, and a terminal. Background technique [0002] With the development of mobile communication business, international Telecommmunication Union, ITU and 3rd Generation Partnership Projects (3GPP), etc. have begun to study new wireless communication systems, such as the 5th generation. Wireless access system (5Generation New Rat, 5G NR). Therefore, in the future 5G network construction, wireless resource utilization can be improved through the 5G NR system and the long-term evolution (LTE) system, and the user and system performance are improved. [0003] Currently, in the Dual Connection Transmission of the LTE system, the terminal (UE) is connected to two different base stations, and the radio resources of the two base stations are also enjoyed. These two base stations may be defined as the primary base station (MeNB)...
