Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus and system for configuring uplink transmit and receive power. Background Technology

[0002] The New Radio (NR) system employs a multi-point collaboration approach to improve coverage at the cell edge and provide a more balanced quality of service within the service area.

[0003] With the increasing use of millimeter-wave bands, which generally refer to electromagnetic waves with wavelengths of 1-10 millimeters, the blocking effect caused by their extremely short wavelengths is more pronounced against various obstacles. In this context, to ensure the robustness of link connections, cooperation between multiple transmission-reception points (TRPs) or antenna panels can be utilized to transmit from multiple angles using multiple beams, thereby reducing the adverse effects of blocking. In some implementations, for both uplink and downlink data, the user equipment can only transmit or receive one beam on the same antenna panel. In other implementations, downlink enhancement allows the user equipment to simultaneously receive multiple beams from different TRPs in different directions on multiple antenna panels. In some possible implementations, it is desirable for the user equipment to simultaneously transmit different beams on multiple antenna panels in the uplink direction.

[0004] Since different TRPs may have different path losses, it is necessary to consider how to perform uplink power control for different TRPs. Summary of the Invention

[0065] like Figure 1 As shown in the embodiments of this disclosure, a method for configuring uplink transmit and receive power can be applied to a wireless communication system 100, which may include a user equipment 102 and a network device 101. The user equipment 102 is configured to support carrier aggregation and can be connected to multiple carrier units of the network device 101, including a primary carrier unit and one or more secondary carrier units.

[0066] It should be understood that the wireless communication system 100 described above is applicable to both low-frequency and high-frequency scenarios. Application scenarios for the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future 5th-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems.

[0083] In some possible implementations, the user equipment determines the maximum uplink transmit power of each of the N antenna panels according to a protocol.

[0084] In this embodiment of the disclosure, the network device configures uplink transmit power configuration information for each antenna panel of the user equipment, and the user equipment performs uplink transmit power control on each antenna panel separately. That is, configuration and power control are performed at the antenna panel level. Based on the different transmit capabilities of different antenna panels, uplink transmit power corresponding to the transmit capability is allocated to antenna panels with different transmit capabilities, so that the uplink transmit power on each antenna panel is adapted to the transmit capability, making full use of the transmit capability of each antenna panel, avoiding the situation of transmission failure due to low transmit power and the problem of adjacent channel interference and energy waste due to high transmit power.

[0088] Step S302: The user equipment controls the uplink transmit power of different antenna panels in the user equipment according to the uplink transmit power configuration information.

[0089] In some possible implementations, the sum of the uplink transmit power of the M antenna panels in the user equipment is less than or equal to a preset threshold, where M is a positive integer and less than or equal to N, and N is the total number of antenna panels in the user equipment.

[0090] In some possible implementations, the uplink transmit power of M antenna panels is controlled according to the priority of the signals transmitted by different antenna panels, where M is a positive integer and less than or equal to N, where N is the number of antenna panels included in the user equipment, and the sum of the uplink transmit power of the M antenna panels in the user equipment is greater than a preset threshold.

Figure 4 This is a flowchart illustrating a method for transmitting and receiving uplink transmit power configuration according to an exemplary embodiment, such as... Figure 4 As shown, the method includes steps S401 to S402, specifically:

[0093] Step S401: The network device sends uplink transmit power configuration information to the user equipment.
