Signal sending method and device

Abstract

The invention provides a signal sending method and device. The method comprises the following steps: determining a first sending power for a first signal in a first time unit on a first carrier, and determining a second sending power for a second signal in a second time unit on a second carrier; and when the second signal is a signal capable of occupying guaranteed power corresponding to other cell groups in a second cell group, determining the sending power of the first signal as third sending power, and sending the first signal at the third sending power in a first time unit on the first carrier, and transmitting a second signal at a second transmission power within a second time unit on a second carrier. According to the scheme, when the second signal is the signal capable of occupyingthe guaranteed power corresponding to the other cell groups in the second cell group, the sending of the second signal is preferentially guaranteed, the sending of the signal capable of occupying theguaranteed power corresponding to the other cell groups can be preferentially guaranteed, and the system performance can be further improved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a signal sending method and device. Background technique [0002] In the Long term evolution (LTE) system, a terminal device supports simultaneous access to two network devices. This access method is called dual connectivity (Dual Connectivity, DC). One of the network devices is the main network device. Another network device is a secondary network device, wherein one or more cells that are served by the main network device for the terminal device are called Master Cell Groups (Master Cell Group, MCG), and one or more cells that the secondary network device provides services for the terminal device One or more cells are called secondary cell group (Secondary Cell Group, SCG). During the development and evolution of the wireless communication system, operators will deploy both the 5th generation (5G) New radio interface (NR) system and the Long term evo...

Problems solved by technology

[0005] In order to increase the rate at which terminal devices send uplink signals to network devices, usually terminal devices working in dual connectivity mode can simultaneously send uplink signals to network devices on at least two carriers within the same period of time, but the terminal The total power of sending uplink signals is often limited, for example, the maximum cannot exceed 23dBm. Therefore, if the total power of the terminal device sending uplink signals on at least two carriers exceeds the maximum transmission power, the terminal device needs to actively reduce one or more carriers. transmit power on

[0006] At present, the method for terminal equipment to adjust the transmission power is not suitable for some scenarios, which will lead to system performance degradation
