example 1

[0069] For an example, see figure 2 , assuming that the receiving time of the uplink grant (UL grant) corresponding to the uplink transmission not actually started in the MCG is t1, the receiving time of the UL grant corresponding to the uplink transmission not actually started in the SCG is t2, and t1<t2; The offset is t_offset; the start time of UE1's uplink transmission in MCG is t3, and the start time of UE1's uplink transmission in SCG is t4, and t3<t4; according to the transmission priority of different channels agreed in the agreement, MCG and SCG The transmission priority of the uplink channel is the same; then:

[0070] The start time of the preset time window is: t1 (that is, the earliest receiving time in the uplink grant corresponding to the uplink transmission not actually started in the MCG and SCG).

[0071] The end time of the preset time window is: t3-t_offset; the t3 is the earliest start time of UE1's uplink transmission in MCG and SCG.

Abstract

The invention provides an uplink transmission power distribution method and a terminal. The method comprises the steps: carrying out the power distribution of the uplink transmission of the terminal at MCG and SCG in a preset time window under the condition that the sum of first power and second power is greater than third power, wherein the first power is the transmitting power of the terminal in the MCG, the second power is the transmitting power of the terminal in the SCG, the third power is the configured maximum total transmitting power of the terminal, and the maximum total transmitting power is the sum of the transmitting power of the terminal in the MCG and the transmitting power of the terminal in the SCG. According to the scheme provided by the invention, reasonable power distribution between the MCG and the SCG can be realized, the uplink coverage performance is enhanced, the uplink transmission phase discontinuity is avoided, and the uplink transmission reliability is ensured.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for allocating uplink transmission power and a terminal. Background technique [0002] Under New Radio, New Radio, Dual-connectivity, NN-DC, when the Master Cell Group (MCG) and the Secondary Cell Group (SCG) are on the same frequency When within the range, if dynamic power sharing is supported among cell groups (Cell Groups, CGs), how to perform power allocation among CGs has not yet been determined. In this way, if the power control is performed independently between the MCG and the SCG, each CG can only allocate part of the power due to the maximum transmit power limit of the terminal, which will result in limited uplink coverage; and if the MCG or SCG is prioritized for transmission, since it is necessary to ensure that a CG Power, the power of another CG may be adjusted, which will cause discontinuity in the uplink transmission phase and affect the...
