Abstract

The invention discloses a method for determining uplink channel transmission power. The method comprises the following steps: determining a corresponding reference uplink channel for each target uplink channel, wherein the sending time of the reference uplink channel is earlier than the sending time of the target uplink channel, and the control information receiving time of the reference uplink channel is earlier than the control information receiving time of the target uplink channel; accumulating the power adjustment amount in the control information between a calculation starting moment anda calculation stopping moment to obtain a total adjustment value for adjusting the target uplink channel power, wherein the starting moment is the control information receiving time of the referenceuplink channel, and the cut-off moment is between the control information receiving time of the target uplink channel and the sending time of the target uplink channel. The invention further providesa device for determining the uplink channel transmission power. According to the scheme of the invention, the problem of how to determine the total adjustment value of the transmission power of an uplink channel when the sending time sequence of the downlink control information is different from a sending time sequence of a scheduled uplink channel is solved.

Description

technical field [0001] The present application relates to the field of mobile communications, in particular to a method and device for determining uplink channel transmission power. Background technique [0002] The New Radio (NR) wireless communication system supports three types of communication services: Mobile Enhanced Bandwidth (eMBB), Highly Reliable Low Latency Communication (URLLC) and Massive Internet of Things (mMTC). Rel.15 is mainly used in eMBB scenarios. The URLLC service that needs to be supported in the Rel.16 research system requires a reliability of 1×10 -6 , and the delay is kept between 0.5-1ms. The uplink power control in the wireless system can ensure the quality of the uplink data sent by the UE in the cell, reduce the interference to other users in the system as much as possible, and prolong the battery life of the UE. [0003] In the prior art, the transmission power of the Physical Uplink Shared Channel (PUSCH) is accumulated and calculated accord...
