Problems solved by technology

[0004] However, in the prior art, according to the power-related parameters configured by the base station, only fixed power can be calculated, that is, the same power is used for each data transmission, and the start time of sending a data packet cannot be determined at present, so the power of a data packet cannot be guaranteed. The number of repeated transmissions, resulting in the reliability of data packet transmission cannot be guaranteed
In addition, multiple repeated transmissions use the same power, and the time sensitivity is not high
In addition, during the multiple repetitions of one data packet transmission, the channel conditions may not change much, and the situation of deep fading at the same time will cause the reliability of this transmission to be low.

Abstract

The invention provides an uplink transmission power adjusting method and device, and the method comprises the steps that a terminal receives configuration information sent by network equipment, the configuration information comprises the maximum repetition frequency k of repeated transmission and parameters used for determining the initial transmission power, and k is an integer greater than 0; and the actual sending power of the data packet is determined according to the maximum repetition frequency k of the repeated transmission, the initial sending power and the time domain position of theinitial transmission of the sending data packet. When the data packet is transmitted, the actual transmitting power of the data packet can be flexibly determined, so that the transmission reliabilityof the data packet is better ensured.

Description

Technical field [0001] This application relates to wireless communication technology, and in particular to an uplink transmission power adjustment and device. Background technique [0002] The International Telecommunication Union (ITU) defines three types of application scenarios for fifth-generation (5G) communication systems and future mobile communication systems, including: enhanced mobile broadband (eMBB), high reliability and low time Extended communications (ultra reliable and low latency communications, URLLC) and massive machine type communications (mMTC). Typical URLLC business application scenarios include: wireless control, virtual reality technology, remote surgery and other tactile interactive applications in industrial manufacturing. The main characteristics of these services are that they require ultra-high reliability and low latency. In industrial manufacturing, once every movement of every piece of equipment has a deviation, it will affect the overall product...
