Problems solved by technology

Different subcarrier spacing destroys the orthogonality between subcarriers, which in turn causes interference between subcarriers in the system
At the same time, since the subcarrier spacing adopted by the new air interface technology may be different from the subcarrier spacing of LTE (Long Term Evolution, long-term evolution), the new air interface and LTE may experience stronger interference than between LTE and LTE

Abstract

The invention discloses a method and device for adjusting transmitting power in UE (User Equipment) and a base station. The method comprises the following steps: transmitting a first wireless signal by the UE on a first time-frequency resource, or receiving the first wireless signal on the first time-frequency resource, wherein the first time-frequency resource comprises a first sub time-frequencyresource and a second sub time-frequency resource; the first sub time-frequency resource is different from the second sub time-frequency resource, and the first sub time-frequency resource and the second sub time-frequency resource occupy the same time interval on a time domain; the normalized emission energy of each RU of the first wireless signal in the first sub time-frequency resource is first energy, and the normalized emission energy of each RU of the first wireless signal in the second sub time-frequency resource is second energy; and the first energy is not equal to the second energy.The method disclosed by the invention can reduce interferences among different mathematical structure areas inside a system and interferences among different systems, and improve the frequency spectrum utilization.

Description

technical field [0001] The present invention relates to a transmission scheme in a wireless communication system, in particular to a method and a device for adjusting transmission power. Background technique [0002] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the new air interface technology (NR, New Radio) for research. [0003] In order to be able to flexibly adapt to a variety of different application scenarios, future wireless communication systems, especially NR, will be able to support multiple numerology structures. CP (Cyclic Prefix, cyclic prefix) length, etc. Different subcarrier spacing destroys the orthogonality between subcarriers, thereby causing interference between subcarriers in the system. At the same tim...
