- -application number of the original application: 201610831274.4

The invention of the original application is named: method and device for adjusting transmission power in UE (user equipment) and base station

Technical Field

The present application relates to transmission schemes in wireless communication systems, and more particularly, to methods and apparatus for transmit power adjustment.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of various application scenarios, research on a New air interface technology (NR, New Radio) is decided on 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 global meetings.

In order to be able to flexibly adapt to various application scenarios, future wireless communication systems, in particular NR, may support various mathematical structures (Numerology), which refers to various subcarrier spacings, various symbol time lengths, various CP (Cyclic Prefix) lengths, and so on. The different subcarrier spacings disrupt the orthogonality between subcarriers and thereby cause interference between subcarriers within the system. Meanwhile, since the subcarrier spacing adopted by the new air interface technology may be different from that of LTE (Long Term Evolution), the interference between the new air interface and LTE may be stronger than that between LTE and LTE.

Disclosure of Invention

In the existing wireless communication system (e.g. LTE), the transmit Power of uplink and downlink transmissions can be generally adjusted, but due to the hardware limitation of the transmitter/receiver, the influence of signaling overhead, the limitation of modulation scheme, etc., the PSD (Power Spectrum Density) of uplink and downlink transmissions on different frequencies at any time is not changed in a statistical sense. But within the next generation communication systems, due to advances in hardware and the introduction of various mathematical architectures (Numerology), it has become possible to employ different PSDs at different frequencies. Meanwhile, due to the existence of interference between frequency regions of different mathematical structures (Numerology) within the above-described system and interference between different systems (such as NR and LTE), the spectral efficiency of a system employing a new air interface may be greatly limited.

The present application provides solutions to the problem of interference between frequency regions employing different mathematical structures (Numerology) within a system and/or interference between different systems, such as NR and LTE. By adopting the solution of the application, the interference in the system and/or between the systems can be greatly relieved by adjusting the PSDs with different frequencies, and the frequency spectrum utilization rate is improved. It should be noted that, without conflict, the embodiments and features in the embodiments in the UE (User Equipment) of the present application may be applied to the base station, and vice versa.
