Problems solved by technology

In terms of power control strategy, the above-mentioned situations are usually not distinguished in the prior art. Full-duplex subframes can adopt exactly the same power control as other subframes. At this time, full-duplex subframes will cause network devices to The received signal-to-noise ratio is lower than expected; or, the network device can configure another set of power control parameters different from other subframes for full-duplex subframes to perform independent subframe-level power control. When the number of UEs increases, use independent The number of subframes for power control parameters increases accordingly, resulting in a significant increase in signaling overhead and affecting network performance

Abstract

The invention relates to the field of wireless communication, specifically to the transmitting power control technology in a wireless communication system. in the transmitting power control method, user equipment uses different power compensation amount to compensate transmitting power for subframes in different subframe sets, and sends data on the subframes through the uplink transmitting power subjected to the transmitting power compensation. According to the scheme provided in the invention, the signal to noise ratio of each uplink subframe is smooth when the full duplex technology is applied, the uplink subframe reception performance is ensured, and excessively large signaling cost is not introduced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the transmission power control technology in the wireless communication system. Background technique [0002] In existing wireless communication networks, frequency division duplex FDD (Frequency Division Duplex) or time division duplex TDD (Time Division Duplex) is usually used to avoid interference between a transmitter and a receiver. If the sending and receiving signals work on the same frequency band at the same time, it is a full-duplex technology. The application of full-duplex to wireless transmission is a research hotspot in recent years. The introduction of full-duplex technology in cellular systems can bring advantages such as improved spectrum efficiency and increased freedom of resource scheduling. The application of full-duplex technology to wireless communication networks needs to solve the self-interference problem of full-duplex equipment. Because the same ...
