Description

Method and equipment used for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus related to reception quality reporting in wireless communication.

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 New Radio interface (NR) technology (or fine Generation, 5G) is decided over 72 sessions of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network), and standardization Work on NR is started over WI (Work Item) where NR passes through 75 sessions of 3GPP RAN.

In Communication, both LTE (Long Term Evolution) and 5G NR relate to measurement of signal or channel quality, which is an important significance for accurate determination of Communication quality of a base station or user equipment, reasonable scheduling of resources, and effective coordination of system interference, and may be a fundamental stone with high throughput and high spectrum utilization, and an indispensable function of eMBB (enhanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communication) or eMTC (enhanced Machine Type Communication). Meanwhile, in the Internet of Things in the field of the IIoT (Industrial Internet of Things, in V2X (vehicle to X), in the communication of unlicensed spectrum, in the monitoring of user communication quality, in the optimization of Network planning, in the NTN (Non terrestrial Network, Non-terrestrial Network communication), there are wide applications in the management of wireless resources and the selection of codebooks of multiple antennas.

With the increase of wireless signal quality measurement and reporting applications, higher requirements are put forward on the accuracy and efficiency of reporting, and meanwhile, the compatibility between different versions of different systems needs to be considered during system design.

Disclosure of Invention

In different communication scenarios, the signal quality may vary greatly, for example, in short-range communication, such as industrial internet of things, V2X communication, and even visible light communication, the signal reception level may be high, such as-60 dBm, while in long-range communication, such as large cell, non-terrestrial network communication, and even deep space communication, the signal level may be low, such as-120 dBm. Many bits are required if it is required to report all these possible measurements accurately; if the overhead of the report needs to be reduced and the efficiency is improved, fewer bits can be used, and the fewer bits are difficult to accurately represent various measurement results. On the other hand, if different systems adopt the same reporting mode, the system design is simplified, and the improvement of the compatibility of the system is very helpful. On the other hand, different communication scenarios may coexist. The quality of the signal may also vary significantly within the same communication application.
