Problems solved by technology
[0004] On the one hand, if figure 1 A schematic diagram of an indication method of differentially reported beam quality in the prior art shown, if there is a part of the beam quality that actually needs to be reported that is greater than the threshold value but less than the minimum value of the differentiated beam quality, this part The beam quality should be reported, but this part of the beam quality cannot be quantified in the differential range, so it cannot be reported, and the base station cannot obtain accurate beam quality
[0005] On the other hand, if figure 2 A schematic diagram of another indication method of differentially reported beam quality in the prior art shown in figure 2 In , the differential indication information of the beam quality in interval 1 and interval 2 is the same, but the beam quality below the threshold should not be reported, so that the network device cannot obtain accurate beam quality

The present application discloses a communication method and device. The method includes: a terminal device receiving a reference signal sent by a network device; measuring the reference signal to obtain at least one beam quality; and reporting set differential beam quality indication information to the network device, wherein the set differential beam quality The beam quality indication information is used to indicate that the beam quality reporting is abnormal, and / or the set differential beam quality indication information is used to indicate that the beam quality corresponding to the set differential beam quality indication information is a set value. Corresponding devices are also disclosed. With the solution of the present application, the set differential beam quality indication information is used to indicate that the beam quality reporting is abnormal or to indicate that the beam quality is a set value, so that the beam quality can be accurately reported.
Description
technical field [0001] The present application relates to the technical field of communication, in particular to the reporting of beam quality. Background technique [0002] In a new generation wireless (new radio, NR) communication system, a beam is used for transmission, that is, a higher antenna array gain can be achieved by sending a signal towards a specific direction in space. After receiving the reference signal sent by the base station, the terminal device needs to report the beam quality of the received reference signal, so as to realize beam alignment. [0003] Currently, the beam quality is reported in a manner of reporting a reference value and a differential beam quality. However, the current reporting method has the following problems: [0004] On the one hand, if figure 1 A schematic diagram of an indication method of differentially reported beam quality in the prior art shown, if there is a part of the beam quality that actually needs to be reported that i...
