Description

Method and related device for reporting beam measurement Technical Field The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for reporting beam measurement. Background With the rapid development of communication technology, the requirements of the communication system on transmission efficiency and transmission quality are also increasing. For example, the terminal device may measure the quality of the beam between itself and the network device (e.g., the base station), and report beam information such as the quality of the beam to the network device. The network device can find out better wave beams by analyzing the reported wave beam information, which is beneficial to maintaining and improving the performance of the communication system. However, the currently reported beam information may not be comprehensive enough, which easily causes that the network device cannot judge a better quality beam, thereby affecting the performance of the communication system. Disclosure of Invention In order to solve the above problems, the present application provides a method for reporting beam measurement and a related device, and aims to provide a method for reporting beam measurement, in which terminal equipment can report more comprehensive beam information, so that network equipment can conveniently judge a better quality beam, and further maintain and improve performance of a communication system. In a first aspect, the present application provides a method for reporting beam measurement, which is applied to a terminal device. In the method, a measurement result of a first beam is acquired, for example, the measurement result of the first beam may be RSRP or SINR, and then, based on the measurement result of the first beam, first information may be sent, where the first information is used to indicate related information of the first beam and indicate whether there is related information of a second beam, for example, event measurement may be performed on the measurement result of the first beam, a first beam meeting event may trigger reporting of the first information, and for example, event measurement may be performed on other beams except the first beam after the measurement result of the first beam is acquired, other beams meeting events may also trigger reporting of the first information. Illustratively, the related information of the first beam may include an index of the first beam, a measurement result of the first beam, an event satisfied by the first beam, and the like. Therefore, based on the design of the first information, the first information can be more comprehensive and easier to understand, network equipment such as a base station and the like can accurately acquire the relevant information of all beams included in the first information reported by the terminal equipment based on the first information, the problems that the relevant information of the beams acquired by the network equipment is not complete and the like can be avoided, errors caused in judging the better beams are avoided, the network equipment is facilitated to accurately determine the beams with better quality, and therefore the performance of a communication system is maintained and improved. In one possible implementation, the first information may include a number of beams, the number of beams being used to indicate whether there is information about the second beam. For example, a first beam is a serving beam, a number of beams greater than or equal to 1 may indicate that there is information about a second beam in the first information, the beam indicated by the number of beams may not include the first beam, for example, the first beam is a beam other than the serving beam, a number of 1 beams greater than 1, or a sum of all the beams of the first information greater than 1 may indicate that there is information about the second beam in the first information, and the beam indicated by the number of beams may include the first beam. Therefore, the first information can be implicitly indicated by the number of the beams, and whether the first information further comprises the related information of the second beam or not is based on the related information of the first beam, so that network equipment and the like receiving the first information can be more easily understood, the related information of more beams can be accurately obtained, and better judgment of the beams is facilitated. In one possible implementation, the beams indicated by the beam numbers may be in a first cell where the first beam is located, and, illustratively, with a cell as a dimension, one cell may correspond to one beam number, where the beams indicated by the beam numbers corresponding to the cell are. For example, the number of beams corresponding to the first cell, where the indicated beams are all in the first cell. In this way, the network device and the like can determi
