A method for wireless communication, characterized by comprising: when a first terminal device and a second terminal device perform wireless communication via a first network device, measuring, by the first terminal device, link quality of a first link, wherein the first link is a link between the first terminal device and the first network device; and performing, by the first terminal device, a reporting process for link quality of the first link according to a first relationship and a second relationship, wherein the first relationship is a relationship between the link quality of the first link and a predetermined first threshold of quality, the second relationship is a relationship between a first code rate and a recommended code rate, and the recommended code rate is a code rate that, before a current time, the first network device most recently indicates to be used by the first terminal device, wherein the first code rate is: a maximum code rate supported by the second terminal device, or a set of code rates supported by the second terminal device; wherein, when the first relationship is that the link quality of the first link is greater than or equal to the first threshold of quality and the second relationship is that the first code rate is less than the recommended code rate, not reporting, by the first terminal device, the link quality of the first link to the first network device; when the first relationship is that the link quality of the first link is greater than or equal to the first threshold of quality and the second relationship is that the first code rate is greater than or equal to the recommended code rate, reporting, by the first terminal device, the link quality of the first link to the first network device. when a first terminal device and a second terminal device perform wireless communication via a first network device, measuring, by the first terminal device, link quality of a first link, wherein the first link is a link between the first terminal device and the first network device; and performing, by the first terminal device, a reporting process for link quality of the first link according to a first relationship and a second relationship, wherein the first relationship is a relationship between the link quality of the first link and a predetermined first threshold of quality, the second relationship is a relationship between a first code rate and a recommended code rate, and the recommended code rate is a code rate that, before a current time, the first network device most recently indicates to be used by the first terminal device, wherein the first code rate is: a maximum code rate supported by the second terminal device, or a set of code rates supported by the second terminal device; wherein, when the first relationship is that the link quality of the first link is greater than or equal to the first threshold of quality and the second relationship is that the first code rate is less than the recommended code rate, not reporting, by the first terminal device, the link quality of the first link to the first network device; when the first relationship is that the link quality of the first link is greater than or equal to the first threshold of quality and the second relationship is that the first code rate is greater than or equal to the recommended code rate, reporting, by the first terminal device, the link quality of the first link to the first network device. a maximum code rate supported by the second terminal device, or a set of code rates supported by the second terminal device; wherein, when the first relationship is that the link quality of the first link is greater than or equal to the first threshold of quality and the second relationship is that the first code rate is less than the recommended code rate, not reporting, by the first terminal device, the link quality of the first link to the first network device; when the first relationship is that the link quality of the first link is greater than or equal to the first threshold of quality and the second relationship is that the first code rate is greater than or equal to the recommended code rate, reporting, by the first terminal device, the link quality of the first link to the first network device.
