Abstract

The embodiment of the invention discloses a method for detecting link quality and terminal equipment, and the method comprises the steps that the terminal equipment receives a first event reported bya first protocol layer on a second protocol layer, wherein the first event is used for indicating that the quality of signals in a first signal set is poor and meets a first condition; and the terminal equipment determines, on the basis of the first event, that a second event occurs on the second protocol layer, the second event being used for indicating that a link corresponding to the signals inthe first signal set is poor in quality and satisfies a second condition. The method and the terminal equipment provided by the embodiment of the invention are beneficial to improving the signal transmission performance.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, relate to a method for detecting link quality and a terminal device. Background technique [0002] In the research of fifth generation (5G) mobile communication technology, beamforming technology is an important technology for improving coverage and spectrum efficiency. Beamforming is a signal preprocessing technology based on antenna arrays, which generates directional beams by adjusting the weights of the transmitted signals on each antenna array element. [0003] Network devices can use different beams to send multiple signals, and terminal devices can measure the received signals to determine whether the link for transmitting these signals is too bad to be unavailable, that is, to determine whether the transmission beams used by these signals are available. , that is beam failure, how to judge beam failure currently has no reference scheme.
