Embodiment 1

[0123] In Example 1, there is only one time range. In Example 2, on the basis of Example 1, in K continuous time ranges, if X is less than or equal to a certain threshold, the terminal judges that the current link re-enters better condition.

[0124] Example 3:

[0125] After the terminal judges that the beam failure occurs (that is, judges that the current link quality is poor), within a time range, according to the total number of received beam failure instances X is less than or less than or equal to a certain threshold (this threshold can be specified by the protocol or configured by the network) , the UE judges that the current link has re-entered a better state. This threshold can be 0.

[0126] The above-mentioned time range can be realized by using a timer or by other methods; the above-mentioned time range can be preset on the terminal or configured by the network.

[0127] Example 4:

[0128] In Example 3, there is only one time range. In Example 4, on the basis ...

Embodiment 2

[0171] The UE measures the link quality corresponding to the signal in q0, and if the link quality is worse than the corresponding threshold, it notifies the upper layer. Based on the notification from the lower layer, the upper layer judges if a beam failure is sent (for example, if N notifications are received continuously, the notification link quality is worse than the corresponding threshold); the upper layer continues the follow-up process:

[0172] Turn on the timer used to control the beam failure recovery procedure;

[0173] Notify the lower layer to report one or more signals in q1 that meet the threshold;

[0174] send beam failure request;

[0175] Detect the corresponding response from the network side in the specified window;

[0176] At the same time, the lower layer continues to measure and report q0, and the upper layer continues to judge according to the reported notification information. If it is judged that the current beam failure does not occur, the UE ...

Abstract

The embodiment of the invention provides a wireless communication method and a terminal, and provides a processing scheme when the link difference of a signal is not available, so that the power consumption of the terminal can be saved, or the performance of beam failure recovery can be improved. The method comprises the following steps: the terminal reports a first event to a second protocol layer at a first protocol layer; the terminal is based on the occurrence condition of the first event in the second protocol layer; under condition that a second event occurs is determined, the terminal stops measuring the quality of the signals in the first signal set at the first protocol layer; and / or judging on the first event is stopped, and / or reporting of the first event to the second protocollayer is stopped, or the quality of the signal in the first signal set at the first protocol layer by the terminal can be measured continuously, and / or the first event is determined continuously, and / or the first event to the second protocol layer is reported continuously.

Description

[0001] This application is a divisional application of the PCT international patent application PCT / CN2018 / 075691 with the filing date of February 07, 2018, which entered the Chinese national phase with the Chinese patent application number 201880067258.X, and the title of the invention is "wireless communication method and device". technical field [0002] The present application relates to the communication field, and more particularly, to a wireless communication method and device. Background technique [0003] 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. [0004] Network devices can use different beams to send multiple signals, and terminal devices can measur...
