Embodiment 1

[0046] If the detection values ​​of the reference signals are all lower than the first threshold in N consecutive time periods, an out-of-synchronization OOS indication is reported to a high layer.

Embodiment 2

[0048] If the detection value of the reference signal is lower than the first threshold but higher than or equal to the second threshold in N consecutive time periods, reporting an OOS indication to the upper layer; and

[0049] If the detection value of the reference signal is lower than the second threshold in N consecutive time periods, report the first indication to the high layer.

Embodiment 3

[0051] If the detection value of the reference signal in N consecutive time periods is lower than the third threshold, a beam failure event BFI indication is reported to the upper layer.

Abstract

The embodiment of the present invention discloses a wireless link status indication reporting method and a terminal device, which are used to solve the problem that the terminal equipment needs to report the status indication in each time period, and the interaction overhead between layers is large. The above method can be executed by a terminal device, including: detecting a reference signal; if the reference signal is not detected in N consecutive time periods, reporting a status indication to a higher layer, where N is a positive integer and N≥2. The embodiment of the present invention fully considers the situation that the network device may not be able to send the reference signal in some time period due to the busy channel, which is beneficial to reduce the inter-layer interaction.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method for reporting a wireless link state indication and a terminal device. Background technique [0002] The unlicensed frequency band is one of the effective ways to solve the shortage of spectrum resources in the mobile communication network. By extending the New Radio (NR) technology in the licensed frequency band to the unlicensed frequency band, the capacity and performance of the system can be improved. [0003] In the NR system, the unlicensed frequency bands are mainly in the 5GHz, 37GHz and 60GHz frequency bands. However, there are many devices with different wireless access technologies running on the unlicensed frequency band, such as wireless routers, radars, Bluetooth devices, etc. Listen before speaking" (Listen BeforeTalk, LBT) process. The sending node (network device or terminal device) to perform data transmission needs to listen to...
