Embodiment 1

[0144] image 3 A schematic diagram of a beam failure recovery process provided by an embodiment of the present invention, the process includes the following steps:

[0145] S301: The UE determines a target reporting manner of beam failure of the first SCell.

[0146] The beam failure recovery method provided by the embodiment of the present invention is applied to a UE.

[0147] The UE may pre-save the criteria for determining the reporting mode of the beam failure of the SCell, so the UE may determine the reporting mode of the beam failure of the first SCell, and the SCell for which the UE determines the target reporting mode of the beam failure may be called the first SCell, The reporting manner of the beam failure of the first SCell may be referred to as a target reporting manner.

[0148] For different SCells, the criteria for determining the target reporting manner of beam failure of the SCell may be the same or different.

[0149] The target reporting manner of the b...

Embodiment 2

[0171] The method of reporting the target of the beam failure of the first SCell may include the bearing method and / or the serving cell used when reporting the beam failure of the first SCell. On the basis of the above embodiments, in the embodiment of the present invention, if the first SCell The target reporting method of the beam failure includes the bearer method when the first SCell beam failure is reported, and the reporting of the beam failure recovery information to the base station using the target reporting method includes at least one of the following:

[0172] Report beam failure recovery information to the base station through a physical random access channel (Physical Random Access Channel, PRACH);

[0173] Report beam failure recovery information to the base station through a Physical Uplink Control Channel (PUCCH);

[0174] Reporting beam failure recovery information to the base station through a physical uplink shared channel (Physical Uplink Shared Channel, P...

Embodiment 3

[0187] On the basis of the above embodiments, in the embodiments of the present invention, if the beam failure recovery information includes candidate beam information, the reporting of the beam failure recovery information to the base station through the PRACH includes:

[0188] Using the information of the candidate beams to determine a PRACH preamble, using the preamble to generate a PRACH signal, and sending the PRACH signal to the base station as beam failure recovery information.

[0189] In the beam failure measurement and recovery process, in order not to affect the normal random access process, the channel used for beam failure recovery may be the PRACH channel. When reporting the beam failure recovery information to the base station through the PRACH, if the beam failure recovery information includes the identification of the Scell ​​with the beam failure and / or information about the candidate beam, the UE uses the identification of the Scell ​​with the beam failure a...

Abstract

The invention discloses a beam failure recovery method, device, UE, base station and readable storage medium. The method includes: the UE determines the target reporting method of the beam failure of the first Scell; if the UE detects that the beam failure of the first Scell ​​occurs , using the target reporting method to report beam failure recovery information to the base station, and the base station performs beam failure recovery of the first SCell according to the detected information of the beam failure event of the first SCell and / or the information of candidate beams. In the present invention, the UE can report the beam failure of the Scell ​​in a more reliable way or a more reliable way selected by the base station, so that the system can recover the beam failure of the Scell ​​in a reliable way of reporting the beam of the Scell.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a beam failure recovery method, device, UE, base station and readable storage medium. Background technique [0002] As low-band resources become scarce, the millimeter-wave frequency band has more spectrum resources and can provide greater bandwidth, and has become an important frequency band for future applications of mobile communication systems. Due to the shorter wavelength, the millimeter wave frequency band has different propagation characteristics from the traditional low frequency band spectrum, such as higher propagation loss, poor reflection and diffraction performance, etc. Therefore, a larger-scale antenna array is usually used to form a shaped beam with greater gain, overcome propagation loss, and ensure system coverage. For the millimeter-wave antenna array, due to the shorter wavelength, the antenna element spacing and the smaller aperture, it i...
