Problems solved by technology

[0006] However, when SCell or BWP is introduced, the BWP can be BWP under PCell or BWP under SCell. Beam failure may also occur in the beam of SCell or BWP. For this situation, it is not clear how to recover from beam failure. Therefore It is necessary to propose a beam failure recovery method for SCell or BWP to clarify how to recover its beam on SCell or BWP when UE beam failure occurs on SCell or BWP

Abstract

The invention provides a beam failure recovery method, terminal equipment and network equipment. The beam failure recovery method comprises the following steps: obtaining resource configuration information, wherein the resource configuration information is used for wave beam failure recovery of an auxiliary cell SCell or a bandwidth part BWP; when detecting that a beam on the SCell or the BWP fails, depending on resource configuration information, and sending a beam failure request message to the network equipment at the corresponding resource position, receiving feedback information of the beam failure request message sent by the network equipment at the corresponding resource position according to the resource configuration information, determining a beam for beam failure recovery according to the feedback information, and performing data transceiving by using the determined beam. According to the scheme provided by the invention, when the SCell or the BWP has the beam failure, the beam or service of the terminal equipment on the SCell or the BWP can be recovered, so that the data loss is avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a beam failure recovery method, terminal equipment and network equipment. Background technique [0002] In the future 5G (5Generation, fifth generation) mobile communication system, in order to achieve the target of 20Gbps downlink transmission rate and 10Gbps uplink transmission rate, high-frequency communication and large-scale antenna technology will be introduced. High-frequency communication can provide wider system bandwidth, and the antenna size can also be smaller, which is more conducive to the deployment of large-scale antennas in base stations and UEs (User Equipment, user equipment). Multi-beam / Multi-TRP (multi-beam / multi-transmitting node) transmission and reception on the base station side, and Multi-beam transmission and reception on the UE side will be widely used. Taking NR PUSCH (New Radio Physical Uplink Sharing Channel, New Radio Physical Uplin...
