[0054]Seefigure 2 ,figure 2 Is a flowchart of a method for restoring data transmission provided by an embodiment of the present invention, such asfigure 2 As shown, including the following steps:

[0055]Step 201: If the communication link of the high-frequency beam for service transmission between the terminal and the network-side node is abnormal, the terminal receives a trigger signaling that indicates at least one beam set sent by the network-side node.

[0056]In the embodiment of the present invention, the above-mentioned high-frequency beam may be a beam higher than a certain frequency threshold, for example, it may be a beam with a frequency between 6 GHz and 100 GHz, of course, it may also be a beam with other frequencies, for example: 1 GHz or 3 GHz or 5GHz and so on. It should be noted that, in the embodiment of the present invention, the specific frequency of the high-frequency beam is not limited, and the high-frequency beam should be understood as a high-frequency beam under...

[0069]The above trigger signaling may be trigger signaling, and in addition, the trigger signaling may be sent by a network side node through physical layer downlink control information (DCI, Downlink Control Information). In addition, the above trigger signaling can be understood as the signaling that triggers the activation of the beam rapid recovery mechanism, that is, in the embodiment of the present invention, the beam rapid recovery mechanism can be activated based on the signaling.

Abstract

Embodiments of the present disclosure provide a data transmission recovery method, a terminal, and a network side node. The method may comprise: if a communication link of a high-frequency beam for performing service transmission between a terminal and a network side node is abnormal, the terminal receives triggering signaling that is sent by the network side node and that is used for indicating at least one beam set; and the terminal recovers data transmission of a service by means of a target beam in the at least one beam set, the target beam being a target beam determined by the terminal or the network side node in the at least one beam set.

Description

Technical field[0001]The present invention relates to the field of communication technology, and in particular to a method, terminal and network side node for restoring data transmission.Background technique[0002]Since the high frequency band has abundant idle frequency resources, it can provide greater throughput for data transmission. At present, the 3rd Generation Partnership Project (3GPP) has completed the high-frequency channel modeling work. Among them, compared with the low frequency band, the high frequency signal has a shorter wavelength. It is possible to arrange more antenna elements on the panel of the same size, and use beamforming technology to form a beam with stronger directivity and narrower lobes. Therefore, the combination of large-scale antennas and high-frequency communications is also one of the future trends. However, because the high-frequency beam of a large-scale antenna is very narrow, the communication link of the high-frequency beam is prone to abnormal...
