Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] When describing the embodiments of the present invention, some concepts used in the following description are explained first.

[0052] In the LTE and NR systems, the UE detects whether RLF occurs through a radio link monitor (RadioLink Monitor, RLM) function. After determining the RLF, the UE executes a corresponding link recovery procedure.

[0053] RLM and RLF are only executed on PCell and PScell.

[0054] RLM and RLF on PCell

[0055]In the RLM function of LTE, UE realizes by measuring the Signal to Interference plus Noise Ratio (SINR) of the Cell Reference Signal (CRS) corresponding to the PCell Physical Downlink Control CHannel (PDCCH) Monitoring of wireless links. When the UE physical layer (L1) measures that the SINR of the CRS c...

Abstract

The invention provides a wireless link failure information processing method, terminal and network equipment, and relates to the technical field of communication. The information processing method of radio link failure is applied to the terminal, including: judging whether the first condition is established; if the first condition is established, sending the main serving cell group MCG radio link failure to the secondary serving cell group SCG information; receiving MCG reconfiguration information sent by the SCG; wherein, the first condition at least includes: a failure occurs in a radio link between the terminal and the MCG. The above solution avoids the problem that the ongoing transmission of the terminal needs to be suspended for a long time due to the triggering of the RRC reconstruction process when an RLF occurs between the terminal and the MCG, so as to ensure the rapid recovery of data transmission and improve user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information processing method for wireless link failure, a terminal and network equipment. Background technique [0002] Dual connectivity is a technology introduced in Long Term Evolution (LTE), and will also be used in New Radio (New Radio, NR). It means that user equipment (User Equipment, UE, also called terminal) can be connected to two base stations at the same time, and the two base stations provide data sending and receiving services for the UE at the same time. Since the wireless resources of two base stations can be used at the same time, the service data transmission rate of the UE is doubled. [0003] There is a signaling interface between two base stations serving the same UE, and configuration information of related UEs can be exchanged. [0004] The serving base stations of the dual connectivity UE may belong to the same network standard (RAT), ...
