Problems solved by technology

[0003] However, the current communication protocol stipulates that the UE can only initiate one random access procedure at the same time. If during a random access procedure, the UE not only needs to request system information from the base station, but also needs to establish an RRC connection with the base station, the UE will not be able to know How to communicate with the base station, so that the request for system information and the establishment of RRC connection cannot be realized

Abstract

The present application provides a wireless communication method and a terminal device. The method includes: determining a target message for carrying a system information SI request, the target message is message 1 or message 3, and the SI request is used to request a network device to send S1: Perform operations related to establishing the RRC connection according to the target message and the time when the RRC connection needs to be established. The method of the embodiment of the present application enables the terminal device to communicate with the network device through an appropriate communication process when it needs to request system information from the network device and establish an RRC connection with the network device during a random access process, so as to realize the system Information request and RRC connection establishment.

Description

technical field [0001] The present application relates to the technical field of communication, and more specifically relates to a wireless communication method and terminal equipment. Background technique [0002] In the fifth-generation (5th-Generation, 5G) mobile communication system, system information (System Information, SI) is divided into two categories, one is the minimum system information (Minimum SI), and the other is other system information (Other system information). SI). Other SI is divided into common system information (Common SI) and cell-specific system information (Cell Specific SI) according to the effective range, where Common SI is system information shared by several cells, and Cell Specific SI is system information for one cell. The Minimum SI is sent to the user equipment (User Equipment, UE) in a periodic broadcast mode, and the Other SI needs to be requested by the UE from the base station, and the UE can request the OtherSI from the base statio...
