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 invention provides wireless communication methods and terminal devices. A method comprises the steps of determining a target message which is used for bearing a system information (SI) request, wherein the target message is a first message or a third message, and the SI request is used for requesting a network device to send SI; and performing an operation related to RRC connection establishment according to the target message and time at which radio resource control (RRC) connection needs to be established. According to the method provided by the embodiments of the invention, in a randomaccess process period, when the terminal device needs to request the system information from the network device and also needs to establish the RRC connection with the network device, the terminal device can communicate with the network device through utilization of a suitable communication process, thereby realizing request of the system information and establishment of the RRC connection.

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...
