Embodiment Construction

[0127] The exemplary embodiments will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. Rather, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0128] In related technologies, in the 5G system, random access is divided into contention-based random access and non-contention-based random access. Among them, random access based on contention is divided into 4 steps.

[0129] Step 1: User equipment (UE) sends a random access preamble to request random access.

[0130] Step 2: The base station feeds back a random access response...

Abstract

The invention relates to a method and a device for transmitting random access indication information. The method comprises the steps of generating indication information related with random accessing;wherein the indication information is used for indicating supporting 2-step competition random accessing or supporting 4-step competition random accessing; and broadcasting system information to theuser equipment, wherein the system information comprises the indication information.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for transmitting random access indication information. Background technique [0002] In related technologies, in 5G (5th generation mobile communication system), user equipment often performs a random access process based on service requirements. In the 5G unlicensed frequency band, the principle of Listen before Talk (LBT) must be observed. Under the LBT principle, it may cause random access delay. In order to improve the success rate of random access, contention-based random access can be shortened to 2 steps. Then, for contention-based random access, the base station and the user equipment can support either a 2-step implementation or a 4-step implementation. However, how to determine which random access method to adopt is an urgent problem to be solved. Summary of the invention [0003] The embodiment of the present invention provides a method...
