Description

Method and device in communication node for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus for random access.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of multiple application scenarios, a New air interface technology (NR, New Radio) (or 5G) is determined to be studied in 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 guilds, and standardization Work on NR starts after passing through WI (Work Item) of the New air interface technology (NR, New Radio) in 3GPP RAN #75 guilds.

In order to be able to adapt to various application scenarios and meet different requirements, a research project of Non-orthogonal Multiple Access (NoMA) under NR is also adopted on 3GPP RAN #76 time congress, the research project starts at R16 version, and WI is started to standardize the related technology after SI is finished. As a bearing NoMA research project, 3GPP RAN #82 passed WI for two-step random access (2-step RACH) at NR over the second meeting.

Disclosure of Invention

For the R16 and later versions of User Equipment (UE), both two-step random access and the conventional 4-step random access procedure can be used. And the user equipment can switch between 2-step random access and 4-step random access or fall back from 2-step random access to 4-step random access according to the WI requirement of the two-step random access. Because the application scenarios of the 2-step random access and the 4-step random access are different, the performance requirements of the 2-step random access and the 4-step random access may also be different, such as different delay requirements, different coverage requirements, different capacity requirements, and the like. Uplink transmission in the 3GPP 5G NR system can support two waveforms (Waveform), one is DFT-S-OFDM (Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing) and the other is OFDM (Orthogonal Frequency Division Multiplexing), and the two waveforms can meet different coverage requirements and different complexity requirements. In the protocol, these two waveforms are realized by whether Transform Precoding (Transform Precoding) is employed when generating the uplink signal. In existing systems, the waveform of an uplink transmission is related to the waveform used for random access.

The present application provides a solution to the different requirements of 2-step random access and 4-step random access. It should be noted that, without conflict, the embodiments and features in the embodiments in the base station apparatus of the present application may be applied to the user equipment, and vice versa.
