5G Explained

关于该系列该视频概述了“ 5G解释”系列的主要目标，并介绍了5G新广播的基本配置。

Introduction to 5G NR PHY了解用例，需求，5G新广播（NR）和LTE之间的一些主要区别，以及5G NR的部署方案。您还将了解5G NR，FR1和FR2的频率范围。

5G Waveforms, Frame Structure, and NumerologyExplore the basics behind 5G NR waveforms, frame structure, and numerology. This video also explains how adaptive bandwidth parts help reduce power consumption.

Downlink Data in 5G NRLearn about downlink data transmission in 5G NR. Explore the downlink shared channel chain, which includes LDPC coding, layer mapping, resource element allocation for PDSCH transmission, PDSCH mapping, and precoding.

Uplink Data in 5G NR了解5G新收音机中的上行链路数据传输，其中包括在下行链路共享的通道链中已经发现的元素，包括LDPC编码，调制方案，层映射，两种类型的Pusch映射和预编码。

Downlink Control Information in 5G NRLearn about downlink control information (DCI) in 5G New Radio, including its content, encoding, modulation, and mapping to the 5G New Radio slot via the PDCCH or physical downlink control channel.

CORESET and PDCCH in 5G NRLearn about CORESETs, to which the physical downlink control channel (PDCCH) gets mapped. The video illustrates CORESETs and PDCCH using an interactive example and shows how search spaces simplify control information decoding.

Uplink Control Information in 5G NRLearn about uplink control information (UCI) in 5G New Radio, including its content, encoding, modulation, and mapping to the 5G New Radio slot via the PUCCH or physical uplink control channel.

Demodulation Reference Signals in 5G NRLearn about demodulation reference signals (DMRS) in 5G New Radio, including their use in channel estimation and the different configurations for signal and multi-user MIMO.

5G NR中的同步信号块了解5G新无线电（NR）中的同步信号块（SSB），该块由主要和次要同步信号和广播通道组成。您还将了解其在同步中的作用。

Initial Acquisition Procedures in 5G NRLearn about initial acquisition procedures, including cell search based on the synchronization signal block (SSB), extraction of the master information block (MIB), and the random access procedure.

Signals for Channel Sounding in 5G NRLearn about the signals in 5G New Radio (NR) that enable channel sounding. Those signals include the channel state information reference signals (CSI-RS) on the downlink and sounding reference signals (SRS) on the uplink.
