Visible light communication, due to its high bandwidth, low latency, and small interference area, will be a significant part of 5G along with mmwave. In this paper, a new frame structure has been proposed that implements reserve before transmit scheme. In this scheme, the active portion of ...
5G signals: OFDM waveforms, Frame Structure, and Numerology From the series: 5G Tutorial Learn the basics behind 5G NR waveforms, frame structure, and numerology. This video looks at OFDM waveforms, and the different subcarrier spacings supported in 5G NR. You’ll also learn about the i...
In this paper we present a 5G frame structure designed for efficient support of users with highly diverse service requirements, including mobile broadband (MBB) data, mission critical communication (MCC), and massive machine communication (MMC). The proposed solution encompasses flexible multiplexing of...
To address the challenges posed by the diverse demands of mobile users and vertical industries, it is crucial for 5G-advanced (5G-A) networks to exhibit flexibility in system design across both the physical and higher layers. A single-frame structure alone cannot provide the necessary flexibility...
5G统一帧结构UFS(Unified Frame Structure),一种可参数化缩放的帧结构设计,可在统一的帧结构架构下灵活地提供各类TTI,既保证eMBB/mMTC/uMTC等不同业务共存,也方便进行新业务扩展,从而使得空口系统更加简洁高效。 A. 正确 B. 错误 如何将EXCEL生成题库手机刷题 > ...
In one implementation, least one frame structure for both uplink (UL) and downlink (DL) beam switching is provided. The UL beam switching and refinement may rely on 5G Physical Random Access Channel (xPRACH) or 5G Sounding Reference Signal (xSRS). The DL beam switching and refinement may ...
The Transmit MAC frame structure and/or RLC frame structure are/is different in formats than those from Receive MAC and/or RLC frame structure at each end (i.e., at the UE and/or at the gNB). In the Up-link (UL), the MAC CE is transmitted at the end of the frame while for ...
FRAME STRUCTURE FOR A WIRELESS COMMUNICATION SYSTEM A frame format used in a wireless communication system, more particularly an OFDMA TDD wireless communication system, of the kind comprising a base station and a plurality of fixed or mobile subscriber stations, the base station maintain...
