A physical sidelink shared channel (SL-SCH) is a dedicated wireless communication channel used for direct device-to-device (D2D) communication in cellular networks like 4G LTE and 5G. It facilitates proximity-based services by allowing nearby devices to communicate without routing through a base station. SL-SCH has specialized resource allocation, control signaling, and security measures to support low-latency … Read more
A physical sidelink control channel is a specialized channel in wireless networks, like LTE and 5G, that enables direct communication between devices. It allocates resources, coordinates communication, manages interference, and ensures security for device-to-device (D2D) communication. This is valuable in scenarios where efficient and reliable D2D links are needed, such as public safety and group … Read more
What is a physical channel and a logical channel? A physical channel refers to the actual medium or path through which data is transmitted, such as copper wires, optical fibers, or wireless airwaves. In contrast, a logical channel is a virtual or conceptual channel used to organize and manage data within a communication system, allowing … Read more
5G New Radio (NR) is the cornerstone of 5G wireless technology, operating in diverse frequency bands, utilizing technologies like massive MIMO and beamforming to boost capacity and signal quality. With ultra-low latency, it supports applications from enhanced mobile broadband (eMBB) for high-speed internet to massive machine-type communication (mMTC) for IoT devices. Network slicing enables tailored … Read more
5G New Radio (NR) in unlicensed spectrum involves deploying 5G technology in open frequency bands not exclusively licensed to mobile operators. This approach, often using techniques like License Assisted Access and carrier aggregation, boosts network capacity and coverage by harnessing unlicensed bands such as 2.4 GHz and 5 GHz. It requires careful regulatory compliance and … Read more

The 5G NR SS (Synchronization Signal) block comprises the Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) used for initial cell search, along with Synchronization Reference Signals (SRS) and cell identity information. These signals are transmitted periodically in Synchronization Signal Blocks (SSBs), aiding user equipment (UE) in synchronizing with the cell, identifying it uniquely, … Read more
Ultra-reliable low latency applications, abbreviated as URLLC, are services requiring near-instant data transmission and minimal errors. They are vital in industries like manufacturing, healthcare, and transportation, demanding 5G or beyond networks, network slicing, and edge computing for real-time control and communication. These applications are characterized by their ultra-low latency, high reliability, and critical use cases. … Read more
In 5G, there are various types of registration procedures. Initial Registration (IR) sets up a device’s connection to the network, while Periodic Registration (PR) updates its location. Handover Registration (HR) manages seamless cell-to-cell transitions, Location Update (LU) tracks device movements, and Deregistration (DR) releases resources when a device leaves. Emergency Registration (ER) ensures quick access … Read more
