Overview In Release 15 of the 3rd Generation Partnership Project (3GPP) 5G new radio (NR), the basic handover is mainly based on the long-term evolution (LTE) handover mechanism in which a network controls mobility of user equipment (UE) based on measurement reports from UE. In the basic handover, a source next generation Node B (gNB) … Read more
Overview Signals for transitioning to a radio resource control (RRC) connected state and maintaining the RRC connected state could cause overheads (e.g., power consumption and delay) to a wireless device having a small amount of data to transmit when in an RRC idle state or an RRC inactive state. The 3rd Generation Partnership Project (3GPP) … Read more
Along the long road 3GPP has traversed towards realization of cellular technologies operating in unlicensed bands, evolutions have taken place across the wireless industry and real-world applications, shaping, and at times, altering the expectations, design goals, and foundations of the technology. This paper provides an insight into such evolutions as well as brief descriptions of … Read more
On July 4th, 2019, twenty-one of the twenty-eight European Union (EU) countries voted against a European Commission plan that would have effectively shut out 4G/5G cellular communications as an option for vehicle-to-everything (V2X). This decision gives cellular V2X (C-V2X) a major boost. V2X works to allow traffic elements (such as vehicles, roadside infrastructures, networks, and … Read more
Coexistence of Wi-Fi and LTE-Unlicensed (LTE-U) technologies has drawn significant concern in industry. In this paper, we investigate the Wi-Fi performance in the presence of duty cycle based LTE-U transmission on the same channel. More specifically, one LTE-U cell and one Wi-Fi basic service set (BSS) coexist by allowing LTE-U devices to transmit their signals … Read more
In mission critical situations, communications among responders must maintain a high level of reliability, availability, quality of service and security in scenarios that go beyond the limits that are stipulated in a commercial wireless network. The 3rd Generation Partnership Project (3GPP) Technical Specification Group on Service and System Aspects (TSG-SA) has developed a series of … Read more
Herndon, VA – Fifth generation (5G) wireless networks are expected to support massive connectivity, high capacity, ultra-reliability and low latency. Such diverse use case scenarios require disrupting approaches for the realization of future 5G systems. It is envisioned that multiple transmission and reception points (multi-TRPs) will be vital in 5G in order to improve reliability, coverage, … Read more
Ofinno Technologies announced today that it has filed more than 100 patents on LTE-Advanced Pro Technologies. LTE-Advanced Pro is a natural evolution of Long Term Evolution (LTE), offering speeds of up to multiple Giga bits per second over cellular wireless networks. Wireless vendors and service operators are implementing LTE-Advanced Pro as part of the 5G … Read more
There are all kinds of technologies used to increase network performance. With today’s high demand users, the drive to better, more efficient networks has never been stronger. Though there are many very interesting innovations, the end result must be the same: a better user experience for device users. When the user has a better experience, … Read more
The rapidly growing demand of wireless network services has led the mobile network operators (MNOs) to consider the possibility of exploring unlicensed spectrum to offload the data traffic from the licensed bands. Most recently, 3GPP and other industry alliances are considering extending LTE into the unlicensed spectrum to offload part of the LTE data traffic. … Read more
