2017-01-09 · 2) Duty Cycle of LTE-U: In the case of designing a duty cycle for LTE-U, multiple LTE TDD frames are considered. For that purpose, ﬁve consecutive LTE frames [12, Fig. 6.2(a)] are used to construct a duty cycle. Similar to [8], the LTE-U transmission ON/OFF condition is used to deﬁne a duty cycle which is shown in Fig. 2 (e.g., 40% duty

LTE-U introduces duty cycle to coordinate the channel utilization between LTE and WiFi devices. Figure 1(b) is a simple example showing how LTE shares the channel with WiFi devices when LTE duty cycle is 50%. In Figure 1(b), LTE allocates and frees the channel during every 20 ms

With T-Mobile already launching LTE-U service in select areas and Verizon not far behind, it’s time to understand what the hype and the technology is all about. Unfortunately that's not true in implementation because LTE-U doesn't know or care about the wifi channel announce timings. By piping up whenever it wants to wifi throughput actually degrades more than 70% at minimum LTE-U duty cycle spec (50%) and up to almost completely, ~99% reduction, at max allowed LTE-U duty cycle (90%) spec. LTE • LTE has been introduced in 2012 in order to provide high data rate mobile broadband connection. It has been introduced to provide 10 times faster datarate compare to 3G. • LTE provides 100 Mbps. • LTE has been specified in 3GPP Rel.8 • LTE supports carrier bandwidth of 20 MHz For LTE System features, READ MORE LTE Advanced and during each period (the so-called duty cycle period, denoted as T), only a portion (de ned by the LTE-U duty cycle ) of the time is utilized for the LTE-U transmission, as shown in Fig.1.

Depending on the interference to noise ratio (INR) being above or below -62dbm, we classify the LTE-U interference as strong or weak and establish mathematical A TDD cycle, or frame, is the minimum amount of time used to communicate in both directions, including gaps for hardware turnaround and over the air propagation delays. When multiple access points (APs) are deployed in the same geographical area, it is important that they all … Specifically, we first design a duty-cycle spectrum sharing framework, which allows an LTE system to share the spectrum with a WiFi system by using time sharing. After that, we develop deep reinforcement learning (DRL)-based algorithms to learn WiFi traffic demands by analyzing WiFi channel activity, e.g., the idleness/business of WiFi channels, which can be observed by the LTE system via Abstract: In this paper, a power saving protocol for public safety-long-term evolution (PS-LTE) with duty cycle adjustment is proposed according to the emergency of PS-LTE-based mobile stations. Because the PS-LTE transceiver consumes power whenever it is active, it is the most efficient to leave the receiver off, and wake it up asynchronously only when needed. Duty cycle is a measure of ON or OFF period as a percentage of total period. Duty cycle is determined by averaging an integral number of periods over a gate time which is selectable from 10 ms to 199.99 s. The same signal is applied to Channels A and B. 10/11 UE behavior.

Pulse Width Modulation (PWM) , duty cycle, pulse width, pwm duty cycle. Standard features of Laureate LTE transmitters include: Ethernet I/O, isolated.

Recent literature demonstrated promising results of Long-Term Evolution (LTE) deployments over unlicensed bands when coexisting with Wi-Fi networks via the Duty-Cycle (DC) approach. However, it is known that performance in coexistence is strongly dependent on traffic patterns and on the duty-cycle ON–OFF rate of LTE. Acknowledgment bundling has been defined for Long Term Evolution (LTE) Time Division Duplex (TDD) systems due to asymmetric DL/UL partitioning.

LOW MODULE COSTS DUE TO REDUCED COMPLEXITY As Mobile IoT’s lower data rates require less processing power in radio chipsets, these can be produced more cost-effectively. To further reduce complexity, a number of unnecessary LTE features In particular, LTE base stations (BSs) measure the utilization of the channel based on channel status information (CSI), learn the channel utilization of WiFi (current and previous), select the optimum duty cycle and transmission power, and perform transmission under this duty cycle, which results in effective sharing of wireless spectrum with WiFi networks.

For Example: Electrical motors use very less duty-cycle. if a motor runs for one out of 200 seconds or 1/200 of the time, then, its duty cycle is 1/200, or 0.5 per cent. If you like our post “What is the Duty Cycle?
