LTE-U is an extension of the Long Term Evolution (LTE) standard for operation in unlicensed spectrum. LTE-U differs from WiFi, the predominant technology used in unlicensed spectrum in that it utilizes a duty cycle mode for accessing the spectrum and allows for a more seamless integration with LTE deployments in licensed spectrum. The number of messages is limited due to the duty cycle and payload in combination with the quality offered by the network. The 868 MHz ISM band limits the use of a device to 1% of the time on air. LoRaWAN specifies that each time a message is send in one ISM subband, the device must wait the remaining time of the duty cycle in that band before resending. 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 IoT applications which require more frequent communications will be better served by NB-IoT, which has no duty cycle limitations operating on the licensed spectrum.

Reference Signal - Downlink. Most of the channels (e.g, DPSCH, DPCCH, PBCH etc) is for carrying a special information (a sequence of bits) and they have some higher layer channel connected to them, but Reference Signal is a special signal that exists only at PHY layer. This is not for delivering any specific information. LTE TDD frame structure type 2.

So if Wi-Fi were alone on the channel, it would get 100% of the airtime. With this approach, LTE-U operates over the shared channel periodically (more specifically, the radio resources of LTE-U that reside in the unlicensed spectrum and are shared with Wi-Fi are utilized periodically), and during each period (the so-called duty cycle period, denoted as ), only a portion (defined by the LTE-U duty cycle ) of the time is utilized for the LTE-U transmission, as shown in Figure 1.

Depending on the use case, either throughput, reliability or latency constraints may be the primary concern of the service provider. If you own one of the newer phones equipped with Qualcomm’s X16 LTE modem (e.g. Galaxy S7/S7 Edge, LG V20, Pixel), your phone may soon run on a new technology called LTE-U or LTE Unlicensed. 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.

• 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. of LTE-U duty cycle). 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 For mobile and portable stations using time division duplexing (TDD) technology, the duty cycle must not exceed 38 percent in the 2305-2315 MHz and 2350-2360 MHz bands. Mobile and portable stations using FDD technology are restricted to transmitting in the 2305-2315 MHz band. Duty Cycle in Electrical: Electrical Components uses very less duty-cycle to operate as compared to Electronic Components. For Example: Electrical motors use very less duty-cycle.
