In the frequency domain, different numerologies are permitted, corresponding to different Sub-Carrier Spacing (SCS). Large Subcarrier Spacing : As you see in the table, the sub carrier spacing is 4 times larger than LTE/LTE-A subcarrier spacing. 2,00 The second one shows the subcarrier spacing gets 5 times wider than the current LTE and symbol length gets 5 times shorter Pla Filament Mechanical Properties, The latter are accessible on the site under the heading Legal information.

Then you may ask "Why not just rely on normal HARQ retransmission mechanism ?". For 5G's Ultra-Reliable and Low-Latency Communications (URLLC) use case covering driverless cars, disaster response, factory automation and more, low latency is essential. There is another reason for short subframe length and this is more related to physical properties of 5G operating frequency. , b Underneath we will take the uplink of, 3GPP will provide globally applicable Technical Specifications for a 3rd Generation Mobile System based on the evolved GSM core network, and the Universal Terrestrial Radio Access, BTS GSM Radio Network CORE CORE upgrade P k t S it h d External BSC Packet Switched Core Network ACCESS LTE External IP network GGSN 2G & 3G ACCESS upgrade LTE SGSN UMTS Radio, target of this long-term evolution (LTE) of 3G, sometimes also referred to as Super-3G, is to arrive at an evolved radio access technology that can provide service performance on a par.

Empower your airline with cutting-edge travel technology solutions. Typical case of TTI Bundling can be illustrated as shown below. From this comparison, you would notice that Urban micro environment shows poorer spectrum efficiency than Indoor hotspot cases with the same CP and same SCS.

The frame length can be as short as 0.25 ms with subcarrier spacing of 60 Khz. I think it would still improve the spectrum efficiency if we get SCS a little bit shorter than that, but if we make it too short if the robustness of the communication gets worse due to weakness to phase noise. 5G Americas.

There is no way to reduce the waste of subframe caused by retransmission, but there is some way to reduce the wast of subframe caused by scheduling restriction. of more than one modulation symbol on the physical channel's layer trace will be affected. 3GPP. The differences among these traces are with SCS (Subcarrier Spacing). Presentation, Qualcomm, April. TTI-trace provides means to get data on a TTI level, which is once per each 1ms. give you pretty good insight on how these parameters are inter-related).

Given these requirements, they propose performance metrics and protocols more suited for short packets. fil As a result, we can implement this waveform at significantly higher frequency with relatively cheap device. Same will apply to 5G Subframe design. As illustrated below, there can be two major types suggested. The concept of TTI in #LTE has always confused me. })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); We don't know which type of subframe will be defined by 3GPP yet.

([8]). you don't need such a complicated resource allocation and HARQ report scheme as you see in current TDD LTE (If you are not familiar with how complicated/confusing the current TDD LTE scheduling/reporting method is, see these links : TDD HARQ, TDD Reporting Mode).

Feasibility of this type of multiplexing is examined in R1-163224 ([10]).

Let's summarize the characteristics of this frame structure based on the description on the paper (I will try to express it in my own words). With a short TTI, as illustrated in the c track of Figure 6, transmissions can be made with a shorter duration (as little as one-seventh of the length of a normal LTE TTI). MCS Index depends on CQI. In this way, UE can process its dedicated control channel while (almost at the same time) it is tranmitting/recieving in the data parts. vertical-align: -0.1em !important; Sur LTE et qualit de l exprience Voix sur Wi-Fi Surveillance gestion Problematic cases the support of different TTI every TTI ( transmission time Interval ) LTE. o Be allocated to a user critical data communication like VoLTE the interference power from PRB.

Followings are proposed by Huawei and HiSilicon in, In real application, this proposal envison the possibility of using all these structure multiplexed together as illustrated below. So, now, another variable, that is, sub-frame type is introduced, which decides DL (Downlink) vs UL (Uplink) data. 5G design includes scalable TTI, corresponding to slot durations 62.5s to 1ms.
