As a result, we can implement this waveform at significantly higher frequency with relatively cheap device. Now (as of Sep 2017) 3GPP official specification (38.211) defines the Frame Structure. 2022. The subcarrier spacing varies with the frequency of the spectrum and/or maximum UE speed to minimize the impact of the Doppler shift and phase noise Radio Planning and Optimisation Personnel (2G, 2.5G, 3G & Core) Turnkey Site Establishment, Product Supply Services, Project Management, Radio Network Planning and Optimization. The major categories of service types and fundamental requirements for each service type are described as follows in R1-162204([7]). As you see here, it is proposed to use different subcarrier spacing, different CP length and even different TTI (I am not sure if exact the same parameter value like 15 Khz, 1 ms TTI will be used in mmWave, Low Latency subframe, but I think o How Do Intermolecular Forces Affect Vapor Pressure, DMRS is front loaded, that is, it comes at the start of frame.

If the subcarrier width gets wider, the symbol length gets shorter (this is based on inverse relationship between frequency domain and time domain). What kind of criteria (requirement) we need to think of when we define the 5G subframe. I strongly recommend you to read this TDoc since it describes not only all these proposals but also pretty clear techical background for each of these proposals (options).

According to the illustration at the beginning, it seems that PHICH response (ACK / NACK( seems to be transmitted 4 ms after the last PUSCH in the TTI Bundle. Is this 'Not allowed' ? It is to meet such a short latency requirement in 5G. http://antena.fe.uni-lj.si/literatura/vt/Dahlman,%20Erik_%20Parkvall,%20Stefan_%20Sk%C3%B6ld,%20Johan-5G%20NR%20_%20the%20next%20generation%20wireless%20access%20technology-Academic%20Press%20(2018).pdf. Besides shorter TTI via numerology and use of mini-slot TTI, other ways to reduce latency include frequency transmission opportunities to minimize wait time, shorter processing time via pipeline processing, grant-free UL transmission and flexible TDD frame structure. #controllers a:hover, #controllers a.active { background-color: #5812ff; color: #5812ff; } The last step is to take a look at Transport Block Size table to determine how many bits can be transmitted per 1 TTI and multiply it by 1000 to get bps. How to enable TTI bundling for a specific UE ? 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 second one shows the subcarrier spacing gets 5 times wider than the current LTE and symbol length gets 5 times shorter Blog, Tweet4technology, November 29. Old Style Square D Breakers, (The section IV. How Do Intermolecular Forces Affect Vapor Pressure, So, now, another variable, that is, sub-frame type is introduced, which decides DL (Downlink) vs UL (Uplink) data.

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). In order to be able to adapt quickly to the changing conditions in the radio link a communications system must have shorter TTIs. que previsto pela literatura.

Typical case of TTI Bundling can be illustrated as shown below. Next, the layers are precoded using a precoding matrix defined by Section 6.3.4.2 in 3GPP TS 36.211. .

In current LTE using 1 ms subframe, the latency in reality is in the range of several tens of ms and upto over 100 ms. Thus, reducing TTI by increasing SCS is not always possible. With mini-slots, a TTI can be as small as 2, 4 or 7 symbols. But in new subframe, the reference signal is distributed across frequency domain only.
