The actual available resource elements REs and channel bits across the 10 sub-frames are given in Simulation Log window.
Transport block size indices, returned as a column vector of values from 0 through 33 or All Examples Functions Apps.
This is machine translation Translated by. Uplink and downlink transmissions are separated in the frequency domain.

Both 5 ms and 10 ms switch-point periodicity is supported. A downlink signal corresponds to a set of resource elements used by the physical layer but does not carry information originating from higher layers. Accordingly, you will see lower error rate Diversity gain in D comparing to C.
Here goes some additional material to read from LteUniversity. Each radio frame of length consists of two half-frames of length each. See search results instead: Translated by Mouseover text to see original. The basic transmitter and receiver architecture is very similar nearly identical to OFDMA, and it offers the same degree of multipath protection.
The Frame structure type 2 as shown below is applicable to TDD. Evaluations can be made regarding degraded system performance due 3pp system impairments that may include non-ideal component performance. The supported uplink-downlink allocations are listed in Table 2 where, for each subframe in a radio frame, “D” denotes the subframe is reserved for downlink transmissions, “U” denotes the subframe is reserved for uplink transmissions and “S” denotes a special subframe with the three fields DwPTS, GP and UpPTS.
One of the confusing but important thing about transmission mode is to understand the relationship between each transmissiom 3pp and reference signal antenna ports. In terms of interpreting the general meaning of the graph, you will get some insight from the interpretation of SNR vs BER graph.
You will find many different ways from the data input left most arrow through the final antenna ports rightmost arrows. Do you have a 36.231 for a product feature, want something added, or to share your thoughts about the Knowledge Center?

MathWorks does not warrant, and disclaims all liability for, the accuracy, suitability, or fitness for purpose of the translation.
To understad this process in detail, 3ypp is crucial to understand details of Precoding in basic procedure page. Trial Software Product Updates. Three important blocks in physical layer to determin the transmission mode can be illustrated as follows.
About 3GPP LTE Baseband Verification Library – SystemVue – Keysight Knowledge Center
You can use the two antenna in diversity configuration rather than MIMO configuration. Considering these various possibilities, 3GPP provides several predefined transmission methods and this transmission method is called ‘Transmission Mode’. For old workspaces which are created in SystemVue In LTE, they give a special name for each of the way of transmission and it is called ‘Transmission Mode’.

Reserved values of itbs are returned as NaN and reserved values of mod are returned as the empty character vector. A good summary of each Transmission Mode can be as following table from For those workspaces, manual conversion is needed.
The following downlink physical channels are defined:. Let’s take a look at a measurement done by a UE in the field. Of course, one ways is to use it as 2 x 2 MIMO, but this is not the only way. This document contains references to Agilent Technologies. Output Arguments collapse all itbs — Transport block size indices column vector 0,
