A downlink signal corresponds to a set of resource elements used by the physical layer but does not carry information originating from higher layers.
These parameters can be roughly divided into two categories: You will find many different ways from the data input left most arrow through the final antenna ports rightmost arrows.
UpPTS and subframe 2 are reserved for uplink transmission and subframes 7 to 9 are reserved for downlink transmission. The Frame structure type 1 as shown below is applicable to both full duplex and half duplex FDD. Be careful, the range of horizontal axis of A is different from other three graphs. The following downlink physical channels are defined:. Let’s take a look at a measurement done by a UE in the field. The following downlink physical signals are defined:.

However, you would see much increased error rate in C. Both 5 ms and 10 ms switch-point 36.231 is supported. A downlink physical channel corresponds to a set of resource elements carrying information originating from higher layers and is the interface defined between The output from the encoding process is the channel bits given by the size N bits see Channel Bits Calculationwhich will be sent to Symbol Modulation transmitted in the given subframe.
My intention is to show you how dynamically the transmission mode changes in the live network. Created by Greg Miller on Mar 07, The actual transport block sizes, channel bits and code rates across the 10 sub-frames are given in Simulation Log window when DisplayMsg is set to Simple or Full in DL.
For now, there are seven predefined predefined transmission mode as shown in the following table TS Contact an Expert Contact us 3gop business-related or technical support issues.
Refer to Dynamic Data Flow Simulation for how to set matrix data. The major purpose of MIMO is to increase the throughput but throughput part is not shown in this graph. One of the confusing but important thing about transmission mode is to understand the relationship between each transmissiom mode and reference signal antenna ports.
The columns of the indexed MCS table entries are returned as separate 36.13 given by the transport block 3.6213 index itbs 0, A good summary of each Transmission Mode can be as following table from Modeling and coding scheme indices, specified as a vector of values from 0 through The following uplink physical signals are defined:. If imcs is scalar, mod is returned as a single character vector instead of a single element cell array of character vectors.
In case of 5 ms switch-point periodicity, UpPTS and subframes 2 36.2133 7 are reserved for uplink transmission. The basic transmitter and receiver architecture is very similar nearly identical to OFDMA, and it offers the same degree of multipath protection.
First compare A with B. Some important parameter sets for each transmission mode are as follows.
Select a Web Site Choose a web site to get translated content where available and see local events and offers. For example, you have two downlink antenna. Then compare C and D.

Then, Compare A and Ci. This is machine translation Translated by. In this section, I would show you some examples showing the increased communication reliability with a couple of different Transmission Mode.
Output Arguments collapse all itbs — Transport block size indices column vector 0, Or you can just use only one of the antenna and sometimes you would like to use various different multiplexing, precoding methods etc.
For convenience, if imcs is scalar then mod is returned as a single character vector rather than a single element cell array of character vectors. Click here to see To view all translated materials including this page, select Country from the country navigator on the bottom of this page.
At very high level view, 4×2 is a kind of diversity for 2×2. Redundancy version, returned as a column vector, specified as 0, 1, 2, or 3associated with specified imcs from TS The actual available resource elements REs and channel bits across the 10 sub-frames are given in Simulation Log window.
MathWorks does not warrant, and disclaims all liability for, the accuracy, suitability, or fitness for purpose of the translation.
The Frame structure type 2 as shown below is applicable to TDD. Three important blocks in physical layer to determin the transmission mode can be illustrated as follows. Two radio frame structures are supported:. To understad this process in detail, it is crucial to understand details of Precoding in basic procedure 33gpp.
Note that the conversion tool above is not suitable to the old workspaces which are created in SystemVue
