Let’s take a look at a measurement done by a UE in the field. Trial Software Product Updates. A downlink 36.231 corresponds to a set of resource elements used by the physical layer but does not carry information originating from higher layers. If imcs is a scalar, mod is returned 3hpp a single character vector instead of a single element cell array of character vectors.

Agilent’s former Test and Measurement business has become Keysight Technologies. Accordingly, you will see lower error rate Diversity gain in D comparing to C. Each radio frame of length consists of two half-frames of 3gpp each. 3ggpp FDD, 10 subframes are available for downlink transmission and 10 subframes are available for uplink transmissions in each 10 ms interval. Each radio frame is long and consists of 20 slots of lengthnumbered from 0 to 19 see the following figure. It includes components and 11 test benches.
Then compare C and D.
In LTE, they give a special name for each of the way of transmission and it is called ‘Transmission Mode’. Input Arguments collapse all imcs — Modeling and coding scheme indices vector 0, You can use the two antenna in diversity configuration rather than MIMO configuration.
You can use these two antenna in various ways. Evaluations can be made regarding degraded system performance due to system impairments that may include non-ideal component performance. The basic transmission parameters are then specified in more detail in the following table. Submit and Review Support Requests.
A downlink physical channel corresponds to a set of resource elements carrying information originating from higher layers and is the interface defined between All Examples Functions Apps More.
The following downlink physical channels are defined:. Click the button below to return to the English version of the page. These parameters can be roughly divided into two 3gppp You would get pretty good high level picture from them. Each transmission mode determin which path the input data should follow through. This is machine translation Translated by.
Three important blocks in physical layer to determin the transmission mode can be illustrated as follows. The automated translation of this page is provided by a general purpose third party translator tool.

At very high level view, 4×2 is a kind of diversity for 2×2. In this section, I would show you some examples showing the increased communication reliability with a couple of different Transmission Mode.
Redundancy version, returned as a column vector, specified as 0, 1, 2, or 3associated with specified imcs from TS For old workspaces which are created in SystemVue However, you would see much increased error rate in C. For now, there are seven predefined predefined transmission mode as shown in the following table TS All Examples Functions Apps. Created by Greg Miller on Mar 07, The columns of the indexed MCS table entries are returned as separate outputs given by the transport block size index itbs 0, Considering these various possibilities, 3GPP provides several predefined transmission methods and this transmission method is called ‘Transmission Mode’.
Of course, one ways is to use it as 2 x 2 MIMO, but this is not the only way.
