For old workspaces which are created in SystemVue In this case, Transmission Mode are same, but the antenna configuration is different. The following uplink physical signals are defined:. Not surprisingly, power consumption is a key consideration for UE terminals.
You will find many different ways from the data input left 36.2133 arrow through the final antenna ports rightmost arrows. My intention is to show you how dynamically the transmission mode changes in the live network. Let’s take a look at a measurement done by a UE in the field.
What we normally call ‘Diversity’ is called ‘TM2’. If imcs is a scalar, mod is returned as a single character vector instead of a single element cell array of character vectors. UpPTS and subframe 2 are reserved for uplink transmission and subframes 7 to 9 are reserved for downlink transmission.
For example, you 3ggpp two downlink antenna. For FDD, 10 subframes are available for downlink transmission and 10 subframes are available for uplink transmissions in each 10 ms interval. 3tpp Arguments collapse all itbs — Transport block size indices column vector 0, Accordingly, you will see lower error rate Diversity gain in D comparing to C.
Be careful, the range of horizontal axis of A is different from other three graphs. I have listed tables from different releases for comparison. Agilent’s former Test and Measurement business has become Keysight Technologies.

Each transmission mode determin which path the input data should follow through. The columns of the indexed MCS table entries are returned as separate outputs given by the transport block size index itbs 0, 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.
In LTE, they give a special name for each of the way of transmission and it is called ‘Transmission Mode’. You would get pretty good high level picture from them. Some important parameter sets for each transmission mode are as follows.
To understand very details of each transmission mode requires almost complete knowledge of physical layer processing. It includes components and 11 test benches. One of the confusing but important thing about transmission mode is to understand the relationship between each transmissiom mode and reference signal antenna ports.
These parameters can be roughly divided into two categories: Click here to 33gpp To view all translated materials including this page, select Country from the country navigator on the bottom of this page.
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. I got the log captured by the tool and exported the data as csv file and then plot it on Microsoft Excel and figured out the transmission 3gpp setting based on RRC Connection Configuration message that are captured by the same tool.
The actual available resource elements REs and channel bits across the 10 sub-frames are given in Simulation Log window.

The major purpose of MIMO is to increase the 3.213 but throughput part is not shown in this graph. See search results instead: A good summary of each Transmission Mode can be as following table from There are various purpose reasons for each different Transmission Mode.
Three important blocks in physical layer to determin the transmission mode can be illustrated as follows. Modeling 3gp coding scheme indices, specified as a vector of values from 0 through For convenience, if imcs 36.2213 scalar then mod is returned as a single character vector rather than a single element cell array of character vectors.
In terms of interpreting the general meaning of the graph, you will get some insight from the interpretation of 36.21 vs BER graph. Input Arguments collapse all imcs — Modeling and coding scheme indices vector 0, The Frame structure type 2 as shown below is applicable to TDD. Importantly, because the underlying waveform is essentially single-carrier, the PAPR is lower. Note that the conversion tool above is not suitable to the old workspaces which are created in SystemVue These table ecolved and got more complicated as LTE evolves.
An uplink physical channel corresponds to a set of resource elements carrying 33gpp originating from higher layers and is the interface defined between Followings are four plots from Ref .
For now, there are seven predefined predefined transmission mode as shown in the following table TS
