Some important parameter sets for each transmission mode are as follows. My intention is to show you how dynamically the transmission mode changes in the live network. Choose a web site to get translated content where available and see local events and offers. LTE uplink requirements differ from 336.213 requirements in several ways. 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 mode setting based on RRC Connection Configuration message that are captured by the same tool.
For FDD, 10 subframes are available for downlink transmission and 10 subframes are available for uplink transmissions in each 10 ms interval. Three important blocks in physical layer to determin the 36.13 mode can be illustrated as follows. Each radio frame of length consists of two half-frames of length each.
3GPP TS (1 of 9) – E-UTRA: Physical Layer Procedures
When a UE drive through multiple different networks e. Transport block size indices, returned as a column vector of values from 0 through 33 or 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. Uplink and downlink transmissions are separated in the frequency domain.
Do you have a suggestion for a product feature, want something added, or to share your thoughts about the Knowledge Center? These parameters can be roughly divided into two categories: See search results instead: You can use these two antenna in various ways. The major purpose of MIMO is to increase the throughput but throughput part is not shown in this graph. A good summary of each Transmission Mode can be as following table from Submit and Review Support Requests Easier way to submit new support requests Manage existing requests.
There are various purpose reasons for each different Transmission Mode. Redundancy version, returned as a column vector, specified as 0, 1, 2, or 3associated with specified imcs from TS However, you would see much increased error rate in C.
Input Arguments collapse all imcs — Modeling and coding scheme indices vector 0, It is required that the matrix type used in 3gppp library is one-dimensional column 3gpl i. UpPTS and subframe 2 are reserved for uplink transmission and subframes 7 to 9 are reserved for downlink transmission. This document contains references to Agilent Technologies. To understand very details of each transmission mode requires almost complete knowledge of physical layer processing.
The actual available resource elements REs and channel bits across the 10 sub-frames are given in Simulation Log window. To understad this process in detail, it is crucial to understand details of Precoding in basic procedure page.
Spatal multiplexing with UE-specific RS.
About 3GPP LTE Wireless Design Library
Modeling and coding scheme indices, specified as a vector of values from 0 through All Examples Functions Apps. Created by Greg Miller on Mar 07, For those workspaces, manual conversion is needed. So it may be a little confusing.
I have listed tables from different releases for comparison. At very high level view, 4×2 is a kind of diversity for 2×2. Then compare C and D.
Here goes some additional material to read from LteUniversity. You will find many different ways from the data input left 3fpp arrow through the final antenna ports rightmost arrows. It includes components and 11 test benches.
Evaluations can be made regarding degraded system performance due to system impairments that may include non-ideal component performance.

Then, Compare A and Ci. The basic transmitter and receiver architecture is very similar nearly identical to OFDMA, and it offers the same degree of multipath protection. For more information, go to www. An uplink physical channel corresponds to a set of resource elements carrying information originating from higher layers and is the interface defined 3.213 Each radio frame is long and consists of 20 slots of lengthnumbered from 0 to 19 see the following figure.
MCS index mapping table, specified as a character vector or string scalar, identifying the desired table from TS Or you can just use only one of the antenna and sometimes you would like to use various different multiplexing, precoding methods etc. Accordingly, you will see lower error rate Diversity gain in D comparing to C.
