LTE Advanced TDD Throughput for Downlink (Coding Rate = 1)

By Azar

 

Previously Semi-realistic throughput was computed for LTE TDD Downlink scenario only with Coding rate = 1.   If you remember or have read the previous article (link here), in the same context

throughput is computed for LTE Advanced in this case for coding rate = 1.  Few important points to remember while look at these throughput values are. The throughput is shown in the table

below the increase in direct proportion to the number of Component carriers because it is assumed that each component carrier has the same configuration. Even though it is not the case in real

practice, for example, one component carrier can have 2 OFDM symbols reserved for PCFICH, PDCCH, and PHICH, while another component carrier can have 3 OFDMA symbols reserved.

 

UL-DL SUBFRAME CONFIGURATION 0

 

Maximum LTE AdvancedTDD Physical Layer Throughput can be achieved by removing control overhead for minimum and maximum PDCCH symbols. The table above shows values for Subframe Configuration 0 and coding rate 1.

 

 

 

 

UL-DL SUBFRAME CONFIGURATION 5

 

Maximum TDD Physical Layer Throughput can be achieved by removing control overhead for minimum and maximum PDCCH symbols. The table above shows values for Subframe Configuration 5 and coding rate 1.
