In LTE TDD special subframes are used for switching from downlink to uplink and contain three sections: DwPTS, GP, and UpPTS. But we don't have any special subframe for switching from uplink to downlink. Why?
dear dr ghoslya
The LTE System Toolbox™ product can generate and manipulate signals for the duplexing arrangements specified in the LTE standard. In LTE, downlink and uplink transmissions are organized into radio frames of duration 10ms consisting of 10 consecutive subframes, each consisting of a number of consecutive OFDM symbols.
please check the attachments for more details.
thank you

Hello Sir,
Yes you are correct, but that is not my question. Please check my attachment with the question. In LTE TDD we switch from downlink to uplink and uplink to downlink. there is always a special subframe in between two symbols while switching from uplink to downlink but there is no subframe or guard period while switching from downlink yo uplink. why?
