LTE Frame structure. Each radio frame will have total 10 subframes,each subframe will have 2 time slots. subframe configuration is based on Uplink downlink configuration (0 to 6). Usually in all the cases, subframe #0 and subframe#5 is always used by downlink. The Special subframe carry DwPTS (Downlink Pilot Time Slot),GP (Guard Period)... LTE Device Requirements for Verizon Wireless - LTE University TD-LTE defines one or two special subframes in a 10 ms frame. The special subframe has three parts- DwPTS (Downlink Pilot Time Slot), GP (Guard Period), and UpPTS (Downlink Pilot Time Slot). DwPTS and UpPTS are legacy terms from TDD version of UMTS (Universal Mobile Telecommunication System); formally, there is no "pilot" channel in LTE. LTE TDD Special Subframe and Its significance for Cell ... Whereas 10 ms periodicity frame has only one Special subframe as subframe #1 . A Special subframe has three past DwPTS(Downlink Pilot Time Slot),GP (Guard Period) and UpPTS (Uplink Pilot Time Slot) and all of these have configurable lengths while the sum of the lengths has to be 1 ms or 14 symbols.

Explain LTE Frame Structure both for FDD and TDD - Techplayon As LTE FDD is full duplex system, means both the downlink and uplink transmission happens at the same time at different frequencies. Type 2: TDD Frame Structure. In TDD, the transmission is divided into time domain, means at one moment of time either downlink subframe is transmitted or uplink. LTE TDD Technology Overview - SlideShare LTE TDD Technology Overview 1. 1 LTE TDD Technology Overview By Maria Djanatliev Abstract To keep pace with the rapidly increasing demands being placed on mobile radio systems and data traffic, the 3rd Generation Partnership Project (3GPP) has standardized a further development of UMTS. e3yn :: TD-LTE (LTE-TDD) 음성서비스와 같이 상 하향간의 조화가 잘 이루어져야 하는 경우 Special Subframe 이라고 하여 전환 스위치가 5ms간격으로 총 두번이 들어가게 된다. 이 Special Subframe의 구조는 DwPTS(Downlink Pilot Time Slot), GP(Guard Period), UpPTS(Uplink Pilot Time Slot) 세가지로 구성된다.

Radio Frames In LTE - IET Engineering Communities For normal cyclic prefix (CP), each slot contains seven OFDM symbols, and in case of extended cyclic prefix, 6 OFDM symbols are slotted‐in in each time slot. The different lengths of CP are indicated in previous table. In the LTE downlink, a constant subcarriers spacing of 15 kHz is utilized. In the frequency domain, 12 subcarriers are ...
