DwPTS - Downlink Pilot Time Slot GP - Guard Period UpPTS - Uplink Pilot Time Stot. These three fields are also used within TD-SCDMA and they have been carried over into LTE TDD (TD-LTE) and thereby help the upgrade path. The fields are individually configurable in terms of length, although the total length of all three together must be 1ms. 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. What is LTE frame structure? - Quora LTE Subframes then consist of two slots - in other words there are ten LTE subframes within a frame. The frame structure for the type 2 frames used on LTE TDD is somewhat different. The 10 ms frame comprises two half frames, each 5 ms long. The LTE half-frames are further split into five subframes, each 1ms long. LTE: 2014 - worldoflte.blogspot.com The duration of one LTE radio frame is 10 ms. One frame is divided into 10 subframes of 1 ms each, and each subframe is divided into two slots of 0.5 ms each. Each slot contains either six or seven OFDM symbols, depending on the Cyclic Prefix (CP) length. The useful symbol time is 1/15 kHz= 66.6 mircosec.
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.
The LTE half-frames are further split into five subframes, each 1ms long. Type 2 LTE Frame Structure (shown for 5ms switch point periodicity). The subframes may be divided into standard subframes of special subframes. The special subframes consist of three fields; DwPTS - Downlink Pilot Time Slot; GP - Guard Period; UpPTS - Uplink Pilot Time Stot.

Apr 18, 2018 · 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.
