Each 10 ms radio frame consists of two half-frames of 5 ms each. Each half-frame consists of eight slots 0.5 ms long and three special fields: Downlink Pilot Time Slot (DwPTS); Guard Period (GP); and Uplink Pilot Time Slot (UpPTS). The length of DwPTS and UpPTS is configurable subject to the total length of DwPTS, GP, and UpPTS being equal to 1 ms. LTE Signaling: Troubleshooting and Optimization: January 2012 LTE defines two basic switch point interval durations of 5 and 10 ms. A switch point is a designated subframe divided into three zones which are already known from basic UMTS TDD: Downlink Pilot Time Slot (DwPTS), GP, and Uplink Pilot Time Slot (UpPTS). Other subframes are used for either UL or DL transmission. TD-LTE: Greater Flexibility, New Challenges prevent overlap between uplink and downlink signaling, TD-LTE uses a Guard Period (GP, as shown in Figure 1) in which no data is transmitted. The GP occurs inside the special subframe, which also includes a variable amount of downlink information in the Downlink Pilot Time Slot (DwPTS) and uplink signaling in the Uplink Pilot Time Slot (UpPTS).

LTE • Standardization effort started in late 2004 – With HSPA (downlink and uplink), UTRA will remain highly competitive for several years – IEEE is standardizing mobile WiMAX => Threat for loosing competitive edge • LTE focus: – Enhancement of the UTRA – Optimisation of the UTRAN architecture

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 resource v10 - Creating Web Pages in your Account a special subframe carrying three fields of switch information: Downlink Pilot Time Slot (DwPTS), Guard Period (GP) and Uplink Pilot Time Slot (UpPTS). If the switch time is 10 ms, the switch information occurs only in subframe one. If the switch time is 5 ms, the switch information occurs in both half frames, first in subframe one, LTE Physical Layer Fundamentals and Test Requirements LTE Physical Layer Fundamentals and Test Requirements Fanny Mlinarsky octoScope.

Let's Learn LTE: LTE Radio Frames - Blogger Air Interface For 3G LTE. Manage the different types of information that needs to be carried between the eNodeB and the User Equipment. The frame structures for LTE differ between the Time Division Duplex, TDD and the Frequency Division Duplex, FDD; Two adjacent slots constitute a sub-frame of length 1 ms

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 in Bullets 2nd BW symbol of time slot 12 (subframe 6) o subframe 1 is always a special subframe so the PSS is sent as part of the Downlink Pilot Time Slot (DwPTS) o subframe 6, may or may not be a special subframe, depending upon the uplink-downlink subframe configuration. It is a special subframe for configurations 0, 1, 2 and 6.
