TDD LTE Frame Structure - forum.huawei.com And there comes a Special subframe which comes when there is transition from downlink subframe to uplink subframe. It has three parts – DwPTS(Downlink Pilot Time Slot),GP (Guard Period) and UpPTS (Uplink Pilot Time Slot) and all of these have configurable lengths, which depends upon Special subframe configuration. Further Development of LTE Advanced Release12 Standardization ... in time, between the DL and the UL. Note that when switching from DL to UL, a Special subframe*9 is inserted, incorporating a DL reception period Downlink Pilot Time Slot (DwPTS), a Guard Period (GP), and an UL trans-mitting period Uplink Pilot Time Slot (UpPTS). In LTE, seven UL/DL config-urations with different subframe up- RESEARCH ON PILOT BASED CHANNEL ESTIMATION FOR LTE DOWNLINK It is composed of 20 slots of 0.5 ms described in figure 1. .Each time slot consists of either 7 or 6 OFDM symbols depending on the length of the CP (normal or extended). In LTE Downlink physical layer, 12 consecutive subcarriers are grouped into one Physical Resource Block (PRB). A PRB has the duration of 1 time slot. SC-FDMA & OFDMA in LTE physical layer

3GPP radio-access technology will be highly competitive for several years. However, to ensure competitiveness in an even longer time frame, i.e. for the next 10 years and beyond, a long-term evolution of the 3GPP radio-access technology needs to be considered.” l Basic drivers for LTE have been: l Reduced latency l Higher user data rates Precoded transmission in TDD mode for LTE-A Uplink Precoded transmission in TDD mode for LTE-A Uplink Project period: February – June 2010 ... UpPTS Uplink Pilot Time Slot DwPTS Downlink Pilot Time Slot VIII. LIST ... (PDF) LTE-Network-Planning-HUAWEI.pdf | Husnul Fuady ... Contents Name LTE Network Planning Purpose To Introduce the LTE basic principle, network planning method and RNP solution Key Message LTE has the flat network architecture and physical layer applies OFDM technology, as well as the MIMO, ICIC, etc. LTE network planning includes coverage, capacity planning.
LTE TDD Special Subframe and Its significance for Cell
The basic type 1 LTE frame has an overall length of 10 ms. This is then divided into a total of 20 individual slots. LTE Sub-frames then consist of two slots - in other words there are ten LTE sub-frames within a frame. What is LTE frame structure? - Quora

UpPTS - Uplink Pilot Time Slot - Certified Training 5G 4G LTE ... UpPTS - Uplink Pilot Time Slot In LTE , the radio frame structure type 2 is used for TDD operation and consists of two half-frames with a duration of 5ms each and containing each 8 slots of length 0.5ms and three special fields ( DwPTS , GP and UpPTS) which have configurable individual lengths and a total length of 1ms. How Time Slot Allocation for Uplink and Downlink LTE ... Time Slot Allocation for Uplink and Downlink – TDD specific. The time division nature of LTE TDD will also require radio engineers to consider how time slots are shared between uplink and downlink based on both customer input as well as commercial users usage pattern between uplink and downlink in that country. LTE FDD frame structure | LTE Tutorial - RF Wireless World LTE Frame structure. The LTE frame structure are of two types based on topology either FDD or TDD. Total Frame duration is about 10ms. There are total 10 subframes in a frame. Each subframe composed of 2 time slots. Type 1, LTE frame structure is applicable to FDD system. LTE TDD Technology Overview - SlideShare
Type 2 LTE Frame Structure. 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 – A Technical Overview 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 Kalman interpolation filter for channel estimation of LTE ... As depicted in Figure 1, a radio frame of the LTE downlink has duration of 10 ms and consists of ten subframes each of 1 ms.Each subframes has two 0.5-ms time slots with each slot consisting of N symb DL Open image in new window OFDM symbols (the values of N symb DL Open image in new window for various configurations are given in Table 1).
