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 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. Downlink Slot Structure | Radio Interface Basics 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. LTE Device Requirements for Verizon Wireless

Jul 07, 2018 · 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: LTE Frame Structure - worldoflte.blogspot.com Nov 10, 2014 · 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 … LTE Frame Structure | Type 1 Type 2| Electronics Notes Type 2 LTE Frame Structure. UpPTS - Uplink Pilot Time Stot.

UMTS UTRA time slot example UMTS Time Slots UMTS has several different time slot configuration depending on the used channel. Here is an example of DPCH (Dedicated Physical Channel) downlink and uplink time slot allocation. TCP stands for Transmit Power Control, Feedback Information (FBI) is used for closed loop transmission diversity. FDD and TDD Duplexing - MATLAB & Simulink
How Time Slot Allocation for Uplink and Downlink LTE. This will have a direct impact on the EUTRAN capacity. There are 7 time sharing configuration between Uplink and Downlink in LTE TDD as defined by 3GPP. They are shown in the figure below and in summary, they are (DL : UL) – 1:3 or 2:2 or 3:1 or 2:1 or 7:2 or 8:1 or 3:5.
