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

Downlink Packet Scheduling in LTE Cellular | time A time/frequency radio resource spanning over two time slots in the time domain and over one sub-channel in the frequency domain is called Resource Block (RB) andallowing simultaneous downlink and uplink data transmissions, and the LTE frame is composed of 10 consecutive identical sub-frames. Unified access in licensed and unlicensed bands in LTE-A… The existing Downlink Pilot Time Slot (DwPTS) structure is reused where DwPTS is the DL portion ofDue to the time uncertainty associated with channel access, Rel-14 eLAA supports flexible timing between the subframe of an uplink grant transmission and the subframe of an associated PUSCH... What is special sub frame in LTE? | Forum 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. LTE-Advanced. A Practical Systems Approach to Understanding…

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.

Throughput Evaluation of Downlink Multiuser-MIMO OFDM-LTE System.Special sub frame has 9 different configurations [8]. A special sub frame is divided into Downlink Pilot Time Slot (DwPTS), Guard Period (GP) and Uplink Pilot Time Slot (UpPTS) depending upon the number of symbols. In TDD-LTE how time slot allocation being done for both uplink… 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 bothBesides time sharing configuration, there is also a need to define how uplink and downlink pilots are configured based on the Guard band requirement.
