LTE Frame and Subframe Structure - CableFree 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.
4G LTE frame Downlink with MIMO reference signals. 2X2 MIMO.
Scheduling is done on a subframe basis for both the downlink and uplink. Each subframe consists of two equally sized slots of 0.5 ms in length ( Tslot = 15360 · Ts). Each slot in turn consists of a number of OFDM symbols which can be either seven (normal cyclic prefix) or six (extended cyclic prefix). LTE Allocation Editor - Keysight Uplink. The odd-numbered slot's PUCCH allocation will automatically be set according to the LTE standard (mirrored in frequency). For example, in a 5 MHz LTE signal (25 RBs), when Slot 0 contains a PUCCH allocation at RB 0, Slot 1 will be set to have a PUCCH allocation at RB 24. What is special sub frame in LTE? - Telecom Source 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. Technical Evaluation of TD-LTE for Low-band Spectrum

THE LTE DwPTS (Downlink Pilot Time Slot) and UpPTS (Uplink Pilot Time Slot) provide control channel information and GP (Guard Period) is theWith LTE TDD, the shared channel structure between the downlink and the uplink means that not every single sub-frame is available to support PHICH/PUCCH.

Design and Implementation of Spatial Interweave LTE-TDD ... - Eurecom LTE is a “near 4G” standard, providing downlink (DL, from base station to ..... ( PSS/SSS), the guard period (GP), and the DL/UL pilot time slot Dw/Up-PTS.
LTE Allocation Editor - Keysight The LTE Allocation Editor dialog is used to define user mappings. There are two different versions of this dialog for both uplink and downlink depending on the RB Auto Detect setting. When RB Auto Detect is selected, the LTE Allocation Editor will only show the parameters needed for successful demodulation. 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 - DolceraWiki LTE (Long Term Evolution), is the latest standard in the mobile network technology that came into existence because of the growing needs of faster data rates. It is a 3rd Generation Partnership Project (3GPP), which realized this technology. LTE is an advancement to previously realized technologies such as GSM/EDGE and UMTS/HSxPA etc. LTE Physical Layer Overview | Downlink
