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. 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

Whereas 10 ms periodicity frame has only one Special subframe as subframe #1 . A Special subframe has three past DwPTS(Downlink Pilot Time Slot),GP (Guard Period) and UpPTS (Uplink Pilot Time Slot) and all of these have configurable lengths while the sum of the lengths has to be 1 ms or 14 symbols. 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. Technical Evaluation of TD-LTE for Low-band Spectrum • Some of the notable drawbacks of TD-LTE in low-frequency spectrum include link budget deficits compared to FDD LTE, performance constraints compared to FDD LTE, and real-world limitations on the feasibility of variable downlink-uplink configurations • Compensating for the difference in coverage between FDD LTE and TD-LTE is very difficult Technical Evaluation of TD-LTE for Low-band Spectrum well as Downlink and Uplink Pilot Timeslots • In addition to control information. Downlink Pilot Time Slot (DwPTS) can carry data • The smaller the GP, the higher the DL capacity DL UL Special Downlink subframe Uplink DwPTS GP UpPTS

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. 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.
