Downlink Pilot Time Slot UpPTS Uplink Pilot Time Slot GP Guard period LTE Physical Layer Overview - Keysight RFMW Sitemap LTE Physical Layer Overview. There are two types of frame structure in the LTE standard, Type 1 and Type 2. Type 1 uses Frequency Division Duplexing (uplink and downlink separated by frequency), and TDD uses Time Division Duplexing (uplink and downlink separated in time). This overview covers both LTE FDD Type 1 signals and LTE TDD Type 2 signals described in the standard documents listed in ... 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. 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.

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.
The special subframe (subframe 1 in every uplink-downlink configuration, and subframe 6 in uplink-downlink configurations 0, 1, 2 and 6) contains a portion of downlink transmission at the start of the subframe (the Downlink Pilot Time Slot, DwPTS), a portion of unused symbols in the middle of the subframe (the Guard Period) and a portion of uplink transmission at the end of the subframe (the ...

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.
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. TD-LTE: Greater Flexibility, New Challenges prevent overlap between uplink and downlink signaling, TD-LTE uses a Guard Period (GP, as shown in Figure 1) in which no data is transmitted. The GP occurs inside the special subframe, which also includes a variable amount of downlink information in the Downlink Pilot Time Slot (DwPTS) and uplink signaling in the Uplink Pilot Time Slot (UpPTS).

The Physical Broadcast Channel is the as LTE FDD as well. 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.
