What is Pucch and Pusch in LTE?
The LTE uplink physical layer has a triplet of physical channels; Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH) and Physical Random Access Channel (PRACH). The PUSCH is used for transmitting user traffic data in multiplex with Uplink Control Information (UCI), if necessary.
How is Pucch format calculated?
1-1. You may notice that 38.213 Table 9.2. 1-1 defines the pucch format and time domain resource allocation but it does not specify the exact frequency domain resource allocation….What is PUCCH Resource and what constitues it?
| Parameter | Applicable PUCCH Format |

What is the difference between Pucch and Pusch?
The PUSCH carries RRC signaling messages, UCI (uplink Control Information), and application data. The PUCCH format 1 is used to carry uplink control information (UCI) pertaining to scheduling requests and HARQ. The PUCCH format 2 is used to carry uplink control information (UCI) pertaining to CQI and HARQ.
What is UCI in LTE?
UCI stands for Uplink Control Information. It is carried by PUCCH or PUSCH. It may remind you of DCI which is carried by PDCCH.
What are Pucch formats?
The Physical Uplink Control Channel (PUCCH) Format 2 is a transmission channel used to carry information regarding channel status reports as well as Hybrid Automatic Repeat request (HARQ) acknowledgements.
What is Pucch?
In LTE, data can be transmitted from the eNodeB to the UE via a physical downlink shared channel (PDSCH). A physical uplink control channel (PUCCH) can be used to acknowledge that data was received.
What is LTE Pucch?
PUCCHPhysical Uplink Control Channel is the Physical Uplink Control Channel and carries uplink control information including channel quality info, acknowledgements, and scheduling requests.
What is Pucch format in LTE?
PUCCH (Physical Uplink Control Channel) carries a set of information called “UCI(Uplink Control Information)”. (This is similar to PDCCH which carries DCI (Downlink control information)”. Depending on what kind of information the UCI in PUCCH carries, PUCCH is classified into various formation as follows.
Where is Pucch located?
For example, PUCCH is located only at the lowest and highest end in frequency domain and reference signals also localized in time domain or both timedomain and frequency domain. Carries the Reference Signal that is required for demodulating PUCCH.
What is LTE frame structure?
In LTE, DL and UL transmissions are organized into radio frames of 10 ms each. Each frame is divided into ten equally sized subframes. The duration of each subframe is 1 ms. Moreover, each subframe is further divided into two equally sized time slots, that is, each slot is 0.5 ms.
What is Pucch 5G?
• PUCCH channel is used to transport UCI (Uplink Control Information) e.g. HARQ feedback, CSI (Channel State Information) and SR (Scheduling Request). • 5G NR PUCCH is flexible in time domain and frequency domain.
What is Pdcch and Pdsch?
PDSCH — physical downlink shared channel. The PDSCH carries user data and paging information to the terminal. PDCCH — physical downlink control channel. The PDCCH conveys control information, scheduling decisions for PDSCH reception, and for scheduling grants enabling transmission on the PUSCH.
What is LTE Pusch?
This page describes LTE PUSCH channel or Physical Uplink Shared Channel with respect to LTE system. This channel is used to carry RRC signalling messages, UCI (uplink Control Information) and application data. Uplink RRC messages are carried using PUSCH.
What is UCI in 5G?
UCI (Uplink Control Information) is carried by PUCCH channel in 5G NR. UCI consists of HARQ (Hybrid Automatic Repeat Request) feedback, CSI (Channel State Information) and SR (Scheduling Request). Refer 5G NR PUCCH >> for more information. There are two types of PUCCH viz. short and long.
What is Pdcch format?
The Physical Downlink Control Channel (PDCCH) is primarily used to carry scheduling information to individual UEs, i.e., resource assignments for uplink and downlink data and control information. The PDCCH is located in the first few OFDM symbols of a subframe.
