Difference between PUCCH and PUSCH

I was asked by many engineers on PUCCH and PUSCH functionality and major difference. This thread describes PUCCH functionality and PUSCH functionality. I have tried to differentiate major difference between PUCCH and PUSCH where possible.After reading entire post reader can conclude PUCCH vs PUSCH. PUCCH :  The Physical Uplink Control Channel (PUCCH) is used to transfer Uplink Control Information (UCI). UCI can also be transferred using the PUSCH.  Please refer Different Channel State Information (CSI) Reporting Types. The release 8 and 9 versions of the 3GPP specifications do not allow an individual UE to transmit both the PUCCH and PUSCH during the same sub frame. For Release 8 and 9 if UE has application data or RRC signalling than UCI information transmitted via PUSCH. The release 10 version of the 3GPP specifications introduces the option to support simultaneous PUCCH and PUSCH transmission. 3GPP specify 7 PUCCH formats.Different PUCCH formats are 1,1a,1b,2,2a,2b,3. The P

LTE Measurements Understanding

Image
There are several IEs to configure measurement control in detail, which are under measConfig IE in RRC Connection Reconfiguration message. They are not clearly described with specific picture but here is what I understand. Form the top picture, we might think of an ideal case as (neighbour) cell measured value in yellow goes up linearly. Threshold is bottom line and offset (including several kinds of sub-offset values though) and hysteresis can be applied. Entering condition in this case would mean yellow line cross over threshold (+hysteresis) with blue "x" mark. From this point, timeToTrigger and reportInterval can be applied through the blue block. Leaving condition in this case could not be applied because it never get down go threshold (-hysteresis) as grey "x" mark. If measConfig needs to be removed, it can be managed by RRC Connection Reconfiguration procedure. From the bottom one, we can think of entering and leaving condition with blue "x

eNB Functionalities

eNodeB The eNB element of LTE is responsible for radio transmission and reception with UE. eNB  provides the required functionality for the radio resource management (RRM), including  admission control, radio bearer control, scheduling of user data, and control signaling over  the air interface. In addition, eNB takes care of the ciphering and header compression over the  air interface. The clearest difference between UTRAN and E-UTRAN can be seen in the role of the base  station. The eNodeB of LTE now includes basically all the functionalities that were previously  concentrated on the RNC of the UTRANsystem. In addition, the traditional tasks of the NodeB  are still included in the new eNodeB ( eNB ) element. eNB works thus as the counterpart of the  UE in the radio interface but includes procedures for decision making related to the connections. This solution results in the term “flat architecture” of LTE, meaning that there are less  interfaces and only one element in
