Pradeep 10 Comments Just thought of writing a small note on how aggregation level controls PDCCH decoding and its importance in a wireless channel. As we saw from the previous section, the number of bits that can be accommodated are different in each of the aggregation levels and as we know the number of bits in each of the DCI formats are less than the number of bits shown above.

Lets take a example of DCI format 1A for 10Mhz, the total number of bits after packing all the fields will be 25 and after adding the 16 bit CRC, this will add upto 41 bits. Now the scheduler will have to decide, which aggregation to be used for a DCI format and it takes that decision based on following factors, Worst case scenario — this factor is considered for all the common DCIs such as SIB, RAR, Paging etc and the reason for assuming the worst case is, these DCIs are supposed to be decoded by all the UEs connected to the eNodeB, no matter how far or near they are to the eNodeB, hence most likely the scheduler will use the highest possible aggregation level of 8 to schedule these DCIs, so for the above example of DCI 1A, the 41 bits are rate matched and bloated to bits giving a very good forward error correction protection for these bits.

The answer is capacity. Higher the aggregation level, more number of subcarriers are required for a given user, hence reducing the amount of space available in the control channel for other UE DCIs, which in turn will control how many users the scheduler will be able to schedule in the given subframe.

So the scheduler has to trade-off between efficiency and capacity.TE Elektronik, Elektrik-Elektronik Sektörünün önemli bir bölümünün yer aldığı Ankara’ da kurulmuştur. 15 yıllık Tecrübemizle birlikte tüm Elektronik üreticilerine ve AR-GE Merkezlerine hizmet vermekteyiz.

What is Long Term Evolution (LTE)? - Definition from Techopedia

Mobile business, CBS [email protected] • L-F Pau, Reproduction. LTE Advanced is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard.

It was formally submitted as a candidate 4G to ITU-T in late as meeting the requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation Partnership Project in March as 3GPP Release When you’re looking to buy a new phone, you might find that there are way too many acronyms to choose from, between CDMA, GSM, LTE, and WiMax; the list goes on.

Rohde & Schwarz's presentations provide an excellent introduction to presentations are accompanied with an audio narration. The topics covered are: LTE . In telecommunication, Long-Term Evolution (LTE) is a standard for high-speed wireless communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies.

It increases the capacity and speed using a different radio interface together with core network improvements. The standard is developed by the 3GPP (3rd Generation Partnership Project) and is .
