Anand TechnoSolutions's video: Carrier Aggregation in LTE Part-3

Each aggregated carrier is referred to as a component carrier, CC. The component carrier can have a bandwidth of 1.4, 3, 5, 10, 15 or 20 MHz and a maximum of five component carriers can be aggregated, hence the maximum aggregated bandwidth is 100 MHz. In FDD the number of aggregated carriers can be different in DL and UL, see figure 1. However, the number of UL component carriers is always equal to or lower than the number of DL component carriers. The individual component carriers can also be of different bandwidths. For TDD the number of CCs as well as the bandwidths of each CC will normally be the same for DL and UL. The easiest way to arrange aggregation would be to use contiguous component carriers within the same operating frequency band , so called intra-band contiguous. This might not always be possible, due to operator frequency allocation scenarios. For non-contiguous allocation it could either be intra-band, i.e. the component carriers belong to the same operating frequency band, but have a gap, or gaps, in between, or it could be inter-band, in which case the component carriers belong to different operating frequency bands, see figure 2. Aggregated Transmission Bandwidth Configuration : total number of aggregated physical resource blocks . CA bandwidth class: indicates a combination of maximum ATBC and maximum number of CCs. In R10 and R11 three classes are defined: CA configuration: indicates a combination of E-UTRA operating band and CA bandwidth class, to exemplify the configuration CA_1C indicates intra-band contiguous CA on E-UTRA operating band 1 and CA bandwidth class C, CA_1A_1A, indicates intra-band non-contiguous CA on band 1 with a one CC on each side of the intra-band gap, finally CA_1A-5B indicates inter-band CA, on operating band 1 with bandwidth class A and operating band 5 with bandwidth class B.

I am available here for support you and always uploading video for you. I am working in wireless technology where what i learn same knowledge, technology and technical things shared with you in video format. Apart from Technology my involvement in creating on-line money and also learn related to some technical and social things which is my Learning Habit, I do not want to keep these things confined to myself. I would be glad if my video would be a helpful for you. ➽ If any part of the contents of this channel is that your property (as a musician, label, video, image distributor or artist), please send me a personal message and your content will be removed within 24 hours.
