A computer language based on C that uses objected-oriented programming (OOP) design principles. Now let's magnify the structure even further, but this time expand in frequency domain, not in time domain. Now you see that one slot is made up of 7 small blocks called 'symbol'. A physical controlchannel is transmitted on an aggregation of one or several consecutive control channel elements (CCEs), where a control channel element corresponds to 9 resource element groups. The physical downlink control channel carries scheduling assignments and other control information. Here goes, Followings are examples for various TDD UL/DL configurations. The PDCCH supports multiple formats as listed in Table 6.8.1-1. I don't find much details on this as of 36.211 V13.1.0. A couple of things to be noticed about the subframe structure illustrated above is, Following shows the overal subframe structure from "LTE Resource Grid" (I realized that this site is not available any more. google_ad_slot = "5650141978"; Let's call this type of unit a two-dimensional unit.
