Please find below some basic terms used in LTE - a short description.

Resource Element (RE): the smallest unit made up of 1 symbol x 1 subcarrier

Resource Element Group (REG): a group of 4 consecutive resource elements (resource elements for reference signal is not included in REG)

Control Channel Element (CCE): a group of 9 consecutive REG

RB (Resource Block): I think everybody would know what this is. This is a unit of 84 resource elements which is 12 subcarrier by 7 symbols (this is with normal a Cyclic Prefix which is used in most of the LTE deployment. If it is with an Extended Cyclic Prefix, the number of symbols within a sub frame become 6 and the number of resource elements in a single RB become 72).

RBG (Resource Block Group): This is a unit comprised of multiple RBs. How many RBs within one RBG differs depending on the system bandwidth.
