As the world grows in technology, demand of higher data rates increases. LTE and LTE-Advanced systems offer high data rates with low latencies. Some technologies used in LTE and LTE-Advanced systems depend on the performance of the control channels PDCCH and enhanced PDCCH. One of the main operations in the control channels is the search space allocation scheme, in which the UE performs blind decoding to search for control information intended for it. The work and study done in this thesis targets the development of the standard search space allocation scheme into a more scattered design to decrease the blocking probability of all UEs in the cell; and hence allows for more enhancement and developments in the data rates. The proposed scattered search space design of the allocation scheme offered better performance than the standard search space design and other schemes proposed in various research papers.
