Abstract: Systems and methods for frequency reuse on downlink control channels (DLCCs) are provided. One method can include determining a first number of symbols to support transmission of control information on a DLCC, and configuring a second number of symbols for transmission of the control information on the DLCC, wherein the second number of symbols is greater than the first number of symbols. The method can also include assigning a number of DLCCs based on the second number of symbols, and transmitting control information over an assigned number of DLCCs to achieve an effective reuse factor less than one. Another method can include identifying fractions of bandwidth in a system having cells, and allocating at least one of the cells to at least one of the fractions of bandwidth in a system. Resource element groups allocated to the fractions of bandwidth can be coordinated across cells to provide frequency reuse.
