Abstract
A system, method (), and network node () is presented for setting the size of a control region, the PDCCH region () of a subframe (). The PDCCH control region may have a size, indicated by the Control Format Indicator, CFI, transmitted on the PCFICH, that varies between 1 and 3 OFDM symbols. The network node () may select () an initial size for the control region (), and determine () whether the initial size for the control region is less than a predetermined maximum control region size. In response to determining that the initial size is less than the predetermined maximum control region size, the network node () selects () a final size for the control region () based on a data region load. The data region load indicates a load on all physical downlink shared channels, PDSCHs, on all enhanced PDCCHs, ePDCCHs, in the data region. After selecting the final size for the control region, the network node () transmits () the subframe (), wherein the control region of the subframe comprises information identifying the selected final size, and the size of the control region is equal to the selected final size.
