in legacy systems such as 3 rd generation partnership project releases 8 to 10 , the control channel is transmitted using the first few orthogonal frequency division multiplexing symbols in a subframe . the limited control channel capacity will impact the system performance in future releases as more and more user equipments will be scheduled in a subframe with technologies such as mulituser - multiple input multiple output and coordinated multipoint transmission being enhanced or introduced . a new enhanced control channel is necessary to be designed , which will use the resource in the physical downlink shared channel in the legacy systems . the e - cch will support ue - specific demodulation reference signal based transmission and receiving . however , the configuration of dmrs for e - cch is necessary to be known to ue in prior . this invention discloses multiple methods in which dmrs is configured for e - cchs and respective enb and ue behaviors .
