First communication device, second communication device and methods therein for sending and decoding, respectively, downlink information

Abstract:

Method performed by a first communication device (101) for sending downlink information to a second communication device (102). The first communication device (101) and the second communication device (102) operate in a communications network (100). The first communication device (101) determines (702) whether or not one or more third communication devices (103) operating in the communications network (100) are sending uplink information on an adjacent carrier (142). The adjacent carrier (142) is adjacent to a carrier (141) assigned to the first communication device (101) for sending the downlink information to the second communication device (102). The first communication device (101) sends (703) the downlink information to the second communication device (102) on the carrier (141) when it has determined that the one or more third communication devices (103) are not sending uplink information on the adjacent carrier (142) to the carrier (141).
