TRANSMITTING RADIO EQUIPMENT, RECEIVING RADIO EQUIPMENT AND CORRESPONDING METHODS FOR COMMUNICATING USING A REFERENCE SIGNAL

摘要

Methods and transmitting and receiving radio equipments for transmitting and receiving a reference signal in a subframe where a portion of one or more multi-carrier modulation symbols that is included in the subframe is used for transmitting control information to receiving radio equipments. The transmitting radio equipment transmits the reference signal overlaid on at least a part of the portion of the one or more multi-carrier modulation symbols that is used for transmitting the control information in the subframe. The reference signal is generated based on at least one parameter. The receiving radio equipment then receives a transmission including the control information and the reference signal in the subframe, and may determine one or more properties of the reference signal based on the at least one parameter and process the reference signal using the determined one or more properties of the reference signal.
