Abstract
A method of transmitting signals by a transmitting end in a wireless communication system comprises sharing control information related to reference signal with a receiving end; generating one or more precoded reference signals considering a given rank; allocating the one or more precoded reference signals to have a specific pattern within a subframe, wherein the specific pattern is varied depending on the control information; and transmitting the subframe through multiple antennas to the receiving end.
Claims13
A method of transmitting signals by a user equipment in a wireless communication system, the method comprising:
- receiving control information;
- generating one or more precoded reference signals considering a given rank;
- allocating the one or more precoded reference signals to have a specific pattern within a subframe, wherein the specific pattern is dependent on the control information;
- and
- transmitting the subframe through multiple antennas,
- wherein, if the given rank is 3 or higher, the subframe is transmitted using an orthogonal frequency division multiple access (OFMDA) scheme and the one or more precoded reference signals are allocated non-continuously in frequency, and
- wherein, if the given rank is 2 or lower, the subframe is transmitted using a single carrier frequency division multiple access (SC-FDMA) scheme and the one or more precoded reference signals are allocated continuously in frequency.
