Abstract
A method and apparatus for transmitting a signal for channel estimation through a plurality of antennas are provided. A plurality of resources that are adjacent to each other in a time axis and a frequency axis are selected from among a set of resources that include a symbol in the time axis and a subcarrier in the frequency axis. Reference signals for the plurality of antennas are transmitted through the selected plurality of resources.
Claims18
A method of transmitting a signal for channel estimation through a plurality of antennas, the method comprising:
- selecting a plurality of resources that are adjacent to each other in a time axis and a frequency axis, from among a set of resources that include a symbol in the time axis and a subcarrier in the frequency axis;
- and
- transmitting reference signals for the plurality of antennas through the selected plurality of resources.
An apparatus for transmitting a signal for channel estimation through a plurality of antennas, the apparatus comprising:
- a radio frequency converter for transmitting and receiving a signal through the plurality of antennas;
- and
- a processor that is connected to the radio frequency converter and controls transmitting for a reference signal for channel estimation,
- wherein the processor includes a resource selector that selects a plurality of resources that are adjacent to each other in a time axis and a frequency axis, from among a set of resources that include a symbol in the time axis and a subcarrier in the frequency axis, and
- an orthogonal code applier that applies an orthogonal code to each of reference signals for the plurality of antennas transmitted through the selected plurality of resources.
