Abstract
Methods and apparatus are provided. In an example aspect, a method in a wireless communication device of precoding symbols for transmission is provided. The method includes determining an indication of distortion of symbols transmitted by transmission apparatus of the wireless communication device or an indication of a correction for the distortion, determining precoding parameters based on the indication of distortion or the indication of the correction, and precoding symbols to be transmitted based on the precoding parameters.
Claims20
A method in a wireless communication device of precoding symbols for transmission, the method comprising:
- determining an indication of distortion of symbols transmitted by transmission apparatus of the wireless communication device or an indication of a correction for the distortion;
- determining precoding parameters based on the indication of distortion or the indication of the correction;
- and
- precoding symbols to be transmitted based on the precoding parameters.
A method in a first wireless communication device of determining precoding parameters, the method comprising:
- receiving one or more precoded symbols from a second wireless communication device;
- determining an indication of distortion of the precoded symbols by transmission apparatus of the second wireless communication device or an indication of a correction for the distortion;
- and
- causing the second wireless communication device to determine precoding parameters based on the indication of distortion or the indication of the correction.
An apparatus in a wireless communication device for precoding symbols for transmission, the apparatus comprising a processor and a memory, the memory containing instructions executable by the processor such that the apparatus is operable to:
- determine an indication of distortion of symbols transmitted by transmission apparatus of the wireless communication device or an indication of a correction for the distortion;
- determine precoding parameters based on the indication of distortion or the indication of the correction;
- and
- precode symbols to be transmitted based on the precoding parameters.
