Data transmission in communication system by disabling radiation patterns

A method, comprising:

• processing a signal including symbols from a transmitter by using Nr receive radiation patterns, the symbols being transmitted so that information content of a symbol of temporal length T is transmitted using the at least two transmit radiation patterns;
• disabling N receive radiation patterns, wherein 1<=N<Nr from the processing of the signal so that Nr−N effective receive radiation patterns are formed;
• processing the signal adapted to Nr−N effective receive radiation patterns so that transmit radiation patterns or the number of symbols in a time interval of length T when receiving with Nr−N effective receive radiation patterns is less than or equal to a separate number of symbols received in a time interval of length T when an apparatus performing the processing is processing the signal received with Nr receive radiation patterns;
• and
• processing each symbol distributed over at least two transmit radiation patterns by beam-forming wherein the apparatus is configured to process the signal as adapted to a reduced number of receive radiation patterns of the apparatus by changed beam-forming weights.

A computer-readable medium encoded with instructions that, when executed in hardware, cause the hardware to perform a process, the process comprising:

• processing a signal including symbols from a transmitter by using Nr receive radiation patterns, the symbols being transmitted so that information content of a symbol of temporal length T is transmitted using the at least two transmit radiation patterns;
• disabling N receive radiation patterns, wherein 1<=N<Nr from the processing of the signal so that Nr−N effective receive radiation patterns are formed;
• processing the signal adapted to Nr−N effective receive radiation patterns so that transmit radiation patterns or the number of symbols in a time interval of length T when receiving with Nr−N effective receive radiation patterns is less than or equal to a separate number of symbols received in a time interval of length T when an apparatus performing the processing is processing the signal received with Nr receive radiation patterns;
• and
• processing each symbol distributed over at least two transmit radiation patterns by beam-forming wherein the apparatus is configured to process the signal as adapted to a reduced number of receive radiation patterns of the apparatus by changed beam-forming weights.
