Apparatuses, methods, and computer program products for communication

A method of communication, the method comprising:

• receiving a data packet comprising a plurality of space-time streams and a plurality of fields each indicating a number of space-time streams associated with a position information;
• determining a position information assigned to the apparatus;
• determining how many of the plurality of space-time streams in the data packet are destined to the apparatus based on a field indicating a number of space-time streams associated with the position information assigned to the apparatus;
• when the position information assigned to the apparatus does not have a lowest possible value, determining that the field indicating the number of space-time streams associated with the position information assigned to the apparatus is preceded by one or more other fields indicating a number of space-time streams associated with position information different from the position information assigned to the apparatus;
• considering a value of each of the one or more other fields that precede the field indicating the number of space-time streams associated with the position information assigned to the apparatus to determine which of the plurality of space-time streams in the data packet are destined to the apparatus;
• and
• processing one or more space-time streams destined to the apparatus.

A non-transitory computer-readable medium comprising code for:

• receiving a data packet comprising a plurality of space-time streams and a plurality of fields each indicating a number of space-time streams associated with a position information;
• determining a position information assigned to the apparatus;
• determining how many of the plurality of space-time streams in the data packet are destined to the apparatus based on a field indicating a number of space-time streams associated with the position information assigned to the apparatus;
• when the position information assigned to the apparatus does not have a lowest possible value, determining that the field indicating the number of space-time streams associated with the position information assigned to the apparatus is preceded by one or more other fields indicating a number of space-time streams associated with position information different from the position information assigned to the apparatus;
• considering a value of each of the one or more other fields that precede the field indicating the number of space-time streams associated with the position information assigned to the apparatus to determine which of the plurality of space-time streams in the data packet are destined to the apparatus;
• and
• processing one or more space-time streams destined to the apparatus.
