Abstract

Apparatuses, methods, and computer program products for communication are provided. In an aspect, an apparatus for communication may include a processing system configured to receive a frame configured to assign at least member information or position information for one or more identifiers, and receive a data packet associated with a particular identifier and indicating a number of space-time streams for one or more position information. In another aspect, an apparatus for communication may include a processing system configured to transmit a frame configured to assign at least member information or position information for one or more identifiers, and transmit a data packet associated with a particular identifier and indicating a number of space-time streams for one or more position information.

process one or more space-time streams of the plurality of space-time streams in the data packet.

2. The apparatus of claim 1, wherein each of the one or more other fields indicating the number of space-time streams associated with the one or more other position information different from the position information assigned to the apparatus are different from the field indicating the number of space-time streams associated with the position information assigned to the apparatus.

3. The apparatus of claim 1, wherein each of the one or more other position information different from the position information assigned to the apparatus comprise a value that is lower than a value of the position information assigned to the apparatus.

4. The apparatus of claim 1, wherein a value of each of the one or more other fields indicating the number of space-time streams associated with the one or more other position information different from the position information assigned to the apparatus is equal to or greater than a value of the field indicating the number of space-time streams associated with the position information assigned to the apparatus.

5. The apparatus of claim 1, wherein the data packet is associated with an identifier, and wherein the identifier is associated with the number of space-time streams associated with the position information assigned to the apparatus.

6. The apparatus of claim 1, wherein the plurality of space-time streams comprise at least:

one or more space-time streams destined to the apparatus and one or more space-time stream destined to one or more other apparatus.

7. The apparatus of claim 1, wherein the plurality of space-time streams comprises at least two space-time streams destined to different apparatus.

8. The apparatus of claim 1, wherein the data packet is a multi-user data packet addressed or destined to more than one apparatus.

9. A method of communication by an apparatus, the method comprising:

receiving a data packet comprising a plurality of space-time streams;

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;

if the position information assigned to the apparatus has 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 not preceded by one or more other fields indicating a number of space-time streams associated with one or more other position information different from the position information assigned to the apparatus;

if the position information assigned to the apparatus does not have the 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 one or more other position information different from the position information assigned to the apparatus;

if the position information assigned to the apparatus does not have the lowest possible value, considering a sum of values in 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 to process; and
