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.

Claims

1. An apparatus for communication, the apparatus comprising:

a memory; and

at least one processor associated with the memory and configured to;

transmit a frame configured to assign first position information for a first identifier; and

transmit a data packet associated with a second identifier,

wherein the data packet comprises a number of space-time streams associated with the first position information and destined to a destination, the data packet further comprising a number of space-time streams associated with second position information, the second position information comprising a value different from a value of the first position information, the number of space-time streams associated with the second position information determining which one or more space-time streams in the data packet is destined to the destination, the data packet further comprising a data portion configured to be processed at the destination when the second identifier with which the data packet is associated corresponds to the first identifier for which the first position information was assigned by the frame.

2. The apparatus of claim 1, wherein the frame is individually addressed to the destination.

3. The apparatus of claim 1, wherein the data portion is further configured not to be processed at the destination when the second identifier with which the data packet is associated does not correspond to the first identifier for which the first position information was assigned by the frame.

4. The apparatus of claim 1, wherein one or more space-time streams in the data packet is destined to the destination when the second identifier with which the data packet is associated corresponds to the first identifier for which the first position information was assigned by the frame.

5. The apparatus of claim 1, wherein one or more space-time streams destined to a first destination begins concurrently with one or more space-time streams destined to a second destination different from the first destination.

6. The apparatus of claim 1, wherein the data packet is a multi-user data packet when the second identifier has one of a first subset of values, and wherein the data packet is a single-user data packet when the second identifier has one of a second subset of values.

7. The apparatus of claim 1, wherein the data packet further comprises a reference symbol and a subsequent symbol, wherein the data packet is a very high throughput (VHT) data packet rather than a non-VHT data packet when the subsequent symbol has a 90°

counter-clockwise rotation relative to the reference symbol.

8. The apparatus of claim 1, wherein a number of data portions destined to one or more destinations is greater than a number of space-time streams available in a single data packet.

9. The apparatus of claim 1, wherein the data packet further comprises timing information indicating at least an end of a data portion destined to a first destination or a beginning of a data portion destined to a second destination.

10. The apparatus of claim 1, wherein the frame is further configured to replace one or more values stored at the destination with one or more values in the frame.

11. The apparatus of claim 1, wherein at least one space-time stream in the data packet comprises a first data portion destined to a first destination and a second data portion destined to a second destination.

12. The apparatus of claim 1, wherein the frame is transmitted to the destination at a first time different from a second time at which a second frame addressed to another destination is transmitted.

13. The apparatus of claim 1, wherein the data packet includes an abbreviated indication of the destination when the data packet is a single-user data packet.

14. The apparatus of claim 1, wherein the first position information is assigned by the frame according to a quality of service of data destined to the destination.

15. The apparatus of claim 1, wherein the frame is further configured to assign position information for each identifier to which the destination is a member.

16. The apparatus of claim 1, wherein the data packet further comprises:

a first portion indicating a number of space-time streams associated with the first position information; and

a second portion indicating a number of space-time streams associated with the second position information.

17. The apparatus of claim 1, wherein position information assigned to a first destination is the same as position information assigned to a second destination.

18. The apparatus of claim 1, wherein the data packet further comprises a stack bit indicating that two or more data portions are included in at least one space-time stream of the data packet.

19. The apparatus of claim 1, wherein one or more space-time streams in the data packet are configured not to be processed at the destination when the second identifier with which the data packet is associated does not correspond to the first identifier for which the first position information was assigned by the frame.

20. The apparatus of claim 1, wherein the number of space-time streams destined to the destination is based on the first position information assigned by the frame.
